[0038] Example:

[0039] This embodiment provides a slipform device for concrete construction between guard piles, which is used to solve the technical problem of uneven concrete surface between guard piles in the prior art. The slipform device for concrete construction between guard piles includes a slide rail 1, a slider 2, a positioning assembly 3 and a plate 4, wherein:

[0040] In the working state, a slide rail 1 is installed on each guardrail pile 5, and the extension direction of the slide rail 1 is the axial direction of the guardrail pile 5, that is, the axial direction of the guardrail pile 5 is the length direction of the slide rail 1. Through the detachable slide rail 1, when the concrete pouring between the guardrail piles 5 is completed, the slide rail 1 is removed from the guardrail pile 5 and moved to the next construction site for use. In this way, the slide rail 1 can be reused, saving construction costs.

[0041] A slider 2 is installed on each slide rail 1 , so that the position of the slider 2 on the slide rail 1 can be easily adjusted by sliding the slider 2 installed.

[0042] The positioning assembly 3 is installed between the slider 2 and the slide rail 1. The positioning assembly 3 and the slider 2 are arranged one by one. The positioning assembly 3 is used to fix the slider 2. In this way, the slider 2 can be easily fixed in the slide rail 1 through the arrangement of the positioning assembly 3.

[0043] The plate body 4 can be detachably mounted on two adjacent sliders 2. Thus, after the plate body 4 is mounted on two adjacent retaining piles 5 through the sliders 2, concrete is poured, so that the surface of the concrete is smoother and the thickness is more uniform.

[0044] Through the above structure, when it is necessary to spray concrete between the retaining piles 5, the slide rail 1 is first installed on each retaining pile 5, and then the slider 2 is slidably installed in the slide rail 1, and then the plate body 4 is installed on the slider 2 on two adjacent retaining piles 5, and finally the slider 2 is fixed to the slide rail 1 through the positioning component 3, and the above process is repeated until the plate body 4 covers all the retaining piles 5 in the foundation pit of this layer, and finally the concrete pouring is carried out. In this way, through the setting of the plate body 4, the thickness of the concrete pouring is more uniform and the surface is smoother, and the concrete rebound is avoided at the same time. Through the setting of the slider 2, it is more convenient to adjust the position of the plate body 4 installed on the slider 2. This allows the plate body on the same retaining pile 5 to fit more compactly, and the next layer of foundation pit excavation is carried out after the concrete reaches the design strength requirement. After excavation to the next layer, the slide rails 1 on the upper and lower layers are connected. When the positioning assembly 3 is opened, the slider 2 can slide directly from the upper slide rail 1 to the lower slide rail 1, which is convenient and quick. Therefore, through the arrangement of the plate body 4, the slipform device for concrete construction between retaining piles provided by the utility model makes the surface of the concrete smoother and the thickness more uniform when pouring concrete, avoiding secondary finishing and concrete rebound, thereby reducing concrete consumption, and further reducing the amount of work and construction costs.

[0045] An optional implementation of this embodiment is as follows: the slide rail 1 has a first through hole 11 and a second through hole 12, the first through hole 11 and the second through hole 12 are connected, and the first through hole 11 and the second through hole 12 are arranged along a first direction, and the first direction and the extension direction of the slide rail 1 are perpendicular to each other.

[0046] The slider 2 is slidably installed in the second through hole 12, and one end of the slider 2 extends into the first through hole 11, and the other end of the slider 2 extends out of the second through hole 12. In this way, through the setting of the second through hole 12, the slider 2 can move on the slide rail 1 along the length direction of the slide rail 1.

[0047] An optional implementation of this embodiment is as follows: the positioning assembly 3 includes a wing plate 31 and a screw rod 32, wherein:

[0048] There are two wing plates 31 , which are fixedly mounted on opposite sides of the slider 2 and located at one end of the slider 2 extending into the first through hole 11 . Thus, the slider 2 is prevented from falling off the front end of the slide rail 1 by the arrangement of the wing plates 31 .

[0049] A threaded through hole is formed at one end of the slider 2 extending from the second through hole 12 , and one end of the screw rod 32 is screwed into the threaded through hole and extends into the first through hole 11 .

[0050] The first and second cams 32 are in the state of being pressed against the top of the support rail 11, and the second cams 32 are in the state of being pressed against the top of the support rail 11. When the slider 2 needs to be fixed on the slide rail 1, it is only necessary to rotate the screw rod 32 so that the end of the screw rod 32 extending into the first through hole 11 moves in a direction gradually approaching the retaining pile 5 until the end of the screw rod 32 extending into the first through hole 11 abuts against the first inner side wall. In this way, the side of the two wing plates 31 away from the retaining pile 5 abuts against the second inner side wall, thereby achieving the purpose of fixing the slider 2. When the slider 2 needs to be loosened, it is only necessary to rotate the screw rod 32 in the opposite direction so that the end of the screw rod 32 extending into the first through hole 11 moves in a direction gradually away from the retaining pile 5 until the end of the screw rod 32 extending into the first through hole 11 separates from the first inner side wall. In this way, the side of the two wing plates 31 away from the retaining pile 5 separates from the second inner side wall, thereby achieving the purpose of loosening the slider 2.

[0051] Optionally, a pad 33 is further included, which is detachably mounted on one end of the screw 32 extending into the first through hole 11. In this way, by setting the pad 33, when the slider 2 is fixed, the screw 32 is prevented from wearing the slide rail 1, thereby extending the service life of the slide rail 1.

[0052] Optionally, the pad 33 is bonded to one end of the screw rod 32 extending into the first through hole 11 , and the bonded pad 33 makes it easier to disassemble and assemble the pad 33 .

[0053] Optionally, a handle 34 is further included, which is installed at the end of the screw 32 away from the pad 33, that is, the handle 34 is installed at the end of the screw 32 extending out of the second through hole 12. In this way, the setting of the handle 34 makes it easier to rotate the screw 32 and slide the slider 2.

[0054] An optional implementation of this embodiment is as follows: the plate body 4 includes a mounting plate 41 and a connecting plate 42, wherein:

[0055] There are two mounting plates 41 , and the two mounting plates 41 are detachably mounted on opposite sides of the slider 2 .

[0056] Both ends of the connecting plate 42 are fixedly installed on two mounting plates 41 respectively, that is, the plate body 4 is in a U shape. Through the arrangement of the mounting plates 41, it is more convenient to install the plate body 4 on the slider 2. Through the arrangement of the connecting plate 42, the plane of the concrete is made more flat.

[0057] Optionally, the mounting plate 41 is installed on the slider 2 by screws. In this way, the mounting plate 41 installed by screws is more convenient for disassembling and assembling the plate body 4.

[0058] Optionally, the plate body 4 is a structural member made of steel. Steel has high strength, good plasticity and toughness, and is corrosion-resistant, with a long service life.

[0059] An optional implementation manner of this embodiment is as follows: The slide rail 1 is installed on the retaining pile 5 by expansion bolts. The slide rail 1 installed by expansion bolts is more convenient for disassembling and assembling.

[0060] The specific implementation manners described above further elaborate on the purpose, technical solutions, and beneficial effects of the present utility model. It should be understood that the above are only the specific implementation manners of the present utility model and are not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
