Description

Description: TECHNICAL FIELD The present invention relates to a curtain wall used as a non-bearing wall and provided for a space section in front of a frame of a structure.

[Conventional technology]

In general, as a curtain wall, a product obtained by driving a stone material into a precast concrete slab is used. However, since the precast concrete slab is heavy and the production type must be changed when producing different types, it is not possible to respond flexibly. Further, a curtain wall in which a frame is attached to a building frame and a thin outer wall material is directly fixed to the frame is easily broken when an external force such as an earthquake or a typhoon acts, and there is a problem in securing water tightness.

[Problems to be solved by the invention]

The present invention has been made in view of the above-described circumstances, and has as its object to obtain a curtain wall that is lightweight, easy to manufacture, and can reliably withstand an external force such as an earthquake typhoon.

[Means for solving the problem]

The invention according to claim 1 is a steel support frame,

An arm protruding in the lateral direction, wherein the arm enters the frame of the support frame and serves as a load support portion.

According to the present invention, it is possible to reduce the weight of the support frame, the plate member, and the outer wall material, which constitute most of the weight of the curtain wall. Further, the support frame can be easily manufactured by cutting a steel frame material or the like into a predetermined size and then connecting the support frame into a bar shape. The outer wall plate can be adapted by cutting a stone material into a relatively thin wall or the like, and there is no difficulty in manufacturing. The support frame and the plate member may be made of a steel material.

In addition, the support frame transmits the external force such as wind force to the structure body and reliably supports it, and the arm as a support means against horizontal external force such as an earthquake causes the support frame to move the support frame in the vertical plane. Absorb by moving relative to the building.

This arm supports vertical load at two points on the left and right near the upper end of the support frame with respect to the structure body, and makes one of the support points rotatable with respect to the other, so that The support frame swings around the support point and absorbs.

In addition, the support frame can be mounted so as to be relatively movable in the horizontal direction with respect to the structural body, so that displacement in the horizontal direction can be absorbed.

Further, the arm enters the inside of the frame of the support frame, and supports the load of the support frame at the portion that enters the inside of the frame. Therefore, the load supporting portion of the support frame is located inside the support frame, and as a result, the thickness of the curtain wall in the inside and outside of the building can be reduced, and the living space can be enlarged.

The invention according to claim 2 is characterized in that a precast concrete bar is attached to an outer peripheral side of the support frame, and the holding means is provided on the bar.

According to the present invention, a precast concrete rod having a uniform cross-sectional shape, which is cut to a predetermined dimension, can be used. It is easy and cost reduction is possible.

In this case, the precast concrete bar has a different shape between the bar disposed outside the warp of the support frame and the bar disposed outside the weft of the support frame when the support frame has a rectangular frame shape. be able to.

According to a third aspect of the present invention, in the holding means, a mounting bolt is erected on a small arm mounted on a support frame, and a mounting hole of a hook mounted on an outer wall plate is vertically fitted to the mounting bolt. The outer wall plate is supported on the support frame by screwing the nut to the mounting bolt.

According to the present invention, the mounting bolt is erected from the small arm mounted on the support frame, and the mounting hole of the hook mounted on the outer wall plate is vertically fitted to the mounting bolt. The external wall plate can be easily attached to the support frame by screwing the nut from the support frame.

The invention according to claim 4 is characterized in that the first sealing means and the second sealing means form a closed space together with the holding means.

Accordingly, even when rainwater or the like intrudes through the first sealing means disposed outside the building, the rainwater is reliably captured in the closed space, and does not enter the inside of the building through the second sealing means. .

(Example of the invention)

1 to 6 show a first embodiment of the present invention. As shown in FIGS. 2 and 3, in the curtain wall of this embodiment, a plurality of outer wall plates 12 are supported on a support frame 10, and the support frame 10 is attached to an H-shaped steel 14 of a building frame.

As shown in FIG. 1, the support frame 10 is a pair of vertical materials.
16 are arranged in parallel with each other, and are spanned by horizontal weft materials 18 and 19 which are horizontally arranged between upper and lower ends of these vertical materials 16, and are formed in a frame shape as a whole. A plurality of (three in this embodiment) weft materials 22 are stretched between the middle portions of the length materials 16 to be parallel to the weft materials 18 and 19. Vertical 16, horizontal
Reference numerals 18 and 19 denote steel materials having a rectangular cross section at a right angle in the longitudinal direction.
Has a rectangular cross section in which a part of the lower surface is cut out. The vertical material 16 is formed to have a greater depth dimension in the inside and outside of the building (the direction of the arrow A in FIG. 1) than the horizontal materials 18 and 19. However, these vertical members 16 and horizontal members 18, 19, 22 are welded to each other so that the outer surfaces of the building are flush with each other. If necessary, as shown in FIG. 2, a turnbuckle tension bar 24 for connecting the corners of the length member 16 in a diagonal manner may be reinforced.

