Description

Technical Field

[0001] This application pertains to the field of steel structure reinforcement, and particularly relates to a single-layer mesh cover structure reinforcement component transportation device and reinforcement construction method. Background Technology

[0002] With the development of the construction industry, the design of building shapes is becoming increasingly diverse, and the demand for building shapes is also increasing. Beautiful building shapes can enhance the city's image and serve as landmark buildings or cultural symbols. Due to its strong plasticity, light weight, and high strength, steel structures are widely used in the construction of irregular-shaped structures.

[0003] Due to the scarcity of urban land, underground space is being utilized extensively, leading to the construction of an increasing number of underground shopping malls and underground passages, such as... Figure 1 As shown, some underground spaces are equipped with circular skylights on the ground, with arched single-layer mesh structures at the skylights. This not only enhances the building's aesthetics but also improves natural lighting in the underground space. Besides underground spaces, some above-ground shopping malls also incorporate circular skylights on their rooftops to increase indoor lighting, along with mesh structures to enhance roof support.

[0004] With long-term use, extreme weather, or unexpected heavy loads such as earthquakes, building structures are prone to damage. To ensure the safe use of buildings, it is necessary to reinforce and repair the arched single-layer mesh canopy structure. Reinforcement measures can include erecting a scaffold from inside the building to inspect and replace individual components of the arched single-layer mesh canopy, which can affect the normal use of the building's interior; or using cranes to bring workers to the top of the structure from outside the single-layer mesh canopy for inspection and reinforcement. However, for severely damaged structures requiring replacement of numerous reinforcement components, or when all reinforcement components need to be replaced, multiple cranes are needed to transport and hoist the reinforcement components, resulting in high construction costs and significant requirements on the load-bearing capacity of the construction site. Furthermore, multiple workers are needed to move the reinforcement components, and workers need to be hoisted to the skylight mesh canopy area. With a large number of workers and the limited load-bearing capacity of the skylight mesh canopy structure, there are significant safety risks. Summary of the Invention

[0012] A preferred technical solution of the present invention is as follows: the second sliding blocks on the same track are located on the same arc, and multiple second sliding blocks on the same arc are connected by cables. The driving device includes two sets of winches set at both ends of each main chord. The two ends of the cable on each main chord are wound around the corresponding winch.

[0014] To achieve the above-mentioned technical objectives, the present invention provides a reinforcement construction method for a single-layer mesh cover structure. This reinforcement construction method utilizes the aforementioned single-layer mesh cover structure reinforcement component transport device to hoist the reinforcement components. The specific construction steps are as follows: S1: A sliding track is laid around the perimeter of the mesh cover structure, and the assembled truss is installed on the sliding track. The assembled truss is equipped with a transfer component. The assembled truss is pushed to the installation position by a pushing mechanism, and the fixed bases at both ends of the assembled truss are fixed to the ground by anchor rods. S2: Connect the reinforcement to the lifting rope. Each reinforcement should have at least three lifting points. Connect each lifting point to a different lifting rope and ensure that at least three lifting points are not on the same track. S3: After the reinforcement component is moved along the assembly truss to the reinforcement point by the control of the drive device, the reinforcement component is lowered to the top of the mesh cover structure by the control of the winding mechanism, and then the reinforcement component and the mesh cover structure are reinforced and installed. S4: After the reinforcement components within the coverage area of ​​the assembled truss are completed, the truss is driven to rotate 8 to 10 degrees along the sliding track using the pushing mechanism, and steps S2-S3 are repeated until the entire mesh cover structure is covered and reinforced. Finally, a reinforced mesh cover structure is constructed on top of the original single-layer mesh cover structure to form a double-layer mesh frame structure.

Then, the connecting rods and the assembled track are installed sequentially along the main chord until the assembled truss is formed; in step S2, at least three lifting points of each reinforcement are connected to different driving tracks and assembled tracks respectively.

