Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a protective frame for square pile shotcrete. Background Technology

[0002] Retaining structures are an active, rapid, and economical method of soil and rock reinforcement. They aim to utilize the inherent stability of the excavation face to create a unified, lightweight retaining structure through artificial intervention, thereby ensuring the safety and stability of the excavation and use of the foundation pit. The retaining structure is typically a shotcrete and anchor support during the excavation of precast square pile sections. The general approach involves anchoring steel reinforcement nails and wire mesh between the square piles, and then directly applying shotcrete at the mesh locations to form the corresponding shotcrete and anchor support structure.

[0003] During conventional shotcreting, the distance between the shotcrete nozzle and the surface of the square pile is very close. The high-speed splashing concrete particles will inevitably contaminate the surface of the square pile. The concrete will inevitably cause contamination to the surface of the square pile. Subsequently, tools such as electric picks, hammers, chisels, and angle grinders are needed to clean the concrete from the surface of the square pile. This requires additional manpower and resources for treatment, resulting in high costs. At the same time, when cleaning the upper surface of the square pile, the upper part of the square pile is relatively high, so there is a risk of working at height when cleaning manually. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a protective frame for shotcrete and anchor installation on square piles, which solves the problem that high-speed splashing concrete particles can easily contaminate the surface of square piles during shotcrete and anchor support construction, resulting in high cleaning costs and high risks.

[0005] To achieve the above objectives, the basic solution of this utility model is as follows: a square pile shotcrete protection frame, comprising:

[0006] The frame, with a shotcrete zone enclosed within it;

[0007] Several baffles are installed on the frame and can be located outside the shotcrete zone of the frame.

[0008] The technical principle of this utility model is as follows: During shotcreting, the square pile shotcrete anchor protection frame is transferred to the shotcrete area, and the outline of the frame body is adapted to the outline of the shotcrete area. At this time, the baffle is attached to or relative to the surface of the square pile, and then shotcreting is performed on the shotcrete area. The sprayed concrete can accurately adhere to the shotcrete area, and the baffle can block the surface of the square pile, so as to achieve the ultimate goal of not needing to clean the surface of the square pile after shotcreting between piles. It can carry out shotcreting between piles more safely and economically, ensuring construction progress and saving costs.

[0009] Once the shotcrete is completed in one shotcrete area, the square pile shotcrete anchor protection frame can be moved to another shotcrete area and the shotcrete operation can be repeated, which significantly improves the efficiency of shotcrete treatment between piles.

[0010] Furthermore, the baffle includes:

[0011] The upper baffle is installed on the top side of the frame.

[0012] Several side panels are installed on the sides of the frame.

[0013] With the above settings, the upper baffle and the side baffle can accurately block the surface of the square piles on the upper and side sides of the frame, so that the blocking positions of the upper baffle and the side baffle are precisely matched with the surface of the square piles, which can reduce the amount of concrete adhering to the surface of the square piles.

[0014] Furthermore, both the upper baffle and the side baffle are hinged and locked to the frame.

[0015] The hinged design allows for easier and more reliable installation of the upper and side panels onto the frame. It also facilitates control over the locking angle between the upper and side panels and the frame, and allows for adjustment of the blocking angle of the upper and side panels, resulting in better adaptability during use.

[0016] Furthermore, it also includes a horizontal hook support, which is set horizontally and connected to the frame or baffle.

[0017] With the above-mentioned setup, the hook cross brace can reinforce the frame or baffle, and at the same time, it is convenient to move the square pile shot anchor protection frame as a whole or install it to the square pile by holding the hook cross brace, making the movement of the square pile shot anchor protection frame more convenient and labor-saving.

[0018] Furthermore, the side panel has pre-drilled holes, through which the hook bracket passes and connects to the side panel or frame.

[0019] By setting up pre-drilled holes, the tightness and connection strength between the hook cross bracket and the side panel can be improved, making the square pile shotcrete protection frame more reliable.

[0020] Furthermore, one end of the hook cross brace, located away from the center of the frame, extends to the side away from the frame and is outside the width range of the side panel.

[0021] With the above settings, it is more convenient to hold the hook horizontal support through the extended end.

[0022] Furthermore, the horizontal width of the side panel is greater than or equal to half the width of the square pile surface.

[0023] With the above setup, when two or more square pile shotcrete protection frames are used at the same time, the surface of the square pile can be covered by two adjacent sets of side panels, so that the surface of the square pile is fully protected.

[0024] Furthermore, the ends of the hook cross brackets are welded to the frame.

