Description

Technical Field

[0001] This utility model belongs to the field of membrane structure construction technology, and in particular relates to a rapid installation device for wind-resistant cables in membrane structures. Background Technology

[0002] With the development of construction technology, tubular truss frame membrane structures have been widely used in the construction field due to their light weight and high styling flexibility. However, traditional wind-resistant cable installation methods have some problems, such as high mechanical and labor costs and low installation efficiency. Specifically, construction usually requires the steel structure to be installed first, followed by the wind-resistant cables, and finally the membrane fabric. When installing the wind-resistant cables, three cranes need to work in precise coordination to simultaneously lift the middle and both ends of the cables and then install them into the designated positions on the steel structure. This installation method not only increases mechanical and labor costs but also, due to the high operational difficulty, limits the installation to only two wind-resistant cables per day, severely impacting the membrane fabric installation time and the overall project progress.

[0020] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0021] This utility model proposes a rapid installation device for wind-resistant cables in membrane structures to address the problems of low installation efficiency and high construction costs associated with existing wind-resistant cable installation methods. The membrane structure is supported by a supporting structure, and the wind-resistant cables are installed on the outside of the membrane structure, forming a self-balancing force system together with the membrane structure and supporting structure to ensure the stability of the structure under external forces such as wind loads. In the prior art, to avoid damage to the membrane structure during wind-resistant cable installation, the wind-resistant cables are usually installed first, followed by the membrane structure installation using specialized tools. However, due to the long length and large number of wind-resistant cables, at least three cranes are typically required for precise installation, resulting in high operational difficulty and low construction efficiency, leading to increased costs and project delays. Therefore, this application proposes a new wind-resistant cable installation device and method that enables the early installation of the membrane structure without causing damage, while ensuring installation accuracy, improving installation efficiency, and reducing installation costs.

[0022] like Figure 1 As shown, this embodiment proposes a rapid installation device for wind-resistant cables of a membrane structure, including a fixing mechanism 1, a traction mechanism 6, and multiple tensioning trolleys 3; the fixing mechanism 1 and the traction mechanism 6 are arranged opposite each other on both sides of the transverse span of the membrane fabric 5; the fixing mechanism 1 is wound with wind-resistant cables 2, and the unfolded section of the wind-resistant cables 2 extends along the membrane fabric 5 towards the traction mechanism 6; the traction mechanism 6 includes a traction rope 61, which is connected to the unfolded section; the tensioning trolleys 3 are connected to the unfolded section in sequence at a set interval and are tumblingly connected to the membrane fabric 5.

[0023] It should be noted that in this embodiment, both the support structure and the membrane structure have been installed in advance. The support structure adopts a tubular truss 4 structure, and the membrane structure includes a membrane fabric 5, which covers the tubular truss 4 and has a longitudinal span along the length of the overall structure and a transverse span along the width. Multiple wind-resistant cables 2 are installed on the membrane fabric 5 along the transverse span according to the designed spacing.

[0024] In use, the traction mechanism 6 drives the wind-resistant cable 2 and the tensioning trolley 3 to move along the transverse span of the membrane fabric 5, which can precisely define the position and direction of movement of the wind-resistant cable 2, so that the wind-resistant cable 2 is installed in the set position. Through the cooperation of the fixing mechanism 1, the traction mechanism 6 and the tensioning trolley 3, this application can accurately and efficiently place the wind-resistant cable 2 in the set position, so that its two ends can be fixed to the truss 4 with special anchors in subsequent operations. Compared with the prior art, which uses three cranes to lift the middle and two ends of the wind-resistant cable 2 into place respectively, this method is more efficient. This method reduces operational difficulty, is faster and more convenient, and improves installation accuracy and efficiency. The fixing mechanism 1, traction mechanism 6, and tensioning trolley 3 all use commonly used equipment on the construction site or are self-made, which significantly reduces mechanical costs compared to the use of cranes. At the same time, since the tensioning trolley 3 separates the wind-resistant cable 2 from the membrane fabric 5, it avoids contact between the wind-resistant cable 2 and the membrane fabric 5, so that the membrane fabric 5 will not be damaged during positioning and installation. This provides conditions for the prior construction of the membrane fabric, optimizes the installation process of the wind-resistant cable 2, and is conducive to saving the overall construction period.

[0025] In the embodiments of this application, such as Figure 2 As shown, the fixing mechanism 1 includes a rotatable winch 11, and the wind-resistant cable 2 is wound around the winch 11. The fixing mechanism 1 is used to fix the wind-resistant cable 2 to one side of the support structure that is adapted to its intended installation position. By rotating the winch 11, in cooperation with the traction mechanism 6 and the tensioning trolley 3, the wind-resistant cable 2 wound on the winch 11 can be continuously extended and stretched until the wind-resistant cable 2 moves to the set position.

