Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a triangular steel module structure based on Z-shaped flange connection. Background Technology

[0002] The triangular steel modular structure is an improved form of column-bearing steel modular structure. It is formed by arranging vertical modular units at staggered intervals, with modular units on the same floor arranged across spans, and upper-level modular units arranged above the spaces between them. The gaps are filled by a small number of plate units and column units to form the overall structure. The triangular steel modular structure can avoid the stacked beam and column components and multi-beam and multi-column node construction of traditional column-bearing steel modular structures, reducing the amount of steel used in the structure by about 20%-30%, and improving the assembly performance, overall performance and economic performance of the structure.

[0003] The existing technology for connecting triangular steel modules mostly uses corner joints in traditional column-bearing steel formwork structures. Opening holes in the side walls of the corner joints can weaken the core area of ​​the joint. Furthermore, the staggered overlapping of traditional column-bearing module units can cause uneven indoor height differences, affecting the spatial experience. It is necessary to repair and level the floor height of adjacent modules, which increases the construction process and wastes materials.

[0004] Therefore, there is an urgent need to design a triangular steel module structure based on Z-shaped flange connection to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a triangular steel module structure based on Z-shaped flange connection, which has the advantages of improving installation strength and installation efficiency. It solves the problems in the existing triangular steel module structure based on Z-shaped flange connection, where the opening of the corner fitting side wall easily weakens the core area of ​​the node, and at the same time, it requires leveling the ground height of adjacent modules through decoration, which increases the construction process and wastes materials.

[0006] To achieve the above objectives, the specific technical solution of the present invention for a triangular steel module structure based on a Z-shaped flange connection is as follows:

[0007] A triangular steel module structure based on Z-shaped flange connection includes a first Z-shaped flange and a second Z-shaped flange. The second Z-shaped flange is located below the first Z-shaped flange. Module columns are fixedly connected to both the first and second Z-shaped flanges. The module columns on the second Z-shaped flange are equipped with positioning components that can engage with the module columns on the second Z-shaped flange. The module columns on the first Z-shaped flange are equipped with connecting components. After the first and second Z-shaped flanges are spliced, the connecting components engage with the positioning components, and the positioning components are driven by the connecting components to engage with the module columns on the second Z-shaped flange for pre-installation of the first and second Z-shaped flanges. Subsequently, the pre-installed first and second Z-shaped flanges are fixed with bolts.

[0008] Furthermore, each module column is fixedly connected to two inner partitions, with positioning components installed on its corresponding two inner partitions and connecting components installed between its corresponding two inner partitions.

[0009] Furthermore, the positioning component includes a positioning post, on which a flexible connecting arm and a driving ear are provided. The flexible connecting arm can rotate relative to the positioning post. A contact block is fixedly connected to the flexible connecting arm. The contact block can engage with the inner wall of the module column on the second Z-shaped flange. The driving ear is connected to the flexible connecting arm. When the first Z-shaped flange and the second Z-shaped flange are spliced, the driving ear receives the thrust of the connecting component to drive the flexible connecting arm to rotate until the contact block engages with the inner wall of the module column on the second Z-shaped flange.

[0010] Furthermore, a first annular groove is provided on the positioning post, and a first rotating ring is rotatably connected to the first annular groove. The first rotating ring is fixedly connected to the elastic connecting arm and the driving ear, and the elastic connecting arm and the driving ear rotate around the first rotating ring as the axis.

[0011] Furthermore, a first torsion spring is fitted onto the first annular groove, with its two ends fixedly connected to the inner wall of the first annular groove and the inner wall of the first rotating ring, respectively, so as to provide elastic restoring force to the elastic connecting arm.

[0012] Furthermore, the upper and lower ends of the positioning column are fixedly connected to limit plates, and the inner partitions on the two second Z-shaped flanges are provided with mounting grooves. The positioning column is installed in the mounting grooves, and the two limit plates abut against their corresponding inner partitions.

[0013] Furthermore, the connecting assembly includes a mounting column with an elastic connecting plate that can rotate relative to the mounting column. A stop cylinder is fixedly connected to the elastic connecting plate, and the stop cylinder and the elastic connecting plate can engage with a positioning column. A push column is fixedly connected to the mounting column. When the first Z-shaped flange and the second Z-shaped flange are spliced, the push column applies a thrust to the driving ear, causing the driving ear and the elastic connecting arm to rotate around the first rotating ring as the axis until the contact block engages with the inner wall of the module column on the second Z-shaped flange.

[0014] Furthermore, a second annular groove is provided on the mounting column, and a second rotating ring is rotatably connected to the second annular groove. The second rotating ring is fixedly connected to the elastic connecting plate, and the elastic connecting plate rotates around the second rotating ring as the axis.

