Description

Technical Field

[0001] The utility model relates to the technical field of temporary supports, in particular to a support rod system. Background Art

[0002] With the continuous development of the economy and the increasing demand for urban underground space development, the mechanized construction technology of underground space has achieved unprecedented development, and a variety of mechanical tunneling technologies have emerged. The mechanical tunneling method for large-section underground construction projects has also been developed. In the construction of large-section underground projects by tunneling, the structural segmentation method is often adopted. During the excavation process, a temporary steel support structure is set to support the segments to ensure the stability of the main structure. After the entire tunnel is excavated and the permanent beam and column structures are constructed, the temporary steel support structure is removed to complete the force transfer of the main structure section. For example, in the underground parking lot project of China Railway Equipment Group described in the paper "Research on the Structural Segmentation and Conversion Construction Method of Large Underground Spaces", steel pipe segments are used as the temporary support structure. However, in actual construction, due to various load effects, the temporary steel support may still bear the pressure transmitted by the structure during disassembly, making the removal process difficult.

[0003] With the progress of tunneling construction technology, the mechanized construction technology of underground projects has been gradually improved, and research has also been carried out on the temporary support disassembly technology suitable for mechanized construction. For example, a prefabricated rod device for temporarily supporting and reinforcing tunnel structures disclosed in the utility model patent with the application number CN202122862986.1, a cross-section support and protection device for subway construction disclosed in the utility model patent with the application number CN202221578834.7, and a tunnel support structure disclosed in the utility model patent with the application number CN202321098996.5 all use jacks as adjustable supports, which can not only adapt to different cross-section sizes but also avoid the situation where the support is difficult to remove during disassembly. However, they are only applicable to the temporary support of a single independent tunnel and cannot replace the temporary steel support in the structural segmentation and conversion construction method of large underground spaces.

[0004] Another example is a convenient disassembly structure for temporary steel members disclosed in the utility model patent with the application number CN201720508190.7, which can be used for the temporary support of horizontally adjacent divided units in a single-layer underground space. However, during the construction of multi-layer underground spaces, the temporary supports between the upper and lower overlapping divided units are cross-installed, resulting in problems such as the inability to flexibly arrange the support removal sequence and interference with other construction processes.

[0005] Therefore, it is necessary to design a temporary segment support structure suitable for multi-layer and multi-span underground space structures.

[0006] It should be particularly noted that the above technical information is only intended to deepen the understanding of the overall background technology of the present utility model, and should not be regarded as admitting or implying in any form that the above technical information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0007] In view of the deficiencies in the above-mentioned background technology, the utility model proposes a support rod system, which solves the technical problems in the prior art that the support structure cannot be flexibly supported and dismantled and is easy to interfere with other processes.

[0008] The technical solution of this application is:

[0009] A support rod system, including a conversion joint of an integrated polygonal structure or a split polygonal structure, the conversion joint can be L-shaped, triangular, quadrilateral, pentagonal, etc. The integrated polygonal structure is an integrated structure and cannot be disassembled, and the split polygonal structure is a detachable structure. The conversion joint serves as a node structure of the support system, and its main purpose is to convert the support direction or position, and to conveniently disassemble and reorganize the partitions; the conversion joint is connected with at least two support bodies, and the support bodies serve as main force-bearing rods, and the corresponding construction quantity and support direction can be selected according to different support scenes; the conversion joint is detachably connected to the support body through an active joint, and the flexibility and convenience of construction and turnover are improved by the transition connection of the active joint, and a makeshift groove for accommodating a telescopic device is provided on the active joint.

[0010] On the basis of the above technical solution, as a preferred technical solution for the support rod system, the integrated polygonal structure is a regular polygonal structure, and each of the supporting bodies is respectively connected to each side of the regular polygonal structure through the movable joint. The present technical solution provides an optimal shape for the integrated polygonal structure, and the use of a regular polygonal structure can have better force-bearing and force-transmitting performance; for example, when each supporting body needs to be built into a Y-shaped support system, the conversion joint can adopt an equilateral triangle, a regular hexagon, and other structural forms, the purpose of which is to make each supporting body form an equiangular distribution; for another example, when each supporting body needs to be built into a star-shaped support system, the conversion joint can adopt a regular polygon structure with the same number of sides as the number of supporting bodies, or a regular polygon structure with twice the number of supporting bodies, and other structural forms, the purpose of which is also to make each supporting body form an equiangular distribution; for another example, when each supporting body needs to be built into a cross-shaped support system, the conversion joint can adopt a square structure with the same number of sides as the number of supporting bodies, or a regular octagon structure with twice the number of supporting bodies, and other structural forms, the purpose of which is also to make each supporting body form an equiangular distribution.

