Abstract

The utility model discloses a plate-folding type material-stopping wall for casting reinforced concrete, belonging to the technical field of civil engineering structure, specifically belonging to the material-stopping wall of a warehouse for high-capacity bulk materials. Folded plate structure is adopted, the horizontal section of the material-stopping wall (2) can be in a groove shape or a V shape, and a folding angle alpha is between 15 degrees and 75 degrees. The optimum horizontal section is the groove shape, and the optimum folding angle alpha is 45 degrees. The plate-folding type material-stopping wall for casting reinforced concrete is characterized in that anti-horizontal side shift rigidity is large, the plate-folding type material-stopping wall for casting reinforced concrete has favorable adaptability for the material-stopping wall with high height, the structural stress of the folded plate structure has large advantage due to the large rigidity of folded plate, thus the wall has small thickness and light self-weight, and a large amount of investments can be saved. The plate-folding type material-stopping wall for casting reinforced concrete is suitable for the material-stopping walls of the warehouse for various high-capacity bulk materials, retaining walls and ridges in civil work.

Description

Flap shaped steel reinforced concrete stock retaining wall

Affiliated technical field

The utility model belongs to the civil engineering structure field, belongs to the stock retaining wall in big capacity bulk material storage storehouse specifically.

Background technology

In the industrial premises design, the design of storing the stock retaining wall in storehouse for big capacity bulk material the most simply is to adopt the gravity stock retaining wall, problems such as the weight balancing windrow horizontal thrust of promptly utilizing body of wall self was toppled to body of wall produces, slippage, the section of this gravity stock retaining wall must be enough big, therefore the constructional materials consumption is many, the body of wall floor space is big, and uneconomical reasonable.Along with industrial expansion, the requirement for height of bin stock storehouse windrow is more and more higher, and therefore design has proposed more Gao Gengxin requirement to stock retaining wall, and people have proposed various different designs schemes for this reason, it is a kind of most economical reasonable to attempt to design, the stock retaining wall in both artistic and practical storehouse in bulk.What employing was more in designing at present is steel concrete cantilevered stock retaining wall (Fig. 1, Fig. 2) and two kinds of schemes of steel concrete counterfort formula stock retaining wall (Fig. 3, Fig. 4).Because the more and more large-scale change of industrial production, various raw material consumptions are more and more, bulk cargo storage storehouse feed height constantly increases, the horizontal direction lateral pressure of material increases, the lateral deformation stiffness of design stock retaining wall requires increasing, above-mentioned two kinds of structural shapes have existed significant disadvantages: the cantilevered stock retaining wall is straight line on horizontal plane, so the anti-horizontal endurance and stiffness of stock retaining wall is little, be difficult to satisfy distortion and requirement of strength under the active force of material horizontal direction, must satisfy by the cross section and the arrangement of reinforcement of thickening stock retaining wall, cause very big waste thus; Steel concrete counterfort formula stock retaining wall is compared with steel concrete cantilevered stock retaining wall, and the thickness of wall reduces to some extent, but owing to the horizontal force of respectively striding intercolumniation is delivered on the counterfort, counterfort is stressed very big, and the section of counterfort and arrangement of reinforcement are also very big, and cost is higher.In addition, above-mentioned two kinds of patterns have all occupied the storage capacity that windrow has been reduced in more space in the factory building.Counterfort formula stock retaining wall also because counterfort is bigger, has influence on the operation of material grasping bucket, causes dead material district.

The Chinese patent literature storehouse finds no the application scheme of closing big capacity bulk material storage storehouse stock retaining wall civil engineering structure by retrieval.

Summary of the invention

It is a kind of rational in infrastructure, handsome in appearance, cheap that the purpose of this utility model is to provide, the stock retaining wall in economic and practical big capacity bulk material storage storehouse.

For identical materials, the rigidity of folded form material and stability are much larger than the rigidity and the stability of flat type material.According to this principle, stock retaining wall of the present utility model adopts folded structure: the horizontal section of stock retaining wall 2 is designed to V-arrangement and also can be designed as flute profile, and the horizontal section optimum shape of this folded structure is a flute profile.The stock retaining wall of folded structure is not because be dull and stereotyped stressed under the horizontal applied force of material, be that flap is stressed, the conversion rigidity of flap is very big, stressing conditions is good, so design feature of the present utility model is that anti-horizontal endurance and stiffness is big, so the section of stock retaining wall 2 can be made very thinly, thereby reach the effect of saving constructional materials.

According to the actual numerical value of span between the factory building column 1, for guaranteeing the lateral deformation stiffness of stock retaining wall 2, stock retaining wall 2 can be designed as repeatedly folding by result of calculation, and its angle folding α can select 15～75 ° according to circumstances, and best angle is 45 °.

Flap type stock retaining wall is compared with cantilevered stock retaining wall, counterfort formula stock retaining wall, makes full use of the big design feature of flap rigidity, and higher stock retaining wall is had good compliance; Folded structure is because convert the rigidity of rigidity much larger than flat board, and structure stress has very big advantage, so the thickness of stock retaining wall is little, from heavy and light, can save great amount of investment, remarkable in economical benefits; Flap is arranged between the column of factory building, does not occupy the windrow space in the factory building, has guaranteed the storage capacity of windrow to greatest extent; Flap type stock retaining wall structure is light and handy, handsome in appearance, and the effect of beautifying constructure is arranged.

The utility model is applicable to the stock retaining wall in various big capacity bulk material storages storehouse, the retaining wall in the various civil workss, Bao Kan.
