[0002] Expansion joints are used in the construction of building main structures, such as high-rise buildings, large public buildings, and multi-unit connected buildings. These structures require longitudinal or transverse expansion joints to divide the main structure due to exceeding structural length limits, settlement differences, or seismic requirements. Construction elevators are also necessary to facilitate the vertical transportation of personnel and materials.

This can easily lead to installation misalignment or stress imbalance. Furthermore, the adjustment of the attachment position of the construction elevator is limited. Traditional supports have a single positioning range, which makes it difficult to match the different lateral attachment positions of the elevator. Therefore, it is necessary to propose a construction elevator attachment support for expansion joints. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] like Figures 1-5 As shown, the present invention proposes an attachment bracket for an expansion joint construction elevator, which includes an L-shaped support plate 1 and a steel pipe 10. The L-shaped support plate 1 is provided with a sliding hole 101 and a locking hole 102. The L-shaped support plate 1 is threadedly connected to an embedded bolt 2, and the embedded bolt 2 is threadedly connected to a first locking nut 201. Both the L-shaped support plate 1 and the steel pipe 10 are equipped with a bracket locking assembly. The bracket locking assembly includes a T-shaped fixing plate 3 mounted on an L-shaped support plate 1, a first bolt 4 and a second nut 5, the first bolt 4 and the second nut 5 being threaded together, and the first bolt 4 and the second nut 5 being used to fix the T-shaped fixing plate 3 on the L-shaped support plate 1. A fixed horizontal plate 8 and a square plate 801 are fixedly connected to the steel pipe 10. The fixed horizontal plate 8 is slidably connected to the L-shaped support horizontal plate 1. The T-shaped fixing plate 3 and the fixing cross plate 8 are jointly installed with the second bolt 6, and the outer thread of the second bolt 6 is connected to the third nut 7.

[0017] Furthermore, during construction, the embedded bolts 2 are first fixed to the building structure. After adjusting its lateral position using the sliding holes 101 on the L-shaped support plate 1, it is locked in place by the first locking nut 201 to fix the basic installation position of the L-shaped support plate 1. Then, the T-shaped fixing plate 3 of the bracket locking assembly is installed on the L-shaped support plate 1. It is tightened by the first bolt 4 and the second nut 5 symmetrically arranged on the T-shaped fixing plate 3 to form a stable locking reference. Since the steel pipe 10 is fixed to the fixing plate 8 by the square plate 801, the fitting position of the steel pipe 10 can be adjusted by the sliding fit between the fixing plate 8 and the L-shaped support plate 1. After the position is calibrated, it is locked in place by the second bolt 6 installed together with the T-shaped fixing plate 3 and the fixing plate 8 and the third nut 7 with the outer thread, so that the steel pipe 10 can stably bear the adhesion force of the construction elevator.

[0018] The number of embedded bolts 2 is at least two, and the embedded bolts 2 are respectively inserted into the L-shaped support plate 1.

[0019] Furthermore, during construction, at least two embedded bolts 2 are first fixed to the building load-bearing structure on both sides of the expansion joint. Then, each embedded bolt 2 is inserted into the L-shaped support plate 1. The at least two embedded bolts 2 can distribute the construction elevator attachment load borne by the L-shaped support plate 1, avoid overload of a single screw, and provide a balanced and stable installation foundation for the L-shaped support plate 1. Subsequently, the position of the L-shaped support plate 1 can be fixed by using locking components.

[0020] Multiple locking holes 102 are provided at intervals along the length of the L-shaped support plate 1, and each locking hole 102 is adapted to the T-shaped fixing plate 3.

[0021] Furthermore, during construction, the installation position of the T-shaped fixing plate 3 is adjusted by sliding along the length of the L-shaped support plate 1 according to the width of the expansion joint or the attachment position of the construction elevator. The multiple locking holes 102 spaced apart on the L-shaped support plate 1 provide multiple installation options for the T-shaped fixing plate 3. After the T-shaped fixing plate 3 is adjusted to the target position, it is locked and fixed by utilizing the compatibility between the locking holes 102 and the T-shaped fixing plate 3, positioning and maintaining the T-shaped fixing plate 3 firmly, providing a reliable reference for subsequent connection with the fixing plate 8.

[0022] The L-shaped support plate 1 is provided with a sliding track extending along its length. There are two sets of T-shaped fixing plates 3. The bottom of the T-shaped fixing plate 3 is provided with a slider that matches the sliding track. The T-shaped fixing plate 3 slides on the L-shaped support plate 1 through the cooperation of the slider and the sliding track.

[0023] Furthermore, during construction, based on the required spacing of the construction elevator attachment, the two sets of T-shaped fixing plates 3 are pushed to slide smoothly on the L-shaped support plate 1 by the cooperation of the slider at the bottom of the T-shaped fixing plate 3 and the sliding track extending along the length direction on the L-shaped support plate 1. The matching structure of the sliding track and the slider can limit the sliding direction of the T-shaped fixing plates 3, prevent deviation, and ensure smooth sliding. The two sets of T-shaped fixing plates 3 can be adjusted to the target position independently or synchronously, providing a symmetrical and stable installation benchmark for subsequent connection with the fixing plate 8, thereby improving the overall force balance of the support.

