Description

Technical Field

[0001] The utility model relates to the field of building construction auxiliary facilities, in particular to a fixed combined formwork device for shear wall internal corner construction. Background Technique

[0002] In the construction industry, as an important part of the structural system, the construction quality of shear walls is directly related to the safety and aesthetics of the overall building. The internal corner of the shear wall is a key part of the shear wall structure, and the control of its construction quality is particularly important. However, in the existing construction process of shear wall internal corners, there are generally some problems that are difficult to overcome. These problems not only affect the construction efficiency but also significantly increase the workload of later repairs, thereby increasing the project cost.

[0003] First of all, in the traditional construction method of shear wall internal corner formwork, during the concrete pouring process, due to the large lateral load, the formwork is prone to deformation, resulting in quality problems such as formwork explosion, inclination, and protrusion at the internal corner part. These problems make the flatness of the internal corner part significantly different from that of the entire wall surface, seriously affecting the structural appearance quality. In addition, the problem that the two adjacent sides of the internal corner are not perpendicular also occurs from time to time, further exacerbating the decline in construction quality.

[0004] Secondly, due to the great construction difficulty of the shear wall internal corner part, most of the existing technical solutions are complex in structure, inconvenient to operate, and high in cost, and often require a large amount of manpower and material resources for later repairs. This not only increases the construction cost but also prolongs the construction period. The repair work not only requires precise technology and meticulous operation but also needs to consider the coordination with the overall structure. Therefore, it is often difficult to achieve an ideal effect and meet the actual construction requirements.

[0005] Therefore, how to provide a more efficient and reliable fixed combined formwork device for shear wall internal corner construction is an urgent technical problem to be solved in this field. Content of the Utility Model

[0006] In view of the work needs and existing problems in the above background technique, the present invention has carried out thinking and innovation. The purpose is to provide a fixed combined formwork device for shear wall internal corner construction. By optimizing the formwork structure, enhancing the stiffness and stability of the formwork, and simplifying the installation and disassembly process, etc., the construction quality of the shear wall internal corner can be effectively improved, the construction cost and the workload of later repairs can be reduced, and at the same time, the construction efficiency and safety can be improved.

[0007] To solve the above problems and achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A fixed combined formwork device for shear wall internal corner construction, which includes:

[0009] The formwork frame (1), which is the main structure of this device, is evenly and symmetrically distributed with 4 circular holes;

[0010] The top support plate (2), which is in an overall "L" shape, is connected to the top of the formwork frame (1);

[0011] There are 2 vertical support columns (3) in total. One end of each column is connected to the top support plate (2), and the other end is connected to the bottom of the formwork frame (1);

[0012] There are 4 horizontal reinforcement plates (4) in total, which correspond to the positions of the 4 circular holes of the formwork frame (1) one by one. The horizontal reinforcement plates (4) are fixedly connected to the vertical support columns (3) and form a "cross" structure.

[0013] As a preferred solution of the present utility model, the formwork frame (1) includes:

[0014] The first side elevation formwork (11), which is perpendicular to the second side elevation formwork (12) and is evenly distributed with two circular holes;

[0015] The second side elevation formwork (12), which is perpendicular to the first side elevation formwork (11) and is evenly distributed with two circular holes at the positions symmetrical to the first side elevation formwork (11);

[0016] The reinforcing rib (13), which is located at the connection between the first side elevation formwork (11) and the second side elevation formwork (12). One end of the reinforcing rib is connected to the top support plate (2), and the other end is connected to the bottom plate (14);

[0017] The bottom plate (14), which is perpendicular to the first side elevation formwork (11) and the second side elevation formwork (12).

[0018] As a preferred solution of the present utility model, this fixed-type combined formwork device further includes a tie rod (5), which passes through the circular hole of the formwork frame (1) and is detachably connected to the horizontal reinforcement plate (4) through a nut.

[0019] As a preferred solution of the present utility model, this fixed-type combined formwork device further includes an inclined support mechanism (6). There are 2 inclined support mechanisms (6) in total. One end of each mechanism is connected to the horizontal reinforcement plate (4) on the first side elevation formwork (11), and the other end is connected to the horizontal reinforcement plate (4) on the second side elevation formwork (12). The inclined support mechanism (6) is detachably connected to the formwork frame (1).

[0020] As a preferred embodiment of the present utility model, the inclined support mechanism (6) includes:

[0021] A connecting member (61), one end of the connecting member (61) is detachably connected to the first side elevation formwork (11) through bolts and nuts, and the other end is detachably connected to the inclined support plate (62) through bolts and nuts;

[0022] An inclined support plate (62), the inclined support plate (62) is disposed at an angle of 45° between the first side elevation formwork (11) and the second side elevation formwork (12).

[0023] The working principle of the present utility model is as follows: The device is composed of three specially designed formworks. Two of the formworks are used as the formworks against the wall, which are arranged perpendicular to each other, and the third formwork is perpendicular to these two formworks, forming the basic structure of the shear wall internal corner; the reinforcing ribs (13) further stabilize the entire structure. The formworks against the wall are provided with tie rod holes at fixed intervals, so as to tightly connect the formworks with the wall structure through the tie rods (5) and the matching nuts. At the same time, the top support plate (2) and the vertical support columns (3) are used to enhance the stiffness of the formworks, ensuring that the formworks do not deform during the concrete pouring process. Horizontal inclined supports are installed on the two perpendicular formworks and fixed to the formworks through bolts, effectively dispersing the lateral forces received by the formworks, enhancing the overall stability of the formwork structure, and preventing the formworks from deforming or displacing due to the lateral pressure generated during the concrete pouring.

[0024] The beneficial effects of the present utility model:

[0025] 1. The present utility model improves the construction quality: Through modular and standardized design, the construction accuracy and stability of the shear wall internal corner part are ensured. The tight connection and effective reinforcement between the formworks effectively prevent the formworks from deforming and displacing during the concrete pouring process, thus avoiding problems such as formwork explosion, inclination, and protrusion at the internal corner part, significantly improving the flatness and perpendicularity of the internal corner part, and ensuring the aesthetic appearance and overall quality of the structure.

[0026] 2. The present utility model improves the construction efficiency: The modular design makes the formworks easy to assemble and disassemble, greatly shortening the construction period. At the same time, the standardized formworks and fittings make the construction process more standardized and streamlined, reducing errors and rework in the construction, and further improving the construction efficiency.

[0027] 3. The present utility model reduces the construction cost: Since the formwork materials are strong, durable, easy to clean and maintain, they can be repeatedly used in different shear wall internal corner constructions, thus reducing the consumption and waste of formworks and lowering the construction cost. At the same time, the high-quality construction effect reduces the workload of later repairs, further saving repair materials and labor costs.

[0028] 4. The present utility model improves construction safety: The inclined support design of the present utility model effectively enhances the overall stability of the formwork structure, preventing safety accidents such as the collapse or overturning of the formwork during construction. At the same time, the standardized construction process and operation specifications also reduce the safety risks during construction, ensuring the safety of construction personnel.
