Description

Technical Field

[0001] The present invention belongs to the technical field of foundation support components, and in particular relates to a support component for preventing uneven settlement of indoor backfill soil. Background Art

[0002] In the field of construction engineering, the settlement of indoor backfill soil has always been a key problem affecting the stability and durability of ground structures. With the development of the construction industry, the functionality and use requirements of indoor spaces have continued to increase, and higher standards have been set for the stability of backfill foundations.

[0003] In traditional indoor backfill construction, factors such as uneven compaction of the backfill itself, natural settlement during soil consolidation, and the effects of external loads often lead to uneven settlement of the indoor floor, which in turn causes problems such as floor cracking. These problems not only affect the aesthetics and functionality of the interior, but in serious cases may also endanger the safety of the building structure and increase subsequent maintenance and repair costs.

[0004] At present, technicians have proposed some solutions and methods to the problem of indoor backfill settlement. For example, a certain support structure is used in the backfill area to enhance the bearing capacity and stability of the foundation. Among them, a more common idea is to press steel pipes into the backfill area in a plum blossom shape, tie steel mesh on the steel pipes, and then pour concrete, trying to avoid cracking of the concrete floor due to uneven settlement in this way. This method has played a supporting role for the backfill to a certain extent, and has achieved good results in some scenarios;

[0005] For example, in the prior art, the authorization announcement number is CN111809599B, the authorization announcement date is 2021.08.31, and the name is a foundation anti-settlement structure and construction method. This technology sequentially penetrates and inserts a concrete soil layer, a sand and gravel layer, and an anti-settlement concrete layer into the ground through the bottom end of a fixed column. A steel cage is placed on the upper surface of the concrete soil layer. Concrete is poured inside the steel cage. The foundation is fixed on the upper surface of the steel cage. Several anti-settlement devices are provided under the foundation to support the foundation. This application achieves the effect of effectively preventing the foundation from settling.

[0006] However, the existing technology still has some shortcomings in practical applications. The combination of fixed columns and steel cages only enhances the support for concrete from a two-dimensional top-down perspective, and its support effect needs to be further optimized. Therefore, in order to overcome the above-mentioned defects in the existing technology, through improvements and innovations on the existing technology, a support assembly for preventing uneven settlement of indoor backfill soil is proposed, which can more effectively prevent settlement of indoor backfill soil. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a support assembly for preventing uneven settlement of indoor backfill soil, which can overcome the above problems or at least partially solve the above problems.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a support component for preventing uneven settlement of indoor backfill soil, including a plurality of steel pipes arranged vertically and distributed in a mesh shape, and also including: a steel cage mesh horizontally arranged between the plurality of said steel pipes; the ends of adjacent said steel pipes are connected by rope 1; a horizontal pipe horizontally arranged between adjacent said steel pipes, said horizontal pipe is close to the top of the steel pipe, and said rope 1 passes over the top of the horizontal pipe; rope 2 is horizontally connected between the steel pipe and rope 1; a three-dimensional support network is formed between rope 1, rope 2 and the steel pipe, horizontal pipe and steel cage mesh.

[0009] Preferably, the rope 1 and the transverse tube form an inverted V shape.

[0010] Furthermore, the end of the horizontal pipe is provided with a collar, and the collar is sleeved on the steel pipe.

[0011] Furthermore, it also includes a support plate connected to the horizontal tube, vertical rods are symmetrically fixedly connected to the support plate, and horizontal rods are horizontally inserted on the vertical rods.

[0012] Preferably, a movable slot is provided on the vertical rod, and the horizontal rod is horizontally inserted into the vertical rod through the movable slot. One end of two adjacent vertical rods is connected to a rope three, and the rope three passes through the bottom of the horizontal tube.

[0013] Furthermore, it also includes rope four, which forms an M-shaped support network between rope two, the vertical rod and the horizontal tube.

[0014] Preferably, the two ends of the rope four are respectively connected to the rope two on both sides of the horizontal tube, wherein the rope four located between the rope two and the horizontal tube passes through the end of the horizontal bar away from the rope three, so that the rope four forms an M-shaped support net between the rope two, the vertical bar and the horizontal tube.

[0015] Preferably, a triangle area 1 is formed between the rope 1, the rope 2 and the steel pipe, and a triangle area 2 is formed between the rope 4 and the rope 2.

[0016] Preferably, a positioning groove is provided on the support plate, the rope 1 is located in the positioning groove, a connecting block is provided at the connection between the rope 1 and the rope 2, and the volume of the connecting block is larger than the width of the positioning groove.

[0017] Preferably, positioning pins are provided on both sides of the horizontal rod and the vertical rod.

