Description

  The present invention relates to a structure for fixing a partition wall on a double floor on which a partition wall is installed on a double floor such as a floating floor and a dry sound insulation double floor for improving floor impact sound without impairing the sound insulation effect.

  Floating floors and dry double floors are used as a method for demonstrating the sound insulation performance of the floor between the upper and lower floors in the building, particularly as a method for reducing heavy floor impact sound. These floor structures absorb shocks by their buffering properties (softness), and are particularly effective against heavy floor impact sounds. Since the softness of these floor structures accompanies floor displacement, if the displacement (buffering property) is constrained by other members, the above effect cannot be exhibited, and sound insulation performance may be deteriorated. Therefore, it is necessary to pay great attention to the installation of partition walls combined with these floor structures.

  In general, there are floor wins and wall wins for wall and floor storage. FIG. 9 shows a cross-sectional view of an example of construction in which the partition wall 21 is set up on the dry double floor 20 with a wall win and FIG. 10 shows a cross section of an example of construction in which the partition wall 21 is set up on the dry double floor 20 with a floor win. The figure is shown.

In the case of a normal partition wall, it is divided into floor winning and wall winning depending on the purpose, but from the viewpoint of the construction method, the floor winning is simply superior in both workability and economical efficiency. That is, in the case of wall winning, the labor for processing the ceiling and floor members increases, so that the workability and economical efficiency are also inferior.
However, when partition walls are set up on floating floors or dry double floors, fixing the partition walls to these floors impairs the cushioning properties of the floor, so it is unavoidable that the partitions will win or the partition walls are suspended from the ceiling. Is required.

As shown in FIG. 9, when the partition wall 21 is set up on the dry double floor 20 with the wall winning, the workability is poor as described above, and when the wall position is moved by renovation or the like, the floor can be replaced. It becomes necessary and becomes a large-scale construction.
In order to suspend the partition wall from the ceiling, the strength of the ceiling is necessary, and the weight hanging on the ceiling varies, so excessive strength is required or the strength in the out-of-plane direction at the lower end of the partition wall cannot be secured. There are problems such as. In reality, it is impossible to suspend the partition wall with screws as the main component in the ceiling-mounted method.

  An object of the present invention is to provide a fixing structure for a partition wall on the double floor which is excellent in workability and can fix the partition wall to the double floor without falling the sound insulation performance of the double floor. That is.

The fixing structure of the double floor partition wall according to the first aspect of the present invention is a structure in which the partition wall is fixed on the upper floor of the double floor having the lower floor and the upper floor, and the wall width is below the partition wall. A plurality of bundle-like support legs that are arranged in a direction, each passing through the upper floor and having a lower end fixed to the lower floor, and a runner that is placed over the plurality of bundle-like support legs and that fixes the partition wall on the upper surface. A lateral load transmission / upward biasing member attached to the upper floor within the runner and capable of transmitting a lateral load acting on the runner to the upper floor and having elasticity for biasing the runner upward is provided. In addition, the "double floor" said by this invention is the meaning containing a floating floor.
According to this structure, the vertical load of a partition wall is supported by the lower floor of a double floor via a bundle-like support leg. An out-of-plane load such as a horizontal direction acting on the partition wall, for example, a force pushed by a person, is transmitted to the upper floor via the runner and the lateral load transmission / upward biasing member, and is supported by the upper floor. The lateral load transmission / upward biasing member is an elastic member that biases the runner upward, so that the vertical displacement of the upper floor during impact is not impaired by the lateral load transmission / upward biasing member. That's it. Moreover, since the runner is provided and the plurality of lateral load transmission / upward biasing members are connected, the resistance in the out-of-plane direction of the partition wall increases.
In this manner, the partition wall is fixed in the out-of-plane direction without restraining the displacement of the upper floor while supporting the partition wall vertically. Thereby, a partition wall can be fixed to a double floor by floor winning without deteriorating the sound insulation performance of a double floor. Furthermore, by providing a partition wall on the double floor in such a way that the floor wins, the workability and the economy can be improved.

