[0002] Based on an ongoing construction project, the outer corner of the retaining wall capstone is designed with a 50*50 angle guide, and the inner bottom of the capstone is designed as a semicircular guide groove. Construction joints are set every 12 meters. During construction, a large amount of manual cutting of custom bamboo plywood is required, and it needs to be re-cut after each recycling. This method is currently widely used in the market for construction, which is time-consuming and labor-intensive. The use of the template device of the present invention can save a lot of manual cutting of templates, shorten the construction period, and improve construction progress and quality.

[0003] Traditional urban landscape gravity retaining wall capstone formwork is customized with bamboo plywood. For the outer corner position, 50*50 bamboo plywood strips need to be cut and installed. Cutting consumes a lot of manpower and material resources, and it is difficult to fix it during installation after cutting. When pouring concrete, it is easy to cause the 50*50 bamboo plywood guide angle to deform and move. The diversion trough is located below the capstone. During construction, bamboo plywood still needs to be cut and installed. The bamboo plywood is cut into a rectangle, which is inconsistent with the designed semicircular shape, affecting the water interception effect. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to solve the problems of the existing technology in the cap stone template, such as the time-consuming and labor-intensive cutting of bamboo plywood at the outer corner, the difficulty in fixing, and the easy deformation during pouring, and to improve the problem of the poor water interception effect caused by the traditional rectangular bamboo plywood in the diversion groove not conforming to the designed semicircular shape after cutting, the following technical solutions are proposed. Figure 1-3 ;

[0025] A convenient gravity retaining wall capstone formwork device comprises a formwork body 1. The formwork body 1 is located above the retaining wall body 8. Concrete is poured into the formwork body 1 to form the capstone.

[0026] The formwork body 1 is made of bamboo plywood, which has the characteristics of being light and strong. It can also be dismantled and recycled after the concrete is poured, which can significantly save costs.

[0027] Customized 45° steel sections 2 are symmetrically provided at the inner top corners of the formwork body 1. By combining the customized 45° steel sections 2 with bamboo plywood, the stability of the structure is enhanced, and the construction quality and efficiency of the upper external corners are effectively improved. At the same time, due to the high strength and durability of the customized 45° steel sections 2, rework caused by material deformation is reduced, further improving construction efficiency.

[0028] A customized special-shaped steel 6 is installed at the bottom positive corner position of the template body 1, and a special retention groove mold 4 is installed at the inner bottom position of the template body 1 to form a semicircular diversion groove for drainage and prevention of soil erosion; the use of the special retention groove mold 4 makes the semicircular design of the diversion groove more precise, avoiding the problem of non-conformity of the design after cutting of traditional rectangular bamboo plywood, thereby improving the water interception effect.

[0029] Customized special-shaped steel 6 is welded to the special interception groove mold 4 to ensure the accurate position and diversion quality of the diversion groove.

[0030] Since the lower part of the guide trough is in a suspended state, a 50*50 angle steel 5 is provided at the bottom of the formwork body 1 for support. One end of the 50*50 angle steel 5 is welded to the customized special-shaped steel 6, and the other end is connected to the cast retaining wall 8 through a steel pad 7; the steel pad 7 can be used to adjust the horizontality of the formwork body 1 or serve as a buffer layer between the formwork body 1 and the ground.

[0031] The above installation method forms a self-service support system, which can effectively support the weight of the bottom of the template body 1, and is fixed by pulling through the wall pull rod 13. There is no need to set up a special clamp under the guide groove to complete the fixation of the entire template body 1 device. It not only simplifies the installation process, but also improves the stability of the template body 1.

[0032] The customized 45° steel section 2 is provided with connecting steel plates at both ends, which fit the inner side of the formwork body 1. The connecting steel plates are connected to the formwork body 1 through fixing nuts 12. The customized 45° steel section 2 provides structural strength. The customized angle of 45° can be used for specific angle support or connection to ensure the stability of the formwork body 1.

[0033] A fixing rod 9 is provided at the top of the formwork body 1. One side of the fixing rod 9 is connected to the customized 45° steel 2 and the bamboo plywood through an openable hinge 10, and the connection adopts a form similar to a gate knife; the other side of the fixing rod 9 is connected to the customized 45° steel 2 on this side through a self-propelled fixing buckle 11.

[0034] The fixing rod 9 is composed of two steel plates. There are three openings on the fixing rod 9 with a spacing of 5 mm. The holes can be used to adjust the tightness of the template body 1.

[0035] A through-wall tie rod 13 is provided in the middle of the formwork body 1. The through-wall tie rod 13 passes through the formwork body 1 and is connected to the L-shaped steel formworks 3 on both sides. The L-shaped steel formworks 3 can provide additional support and strength. The through-wall tie rod 13 is used for pulling and fixing, which can provide tension on both sides of the formwork body 1, ensure the stability of the formwork body 1, and withstand the pressure of concrete during concrete pouring to prevent the formwork body 1 from deformation or movement.

[0036] During installation, the device can be separated into two sides, and the left half is installed first, and then the right half. The 50*50 angle steel 5 at the guide trough position of the right part is placed on the retaining wall 8 that has been cast, and then the through-wall pull rod 13 and the upper fixing rod 9 are fixed at the same time to make the overall structure stable. The suspended position of the lower guide trough is naturally transferred downward to the 50*50 angle steel 5 for support due to the deadweight of the formwork body 1 and the deadweight of the concrete to be cast, so that the device is in a stable state.

[0037] Working principle: Combine the customized 45° steel 2 and L-shaped steel formwork 3 with bamboo plywood to form the formwork body 1; install a special retention groove mold 4 at the bottom of the cap stone to ensure that the semicircular design of the diversion groove meets the design requirements; add 50*50 angle steel 5 at the bottom of the formwork body 1 as support, one end is welded to the customized special-shaped steel 6, and the other end is connected to the cast retaining wall 8 through the steel pad 7; then use the through-wall tie rod 13 to pull and fix, and use the openable hinge 10 to effectively connect the fixing rod 9 to the customized 45° steel 2, and then connect it to the bamboo plywood; after confirming that the formwork body 1 is stable and all components are correctly fixed, start pouring concrete. The pouring should be carried out evenly to avoid excessive lateral pressure on the formwork body 1; after the concrete solidifies and reaches the design strength, remove the formwork body 1.
