Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a method for forming a wall such as a partition with mortar or concrete in a building or a building.
The present invention relates to a mounting structure for mounting the upper end side and the lower side of a three-dimensional wire mesh used as a base material of a wall to a building such as a floor or a beam of a building.

<< Conventional Technology >> In a building or a building, when a wall is made of concrete, mortar, or the like, as a three-dimensional wire mesh used as a base material, for example, those disclosed in JP-A-62-228554 It has been known. In this three-dimensional metal mesh, two lattice-shaped metal meshes formed by welding the intersections of metal wires arranged vertically and horizontally by welding are arranged in parallel at an interval.
Each end of the connecting metal wire is welded to the two lattice-shaped metal nets in a bridging manner, and the two lattice-shaped metal nets are connected to each other. Materials are arranged.

When a wall is formed by the three-dimensional wire mesh, a channel having a concave cross section is fixed downward on the upper lower surface of a building beam or the like, and an L angle is fixed on the lower upper surface of a floor or the like in an upright manner. Then, the upper end of the three-dimensional wire mesh is inserted into the channel, and the lower end is fixed to the L angle with bolts and nuts. Mortar is sprayed on both sides of the partition member of the three-dimensional wire mesh fixed in this way, and channels and L angles are embedded in the mortar together with the entire three-dimensional wire mesh to form a wall. Therefore, the upper and lower ends of the wall are fixed to beams and floors of a building.

<< Problems to be Solved by the Invention >> As described above, conventionally, a channel fixed to the upper part of a building such as a building and an L angle fixed to the lower part directly support the top and bottom of the three-dimensional wire mesh. Therefore, it is necessary to match the distance between the upper and lower channels and the L angle and the length of the three-dimensional wire mesh in advance, and if the distance and the length are incompatible, the support of the three-dimensional wire mesh is required. There are issues such as instability and difficulty in supporting. In addition, since the thickness of the three-dimensional wire mesh and the distance between the opposing walls of the channels need to be adjusted in advance, if there is a difference in the thickness of the three-dimensional wire mesh, the thickness of each three-dimensional wire mesh is adapted. There are also issues that require preparing multiple types of channels.

The lower end of the three-dimensional wire mesh is fixed to the L angle with bolts and nuts, but the height of the upright portion of the L angle is relatively low. Therefore, it is difficult to arbitrarily increase the position of the three-dimensional wire mesh when it is desired to fix the wire in accordance with the distance between the beam and the floor of the building and the size of the wire mesh. Moreover, even if a bolt is inserted through the three-dimensional wire mesh, the mesh of each wire mesh is quite large, and the three-dimensional wire mesh can be arbitrarily moved with respect to the bolt within the size of the mesh. For this reason, there are problems that it is difficult to stably fix the three-dimensional wire gauze, and a lot of trouble is required for stably fixing.

In addition, the wall body in which the three-dimensional wire mesh is embedded in a mortar or the like is fixed to the frame of the building at both upper and lower sides. Therefore, when vibration of the building frame due to an earthquake or the like causes a state in which interlayer displacement occurs between the building frame and the wall,
Since the wall is fixed to the building frame, it is difficult to smoothly absorb the interlayer displacement. For this reason, there is a problem that a part of the wall is likely to be damaged due to the vibration of the building frame due to an earthquake or the like.

The present invention is to solve the above problems,
Each of the upper and lower ends of the three-dimensional wire mesh can be stably supported irrespective of the dimensions such as the length and thickness of the three-dimensional wire mesh. An object of the present invention is to provide a mounting structure of a three-dimensional wire netting for a wall which can smoothly absorb interlayer displacement between a wall and a wall.

