Problems solved by technology

This device is used for the construction of prefabricated laminated concrete slabs. Although the structure is simplified, it brings the risk of instability of the support system
[0009] The applicant found through careful research in the work that the risk of this support system is mainly due to the fact that in the existing construction technology, the laminated slab is only an independent existence, which completely relies on the support of the support system, and there is no effective formation between the laminated slabs. connection, which is the source of systemic instability

Embodiment 1

[0061] see Figure 1 to Figure 12 , an embodiment of the present invention provides a laminated slab for a prefabricated building, which includes a steel mesh and precast concrete partially poured on the steel mesh;

[0062] The reinforcement mesh includes several reinforcement frames 100 arranged side by side;

[0063] The steel bar frame 100 includes three straight bars 110 arranged in the shape of "品", a number of supporting pieces 120 that are respectively matched with the three straight bars 110 and evenly arranged along the centerline direction of the straight bars 110, and correspondingly located on the straight bars 110. Two connectors 140 at both ends;

[0064] The straight ribs 110 include a top straight rib 101 at the top of the "pin" shape, and two foot straight ribs 102 at the bottom of the "pin" shape;

[0065] The connectors 140 are matched with the two leg straight ribs 102 respectively;

[0066] The top of the support sheet 120 and the top straight bars 101...

Embodiment 2

[0089] On the basis of embodiment 1, the others are the same as embodiment 1, and the difference from embodiment 1 is: the top straight rib 101 is set as angle steel or channel steel, and the contour of the corresponding first perforation 121 in the supporting sheet 120 is corresponding to it. corresponding, see attached Figures 12 to 14 .

[0090] Or the top straight bar 101 is set as a steel pipe, round steel pipe or square steel pipe can be used, and high-strength concrete is poured in the steel pipe, so that the steel pipe forms a solid structure, which can further improve the bending strength of the laminated slab, especially can make the laminated slab It has strong bending resistance, and the contour of the corresponding first perforation 121 in the supporting sheet 120 corresponds to it, see the attached Figure 15 , 16 .

Abstract

The invention discloses a laminated slab for a fabricated building and a construction method, and belongs to the technical field of laminated slabs. According to the technical scheme, the laminated slab for the fabricated building comprises a reinforcing mesh and precast concrete locally poured on the reinforcing mesh; the reinforcing mesh comprises a plurality of reinforcing frames arranged in parallel; the steel bar frame comprises three straight bars arranged in the shape of a Chinese character'pin ', a plurality of supporting pieces matched with the three straight bars respectively and evenly arranged in the direction of the center lines of the straight bars, and two connecting pieces correspondingly located at the two ends of the straight bars. The straight ribs comprise a top straight rib positioned at the top of the Chinese character'pin 'and two foot straight ribs positioned at the bottom of the Chinese character'pin'; and the connecting piece is respectively matched with the two foot straight ribs. The laminated slab for the fabricated building has the beneficial effects that the laminated slab for the fabricated building is simple in structure, low in manufacturing cost, stable in structure and low in cracking risk, and the provided construction method saves time and labor and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of laminated panels, in particular to a laminated panel used for prefabricated buildings and a construction method. Background technique [0002] Laminated slab, in prefabricated buildings, the thickness of the laminated slab is usually between 5 cm and 8 cm, and a complete floor layer is formed by pouring concrete on its upper part. Usually, in the laminated slab, there are horizontal, vertical, or grid-shaped steel bars, which are also called structural steel bars, and the layered arrangement is realized by supporting the steel bars. Among them, during the pouring process of the laminated slab, the lower part is supported by the laminated slab support system. The laminated slab itself can be used as the base form for pouring, and there is no need to set a separate formwork for the cast-in-place concrete. Therefore, the laminated slab technology itself has good crack resistance and is not It has the advant...
