[0028] The following will elaborate on the embodiments of the utility model in detail with reference to the drawings. However, the utility model can be implemented in many different ways defined and covered by the following.
[0029] Please refer to... together Figures 1 to 7, the slope support construction formwork of this embodiment includes a steel bar frame 1 arranged on the support pile 5 and an aluminum formwork 2 arranged on the steel bar frame 1. The steel bar frame 1 includes horizontal bars 11, and suspension ring flexible bolt assemblies 3 for connecting the aluminum formwork 2 are arranged at intervals on the horizontal bars 11. Two adjacent aluminum formworks 2 in the horizontal direction are connected by bolts 21. The suspension ring flexible bolt assembly 3 includes a suspension ring 31, a screw rod 32 and a nut 33. The suspension ring 31 is sleeved on the horizontal bar 11. The first end of the screw rod 32 is screwed with the suspension ring 31 and abuts against the horizontal bar 11 after passing through the suspension ring 31. The second end of the screw rod 32 passes through the aluminum formwork 2 and is screwed with the nut 33.
[0030] For the slope support construction formwork of this embodiment, screw holes for passing the screw rod 32 are opened on the aluminum formwork 2. The horizontal bar 11 is installed on the support pile 5. The position of the suspension ring 31 on the horizontal bar 11 is adjusted according to the position of the screw holes on the aluminum formwork 2. The screw rod 32 passes through the screw holes on the aluminum formwork 2 and is screwed with the suspension ring 31. The screw rod 32 is tightened so that the first end of the screw rod 32 abuts tightly against the horizontal bar 11. At this time, the position of the suspension ring 31 in the axial direction of the horizontal bar 11 is fixed, and the position of the screw rod 32 in the circumferential direction of the horizontal bar 11 is fixed. The nut 33 on the screw rod 32 is rotated to prevent the aluminum formwork 2 from slipping off the screw rod 32. The suspension ring flexible bolt assembly 3 can move freely along the horizontal bar 11 and be positioned after moving, and can be applicable to aluminum formworks 2 with different opening positions of screw holes, with a wide application range; two adjacent aluminum formworks 2 are connected by bolts 21, so that all the aluminum formworks 2 form an integral body. The single aluminum formwork 2 is light in weight and high in strength. On the one hand, it can prevent the screw from breaking and the formwork from deforming. On the other hand, it can reduce the labor intensity of formwork disassembly and installation, reduce labor costs, and improve construction efficiency; all the aluminum formworks 2 form an integral force and are connected to the support pile 5 through the steel bar frame 1, which can ensure the reliability of the reinforcement of the aluminum formwork 2 and prevent local formwork displacement, thereby reducing the apparent quality defects such as joint misalignment, formwork displacement, and honeycombing and pitting. Optionally, as Figure 1 shown, the steel bar frame 1 further includes a steel bar mesh 12. The steel bar mesh 12 and the horizontal bar 11 are fixed by spot welding. On the one hand, it can prevent the horizontal bar 11 from deforming and provide good support for the suspension ring flexible bolt assembly 3, thereby preventing local formwork displacement of the aluminum formwork 2. On the other hand, it can improve the strength of the concrete panel and extend the service life of the concrete panel. Optionally, the nut 33 is a hand-tightening wing nut, which does not require additional tools and is convenient for disassembly and assembly.
[0031] As Figure 6 and Figure 7As shown in the figure, in this embodiment, a capping beam 51 is arranged at the top of the retaining pile 5, and a movable formwork 4 for guiding concrete is arranged at the top end of the aluminum formwork 2. The movable formwork 4 includes a bottom plate 41 for connecting the top surface of the aluminum formwork 2 and a guiding plate 42 obliquely arranged on the bottom plate 41. A reserved casting opening is formed between the guiding plate 42 and the capping beam 51, which facilitates the rapid casting of concrete, can reduce the operation difficulty, and improve the casting efficiency.
[0032] As Figure 6 shown in the figure, in this embodiment, the guiding plate 42 is hinged to the bottom plate 41, and a diagonal brace 43 is hinged on the bottom plate 41. A plurality of card slots adapted to the diagonal brace 43 are arranged on the back surface of the guiding plate 42. The included angle between the guiding plate 42 and the bottom plate 41 is adjusted by inserting the diagonal brace 43 into different card slots; its structure is simple, and the guiding plate 42 can be adjusted in angle through the diagonal brace 43. When pouring concrete, the guiding plate 42 is placed horizontally, which can increase the operation space for construction workers, facilitate the construction workers to vibrate the concrete densely, and can ensure that the concrete at the joint is poured full.
