JP 2021-155975 Publication

Such a cold vent construction method, as described in Patent Document 1, is carried out by lifting a glass plate together with the sash and pulling in or pushing out the apex along the building wall surface. However, a specific device for performing the cold vent construction method is not described in Patent Document 1. When performing the cold vent construction method, the sash must be pulled in or pushed out, which is time-consuming at the construction site. It is also desired to be able to bend the glass plate in advance even when it is not suspended along the wall of a building, such as at a location other than the construction site.

The present invention has been made in consideration of the above-mentioned prior art, and an object of the present invention is to provide a cold vent device that can perform a cold vent construction method even at a location other than a construction site.

In order to achieve the above object, the present invention provides a device main body to be disposed on one side of a cold vent glass unit consisting of a rectangular glass plate and a sash covering the periphery of the glass plate, and a device attached to the device main body. a force applying device for applying a force to a bent corner that is one corner of the cold vent glass unit; a transmission member extending from the force applying device toward the vent corner; and a transmission member. A tip portion that is located at the tip of the device and contacts or engages with the vent corner portion, and a portion other than the vent corner portion that is mutually connected to maintain a constant distance between the device body and the cold vent glass unit. To provide a cold vent device characterized by comprising a fixing unit for fixing the cold vent device.

Preferably, the device main body is formed of a frame along the outer edge of the cold vent glass unit.

Preferably, the transmission member extends along a side surface of the cold vent glass unit.

Preferably, the device main body includes a ring-shaped connecting portion to be connected to the sling.

The present invention is equipped with a force applying device that applies force to the vent corner, and since the distance between the main body of the device and the cold vent glass unit is constant in parts other than the vent corner, the force applying device is not required. By using this, only the bent corners can be bent. This operation can be performed regardless of the location, so it can be performed at any location, even if it is not at the construction site or along the wall of the building. Note that bending the bent corner portion refers to moving the bent corner portion in the longitudinal direction of the transmission member.

Further, since the device main body is formed of a frame along the outer edge of the cold vent glass unit, the cold vent glass unit in a bent state can be stored while being held in the device main body. During storage, since the main body of the device is along the outer edge of the cold vent glass unit, the cold vent glass unit can be efficiently protected.

In addition, since the transmission member extends along the side of the cold vent glass unit, even after multiple cold vent glass units are placed on the building wall, the transmission member can be inserted through the gap between adjacent cold vent glass units. This allows you to make fine adjustments to the bending of the cold vent glass unit.

Furthermore, by providing a connecting portion on the main body of the device, it can be connected to a sling used when lifting the device along the wall of a building, improving workability on site.

As shown in FIG. 1, a cold vent device 1 according to the present invention is used to perform a cold vent construction method on a cold vent glass unit 2. The cold vent glass unit 2 is formed of a rectangular glass plate 3 and a sash 4 covering the periphery of the glass plate 3. When performing the cold vent construction method, one corner of the cold vent glass unit 2, the vent corner 2a, is applied in one direction, and the vent corner 2a is moved in the direction of the applied force. Such movement of the vent corner 2a may be referred to as the cold vent glass unit 2 being bent. Specifically, the glass plate 3 is bent by the applied force, and the sash 4 is also bent accordingly (or the joints (corners) of adjacent sashes are rotated and followed). Note that any type of glass plate 3 to which the cold vent method can be applied may be used as the glass plate 3, and single-pane glass, laminated glass, and double-glazed glass are also applicable. The sash 4 is made of metal (for example, aluminum). Actually, an intermediate material (not shown) such as rubber, sponge, or sealing material is placed between the glass plate 3 and the sash 4 to ensure watertightness.

The cold vent device 1 includes a device main body 5, and the device main body 5 is arranged on one side of the cold vent glass unit 2. The apparatus main body 5 has a fixing unit 6 for fixing the apparatus main body 5 to the cold vent glass unit 2. Specifically, for example, the fixing unit 6 is a plate body having a through hole 6a extending from the device main body 5 toward the cold vent glass unit 2. A through hole 7 is also formed in the cold vent glass unit 2 at a position corresponding to the through hole 6a. As shown in FIG. 2, the apparatus main body 5 is fixed to the cold vent glass unit 2 via the fixing unit 6 by inserting the bolts 6b into these through holes 6a and 7. Thereby, the distance between the apparatus main body 5 and the cold vent glass unit 2 is maintained constant. The fixing unit 6 is formed in a portion other than the vent corner 2a. Here, the vent corner 2a is one corner of the cold vent glass unit 2 as described above, but it also includes the side that includes this corner and is bent by applied force. Therefore, as shown in the example shown in the figure, even if the fixing unit 6 is located along the side including the vent corner 2a, it is not affected by bending due to applied force (apart from the vent corner 2a and at the corner next to it). may be formed at a nearby location). That is, the vent corner portion 2a includes not only the corner portion of the cold vent glass unit 2, but also the front and back surfaces and side surfaces of the cold vent glass unit 2 that are affected by bending by the cold vent construction method.

