[0002]

2. Description of the Related Art In recent years, inexpensive PC curtain walls excellent in design, decoration, fire resistance and the like have been very often used as exteriors of middle and high-rise buildings. When designing the exterior using this PC curtain wall, various construction methods such as a panel type, a spandrel type, or a erected type are used.
There is a beam type construction method.

When designing an exterior by the construction method shown in FIG. 10, first, a pillar-shaped PC board 1 is sequentially attached to each pillar of a skeleton from the outside thereof through a fastener, and the plurality of PC boards 1 are mounted.
Joint 4 of predetermined dimension (for example, 25 mm) between
And a joint gasket 5A as a secondary seal material from the inside.
Is installed appropriately. Then, a beam-shaped PC board 2 is sequentially attached to each beam of the skeleton from the outside thereof through a fastener, and thereafter, a primary seal (not shown) is attached to the joint 4 having a predetermined dimension between the plurality of PC boards 1 and 2 from the outside thereof. If the joint material gasket 5A is appropriately applied from the inside to the backup material, the exterior can be designed.

The column-shaped PC board 1 and the beam-shaped PC board 2 are manufactured by curing and demolding at a factory using one kind of lightweight concrete, various aggregates, admixture materials, water and the like. And joint 4
Are formed on the joints 1a and 2a, respectively, and a joint gasket 5A is bonded to the mounting groove 3 with an adhesive.

[0005] The joint gasket 5A is shown in FIG.
2 As shown in (a) and (b), the height is 40 mm and the width is 30 m
It is made of a hollow elastic deforming body 6A having a substantially oval cross section and is appropriately formed into a rod shape, an L shape, a frame shape, or the like according to a construction mode or the like. Such joint gaskets 5A are deformed by abutment with the PC board 1, and maintain airtightness and watertightness.

Japanese Patent Application Laid-Open No. 8-128122 is a prior art document relating to this type of building gasket, building, and construction method.

[0007]

As described above, a conventional middle-to-high-rise building has a beam-shaped structure between a plurality of pillar-shaped PC boards 1.
When the PC board 2 is pulled in later, the exterior is often installed. In addition, the joint gasket 5A in the related art has a height dimension longer than the width dimension and the predetermined dimension of the joint 4 in consideration of a change in a predetermined dimension of the joint 4 due to a temperature change, an earthquake, or the like. Therefore, in this type of conventional field, there are the following problems.

First, when the beam-shaped PC board 2 is retracted and comes into contact with the pillar-shaped PC board 1, as shown in FIG. 10B, the joint gasket 5A is misaligned in its width direction. It is large and easily bends and deforms easily when lying down.
In combination with the repulsive force of the plate 2 (for example, 100 kg or more per PC plate), the construction becomes extremely complicated and complicated. Secondly, if the joint gasket 5A is misaligned and deformed into an abnormal shape, it becomes impossible to sufficiently secure the safety, airtightness, and / or watertightness of the building.

As a means for solving the first and second problems, a method of increasing the width of the elastically deformable body 6A to prevent deformation in the width direction can be considered. However, the method of increasing the width of the elastically deformable body 6A cannot be adopted due to restrictions in the thickness direction of the PC board 2, the presence of the primary seal and the backup material, the space occupied by the depressurizing groove, and the like. Therefore, in solving the above problem, it is assumed that the width dimension of the joint gasket 5A is not largely changed.

Alternatively, it can be formed in a cross-sectional shape similar to these. This elastically deformable body may or may not have a ratio of height dimension / width dimension of 1 or more. Further, the elastically deformable body can be appropriately formed into a substantially sealed structure such as a substantially bar-shaped, L-shaped, or frame-shaped.

The term architectural gasket must be understood in a broad sense, at least a gas-tight gasket used for sealing sashes and doors, a joint gasket used for joints of building components, a foam gas-tight material. , A foam glazing gasket, or a foam joint gasket. Further, the term "inside" the height direction of the elastically deformable body is a term for distinguishing it from the term "width direction", and does not necessarily mean the vertical direction. Therefore, it means a vertical direction, a horizontal direction, a depth direction, a left-right direction, or the like as appropriate according to the mounting mode. The number of the hollow chambers may be two or more. Further, the number of partition walls, communication holes, and / or circulation holes may be two or more. In addition, the substantially turtle-shaped cross section includes an abacus ball shape, an oval shape, a hexagonal shape, or a similar shape.