<< Means for Solving the Problems >> A first invention of a mounting structure of a three-dimensional metal mesh for a wall according to the present invention is a three-dimensional metal mesh formed by connecting two metal meshes arranged in parallel at a distance from each other with a connecting line. A wire mesh, a mounting member in which a connecting wire mesh is fixed to a bar-shaped connecting member by protruding on both sides in the width direction, and a supporting member fixed to an upper portion of a building such as a building; One of the members is formed in a groove shape having a concave cross section, and the other is formed in a convex shape in cross section which is slidably inserted into the member having the groove shape, and the connecting member is provided at a position overlapping with an upper end surface of the three-dimensional wire mesh. It is arranged, and the connecting wire mesh is folded and fixed on each of the wire meshes forming the three-dimensional wire mesh, and the mounting member is attached to the three-dimensional wire mesh, and the supporting member is attached to the upper part of a building such as a building, and connected. The material and the support member are slidably fitted to each other, The lower end of the wire mesh is attached to the lower part of the frame of the building or the like, so that the entire support member is exposed, and the three-dimensional wire mesh is embedded in a mortar or the like.

In the second invention, two parallel arrangements are provided at an interval.
A three-dimensional wire mesh formed by connecting a plurality of wire meshes with a connecting wire, and a belt-like mounting wire mesh in which a belt-like mounting plate is overlapped and fixed at an intermediate portion in the length direction, and the mounting wire mesh is constructed via the mounting plate. Each of the mounting meshes fixed to the lower part of the skeleton of the object and protruding from both sides of the mounting plate is bent upright and fixed on both sides of the three-dimensional wire mesh, and the upper end side of the three-dimensional wire mesh is the skeleton of the building or the like. It is characterized by being attached to the upper part.

<Operation> In the mounting structure of the three-dimensional metal mesh for a wall of the first invention, the connecting member is disposed at a position overlapping the upper end surface of the three-dimensional metal mesh, and the mounting member is fixed to the three-dimensional metal mesh. The connecting member protrudes from the upper end of the three-dimensional wire mesh. For this reason, a support member fixed to the upper part of a building such as a building and a connecting member are fitted together, and the entire support member is exposed, and the entire three-dimensional wire mesh is embedded in a mortar or the like to form a wall. It is possible to As described above, the wall can be formed by exposing the entire support member, so that the connecting member can slide with respect to the support member. That is, the wall body can slide in the width direction with respect to a building body such as a building. Therefore, when vibration occurs in a frame such as a building due to an earthquake or the like, and interlayer displacement occurs between the frame and the wall, the connecting member and the support member slide with each other to absorb the interlayer displacement. It is possible to prevent the wall from being damaged.

Then, the connecting material is formed by stacking connecting metal nets protruding on both sides thereof on both sides of the three-dimensional metal net, connecting the three-dimensional metal net and the connecting metal net to each other, and attaching the three-dimensional metal net to the three-dimensional metal net. Therefore, it is possible to stably attach the connecting member to the three-dimensional wire net having an arbitrary thickness, and arbitrarily set the interval between the upper end of the three-dimensional wire net and the connecting member within the range of the length of the connecting wire net. It is possible. For this reason, the connecting member can always be securely fitted to the supporting member fixed to the building or the like, and the upper end side of the three-dimensional wire mesh can always be securely attached to the building or the like, and any It is possible to stably attach the upper end side of the three-dimensional wire gauze having a thickness to a building such as a building via a connecting member.

The mounting structure of the three-dimensional metal mesh for a wall according to the second aspect of the present invention is characterized in that both sides of the mounting metal mesh fixed to a frame such as a building floor are bent upright according to the thickness of the three-dimensional metal mesh. Lay on both sides. Each of the mounting wire meshes is connected to a three-dimensional wire mesh, and the lower end side of the three-dimensional wire mesh is attached to a building such as a building. Therefore, it is possible to stably attach the lower end side of the three-dimensional wire mesh having an arbitrary thickness to a frame of a building or the like, and to provide the three-dimensional wire mesh within the length of the bent upright portion of the mounting wire mesh. Can be set arbitrarily. Since the bent mounting wire mesh and each of the wire meshes forming the three-dimensional wire mesh are connected to each other, the lower end side of the three-dimensional wire mesh can be stably attached to the mounting wire mesh immovably.

