Description

Technical Field

[0001] This utility model relates to the field of basement support technology, specifically to a basement support device. Background Technology

[0002] In recent years, super high-rise steel structure buildings have experienced rapid development, especially those over 300 meters tall. These buildings typically have deep basements with complex geological conditions. Currently, the deepest foundation pit for a domestic civil building has reached eight stories, with a depth of -42.5 meters. Due to insufficient geological bearing capacity, some column locations require the installation of grid-shaped punching shear members composed of large-section steel components to meet structural requirements.

[0003] However, the foundation pit support structure of ultra-deep basements is extremely complex. The confined space formed by the basement roof slab and the foundation pit support structure poses a significant challenge to the installation of the grid-shaped punching shear steel beams. Due to the constraints of ground traffic access requirements, the basement roof slab cannot be completely removed, making it difficult to transport the punching shear steel beams to the basement floor slab using conventional vertical hoisting methods.

[0004] Using small lifting equipment to hoist into the basement floor presents numerous limitations in practice. This method is only suitable for shallow basements with unobstructed foundation pit support structures. When facing deep foundation pits with multi-layered support beams, collisions between the lifting equipment boom and the support beams frequently occur. Furthermore, during basement floor slab construction, the dense arrangement of anti-buoyancy anchors in some areas encroaches on the space available for the lifting equipment; and the significant elevation differences within the basement floor area, with adjacent top slabs exhibiting elevation differences exceeding 1 meter, further hinders cross-area operations for the lifting equipment.

[0043] 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.

[0044] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0045] According to an embodiment of the present invention, in one aspect, a basement support device is provided, comprising:

[0046] Multiple support components 1 are arranged crosswise and fixedly connected to form a support beam 2;

[0047] The frame assembly 3 is fixedly installed in the basement. The frame assembly 3 includes multiple support frames 31 and multiple diagonal braces 32. The diagonal braces 32 are set at an angle on one side of the support frame 31. The multiple support frames 31 are arranged parallel to each other or staggered to form an installation position suitable for placing the support beam 2.

[0048] Specifically, in this embodiment, the support beam 2 is a punching shear steel beam. After multiple support components 1 are hoisted into place, they are then welded together to form the support beam 2.

[0049] It is easy to understand that the basement support device provided by this device is set around the giant steel column 4 in the basement to provide support for the giant steel column 4 in the basement.

[0050] This embodiment provides a basement support device, in which the support beam 2 is composed of multiple support components 1 arranged in a cross pattern. The original large-size and heavy integral component is disassembled into individual parts that are easy to transport, allowing it to be transported in sections to the installation position through the existing basement passages. This avoids the problem of having to cut off the entire top slab for conventional vertical hoisting. At the same time, the support component 1 can flexibly adjust the installation path according to the distribution of obstacles such as the support beam 2 and anti-buoyancy anchor rods in the basement and the elevation difference of the bottom slab. Combined with the stable installation position provided by the frame assembly 3, it effectively solves the problems of collision of lifting equipment and limited standing space, and improves the hoisting feasibility and construction efficiency of the support structure for ultra-deep basements.

[0051] Furthermore, the frame component 3 includes:

[0052] The first support structure 33 includes two diagonal braces 32 and a support frame 31. The two diagonal braces 32 are fixedly disposed on both sides of the support frame 31.

[0053] The second support structure 34 includes a diagonal brace 32, two support frames 31, and a connecting beam 35. The connecting beam 35 is vertically fixed between the two support frames 31 to form an H-shaped frame. The diagonal brace 32 is inclinedly arranged on one side of the H-shaped frame, and one end of the diagonal brace 32 is fixedly connected to one of the support frames 31.

[0054] In essence, the first support structure 33, through the diagonal braces 32 on both sides, forms a triangular-like stable structure with the support frame 31, effectively dispersing the load transmitted by the support beam 2 and enhancing the overall anti-overturning capacity. The H-shaped frame of the second support structure 34, combined with the single-sided diagonal brace 32, not only improves lateral stability but also allows for flexible adjustment of the support angle according to the direction of force, adapting to complex load conditions. The two structures work together to provide a reliable installation foundation for the support beam 2 and cleverly avoid obstacles such as multi-layered support beams 2 and anti-buoyancy anchors in the basement, solving the problems of difficult positioning and restricted operation of lifting equipment, significantly improving installation efficiency and structural safety, while reducing construction costs and risks.

