Description

[Detailed description of the invention] This invention is based on the joists (
This invention relates to the improvement of joist support fittings for installing joists (or daihiki) on floors such as concrete floors.

As an example of the joist support metal fittings, as shown in FIG. 3,
Bolt insertion holes 4, 4 are provided at both ends corresponding to the standing position of 3'.
It consists of a joist holder 5 having a joist holder 5 and a U-shaped metal fitting 6 fixed to the center of the joist holder 5.
3 through the bolt insertion holes 4, 4', and
, 3' are screwed together to fix the joist receiver 5 at an appropriate height position, and fit the joist 9 inside the U-shaped metal fitting 6, and attach it to the center of the upper end of both side walls. There is one in which the joist 9 is fixed by connecting a pin 10 to a drilled through hole and tightening a nut 11.

However, with the above-mentioned joist support fittings, the joist 9
The height position of the joist 9 can be adjusted by loosening or tightening the upper and lower support nuts 7.8 screwed onto the pair of poles 3 and 3'. However, there were problems in that the assembly work was inefficient and complicated.

In addition, although the weight of the floor is applied to the joists 9, the supporting rigidity of the joist supports 5 supporting the joists 9 is low.

It is an object of the present invention to solve these problems and provide a joist support fitting that is easy to install and has a robust structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on embodiments of a joist support fitting shown in the accompanying drawings.

FIG. 2 shows the joist support fitting of the present invention.

The receiving plate 12 of this joist support metal plate is made of a rectangular metal plate, and both lengthwise ends of this metal plate are bent to form a U-shaped cross section. Nail holes are drilled in it.

A pair of side plates 14 and 14' are provided at both ends of the receiving plate 12.
has been erected.

The side plates 14, 14' are made of metal plate-like bodies, and the lower ends thereof are slightly bent to form a vertical cross-section, and elongated holes 15 extending in the vertical direction are formed in both side walls.
15' is provided to penetrate through the thick part.

Further, anti-slip portions 16 and 16' are formed in the center of the outer surfaces of both side walls and are comprised of a large number of parallel protrusions extending in the lateral direction.

Note that a pair of nail holes for driving nails 13 are bored in the lower end portion.

Also, a U-shaped metal fitting 17 disposed between the side plates 14 and 14'
As shown in FIGS. 3 and 4, the bolt head accommodating portion 18, 1B accommodates the head of the bolt 20, 20' by bending its both side walls in the direction of the side plate 14, 14'. ' are formed, and these bolt head accommodating parts 18, 18'
(Bolt insertion holes 19 and 19' are provided for support holes)
20, 20' are inserted.

The inner peripheral surface of the joist holding portion of the U-shaped fitting 17 is provided with a cushioning material 2 that receives the joist 23 when the joist 23 is held.
4 is inserted.

In addition, a pin 25 is connected to a through hole drilled in the center of the upper end of both side walls of the U-shaped fitting 17, and the joist 23 is fixed by tightening a nut 26 screwed onto the tip of the pin 25 protruding from the side wall. are doing.

Therefore, using the joist support metal fittings according to the above embodiment, the joists 2
3, as shown in Figure 2, install the receiving plate 12 on the floor 27 by driving nails 13 into the nail holes at both ends and fixing the side plates 14 and 14' in an upright position. .

Next, as shown in FIG. 2 and FIG.

21' and nuts 22. After adjusting the joist support height in advance, engage the non-slip parts 16, 16' with washers 21, 21' and tighten nuts 22, 22.
’ to fix the tightening.

Then, as shown in FIG.
It is inserted into the through hole at the center of the upper end of both side walls and tightened with a nut 26 to an appropriate strength.

In addition, with the button above, bolt 20 to U-shaped fitting 17,
The 2σ attachment means is not limited to that shown in the above embodiments, and may be any suitable fixing means such as welding.

Since the joist support fitting of the present invention is constructed as described above, when supporting a joist at an appropriate height above the floor surface, the height position of the joist can be adjusted by simply loosening or tightening a pair of nuts. Therefore, it is possible to save labor when installing a large number of joists on a floor construction surface, and it is possible to significantly improve assembly work efficiency.

In addition, the weight of the floor is applied to the joists, but the U-shaped metal fittings that support this load are connected to the columns with bolts, which increases the support rigidity, which has beneficial effects such as eliminating the displacement of the joist position due to the weight of the floor. play.