[0015] Furthermore, a second torsion spring is fitted onto the second annular groove. The two ends of the second torsion spring are fixedly connected to the inner wall of the second annular groove and the inner wall of the second rotating ring, respectively. The second torsion spring provides an elastic restoring force to the elastic connecting plate.

[0016] Furthermore, each module column is fixedly connected to an H-shaped steel beam, and both the first Z-shaped flange and the second Z-shaped flange are fixedly connected to channel steel beams.

[0017] The present invention has the following advantages:

[0018] (1) This invention improves installation strength and efficiency through two installations, optimizes the structural redundancy and material waste caused by stacked beams and columns in column-bearing steel module structures, and eliminates the need for opening holes in the corner fittings sidewalls, thus not reducing the weakening of the node core area. At the same time, it overcomes the problem of uneven indoor height caused by staggered unit connections, improves the quality of spatial experience, eliminates the need to level the floor height of adjacent modules through decoration, and reduces construction process and material waste.

[0019] (2) The present invention enables the positioning and installation of the first Z-shaped flange and the second Z-shaped flange during installation through the positioning component and the connecting component, thereby facilitating the installation of high-strength bolts on the first Z-shaped flange and the second Z-shaped flange. This eliminates the need to install bolts while positioning the Z-shaped flange during on-site assembly, and also eliminates the need to maintain the stability between the Z-shaped flanges. This reduces the installation difficulty, improves the installation efficiency, and reduces the workload of the workers. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0038] The following is a reference to the appendix. Figure 1 To be continued Figure 11 This invention describes a triangular steel module structure based on a Z-shaped flange connection.

[0039] See Figure 10 , Figure 10 Figure a shows a first rectangular module unit a1 of the prior art. The first rectangular module unit a1 of the prior art, after assembly, is as follows: Figure 10 As shown in b, the assembled first rectangular module unit a1 includes a first single beam position structure b1, a first single column position structure b2, and a first single plate position structure b3, and is combined with Figure 10The enlarged view in section b shows that the existing technology of connecting the triangular steel modules requires the use of corner fittings for the connection nodes of the traditional column-bearing steel formwork structure. The openings on the side walls of the corner fittings can easily weaken the core area of ​​the node, and the staggered connection of the traditional column-bearing module units can cause uneven indoor height differences, affecting the spatial experience.

[0040] Therefore, this Z-shaped steel module structure includes a first Z-shaped flange 1 and a second Z-shaped flange 2. The second Z-shaped flange 2 is located below the first Z-shaped flange 1. Module columns 3 are fixedly connected to both the first Z-shaped flange 1 and the second Z-shaped flange 2. The module columns 3 on the second Z-shaped flange 2 are equipped with positioning components 5, which can engage with the module columns 3 on the second Z-shaped flange 2. The module columns 3 on the first Z-shaped flange 1 are equipped with connecting components 6. After the first Z-shaped flange 1 and the second Z-shaped flange 2 are spliced, the connecting components 6 engage with the positioning components 5, and the positioning components 5 are driven by the connecting components 6 to engage with the module columns 3 on the second Z-shaped flange 2 for pre-installation of the first Z-shaped flange 1 and the second Z-shaped flange 2. Subsequently, the pre-installed first Z-shaped flange 1 and the second Z-shaped flange 2 are fixed with bolts.

[0041] Preferably, the module post 3 on the second Z-shaped flange 2 is provided with a positioning component 5, and the module post 3 on the first Z-shaped flange 1 is provided with a connecting component 6. In other embodiments of the present invention, the module post 3 on the second Z-shaped flange 2 may also be provided with a connecting component 6, and the module post 3 on the first Z-shaped flange 1 may be provided with a positioning component 5. As long as the connecting component 6 and the positioning component 5 can be engaged, and the positioning component 5 is driven by the connecting component 6 to engage with its corresponding module post 3, the first Z-shaped flange 1 and the second Z-shaped flange 2 can be pre-installed.

[0042] Preferably, the first Z-shaped flange 1 and the second Z-shaped flange 2 are welded to the module column 3 by welding. The welding is completed in the factory prefabrication stage to ensure the strength and rigidity of the welded joint. In other embodiments of the present invention, the first Z-shaped flange 1 and the second Z-shaped flange 2 can also be fixed to the module column 3 by other fixing methods.

[0043] After welding, the exposed parts of the first Z-shaped flange 1 and the second Z-shaped flange 2 can be connected, and the bolt connection method facilitates on-site installation and commissioning.

[0044] Each module column 3 is fixedly connected to two inner partitions 4. The positioning component 5 is installed on its corresponding two inner partitions 4, and the connecting component 6 is installed between its corresponding two inner partitions 4. The addition of the inner partitions 4 can improve the overall seismic performance. In other embodiments of the present invention, the module column 3 on the first Z-shaped flange 1 may also be decoupled from the inner partitions 4.