[0055] It should be noted that during actual installation, the layout of the first support structure 33 and the second support structure 34 should be planned according to the actual working conditions of the basement and the installation requirements of the support beam 2. When installing the first support structure 33, the two diagonal braces 32 are fixed to both sides of the support frame 31 respectively, and the stability is ensured by welding or bolting to form a stable support structure. When installing the second support structure 34, the two support frames 31 are first vertically fixed, and then horizontally connected by the connecting beam 35 to form an H-shaped frame. Subsequently, the diagonal braces 32 are obliquely fixed to one side of the H-shaped frame and connected to one of the support frames 31.

[0056] Furthermore, the support beam 2 is a "well" shaped support beam, and the first support structure 33 and the second support structure 34 are connected by the "well" shaped support beam, and the support member 1 on the first support structure 33 is perpendicular to the support member 1 on the second support structure 34.

[0057] Specifically, in this embodiment, the "well"-shaped support beam consists of 10 support members 1. Of course, in other embodiments, other numbers of support members 1 may be provided according to the specific shape of the actual hoisting and support device.

[0058] As easily understood, the "well"-shaped support beam forms a grid structure through the crisscrossing support members 1. Compared to the traditional straight support beam 2, its in-plane stiffness is increased, which can evenly distribute the upper load to the first support structure 33 and the second support structure 34, effectively avoiding local stress concentration. When the support beam 2 is subjected to complex loads, the bidirectional force transmission characteristics of the well structure can convert bending moment into axial force, enhancing the overall resistance to deformation.

[0059] Specifically, in this embodiment, there are four first support structures 33 and four second support structures 34. Two first support structures 33 or two second support structures 34 are arranged in pairs, and the two sets of second support components are mirror images of each other in the middle of the overall frame assembly 3. The two first support structures 33 in the first set are arranged in parallel, forming a transverse support axis, with their diagonal braces 32 facing the edge of the basement to enhance lateral stability. The two second support structures 34 that cooperate with them are arranged perpendicular to the first support structures 33, forming a longitudinal support axis through the support beam 2. The diagonal braces 32 on one side are inclined outwards to resist the longitudinal load transmitted by the "well"-shaped support beam. The other set of second support structures 34 is mirror-image arranged, meaning that the orientation of its H-shaped frame and connecting beam 35 is axially symmetrical with the second support structures 34 in the first set, ensuring balanced stress distribution within the basement support system. When the two sets of structures are connected by a "well"-shaped support beam, the transverse support member 1 passes through the support frame 31 of the two sets of first support structures 33 in sequence, while the longitudinal support member 1 crosses the connecting beam 35 of the two sets of second support structures 34, forming a closed well grid.

[0060] Specifically, in this embodiment, four of each of the first support structure 33 and the second support structure 34 are provided. Two first support structures 33 or two second support structures 34 are grouped in pairs, with the two first support structures 33 of the two groups arranged in parallel to form a transverse support axis. The diagonal braces 32 on both sides of the first support structure 33 face the edge of the basement, effectively enhancing lateral stability. The two groups of second support structures 34 arranged perpendicularly to the second support structure 34 form a longitudinal support axis through the support beam 2. The diagonal braces 32 on one side are inclined outward to specifically resist the longitudinal load transmitted by the "well" support beam.

[0061] Furthermore, the support frame 31 includes:

[0062] Two first columns 311 are arranged parallel to the vertical direction;

[0063] Support member 312 is fixedly disposed between two first columns 311 to form an installation position.

[0064] In a straightforward manner, the vertically arranged first column 311 can directly transmit the vertical load from the supporting beam 2 to the bottom of the basement, reducing the horizontal component force and improving structural stability; the support member 312 is erected between the two columns to form a stable horizontal installation position, providing a reliable support surface for the supporting beam 2, effectively dispersing the concentrated load of the supporting beam 2, and avoiding excessive local stress.

[0065] Furthermore, the support frame 31 also includes:

[0066] The limiting member 313 is arranged parallel to the supporting member 312, and the limiting member 313 is located at the ends of the two first columns 311 away from the diagonal brace 32.

[0067] It is easy to understand that the limiting component 313, together with the supporting component 312 and the first column 311, constitute a three-dimensional limiting space, which enhances the fixing effect on the supporting beam 2. Especially in the complex stress environment of ultra-deep basement, it can improve the overall stability and seismic performance of the support system.

[0068] Furthermore, the diagonal brace 32 includes:

[0069] Inclined member 321, one end of which is fixedly connected to support frame 31;

[0070] The second column 322 is set at the other end of the inclined member 321, and the second column 322 is set parallel to the vertical direction;

[0071] The reinforcing rib 323 has one side fixedly connected to the inclined member 321 and the other side fixedly connected to the second column 322.

