Description

Technical Field

[0001] This application relates to the technical field of building construction structures, and particularly to a cable-net wood formwork construction platform. Background Art

[0002] With the continuous development of building construction technology, the shapes of existing building structures have become diverse. In the design and construction of building atriums, there often appear some unique-shaped roof structures, such as: arch-shaped, saddle-shaped, and so on.

[0003] In the indoor atrium project of high-rise buildings, the method of setting up building hanging baskets or full hall scaffolds is usually adopted to provide a construction platform for construction workers. Among them, the way of setting up hanging baskets is mainly to install a lifting device on the structure of the high-rise building, and use the lifting device to drive the hanging basket to move to the high-rise, so as to provide a working platform for construction workers. The full hall scaffold mainly forms a support frame with a height close to the height of the roof by fixing a large number of cross bars and vertical poles to each other, and then sets up formwork on the support frame to form a construction platform.

[0004] However, both of the above two methods have certain limitations. For example, the hanging basket is generally set along the outer edge of the building, and it cannot cover the construction of large-span roofs. Although the full hall scaffold can adapt to the construction of large-span roofs; however, the full hall scaffold needs to be set up from the lower building structure; this results in a large construction cost for setting up the full hall scaffold and a long construction period. Therefore, how to reduce the construction cost and shorten the construction period while meeting the requirements of large-span roof construction is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0005] In order to reduce the construction cost and shorten the construction period on the premise of meeting the construction of large-span roofs, this application provides a cable-net wood formwork construction platform.

[0006] A cable-net wood formwork construction platform provided by this application adopts the following technical solutions:

[0007] A cable-net wood formwork construction platform includes a stress cable net, a soft platform, and a scaffold. The stress cable net includes a plurality of connecting steel cables, and the connecting steel cables are connected to each other to form a stress cable net. The connecting steel cables are connected to the building structure. The soft platform is laid on the stress cable net. There are connecting pieces on the soft platform. The connecting pieces include limiting steel bars. The limiting steel bars are connected to the soft platform. The limiting steel bars are perpendicular to the soft platform. The end of the vertical pole of the scaffold is sleeved on the limiting steel bar.

[0008] By adopting the above technical solution, a tensioned cable net is installed at different heights on the building structure, and a soft platform is then laid on the tensioned cable net to form a support platform. Spacers are connected to the soft platform, and the scaffolding uprights are mounted on the limiting steel bars to connect the soft platform to the scaffolding. The limiting steel bars also limit the horizontal displacement of the scaffolding components, improving the stability of the scaffolding during use and reducing the occurrence of construction accidents. The cable net and soft platform allow construction workers to set up the scaffolding at different heights according to actual conditions, thereby reducing the height of the scaffolding, reducing construction costs, and shortening the construction period.

[0009] Optionally, a fixing block is provided on the floor slab of the building structure, an embedded part is pre-embedded and connected to the fixing block, and the connecting steel cable is tied to the embedded part.

[0010] By adopting the above technical solution, a fixed block is set on the floor slab, and embedded parts are set in the fixed block, thereby providing a force point for the connection of the steel cable, facilitating the installation of the force-bearing cable net, and improving the efficiency of construction workers in building the platform.

[0011] Optionally, a structural beam is provided on the building structure, and the end of the connecting steel cable corresponds to the structural beam. The building structure includes a floor slab, and a connecting hole is opened on the floor slab corresponding to the connecting steel cable. The end of the connecting steel cable passes through the connecting hole and is wrapped around the structural beam.

[0012] By adopting the above technical solution, the connecting steel cables are passed through the connection holes and wrapped around the structural beams, effectively utilizing the structure of the building structure. Moreover, due to the superior strength of the structural beams themselves, the load-bearing cable net is more stable during use, reducing the occurrence of safety accidents.

[0013] Optionally, the soft platform includes a lower template and an upper template, the upper template and the lower template are parallel to each other, and multiple wooden beams are arranged between the upper template and the lower template in a direction parallel to the upper template. The upper template is provided with a steel structure for connecting the upper template and the wooden beams, and the wooden beams are provided with a wire structure for tying the wooden beams and the lower template to the force-bearing cable net.