A tube (for example, having a diameter of 5 to 8 mm and a length of 1

According to the first aspect of the present invention, the partition partitioning the hollow chamber is oriented in the width direction of the elastically deformable body, and the ratio of the height dimension to the width dimension of the hollow chamber is set to 1 or less. Even if an external load acts on the body, deformation of the elastically deformable body in the width direction is suppressed or prevented. Therefore, the elastically deformable body is deformed in the height direction to change the height dimension value and to maintain the sealing property. Further, since the communication hole is provided through the partition wall, gas flows from one hollow chamber to another hollow chamber or from another hollow chamber to one hollow chamber when deformed in the height direction.

According to the second aspect of the present invention, the thick portion is formed thicker than the peripheral wall in the vicinity to improve rigidity, and at least the hollow chamber closest to the thick portion has a flat portion.

Spills out of the body. On the other hand, when the elastically deformable body has a substantially hermetic structure in which the end face is closed, the gas in the elastically deformable body flows out of the hollow through the flow hole and out of the elastically deformable body. According to the fourth aspect of the present invention, the gas in the elastically deformable body flows out of the elastically deformable body through the hollow chamber and the tube sequentially. Since the object of the exhaust work is not an elastically deformable body but a tube, the work is easy. According to the fifth aspect of the present invention, the gas in the elastically deformable body sequentially flows through the entire hollow chamber and the tube and flows out to the pressure reducing means. According to the sixth aspect of the present invention, by operating the flow control means, the gas in the tube can be passed or stopped, or the flow rate of the gas can be freely controlled.

According to the seventh aspect of the present invention, when gas flows out of all the hollow chambers in the elastically deformable body, passes through the flow holes or tubes, and flows to the outside of the elastically deformable body or to the pressure reducing means, the elastically deformable body. Is deformed in the height direction. In this state, when the building component provided with the joint gasket and another building component are opposed to each other via the joint, the dimension of the elastic deformable body is shorter than the joint size. Can be suppressed or prevented, and a building component or an elastically deformable body can be appropriately combined with another building component. When the building component and another building component are opposed to each other, if the gas flows from outside of the elastic deforming body or from the decompression means into the entire hollow chamber through a circulation hole or a tube, the elastic deforming body has a height. The direction can be restored to contact the other building components in the correct position, and the joints can be sealed to build at least a portion of the building.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited to the following embodiments. The building in the present embodiment is a single type of PC boards 1 and 2 for constructing the exterior of a middle and high-rise building, and a single type that is used for joints 4 of the PC boards 1 and 2 to maintain airtightness and watertightness. And a joint gasket 5. Then, the joint gasket 5, which is a gasket for construction, is divided into an elastically deformable body 6, a thick portion 8, and a partition wall 1.
1, a communication hole 13, a flow hole 14, and a tube 15.

The elastically deformable body 6 is excellent in fire resistance, heat resistance, cold resistance, moisture resistance, chemical resistance, aging resistance, electrical insulation and the like as shown in FIGS. Extrusion molding using silicone rubber foam, height dimension 40m
m, a cross section of 32 mm in width is formed into an almost figure-eight shape, and the whole is formed in an L-shape, in the height direction (FIG. 2,
It functions to expand and contract in the vertical direction in FIG. 3 or FIG.
The elastically deformable body 6 has an upper portion in the height direction formed into a thick portion (6 mm in the present embodiment) 8 thicker than the thickness (4 mm in the present embodiment) of the peripheral wall 7 in the vicinity thereof.

The lower part of the elastically deformable body 6 is formed so as to protrude from a flat mounting seat 9 having the same thickness (6 mm in the present embodiment) as the thick portion 8. It is fixed, adhered, or removably adhered to the mounting groove 3 of the joining portion 2a formed by the peripheral portion 2 via an adhesive or an adhesive tape (not shown) before the application. As shown in FIG. 2, a lid 10 made of a silicone rubber foam is provided on both end surfaces of the elastically deformable body 6.
(In the present embodiment, a thickness of 2 to 3 mm) are adhered to each other, and this pair of lids 10 constitutes the elastically deformable body 6 in a substantially sealed hollow.

