Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a structure for attaching a grid to an opening in a building.

[Background technology]

Conventionally, installing a grid over an opening in a building required multiple members, which not only took time to assemble, but also required a large number of workers, resulting in poor installation workability. It was hot.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and its purpose is to reduce the number of parts required for installing a grid, which can be installed accurately and easily, and to create an opening in a building that is easy to install. The object of the present invention is to provide a structure for attaching a surface grid to a section.

[Disclosure of the invention] The structure for attaching a surface lattice to an opening in a building according to the present invention is to attach an upper frame 4 to an opening 3 formed in an outer wall 2 of a building 1.
A window frame 6 provided with a locking rail groove 5 is fitted to the front surface of the window frame 6, and a reinforcing rib 17 is provided at the corner portion, consisting of a horizontal piece 8a and a vertical piece 8b, at the upper end of the back surface of the surface lattice 7. An inverted L-shaped locking piece 8 is projected, and the vertical piece 8b of the locking piece 8 of the surface lattice 7 is inserted and locked into the locking rail groove 5 of the window frame 6. The above objectives have been achieved. Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. A window frame 6 is fitted into an opening 3 formed in an outer wall 2 of a building 1. Sliding grooves 10 for sliding doors (not shown) are provided on the inner surfaces of the upper frame 4 and lower frame 9 of the window frame 6.
An engagement groove 11 having a substantially C-shaped cross section and projecting upward is provided in the front part of the upper frame 4 over the entire length, and the lower part of this engagement groove 11 has a substantially C-shaped cross section. The shaped portion serves as a locking rail groove 5.
In this embodiment, a lower engagement groove 18 having a substantially C-shaped cross section and projecting downward is also provided on the front surface of the lower frame 9 of the window frame 6 over its entire length. Reference numeral 7 denotes a surface lattice, which is formed by stretching a mesh body 13 over a frame-shaped surface lattice main body 12. 8 is an inverted L-shaped locking piece;
Mounting piece 1 protruding upward from the tip of the horizontal piece 8a
4 are fixed with screws 16 on both sides of the back surface of the upper frame portion 15 of the screen grid main body 12, and protrude rearwardly from the back surface of the screen grid 7. This locking piece 8 includes a horizontal piece 8a and a vertical piece 8.
A reinforcing rib 17 is provided by concavely bending a substantially central portion of the corner portion with b. Therefore, even if the locking piece 8 has a thickness of about 2 mm, sufficient allowable yield strength can be obtained. On both sides of the back surface of the lower frame part 19 of the screen grid body 12, the locking pieces 8 are fixed upside down with screws 16 using the mounting pieces 14, so that the lower locking pieces 20 are made to protrude rearward. The vertical piece 8b of the locking piece 8 of the surface grid 7 is inserted into the locking rail groove 5, and the lower vertical piece 20b of the lower locking piece 20 is inserted into the lower engagement groove 18. The vertical piece 8b of the locking piece 8 is slid laterally along the locking rail groove 5 and its position is adjusted, and the vertical piece 8b of the locking piece 8 is screwed to the front side piece 5a of the locking rail groove 5, and the lower locking piece 20 The lower vertical piece 20b is screwed into the lower engagement groove 18, and the surface lattice 7 is attached and fixed to the window frame 6.

[Effect of the idea]

In the case of this invention, a window frame with a locking rail groove provided in the front part of the upper frame is fitted into an opening formed in the outer wall of the building, and a horizontal piece and a vertical piece are attached to the upper end of the back side of the face lattice. An inverted L-shaped locking piece with a reinforcing rib at the corner is made to protrude, and the vertical piece of the locking piece of the surface lattice is inserted and locked into the locking rail groove of the window frame. Therefore, not only the number of parts required for installing the surface grid is reduced, but also vertical positioning can be performed by inserting the locking pieces into the locking rail grooves during installation. The lateral position can be adjusted by sliding the stop piece laterally along the locking rail groove, so it can be installed accurately and easily by one worker. , has excellent workability. Furthermore, since the locking piece is provided with reinforcing ribs, even if the locking piece is made of a thin plate, sufficient allowable yield strength can be obtained, resulting in a reduction in material costs.
