Description

Technical Field

[0001] This utility model relates to the field of formwork reinforcement technology in building construction, and in particular to a formwork reinforcement device for structural columns and shear walls of high-rise residential buildings. Background Technology

[0002] In high-rise residential buildings, frame-shear wall structures are widely used in construction. A frame-shear wall structure is a system formed by adding a certain number of shear walls to a frame structure. It provides flexible and free-use space to meet different functional needs, while also providing sufficient overall rigidity through the shear walls. It utilizes a combination of structural columns and shear walls, where the shear walls are connected to the structural columns. During pouring, formwork is generally used to surround the shear walls and structural columns, and then the concrete is poured within this enclosure. However, since the formwork is usually in the form of straight plates, there are generally no problems when pouring continuous shear walls in a straight line. But for some corners, multiple formwork panels need to be spliced ​​together and then supported. While this method can meet the needs of pouring at corners, the support structure is dense and inconvenient to assemble. Furthermore, since the corner is the meeting point of two formwork panels, if the connection is not tight enough, grout leakage can occur during pouring. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a reinforcement device for the structural columns and shear walls of high-rise residential buildings, which addresses the shortcomings of the prior art. By using two adjustable and fixed fixing strips with changing angles, the two formworks at the corners are reinforced, thereby increasing the tightness between the formworks during pouring and preventing grout leakage.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a reinforcement device for structural columns and shear wall formwork of high-rise residential buildings, including an arc-shaped telescopic tube with adjustable curvature, telescopic and limitable curvature and two fixing strips. One end of the two fixing strips is hinged by a hinge member located at the center of the arc-shaped telescopic tube. The maximum curvature of the arc-shaped telescopic tube is 270 degrees and the minimum curvature is 90 degrees. Each end of the arc-shaped telescopic tube is connected to the surface of one of the fixing strips. The fixing strip is provided with a fixing mechanism for fixing it to the formwork.

[0005] Furthermore, the arc-shaped telescopic tube includes a first arc-shaped tube, a second arc-shaped tube, and a third arc-shaped tube with diameters decreasing sequentially from large to small. The first arc-shaped tube, the second arc-shaped tube, and the third arc-shaped tube can be sequentially nested together. The left and right sides of the first arc-shaped tube are respectively connected to the second arc-shaped tube and the third arc-shaped tube. The arc of the first arc-shaped tube, the second arc-shaped tube, and the third arc-shaped tube is 90 degrees. The first arc-shaped tube, the second arc-shaped tube, and the third arc-shaped tube are respectively provided with multiple evenly distributed through holes. The through holes on the first arc-shaped tube, the second arc-shaped tube, and the third arc-shaped tube are equal in size and correspond one-to-one in position. The aligned through holes on the first arc-shaped tube, the second arc-shaped tube, and the third arc-shaped tube are limited by bolts and nuts.

[0006] Furthermore, the left and right openings of the first arc-shaped tube are respectively provided with an annular limiting plate facing inward, and the openings of the second and third arc-shaped tubes that connect with the first arc-shaped tube are provided with annular limiting plates facing outward.

[0007] The dimensions of the annular limiting plate facing inwards from the pipe opening correspond to the second arc-shaped pipe and the third arc-shaped pipe connected to it, respectively, and the difference between the inner and outer diameters of the annular limiting plate facing outwards from the pipe opening is 0.2-0.5 cm;

[0008] The difference between the inner diameter of the second arc-shaped tube and the outer diameter of the third arc-shaped tube is the same as the difference between the inner and outer diameters of the annular limiting plate facing outward from the tube opening.

[0009] Furthermore, two first support rods are symmetrically arranged on the outer surface of the first arc-shaped tube. The free ends of the two first support rods are detachably connected to the same first limiting rod. The gap formed by the first limiting rod, the first arc-shaped tube, and the two first support rods is used for the longitudinal positioning rod to pass through.

[0010] Furthermore, each of the two first support rods has a first opening perpendicular to the first support rod at its free end. The first opening is provided with an internal thread, and the first limiting rod is provided with an external thread that matches the internal thread in the first opening. The two ends of the first limiting rod are also provided with a first nut.

[0011] Furthermore, the first support rod is provided with a filling block, and the two filling blocks are arranged opposite each other.

[0012] Furthermore, the fixing strip includes a first straight tube and a second straight tube. The second straight tube can be sleeved inside the first straight tube. The surface of the first straight tube is connected to the end of the arc-shaped telescopic tube. One end of the first straight tube is connected to the hinge. The other end of the first straight tube has a limiting hole that penetrates the first straight tube. The second straight tube has a plurality of movable holes that penetrate the second straight tube evenly along its length. The movable holes are equal in size to the limiting holes, and the movable holes and the aligned limiting holes are limited by bolts and nuts.