  The lateral load transmission / upward biasing member may be a leaf spring extending in the wall width direction. When the leaf spring extends in the wall width direction, it is easy to bend in the vertical direction, but it is difficult to cause deformation in the out-of-plane direction of the partition wall. Therefore, the function of transmitting a lateral load with a single member and the function of urging the runner upward can be obtained, and a fixed structure with a simple configuration can be obtained.

The fixing structure of the double floor upper partition wall according to the second aspect of the present invention is a structure in which the partition wall is fixed on the upper floor of the double floor having the lower floor and the upper floor, and is provided on the lower end surface of the partition wall. A plurality of bundle-like support legs which are provided and extend in the wall width direction, and are arranged in the wall width direction in the lower groove, and each of which passes through the upper floor and is fixed to the lower floor with the lower end fixed to the lower floor. A lateral load transmitting / upward biasing member attached to the upper floor within the lower end groove and capable of transmitting a lateral load acting on the partition wall to the upper floor and having elasticity for biasing the partition wall upward; It is equipped with. The lower end groove of the partition wall is, for example, formed between the face material on both sides of the partition wall and the lower side frame material, or provided in the lower side frame material itself. May be.
In the case of this configuration, the runner is omitted as compared with the first invention, but the bundle-like support leg and the lateral load transmission / upward biasing member are fitted in the lower end groove of the partition wall. As with the invention, the bundled support legs and the lateral load transmission / upward biasing member function, and it is possible to fix the partition wall to the double floor with a floor win without deteriorating the sound insulation performance of the double floor. it can. Moreover, it will be excellent in workability.

A plurality of bundle-like support legs that are arranged in a direction, each passing through the upper floor and having a lower end fixed to the lower floor, and a runner that is placed over the plurality of bundle-like support legs and that fixes the partition wall on the upper surface. A lateral load transmission / upward biasing member attached to the upper floor within the runner and capable of transmitting the lateral load acting on the runner to the upper floor and having elasticity to bias the runner upward; For this reason, the partition wall can be fixed to the double floor without falling the sound insulation performance of the double floor, and the workability and economy are excellent.
When the lateral load transmission / upward biasing member is a leaf spring extending in the wall width direction, the degree of out-of-plane fixing of the partition wall is not restricted by the displacement of the upper floor due to the directionality of the elastic deformation. The function as a lateral load transmission / upward biasing member can be obtained with a single member, and a fixed structure with a simple configuration can be obtained.

  The fixing structure of the double floor upper partition wall according to the second aspect of the present invention is a structure in which the partition wall is fixed on the upper floor of the double floor having the lower floor and the upper floor, and is provided on the lower end surface of the partition wall.

An embodiment of the present invention will be described with reference to FIGS. The fixing structure of the double floor partition wall of this embodiment is to fix the partition wall 14 on the upper floor 12 of the double floor 10 having the lower floor 11 and the upper floor 12, as shown in FIG. A plurality of bundle-like support legs 1, a runner 2, and a lateral load transmission / upward biasing member 3 are provided.
The double floor 10 has a structure in which an upper floor 12 is supported on a lower floor 11 via a plurality of support legs 13 made of rubber or the like. The plurality of support legs 13 are interspersed. The lower floor 11 may be an on-site concrete slab or a floor slab such as a concrete plate or a lightweight concrete plate.

A plurality of the bundle-like support legs 1 are arranged below the partition wall 14 in the wall width direction, and penetrate the upper floor 12 and have their lower ends fixed to the lower floor 11. For example, as shown in FIG. 2, the bundle-like support leg 1 includes a head member 4 such as a plate piece and a screw-like member 5 fixed perpendicularly to the head member 4. For example, a screw-like member 5 that can be screwed into concrete is used as the screw-like member 5.
The runner 2 is a member that is arranged so as to cover the plurality of bundle-like support legs 1 and fixes the partition wall 14 on the upper surface. The runner 2 is made of channel steel as shown in FIG. 5D, for example, and is arranged in a posture in which the flange 2a faces downward.

