Abstract
Description
Technical Field
[0001] This utility model relates to the field of wooden formwork reinforcement technology in building engineering, and in particular to a formwork joint reinforcement component. Background Technology
[0002] In building construction, formwork systems are used to support concrete structures, ensuring they maintain their correct shape and dimensions during pouring and curing. Formwork is typically constructed from spliced wooden or steel templates, and the stability of the joints directly affects the quality of the concrete structure. With continuous innovation in construction technology and materials, the concrete used in building construction, such as fine aggregate concrete and self-compacting concrete, has high scalability and fluidity. If only tie rods and joists are used at the formwork joints and external corners without more refined joint reinforcement measures, grout leakage is highly likely during the pouring of beams, slabs, walls, and columns. This will have a significant negative impact on on-site construction and subsequent cleanup, and may even lead to formwork deformation, affecting the concrete forming effect and structural strength. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies by providing a template joint reinforcement component that is simple in structure, easy to operate, low in cost, and reusable.
[0004] To achieve the above objectives, this utility model first proposes a template joint reinforcement component, including an L-shaped support rod, a second support, and a locking device. One end of the L-shaped support rod is provided with a thread to form a threaded section, and the other end forms a first support with an angle of no more than 90 degrees with the threaded section. One end of the second support is slidably fitted onto the threaded section of the L-shaped support rod as a sliding part, and the other end extends out of the sliding part and is perpendicular to the sliding part to form a support part. A clamping area for fixing the wooden template is formed between the first support and the second support. The locking device is threadedly connected to the threaded section and is used to lock the second support.
[0005] In this embodiment, the locking device is a locking nut, which is threaded onto the threaded section and placed on the side of the second support away from the first support.
[0006] In this embodiment, a collar with an outer diameter larger than the outer diameter of the locking nut is provided on the side of the locking nut that contacts the second support.
[0007] In this embodiment, the L-shaped support rod is a hook bolt.
[0008] In this embodiment, the second support includes a sleeve and an angle steel, the angle steel is fixed on the sleeve, and the sleeve is slidably fitted onto the threaded section.
[0009] In this embodiment, the sleeve is a steel sleeve, and angle steel is welded onto the sleeve.
[0010] With the above structure, this utility model has the following advantages:
[0011] 1. This device can clamp the template joints by using only the L-shaped support rod and the second support. Then, the locking device brings the second support close to the first support to lock and reinforce the template. The overall structure of this device is simple, easy to operate, low in cost, and reusable.
[0012] 2. The L-shaped support rod of this device uses hook bolts, the second support is made of sleeve and angle steel, and the locking device uses lock nuts. These components are common and simple parts, which can be directly processed from the surplus parts on the construction site, saving costs. Construction personnel do not need complicated training or professional skills to quickly complete the installation of this device, which greatly improves the efficiency of construction.
[0013] 3. This device is highly durable and easy to disassemble. After completing one construction task, it can be easily dismantled and used for the next construction, achieving reusability.
[0014] In summary, the implementation of this utility model can effectively improve the stability of template joints and construction efficiency, reduce construction risks, and ensure the forming quality of concrete structures. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.

[0019] like Figure 1As shown, a template joint reinforcement component includes an L-shaped support rod 1, a second support 2, and a locking device 3. One end of the L-shaped support rod 1 is provided with a thread to form a threaded section 12, and the other end forms a first support 11 with an angle of no more than 90 degrees with the threaded section 12. One end of the second support 2 is slidably fitted onto the threaded section 12 of the L-shaped support rod 1 as a sliding part, and the other end extends out of the sliding part and is perpendicular to the sliding part to form a support part. A clamping area for fixing the wooden template is formed between the first support 11 and the second support 2. The locking device 3 is threadedly connected to the threaded section 12, and the second support 2 is placed between the locking device 3 and the first support 11. The locking device 3 is used to lock the second support 2.
[0020] In this embodiment, the locking device 3 is a locking nut, which is threaded onto the threaded section 12 and positioned on the side of the second support 2 away from the first support 11. A collar with an outer diameter larger than the outer diameter of the locking nut is provided on the side of the locking nut that contacts the second support 2. The L-shaped support rod 1 is a hook bolt. The second support 2 includes a sleeve 22 and an angle steel 21, with the angle steel 21 welded to the sleeve 22. The diameter of the steel sleeve 22 is slightly larger than the threaded section 12, allowing the sleeve 22 to move freely on the threaded section after being fitted onto it. Furthermore, the sleeve 22 is a steel sleeve 22.
[0021] In use, the second support 2 is attached to the joint of the wooden template on the same plane, and the first support 11 is placed on the secondary keel at the external corner joint of the wooden template on different planes. Then, the second support 2 is moved closer to the first support 11 by the locking device 3. The clamping force of the first support 11 and the second support 2 is used to tie the angle steel 21 at the secondary keel together with the hook bolt, so as to ensure that the template joint is tight.
[0022] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made under the concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
