Description

  The present invention relates to an installation structure of a partition wall having a through hole for inserting an electric wire.

  In general, a partition wall is erected between rooms. As this type of partition wall, there is known a partition wall panel having a through hole for communicating the ceiling back and the interior space of the partition wall at the upper end portion. Thus, the electric wires arranged on the back of the ceiling are introduced into the internal space of the partition wall, and the electric wires can be connected to a wiring device disposed in the internal space of the partition wall without exposing the electric wire to the interior (for example, Patent Document 1). ).

  The partition wall consisting of the above partition wall panel is installed with its upper end attached to the ceiling edge where the ceiling panel is suspended or pasted, but when installing the partition wall on the ceiling edge like this, The partition wall installation structure shown in Fig. 1 is useful and has been used conventionally. In this installation structure, a plurality of first partition walls arranged in parallel so as to be opposed to each other with a predetermined gap in plan view, and end faces of the partition walls are abutted and arranged in a straight line. A plurality of second partition walls which are provided and are vertically adjacent to the first partition walls. Above each first partition wall, two ceiling field edges that are parallel to the first partition wall and orthogonal to the second partition wall in a plan view are arranged, and are positioned above the same first partition wall. The opposite side surfaces of the two ceiling field edges are located above both surfaces of the first partition wall. A plurality of other ceiling field edges different from the two ceiling field edges positioned above the first partition wall are arranged at predetermined intervals on both sides of the two ceiling field edges positioned above the first partition wall. More specifically, a ceiling field edge or first partition located above each of the opposing surfaces of the adjacent first partition walls among the two ceiling field edges located above each first partition wall. If the ceiling field edge located above each of the opposing faces of the adjacent first partition wall facing the building body wall and the building body wall arranged in parallel with the wall is defined as the reference ceiling field edge, Arrange each of the other ceiling field edges so that the center in the thickness direction in the plan view of the ceiling field edge overlaps the position obtained by equally dividing the distance between the centers in the thickness direction in the plan view of both reference ceiling fields. Yes.

  And by the installation structure of the partition wall, the block-shaped timber is placed on the upper surface of the first partition wall so as to be positioned between the two ceiling field edges located above the same first partition wall, and Attach wood to the two ceiling edges with a fastener so that the top of the first partition wall can be attached to the two ceiling edges, and the wood is placed on the top of the second partition wall And two ceiling field edges located above each first partition wall and other field edges by attaching the wood with a fixing tool, and two ceiling field edges located above each first partition wall; The upper end of the second partition wall can be attached and fixed to the other ceiling field edge.

  A particularly useful point in the installation structure of the partition wall is that the opposing side surfaces of the two ceiling field edges located above the first partition wall are positioned above both surfaces of the first partition wall, so that the ceiling field edge The ceiling board can be fitted and mounted well, and the through hole formed in the first partition wall can be prevented from being blocked by the ceiling edge, and the other ceiling edge is correspondingly In order to maintain the strength of the ceiling with reference to the two ceiling edges located above the first partition wall, they are equally arranged at a predetermined interval.

  However, in the installation structure of the partition wall, the through hole drilled in the second partition wall may be completely blocked by the ceiling field edge perpendicular to the second partition wall in plan view. Despite having a hole, it may not be possible to connect the electric wire behind the ceiling to the wiring device arranged in the internal space of the second partition wall. In such a case, a laborious work such as making the through hole at a location where the ceiling edge is not provided is necessary.

In addition, since the installation location of the first partition wall with respect to the second partition wall differs depending on the design plan, the through hole is provided in a portion excluding the location where the ceiling edge at the upper end of the partition wall is previously arranged in the factory. If it tries to pierce | pierce, the drilling location of this through-hole must be changed for every design plan, and the manufacturing cost of a partition wall will become high.

It consists of the face material 8 which consists of a gypsum board stuck on both surfaces. The panel frame 7 is constructed between a panel frame body 10 formed by a pair of left and right vertical bars 10a and 10b and a pair of upper and lower horizontal bars 10c and 10d in a rectangular frame shape, and the upper and lower horizontal bars 10c and 10d. And a middle vertical beam 11 for reinforcing the panel frame main body 10 formed. The middle vertical rail 11 connects middle portions of the upper and lower horizontal rails 10c and 10d in the longitudinal direction, and the space 18 surrounded by the rectangular frame-shaped panel frame body 10 is partitioned by the middle vertical rail 11. Thus, on both sides in the longitudinal direction of the horizontal rails 10c, 10d of the space 18, instrument placement spaces 12a, 12b constituting the internal space 12 of the partition wall 1 are formed.

