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

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] As shown in the accompanying drawings, the present invention includes reinforced concrete 1 and hollow pipe 2. The hollow pipe 2 is embedded in the reinforced concrete 1. The sealing plugs 3 at both ends of the hollow pipe 2 seal the hollow pipe 2 to form a closed cavity 4. It is characterized in that the sealing plug 3 at least one end of the hollow tube 2 is provided with a docking device 5 for connection and positioning between the hollow tubes 2, and the hollow tube 2 is filled with a tubular light material. Fig. 1 is a schematic structural diagram of Embodiment 1 of the present invention. In each accompanying drawing, 1 is reinforced concrete, 2 is a hollow pipe, 3 is a plug at both ends of the hollow pipe 2, 4 is a closed cavity in the hollow pipe 2, and 5 is a hollow pipe provided on the sealing plug 3 of the hollow pipe 2. The docking de...

Abstract

Disclosed is a cast-in-situ reinforced-bar concrete hollow building slab, which comprises a reinforced-bar concrete (1) and a hollow tube (2), the hollow tube (2) is embedded in the reinforced-bar concrete (1), the sealing bulkheads (3) on the two ends of the hollow tube (2) seal the hollow tube (2) into a confined chamber (4), characterized in that the sealing plug of at least one end of the hollow tube is provided with an positioning arrangement between the hollow tubes (2), the hollow tube (2) is filled by tubular solid lightweight materials. The invention can be applied to cast-in-situ reinforced concrete or prestressed reinforcement concrete's hollow storied-building roofings, house roofings, walls, foundation bedplates and hollow bridges, especially for hollow flat slabs.

Description

[0001] This application is a divisional application of an invention patent application with an application date of February 26, 2003, an application number of 03118108.2, and a title of "a cast-in-place reinforced concrete hollow floor". (1) Technical field [0002] The invention relates to a cast-in-situ reinforced concrete hollow floor. (2) Background technology [0003] 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 proble...
