Description

Cantilever beam structure

Technical Field

Background

In the field of buildings, particularly high-rise buildings, the building of external frames is a prerequisite for other constructions. However, considering the strength of the steel pipe of the built external frame, when the floor reaches a certain height, the structure of the cantilever frame is adopted, namely, when concrete is poured on the low floor, I-shaped steel is embedded through the wall in advance and extends out of the building by a certain length, and the outward extending parts are used as bearing points of the external frame of the higher floor. The embedding direction, the extending length and the like of the I-shaped steel are arranged according to specific design.

Because the cantilever frame damages the wall body, the using amount of steel is large, the later construction is hindered, and the installation and the removal are labor-consuming, various attempts are made in the industry for modification. The prior successful scheme is that a plurality of linking points are embedded in advance before concrete pouring, the cantilever beam only selects the section extending out of the wall body originally, a connecting plate is welded, corresponding holes are arranged on the linking plate, and the holes are connected in series with the embedded points by screws and are fixed, so that the cantilever beam is fixed on the wall body. Because the embedding direction of the cantilever beams is not fixed, the cantilever beams are generally arranged along the circumference of the building body on the same layer, as shown in figure 1. When the cantilever beam is at a corner, the common plane rectangular connecting plate is not suitable any more, and the current common practice is to make a connecting plate with an angle consistent with the angle of the corner of the wall body, or weld the connecting plate and the cantilever beam according to a certain angle in advance, and when the cantilever beam is at the corner, fix the connecting plate on one of the planes of the corner, so that the cantilever beam is supported at the set position of the corner in an inclined manner.

However, both of these approaches require special customization and are difficult to apply universally.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

The utility model provides a pair of cantilever beam structure belongs to an improvement of current cantilever beam structure. As shown in fig. 3, the steel pipe fixing device specifically comprises a cantilever beam 1, a connecting plate 2 and a steel pipe fixing piece 3, wherein the connecting plate 2 further comprises a fixing protrusion 21 and a first fixing screw 22. The cantilever beam is provided with a first through hole at a corresponding position, and the fixing protrusions 21 are provided with second through holes and are arranged in an up-and-down symmetrical manner (in the figure, the fixing protrusions below are not shown). The cantilever beam 1 is placed between the upper fixing bulge 21 and the lower fixing bulge 21, the angle between the cantilever beam 1 and the connecting plate is adjusted, and then the first fixing screw 22 sequentially penetrates through the second through hole of the upper fixing bulge 21, the first through hole of the cantilever beam 1 and the second through hole of the lower fixing bulge 21 and is fixed through the nut.

In actual operation, the utility model discloses can fix the hitch plate on the wall body earlier, fix the cantilever beam at the hitch plate again, like this when fixed cantilever beam, only need the operator lift a little can, can further practice thrift operator's physical power.

In particular, as shown in fig. 4, the utility model discloses the mounting of pull rod no longer welds a pull ring in a certain position of cantilever beam, but directly perforates on the vertical steel sheet of cantilever beam of settlement position to the steel sheet that has the through-hole of the same size in the welding of through-hole both sides is as pull rod mounting 11, corresponds the position opening in the last plane of cantilever beam, so that the pull rod penetrates, for satisfying design intensity, can set up the strengthening rib (not drawn in the picture) around the pull rod mounting.
