Description

Technical Field

[0001] This utility model belongs to the field of steel corridor construction technology, specifically relating to a special support frame for steel corridor assembly. Background Technology

[0002] Large, high-rise connected structures typically consist of two spaced-apart buildings. To meet the functional requirements of this type of architecture, high-altitude steel connecting corridors are usually used to link them. The bottom of the connecting corridor is usually the basement roof or the roof of the podium. The steel connecting corridor is generally assembled before being hoisted. Since large steel connecting corridors can sometimes weigh hundreds of tons, and the podium is generally used as a lobby, the beam span is usually large to ensure space requirements. The weight of the steel connecting corridor far exceeds the design load-bearing capacity of the podium roof beams. Current technology usually involves setting up multiple support frames on the basement structural columns, directly below the projection plane of the steel connecting corridor installation location, reaching the elevation of the podium roof. On the support frames, the various parts of the steel connecting corridor are assembled into an integral lifting unit. The overall lifting operation is completed by a hydraulic lifting device before the construction of the podium roof is carried out. However, in this case, the support frames are usually quite high, so stability cannot be guaranteed. Furthermore, existing support frames often use integral welded frame structures, which are bulky, difficult to transport and hoist at high altitudes, inconvenient to disassemble, have poor reusability, and significantly increase construction costs.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] 1. This utility model uses multiple support units that can be detachably stacked vertically to form support columns. Connecting components are used to detachably connect prefabricated columns, horizontal members, and diagonal members to form support units. This not only avoids the cumbersome structure of traditional integral welded frames, significantly reducing transportation and high-altitude hoisting difficulties, but also facilitates disassembly and assembly, has a high reusability rate, and causes no structural damage after disassembly. It is suitable for repeated use in multiple projects, effectively reducing construction costs and improving construction efficiency. By setting diagonal bracing components between the support columns and the base frame, the three together form a triangular stable system, increasing the stability of the support frame and ensuring the safety of the steel corridor assembly process. Two sets of rectangular support units, with their inner left and right end faces in contact with the podium roof steel frame and their upper and lower end faces not in contact with the podium roof steel frame, not only ensure that the load of the steel corridor is evenly transferred to the support columns, preventing overloading of the podium roof, but also further strengthen the anti-tilting ability of the support frame, thereby improving the stability and safety of the structure.

[0017] 2. This utility model uses slots at both ends of the column and inserts of the connector to cooperate with the first bolt holes distributed circumferentially, ensuring the axial alignment of the upper and lower support units and the transfer of loads while realizing the rapid assembly and disassembly of the support units; by bolting the connector to the column of the installation component and bolting the horizontal and diagonal bars to the connector and installation component, all connection nodes are designed to be detachable, making the jig easy and quick to assemble and disassemble, improving construction efficiency, and also facilitating transportation and reuse, thus reducing construction costs. The horizontal and diagonal bars set in each support unit can form a multi-layer rectangular frame and truss structure, which, combined with the high bending resistance of the I-beam base frame, improves the overall load-bearing capacity and stability of the structure.

[0018] 3. This utility model effectively increases the rigidity and stability of the connection node between columns by setting a reinforcing frame with a triangular reinforcing plate on the connection, avoids stress concentration at the node, effectively suppresses the torsional deformation of the connecting parts under stress, and thus improves construction safety.

[0019] 4. This utility model, through the cooperation of the second cross-shaped through hole in the middle of the column and the mounting parts, allows the installation positions of the middle horizontal bar, the first diagonal bar and the second diagonal bar to be adjusted according to actual needs, increasing the flexibility of the support frame, while the bolt connection also ensures the stability of the connection.

