Problems solved by technology

However, due to the thin wall thickness of the formwork in the floor slab, it is easy to be damaged during transportation and construction, especially when it is hit or collided by various heavy objects and falling objects. Due to insufficient strength and poor impact resistance, damaged holes often appear , resulting in the destruction of the shell wall
Bring inconvenience to the construction, increase the cost, and affect the construction period

Embodiment Construction

[0072] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0073] As shown in the drawings, the present invention includes an upper plate 1 and surrounding side walls 2, and is characterized in that at least one thin strip 3 is sandwiched in at least one of the upper plate 1 and the surrounding side walls 2. 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 thin strip, and those with the same number have the same description. figure 1 Among them, a plurality of thin strips 3 are clamped in the upper plate 1 and the surrounding side walls 2 .

[0074] The invention is also characterized in that the thin strips 3 are arranged parallel or cross each other or in a web or a combination thereof, or simultaneously in one or more layers in the cement. figure 1 The thin strips 3 in the uppe...

Abstract

A thin-wall form for filling concrete in it to in-situ pour hollow non-beam floor is composed of top plate and peripheral wall, and is characterized by that at least one of said top plate and peripheral wall contains at least one thin strip for improving its resistance to impact and collision. Its advantages are simple structure and high resistance to deformation and vibration.

Description

(1) Technical field [0001] The invention relates to a thin-walled formwork for concrete filling. (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 durin...
