    The invention relates to a method of producing scaffolds, especially ladders. In order to provide a construction solely made of an insulant material, the rails (5) and the rungs (1) of a ladder according to the invention are wholly made of reinforced plastic and are joined to each other by means of a polymeric cold junction method. Thereby a hole (18) is provided on the side of the rail (5) and a suitable amount of a mineral or fiber reinforced monomer mixture (2) is added therein, whereafter the rung (1) is positioned thereto and the resultant whole Is turned upside down, the monomer mixture being polymerized by means of heat, a catalyst and/or an accelerator. So the monomer mixture flows around the junction of the rung (1) and the rail (5), polymerizing therein and forming a tight joint between the rung and the rail.

    专利说明:

    The invention relates to the manufacture of plastic products, in particular, scaffolding, ladders, handrails and steps which are made of hollow pipes or profiles of reinforced plastic.
    The purpose of the invention is to increase the reliability of the design.
    FIG. 1 shows a ladder manufactured according to the invention in FIG. 2, the same, variant; in fig. 3 - the same, another option; in fig. 4 shows a handrail and stair tread connection, in accordance with the invention.
    A ladder made of a hollow tube contains handrails 1 and steps 2. An opening .3 for accommodating step 2 is drilled in handrail 1, which is formed by a hollow pipe made of reinforced plastic and has a circular cross-section (Fig. 1). Stage 2, which is to be glued into the handrail 1, is also made of hollow pipe or reinforced plastic profile, and the end section 4 of the stage, which is inserted into the handrail 1, is made narrower than the rest of the stage 2. As a result, the step 5 of the joint of the narrower end section 4 and the step 2 itself. The cross section of the step 2 does not have any significant effect on the effectiveness of the proposed method, if only the shape of the hole 3 drilled in the handrail 1 corresponds to the shape of the end section 4 steps. So one step contains one or more spikes corresponding to the end section 4 (Fig. 2), which is important especially when the step has the shape of a rectangular parallelogram and is relatively wide, which is why it is preferable to have these spikes on both sides of the tread.
    A portion of a mixture of monomers 6 capable of polymerization, intended for gluing step 2, is inserted inside the handrail 1, in the form of a ring,. the configuration of which corresponds to the configuration of the transverse segmentation of the spike or the spikes of the end section 4 of the step (Fig. 2). The shape of a portion of the mixture of malens 6 is not particularly important, but the annular shape is preferred when necessary

    the amount of glue is as small as possible. A hemispherical or flat pan-shaped form is also possible. However, all of the above mentioned batch forms require that the viscosity of the polymerizable monomer mixture used is sufficient to maintain the cited form for the necessary period when step 2 is inserted in handrail 1.
    If the viscosity of the polymerizable monomer mixture used is so low that the shapes, portions of the type described cannot be used, then one of the ways is possible according to which the cuff 7, made, for example, of paper material, is placed inside the rail by opening 3, drilled therein and a portion of the mixture of monomers 6 is placed in said cuff.
    When the end section 4 of the stage is completely inserted inside the handrail 1, it is brought into contact with the opposite inner surface of the handrail 1. Next, you need to turn the handrail 1 with the steps 2 inserted into it upside down into the position shown in FIG. 4, and then place it in an oven having an appropriate temperature. As a result, the mixture of monomers 6 is polymerized by the action of an accelerator and / or catalyst included in it, and heat, although it is first liquefied to some extent.
    Thus, a large part of the portion of the mixture of monomers 6 is flowing: along the end section 4 of the step 2 down around the joint of the step 2 and the handrail 1, forming an adhesive ring (FIG. 4),
    After the mixture of monomers is polymerized, said ring provides a very tight axial adhesive bond of stage 2 and handrail 1. In addition, one end of stage 2 is attached to the opposite inner surface 1 using the same mixture.
    For additional hardening of the specified glue joint, holes can be made at the end sections of 4 steps 2 in the vicinity of the handrail joint and the step into which the monomer mixture partially flows, resulting in a stronger
    the resulting compound. However, the formation of such holes is not necessary.
    Since steps 2 are formed by hollow plastic pipes or profiles, the mixture of monomers also flows partially into the pipes when the handrail
    1 with steps attached to it
    2 is turned upside down, which improves the connection between the end of the step and the inner surface of the handrail 1. However, you can change the ratio of the mixture of monomers flowing from the inner and outer sides of step 2, doing that part of the end portion 4 of step 2 that is inserted into handrail 1 at least at least partially conical. In this way, it is guaranteed that most of the monomer mixture flows around the connection of the step 2 with the handrail 1.
    To adjust the viscosity of the bonding agent, a mineral or fibrous filler is added to the latter.
    A handrail, which must be connected to the other ends of the steps 2, can be connected in a similar way, which leads to the formation of a ladder.
