Problems solved by technology

This kind of cast-in-place reinforced concrete hollow floor, because the tubular concrete in the center of the lightweight tube used for filling has been evacuated, there are cast-in-place concrete ribs along the longitudinal direction of the tube, and because the reinforced concrete has been evacuated by the mandrel or components in the transverse direction, there are The cast-in-place reinforced concrete hollow slab has a large difference in rigidity in two directions, and becomes a cast-in-place reinforced concrete hollow one-way slab, which has the disadvantages of large consumption of reinforced concrete, heavy weight, poor seismic performance, and large difference in two-way rigidity.

Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] As shown in the accompanying drawings, the present invention includes a reinforced concrete 1 and a light pipe 2, and the light pipe 2 is embedded in the reinforced concrete 1, and is characterized in that at least one section of horizontal pipe protrudes from the light pipe 2 Body 3. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In each accompanying drawing, 1 is a reinforced concrete, 2 is a lightweight pipe, and 3 is a horizontal pipe body protruding from the lightweight pipe 2. In each accompanying drawing, those with the same number have the same description. Such as figure 1 As shown, a horizontal pipe body 3 protrudes from the light pipe 2, and the cast-in-place reinforced concrete ribs between the light pipes 2 become cast-in-place concrete ribs with reinforced piers.

Abstract

The invention is a spot-poured reinforced concrete building cover, including reinforced concrete and light pipe, where the light pipe is buried the reinforced concrete, and its character: there is at least a section of transverse pipe extending out of the light pipe. Thus, because of the transverse pipe, it further hollows out the concrete, so it has small concrete consumption, its dead weight is low, its shock resisting property is good, its lengthways rigidity is weakened relatively, and its bidirectional rigidity difference is reduced.

Description

(1) Technical field [0001] The invention relates to a cast-in-place reinforced concrete 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 put f...