The weight acting on the support frame 10 is supported by an arm 26 fixed to the H-section steel 14. These arms 26 are groove-shaped steels whose bases are welded to the H-shaped steel 14 and whose longitudinal direction is in the direction of arrow A, and the groove-shaped open surfaces are arranged downward. As shown in FIG.
A nut 27 is welded to the tip of the support bolt 28.
Are screwed together with the axis vertical. Each arm 26 is provided near each end of the weft material 18 and has a function of supporting the weight acting on the support frame 10 with the H-shaped steel 14. By adjusting the amount of screwing of the support bolts 28 to the nuts 27, the mounting height of the left and right ends of the support frame 10 can be adjusted.

As shown in detail in FIG.
It corresponds to the lower surface of 18. This allows the support frame 10
You will be in the inside of the. As described above, since the support portion of the support frame 10 enters the inside of the support frame 10, the depth dimension (in the direction of the arrow A) for supporting the support frame 10 is extremely small.

Vertical plates 32 are welded to the upper ends of the vertical members 16, respectively. The hatched portion in FIG.
3 shows a welded portion to the surface.

These vertical plates 32 are formed with long holes 33 extending in the vertical direction, and mounting bolts 34 penetrate from the outside to the inside of the building. The mounting bolt 34 is inserted into a slot 37 of the angle member 36 fixed to the arm 26 and screwed to a nut 39 fixed to a vertical piece of the angle member 36 via a washer 38. Further, a circular hole 41 is formed in the angle member 36 adjacent to the elongated notch 37, and a nut 42 is welded. A push bolt 43 is screwed into the nut 42 from inside the building. The tip of the push bolt 43 is in contact with the vertical plate 32.

Therefore, by adjusting the amount of screwing of the mounting bolt 34 to the nut 39 and the amount of screwing of the push bolt 43 to the nut 42, the support frame 10 is moved in the depth direction of the building (the direction of arrow A) as shown in FIG. Positioning is performed, and the load acting on the support frame 10 in the depth direction of the building is transmitted to the H-shaped steel 14 via the mounting bolt 34, the push bolt 43, and the angle member 36.

In addition, as shown in FIG.
The combination of the mounting bolts 34 and the push bolts 43 applied to both ends of 10 is mounted on the same angle member 36.

Here, as shown in FIG. 5, the support frame 10 can swing about the mounting bolt 34 (in the direction of arrow B in FIG. 1). That is, when the support frame 10 receives an external force such as an earthquake and receives a load in the vertical direction, the support frame 10 can swing in the arrow B direction around the mounting bolt 34 of the weft material 18. In this case, when the support frame 10 swings around the support point of the left or right mounting bolt 34 of the weft material 19, the other mounting bolt 34 moves up and down in the elongated hole 37 of the angle material 36. become. In order to facilitate the swinging operation of the support frame 10, a washer 45 is inserted into the mounting bolt 34 on the surface in contact with the vertical plate 32, and the surface of the washer 45 in contact with the vertical plate 32 is made of fluororesin or the like. Low friction material is stuck. Preferably, this washer 45 is welded to the head of the mounting bolt 34.

A horizontal plate 47 is welded to the upper end of the vertical material 16. From this horizontal plate 47, a positioning bolt 48 is erected, and a suspension circular hole 49 is formed adjacent thereto.

A horizontal plate 51 is welded to the lower end of the vertical material 16. The horizontal plate 51 has a groove shape in which both ends in the depth direction of the building are bent downward, and a positioning hole 52 through which the positioning bolt 48 of the horizontal plate 47 passes is formed.