[0016] This application includes at least one of the following beneficial effects: (1) The transfer device in the invention can set up an assembly truss above the single-layer mesh cover structure and use a drive device to drive the second sliding block to move, thereby driving the reinforcement to move along the assembly truss, so that the reinforcement can be transported to the top of the single-layer mesh cover structure; then use a push mechanism to drive the assembly truss to rotate around the sliding track, so that the assembly truss covers any position above the single-layer mesh cover structure, thereby realizing the transportation of the reinforcement; on the one hand, the device occupies less space and does not affect the normal use of the building; on the other hand, the device operates outside the single-layer mesh cover structure, without the need for large machinery to enter the site, which can reduce the impact on the structural stability of the building.

[0017] (2) The present invention rotates the main chord to a vertical position by using a lifting device and cables, and assembles the connecting members directly on the main chord. At the same time, the rotation of the assembled truss is achieved by using a transfer component. No large machinery is required for construction. In addition, when transporting and installing the reinforcement components, only the truss needs to be assembled to cover the entire area of ​​the single-layer mesh structure, which reduces the involvement of large machinery and reduces the impact of the surrounding construction environment on the reinforcement construction, making the construction method of this application more widely applicable. (3) The assembly truss of the present invention includes two lower chords and one upper chord, forming a relatively stable triangular structure. At the same time, a second sliding block is provided on the two lower chords and the connecting rods between the two lower chords, so that each reinforcement can be equipped with at least three lifting points during transportation, thereby making the lifting of the reinforcement more stable and safe.

[0020] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0021] This application aims to provide a reinforcement device and reinforcement construction method for reinforcing a single-layer mesh cover structure. The construction conditions in the background art are used as an example for detailed explanation. However, the reinforcement device and reinforcement construction method of this application are not only applicable to the construction conditions in the background art. The reinforcement device and reinforcement construction method of this application can be used to reinforce any semi-circular single-layer mesh cover structure.

[0022] This invention provides a single-layer mesh cover structure reinforcement component transportation device and construction reinforcement method. Its main core is to install multiple reinforcement components on top of the single-layer mesh cover structure, so that the single-layer mesh cover structure can form a double-layer mesh frame structure, thereby improving the stability of the structure and achieving the reinforcement of the single-layer mesh cover. In the entire construction process, a single-layer mesh cover structure reinforcement component transportation device is mainly used to transport the reinforcement components, thereby avoiding the use of multiple hoisting equipment to hoist and install the reinforcement components, and also reducing the number of construction personnel.

[0023] The reinforcement transfer device used in the embodiments is specifically as follows: Figure 1 and Figure 2 As shown, the structure includes a sliding track 1 that surrounds the bottom periphery of the mesh cover structure 7, an assembly truss 2 mounted on the sliding track 1, and a pushing mechanism 4 for rotating the assembly truss 2 around the sliding track 1. The assembly truss 2 is erected above the mesh cover structure 7, and its two ends are slidably connected to the sliding track 1 via fixed bases 5. The assembly truss 2 is supported by two sets of fixed bases 5. The sliding track 1 includes an inner track 100 and an outer track 101 arranged concentrically with the mesh cover structure 7. The cross-section of the inner track 100 and the outer track 101 can be I-beam shaped or other shapes. The fixed bases 5 are slidably connected to both the inner track 100 and the outer track 101. Specifically, two arc-shaped first sliding blocks 500 are rotatably mounted on the bottom of the fixed base 5, and the two first sliding blocks 500 are slidably engaged with the inner track 100 and the outer track 101, respectively. The pushing mechanism 4 can specifically be an existing hydraulic jacking device, with two sets. The two sets of pushing mechanisms 4 are respectively used to push the fixed bases 5 at both ends of the assembled truss 2. The two sets of pushing mechanisms 4 are installed near the two fixed bases 5, respectively, to push the two fixed bases 5 to move along the sliding track 1 in the same direction, thereby allowing the assembled truss 2 to move around the sliding track 1 and cover the entire mesh structure area. When the single pushing stroke of the pushing mechanism 4 reaches its maximum stroke, its position can be moved. Generally, the assembled truss 2 will stop after rotating about 10 degrees along the sliding track 1. The reinforcement components are then hoisted. Hoisting a single axis reinforcement component takes about one or two days, after which the pushing mechanism 4 can be moved. After the assembled truss 2 is moved into place, the fixed base 5 needs to be fixed to the ground to provide stable support for the assembled truss 2 and prevent displacement of the assembled truss 2 during hoisting. Specifically, multiple anchor rods are rotatably installed around the fixed base 5, and the free ends of the multiple anchor rods are simultaneously fixed to the ground with high-strength bolts. After all the reinforcement components 8 within the coverage area of ​​the assembled truss 2 are installed, the anchor rods can be removed from the ground, and the pushing mechanism 4 can be used to push the structural components to slide along the sliding track 1, thereby adjusting the coverage area of ​​the assembled truss 2 until the entire area outside the single-layer mesh cover is reinforced and a double-layer mesh structure is formed.

