Description

Technical field

[0001] The invention relates to a type of reinforcing device, in particular a corner reinforcement kit for reinforcing building corners. Prior technology

[0002] In construction projects, doors and windows in buildings are an indispensable part. In the construction process of high-rise buildings or general residences, the construction of walls usually involves first erecting a reinforced skeleton, then pouring concrete into it and solidifying it to form the main structure of the building. The door and window openings are then cut or reserved during subsequent construction stages, especially in the areas located at the four corners of doors and windows, which are often stress concentration points that are prone to cracks or structural deformation over a long period of time or under the influence of external forces.

[0003] Further, during the service life of the building, these stress concentration points are gradually affected by earthquakes, temperature changes, floor loading changes, and the aging of the building materials. For example, in the event of an earthquake, the building structure is subjected to dynamic stresses from the earthquake, resulting in possible deformation or damage to the corners of doors and windows. In addition, with the growth of building age, long-term moisture penetration and temperature changes, which may lead to expansion or contraction of concrete and reinforcement materials, resulting in cracks, thereby affecting the durability and overall safety of the building structure.

[0004] To improve the structural strength of building door and window corners, Xizhi technology usually provides corner reinforcement kits at door and window corners to provide additional support, disperse stress and reduce stress concentration effects, thereby improving the shock resistance and durability of door and window structures. However, in the construction of high-rise buildings, reinforcement kits need to be installed at the door and window corners of each floor, so the corner reinforcement kits must have good construction adaptability and installation convenience.

[0005] For example, these corner reinforcement kits need to consider the convenience of transportation and on-site installation, which may affect transportation efficiency and increase construction difficulty if the volume is too large or the structure is too complex. Then, the size of the reinforcement kit also needs to be able to accommodate door and window openings of different specifications. In addition, corner reinforcement kits still need to have sufficient strength and stiffness to ensure that they can effectively reinforce corner structures under earthquake or long-term loads, reducing the risk of deformation or damage and further improving the durability and safety of the building.

[0006] Therefore, it is necessary to provide a corner reinforcement kit to address the problems in the existing technology caused by inconvenient installation, inadequate dimensional adaptability, or poor structural strength. Contents of the invention

[0007] In view of this, the present invention provides a corner reinforcement kit for reinforcing a building corner. The corner reinforcement kit includes a plurality of main reinforcing bars, a plurality of first surrounding members, and a second surrounding member. Each main reinforcing bar includes a bent portion and two extensions connecting the bent portion. The bent portions of the main reinforcing bars are arranged in parallel to form a corner structure, which is used to be placed in the building corner. Each first surrounding member is used to fit onto the extension of the main reinforcing bar to fix the main reinforcing bar in a relative position. The second surrounding member is disposed in the corner structure, and the second surrounding member is surrounded by the bent portion of the main reinforcing bar and tightly abuts against the bent portion.

[0008] The corner reinforcement kit further includes a U-shaped corner bracket, which is secured to the second surrounding member.

[0009] The arc portion of the U-shaped corner frame is coupled to multiple first main reinforcement bars in the main reinforcement bars.

[0010] The second surrounding member is smaller than the first surrounding member. Both the first and second surrounding members are spiral stirrups.

[0011] The outer diameter of the second surrounding member gradually increases from one end to the other.

[0012] The present invention also provides a method for manufacturing a corner reinforcement kit, comprising the following steps: preparing a plurality of main reinforcing bars, a plurality of first surrounding members, and a second surrounding member, wherein each main reinforcing bar includes a bent portion and two extensions connecting the bent portion; arranging the bent portions of the main reinforcing bars in parallel to form a corner structure; fitting each first surrounding member onto the extension of the main reinforcing bar to fix the main reinforcing bar in a relative position; and placing the second surrounding member in the corner structure such that the second surrounding member is surrounded by the bent portion of the main reinforcing bar and closely abuts against the bent portion.

[0013] The method further includes the following steps: preparing a U-shaped corner frame; and fitting a second surrounding member onto the U-shaped corner frame. The step of placing the second surrounding member within the corner structure is further subdivided into the following steps: placing the U-shaped corner frame and the second surrounding member within the corner structure.

[0014] The arc portion of the U-shaped corner frame is coupled to multiple first main reinforcement bars in the main reinforcement bars.

[0015] The second surrounding member is smaller than the first surrounding member. Both the first and second surrounding members are spiral stirrups.

[0016] The outer diameter of the second surrounding member gradually increases from one end to the other.

