Description

Technical Field

[0001] The present invention relates to the technical field of basement support, and in particular to a basement support device and an installation method thereof. Background Art

[0002] In recent years, super-tall steel structures have experienced rapid growth, particularly those over 300 meters tall. These structures often feature deep basements and complex geological conditions. Currently, the deepest foundation pit for a domestic civil building reaches eight stories, at a depth of -42.5 meters. Due to insufficient geological bearing capacity at some column locations, shear-resistant structures constructed of large-section steel members are required to meet structural requirements.

[0003] However, the ultra-deep basement's foundation pit support structure is extremely complex. The confined space between the basement roof and the pit support structure presents a significant challenge for the installation of the crisscross-shaped shear beams. Due to the need for surface transportation, the basement roof cannot be completely removed, making it difficult to transport the shear beams to the basement floor using conventional vertical lifting methods.

[0004] Using small cranes to reach the basement floor for lifting presents numerous practical limitations. This method is only suitable for shallow basements with unobstructed foundation pit support structures. When working with deep pits with multiple layers of supporting beams, collisions between the crane boom and the supporting beams are common. Furthermore, during basement floor construction, densely packed anti-floating anchors in some areas squeeze the crane's station space. The large elevation differences between adjacent roofs, which can reach over 1 meter, further hinder cross-regional crane operations. Summary of the Invention

[0049] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0050] The following combination Figures 1 to 6 , describing embodiments of the present invention.

[0051] According to an embodiment of the present invention, in one aspect, a basement support device is provided, comprising:

[0052] A plurality of supporting members 1 are cross-arranged and fixedly connected to form a supporting beam 2;

[0053] The frame assembly 3 is fixedly installed in the basement. The frame assembly 3 includes multiple supporting frames 31 and multiple diagonal braces 32. The diagonal braces 32 are arranged at an angle on one side of the supporting frame 31. The multiple supporting frames 31 are parallel to each other or staggered to form an installation position suitable for placing the supporting beam 2.

[0054] Specifically, the support beam 2 in this embodiment is a punching-resistant steel beam. After a plurality of support members 1 are hoisted into place, they are fixed by welding to form the support beam 2.

[0055] It is easy to understand that the basement supporting device provided by the present device is arranged around the giant steel columns 4 in the basement to provide supporting force for the giant steel columns 4 in the basement.

[0056] This embodiment provides a basement support device, in which the support beam 2 is composed of a plurality of support members 1 arranged crosswise, which disassembles the originally large-sized and heavy integral components into individual components that are easy to carry, so that they can be transported in sections to the installation position through the existing passages in the basement, avoiding the problem of conventional vertical lifting that requires the entire top plate to be cut off; at the same time, the support member 1 can flexibly adjust the installation path according to the distribution of obstacles such as the support beam 2 and anti-floating anchor rods in the basement and the elevation difference of the bottom plate. 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, thereby improving the lifting feasibility and construction efficiency of the ultra-deep basement support structure.

[0057] Furthermore, the frame assembly 3 includes:

[0058] A first supporting structure 33, the first supporting structure 33 includes two diagonal bracing members 32 and a supporting frame 31, and the two diagonal bracing members 32 are fixedly arranged on both sides of the supporting frame 31;

[0059] The second supporting structure 34 includes a diagonal support member 32, two supporting frames 31 and a connecting beam 35. The connecting beam 35 is vertically fixed between the two supporting frames 31 to form an H-shaped frame. The diagonal support member 32 is obliquely arranged on one side of the H-shaped frame, and one end of the diagonal support member 32 is fixedly connected to one of the supporting frames 31.

[0060] As can be easily understood, the first supporting structure 33, through the diagonal braces 32 on both sides and the supporting frame 31, forms a triangular stable structure that effectively disperses the load transmitted by the supporting beam 2 and enhances the overall anti-overturning capability. The H-shaped frame of the second supporting 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 to accommodate complex load conditions. The two work together to not only provide a reliable installation foundation for the supporting beam 2, but also cleverly avoid obstacles such as multiple layers of supporting beams 2 and anti-floating anchors in the basement, solving the problems of difficult positioning of lifting equipment and limited operation, significantly improving installation efficiency and structural safety, while also reducing construction costs and risks.

