Description

[Detailed description of the invention] The present invention relates to a tool that can be easily assembled using two identical brackets and that can firmly attach an arch pipe. A girder pipe insertion hole 2 is provided approximately at the center of the front and rear plates of the U-shaped metal fitting that is bent and formed.
A wedge insertion groove 3 is bored from the inner periphery of the girder pipe insertion hole 2 on one side toward the arch pipe holding part 1 side and on the other side facing the opposite side of the arch pipe holding part 1. A cut groove 5 perpendicular to the longitudinal direction of the arch pipe holding part 1 is provided below the holding part 1.
The lower edge of the cut groove 5 is bent inside the arch pipe holding part 1 to form the arch pipe locking part 4.
It is made by using brackets A that are tied together to form a bracket A. 6 in the figure is a core material 7 for attaching an inner arch pipe formed downward from the center of the lower edge of the cut groove 5 of the arch pipe holding part 1.
It should be noted that both ends of the inner arch pipe mounting core material 7 are bent diagonally upward toward the outside. Reference numeral 8 denotes an arch pipe, one end of which is fitted into the arch pipe holding part 1 of the bracket A from above, and the lower end of the arch pipe 8 is fitted into the arch pipe locking part 4 protruding inside the arch pipe holding part 1. engaged and prevented from further appointment.
The other end of the arch pipe 8 is held by the arch pipe holding portion 1 of the adjacent bracket A. A wedge 9 is driven into a wedge insertion groove 3 connected to the girder pipe insertion hole 2 of the bracket A, and fixes the girder pipe 10 and the arch pipe 8.

11 is the bracket A in the longitudinal direction of the girder pipe 10
The seat mounting plate placed above, reference numeral 12, is a fixing wire insertion hole drilled above the front and rear plates of bracket A, through which the fixing wire that fixes the seat mounting plate 11 to bracket A is inserted. be.

Reference numeral 14 denotes an inner arch pipe that fits into the inner arch pipe mounting core material 7.

The present invention has the above-mentioned structure, but to explain its embodiment with reference to the drawings, as shown in FIG. The left and right wedge insertion grooves 3 bored in connection with the hole 2 are joined so that they match, and the 2
After inserting the brackets A into the girder pipe 10,
When the arch pipe 8 is inserted into the arch pipe holding part 1 of both brackets A, the lower end of the arch pipe 8 is formed by bending the lower edge of the cut groove 5 formed below the arch pipe holding part 1 inward. It is supported without coming off by the locking part 4, and the corresponding rear wedge insertion groove 3
By driving a wedge 9 into the arch pipe 8, the arch pipe 8 is fixed to the girder pipe 10.

Further, from above, fit the inner arch pipe mounting core material 7 into the fitting groove 6 of the inner arch pipe mounting core material, which is formed in the lower part so as to be connected to the cut groove 5 of the arch pipe holding part 1. When the inner arch pipe 14 is fitted into the inner arch pipe mounting core material 7, a double arch pipe with inner and outer sides is formed.

In addition, the installation of the arch pipe at the end of the row of buildings is as follows:
In this case, only one bracket needs to be used.

As mentioned above, in this case, the arch pipe can be easily installed using two identical brackets, and since the common wedge 9 is driven into the wedge insertion groove 3 of both brackets, the installation angle of the arch pipe 8 can be determined accurately and the arch pipe can be firmly fixed. This is a very effective and useful idea.

Claims (1)

[Scope of utility model registration request] At approximately the center of the front and rear plates of the U-shaped metal fitting, which is formed by folding the arch pipe holding part 1 in half on one side and forming a bend, there is a girder pipe insertion hole 2 and an arch from the inner periphery of the girder pipe insertion hole 2. A wedge insertion groove 3 is formed toward the pipe holding part 1 side, and the other side is directed toward the opposite side of the arch pipe holding part 1, and a wedge insertion groove 3 is formed below the arch pipe holding part 1 in the longitudinal direction of the arch pipe holding part 1. A series of brackets A each having orthogonal cut grooves 5 formed therein, and the lower edge of the cut grooves 5 being bent inside the arch pipe holding part 1 to form an arch pipe locking part 4.