[0024] The reinforcement transfer device in the embodiment is specifically as follows: Figure 3As shown, the assembled truss 2 is an arc-shaped truss assembled from multiple members, specifically including three arc-shaped main chords and connecting members 203 connecting the three main chords. The three main chords have the same curvature. The three main chords include one upper chord 200 and two lower chords 201. The two lower chords 201 are arranged on the same arc surface, and the upper chord 200 is located above the lower chords 201. The connecting members 202 are used to connect any two adjacent main chords, and the connecting members 202 and the main chords are detachably connected. After the connecting members 202 are installed, the assembled truss 2 forms an arched truss structure. The upper chord 200 and the lower chord 201 are each evenly spaced along their length with multiple assembled balls 203. The assembled balls 203 are integrally formed with the main chords, and each assembled ball 203 has multiple insertion holes for the connecting members 202 to be inserted. The connecting member 202 can be configured as a telescopic member, including a base and an extension, with the base and extension connected by threads, thereby allowing the length of the connecting member 202 to extend or retract. When installing the assembled truss 2, first move multiple main chord members to their designated positions, then install the connecting member 202 between the main chord members. Next, rotate the extension so that both ends of the connecting member 202 are inserted into the insertion holes, thus completing the installation of the connecting member 202.

[0025] The reinforcement transfer device in the embodiment refers to Figure 3 and Figure 5 The fixed base 5 includes a first base plate 501 for connecting the lower chord 201 and a second base plate 502 for connecting the upper chord 200. Both the first base plate 501 and the second base plate 502 have arc-shaped grooves 503 on their sidewalls facing the assembled truss 2. Both ends of the upper chord 200 and the lower chord 201 are hinged to arc-shaped mounting plates 204 that match the arc-shaped grooves 503. The arc-shaped mounting plates 204 are slidably disposed within the arc-shaped grooves 503, and when each main chord moves to a specified position, the base plate corresponding to the arc-shaped mounting plate 204 can be fixedly connected by high-strength bolts.

[0026] The reinforcement transfer device in the embodiment, such as Figure 2 and Figure 3 As shown, a transfer component 3 is installed on the assembly truss 2. The transfer component 3 can drive the reinforcement component 8 to move along the assembly truss 2, thereby enabling this application to cover the entire area above the single-layer mesh cover structure 7 simply by driving the reinforcement component 8 to move along the assembly truss 2 and driving the assembly truss 2 to slide along the sliding track 1, thus transporting the reinforcement component 8 to various areas above the single-layer mesh cover structure 7 and achieving the reinforcement of the single-layer mesh cover structure 7. Figure 3 and Figure 4The transfer assembly 3 includes a drive rail 300 extending along the length of the lower chord 201 and an assembly rail 303 positioned between the two lower chords 201. Drive rails 300 are respectively located at the bottom of the two lower chords 201. The drive rails 300 and the lower chords 201 are integrally formed, and the drive rail 300 is widened at the end furthest from the lower chord 201, making it inverted T-shape. The connecting rods 202 between the assembly rail 303 and the two lower chords 201 are detachably connected. Multiple second sliding blocks 302 are slidably mounted on both the drive rail 300 and the assembly rail 303. Multiple second sliding blocks 302 located under the same track are fixedly connected by cables 304. The cables 304 connect the multiple second sliding blocks 302, and each end of the cable 304 is equipped with a drive device, which can be a winch. The two ends of the cable 304 are wound around the drums of the two winches. The winches at both ends can drive the cable 304 to move the second sliding blocks 302. Specifically, one winch at one end rewinds while the other winch releases the cable, and the cable 304 moves towards the rewinding end, thereby driving the second sliding blocks 302 to move along the assembly track 303 or the drive track 300. The drive devices at the ends of the three tracks work synchronously, thereby simultaneously driving the sliding components 302 on the three tracks to move in the same direction and at the same speed.

