Cast-in-situ reinforced concrete hollow storey cover

Abstract

A cast-in-place reinforced concrete hollow floor, comprising reinforced concrete (1), hollow pipes (2), the hollow pipes (2) embedded in the reinforced concrete (1), plugs (3) at both ends of the hollow pipes (2) ) to seal the hollow tube (2) to form a closed cavity (4), which is characterized in that the sealing plug (3) at least one end of the hollow tube (2) is provided with a docking device ( 5). In this way, during the construction of the cast-in-place reinforced concrete hollow floor, the hollow pipes (2) are provided with butt joint devices (5) for connection and positioning, so the pipe bodies are conveniently arranged and connected without displacement or dislocation of each other, and the construction is easy, and the There will be inconsistencies in the width of the cast-in-place concrete ribs between the pipes and the inconsistency of the thickness of the concrete protective layer outside the pipes, etc., which ensures the overall quality of the cast-in-place reinforced concrete hollow floor, meets the requirements for the mechanical performance of the floor, and reduces the Construction costs.

Description

(1) Technical field [0001] The invention relates to a cast-in-situ reinforced concrete hollow floor. (2) Background technology [0002] At present, most buildings with brick-concrete structure and frame structure use prefabricated hollow slabs as floor slabs, which have the advantages of fast construction speed and low cost. However, because there is no firm connection between two adjacent prefabricated hollow slabs, only cement mortar is used to fill the joints, so the integrity is poor, which is not conducive to earthquake resistance, and cracks and water seepage often occur in the gaps. In order to solve the above problems, many buildings adopt the method of cast-in-place concrete floors (solid and hollow), which better solve the problems of earthquake resistance, cracking, water seepage, etc., but the construction of such floors is relatively difficult and the cost is relatively high . With the development of construction technology and economy, higher requirements are...

AI Technical Summary

Problems solved by technology

During the construction of this type of cast-in-place concrete hollow floor, the hollow pipes are prone to displacement or misalignment with each other, and the layout is inconvenient. Inconsistency and other phenomena, thereby affecting the overall quality and mechanical performance of the cast-in-place concrete hollow floor, increasing the difficulty of construction, therefore, it is urgently needed to develop a new type of cast-in-place reinforced concrete hollow floor