[0014] By adopting the above technical solution, when setting up the platform, the lower formwork is laid on the tensioned cable net to form a relatively flat platform above the tensioned cable net. Then, multiple wooden beams are set in a direction parallel to the lower formwork. The wooden beams and the tensioned cable net are tied together using a wire structure to achieve the connection between the wooden beams, the lower formwork, and the tensioned cable net. Finally, the upper formwork is fixed to the wooden beams via a steel structure to complete the foundation of the platform. Moreover, due to the inherent hardness of the wooden beams, it is convenient for construction workers to use steel structures to connect the upper formwork to the wooden beams. In addition, the wooden beams are low-cost and reusable, further reducing costs during the construction process.

[0015] Optionally, a rope fixing structure is provided at the end of the connecting cable. The end of the connecting cable is connected to itself through a rope fixing mechanism. The rope fixing mechanism includes a mounting shell, a first limiting component, and a second limiting component. The connecting cable includes a first connecting portion and a second connecting portion. The first connecting portion is the part close to the end of the connecting cable. Two cable holes are provided on the mounting shell. The first connecting portion and the second connecting portion are respectively inserted into the two cable holes. The first limiting component is used to limit the first connecting portion, and the second limiting component is used to limit the second connecting portion.

[0016] By adopting the above technical solution, after the connecting cable is wound around the embedded part or the structural beam, it is fixed to itself through the rope fixing mechanism, improving the stability of the installation of the stressed cable net. During use, the end of the connecting cable is sequentially passed through the two cable holes to form a first connecting portion and a second connecting portion. The first lower limiting component and the second limiting component respectively limit the first connecting portion and the second connecting portion, thereby preventing the connecting cable from disengaging from the cable holes of the mounting shell, realizing the fixation of the end of the connecting cable to itself, and further realizing the fixed connection between the two sections of the cable and the embedded part or the structural beam.

[0017] Optionally, the first limiting component includes a mounting cylinder and a limiting rod. The mounting cylinder is arranged along the length direction of the first connecting portion and sleeved outside the first connecting portion. One end of the limiting rod is rotatably connected to the outer side wall of the mounting cylinder, and the other end extends in the opposite direction of the moving trend of the first connecting portion when the stressed cable net is stressed and inclines towards the first connecting portion; an avoidance groove is provided at the corresponding position of the mounting cylinder for the limiting rod; a plurality of fixing rings are arranged on the connecting cable along the length direction of the connecting cable, and one end of the limiting rod close to the first connecting portion passes through the avoidance groove and abuts against the fixing ring.

[0018] By adopting the above technical solution, one end of the limiting rod close to the first connecting portion abuts against the fixing ring, thereby blocking the first connecting portion from disengaging from the cable hole. In addition, the limiting rod extends in the opposite direction of the moving trend of the first connecting portion; when the stressed cable net is stressed, the fixing tube applies a force along the moving trend of the first connecting portion to one end of the limiting rod close to the first connecting portion. Under the action of the force, one end of the limiting rod close to the first connecting portion has a tendency to rotate towards the first connecting portion, thereby making the limiting rod further press against the first connecting portion and improving the stability of the fixation of the first connecting portion and the second connecting portion.

[0019] Optionally, a plurality of the limiting rods are arranged around the axis of the connecting cable.

[0020] By adopting the above technical solution, a plurality of limiting rods simultaneously abut against the fixing ring, thereby improving the stability of the first limiting component in limiting the first connecting portion.

[0021] Optionally, the first limiting component further includes an elastic member, which is installed on the limiting rod and is used to keep one end of the limiting rod close to the connecting portion in a tendency to rotate towards the first connecting portion.

[0022] By adopting the above technical solution, when the connecting cable is passed through from one side of the installation shell, the fixing ring drives one end of the limiting rod close to the first connecting portion to rotate away from the first connecting portion. After the fixing ring passes the limiting rod, the limiting rod can automatically abut against the fixing ring under the action of the elastic member, thereby facilitating the construction personnel to fix the connecting cable, improving the efficiency of the construction personnel in erecting the construction platform, and further shortening the construction period.

