Description
Technical Field
[0001] This utility model relates to the field of pipe gallery construction technology, and in particular to a mobile support system for pipe gallery formwork. Background Technology
[0002] Urban integrated utility tunnels are part of modern urban infrastructure. They refer to a tunnel space built underground in a city that integrates various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage. They are equipped with dedicated maintenance ports, hoisting ports and monitoring systems for unified planning, design, construction and management.
[0003] Typically, urban integrated utility tunnels can be constructed using formwork trolleys for formwork erection and pouring. However, for some utility tunnels with smaller cross-sectional dimensions (e.g., cross-sectional dimensions less than 6×5m), formwork trolleys occupy a large area, are cumbersome to operate, and are inconvenient to carry out work. Therefore, utility tunnels with smaller cross-sectional dimensions are usually supported by full-span scaffolding.
[0004] The full-span scaffolding is a fixed scaffolding system. After the construction of one work section is completed, it needs to be disassembled and moved to the next work section for reassembly, which causes inconvenience to construction and is not conducive to the construction schedule. Therefore, a mobile support system for pipe gallery formwork is needed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the problem that existing pipe corridors with small cross-sectional dimensions typically use full-span scaffolding for formwork support. However, full-span scaffolding is a fixed support system, which requires disassembly and reassembly to be moved to the next work area after the completion of construction in one work area, causing inconvenience to construction and hindering the progress of the project. This utility model provides a mobile support system for pipe corridor formwork.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A mobile support system for utility tunnel formwork includes: Several sets of supports are arranged sequentially along the axial direction of the pipe gallery. Adjacent supports are connected by connecting rods. Each set of supports includes at least two segments, which are connected sequentially along the axial direction of the pipe gallery. Each segment includes a vertical rod and a horizontal rod. The bottom end of the vertical rod is connected to a foot support via a telescopic component, and the top end of the vertical rod is connected to a top support via the telescopic component. The mobile component includes wheels, a support tube, and a first fastener. The support tube is detachably connected to the lower part of the support and is arranged laterally along the pipe gallery. The wheels are detachably connected to the vertical bar on the side of the support. The first fastener is detachably connected to the support and the raised foot support. The formwork support assembly includes a main beam and secondary beams. The main beam is detachably connected to the top support. The main beam is arranged laterally along the pipe gallery, and several main beams are spaced apart along the axial direction of the pipe gallery. The secondary beam is detachably connected to the top of the main beam. The secondary beam is arranged axially along the pipe gallery, and several secondary beams are spaced apart along the transverse direction of the pipe gallery. The secondary beams are used to support the formwork.
[0007] The mobile support system for pipe gallery formwork described in this utility model forms a support system for the pipe gallery formwork through a bracket. It is suitable for pipe galleries with small cross-sectional dimensions. The height of the foot supports and top supports can be adjusted by incorporating telescopic components. The detachable wheels and height-adjustable foot supports allow the bracket to switch between support and mobile modes. After supporting work in one work section is completed, it switches to mobile mode to move to the next work section for support, eliminating the need for complete disassembly, transportation, and reinstallation of the entire bracket. The multi-segment design strengthens the structural strength of the bracket, preventing support issues during mode switching. When the frame deforms and switches to mobile mode, the support structure is reinforced by scaffold tubes to prevent excessive lateral bending moment between the wheels from damaging the support. The first fastener supports the foot supports to prevent them from touching the ground and causing obstruction. The longitudinal and transverse arrangement of the main beams and secondary beams ensures that the support can effectively support the formwork. Adjacent supports are connected by connecting rods. If the connecting rods are of the same length, the adjacent supports are arranged along the axis of the pipe gallery, which is suitable for straight sections of the pipe gallery. If one connecting rod is longer than the other, the axes of the adjacent supports have an angle, which is suitable for curved sections of the pipe gallery. This mobile support system has a simple structure, is easy to use, and has good results.
[0008] As a preferred technical solution of this utility model, the telescopic component includes a threaded sleeve and a first screw. The threaded sleeve is connected to the end of the vertical rod, and the first screw is threadedly connected to the threaded sleeve. The first screw is connected to the foot support or the top support.
[0009] As a preferred technical solution of this utility model, the bracket is provided with a wall support, and the wall support is connected to the side of the bracket through the telescopic component.
[0010] As a preferred technical solution of this utility model, the bracket further includes a diagonal bar, the two ends of which are connected to the joints where the vertical bar and the horizontal bar intersect.
[0011] As a preferred technical solution of this utility model, the main beam includes two channel steels with opposite openings and a gap between them. The ends of the two channel steels are welded together by end plates.
[0012] As a further preferred technical solution of this utility model, the top support includes a U-shaped part, the main beam is disposed in the groove of the U-shaped part, and the main beam is detachably connected to the U-shaped part by a second fastener.
[0013] As a further preferred technical solution of this utility model, the second fastener includes a pressure plate, a second screw, a washer, and a nut. The bottom of the U-shaped part is provided with a through hole, and the washer is provided at the bottom of the through hole. The pressure plate is pressed against the top of the two channel steels. The second screw passes through the pressure plate, the gap, the through hole, and the washer and is locked by the nut.
