Description

Technical Field

[0001] The present invention belongs to the field of foundation pit support structures, and specifically relates to a permanent and temporary dry-jointed self-sensing support plate structure and a permanent and temporary integrated full dry-jointed support structure. Background Art

[0002] The rapid development of my country's economy in this century has greatly promoted urbanization and the growth of urban population, leading to increasing shortage of urban land. In order to effectively improve the land utilization rate of cities, underground shopping malls, underground garages, underground rail transit, civil air defense projects and other underground facilities are increasing in major cities, prompting the development of underground projects in full swing.

[0003] Regardless of whether the underground project adopts the open-cut method, covered-cut method or dark-cut method, it is necessary to construct the supporting structure in advance. The purpose is to achieve the support of soil pressure and water pressure. At the same time, in order to prevent landslides, it is necessary to carry out earth excavation while constructing the internal supporting structure. However, with the increasing depth of foundation pit excavation, the supporting structure required to maintain the safety of foundation pit construction has become more and more complex. The existing supporting structure often requires cast-in-place concrete, and the force transmission of its wet joints is affected by many factors such as maintenance conditions, material differences, and manual operation, which poses a huge challenge to the construction safety risk.

[0004] Therefore, in recent projects, the call for a permanent and temporary integrated support-main structure has intensified. In all support structures, the support plate plays a supporting role for the ground-connected walls on both sides of the support system. However, the existing support plates still have the following problems: 1) Since the nodes are cast in situ, the degree of support effect of the support plate is greatly affected by factors of on-site construction, such as the concrete filling degree of the cast-in-situ nodes, the concrete bearing capacity, etc., and its consistency and accuracy are difficult to guarantee; 2) Since the nodes are cast in situ, it is unclear whether the support plate is load-bearing and the force transmission performance of the cast-in-situ nodes. This uncertainty brings great risks to the project. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a permanent and temporary integrated all-dry-jointed support structure and a construction method thereof which can ensure construction safety and do not increase construction difficulty.

[0006] The content of the present invention includes a self-sensing support plate structure for permanent and temporary dry-joining, including a purlin, a longitudinal beam, a support plate and a self-sensing system; one end of the support plate is installed on the purlin, and the other end is installed on the longitudinal beam; the self-sensing system includes a line docking structure and an indication device, and the line docking structure is arranged on the support plate and the purlin and / or the longitudinal beam. After the support plate and the purlin are installed in place and / or the support plate and the longitudinal beam are installed in place, the line docking structure is successfully docked, and the indication device indicates that the docking is successful.

[0007] The beneficial effect of the present invention is that the self-sensing support plate structure for permanent and temporary dry splicing provided by the present invention can display the installation of the support plate and whether the purlin and / or longitudinal beam are installed in place after the support plate is installed by setting a self-sensing system, and can fully monitor the stress state of the support plate (if it is installed in place, the stress state is good, otherwise the stress state is poor), ensuring that its structural force transmission is good. In addition, by using all prefabricated structures as support structures and performing non-cast-in-situ dry splicing on site, the force system transmission of the entire support structure is clear, and the self-sensing system can further ensure clear force system transmission, clarify the uncertainty of support plate force transmission during construction, and reduce engineering risks. The safety risks of structural differences and construction contingencies due to cast-in-situ concrete are greatly reduced. In addition, in the permanent and temporary integrated support plates, dry splicing nodes are used instead of cast-in-situ nodes, and the assembly process is used instead of the cast-in-situ concrete process, so as to solve the construction errors caused by factors such as construction quality and make the construction process more standardized and clear.

