AI Technical Summary

Technical Problem

Conventional cover members for drainage channels in buried structures are heavy, costly, and inefficient in rainwater collection due to wasteful central parts that are not used for water drainage.

Method used

A cover member design featuring beam members with a shorter span and a main member that crosses these beam members, reducing the weight and material costs while enhancing rainwater collection efficiency by minimizing wasteful central parts.

Benefits of technology

The design achieves a lighter overall weight, reduces manufacturing costs, and improves rainwater collection efficiency by minimizing unused central parts, thus optimizing the structure's functionality and cost-effectiveness.

Abstract

To provide a lid member and a method for installing the lid member, wherein the lid member can reduce a wasteful portion not used for collecting rainwater and the like, reduce the entire weight of the lid member, and reduce the manufacturing cost.SOLUTION: A lid member 500 placed on a lid hanging part 821 on both sides of a buried structure 800 comprises: a pair of beam members 300 that are spanned between the lid hanging part 821; and a lid body part 400 having a main member 410 that spans the beam members 300 so as to intersect the beam members 300, wherein a length L3 of the main member 410 in a longitudinal direction is shorter than a length L2 of the beam member 300 in the longitudinal direction.SELECTED DRAWING: Figure 4

Claims

1. A lid member to be placed on the lid hanging portions on both sides of the buried structure, A pair of beam members arranged on the upper side of the lid hanging portion so as to span between the lid hanging portions; a lid body portion having a main member that is hung across the beam member so as to cross the beam member, A cover member, characterized in that the length of the main member in the longitudinal direction is shorter than the length of the beam member in the longitudinal direction.

2. The cover member according to claim 1 , wherein the cover body portion is detachably fixed to the beam member.

3. 3. The cover member according to claim 1, wherein the beam member is configured by assembling two substantially U-shaped members so as to embrace each other.

4. The generally U-shaped member is composed of an outer member and an inner member, The upper wall and the lower wall of the outer member are respectively overlapped and assembled to the upper wall and the lower wall of the inner member, The closure of claim 3 , wherein the outer member and the inner member have non-overlapping portions that do not overlap each other.

5. 5. The lid member according to claim 1, wherein the beam member is provided with a fixing member for fixing the lid member to an adjacent lid body.

6. A method for installing the cover member according to claim 5 on a buried structure, comprising the steps of: one of the lid bodies adjacent to the lid member is installed on the buried structure prior to the lid member and the other lid body; Next, the lid member is installed on the buried structure such that one fixing member of the lid member is inserted under the lower surface of the one lid body; Next, the other lid body is installed on the buried structure so as to cover the other fixing member of the lid member from above, An installation method characterized in that the fixing members extending laterally from both sides of the lower end of the lid member are placed against the undersides of each adjacent lid body.