[0027] Reference Figure 3 and Figure 4 In this embodiment, each second sliding block 302 is equipped with a winding mechanism 6, and each winding mechanism 6 is connected to a lifting rope 305 for fixing the reinforcement 8. The winding mechanism 6 has the same structure as an electric winch and can be remotely controlled. The specific remote control method is existing technology and will not be described in detail here. By driving the winding mechanism 6, the extension or retraction of the lifting rope 305 can be controlled. When transporting the reinforcement 8 using the assembly truss 2 of this application, lifting points are set according to the shape and structure of the reinforcement 8. Each lifting rope 305 is connected to one lifting point. Generally, at least three lifting points are set on the reinforcement 8, and the three lifting points are respectively connected to the lifting ropes 305 on the two lower chords 201 and the lifting ropes 305 on the assembly track 303, thereby realizing the stable movement of the reinforcement 8.

[0028] The reinforcement transfer device in the embodiment, such as Figure 4As shown, the assembly track 303 includes several assembly units. When installing the assembly track 303, each assembly unit is installed on a corresponding connecting rod 202 via a clamping and fixing mechanism 9, and the clamping and fixing mechanism is located at the splicing part of two adjacent assembly units. The clamping and fixing mechanism 9 includes a fixing block 900 fixed on the connecting rod 202 and a clamping block 901 slidably disposed on the connecting rod 202. An adjusting rod 902 is threadedly connected between the fixing block 900 and the clamping block 901. Each assembly unit is clamped and fixed between the fixing block 900 and the clamping block 901, and the adjusting rod 902 is located at the bottom of the assembly unit. The assembly unit is clamped by the fixing block 900 and the clamping block 901, and then the distance between the clamping block 901 and the fixing block 900 can be adjusted by rotating the adjusting rod 902, thereby fixing and clamping the assembly unit.

[0029] The installation process of the above-mentioned reinforcement component transportation device is as follows: The main chord 21 is transported to the periphery of the single-layer mesh cover structure 7 and laid horizontally. Since the main chord 21 is arc-shaped, it can be arranged around the outside of the single-layer mesh cover structure 7. After the lifting device 11 and the cable 10 are installed, the arc-shaped mounting plates 204 on both sides of each main chord 21 are inserted into the arc-shaped sliding groove 503. At this time, the main chord is driven to rotate by the lifting device 11 and the cable 10, thereby driving the main chord 21 to rotate to a vertical state, thus realizing the installation of the main chord. The construction device is simple, occupies little space, and has low requirements for the surrounding construction environment. When the main chord is rotated, the arc-shaped mounting plates 204 slide along the arc-shaped sliding groove 503. After the main chord 21 is rotated to the designed position, the arc-shaped mounting plates 204 can be fixed to the first base plate 501 and the second base plate 502. After the main chord is fixed, the construction personnel can install the connecting rods 202 on the main chord. After the assembly truss 2 is installed, the assembly rail 303 is installed between the connecting members 202, and the second sliding block 302 is installed on the drive rail 300 and the assembly rail 303. After the second sliding block 302 is installed, the reinforcement member 8 can be moved.