[0018] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0019] 1. This support component for preventing uneven settlement of indoor backfill soil provides initial bearing capacity through the set basic support frame (steel pipe + steel cage mesh). The three-dimensional support network (steel pipe + rope 1 + rope 2 + cross pipe) converts single-point loads into plane loads. The multi-dimensional support structure (vertical rod + cross rod + rope 3 + rope 4) further expands the plane load to three-dimensional space, forming a four-level bearing system of "point-line-surface-body". When the backfill soil settles, the settlement is effectively dispersed throughout the support area, avoiding local cracking and improving the anti-settlement effect.

[0020] 2. The support components for preventing uneven settlement of indoor backfill soil are designed with inverted V-shaped and M-shaped support nets, which can respond to soil settlement and deformation in real time. When slight local settlement occurs, ropes 1, 2, 3 and 4 absorb energy through elastic deformation. At the same time, the structures of triangle area 1 and triangle area 2 limit the development of deformation, further improving the anti-settlement effect.

[0021] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0034] The following is combined with Figure 1 -Attached Figure 9 , describes in detail the technical solutions provided by each embodiment of the present invention.

[0035] Example: Refer to Figures 1-9 A support assembly for preventing uneven settlement of indoor backfill soil comprises a plurality of vertically arranged steel pipes 1 and a steel cage mesh horizontally arranged between the plurality of steel pipes 1; the ends of adjacent steel pipes 1 are connected by ropes 11; a horizontal pipe 2 is arranged horizontally between the adjacent steel pipes 1, the horizontal pipe 2 being close to the top of the steel pipe 1, and the rope 11 passing over the top of the horizontal pipe 2; and a rope 2 12 is horizontally connected between the steel pipe 1 and the rope 1 11. Ropes 11 12 and the steel pipes 1, the horizontal pipe 2, and the steel cage mesh form a three-dimensional support network. Ropes 11 12 and 12 are made of steel cables or high-strength polyester fiber bundles, exhibiting strong tensile strength. When steel cables are used, they are treated with corrosion resistance. Rope 11 and the horizontal pipe 2 form an inverted V-shape.

[0036] When the device is in use, the indoor backfill area is interlaced in a mesh shape, and a number of steel pipes 1 are vertically pressed into the plum blossom shape 6. The steel pipes 1 are inserted into the original foundation to a depth of ≥500mm, and are exposed 100-150mm from the backfill surface. The horizontal and vertical spacing is 800-1200mm (which can be changed according to actual requirements). The horizontally arranged steel cage is tied to the top of the steel pipe 1, using 6mm-8mm diameter steel bars with a spacing of 150mm×150mm, and fixed to the steel pipe 1 by wire.

[0037] The ends of adjacent steel pipes 1 are connected by ropes 11. Transverse pipes 2 are horizontally positioned below the tops of adjacent steel pipes 1. Collars 24 are installed at both ends of the transverse pipes 2 (the collars 24 can be provided with a plug at one end, which is then inserted into the transverse pipe 2, or the collars 24 can be welded to the transverse pipe 2). A gap of 2-3 mm is provided between the collars 24 and the steel pipes 1 to ensure that the transverse pipes 2 can be rotated around the steel pipes 1 for adjustment. Ropes 11 pass over the transverse pipes 2, forming an inverted V-shaped structure.

[0038] Rope 2 12 is horizontally connected between steel pipe 1 and rope 1 11 to form a triangular area 4, which utilizes the stability of the triangle to enhance the structure's ability to resist lateral displacement.

[0039] When the backfill soil settles, steel pipe 1, as a vertical support column, first bears the downward pressure of the soil. At this time, the inverted V-shaped structure formed by rope 11 and cross pipe 2 acts like a tension tripod, converting the horizontal displacement of the top of steel pipe 1 into the tension of rope 11. The oblique tension of the inverted V-shape offsets part of the horizontal force. At the same time, when the backfill soil settles, the steel pipe 1 settles together. Due to the design of rope 11 bypassing cross pipe 2 from above, a force is generated to pull cross pipe 2 downward. Because cross pipe 2 is laid horizontally on the backfill soil, it has a large contact area and a large span with the backfill soil. Therefore, cross pipe 2 provides support for the settlement of backfill soil and steel pipe 1, effectively preventing significant settlement.

[0040] Furthermore, a ring 24 is provided at the end of the transverse tube 2, and the ring 24 is sleeved on the steel tube 1; a connecting plate 13 is welded on the outer periphery near the top end of the steel tube 1. Since adjacent steel tubes 1 are connected to each other through the ring 24 on the transverse tube 2, when the steel tube 1 and the backfill soil settle, the downward pulling force of the rope 11 on the transverse tube 2 will be transmitted to other steel tubes 1. Since the connecting plate 13 increases the contact area between the steel tube 1 and the backfill soil, the tensile performance of the transverse tube 2 is improved, thereby further improving the anti-settlement effect.