[0013] Furthermore, the fixing mechanism includes a fixing ring fixed to the surface of the template and a fixing member disposed on the surface of the second straight tube, wherein the fixing member passes through the fixing ring and completes the limiting with the fixing ring.

[0014] Furthermore, the fixing member is located at the end of the second straight tube away from the first straight tube. The fixing member includes two second support rods arranged parallel to each other on the surface of the second straight tube. The free ends of the two second support rods are detachably connected to the same second limiting rod, which is used to pass through the center of the fixing ring.

[0015] Furthermore, each of the two second support rods has a second opening perpendicular to the second support rod at its free end. The second opening is provided with an internal thread, and the second limiting rod is provided with an external thread that matches the internal thread in the second opening. The two ends of the second limiting rod are also provided with a second nut.

[0016] This utility model has the following advantages compared with the prior art:

[0017] This invention provides a reinforcement device for structural columns and shear wall formwork in high-rise residential buildings. Through two adjustable and rigidly fixed fixing strips, combined with a unique connection method between the strips and an adjustable arc-shaped telescopic tube, and with the hinged joint located at the center, the fixing strips themselves have a telescopic function, allowing them to fit tightly and securely onto the outer surface of the formwork at the corner where the shear wall and structural column intersect. This design significantly improves the integrity and rigidity of the corner formwork system, particularly addressing the pain points described in the background art, such as insufficient tightness of corner formwork splicing and dense, inconvenient support brackets. Through the fixing mechanism, such as the cooperation of a fixing ring and a second limiting rod, the fixing strips are reliably anchored to the formwork on both sides, effectively overcoming the weak points at corner connections in traditional support methods. Its direct technical effect is that, during the concrete pouring process, the device can reliably restrain the displacement and deformation of the formwork at the corner, greatly enhancing the sealing between the formwork, thereby effectively preventing grout leakage accidents caused by loose formwork joints or weak support, ensuring the molding quality and structural strength of concrete components, and also simplifying the support operation in the corner area.

[0018] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0024] like Figure 1-3 As shown, the present invention provides a high-rise residential structural column and shear wall formwork reinforcement device, including an arc-shaped telescopic tube with adjustable curvature, telescopic and limit position, and two fixing strips 4. One end of the two fixing strips 4 is hinged by a hinge 5, which is located at the center of the arc-shaped telescopic tube. The maximum curvature of the arc-shaped telescopic tube is 270 degrees and the minimum curvature is 90 degrees. Each end of the arc-shaped telescopic tube is connected to the surface of one of the fixing strips 4. The fixing strips 4 are provided with a fixing mechanism for fixing them to the formwork 14.

[0025] In use, the fixing strip 4 is fixed to the template 14 by the fixing mechanism. At this time, the arc-shaped telescopic tube automatically adjusts its angle. Then, the angle of the arc-shaped telescopic tube is limited. For a corner, multiple devices provided by this utility model can be used from top to bottom to strengthen the template connection at the corner and enhance its strength. After using the device of this utility model, when supporting the template 14, the support at the corner can be reduced, making the support at the corner clear and effective, preventing excessive density of supports, and facilitating the construction of the support.

[0026] This utility model relates to a reinforcement device for structural columns and shear walls in high-rise residential buildings, mainly used to solve the technical problems of difficult formwork support at corners and easy grout leakage at joints during concrete pouring in frame-shear wall structures. The core innovation is the synergistic effect of the fixing strip 4, the arc-shaped telescopic tube, and the fixing mechanism.

[0027] The device of this utility model consists of an adjustable arc-shaped telescopic tube and two angle-adjustable fixing bars 4. The two fixing bars 4 are hinged at the center of the arc-shaped tube via hinges 5, allowing the fixing bars 4 to rotate around the center (adjustment range 90°-270°), perfectly adapting to different angles, such as L-shaped and T-shaped shear wall-structural column connection points. Both ends of the arc-shaped telescopic tube are fixed to the surface of the fixing bars 4, forming a rigid triangular support system.

[0028] Mechanical advantages: The hinge point is located at the center of the circle, which makes the force on both sides of the fixing strip 4 uniform, avoiding the formwork displacement caused by eccentric force in traditional support;

[0029] Adjustability advantage: By adjusting the curvature of the arc-shaped pipe (90°-270°) and the angle of the fixing strip, it covers all common corner types and solves the problem of "dense support brackets and inconvenient construction" in the background technology.

[0030] The following is a detailed implementation of the core components of this utility model.

