Detailed Description
The technical scheme of the utility model is described in detail below through the drawings, but the protection scope of the utility model is not limited to the embodiments.
Example 1:
as shown in fig. 1 to 4, the construction structure for hoisting large-size prefabricated cantilever plates on a high-rise building roof of the utility model comprises: parapet 1 and a plurality of L-shaped pre-members; the parapet wall 1 is provided with a plurality of embedded threaded sleeves 2; the L-shaped pre-member comprises a fixing plate 3 and a cornice plate 5, wherein a plurality of fixing holes 4 are formed in the fixing plate 3, and the positions of the fixing holes 4 are matched with the positions of the pre-buried threaded sleeves 2; the fixing holes 4 on the L-shaped pre-members are sequentially connected and fixed with the embedded threaded sleeves 2 on the parapet through anchoring pieces 7.
As shown in fig. 1 to 4, after the anchor member 7 is fixed, a grouting area 8 is arranged outside the fixing hole 4, and a plastering layer 9 is arranged outside the grouting area 8. A plurality of lifting holes 6 are reserved in the cornice 5, so that the L-shaped prefabricated member can be lifted to the corresponding parapet 1 through the tower crane. After the anchoring piece 7 is fixed, the lifting hole 6 in the cornice 5 is plugged by grouting, a grouting area 8 is obtained, and a plastering layer 9 is arranged on the outer side of the grouting area 8. The outer end of the cornice 5 is provided with a stop bar 10 which is as high as the thickness of the plastering layer 9. In the implementation process, the cornice plates 5 on two adjacent L-shaped pre-members are provided with a seam, and the seam is provided with a waterproof layer.
In the specific implementation process, the specific construction steps of the construction structure for hoisting the large-size prefabricated cantilever plates of the high-rise building roof are as follows:
(1) The construction of the reinforced concrete parapet 1 is finished firstly, the parapet 1 is 1800mm in height and 200mm in wall thickness, then a pre-buried threaded sleeve 2 is arranged at a preset position on the parapet 1, the inner diameter of the pre-buried threaded sleeve 2 is 30mm, the depth is 100mm, and the position corresponds to a fixing hole 4 on a subsequent L-shaped pre-member. The horizontal spacing of two adjacent embedded threaded sleeves 2 is 800mm, the vertical spacing is 800mm, the waterproof construction of the roof is not affected, and the distance between the lower row of threaded sleeves and the ground is not less than 600mm.
(2) Manufacturing an L-shaped pre-member: the L-shaped pre-member consists of a fixing plate 3 and a cornice plate 5, and fixing holes 4 are reserved at specific positions on the fixing plate 3 and correspond to the embedded threaded sleeves 2 on the parapet 1. The thickness of the fixing plate 3 is 200mm, the length is 1800mm, and the width is 1600mm; the cornice board 5 is 5200mm thick, 2500mm long and 1600mm wide, and 45-degree angle is added at the corner to match the cornice board 5. In order to prevent construction errors from causing non-correspondence of hole positions, the aperture of the fixed hole 4 is 70mm; and a hoisting hole 6 is reserved on the cornice 5, the aperture corresponds to the lifting appliance of the tower crane, and the hole depth is 80mm.