[0026] Specifically, the aforementioned fixing mechanism 1 further includes a bracket, a winch 11 is mounted on the bracket, and includes a vertically arranged rotating shaft, with the wind-resistant cable 2 wound around the rotating shaft. When the rotating shaft rotates axially relative to the bracket, the wind-resistant cable 2 can extend. In an embodiment, the extended end of the wind-resistant cable 2 is connected to a traction mechanism 6, and under the traction force of the traction mechanism 6, it continuously extends, thereby driving the rotating shaft to rotate. In other embodiments of this application, the winch 11 is connected to a driving device for driving the rotating shaft to rotate, which, in conjunction with the traction mechanism 6, allows the wind-resistant cable 2 to extend more smoothly. The bracket can be fixed on the ground or on other equipment. To facilitate the movement of the fixing mechanism 1 and adapt to the installation of the wind-resistant cable 2 at different positions in the longitudinal span direction of the overall structure, preferably, the bracket is fixed on a vehicle.

[0027] Furthermore, in this embodiment, the centers of the traction rope 61, the wind-resistant cable 2, and the tensioning trolley 3 are aligned. By setting the centerlines of the three to be collinear, it can be ensured that the traction force of the traction mechanism 6 is transmitted in a straight line. As long as the initial positions of the traction rope 61, the tensioning trolley 3, and the wind-resistant cable 2 are accurate, the tensioning trolley 3 and the wind-resistant cable 2 can travel along the set line, thereby ensuring that the wind-resistant cable 2 is accurately positioned and in place in one go. There is no need to adjust the position of the tensioning trolley 3 during the process, which reduces the difficulty of operation and improves the installation efficiency while ensuring positioning accuracy.

[0028] In this embodiment, the tensioning trolley 3 is provided with at least four directional wheels 31 to ensure that the tensioning trolley 3 moves along a straight line and does not deviate to the sides, thereby ensuring the installation accuracy of the wind-resistant cable 2.

[0029] Furthermore, such as Figure 3 As shown in this embodiment, the end of the unfolded section is provided with a cable head 21, which is fixed to the tensioning trolley 3 and connected to the traction rope 61. It can be understood that the cable head 21 is the end portion of the wind-resistant cable 2. As the unfolded section continues to extend, the number of tensioning trolleys 3 connected to the wind-resistant cable 2 increases, with the cable head 21 fixed to the foremost tensioning trolley 3. Simultaneously, the cable head 21 is connected to the traction rope 61, forming a force-bearing system of traction rope 61-wind-resistant cable 2-tensioning trolley 3. The force transmission path is reasonable, improving the integrity and stability of the traction rope 61, wind-resistant cable 2, and tensioning trolley 3, ensuring synchronous movement of the three.

[0030] In a specific technical solution of the above embodiment, the cable head 21 is provided with a connecting hole, and the traction rope 61 is passed through the connecting hole. Through this connection method, it can be ensured that the center of the traction rope 61 passes through the center of the cable head 21, so that the traction rope 61 is on the extension line of the wind-resistant cable 2. As long as the pulling direction of the traction rope 61 is correct, the traction force can be ensured to be transmitted in a straight line, which improves the accuracy of the movement and positioning of the wind-resistant cable 2.

[0031] Furthermore, such as Figure 3As shown in this embodiment, the tensioning trolley 3 includes a frame, a support plate 32 on the top of the frame, and a limiting buckle 33 at the center of the top of the support plate 32. The limiting buckle 33 is adapted to the shape of the wind-resistant cable 2 and can fix the wind-resistant cable 2 to the support plate 32. The support plate 32 is used to support the wind-resistant cable 2, and the limiting buckle 33 can fix the wind-resistant cable 2 to the center of the support plate 32. The wheels are set at the bottom of the support plate 32, which on the one hand reduces the friction between the tensioning trolley 3 and the membrane fabric 5, so that the tensioning trolley 3 can move smoothly, and on the other hand, the support plate 32 separates the wind-resistant cable 2 from the membrane fabric 5 to prevent the wind-resistant cable 2 from contacting and rubbing against the membrane fabric 5 during movement. Preferably, the limiting buckle 33 can form a stable limit on the wind-resistant cable 2, which can prevent the wind-resistant cable 2 from sliding relative to the tensioning trolley 3 along the moving direction of the tensioning trolley 3, and also prevent it from shifting to the sides.

[0032] In one specific technical solution described above, the limiting buckle 33 is an arched ring shape. The two ends of the opening of the limiting buckle 33 are detachably fixed to the support plate 32, and the wind-resistant cable 2 passes through the limiting buckle 33. The two ends of the opening of the limiting buckle 33 are provided with connecting ears, which can be fixed to the support plate 32 by fasteners. The shape of the limiting buckle 33 is slightly smaller than the diameter of the wind-resistant cable 2, which can lock the wind-resistant cable 2, fixing it between the limiting buckle 33 and the support plate 32. The detachable connection method is convenient to operate and ensures the tightness of the locking of the limiting buckle 33 to the wind-resistant cable 2.

