    IMPROVEMENTS INTRODUCED TO THE PATENT P201331917 BY “SYSTEM FOR THE TRANSVERSAL CONFINEMENT OF CONCRETE PILLARS BY METAL COLLARIN”

    DESCRIPTION 5

    OBJECT OF THE INVENTION

    The purpose of this certificate of addition is to broaden the scope of protection of the procedure for the development and installation of a metal collar for the transverse confinement of structural concrete pillars of any section, based on pieces of rolled steel profile wings. in hot type "H" or "double T" from shrinkage and sharpness that are subjected to cuts, bends and welds until the required sections are obtained; to a new procedure for the development and installation of the aforementioned collar made this time to allow adequate support of metal beams on existing concrete pillars.

    The invention finds its scope in the repairs and structural reinforcements of buildings or civil works, specifically in the field of those actions in which an adequate connection between new metal beams 20 and the existing pillars is required.

    BACKGROUND OF THE INVENTION

    The series of metal parts that are presented, duly manipulated and joined, has as its main utility the ability to form formwork for high performance fluid mortars, also becoming a resistant assembly capable of serving as a reliable connection plane for new metal structures on existing reinforced concrete pillars.
     30
     The possibility of reusing leftover pieces of laminated profiles (wings of the "H" or "double T" type section) to construct construction systems that serve as a connection plan for new metal structures on reinforced concrete pillars of buildings is, without a doubt, the main interest of the invention presented here by its obvious impact, by a
    on the one hand, in reducing the cost of the raw material used and, on the other, in improving the environmental performance of construction processes.

    The set resulting from the union between them of the aforementioned recycled sheets object of the invention, has important advantages in relation to the purpose pursued and with respect to other techniques present in the state of the art as listed below:

    A. It is desired to have safety measures on healthy pillars that have sections adjusted for: 10
    to. To undertake research campaigns on its structure through tests based on destructive techniques to quantify, for example, the feasibility of subjecting it to a new state of loads.

    b. To be able to safely carry out demolitions that involve attending another 15 repairs or reinforcements in the same pillar such as sanitation of degraded areas and thus being able to at a later stage place the proposed modules as close as possible to their current geometry, as long as it is demanded by strict functional requirements
     twenty
    B. Guarantee of a correct manufacture and execution of both:

    to. The metal piece itself:

    • By requiring a blank assembly (prior assembly in the workshop and subsequent disassembly to take it to the work).

    • By allowing the execution of large weld seams (upward vertical arrangement), so there is full guarantee of their structural efficiency, whether they are carried out in the workshop or on site. 30

    b. As of the filling material:

    • Using a simple hopper, it allows a correct spillage of the
    mortar filling fluid and in phases.

    • The curved arrangement of the junction of the inner shoulder (stiffening rib) with the sheet favors the impossibility of coking of the mortar filling, while favoring its adhesion with the metal sheets.

    C. Provide the pillars in their encounter with the slabs of greater resistance against horizontal actions of all kinds (wind, earthquake, vehicle impacts ...).
     10
    D. Possibility of machining in the workshop a large part of the parts, and therefore greater economy in manufacturing.

    E. Cleaning in execution, easy to transport ... quick assembly.
     fifteen
    F. It constitutes the effective connection of metal structures when they are intended to rest on reinforced concrete pillars of any section.

    DESCRIPTION OF THE INVENTION
     twenty
    The present certificate of addition to the main patent P201331917 for "System for the cross-sectional confinement of concrete pillars by means of a metal collar" describes a system comprising the realization of an intermediate stage between stages a) and b) of the process described in the main patent which describes the stages of:
     25
    a) Identification of the area of the structural concrete pillar on which it is desired to act.

    b) Evaluation of available pieces of 'double T' laminated profiles as a result of the waste collected from other works already executed. Standardized metal sheets 30 of reduced heights, generally less than 300 mm. in a wide range of thicknesses, stiffened with a central rib that is also variable according to the cut you want to make. In this regard, it is important to indicate the possibility of admitting arched pertiles, that is to say, obtaining by means of displacement curved guide plates.

    c) Selection among the available profiles, the most suitable according to the structural requirements of the pillar to be repaired or reinforced.

    d) Calculation by means of a specific computer application of the longitudinal cutting line to be performed on the core of the selected profiles.

    e) Cleaning by blasting the selected profiles.

    f) Cross section of the profiles according to the dimensions of the pillar and the thickness 10 chosen for the mortar.

    g) Making a bevel at 45 ° at the ends of the soul of each profile.

    h) Identification of the optimal assembly process in terms of efficacy and efficiency 15 with respect to the elements to be welded in the workshop, with respect to what will be welded in the work itself.

    i) Welding execution planned in the workshop and assembly test.
     twenty
    j) Mounting on the pillar that is desired to act and execution of welds provided in the field until obtaining a perfectly solidary system with each other thanks to the impeccable quality of its components especially that of the curved joint executed in the original laminate of the piece, which It makes it possible, once welded together, to form the metal formwork that superimposed around structural concrete pillars, 25 generates a metal jacket with the capacity to repair and reinforce it.

    k) Once the set of profiles is mounted around the pillar, a mortar with controlled retraction and fluid or liquid consistency, preferably pre-dosed, is poured. 30

    The improvements introduced include the realization of an intermediate stage between stages a) and b) of preparation of the surface of the abutment comprising the realization of a superficial pitting in the area of stage a) and the formation, in said area, of a number
    determined of slots destined to receive the soul of the profiles.

