Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a receiving bracket with a hanger, which has an extremely small number of parts, has a simple structure, is inexpensive, has excellent strength, and can be installed easily and quickly.

Conventionally, as shown in Fig. 21, the hanger-equipped holder for a board for fastening construction has been constructed in such a way that the bottom of the hanger is at the top of the holder with one or more tiers (trapezoidal mountain shape, gate shape, etc.). There are various types that are fixed with bolts or the like. Each of these brackets is made by bending a band plate and installing reinforcing ribs as necessary.The strength depends on the material, plate thickness, size, plate width, etc. By increasing the thickness, snow accumulation and wind pressure can be reduced.

It was designed and manufactured to withstand vertical and horizontal loads caused by earthquakes, etc. In addition, the hanger has a different fixation point from the neutral line, and a relatively large bending moment is applied to the hanger, so a thick washer or the like is fixed to the bottom of the hanger. Since such hanger brackets are used in large quantities for constructing fastening enclosures such as roofs or walls, they may be simply made thicker so that they can withstand strength, or they may be made with washers. In the case of a receiving bracket with a hanger, the material cost increases, the press processing machine becomes large, and the construction cost of the clamping enclosure as a whole becomes high.

For this reason, the applicant has already developed and researched a method that can strengthen even a thin metal material by providing bent parts, bulging ribs, etc. before and after the shank part of the receiving metal fitting. Therefore, there is a need for something that has sufficient strength and is cheaper.

Therefore, the present invention forms a rising part as an example of the mounting bottom,
A top part is formed from the upper end, and a receiving bracket is integrally bent with a relatively thick band of metal, and the lower part of the hanger is superimposed and fixed to the rising part, or it is attached. An example of a bottom part is to form a rising part, form a top part from the upper end, integrally bend a receiving bracket with a relatively thin band of metal, and place the top part on the rising part except for the top part. A vertical rib is provided, and a reinforcing rib is formed at at least one end in the width direction of the mounting bottom, rising part, and top, and the lower part of the hanger is superimposed and fixed to the rising part, or a part of the mounting bottom is fixed. Form a rising part on the side, form the top from # on the nucleus,
These are integrally bent to form a receiving bracket using a band plate made of a relatively thick metal material, and the receiving washer is made of a relatively thick metal material and has an inverted cross section consisting of an upper surface part and a hanging part. By polymerizing and fixing the lower part of the hanger to the hanging part, and then clamping the lower part of the hanger to the rising part of the receiving washer and fixing it with bolts, etc., the amount of parts can be dramatically increased. It is easy to process, can be provided at an extremely low cost, has excellent strength, and can be installed easily and quickly, thus solving the above-mentioned drawbacks.

The structure will be explained with reference to the drawings.

Reference numeral 1 denotes a mounting bottom part, and a rising part 2 is formed on the negative side (the left side in FIGS. 2, 3, etc.) of the mounting bottom part. 3 is bent. The top part 3 is bent to the side opposite to the mounting bottom part 1 side (see Figures 1 to 3, etc.), or is bent to the mounting bottom part 1 side (see Figure 4), and the mounting bottom l
When viewed from the side, the receiving metal fitting consisting of the rising portion 2 and the top portion 3 is configured in an O-shape or a U-shape. A through hole 4 may be bored approximately in the center of the mounting bottom 1.

Further, the shape of the locking portion 7b is not limited to these, and it is sufficient if there is a piece that can be locked. The vertical portion 7a of the hanger 7 is superimposed and fixed onto the upper portion of the rising portion 2 of the receiving metal fitting. This fixing is often done at the time of construction, but it may also be done in advance. In addition, as for its fixing structure, a screw hole is bored in the rising part 2 made of a relatively thick metal plate of an appropriate thickness (the second
(see Figures 3 and 3), and screw them in with bolts 8.