[0014] As a preferred technical solution of this utility model, the secondary beam is detachably connected to the top of the main beam by a third fastener, and the two sides of the secondary beam are provided with through grooves along the length direction, and the third fastener extends into the through grooves.
[0015] As a further preferred technical solution of this utility model, the third fastener includes two fastener plates. One fastener plate has a slot at its bottom and the other fastener plate has a tooth at its bottom. The tooth and the slot cooperate. The top of the fastener plate is bent and can extend into the through groove. The side of the fastener plate has a slot that engages with the main beam. One of the fastener plates is locked to the main beam by a third bolt.
[0016] As a further preferred technical solution of this utility model, the side of the secondary beam is provided with two through grooves near the top and bottom respectively.
[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This utility model discloses a mobile support system for pipe gallery formwork. The system, formed by a bracket, is suitable for pipe galleries with small cross-sectional dimensions. Telescopic components allow for height adjustment of the foot supports and top supports. Detachable wheels and height-adjustable foot supports enable the bracket to switch between support and mobile modes. After supporting work in one section is completed, it switches to mobile mode to move to the next section without requiring complete disassembly, transportation, and reinstallation. Multi-segment design strengthens the structural integrity of the bracket, preventing damage during mode switching. When the system deforms and switches to mobile mode, the support structure is reinforced by scaffolding pipes to prevent excessive lateral bending moments between the wheels from damaging the support. The first fastener supports the foot braces to prevent them from touching the ground and causing obstruction. The longitudinal and transverse arrangement of the main beams and secondary beams ensures that the support can effectively support the formwork. Adjacent supports are connected by connecting rods. If the connecting rods are of the same length, the adjacent supports are arranged along the axis of the pipe gallery, which is suitable for straight sections of the pipe gallery. If one connecting rod is longer than the other, the axes of the adjacent supports have an angle, which is suitable for curved sections of the pipe gallery. This mobile support system has a simple structure, is easy to use, and has good performance. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.
[0021] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.
[0022] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0025] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.
[0026] In related technologies, existing pipe galleries with smaller cross-sectional dimensions typically use full-span scaffolding for formwork support. However, full-span scaffolding is a fixed system, requiring disassembly and reassembly after completion of one work section, which causes inconvenience and delays the construction schedule. Therefore, the technical solution of this application was developed. The following section combines... Figures 1 to 9 To elaborate.
[0027] Example 1 like Figures 1 to 9 As shown, the mobile support system for pipe gallery formwork of this utility model includes a support frame 1, a mobile component and a formwork support component.
[0028] The support 1 comprises several groups, and the support 1s are arranged sequentially along the axial direction of the pipe gallery, with adjacent support 1s connected by connecting rods 2; as shown in the figure. Figure 2 As shown, the two sections of the utility tunnel are each equipped with a corresponding mobile support system. Figure 2 In the left-side compartment section, adjacent supports 1 are connected by two rows of connecting rods 2. Figure 2 In the right-side compartment, the adjacent supports 1 are connected by four rows of connecting rods 2.
[0029] Each set of the support 1 includes at least two segments 11, which are connected sequentially along the axial direction of the pipe gallery; for example Figure 1 and Figure 2 As shown, in this embodiment, each group of the support 1 includes three segments 11. Figure 1 and Figure 2 The cross-section of the left-middle section is smaller, and each of the segments 11 can be provided with only one inter-segment (along the transverse direction of the pipe gallery). Figure 1 and Figure 2 The cross-section of the right-side compartment is larger, and each segment 11 can be configured with three sections (along the transverse direction of the pipe gallery).
[0030] like Figure 1 and Figure 2 As shown, each segment 11 includes a vertical rod, a horizontal rod, and a diagonal rod, which can be connected using a conventional support frame connection method. For example, several joints are spaced apart on the vertical rod, and the horizontal rod and the diagonal rod are connected to the joint positions.
[0031] like Figure 1 and Figure 4 As shown, the bottom end of the vertical rod is connected to a foot support 12 via a telescopic component; the telescopic component includes a threaded sleeve 16 and a first screw 17, the threaded sleeve 16 is connected to the bottom end of the vertical rod (e.g., by welding), the first screw 17 is threadedly connected to the threaded sleeve 16, and the bottom of the first screw 17 is connected to the foot support 12.
[0032] like Figure 1 and Figure 5 As shown, the top end of the vertical rod is connected to the top support 14 via the telescopic component; the threaded sleeve 16 is connected to the top end of the vertical rod, the first screw 17 is threadedly connected to the threaded sleeve 16, and the top of the first screw 17 is connected to the top support 14.
[0033] like Figure 1 As shown, the support 1 is provided with a wall brace 13, which is connected to the side of the support 1 through the telescopic component; the threaded sleeve 16 is connected to the joint position on the vertical rod, the first screw 17 is threaded to the threaded sleeve 16, and the end of the first screw 17 is connected to the wall brace 13. When the support 1 is supported, the wall brace 13 extends and abuts against the side wall of the pipe gallery.