Accordingly, the support frame 10 is inserted into the positioning bolts 48 of the horizontal plate 47 fixed to the upper end of the support frame 10 disposed at the lower stage by inserting the positioning holes 52 of the horizontal plate 51 attached to the lower end thereof.
The lower end of 10 is positioned at the upper end of the support frame 10 disposed at the lower level, and is positioned in the depth direction of the building (the direction of arrow A) and in the width direction perpendicular thereto. However, the combination of the positioning holes 52 and the positioning bolts 48
When the rocker 10 rocks in the direction of the arrow B, the positioning bolt 48 is pulled out of the positioning hole 52 by a required amount to enable the rocking of the support frame 10.

A metal plate 56 is fixed to a surface of the support frame 10 outside the building. The metal plate 56 is surrounded by vertical wood 16 and horizontal wood 1
It is welded to 8, 19, and 22 to close the inner side of the support frame 10.

A horizontal piece of an angle material 61 is welded to the top surface of the horizontal material 18, and a mold 62 is attached to the vertical piece. This profile
Reference numeral 62 denotes, for example, a shape formed by extruding aluminum, which has a longitudinal direction in the horizontal direction, and a vertical perpendicular cross section having the same shape. The head of the mounting bolt 65 is inserted into a U-shaped portion 62A in which an opening facing the inside of the building is formed, and the leg of the mounting bolt 65 has a circular hole 61A formed in the angle material 61. The shape member 62 is fixed to the angle member 61 by being penetrated and screwed to a nut 66 fixed to the angle member 61.

A vertical piece 62B continuing from the U-shaped portion 62A covers the front surface of the weft material 18, and a sealing material 67 is interposed between the lower end and the metal plate 56.

Further, a U-shaped portion 62C opened upward is formed at the upper part of the U-shaped portion 62A, and the base of the rubber gasket 68 is accommodated therein. The tip of the rubber gasket 68 is formed in a thin loop shape, and can be flexibly deformed.

As shown in FIG. 4, a similar molding 62 is fixed upside down to the weft 19, and a rubber gasket 68 is similarly mounted upside down. Therefore, the pair of rubber gaskets 68 is in close contact with the vertically adjacent support frame 10, and has a water stopping function. The shape member 62 is formed with a small arm 62D extending from between the U-shaped portion 62A and the vertical piece 62B to the outside of the building,
A hook 69 constituting a holding means together with the mold 62 is fixed by a bolt 71. The hook 69 has a U-shaped tip, and the tip is housed in a holding groove 12A formed in the outer peripheral portion of the outer wall plate 12 to support the upper and lower ends of the outer wall plate 12.

A mold member 73 is also fixed to the outside of the vertical member 16 of the support frame 10 via an angle member 74. This mold 73 is also a mold
Similar to 62, has a U-shaped portion 73A, a horizontal piece 73B, a U-shaped portion 73C and a small arm 73D, and a rubber gasket is inserted into the U-shaped portion 73C.
75 are accommodated. This rubber gasket 75 elastically adheres to the adjacent rubber sket 75 and has a water stopping function. Further, a hook 76 is fixed to the small arm 73D with a bolt 77, and a front end portion is housed in the holding groove 12A. The both sides of the outer wall plate 12 are held to perform positioning in the left-right direction.

1, the upper end of the small arm 73C is extended as shown by an imaginary line, and the outer end of the small arm 73C is brought into contact with the outer ends of the lower end of the lower arm 73C. Materials are interposed to seal between the left and right ends of the mold 62 and the upper and lower ends of the mold 73. In addition, rubber gasket 68,
75 can be arranged as an endless shape around the outer wall plate 12 with both ends connected to each other.

As shown in FIGS. 1, 4, and 6, a vertical member 81B and 81C are formed at both upper and lower ends of a U-shaped portion 81A for accommodating a bolt 83 for mounting to the horizontal member 22. Thus, a gap between the end portion of the metal plate 56 and the metal plate 56 is sealed by the sealing material 84. A rectangular portion 81E is formed on the small arm 81D extending in the horizontal direction from the upper end of the U-shaped portion 81A, and the head of the bolt 85 is accommodated. The bolt 85 has a rectangular portion 81 formed so as to be slidable in the rectangular portion 81E in the longitudinal direction (the direction perpendicular to the plane of FIG. 6) of the mold 81. This rectangular part 81E
The nut 87 is screwed into the leg of the bolt 85 projecting upward from the hook 85 after penetrating the hook 86. The hook 86 has an insertion portion 86A formed at the tip of the outside of the building, and is inserted into the holding groove 12A. Therefore, the hook 86 supports the load at the lower end of the outer wall plate 12 and also positions the upper end.

