Abstract
The utility model relates to a hollow building floor, in particular to a novel hollow floor with ribbed beams. The utility model aims to solve the problems in the prior art that in forming the hollow floor, a die is floated upwards and an upper plate and a lower plate are different in thickness. The utility model provides the novel hollow floor with the ribbed beams, and adopts the technical scheme that prefabricated cavity members and cast-in-situ reinforced concrete ribbed beams are included; the upper surface of the floor is formed by the upper surface of the ribbed beams and the upper surface of a top plate; and the lower surface of the floor is formed by the lower surface of the ribbed beams and the lower surface of a baseplate. The utility model has the benefits that the construction difficulty of a traditional hollow floor with ribbed beams is reduced. Compared with the prior art, the hollow floor has the characteristics that the girder ribs are narrow, the rib intervals are small, the ribbed beams can be crossed and restrained with each other, and the carrying capacity is greatly improved. The thickness of the upper plate and the lower plate in prefabrication can be reduced, and the structure of concrete is more compact and reliable.
Description
Technical field
The utility model relates to a kind of building hollow building cover, specifically a kind of novel close girt strip hollow building cover.
Background technology
In present building hollow building cover, the upper plate of reinforced concrete ribbed beam, flat beam, peripheral collar tie beam (Vierendeel girder or fore shaft beam), hollow building cover all is cast in situs, the lower plate cast in situs of hollow building cover or prefabricated.Under present technical condition, hollow building cover forms the complex process of cavity, and the on-site concrete amount of building is big, and the thickness of upper and lower plates is difficult to guarantee that the thickness deficiency has potential safety hazard that the excessive material of not only having wasted of thickness has also strengthened deadweight.
Summary of the invention
The purpose of this utility model is to overcome the mould come-up brought when thin-walled box in the prior art, bamboo core, core, honeycomb core form hollow building cover, the problem that differs of thickness of slab up and down, and a kind of novel close girt strip hollow building cover is provided.
Concrete technical scheme of the present utility model is: novel close girt strip hollow building cover, it comprises that flat beam, peripheral frame are set a roof beam in place, prefabricated cavity member and the close girt strip of cast-in-situ steel reinforced concrete, described prefabricated cavity member comprises top board, base plate and side plate, and the side plate two ends connect top board and base plate respectively; Gap between prefabricated cavity member and the prefabricated cavity member is provided with reinforcing bar, forms close girt strip behind the pour concrete; Being by the forming above of the top and top board of close girt strip above the described superstructure, is forming below by the following and base plate of close girt strip below the superstructure.
The same direction of described close girt strip is arranged in parallel, and two to mutual square crossing arrangement.
Set a roof beam in place with peripheral frame with flat beam respectively and be connected in described close girt strip two ends.
Described superstructure thickness is 250 to 1500mm; Described close girt strip width is 80 to 200mm; Spacing between the described two parallel close girt strips is 300 to 1800mm.
Described top board and base plate have one at least, establish in it to connect and overhanging connecting lacing wire.
Described top board, base plate and side plate have one at least, and its outer periphery is provided with the build-in tooth.
Described top board and side plate are made as one in advance.
Described base plate and side plate are made as one in advance.
The horizontal profile of described prefabricated cavity member is rectangle, square or circular.
The beneficial effects of the utility model are: construction reinforced bar concrete ribbed beams hollow building cover is more convenient, faster, more economical with materials, easier assurance crudy and site operation quality; Reduced the difficulty of construction of traditional close girt strip hollow building cover.Compare with prior art and to have that the beam rib is narrow, rib spacing is little, and cross-over constraint and increase substantially characteristics such as supporting capacity mutually.Prefabricated that thickness is dropped to is minimum in processing for upper and lower plates, and quality of concrete is more closely knit, more reliable.
