Abstract
A concrete load-bearing rainwater grating comprises an outside concrete covering layer doped with indented steel wires, a plurality of reinforcing ribs which are welded to one another in a longitudinally and transversely crossed mode are arranged in an outer frame, the reinforcing ribs constitute a multi-layer stacked structure, the inside space of the outer frame is divided into a plurality of grids through the reinforcing ribs, and the area of each grid is greater than the cross section area of each through hole; the positions, welded to the outer frame, of the reinforcing ribs are close to the bottom of the outer frame, and the middle portions of at least one layer of longitudinal reinforcing ribs and the middle portions of at least one layer of transverse reinforcing ribs are in arch shapes. By the adoption of the structure, the overall strength of the concrete load-bearing rainwater grating is enhanced greatly, and the breaking load of the concrete load-bearing rainwater grating reaches 360KN.
Description
Technical field
The present invention relates to a kind of precast concrete product, particularly a kind of steel fibrous concrete is built the concrete-pouring synthetic manhole forming.
Background technology
The concrete-pouring synthetic manhole that has concreting to form using on market at present, but because downspout strainer has the more through hole for mistake water, adopt the downspout strainer load bearing effect of concreting undesirable.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of concrete bearing downspout strainer, has higher intensity, possesses enough weight capacities.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of concrete bearing downspout strainer, the concrete outer covering layer that comprises doping impression steel wire, in housing, be provided with the reinforcing rib of many crisscross welding, many reinforcing ribs form multilayer laminated structure, described reinforcing rib is isolated into a plurality of grids by the inner space of housing, and the area of grid is greater than the cross-sectional area of through hole;
The position of described reinforcing rib and housing welding, near the bottom of housing, has at least the reinforcing rib of each one deck in length and breadth to have the shape arching upward in middle part.
Described reinforcing rib adopts the vertical structure of three horizontal strokes two.
A kind of concrete bearing downspout strainer provided by the invention, by adopting above-mentioned structure, has significantly improved bulk strength of the present invention, and its failure load has reached 360KN.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is frame construction schematic diagram of the present invention.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Fig. 3 is overall structure schematic diagram of the present invention.
In figure: housing 1, reinforcing rib 2, grid 3, through hole 4.
The specific embodiment
In Fig. 1-3, a kind of concrete bearing downspout strainer, the concrete outer covering layer that comprises doping impression steel wire, in housing 1, be provided with the reinforcing rib 2 of many crisscross welding, many reinforcing ribs 2 form multilayer laminated structure, described reinforcing rib 2 is isolated into a plurality of grids 3 by the inner space of housing 1, and the area of grid 3 is greater than the cross-sectional area of through hole 4;
The position of described reinforcing rib 2 and housing 1 welding, near the bottom of housing 1, has at least the reinforcing rib 2 of each one deck in length and breadth to have the shape arching upward in middle part, and the reinforcing rib 2 of each one deck in length and breadth is above arch in this example.The structure of reinforcing rib thus, the stressed position that is dispersed to housing 1 when middle part, and housing 1 is subject to installing basic clamping, thus improved bulk strength of the present invention.
In the structure of optimizing, as shown in Figure 1, described reinforcing rib 2 adopts the vertical structure of three horizontal strokes two.Through test of many times, reinforcing rib adopts the vertical structure of three horizontal strokes two comparatively balanced between load bearing stength and result of use.
Claims (2)