  The horizontal beam 10c on the panel frame main body 10 which is the upper end portion of the partition wall 1 sandwiches the middle vertical beam 11 with two through holes 13a and 13b for inserting electric wires which are paired in advance at the factory. However, two sets, one set on each side, are provided, and the two through-holes 13a, 13b forming the set are arranged in the longitudinal direction of the partition wall 1 with a gap therebetween. Each of the through holes 13a and 13b is circular and penetrates the horizontal rail 10c in the vertical direction to connect the internal space 12 and the upper part of the partition wall 1 (that is, the back of the ceiling described later). Of the two sets of through-holes 13a and 13b, one set of through-holes 13a and 13b arranged at one end in the longitudinal direction of the partition wall 1 is one end in the longitudinal direction of the partition wall 1. The other end of the partition wall 1 in the longitudinal direction of the partition wall 1 is communicated with the appliance disposing space 12a located at the other end in the longitudinal direction. The space 12b for instrument arrangement | positioning located in the other end side of the longitudinal direction of the partition wall 1 and the ceiling back are connected.

  As shown in FIG. 1, the partition wall 1 is arranged so as to be vertically adjacent in a plan view. In the installation structure of this embodiment, one partition wall 1 among the partition walls 1 that are vertically adjacent in the plan view. A plurality of first partition walls 1a are arranged in parallel with a predetermined interval a in plan view, and the second partition wall 1b, which is the other partition wall 1, is abutted against one end surface in the longitudinal direction. Are arranged in a straight line. Each first partition wall 1a abuts the end face in the longitudinal direction to one surface in the thickness direction of the second partition wall 1b, and the center in the thickness direction of the first partition wall 1a is abutted against the second partition wall 1b in plan view. It is located at a position shifted from the end face 2 in the longitudinal direction of the second partition wall 1b. It is assumed that the upper surface of each first partition wall 1a is flush with the upper surface of each second partition wall 1b.

  Above each of the first partition walls 1a, two ceiling field edges 3a that are parallel to the first partition wall 1a in plan view and orthogonal to the second partition wall 1b in plan view are disposed. The distance b between the opposing side surfaces 4 of the two adjacent ceiling field edges 3 a located above the first partition wall 1 a is the same as the thickness dimension of the partition wall 1. That is, each of the opposing side surfaces 4 of the two ceiling field edges 3a positioned above the same first partition wall 1a is positioned above both surfaces 5 facing the thickness direction of the first partition wall 1a.

Further, both sides of the two ceiling field edges 3a located above the first partition wall 1a (that is, the direction opposite to the facing direction of the two ceiling field edges 3a located above the same first partition wall 1a) ) Includes a plurality of other ceiling field edges 3b different from the two ceiling field edges 3a located above the first partition wall 1a at a predetermined interval c in parallel with the two ceiling field edges 3a. They are arranged side by side. Here, the predetermined interval c is a distance between other adjacent ceiling field edges 3b or a distance between the ceiling field edge 3a and another ceiling field edge 3b adjacent to the ceiling field edge 3a. This predetermined interval c is an interval generally used to maintain the strength of the ceiling, and as shown in FIG. 1, between the opposing side surfaces 4 of the two ceiling field edges 3a located above the same first partition wall 1a. Greater than the distance b. Specifically, the ceiling field edge 3a located above each of the opposing surfaces of the adjacent first partition walls 1a, or a building frame wall (not shown) parallel to the first partition wall 1a and the second wall adjacent to the building frame wall. When defining ceiling ceiling joist 3a located above the respective opposing surfaces one partition wall 1a, a the reference ceiling ceiling joist 3a _1, wherein the predetermined interval c, the center position in the thickness direction of each of the other ceiling ceiling joist 3b Is a value that overlaps a position obtained by dividing the center-to-center distance j in the thickness direction of each of the two reference ceiling edges 3a ₁ into a plurality of equal parts (three equal parts in the illustrated example). In the illustrated example, this predetermined distance c is adjacent to each other. The center-to-center distance i in the thickness direction of adjacent ceiling field edges 3a and 3b excluding the two ceiling field edges 3a is set to a value that is about 303 mm. Note that the thickness dimension e of the two ceiling field edges 3a and the other ceiling field edges 3b located above the first partition walls 1a are all the same value, and this thickness dimension e is a conventional general ceiling field. It is assumed that the thickness dimension of the partition wall 1 is smaller than that of the edge 3.