Such a receiving metal fitting provided with a hanger 7 is the receiving metal fitting with a hanging rod of the first embodiment (see FIG. 1, FIG. 2, etc.). Also,
Another fixing configuration is to fix the nut 9 to the rising portion 2 made of a relatively thin metal material (see Fig. 7), or to fix the washer 10 with a screw hole (see Fig. 11). (see figure), and screw it in with bolt 8. A product in which a hanger 7 is provided on such a receiving metal fitting is a receiving metal fitting with a hanging rod of the second embodiment (FIG. 6).

(See Figures 7 and 11). Said 1st. In the receiving bracket with a hanger according to the second embodiment, a washer 11 may be fixed in advance to the vertical portion 7a of the hanger 7 (see Figs. 3 to 7).
(see figure). Reference numeral 12 denotes a receiving washer that hangs down from one end of the upper surface portion 12a (approximately horizontal or gently sloped).

The receiving washer ``12'' may also be made of a band plate made of a relatively thick metal material with an appropriate thickness (see Fig. 12, Fig. 13, etc.), or a band plate made of a relatively thin metal material. A reinforcing rib 13 is bent at at least one end (both ends in the drawing) in the width direction (FIG. 14).

(See Figure 15, etc.) And the hanging portion 12b of the receiving washer 12
is superimposed and fixed to the upper part of the rising portion 2 of the receiving metal fitting. This fixing is often done at the time of construction, but it may also be done in advance. In addition, as for its fixing structure, a screw hole is bored in the rising part 2 made of a relatively thick metal plate of an appropriate thickness (see Fig. 13), and it is screwed with a bolt 8. do.

The third embodiment of the hanger-equipped bracket includes a hanger 7 attached to such a bracket via a relatively thick metal receiver washer 12 (see Figs. 12, 13, etc.). ) 3 In addition, as another fixing structure, the rising part 2 made of a relatively thin metal material
A nut 9 or a washer 10 having a screw hole is fixed thereto, and the bolt 8 is screwed into the nut 9. A receiving metal fitting with a hanger according to the fourth embodiment is such a receiving metal fitting with a hanger 7 provided through a relatively thin receiving washer 12 (see FIG. 14, FIG. 15, etc.). After being fixed in this manner, the top portion 3 and the upper surface portion 12a are configured to be at approximately the same height (see FIGS. 12 to 15). In the figure, numeral 14 is a structural material such as a main building or a frame, and numeral 15 is a board for fastening construction such as roofing material or wall material.

Next, the effects will be explained.

First, place the bracket on the structural member 14, and attach the mounting bottom 1.
are fixed with bolts or welding, and then fastened to the construction board 1.
5 on the top 3 of the receiving metal fitting, and lock the locking part 7b of the hanger 7 to the locking part of the end.
The vertical portion 7a of the vertical portion 7a is fixed to the rising portion 2 of the receiving metal fitting with bolts 8 or the like, and these steps are repeated in order to construct the fastened outer enclosure.

In some cases, the hanger 7 may be fixed to the bracket in advance,
This may be used as is, or a large number of brackets may be fixed to the structural member 14 at regular intervals, and then the fastening construction board 15 may be placed on the brackets. In some cases, the hanger 7 is locked and bolted to perform the tightening work.

In this way, in the invention of claim 1, a rising part 2 is formed on one side of the mounting bottom part 1, a top part 3 is formed from the upper end, and these parts are connected to a relatively thick strip of metal. By integrally bending the bracket and fixing the lower part of the hanger 7 to the rising part 2, firstly, the number of parts is small, making the structure simple and inexpensive, and secondly, it is strong. Thirdly, it has many advantages such as being extremely easy and quick to install.