[0034] like Figure 3 As shown, the moving assembly includes wheels 6, a support tube 7, and a first fastener 15. The support tube 7 is detachably connected to the lower part of the support 1 and is arranged laterally along the pipe gallery, thereby strengthening the lateral structural strength of the support 1. The wheels 6 are detachably connected to the vertical rods on the side of the support 1, specifically by wheel frames connected to the joints on the vertical rods. The first fastener 15 is detachably connected to the support 1 and the raised foot support 12. The first fastener 15 has an L-shaped structure, with its top connected to the joint on the vertical rod and its bottom connected to the first screw 17 corresponding to the foot support 12. It should be noted that... Figure 3 This is a partial cross-sectional view of the utility tunnel. Figure 3 The walking wheel 6 mentioned is only for illustrative purposes; the bracket 1 is not actually installed according to the stated location. Figure 3 Instead of moving in the indicated direction (horizontal of the utility tunnel), it moves in a direction perpendicular to the computer screen.
[0035] After the traveling wheel 6 and the support tube 7 are installed in place, the first screw 17 corresponding to the foot support 12 is turned to lift the foot support 12 off the ground and retract it, and the support 1 switches from the support mode to the moving mode; after moving to the designated position, the foot support 12 is lowered to support the ground, and the traveling wheel 6 and the support tube 7 are removed, so that the support 1 switches from the moving mode to the support mode. Removing the support tube 7 reduces the constraint at the bottom of the support 1, so that the support 1 can carry out the load-bearing operation according to the original support force method.
[0036] The template support assembly includes a main beam 3 and a secondary beam 4. The main beam 3 is detachably connected to the top support 14. The main beam 3 is arranged laterally along the pipe gallery, and several main beams 3 are arranged at intervals along the axial direction of the pipe gallery. The secondary beam 4 is detachably connected to the top of the main beam 3. The secondary beam 4 is arranged along the axial direction of the pipe gallery, and several secondary beams 4 are arranged at intervals along the transverse direction of the pipe gallery. The secondary beam 4 is used to support the template 5.
[0037] In some specific implementation methods, such as Figure 6 and Figure 7 As shown, the main beam 3 includes two channel steels 31 with opposite openings and a gap between them. The ends of the two channel steels 31 are welded together by end plates 32. The top support 14 includes a U-shaped portion, and the main beam 3 is disposed in the groove of the U-shaped portion. The main beam 3 is detachably connected to the U-shaped portion by a second fastener 33. The second fastener 33 includes a pressure plate, a second screw, a washer, and a nut. The bottom of the U-shaped portion has a through hole, and the washer is disposed at the bottom of the through hole. The pressure plate presses against the tops of the two channel steels 31. The second screw passes through the pressure plate, the gap, the through hole, and the washer and is locked by the nut. The through hole can be as follows: Figure 6 The slot shown allows the second screw to be inserted through the gap and hook onto the U-shaped base plate, thus facilitating installation.
[0038] In some specific implementation methods, such as Figure 8 and Figure 9 As shown, the secondary beam 4 is detachably connected to the top of the main beam 3 via a third fastener 8. The secondary beam 4 has through grooves 41 running along its length on both sides, and the third fastener 8 extends into these through grooves 41. The third fastener 8 includes two fastener plates; one fastener plate has a slot at its bottom, and the other fastener plate has a tooth at its bottom. The tooth engages with the slot. The top of the fastener plate is bent and can extend into the through groove 41. The side of the fastener plate has a locking groove that engages with the top wall of one of the channel steel 31. One of the fastener plates is locked to the top wall of the channel steel 31 by a third bolt. The secondary beam 4 has two through grooves 41 near its top and bottom, respectively, allowing for installation on both sides of the secondary beam 4.
[0039] This embodiment describes a mobile support system for pipe gallery formwork. The support system is formed by a bracket 1 and is suitable for pipe galleries with small cross-sectional dimensions. Telescopic components allow for height adjustment of the foot supports 12 and top supports 14. Detachable wheels 6 and height-adjustable foot supports 12 enable the bracket 1 to switch between support and mobile modes. After supporting work in one work section is completed, it switches to mobile mode to move to the next work section for support, eliminating the need for complete disassembly, transportation, and reinstallation of the bracket 1. Multi-segment design 11 strengthens the structural strength of the bracket 1, preventing deformation during mode switching. When switching to mobile mode, the support structure 1 is reinforced by the scaffolding pipe 7 to prevent excessive lateral bending moment between the traveling wheels 6 from damaging the support 1. The foot support 12 is supported by the first fastener 15 to prevent the foot support 12 from touching the ground and causing obstruction. The longitudinal and transverse arrangement of the main beam 3 and the secondary beam 4 enables the support 1 to effectively support the template 5. Adjacent supports 1 are connected by connecting rods 2. If the connecting rods 2 are of the same length, the adjacent supports 1 are arranged along the axis of the pipe gallery, which is suitable for the straight section of the pipe gallery. If one side of the connecting rod 2 is longer and the other side of the connecting rod 2 is shorter, the axes of the adjacent supports 1 have an angle, which is suitable for the curved section of the pipe gallery. This mobile support system has a simple structure, is easy to use, and has good effect.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