  The lateral load transmission / upward biasing member 3 is an elastic member that is fixed on the upper floor 12 in the runner 2 and can transmit the lateral load acting on the runner 2 to the upper floor 12 and biases the runner 2 upward. It is a member which has. For example, as shown in FIG. 3, the lateral load transmitting / upward biasing member 3 is a strip-shaped leaf spring having a pair of wall contact surface portions 3b and 3b on both sides of the fixed surface portion 3a. The wall contact surface portion 3b is curved or bent so as to float upward with respect to the fixed surface portion 3a, and the wall contact surface portions 3b and 3b serve as spring portions. The fixed load portion 3a of the lateral load transmitting / upward biasing member 3 has a screw insertion hole 6, and the fixed surface portion 3a is fastened to the upper floor 12 with the screw 7 (FIG. 5C) via the screw insertion hole 6. By doing so, the lateral load transmission / upward biasing member 3 is fixed on the upper floor 12. The lateral load transmission / upward biasing member 3 made of this leaf spring is fixed to the upper floor 12 so as to extend in the wall width direction.

  As shown in FIG. 4, the width dimension of the runner 2 (the dimension between the flanges 2a and 2a) W is slightly larger than the width dimension of the lateral load transmission / upper biasing member 3, and the runner 2 is The load transmission / upward biasing member 3 can be covered. The partition wall 14 placed on the upper surface of the runner 2 is fixed to the upper surface of the runner 2 by fastening the horizontal frame member 8 (FIG. 4) at the lower end to the runner 2 with screws 9. The height dimension of the runner 2 (the height dimension of the flange 2a) H is set such that the screw 9 does not reach the upper floor 12.

Next, a procedure for fixing the partition wall 14 on the double floor 10 by this fixing structure will be described with reference to FIG. First, the double floor 10 is constructed in advance, and the line L of the partition wall 14 is drawn on the upper floor 12 of the double floor 10 as shown in FIG. Holes 16 for inserting the bundle-shaped support legs 1 are opened on the line L at a predetermined interval (for example, 455 mm pitch) using a drill 15 or the like.
The screws 5 of the bundle-like support legs 1 are inserted into these holes 16 as shown in FIG. 5B to fix the bundle-like support legs 1 to the lower floor 11. Further, the lateral load transmitting / upward biasing member 3 is fixed with a screw 7 at another position on the same line L, or substantially the same position as the bundle-like support leg 1 as shown in FIG. Next, the runner 2 is placed on the bundle-like support legs 1 and the lateral load transmission / upward biasing member 3 as shown in FIG.

  Accordingly, the runner 2 is arranged on the line L of the upper floor 12 while being supported by the lateral load transmission / upward biasing member 3 so as to be lifted. The lower end of the partition wall 14 is placed on the upper surface of the runner 2, and the horizontal frame member 8 at the lower end of the partition wall 14 is fastened to the runner 2 with screws 9 as shown in FIG. Fix it. A baseboard 17 is attached to the lower end of the outer surface of the partition wall 14 as shown in FIG.

With the partition wall fixing structure having the above-described configuration, the vertical load of the partition wall 14 is supported by the lower floor 11 of the double floor 10 via the bundle-like support legs 1. An out-of-plane load such as a horizontal direction acting on the partition wall 14, for example, a force pushed by a person, is transmitted to the upper floor 12 via the runner 2 and the lateral load transmission / upward biasing member 3. Supported by.
Since the lateral load transmission / upward biasing member 3 is a leaf spring, the lateral load transmission / upward biasing member 3 has high rigidity in the width direction a (FIG. 3) and is easily bent in the vertical direction. Therefore, by attaching the lateral load transmission / upper biasing member 3 made of this leaf spring so as to extend in the wall width direction, the strength in the out-of-plane direction at the lower end of the partition wall 14 is ensured, and the upper floor 12 at the time of impact The vertical displacement does not need to be damaged by the lateral load transmission / upward biasing member 3 made of this leaf spring.
Moreover, since the runner 2 is provided and the plurality of lateral load transmission / upper biasing members 3 are connected, the resistance in the out-of-plane direction of the partition wall 14 increases.