In particular, when the hook 86 is attached to the mold member 81, the nut 87 may be screwed into the bolt 86 after it is simply placed and inserted into the upright bolt 86, so that assembly is extremely simple.

Note that a cushion rubber material is interposed between the hooks 69, 76, and 86 and the holding groove 12A. A seal material 91 and a seal back-up material 92 are filled between the ends of the adjacent outer wall plates 12. Further, a fireproof covering material or a heat insulating material is attached to the back surface of the metal plate 56 as necessary.

As shown in FIGS. 4 and 5, the space between the sealing material 91 and the rubber gaskets 68 and 75 is a drainage space 93 partitioned by the shape members 62 and 73, respectively, and the building extends along the end of the outer wall plate 12. They communicate vertically and horizontally. For this reason, sealing material
91 constitutes the first sealing means, and rubber gaskets 68, 75
Constitutes a second sealing means to double seal water intrusion from between the ends of the outer wall plate 12. Further, even when the sealing material 91 is broken and water enters, the water is drained through the drainage space 93, so that water does not enter the inside of the building.
In the drainage space 93, the space between the tips of the hooks 69 and 76 on the outside of the building is narrow, and the space between the small arms 62D and 73D is wide. It is very unlikely that the flowing water will be suddenly weakened and will pass through the rubber gaskets 68 and 75 and enter the interior of the building.

The assembly of the present embodiment configured as described above includes a support frame.
After fabricating 10, the metal plates 56 are welded to the outer side surfaces of the support frame 10 respectively. Further, the shape members 62, 73 and 81 are fixed to the length material 16 and the weft materials 18 and 19, respectively. Rubber gaskets 68 and 75 are attached to the mold members 62 and 73. Further, the outer wall plate 12 is supported on the support frame 10 via the hooks 69, 76, and 86, respectively.

The positioning holes 52 of the horizontal plate 51 arranged at the lower end of the support frame 10 are inserted into the positioning bolts 48, and the upper end of the vertical material 16 is mounted on the support bolts 28. Also, after penetrating the mounting bolt 34 into the vertical plate 32,
While positioning it to the nut 39.

Thus, the curtain wall of the present invention is a support frame.
Since 10 is formed of a thin steel plate and the outer wall plate 12 is also relatively thin, it weighs about 1/3 as compared with a conventional curtain wall made of precast concrete, and is easy to assemble.

The load acting from the outside of the building to the inside due to wind pressure and the like is applied from the outer wall plate 12 to the support frame 10 via the hooks 69, 76 and 86
Is transmitted to. Since the vertical plate 32 is supported by the angle member 36 as shown in FIG. 5, the support frame 10 is reliably transmitted to the H-shaped steel 14 via the arm 26, and the lateral load is supported.

When a lateral load such as an earthquake acts on this curtain wall, the support frame 10 is attached to one of the mounting bolts 34.
Swings in the direction of the arrow B through and is absorbed.

Also, as described above, the sealant 91 and the rubber gaskets 68 and 75 form a two-stage seal against rainwater intrusion from between the outer wall plates 12, and the drainage space 93 reliably prevents water from entering the inside of the building. .

When a lateral load is applied, such as during an earthquake, the support frame
This load may be absorbed by moving the 10 relatively to the structure body in the horizontal direction instead of the swinging motion. In this case, the long hole-shaped notch 37 formed in the angle member 36 may be formed in the longitudinal direction in the horizontal direction, and the positioning hole 52 formed in the horizontal plate 51 may have the same shape as the long hole.

Next, FIGS. 7 to 9 show a second embodiment of the present invention.

In this embodiment, mold members 101 and 102 made of precast concrete are used instead of the mold members 62 and 73 in the above embodiment.

As shown in FIG. 9, the profile 101 arranged outside the length 16 has a substantially rectangular horizontal cross section, and a cutout 101A is formed on the opposite surface of the length 16. Bolts 105 project in a horizontal direction from a core 104 embedded in the mold 101, and the bolts 105 are formed in through holes 106, 10
Inserted into 7. Further, the head of a positioning bolt 108 screwed to the vertical member 16 is in contact with the mold member 101.

Therefore, by adjusting the amount of screwing of the positioning bolt 108 to the vertical material 16, the distance between the positioning material 108 and the vertical material 16 is adjusted, and by screwing the nut 109 to the tip of the bolt 105, the vertical screw 16 is securely connected to the vertical material 16. Is fixed.

