Abstract

The utility model relates to a facility for suspending a supporting structure, in particular to a key keel of a curtain wall used in the decoration engineering of an outer wall. The key keel of the curtain wall comprises a U-shaped frame; the rear ends of a left side plate and a right side plate of the U-shaped frame are respectively provided with a left connecting plate and a right connecting plate that extend outwards transversely; the left connecting plate and the right connecting plate are respectively provided with more than one first waist-shaped holes; and more than one second waist-shaped holes are arranged on the front end surface of the U-shaped frame. The key keel of the curtain wall does not need the welding operation in the installation process and can be directly connected with a trench type embedded part by a T-shaped bolt, therefore, the quality defect caused by the high-altitude welding operation can be avoided, the installation is fast, the labor and time can be saved, and the operation efficiency can be improved.

Description

The curtain wall main joist

Technical field

The utility model relates to a kind of facility of hanger bearing structure, particularly relates to a kind of curtain wall main joist that is used in the decoration of exterior wall engineering.

Background technology

In the exterior wall decorative engineering, external wall decorative material generally all is fixing on the wall by the keel frame, and the most welding manners that adopt of existing keel frame connect, and is not only unadjustable and weight is very big; In addition, in construction, need fill insulant material between curtain wall and the body of wall, easily produce spark during welding, cause fire to suffer from, and the steel surface material is caused damage, influence application life.

The utility model content

For addressing the above problem, the utility model provides a kind of light and fast, saving of work and time, has improved time that curtain wall installs and the curtain wall main joist that need not weld greatly.

The utility model curtain wall main joist, comprise U type frame, the rear end of two side plates is respectively equipped with the left junction plate and the right junction plate of horizontal expansion laterally about described U type frame, be equipped with more than one first mounting hole on left side junction plate and the right junction plate, the front end face of described U type frame is provided with more than one second mounting hole.

The beneficial effect of the utility model curtain wall main joist is: the curtain wall main joist need not weld job in installation process, directly is connected with the slot type built-in fitting by T type bolt, the mass defect of avoiding the high-altitude welding to be caused, quick for installation, saving of work and time; Because the front end face of left junction plate and right junction plate and U type frame is stressed different, so that the size of the size of first mounting hole and second mounting hole also designs is different, can conveniently use different T type bolts to connect like this, improved operating efficiency greatly.

The specific embodiment

Below in conjunction with Figure of description the utility model curtain wall main joist is described further.

Referring to Fig. 1 and Fig. 2, the curtain wall main joist of the utility model embodiment 1, comprise U type frame 1, be respectively equipped with the left junction plate 2 and the right junction plate 3 of horizontal expansion laterally in the rear end of about 1 two side plates of U type frame, be equipped with more than one first mounting hole 4 on left side junction plate 2 and the right junction plate 3, the front end face of U type frame 1 is provided with more than one second mounting hole 5 of a row.

Referring to Fig. 3 and Fig. 4, the curtain wall main joist of the utility model embodiment 2, as different from Example 1, the front end face of U type frame 1 is provided with more than one second mounting hole 5 of two rows.

The utility model curtain wall main joist passes through cold roll forming, in installation process, need not weld job, second mounting hole 5 is connected with secondary joist by cup head T type bolt, first mounting hole 4 is connected with the slot type built-in fitting by T type bolt, avoid the high-altitude welding to make the mass defect that causes, quick for installation, saving of work and time, improved operating efficiency greatly.

Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.

Claims

1. curtain wall main joist, comprise U type frame (1), the rear end of two side plates is respectively equipped with the left junction plate (2) and the right junction plate (3) of horizontal expansion laterally about described U type frame (1), be equipped with more than one first mounting hole (4) on described left junction plate (2) and the right junction plate (3), the front end face of described U type frame (1) is provided with more than one second mounting hole (5).