[0020] 5. This utility model achieves the adjustment of the length of the diagonal brace through the sliding cooperation between the first and second support rods and the fixing of the fixing bolts, thereby enabling the frame to adjust the angle and length of the diagonal brace according to the actual construction conditions to adapt to different working conditions.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0035] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0036] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0038] like Figure 1 As shown, a special support frame for steel corridor assembly includes: a base frame 1; a support column 3 mounted on the base frame 1, consisting of at least two support units 2 detachably connected in the vertical direction; a rectangular support unit 4 fixedly connected to the top of the support column 3, with its inner left and right ends in contact with the steel frame of the podium roof and its upper and lower ends not in contact with the steel frame of the podium roof; and an inclined bracing assembly 5 detachably connected between the support column 3 and the base frame 1. The support unit 2 includes: four uprights 6 arranged in a rectangle; a horizontal bar assembly that connects adjacent uprights 6 laterally to form a multi-layer rectangular frame structure; an inclined bracing assembly that connects adjacent uprights 6 at an angle; and a connecting assembly mounted on the uprights 6 to achieve detachable connections between the upper and lower uprights 6, between the horizontal bar assembly and the vertical bracing assembly, and between the inclined bracing assembly and the uprights 6.

[0039] It should be noted that: the base frame 1 consists of two parallel I-beams. The base frame 1 needs to be fixed to the top surface of the structural columns on the basement roof slab using embedded parts (such as embedded bolts). The length and spacing of the base frame 1 need to be determined based on the projected dimensions of the steel connecting corridor. The specific model of the base frame 1 needs to be selected based on the actual load requirements of the project.

[0040] In practice, the base frame 1 is first installed on the basement roof slab as the foundation of the entire support frame. Then, the horizontal members are connected laterally to adjacent columns 6 to form a multi-layer rectangular frame structure. The diagonal members are connected obliquely between adjacent columns 6 to form a truss structure, which is then assembled to form support units 2. Multiple support units 2 are then detachably connected and stacked vertically to form support columns 3 of the designed height. The height of support columns 3 should be lower than the steel frame of the podium roof. Finally, diagonal bracing components 5 are installed between the columns 6 of support columns 3 and the base frame 1, so that the support columns 3, base frame 1, and diagonal bracing components 5 together form a triangular stable system, thus improving the support frame. To ensure stability, the rectangular support unit 4 is then installed on the connecting assembly at the top of the support column 3, ensuring that its inner left and right ends are in contact with the steel frame of the podium roof, while its upper and lower ends do not contact the steel frame of the podium roof. This completes the overall installation of the support frame. After the support frame is installed, a load test is conducted to monitor the verticality deviation of the support column 3 and the slippage of each connecting bolt node, ensuring the stability and safety of the support frame. After the top steel corridor components are assembled, forming an overall lifting unit and hydraulically lifted, the construction personnel disassemble the bolts in reverse order and recover the support unit 2, diagonal brace component 5, and other components for recycling, effectively improving the reuse rate and reducing construction costs.

[0041] like Figure 2 As shown, the connecting assembly includes: connectors 7 detachably connected to both ends of the column 6, and mounting pieces 8 detachably connected to the column 6. The crossbar assembly includes: four top crossbars 9 bolted to the top connectors 7 of adjacent columns 6 at both ends, four bottom crossbars 11 bolted to the bottom connectors 7 of adjacent columns 6 at both ends, and four middle crossbars 10 bolted to the mounting pieces 8 of adjacent columns 6 at both ends. The diagonal bar assembly includes: a first diagonal bar 12 inclined between the top crossbars 9 and the middle crossbars 10, and a second diagonal bar 13 inclined between the bottom crossbars 11 and the middle crossbars 10. The ends of the first diagonal bar 12 and the second diagonal bar 13 are respectively bolted to the connectors 7 and the mounting pieces 8.

[0042] The top crossbar 9, the middle crossbar 10, and the top crossbar 9 are fixedly connected to the connector 7 and the mounting piece 8 respectively by bolts to form a three-layer rectangular frame structure, which improves the stability of the connecting components. The first diagonal bar 12 and the second diagonal bar 13 are fixed to the connector 7 and the mounting piece 8 respectively by bolts, further forming a spatial truss structure, which can convert horizontal loads into axial forces, significantly improving the bending and shear resistance of the support unit 2. All connection nodes are detachable, and the components are free from welding damage, which makes the jig easy and quick to assemble and disassemble, improving construction efficiency, and also facilitating transportation and reuse, thus reducing overall costs.