[0024] The fixed horizontal plate 8 has a strip groove on one side facing the L-shaped support horizontal plate 1, and the end of the L-shaped support horizontal plate 1 has a sliding protrusion that matches the strip groove. The fixed horizontal plate 8 and the L-shaped support horizontal plate 1 are slidably connected through the cooperation of the strip groove and the sliding protrusion.

[0025] Furthermore, during construction, depending on the width of the expansion joint or the specific location requirements of the construction elevator attachment, the fixed horizontal plate 8 and the L-shaped support horizontal plate 1 are pushed to slide relative to each other. The strip groove on the fixed horizontal plate 8 and the sliding protrusion at the end of the L-shaped support horizontal plate 1 are matched and cooperated to effectively limit the relative movement direction of the two and avoid deviation or jamming during the sliding process. After being adjusted to a suitable position, it is locked and fixed to ensure that the connection between the two is stable, providing a reliable sliding adjustment foundation and structural support for bearing the attachment load of the construction elevator.

[0026] The square plate 801 is vertically fixed to the end of the fixed horizontal plate 8 away from the steel pipe 10. The end of the fixed horizontal plate 8 away from the L-shaped support horizontal plate 1 is fixedly connected to the connecting plate 9. The connecting plate 9 and the steel pipe 10 are welded and fixed. The square plate 801 is welded and fixed to the fixed horizontal plate 8.

[0027] Furthermore, during construction, the square plate 801 is first welded and fixed to the end of the fixed horizontal plate 8 away from the steel pipe 10. The square plate 801 can enhance the structural rigidity of the end of the fixed horizontal plate 8 and prevent it from bending and deforming under stress. Then, the connecting plate 9 is fixed to the end of the fixed horizontal plate 8 away from the L-shaped support horizontal plate 1. The connecting plate 9 serves as a transition connector to provide a stable welding reference for the steel pipe 10. Finally, the steel pipe 10 is welded and fixed to the connecting plate 9. Through the rigid connection formed by welding and the reinforcing effect of the square plate 801, the steel pipe 10 can stably bear the adhesion force of the construction elevator and ensure the overall stress stability of the support.

[0028] Both bolt 4 and bolt 6 are high-strength bolts with a nominal diameter of 14mm-20mm, and both bolt heads are equipped with anti-loosening washers.

[0029] Furthermore, during construction, prepare high-strength first bolt 4 and second bolt 6 with nominal diameters of 14mm-20mm, and install anti-loosening washers on the heads of each bolt. Then, insert the bolts with anti-loosening washers into the corresponding connection holes and tighten them. The high-strength bolts can withstand the large load generated by the attachment of the construction elevator, preventing the bolts from deforming or breaking under stress. The anti-loosening washers can effectively resist the loosening of bolts caused by construction vibration.

[0030] In this embodiment, the specific implementation method is as follows: during construction, at least two embedded bolts 2 are first fixed to the building load-bearing structure on both sides of the expansion joint. Each embedded bolt 2 passes through the L-shaped support plate 1 to distribute the load. After adjusting its lateral position with the help of the sliding hole 101 on the L-shaped support plate 1, it is locked and fixed by the first locking nut 201. Then, according to the attachment distance requirements of the construction elevator, the position is smoothly adjusted by the cooperation of the slider at the bottom of the two sets of T-shaped fixing plates 3 and the sliding track on the L-shaped support plate 1. The sliding track and the slider limit the offset. Combined with the multiple locking holes 102 set at intervals on the L-shaped support plate 1, the T-shaped fixing plate 3 provides multiple position selection. After adjusting to the target position, the T-shaped fixing plate 3 is tightened with a high-strength first bolt 4 and a second nut 5 with anti-loosening washers and a nominal diameter of 14mm-20mm to form a stable reference. Then push the fixed horizontal plate 8 and adjust its position by cooperating with the sliding protrusion at the end of the L-shaped support horizontal plate 1 through its strip groove to avoid offset and jamming. Then weld the square plate 801 to the end of the fixed horizontal plate 8 away from the steel pipe 10 to enhance the end rigidity. Fix the connecting plate 9 to the end of the fixed horizontal plate 8 away from the L-shaped support horizontal plate 1 as a transition reference. Weld the steel pipe 10 to the connecting plate 9 to fix it. Finally, the T-shaped fixing plate 3 and the fixing horizontal plate 8 are locked and fixed with a high-strength second bolt 6 and a third nut 7, which are equipped with anti-loosening washers and have a nominal diameter of 14mm-20mm. The high-strength bolts bear the load and prevent deformation, the anti-loosening washers resist vibration and prevent loosening, and the square plate 801 strengthens the connection with the welded rigidity, so that the steel pipe 10 can firmly bear the adhesion force of the construction elevator and ensure the overall stability of the support.