A force applying device 8 is attached to the device main body 5. The force applying device 8 may be removably attached to the device main body 5, or may be fixed. This force applying device 8 is for applying force to the vent corner 2a in at least one direction. A transmission member 9 extends from the force applying device 8 toward the vent corner 3a. A distal end portion 10 that abuts or engages with the vent corner portion 2a is disposed at the distal end of the transmission member 9. In the examples shown in FIGS. 1 to 4, the tip portion 10 is a disc-shaped pad that comes into contact with the vent corner portion 2a. As shown in FIG. 2, when the device main body 5 is fixed to the cold vent glass unit 2, the tip 10 comes into contact with the vent corner 2a (specifically, the vent corner 2a and the surface of the sash 4 on the device main body 5 side). come into contact with The force applying device 8 is an actuator, and when the force applying device 8 is activated, the transmission member 9 is moved in the direction of the cold vent glass unit 2, and the tip 10 applies force to the vent corner 2a in the applying direction. do. Thereby, as shown in FIG. 3, the cold vent glass unit 2 is bent in the applied direction.

As described above, the device main body 5 is equipped with a force applying device 8 that applies force to the vent corner 2a, and furthermore, the device main body 5 and the cold vent glass unit 2 are separated from each other in a portion other than the vent corner 2a. Since the distance is constant, only the bent corner 2a can be bent by using the force applying device 8. This operation can be performed regardless of the location, so it can be performed at any location, even if it is not at the construction site or along the wall of the building. For example, the cold vent glass unit 2 may be bent in a horizontal state, or it may be bent by remote control of an actuator while the cold vent glass unit 2 is in a vertical direction while being suspended along a building wall. good. In the examples shown in FIGS. 1 to 4, there is only one bent corner 2a, but it is also possible to bend both corners at the same time, using the diagonal corner as the bent corner 2a.

Here, the device main body 5 is formed of a frame extending along the outer edge of the cold vent glass unit 2. That is, the device main body 5 is also formed in a rectangular shape like the sash 4. By using a frame, it is possible to place the device with the main body 5 facing down. Thereby, the cold vent glass unit 2 in a bent state can be stored while being held in the apparatus main body 5. Since the device main body 5 is along the outer edge of the cold vent glass unit 2 during storage, the device main body 5 plays a role as a protective material and can efficiently protect the cold vent glass unit 2.

As shown in FIG. 4, the cold vent glass unit 2 bent in this manner is lifted up by the sling 12 via the connecting portion 11 and transported so as to be positioned on the building wall. Therefore, the device main body 5 is provided with a ring-shaped connecting portion 11 to be connected to the sling 12. By providing the connecting portion 11 in the device main body 5 in this manner, it can be connected to the sling 12 used when hoisting the device along the wall surface of a building, improving workability on site. Note that if a clamp is attached to the tip of the sling 12, this connecting portion 11 is not necessary, but as shown in FIG. It would be convenient if there was a connecting part.

Another example of the cold vent device 1 is shown in FIGS. 5 to 8. In this example, the fixing unit 6 is different from the example described above. The fixing unit 6 is for fixing the apparatus main body 5 to the cold vent glass unit 2 and also for maintaining a constant distance between the apparatus main body 5 and the cold vent glass unit 2. For this purpose, a spacer 6c may be further provided as part of the fixing unit 6. The spacer 6c has a shape that follows the frame shape of the sash 4, and is formed in a shape that excludes the vent corner 2a. In the illustrated example, the spacer 6c is formed in an L-shape excluding the side including the bent corner 2a. By disposing such a spacer 6c between the apparatus main body 5 and the cold vent glass unit 2, the apparatus main body 5 is fixed at a constant distance from the cold vent glass unit 2 by the fixing unit 6. Specifically, the device main body 5 has a mounting piece 6d, and this mounting piece 6d is fixed to the spacer 6c. The spacer 6c also has a mounting piece 6e, and this mounting piece 6e is fixed to the cold vent glass unit 2. By using such an L-shaped spacer 6c, as shown in FIG. 6, a gap is formed between the vent corner 2a and the device main body 5 by the spacer 6c. .

Further, in this example, the transmission member 9 extends along the side surface of the cold vent glass unit 2. The tip portion 10 is formed in such a shape as to sandwich the cold vent glass unit 2 (see FIG. 9). Specifically, the tip portion 10 is formed of a presser piece 10a protruding from the transmission member 9 and a presser member 10b having a substantially L-shaped cross section. As shown in FIG. 10, the presser piece 10a is brought into contact with one surface of the cold vent glass unit 2 (the surface on the device main body 5 side), the presser member 10b is arranged on the distal end side of the transmission member 9, and the bolt 10c The presser member 10b is fixed to the transmission member 9 by. Thereby, the tip portion 10 is engaged with the bent corner portion 2a.