[0023] Optionally, an installation cylinder is arranged inside the installation shell along the length direction of the first connecting portion. A moving component is arranged on the installation cylinder. The moving component includes a driving ring and a sliding ring. The driving ring is threadedly connected to the installation cylinder. The sliding ring is rotatably connected to the driving ring, and the sliding ring can slide along the length direction of the installation cylinder. The limiting rod is connected to the sliding ring. Rotating the driving ring can drive the sliding ring to rotate along the length direction of the installation cylinder.

[0024] By adopting the above technical solution, rotating the driving ring drives the sliding ring to move along the direction of the moving tendency of the first connecting portion, and the sliding ring drives the limiting rod to move. When the limiting rod moves, the side surface close to the first connecting portion abuts against the side surface of the avoidance groove. As the limiting rod moves, one end of the limiting rod close to the first connecting portion moves away from the first connecting portion. When one end of the limiting rod close to the first connecting portion is located outside the fixing ring, the first connecting portion can be detached from the installation shell, thereby facilitating the disassembly of the stressed cable net, enabling the stressed cable net to be reused, and further reducing the construction cost.

[0025] Optionally, the second connecting portion is parallel to the length direction of the first connecting portion. The second limiting component has the same structure as the first limiting component. The limiting rod in the second limiting component extends in the opposite direction to the limiting rod in the first limiting component. A linkage component is arranged between the first limiting component and the second limiting component. The linkage component includes a driving rod and two toothed rings. The two toothed rings are respectively sleeved on the driving rings of the first limiting component and the second limiting component. The driving rod is arranged along the rotation axis of the driving ring. The driving rod is rotatably connected to the installation shell. A plurality of tooth grooves are arranged on the side surface of the driving rod along its circumferential direction. The toothed rings are engaged with the tooth grooves.

[0026] By adopting the above technical solution, the rotation of the driving rod can drive the two driving rings to rotate simultaneously and move in the direction of approaching or separating from each other. When the force-bearing cable net is under force, the moving trend of the second connecting part is opposite to that of the first connecting part. Therefore, the extending directions of the limiting rods in the first limiting component and the second limiting component are opposite, so as to realize the fixation of the first connecting part and the second connecting part. Rotating the driving rod drives the two gear rings meshing with it to rotate, and then drives the two driving rings to rotate simultaneously, realizing the simultaneous adjustment of the sliding ring positions of the first limiting component and the second limiting component, improving the efficiency of construction workers when installing or disassembling the force-bearing cable net, and further shortening the construction period.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Set the force-bearing cable nets at different heights of the building structure, and then fix the lower formwork wooden beams and the upper formwork on the force-bearing cable nets to form a flat support platform. Construction workers can set up scaffolding on the platform for construction. Through the force-bearing cable nets, scaffolding can be set up from different heights, thereby reducing the height of the scaffolding erection, shortening the construction period, and reducing the construction cost;

[0029] 2. When one end of the connecting steel cable passes through the steel cable hole on the installation shell, the fixing ring abuts against the limiting rod, and drives the end of the limiting rod close to the connecting steel cable to rotate away from the connecting steel cable, so that the limiting rod automatically gives way to the movement of the connecting steel cable. When the fixing ring moves to the other side of the limiting rod, under the action of the elastic member, the limiting rod automatically abuts against one side of the fixing ring, thereby realizing the rapid fixation of the force-bearing cable net, and thus shortening the construction period.

Detailed implementation manners

[0039] The following will Figure 1-8 further describe the present application in detail.

[0040] An embodiment of the present application discloses a cable net wooden formwork construction platform.

[0041] Referring to Figure 1 , a cable net wooden formwork construction platform includes a stress cable net 1 and a soft platform 2, and the stress cable net 1 is connected to a building structure. The stress cable net 1 is arranged parallel to the ground, the soft platform 2 is a plate-like structure as a whole, and the soft platform 2 is laid on the cable net. A scaffolding 24 is arranged on the soft platform 2, and construction workers can construct the roof on the scaffolding 24. Of course, in other embodiments, construction workers can also directly construct the roof of the building on the soft platform 2. The stress cable net 1 and the soft platform 2 are used to support the scaffolding 24, so that construction workers can set up the scaffolding 24 at any height according to construction requirements, thereby reducing the height of the scaffolding 24, achieving the effects of reducing construction costs and shortening the construction period.