[0045] The positioning component 5 includes a positioning post 501, on which an elastic connecting arm 504 and a driving ear 506 are provided. The elastic connecting arm 504 can rotate relative to the positioning post 501. A contact block 505 is fixedly connected to the elastic connecting arm 504. The contact block 505 can engage with the inner wall of the module post 3 on the second Z-shaped flange 2. The driving ear 506 is connected to the elastic connecting arm 504. When the first Z-shaped flange 1 and the second Z-shaped flange 2 are spliced, the driving ear 506 receives the thrust of the connecting component to drive the elastic connecting arm 504 to rotate until the contact block 505 engages with the inner wall of the module post 3 on the second Z-shaped flange 2.

[0046] Specifically, the contact block 505 is fitted with an anti-slip sleeve. The contact block 505 is engaged with the inner wall of the module column 3 on the second Z-shaped flange 2 by the anti-slip sleeve. The anti-slip sleeve increases friction, prevents slippage, and improves the reliability of engagement.

[0047] Preferably, the positioning post 501 has a first annular groove 502, and a first rotating ring 503 is rotatably connected to the first annular groove 502. The first rotating ring 503 is fixedly connected to the elastic connecting arm 504 and the driving ear 506. The elastic connecting arm 504 and the driving ear 506 rotate about the first rotating ring 503. In other embodiments of the present invention, the elastic connecting arm 504 and the driving ear 506 can also be rotated about the positioning post 501 by other means.

[0048] A first torsion spring 507 is sleeved on the first annular groove 502. The two ends of the first torsion spring 507 are fixedly connected to the inner wall of the first annular groove 502 and the inner wall of the first rotating ring 503, respectively. The first torsion spring 507 provides elastic restoring force to the elastic connecting arm 504.

[0049] When the connecting component 6 pushes the driving ear 506, the first rotating ring 503 rotates, compressing the first torsion spring 507, causing the elastic connecting arm 504 to unfold until the contact block 505 presses against the inner wall of its corresponding module post 3, so as to abut against the inner wall of its corresponding module post 3.

[0050] The upper and lower ends of the positioning column 501 are fixedly connected to the limiting plate 508. The inner partition plate 4 on the two second Z-shaped flanges 2 is provided with the mounting groove 509. The positioning column 501 is installed in the mounting groove 509, and the two limiting plates 508 abut against their corresponding inner partition plates 4 respectively.

[0051] The connecting assembly includes a mounting post 601, on which an elastic connecting plate 604 is provided. The elastic connecting plate 604 can rotate relative to the mounting post 601. An abutting cylinder 606 is fixedly connected to the elastic connecting plate 604. The abutting cylinder 606 and the elastic connecting plate 604 can engage with the positioning post 501. A pushing post 607 is fixedly connected to the mounting post 601. When the first Z-shaped flange 1 and the second Z-shaped flange 2 are spliced, the pushing post 607 applies a pushing force to the driving ear 506, causing the driving ear 506 and the elastic connecting arm 504 to rotate around the first rotating ring 503 as the axis until the contact block 505 engages with the inner wall of the module post 3 on the second Z-shaped flange 2.

[0052] Specifically, the outer side of the abutting cylinder 606 is fitted with an anti-slip sleeve. The abutting cylinder 606 is clamped and engaged with the positioning post 501 by the anti-slip sleeve. The anti-slip sleeve increases friction, prevents slippage, and improves the reliability of engagement.

[0053] Preferably, the mounting post 601 has a second annular groove 602, and a second rotating ring 603 is rotatably connected to the second annular groove 602. The second rotating ring 603 is fixedly connected to the elastic connecting plate 604, and the elastic connecting plate 604 rotates about the second rotating ring 603 as the axis. In other embodiments of the present invention, the elastic connecting plate 604 can also be rotated about the mounting post 601 as the axis by other means.

[0054] Furthermore, a second torsion spring 605 is sleeved on the second annular groove 602. The two ends of the second torsion spring 605 are fixedly connected to the inner wall of the second annular groove 602 and the inner wall of the second rotating ring 603, respectively. The second torsion spring 605 provides elastic restoring force to the elastic connecting plate 604.

[0055] When the first Z-shaped flange 1 and the second Z-shaped flange 2 are spliced, the mounting column 601 moves, and the abutting column 606 contacts the positioning column 501 and is squeezed to open to both sides, compressing the second torsion spring 605; after passing the positioning column 501, the second torsion spring 605 releases its elastic force to reset, causing the elastic connecting plate 604 to close, clamping the positioning column 501, so that the abutting column 606 and the elastic connecting plate 604 are engaged with the positioning column 501, and at the same time, the pushing column 607 squeezes the driving ear 506, triggering the positioning component 5 to engage with its corresponding module column 3.