<< Example >> An example of a mounting structure of a three-dimensional wire mesh for walls of the present invention will be described with reference to the drawings. In the figure, reference numerals 1a and 1b denote two metal meshes which are arranged in parallel at a distance from each other, and are formed in a grid shape by welding intersections of metal wires arranged vertically and horizontally. Reference numeral 2 denotes a partition plate made of a styrofoam plate or a glass wool plate or the like disposed at an interval between the two wire nets 1a and 1b. Each end of the connecting wire 3 penetrating the partition plate 2 is connected to the wire nets 1a and 1b. By welding, the metal nets 1a, 1b and the partition plate 2 are connected to form a three-dimensional metal net 4 (see FIG. 3).

5 is a connecting member formed by bending a steel plate into a convex cross section,
Weld each end of the strip-shaped connection wire netting 6, 6 formed in a lattice shape to the portion bent outward at each end of each opposing wall, and attach it to both sides of the connection material 5 in the width direction. An attachment member 7 having connecting wire nets 6, 6 protruding therefrom is configured (see FIG. 2). The one connecting wire mesh 6 is bent in advance on the opposite side of the connecting member 5. Reference numeral 8 denotes a plurality of support holes provided through the connecting member 5 in the width direction.

Reference numeral 9 denotes a support member formed in a groove shape with a concave cross section. The support member 9 is formed so that the connecting member 5 can be slidably inserted.
Is provided with a connecting hole (not shown) overlapping the plurality of supporting holes 9 provided in the first hole.

Reference numeral 10 denotes a band-shaped mounting mesh formed of a grid-shaped metal net formed by welding each intersection of metal wires arranged vertically and horizontally, and a band-shaped mounting plate 11 is fixed to an intermediate portion in the length direction by welding. The mounting plate 11 is formed to be narrower than the gap between the wire meshes 1a and 1b, the width direction thereof is made to coincide with the length direction of the mounting wire mesh 10, and the mounting plate 11 is mounted on one side in the width direction of the mounting plate 11. The wire net 10 is bent upright in advance.

To attach the three-dimensional wire netting 4 to a building such as a building, the support member 9 is fixed to an upper part 13 of the building such as a ceiling or a beam with an explosive driving nail 14 with its opening downward. The mounting wire mesh 10 is fixed to the lower part 15 of the frame such as the floor with the explosive driving nail 16 through the mounting plate 11 in opposition to the fixed supporting member 9. At this time, the width direction of the support member 9 and the mounting plate
The width directions of 11 are matched (see FIG. 5). In addition, the supporting metal plate 17 having a concave cross section is used to
The support metal plate 17 is filled with mortar or the like and hardened. The bearing metal plate
The spacing between the opposing walls of 17 is set substantially equal to the thickness of the partition plate 2 (see FIG. 6).

Then, the connecting member 5 is inserted into the support member 9 and the support member 9 is inserted.
The plastic member 20 is inserted through the connecting hole provided in the first member and the supporting hole 8 of the connecting member 5 to temporarily connect the mounting member 7 to the supporting member 9. Next, the three-dimensional wire mesh 4 is placed at the position of the mounting plate 11, and the side surface of the three-dimensional wire mesh 4 is overlapped with the bent connection wire mesh 6 and the bent connection wire mesh 10. . The other side of the three-dimensional wire mesh 4 is bent and overlapped with the other side of the attachment wire 10 and the connection wire mesh 6, and the wire meshes 1a, 1b are connected to the connection wire meshes 6, 6 and both sides of the attachment wire mesh 10, respectively. Then, the three-dimensional wire mesh 4 is attached to the upper frame portion 13 and the lower frame portion 15 by the mounting member 7 and the mounting wire net 10.

At this time, the vertical position of the three-dimensional wire mesh 4 can be adjusted within the length of the mounting wire mesh 10, so that it can be fitted between the upper frame 13 and the lower frame 15 of almost any length. The three-dimensional wire net 4 can be attached. On the other hand, both side surfaces of the partition plate 2 of the three-dimensional wire mesh 4 are almost brought into contact with the bearing metal plate 17.

