Description

Technical Field

[0001] This utility model belongs to the field of building construction formwork reinforcement technology, and in particular relates to an adjustable reinforcement component. Background Technology

[0002] In the formwork reinforcement construction of cast-in-place concrete square columns, square and round buckles are often used as external reinforcement components. However, when there are local protrusions in the column or deviations in the position of reserved openings, irregular gaps will appear between the square and round buckles and the vertical back ribs on the back of the formwork. This will prevent the reinforcement components from fitting tightly, affecting the overall rigidity and stability of the formwork. The traditional approach is to fill the gaps with wooden blocks or steel bar ends for reinforcement. However, this method has problems such as incomplete filling, uneven stress, inconvenience in adjustment, and easy loosening. It is difficult to ensure the stability of the formwork during the concrete pouring process, which can easily lead to formwork displacement, grout leakage, or even bulging, affecting the forming quality of the column.

[0003] Chinese patent application CN219158181U discloses a U-shaped rebar threaded connector, comprising an inner sleeve with a through stepped hole, wherein a second straight thread and a third straight thread are respectively provided in the stepped hole, and a first straight thread is provided on the outer wall of the inner sleeve; a push rod including a coaxial screw section, a push section and a guide section, wherein a fourth straight thread is provided on the screw section; an outer U-sleeve with a coaxial inner hole and a necking platform, wherein a fifth straight thread is provided on the inner hole, and an inner end face of the necking platform is provided between the inner hole and the necking platform; an inner retaining sleeve with a through stepped inner hole, wherein a sixth straight thread and a small diameter hole are respectively provided in the stepped inner hole, and a cylindrical section and an annular boss are respectively provided on the outer wall of the inner retaining sleeve. An inner end face of the annular boss is provided between the cylindrical section and the annular boss; the inner sleeve is connected to the first reinforcing bar through the second straight thread, the third straight thread and the fourth straight thread cooperate to connect the inner sleeve to the screw section of the push rod, the guide section is inserted into the small diameter hole to connect the push rod to the inner retaining sleeve, the inner retaining sleeve is connected to the second reinforcing bar through the sixth straight thread, the first straight thread and the fifth straight thread cooperate to connect the inner sleeve to the inner retaining sleeve through the outer U-sleeve, the inner end face of the necked shoulder abuts against the inner end face of the annular boss, and at the same time, the end face of the top section of the push rod abuts against the outer end face of the inner retaining sleeve.

[0004] Although it solves the problem of misalignment of the threaded trajectory lines when connecting steel reinforcement components, and can achieve axis alignment between the inner retaining sleeve and the inner connecting sleeve, effectively improving the efficiency and quality of axis adjustment during steel reinforcement connection, reducing the adverse effects of axial eccentricity on threaded mating installation, and improving installation efficiency, it is suitable for modular and component-based connections of steel reinforcement in precast concrete structures. However, its complex structure, including multiple components such as the inner connecting sleeve, top rod, outer U-sleeve, and inner retaining sleeve, makes it difficult to process and manufacture, resulting in higher production costs. Furthermore, it requires precise matching of multiple threaded connection parts during installation, demanding a high level of operational proficiency from construction personnel, and the assembly steps are relatively cumbersome. It also has poor flexibility in confined construction environments.

[0005] Therefore, there is an urgent need to provide a new adjustable reinforcement mechanism to solve the above problems. Utility Model Content

The supporting steel bar is made of solid steel bar material, and it is connected to the U-shaped steel bar by full welding. This connection method aims to ensure that the two form a strong and continuous whole, thereby effectively transferring the load borne by the supporting steel bar to the U-shaped steel bar and the entire structural system.

[0013] The present invention is further configured such that the two straight threaded sleeves are of the same specification, and the inner wall of the straight threaded sleeve is provided with an internal thread that mates with the external thread.