[0056] Furthermore, each module column 3 is fixedly connected with an H-shaped steel beam 7, and the first Z-shaped flange 1 and the second Z-shaped flange 2 are fixedly connected with channel steel beams 8. Specifically, the H-shaped steel beam 7 and the channel steel beam 8 are at the same height. After the first Z-shaped flange 1 and the second Z-shaped flange 2 are spliced, the outer surfaces of the two channel steel beams 8 are in contact with each other.

[0057] The beam components are welded in the factory. During on-site splicing, the channel steel beam 8 is directly attached to form a continuous support surface. The H-beam 7 and the channel steel beam 8 provide lateral support, optimize load distribution, and avoid local stress concentration.

[0058] Installation process for this triangular steel modular structure:

[0059] S1. The positioning component 5 is inserted between the two inner partitions 4 through the mounting slot 509. The upper and lower ends of the positioning column 501 are limited by the limiting plate 508 to prevent it from coming out.

[0060] S2. Move the first Z-shaped flange 1 toward the second Z-shaped flange 2. The connecting assembly is pushed forward with the module column 3 of the first Z-shaped flange 1. The pushing column 607 begins to approach the driving ear 506 of the positioning assembly 5.

[0061] S3. During the movement, the abutting cylinder 606 of the connecting component first contacts the positioning post 501. Due to the compression of the positioning post 501, the abutting cylinder 606 opens to both sides, causing the elastic connecting plate 604 to rotate and compressing the second torsion spring 605, so as to allow the abutting cylinder 606 to smoothly pass over the positioning post 501.

[0062] S4. When the abutting cylinder 606 completely passes the positioning column 501, the second torsion spring 605 releases its elastic force, causing the elastic connecting plate 604 to close. The abutting cylinder 606 and the positioning column 501 are clamped and engaged. At the same time, the pushing column 607 squeezes and drives the ear 506, which in turn drives the elastic connecting arm 504 to rotate around the first rotating ring 503 as the axis, compressing the first torsion spring 507 and causing the contact block 505 to squeeze the inner wall of the module column 3 on the second Z-shaped flange 2.

[0063] S5. The contact block 505 engages with the inner wall of the module column 3 to form a temporary fixation, so that the first Z-shaped flange 1 is pre-installed on the second Z-shaped flange 2. At this time, the first Z-shaped flange 1 and the second Z-shaped flange 2 are aligned.

[0064] S6. Pre-installation: After ensuring that the first Z-shaped flange 1 and the second Z-shaped flange 2 are aligned, the workers use bolts to fix the exposed parts of the first Z-shaped flange 1 and the second Z-shaped flange 2. At the same time, the outer surfaces of the H-shaped steel beam 7 and the channel steel beam 8 are attached after splicing to form a continuous support surface.

[0065] This invention improves installation strength and efficiency through two installation steps, optimizes the structural redundancy and material waste caused by stacked beams and columns in column-bearing steel modular structures, and eliminates the need for corner fitting sidewall openings, thus avoiding weakening of the node core area. It also overcomes the problem of uneven indoor height caused by staggered unit connections, improving the spatial experience. It eliminates the need to level the floor height of adjacent modules through decoration, reducing construction process and material waste.

[0066] Furthermore, the present invention enables the positioning and installation of the first Z-shaped flange 1 and the second Z-shaped flange 2 during installation through the positioning component and the connecting component. This allows for the convenient installation of high-strength bolts on the first Z-shaped flange 1 and the second Z-shaped flange 2, eliminating the need to install bolts while positioning the Z-shaped flanges during on-site assembly, and also eliminating the need to maintain the stability between the Z-shaped flanges. This reduces the difficulty of installation, improves installation efficiency, and reduces the workload of the workers.

[0067] Please see Figure 11 , Figure 11 Figure a shows a second rectangular module unit c1 incorporating the connection structure of the present invention. During assembly, the middle second rectangular module unit c1 is connected to its upper left and upper right second rectangular module units c1 using the connection structure of the present invention. Similarly, the middle second rectangular module unit c1 is connected to its lower left and lower right second rectangular module units c1 using the connection structure of the present invention. The remaining empty single column c2 and single plate c3 are also connected to the middle second rectangular module unit c1 using the connection structure of the present invention. After assembly, as shown... Figure 11 As shown in b, the assembled second rectangular module unit c1, single column c2, and single plate c3 include the second single beam position structure d1, the second single column position structure d2, and the single plate position structure d3, and are combined with Figure 11 As shown in the enlarged view in section b, the connection structure of this invention can achieve two columns and four beams at the edge nodes and two columns and six beams at the middle nodes, thereby optimizing the structural redundancy and material waste caused by the stacking of beams and columns in the column-bearing steel module structure.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
