Description

[Detailed description of the invention] (Field of industrial application) The present invention is an inclined crosspiece type in which a plurality of inclined crosspieces, each inclined in opposite directions, are assembled in an arrow pattern between the upper and lower horizontal crosspieces. The present invention relates to a lattice body, and more specifically relates to a connection structure between upper and lower horizontal bars and each slanted bar in such a slanted bar type lattice body.

(Prior art) In this type of conventional slanted bar-type lattice body, when assembling each slanted bar (a right-down slanted bar and a right-up slanted bar) which are inclined in opposite left and right directions to the upper and lower horizontal bars, In general, the ends of each inclined crosspiece were fixed to the horizontal crosspiece by screws or welding, but these fixing methods (screws, welding, etc.)
Welding, etc.) has problems such as poor workability, increased number of parts (in the case of screw fastening), and the need for welding equipment, which increases assembly costs.

By the way, the present applicant has proposed that in a lattice body in which a plurality of vertical bars are interposed between the upper and lower horizontal bars at a predetermined interval in the left-right direction, the ends of each of the vertical bars are fixed to the upper and lower horizontal bars. A method has already been proposed in which the ends of the vertical beams are connected to the horizontal beams by concave-convex fitting and caulking without using screws, welding, or other means (for example, in practical applications). Showa 60-
Publication No. 89369). As shown in FIG. 15, the lattice body of this previously applied application has ends 104a, 104b of vertical bars 104, 104, . By forming kerf grooves 113, 113, . The longitudinal bar end 104 is positioned immovably in the direction
A and 104b are partially deformed by pressing and are caulked to the protrusion 112, thereby preventing the vertical bar 104 from separating from the horizontal bars 101 and 102. There is. However, in a lattice body in which a plurality of vertical bars 104, 104, etc. are arranged at a predetermined interval between the upper and lower horizontal bars 101, 102, as described above, Although it is possible to relatively easily connect the horizontal beam and the vertical beam by fitting the end portions of the vertical beam into concave and convex portions and crimping them together, each sloped beam that slopes in different directions between the upper and lower horizontal beams is In the inclined crosspiece type lattice body, which is assembled in an arrow pattern,
The above-mentioned lattice connection structure (concave-convex fitting between the end of the vertical bar and the groove, and caulking connection between the end of the vertical bar and the protrusion)
cannot be adopted as is. That is, as shown in FIG. 16, the inclined crosspiece type lattice body has an inclined cross-section assembly 203 formed by assembling right downward slope crosspieces 204 and right upward slope crosspieces 205 in an arrow pattern, and the upper and lower horizontal crosspieces 20.
1,202. Inclined bar 20
The kerf 213 for inserting the end of 4,205 is cut parallel to the inclination direction of the slanted crosspiece (downward sloped crosspiece to the right or upward sloped rightward) to be inserted into the kerf, and the above-mentioned sloped arrow assembly When assembling 203 between the upper and lower horizontal bars 201 and 202, align the end of the sloping bar (right downward sloping bar or right upward sloping bar) with respect to the kerf in the direction of inclination of the slanted bar and kerf. This is done by entering the At this time, the ends 204a and 204b of the inclined crosspieces (for example, the right downwardly inclined crosspiece 204) that are inclined toward the approach direction can be moved in the direction of the solid arrow X and inserted into the corresponding kerfs 213 and 213. However, an inclined bar that is inclined in the opposite direction (for example, a right-up inclined bar 20)
The ends 205a and 205b of 5) move as shown by the dotted arrow Y and collide with the upper surface (in the case of the lower horizontal beam side) or the lower surface (in the case of the upper horizontal beam side) of the protrusion portion 212, and the The inclined crosspiece (right upward sloped crosspiece 205) cannot be fitted into the kerf 213, and therefore the inclined crosspiece assembly 203 cannot be assembled between the upper horizontal crosspiece and the lower horizontal crosspiece.

(Purpose of the invention) In view of the above-mentioned problems of the conventional lattice connection structure, the present invention provides an inclined crosspiece type lattice body in which a right-downward sloped crosspiece and a right-upward sloped crosspiece are assembled in an arrow pattern. The purpose of the present invention is to propose a connection structure that simplifies the process and allows easy assembly of the upper and lower horizontal bars and each inclined bar.

(Means for Achieving the Purpose) The present invention has a plurality of right-down sloping bars that are parallel to each other and tilt in the right-down direction between the upper horizontal bar and the lower horizontal bar. In a slanted bar-type lattice body formed by assembling a plurality of sloping right-up slant lines to each other in an arrow pattern, each of the right-down slant lines is provided on mutually opposing surfaces of the upper lateral bar and the lower lateral bar. and protrusions are formed for fitting the upper and lower ends of each of the right-up sloping bars, and each of the right-down sloping bars or each right-up sloping bar in each of the ridges is formed. A kerf for positioning the end of each of the inclined bars is formed at a position where the end of each of the inclined bars is arranged, and is inclined parallel to the direction of inclination of the inclined bar. The right-up sloping bars are connected to each other so as not to be displaced in the lateral direction, and each of the right-down sloping bars and each right-up sloping bar slanting to either the left or right side at the upper end side and the bottom end side of each right-up sloping bar is The upper end and/or lower end of each inclined bar is slidably fitted to the protrusion in the longitudinal direction of the horizontal bar, while the upper end and/or lower end of each inclined bar is inclined toward the other side. is fitted into the kerf in a non-slidable manner in the longitudinal direction of the horizontal crosspiece.

(Function) The connecting structure of the inclined crosspiece type lattice body of the present invention is that each downwardly inclined rightwardly inclined crosspiece and each upwardly inclined rightwardly inclined crosspiece are connected to each other in a manner that cannot be displaced in the lateral direction, and each downwardly inclined rightwardly inclined crosspiece and each rightwardly upwardly inclined The upper end and/or lower end of each inclined bar that slopes to either the left or right side on the upper and lower end sides of the up-sloping bar is slidably fitted to the protrusion of the horizontal bar in the longitudinal direction of the horizontal bar. The upper and/or lower ends of each of the slanted bars, which are tilted toward the other side, are fitted into the grooves formed in the protrusions in a non-slidable manner in the longitudinal direction of the lateral bars. When interposing an inclined arrow assembly consisting of a right-down inclined beam and a right-up inclined beam assembled in an arrow pattern between horizontal beams, the end of each inclined beam that slopes to one side is the upper horizontal beam or the lower horizontal beam. When fitted into the kerf formed in the ridge, the end of each inclined bar that slopes to the other side does not abut the ridge, and the slope of the kerf fitting side is prevented. It becomes possible to fit the crosspiece end portion and another inclined crosspiece end portion to the protruding portion at the same time.