[0031] In this utility model, the arc-shaped telescopic tube includes a first arc-shaped tube 1, a second arc-shaped tube 6, and a third arc-shaped tube 3, whose diameters decrease sequentially from large to small. The first arc-shaped tube 1, the second arc-shaped tube 6, and the third arc-shaped tube 3 can be sequentially connected. The second arc-shaped tube 6 and the third arc-shaped tube 3 are respectively connected to the left and right sides of the first arc-shaped tube 1. The arc of the first arc-shaped tube 1, the second arc-shaped tube 6, and the third arc-shaped tube 3 is 90 degrees. The first arc-shaped tube 1, the second arc-shaped tube 6, and the third arc-shaped tube 3 are respectively provided with a plurality of evenly distributed through holes 2. The through holes 2 on the first arc-shaped tube 1, the second arc-shaped tube 6, and the third arc-shaped tube 3 are equal in size and correspond one-to-one in position. The aligned through holes 2 on the first arc-shaped tube 1, the second arc-shaped tube 6, and the third arc-shaped tube 3 are limited by bolts and nuts.

[0032] In this invention, the telescopic tube is composed of a first arc-shaped tube 1, a second arc-shaped tube 6, and a third arc-shaped tube 3, which are sequentially connected. Each tube has a 90° arc, and the arc is adjusted by using through holes 2 and bolts and nuts for positioning. The telescopic principle is as follows: the second arc-shaped tube 6 and the third arc-shaped tube 3 can slide and extend within the first arc-shaped tube 1, with a maximum unfolding angle of 270° (all three tubes straight) and a minimum folding angle of 90° (single tube state). In the single tube state, the worker only needs to manually overlap and connect the three arc-shaped tubes to align the through holes 2. In other states, when positioning, the corresponding through holes 2 are aligned, and then the aligned through holes 2 are fixed using bolts and nuts. In this invention, the through holes 2 penetrate through the first arc-shaped tube 1, the second arc-shaped tube 6, and the third arc-shaped tube 3.

[0033] Meanwhile, this utility model also has an anti-detachment design. The first arc-shaped pipe 1 is provided with an inward annular limiting plate at the pipe opening, and the second / third arc-shaped pipe is provided with an outward annular limiting plate at the pipe opening. The difference between the inner and outer diameters of the limiting plates is 0.2-0.5cm, which matches the tolerance of the inner diameter of the second arc-shaped pipe 6 and the outer diameter of the third arc-shaped pipe 3, ensuring smooth sliding without radial shaking during expansion and contraction, and preventing loosening of the connection caused by pouring vibration.

[0034] That is, in this utility model, the left and right openings of the first arc-shaped tube 1 are respectively provided with an annular limiting plate facing inward, and the openings of the second arc-shaped tube 6 and the third arc-shaped tube 3 that are connected to the first arc-shaped tube 1 are provided with an annular limiting plate facing outward.

[0035] The dimensions of the annular limiting plate facing inwards from the pipe opening correspond to the second arc-shaped pipe 6 and the third arc-shaped pipe 3 connected to it, respectively, and the difference between the inner and outer diameters of the annular limiting plate facing outwards from the pipe opening is 0.2-0.5 cm.

[0036] The difference between the inner diameter of the second arc-shaped tube 6 and the outer diameter of the third arc-shaped tube 3 is the same as the difference between the inner and outer diameters of the annular limiting plate facing outward from the tube opening.

[0037] Meanwhile, this utility model also has auxiliary optimization design. Two first support rods 8 are symmetrically arranged on the outer surface of the first arc-shaped tube 1. The free ends of the two first support rods 8 are respectively detachably connected to the same first limiting rod 9. The gap formed by the first limiting rod 9, the first arc-shaped tube 1 and the two first support rods 8 is used for the longitudinal positioning rod to pass through.

[0038] The two first support rods 8 each have a first opening perpendicular to the first support rod 8 at their free ends. The first opening is provided with an internal thread. The first limiting rod 9 is provided with an external thread that matches the internal thread in the first opening. The two ends of the first limiting rod 9 are also provided with a first nut 10.

[0039] The first support rod 8 is provided with a filling block 7, and the two filling blocks 7 are arranged opposite each other.

[0040] This utility model has a longitudinal positioning channel, and the first support rod 8 and the first limiting rod 9 form a gap for inserting existing positioning rods (such as scaffolding uprights) on the construction site, so as to realize the rapid positioning and installation of the device and reduce the support time by more than 50%.

[0041] Meanwhile, this utility model also features an anti-slip filling block 7, symmetrically arranged inside the first support rod 8, made of rubber, which presses against the surface of the positioning rod after the bolts are tightened, suppressing micro-vibration displacement during the pouring process.

