Description

Technical Field

[0001] The invention relates to the field of subway stations, and in particular to an assembled lattice column assembly for subway station construction. Background Art

[0002] Modern subway stations are basically built in underground tunnels and are underground stations. Subway stations are composed of platform floors, station hall floors, equipment floors, and entrances and exits. Lattice columns are mostly used in the construction process. The lattice columns of subway stations play a role in supporting and stabilizing the structure during construction.

[0003] The lattice columns used in the construction of existing subway stations are mostly integrated. After the subsequent construction is completed, the staff needs to dismantle the lattice columns. In the process of dismantling the lattice columns of the subway station, since the lattice columns are a whole, a plasma cutting machine is usually required for cutting. The specific cutting part of the lattice columns of the subway station needs to be determined according to the design plan and the actual situation on site. Usually, the cutting part includes the following main parts: node connection parts, connection points between columns and foundations, connection points of horizontal supports, etc. This cutting process requires a lot of time, materials and labor, and there are certain safety risks in the dismantling process. At the same time, the cut lattice columns are difficult to reuse, which will cause a large waste of materials.

[0004] In summary, the above-mentioned lattice columns are difficult to reuse in actual use, resulting in a large waste of materials. At the same time, the workers need to spend a lot of time, materials and labor in the process of dismantling them, and there are certain safety risks in the process of dismantling. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a prefabricated lattice column assembly for subway station construction, so as to solve the technical problems that the lattice columns are difficult to reuse during actual use, resulting in a large waste of materials, while excessive manpower and material resources are wasted during cutting, and there are certain safety risks during the dismantling process.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an assembled lattice column assembly for subway station construction, comprising a first lattice column section and a second lattice column section, the tops of the first lattice column section and the second lattice column section are both provided with angle steels, and the bottom of the second lattice column section is provided with a mounting column clamped with the angle steel, a joining plate is detachably provided at the connection between the first lattice column section and the second lattice column section, a bolt assembly is penetrated through the outer wall of the joining plate, fixing holes for the bolt assembly to penetrate are provided on the joining plate, the angle steel and the mounting column, a first enclosure is detachably provided on the top of the outer wall of the second lattice column section, and a second enclosure is slidably provided on the first enclosure, and the first enclosure and the second enclosure are located between concrete floor slabs.

[0007] By adopting the above technical scheme, the first lattice column segment and the second lattice column segment are spliced ​​together through the cooperation of the angle steel and the installation column, which further ensures the stability between the first lattice column segment and the second lattice column segment. There is no need to cut them into sections during subsequent disassembly, which reduces the overall disassembly risk and ensures that the first lattice column segment and the second lattice column segment can be reused many times. The subsequent staff will cut the floor slab, and then crush the concrete at the connection between the first enclosure and the second enclosure, and disassemble the two sets of enclosures. During this process, the outer walls of the first lattice column segment and the second lattice column segment will not solidify concrete, which is convenient for the subsequent staff to reuse the first lattice column segment and the second lattice column segment.

[0008] The present invention is further configured as follows: a top rod is slidably arranged in the installation column, and a top plate is connected to the installation column at the top end of the top rod, a fixed plate is welded at the top of the top plate in the second lattice column section, a sliding plate is slidably arranged in the fixed plate, and an array of guide columns is arranged at the top of the sliding plate, a slot is opened in the fixed plate, and a plug plate matching the slot is connected to the bottom of the first enclosure plate, and a socket corresponding to the guide column is penetrated on the plug plate.

[0009] By adopting the above technical solution, the staff inserts the plug plate on the first enclosure into the slot of the fixed plate, and then combines and splices the first enclosure with the second enclosure through the cooperation of the T-block and the T-slot. At the same time, after the second lattice column section is connected to the first lattice column section through the bolt assembly, the top rod in the installation column will be pushed up. At this time, the top rod drives the top plate to be inserted into the top of the fixed plate, and the sliding plate drives the guide column to slide upward under the action of the top plate. Since an array of sockets for the guide column to be inserted is provided on the plug plate, the first enclosure is limited by the action of the guide column and the socket, thereby ensuring the stability of the first enclosure and the second enclosure in the second lattice column section, and preventing the first enclosure and the second enclosure from being offset during the construction process.

[0010] The present invention is further configured such that the angle steel extends out of the tops of the first lattice column section and the second lattice column section, and the mounting column extends out of the bottom of the second lattice column section.

[0011] By adopting the above technical solution, the installation column will cooperate with the angle steel during the actual splicing process, so that the overall force on the top end of the first lattice column section and the bottom end of the second lattice column section is more uniform, further improving the overall stability of the structure.