At this time, as shown in FIG. 6, the transmission member 9 extends along the side surface of the sash 4, and in this state, the tip portion 10 is engaged with the bent corner portion 2a. Then, by applying a force in the direction of pulling the force applying device 8 (the direction of moving the vent corner 2a toward the device main body 5 side), the transmission member 9 is moved in the direction of the device main body 5, and the tip portion 10 is moved toward the vent corner 2a. 2a is applied in the applying direction (direction of the device main body 5). Thereby, as shown in FIG. 7, the cold vent glass unit 2 is bent in the applied direction. In addition, if the tip part 10 is configured as shown in the figure, it is also possible to use it by applying force in the direction of pushing the force applying device 8 (in the direction of moving the vent corner 2a to the side opposite to the device main body 5). .

By extending the transmission member 9 along the side surface of the sash 4 in this way, the following effects can be achieved. A plurality of cold vent glass units 2 bent by the cold vent construction method are attached to a building wall and arranged side by side. At this time, if the transmission member 9 extends along the side surface of the cold vent glass unit 2, the transmission member 9 can be pulled out and the apparatus main body 5 can be removed from the cold vent glass unit 2 even after the cold vent glass units 2 are arranged side by side. be able to. Specifically, if the worker removes the bolt 10C on the building frame side from the building side and further removes the holding member 10b, the device main body 5 can be pulled out together with the force applying device 8. Furthermore, even after a plurality of cold vent glass units 2 are arranged on a building wall, by inserting the transmission member 9 through the gap between adjacent cold vent glass units, the device main body 5 can be reattached and the cold vent glass units 2 can be reattached. It can be bent and the bending can be finely adjusted. Note that the transmission member 9 extending along the side surface of the cold vent glass unit 2 means that the transmission member 9 and the side surface of the cold vent glass unit 2 may be in contact with each other, or may be separated by a slight gap. These may be parallel.

In order to obtain the same effect, as shown in FIG. You may. In this case, as shown in FIG. 12, the transmission member 9 may be moved along the cold vent glass unit 2 to accommodate the protrusion 10e within the notch 10d. Thereby, the tip portion 10 is engaged with the bent corner portion 2a. In this engagement operation, the transmission member 9 only needs to be placed along the side surface of the cold vent glass unit 2, so even after a plurality of cold vent glass units 2 are arranged on the wall of the building, the transmission member 9 can be inserted into the gap between the adjacent cold vent glass units 2. You can put in and take out smoothly. Further, the distal end portion 10 in the example of FIG. 11 can respond to the force applied by the force applying device 8 in the pushing direction and the pulling direction, as in the example of FIG.

Furthermore, as shown in FIGS. 13 and 14, a similar effect can be obtained by providing a through hole 10f at the tip of the transmission member 9, and attaching a holding member 10g having a substantially C-shaped cross section with right angles to a bolt 10h. It may be attached to the tip of the transmission member 9 via. Thereby, the tip portion 10 is engaged with the bent corner portion 2a. At this time, the holding member 10g is placed on the surface of the cold vent glass unit 2 opposite to the device main body 5. Even with such a structure, the transmission member 9 can be slid along the side surface of the cold vent glass unit 2 by removing the bolt 10h from the building frame. Therefore, even after a plurality of cold vent glass units 2 are arranged on the wall of a building, the transmission member 9 can be smoothly inserted and removed from the gap between adjacent cold vent glass units 2. Further, the tip portion 10 in the example shown in FIG. 13 can respond to the force applied by the force applying device 8 in the pushing direction and the pulling direction.

FIG. 15 shows a cold vent device 1 according to the present invention as an example of one having a tip end 10 as shown in FIGS. 13 and 14. As shown in FIG. In addition, FIG. 16 is a diagram when the longitudinal direction part of FIG. 15 is viewed from the front, and FIG. 17 is a diagram when the lateral direction part is viewed from the front. In this example, a jack is used as the force applying device 8. Although any type of jack is acceptable, the illustrated example shows a screw-type pantograph jack. This example also shows a fastener 14 for attaching the cold vent glass unit 2 to the building frame. The fastener 14 is fixed to the sash 4, and is fixed to a fastener (not shown) on the building frame side via a bolt or the like. Furthermore, by forming the holding member 10g into a substantially C-shaped cross section with right angle corners, it can also serve as a fastener. Other configurations, operations, and effects are similar to the examples shown in FIGS. 5 to 8. When the vehicle is jacked up in the state shown in FIG. 15, a force in a pulling direction is applied to the vent corner 2a, as shown in FIGS. 18 and 19. That is, the vent corner 2a is moved (bent) in the direction of the measure body 5. Even with such a cold vent device 1, the cold vent glass unit 2 can be bent.
