Description

Technical Field

[0001] This utility model relates to the field of subway station construction technology, and in particular to a wall-mounting system suitable for fully prefabricated assembled stations. Background Technology

[0002] Currently, in the production process of fully prefabricated subway stations, the central slab and the suspended wall are prefabricated separately as individual components. After the components arrive at the construction site, they need to be assembled. However, since the suspended wall components need to be installed on the bottom surface of the central slab, and the traditional installation of the suspended wall is generally to assemble it in the foundation pit after the central slab is installed to the assembly point, this construction method has the following risks and shortcomings: 1. After the central slab is installed to the assembly position, it is impossible to use highly mechanized equipment for assembly, resulting in high construction difficulty; 2. The installation of the suspended wall in the foundation pit requires a lot of installation time and labor, resulting in high construction costs; 3. The installation of the suspended wall requires manual labor in conjunction with a hand-operated hoist for lifting and installation, which poses high safety risks.

[0003] Among the aforementioned technical issues: Technical Issue 1: Directly affects construction efficiency and feasibility, as the installation of large components in the foundation pit requires a large number of auxiliary tools and equipment if done entirely manually; Technical Issue 2: Directly affects construction costs, as the large amount of manpower not only increases labor costs but also slows down the assembly speed, affecting the construction period and costs; Technical Issue 3: Requires specialized working tools, and the hoisting height is relatively large, which poses a risk of injury to workers on the platform level.

[0004] For example, patent CN118309105A discloses a construction method for prefabricated platform screen wall of a prefabricated station. The completed prefabricated platform screen wall is hoisted into a prefabricated fixture by a gantry crane and then transported to the installation location. The two sides of the fixture are fixedly connected to the Huffen hooks by a hand chain hoist. The installation by hand chain hoist is cumbersome and has high safety risks. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wall-mounted installation system suitable for fully prefabricated assembled stations, aiming to achieve efficient installation, low safety risks, and low construction costs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A wall-mounted installation system suitable for fully prefabricated assembled stations includes a middle plate fixed frame, a wall-mounted movable frame, and stairs for going up and down;

[0008] The middle plate fixing jig is used to support the end of the hoisted middle plate. The middle plate fixing jig consists of a pair of fixing jig structures arranged opposite each other.

[0009] The wall-mounted movable frame is used to support the wall-mounted device and move it to the installation position. The wall-mounted movable frame includes a base frame and a pair of support vertical frames mounted on the base frame. There is a gap between the pair of support vertical frames, and a movable adjustment structure is provided under the base frame.

[0010] The stairs are used by workers to connect the top surface of the middle plate.

[0011] Further or preferred:

[0012] The middle plate fixing frame is a frame support structure, and a pad plate is provided on the top of the frame support structure.

[0013] The frame support structure includes a set of middle plate support columns, with the tops of adjacent middle plate support columns connected by middle plate support crossbeams, and scissor bracing provided between adjacent middle plate support columns.

[0014] The base frame is provided with a bottom support frame for supporting the bottom of the suspended wall between a pair of load-bearing vertical frames.

[0015] The bottom support frame includes a wall-mounted bottom support longitudinal beam and a set of wall-mounted bottom support uprights. The set of wall-mounted bottom support uprights are fixed in parallel along the longitudinal direction in the middle of the base frame, and the wall-mounted bottom support longitudinal beam is fixed on the top of the set of wall-mounted bottom support uprights.

[0016] Each of the aforementioned support frames includes a support longitudinal beam and a set of support uprights. The set of support uprights is vertically fixed to the base frame, and the support longitudinal beam fixes the top of the set of support uprights. The support longitudinal beam is provided with padding strips.

[0017] The supporting longitudinal beam is equipped with a movable positioning structure for positioning the end of the suspended wall.

[0018] The movable adjustment structure includes a vertical adjustment structure, a horizontal adjustment structure, and a longitudinal adjustment structure.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] This wall-mounting system, applicable to fully prefabricated assembled stations, is rationally designed. It utilizes a fixed jig to raise and fix the middle plate, and a mobile jig to move the wall-mounting device into the installation position. After installing the upper and lower passages, workers enter the top surface of the middle plate and use the extension cylinders of the mobile jig to lift the wall-mounting device to the installation position. Position adjustment is performed using a combination of horizontal cylinders, and manual connection is carried out after alignment. The system boasts a high level of mechanization, improving installation efficiency and reducing installation risks. It also reduces the number of workers required during assembly, thus lowering installation costs. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0032] like Figures 1 to 7 As shown, the wall-mounting installation system applicable to fully prefabricated assembled stations includes a fixed frame 21 for the middle plate, a movable frame 22 for the wall-mounting, and stairs for accessing the upper and lower sections. It mainly solves the problem of difficult installation of the middle plate 19 and the wall-mounting 1. The fixed frame is used to raise and fix the middle plate, and the movable frame is used to send the wall-mounting to the installation point. After the upper and lower passages are installed, the workers enter the top surface of the middle plate and use the extension cylinder of the movable frame to lift the wall-mounting to the installation point. The position is adjusted by the combination of horizontal cylinders, and the connection is made manually after the point is aligned.

[0033] The middle plate fixing jig is used to support the ends of the hoisted middle plate. It consists of a pair of opposing fixing jig structures, which support and position both ends of the middle plate. The wall-mounting movable jig is used to move the wall-mounting device to the installation position. This jig includes a base frame and a pair of supporting vertical frames mounted on the base frame, with a gap between them. A movable adjustment structure is located below the base frame. The wall-mounting device has a T-shaped cross-section, supported by the pair of supporting vertical frames. The stairs are used by workers to connect the top surface of the middle plate. The stairs are movable access channels 20, providing access for workers to move the middle plate up and down. The entire system can meet the needs of assembling the middle plate and wall-mounting device on the ground, enabling mechanized and rapid installation of the wall-mounting device.

