Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a member for covering a joint part of an underground structure formed by joining steel panels.

Underground structures such as basements that are partially or completely buried underground have been attracting attention recently because they allow effective use of land, have excellent sound insulation and constant temperature properties, and are effective as disaster prevention shelters. .

Such underground structures must be able to withstand a certain amount of earth pressure, and for this reason, reinforcement is placed within the formwork, concrete is poured, and a waterproof finish is applied. However, in the case of concrete pouring, construction cannot be carried out in rainy weather, construction is difficult in cold regions in winter, the construction itself requires multiple steps, a long period of time is required for the concrete to cure, and furthermore, even after finishing, it is difficult to perform construction in cold regions. It can take up to a year to dry. The biggest drawback is that concrete underground structures are difficult to waterproof, and it is extremely difficult to find and repair water leaks.

For this reason, underground structures have recently been assembled by joining a plurality of steel panels with bolts or the like. In this case, a waterproof seal is interposed at the joint to prevent water from leaking from the joint. In this way, when an underground structure is buried underground, earth pressure acts on the joints of the panels,
Joints open and leak easily.

The present invention was made in order to improve the above-mentioned problem of underground structures made by joining steel panels, and it can be installed from inside the underground structure by utilizing the space between the panels to form a waterproof seal. It is an object of the present invention to provide a joint cover that can complete the treatment and also disperse the earth pressure acting on the joints of panels.

In order to achieve this object, the present invention has a flat pressure receiving part having a width and length that can cover the joints between panels, and an upright part vertically installed near both ends of this pressure receiving part. The gist is that a bent portion is formed to form a joint cover, and this cover is attached to the panel with bolts so as to straddle the joints between the panels.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view of a joint cover 1 according to the present invention, cut in the width direction. Standing parts 3, 3 are vertically provided in a direction substantially perpendicular to both tips of 2, and these rising parts 3, 3 are further folded inward from the middle part to form bent parts 4, 4, and the cross section as a whole is approximately channel-shaped. I am trying to make it so that

Bolt insertion holes 5 are formed in the bent portions 4, 4 at regular intervals.

FIG. 2 shows a part of the underground structure before installing the joint cover 1, and the underground structure is made up of a plurality of steel panels, for example, a wall panel 6 and a roof panel 7 have a space 8. The H-beams 9 and 10, which are protruding from each other, are butted against each other and joined together via a gusset plate.

FIG. 3 shows a cover 1 according to the present invention attached to the above joint part.
It is a perspective view showing a state in which the cover 1 is attached, and the bent parts 4, 4 of the cover 1 are superimposed on each panel via a waterproof seal S on the end of the roof panel 7 facing the bent part of the wall panel 6, Bolt 1 from indoor space 8
1, 11... are inserted, and the bent portions 4, 4 and each panel 6, 7 are screwed together with the bolts. Thus, the cover 1 is attached so as to straddle the panel 6 and cover the space 8.

In this way, as shown in the cross section of FIG. 4, the cover 1 is attached to the joints of each panel, such as the wall panel 6 and the roof panel 7, and the floor panel 12 and the wall panel 6.

5 and 6 show other embodiments of the cover, of which the cover 13 shown in FIG. Therefore, the standing portion 16 and the bending portion 1
7, and the cover 18 shown in FIG. 6 has a pressure receiving part 19, an upright part 20, and a bent part 21 formed by welding a U-shaped member to a steel plate. It is.

Furthermore, bolt insertion holes are formed in each of the bent portions 17 and 21 at appropriate intervals.

Next, to describe the above-mentioned cover action, by attaching the cover so as to straddle the joints with spaces between each panel, the spaces 8, 22, and 2 of each joint between the panels can be viewed from the indoor side.
Since a wrench, spanner, etc. can be inserted into 3 and 24, butt joints of H-beam steel can be made extremely easily, and earth pressure does not act directly on the joint, but instead acts on the cover. The earth pressure acting on the panel is distributed to the bent portions 4, 4 and transmitted to each panel. Furthermore, since the waterproof seals S, S, . . . are interposed between the folded portion 4 of the cover and the panel, earth pressure acts on the waterproof seals S in the vertical direction, resulting in improved sealing performance.

As explained above, according to the present invention, the structure of the cover that covers the joint of an underground structure formed by joining a plurality of steel panels includes a flat pressure receiving part of a size that can cover the joint, It shall consist of a standing part bent at right angles from both sides of the pressure receiving part and a bent part bent inward from this standing part, and the cover shall be attached from the indoor side using the space formed at the joint part. This makes it possible to perform waterproof sealing of underground structures extremely easily and completely.

In addition, since this cover is installed so as to straddle the joint, it is possible to disperse the earth pressure acting on the joint, and furthermore, the above-mentioned bent part and the panel can be joined via a waterproof seal. Since earth pressure acts on the waterproof seal in the right angle direction, it has many effects such as increasing waterproofness.