[0017] In summary, this invention provides a corner reinforcement kit that uses a first surrounding member to fix the relative positions of the main reinforcing bars, ensuring the structural stability of the corner reinforcement kit. Furthermore, the second surrounding member provides support at the bend, further effectively dispersing local stress at the building corner, thereby reducing the risk of damage caused by stress concentration. In practice, the corner reinforcement kit of this invention is easy to assemble and transport, making it more convenient for on-site assembly or direct use. Furthermore, since the corner reinforcement kit of this invention uses the first surrounding member to fit over both ends of the main reinforcing bars to fix the distance between each main reinforcing bar, in practical applications, the size of the corner reinforcement kit can be adjusted according to the actual thickness of the corner in each building to meet different size requirements. Therefore, the corner reinforcement kit of this invention can effectively solve the problems caused by inconvenient installation, insufficient size adaptability, or poor structural strength in the prior art, thereby improving the reinforcement effect of door and window corners and ensuring the seismic resistance and long-term stability of buildings.

[0025] To make the advantages, spirit, and features of the present invention easier and clearer to understand, detailed descriptions and discussions will follow with reference to specific embodiments and the accompanying drawings. It should be noted that these specific embodiments are merely representative examples of the present invention, and the specific methods, apparatus, conditions, materials, etc., exemplified are not intended to limit the present invention or the corresponding specific embodiments.

[0026] In the description of this specification, references to terms such as "one specific embodiment," "another specific embodiment," or "partial specific embodiment" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment is included in at least one embodiment of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments.

[0027] Please refer to Figure 1, which is a schematic diagram illustrating a corner reinforcement kit 1 according to a specific embodiment of the present invention. As shown in Figure 1, the corner reinforcement kit 1 of this specific embodiment includes a plurality of main reinforcing bars 11, a plurality of first surrounding members 12, and a second surrounding member 13. Each main reinforcing bar 11 includes a bent portion 111 and two extension portions 112 connecting the bent portion. The bent portions 111 of the main reinforcing bars 11 are arranged in parallel to form a corner structure, which is used to be placed in the corner of a building. Each first surrounding member 12 is used to fit onto the extension portion 112 of the main reinforcing bar 11 to fix the main reinforcing bar 11 in a relative position. The second surrounding member 13 is disposed in the corner structure, and the second surrounding member 13 is surrounded by the bent portion 111 of the main reinforcing bar 11 and closely abuts against the bent portion 111.

[0028] In this specific embodiment, the main rib 11, the first surrounding member 12, and the second surrounding member 13 of the corner reinforcement kit 1 can be made of high-strength steel with heat treatment or electroplating anti-corrosion treatment to ensure that the corner reinforcement kit 1 has sufficient rigidity and durability. In practice, the entire main rib 11 can be bent at approximately 90° to form an L-shaped structure, as shown in Figure 1. The corner of the L-shaped structure of the main rib 11 is the bent portion 111, and the two ends of the bent portion 111 extend to form extension portions 112. In this specific embodiment, the number of main ribs is 4, and the bent portions 111 of each main rib 11 are arranged in parallel with each other, that is, the main ribs 11 are arranged in a quadrilateral cross-section, so that the bent portions 111 of the arranged main ribs 11 form a one-corner structure. At this point, the corner reinforcement kit 1 includes an inner main reinforcement bar 11 (i.e., the shorter main reinforcement bar 11 in Figure 1) and an outer main reinforcement bar 11 (i.e., the longer main reinforcement bar 11 in Figure 1). The corner structure can be installed in the building corner. In practical applications, the building corner can be at the corner of a door or window. The corner of the corner structure of the main reinforcement bar 11 can correspond to the angle of the door or window corner, so that after installation on the door or window corner, the inner main reinforcement bar 11 can fit snugly against the door or window corner, achieving a stable reinforcement effect. Alternatively, the building corner can also be at the junction of a beam / column and a wall. The corner of the corner structure of the main reinforcement bar 11 can correspond to the angle between the beam / column and the wall, so that after installation on the door or window corner, the outer main reinforcement bar 11 can fit snugly against the door or window corner, thus achieving a stable reinforcement effect.

[0029] In this specific embodiment, both the first surrounding member 12 and the second surrounding member 13 are spiral stirrups with a spiral structure. The first surrounding member 12 is sleeved on the two extensions 112 of the main rib 11, surrounding and restricting the movement of the main rib 11. By surrounding and restricting the extensions 112 of each main rib 11 with the first surrounding member 12, it is possible to ensure that the distance between the main ribs 11 remains fixed, preventing any main rib 11 from shifting or deforming during assembly or transportation. The second surrounding member 13 is disposed in the corner structure and is in close contact with the bent portion 111 of each main rib 11. In other words, the second surrounding member 13 directly and tightly abuts against the bent portion 111 of the main rib 11, further enhancing the overall structural stability of the corner reinforcement kit 1. In practice, the first surrounding member 12 is mainly used to surround and fit around the extensions 112 of the four main reinforcing bars 11 to limit and ensure that the main reinforcing bars 11 maintain a fixed distance from each other; while the second surrounding member 13 is set in the corner structure, that is, inside the bends 111 of the four main reinforcing bars 11, and closely abuts against each bend 111. The first surrounding member 12 and the second surrounding member 13 can be fixedly connected to the main reinforcing bars 11 by at least one of welding, mechanical snap-fitting or binding to improve the support rigidity and stability under seismic shear force, not only making the corner structure more stable, but also providing immediate support at the corner of the main reinforcing bar (i.e., the corner structure) when the first surrounding member 12 is under force. Therefore, the corner reinforcement kit 1 can share the load and shear force from the doors, windows, walls and / or floors through the first surrounding member 12 and the second surrounding member 13, effectively avoiding corner deformation and material fatigue.

