Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation. It should be understood that the following description is only used to clearly illustrate the present invention, not to limit it.

[0029] refer to Figure 1 to Figure 3 , shows that the cantilevered steel beam is fixed by a turnable double-rib cantilevered steel beam fixing device, and the cantilevered steel beam in this embodiment is an I-beam. The cantilever steel beam fixing device according to the present invention is composed of a double-rib snap ring 2, an L-shaped connecting rod 3 and an elastic snap ring 6 at the end of the L-shaped connecting rod 3, and the like. The double-rib clasp 2 is composed of two vertically parallel U-shaped vertical arm ribs 2-1 and two transversely parallel gluten bars 2-2, and is used to clamp the steel beam 4 from the top of the steel beam 4. Each U-shaped vertical arm rib 2-1 is vertically connected wi...

Abstract

The invention provides a returnable dual rib type cantilever steel beam fixing device and a construction method thereof. The returnable dual rib type cantilever steel beam fixing device comprises a steel beam fixing part. The steel beam fixing part which is a dual rib snap ring is formed by encircling two transversely arranged surface tendons and two longitudinally arranged U-shaped vertical walltenons. The length of the surface tendon is greater than the width of the surface of a steel beam. The top end of a U-shaped opened end of each vertical wall tenon is separately connected to one endsof the same side of the two surface tenons. A steel beam locking part connected to the two vertical wall tenons penetrate holes above U-shaped closed ends of the two vertical wall tenons. The steel beam locking part is a connecting rod provided with anti-skid structures at two ends. The height of the vertical wall tenon is equal to sum of the height of the steel beam, the thickness of a concrete floorslab and the diameter of the steel beam locking part. The dual rib snap ring can be used repeatedly, and is easy to mount and detach, low in manufacturing cost, few in outside influence factor andwide in application range.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a turnable double-rib type cantilevered steel beam fixing device and a construction method thereof, which are used in the construction of a cantilevered scaffold for the main structure of a high-rise building. Background technique [0002] In the prior art, the construction method of the cantilevered scaffolding construction of the main structure of high-rise buildings used to fix the cantilevered steel beams mainly includes: (1) using steel bars to make shaped anchor rings, and installing the steel bar anchor rings during the roof steel bar binding process , the floor is poured with concrete to fix the anchor ring, and the steel beam is inserted and fixed after the concrete strength meets the requirements; The beam is put in, and the angle steel is flattened on the upper part to tighten the nuts. The above method has the following limitations: (1) The installation of the st...