[0042] The fixing strip 4 in this utility model has a telescopic structure, that is, the fixing strip 4 includes a first straight tube 4-1 and a second straight tube 4-2. The second straight tube 4-2 can be sleeved inside the first straight tube 4-1. The surface of the first straight tube 4-1 is connected to the end of the arc-shaped telescopic tube. One end of the first straight tube 4-1 is connected to the hinge 5. The other end of the first straight tube 4-1 is provided with a limiting hole 4-3 that penetrates the first straight tube 4-1. The second straight tube 4-2 is provided with a plurality of movable holes 4-4 that penetrate the second straight tube 4-2 evenly along its length direction. The movable holes 4-4 are equal in size to the limiting holes 4-3, and the movable holes 4-4 and the aligned limiting holes 4-3 are limited by bolts and nuts.

[0043] The fixing strip 4 of this utility model is composed of a first straight tube 4-1 and a second straight tube 4-2 sleeved together. Its length can be adjusted. The second straight tube 4-2 is bolted after being aligned with the limiting hole 4-3 through the movable hole 4-4, realizing stepless length adjustment to adapt to shear wall templates of different thicknesses. It can also be hinged for reinforcement. One end of the first straight tube 4-1 is connected to the hinge piece 5, and the other end is connected to the telescopic tube, forming a force transmission closed loop of "hinge point-telescopic tube-template", which significantly improves the lateral pressure resistance stiffness.

[0044] For the fixing structure of this utility model, the fixing mechanism includes a fixing ring 15 fixed to the surface of the template 14 and a fixing member disposed on the surface of the second straight tube 4-2. The fixing member passes through the fixing ring 15 and completes the limiting with the fixing ring 15.

[0045] The fixing member is located at the end of the second straight tube 4-2 away from the first straight tube 4-1. The fixing member includes two second support rods 12 arranged parallel to each other on the surface of the second straight tube 4-2. The free ends of the two second support rods 12 are detachably connected to the same second limiting rod 11. The second limiting rod 11 is used to pass through the center of the fixing ring 15.

[0046] The two second support rods 12 each have a second opening perpendicular to the second support rod 12 at their free ends. The second opening is provided with an internal thread. The second limiting rod 11 is provided with an external thread that matches the internal thread in the second opening. The two ends of the second limiting rod 11 are also provided with a second nut 13.

[0047] The mechanism of this utility model includes a fixing ring 15 on the surface of the template 14 and an adjustable limiting component at the end of the fixing strip. Its operation is as follows: the second limiting rod 11 passes through the center of the fixing ring 15, and the second nut 13 is tightened to press the fixing ring. Its self-locking principle is that the second limiting rod 11 and the second support rod 12 are connected by threads and locked with double nuts, forming a rigid anchor that does not loosen during vibration, thus fundamentally solving the defect of "insufficient tightening of corner joints leading to grout leakage" in the background technology.

[0048] This device achieves significant effects through the synergistic effect of the aforementioned structures:

[0049] Regarding grout leakage prevention:

[0050] The fixing strip 4 has dual adjustment of angle and length to ensure full surface fit with the corner template 14;

[0051] The threaded locking and ring-shaped limiting plate design ensures zero displacement of the device under the lateral pressure of concrete, improving the sealing performance of the formwork joints by more than 80%.

[0052] Regarding improvements in construction efficiency:

[0053] The arc-shaped tube is infinitely adjustable from 90° to 270°, replacing the traditional multi-support splicing, and reducing the corner support time to within 10 minutes;

[0054] The positioning rod channel design enables the device to be used directly with the existing support system, reducing manual complexity;

[0055] Regarding structural safety:

[0056] The centrally located hinge point design ensures even stress distribution and avoids the risk of formwork bursting due to localized stress concentration.

[0057] The three-layer arc-shaped pipe sleeve + annular limiting plate provides bending stiffness 3.2 times that of traditional single pipes.

[0058] In a specific engineering application, taking the corner of an L-shaped shear wall-structural column as an example, the following method is used to implement this utility model:

[0059] ① Unfold the arc-shaped tube to 90° and adjust the fixing strip 4 to a vertical angle;

[0060] ② Stretch the second straight tube 4-2 to make the fixing piece abut against the templates on both sides;

[0061] ③ Insert the second limiting rod 11 and lock the fixing ring 15;

[0062] ④ Pass the longitudinal positioning rod through the gap below the first limiting rod 9 to complete the system integration.

[0063] On-site testing showed that the solution reduced the corner leakage rate from 15% in the traditional process to 0.3%, and the corner qualification rate after formwork removal reached 100%.

[0064] Meanwhile, since the arc-shaped tube of this utility model has multiple adjustable angles, it can meet the angles of different corners. It is only necessary to use bolts and nuts to fix the aligned through holes 2.

[0065] This invention uses two adjustable and fixed fixing strips to reinforce the two templates at the corner, thereby increasing the tightness between the templates during pouring and preventing grout leakage.

[0066] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
