BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a building equipment sleeve installed on a floor of a building for attaching a duct used for air conditioning or inserting a pipe.

[0002]

2. Description of the Related Art Generally, when building a building or the like, a sleeve for building equipment for installing ducts used for air conditioning or piping is installed on the floor of the upper floor, and when it is installed, it is formed in a wave shape. A deck plate made of a steel plate is stretched, a sleeve is placed on the plate, and in this state, the deck plate is used as a formwork to pour concrete into the floorboard. With the sleeve embedded in the floor board in this manner, a through hole is formed in the deck plate along the lower end surface of the sleeve by melting or the like, and a duct is attached to the sleeve. However, in the above, since the sleeve is left on for a certain period of time from installation on the floor to installation of the duct on it,
In order to prevent the risk of workers involved in building the building falling into the sleeve, a lid plate with a simple structure that has a bent piece on the periphery is conventionally fitted on the upper end surface of the sleeve. Was.

[0003]

However, according to the conventional structure, since the lid plate is separate from the sleeve, the sleeve is installed on the floor and the deck plate is cut to open the through hole. After the completion of the work, the work of fitting the cover plate to the sleeve may often be forgotten, or the cover plate may easily move on the upper end surface of the sleeve, and the sleeve may be left open. However, there was an inconvenience that it was inferior in terms of safety.

[0004]

Therefore, in order to ensure safety, the present application provides inward flanges for mounting ducts along the upper peripheral edge and the lower peripheral edge, respectively, and mounts the mounting holes on the flanges at a constant pitch. And a sleeve body having a size that closes the opening of the sleeve body, and on one side thereof,
And a lid provided with a hinge having a pair of mounting holes having the same pitch as the mounting hole, wherein the hinge is detachably mounted on a flange along one side of the sleeve body through the mounting hole. The lid body is attached to the lower flange of the sleeve body so that the lid body can be undulated via a hinge, and the length of the lid body in the upright direction is formed longer than the height of the sleeve body, and The sleeve body is colored yellow and the lid is colored red.
Further, in order to maintain the standing state of the lid body, the lid body is provided with a holding means for holding the standing state of the lid body with respect to the sleeve main body, if necessary.

[0005]

Thus, for example, after constructing the floorboard, the lid is opened during the work of forming the through hole in the deck plate in accordance with the sleeve body. In this case, the length of the lid in the upright direction is made longer than the height of the sleeve body, and
When the lid is red, a part of the lid protrudes from the upper end surface of the sleeve body, so that the dangerous color red can be seen from the outside, so that the opening state of the sleeve body can be easily confirmed. Further, after the above-described work of opening the through hole, the lid is laid down to close the opening surface of the sleeve body. Furthermore, when attaching the duct to the sleeve body,
The hinge is removed from the sleeve body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present application will be described in detail with reference to the drawings. The duct main body 1 is made of a steel material having an L-shaped cross section and is framed in a rectangular shape. In this example, the lower frame member 2b is provided so as to be located slightly above the lower edge of the steel plate. The duct body 1 having the rectangular tube shape formed in this way has upper and lower peripheral edges. The upper and lower flanges 3a and 3b which project inwardly are provided with mounting holes 4a and 4b which match the mounting holes of a constant pitch arranged on the flange b provided on the duct B described later.

A lid 5 attached to the duct body 1
Is substantially the same as the plane formed by the inner edges of the flanges 3a to 3b, or, as shown in the figure, is made of a steel plate having a length in the front-rear direction slightly longer than the front-rear width dimension of the flat surface. A hinge 7 having a long attachment piece 6 is fixed to the left and right positions of the edge portion by, for example, welding, and the attachment hole 4 is attached to the attachment piece 6 in the longitudinal direction.
A pair of mounting holes 8 having a pitch equal to the pitch P of b and 4b are provided. In the lid body 5 configured as described above, the mounting pieces 6 having the hinges 8a and 8a are attached to the lower collar piece 3b.
By fitting the pair of mounting holes 4b, 4b arranged in the above, and fastening them with bolts and nuts 9, they can be mounted in the sleeve body 1 so as to be able to rise and fall freely.

A hole 10 for hand-holding is formed in the left and right positions near the other edge of the lid 5 in the front-rear direction, and the lid 5 stands at the central position when the lid 5 stands up. A locking piece 11 that locks with the mounting hole 4a of the upper flange 3a and holds the upright state is provided so as to be vertically rotatable. Further, the receiving pieces 12 of the lid 5 are provided at the left and right positions of the lower flange 3b. In the above, the sleeve body 1 is painted with yellow paint, and the lid 5 is painted with red paint.

When the sleeve body 1 is embedded in the floor A and then a through hole corresponding to the lower surface of the sleeve body 1 is opened in the deck plate a, as shown in FIG.
As shown by the phantom line, the lid 5 is erected. In this standing state, the locking piece 11 is attached to the upper flange 3a of the sleeve body 1.
It is held by being locked in the mounting hole 4a of the above, and in this state, the through hole is opened in the deck plate. In this standing state, since the upper portion of the lid plate 5 which is reddish protrudes from the upper end surface of the sleeve body 1, it can be easily confirmed from the outside that the sleeve body 1 is in the open state.

When the sleeve body 1 is not used, as shown by the solid line in FIG. 2, the lid body 5 is laid down to close the lower end opening of the sleeve body 1. In this state, the lid body 5 is closed. One end portion in the front-rear direction is received by the lower flange 3b and the left and right side edge portions are received by the receiving piece 12, respectively, to maintain a horizontal state.

Furthermore, when the duct B is attached to the sleeve body 1, the bolts and nuts 9 are removed, and the lower flange 3b of the sleeve body 1 is provided on the end surface of the duct B as shown by the phantom line in FIG. The flange b is abutted, and the mounting hole 4b provided in the lower flange 3b and the mounting hole provided in the flange b are bolted in the same manner as in the conventional case.
Fasten with a nut.

In the above embodiment, in order to hold the lid 5 in the upright state, the lid 5 is provided with the locking piece 11 for locking the mounting hole 4a provided in the upper flange 3a. ,
It is omitted when the sleeve body 1 is relatively small. Further, in the above description, when the sleeve body has a large size, the lid body 5 may be attached to the upper flange 3a so as to be capable of undulating, and in this case, the locking piece 11 and the receiving piece 12 are omitted.

[0013]

As described above, according to the present invention, since the lid body is integrally attached to the sleeve body, for example, after the opening work of the deck plate, the closing work by the lid body may be forgotten. Is extremely small, and
Since the pair of mounting holes on the hinge are arranged at the same pitch as the mounting holes on the flange of the sleeve body, the duct cannot be installed unless the hinge is removed from the sleeve body. There is no fear of performing construction by forgetting to remove the sleeve, and according to the configuration of claim 3, a part of the lid body protrudes from the upper end surface of the sleeve body, so that the opening state of the sleeve body is prevented from the outside. It can be easily confirmed, and particularly according to the configuration of claim 5,
There is an advantage that the opened state of the sleeve body can be recognized by the red color which is a dangerous color and it is effective for safety.
