Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to an assembly structure of a lattice body used for housing building materials and the like.

[Conventional technology]

Conventionally, in order to assemble this type of lattice without wobbling, as shown in FIG. Either join them together, or as shown in Fig. 13, a locking piece e is provided protruding from the center of a notch b formed in the horizontal lattice bar a, and the lattice bar c is fitted into the notch b. A locking piece e is inserted into a locking hole f protruding from c, and the tip is bent and locked to join the two together.Furthermore, in order to enhance the rattling prevention effect, cushioning parts are also used at these joints. was. Furthermore, as a prior art, Japanese Utility Model Application No. 53-23148 discloses that after a tubular support rod is inserted into a through hole of a hollow crosspiece, the part of the support rod that is inserted into the hollow inside of the crosspiece is By expanding outward with a special tool with needle-like protrusions and a punch, the crosspiece and support rod are fixed.
The expansion part of the support rod prevents it from slipping out in the longitudinal direction.
Japanese Utility Model Application Publication No. 57-204384 discloses a technique for preventing slippage in the projected direction using a through hole, in which one muntin is fitted into a notch in the other muntin, and the upper end of one muntin is fitted into a notch in the other muntin. Techniques have been disclosed for tightly fitting and fixing both muntins by strongly pressing the wedge portions bulging out on both sides against the notch portions, causing the wedge portions to be plastically deformed and brought into pressure contact with the notch portions.

[Problem that the idea aims to solve]

However, these conventional assembly structures that take into account rattling prevention have the disadvantage of requiring a large number of work steps and high costs due to parts, screws, and installation.
Furthermore, since a gap inevitably occurs between the notch of one lattice bar and the other lattice bar fitted therein, the appearance is unsightly and the product value is lowered. In addition, the former prior art is intended to prevent the support rod from slipping out in the longitudinal direction at the inflatable part, and requires a special expansion process that is complicated and inefficient during assembly work. In the case of the latter, the expansion state cannot be confirmed from the outside, and it is difficult to securely inflate and fix it, which may cause looseness. Since it acts and supports at one point on the part, the fitting force is extremely weak.Furthermore, the wedge part bulges out in a tapered shape in the direction of the projection, so one muntin is more easily attached than the notch in the other muntin. There is a risk that it will slip out in the direction of the forecast. Therefore, this invention was developed in view of the problems of the various technologies mentioned above, and it is a solution that utilizes the elasticity of the lattice crosspieces, and can be joined without using any special parts with a strong, loose, and beautiful appearance. The object of the present invention is to obtain a lattice assembly structure that is easy to assemble, inexpensive, and has high commercial value.

[Means to solve the problem]

As a means to achieve this, this invention provides a lattice body that is assembled by fitting the other lattice bar into the notch for fitting the lattice bar provided in one lattice bar, and the other lattice bar is constructed from a hollow member. The side wall surface of the other lattice crosspiece that abuts the opposing parallel side edges of the notch is bulged out in an arc shape over the entire surface in the viewing direction, and the apex of the bulge is located at the center of the side wall surface in the viewing direction. The maximum width between the bulging portions is formed to be slightly larger than the dimension between opposing parallel side edges of the notch, and the entire side wall surface of the bulging portion of the other lattice beam fitted into the notch of one lattice beam in the expected direction. Both lattice beams are joined by elastic pressure welding to opposing parallel side edges.