[0017] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1 to 5 This embodiment provides an adjustable reinforcement component, including two support frame mechanisms 1. Each support frame mechanism 1 includes a U-shaped steel bar 2. A support steel bar 3 is fixedly connected to one side of the U-shaped steel bar 2 by welding. An adjustable mechanism 4 is provided on the surface of the support steel bar 3. The adjustable mechanism 4 includes two straight threaded sleeves 41. The two straight threaded sleeves 41 are fixedly connected by welding. One end of the support steel bar 3 is provided with an external thread 42. The threaded ends of the two support steel bars 3 are screwed into the inner cavity of the straight threaded sleeves 41 respectively.

[0019] Specifically: The supporting frame mechanism 1 is mainly composed of U-shaped steel bars 2, which are used to provide the main supporting structure; one side of the U-shaped steel bars 2 is fixedly connected to the supporting steel bars 3 by welding. The main function of the supporting steel bars 3 is to enhance the stability and load-bearing capacity of the overall structure; the surface of the supporting steel bars 3 is provided with an adjustable mechanism 4, which includes two straight threaded sleeves 41. The two straight threaded sleeves 41 are fixedly connected by welding to achieve mutual fixation. One end of the supporting steel bars 3 is provided with an external thread 42. By screwing the threaded ends of the two supporting steel bars 3 into the inner cavity of the straight threaded sleeves 41 respectively, the length of the supporting steel bars 3 can be adjusted and the overall mechanism can be flexibly assembled.

[0020] The U-shaped reinforcing bar 2 is formed by bending a straight reinforcing bar, and the two ends of the U-shaped reinforcing bar 2 are of equal length. The length of the external thread 42 on the surface of the supporting reinforcing bar 3 is greater than the length of the straight thread sleeve 41, and the diameter of the supporting reinforcing bar 3 is greater than the diameter of the U-shaped reinforcing bar 2. The U-shaped reinforcing bar 2 is used to snap onto the square and round buckle, and the opening width of the U-shaped reinforcing bar 2 matches the thickness of the square and round buckle. The welding between the straight thread sleeves 41 is double-sided welding, and the axes of the two straight thread sleeves 41 are parallel to each other. The supporting reinforcing bar 3 is made of solid reinforcing bar, and the welding between the supporting reinforcing bar 3 and the U-shaped reinforcing bar 2 is a full weld connection. The two straight thread sleeves 41 are of the same specification, and the inner wall of the straight thread sleeve 41 is provided with an internal thread that mates with the external thread 42.

[0021] Specifically: U-shaped steel bar 2 is a component formed by bending straight steel bars. Its two ends are of equal length, and the opening width is suitable for the thickness of the square / round buckle rod, used for securing the square / round buckle. Supporting steel bar 3 is made of solid steel bar with a diameter larger than U-shaped steel bar 2. Its surface is machined with external threads 42, the length of which exceeds the length of the straight threaded sleeve 41. The straight threaded sleeve 41 consists of two identical connecting parts, with internal threads on the inner wall matching the external threads 42 of the supporting steel bar 3. The axes of the two sleeves remain parallel, and they are connected as one unit by double-sided welding. Supporting steel bar 3 and U-shaped steel bar 2 are securely connected by full welding. The entire assembly achieves an adjustable function through threaded engagement, forming a structure for support and fixation.

[0022] The working principle of this utility model is as follows: During operation, the U-shaped steel bars 2 of the two supporting frame mechanisms 1 are first respectively snapped onto the outer components of the template to be reinforced, such as the square and round buckle, so that the openings of the U-shaped steel bars 2 are securely fitted to the square and round buckle rod body. Then, by rotating the adjustable mechanism 4, which is formed by welding two straight threaded sleeves 41 together, or by rotating the supporting steel bars 3 at both ends respectively, the supporting steel bars 3 with external threads 42 are screwed into or out of the internal threads of the straight threaded sleeves 41, thereby adjusting the overall length between the two supporting frame mechanisms 1. This adjustment process can precisely adapt to the actual gap size between the template and the back rib until the reinforcement tightly fills the gap and generates sufficient preload. Finally, through the welding connection between its supporting steel bars 3 and the U-shaped steel bars 2, and the reliable connection of the straight threaded sleeves 41, the reinforcement effectively transfers the load to the square and round buckle and the template system, achieving stable support and reinforcement of the template.
