Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for closing an end of a deck plate. More specifically, the present invention relates to a closure that can very easily and reliably close an end opening of a deck plate hooked on a laying member such as a beam, and that can be manufactured at low cost.

[0002]

2. Description of the Related Art In a floor plate method of a reinforced concrete building, a method is adopted in which a deck plate formed into a trapezoidal corrugated shape is laid over a beam of the building in a bridging manner, and concrete is poured on the deck plate. There are many.

Since the deck plate is formed in the shape of a trapezoidal corrugated plate, an opening corresponding to the unevenness of the corrugated plate is formed at an end hooked on a beam or the like. For this reason, before pouring concrete, it was necessary to work to close the opening by welding a plate-like closing member or the like. However,
This work required a great deal of labor and cost, which not only shortened the construction period but also increased construction costs.

[0004] In order to solve the above problem, for example, there is provided an obturator for closing an end opening of a deck plate such as that disclosed in Japanese Utility Model Publication No. 35809.

In the closing device, an upper piece extending at a right angle is provided on an upper portion of a plate-shaped main body to be attached to an end opening, and the upper piece is attached to an upper surface of an edge of the deck plate via a double-sided adhesive tape. It is configured to be worn.

[0006] Since the closing device can be mounted simply by peeling off the release paper of the double-sided adhesive tape and attaching it, the mounting operation is extremely simple, and the construction period and cost can be reduced.

[0007]

The upper surface of the deck plate is very dirty because the worker walks or works. For this reason, in order to stick a double-sided adhesive tape as described in the above publication, the sticking surface must be cleaned. In particular, when there is oil stains or the like, it is not possible to attach the adhesive tape with sufficient strength simply by wiping the surface.

Further, once the adhesive tape once adhered is peeled off, the adhesive strength is greatly reduced. For this reason, when correcting an obstruction device which is erroneously attached, the adhesive tape must be replaced.

Further, it is very difficult to hold the closing member in the closed state in which the closing member is in contact with the edge of the deck plate by the adhesive force of only the upper piece, and a gap is easily formed between the closing member and the deck plate. In addition, the obturator may come off or the clearance may increase due to the flow during the casting of the concrete.

The present invention has been conceived in view of the above-mentioned circumstances, and solves the above-mentioned conventional problems, can be mounted very easily, and depends on the condition of the deck plate surface and the like. It is an object of the present invention to provide a deck plate that can secure a high mounting strength without any trouble.

[0011]

Means for Solving the Problems To solve the above problems, the present invention takes the following technical means.

[0012] An end opening closing device for a deck plate according to the present invention is a flat closing plate portion which is attached so as to cover an end opening of a deck plate laid on a laying member, and the closing plate portion. And an engaging portion extending from the edge or the attachment surface of the deck plate and elastically abutting on the vicinity of the edge of the deck plate to hold the closing plate portion in the attached state.

The material for forming the end opening closure according to the present invention is not particularly limited. For example, the closing plate portion and the engaging portion can be integrally formed of resin. Further, the closing plate portion and the engaging portion may be formed of different materials. For example, an engaging portion formed of a metal spring plate may be joined to a closing plate portion formed of a resin plate by welding or the like.

The closing plate portion is formed to be slightly larger than the shape of the opening end portion so as to be attached to the end opening of the deck plate. The size of the end opening is not particularly limited, but may be any size as long as the holding portion can be extended from the edge or the attachment surface. Further, in order to cope with different end opening shapes and sizes, it can also be formed to a certain degree. Further, claim 9
As in the invention described in (1), a plurality of end openings can be formed so as to be closed at a time.

Various methods can be adopted for the engaging portion as long as it can hold the closing plate portion in an attached state using elastic force.

For example, as in the invention as set forth in claim 2, at least one pair of elastic clamping members which elastically clamp the engaging portion from the inner surface side and the outer surface side of the edge of the deck plate are closed. It can be formed by extending from the edge of the plate portion or the adhered surface.

By providing the elastic holding member, it becomes possible to hold the closing plate portion in an attached state with a very simple configuration. Further, since the adhered state is maintained by the elastic force, the detachment is easy.

The configuration and arrangement of the elastic clamping member are not particularly limited, and may be configured and arranged so that elastic force can be applied while the deck plate is sandwiched. Further, the elastic clamping members on the inner surface side and the outer surface side do not necessarily need to be provided to face each other. What is necessary is just to comprise so that the elastic clamping member of an inner surface side and an outer surface side may cooperate and can pinch the edge of the said deck plate. There is no particular limitation on the portion where the elastic holding member is held, and the elastic holding member can be provided on the upper edge or the side edge depending on the shape of the deck plate or the like.

Further, the form of the elastic holding member is not particularly limited, and it can be formed in a plate-like or rod-like shape so as to extend to the edge or the surface to be adhered. Further, one plate-like elastic holding member may be provided on the outer surface side, and a plurality of projecting elastic holding members may be provided on the inner surface side.

