Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a thin-wall shear wall attached wall force unloading device. Background Art

[0002] During the construction of super high-rise buildings, large vertical transportation equipment is required for the transportation of materials, especially tower crane transportation equipment, which needs to be attached to the core tube shear wall and climb along with the construction height of the super high-rise building. The core tube shear wall mainly bears the vertical and horizontal forces transmitted to the wall-attached embedded parts by the tower crane's own weight and the lifting weight. However, the thickness of the super high-rise core tube shear wall structure tends to gradually decrease with the increase of the building height. After the tower crane climbs to a certain height, the thickness of the shear wall at the wall-attached position is relatively thin and cannot withstand the horizontal force transmitted by the tower crane to the wall.

DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0020] like Figures 1 to 3 As shown, a thin-wall shear wall attached to the wall unloading device includes a wall-attached embedded part 1, an embedded base 2, and a unloading frame 3.

[0021] The wall-attached embedded part 1 includes a front embedded steel plate 11 and a back embedded steel plate 12 which are parallel to each other. A plurality of first embedded rods 13 which are parallel to each other and evenly distributed are welded between the front embedded steel plate 11 and the back embedded steel plate 12, and the first embedded rods 13 are perpendicular to the front embedded steel plate 11 and the back embedded steel plate 12 respectively.

[0022] The embedded base 2 includes an upper embedded steel plate 21 and a lower embedded steel plate 22 which are parallel to each other. A plurality of second embedded rods 23 which are parallel to each other and evenly distributed are welded between the upper embedded steel plate 21 and the lower embedded steel plate 22 , and the second embedded rods 23 are perpendicular to the upper embedded steel plate 21 and the lower embedded steel plate 22 , respectively.

[0023] The force unloading frame 3 includes a horizontally placed I-beam 31 and a right-angled triangular steel structure horn 32 . The steel structure horn 32 is formed by obliquely cutting the I-beam along the diagonal direction. A right-angled side of the steel structure horn 32 is welded to the top of the I-beam 31 .

[0024] The wall-attached embedded part 1 is embedded in the thin-walled shear wall 100, the embedded base 2 is embedded in the adjacent floor slab 200 below the wall-attached embedded part, one end of the force unloading frame 3 is welded to the back of the wall-attached embedded part 1, the bottom end of the force unloading frame 3 is welded to the top of the embedded base 2, and the front of the wall-attached embedded part 1 is welded with a wall-attached ear seat 4.

[0025] The specific structure of the welding of the force unloading frame 3 with the wall-attached embedded part 1 and the embedded base 2 is as follows: the other right-angled side of the steel structure horn 32 and the head end of the I-beam 31 are welded to the back of the wall-attached embedded part 1, and the bottom end of the I-beam 31 is welded to the top end of the embedded base 2.

[0026] In order to improve the firmness of the load unloading frame, a plurality of rectangular first ribs 33 are welded between the flange and the web of the I-beam 31 , and a plurality of rectangular second ribs 34 are welded between the top of the I-beam 31 and the steel structure horn 32 .

[0027] In order to meet the demand for unloading the wall-attached embedded component, the top of the steel structure horn 32 is higher than the back center of the wall-attached embedded component 1.

[0028] In order to ensure the stability of the connection between the force unloading frame 3 and the adjacent floor slab below the wall-attached embedded component, the bottom end of the force unloading frame 3 is simultaneously welded to a plurality of embedded bases 2 arranged in sequence along the length direction of the force unloading frame 3 .

[0029] The front of the wall-attached embedded part 1 is flush with the outer side of the thin-walled shear wall surrounding the wall-attached embedded part 1, and the back of the wall-attached embedded part 1 is flush with the inner side of the thin-walled shear wall surrounding the wall-attached embedded part 1. The top of the embedded base 2 is flush with the top of the floor slab surrounding the embedded base 2, and the bottom of the embedded base 2 is flush with the bottom of the floor slab surrounding the embedded base 2, which is convenient for later decoration and does not require the removal of the embedded base 2. After the tower crane is removed, it is only necessary to cut the weld between the force unloading frame and the wall-attached embedded part 1 and the embedded base 2, and then grind the surface of the wall-attached embedded part 1 and the embedded base 2. It is not necessary to remove the wall-attached embedded part 1 and the embedded base 2, and it will not damage the cast walls and floor slabs.