[0011] On the basis of the above technical solution, as a preferred technical solution of the support rod system, the split polygonal structure is a regular polygonal structure formed by detachably connecting a plurality of adapter components. The difference between this technical solution and the above technical solution lies in the adoption of a split structure, where the adapter components are assembled into adapters corresponding to the requirements. In addition to the same functions as the above technical solution, it has a more flexible and variable effect, further enhancing the flexibility.

[0012] On the basis of the above technical solution, as a preferred technical solution of the support rod system, when the adapter needs to connect the four support bodies above, below, left, and right, the adapter is a regular octagonal structure composed of four adapter components. The four side edges of the regular octagonal structure above, below, left, and right are respectively connected to a support body, and the other side edges of the regular octagon serve as both a strengthening structure and can reserve an operation space for disassembly and assembly.

[0013] On the basis of the above technical solution, as a preferred technical solution of the support rod system, the adapter component includes a vertical back plate and a horizontal bottom plate that are vertically connected to form an L shape. The top end of the vertical back plate is vertically connected to a horizontal top plate parallel to the horizontal bottom plate, and the horizontal bottom plate is vertically connected to a vertical panel parallel to the vertical back plate. Each adapter component is detachably connected through the vertical back plate and the horizontal bottom plate, and the vertical panel and the horizontal top plate are respectively detachably connected to the corresponding movable joints.

[0015] On the basis of the above technical solution, as a preferred technical solution of the support rod system, both the horizontal top plate and the vertical panel are flange plates. The flange plates are connected to the corresponding movable joints through bolt groups, and bolt holes or clamping structures for connecting adjacent adapter components are provided on both the vertical back plate and the horizontal bottom plate.

[0016] On the basis of the above technical solution, as a preferred technical solution of the support rod system, an operation opening for disassembly operation is provided between the vertical panel and the horizontal top plate.

[0017] On the basis of the above technical solution, as a preferred technical solution of the support rod system, the movable joint includes two assembled movable joint components, and a semi-circular said relief groove is provided at the splicing part of the two movable joint components.

[0018] On the basis of the above technical solution, as a preferred technical solution of the support rod system, the telescopic device is a jack or a hydraulic cylinder, and the support main body is a steel support.

[0019] Compared with the prior art, the technical solution provided by the present utility model has the following technical effects:

[0020] This technical solution can not only be used for segment support, but also for the support of other building structures. It can be used not only for temporary support, but also for permanent support. For cross-connected steel supports, a conversion joint is provided between adjacent steel supports, and the originally overlapping steel supports are respectively connected to the conversion joint through movable joints, making the steel supports independent of each other and not affecting each other during demolition, increasing the flexibility of the demolition sequence, avoiding the interference of the steel supports on the construction of the internal main structure, and the design of the movable joint improves the easy-disassembly property of the steel support, which is beneficial to improving construction efficiency and safety. In addition, the support structure can be reused repeatedly, reducing the amortization cost and effectively improving economic benefits. Description of the Drawings

It should also be understood that terms defined in a general dictionary, such as, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0048] Techniques, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the specification.

[0049] A support rod system, such as Figure 1 、 Figure 2 、 Figure 15 、 Figure 16 and Figure 17As shown in the figure, it includes an adapter 1 which can be an integral polygonal structure or a split polygonal structure. The adapter 1 can be L-shaped, triangular, quadrilateral, pentagonal, etc. The integral polygonal structure is an integral structure that cannot be disassembled, and the split polygonal structure is a disassemblable structure. The adapter 1 serves as the node structure of the support system, and its main purpose is to support the conversion of direction or position, as well as to facilitate disassembly and recombination in different zones.

[0050] At least two support bodies 3 are connected to the adapter 1. The support bodies 3 are the main load-bearing members, and the corresponding number of supports and support directions can be selected according to different support scenarios. The adapter 1 and the support body are detachably connected through the movable joint 2. The flexible connection through the movable joint 2 improves the flexibility and convenience of erection and turnover. A relief groove 2-2 for placing the telescopic device 4 is provided on the movable joint 2. When the support rod system is erected and disassembled, the corresponding support body 3 can be conveniently added and removed through the telescopic device 4.

