Abstract

PROBLEM TO BE SOLVED: To increase implantation strength for not only bearing the vertical load of a curtain wall, but also firmly bearing both of an out-of-plane load and an in-plane load, expand a scope for general-purpose applications, allow mass production as well as the application of small sizes and light weight for reducing the cost of members, and further allow setting and adjustment works or the like at a construction site for improving workability. SOLUTION: A pair or a plurality of pairs of upper and lower burial legs 6 and 7 to be embedded in a curtain wall are projected from the base end of a hollow arm 1 and, then, vertical holes are drilled through the burial legs 6 and 7 to joint a vertical anchor threaded bar 10. Also, a boss part 11 is projected from the end of the arm 1, and formed to have a vertical screw hole. Then, a vertical bolt 13 is passed through the vertical screw hole from an upper position so as to be adjustable in height, and tightened.

In this case, with respect to the vertical holes 8 and 9 formed in the pair of upper and lower embedded legs 6 and 7 in the step 5, the upper and lower or one of the vertical holes is made into the screw hole a and the vertical anchor screw 10 is screwed. The lock is performed by a nut 26 screwed to the longitudinal anchor thread, and except for this point, it is the same as the case of 5., so that the other description is also omitted.

FIG. 21 and FIG. 22 show other fasteners for curtain walls when used below the curtain wall. 21 and 22, E is a stud, B is a receiving metal, C is a PCa curtain wall having the stud, D
Is a steel girder to which the receiving hardware is fixed. Receiving hardware B
Is made of ductile cast iron. An erect receiving plate 42 having a receiving hole 43 in the center is erected from a front edge of a mounting plate 40 having two mounting holes 41 arranged side by side. Left and right side plates 44 are continuously provided on both side edges of the upright receiving plate 42. Two studs E are stuck at both lower corners of the PCa curtain wall C, respectively, so that the tip ends protrude. Further, two right and left receiving plates 35 are welded to the upper flange 34 of the steel girder D so as to correspond to the studs E, and reinforcing plates are provided on the lower surface and the upper flange 34 of these receiving plates, respectively. 36 is reinforced to reinforce each receiving plate 35, and furthermore, the pedestals 45 are welded on both the receiving plates 35 to the upper flange 34, and the receiving hardwares B are respectively mounted on the both pedestals. The bolt and nut 46 and the washer 47 passed through the long hole 41 are temporarily fixed. And PCa
In setting up the curtain wall C, the tip end of each stud E is inserted into a receiving hole of the upright receiving plate 42 of each receiving metal B.
43, and temporarily fixed with nuts 48 and washers 49. Next, the position of each receiving metal B is adjusted, that is, the installation of the PCa curtain wall C is adjusted, and the bolts / nuts 46 and the nuts 48 are fully tightened. Although FIGS. 21 and 22 show the case where the PCa curtain wall C is used at both lower corners, the PCa curtain wall C may be used at both upper corners in the same manner. In either case, the PCa curtain wall C can be used for out-of-plane and in-plane load receiving.

The above fasteners 1 to 7 are:
All can be used for the upper part and the lower part of the curtain wall by a simple change such as the vertical change of the arm 1, the vertical anchor thread 10 and the stud E in the latch A, the stud B and the stud E. Therefore, these may be arbitrarily selected and used in combination.

[0019]

According to the first, second, third, fourth and fifth aspects of the present invention, since the latch has the above-described configuration, the vertical anchor screw 10 is used to cut the curtain wall. It can be buried precisely in the corners, increasing the degree of fixation, suppressing the occurrence of cracks in the concrete of the curtain wall, and greatly increasing the bearing strength,
Moreover, since the directionality of the vertical anchor thread 10 enhances the planting strength, the planting strength can be remarkably increased as compared with the conventional one, and not only the vertical load receiving of the curtain wall, but also out of plane, The in-plane load can also be strongly received.
In addition, the latch can be arbitrarily used in the upper corner portion and the lower corner portion of the curtain wall by the above-described configuration, and is used by being individually planted for each corner portion. Since there are few conditions for mounting to a curtain wall, it can be applied to various curtain walls such as a heavy-weight curtain wall and curtain walls of various shapes, and versatility can be enhanced. Therefore, mass production becomes possible, miniaturization and weight reduction can be achieved, and member costs can be reduced. Furthermore, downsizing and weight saving are convenient for transportation and handling, and setting and adjustment at an installation site can be facilitated, and workability can be improved.

In addition, according to the fifth aspect of the present invention, with the above-described configuration, it is possible to enhance the connection between the hook and the receiving metal with a simple structure.