[0034] The middle plate fixing frame is a frame support structure, i.e., a steel truss structure; and a pad plate is provided on the top of the frame support structure to prevent friction damage to the middle plate. Preferably, the frame support structure includes a set of middle plate support uprights 17, the tops of adjacent middle plate support uprights are connected by middle plate support crossbeams 16, and scissor braces 18 are provided between adjacent middle plate support uprights, making the structure stable and reliable.

[0035] A bottom support frame for supporting the bottom of the suspended wall is provided on the base frame between a pair of supporting vertical frames. The base frame includes a bottom horizontal beam 7 and a bottom longitudinal beam 9, which are welded together to form a square base frame structure. Preferably, the bottom support frame includes a wall-mounted bottom support longitudinal beam 5 and a set of wall-mounted bottom support uprights 6. The set of wall-mounted bottom support uprights is fixed longitudinally in the middle of the base frame, and the wall-mounted bottom support longitudinal beam is fixed on the top of the set of wall-mounted bottom support uprights. By supporting the bottom of the suspended wall with the bottom support frame, the top two sides of the suspended wall and the bottom are supported together, ensuring stable and reliable positioning.

[0036] Furthermore, the supporting longitudinal beam is provided with a movable positioning structure for positioning the end of the suspended wall; preferably, the movable positioning structure is a positioning pin, and the supporting longitudinal beam is provided with a positioning hole, which is fixed by the threaded structure at the lower end of the positioning pin, thereby further positioning the position of the suspended wall.

[0037] The supporting vertical frames on both sides have the same structure and are symmetrically arranged. Each supporting vertical frame includes a supporting longitudinal beam 2 and a set of supporting uprights 3. The set of supporting uprights is vertically fixed on the base frame. Supporting diagonal braces 4 are provided between adjacent supporting uprights for reinforcement. The supporting longitudinal beam fixes the top of the set of supporting uprights. Padding strips are provided on the supporting longitudinal beam to prevent friction damage to the hanging wall.

[0038] The movable adjustment structure includes a vertical adjustment structure 9, a horizontal adjustment structure 10, and a longitudinal adjustment structure 12, enabling movement and adjustment in all directions. Preferably, the movable wall-mounted frame includes a moving system, a top extension structure, a support system, and a hydraulic control system. The moving system functions as a whole movable frame, enabling horizontal and longitudinal movement, and is composed of a combination of horizontal cylinder groups, longitudinal cylinders, temporary supports 14, and connecting steel sections 13. The top extension system enables the wall to be raised and lowered, and is composed of a combination of vertical cylinder groups. The support system provides support during the movement of the wall.

[0039] The combination of the lateral adjustment structure and the longitudinal adjustment structure forms a moving system; it includes a lateral cylinder and a longitudinal cylinder set on the pad 11. The lateral cylinder and the longitudinal cylinder are combined for adjustment, and their models are determined according to the lateral and longitudinal displacement stroke requirements. The lateral adjustment satisfies the lateral micro-adjustment function of the wall-mounted device, and the longitudinal adjustment satisfies the longitudinal movement of the mobile frame.

[0040] The support piers of the mobile system must have the strength and rigidity to meet the requirements of the upper frame and temporary support for the suspended wall; the connecting steel profiles must be adjusted according to the thrust of the hydraulic cylinders; the hydraulic control system 15 must be capable of simultaneously controlling the stroke of the horizontal, vertical, and transverse hydraulic cylinder adjustment devices; the support system, i.e., the support structure, must have its strength and rigidity adjusted according to the weight of the suspended wall and the system itself. Alternatively, a shuttle car with lifting and adjustment functions can be used for the mobile adjustment structure.

[0041] This utility model utilizes a wall-mounting system suitable for fully prefabricated assembled railway stations to implement a construction method for wall-mounting installation, including the following steps:

[0042] S1. After the precast middle plate fixing frame is installed, the middle plate is hoisted and installed onto the two middle plate fixing supports.

[0043] S2. Assemble the wall-mounted mobile frame, hoist the wall into place on the wall-mounted mobile frame, start the hydraulic control system, and use the lateral and longitudinal adjustment structures to move the frame horizontally.

[0044] S3. When the two wall-mounted movable jigs are moved to the assembly point at the bottom of the middle plate, they are manually aligned. The movable jigs are then fine-tuned using the horizontal and vertical adjustment structures to adjust the position of the wall-mounted jigs.

[0045] S4. Workers enter the top surface of the middle plate through the upper and lower passages, activate the vertical adjustment structure to make the top surface of the hanging wall contact the bottom surface of the middle plate, and make bolt connections.

[0046] S5. Repeat the above operation process to proceed to the next stage of assembling the middle plate and hanging wall.

[0047] This invention utilizes a fixed jig to raise and fix the middle plate, and a movable wall-mounted jig to send the wall into the installation position. After the upper and lower passages are installed, workers enter the top surface of the middle plate and use the extension cylinder of the movable wall-mounted jig to raise the wall to the installation position. The position is adjusted by a combination of horizontal cylinders, and manual connection is performed after the position is aligned. The invention features a high level of mechanization, which improves installation efficiency and reduces installation risks. It also reduces the number of workers required during the assembly process, which helps to reduce installation costs.

[0048] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.

[0049] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
