Light steel paired joist connection structure and its connection method

Abstract

The present invention disclooses a connecting structure of lightgage steel joist pair and its connecting method. It is characterized by that the connection between two joist bodies with groove has noconnecting component, but one end of one joist bodyis equipped with a tenon head, and on two side walls of said tenon head a fastening hook projected outward is set respectively, and on two side walls of one end of another joist a fastening groove is set respectively, said fastening grooves are matched with the above-mentioned fastening hooks. If the above-mentioned tenon head of one joist is inserted into the groove of another joist, and the fastening hjooks of one joist are fit into the fastening grooves of another joist, so that a new connection structure of them can be formed.

Description

Technical field: [0001] The invention relates to a light steel keel for construction, in particular to a connection structure and a connection method of a light steel auxiliary keel. Background technique: [0002] The inventor once invented "self-connecting light steel keel", Chinese patent number: 97231611.6, which only solved the problem that the main keel does not need to be extended with accessories. Difficult, so the new structure of the connection of the auxiliary keel has not been solved. In order to lengthen the light steel auxiliary keel, the traditional connection structure of the light steel auxiliary keel is still between the two auxiliary keels, such as A auxiliary keel body and The connection between the auxiliary keel bodies of B depends on a special connecting piece, and the two ends of the connecting piece are respectively inserted into the grooves at the ends of the auxiliary keel body of A and B, so as to achieve the connection between the two keel bodies ...

[0002] The inventor once invented "self-connecting light steel keel", Chinese patent number: 97231611.6, which only solved the problem that the main keel does not need to be extended with accessories. Difficult, so the new structure of the connection of the auxiliary keel has not been solved. In order to lengthen the light steel auxiliary keel, the traditional connection structure of the light steel auxiliary keel is still between the two auxiliary keels, such as A auxiliary keel body and The connection between the auxiliary keel bodies of B depends on a special connecting piece, and the two ends of the connecting piece are respectively inserted into the grooves at the ends of the auxiliary keel body of A and B, so as to achieve the connection between the two keel bodies or the extension of the auxiliary keel. purpose, but this connection has the following disadvantages: due to the large fit gap between the auxiliary keel and the connecting piece, the joint is often very loose, the accuracy and safety of the extended lap joint are low, and the construction is inconvenient. Parts need to be specially produced, which increases the troublesome links in production and management, and the cost is also high
