Mould case structural member

Abstract

The invention relates to a mould case structural member, which comprises basin-shaped moulds (1), wherein the basin-shaped moulds (1) are an integral structural member. The member is characterized inthat basin openings of the two basin-shaped moulds (1) are relatively buckled, and the buckling positions of the two opposite basin openings are jointed by a ridge keel (2) to form an integral mould case structural member. Therefore, the mould case structural member improves various performances of the splicing position of the basin openings of the basin-shaped moulds obviously, and can effectively reduce the damage rate of the mould case structural member and reduce the cost; and in addition, the ridge keel and the basin-shaped moulds are subjected to tight treatment, and after being appliedto cast-in-situ reinforced concrete floors, the mould case structural member can prevent the entry of cast-in-situ concrete, moisture and air bubbles effectively, improve the integral quality of the cast-in-situ reinforced concrete floors and reduce phenomena of hollowing and cracking, is suitable to be used in hollow floors, roofs, wall bodies, foundation slabs and hollow bridges of various kindsof cast-in-situ reinforced concrete or prestressed reinforced concrete, and is particularly suitable to be used in hollow beamless floors.

Description

(1) Technical field [0001] The present invention relates to a formwork member. (2) Background technology [0002] 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 problems, many buildings have adopted the method of cast-in-place concrete floor slabs (hollow, solid). Although the cast-in-place concrete floor slab solves the problems of earthquake resistance and cracking, a large number of templates are used during construction, wh...

Problems solved by technology

The formwork components used in this floor slab include an upper shell and surrounding side shells, and the upper shell and the surrounding side shells are enclosed with each other to form an open basin-shaped cavity component. However, when this type of basin-shaped cavity component is made, the overall Molding is troublesome, labor-intensive and time-consuming, and the cost is high, and there is no reinforcement measure at the splicing joint. The joint is a weak area of ​​the components, which is extremely easy to be damaged, causing the entire component and even the application of the floor to cause damage to the entire floor. , therefore, it is urgently needed to develop a new formwork member
