Description

  The present invention relates to a screenlessly connected cubicle, for example, used for a curtain wall or the like.

  2. Description of the Related Art Conventionally, a curtain wall structure is often used for a wall surface of a middle- to high-rise building or the like. In the curtain wall structure, uprights extending in the vertical direction are arranged at predetermined intervals in the horizontal direction, and blinds are arranged at predetermined intervals in the horizontal direction, and are connected to each other. Various panels such as a glass panel and a wall surface are mounted on a rectangular frame which is partitioned by a pair of adjacent cubicles and a blind.

  As an example of a building having such a curtain wall structure, one described in Patent Document 1 has been proposed. In this curtain wall, a plurality of sets of frame units composed of upper and lower horizontal members and left and right vertical members are arranged in the vertical and horizontal directions, and a panel such as a glass material is sandwiched between the frame units. A right member and a left member, which are vertical members of adjacent frame units, are fixed to each other with screws via a hollow portion, thereby forming a cubic.

In a split cubic type curtain wall composed of such vertical members divided into right members and left members, the following structures (1) to (3) are adopted as a structure for transmitting the unit's own weight and wind pressure strength to the frame. ) Is known.
(1) A structure in which an L-shaped bracket is fixed to each cubic outer surface, and a part of the bracket is fastened to a fixing bracket fixed to the body by bolts.
(2) A structure in which the split right and left members are integrated by fastening screws or the like, and only one side of the split is tied to the fixing bracket via a bolt.
(3) A structure in which the right member and the left member are not fastened to each other with screws or the like, and joint joints that also have the function of supporting the weight of the unit are used together, and the outer surfaces of one cubic body and the other cubic body And the bracket attached to the bracket is fastened together with a single bolt to the fixture.

JP-A-2005-2574

  However, in the above-described curtain wall, in the case of the structure (1) in which the bracket is fixed to the outer surface of the cubic, the bracket itself is exposed to the outside of the cubic, so that the appearance is deteriorated and the design of the external appearance is deteriorated. There was a problem. Further, in this case, since a bracket is required for each splitting method, there is a drawback that the cost of parts increases and the construction time is increased.

Further, in the case of the structure in which the split right member and the left member are integrated by fastening screws or the like as in the above (2), the split right member and the left member are restrained. Therefore, the right member and the left member have a structure that does not relatively shift, and there has been a problem that it is not possible to realize the follow-up property of interlayer displacement and the absorption structure such as the thermal expansion of the cross member (eyeless).
Further, in the case of the above-described structure (3), the number of brackets provided in a cubic manner can be halved compared to, for example, the structure of the above (1), but a part of the bracket is still exposed to the outside. Therefore, there was a problem that the design of the appearance was spoiled. In addition, each cubic structure is twisted in the direction of the weak axis (in-plane) and easily open to each other, and the force of the out-of-plane load (wind load) cannot be effectively transmitted to the skeleton. May be reduced, and there is room for improvement in that respect.

  The present invention has been made in view of the above-described problems, and achieves a good balance between improving appearance and appearance, securing wind pressure strength, improving workability, and reducing manufacturing costs. The purpose is to provide a state that can do it.

In order to achieve the above object, a cubic member according to the present invention includes a fixed cubic member fixed to a skeleton, and a movable cubic member that is connected eyelessly and movably held in the longitudinal direction of the eyeless eye. And a tip provided along an outdoor side surface on one of the fixed or movable movable member, and the fixed or movable movable member is provided with a tip plate along the outdoor side surface. On the other side of the directional member, a direction in which the fixed directional member and the movable directional member are separated from each other in the longitudinal direction from the outdoor-side distal end while being arranged in parallel along the indoor surface on the indoor side of the end plate. A projecting rib protruding outward is provided, and the projecting rib is disposed so as to overlap with the inside of the end plate in a hidden state without being exposed to the outdoor side .

In the present invention, the projecting ribs project outward from the outdoor end of the other cubic member toward the outside in the longitudinal direction, thereby providing a reinforcing structure that suppresses deformation of the cubic member. Can be improved. Furthermore, in this case, the inward force (force acting inward in the longitudinal direction) acting on the other stub member provided with the overhanging rib abuts on the other squire member, so that the twist is reduced. There is an advantage that can be suppressed. As described above, even when each of the cubic members (the fixed cubic member and the movable cubic member) receives the wind load, the movable cubic member moves in the eyeless longitudinal direction with respect to the fixed cubic member. The torsion and tilting of the cubic in the weak axis (in-plane) direction can be suppressed, and the out-of-plane (wind pressure) load acting on the cubic can be efficiently transmitted to the skeleton. The standing wind pressure can be increased.
As a result, for example, the fixed cubic member and the movable cubic member can be fixed to the skeleton by one-point support at the indoor end, and the conventional external bracket provided outside the cubic is unnecessary. In addition, the cost of parts can be reduced, and the workability can be improved. By eliminating the need for the external bracket, the external bracket can be hidden so as not to be exposed to the outside of the cubicle, so that the external appearance can be improved.