[0012] The present invention is further configured such that the bolt assembly includes a fixing column, a nut and a screw rod, both ends of the fixing column are connected to the screw rod, and a nut is slidably provided on the outer wall of the screw rod.

[0013] By adopting the above technical solution, when it is installed in a limited position, the fixing column passes through the fixing holes on the gusset plate, the angle steel and the installation column, so that the screw rod is located on the inner and outer sides of the lattice column, and then it is locked under the action of the nut.

[0014] The present invention is further configured such that the connection between the fixing plate and the inner wall of the second lattice column section is sealed.

[0015] By adopting the above technical solution, in the subsequent process of pouring concrete for the floor slab, when the concrete passes through the first enclosure and the second enclosure, the concrete is prevented from falling to the first lattice column section at the bottom, thereby further improving the efficiency of the overall construction.

[0016] The present invention is further configured such that a T-shaped groove is diagonally provided on the inner wall of the second enclosure, and T-shaped blocks matching with the first enclosure are provided at both ends of the first enclosure, and the top end of the T-shaped groove does not penetrate the second enclosure.

[0017] By adopting the above technical solution, the tightness of the connection between the first enclosure panel and the second enclosure panel is ensured by the cooperation of the T-shaped groove and the T-shaped block. At the same time, the top end of the T-shaped groove does not penetrate the second enclosure panel, thereby preventing the concrete from penetrating into the interior of the first enclosure panel and the second enclosure panel through the top during the pouring process, thereby further improving the sealing during the construction process.

[0018] The present invention is further configured such that the bottom end of the push rod coincides with the outer wall of the fixing column.

[0019] By adopting the above technical solution, when the push rod is supported by the fixing column of the bolt assembly, the push rod itself can be prevented from tilting.

[0020] The present invention is further configured such that an inner groove is provided at the bottom of the slot in the fixing plate, and a limiting mechanism cooperating with the sliding plate is provided in the inner groove.

[0021] By adopting the above technical solution, the sliding plate is located in its inner groove. When the top plate lifts the sliding plate upward, the limiting mechanism in the inner groove can ensure that the sliding plate is located in the inner groove and slides in the vertical direction.

[0022] The present invention is further configured such that the connecting end of the first lattice column segment and the second lattice column segment is configured to be flat.

[0023] By adopting the above technical solution, the flat setting ensures that the first lattice column section is in a vertical state when connected with the second lattice column section, preventing the lattice column from being tilted after assembly, and further improving the stability of the overall support of the lattice column.

[0024] The present invention is further configured such that outer walls of the first lattice column segment and the second lattice column segment are provided with grooves for the attachment plates to be inserted into.

[0025] By adopting the above technical solution, the arrangement of the grooves makes it easy to install the array of panels on the outer walls of the first lattice column section and the second lattice column section respectively, while stabilizing the joint between the two to prevent them from being misaligned.

[0026] In summary, the present invention mainly has the following beneficial effects:

[0027] The present invention improves the stability of the connection between the first lattice column section and the second lattice column section by clamping the fixing plate at the connection between the first lattice column section and the second lattice column section and fixing it in a limited position under the action of the bolt assembly, wherein the angle steel and the mounting column respectively extend from the first lattice column section and the second lattice column section, and the first lattice column section and the second lattice column section are spliced ​​by the cooperation of the angle steel and the mounting column, and the angle steel and the mounting column are both provided with fixing holes for the bolt assembly to penetrate, and this connection method further ensures the stability between the first lattice column section and the second lattice column section, and there is no need to cut them into sections during subsequent disassembly, thereby reducing the overall disassembly risk, and ensuring that the first lattice column section and the second lattice column section can be reused multiple times, thereby reducing the overall construction cost;

[0028] The present invention welds a fixing plate at the bottom end of the second lattice column section, and the fixing plate ensures the stability of the bottom of the second lattice column section to prevent the steel plate at the bottom end from being deformed. At the same time, the outer wall of the second lattice column section is detachably provided with a panel, and the panel is located between concrete floor slabs. During subsequent disassembly, only the concrete at the panel needs to be cut, and then the staff can use a breaker to break the concrete at the connection, so that the disassembly of the panel can be completed quickly. In this process, the outer walls of the first lattice column section and the second lattice column section will not solidify concrete, thereby reducing the subsequent cleaning burden of the staff.

[0029] The present invention provides a slot on the fixed plate and an insert plate on the first enclosure. By inserting the insert plate into the slot in the fixed plate, after the second lattice column section is connected to the first lattice column section by a bolt assembly, the top rod in the mounting column will be pushed up. At this time, the top rod drives the top plate to be inserted into the top of the fixed plate. The sliding plate drives the guide column to slide upward under the action of the top plate. Since an array of insertion holes for the guide column to be inserted into is provided on the insert plate, the first enclosure is limited under the action of the guide column and the insertion hole, thereby ensuring the stability of the first enclosure and the second enclosure in the second lattice column section, and preventing the first enclosure and the second enclosure from being offset during the construction process.