[0042] Referring to Figure 1 and Figure 2, in this embodiment, an oval roof is taken as an example, and the stress cable net 1 is integrally set as an oval according to the construction environment. The stress cable net 1 includes a plurality of connecting cables 11, and the plurality of connecting cables 11 are connected to each other to form the stress cable net 1. A structural beam 41 is connected to the floor slab 4 of the building structure. A connection hole 43 is formed in the floor slab 4 near the structural beam 41, and a buried part 3 is also provided on the building floor slab 4. The connecting cable 11 is connected in the connection hole 43 or to the buried part 3, and the connection method between the connecting cable 11 and the building structure depends on the building structure. Among them, the long-axis cable 12 or the short-axis cable 13 corresponding to the structural beam 41 is connected to the building structure through the connection hole 43. If there is no structural beam 41 at the floor slab 4 corresponding to the end of the short-axis cable 13 and the long-axis cable 12, the short-axis cable 13 or the long-axis cable 12 is connected to the building structure through the buried part 3.

[0043] Refer to Figure 1 and Figure 2 , in this embodiment, the connecting cables 11 are divided into two groups, namely the long-axis cables 12 and the short-axis cables 13. The long-axis cables 12 refer to the cables parallel to the long axis of the stress cable net 1, and the short-axis cables 13 refer to the cables parallel to the short axis of the stress cable net 1. In other embodiments, the stress cable net 1 as a whole can be rectangular. In the rectangular stress cable net 1, the short-axis cables 13 refer to the connecting cables 11 parallel to the width direction of the stress cable net 1, and the long-axis cables 12 refer to the connecting cables 11 parallel to the length direction of the stress cable net 1. The long-axis cables 12 are located above the short-axis cables 13, the long-axis cables 12 and the short-axis cables 13 are perpendicular to each other, and the intersection of the long-axis cables 12 and the short-axis cables 13 is welded to form a mesh structure. In other embodiments, other connection methods can also be adopted between the long-axis cables 12 and the short-axis cables 13, such as wire binding, wire rope clamps, etc. The long-axis cables 12 are connected to the buried part 3, and the short-axis cables 13 correspond to the structural beam 41 of the building structure and are connected in the through holes. When the stress cable net 1 is stressed, the short-axis cables 13 bear the main load, and the long-axis cables 12 disperse the concentrated load on the upper part, thereby reducing the situation of rope loosening or end breakage caused by excessive stress in the length direction of the long-axis cables 12.

[0044] Refer to Figure 1 and Figure 2 , the structural beam 41 is located on one side of the floor slab 4 close to the stress cable net 1. The end of the short-axis cable 13 extends horizontally. When the end of the short-axis cable 13 corresponds to the connection hole 43, it extends vertically downward and winds around the structural beam 41 for one week. A rope fixing mechanism 6 is provided at the end of the short-axis cable 13. The rope fixing mechanism 6 fixes the part of the end of the short-axis cable 13 that coincides with the short-axis cable 13, realizing the connection between the short-axis cable 13 and the building structure. In this embodiment, the rope fixing mechanism 6 is a wire rope clamp (the specific structure of the wire rope clamp is not shown in the figure), and the two clamping parts of the wire rope clamp clamp the end of the short-axis cable 13 and itself.

[0045] Referring to Figure 1 , at the position on the structural beam 41 corresponding to the short-axis cable 13, a protective sleeve 42 is provided. The protective sleeve 42 includes a vertical portion and a horizontal portion, and both the horizontal portion and the vertical portion are circular cylindrical structures. The vertical portion is provided in two, and the two vertical portions are respectively perpendicular to the horizontal portion and are provided at both ends of the horizontal portion, and are integrally formed with the horizontal portion to form a U shape. The horizontal portion is tangent to the side surface of the structural beam 41 close to the ground, and the vertical portion is tangent to the side surface of the structural beam 41 perpendicular to the ground. The short-axis cable 13 is threaded through the protective sleeve 42, thereby preventing the short-axis cable 13 from directly contacting the structural beam 41, reducing the wear of the short-axis steel cable during use, and improving the stability of the stress cable net 1 during use.