To explain the effects in detail, first, the conventional receiving metal fitting has the 21st
As shown in the figure, even if there is only one mountain, the yamabushi part and the bottom part are integrally formed, but compared to this, in the receiving metal fitting of the present invention, it is approximately O-shaped or U-shaped when viewed from the side, and a hanger 7 is provided. Even so, materials such as the bottom and bottom washer can be saved, and the entire hanging bracket can be manufactured using about half the material.
The unit cost of materials is halved, allowing for significant resource savings. In addition, despite such a simple configuration,
- When attached to the clamping part of the hanging plate 15, the compressive load (snow accumulation, etc.) of the vertical load (snow accumulation, wind pressure load, etc.) applied to the suspension bracket is received by the top part 3, and the load is transferred to the rising part 2. However, sufficient compressive strength can be obtained with only the rising portion 2 made of relatively thick material, and the tensile load (wind pressure load, etc.) is applied to the rising portion 2 to which the hanger 7 is fixed. ,
Unlike the conventional case where a bending moment is applied due to a displacement between the point where the hanger is fixed and the neutral line of the hanger, the bending moment value due to the tensile load of the hanger 7 can be reduced to approximately zero. The tensile strength of the rising portion 2 can be made to be sufficiently durable, and an extremely strong receiving bracket with a hanger can be provided. As described above, the great advantage of the present invention is that it can be made superior in strength in terms of material mechanics, and the amount of material can be significantly reduced. Furthermore, the fact that the press machine can be constructed using less material also makes the press machine more compact, and as a result, an extremely inexpensive receiving bracket with a hanger can be manufactured. In addition, when installing the hanging bracket to the structural material 14, etc., it is only necessary to fix the joints on the mounting bottom 1 with bolts or welding, compared to the conventional method which requires mounting at at least two locations. As a result, the construction efficiency is doubled, and the construction cost of the fastening enclosure such as the roof or wall can be significantly reduced.

Next, in the invention as claimed in claim 2, a rising part 2 is formed on one side of the mounting bottom part 1, a top part 3 is formed from the upper end, and these parts are connected to a relatively thin strip of metal. A receiving metal fitting is integrally bent and formed, and a vertical rib 5 is provided on the rising part 2 of the mounting part except for the upper part, and a reinforcing rib 6 is formed on at least one end in the width direction of the mounting bottom part 1, rising part 2, and top part 3, By polymerizing and fixing the lower part of the hanger 8 to the rising part 2, the first
Even relatively thin materials can be made to have much superior compressive and tensile strength, similar to relatively thick metal materials, and this effect has been shown to achieve ground-breaking values through experiments. was completed. Secondly, the number of components can be further reduced than that of the receiving bracket with a hanger according to the first aspect of the invention, and the cost can be further reduced.

Other functions and effects are substantially the same as those of the first aspect of the invention.

Further, in the invention of claim 3, a rising portion 2 is formed as an example of the mounting bottom portion 1, and a peak g11 is formed from the upper end.
3 is formed, and a receiving bracket is integrally formed by bending a relatively thick band plate made of metal, and the upper surface part 12a and the hanging part 1 are formed.
The lower part of the hanger 7 is superimposed and fixed to the hanging part 12b of a relatively thick metal receiving washer 12 which has an inverted cross-section and consists of 2b, and the hanging part 12b of the receiving washer 12 is connected to the rising part 2. By clamping the lower part of the hanger 7 and fixing it with bolts 8, etc., the compressive load (snow accumulation, etc.) of the vertical load (snow accumulation, wind pressure load, etc.) is first transferred to the top portion 3 and the upper surface portion 12b. As a result, the construction board 15 can be supported in an extremely stable structure, and its compressive and tensile strengths can be significantly strengthened. It can exhibit the same effect as the invention of item 1.

In particular, in the present invention, the receiving washer 12 is made of a relatively thick metal material and has an inverted cross-section and is composed of an upper surface portion 12a and a hanging portion 12b, and the hanging portion 12b is attached to the rising portion 2 with a hanger. By clamping the lower part of the hanger 7 and fixing it with bolts 8, etc., the upper surface part 113-2a can be used as a support part, and the hanging part 12b serves as a reinforcing washer for the lower part of the hanger 7. , tensile load (
It can be made into a receiving bracket with a hanger that is extremely strong against wind pressure, etc.