[0061] It should be noted that during actual installation, the layout of the first and second support structures 33 and 34 must be planned based on the actual working conditions of the basement and the installation requirements of the support beams 2. When installing the first support structure 33, two diagonal braces 32 are fixed to either side of the support frame 31, secured by welding or bolts to ensure stability and form a stable support structure. When installing the second support structure 34, the two support frames 31 are first fixed vertically and then connected horizontally with a connecting beam 35 to form an H-shaped frame. The diagonal braces 32 are then fixed at an angle to one side of the H-shaped frame, connecting to one of the support frames 31.

[0062] Furthermore, the support beam 2 is a "well"-shaped support beam, 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 and the support member 1 on the second support structure 34 are arranged vertically.

[0063] Specifically, in this embodiment, the "well"-shaped support beam is composed of 10 support members 1. Of course, in other embodiments, other numbers of support members 1 can be provided according to the actual hoisting and the specific shape of the support device.

[0064] As can be easily understood, the "well"-shaped support beam, formed by the crisscrossing support members 1, forms a grid-like structure. Compared to traditional linear support beams 2, its in-plane stiffness is increased, evenly distributing the upper load to the first and second support structures 33 and 34, effectively avoiding localized stress concentration. When the support beam 2 is subjected to complex loads, the bidirectional force transmission characteristics of the well-shaped structure convert bending moments into axial forces, enhancing the overall deformation resistance.

[0065] 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 form a group of two, and the two groups of second support assemblies are mirror images of each other in the center of the integral frame assembly 3. The two first support structures 33 in the first group are arranged parallel to each other, forming a transverse support axis. Their diagonal braces 32 face the basement edge to enhance lateral stability. The two second support structures 34, which are paired with the first support structures 33, are arranged perpendicular to the first support structures 33, forming a longitudinal support axis through the support beam 2. The single-sided diagonal brace 32 is tilted outward to resist the longitudinal load transmitted by the "well" support beam. The other group of second support structures 34 is mirrored, with its H-shaped frame and connecting crossbeam 35 oriented in an axially symmetrical relationship with the first group of second support structures 34, ensuring balanced load distribution within the basement. When the two groups of structures are connected by the "well" support beam, the horizontal support member 1 passes through the support frame 31 of the two groups of first support structures 33 in sequence, and the longitudinal support member 1 spans the connecting beam 35 of the two groups of second support structures 34, forming a closed well grid.

[0066] Specifically, in this embodiment, four first support structures 33 and four second support structures 34 are provided. Two first support structures 33 or two second support structures 34 are grouped in pairs. The two first support structures 33 in each group are arranged in parallel, forming a transverse support axis. The diagonal braces 32 on either side of the two groups face the basement edge, effectively enhancing lateral stability. The two groups of second support structures 34, arranged perpendicular to the two groups, form a longitudinal support axis through the support beam 2. The diagonal braces 32 on each side are tilted outward, specifically resisting the longitudinal load transmitted by the "well" support beam.

[0067] Furthermore, the support frame 31 includes:

[0068] Two first columns 311, the two first columns 311 are arranged parallel to the vertical direction;

[0069] The supporting member 312 is fixedly disposed between the two first columns 311 to form a mounting position.

[0070] It is easy to understand that the vertically arranged first column 311 can directly transmit the vertical load transmitted by the supporting beam 2 vertically to the bottom of the basement, reducing the horizontal component and improving the structural stability; the supporting member 312 is erected between the two columns to form a stable horizontal installation position, providing a reliable supporting surface for the supporting beam 2, effectively dispersing the concentrated load of the supporting beam 2, and avoiding excessive local stress.

[0071] Furthermore, the support frame 31 further includes:

[0072] The limiting member 313 is arranged parallel to the supporting member 312 and is arranged at ends of the two first columns 311 away from the diagonal supporting member 32 .

[0073] It is easy to understand that the limiting member 313, the supporting member 312 and the first column 311 together constitute a three-dimensional limiting space, which enhances the fixing effect of the supporting beam 2, especially in the complex stress environment of an ultra-deep basement, and can improve the overall stability and seismic performance of the supporting system.

[0074] Furthermore, the diagonal bracing member 32 includes:

[0075] An inclined rod 321, one end of which is fixedly connected to the support frame 31;

[0076] A second column 322 is provided at the other end of the inclined rod 321 , and the second column 322 is provided parallel to the vertical direction;

[0077] The reinforcing rib 323 has one surface fixedly connected to the inclined rod 321 and the other surface fixedly connected to the second column 322 .