[0046] Referring to Figure 1 , when the stress cable net 1 is stressed, the part of the short-axis cable 13 located in the connection hole 43 has a tendency to move upward, and the force received by the stress cable net 1 during the construction process is not a continuously constant force. Therefore, the short-axis cable 13 wound around the structural beam 41 is likely to move around the structural beam 41. In order to reduce the occurrence of the above situation, a blocking member is provided at the position on the short-axis cable 13 corresponding to the connection hole 43, and the blocking member is located below the floor slab 4 of the building structure. The blocking member is used to prevent the short-axis cable 13 wound around the structural beam 41 from moving. In this embodiment, the blocking member is a wire rope buckle fixedly connected to the short-axis cable 13, and the side of the wire rope buckle close to the floor slab 4 abuts against the bottom surface of the floor slab 4, thereby preventing the short-axis cable 13 from moving when the stress cable net 1 is stressed, and further reducing the occurrence of serious wear of the short-axis cable 13.

[0047] Referring to Figure 1 , Figure 2 and Figure 3 , the embedded part 3 includes an ear plate 31, a connecting plate 32 and an embedded rod 33. The ear plate 31 and the embedded rod 33 are respectively arranged on both sides of the connecting plate 32, and the embedded rod 33 is perpendicularly welded to the connecting plate 32 on the connecting plate 32. The side of the ear plate 31 close to the connecting plate 32 is welded to the connecting plate 32, and a through hole is provided in the ear plate 31. A fixing block is cast on the floor slab 4 at the position corresponding to the long-axis cable 12, and the embedded rod 33 is pre-cast inside the fixing block. The end of the long-axis cable 12 passes through the through hole on the ear plate 31 and is fixed to itself by a cable fixing structure, realizing the fixed connection between the long-axis cable 12 and the building structure. In order to improve the connection strength between the embedded part 3 and the fixing block, a blocking block is welded on the embedded part. Through the blocking block 34, the contact area between the embedded part 3 and the concrete can be increased, and the embedded rod 33 can also be blocked from coming out of the embedded part 3.

[0048] Referring to Figure 1 and Figure 4, the soft platform 2 includes a lower formwork 23, an upper formwork 21 and a plurality of wooden beams 22. The lower formwork 23 is laid on the stress cable net 1. The lower formwork 23, the upper formwork 21 and the wooden beams 22 are all made of wood. The wooden beams 22 are in a rectangular rod-shaped structure, and a plurality of wooden beams 22 are arranged at intervals in the horizontal direction on the side of the lower formwork 23 away from the stress cable net 1. A silk thread structure 26 is arranged on the wooden beams 22, and the wooden beams 22 and the lower formwork 23 are tied to the stress cable net 1 through the silk thread structure 26. In this embodiment, the silk thread structure 26 is a wire. Through holes are formed in the lower formwork 23. One end of the wire passes through the through holes and the mesh holes on the stress cable net 1 in sequence and is fixedly connected to the other end, so as to realize the fixed connection between the lower formwork 23, the stress cable net 1 and the wooden beams 22. The upper formwork 21 is laid on the side of the wooden beams 22 away from the lower formwork 23. A steel structure 25 is arranged on the upper formwork 21, and the upper formwork 21 is connected to the wooden beams 22 through the structure. In this embodiment, steel nails are used to fixedly connect the upper formwork 21 to the wooden beams 22.