[0043] like Figure 3 and Figure 4As shown, the column 6 has slots 15 at both ends. The connector 7 includes a connecting plate 14, a plug 16 located in the middle of the connecting plate 14 and insertable into the slot 15, and two reinforcing frames 17 and two connecting frames 18 slidably disposed on the connecting plate 14. The reinforcing frames 17 and connecting frames 18 are arranged in a cross shape. The top crossbar 9 and the bottom crossbar 11 are respectively connected to the connecting frames 18 by bolts. The connecting plate 14 has a plurality of first bolt holes 19 evenly distributed around its circumference. Adjacent support units 2 are longitudinally stacked and connected by bolts passing through the first bolt holes 19.

[0044] The support unit 2 is positioned by being inserted into the slots 15 at both ends of the column 6 and the plug blocks 16 of the connector 7. The first bolt holes 19 distributed around the perimeter penetrate the connecting plate 14 to achieve rapid centering and stacking of the upper and lower support units 2. This ensures the axial alignment of the upper and lower support units 2 and the transfer of loads, while also enabling the rapid assembly and disassembly of the support unit 2. At the same time, through the cross-shaped distribution design of the reinforcing frame 17 and the connecting frame 18, the top crossbar 9, the bottom crossbar 11 and the rectangular plate 25 on the connecting frame 18 are bolted together to form a multi-layer rectangular frame, ensuring that the vertical load is evenly transferred along the column 6 to the base frame 1 and the basement structural column.

[0045] The reinforcing frame 17 includes: a first top plate 20 slidably connected to the connecting plate 14, a first vertical plate 21 connected to one side of the first top plate 20, and a triangular reinforcing plate 22 connected between the first top plate 20 and the first vertical plate 21; the connecting frame 18 includes: a second top plate 23 slidably connected to the connecting plate 14, a second vertical plate 24 connected to one side of the second top plate 23, and a rectangular plate 25 connected between the second top plate 23 and the second vertical plate 24; the top crossbar 9, the bottom crossbar 11, the first diagonal bar 12, and the second diagonal bar 13 are connected to the rectangular plate 25 by bolts; the side wall of the slot 15, the first vertical plate 21, and the second vertical plate 24 are all provided with second bolt holes 26; the insert block 16 is provided with multiple sets of first cross-shaped through holes 27 adapted to the second bolt holes 26; the insert block 16, the first vertical plate 21, and the second vertical plate 24 are bolted to the column 6.

[0046] It should be noted that the first top plate 20 and the second top plate 23 can both be set as T-shaped structures. The connecting plate 14 is provided with a T-shaped slot adapted to the T-shaped structure. The plug-in connection method realizes the precise alignment and rapid splicing of the reinforcing frame and the connecting frame on the connecting plate, reduces the splicing and alignment time, and improves construction efficiency.

[0047] The reinforcing frame with triangular reinforcing plates effectively increases the rigidity and stability of the connection nodes between columns, avoids stress concentration at the nodes, effectively suppresses the torsional deformation of the connectors under stress, and thus improves construction safety.

[0048] like Figure 4 and Figure 5 As shown, the column 6 has multiple sets of cross-shaped through holes spaced along its length in the middle. The mounting component 8 includes a third vertical plate 29 and mounting plates 30 connected to both sides of the third vertical plate 29. The third vertical plate 29 has a third bolt hole 31. The mounting component 8 and the column 6 are connected by bolts through the third bolt hole 31 and the second cross-shaped through hole. The middle horizontal bar 10, the first diagonal bar 12 and the second diagonal bar 13 are bolted to the mounting plate 30. The cooperation between the second cross-shaped through hole and the mounting component allows the installation positions of the middle horizontal bar, the first diagonal bar and the second diagonal bar to be adjusted according to actual needs, increasing the flexibility of the support frame. At the same time, the bolt connection also ensures the stability of the connection.

[0049] It should be noted that the first cross-shaped through hole 27 on the insert 16 and the second cross-shaped through hole 28 on the column 6 are both formed by the intersection of two through holes that are orthogonally connected along the width and thickness directions.