  Further, in the stance according to the present invention, the overhanging rib is disposed so as to overlap with the inside of the end plate and is hidden without being exposed to the outer surface of the curtain wall or the like, so that the appearance is improved. It becomes possible.

  Further, in the cubicle according to the present invention, it is preferable that a packing that abuts on the overhang rib is disposed on an inner surface of the end plate, and the overhang rib covers at least a part of the packing.

  In this case, even when the movable cubic member moves in the eyeless longitudinal direction with respect to the fixed cubic member, the state in which the overhanging rib abuts the packing provided on the inner surface of the end plate should be maintained. Can be.

  Further, in the method according to the present invention, on the inner surface of the end plate, an opening prevention guide for restricting relative movement in the depth direction with respect to the fixed stiffening member, and the packing are formed by extending the overhanging rib. It is preferable that the overhanging ribs are arranged in that order in the direction, and have an overhanging dimension that covers the opening prevention guide and at least a part of the packing.

  In this case, an opening prevention guide is provided between the overhanging rib and the end plate, so that relative movement in the depth direction with respect to the fixed cubic member can be restricted. Furthermore, by making the overhanging rib an overhanging dimension that can maintain a state of being in contact with the packing in the range of movement in the longitudinal direction, deformation of the above-described cubic member can be suppressed, and member costs are reduced. It is possible to set a suitable overhang size which is suppressed.

  According to the method of the present invention, it is possible to achieve a good balance between improving the appearance of the external appearance, securing the wind pressure strength, improving the workability, and reducing the manufacturing cost.

The projecting rib 13B of the fixed stanchion member 11 abuts on 17. As a result, the fixed cubic member 11 and the movable cubic member 12 form a cubic 2 that faces the airtight and liquid tight spaces with a gap k.

At the same time, the fixed cubic member 11 provided on the right side of the drawing with the blind 3 to the movable cubic member 12 of the frame unit 1A shown in FIG. 6, the indoor end plate 14A faces the upright portion 6b, and the shaft 7b of the second fastening bolt 7B is fastened with the nut 7D through the center hole 14b of the indoor end plate 14A and the hole of the upright portion 6b.
By repeating such operations sequentially, the frame units 1A and the like are sequentially connected to assemble the curtain wall 1 as an outer wall.
Thereafter, the glass panel 9 is mounted on the frame body separated by the pair of cubicles 2 and the blind 3 via the swallowing portion 18. The load of the glass panel 9 is also held by the fixed cubic member 11 via the movable joint sleeve 22 together with the movable cubic member 12 and the load of the blind 3.

Next, the operation of the cubic 2 of the curtain wall 1 according to the present embodiment will be described.
In the second embodiment, as shown in FIG. 3, the indoor end plate 14A and the second connecting flange 23B are fastened together as shown in FIG. It can be fixed to the frame with the fastening bolt 7B. That is, since the movable cubic member 12 is fixed to the fixed cubic member 11 by the second fastening bolt 7B so as to be movable in the blind axis direction P, the interlayer displacement of the curtain wall 1 including the cubic 2 is reduced. The followability is obtained, and the blind 3 connected to the movable cubic member 12 does not deform even if it expands or contracts under the influence of heat such as air temperature, and can be absorbed by the movement of the movable cubic member 12. .
More specifically, when the curtain wall 1 is exposed to a high temperature and the blinds 3 thermally expand in the cubic 2 according to the present embodiment, one of the blinds 3 is connected to the frame 5 via the fixing bracket 6. Although fixed to the fixed stationary cubic member 11, the other is connected to the movable cubic member 12 and thus expands due to thermal expansion. Then, the movable cubic member 12 of each cubic 2 moves by a small amount toward the fixed cubic member 11, and the second connecting flange 23B of the movable joint sleeve 22 moves in a direction overlapping with the indoor end plate 14A. be able to.

  Then, the indoor side end plate 14A, to which the framing 2 and the frame 5 are connected, is reinforced by the second connection flange 23B that is fastened together, resulting in a structure with increased rigidity. Therefore, since the wind load received by each of the cubic members 2 (the fixed cubic member 11 and the movable cubic member 12) can be transmitted to the skeleton through the highly rigid joint portion, the wind resistance of the cubic members 2 can be increased. it can.