[0049] Referring to Figure 1 and Figure 5 , a connecting member 5 for connecting the scaffolding 24 is arranged on the upper formwork 21. The connecting member 5 includes a gasket 51 and a limiting steel bar 52. The gasket 51 is fixedly connected to the upper surface of the upper formwork 21 through a steel nail. The gasket 51 is in a square plate-shaped structure and is parallel to the upper formwork 21 and fits with the upper formwork 21. The limiting steel bar 52 is vertically welded to the gasket 51. The end of the vertical rod of the scaffolding 24 is sleeved on the limiting steel bar 52 to realize the connection between the scaffolding 24 and the soft platform 2. Moreover, the limiting steel bar 52 can limit the horizontal displacement of the scaffolding 24 and improve the stability of the scaffolding 24 during use. In order to further improve the stability of the scaffolding 24 during use, a connecting steel pipe is arranged on the side of the scaffolding 24. One end of the connecting steel pipe is fixedly connected to the side of the scaffolding 24 and the other end is fixedly connected to the floor slab 4 of the building structure. Thus, the scaffolding 24 can be supported from the side.

[0050] The implementation principle of a cable net wooden formwork construction platform in an embodiment of the present application is as follows: when the construction platform is erected, the connection methods of the short-axis ropes 13 and the long-axis ropes 12 of the stress cable net 1 with the existing building structure are determined according to the existing building structure. The ends of the short-axis ropes 13 and the long-axis ropes 12 of the stress cable net 1 are fixedly connected to the existing building structure. After the stress cable net 1 is connected, the lower formwork 23, the wooden beams 22 and the upper formwork 21 are sequentially laid on the stress cable net 1. Before laying the upper formwork 21, the wooden beams 22, the lower formwork 23 and the stress cable net 1 are tied and fixed with wires. After the upper formwork 21 is laid, the upper formwork 21 is fixedly connected to the wooden beams 22 with steel nails. After the upper formwork 21 is fixed, the gasket 51 is fixedly connected to the upper formwork 21 according to the size of the scaffolding 24. After the gasket 51 is fixed, the scaffolding 24 can be erected on the gasket 51 for construction.

[0051] Example 2

[0052] Referring to Figure 6 , the difference between this embodiment and Embodiment 1 lies in the different structure of the rope fixing mechanism 6.

[0053] Referring to Figure 6 and Figure 7 , in this embodiment, the connection between the long-axis rope 12 and the embedded part 3 is described. In this embodiment, the rope fixing mechanism 6 includes a mounting shell 61, a first limiting component 62 and a second limiting component 63. Two through circular cable holes 65 are formed in the mounting shell 61. After the end of the long-axis rope 12 passes through the through hole on the ear plate 31, a first connection part 121 and a second connection part 122 are formed. The length directions of the first connection part 121 and the second connection part 122 are parallel to each other. Among them, the first connection part 121 is the part close to the end of the long-axis rope 12. The first connection part 121 and the second connection part 122 are respectively arranged in the two cable holes 65. The first limiting component 62 and the second limiting component 63 are both installed on the mounting shell 61. The first limiting component 62 is used to lock and limit the first connection part 121. The second limiting component 63 is used to lock and limit the second connection part 122. By the first limiting component 62 and the second limiting component 63, the relative displacement between the long-axis rope 12 and the mounting shell 61 is blocked, and the long-axis rope 12 is blocked from disengaging from the mounting shell 61, so as to prevent the long-axis rope 12 from detaching from the ear plate 31.

[0054] Referring to Figure 6 , a plurality of fixing rings 64 are arranged on the first connection part 121 and the second connection part 122. The plurality of fixing rings 64 are evenly spaced along the length directions of the first connection part 121 and the second connection part 122. The inner side wall of the fixing ring 64 is attached to and welded with the first connection part 121 or the second connection part 122.

[0055] Referring to Figure 6 , Figure 7 and Figure 8, when the stress cable net 1 is stressed, the second connecting portion 122 has a tendency to move away from the embedded part 3 along its own length direction, and the first connecting portion 121 has a tendency to move towards the embedded part 3 along its own length direction. The first limiting component 62 includes an installation cylinder 621 and a limiting rod 622. The installation cylinder 621 is a circular cylindrical structure, and the installation cylinder 621 is coaxially arranged with the first connecting portion 121. Both ends of the installation cylinder 621 are welded to two parallel inner side walls inside the installation shell 61 respectively. One end of the limiting rod 622 is rotatably connected to the outer side wall of the installation cylinder 621 through a rotating shaft, and the other end inclines towards the first connecting portion 121 in the opposite direction of the moving trend of the first connecting portion 121. An avoidance hole is provided at the position corresponding to the limiting rod 622 on the installation cylinder 621, and the end of the limiting rod 622 far from the sliding ring 71 passes through the avoidance hole and abuts against the side wall of the first connecting portion 121. When the stress cable net 1 is stressed, the limiting rod 622 abuts against the side of the fixed ring 64 close to the embedded part 3, thereby blocking the first connecting portion 121 from moving towards the embedded part 3.