[0030] It is worth noting that, in this specific embodiment, the first surrounding member is a spiral stirrup with a spiral structure, but it is not limited to this. In practice, the first surrounding member can be a single-loop annular stirrup fitted onto the extension of the main reinforcement, or it can be a plurality of annular stirrups arranged at equal or non-equal intervals fitted onto the extension of the main reinforcement. In addition, the first surrounding member can be a surrounding stirrup formed by the cross-sectional shape corresponding to the extension of the main reinforcement.

[0031] In practical applications, the corner reinforcement kit 1 of this invention can be adapted to different construction environments through various installation modes. For example, the corner reinforcement kit 1 can be pre-assembled, with the main reinforcement 11, the first surrounding member 12, and the second surrounding member 13 assembled in the factory to ensure overall stability. Then, the assembled corner reinforcement kit 1 is transported to the construction site for direct use. Alternatively, on-site installation can be used, where the main reinforcement 11, the first surrounding member 12, and the second surrounding member 13 are transported to the construction site separately, and then assembled and fixed. Since the main reinforcement 11, the first surrounding member 12, and the second surrounding member 13 can be made of high-strength steel with heat treatment or electroplating for corrosion resistance, the corner reinforcement kit 1 of this invention is suitable for harsh environments such as high humidity and high salinity without the need for a protective layer, thus avoiding rust problems and improving building lifespan and reinforcement durability.

[0032] The corner reinforcement kit 1 of this invention fixes the relative positions of the main reinforcing bars 11 through the first surrounding member 12, ensuring the structural stability of the corner reinforcement kit 1. Furthermore, the second surrounding member 13 supports the bend 111, further effectively dispersing local stress at the building corner, thereby reducing the risk of damage caused by stress concentration. Moreover, when the building is affected by an earthquake, the corner reinforcement kit 1 of this invention can effectively absorb and disperse the seismic energy, thereby effectively reducing deformation or damage to the building corner. Therefore, the corner reinforcement kit 1 of this invention has good earthquake resistance and can effectively improve the structural strength of the building corner, thereby improving its durability and ensuring the safety and stability of the building during long-term use.

[0033] Furthermore, the present invention provides other embodiments. Please refer to Figure 2, which is a schematic diagram illustrating a corner reinforcement kit 2 according to another specific embodiment of the present invention. As shown in Figure 2, the main reinforcement 21 of the corner reinforcement kit 2 in this specific embodiment is a frame structure formed by two sets of closed L-shaped frames made of steel bars. In addition, the closed frame structure of the corner reinforcement kit 2 in this specific embodiment is not easily deformed or loosened during transportation, and can further ensure rapid installation and accuracy on the actual construction site. Other devices and their corresponding functions in this specific embodiment are substantially the same as those in the aforementioned specific embodiments, and therefore will not be described again here.

[0034] Furthermore, the present invention provides other embodiments. Please refer to Figure 3, which is a schematic diagram illustrating a corner reinforcement kit 3 according to another specific embodiment of the present invention. As shown in Figure 3, the corner reinforcement kit 3 of this specific embodiment further includes two U-shaped corner brackets 34. In practice, the U-shaped corner brackets 34 can be made by bending steel bars into a U-shape, and then placing the two U-shaped corner brackets 34 in the second surrounding member 33 to provide a support effect. In addition, in this specific embodiment, the arc portion of the U-shaped corner bracket 34 can also be fixedly connected to the main reinforcement by at least one of welding, mechanical snap-fitting, or binding, and the second surrounding member 33 can also be fixedly connected to the U-shaped corner bracket 34 by at least one of welding, mechanical snap-fitting, or binding. Furthermore, the number of U-shaped corner brackets in this embodiment is two, but the number is not limited to this, and one or more U-shaped corner brackets can be placed according to the reinforcement requirements. The other devices and their corresponding functions in this specific embodiment are substantially the same as the devices corresponding to the foregoing specific embodiments, and therefore will not be described again here.