[0050] like Figure 6 As shown, the rectangular support unit 4 includes: a top frame 32 bolted to the connecting plate 14 at the top of the support column 3; two vertical frames 33 vertically connected to both ends of the top frame 32; and a support frame 34 connected between the two vertical frames 33 and parallel to the top frame 32. The top frame 32 and the support frame 34 are detachably connected to the vertical frames 33 by fixing components 35. The top frame 32, the support frame 34 and the vertical frames 33 are all I-beams.

[0051] It should be noted that, since the upper and lower ends of the rectangular support unit do not contact the steel frame of the podium roof, the length of the vertical frame should be greater than the longitudinal length of the steel frame of the podium roof.

[0052] During the installation of the rectangular support unit, the top frame 32 is first installed on the connecting plate 14, and then the vertical frame 33 is installed on the top frame 32 so that the sides of the vertical frames 33 are in contact with the steel frame of the podium roof. Then, the support frame 34 is installed on the vertical frame. The top frame and the support frame are connected by the vertical frame to form a rigid rectangular frame, which directly supports the steel corridor lifting unit. The concentrated load is distributed to the support column by the high bending resistance of the I-beam. The vertical frame is in lateral contact with the steel frame of the podium roof. The horizontal displacement of the steel frame is limited by the contact friction of the I-beam flange and the stiffness of the vertical frame itself, which indirectly enhances the cooperative anti-lateral displacement ability of the frame and the existing structure, thereby improving the stability and safety of the structure.

[0053] like Figure 7As shown, the fixing component 35 includes: a fixing block 36, a fixing plate 37 connected to one side of the fixing block 36 and forming an L-shaped structure therewith, and a T-shaped groove 38 disposed on the side of the fixing block 36 away from the fixing plate 37 and open at both ends. The fixing plate 37 and the web of the vertical frame 33 are provided with a fourth bolt hole 39, and the wing plate of the top frame 32, the wing plate of the support frame 34, and the fixing block 36 are provided with a fifth bolt hole 40. The fixing block 36 is engaged with the upper end of the top frame 32 or the lower end of the support frame 34 through the T-shaped groove 38 and is fastened by bolts passing through the fifth bolt hole 40. The fixing plate 37 is connected to the vertical frame 33 by bolts.

[0054] Preferably, a triangular stiffening plate 41 is connected between the fixing plate 37 and the fixing block 36. The triangular stiffening plate 41 enhances the bending stiffness of the connection node and prevents the I-beam vertical frame from buckling locally under load.

[0055] like Figure 8 As shown, the diagonal bracing assembly 5 includes: an adjustable-length diagonal bracing rod 42; a first U-shaped hinge seat 43 hinged to one end of the diagonal bracing rod 42 and connected to the column 6; and a second U-shaped hinge seat 44 hinged to one end of the diagonal bracing rod 42 and connected to the base frame 1. The first U-shaped hinge seat 43 is provided with a sixth bolt hole that matches the cross-shaped through hole on the column 6. A seventh bolt hole 45 is provided through the wing plate of the base frame 1 and the second U-shaped hinge seat 44. The first U-shaped hinge seat 43 is connected to the column 6 by bolts, and the second U-shaped hinge seat 44 is connected to the base frame 1 by bolts.

[0056] The diagonal brace 42 includes: a first brace 46 that is hollow inside and open at one end; a second brace 47 that is slidably disposed at one end inside the first brace 46; a second fixing hole 49 that is equally spaced along the length of the second brace 47; a first fixing hole 48 that is disposed near the opening of the first brace 46 and is adapted to the second fixing hole 49; and a fixing bolt that passes through the first fixing hole 48 and the second fixing hole 49 for fixing the second brace 47.

[0057] The two ends of the diagonal brace 42 are connected to the support column 3 via the first U-shaped hinge seat 43 and the base frame 1 via the second U-shaped hinge seat 44, forming an inclined triangular support structure. The extension length of the second brace 47 within the first brace 46 can be adjusted by aligning and locking the first fixing hole 48 and the second fixing hole 49. This allows the frame to adjust the angle and length of the diagonal brace according to the actual construction conditions to adapt to different working conditions, actively offset the lateral force during construction, and share the bending moment of the support column 3 through the axial compressive strength of the diagonal brace 42, thereby improving the overall anti-overturning stability.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail can be made without departing from the spirit and scope of this utility model as defined in the appended claims.