[0025] With the above settings, the connection between the hook cross bracket and the frame is more stable, and the connection between the various structures on the square pile shotcrete protection frame is also more stable when the square pile shotcrete protection frame moves as a whole.

[0027] Figure 2 for Figure 1 A schematic diagram of the structure of a single square pile shotcrete protection frame.

[0028] In the above attached drawings: frame 10, baffle 20, upper baffle 201, side baffle 202, reserved hole 212, hook horizontal support 30, hinge point 40, square pile 50, shotcrete area 501. Detailed Implementation

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] This embodiment is basically as follows: Figure 1 and Figure 2 As shown, this utility model embodiment proposes a square pile shotcrete protection frame, including a frame body 10, a baffle 20 and a hook horizontal support 30. The frame body 10 is rectangular and ring-shaped, and the frame body 10 encloses a shotcrete area 501. The side of the frame body 10 is directly opposite the edge of the square pile 50. The baffle 20 can be located outside the shotcrete area 501 of the frame body 10.

[0031] like Figure 2 As shown, the baffle 20 includes an upper baffle 201 and two sets of side baffles 202. The upper baffle 201 is located on the top side of the frame 10. The side baffles 202 are located at the two side edges of the frame 10. The upper baffle 201 and the side baffles 202 are hinged and locked to the frame 10. There are two hinge points 40 between the upper baffle 201 and the upper side of the frame 10, and three hinge points 40 between the side baffles 202 and the upper side of the frame 10. The width of the frame 10 is the sum of the widths of the two baffles 20, and the height is greater than or equal to 300 mm. At the same time, the horizontal width of the side baffles 202 is equal to half the surface width of the square pile 50.

[0032] At the same time, such as Figure 2 As shown, a reserved hole 212 is provided through the middle of the side panel 202, and the diameter of the reserved hole 212 is 50mm.

[0033] At the same time, such as Figure 1As shown, the horizontal hook support 30 is set horizontally. After passing through the reserved hole 212, the horizontal hook support 30 is welded to the frame 10. The horizontal hook support 30 is fixedly connected to the reserved hole 212 of the side panel 202 by bolts. One end of the horizontal hook support 30 away from the center of the frame 10 extends to the side away from the frame 10 and is located outside the width range of the side panel 202. The length of the horizontal hook support 30 away from the side panel 202 is 200mm.

[0034] In addition, the baffle 20 is supported by lightweight yet rigid materials and can utilize discarded wooden formwork or PVC billboards from the construction site.

[0035] In this embodiment, when installing the square pile shotcrete protection frame, the rods are first welded according to the outline of the shotcrete area 501 between the square piles 50 to form a frame 10 that is adapted to the range of the shotcrete area 501; then the end of the hook horizontal support 30 is welded to the middle of the side of the frame 10; then the upper baffle 201 and the side baffle 202 are hinged and installed on the frame 10, and the hook horizontal support 30 extends through the reserved hole 212 to the edge of the side baffle 202. The whole manufacturing process is convenient and low cost.

[0036] When shotcreting, two or more square pile shotcrete anchor protection frames are used simultaneously. Holding the end of the hook horizontal support 30, the square pile shotcrete anchor protection frame is transferred and fitted to the square pile 50, with the outline of the frame body 10 aligned with the shotcrete area 501. At this time, the upper baffle 201 and the side baffle 202 block the surface of the square pile 50 on both sides. Because two sets of square pile shotcrete anchor protection frames are used simultaneously for protection, ... Figure 1 As shown, the surface of a single square pile 50 can be covered by two adjacent sets of side baffles 202, thus fully protecting the surface of the square pile 50. Then, shotcrete treatment is performed on the shotcrete area 501, and the sprayed concrete can be precisely adhered to the shotcrete area 501. After the shotcrete of one shotcrete area 501 is completed, the corresponding square pile shotcrete anchor protection frame can be removed by holding the hook horizontal support 30 and transferred to another shotcrete area 501. The above procedures are repeated to complete the shotcrete construction between continuous piles.

[0037] When using two or more square pile shotcrete protection frames, after the first pile is shotcreted, the first protection frame can be removed and transferred to the third pile for reuse when the second pile is shotcreted. This cyclical and orderly process of pile shotcreting improves construction efficiency. At the same time, during shotcreting, the upper baffle 201 and the side baffle 202 can block the surface of the square pile 50, achieving the goal of not needing to clean the surface of the square pile 50 after shotcreting. This allows for safer and more economical pile shotcreting, ensuring construction progress and saving costs.
