cast-in-place concrete slab

Abstract

The cast-in-place concrete slab is characterized in that the cast-in-place concrete slab includes cast-in-place reinforced concrete laminated ribs, cast-in-place reinforced concrete laminated beams, and prefabricated components, and the prefabricated components include a roof, a rib mold, a beam mold, a roof, a rib mold It forms a member with one side open with the beam formwork, the lower end of the rib formwork protrudes outwards to form the rib base formwork, and the lower end of the beam formwork protrudes outwards to form the beam base formwork. There are two opposite beam forms on the prefabricated component. The lower end of the rib formwork is lower than the lower end of the rib formwork. There is a beam-rib connecting formwork between the rib formwork and the beam formwork. The part of the beam formwork that is flush with the rib formwork is the beam upper formwork, and the part of the beam formwork that is lower than the rib formwork is the lower hanging beam formwork. The top plate is a forming mold for post-cast concrete, on which there is a cast-in-place concrete structural thin plate, and the beam bottom molds of the prefabricated components on both sides of the same line are adjacent to each other, and form a cast-in-place reinforced concrete composite beam together with the cast-in-place concrete. The rib molds are arranged adjacent to each other, together with the cast-in-place concrete to form a cast-in-place reinforced concrete laminated rib, and there are more than two cast-in-place reinforced concrete laminated beams arranged in the cast-in-place concrete slab.

Description

a technical field [0001] The invention relates to cast-in-place concrete slabs. Two background technology [0002] At present, many buildings adopt the method of cast-in-place concrete hollow floor slabs. The cast-in-place concrete floor slab can solve the problems of anti-seismic and cracking, but a large number of templates are used during construction, which not only increases the cost, but also slows down the construction speed and prolongs the construction period. Patent No. ZL00203695.9 is a utility model patent for "combined concrete hidden rib floor slab". It is composed of prefabricated thin plates, formwork, hidden ribs, and upper plates. The shell, the formwork includes the upper plate and the surrounding side plates, there are hidden ribs between the adjacent prefabricated thin plates or formwork, the upper plate covers the formwork, and is connected with the hidden ribs as a whole, and as the applicant applied for The invention patent application with the appl...

Problems solved by technology

In this way, during the construction of cast-in-place concrete slabs, because the lower end of the prefabricated beam formwork is lower than that of the rib formwork, there is a beam-rib connection form between the beam bottom formwork and the rib formwork, and the flush part of the beam formwork and the rib formwork is the beam upper formwork. The lower part of the formwork than the rib formwork is the lower formwork of the lower hanging beam, and its top plate is a forming form for post-cast concrete. After pouring a cast-in-place concrete structural thin plate on it, the surface of the cast-in-place concrete plate has good integrity and strong waterproof performance. The beam formwork and the beam bottom formwork of two prefabricated components are combined to form the cast-in-place concrete beam formwork. Correspondingly, the rib formwork and its rib-bottom formwork are combined to form the cast-in-place concrete rib formwork. There are cast-in-place concrete floor slabs, which can form large-span one-way cast-in-place prefabricated beam-rib cast-in-place concrete slabs. This prefabricated component solves the problem that the large-span beam-rib structure in the prior art cannot be cast in one time after setting prefabricated components. molding problem