[0051] That is, the purpose of the utility model is to provide a support structure that can be flexibly disassembled, which can be used not only to support the segment but also to support other building structures.

[0052] To achieve the above purpose, this embodiment includes: a support body 3; a movable joint 2, which is divided into two left and right movable joint components 2-1 for connecting the support body 3 and the adapter 1. A notch is provided on the connecting surface of the two movable joint components 2-1 to facilitate the jack to pass through the notch after combination and support on the structures of the support body 3 and the adapter 1; an adapter 1 for connecting adjacent support bodies 3. The adapter 1 can be connected to several support bodies 3 through the movable joint 2 to form a stable closed-loop support structure.

[0053] In the application of supporting the segment, when the support structure is assembled, one side of the support body 3 is connected to the segment structure, and the other side is connected to the movable joint 2. Then the movable joint 2 is connected to the adapter 1. At the same time, the adapter 1 is connected to other cross-connected support bodies 3 in the same way to form a complete support structure. When a local support body 3 is removed, a jack is placed inside the movable joint 2, passed through the notch on the connecting plate, and supported between the removed corresponding support body 3 and the adapter 1 to form an operation space. Then the support body 3 is removed, and the adapter 1 and the support bodies 3 that are not removed temporarily remain in place to complete the support and play a supporting role. After the internal structure construction is completed, the remaining movable joints 2 can be removed, and then the support bodies 3 and the adapter 1 can be removed separately.

[0054] Thus, according to this embodiment, a transition joint 1 is provided between the mutually connected support bodies 3. The originally mutually overlapping steel pipe sections are connected to the transition joint 1 through movable joints, making the support bodies 3 independent of each other and having no influence on each other during the removal of the supports, increasing the flexibility of the removal sequence, and avoiding the influence and interference of the support removal process on the overall structure construction process.

[0055] Based on the above embodiment, as a preferred embodiment of the support rod system, the integral polygonal structure is a regular polygonal structure, and each of the support bodies 3 is respectively connected to each side of the regular polygonal structure through the movable joint 2.

[0056] This embodiment provides a preferred shape of the integral polygonal structure. Adopting a regular polygonal structure can have better force transmission performance. For example, when each support body 3 needs to be built into a Y-shaped support system, the transition joint 1 can adopt an equilateral triangle structure, a regular hexagon structure, etc. Of course, it can also be like Figure 15 shown, adopting a non-equilateral hexagon structure, the purpose of which is to make each support body 3 form an equiangular distribution.

[0057] For another example, when each support body 3 needs to be built into a star-shaped support system, as Figure 17 shown, the transition joint 1 can adopt a regular polygonal structure with the same number of sides as the number of support bodies 3, or a regular polygonal structure with the number of sides twice that of the support bodies 3, etc. The purpose is also to make each support body 3 form an equiangular distribution.

[0058] For another example, when each support body 3 needs to be built into a cross-shaped support system, as Figure 16 shown, the transition joint 1 can adopt a square structure with the same number of sides as the number of support bodies 3, or a regular octagon structure with the number of sides twice that of the support bodies 3, etc. The purpose is also to make each support body 3 form an equiangular distribution.

[0059] Based on the above embodiment, as a preferred embodiment of the support rod system, as Figure 1 and Figure 2 shown, the split polygonal structure is a regular polygonal structure formed by detachably connecting a plurality of transition joint components. The difference between this embodiment and the above embodiment is that a split structure is adopted, and the transition joint 1 is assembled from the transition joint components according to the corresponding requirements. In addition to the same functions as the above embodiment, it has a more flexible and changeable effect, further improving the flexibility.

[0060] Based on the above embodiment, as a preferred embodiment of the support rod system, as Figure 1As shown, when the adapter 1 needs to be connected to the four support bodies 3 above, below, left, and right, the adapter 1 is a regular octagon structure composed of four adapter components. The four side edges of the regular octagon structure above, below, left, and right are respectively connected to a support body 3, and the other side edges of the regular octagon serve as both a strengthening structure and can reserve an operation space for disassembly and assembly.