[0056] Referring to Figure 6 , Figure 7 and Figure 8 , multiple limiting rods 622 can be evenly spaced along the circumferential direction of the installation cylinder 621. In this embodiment, the number of limiting rods 622 is set to eight. The multiple limiting rods 622 lock the first connecting portion 121 simultaneously, thereby improving the stability of the first limiting component 62 in limiting the first connecting portion 121. In addition, when the stress cable net 1 is stressed, the first connecting portion 121 has a tendency to move towards the embedded part 3. Therefore, the fixed ring 64 on the first connecting portion 121 that abuts against the limiting rod 622 exerts a tightening force on the limiting rod 622 (in this embodiment, the tightening force refers to the force in the direction along the length of the first connecting portion 121 towards the embedded part 3), so that the end of the limiting rod 622 far from the sliding ring 71 has a tendency to rotate towards the axis of the first connecting portion 121; further, the limiting rod 622 is further tightened against the side of the first connecting portion 121, improving the stability of the first limiting component 62 in locking and fixing the first connecting portion 121.

[0057] Referring to Figure 2, the first limiting component 62 further includes an elastic member 623. The elastic member 623 is used to keep the end of the limiting rod 622 away from the sliding ring 71 in a tendency to rotate towards the axis of the first connecting portion 121. In this embodiment, the elastic member 623 is a torsion spring. The torsion spring is sleeved on the rotating shaft of the limiting rod 622, and one end of the torsion spring is welded to the limiting rod 622, and the other end is connected to the mounting cylinder 621. Under the action of the torsion spring, the end of the limiting rod 622 away from the sliding ring 71 can stably abut against the fixed ring 64. Moreover, during the process of passing the first connecting portion 121 through the steel cable hole 65, the limiting rod 622 can automatically rotate and always abut against the side surface of the first connecting portion 121, which is convenient for the construction personnel to fix the long-axis rope 12.

[0058] Referring to Figure 6 , Figure 7 and Figure 8 , in order to facilitate the disassembly of the stressed cable net 1, a moving component 7 is arranged on the mounting cylinder 621. The moving component 7 includes a sliding ring 71 and a driving ring 72. The sliding ring 71 is of an annular structure. The sliding ring 71 is coaxially sleeved on the mounting cylinder 621, and the sliding ring 71 can slide along the axis direction of the mounting cylinder 621. The end of the limiting rod 622 away from the first connecting portion 121 is connected to the sliding ring 71. The driving ring 72 is of an annular structure. The driving ring 72 is coaxially sleeved on the mounting cylinder 621. The driving ring 72 is located on the side of the sliding ring 71 away from the limiting rod 622. The side surface of the driving ring 72 close to the sliding ring 71 is attached to the sliding ring 71, and the driving ring 72 is rotatably connected to the sliding ring 71. Internal threads are arranged on the inner side wall of the driving ring 72, and external threads are arranged on the mounting cylinder 621 at the position corresponding to the driving ring 72. The driving ring 72 is threadedly connected to the mounting cylinder 621. Rotating the driving ring 72 can drive the sliding ring 71 to move along the axis of the mounting cylinder 621. When the stressed cable net 1 needs to be disassembled, rotate the driving ring 72 to make the sliding ring 71 move in the direction of the moving trend of the first connecting portion 121. During the movement of the sliding ring 71, the side surface of the limiting rod 622 close to the first connecting portion 121 abuts against the side wall of an avoidance hole. As the sliding ring 71 moves, the end of the limiting rod 622 away from the sliding ring 71 rotates in the direction away from the axis of the first connecting portion 121, so that the limiting rod 622 is disengaged from the fixed ring 64, realizing the disassembly of the stressed cable net 1.