  The upper surface of the upper horizontal rail 10c, which is the upper surface of the second partition wall 1b, is in contact with the lower surfaces of the two ceiling field edges 3a and the other ceiling field edges 3b located above each first partition wall 1a. In this state, the first partition wall 1a and the second partition wall 1b are attached to the ceiling edge 3a, 3b by a fixing tool (not shown) such as a bolt. Specifically, as shown in FIG. 1, block-like timber 6a is mounted on and attached to the upper surface of each first partition wall 1a, and two ceilings located on both sides of the timber 6a are located above the first partition wall 1a. Wood is applied to each of the two ceiling field edges 3a with a fixing tool driven from the side surface 16 opposite to the opposite side surface 4 of the two ceiling field edges 3a in a state where the opposite side surfaces 4 of the field edge 3a are in contact with each other. 6a is fixed, whereby each first partition wall 1a is fixed to the two ceiling field edges 3a located above the first partition wall 1a, and on the upper surface of each second partition wall 1a. Each of the second partition walls 1a is fixed to the ceiling edges 3a and 3b by mounting and attaching the block-like wood 6b and fixing the wood 6b to the ceiling edges 3a and 3b with a fixing tool. . In addition, the said timber 6a, 6b shall be arrange | positioned in the position which does not block | close all the through-holes 13a, 13b.

  In addition, a ceiling board (not shown) is attached to the ceiling field edges 3a and 3b arranged side by side as described above, or is attached to the lower surface of the ceiling field edges 3a and 3b. Above the ceiling plate, for example, a ceiling like a double ceiling ceiling is formed.

  A wall-embedded wiring device 14 such as a switch, an outlet, an interphone master unit, or the like is disposed in an internal space 12 of the partition wall 1 among the partition walls 1. An electric wire 15 such as a power line or an information line such as a VVF cable arranged is introduced into the internal space 12 of the partition wall 1 through the two through holes 13a and 13b, and the electric wire 15 Is connected to a wiring device 14 disposed in the internal space 12 of the partition wall 1. Specifically, as shown in FIG. 2, for example, wiring devices 14 are disposed in the device placement spaces 12a and 12b of the partition wall 1, and in the example of FIG. The electric wire 15 arranged on the back of the ceiling connected to the wiring device 14 is introduced into the device placement spaces 12a and 12b in which the wiring device 14 connected through the through holes 13a and 13b is disposed, and the wiring device 14.

  The center-to-center distance d of each pair of through-holes 13a and 13b drilled at the upper end of each partition wall 1 in the partition wall 1 installation structure is as shown in FIG. 1 or FIG. 3 or less, the distance b between the opposing side surfaces 4 of the two ceiling field edges 3a positioned above the same first partition wall 1a, more specifically, the same first partition wall 1a. The distance b is the same as the distance b between the opposing side surfaces 4 of the two upper ceiling edge 3a. The diameters of the through holes 13a and 13b are such values that a later-described electric wire 15 can be inserted through half of the hole surfaces of the through holes 13a and 13b. Specifically, the through holes 13a and 13b in the illustrated example are used. Is approximately the same value as the thickness dimension e of the ceiling edge 3.