[0072] In a straightforward manner, the inclined member 321, hinged at one end to the support frame 31 and connected to the second column 322 at the other end, converts the vertical load borne by the support frame 31 into an axial force that is transmitted to the second column 322, effectively reducing the impact of the horizontal component force on the structure. The second column 322, positioned parallel to the vertical direction, can vertically transmit the load from the inclined member 321 to the bottom of the basement, avoiding stress concentration. The reinforcing rib 323 enhances the connection stiffness between the inclined member 321 and the second column 322, increasing the stress-bearing contact surface, improving the joint's resistance to deformation, and preventing cracking at the connection due to repeated stress.

[0073] Furthermore, the frame assembly 3 also includes an anchoring assembly 36, which is located at the bottom of the support frame 31 or the diagonal brace 32 in the vertical direction and is fixedly connected to the basement.

[0074] It is easy to understand that by adding an anchoring component 36 to the frame assembly 3, the frame assembly 3 and the bottom of the basement are formed into a solid whole through the rigid connection of the anchoring component 36, which effectively prevents the frame assembly 3 from displacing or overturning under complex loads and improves the overall stability of the support system.

[0075] Furthermore, the anchoring component 36 includes:

[0076] Fixed embedded part 361 is pre-embedded in the basement;

[0077] The pre-embedded connector 362 is fixedly connected to the fixed embedded part 361, and a fixed position suitable for connection with the support frame 31 or the diagonal brace 32 is formed on the pre-embedded connector 362.

[0078] As is easily understood, the fixed embedded part 361 is pre-embedded in the basement structure and can fully interlock with the concrete to form a stable anchor foundation; the pre-embedded connecting part 362 is firmly connected to the fixed embedded part 361 and is provided with a fixed position for the adapted support frame 31 or the diagonal brace 32, thus realizing the rigid connection between the frame assembly 3 and the basement structure.

[0079] In an optional embodiment, if the basement structure is already formed and pre-embedding is not possible, a post-anchoring scheme can be used, such as using high-strength chemical anchors or mechanical anchors to directly fix the anchor plate to the basement floor or side wall. Anchoring is achieved through the bond force between the anchor and the concrete or the mechanical locking action, thus quickly completing the installation of the frame component 3.

[0080] According to an embodiment of the present invention, another aspect provides a method for installing a basement support device, applied to the basement support device described above, comprising the following steps:

[0081] First, a lifting point support 51 is installed outside the basement. A lifting ring 52 and a steel wire rope 53 are installed on the support 1 to form a lifting connection system.

[0082] Meanwhile, hoisting openings are reserved in the basement ceiling, and frame components 3 are pre-installed inside the basement;

[0083] Next, the support component 1 is hoisted to the predetermined height;

[0084] Then, by setting a ring chain 54 and a chain hoist 55 on the support member 1, the position of the support member 1 is adjusted in stages by gradually transferring the load. After each load transfer is completed, the corresponding wire rope 53 or chain hoist 55 is released until the support member 1 is adjusted to the design plane position and fixed by the chain hoist 55.

[0085] Finally, dismantle the hoisting equipment in sequence, seal the hoisting openings, and complete the installation.

[0086] This combination Figures 7 to 12 As shown, the installation method of the basement support device is described in detail. Specifically, when setting up the lifting point support 51 on the outside of the basement, the position and load-bearing capacity of the lifting point must be calculated based on the weight and size of the support 1 and the structural layout of the basement to ensure that the lifting point support 51 can stably bear the lifting load. The lifting point support 51 is usually made of steel or concrete foundation. The lifting ring 52 set on its top surface must have sufficient strength and toughness and be firmly connected to the lifting point support 51 by high-strength bolts or welding. The matching wire rope 53 should be selected with appropriate specifications according to the lifting weight to ensure that the safety factor meets the construction requirements. The wire rope 53 is reliably connected to the lifting ring 52 and the support 1 by shackles to form a complete lifting connection system.

[0087] Specifically, a hoisting opening is reserved in the basement ceiling slab. The opening size must be slightly larger than the maximum cross-sectional size of the wire rope 53 to ensure the wire rope 53 can pass through smoothly. When reserving the opening, the ceiling structure around the opening needs to be temporarily reinforced to prevent deformation or damage to the ceiling slab during hoisting. The frame assembly 3 is pre-installed inside the basement. Before installation, the support frame 31, diagonal brace 32, anchoring assembly 36, etc., need to be fully inspected to ensure that the dimensional accuracy and connection strength of each component meet the design requirements. According to the design drawings, the first support structure 33 and the second support structure 34 are positioned and firmly connected to the basement floor slab or side wall through the anchoring assembly 36 to provide a stable foundation for the subsequent installation of the support component 1.