[0011] As attached Figure 1 -Attached Fig.29As shown, the present invention provides a permanent and temporary integrated dry-jointed supporting structure, comprising a ground-connected wall 1, a purlin assembly 2, a longitudinal beam and column assembly 3 and a plurality of support plates 4, wherein the ground-connected wall 1 and the purlin assembly 2 are symmetrically arranged in two groups, preferably, the two groups of ground-connected walls 1 and the purlin assembly 2 are arranged in a mirror-symmetrical manner, and the longitudinal beam and column assembly 3 and the plurality of support plates 4 are arranged between the two groups of ground-connected walls 1, wherein the ground-connected wall 1 is used to support both sides of the excavated foundation pit to prevent earth collapse on both sides of the foundation pit, and to achieve support for earth pressure and water pressure, and at the same time, after the foundation pit is excavated, it can be used to provide a template for side concrete pouring, and the support plate 4, on the one hand, longitudinally supports the two ground-connected walls 1 to prevent the two ground-connected walls 1 from being overturned by the pressure of the earth on both sides of the foundation pit, and on the other hand, is used as a template when pouring the concrete bottom surface, and the longitudinal beam and column assembly 3 is used to provide support for the support plate 4 in the middle position of the foundation pit, and at the same time, is used as an inner mold and provides support for the pouring of the middle concrete column; Reference Figure 4 and attached Figure 5 The purlin assembly 2 includes at least two purlins 201 arranged from top to bottom. The number of purlins 201 is determined according to the depth of the foundation pit and the number of layers of the horizontal slab. A plurality of vertical purlins 202 are arranged horizontally (along the length direction of the purlin 201) between every two purlins 201. Reference Figure 1 The longitudinal beam and column assembly 3 includes at least two longitudinal beams 301 arranged from top to bottom, the number of the longitudinal beams 301 is consistent with the number of the purlins 201, and the longitudinal beams 301 and the purlins 201 correspond to each other in the longitudinal direction. Fig.15 The longitudinal beam and column assembly 3 also includes a plurality of columns 302 connecting the plurality of longitudinal beams 301, and the plurality of columns 302 are arranged at intervals along the length direction of the purlin 201. Figure 5 The longitudinal beam 301 is used to support and fix the support plate 4 for forming a horizontal plate surface, and the column 302 is used to support and fix the longitudinal beam 301. Figure 4 , the column 302 is also used to support and fix the vertically arranged support plate 4 used to form a temporary vertical support; A plurality of vertical block purlins 202 correspond to a plurality of columns 302 in the length direction of the purlin 201, and then a support plate 4 can be set up to form a temporary vertical support; Reference Figure 5 The support plate 4 is used to form a horizontal plate surface between the purlin 201 and the longitudinal beam 301 when pouring concrete on the plane. At this time, after the construction process of the full dry support structure is completed, when the concrete pouring process is carried out, the support plate 4 is laid on the plane part between the purlin 201 and the longitudinal beam 301 to form a horizontal plate surface, and then support the horizontal concrete on the non-bottom surface (the bottom surface of the concrete is directly poured on the bottom of the foundation pit) in the pouring foundation pit. Figure 4The support plate 4 is also used to be detachably erected between the vertical block purlin 202 and the column 302 to form a temporary vertical support during the construction process. That is, during the construction process of the full dry-assembled supporting structure, the support plate 4 is also used to provide a vertical support in the range between the two longitudinal purlins 201 and the longitudinal beam 301 through the support plate 4, providing support for the longitudinal interval between the two purlins 201, greatly improving the overall construction stability and reliability in the construction process of the full dry-assembled supporting structure, and improving safety. At the same time, the temporary vertical support can maintain the construction process of the entire full dry-assembled supporting structure, and during the concrete pouring process, the support plates 4 used as temporary vertical supports are removed one by one according to the concrete pouring progress, and the support stability of the full dry-assembled supporting structure is continuously guaranteed during the concrete pouring process, and it is not removed until the temporary vertical support position needs to be poured, so as to make full use of it, and after removal, it can be immediately used as a spare supplementary plate for the support plate 4 above for building the horizontal plate surface, which can replace or reduce the number of support plates 4 transported from above the foundation pit for building the horizontal plate surface, greatly improving the utilization value of the support plate 4, simplifying the construction difficulty, and improving the construction efficiency.