The partition 11 is integrally formed between both sides of the inside of the elastically deformable body 6 so as to form a pair of upper and lower hollow chambers 12 having a substantially turtle-shaped cross section in the height direction of the inside of the elastically deformable body 6. The partition 11 is formed to have the same thickness (4 mm in the present embodiment) as the thickness of the peripheral wall 7 in the vicinity, and is formed to be thinner than the thick portion 8. The communication hole 13 is pierced through the end of the partition wall 11 by a puncher or the like (not shown) before the lid 10 is bonded, and communicates with the pair of hollow chambers 12 to allow the flow of air indicated by an arrow.

As shown in FIG. 3, the flow hole 14 is formed by penetrating the lower part of the side wall of the elastically deformable body 6. As shown in the drawing, a flexible resin tube 15 made of synthetic resin is inserted into the flow hole 14, and a portable suction device 16 as a decompression means is detachably connected to the distal end of the tube 15. The operation of the portable suction device 16 causes the elastically deformable body 6 to move.
Air is exhausted from the entire hollow chamber 12 through the tube 15 to the portable suction device 16. Further, a valve 17 having a simple configuration is detachably attached to the tube 15, and the valve 17 controls the flow and stop of the air flowing through the tube 15. The other parts are the same as in the conventional example, and the description is omitted.

In the above configuration, when designing the exterior of the building using the PC boards 1 and 2, first, the tube 15 is inserted into the flow hole 14 of the elastic deformation body 6 shown in FIG. A portable suction device 16 is attached to the distal end of the tube 15, and a valve 17 is attached to the tube 15. Then, the portable suction device 16 is operated for about 3 to 5 seconds.

Then, air is exhausted from the entire hollow chamber 12 of the elastic deformable body 6 through the tube 15 to the portable suction device 16, and the elastic deformable body 6 is decompressed in the height direction and crushed.
(See FIG. 6 (b)). When the elastic deformable body 6 is decompressed and compressed in this manner, the valve 17 is closed, the decompressed state of the elastic deformable body 6 is maintained, and the portable suction device 16 is removed from the tube 15.

After the portable suction device 16 is removed, the beam-shaped PC board 2 is pulled in between a plurality of column-shaped PC boards 1 and set.
At this time, since the elastically deformable body 6 has a substantially flat state that is shorter than the predetermined dimension of the joint 4 and does not contact the joint 1a of the columnar PC plate 1 at all, the plurality of columnar PCs The beam-shaped PC board 2 can be set smoothly and easily between the boards 1 through the gaps, in other words, the joints 4.

When the beam-shaped PC board 2 is set, the valve 17
Is opened to release the flow restriction of the tube 15, and the decompressed and compressed state of the elastic deformable body 6 is returned to the original state. Then, air flows from the outside through the tube 15 into the entire hollow chamber 12 of the elastically deformable body 6, and the substantially flat elastically deformable body 6 expands in the height direction to join the columnar PC plate 1 to the joint. 1a is pressed accurately and resiliently, the joints 4 are sealed, and the exterior of the building is properly constructed (see FIG. 6 (c)). Thereby, the safety, airtightness, and / or watertightness of the building are sufficiently ensured.
Hereinafter, the above operation is repeated as necessary. The other construction work is the same as in the conventional example, and the description is omitted.

According to the above configuration, the elastic deformable body 6 is deformed into a form shorter than the predetermined dimension of the joint 4 before the setting of the beam-shaped PC board 2, so that the beam-shaped PC board 2 is pulled in from behind. Also,
Joint gasket 5 without contact with pillar-shaped PC board 1
Can be reliably prevented from being greatly bent and deformed in a state of side-down which is misaligned in the width direction (the left-right direction of FIG. 2, FIG. 3, or FIG. 4). Therefore, it is possible to remarkably simplify, smoothen, and facilitate the construction, shorten the construction and save labor, reduce the construction cost, and the like. In addition, the joint gasket 5 can be very effectively prevented from being damaged or dropped due to wear.

Further, since the joint gasket 5 is not misaligned and deformed into an abnormal shape at all, the safety of the building is improved.
Airtightness, watertightness, waterproofness, fireproofness, sound insulation, and sufficient vibration absorption can be greatly expected. The partition 11
Since the ratio of the height dimension / width dimension of each hollow chamber 12 is set to 1 or less, it is possible to extremely effectively prevent the elastically deformable body 6 from being depressurized and compressed in the width direction with a simple configuration.