[0041] Rope 2 12 connects the steel pipe 1 and rope 1 11 to form a triangular area 4. The stability of the triangle is used to limit the lateral deformation of the steel pipe 1. Therefore, when the backfill soil settles unevenly and the steel pipe 1 tends to settle, rope 2 12 exerts its lateral deformation performance, so that the load is dispersed and transmitted through the path of steel pipe 1, rope 2 12, rope 1 11, and adjacent steel pipes 1, avoiding a single steel pipe 1 from bearing concentrated loads and further avoiding uneven settlement.

[0042] Therefore, compared with the existing technology, this device connects adjacent steel pipes 1 through ropes 11 and connects several steel pipes 1 through steel cages, and uses cross pipes 2 to disperse the force of steel pipes 1, and then uses the rings 24 on the cross pipes 2 to connect adjacent steel pipes 1, forming mutual constraints, so that when the steel pipes 1 settle due to backfill soil, the settlement force can be effectively dispersed by ropes 11, avoiding uneven settlement causing ground cracks, and at the same time forming a three-dimensional support network, effectively improving the anti-settlement effect.

[0043] In some embodiments, a support plate 21 connected to the transverse tube 2 is further included. Vertical rods 3 are symmetrically fixedly connected to the support plate 21 , and transverse rods 31 are horizontally inserted into the vertical rods 3 .

[0044] On the one hand, the setting of the support plate 21 can maintain a certain distance between the cross pipe 2 and the backfill soil, making it convenient for the rope 11 to pass through from under the cross pipe 2. On the other hand, the support plate 21 can increase the contact area between the cross pipe 2 and the backfill soil, and improve the anti-pull-down performance of the cross pipe 2. In addition, a clamp 20 is provided on the support plate 21, and the cross pipe 2 is connected to the support plate 21 through the clamp 20, which is convenient for installation.

[0045] The arrangement of the vertical rods 3 enables the vertical rods 3 to be placed vertically in the concrete when the concrete floor is poured, so as to improve the anti-settling performance of the concrete floor.

[0046] In some embodiments, a movable slot 32 is provided on the vertical rod 3, and the horizontal rod 31 is horizontally inserted into the vertical rod 3 through the movable slot 32. One end of two adjacent vertical rods 3 is connected to a rope three 34, and the rope three 34 passes under the horizontal tube 2.

[0047] When the ground settles, the settlement of the steel pipe 1 will produce a downward pulling force on the horizontal pipe 2. Since the horizontal rod 31 and the vertical rod 3 are combined with the concrete, the set rope three 34 can provide a lifting force for the horizontal pipe 2 when the horizontal pipe 2 is subjected to the downward pulling force, thereby offsetting part of the displacement caused by the settlement.

[0048] In some embodiments, ropes 35 are further included. Ropes 35 form an M-shaped support network 51 between ropes 12, vertical rods 3, and transverse tubes 2. Ropes 35 are connected at both ends to ropes 12 on either side of transverse tube 2. Ropes 35 located between ropes 12 and transverse tube 2 pass through the end of transverse rod 31 away from ropes 34, forming an M-shaped support network 51 between ropes 12, vertical rods 3, and transverse tube 2. Triangles 11, 12, and steel tube 1 form triangles 4, while triangles 5 form between ropes 35 and ropes 12.

[0049] The M-shaped support mesh 51 formed by ropes 35 acts as an elastic buffer layer, absorbing settlement energy through deformation while simultaneously transferring the load to the surrounding support structure, achieving a synergistic effect of local settlement and overall regulation. The triangular area 5 formed between ropes 35 and ropes 12 further enhances the anti-settlement performance of the steel pipe 1.

[0050] A positioning groove 22 is provided on the support plate 21 , and the rope 1 11 is located in the positioning groove 22 . A connecting block 23 is provided at the connection between the rope 1 11 and the rope 2 12 , and the volume of the connecting block 23 is larger than the width of the positioning groove 22 .

[0051] The cooperation between the positioning groove 22 and the connecting block 23 ensures that the rope 11 will not slip off the support plate 21 under the action of load, thereby maintaining the stability of the inverted V-shaped structure. At the same time, when one side of the steel pipe 1 sinks, the rope 11 is pulled, and when the connecting block 23 is located at the support plate 21, it is blocked and cannot pass through the positioning groove 22, so that the settlement amplitude of the steel pipe 1 on one side is restricted, thereby effectively improving the effect of uneven settlement.

[0052] The cross bar 31 is provided with positioning pins 33 on both sides of the vertical bar 3. The positioning pins 33 lock the cross bar 31 laterally, which can prevent the cross bar 31 from shifting when the load changes, ensuring that the geometric shape of the M-shaped support net 51 remains unchanged, thereby continuously playing a lateral supporting role. This design ensures the overall stability of the structure while allowing coordinated deformation within a certain range, avoiding stress concentration caused by rigid connection.

[0053] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the present invention can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
