Abstract
The utility model discloses a prestressed prefabricated reinforced concrete plate for a retaining wall, which comprises a concrete plate and a prestressed bar, wherein the concrete plate presents a Z shape, the middle lower part of the concrete plate is provided with a thickening layer and the prestressed bar is embedded in the thickening layer. The utility model has the advantages of reasonable structure, light weight, capability of factory operation, low cost, beautiful appearance, etc.
Description
Technical field:
The utility model relates to the Retaining wall plate in a kind of municipal administration, highway, railway and the large scale industry engineering.
Technical background:
The traditional form of retaining wall, stock retaining wall is gravity, breast wall type etc., and the type retaining wall causes material usage big greatly because of the cross section, and is uneconomical.And build by laying bricks or stones at the employing scene or on-the-spot formwork construction, is subjected to the restriction of place and weather conditions, long construction period.
Summary of the invention:
The purpose of this utility model is: but a kind of batch production production rational in infrastructure, in light weight, cost prestressing force prefabricated reinforced concrete Retaining wall plate low, attractive in fashion are provided, to solve the problem that prior art exists.
The utility model is to constitute like this: it comprises concrete slab (1), and presstressed reinforcing steel (2), concrete slab (1) are " Z " shape, and there is thickening layer (3) middle and lower part of concrete slab (1), and presstressed reinforcing steel (2) is embedded in the thickening layer (3).
The height of thickening layer (3) is 1/3～1/2 of a concrete slab (1).
The utility model compared with prior art has the following advantages:
1, conversion rigidity in cross section is big, structure stress has a clear superiority in, material is economized.
2, adopt prestressing technique, according to its purposes, apply prestressing force at suitable position, make it to meet the loading characteristic of structural element, the member section reduces significantly, and deadweight alleviates significantly, saves great amount of investment, remarkable in economical benefits.
3, adopt standard block prefabricated, batch machining is concentrated in batch production, and on-site consolidation is flexible, and cost is low, efficient is high, can shorten the construction period 50%, avoided building by laying bricks or stones, formwork, a large amount of site work such as cast-in-place, and weather is less to the influence of constructing.
When 4, being used for the industrial premises stock retaining wall, the intercolumniation that is arranged in factory building is arranged, does not occupy the windrow space in the factory building, has guaranteed the storage capacity of windrow to greatest extent.
When 5, being used for retaining soil (material) wall, being suitable for of retaining wall highly can be increased to 15M, and at plate 1/3～1/2 from the local thickening of degree scope inner member and apply prestressing force, the maximal bending moment bottom effectively offsetting.
6, utilize the moulding and the spatial variations of member itself, beautified building.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is user mode figure of the present utility model.
The specific embodiment:
Embodiment of the present utility model: form " Z " shape concrete slab (1) with concrete casting, there is thickening layer (3) at 1/2 place of concrete slab (1), and presstressed reinforcing steel (2) is embedded in the thickening layer (3).
Claims (2)
1. prestressing force prefabricated reinforced concrete Retaining wall plate, it comprises concrete slab (1), and presstressed reinforcing steel (2) is characterized in that: concrete slab (1) is " Z " shape, there is thickening layer (3) middle and lower part of concrete slab (1), and presstressed reinforcing steel (2) is embedded in the thickening layer (3).
2. prestressing force prefabricated reinforced concrete Retaining wall plate according to claim 1 is characterized in that: the height of thickening layer (3) is 1/3～1/2 of a concrete slab (1).