[0078] As can be easily understood, the inclined rod 321 is hinged at one end to the support frame 31 and connected to the second column 322 at the other end. This 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 force component on the structure. The second column 322 is arranged parallel to the vertical direction, vertically transmitting the load from the inclined rod 321 to the basement floor, thereby avoiding stress concentration. The provision of reinforcing ribs 323 enhances the connection rigidity between the inclined rod 321 and the second column 322. By expanding the load-bearing contact surface, the deformation resistance of the joint is improved, and cracking at the connection due to repeated stress is prevented.

[0079] Furthermore, the frame assembly 3 further includes an anchor assembly 36 , which is disposed at the bottom end of the support frame 31 or the diagonal brace 32 in the vertical direction and is fixedly connected to the basement.

[0080] It is easy to understand that by adding an anchoring assembly 36 to the frame assembly 3, the frame assembly 3 and the bottom of the basement are rigidly connected to form a solid whole, which effectively prevents the frame assembly 3 from being displaced or overturned under complex loads, thereby improving the overall stability of the support system.

[0081] Furthermore, the anchor assembly 36 includes:

[0082] The fixed embedded part 361 is pre-buried in the basement;

[0083] The embedded connecting piece 362 is fixedly connected to the fixed embedded piece 361 , and a fixing position suitable for connecting with the supporting frame 31 or the diagonal bracing piece 32 is formed on the embedded connecting piece 362 .

[0084] It is easy to understand that the fixed embedded parts 361 are pre-buried in the basement structure and can fully engage with the concrete to form a stable anchoring foundation; the pre-embedded connecting parts 362 are firmly connected to the fixed embedded parts 361, and a fixing position of the adaptive support frame 31 or the diagonal brace 32 is set to realize the rigid connection between the frame assembly 3 and the basement structure.

[0085] In an optional embodiment, if the basement structure has been formed and the pre-embedded method cannot be used, a post-anchoring solution can be selected, such as using high-strength chemical anchors or mechanical anchors to directly fix the anchor plate to the basement floor or side wall. The anchoring is achieved through the bonding force between the anchor bolts and the concrete or the mechanical locking action, and the installation of the frame assembly 3 is quickly completed.

[0086] According to another aspect of an embodiment of the present invention, a method for installing a basement support device is provided, which is applied to the basement support device described above and includes the following steps:

[0087] First, a lifting point support 51 is set outside the basement, and a lifting ring 52 and a steel wire rope 53 are set on the support 1 to form a lifting connection system;

[0088] At the same time, a hoisting hole is reserved on the basement roof, and the frame component 3 is pre-installed inside the basement;

[0089] Next, the support member 1 is hoisted to a predetermined height;

[0090] Then, by setting a ring chain 54 and a fall chain 55 on the support member 1, the position of the support member 1 is adjusted in stages in a manner of gradually transferring the load. Each time the load transfer is completed, the corresponding wire rope 53 or fall chain 55 is released until the support member 1 is adjusted to the designed plane position and fixed by the fall chain 55;

[0091] Finally, remove the lifting equipment in sequence, seal the lifting hole, and complete the installation.

[0092] Combined here Figures 7 to 12 As shown, the installation method of the basement support device is specifically described. Specifically, when setting the lifting point support 51 outside the basement, it is necessary to calculate the lifting point position and load-bearing capacity based on the weight, size and basement structural layout of the support 1 to ensure that the lifting point support 51 can stably withstand 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 must be selected with appropriate specifications according to the lifting weight to ensure that the safety factor meets the construction requirements, and the wire rope 53 must be reliably connected to the lifting ring 52 and the support 1 through a shackle to form a complete lifting connection system.

[0093] Specifically, a hoisting hole is reserved in the basement roof, and the hole size needs to be slightly larger than the maximum cross-sectional size of the wire rope 53 to ensure that the wire rope 53 can pass smoothly. When reserving the hole, the roof structure around the hole needs to be temporarily reinforced to avoid deformation or damage to the roof during the hoisting process. The frame assembly 3 is pre-installed inside the basement. Before installation, a comprehensive inspection of the support frame 31, diagonal bracing members 32, anchoring assembly 36, etc. is required to ensure that the dimensional accuracy and connection strength of each component meet the design requirements. According to the design drawings, the first supporting structure 33 and the second supporting structure 34 are positioned and firmly connected to the basement floor or side wall through the anchoring assembly 36 to provide a stable foundation for the subsequent installation of the supporting member 1.