[0012] That is, the present invention adds a component of the vertical block purlin 202, so that the support plate 4 and the column 302 have a new function of building a temporary vertical support in addition to their original functions. The temporary vertical support can improve the support stability and safety of the entire process of the construction process of the full dry-jointed support structure and the concrete pouring process, and it is only disassembled when the temporary vertical support position is finally needed to be poured. After disassembly, it is directly used as a spare plate for the support plate 4 for building the horizontal plate surface, reducing the number of times the support plate 4 is transported from the top of the foundation pit, greatly simplifying the construction difficulty and improving the construction efficiency. In addition, all prefabricated structures can be used as support structures, and non-cast-in-place dry splicing can be performed on site to achieve the purpose of shortening the construction period of underground projects. Through the style design of temporary load-bearing components and main structure components, after the temporary load-bearing components complete the support function, they can be conveniently disassembled and used as main structure components, or they can be further used directly as main structures after concrete pouring, so as to save the cost of underground project construction and avoid pollution to the underground environment.

[0013] In one embodiment, referring to the attached Fig. 9 The vertical block purlin 202 includes a base plate 2021 and a mounting portion 2022, wherein the base plate 2021 is used to be fixed on the ground-connected wall 1 or the two purlins 201. During the concrete pouring process, the vertical block purlin 202 can be disassembled or retained on the ground-connected wall 1 to form an integral body with the concrete pouring. Preferably, the vertical block purlin 202 is disassembled for reuse; wherein the mounting portion 2022 is used for detachably mounting the support plate 4; Reference Figure 3 and attached Figure 4One end of the support plate 4 is detachably connected to the mounting portion 2022, and the other end is detachably connected to the column 302, thereby realizing the construction and disassembly of temporary vertical support, and the support plate 4 is used to support the column 302 and the ground-connected wall 1 to prevent the part of the ground-connected wall 1 here from tipping into the foundation pit.

[0014] In one embodiment, referring to the attached Figure 4 The two ends of the base plate 2021 are respectively against the two purlins 201. This arrangement has two functions. First, the base plate 2021 can position and limit the installation of the two longitudinal purlins 201, simplifying the positioning difficulty of the lower purlin 201 (the purlin 201 is installed from top to bottom), and ensuring the parallelism of multiple purlins 201; second, after the base plate 2021 is installed, since the lower purlin 201 is fixed to the bottom of the foundation pit (the foundation pit is only dug at this time), the base plate 2021 can be used to position and limit the installation of the two longitudinal purlins 201, simplifying the positioning difficulty of the lower purlin 201 (the purlin 201 is installed from top to bottom in sequence .... To the top of the lower purlin 201), the lower purlin 201 is supported by the ground and has good support stability. At this time, the upper purlin 201 can be supported by itself and the fixed structure of the ground-connected wall 1, and is also supported on the lower purlin 201 through the base plate 2021, which can greatly ensure the support stability of the two adjacent purlins 201, improve the bearing stability of the upper purlin 201 and its support plate 4 in the construction process of the full dry-jointed support structure, and comprehensively improve the safety performance. In addition, the multiple base plates 2021 of the multiple vertical block purlins 202 arranged along the length direction of the purlin 201 can ensure the overall support stability of the upper purlin 201 in the length direction.

[0015] In one embodiment, the base plate 2021 is connected to the ground-connected wall 1, that is, the base plate 2021 is fixed or detachably fixed to the ground-connected wall 1, so that the gravity of the upper purlin 201 can not only be partially supported by the lower purlin 201, but also partially transferred to the ground-connected wall 1, further improving the support stability of the upper purlin 201 and its support plate 4. Preferably, the base plate 2021 and the ground-connected wall 1 are detachably matched, that is, the base plate 2021 and the ground-connected wall 1 are correspondingly provided with a detachable overlap structure. Preferably, refer to the attached Fig. 9 and attached Fig.10 The detachable overlapping structure includes a vertical purlin socket 20211 arranged on one side of the base plate 2021 and a vertical block purlin interface 1013 arranged on the ground-connected wall 1. The vertical purlin socket 20211 is inserted into the vertical block purlin interface 1013 to realize the detachable fixation of the base plate 2021 and the ground-connected wall 1.

