Abstract

Disclosed is a shuttering member, which comprises an upper board and peripheral side panels, the upper board and the peripheral side panels encloses an open basin shape component, characterized in that at least one of the vertical corner positions of at least one peripheral side panels employs a vertical chamfering, thus, when the shuttering member is applied to the cast-in-situs of concrete hollow building covers, a reinforced rib for cast-in-situs concrete hidden rib can be formed at each chamfering positions, therefore effectively eliminating the stress concentration phenomenon on the building cover, preventing cracks and destruction by action of concentrated big load. If the shuttering member are closely spaced, the cast-in-situs concrete can form the shearing piers or columns of the building cover at the vertical chamfering position, thus greatly reducing the consumption of reinforcing steel, the shuttering member also has the advantages of reducing building roof weight, improving earthquake resistant behavior, bettering earthquake resistant behavior of the building cover, thus adapted for the application of hollow building cover, room cover, wall, foundation slab and laced beam bridges of the cast-in-situs reinforcing steel concrete or prestressed reinforcement concrete.

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, 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, which not only...

Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0054] As shown in the accompanying drawings, the present invention includes an upper plate 1, a surrounding side wall 2, and the upper plate 1 and the surrounding side walls 2 form an open basin-shaped member, which is characterized in that at least one of the at least one surrounding side wall 2 The vertical corner part is a vertical chamfer 3. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In each accompanying drawing, 1 is an upper plate, 2 is a surrounding side wall, and 3 is a vertical chamfer. In the following accompanying drawings, those with the same number have the same description. Such as figure 1As shown, the upper plate 1 and the surrounding side walls 2 form an open basin-shaped member, and the vertical corners on the surrounding side walls 2 are provided with vertical chamfers 3 .