As described above, the upper and lower ends of the three-dimensional wire netting 4 are attached to a building such as a building. Then, mortar is sprayed on each surface of the partition plate 2 through the wire meshes 1a and 1b, and the entire wire meshes 1a and 1b are embedded in the mortar so that the mortar layers 21 and 1b are laid.
The wall 22 is formed by providing 21. When each of the mortar layers 21 is provided, the entire support member 9 is exposed,
A gap is formed between the upper end of 22 and the upper part 13 of the skeleton, and a part on the base side of the bearing metal plate 17 is exposed, so that a gap is also formed between the side part 18 of the skeleton and the mortar layers 21, 21.

Each gap formed on the upper end side and the side of the wall 22 has rock wool
23, etc., and the mouth of each gap is closed with an elastic non-combustible sealing material 24, so that the upper end and side of the wall 22 are almost independent of the upper frame 13 and the frame side 18. ing.

As described above, the upper end side of the three-dimensional wire netting 4 bends the connection wire nettings 6, 6 of the mounting member 7, and the lower end side of the three-dimensional wire netting 10 bends and supports the mounting wire net 10 in a sandwiched shape. Therefore, by setting each of the connecting wire mesh 6 and the mounting wire mesh 10 to an appropriate length, the three-dimensional wire mesh 4 supported within the range of those lengths.
Can be adjusted almost arbitrarily. Further, since the three-dimensional wire mesh 4 having an arbitrary thickness can be sandwiched between the bent state of the connecting wire mesh 6 and the mounting wire mesh 10, the three-dimensional wire mesh 4 having an almost arbitrary length and thickness can be stably supported. It is possible.

The connecting member 5 of the mounting member 7 is placed on the upper end surface of the three-dimensional wire mesh 4 so as to protrude upward from the three-dimensional wire mesh 4.
Install with 6,6. For this reason, it is possible to form the wall 22 by inserting the connecting member 5 into the support member 9 fixed to the upper portion 13 of the frame, exposing the entire support member 9, and burying the entire three-dimensional wire netting 4. it can. That is, while maintaining the state in which the connecting member 5 is slidable with respect to the support member 9,
Can be formed.

Therefore, when a skeleton of a building or the like vibrates due to an earthquake or the like and interlayer displacement occurs between the skeleton and the wall 22, the support member 9 and the connecting member 5 cause the plastic passing therethrough. Cut the pins 20 and slide each other smoothly. Since the interlayer displacement is easily absorbed by the mutual sliding of the support member 9 and the connecting member 5, it is possible to prevent the wall 22 from being damaged by the interlayer displacement.

When the wall 22 vibrates, the rock wool 23, the sealing material 24 and the partitioning material 2 are compressed against the frame
22 vibrates.

As in the above embodiment, the connecting member 5 is inserted in advance into the supporting member 9 fixed to the upper portion 13 of the frame, and the connecting member 5 is temporarily connected to the supporting member 9 with the plastic pin 20. If the connecting wire meshes 6, 6 of the mounting member 7 temporarily connected to the support member 9 are overlapped and connected to both side surfaces of the three-dimensional wire mesh 4, the distance between the upper frame 13 and the lower frame 15 and the length of the three-dimensional wire mesh 4 can be reduced. In an adapted state,
At each of the upper and lower ends of the three-dimensional wire mesh 4, each connecting wire mesh 6 and a mounting wire mesh
The attachment of the connecting member 5 to the supporting member 9 is easy and the mounting of the connecting member 10 is easy.

However, the mounting member 7 is first mounted on the upper end side of the three-dimensional wire netting 4. The three-dimensional wire net 4 is moved to the place where the three-dimensional wire netting 4 is arranged, and the connecting member 5 at the upper end thereof is inserted into the supporting member 9 fixed to the upper part 13 of the skeleton. It is also possible to attach the lower end of the three-dimensional wire mesh 4 to the mounting wire mesh 10 while maintaining the state in which the connecting member 5 is inserted into the support member 9. In this case, a plastic pin is used.
The use of 20 is unnecessary.