  Thus, the center distance d in plan view of the two through holes 13a and 13b that form a pair is the distance between the opposing side surfaces 4 of the two ceiling field edges 3a positioned above the same first partition wall 1a. The second distance is equal to or smaller than the distance b, and the predetermined distance c is larger than the distance b between the opposing side surfaces 4 of the two ceiling field edges 3a located above the first partition wall 1a. Of the pair of through holes 13a and 13b drilled in the partition wall 1b, at least half of the hole surface of at least one of the through holes 8a (or 8b) is not blocked by the ceiling field edges 3a and 3b, so In other words, in the present embodiment, the total area of the hole surfaces that are not blocked by the ceiling edge 3a, 3b in the two pairs of through holes 13a, 13b is at least one. More than the area of the hole surface of the two through holes 13a That. Therefore, the electric wires 15 arranged on the back of the ceiling can be reliably introduced into the internal space 12 of the second partition wall 1b via the through holes 8a (or 8b) not blocked by the ceiling edge 3a, 3b. Thus, as shown in the conventional example, it is not necessary to drill through holes 13a and 13b at the site, and the construction of the partition wall 1 is facilitated, and the through holes 13a and 13b are drilled for each design plan. Therefore, the manufacturing cost of the partition wall 1 can be reduced. It is also possible to achieve the above-described effect by forming the one set of long holes in the longitudinal direction of the partition wall 1 at the upper end of the partition wall 1 by connecting the pair of through holes 13a and 13b. However, in the present embodiment, the structure of the partition wall 1 is not provided by such a long hole, and in particular, each of the pair of through-holes 13a and 13b is disposed at intervals in the longitudinal direction of the partition wall 1. The upper strength is increased. One of the face materials 8 attached to both surfaces of the partition wall 1 is attached after the installation of the wiring device 14 and the electric wire 15.

  Next, an embodiment different from the previous embodiment will be described below. In addition, the same number is provided about the same structure as previous embodiment, and description is abbreviate | omitted about the overlapping description.

  As shown in FIG. 4, in the present embodiment, the end face of the first partition wall 1a is abutted against the second partition wall 1b so that the center in the thickness direction of the first partition wall 1a matches the abutting end face 2 of the second partition wall 1b. All the through-holes 13a and 13b that are abutted against the end portions and are formed in the upper end portion of the second partition wall 1b are located above the same first partition wall 1 in the horizontal rail 10c of the second partition wall 1b. The two ceiling field edges 3a are formed at positions excluding the range h between the side surfaces 16 opposite to the opposing side surfaces 4.

The distance g in the longitudinal direction of the partition wall 1 from the center of the through hole 13a located at the end to the end face on the one end side in the longitudinal direction of the partition wall 1 is defined as two ceiling fields located above the first partition wall 1a. A value obtained by adding half (b / 2) of the distance b between the opposing side surfaces 4 of the edge 3a, the thickness dimension e of the ceiling field edges 3a and 3b, and the radius f of the through holes 13a and 13b. That is, g = b / 2 + e + f. Similarly, a through hole 13b located on the other end side in the longitudinal direction of the partition wall 1 out of another set of the through holes 13a and 13b provided at the end portion on the other end side in the longitudinal direction of the partition wall 1. The distance g in the longitudinal direction of the partition wall 1 from the center of the partition wall 1 to the end face on the other end side in the longitudinal direction of the partition wall 1 is also the opposite side surface 4 of the two ceiling field edges 3a located above the first partition wall 1a. A value obtained by adding half (b / 2) of the distance b between them, the thickness dimension e of the ceiling field edge 3 in plan view, and the radius f of the through hole 13a (or 13b) is added. Here, the value obtained by adding the diameter (2 × f) of the through holes 13a and 13b to the distance d between the centers of the two through holes 13a and 13b as a pair is smaller than the above-described predetermined distance c. It shall be.

  As described above, all the through holes 13a and 13b drilled in the upper end portion of the second partition wall 1b are located above the same first partition wall 1 in the horizontal rail 10c of the second partition wall 1b. By drilling at a location excluding the range h between the side surface 16 opposite to the opposite side surface 4 of the ceiling field edge 3a, a pair is formed at the upper end of the second partition wall 1b. The through-holes 13a, 13b do not communicate with the back of the ceiling from the two narrow ceiling field edges 3a located above the same first partition wall 1a, and all the holes formed in the second partition wall 1b All the hole surfaces of the through holes 13a and 13b are not blocked by the ceiling edges 3a and 3b, and all the hole surfaces of all the through holes 13a and 13b drilled in the upper end portion of the second partition wall 1b.
