Abstract
The utility model provides a novel prefabricated staircase's technical scheme, including the step, be provided with on the step and mark time characterized by: be provided with light block of material in the inside of marking time, outside encirclement of light block of material have the concrete topping, be provided with reinforced frame in the concrete topping, just reinforced frame stretch into in the step, the integrative pouring of concrete topping and step. The prefabricated staircase of this scheme has alleviateed the dead weight, the hoist and mount of being convenient for, material saving, reduce cost, reduction energy consumption to the mesh that alleviates whole building weight has been realized.
Description
Technical field
The utility model relates to construction engineering technical field, a kind of with ribs and the novel precast stair of filling with light material.
Background technology
In the prior art, known technology is assembled architecture owing to the features such as the cycle is short, resource consumption is few, environmental protection have obtained increasingly being widely applied.In assembled architecture, precast stair is important vertical means of transportation and safe escape passage, and use at present is all the precast stair of whole concrete making mostly, and such precast stair weight is relatively big, is unfavorable for transport and assembling, and cost of manufacture is high.Therefore, save material for playing assembled architecture greatly, reduce cost, the feature of minimizing energy consumption, especially solve regular spans to cause more greatly conducting oneself with dignity the problem that bigger stair lift by crane difficulty in construction, it is necessary precast stair is optimized design, is desirably to obtain safety, light novel precast stair.
Summary of the invention
The purpose of this utility model, it is simply that for the deficiency existing for prior art, and provide the technical scheme of a kind of novel precast stair, the precast stair of the program, alleviates deadweight, it is simple to lifting, save material, reduce cost, minimizing energy consumption, and and then achieve the purpose alleviating entire building weight.
This programme is achieved by the following technical measures: a kind of novel precast stair, including gangboard, gangboard is provided with and marks time, the feature of this programme is: be internally provided with light material block mark time, the outside encirclement of described light material block has concrete topping, in concrete topping, it is provided with reinforced frame, and described reinforced frame extend in gangboard, described concrete topping and gangboard one cast.
Described gangboard is provided with ribs, and described ribs is arranged on gangboard lower surface.Described ribs is dentation distribution.
Described ribs is strip, and ribs quantity is more than or equal to 2.
Reinforced frame it is provided with in gangboard.
The beneficial effect of this programme can be learnt according to the narration of such scheme, owing to there being light material block in this scenario, so can alleviate the weight of precast stair, it is easy to lifting, also a saving concrete amount, it is achieved that energy-conservation purpose, light material can use styrofoam；And gangboard and concrete topping one cast, it is ensured that the intensity of precast stair；In concrete topping, there is reinforced frame, this ensure that the intensity marked time, and the reinforced frame in concrete topping extend in gangboard, further enhancing the connection of pedal and gangboard；In gangboard, there is reinforced frame, enhance the globality of gangboard, meet anchoring requirements；Described gangboard is provided with ribs, meets the bearing capacity of stair and the normal requirement used.As can be seen here, this utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent from.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model detailed description of the invention.
Fig. 2 is the sectional view of Fig. 1.
Fig. 3 is the structural representation of gangboard.
In figure, 1 for marking time, and 2 is gangboard, and 3 is concrete topping, and 4 is light material block, and 5 is ribs, and 6 is reinforced frame.
Detailed description of the invention
For the technical characterstic of this programme can be clearly described, below by a detailed description of the invention, and combine its accompanying drawing, this programme is illustrated.
By accompanying drawing it can be seen that the novel precast stair of this programme, including gangboard 2, gangboard 2 is provided with and marks time 1, mark time 1 be internally provided with light material block 4, the outside encirclement of described light material block 4 has concrete topping 3.In concrete topping 3, it is provided with reinforced frame 6, and described reinforced frame 6 extend in gangboard 2, described concrete topping 3 and gangboard 2 one cast.Reinforced frame 6 it is provided with in gangboard 2.
Described gangboard 2 is provided with ribs 5, and described ribs 5 is arranged on gangboard 2 lower surface.Described ribs 5 is distributed in dentation.Described ribs 5 is strip, and ribs number 5 amount is more than or equal to 2.
During use, when gangboard 2 span is 5.16m, gangboard 2 thickness of band ribs 5 position is 250mm, can meet bearing capacity and normally use requirement, now, the gangboard 2 without ribs position is used for stress smaller part position, thickness 80mm, concrete topping 3 thickness takes 50mm.The application scheme carries out conceptual design according to stair loading characteristic, and is met the bearing capacity of specification by arrangement of reinforcement calculating and normally used requirement.More conventional precast stair, the precast stair of the application scheme, deadweight minimizing 37% when having reached lifting, fit up after conduct oneself with dignity minimizing 33%, simultaneously cost reduce 14% design object, efficiently solve the general hanging device of precast stair simultaneously and lift difficult problem.
Claims (5)
