Abstract
The utility model relates to a precast beam formula folded plate stair improve structure, including two boundary beams and folded plate, two parallel opposition of boundary beam erect, the folded plate is located between two boundary beams, and the corresponding boundary beam is connected respectively to the folded plate both sides, the folded plate is the ladder platelike, all steps up with the echelonment between the bottom surface of folded plate and the top surface, and upper end, the lower extreme of folded plate all are provided with the opening moreover, the thickness of boundary beam is 130mm. Precast beam formula folded plate stair cancel and seal the roof beam, and the component production drawing of patterns is easier, prescribes a limit to 130mm with boundary beam thickness moreover, alleviates component weight, more is favorable to the tower crane hoist and mount.
Description
Technical Field
The utility model relates to a precast beam formula folded plate stair improves structure.
Background
The existing precast beam type folded plate stair is as shown in figure 1, and because the upper end and the lower end of the folded plate 2 are both provided with the sealing beam 4, when the precast beam type folded plate stair is produced, the sealing beam part is difficult to demould, and the side beam 1 of the existing precast beam type folded plate stair is large in size (150 mm in thickness), so that the weight of the precast beam type folded plate stair is heavier, and the precast beam type folded plate stair is not beneficial to tower crane hoisting.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prefabricated beam type folded plate stair improvement structure that the drawing of patterns is easy, weight alleviates.
The purpose of the utility model is realized like this:
the utility model provides a prefabricated beam type folded plate stair improve structure, includes two boundary beams and folded plate, and two parallel opposition of boundary beam erect, the folded plate is located between two boundary beams, and the corresponding boundary beam is connected respectively to the folded plate both sides, the folded plate is the ladder platelike, all rises step by step with the echelonment between the bottom surface of folded plate and the top surface, and upper end, the lower extreme of folded plate all are provided with the opening moreover, the thickness of boundary beam is 130mm.
Precast beam formula folded plate stair cancel and seal the roof beam, and the component production drawing of patterns is easier, prescribes a limit to 130mm with boundary beam thickness moreover, alleviates component weight, more is favorable to the tower crane hoist and mount.
The purpose of the utility model can also adopt the following technical measures to solve:
furthermore, the folded plate is of a reinforced concrete structure, and a steel mesh is arranged in the folded plate.
Furthermore, the reinforcing mesh is bent into a ladder-shaped ascending shape which is the same as the folded plate, and the reinforcing mesh is distributed on the horizontal part and the vertical part of the folded plate. The folding plate is of a reinforced concrete structure, a reinforcing mesh is arranged in the folding plate, the reinforcing mesh is bent into a ladder-shaped ascending shape which is the same as that of the folding plate, and the reinforcing mesh is distributed over the horizontal part and the vertical part of the folding plate, so that stressed reinforcing steel bars and anti-cracking reinforcing steel bars of the folding plate are uniformly shared, the anti-cracking and stress effects are achieved, and meanwhile, the reinforcing mesh is folded into a ladder shape, so that the rigidity can be improved, and the deformation is not easy.
Further, the thickness of the folded plate is 80mm.
The utility model has the advantages as follows:
the utility model discloses, precast beam formula folded plate stair cancel seals the roof beam, and the component production drawing of patterns is easier, prescribes a limit to 130mm with boundary beam thickness moreover, alleviates component weight, more is favorable to the tower crane hoist and mount.
Drawings
Fig. 1 is a prefabricated beam type folded plate stair of the prior art.
Fig. 2 is the precast beam folded plate staircase of the embodiment.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
embodiment, as shown in fig. 2, an improved structure of a precast beam type folded plate stair comprises boundary beams 1 and folded plates 2, wherein the boundary beams 1 are 130mm thick, the two boundary beams 1 are erected in parallel and oppositely, the folded plates 2 are positioned between the two boundary beams 1, two sides of each folded plate 2 are respectively connected with the corresponding boundary beams 1, the bottom surfaces and the top surfaces of the folded plates 2 are gradually raised in a step shape, openings 3 are arranged at the upper ends and the lower ends of the folded plates 2, and the thickness of the folded plates 2 is 80mm.
The utility model discloses, compare traditional bottom surface and be the stair tread on inclined plane and can reduce the concrete volume of using, also alleviateed weight.
The utility model discloses, folded plate 2 is reinforced concrete structure, sets up reinforcing bar net piece in the folded plate 2, and reinforcing bar net piece is buckled into and is risen the form with the ladder that folded plate 2 is the same, and reinforcing bar net piece spreads over the horizontal part and the vertical portion of folded plate 2 for the atress reinforcing bar and the anti sharing of splitting reinforcing bar of folded plate 2 are unified, play and prevent fracture and atress effect, and reinforcing bar net piece rolls over into the echelonment simultaneously and also can promote rigidity, non-deformable.
The utility model discloses, the cancellation seals the roof beam, and the component production drawing of patterns is easier, inject 1 thickness of boundary beam in 130mm moreover, alleviates component weight, more is favorable to the tower crane hoist and mount.
Taking the height of a 3-meter layer as an example, the original member weighs about 3.6 tons, the optimized member saves concrete by 0.131m3, (about 328kg, accounting for 9.1%), and the part of saving steel bars is not counted.