Further, a supporting metal plate 17 having a concave cross section corresponding to the thickness of the partition plate 2 is fixedly provided on the side wall portion 18 and filled with mortar or the like. The base side of the support metal plate 17 is exposed to form mortar layers 21 and 21, and the mortar layers 21 and 21 are formed.
A gap is provided between and the body side portion 18. Then the bearing metal plate 17
Part of the mortar layer 21, 21 overlaps on both sides of the tip of the mortar, and a part of the gap created between the wall 22 and the frame side 18 can be closed with the support metal plate 17, improving the closeability. Can contribute. However, it is also possible to form a gap between the skeleton side portion 18 and the wall 22 without providing the bearing metal plate 17.

If the partition plate 2 such as a styrofoam plate is arranged on the three-dimensional wire netting 4, it is possible to form the wall 22 by spraying mortar on each surface of the partition plate 2, and to form the wall plate 22. Thus, the heat insulation of the wall 22 can be improved. However, the arrangement of the partition plate 2 is optional. Therefore, the means for forming the wall 22 formed of mortar or the like by embedding the three-dimensional wire netting 4 also involves forming a mold at a distance from the three-dimensional wire netting 4 and forming the wall along the shape frame. Optional.

<< Effects of the Invention >> As described above, the mounting structure of the three-dimensional wire mesh for the wall of the present invention is such that a connecting member is attached protrudingly to the upper end of a three-dimensional wire mesh formed by connecting two wire meshes at intervals. The support member fixed to the upper part of the building such as a building and the connecting member are slidably fitted to each other, and the upper end side of the three-dimensional wire mesh is attached to the upper part of the building. Therefore, when the wall is formed by embedding the three-dimensional wire netting in mortar or the like, it is possible to expose the whole of the support member and maintain a state in which the support member and the connecting member can slide with each other. is there. For this reason, a building such as a building vibrates due to an earthquake or the like, and the interlayer displacement generated between the building and the wall is smoothly absorbed by the mutual sliding between the support member and the connecting member, and the wall is damaged. Such a situation can be prevented.

The attachment of the connecting material to the upper portion of the three-dimensional wire mesh is performed by bending the connecting wire mesh fixedly protruded on both sides in the width direction of the connecting material and overlapping the wire mesh on both sides of the three-dimensional wire mesh. Therefore, it is possible to stably attach the insertion projecting portion to a three-dimensional wire net having an arbitrary thickness. Since the distance between the upper end of the three-dimensional wire mesh and the connecting member can be almost arbitrarily adjusted within the range of the length of the three-dimensional wire mesh, the difference between the interval between the upper and lower parts of the frame and the length of the three-dimensional wire mesh can be adjusted. By absorbing the above, it is possible to attach the upper end of the three-dimensional wire mesh of almost any length to the upper part of the frame via the connecting member and the supporting member.

Further, the mounting structure of the three-dimensional wire mesh for the wall of the present invention, the lower end side of the three-dimensional wire mesh to the lower part of the building such as a building, the mounting wire mesh fixedly protruded on both sides in the width direction of the belt-shaped mounting plate, It is fixed to the lower part of the frame with the mounting plate. Then, the lower end of the three-dimensional wire mesh is arranged above the mounting plate, and both sides of the three-dimensional wire mesh are bent and overlapped on both side surfaces of the three-dimensional wire mesh to be connected to each wire mesh. Therefore, it is possible to easily and stably attach the mounting wire mesh to the lower part of the skeleton,
Since the three-dimensional wire mesh is sandwiched between the bent attachment wire meshes, it is possible to stably attach the three-dimensional wire mesh of almost any thickness so as not to move. It is also possible to attach the three-dimensional wire netting to an almost arbitrary height within the range of the length of the wire netting.
