With the acceleration of urbanization and the improvement of people's requirements for the urban environment, higher standards have been put forward for the linearity and appearance quality of ditches. Traditional ditch formwork construction technology mostly uses wooden formwork with square wood as back ribs, and then uses steel pipes for reinforcement. Although this method meets the construction needs to a certain extent, it has problems such as cumbersome operation, low construction efficiency, and serious material waste. Especially in large-scale ditch construction, these problems are particularly prominent, which not only affects the construction progress, but also increases the construction cost.

[0003] Therefore, there is an urgent need for a concrete ditch formwork fixing bracket with a simple structure, easy operation and reusability to improve construction efficiency, reduce labor input, reduce construction costs, and ensure the construction quality of the ditch. The utility model comes into being in this context, aiming to provide a more efficient and economical solution for urban ditch construction through technological innovation. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a simple and reusable concrete ditch template fixing bracket, such as Figure 1-Figure 3As shown, the bracket body includes a horizontal fixed tie rod 1, a vertical fixed rod 2, a horizontal inner support rod 3, and an angle support rod 4. The bracket body is fixed horizontally by a tension fixing screw rod 5. The two ends of the tension fixing screw rod 5 pass through the concrete area. The tension fixing screw rod 5 is sleeved with a PVC sleeve 6 near the concrete area. The two ends of the PVC sleeve 6 are against the inner side of the steel formwork in the concrete area. The bracket body is the core part of the bracket, which is responsible for bearing and dispersing various stresses and loads during the construction process. The bracket body is composed of a horizontal fixed tie rod 1, a vertical fixed rod 2, a horizontal inner support rod 3 and an angle support rod 4. These components work together to form a stable spatial structure. The main function of these tie rods is to stabilize the bracket laterally to prevent it from being displaced or deformed in the horizontal direction. They connect different parts of the bracket to ensure that the entire bracket can maintain overall stability when subjected to external forces. The vertical fixed rod is the vertical support part of the bracket, which is responsible for bearing the vertical pressure from the construction load above. These rods are usually connected with transverse tie rods and transverse inner support rods to form a solid three-dimensional support system. The transverse inner support rods are mainly used to increase the transverse rigidity and stability of the bracket. They are usually arranged inside the bracket, connected with the vertical fixed rods and transverse tie rods to form a reinforced support network. The angle support rods are the corner support parts of the bracket. They are usually located at the four corners of the bracket to increase the corner stability of the bracket and prevent it from twisting or deformation. The tensioning and fixing screw rods 5 are the key connecting parts of the bracket. They connect the various parts of the bracket tightly together by lateral tensioning. The two ends of these screw rods pass through the concrete area to ensure a firm connection between the bracket and the concrete structure. The PVC sleeve 6 is set on the tensioning and fixing screw rods 5 near the concrete area. The main function is to protect the screw rods from corrosion and damage from concrete. At the same time, the two ends of the PVC sleeve 6 are against the inner side of the steel formwork in the concrete area, which plays a role of isolation and buffering, and prevents the screw rods from directly contacting the steel formwork to cause wear or deformation.

[0024] In this embodiment, the number of the transverse fixed rods 1 is one, the number of the vertical fixed rods 2 is four, the number of the transverse inner support rods 3 is 2-3, and the number of the angle support rods 4 is four.

[0025] Specifically, the transverse fixing rod 1 is horizontally arranged, the top end of the vertical fixing rod 2 is welded to the lower surface of the transverse fixing rod 1, the vertical fixing rods 2 are arranged at equal intervals, and the vertical fixing rods 2 are located on the outer side of the concrete area.

[0026] Furthermore, the transverse inner support rod 3 is located between the two vertical fixed rods 2 in the middle, the transverse inner support rod 3 is arranged parallel to each other up and down, and both ends of the transverse inner support rod 3 are welded and fixed to the vertical fixed rods 2.

[0027] Furthermore, the angle brace 4 is obliquely arranged at the connection between the transverse fixing rod 1 and the vertical fixing rod 2 , and the top end of the angle brace 4 is welded and fixed to the transverse fixing rod 1 , and the bottom end of the angle brace 4 is welded and fixed to the vertical fixing rod 2 .

[0028] Furthermore, the tension fixing screw rod 5 transversely penetrates the concrete areas at both ends to perform tensioning and supporting on the concrete areas.

[0029] Furthermore, the tension fixing screw rod 5 includes a threaded steel bar segment 51 located inside the concrete area and a spiral screw rod segment 52 located outside the concrete area, a first adjusting nut 53 is installed on one end of the spiral screw rod segment 52, and a second adjusting nut 54 is installed on the other end of the spiral screw rod segment 52.

[0030] Furthermore, the first adjusting nut 53 and the second adjusting nut 54 are both located outside the steel formwork in the concrete area.

[0031] When the simple and reusable concrete ditch formwork fixing bracket of the utility model is used, first, the transverse fixing rod 1 is horizontally arranged as the main transverse load-bearing and stabilizing component of the bracket. Then, the top ends of the four vertical fixing rods 2 are welded to the lower surface of the transverse fixing rod 1 to form a vertical support system of the bracket. These vertical fixing rods 2 are arranged at equal distances and located on the outer side of the concrete area to ensure effective support for the concrete formwork.

[0032] In order to enhance the lateral rigidity and stability of the bracket, the lateral inner support rods 3 are arranged between the two vertical fixed rods 2 in the middle, which are arranged parallel to each other and welded to the vertical fixed rods 2. In this way, the lateral inner support rods 3, the vertical fixed rods 2 and the lateral fixed tie rods 1 together form a solid support network.

[0033] The angle braces 4 are arranged obliquely and are welded and fixed to the transverse fixing rods 1 and the vertical fixing rods 2. The function of these angle braces 4 is to increase the stability of the bracket and prevent the bracket from twisting or deforming when subjected to external forces.

[0034] The tension fixing screw rods 5 are the key connecting parts of the bracket. They run through the concrete areas at both ends horizontally, and the concrete areas are tensioned and supported by the first adjustment nut 53 and the second adjustment nut 54. The tension fixing screw rods 5 include a threaded steel bar section 51 located inside the concrete area and a spiral screw rod section 52 located outside the concrete area. By rotating the adjustment nut, the length of the tension fixing screw rods 5 can be adjusted, thereby adjusting the tightness and stability of the bracket.

[0035] In order to protect the tension fixing screw rod 5 from corrosion and damage by concrete, the PVC sleeve 6 is sleeved on the tension fixing screw rod 5 near the concrete area. The two ends of the PVC sleeve 6 are against the inner side of the steel formwork in the concrete area, playing the role of isolation and buffering, preventing the screw rod from directly contacting the steel formwork and causing wear or deformation;

[0036] When the ditch concrete reaches the demoulding strength, remove the adjusting nut on one side, directly pull out the tension fixing screw rod 5, and then pull out the bracket body, collect and stack them neatly for use in the next ditch section.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
