Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a connection structure of adjacent components of a prefabricated external elevator shaft. Background Art

[0002] With the development of the construction industry, prefabricated buildings are gaining widespread adoption due to their high efficiency and environmentally friendly advantages. In the construction of prefabricated external elevator shafts, the connection structure of adjacent components is crucial for ensuring the overall stability and safety of the elevator shaft. However, existing connection structures have some shortcomings, such as insufficient connection strength and complex installation.

[0003] Patent application number CN201921765971.X discloses a connector for adjacent components of a spatial steel structure. Positioning blocks a are welded to the front and rear sides of the left connecting pipe. The right side of the left connecting pipe is connected to the right connecting pipe via a fixing member. Positioning blocks b, flush with positioning blocks a, are welded to the front and rear sides of the left connecting pipe. The fixing member includes a mounting plate and bolts a. Bolts a pass through the mounting plate and connect to positioning blocks b and positioning blocks a respectively. Fixing blocks a are welded to the upper and lower sides of the left connecting pipe, and fixing blocks b are welded to the upper and lower sides of the right connecting pipe. An upper connecting pipe is mounted above the upper right fixing block a and above the upper left fixing block b via bolts b. The spacing between the left and right fixing blocks a is equal to the width of the upper connecting pipe. Fixing blocks c are welded to the left and right sides of the lower part of the upper connecting pipe. The connector can be disassembled and used according to the connection direction of the components, which is highly flexible. At the same time, the provision of drain holes facilitates the rapid discharge of water inside the connector.

[0004] However, the connectors in the aforementioned patented technology are not suitable for use in assembled external elevator shafts, and the shear resistance of the connectors does not meet the requirements of assembled external elevator shafts. Therefore, a new type of connection structure is needed to solve these problems. Summary of the Invention

[0005] The object of the present invention is to provide a connection structure for adjacent components of an assembled external elevator shaft to solve the problems raised in the above background technology:

[0006] (1) How to improve the connection strength and installation efficiency between components.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A connection structure for adjacent components of an assembled external elevator shaft, wherein the adjacent components are a first component and a second component, and a cavity is provided inside the first component and the second component respectively;

[0009] The first component and the second component are respectively provided with a plurality of first component connection through holes at corresponding positions, and the first component and the second component are also provided with first component shear resistance through holes at corresponding positions, and a component connection component and a component shear resistance component are provided between the first component and the second component;

[0010] The component connection assembly includes a plurality of first component connection bolts and a plurality of first component connection nuts, wherein the plurality of first component connection bolts and the plurality of first component connection nuts are in a one-to-one correspondence with the plurality of first component connection through holes of the cover plate, and the plurality of first component connection nuts are fixedly connected to the inner wall of the first component cavity, and the first component connection bolts sequentially penetrate the first component connection through holes of adjacent first and second components from the second component cavity and cooperate with the corresponding first component connection nuts;

[0011] The component shear assembly includes a component shear sleeve, a component shear sealing plate, a component shear bolt and a component shear nut. The component shear sealing plate is fixedly connected to the inner wall of the first component cavity. The component shear sealing plate covers the first component shear through-hole of the first component cavity. The component shear sealing plate is provided with a second component shear through-hole communicating with the first component shear through-hole. The component shear nut is fixedly connected to the component shear sealing plate on the side of the first component shear through-hole away from the first component cavity. The component shear sleeve passes through the first component shear through-holes of the first component and the second component in sequence from the second component cavity and abuts against the component shear sealing plate. The component shear bolt passes through the inner hole of the component shear sleeve and the second component shear through-hole of the component shear sealing plate in sequence from the second component cavity and cooperates with the component shear nut.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, the outer wall of the end portion of the component shear sleeve in the second component cavity extends outward to form a limiting ring portion, and the head of the shear bolt abuts against the end surface of the limiting ring portion of the component shear sleeve.

[0014] Furthermore, a second operating window communicating with the cavity is formed on the side wall of the second component.

[0015] Furthermore, the first component shear through hole and the plurality of first component connecting through holes of the first component are located on the end surface of the first component, and the first component shear through hole and the plurality of first component connecting through holes of the second component are also located on the end surface of the second component.

[0016] Furthermore, the first component shear-resistant through hole and the plurality of first component connecting through holes of the first component are located on the side wall of the first component, and the first component shear-resistant through hole and the plurality of first component connecting through holes of the second component are located on the end surface of the second component.

[0017] Furthermore, the component anti-shear sealing plate covers all the first component connecting through holes in the first component cavity, and the component anti-shear sealing plate has a plurality of second component connecting through holes at positions corresponding to the plurality of first component connecting through holes of the first component.

[0018] With this structure, the first component is arranged vertically and the second component is arranged horizontally, each with a cavity inside. This layout allows the components to fit together spatially, providing a foundation for subsequent connection.

[0019] Four first-member connecting holes and one first-member shear hole are respectively defined at corresponding locations on the first and second members. The first-member connecting holes and shear holes are located on the sidewalls, while the second-member connecting holes and shear holes are located on the end faces. This arrangement of holes provides access for connecting bolts and shear sleeves, ensuring a viable connection.

[0020] The connection mode of the component connection assembly is adopted to achieve a firm connection between the first component and the second component through the cooperation of bolts and nuts.

[0021] The design of this shear assembly enhances the shear resistance between components through the mutual cooperation of shear sleeves, sealing plates, bolts and nuts.

[0022] A retaining ring extends outward from the outer wall of the end of the component shear sleeve within the cavity of the second component. The head of the shear bolt abuts against the end face of the retaining ring of the component shear sleeve. The distance from the retaining ring to the other end face of the component shear sleeve is equal to the sum of the first component shear holes of the first and second components. This retaining ring design limits the position of the shear sleeve, ensuring the stability and reliability of the shear assembly.

[0023] The second operating window on the side wall of the second component facilitates operation and installation.

[0024] In addition, due to the size of the shear sleeve, smaller connecting bolts can be selected as long as the tension requirements between the two components are met.

[0025] The beneficial technical effects of the connection structure of adjacent components of the assembled external elevator shaft are:

[0026] (1) Improve the connection strength and stability. Through the combined action of the component connection assembly and the component shear assembly, the connection between the first component and the second component is made more secure. The coordination of the connecting bolts and nuts, as well as the coordination of the shear sleeve, the sealing plate, the bolts and the nuts, can effectively enhance the connection strength between the components. At the same time, the design of the shear assembly also improves the shear resistance between the components, thereby ensuring the overall stability and safety of the assembled external elevator shaft.

[0027] (2) Improve installation efficiency. This connection structure is reasonably designed and easy to install. The installation process of the component connection assembly and the component shear assembly is simple. You only need to follow the corresponding steps to match the bolts and nuts and penetrate the shear sleeve. This convenient installation method can effectively improve construction efficiency and shorten the construction period.

[0028] (3) To ensure construction quality, the first and second components are each provided with a cavity, and a connection hole and a shear hole are respectively opened at the corresponding position. This design enables the connection component and the shear component to be accurately installed in the predetermined position. At the same time, the welding fixation of each component and the matching of bolts and nuts can also ensure the accuracy and quality of the connection. In addition, the second operation window on the side wall of the second component facilitates operation and installation, further ensuring construction quality.

[0029] (4) Reduce construction costs. Since the installation process of the connection structure is simple and does not require complex construction equipment and a large amount of labor, it can reduce construction costs. At the same time, its reasonable structural design also reduces material waste, further reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS
