Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting bracket for building materials, such as a sash bar, for attaching building materials to the edge of a wall.

When the walls of a building are constructed of, for example, aerated concrete and are provided with openings such as windows, doorways, etc., the periphery of the large opening needs to be reinforced with steel having an L-shaped cross section. For this reason, when installing construction materials such as satsushi bars on the edge of the wall, conventionally,
At the construction site, holes were drilled into the L-shaped steel to form screw holes for attaching the sassive bars. However, the problem with such drilling work is that the workability is extremely poor because the L-shaped steel is hard.

Therefore, an object of the present invention is to provide a mounting bracket for building materials that can be easily fixed to the edge of a wall by simply driving it in, and that can be easily attached to the edge of the wall. It is in.

Below, Figures 1 to 4 are related to the first embodiment of the present invention.
This will be explained with reference to the figures. 1 is the wall of the building,
It is constructed from aerated concrete panels. Reference numeral 2 denotes a steel frame with an L-shaped cross section, which is fixed along the periphery of an opening 3 formed in a wall 1 to constitute, for example, an entrance/exit of a building, and one side 2a of it is fixed as the opening 3. 3, the inner surface is attached, and the other side 2b is attached to the outdoor side wall surface. The edges of the opening 3 of the wall 1 are chamfered D and E. 4
is a plurality of mounting brackets (only one is shown) driven between the wall 1 and the L-shaped steel 2;
It has an elongated flat plate shape with a substantially U-shaped mounting piece 5 bent at the end on the opposite side (right side in the figure) protruding from between it and the shaped steel 2, and the mounting piece 5 is provided with a screw hole. 6, and the front part on the driving side is driven into the L-shaped steel 2 in a bent state in a substantially L-shape along both sides 2a and 2b. Such mounting bracket 4
Before driving, as shown in Figures 2 and 3, it extends straight from the opposite driving end to the driving end, and the overall length A is longer than the length B of one side 2a of the L-beam 2. It is forming a large size. The leading end of the mounting bracket 4 on the driving side is formed into a wedge shape, and a long hole 7 corresponding to a notch is formed in the leading end of the driving side so that the leading end can be easily bent. Reference numeral 8 denotes a sassive bar as a construction material that is attached along the inner peripheral edge of the opening 3 via a mounting bracket 4, and is provided with mounting holes 9 intermittently along the longitudinal direction. It is fixed by screwing a screw 10 inserted into the hole 9 into the screw hole 6 of the mounting fitting 4. Reference numeral 11 indicates an exterior mortar coated on the outdoor side wall surface of the wall body 1, and 12 indicates a caulking material filled between the sash bar 8 and the exterior mortar 11.

A method for attaching the sash bar 8 in the above configuration will now be described. First, the tip of the mounting bracket 4 on the driving side is placed between the joint surface of the side 2a of the L-shaped steel 2 and the wall 1, and the end on the side of the mounting piece 5 is hammered with, for example, a hammer 13 (Fig. 4). reference). Then, the tip of the mounting bracket 4 is driven between the wall 1 and the L-shaped steel 2, and gradually penetrates deeply to the left. and,
When the tip of the mounting bracket 4 comes into contact with the arc-shaped inner surface of the bent portion 2c of the L-shaped steel 2, the front end of the mounting bracket 4 is bent because the elongated hole 7 is formed in the front part and there is little resistance to bending. is bent along the bending portion 2c, and as a result, the tip end facing upward enters between the other side 2b of the L-beam 2 and the wall 1, and when the driving is completed, the first As shown in the figure, the front part is bent into a substantially L-shape. Note that the edge of the wall 1 is removed in a chamfered manner, and the L-shaped steel is removed in a chamfered manner, creating a gap between the inner surface of the bent portion 2c of the L-shaped steel 2, and Bent part 2
cThe inner surface is generally curved in an arcuate concave shape, so
The front part of the mounting bracket 4 can be bent more easily. After fixing the mounting bracket 4 in this manner, insert the screw 10 into the mounting hole 9 of the sassive bar 8 and screw it into the screw hole 6 of the mounting piece 5 of the mounting bracket 4, completing the installation of the sassive bar 8. do. In this installation state, the front part of the mounting bracket 4 on the driving side is bent into a substantially L-shape and also bites between the other side 2b of the L-shaped steel 2 and the wall 1, so the mounting bracket 4 Even if a force in the pulling direction is applied, there is no risk of the sash bar 8 coming out, and the sash bar 8 can be firmly fixed to the inner circumferential edge of the opening 3.

5 and 6 show a second embodiment of the present invention, and the difference from the first embodiment is that the mounting bracket 14
A mounting piece part 1 extending downward at the end on the opposite side of the drive.
5, and in the third embodiment shown in FIGS. 7 and 8, a mounting piece 17 is formed at the end of the mounting bracket 16 on the side opposite to the driving direction and extends upward. Furthermore, FIGS. 9 and 10 show a fourth embodiment, which differs from the first embodiment in that a bolt 19 is extended from the opposite end of the mounting bracket 18 to the bolt part 19. is inserted into the mounting hole 9 of the sassive bar 9, and the sassive bar 9 is fixed with a nut 20. Further, the notch is not limited to the long hole 7 as shown in the first to fourth embodiments, but may be formed in the front part of the mounting bracket 4 as in the fifth embodiment shown in FIG. It may be composed of a large number of groups of small holes 21, or it may be composed of several slits 22 that are open at the distal end of the mounting bracket 4, as in the sixth embodiment shown in FIG.

As described above, the present invention can be reliably fixed by simply driving the frame between the wall and the L-shaped cross-section frame fixed to the edge of the wall. It is possible to provide a construction material that can be easily attached to the body edge.
