Description

[Detailed description of the invention] The present invention relates to a fixing fitting for joining a square piece such as a square pipe to a metal form, in which at least two holes are provided in a plate such as an edge piece of the metal form. This invention relates to improvements in construction fixtures used to pull together and connect other rod-shaped bodies or blocks, such as square pipes, to a location where they are placed.

Conventionally, this type of architectural fixing metal fittings have been proposed, for example, as in Utility Model Publication No. 52-7700.
In this conventional example, the distance from the hanging part of the main body to the wedge accommodating part is constant, so that one square timber is interposed between the hanging part and the wedge accommodating part, and the other is that two square timbers are interposed between the hanging part and the wedge accommodating part. This had to be constructed separately, which resulted in a large number of types of fixing fittings, which was very inconvenient.

The present invention was made in view of the above-mentioned drawbacks of the conventional rod-shaped rod, and the vicinity of the top of the bar fastening rod, which is made by bending the rod-shaped body into a substantially square shape, is made into a somewhat obtuse angle, and the top part has a thickness of a wedge. bent horizontally in a crank shape by an amount close to , and bent both tips of the fastening rod laterally in opposite directions and upward from a right angle to form a hanging part, and the tops on both sides of the fastening rod and The present invention relates to a construction fixing fitting comprising a one-shaped wedge holding part protruding horizontally between the hanging parts, and a wedge insertion part provided between the wedge holding part and the fastening rod. .

Below, the embodiments of the present invention will be explained with reference to the drawings.
As shown in FIGS. 5 to 5, the bar fixing rod 1, which is formed by bending a rod-shaped body into a substantially square shape, has a somewhat obtuse angle near the top 2 and 3, and the top 4 is the flesh of a wedge 13. It is bent laterally in a crank shape by an amount close to the thickness, and both ends of the fastening rod 1 are bent laterally in opposite directions at a somewhat acute angle upwards from the right angle, for example, on the edge piece 20 of the metal form 19. Drilled mounting hole 2
Hanging parts 5 and 6 that fit into 1 are constructed.

The hanging parts 5 and 6 are located on the side of the fastening rod 1 where the crank-shaped part of the top part 4 is located, and on both sides of the fastening rod 1 there is a horizontally shaped one on the side facing the hanging parts 5 and 6. Holding part 7 of wedge 13
, 8 and the fastening rod 1, wedge insertion portions 9, 10, 11 .
The present invention is implemented by configuring a construction fixture that is connected by welding or the like so as to provide 12.

In the figure, reference numeral 14 denotes a through hole drilled in the holding parts 7 and 8, which is used when the wedge 13 and the fixing metal fitting of the present invention are connected by a string or chain.

The present invention is constructed as described above, and when the wedge 13 is inserted into the upper wedge insertion parts 9 and 10 and the square members 22 and 23 are tightened, the wedge 13 is inserted between the holding parts 7 and 8 and the fastening rod 1. The wedge 13 is held in the wedge insertion parts 9 and 10 between the wedges and supported in a stable state, and the pressure applied to the wedge 13 is received under the top part 4, so the fastening must be performed with a very large force. It is something that can be done.

When the wedge 13 is inserted into the wedge insertion portions 9 and 10, the two square pieces 22 and 23 can be fastened together in a stacked state.

Furthermore, in the present invention, when the wedge 13 is inserted into the lower wedge insertion part 11.12 that is away from the top, the pressure applied to the lower wedge 13 is received by the holding parts 7 and 8. This can also be concluded.

The present invention is as described above, and one fixing bracket can be used even when there is only one square timber, or when the square timbers to be fastened are two pieces high, so it is convenient for selection, and the price of one fixture is reduced. Even if it is a little more expensive, the overall cost will be lower than if you prepare separate fixing brackets for one tube and two tubes, and the volume for transportation and storage will also be reduced, making it easier to build. This will help reduce costs.

In addition, when carrying out this invention, when two square pieces 22 and 23 are piled up, it goes without saying that they may be crossed or overlapped.

In addition, since the rod fixing rod 1 is formed by bending a rod-shaped body,
Compared to material machining or integral molding by casting, processing costs and material costs can be reduced, and it has sufficient strength, so it is safe for users. And it can be provided at low cost.

As explained below, the construction fixture according to the present invention is
It can support one or two square pieces in a stable state, and can be fastened with a very large force, and is safe for users and inexpensive. In addition to being able to be supplied, the volume for transportation and storage is also reduced, which has a beneficial effect in reducing construction costs.
