Description

[Detailed Description of the Invention] The present invention relates to a joist support metal fitting for installing a joist used for receiving floorboards of a building on a concrete floor surface.

As a conventional joist support metal fitting, as shown in FIG.
A pair of bolts 3 erected at both ends on the longitudinal center line,
3', a joist holder 5 having bolt insertion holes 4 at both ends corresponding to the upright position of this bolt 3° 3', and this joist holder 5.
A U-shaped metal fitting 6 is fixed to the center of the bolt 3.3' by inserting the bolt insertion hole 4 into the bolt 3.
Joist support 5 with nut 7.8 screwed onto t3'
is fixed at an appropriate height position, and the U academic member 6
The joist 9 is fixed by fitting the joist 9 into the inside of the joist 9, connecting the pin 10 to a through hole drilled in the center of the upper end of both side walls, and tightening the nut 11 screwed onto the tip of the pin 10 protruding from the side wall. There was something that made me do it.

However, with the above-mentioned joist support fittings, the joist 9
In order to fit into the 0-shaped bracket 6, the pin 10 must be removed in advance.Then, the joist 9 is inserted into the 0-shaped bracket 6, and the pin 10 is inserted into the through hole of the U-shaped bracket 6. Since they are connected and tightened with nuts 11, there are problems in that installing a large number of supports requires a great deal of labor and time.

The present invention was developed in view of the above points, and is a joist support in which the joists are held between the bolts by upper and lower joist supports that are screwed onto bolts installed at both ends of the foundation board. The purpose is to provide metal fittings.

Hereinafter, the present invention will be described in detail based on embodiments of the joist support fitting shown in the accompanying drawings.

As shown in FIGS. 2 and 3, the base plate 21 of the joist support metal plate is made of a rectangular metal plate, and there are holes at both longitudinal ends of this metal plate for driving concrete nails 22. A pair of nail holes are drilled in each.

Also, a pair of protrusions 23 are provided near both ends of the longitudinal center line of the base plate 21 on the inside of this nail hole, and a bolt insertion hole 24 is provided in each flat part of the protrusion 23. Bolts 25 and 25' are erected and fixed with fixing nuts 26.

In addition, the pole 25.25' erected on the base plate 21
The joist receiver 28 is fixed to and for holding the joist 27 between the bolts 25 and 25' is formed so that the joist 27 is held from above and below by a joist receiving upper plate 28a and a joist receiving lower plate 28b. Together with this joist receiving upper plate 28a and joist receiving lower plate 28b
Bolt insertion holes 29 and 30, through which the bolts 25 and 25' are inserted, are provided at both ends of the upper and lower joist receiving plates 28a and 28b, respectively.
They are provided at both ends in the longitudinal direction.

As shown in FIG. 1, cushioning materials 31 are attached to the inner peripheral surfaces of the joist holding portions of the upper and lower joist receiving plates 28 at 28 b, respectively.

This cushion material 31 supports the joist 27 on the joist receiving upper and lower plates 28a.
.

This is to prevent the surface of the joist 27 from being damaged when it is held by the joists 28b.

In addition, in FIGS. 3 and 4, the reference numeral 32 indicates the joist receiving plate 2.
8b shows an emboss formed in a concave shape, and this emboss 32 prevents deformation of the joist receiver 28 when supporting the joist 27.

Therefore, using the joist support metal fittings according to the above embodiment, the joists 2
7, as shown in FIG.
．． 25' is erected and the foundation plate 21 is installed on the concrete floor surface 33.
For installation, drive concrete nails 22 into the nail holes at both ends and fix with bolts 25 and 25' standing upright.

Next, the nuts 34 for mounting and fixing the joist receiving plate 28b are screwed onto these bolts 25 and 25', respectively, and the joist receiving plate 28b is further fitted to adjust the joist supporting height in advance.

Next, the joist 27 is inserted into the joist receiving lower plate 28b, and then the joist receiving upper plate 28a is inserted into the bolts 25, 25', and the joist 27 is inserted into the joist receiving plate 28b.
Correct the joist support height so that the joists 7 are horizontal, then screw in the nuts 35 that are fixed to the bolts 25 and 25', respectively, and clamp and fix the joist support upper and lower plates 28a and 28b with the nuts 34 and 35. .

Since the joist support fitting of the present invention is constructed as described above, when supporting the joist at an appropriate height, fixing fittings such as U-shaped fittings and pins are no longer necessary, thus reducing the number of parts. In addition to simplifying the work of fixing the joists, it is possible to greatly reduce the labor and time required to support the joists, as well as reduce costs. It has a beneficial effect.