[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] The following describes an embodiment of the present invention based on its overall structure.

[0042] Embodiment 1

[0043] An assembled lattice column assembly for subway station construction, such as Figure 1-Figure 9As shown, it includes a first lattice column segment 1, a second lattice column segment 2, an angle steel 3, a clamping mechanism, a sealing mechanism and a limiting mechanism. An angle steel 3 is provided at the top of the first lattice column segment 1 and the second lattice column segment 2, and a mounting column 8 clamped with the angle steel 3 is provided at the bottom of the second lattice column segment 2, wherein the angle steel 3 extends out of the top of the first lattice column segment 1 and the second lattice column segment 2, and the mounting column 8 extends out of the bottom of the second lattice column segment 2. In the actual splicing process, the mounting column 8 will cooperate with the angle steel 3, so that the overall force on the top end of the first lattice column segment 1 and the bottom end of the second lattice column segment 2 is more uniform, further improving the overall stability of the structure, and the outer walls of the first lattice column segment 1 and the second lattice column segment 2 are provided with grooves for the gusset plate 20 to be clamped, and the setting of the groove It is convenient to install the array of gusset plates 20 on the outer walls of the first lattice column segment 1 and the second lattice column segment 2 respectively, and at the same time, it plays a role in stabilizing the splicing of the connection between the two to prevent them from being misplaced. At the same time, a gusset plate 20 is detachably provided at the connection between the first lattice column segment 1 and the second lattice column segment 2, wherein a bolt assembly 7 is penetrated through the outer wall of the gusset plate 20, and fixing holes 9 for the bolt assembly 7 to penetrate are provided on the gusset plate 20, the angle steel 3 and the installation column 8. This connection method further ensures the stability between the first lattice column segment 1 and the second lattice column segment 2, and there is no need to cut them into sections during subsequent disassembly, thereby reducing the overall disassembly risk, and ensuring that the first lattice column segment 1 and the second lattice column segment 2 can be reused many times, thereby reducing the overall construction cost;

[0044] At the same time, a fixing plate 6 is welded in the second lattice column section 2, and the stability of the bottom of the second lattice column section 2 is ensured by the action of the fixing plate 6, so as to prevent the steel plate at the bottom from being deformed, and a first enclosure 4 is detachably provided on the top of the outer wall of the second lattice column section 2, and a second enclosure 5 is slidably provided on the first enclosure 4, and at the same time, the connection between the fixing plate 6 and the inner wall of the second lattice column section 2 is sealed, so that in the subsequent process of pouring concrete on the floor slab, when the concrete passes through the first enclosure 4 and the second enclosure 5, the concrete is prevented from pouring into the first lattice column section at the bottom. 1 falls, further improving the efficiency of the overall construction, wherein the first enclosure 4 and the second enclosure 5 are located between the concrete floor slabs, and during subsequent disassembly, only the concrete at the enclosure needs to be cut, and there is no need to damage the first lattice column segment 1 and the second lattice column segment 2 in this process. Subsequently, the staff uses a breaker to break the concrete at the connection between the first enclosure 4 and the second enclosure 5, and the disassembly of the enclosure can be quickly completed. During this process, the outer walls of the first lattice column segment 1 and the second lattice column segment 2 will not solidify the concrete, reducing the subsequent cleaning burden of the staff.

[0045] See also Figure 1 and Figure 2The bolt assembly 7 includes a fixing column, a nut and a screw rod. The screw rods are connected to both ends of the fixing column, and a nut is slidably arranged on the outer wall of the screw rod. When the fixing column is installed in a limited position, the fixing column passes through the fixing hole 9 on the fixing plate 20, the angle steel 3 and the installation column 8, so that the screw rod is located on the inner and outer sides of the lattice column, and then it is locked under the action of the nut.

[0046] See also Figure 5 A T-shaped groove 10 is diagonally arranged on the inner wall of the second enclosure 5, and T-shaped blocks 13 matching therewith are arranged at both ends of the first enclosure 4, and the top end of the T-shaped groove 10 does not penetrate the second enclosure 5. The tightness of the connection between the first enclosure 4 and the second enclosure 5 is ensured by the cooperation of the T-shaped groove 10 and the T-shaped block 13. At the same time, since the top end of the T-shaped groove 10 does not penetrate the second enclosure 5, it is prevented that during the pouring process, concrete penetrates into the first enclosure 4 and the second enclosure 5 through the top, thereby further improving the sealing during the construction process.