In addition, the thick portion 8 is located near the peripheral wall 7 and the partition 11.
4 (a) and 4 (b) and FIGS. 5 (a) and 5 (b), as is apparent from the comparison between FIGS. 4 (a) and 4 (b) and FIGS. 5 (a) and 5 (b). In addition, it is possible to extremely effectively prevent the upper portion of the elastic deformation body 6 from jumping up (see the circle in FIG. 5B) during the decompression and compression. Hereinafter, this point will be described in detail. When the thick portion 8 is formed to have the same thickness as the thickness of the peripheral wall 7 in the vicinity, and when the upper hollow chamber 12 adjacent to the thick portion 8 is not substantially in the shape of a cross section, As shown in FIGS. 5 (a) and 5 (b), both sides of the upper portion of the elastically deformable body 6 jump up during the decompression and compression, and the compression size is largely insufficient.

On the other hand, according to the present embodiment, the thick portion 8 is formed thicker than the peripheral wall 7 in the vicinity to improve the strength and rigidity. Since the hollow chamber 12 has a substantially turtle-shaped cross section with a flat portion, FIG.
As shown in (a) and (b), even if the elastic deformable body 6 is decompressed and compressed, the upper center of the elastic deformable body 6 may be curved in a semicircular shape,
It is possible to effectively suppress and prevent the upper both sides of the elastic deformation body 6 from jumping. Therefore, the elimination of insufficient compressed dimensions can be greatly expected.

Further, since there is no need to increase the width of the elastically deformable body 6, there is no adverse effect on the thinning of the PC plates 1 and 2, the primary seal and backup material, and the depressurizing grooves of the PC plates 1 and 2. Has no effect. Further, the communication hole 13 communicates with the entire hollow chamber 12 of the elastic deformation body 6, and furthermore, the entire hollow chamber 12
Since the air is sucked by the portable suction device 16, the evacuation operation does not need to be performed many times, and the operation can be simplified and speeded up. Furthermore, since the flow hole 14 is formed in the lower part of the side wall of the elastic deformable body 6, in other words, near the maximum width of the elastic deformable body 6 at the time of decompression and compression, there is no hindrance to airtightness, watertightness and the like. There is no fear.

FIGS. 7 and 8 show a second embodiment of the present invention. In this case, the upper portion of the side wall of the elastically deformable body 6, in other words, the elastically deformable body 6 during compression under reduced pressure is used. Are formed in the vicinity of the maximum width. The other parts are the same as those in the above-described embodiment, and the description is omitted. It is clear that the present embodiment can expect the same operation and effect as the above embodiment.

Next, FIG. 9 shows a third embodiment of the present invention. In this case, a pair of joint gaskets 5, more specifically, a pair of elastic deformable bodies 6 are connected via a joint 18. So that they are connected in an almost L-shape. The joint 18 has fire resistance, heat resistance, cold resistance, moisture resistance, chemical resistance, aging resistance,
And an elbow main body 19 formed by extrusion using a silicone rubber foam having excellent electrical insulation properties.
The elbow main body 19 which can be expanded and contracted in the height direction is formed into a substantially eight-shaped cross section, and a pair of upper and lower insertion insertion ports 20 are integrally formed on both end surfaces thereof, respectively. The insertion openings 20 are respectively inserted into both open end faces of the elastically deformable body 6 to perform a connection function. The other parts are the same as those in the above-described embodiment, and the description is omitted.

In this embodiment, the same operation and effect as those of the above embodiment can be expected.
Are obliquely cut, and there is no need to bond the inclined ends of the pair of elastically deformable bodies 6 with an adhesive or the like. Therefore, the construction is significantly simplified, smoothed and facilitated.
It is possible to shorten the construction time, save labor, and reduce construction costs.

In the above-described embodiment, each hollow chamber 12 is formed to have a turtle-shaped cross section. However, if it is appropriately decompressed and compressed in the height direction, the cross-sectional shape of the lower hollow chamber 12 may be changed. It may be changed to the form. In the above embodiment, the building gasket is used as the joint gasket 5,
When used as another type of gasket or when the pressure is not reduced, the elastically deformable body 6 may have a substantially cylindrical rod shape by omitting the lids 10 on both end surfaces of the elastically deformable body 6. Further, in the above embodiment, the valve 17 is opened and the air is supplied from the outside to the tube 15. However, the pressure reducing means is a pump means also having an air pressure sending function, and the air is supplied from the pump means to the elastic deformable body 6. Can be supplied to the entire hollow chamber 12 through a tube 15.