[0016] Reference Figure 1In one embodiment, the ground-connected wall 1 is formed by horizontally splicing a plurality of wall panels 101. Preferably, each wall panel 101 is provided with an engaging groove 1011 on both sides, and two adjacent wall panels 101 are engaged with each other through the engaging groove 1011, thereby realizing the longitudinal connection between the wall panels 101. Such an arrangement can simplify the installation difficulty of the ground-connected wall 1, reduce the difficulty of hoisting and inserting the ground-connected wall 1 into the ground, thereby simplifying the construction difficulty and improving the construction efficiency. Each of the wall panels 101 is longitudinally provided with a plurality of splicing interfaces 1012, and the splicing interfaces 1012 are used to install the purlin 201; refer to the attached Figure 1 , Attachment Figure 6 and attached Fig.10 The purlin 201 is provided with a plurality of splicing joints 2011 along the length direction, and the plurality of splicing joints 2011 are spliced ​​one by one with the splicing interfaces 1012 on the same horizontal line of each wall panel 101, so that the purlin 201 is fixed to the ground-connected wall 1, and the lateral mutual fixation of the plurality of wall panels 101 is realized. The cooperation of the engaging groove 1011 and the purlin 201 realizes the lateral and longitudinal limitation of the plurality of wall panels 101, so that they form an integral ground-connected wall 1, and improve its supporting effect on the side of the foundation pit. The splicing joints 2011 and the splicing interfaces 1012 on the purlin 201 and the wall panels 101, while realizing the fixing of the purlin 201 to the ground-connected wall 1, realize the fixing of the plurality of wall panels 101 of the ground-connected wall 1, and realize the effect of completing two purposes in one step.

[0017] In one embodiment, referring to the attached Figure 8 , a support groove 401 is provided on one side of the support plate 4, and a clamping structure 402 is provided on the other side; Figure 1 The longitudinal beam 301 or the purlin 201 is provided with a support slide 5, and the support slide groove 401 of the support plate 4 is rotatably engaged with the support slide 5; refer to the attached Figure 7 and attached Fig.12 The purlin 201 or the longitudinal beam 301 is provided with a lap groove 6, Figure 6 In the embodiment, the overlap groove 6 is arranged on the purlin 201. Figure 7In the embodiment, the lap groove 6 is arranged on the longitudinal beam 301, and a plurality of snap-fitting structures 7 are arranged at intervals on the groove surface of the lap groove 6 along the length direction. The support plate 4 is provided with a side of the snap-fitting structure 402 which is overlapped on the lap groove 6, and the snap-fitting structure 402 of the support plate 4 is snapped with the snap-fitting structure 7. The snap-fitting structure 402 and the snap-fitting structure 7 can also adopt other snap-fitting devices such as pins and holes, buckles and slots, bolts and screw holes, etc., and are not specifically limited. Preferably, the snap-fitting structure 402 and the snap-fitting structure 7 adopt the cooperation of limiting grooves and limiting protrusions to improve the limiting effect. Preferably, a limiting groove is arranged on the snap-fitting structure 402, and a limiting protrusion is arranged on the snap-fitting structure 7. After the limiting protrusion is embedded in the limiting groove, the support plate 4 and the lap groove 6 are limitedly engaged. That is, when the supporting slide 5 is arranged on the longitudinal beam 301 , the overlapping groove 6 and the snap-fitting structure 7 are arranged on the purlin 201 ; conversely, when the supporting slide 5 is arranged on the purlin 201 , the overlapping groove 6 and the snap-fitting structure 7 are arranged on the longitudinal beam 301 .

