Problems solved by technology

[0010] The technical problem to be solved by the present invention is: when producing hollow laminated floor slabs with large spans in the prior art, the rigidity of the components during production, transportation, construction and installation is insufficient, or due to the increase in the thickness of the bottom plate, it is impossible to bear two-way force, and there are also Due to the increase of rigidity due to the double-layer slab, the hollow rate is low, and the production and construction are difficult

Embodiment Construction

[0046] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] Such as Figure 5 The reinforced concrete hollow laminated two-way densely ribbed slab shown includes the bottom formwork of the floor slab and the top slab 4. The bottom formwork of the floor slab is composed of several pieces of concrete inverted T-shaped ribbed slabs assembled and combined. The structure of the concrete inverted T-shaped ribbed slab is shown in Figure 1-3 , the concrete inverted T-shaped ribbed floor is an ordinary concrete inverted T-shaped ribbed floor or a prestressed concrete inverted T-shaped ribbed floor.

[0048] The concrete inverted T-shaped ribbed floor is formed by integral casting of the lower flat plate 5 and the longitudinal rib beams 2 arranged along its length direction. Wherein, the interior of the lower plate 5 is provided with a two-way steel mesh. According to the span, the lower plate 5 can be provided with transverse...

Abstract

The invention belongs to the technical field of building engineering, and provides a reinforced concrete hollow superposed two-way dense rib floor and a construction method thereof. The floor is divided into common reinforced concrete and pre-stressed concrete, and is suitable for industrial and civil building floors and roof boards with spans of more than 6 meters. The reinforced concrete hollowsuperposed two-way dense rib floor is assembled into a floor bottom die by using a plurality pieces of prefabricated reinforced concrete (or pre-stressed concrete) ribbed bottom plates, a light or hollow material is arranged on the ribbed bottom plate to reduce the dead weight of the structure, the concrete is poured after the longitudinal and transverse rib beam steel bars are paved, and after the construction and curing is finished, an assembled integral reinforced concrete hollow superposed two-way dense rib floor is formed. According to the invention, the floor is in accordance with the standardization and the modular requirements of the industrial production of the current building, the floor can be produced by using the equipment in most prior factories, and the production process issimple. The prefabricated reinforced concrete ribbed bottom plate is assembled on site, no formwork is needed, only a small amount of supports are needed, so that a large number of formworks and labors are saved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and specifically relates to a floor covering and its manufacturing and construction methods. Background technique [0002] The currently disclosed technical scheme of the reinforced concrete hollow composite floor used in the construction project is as follows: [0003] (1) Chinese invention patent "a laminated floor slab (patent number 2015105065844)", which includes several prefabricated reinforced concrete slabs and T-beam slabs, at least one slab is spliced ​​between two adjacent T-beam slabs, and they are passed through post-cast reinforced concrete The laminated floors form an integral laminated floor slab. It reduces the amount of concrete, self-weight, and cost through prestressing technology and the structure of two-way dense rib sandwich, and improves its own rigidity and bearing capacity. , reducing the influence of thermal bridges of the longitudinal and transverse ...
