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, and it is not convenient for assembly line production. Especially in the transportation and construction process, the formwork transportation is extremely inconvenient, and the overall formwork components occupy a lot The transportation space wastes a lot of transportation resources and increases the transportation cost. Moreover, the formwork is easily damaged due to bumps, extrusions and collisions during transportation, and the damage rate is high. The construction cost of the corresponding cast-in-place concrete hollow slab is high. Therefore, It is urgently needed to develop a new cavity formwork member for cast-in-place concrete hollow slabs.

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 (2). The invention is characterized in that the enclosed cavity shuttering component (2) consists of a precast groupware (7) through splicing; the precast groupware (7) is composed of at least two precast slabs (8); the precast upper plate (4) or the superposed precast groupware (7) is thicker or thinner than the surrounding side wall (5), 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 200510074457.8, 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...