[0035] Furthermore, the present invention provides other embodiments. Please refer to FIG4, which is a schematic diagram illustrating a corner reinforcement kit 4 according to another specific embodiment of the present invention. As shown in FIG4, the corner reinforcement kit 4 of this specific embodiment includes a U-shaped corner bracket 44 and a second surrounding member 43. The difference between the U-shaped corner bracket 44 and the second surrounding member 43 of this specific embodiment and other embodiments is that the two ends of the U-shaped corner bracket 44 of this specific embodiment gradually open away from the U-shaped arc portion, and the outer diameter of the second surrounding member 43 gradually increases from one end of the second surrounding member to the other end in order to match the shape of the U-shaped corner bracket 44. In other words, the second surrounding member 43 is a variable diameter spiral structure, which not only ensures that it can be installed in the bend portion 111 of the main rib 11, but also provides a wider range of support. For example, in practical applications, when cement grout is poured into the corner of a building, the second surrounding member 43 can fill the area that the first surrounding member 12 in other embodiments could not fully cover, further making the overall support of the corner reinforcement kit 4 more uniform, thereby improving the structural strength in building reinforcement. The other devices in this specific embodiment and their corresponding functions are roughly the same as the devices corresponding to the aforementioned specific embodiments, so they will not be described again here.

[0036] It is worth noting that the U-shaped corner bracket of the corner reinforcement kit of the present invention is not limited to the shapes shown in Figures 3 and 4. In another embodiment, the U-shaped corner bracket may also be elliptical in shape. Therefore, the outer diameter of the second surrounding member gradually increases from one end of the second surrounding member and then gradually decreases. Furthermore, the shape of the second surrounding member is not limited to the spiral stirrups shown in Figures 3 and 4. In practice, the second surrounding member may be a single-loop annular stirrup fitted onto the U-shaped corner bracket, or it may be a plurality of annular stirrups arranged at equal or non-equal intervals fitted onto the U-shaped corner bracket.

[0037] The present invention further provides a method for manufacturing a corner reinforcement kit. Please refer to Figure 5, which is a flowchart illustrating the steps of manufacturing a corner reinforcement kit according to another specific embodiment of the present invention. The method for manufacturing a corner reinforcement kit in this specific embodiment can produce the corner reinforcement kit 1 described above. As shown in Figure 5, the method for manufacturing a corner reinforcement kit in this specific embodiment includes the following steps: Step S1: Prepare a plurality of main ribs, a plurality of first surrounding members, and a second surrounding member, wherein each main rib includes a bent portion and two extensions connecting the bent portion; Step S2: Arrange the bent portions of the main ribs in parallel to form a corner structure; Step S3: Fit each first surrounding member onto the extension of the main rib to fix the main rib in a relative position; and Step S4: Set the second surrounding member in the corner structure, so that the second surrounding member is surrounded by the bent portion of the main rib and tightly abuts against the bent portion.

[0038] The present invention further provides a method for manufacturing a corner reinforcement kit. Please refer to Figure 6, which is a flowchart illustrating the steps of manufacturing a corner reinforcement kit according to another specific embodiment of the present invention. As shown in Figure 6, the method for manufacturing a corner reinforcement kit according to this specific embodiment includes the following steps: Step S1: Prepare a plurality of main ribs, a plurality of first surrounding members, and a second surrounding member, wherein each main rib includes a bent portion and two extensions connecting the bent portion; Step S11: Prepare a U-shaped corner frame; and fit the second surrounding member onto the U-shaped corner frame; Step S2: Arrange the bent portions of the main ribs in parallel to form a corner structure; Step S3: Fit each first surrounding member onto the extension of the main rib to fix the main rib in a relative position; and Step S41: Set the U-shaped corner frame and the second surrounding member in the corner structure, so that the second surrounding member is surrounded by the bent portion of the main rib and tightly abuts against the bent portion. The components described in the manufacturing method of the corner reinforcement kit in this specific embodiment have already revealed their structural features or application methods in the aforementioned specific embodiments (i.e., corner reinforcement kits 3 and 4), so they will not be repeated here.

[0039] In summary, this invention provides a corner reinforcement kit that uses a first surrounding member to fix the relative positions of the main reinforcing bars, ensuring the structural stability of the corner reinforcement kit. Furthermore, the second surrounding member provides support at the bend, further effectively dispersing local stress at the building corner, thereby reducing the risk of damage caused by stress concentration. In practice, the corner reinforcement kit of this invention is easy to assemble and transport, making it more convenient for on-site assembly or direct use. Furthermore, since the corner reinforcement kit of this invention uses the first surrounding member to fit over both ends of the main reinforcing bars to fix the distance between each main reinforcing bar, in practical applications, the size of the corner reinforcement kit can be adjusted according to the actual thickness of the building corner in each building to meet different size requirements. Therefore, the corner reinforcement kit of this invention can effectively solve the problems caused by inconvenient installation, insufficient size adaptability, or poor structural strength in the prior art, thereby improving the reinforcement effect of door and window corners and ensuring the seismic resistance and long-term stability of buildings.
