Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a structure for attaching a floor plate for concrete pouring to a part of a building standpipe unit that penetrates the concrete floor of each floor serving as a fire prevention zone. It is something.

[Prior Art] To explain an example of a construction standpipe unit, as shown in Fig. 3.4, angles are installed on the vertical frame 1 at the four corners at fixed height intervals, that is, at the height of the concrete floor of each floor. Top steel or channel steel.

The middle and lower three stages are assembled to form a horizontal frame 2, and a support beam 3 is provided on the vertical frame 1 above the horizontal frame 2 of each stage.
The lower portions of a plurality of, for example, three standpipes 4 are fixed to the two lower support bars 3 with fixing hardware 5, and the middle and upper portions of the three standpipes 4 are fixed to the middle and upper support bars 3, respectively. The U-shaped metal fittings 6 that penetrated through the support beams 3 were held by the U-shaped metal fittings 6, and nuts were tightened to both ends of the U-shaped metal fittings 6 that penetrated the support beams 3, and the floor plates 7 for concrete pouring were attached to each of the horizontal frames 2. There is.

In the architectural standpipe unit 8 having such a configuration, the part of the standpipe unit 8 that penetrates the concrete floor, which is a fire prevention zone, is framed by a horizontal frame 2 made of angle steel or channel steel, and concrete is poured into it. A pipe sleeve 10 that covers the outside of the standpipe 4 is attached to the periphery of the through hole 9 to which the floorboard 7 for concrete placement is attached and the standpipe 4 that requires heat insulation of the floorboard 7 for concrete pouring is inserted. ,
After concrete is placed on the floor plate 7 for concrete placement, a heat insulating and non-combustible fireproof material such as rock wool or ceramic wool is stuffed between the pipe sleeve 10 and the standpipe 4.

[Problem to be Solved by the Invention] By the way, the mounting structure of the floor plate for concrete pouring of the above-mentioned architectural standpipe unit 8 is similar to that when angle steel or channel steel is assembled into the vertical frame 1 to form the horizontal frame 2. The construction standpipe unit 8 must be welded at multiple points, which requires a large number of man-hours, making it difficult to efficiently manufacture the construction standpipe unit 8. Furthermore, the construction standpipe unit 8 is heavy, increasing material costs and transportation costs.
was a factor in increasing costs.

SUMMARY OF THE INVENTION Therefore, the present invention provides a mounting structure in which a floor plate for concrete pouring is directly welded to a vertical frame without incorporating a horizontal frame made of angle steel or channel steel into the vertical frame.

[Means for solving 'B problem] The above li! In order to solve this problem, the structure for attaching a floor plate for concrete pouring of a standpipe unit for construction of the present invention has a structure in which the peripheral edge of a floor plate for concrete pouring, which has a through hole for inserting a standpipe at a predetermined position, is shaped like or It is characterized in that it is formed into a U-shape to form ribs, and the ribs are welded to the vertical frames at the four corners of the architectural standpipe unit.

[Operations] As mentioned above, the structure for attaching the floor plate for concrete pouring of the architectural standpipe unit of the present invention has an integral]-shaped or U-shaped rib formed on the peripheral edge of the floor plate for concrete pouring, so that
The concrete casting floor plate is equipped with a horizontal frame with the same strength as conventional angle steel or channel steel, so the ribs on the periphery of the concrete casting floor plate are welded directly to the vertical frames at the four corners of the architectural standpipe unit. As a result, there is no need to incorporate angle steel or channel steel into the vertical frame to form a horizontal frame as in the past, reducing man-hours and making architectural standpipe units more efficient. It can be manufactured well. In addition, the weight is reduced, material costs and transportation costs are reduced, and the cost of construction standpipe units can be reduced.

[Example] An example of the floor plate mounting structure for concrete pouring of the architectural standpipe unit of the present invention will be described with reference to Fig. 1.2.
The rib 15 is formed by bending the peripheral edge of a rectangular floor plate for concrete pouring in which three through holes 9 for inserting the stand pipes 4 are bored in parallel downward into a U-shape. Concrete pouring floor plates 7' formed with a The ribs 15 of the pouring floor plate having an angle of 7° were welded to the vertical frame 1 at the four corners.

A pipe sleeve 10 is attached to the floor plate 7° for concrete pouring of the architectural standpipe unit 8° configured in this manner at the outer circumferential side of the through hole 9 through which the standpipe 4 that requires heat insulation passes. After pouring concrete on the floor plate 7, rock wool is inserted between the pipe sleeve 10 and the standpipe 4 which is inserted into the through hole 9 and supported and fixed to the support bar 3 provided on the vertical frame 1 in the same manner as before. It is packed with heat insulating and non-combustible fireproof materials such as ceramic wool.

In the concrete pouring floor plate mounting structure of the above embodiment, a rib 15 having the same strength as a conventional angle steel horizontal frame is integrally formed on the peripheral edge of the concrete pouring floor plate 7. Since it has a structure in which it is directly welded to the vertical frame 1 at the four corners, there is no need to incorporate angle steel or channel steel into the vertical frame to form a horizontal frame as in the past. Therefore, the construction standpipe unit 8' could be manufactured efficiently with less man-hours. Furthermore, the weight is reduced, material costs and transportation costs are reduced, and the cost of the construction standpipe unit 8' can be reduced.

Incidentally, in the above embodiment, the rib 15 in the shape of ] is formed on the peripheral edge of the floor plate 7 for concrete pouring, but the rib 15 in the shape of a U may be formed instead. In addition, those ribs are provided below the 7° peripheral edge of the concrete pouring floor plate,
It may also be provided above.

[Effects of the Invention] As described above, the floor plate mounting structure for concrete pouring of a construction standpipe unit according to the present invention does not require the horizontal frame of angle steel or channel steel to be assembled into the vertical frame.
Since the floor plate for concrete pouring is directly welded to the vertical frame, the number of man-hours is small and the standpipe unit for construction can be manufactured efficiently. In addition, the weight is reduced, which reduces material and transportation costs, making it possible to reduce the cost of construction standpipe units.
