Description

  The present invention relates to an underground floor ceiling back structure or the like in which equipment piping or the like is installed.

2. Description of the Related Art Conventionally, a ceiling structure with anti-seismic measures is known (for example, see Patent Document 1).
When installing equipment and piping in the ceiling space of the ceiling structure, the height of the ceiling space (ceiling pocket) is often increased, and earthquake resistance measures for the ceiling structure are required.
In particular, piping may be installed in a number of stages in the vertical direction in the ceiling space on the basement floor. For example, in a basement floor with a floor height of 6.8 m and a ceiling height of 4.3 m, a maximum of seven stages of equipment piping are installed on the back of the ceiling, and electrical wiring is interlaced. In this case, since the height of the back of the ceiling is high, it is necessary to install a steadying material (a member (brace) attached obliquely) for seismic reinforcement of the ceiling structure.

Japanese Patent Laid-Open No. 2015-90001

The space behind the ceiling of the basement floor is high, so when performing multi-level equipment piping work or electrical wiring work on the back of the ceiling, piping work using an aerial work vehicle etc. from the floor of the basement floor Wiring work must be carried out, and there is a problem that not only the risk in terms of safety is high, but also work efficiency is poor. In addition, since the height of the back of the ceiling is high, when constructing a ceiling structure with the first floor slab as a suspension source, the ceiling construction is difficult because the multi-stage equipment piping is installed in the space behind the ceiling. there were.
The present invention provides an underground floor ceiling back structure and the like that can facilitate work such as piping installation and electrical wiring in a ceiling space, and facilitate ceiling construction.

Since the basement ceiling back structure according to the present invention is characterized in that a cross member serving as a support part for supporting the work floor in the ceiling back space and the ceiling of the ceiling structure is provided above the ceiling plate. It is possible to facilitate work such as piping installation and electrical wiring in the ceiling space, and ease of ceiling construction.
In addition, since the cross member is supported by a support member installed in the partition wall, the cross member is reliably supported, and a support part for supporting the suspension base of the ceiling structure and the work floor of the ceiling space is provided. It can be formed reliably.
In addition, since the distance between the ceiling plate and the cross member is set to a distance that does not require the seismic reinforcement of the ceiling structure, the ceiling support structure can be simplified by eliminating the need for the seismic reinforcement work of the ceiling structure. Construction can be facilitated.
Moreover, since the cross member which connects the cross member provided so that it adjoins at intervals in the direction along the wall surface of a partition wall and the cross member was provided, the supporting force of a work floor can be improved.
In addition, according to the underground floor construction method according to the present invention, the pipe installation work in the ceiling space and the partition wall work under the ceiling are simultaneously performed using the above-described underground floor ceiling structure, thereby shortening the work period. Can be planned.

The figure which shows a basement ceiling back structure. The figure which looked at the support structure of a cross member, and the work floor formed on a cross member from the upper direction.

Embodiment 1
As shown in FIG. 1, the basement ceiling structure according to the first embodiment has a vertical direction behind the ceiling of the basement room space 200 partitioned by a partition wall 5 provided between the underground walls that are not illustrated. In the underground floor ceiling back structure in which the pipes 7 are installed in a plurality of stages, and the cross member 4 is provided above the ceiling plate 1 as a support part for supporting the work floor 2 and the ceiling structure 3. In addition, work such as piping installation and electrical wiring can be facilitated, and the seismic reinforcement work for the ceiling structure 3 can be eliminated, thereby facilitating the ceiling construction.

  For example, in a basement floor with a floor height of 6.8 m and a ceiling height of 4.3 m, the cross member 4 is provided at a position 1 m above the ceiling board 1.

For example, as shown in FIG. 2, the cross member 4 is connected to a support member 6 added to support the cross member 4 in the partition wall 5 of the underground floor. As this support material 6, for example, a steel square pipe was used.
That is, as shown in FIG. 2, the partition wall 5 is configured by adhering a gypsum board 5 b to a plurality of studs 5 a; 5 a... Built up at a predetermined interval, but adjacent studs 5 a; The cross member 4 is supported by the support member 6 by adding the support member 6 therebetween.
In addition, the support material 6; 6 installed in the both ends of the cross member 4 and the both ends of the cross member 4 is connected by welding or a connection tool outside a figure.
As described above, since the cross member 4 is supported by the support member 6 installed in the partition wall 5, the cross member 4 is reliably supported, and the work of the suspension source of the ceiling structure 3 and the ceiling back space 300 is performed. A support portion for supporting the floor 2 can be reliably formed. In addition, since the support member 6 is hidden in the partition wall 5 and is not exposed to the basement room space 200, the support member 6 does not get in the way of the basement room space 200, and the freedom of layout of the basement room space 200 is improved. In addition, the appearance of the basement room space 200 is not impaired.

