Problems solved by technology

However, when the formwork components in this floor slab are produced, it is inconvenient to make, the production efficiency is low, it is not convenient for assembly line production, the production cost is high, and the construction cost of the corresponding cast-in-place concrete hollow slab is high. Therefore, a new type of in-situ concrete is developed. Cavity formwork components for pouring concrete hollow slabs are in urgent need

Embodiment Construction

[0088] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0089] In the present invention, as shown in the accompanying drawings, the cavity formwork member 2 includes an upper plate 4, surrounding side walls 5, and a lower plate 6, and the upper plate 4, the surrounding side walls 5, and the lower plate 6 form a closed cavity formwork member, which It is characterized in that the upper plate 4, the surrounding side wall 5 and the lower plate 6 of the closed cavity formwork member 2 are composed of a component 7, and the component 7 is an actual structure of at least one prefabricated plate 8 and at least one bonded prefabricated plate 8. The pouring plate sheet 9 is formed, and the surrounding side walls 5 are formed by more than two prefabricated sheets 8 . In each drawing, 1 is reinforced concrete, 2 is cavity formwork member, 3 is cast-in-place reinforced concrete rib, 4 is upper plate, 5 is surrounding si...

Abstract

The invention relates to a cavity shuttering component used for a cast-in-situ reinforced concrete cored slab, the cavity shuttering component (2) comprises an upper plate (4), a surrounding side wall (5) and a lower plate (6); wherein, the upper plate (4), the surrounding side wall (5) and the lower plate (6) form the enclosed cavity shuttering component. The invention is characterized in that the upper plate (4), the surrounding side wall (5) and the lower plate (6) of the enclosed cavity shuttering component (2) respectively consist of a groupware (7) which consists of at least a precast slab (8) and at least a cast-in-situ flat bar (9) of the bonding precast slab (8); the surrounding side wall (5) consists of more than two precast slabs (8),therefore, the invention is applicable to cast-in-situ reinforced concrete or a hollow floor system, a roof system, walls and a foundation slab of the prestressed reinforced concrete as well as a vierendeel bridge girder, and is particularly suitable for a hollow flat slab.

Description

[0001] This application is a divisional application of an invention patent application with an application date of June 6, 2005, an application number of 200510074455.9, and a title of "a cast-in-place concrete hollow slab". (1) Technical field [0002] The invention relates to a cavity formwork component for cast-in-place concrete hollow slabs. (2) Background technology [0003] At present, most of the buildings with brick-concrete structure and frame structure use prefabricated hollow-core slabs as floor slabs. This kind of floor slab has the advantages of fast construction speed and low cost, but because there is no firm connection between two adjacent prefabricated hollow-core slabs , Only cement mortar is used to fill the gaps, so not only the integrity is poor, which is not conducive to earthquake resistance, but also cracks and water seepage often occur in the gaps, causing great inconvenience and psychological pressure to the residents. In order to solve the above pr...