After the nut 109 is screwed and fixed, a reliable positioning is performed by welding the angle member 111 previously fixed to the corner of the mold member 101 to the angle member 112 fixed to the vertical member 16. In addition, the space between the mold member 101 and the vertical member 16 is filled with a seal member 113 to perform a water stopping operation.

On the mold 101, a rubber gasket 75 and a hook 115 are arranged on the opposite side of the length 16 with a notch 101A therebetween. The hook 115 is fixed by bolts 117 via a block 116 previously embedded in the shape member 101 and a rubber 118 is provided between the hook 115 and the side surface of the outer wall plate 12.
The horizontal positioning of the outer wall plate 12 is performed via the. In this embodiment, the holding groove 12A is not formed on the side surface of the outer wall plate 12.

As shown in FIG. 8, the mold 102 at the upper end of the support frame 10 has a notch 102A at the middle and a hook 121 at the tip like the mold 101, but the hook 121 is bent downward at the tip. It enters the holding groove 12A of the outer wall plate 12 to support the upper and lower ends of the outer wall plate 12 as in the above-described embodiment. The mold 102 is attached to the weft 18 of the support frame 10 in the same manner as the mold 101.

As shown in FIG. 8, the mold 102 is bent on the side close to the building frame so that the drainage space 93 formed between the mold 102 and the mold 102B attached to the lower end of the adjacent support frame 10 is bent. The shape members 102B protrude in the direction approaching each other on the far side of the building frame. Thus, the bent drainage space 93 reliably prevents water from entering the building frame. Similarly, the shape member 102B is attached to the horizontal member 19 of the support frame 10, and the hook 121 is attached to the outer wall plate 1B.
The second holding groove 12A is supported.

As shown in FIG. 7, a notch 102C continuous with the notch 102A is formed at both ends in the longitudinal direction (horizontal direction) of the mold 102, and communicates with the notch 101A of the mold 101.

The mold members 101 and 102 thus configured are formed by forming the mold members 101 and 102 having the same cross-sectional shape into a long dimension as compared with the mold members 62 and 73 of the above embodiment, and cutting and using the necessary length. Production is extremely simple.

Next, FIGS. 10 to 12 show a third embodiment of the present invention.

In this embodiment, a holder 132 for accurately positioning a plurality of outer wall plates 12 is shown. This holder 132
As shown in the figure, a male screw 134 is engraved on the base and a tip 132
A is bent at a right angle. The tip 135A of the bar 135 fixed to the intermediate portion is bent at a right angle and arranged in parallel with the bar 132A. The distance between these tips 132A and 135A is such that the outer wall plate 12 is sandwiched in the thickness direction as shown in FIGS.

On the outside of the building, a bar 138 is temporarily provided in a horizontal direction, and a bracket 141 having a U-shaped cross section is put on the bar 138, and fixing bolts 142 penetrating the bracket 141 are provided on the bar 138.
8, the bracket 141 is fixed to the bar 138.
When the fixing bolt 142 is loosened, the bracket 141
Can be slid in the longitudinal direction. The vertical piece of angle material 143 fixed to the bracket 141 has a male screw on the holder 132
134 penetrates. Nuts 144 and 145 are screwed into the male screw 134 on both sides of the angle member 143. These nuts 14
The mounting positions of 4, 145 are determined such that the outer wall plate 12 is accurately aligned in the depth direction of the building (the direction of arrow A) with the outer wall plate 12 sandwiched between the tip portions 132A, 135A. I have.

Therefore, in this embodiment, the distal end portions of the plurality of holders 132 are inserted from between the adjacent outer wall plates 12 and rotated around the axis in the direction of arrow C to hold both side surfaces of the outer wall plate 12. Thus, the outer wall plate 12 is positioned in the depth direction of the building. The outer wall plate 12 is supported and fixed to the building frame by the mounting structure of each embodiment. In this state, the holder 132 is reversed in the direction of arrow C and the bracket 141 is removed from the outer wall plate 12 by removing the bracket 141 from the bar 138 or the like. The gap between the outer wall plates 12 is filled with a sealing material and closed.

As a result, in this embodiment, it is possible to accurately and easily finely adjust the number of outer wall plates 12 in the depth direction of the building.

〔The invention's effect〕

Since the present invention is configured as described above, it is possible to obtain a curtain wall that is lightweight and has water tightness and load resistance.
