Description

[Detailed Description of the Invention] (Industrial Field of Application) The curtain wall cap connection device according to this invention relates to an improvement in the part that connects the caps provided at the upper end of the curtain wall covering the outer wall of a building.

(Prior Art) When constructing a building, it is common practice to attach a curtain wall as shown in FIGS. 9 to 11 to the outer periphery of a frame constructed from a steel frame.

This curtain wall has vertical mullions 1 and 1.
and blinds 2, 2 extending in the lateral direction are assembled in a checkerboard pattern, and glasses 3, 3 and light shielding plates 4, 4 are supported inside thereof.

At the top end of such a curtain wall, there is a 12th
By installing a cap 5 as shown in the figure, the appearance of the upper end of the curtain wall is adjusted, and rainwater is prevented from flowing into the hollow mullions 1 and the upper surface of the mullions 2.

By the way, as mentioned above, in the case of a cap that is attached to the upper end of a curtain wall, extruded aluminum material cut into lengths of several meters is used, so the ends of adjacent caps are placed at the construction site. Therefore, it is necessary to make a watertight connection.

For this reason, conventionally, an appropriately bent plate was installed at the site below the connecting part of the kasagi, and caulking material was poured onto this plate to connect the ends of adjacent kasagi in a watertight manner. was.

(Problem that the invention aims to solve) However, when connecting the ends of adjacent capboards in a watertight manner as described above, not only is it troublesome to process the plates on site, but the caulking material also prevents water from leaking. If the sealing function is impaired, water leaks immediately below the cap, which is not desirable.

Japanese Utility Model Application Publication No. 54-37918 describes a connection joint that has a gutter-like upper surface and can drain rainwater leaking from the connection part of the parapet cover to the outside. In the case of connection joints, the parapet cover and the connection joint cannot be handled as one, which not only complicates parts management, but also makes it troublesome to attach the connection joint to a predetermined location on site.

In addition, rainwater leaking from the connection part of the parapet cover flows through the groove on the top surface of the connection joint and flows down to the top surface of the middle plate of the parapet cover, but since this middle plate is flat, it flows onto the top surface of the middle plate. There is a possibility that the rainwater flowing down will flow in the width direction of this middle board and flow into the inside of mullion 1 or the top surface of mullion 2, and if it does, the rainwater will leak into the room from unexpected parts. This is not desirable as it may cause discharge.

The curtain wall cap connection device of the present invention eliminates all of the above-mentioned disadvantages.

(Means for Solving the Problems) The curtain wall cap connection device of the present invention comprises a pair of caps that are to be connected to each other, and a plate provided in a state that is stretched between the pair of caps. and a caulking material filled in a space surrounded by this backing board and the pair of caps.

The above-mentioned cap has first and second hanging walls that are provided downward from both end edges of the top plate that slopes in one direction, and a wall that extends from the inner surface of each hanging wall toward the center of the cap. a pair of horizontal wall portions formed by a pair of horizontal wall portions, first and second groove-shaped portions facing each other and formed between the upper surfaces of both horizontal wall portions and the lower side portions of both ends of the top plate portion; A groove is formed in the upper surface of the horizontal wall portion of the inner surface of the first hanging wall provided on the lower side of the plate portion, extending in the length direction of the cap.

Further, the above-mentioned backing plate is slidable in the first and second groove-shaped portions formed on the base plate inclined in one direction and on both ends in the length direction of the base plate, respectively, similar to the above-mentioned Kasagi. a pair of vertical walls formed by folding up both widthwise edges of the substrate portion in an upward direction; A hanging wall part is formed by bending the lower end edge of the part downward, and its lower end is inserted into the concave groove of the above-mentioned cap, and a part corresponding to any part of the above-mentioned cap. The cap has a long hole extending in the length direction of the cap, and the cap is inserted through the long hole and screwed into a screw hole formed in any part of the cap to connect the cap to the cap. ,
The cap is only able to move slightly in the lengthwise direction, and as it moves, a portion of the cap is connected to one end of the cap so that it can move in and out.

Furthermore, the above-mentioned caulking material is applied by fitting the above-mentioned caulking board over the inside of the end of one of the adjacent caps to be connected and the inside of the end of the other caps. It is injected and solidified onto the base plate of the plate.

(Function) In the case of the present invention configured as described above, the plate is stored inside one of the pair of caps to be connected during transportation of the caps, and the caps are connected to each other at the site. When connecting the caps to each other, pull them out from the inside of one of the caps and pass them between the two caps.

Therefore, the cap and the plate can be handled as one unit, making parts management easier, and the plate will not be damaged during transportation. Furthermore, by pulling out the plate from one of the caps to the extent that the screw can move inside the elongated hole, the plate can be correctly spanned between the pair of caps to be connected.

Furthermore, if the water-sealing function of the caulking material is impaired, rainwater that has entered through the gaps between the edges of the capboard will flow over the base of the board and be discharged, but it will leak from the connections between the capboards and cause damage to the caps. All of the rainwater that has flowed on the base of the board, except for the part that flows directly from the discontinuous part of the kasagi, flows into the groove, flows only in the length direction of the kasagi along this groove, and flows between the kasagi. is discharged from the discontinuity that exists at the connection of the For this reason, it is possible to reliably prevent rainwater leaking from the joints between the caps from flowing into the inside of the mullion or the top surface of the mullion.