Further, in the present embodiment, as shown in FIGS. 4 and 5 (a) and (b), the projecting rib 13B projects from the outdoor end toward the outside in the eyeless axial direction P, thereby forming the cubic member. Therefore, the rigidity of the entire cubic member can be improved. Further, in this case, an inward force (a force acting inward in the eyeless axial direction P) acting on the fixed cubic member 11 having the overhanging rib 13B comes into contact with the movable cubic member 12. There is an advantage that the twist is suppressed.
As described above, even when each of the cubic members 2 (the fixed cubic member 11 and the movable cubic member 12) receives the wind load, the eyeless axis of the movable cubic member 12 with respect to the fixed cubic member 11. While allowing movement in the direction P, it is possible to suppress twisting and falling in the weak axis (in-plane) direction of the cubic 2 and efficiently out-of-plane (wind pressure) load acting on the cubic 2 to the skeleton 5 side Since the power can be transmitted, the wind resistance of the cubic 2 can be increased.

Accordingly, the indoor end plate 14A of the fixed cubic member 11 and the second connection flange 23B of the movable joint sleeve 22 of the movable cubic member 12 are jointly fastened with the second fastening bolt 7B as in the present embodiment. Since it can be fixed to the skeleton 5 by one-point support, and a conventional iron external bracket provided on the outside of the square 2 becomes unnecessary, the cost of parts can be reduced and the workability can be improved. be able to. By eliminating the need for the external bracket, the external bracket can be hidden so as not to be exposed to the outside of the cubicle 2, so that the external appearance can be improved.
In particular, in the present embodiment, since the movable joint sleeve 22 is provided in place of the external bracket, the movable joint sleeve 22 can be formed from the same material as the cubic main body, such as aluminum. The material and manufacturing cost can be reduced, and the workability can be further improved.

  Further, in the second embodiment, the overhang rib 13B is disposed so as to overlap with the inside of the end plate 15A and is hidden without being exposed to the outer surface of the curtain wall 1, so that the appearance 2 The appearance can be improved.

Further, in the present embodiment, the second locking portion 15b is provided between the overhang rib 13B and the end plate 15A, so that the relative movement in the depth direction D with respect to the fixed upright member 11 can be restricted. .
Furthermore, by making the overhanging rib 13B have an overhanging dimension capable of maintaining the state of being in contact with the packing 17 in the range of movement in the eyeless axial direction P, the deformation of the above-described cubic member can be suppressed, and It is possible to set a suitable overhanging dimension with reduced cost.

  Furthermore, in the present embodiment, the joint sleeves 21 and 22 including the connecting flanges 23A and 23B are provided inside the cubicle 2 and can be hidden so as not to be exposed to the outside of the cubicle 2, so that the appearance can be improved. And the conventional external bracket can be omitted.

  Further, in the present embodiment, since the fixed-side joint sleeve 21 and the movable-side joint sleeve 22 are separate members from the fixed cubic member 11 and the movable cubic member 12, respectively, these joint sleeves 21 and 22 are cubic. Compared to the case where the members are integrally formed with the members 11 and 12, a mold having a complicated shape is not required. In addition, since the joint sleeves 21 and 22 may be attached to the cubic members 11 and 12 at the time of construction, the transportability of the cubic members 11 and 12 can be improved.

Further, in the present embodiment, the joint sleeves 21 and 22 can be attached to both the fixed cubic member 11 and the movable cubic member 12, so that the rigidity balance between both can be stabilized. For this reason, the wind resistance performance of the cubic 2 can be enhanced, and deformation such as twisting of the cubic 2 can be suppressed.
In addition, since one type of joint sleeve can be shared by the fixed cubic member 11 and the movable cubic member 12, the joint sleeve can be manufactured with one type of mold.

  In the present embodiment, the own weight receiving piece 32 of the movable side joint sleeve 22 attached to the movable upright member 12 is placed above the own weight receiving piece 31 of the fixed side joint sleeve 21 attached to the fixed upright member 11. Therefore, the weight of the curtain wall 1 received by the movable cubic member 12 can be efficiently transmitted to the fixed cubic member 11 via the movable joint sleeve 22 and the fixed joint sleeve 21.

  Further, in the present embodiment, since the joint sleeves 21 and 22 are disposed so as to protrude above the fixed cubic member 11 and the movable cubic member 12, the protruding portions of the joint sleeves 21 and 22 are formed by molding. Then, since the sealing material can be provided outside the mold, it is possible to prevent the sealing material from flowing into the cubic interior.