[0033] As Figure 1 、 Figure 2 and Figure 6 shown in the figure, in this embodiment, a reinforcement structure is arranged on the aluminum formwork 2. The reinforcement structure includes bolt holes 22 arranged on the aluminum formwork 2 and bolts 23 adapted to the bolt holes 22. The bolt holes 22 on two adjacent aluminum formworks 2 are connected by bolts 23. By inserting the bolts 23 into the corresponding bolt holes 22 on two adjacent aluminum formworks 2, the connection strength between two adjacent aluminum formworks 2 can be further increased, so that the adjacent aluminum formworks 2 are integrally stressed and local formwork displacement will not occur, thus ensuring the appearance quality of the concrete panel. Optionally, the bolt holes 22 are square holes and the bolts 23 are cuboids, which can prevent the bolts 23 from rotating, increase the contact area between the inner wall surface of the bolt holes 22 and the outer wall surface of the bolts 23, and reduce the risk of the bolts 23 slipping off.
[0034] As Figure 6 shown in the figure, in this embodiment, the reinforcement structure further includes a wedge block 24 for inserting into the gap between the bolt hole 22 and the bolt 23. The wedge block 24 is inserted into the gap between the bolt hole 22 and the bolt 23, which can press the bolt 23 and limit the bolt 23 to prevent the bolt 23 from slipping off.

One end of the second connecting bar 542 is embedded in the support pile 5 and connected to the steel bars inside the support pile 5, and the other end is connected to the first connecting bar 541. The first connecting bar 541 and the horizontal bar 11 are on the same straight line, which is convenient for welding the first connecting bar 541 and the horizontal bar 11. The aluminum formwork 2 is fixed by the cooperation of the positioning bars 53 and the nuts 33. The hanging ring loose bolt assembly 3 is fixed on the horizontal bar 11. The horizontal bar 11 is integrally formed by full welding with the anchor bars 54. Finally, the support pile provides the anchoring force. Its structure is simple, the support and positioning effect is good, and the aluminum formwork 2 can be prevented from shifting. Optionally, the included angle between the first connecting bar 541 and the second connecting bar 542 is 135°.
[0036] As Figure 1 shown in the figure, in this embodiment, the slope support construction formwork further includes positioning bars 53. The first end of the positioning bar 53 abuts against the aluminum formwork 2, and the second end is connected to the support pile 5. The second end of the positioning bar 53 is embedded in the support pile 5. The length of the first end of the positioning bar 53 protruding from the support pile 5 is reserved according to the thickness of the concrete panel. The first end of the positioning bar 53 abuts tightly against the front of the aluminum formwork 2. Rotate the nut 33 on the screw rod 32 so that the nut 33 abuts tightly against the back of the aluminum formwork 2, thereby positioning the aluminum formwork 2 in the axial direction of the nut 33 and ensuring that the thickness of the concrete panel meets the requirements. Optionally, the second end of the positioning bar 53 is welded to the anchor bar 54.
[0037] In this embodiment, a gasket is sleeved on the screw rod 32. The gasket is arranged between the aluminum formwork 2 and the nut 33. The outer diameter of the gasket is larger than the aperture of the screw hole, which can prevent the concrete from flowing out from the screw hole.
[0038] As Figure 7 shown in the figure, in this embodiment, a connecting formwork 6 is connected to the bottom end of the aluminum formwork 2. The aluminum formwork 2 and the waist beam 52 are connected by using the connecting formwork 6. On the one hand, it can play a role in strengthening the connecting formwork 6; on the other hand, it can prevent the concrete from leaking out.
[0039] In this embodiment, drain pipes are arranged on the steel bar frame 1. The drain pipes are made of PVC pipes. Both ends of the PVC pipes are wrapped with geotextiles for isolation. One section of the PVC pipe is buried in a pre-set filter layer, and the other end abuts tightly against the aluminum formwork 2. The pipe body of the PVC pipe is tied and fixed to the steel bar frame 1 by steel wires. The whole PVC pipe is in a downward inclined posture for subsequent water flow collection and outflow. Optionally, the drain pipes are fixed on the steel bar mesh 12.