    In this regard it is important to highlight how the joining process, until forming a basic module composed of four plates, is carried out by welding adjacent plates according to continuous bead on their sides in contact as well as in bevel also in 5 contact practiced in the soul of both plates.

    The series of metal parts that are presented, properly manipulated and joined, have as main utility the ability to form formwork for high performance fluid mortars, also being built in a resistant assembly capable of supporting and 10 connection to new metal structures on existing pillars These must previously have for the full efficiency of the system a surface conditioned with a certain number of grooves (shear keys) depending on the specific structural requirements.
     fifteen
    The resulting system has important advantages in relation to the purpose it pursues and with respect to other techniques present in the state of the art as listed below:

    A. Easy transport and assembly because it is a set of small format pieces 20 that are moved separately and assembled “in situ”.

    B. The system, as designed, does not require the placement of anchor bolts. This feature is very useful when we are facing supports with low resistance concrete or that the sections have a profusion of reinforcements. The system would also be favorable for when:
    to. the subsequent processes of welding of union with the new structures affect the
    efficacy of chemical anchors (epoxy resins);
    b. the bolts must be located close to the corners of the pillar; 30
    C. The bolts are very close to each other due to the entity of the loads.

    C. For the effectiveness of the system it is not necessary to apply bridges between the old concrete and the mortar.

    D. Part of the efficiency of the transmission of loads to concrete is caused by the fact that it is confined by the system itself.

    From the structural point of view, a specific computer application allows to justify the solution adopted in the terms established in the specific applicable regulations.

    Figure 6.- Shows repetitions of the process to represent that the number of times that may be desired can be repeated depending on the specific structural requirements.

    PREFERRED EMBODIMENT OF THE INVENTION

    By way of exemplary embodiment of the improvements introduced to the patent P201331917 for "System for the cross-sectional confinement of concrete pillars 5 by means of a metal collar", figures 1 to 6 are shown. A pillar is shown in figure 1. that the area of the pillar (1) on which it is desired to act has been identified.

    First, a superficial cut (2) of the area (1) on which it is to be performed is performed. 10 Subsequently, as shown in Figure 2, slots (6) are executed in said area (1). The grooves (6) will act as a cutting key.

     The technician responsible for the repair or structural reinforcement asks the workshop for the inventory of leftover pieces of 'double T' laminated profiles resulting from the 15 wastes collected from executed works.

    With the available profiles, the most suitable ones are chosen according to the structural requirements of the pillar on which the collar is to be placed to serve as a support element for reinforcements and beams. In this regard, it must be taken into account that the system allows the use of parts from different types and sections of profiles "Double T".

    Through a specific computer application, the longitudinal cutting line to be performed on the soul of the selected profiles is calculated. 25

    Cleaning is done by blasting the chosen pieces. That is, four pieces for each module (one in correspondence with each face of the pillar).

    Then, the cross-section of the profiles is carried out according to the dimensions of the pillar and the thickness chosen for the mortar.

    Subsequently execution of a 45 ° bevel at the ends of the soul of each piece.

    Before welding, the assembly will be assembled in the workshop in order to verify the desired geometric accuracy. For this, the subsequent assembly process will be taken into account.
     5
    The first process of placing the collar is preferably carried out after having placed a wooden formwork (3) like the one shown in Figure 3.

    The welding process will begin with a first continuous bead of joint root between plates on their sides in contact (4), as well as in bevel also in contact 10 practiced at the core of both plates, as shown in Figure 4. In successive Contributions will be completed the space that remains between the edges of the pieces in their corners, until forming their complete filling in triangular form. Welding should be done with basic electrodes.
     fifteen
    To conclude, once the set of profiles is mounted around the pillar, a mortar (5) is poured, with controlled retraction and fluid or liquid consistency, preferably pre-dosed. This pouring of mortar may be done at the end of each of the sections or courses of metal plates that make up each module described, or at the end of several courses or, even, at the end of the execution of all 20 of said sections or rows of steel plates .

    Figure 5 shows the placement of a second section of metal collar and Figure 6 shows the placement of subsequent sections of metal collar to show that the process can be repeated as many times as necessary according to the specific requirements of the application.