The elastic holding member may be any member that can be held on the end of the deck plate by elastic force. Therefore, the elastic force may be applied only from the clamping members on one of the inner surface side and the outer surface side.

For example, as in the invention described in claim 3 of the present application, the elastic holding member on the outer surface side is formed to extend along the upper edge of the closing plate portion, and the upper edge portion of the deck plate. An engagement edge portion that is brought into contact with the outer surface, wherein the elastic clamping member on the inner surface side is formed so as to extend opposite to the engagement edge portion and is brought into contact with the inner surface of the deck plate; A form of two or more elastic clamping projections can be adopted.

Since the engaging edge is attached in a state of contacting the outer surface of the upper edge of the deck plate, it does not easily come off even if the operator steps on the obturator with the leg. Further, since there is almost no gap between the upper edge portion of the deck plate and the inner surface of the closing member, the resistance to the flow when the concrete is poured is increased.

According to the invention described in claim 4 of the present application, the elastic holding member on the inner surface side and the elastic holding member on the outer surface side
At least a base end portion is formed so as to extend with a gap large enough to accommodate the end portion of the deck plate.

The above-mentioned base end portion is a portion of the closing plate portion on the attachment surface. It is desirable that the inner surface (adhered surface) of the closing plate portion is brought into contact with the edge of the end opening without any gap. Therefore, the gap between the base ends of the elastic holding members is such that the edge of the deck plate can be brought into contact with the adhered surface of the closing plate portion, that is, the gap is large enough to accommodate the end portion of the deck plate. Is set. In particular,
What is necessary is just to set larger than the thickness of a deck plate. Also, to be able to accommodate deck plates of different thickness,
The gap can be set.

On the other hand, in a portion other than the base end portion, the elastic holding member needs to elastically contact the deck plate. For this reason, they are arranged facing each other with a gap smaller than the thickness of the deck plate, or are arranged in a crossed state. Thus, the holding member can be held on the deck plate while the edge of the deck plate is in contact with the inner surface of the closing plate.

In the invention described in claim 5 of the present application, an introduction tongue for guiding the edge of the deck plate is provided at the tip of the elastic holding member on the inner surface side.

The higher the elastic clamping force, the greater the resistance during mounting. The obturator according to the present claim,
The introduction tongue is pressed against the upper edge of the deck plate from below, and the elastic holding member can be pushed and opened via the introduction tongue so as to be attached. For this reason, a large elastic clamping force can be obtained, and attachment of the obturator can be performed extremely easily.

The shape and number of the introduction tongue are not particularly limited, and may be constituted by extending the tip of the elastic holding member in the same shape. Also, the cross-sectional shape can be set to be easily elastically deformed so that the end of the deck plate can be guided with a small force.

The invention described in claim 6 and claim 7 of the present application does not hold the obturator by sandwiching the edge of the deck plate, but forms the end formed by the deck plate or the member on which the deck plate is laid. The obturator is held by the force pressing the inside of the wall of the opening outward.

According to a sixth aspect of the present invention, there is provided an elastic abutment in which the engaging portion is elastically abutted on inner surfaces of opposite edges of an end opening formed by the deck plate and the deck plate laying member. It is configured with members.

When attaching the obturator, the elastic contact member is pushed into the end opening while being forcibly elastically deformed. The elastic member is used to hold the obturator in the attached state.

By constituting the end openings so as to elastically abut against the inner surfaces of the opposite edges, it is possible to balance the forces acting vertically. This allows
The closing device can be held only by the elastic contact member.

For example, as in the invention as set forth in claim 7, the elastic contact member is provided with an elastic contact member elastically contacting the inner surface of the upper edge portion of the deck plate and an elastic contact member elastically contacting the upper surface of the laying member. It can be configured to include an elastic contact member that contacts.

When the end opening has a trapezoidal shape, it suffices to elastically contact the inner surfaces of the upper and lower end openings which are opposed to each other in parallel. Installation work can also be easily performed. The upper and lower elastic contact members can be separately formed and fixed to the inner surface of the closing plate portion. Further, the upper and lower elastic contact members can be integrally formed, and the intermediate portion can be fixed directly to the inner surface of the closing plate portion or via a support member or the like.

According to the invention described in claim 8 of the present application, the engaging portion abuts on the inner surface of the upper edge of the deck plate to elastically urge the closing plate portion attached to the end opening downward. It is configured to include a contact member, and is configured to press and lock the lower edge of the closing plate portion against the surface of the deck plate laying member.

According to the present invention, the elastic force generated by the elastic contact member abutting against the inner surface of the upper edge portion of the deck plate is supported by using the lower edge of the closing plate portion, and the closing member is covered. It is kept in the wearing state. Usually, the end of the deck plate is hung on a laying member such as a beam in a bridging manner. Therefore, the adhered state can be maintained by elastically pressing the lower edge of the closing plate portion along the end opening onto the upper surface of the laying member.
