Problems solved by technology

[0002] In the existing building construction process, the floor-to-floor splicing has the disadvantages of insufficient strength and low safety and reliability. Sometimes it is necessary to increase the thickness and strength of the floor slab. If the steel plate or concrete slab is thickened to increase the thickness and strength, the cost is often tall and bulky

Embodiment Construction

[0013] like figure 1 , figure 2 As shown, a joist 1 is box-shaped or channel-shaped and welded by steel plates or channel steels. When using channel steel to make, the opening of channel steel should be downward, and its bottom is upward, and be drilled with connection hole 4, the size and position of described connection hole 4 should match with the steel frame of the floor slab on joist 1 top, with It facilitates the connection and assembly of the floor slab and the joist 1. The joists 1 can be bolted or welded under the steel frame of the floor slab. When the floors are spliced ​​together, the length of the joist 1 should be designed as the sum of the widths of the two floors, so that the two floors can be combined into a whole, the strength of the connection between the floors can be improved, and the splicing of the floors can be faster, safer and more reliable.

[0014] Both ends of the joist 1 are provided with end plates 2, and the end plates 2 are provided with co...

Abstract

The invention relates to a joist. The joist is box-shaped or tank-shaped. The upper surface of the joist is matched with a steel framework of a floor, and is provided with connecting holes. The joist is fastened below the steel framework in a bolt manner or a welding manner. The two ends of the joist are provided with end plates and horizontal reinforcing bars. The joist overcomes technical difficulties, namely jointing between structured floors, and reinforcement and elevating of floors, and can be used as positioning, supporting and connecting auxiliary devices.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a joist for improving floor strength, assisting floor splicing, and increasing floor height. Background technique [0002] In the existing building construction process, the splicing of floors and floors has the disadvantages of insufficient strength and low safety and reliability. Sometimes it is necessary to increase the thickness and strength of the floor. If the steel plate or concrete slab is thickened to increase the thickness and strength, it is often costly. Tall and bulky. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a joist that is convenient for connection, can improve floor strength, assist floor splicing, and increase the height of the interior space of the floor. [0004] The present invention is achieved through the following technical solutions: [0005] A joist, the jois...
