Description

Technical Field

[0001] The invention relates to the technical field of attachment connection structures, and more specifically to a non-standard attachment connection structure for a building construction hoist. Background Art

[0002] A construction elevator is a construction machine that uses a transmission device to make the cage move vertically or tilted to transport construction personnel, equipment or materials. It is mainly used for the interior and exterior decoration of high-rise buildings, the construction of bridges, chimneys and other buildings. Compared with other lifting mechanisms, construction elevators do not require a separate machine room or shaft, and the structure is stable, safe and reliable. It also has significant advantages in reducing the labor intensity of construction personnel and speeding up work efficiency. As the height of the building increases, the construction elevator must also rise accordingly. When its height exceeds the specified independent height, it must be connected to the building structure through an attachment device at a certain distance to ensure the rigidity and stability of the fuselage. Construction elevators are usually called construction elevators, but the definition of construction elevators is broader, and construction platforms also belong to the construction elevator series. A simple construction elevator is composed of a car, a drive mechanism, a standard section, an attached wall, a chassis, a fence, an electrical system, etc. It is a construction machine that is often used to carry people and goods in construction. Due to its unique box structure, it is both comfortable and safe to ride. Construction elevators are usually used in conjunction with tower cranes on construction sites. The general load capacity is 1-3 tons and the operating speed is 1-63M / min.

[0003] There are three main common methods for connecting construction elevator attachment frames to buildings. One is that the construction elevator attachment frame is directly fixed to the floor slab of the frame structure building by through-wall bolts; the second is to directly connect the wall-attached support of the construction elevator attachment rod to the wall with through-wall bolts; the third is to directly embed a pad on the wall and weld the wall-attached support directly to the embedded pad.

[0004] At present, the existing attachment connection structure has poor stability in the connection structure between the structure and the wall, and between the attachment rods, poor seismic performance during support, uneven force on the support will cause disadvantages in different directions, and it is not convenient to dismantle the connection structure after the construction is completed. Therefore, a new solution needs to be designed to improve it. Summary of the invention

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a non-standard attachment connection structure for a construction hoist, including: a reinforced concrete wall 1 and a connection structure. The connection structure includes a pre-embedded backing plate 2, two groups of pre-embedded parts 6 and four groups of screw pipes 9, a support 13 and an attachment rod 4. The pre-embedded parts 6 are precast in the reinforced concrete wall 1, and the pre-embedded parts 6 include two pre-embedded nuts 14 and arc-shaped steel plates 19. The two arc-shaped steel plates 19 are symmetrically distributed and their two ends are respectively welded to the pre-embedded nuts 14 to form a fish-shaped structure. An installation hole 7 communicating with the through hole of the pre-embedded nut 14 is provided on the surface of the reinforced concrete wall 1. By connecting the pre-embedded parts 6 with the pre-embedded steel bars 21 in the reinforced concrete wall 1, it has good connection strength, and the connection strength between the steel bars can also be improved when welded to the pre-embedded steel bars 21; the pre-embedded backing plate 2 is placed on the surface of the reinforced concrete wall 1 and several pre-embedded bolts 8 are welded on the surface of the pre-embedded backing plate 2. The pre-embedded backing plate 2 plays a role in protecting the wall surface and can also increase the stability of the installation of the support 13. Every four pre-embedded bolts 8 are in a group and are distributed in a 2X2 matrix. The support 13 is fixed by the pre-embedded bolts 8, which can play an anti-offset effect from multiple angles. The pre-embedded bolts 8 are perpendicularly connected to the surface of the pre-embedded backing plate 2 and the ends of the pre-embedded bolts 8 are buried in the reinforced concrete wall 1. Four side holes 25 are provided near the corners on the surface of the support 13, and a middle hole 24 is provided in the middle. A hole corresponding to the middle hole 24 is provided on the surface of the pre-embedded backing plate 2. The end of the screw pipe 9 passes through the middle hole 24 and extends into the installation hole 7 and is threadedly connected to the pre-embedded nut 14. A limit ring 18 is provided at the other end of the screw pipe 9. The connection surface of the limit ring 18 and the screw pipe 9 fits on the surface of the support 13. The installation of the screw pipe 9 is simple and convenient for later disassembly. After the screw pipe 9 is installed, the limit ring 18 can also play a role in fixing and limiting the support 13. Threaded structures 10 are provided on the left end surface of the attachment rod 4 and on the inner wall of the screw pipe 9. One end of the attachment rod 4 with threads passes through the limit ring 18 and is threadedly connected to the screw pipe 9. The end of the attachment rod 4 extends into the installation hole 7. The installation of the attachment rod 4 is simple and convenient for later disassembly. A reinforcing member 11 is connected between the attachment rod 4 and the support 13. The reinforcing member 11 increases the installation strength and stability of the attachment rod 4. A reinforcing rod 5 is connected between the attachment rods 4. The reinforcing rod 5 increases the connection stability between the attachment rods 4.

There are four connecting plates 15 in total, which are welded to one end of the sleeve 16. The four connecting plates 15 are arranged obliquely and distributed annularly around the center of the sleeve 16. The fixing plate 12 is welded to the other end of the connecting plate 15, and the surface of the fixing plate 12 is in the same plane as the surface of the support 13. Through holes are provided on the surface of the fixing plate 12 and are connected to the embedded bolts 8 through the through holes and fastened with nuts. The attachment rod 4 is connected to the embedded bolts 8 and the support 13 through the reinforcement member 11.

[0025] Further improved, as Figure 2 shown in the figure: The sleeve 16 is sleeved on the attachment rod 4 and is movably connected to the attachment rod 4. A limit block 17 is fixed on the attachment rod 4 to limit the position of the sleeve 16. After the attachment rod 4 and the reinforcement member 11 are installed, the side wall of the limit block 17 just fits the sleeve 16.

[0026] Further improved, as Figure 4 shown in the figure: The fixing plate 12 is in a quarter-circular structure. Grooves 23 for fittingly connecting with the positioning plate are provided on the surface of the support 13 and at the side holes 25.

When installing the connection structure, the back of the support 13 is attached to the embedded bearing plate 2, the side holes 25 are connected to the embedded bolts 22, the screw tube 9 is passed through the middle hole 24 and placed in the installation hole 7. After the screw tube 9 is connected and fastened with the nut 14, the limiting ring 18 plays a certain limiting role on the support 13. Then, the attachment rods 4 are respectively screwed into the screw tube 9, and the ends extend outside the screw tube 9. The sleeve 16 of the reinforcing member 11 is sleeved on the attachment rod 4. Then, the fixing plate 12 is attached to the groove 23 on the surface of the support 13 and connected to the embedded bolt 8. Then, the nut 14 is used to fasten the embedded bolt 8. Then, the reinforcing rods 5 are installed. After the installation is completed, the two reinforcing rods 5 are fixed to complete the installation.
