steel mold structure

Abstract

The invention discloses a steel mold structure. The structure comprises a lower old, the lower mold comprises a box body, an opening is formed in the upper end, the horizontal section is rectangular, a steel rib mounting frame defined by vertical plates on the four faces and being of a rectangular frame structure is arranged in the box body, the long side of the lower mold corresponds to the long side of the steel rib mounting frame, multiple mounting grooves formed through sinking are evenly distributed in the upper end of the long side of the steel rib mounting frame, a frame body is arranged above the steel rib mounting frame in a right facing manner, the frame body is defined by the vertical plates on the four faces, the horizontal cross section of the frame body is consistent with that of the steel rib mounting frame, the lower end of the long side of the frame body right faces positioning grooves formed in the mounting grooves in a sinking manner, the mounting grooves and the positioning grooves are in one-to-one abut joint to form a steel rib mounting space matched with the outer circle of steel ribs used for forming a rain perforated strainer; and the lower mold is further provided with a steel rib positioning mechanism and a steel rib anti-floating mechanism. The steel mold structure has the beneficial effects of being simple in structure, capable of being repeatedly used and low in cost.

Description

technical field [0001] The invention relates to a pouring mold for building rainwater grates; in particular, it relates to a steel mold structure for pouring rainwater grates. Background technique [0002] The rainwater outlet refers to the facility for the pipeline drainage system to collect surface water. It is generally installed in blocks, squares and streets as the entrance for surface runoff rainwater to flow into the sewage system to prevent rainwater from flooding the road or causing water accumulation in roads and low-lying areas to hinder traffic. or damage the road. There is usually a rainwater grate at the gully, which can filter and retain debris in the water flow, and at the same time prevent vehicles and pedestrians from falling into the gully. There are mainly two types of rainwater grate: flat grate and vertical grate. The most commonly used is the flat grate. The flat rainwater grate is usually installed on both sides of the road and needs to bear the grav...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned anti-compressive rainwater grate is equipped with a steel skeleton, so compared with the general flat grate type rainwater grate, the bearing capacity has been improved to a certain extent, but there are still the following defects: 1. When manufacturing rainwater grates, it is necessary to choose different diameters. Steel bars also need to be set to different lengths and welded to each other, which makes the processing complicated and takes a long time

2. After processing the steel skeleton, wrap the composite material on the steel skeleton and reserve leaking holes to reduce the construction efficiency, and use composite materials to increase the construction cost

3. Due to the structural form of the steel skeleton itself, the steel skeleton can only be applied to the flat grate type rainwater grate, and it is not applicable to the vertical grate type rainwater grate

4. There is no specific processing template for processing, and it can only be processed separately each time, resulting in poor construction efficiency and high cost