  Thus, the displacement of the upper floor 12 is not restrained while supporting the partition wall 14 vertically, and the out-of-plane direction fixing degree of the partition wall 14 can be ensured. Thereby, a partition wall can be fixed to a double floor by floor winning without deteriorating the sound insulation performance of a double floor. Furthermore, by providing a partition wall on the double floor in such a way that the floor wins, the workability and the economy can be improved.

  The lateral load transmission / upward biasing member 3 made of the leaf spring may be fixed integrally to the runner 2 as shown in FIG. In that case, a screw insertion hole 18 or the like is provided in the runner 2 so that the lateral load transmission / upward biasing member 3 can be screwed to the upper floor 12 from above.

Further, the lateral load transmission / upward biasing member 3 may be any member that can transmit the lateral load acting on the runner 2 to the upper floor 12 and has elasticity to bias the runner 2 upward, and is not illustrated. However, for example, a member that transmits a lateral load and an elastic member that is attached to the member and biases the runner upward may be used. Specifically, it may be composed of an upward groove-shaped lateral load transmission member and a rubber member that is fitted in the upper protruding state and biases the runner upward.
However, when the lateral load transmission / upward biasing member 3 is a leaf spring, due to its elastic deformability direction, there is a function of transmitting the lateral load with a single member and a function of biasing the runner upward. Thus, a fixed structure with a simple configuration can be obtained.

  In each of the above embodiments, the bundled support legs 1 and the lateral load transmission / upward biasing member 3 are provided separately and arranged apart from each other in the wall width direction. The upper urging member 3 may be, for example, a supporting leg and a lateral load transmission / upper urging member 19 that are integral with each other, as shown in FIG.

  The support leg / transverse load transmission / upper biasing member 19 of FIG. 7 is a bundle-like support leg 1 comprising a head member 4 such as a plate piece and a screw-like member 5 fixed perpendicularly to the head member 4. A lateral load transmission / upward biasing member 3 made of a strip-shaped leaf spring is attached. The lateral load transmission / upward biasing member 3 made of a leaf spring is provided on the lower surface of the head member 4, and both ends extend obliquely downward, and screw insertion holes 6 are provided at both ends. This support leg and lateral load transmission / upper biasing member 19 fixes the lower end of the bundle-like support leg 1 to the lower floor 11 as in the above embodiments, and both ends of the lateral load transmission / upward biasing member 3 are The screw is inserted into the screw insertion hole 6 and fixed to the upper floor 12 with a screw (not shown).

  The support leg / transverse load transmission / upper biasing member 19 is arranged in the wall width direction within the runner 2 in the same manner as the bundled support leg 1 and the lateral load transmission / upper biasing member 3 provided individually in each of the above embodiments. Set up side by side.

  FIG. 8 shows still another embodiment of the present invention. This embodiment is the same as the first embodiment shown in FIG. 1 except that the runner 2 is omitted, and the support legs 1 and the lateral load transmission shown in FIG. -The upper biasing member 19 is used.

  In this embodiment, the head member 4 of the bundle-like support leg 1 is directly fitted in the lower end groove 14a provided in the lower end surface of the partition wall 14 and extending in the width direction, and the vertical load of the partition wall 14 is applied on the upper surface thereof. receive. Further, the lateral load transmitting / upward biasing member 3 is also fitted directly into the lower end groove 14a of the partition wall 14, transmits the lateral load acting on the partition wall 14 to the upper floor 12, and moves the partition wall 14 upward. Energize.

  In the case of this configuration, the runner 2 in the embodiment of FIG. 1 does not have a function of connecting the plurality of lateral load transmission / upper biasing members 3, but the other lateral load transmission / upward biasing members 3 and the bundled support legs 1. The function is obtained in the same manner as in the first embodiment. For this reason, the partition wall 14 can be fixed to the double floor with a floor win without deteriorating the sound insulation performance of the double floor, and the workability is excellent.

  Also in the embodiment of FIG. 8, the bundled support legs 1 and the lateral load transmission / upward biasing member 3 shown in the first embodiment may be used.
