Description

Technical Field

[0001] This utility model relates to the technical field of building construction, specifically to a corner post fixing device. Background Technology

[0002] Corner columns are vertical load-bearing components located at the corners of buildings or structures in architectural engineering, typically connecting walls, frames, or other structural components in different directions. Their main function is to transfer vertical loads (such as the self-weight of the superstructure and live loads), while simultaneously enhancing the overall rigidity and lateral displacement resistance of the structure, especially improving structural stability when resisting horizontal forces (such as wind and seismic forces). In the construction of cast-in-place concrete corner columns, they need to be formed using formwork and other fixing devices. The quality of the formwork fixing directly determines the forming accuracy and structural safety of the corner column. The joints of corner column formwork are generally concentrated at the corners. Traditional fixing devices have weak constraint force in this area, making it prone to corner bulging, cracking, and grout leakage under the lateral pressure of concrete, affecting the appearance quality of the formed column. Utility Model Content

[0003] This utility model proposes a corner post fixing device, which uses positioning holes to cooperate with the first positioning post and the second positioning post for positioning. Under the action of the locking member, the corner post template and the edge block are tightened, so as to realize the fast and accurate installation of the fixing mechanism.

[0004] Therefore, the technical solution adopted is as follows:

[0005] A corner post fixing device includes four corner post templates forming a rectangular corner post space. An L-shaped plate forming the inner corner of the corner post is fixed inside the corner post space. An edge-sealing block is fixed at the joint between every two corner post templates. The outer side of each corner post template also has a fixing mechanism. The fixing mechanism includes several horizontally arrayed first positioning posts fixed to the outer wall of the corner post template. A first fixing plate is fixed to the outer wall of one set of corner post templates, and a second fixing plate is fixed to the outer wall of another set of corner post templates. Both the first and second fixing plates have several positioning holes that match the first positioning posts. The first and second fixing plates are positioned relative to the corner post template by inserting the first positioning posts into the positioning holes. Both ends of the first fixing plate are fixedly connected to both ends of the second fixing plate by a locking member.

[0006] A further technical solution is that the fixing mechanism has multiple sets arranged in a vertical array along the four corner column templates.

[0007] A further technical solution is that the cross-section of the edge-binding block is L-shaped.

[0008] A further technical solution is that a second positioning post is fixed on the outer wall of the edge-binding block. There are two second positioning posts, which are located on the two sides of the edge-binding block respectively. The second positioning post is adapted to the positioning hole and is at the same height as the first positioning post.

[0009] A further technical solution is that the locking component includes a locking bolt, a sleeve block, and a locking nut. The locking bolt is fixed to both ends of the second fixing plate, and the sleeve block is fixed to both ends of the first fixing plate. The sleeve block has through holes, and the locking bolt passes through the corresponding through holes and is locked by the locking nut.

[0010] The working principle and beneficial effects of this application are as follows:

[0011] 1. Positioning is achieved by using positioning holes to cooperate with the first and second positioning posts. Under the action of locking components, the corner column template and edge block are tightened, realizing the fast and accurate installation of the fixing mechanism without repeated adjustments, which significantly improves the formwork efficiency.

[0012] 2. The additional edge-sealing blocks cover the formwork joints, significantly enhancing the integrity and rigidity of the corners, preventing deformation or cracking of the corners under the lateral pressure of the concrete, and effectively sealing the joints to reduce grout leakage.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1-4 As shown, a corner post fixing device includes four corner post templates 1 that form a rectangular corner post space. An L-shaped plate 2 forming the inner corner of the corner post is fixed inside the corner post space. An edge-sealing block 3 is fixed at the joint between every two corner post templates 1. A fixing mechanism 4 is also provided on the outside of each corner post template 1. The fixing mechanism 4 includes several horizontally arranged first positioning posts 5 fixed to the outer wall of the corner post template 1. A first fixing plate 41 is fixed to the outer wall of one set of corner post templates 1, and a second fixing plate 42 is fixed to the outer wall of another set of corner post templates 1. Several positioning holes 43 matching the first positioning posts 5 are provided on both the first fixing plate 41 and the second fixing plate 42. The first fixing plate 41 and the second fixing plate 42 are positioned relative to the corner post template 1 by inserting the first positioning posts 5 into the positioning holes 43. Both ends of the first fixing plate 41 are fixedly connected to both ends of the second fixing plate 42 by a locking member 44.