[0088] It should be noted that the design of the hoisting opening avoids the drawbacks of cutting and installing the basement roof slab and operating the hoisting equipment inside the basement. Compared to the traditional method of cutting off the entire roof slab, the hoisting opening only needs to be created according to the specific dimensions of the wire rope 53, reducing the amount of structural demolition and subsequent repair work. This lowers construction costs and avoids damage to the overall structure of the basement roof slab, ensuring the building's safety performance. Furthermore, by placing the hoisting equipment outside the basement, the limitations imposed by multiple supporting beams, dense anti-buoyancy anchors, and differences in floor elevation within the basement are effectively avoided. There is no need to lower large lifting equipment to the basement floor slab, completely resolving issues such as collisions between the equipment boom and supporting beams, and insufficient standing space.

[0089] Specifically, when using an external hoisting mechanism 6 (such as a tower crane or truck crane) to lift the support component 1 to the predetermined height, the lifting points must be reasonably set according to the center of gravity of the support component 1 to ensure that the support component 1 remains balanced during the hoisting process and to avoid tilting or overturning. Before hoisting, a comprehensive inspection of the hoisting mechanism's braking system, wire rope 53, hook, etc., should be carried out to ensure that the equipment is in good working order. During the hoisting process, a dedicated person should be assigned to direct the operation and maintain close communication with the hoisting operators through walkie-talkies or other communication equipment. The hoisting speed and height should be strictly controlled to avoid the support component 1 colliding with the basement structure or other obstacles due to excessive speed or improper operation. When the support component 1 is hoisted to the predetermined height, which is a certain distance above the basement ceiling, the hoisting should be paused to prepare for the next step of adjusting its position.

[0090] Specifically, a chain hoist 54 and a chain reel 55 are installed on the support component 1, and the position of the support component 1 is adjusted in stages by gradually transferring the load. First, the support component 1 is connected to a pre-set temporary fixing point inside the basement via the chain hoist 54, ensuring that the chain hoist 54 is firmly connected and has a certain adjustment margin. Then, the steel wire rope 53 is slowly released, transferring part of the load to the chain hoist 54. At this time, the stability and positional changes of the support component 1 are carefully observed. Next, the chain reel 55 is used to further fine-tune the horizontal and vertical position of the support component 1, gradually bringing it closer to the design plane position. After each load transfer and position adjustment is completed, the stress on each connecting component is checked. After confirming that there are no abnormalities, the corresponding steel wire rope 53 or chain reel 55 is released. The above operation is repeated until the support component 1 is precisely adjusted to the design plane position via the chain reel 55, and the support component 1 is firmly fixed to the frame assembly 3 using high-strength bolts or welding, ensuring that the connection strength meets the design requirements.

[0091] It should be noted that, refer to Figures 8 to 11As shown, the transportation process of support component 1 requires the establishment of transfer and installation points on both sides of the basement, with corresponding chain hoists 54 and chain hoists 55 installed at these points. Areas with stable structures and easy operation are preferred as transfer and installation points. Sturdy fixed supports must be pre-installed at the transfer and installation points to provide reliable leverage points for the chain hoists 54 and chain hoists 55, ensuring they can withstand the tension and gravity during the transportation of support component 1. When support component 1 is hoisted to the transfer and installation point on one side of the basement, the operator quickly connects the chain hoist 54 to support component 1, while simultaneously using the chain hoist 55 to fine-tune the angle and position of support component 1, allowing part of support component 1 to first fall onto the support frame 31. Subsequently, through the coordination of the chain hoist 54 and chain hoist 55 at the transfer and installation point on the other side, using alternating tightening and loosening, support component 1 is slowly moved laterally along a predetermined path to the target installation area. During this process, the chain hoist 55 continuously and dynamically calibrates the position of support component 1 to ensure it does not collide with obstacles such as pipelines inside the basement during transportation. After the support component 1 reaches the target position, the height and horizontal position are adjusted again with the help of the chain hoist 55, and finally the support component 1 and the frame assembly 3 are stably connected, thus completing the entire transfer and installation process.

[0092] Specifically, when dismantling the hoisting equipment in sequence, first disconnect the support component 1 from the chain 54 and chain hoist 55, and then gradually dismantle the wire rope 53, lifting ring 52, and other hoisting components. During the dismantling process, take care to protect the basement structure and avoid structural damage caused by the dismantling operation. After dismantling, seal the hoisting opening. First, clean up debris and dust around the opening, and then pour concrete of the same strength grade as the basement roof slab. During the pouring process, ensure that the concrete is vibrated and compacted to avoid quality defects such as honeycombing and voids. After the concrete reaches the design strength, perform surface treatment on the sealed area to make it consistent with the appearance of the surrounding roof slab structure, thus completing the installation of the entire basement support device.