  As shown in FIG. 2, a plurality of cross members 4; 4... Are provided on the same horizontal plane so as to be arranged at a predetermined interval, and the plurality of cross members 4; While being used, a work floor 2 is formed on the plurality of cross members 4;

  That is, as shown in FIG. 1, a suspension bolt 31 is attached to a cross member 4 used as a suspension base, and a field edge receiving hanger 32 is attached under the suspension bolt 31. The ceiling structure 3 is constructed by attaching the field edge receiver 33 to the field edge receiving hanger 32, attaching the field edge 34 to the field edge receiver 33, and attaching the ceiling plate 1 to the field edge 34. In this case, since the space | interval of the ceiling board 1 and the horizontal member 4 used as a suspension source is short, the earthquake-resistant structure of the ceiling structure 3 can be made unnecessary. That is, it is not necessary to install a steady rest material.

  1 and 2, the work floor 2 is formed by arranging a plurality of plate members 2a; 2a ... for forming the work floor 2 on the plurality of cross members 4; Then, by installing a work platform 20 such as a standing horse on the work floor 2 and performing work such as piping installation work and electrical wiring work, work such as piping installation work and electrical wiring work can be easily performed. become.

First, before constructing the partition wall 5 at the construction position of the partition wall 5, the support member 6 is installed, and a plurality of cross members 4; 4... Are installed on a horizontal plane about 1 m above the ceiling surface 1F. . That is, the cross member 4 is provided to be orthogonal to the wall surface of the partition wall 5.
And, below the plurality of cross members 4; 4..., The ceiling structure 3 is constructed and the partition wall 5 is constructed, and above the plurality of cross members 4; 4... Work floor 2 is formed on top, and work such as piping installation work and electric wiring work is performed using work scaffold 20 such as a standing horse.

  That is, after the installation of the plurality of cross members 4; 4..., The pipe installation work and the like in the ceiling space 300 located above the plurality of cross members 4; Since work such as partition wall construction can be simultaneously performed in the basement room space 200 located below, the construction period can be shortened. That is, the ceiling back space 300 is formed using a basement ceiling back structure provided with a cross member 4 serving as a support part for supporting the suspension base of the ceiling structure 3 and the work floor of the ceiling back space 300 above the ceiling plate 1. It is possible to simultaneously perform piping installation work and partition wall construction under the ceiling. That is, if the basement ceiling back structure of Embodiment 1 is adopted, it is possible to carry out at least the pipe installation work in the ceiling space 300 and the base construction work of the partition wall 5 under the ceiling, which shortens the construction period. It will be able to plan.

In particular, conventionally, for example, as shown in FIG. 1, in an area where the pipe 7 overlaps the ceiling space 300 in seven stages, the order of the work is complicated, and the work using an aerial work vehicle tends to be delayed. The delay in the work also caused a delay in the construction of equipment on the ground.
On the other hand, according to the embodiment, since the work scaffold 20 can be freely moved on the work floor 2, complicated piping work and the like can be easily performed.

Conventionally, for example, in the case where the ceiling structure is constructed by suspending the suspension bolts from the floor slab 101 on the first floor in an area where the piping overlaps the ceiling back space 300 in seven stages, the floor slab 101 on the first floor to the ceiling board is constructed. Because the distance becomes longer, seismic reinforcement is required. However, it is extremely difficult to perform a work for constructing a ceiling structure that requires seismic reinforcement in an area where the pipes are overlapped in seven stages, such as an operator having to work in an unreasonable posture.
On the other hand, in the embodiment, it is not necessary to perform ceiling foundation construction in the piping installation area, and the ceiling structure 3 can be constructed on the floor 100 of the underground floor using a normal scaffold. Moreover, since the distance from the horizontal member 4 used as a suspension source to the ceiling board 1 can be shortened, seismic reinforcement is not required, and therefore, the work of constructing the ceiling structure 3 can be easily performed.

That is, according to the basement ceiling back structure according to the embodiment, a plurality of cross members 4; 4... Serving as a support portion for supporting the work floor 2 and the ceiling structure 3 are provided above the ceiling board 1. As a result, the work floor 2 can be formed on the cross member 4, so that work such as piping installation and electrical wiring can be performed easily and safely.
In addition, by providing the cross member 4 above the ceiling plate 1 and shortening the distance between the cross member 4 and the ceiling plate 1, the cross member 4 can be used as a suspension base of the ceiling structure 3, Since the earthquake-resistant structure of the ceiling structure 3 can be eliminated, the ceiling structure 3 can be easily constructed, the cost related to the ceiling construction can be suppressed, and the construction period can be shortened.
That is, by setting the distance between the ceiling plate 1 and the cross member 4 to a distance that does not require the seismic reinforcement of the ceiling structure 3, it is possible to eliminate the need for the seismic reinforcement work of the ceiling structure 3 and simplify the ceiling support structure. This makes it easier to install the ceiling.

  In the above description, the cross member 4 is provided by being connected to the support member 6. However, the cross member 4 may be hung from the floor slab 101 on the first floor. In this case, the distance between the cross member 4 and the ceiling board 1 is brought close to a distance that can eliminate the earthquake-resistant structure of the ceiling structure 3. That is, the distance between the cross member 4 and the ceiling board 1 may be set to a distance that can eliminate the earthquake-resistant structure of the ceiling structure 3.