[0059] Referring to Figure 6 , Figure 7 and Figure 8 , the second limiting component 63 has the same structural principle as the first limiting component 62. The second limiting component 63 is correspondingly arranged for the second connecting portion 122, and the extending directions of the limiting rods 622 of the first limiting component 62 and the second limiting component 63 are opposite.

[0060] Referring to Figure 6 , Figure 7 and Figure 8To simultaneously adjust the positions of the two sliding rings 71, a linkage assembly 8 is also provided within the mounting housing 61. The linkage assembly 8 comprises a ring gear 81 and a drive rod 82. The drive rod 82 is a cylindrical rod-shaped structure located between the two mounting barrels 621, with its axis parallel to the direction of movement of the sliding rings 71. The two end faces of the drive rod 82 are rotatably connected to two mutually parallel side surfaces within the mounting housing 61. Two ring gears 81 are provided, corresponding to the drive rings 72 of the first and second position-limiting assemblies 62 and 63. The ring gears 81 are coaxially sleeved on the drive rings 72 and welded to the drive rings 72. Multiple tooth grooves are provided on the side surfaces of the drive rods 82 along their circumference, and the ring gears 81 engage within the tooth grooves. Rotating the drive rod 82 causes the two ring gears 81 to rotate simultaneously, thereby driving the two drive rings 72 to rotate simultaneously. Driven by the threaded structure, the two drive rings 72 can simultaneously move toward or away from each other in a direction parallel to the axis of the mounting barrels 621.

[0061] Reference Figure 6 、 Figure 7 and Figure 8 The linkage assembly 8 also includes a dial wheel 83, which is coaxially welded to the drive rod 82, and the diameter of the dial wheel 83 is larger than the diameter of the drive rod 82. A dial hole 84 is provided on the mounting shell 61 at a position corresponding to the dial wheel 83, and the dial hole 84 is connected to the inside of the mounting shell 61. Construction personnel can dial the dial wheel 83 from the outside of the mounting shell 61 to control the rotation of the drive rod 82. Rectangular baffles are provided on both sides of the dial hole 84 parallel to the axis of the drive rod 82, and one side of the baffle in the length direction is welded to the side of the dial hole 84 parallel to the axis of the drive rod 82, and the other side of the baffle in the length direction is bent toward the direction close to the dial wheel 83. Guard plates are provided on both sides of the baffle perpendicular to the axis of the drive rod 82, and the guard plates connect the two baffles at the same time. This can prevent dust from entering the interior of the mounting shell 61 through the dial hole 84.

[0062] Reference Figure 2 The aforementioned rope securing mechanism 6 can also secure the connection between the stub rope 13 and the building structure (this state is not shown in the figure). When securing the stub rope 13, attention must be paid to the threading arrangement between the stub rope 13 and the mounting housing 61. The two portions of the stub rope 13 threaded through the two cable holes 65 must move in opposite directions when the load-bearing cable net 1 is subjected to force.

[0063] The implementation principle of the cable-net wood formwork construction platform in an embodiment of this application is as follows: When installing the stress cable-net 1, first pass the long-axis rope 12 through one of the steel cable holes 65 of the installation shell 61. During the passing process, the fixing ring 64 fixedly connected to the long-axis rope 12 moves from the side of the driving ring 72 away from the limiting rod 622 to the side close to the limiting rod 622 along the extending direction of the limiting rod 622. During the movement of the fixing ring 64, the fixing ring 64 abuts against the side surface of the limiting rod 622 close to the long-axis rope 12 and drives the limiting rod 622 to rotate. After the long-axis rope 12 passes through the installation shell 61, it then passes through the through-hole on the ear plate 31 of the embedded part 3, and finally the end of the long-axis rope 12 passes through another steel cable hole 65 to complete the installation of the stress cable-net 1. During the movement of the long-axis rope 12 in the steel cable hole 65, after the fixing ring 64 passes the limiting rod 622, the limiting rod 622 can automatically abut against the long-axis rope 12, thereby preventing the long-axis rope 12 from detaching from the steel cable hole 65 and realizing the rapid connection between the stress cable-net 1 and the building structure.

[0064] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