[0061] Based on the above embodiments, as a preferred embodiment of the support rod system, as Figure 4 shown, the adapter component includes a vertical back plate 1-1 and a horizontal bottom plate 1-2 that are vertically connected to form an L shape. The top end of the vertical back plate 1-1 is vertically connected to a horizontal top plate 1-3 parallel to the horizontal bottom plate 1-2. The horizontal bottom plate 1-2 is vertically connected to a vertical panel 1-4 parallel to the vertical back plate 1-1. Each adapter component is detachably connected through the vertical back plate 1-1 and the horizontal bottom plate 1-2, and the vertical panel 1-4 and the horizontal top plate 1-3 are respectively detachably connected to the corresponding movable joint 2.

[0062] Based on the above embodiments, as a preferred embodiment of the support rod system, as Figure 3 shown, side plates 1-5 connected to the vertical back plate 1-1, the horizontal bottom plate 1-2, the horizontal top plate 1-3, and the vertical panel 1-4 are provided on both sides of the adapter component, and a reinforcing plate 1-6 connected to the vertical back plate 1-1, the horizontal bottom plate 1-2, the horizontal top plate 1-3, and the vertical panel 1-4 is provided between the two side plates 1-5.

[0063] Based on the above embodiments, as a preferred embodiment of the support rod system, as Figure 2 and Figure 4 shown, both the horizontal top plate 1-3 and the vertical panel 1-4 are flange plates. The flange plates are both connected to the corresponding movable joint 2 through bolt groups, and bolt holes or clamping structures for connecting adjacent adapter components are provided on both the vertical back plate 1-1 and the horizontal bottom plate 1-2.

[0064] Based on the above embodiments, as a preferred embodiment of the support rod system, as Figure 4 shown, an operation opening 1-7 for disassembly operation is provided between the vertical panel 1-4 and the horizontal top plate 1-3.

[0065] Based on the above embodiments, as a preferred embodiment of the support rod system, as Figure 6 shown, the movable joint 2 includes two assembled movable joint components 2-1, and a semicircular relief groove 2-2 is provided at the splicing part of the two movable joint components 2-1.

[0066] Based on the above embodiments, as a preferred embodiment of the support rod system, as Figure 5 shown, the telescopic device 4 is a jack or a hydraulic cylinder, and the support main body 3 is a steel support. For the cross-connected steel support structure, a conversion joint is arranged between adjacent steel support main bodies, so that the steel support main bodies are independent of each other and do not affect each other during demolition, increasing the flexibility of the demolition sequence and avoiding the interference of the steel support on the construction of the internal main structure. The temporarily assembled steel support structure that can be disassembled flexibly, the design of the movable joint and the use of the jack improve the disassembly convenience of the steel support, which is beneficial to improving the construction efficiency and safety.

[0067] As a preferred application mode of the present invention, a segment support structure with convenient disassembly and flexible demolition sequence is proposed, which can be widely applied to the mechanical tunneling multi-layer multi-span large-section underground space project. The specific implementation mode is as follows:

[0068] As shown in the attached Figure 1 and attached Figure 2 figures, the conversion joint 1, the movable joint 2 and the steel support main body jointly form a cross steel support structure.

There are bolt holes 1-8 on the flange plates, and the flange plates and the movable joint 2 are connected together through the bolt holes 1-8 to further connect two mutually perpendicular steel support main bodies. Bolt holes are also arranged on the bottom and rear steel plates of the conversion joint 1 for connecting with the corresponding positions of other conversion joints. In addition, side plates are arranged on both sides of the conversion joint 1, reinforcing plates are arranged inside, and operation openings are arranged outside, so as to carry out bolt disassembly operations inside the conversion structure.

[0070] As shown in the attached Figure 5 and attached Figure 6 figures, one end of the movable joint 2 is connected to the conversion joint 1, and the other end is connected to the steel support main body. The movable joint 2 is assembled by two movable joint components 2-1. The position of the middle semi-circular notch is the placement position of the jack 4 during the process of disassembling the steel support. When the steel support needs to be removed, the jack 4 is placed in the movable joint 2, propped against the steel support main body and the conversion joint 1, replacing the movable joint 2 to bear the pressure. Then, the movable joint components 2-1 are respectively pulled out, the jack 4 is loosened and taken out to form an operation space, and finally the steel support main body is removed.