[0047] Embodiment 2

[0048] like Figure 6 The illustrated assembled lattice column assembly for subway station construction has an overall structure similar to that of the first embodiment, wherein a top rod 19 is slidably arranged in the installation column 8, and a top plate 18 is connected to the top of the top rod 19 through the installation column. The staff inserts the plug plate 11 on the first enclosure 4 into the slot 16 of the fixed plate 6, and then combines and splices the first enclosure 4 with the second enclosure 5 through the cooperation of the T-shaped block 13 and the T-shaped slot 10. At the same time, after the second lattice column section 2 is connected to the first lattice column section 1 through the bolt assembly 7, the top rod 19 in the installation column 8 will be pushed up. Since a fixed plate 6 is welded at the top of the top plate 18 in the second lattice column section 2, and a sliding plate 15 is slidably arranged in the fixed plate 6, and an array of guide columns 17 are arranged at the top of the sliding plate 15, a slot 16 is opened on the fixed plate 6, and a plug plate 11 cooperating with the slot 16 is connected to the bottom of the first enclosure 4, and a plug hole 12 corresponding to the guide column 17 is penetrated on the plug plate 11;

[0049] At this time, the top rod 19 drives the top plate 18 to be inserted into the inner groove 14 of the fixed plate 6, and the sliding plate 15 drives the guide column 17 to slide upward under the action of the top plate 18. Since an array of insertion holes 12 for the guide column 17 to be inserted is provided on the plug plate 11, the first enclosure 4 is limited under the action of the guide column 17 and the insertion hole 12, thereby ensuring the stability of the first enclosure 4 and the second enclosure 5 in the second lattice column section 2, preventing the first enclosure 4 and the second enclosure 5 from being offset in the construction process, and subsequently completing the construction of the first lattice column section During the disassembly of the first and second lattice column sections 1 and 2, after the concrete floor is cut, the bolt assembly 7 is loosened and pulled out of the gusset plate 20, the angle steel 3 and the mounting column 8, and then the top plate 18 is driven to slide downward under the action of the top rod 19's own gravity. At this time, the sliding plate 15 follows and slides to the bottom of the inner groove 14. At this time, the guide column 17 releases the limiting work on the plug plate 11, and then the staff uses a breaker to break the connection between the first enclosure plate 4 and the second enclosure plate 5, so as to realize the removal of the first enclosure plate 4 and the second enclosure plate 5 and speed up the overall construction efficiency.

[0050] See also Figure 6 An inner groove 14 is provided at the bottom of the slot 16 in the fixed plate 6, and a limiting mechanism cooperating with the sliding plate 15 is provided in the inner groove 14. The sliding plate 15 is located in the inner groove 14. When the top plate 18 lifts the sliding plate 15 upward, the limiting mechanism in the inner groove 14 ensures that the sliding plate 15 is located in the inner groove 14 and slides in the vertical direction.

[0051] The working principle of the present invention is as follows: when in use, by plugging the bottom end of the second lattice column segment 2 into the top end of the first lattice column segment 1, the stability of the connection between the first lattice column segment 1 and the second lattice column segment 2 is ensured under the action of the angle steel 3 and the mounting column 8, and at the same time, a detachable gusset plate 20 is provided at the connection between the first lattice column segment 1 and the second lattice column segment 2, wherein the gusset plate 20, the angle steel 3 and the mounting column 8 are all provided with fixing holes 9 for the bolt assembly 7 to penetrate, wherein the bolt assembly 7 will penetrate the gusset plate 20, the angle steel 3 and the mounting column 8 during installation, and this connection method further ensures the stability between the first lattice column segment 1 and the second lattice column segment 2, and ensures that the first lattice column segment and the second lattice column segment can be reused many times, thereby reducing the overall construction cost;

[0052] A fixing plate 6 is welded at the bottom end of the second lattice column section 2. The fixing plate 6 ensures the stability of the bottom of the second lattice column section 2 and prevents the steel plate at the bottom from being deformed. At the same time, a first enclosure 4 is provided at the bottom of the outer wall of the second lattice column section 2, and a second enclosure 5 is slidably provided on one side of the first enclosure 4. During the construction process, the first enclosure 4 and the second enclosure 5 are located between the concrete floor slabs. Subsequent staff will cut the floor slabs, and then crush the concrete at the connection between the first enclosure 4 and the second enclosure 5, and disassemble the two sets of enclosures. During this process, the outer walls of the first lattice column section 1 and the second lattice column section 2 will not solidify concrete, which is convenient for subsequent staff to reuse the first lattice column section 1 and the second lattice column section 2.

[0053] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention.