[0030] The embodiment provides a method for reinforcing a single-layer mesh cover structure, specifically using the aforementioned reinforcement component transportation device, and includes the following construction steps: Step 1: Lay and install sliding rails 1 around the perimeter of the mesh cover structure 7. After the sliding rails 1 are laid, install the assembled truss 2. First, install the main chords by transporting and horizontally laying them around the perimeter of the mesh cover structure 7, and install the fixed bases 5 on the sliding rails 1. Then, by setting multiple cables 10 and multiple lifting devices 11, each main chord is erected above the mesh cover structure 7, and both ends are installed on the corresponding fixed bases 5. After the three main chords are installed and fixed, install the connecting members 202 and the assembled rails 303 along the main chords in sequence until the assembled truss 2 is formed. The installation of the connecting members 202 and the assembled rails 303 can be assisted by hoisting the construction personnel to the main chords for installation. One to two people are hoisted at a time for assembly to avoid too many construction personnel, which may lead to insufficient load-bearing capacity. The assembled truss 2 can also be assembled on the construction site and then installed as a whole. The process of overall installation is similar to the installation process of a single main chord. The following example uses one of the lower chord members, 201. Figure 2 and Figure 6 As shown, multiple lifting devices 11 are installed between the lower chord 201 and the ground. The lifting device 11 can be a hydraulic jack. Cables 10 are installed on the opposite side of the lower chord 201. A winch is set at the other end of the cable 10 to tension the cable 10. After the lower chord 201 is driven to rotate to a vertical position by the lifting device 11 and the cable 10, the lower chord 201 is fixed to the fixed base 5. After the assembly is completed, during installation, after the whole assembly is moved into place, the ends of the three main chords are fixedly connected to the fixed base 5 respectively.

[0031] Step 2: Connect the reinforcement component 8 to the lifting rope 305. Each reinforcement component 8 shall have at least three lifting points, and the three lifting points shall be connected to the two main chord rods 21 and the assembly track 303 respectively. Step 3: Use the drive device to move the cable 304 until the reinforcement component 8 is moved to the reinforcement point. Then, use the reeling mechanism 6 to hoist the reinforcement component 8 to the bottom of the assembled truss 2. The construction personnel stand above the single-layer mesh cover structure 7. When the reinforcement component 8 is moved to the area to be reinforced, the construction personnel can control the reeling mechanism 6 to lower the reinforcement component 8 to the top of the single-layer mesh cover structure 7 to achieve the installation of the reinforcement component 8 with the original mesh cover structure. The specific installation process of the reinforcement component 8 can be assisted by the construction personnel. The construction personnel stand on the original single-layer mesh cover structure 7 to splice and fix the reinforcement component 8. Regarding the connection between the reinforcement component and the original mesh cover structure, it is a conventional choice in the construction field. Different connection methods can be selected according to the structural bearing capacity requirements. The reinforcement component can be welded to the original mesh cover structure, or a connector can be set at the original mesh cover structure to achieve the connection between the reinforcement component and the original mesh cover structure. The general principle is to meet the structural stress calculation.

[0032] Step 4: After all the reinforcement components 8 within the coverage area of ​​the assembled truss 2 have been constructed, the pushing mechanism 4 is used to drive the assembled truss 2 to rotate along the sliding track 1, and steps 2 to 3 are repeated until the entire mesh cover structure 7 is covered and reinforced, and finally a double-layer mesh structure is formed.

[0033] The present invention utilizes the assembly truss 2 to transport the reinforcement components 8, which on the one hand enables the simultaneous movement and installation of multiple reinforcement components 8, improving construction efficiency; on the other hand, the assembly truss 2 of this application occupies little space and reduces the use of large hoisting machinery, making it more economical and having less impact on the normal use of the building.

[0034] In addition, under the working conditions of the background technology of this application, when installing the reinforcement 8, the reinforcement 8 can be transported directly from the ground to the top of the single-layer mesh cover and fixed, and the reinforcement 8 can be installed symmetrically from the edge to the middle area.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
