Detailed Embodiment
[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.
[0020] This embodiment includes a horizontal cross bar 1. A sliding sleeve 2 is sleeved on the right side of the horizontal cross bar 1. The sliding sleeve 2 can slide left and right along the horizontal cross bar 1. A threaded hole is provided on the upper surface of the sliding sleeve 2, and bolt A 3 passes through the threaded hole. The sliding sleeve 2 is fixed on the horizontal cross bar 1 by tightening bolt A 3 passing through the threaded hole. The sliding sleeve 2 is integrally connected downward to a rectangular vertical rod 4. A wedge-shaped rod 5 and an inclined rod 6 are respectively fixed downward on the left side of the horizontal cross bar 1, and the inclined rod 6 is located on the right side of the wedge-shaped rod 5. The bottom surfaces of the above-mentioned vertical rod 4, wedge-shaped rod 5 and inclined rod 6 are on the same horizontal plane, and the bottom surfaces of the vertical rod 4, wedge-shaped rod 5 and inclined rod 6 are all connected downward to steel drill rods 7, and the steel drill rods 7 are used to insert into the ground to fix the device.
[0021] The above-mentioned diagonal rod 6 fixes the backrest formwork 8 to the right. The backrest formwork 8 is a hollow parallelogram plate, and the inclination angles of the side surface of the backrest formwork 8 and the diagonal rod 6 are both the inclination angles of the trapezoidal backrest design. The backrest formwork 8 is used to form the inclined side surface of the trapezoidal backrest, that is, the backrest side surface close to the green belt. The backrest formwork 8 is 5-10 m long. Adjacent backrest formworks 8 are connected together by connecting short blocks 10. The size of the connecting short block 10 matches the internal hollow size of the backrest formwork 8. The connecting short block 10 is also a parallelogram. Adjacent backrest formworks 8 can be inserted into the connecting short block 10. The connecting short block 10 can not only connect the left and right adjacent backrest formworks 8 together, but also prevent the leakage of grout at the joint of adjacent backrest formworks 8.
[0022] In this embodiment, the fixed connection method between the backrest formwork 8 and the diagonal rod 6 is as follows: A number of columns of threaded holes are provided on the left side surface of the backrest formwork 8 along the length direction of the backrest formwork 8 from top to bottom. The threaded holes do not penetrate the backrest formwork 8, that is, there are no threaded holes on the right side surface of the backrest formwork 8. Corresponding threaded holes are also provided on the diagonal rod 6 from top to bottom. The diagonal rod 6 and the backrest formwork 8 are fixed together by bolts B9 passing through the threaded holes of the backrest formwork 8 and the threaded holes of the diagonal rod 6. After being fixed, the bottom surface of the backrest formwork 8 is slightly higher than the bottom surface of the diagonal rod 6 because when fixing, a small part of the bottom of the diagonal rod 6 needs to be hammered into the ground.
[0023] To further ensure that the backrest formwork 8 does not shift during concrete pouring, it is preferably provided with a trapezoidal plug 11 between the backrest formwork 8 and the curb 12. The height of the trapezoidal plug 11 is lower than the height of the backrest formwork 8. The trapezoidal plug 11 can be made of concrete blocks, etc. The vertical cross-sectional shape of the trapezoidal plug 11 is the same as the shape of the backrest vertical cross-section, and it can be tightly plugged between the backrest formwork 8 and the curb 12. A trapezoidal plug 11 can be inserted every few meters and can be poured into the concrete together during concrete pouring.
[0024] In this embodiment, the horizontal cross bar 1, the vertical bar 4, the diagonal rod 6, and the backrest formwork 8 are all made of aluminum alloy materials.
[0025] During construction, first, a number of horizontal crossbars 1 are successively placed above the upper surface of the already constructed curb 12. The distance between the horizontal crossbars 1 is equal to the distance between each column of threaded holes on the backrest formwork 8, that is, the inclined rods 6 are made to correspond to the columns of threaded holes on the backrest formwork 8 for fixing the backrest formwork 8 to the inclined rods 6 later. Move the horizontal crossbar 1 left and right to adjust the position of the inclined rod 6 so that the distance between the right side surface of the inclined rod 6 and the left side surface of the curb 12 is exactly the sum of the designed backrest thickness and the thickness of the backrest formwork 8. After adjustment, slide the sliding sleeve 2 to adjust the position of the vertical rod 4 so that the left side surface of the vertical rod 4 tightly abuts against the right side surface of the curb 12. Tighten the bolt A3 to fasten the sliding sleeve 2 to the horizontal crossbar 1. Tap the horizontal crossbar 1 downward so that the lower surface of the horizontal crossbar 1 is on the upper surface of the curb 12. At this time, the steel rod 7 is completely hammered into the ground, and at the same time, a small part of the bottom of the vertical rod 4, the inclined rod 6, and the wedge-shaped rod 5 is hammered into the ground. Then, fix the backrest formwork 8 to the inclined rod 6 by screwing in the bolt B9. The bottom surface of the backrest formwork 8 is closely attached to the ground and flush with the bottom surface of the curb 12. Adjacent backrest formworks 8 are connected together by connecting short blocks 10. After fixing the backrest formwork 8, insert trapezoidal plug blocks 11 between the backrest formwork 8 and the curb 12 every few meters, and then pour concrete between the backrest formwork 8 and the curb 12 to form a trapezoidal backrest.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of each embodiment of the present invention.