[0094] It should be noted that the setting of the lifting opening avoids the disadvantages of cutting out the basement roof for installation and operating the lifting equipment inside the basement. Compared with the traditional method of cutting out the roof as a whole, the lifting opening only needs to be opened according to the specific size of the wire rope 53, which reduces the amount of structural demolition and subsequent repair work, reduces construction costs, and avoids damage to the integrity of the basement roof structure, thereby ensuring the safety performance of the building. At the same time, by arranging the lifting equipment outside the basement, the operating restrictions caused by the obstruction of multi-layer support beams, dense anti-floating anchor rods and bottom plate elevation differences in the basement are effectively avoided. There is no need to lower large lifting equipment to the basement floor, which completely solves the problems of collision between the equipment arm and the support beam and insufficient standing space.

[0095] Specifically, when the support 1 is lifted to a predetermined height using an external lifting mechanism 6 (such as a tower crane, a truck crane, etc.), the lifting point must be reasonably set according to the center of gravity position of the support 1 to ensure that the support 1 remains balanced during the lifting process and to avoid tilting or overturning. Before lifting, a comprehensive inspection of the braking system, wire rope 53, hook, etc. of the lifting mechanism is carried out to ensure that the equipment is in good operating condition. During the lifting process, a dedicated person is assigned to direct and maintain close communication with the lifting operator through communication equipment such as walkie-talkies, strictly controlling the lifting speed and height to avoid the support 1 colliding with the basement structure or other obstacles due to excessive speed or improper operation. After the support 1 is lifted to a predetermined height that is a certain distance above the basement roof, the lifting is suspended to prepare for the next step of adjusting the position.

[0096] Specifically, a ring chain 54 and a fall chain 55 are set on the support member 1, and the position of the support member 1 is adjusted in stages by gradually transferring the load. First, the support member 1 is connected to the temporary fixed point pre-set inside the basement through the ring chain 54, ensuring that the ring chain 54 is firmly connected and has a certain adjustment margin. Then, the wire rope 53 is slowly loosened to transfer part of the load to the ring chain 54. At this time, the stability and position change of the support member 1 are carefully observed. Next, the fall chain 55 is used to further fine-tune the horizontal and vertical positions of the support member 1 so that it gradually approaches the designed plane position. After each load transfer and position adjustment is completed, the stress conditions of each connecting component are checked. After confirming that there are no abnormalities, the corresponding wire rope 53 or fall chain 55 is released. Repeat the above operation until the support member 1 is accurately adjusted to the designed plane position through the fall chain 55, and the support member 1 is firmly fixed to the frame assembly 3 using high-strength bolts or welding to ensure that the connection strength meets the design requirements.

[0097] It should be noted that reference Figures 8 to 11 As shown, during the transportation of the support 1, transfer installation points need to be set up on both sides of the basement, and corresponding ring chains 54 and fall chains 55 need to be set up at the transfer installation points. It is preferred to select areas with stable structural force and easy operation as transfer installation points. A firm fixed bracket needs to be pre-installed at the transfer installation point to provide a reliable fulcrum for the ring chain 54 and the fall chain 55 to ensure that they can withstand the tension and gravity during the transfer of the support 1. When the support 1 is hoisted to the top of the transfer installation point on one side of the basement, the operator quickly connects the ring chain 54 to the support 1, and uses the fall chain 55 to fine-tune the angle and position of the support 1 so that part of the support 1 falls onto the support frame 31 first. Subsequently, the ring chain 54 and the fall chain 55 at the transfer installation point on the other side cooperate to alternately tighten and loosen the support 1 to slowly move horizontally along the predetermined path to the target installation area. During this process, the fall chain 55 continuously dynamically calibrates the position of the support 1 to ensure that it does not collide with obstacles such as pipelines inside the basement during transportation. After the support member 1 reaches the target position, the height and horizontal position are adjusted again with the help of the fall chain 55, and finally the support member 1 and the frame assembly 3 are firmly connected, completing the entire transportation and installation process.

[0098] Specifically, when dismantling the lifting equipment in sequence, first release the connection between the support 1 and the ring chain 54 and the fall chain 55, and then gradually remove the lifting components such as the wire rope 53 and the lifting ring 52. During the dismantling process, pay attention to protecting the basement structure to avoid structural damage due to the dismantling operation. After the dismantling is completed, the lifting hole is sealed. First, the debris and dust around the hole are cleaned, and then concrete with the same strength grade as the basement roof is used for pouring. During the pouring process, ensure that the concrete is vibrated and compacted to avoid quality defects such as honeycombs and holes. After the concrete reaches the designed strength, the sealed part is surface treated to make it consistent with the appearance of the surrounding roof structure, and the installation of the entire basement support device is completed.