[0021] In this embodiment, the corner column template 1 is the main body constituting the corner column forming surface. The four corner column templates 1 form a rectangular cavity of the required size. An L-shaped plate 2 is installed on the inner side to form the precise inner corner of the template. Concrete is poured into the L-shaped cavity formed on the outer side of the L-shaped plate 2 to form the corner column. Among them, by setting the edge block 3, which is installed at the intersection of the corners of the four corner column templates 1, the template splicing seam is covered, which significantly enhances the integrity and rigidity of the corner, prevents the corner from deforming or cracking under the lateral pressure of concrete, and effectively seals the joint to reduce grout leakage. In addition, by installing multiple fixing mechanisms 4 on the outer side of the four corner column templates 1, the template and the edge block 3 are responsible for clamping the template and resisting the lateral pressure of concrete.

[0022] Specifically, fixing plate 41 and fixing plate 42 are symmetrically distributed on the outside of the rectangle as clamping force-bearing components. They are positioned by cooperating with the first positioning post 5 and the second positioning post 6 through the positioning hole 43. Under the action of the locking member 44, the corner column template 1 and the edge block 3 are tightened to ensure that the fixing mechanism is installed in a precise position and the force is evenly distributed.

[0023] like Figures 1-2 As shown, the fixing mechanism 4 has multiple sets arranged vertically along the four corner column templates 1 to ensure uniform and stable force application and sufficient strength. The edge-sealing block 3 has an L-shaped cross-section, which fits the outer corner of the template, increases the stress area at the corner, prevents the corner from deforming or cracking under the lateral pressure of the concrete, and effectively seals the joint to reduce grout leakage.

[0024] In addition, two second positioning posts 6 are fixed on the outer wall of the edge-binding block 3, located on the two sides of the edge-binding block 3 respectively. The second positioning posts 6 are adapted to the positioning holes 43 and are at the same height as the first positioning posts 5. The second positioning posts 6 are fixed on the outside of the edge-binding block 3, corresponding to the height of the first positioning posts 5, and are also inserted into the positioning holes 43, so that the fixing mechanism 4 connects the corner post template 1 and the edge-binding block 3 at the same time, enhancing the overall connection strength.

[0025] like Figures 3-4 As shown, the locking component 44 includes a locking bolt 441, a sleeve block 442, and a locking nut 443. The locking bolt 441 is fixed to both ends of the second fixing plate 42, and the sleeve block 442 is fixed to both ends of the first fixing plate 41. The sleeve block 442 has through holes, and the locking bolt 441 passes through the corresponding through holes and is locked by the locking nut 443. By fitting the sleeve block 442 at the end of the first fixing plate 41 onto the locking bolt 441 at the end of the second fixing plate 42, and then screwing the locking nut 443 into the locking bolt 441 and tightening it, the preload of the locking nut 443 brings the first fixing plate 41 and the second fixing plate 42 closer together, thereby applying clamping force to the corner column template 1 and the edge block 3 from four directions, firmly fixing them.

[0026] During installation, the four corner column templates 1 are first assembled into a rectangular shape, and the L-shaped plate 2 is installed on the inside. Then, the edge-binding block 3 is installed at the outer corner of the four corner column templates 1. The edge-binding block 3 has an L-shaped cross section, and its inner side is completely fitted with the outer corner of the two adjacent corner column templates 1, so that the edge-binding block 3 and the corner column template 1 form a corner structure. At this time, the second positioning post 6 on the outside of the edge-binding block 3 corresponds one-to-one with the first positioning post 5 on the outside of the template in terms of height, providing a positioning reference for the subsequent installation of the fixing mechanism 4.

[0027] Next, multiple fixing mechanisms 4 are installed at equal intervals in the vertical direction. The installation steps for each fixing mechanism 4 are as follows:

[0028] A pair of fixing plates 41 and a pair of fixing plates 42 are symmetrically distributed on the outside of the rectangular corner column template 1. The positioning holes 43 on the fixing plates are respectively fitted into the first positioning post 5 of the corner column template 1 and the second positioning post 6 of the edge-binding block. The cooperation between the positioning post 6 and the positioning hole 5 ensures that the fixing mechanism 4 does not shift in the horizontal direction. Then, the end sleeve 442 of fixing plate 41 is fitted onto the locking bolt 441 at the end of fixing plate 42, and then the locking nut 443 is screwed into the locking bolt 441. 41. Tighten the screws. Through the pre-tightening force of the locking nut 443, the fixing plate 1 and the fixing plate 2 42 are firmly fixed. After the fixing is completed, concrete is poured into the L-shaped cavity formed by the corner column template 1. The corner column template 1, the edge block 3 and the fixing mechanism 4 jointly resist the lateral pressure of the concrete to ensure the corner column is formed. After the concrete solidifies, loosen the locking nut 443, remove the locking bolt 441 and the sleeve block 442, remove the fixing mechanism 4, and then remove the edge block 3 and the corner column template 1 in sequence to complete the corner column pouring.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