[0033] Understandably, each tensioning trolley 3 is equipped with a limit buckle 33. The number of limit buckles 33 can be one or more. When there is only one limit buckle 33, it can be set at one end of the support plate 32 near the fixing mechanism 1. When there are multiple limit buckles 33, they can be evenly arranged along the length of the wind-resistant cable 2. Normally, the shape of the cable head 21 of the wind-resistant cable 2 is larger than its main body shape. That is to say, the shape of the cable head 21 is larger than the limit buckle 33, so that the tensioning trolley 3 at the front end can not only lock the wind-resistant cable 2 through the limit buckle 33, but also lock the cable head 21, so that the wind-resistant cable 2 is stably fixed on the tensioning trolley 3 to ensure the safety of the operation process.

[0034] Furthermore, the aforementioned support plate 32 is equipped with an anti-slip pad. By setting the anti-slip pad, the friction between the wind-resistant cable 2 and the support plate 32 is increased, further improving the stability of the wind-resistant cable 2 and ensuring operational safety. Preferably, the wind-resistant cable 2 can also be tied to the support plate 32 with a rope.

[0035] In this embodiment, the membrane fabric 5 and the supporting structure are arched along the transverse span. The distance between adjacent tensioning trolleys 3 and the number of tensioning trolleys 3 are set according to the length of the wind-resistant cable 2 and the shape of the membrane fabric 5. As long as the wind-resistant cable 2 between adjacent tensioning trolleys 3 does not come into contact with the membrane fabric 5 when the tensioning trolley 3 moves along the transverse span of the membrane fabric 5.

[0036] like Figure 4 As shown in the figure, this application also proposes a method for rapid installation of wind-resistant cables for membrane structures, which uses the above-mentioned rapid installation device for wind-resistant cables for membrane structures and includes the following steps:

[0037] S1. The installation of the steel structure and membrane fabric 5 was completed successively;

[0038] In this embodiment, the steel structure is a tubular truss structure.

[0039] S2. According to the proposed installation position of the wind-resistant cable 2, the fixing mechanism 1 and the traction mechanism 6 are respectively set on both sides of the transverse span of the membrane 5.

[0040] Specifically, the fixing mechanism 1 and the traction mechanism 6 are respectively aligned with the intended installation position of a wind-resistant cable 2, so that the center line of the traction rope 61 and the unfolded section of the wind-resistant cable 2 are aligned with the center line of the intended installation position of the wind-resistant cable 2.

[0041] S3. Fix the cable head 21 of the unfolded section of the wind-resistant cable 2 to the first tensioning trolley 3, and connect the cable head 21 to the traction rope 61 of the traction mechanism 6.

[0042] Specifically, the unfolded section is locked by the limit buckle 33, so that the cable head 21 faces the traction mechanism 6; then the traction rope 61 is passed through the connection hole of the cable head 21 and securely connected.

[0043] S4. The traction mechanism 6 is running. The wind-resistant cable 2 is continuously extended under the drive of the traction rope 61, and drives the first tensioning trolley 3 to move along the membrane 5 towards the traction mechanism 6.

[0044] S5. After the unfolding section has been extended to the set length, connect another tensioning trolley 3 to the unfolding section;

[0045] Similarly, the wind-resistant cable 2 is locked by the limit buckle 33, so that the unfolding section is stably connected to the tensioning trolley 3.

[0046] S6. The traction mechanism 6 and the tensioning trolley 3 are interleaved. When both ends of the wind-resistant cable 2 are in the set position, the traction rope 61 and the tensioning trolley 3 are released, and the wind-resistant cable 2 is connected to the anchor at the set position.

[0047] As the length of the unfolded section increases, once the set distance is increased, the traction mechanism 6 stops operating, and the next tensioning trolley 3 is connected to the unfolded section until the entire length of the wind-resistant cable 2, along with the tensioning trolley 3, reaches the intended installation position of the wind-resistant cable 2. That is, when both ends of the wind-resistant cable 2 are in the set position, the traction rope 61 and the tensioning trolley 3 are untied, and the wind-resistant cable 2 is connected to the anchor at the set position, thus completing the installation of the wind-resistant cable 2.

[0048] When the tensioning trolley 3 needs to be removed, the limit buckle 33 can be opened to disconnect the tensioning trolley 3 from the wind-resistant cable 2, which is convenient to operate. After the tensioning trolley 3 is removed, the positions of the two ends of the wind-resistant cable 2 will shift outwards, which will not affect the connection between the wind-resistant cable 2 and the anchor.

[0049] The advantages and positive effects of this utility model are as follows: By cooperating with the fixing mechanism, the traction mechanism and the tensioning trolley, the wind-resistant cable can be accurately and efficiently placed in the set position. Compared with the prior art which uses three cranes to cooperate in the operation, the operation difficulty is reduced, and it is faster and more convenient, improving the installation accuracy and efficiency. It significantly reduces mechanical costs, avoids contact between the wind-resistant cable and the membrane fabric, provides conditions for the prior construction of the membrane fabric, optimizes the installation process of the wind-resistant cable, and is conducive to saving the overall construction period.

[0050] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