[0018] In this embodiment, the installation of the support plate 4 to the longitudinal beam 301 and the surrounding purlin 201 is divided into two steps. The first step is to refer to the attached Figure 1 , Attachment Figure 2 and attached Fig. 27 First, slide the support slide 401 into the support slide 5 at a small angle; second, refer to the attached Figure 3 The upper middle part is used as the support plate of the horizontal plate surface 4, attached Fig.28 The end of the clamping structure 402 of the support plate 4 can be rotated downward with the supporting slide groove 401 as the center of the circle, so that the end of the clamping structure 402 of the support plate 4 is overlapped in the overlap groove 6, and the overlap groove 6 supports and rotates the end of the support plate 4. At the same time, the clamping structure 402 on the support plate 4 cooperates with the clamping matching structure 7 in the overlap groove 6 to achieve the horizontal limitation of the support plate 4 in all directions, the cooperation between the support slide groove 401 and the support slide 5, the cooperation between the support plate 4 and the overlap groove 6, and the clamping structure 402 on the support plate 4 The three cooperations of the connection structure 402 and the snap-fit ​​structure 7 form a good support and limit for the support plate 4. When disassembling (the support plate 4 used as a horizontal plate surface is generally not disassembled), only the reverse operation is required, that is, the first step is to rotate the support plate 4 upward with the support slide 401 as the center of the circle, so that the support plate 4 and the overlap groove 6 are separated, and the snap-fit ​​structure 402 and the snap-fit ​​structure 7 are separated; the second step is to pull out the support slide 401 from the support slide 5 at a small angle. Since the support plate 4 always bears the downward force, it has a good downward force support effect after the support plate 4 is installed, and the disassembly requires an upward force. Therefore, when there is no external force for disassembly, the fixation of the support plate 4 is stable and reliable, and safety can be guaranteed.

[0019] In one embodiment, referring to the attached Fig. 9The vertical block purlin 202 includes a base plate 2021, a mounting portion 2022 and a limit plate 2023; the mounting portion 2022 includes a vertically arranged support slide 5, the limit plate 2023 is arranged at the bottom of the support slide 5, the limit plate 2023 is used to limit the longitudinal height of the support plate 4 as a temporary vertical support, and the support slide groove 401 of the support plate 4 is rotatably engaged with the support slide 5; the column 302 is provided with a vertical overlap block 3021 on the side facing the vertical block purlin 202, and one side of the clamping structure 402 of the support plate 4 is overlapped on the vertical overlap block 3021.

[0020] In this embodiment, the installation and disassembly steps of the support plate 4 used as a temporary vertical support are similar to those of the support plate 4 used as a horizontal plate surface. Specifically, the installation of the support plate 4 to the vertical block purlin 202 and the column 302 is divided into two steps. The first step is to first slide the support slide groove 401 into the vertically arranged support slide 5 at a small angle; the second step is that the end of the clamping structure 402 of the support plate 4 can be rotated inward with the support slide groove 401 as the center of the circle, so that the end of the clamping structure 402 of the support plate 4 is located above the vertical lap block 3021; ​​the third step is to move the support plate 4 downward so that one end of the support plate 4 abuts against the limiting plate 2023, and the other end abuts against the vertical lap block 3021, so as to realize the vertical support and limitation of the support plate 4, and the setting of the limiting plate 2023 can make the support plate 4 exactly in the middle position of the two purlins 201, thereby optimizing the force distribution of the temporary vertical support. When disassembling (the support plate 4 used as a temporary vertical support needs to be disassembled), there are two steps in total, namely, the first step is to rotate the support plate 4 outward with the support groove 401 as the center of the circle, so that the support plate 4 and the vertical overlap block 3021 are separated; the second step is to pull out the support groove 401 from the support slide 5 at a small angle.
