Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a connecting and fixing device for connecting and fixing two members.

Prior art and its problems For example, in assembled buildings such as sunrooms, storerooms, greenhouses, balconies, and verandas, two members, such as beams and girders, columns and girders, columns and beams, etc., are arranged at a predetermined angle with respect to each other. When connecting one member with the side surface of the other member in close contact with the end surface of the other member, this was done as follows. That is, by using a connector consisting of a first wall that is in close contact with the side surface of one member, and a second wall that is in close contact with the side surface of the other member and forms a predetermined angle with the first wall, 1
The two members can be separated by screwing a bolt passing through the wall into a screw hole provided in the one member, and by fitting a bolt passing through the second wall into a screw hole provided in the other member. were connected. However, in the conventional connection method, a small gap is created between the side surface of the one member and the end surface of the other member, resulting in a problem that the sealing performance between the two members is not sufficient.

The purpose of this invention is to provide a device for connecting and fixing two members that solves the above problems.

In this specification, the term "rear" refers to the side of the first member toward which the connecting and fixing surface faces, and the term "front" refers to the opposite side.

Means for solving the problem The device for connecting and fixing two members according to this invention is as follows:

A bolt insertion hole is formed in each of the two mutually parallel walls of the second member, and a long hole that is long in the front and back direction is formed in the mutually parallel wall of the connecting device, and the connecting device is made of a bolt for connecting and fixing. Two plate-like bodies are arranged inside both walls so as to be parallel to the walls and have screw holes, and both plate-like bodies can approach and separate from the wall while being parallel to the walls. The bolts are inserted into the bolt insertion holes and the elongated holes from the outside of both walls of the second member, respectively, so that they move forward when approaching and move backward when separating. It is screwed into a screw hole.

In the above, the first member is made of aluminum (including aluminum alloy; the same applies hereinafter);
Metal plates such as steel (including molded products from plates), pipes,
Any material can be used as long as it has a connecting and fixing surface that allows the second member to be brought into close contact with the second member, such as a rod, block, aluminum extrusion, or steel mold. The second member is made of, for example, a metal tube made of aluminum or steel, a molded product of a metal plate, an aluminum extrusion material, a molded steel, etc., and is formed at a predetermined angle to the connecting and fixing surface of the first member. A device with two closely spaced parallel walls is used. Further, in the above, the parallel wall of the second member and the connecting and fixing surface of the first member may form a right angle, or may form another predetermined angle. Furthermore, in the above, it is preferable to use a connector made of aluminum extrusion, aluminum casting, or the like. The screw holes in the plate-shaped body of the connector are provided by cutting a thread with a screw tap into the inner surface of the hole formed in the plate-shaped body, or by fixing a nut.
