Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings 1 to 5.
The positioning connecting device can be detachably connected with the curtain wall 1 and is convenient for adjusting the position of the curtain wall 1, so that the curtain wall 1 is attractive in installation, the U-shaped rod 4 on the curtain wall 1 is matched with the U-shaped groove 14 in the positioning connecting device, the initial positioning of the curtain wall 1 can be realized, the U-shaped rod 4 has a certain transverse moving space relative to the U-shaped groove 14 on the sliding block 13, the screw rod is rotated to drive the slide block 13 to move along the slide groove 10, so that the threaded hole 15 on the slide block 13 corresponds to the vertical groove 5 on the U-shaped rod 4 of the vertical groove 5, the curtain wall 1 is positioned at a proper position, so that match rather than adjacent curtain 1 about it, make the seam pleasing to the eye, later accomplish through bolt 16 and fix, curtain 1 is fixed on location connecting device this moment, later for the pleasing to the eye of curtain 1 installation, can also change the position of location connecting device for montant 3 through screw rod 8 for the seam crossing of adjacent curtain 1 is pleasing to the eye from top to bottom.
Further in order to increase the aesthetic property, the cross rod 2 is of an arc-shaped structure, the optimal radian of the cross rod 2 and the optimal radian of the curtain wall 1 are matched with the radian of the appearance of a building, and the aesthetic property can be further increased. After the curtain wall 1 is in plug-in fit with the U-shaped groove 14 on the sliding block 13 through the U-shaped rod 4, the curtain wall 1 is supported by the sliding block 13, and at the moment, the labor for supporting the curtain wall 1 can be released under the condition of ensuring the construction safety, so that the labor intensity is reduced. Then, the position of the slide block 13 is adjusted through the lead screw, so that the threaded hole 15 corresponds to the vertical groove 5, and then the bolt 16 passes through the threaded hole 15 and the vertical groove 5 to complete the fixed connection of the curtain wall 1 and the positioning connecting device. The length of the vertical slot 5 is larger than the diameter of the threaded hole 15, so that the bolt 16 can smoothly pass through the vertical slot 5 after being matched with the threaded hole 15. After a curtain wall 1 is installed, when the curtain walls 1 adjacent to the left and right of the curtain wall 1 are installed, the relative positions of the curtain walls 1 and the sliding blocks 13 and the relative positions of the two curtain walls 1 are adjusted, so that the joint is attractive. Two screw rods 12 on one L-shaped plate 11 independently control corresponding slide blocks 13, so that the adjustment is convenient. The U-shaped rod 4 has a certain transverse moving space relative to the U-shaped groove 14, so that the flexibility of adjustment is further increased; after installing a curtain 1, when installation and its upper and lower adjacent curtain 1, for the convenience of adjusting the distance of two-phase adjacent curtain 1 under the mountain makes the seam pleasing to the eye, can carry out vertical slip along montant 3 through rotating screw 8 drive square sleeve 6 for location connecting device reciprocates together rather than fixed connection's curtain 1.
In order to facilitate the rotation of the screw rod 12, a fixed sleeve 18 is fixedly connected to the screw rod, and a plurality of deflector rods 19 in an annular array are fixedly connected to the fixed sleeve 18, so that the screw rod 12 can be rotated conveniently through the deflector rods 19; in order to limit the square sleeve 6 to slide vertically along the vertical rod 3, the left end and the right end of the vertical rod 3 are provided with elongated slots 20, and the inner wall of the square sleeve 6 on each vertical rod 3 is fixedly connected with a convex block 21 in sliding fit with the corresponding elongated slot 20, so that the square sleeve 6 is driven to move vertically by a screw 8 rotationally connected with the supporting plate 7. When the curtain wall 1 needs to be disassembled, the bolts 16 are only screwed out, and then the curtain wall 1 can be made to fall out of the limit of the U-shaped groove 14.
