Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an adjustable foundation pit cushion support formwork. Background Technology

[0002] The foundation pit cushion layer includes a bottom wall cushion layer and a peripheral wall cushion layer. Formwork structures are required during the construction of the foundation pit cushion layer. Utility model patent CN207760868U discloses a formwork system for inclined cushion layers under column foundations, specifically disclosing a fixed steel formwork and a support device. The fixed steel formwork is fixed to the support device, parallel to the inclined sidewall of the foundation pit with a gap. Each support device includes a concrete block, a vertical screw inserted into the concrete block, and a nut. The vertical screw passes through the horizontal bottom frame and the concrete block from top to bottom, with its lower end inserted into the bottom of the foundation pit and its upper end protruding from the concrete block. The nut threads the fixed steel formwork and the vertical screw together. The fixed steel formwork is composed of multiple steel mold bodies assembled together, with adjacent steel mold bodies detachably connected by bolts. The aforementioned patent uses vertical screws and nuts to fix the shaped steel template. Its tilt angle is fixed and cannot be freely adjusted. In addition, the steel template body is connected by bolts, which is inconvenient to disassemble and assemble and is inefficient. Utility Model Content

[0003] To address the technical problems in the prior art, this utility model provides an adjustable foundation pit cushion support template, including a template assembly and a fixing frame. The template assembly is parallel to and spaced apart from the perimeter wall of the foundation pit. The fixing frame is installed inside the foundation pit and fixedly connected to the bottom wall of the foundation pit. The bottom end of the template assembly is hinged to the bottom end of the fixing frame. The module also includes an adjustment component, which is connected to both the template assembly and the fixing frame, with the connection position located at the top end of both components. The template assembly rotates around the hinge point under the influence of the adjustment component. The template assembly includes multiple template units and a locking mechanism. Each template unit has a connecting pin on one side and a connecting hole on the opposite side that engages with the connecting pin. When the connecting pin engages with the connecting hole, two adjacent template units are fixed by the locking mechanism.

[0004] Furthermore, the adjustment assembly includes a hydraulic rod, which is horizontally mounted on the fixed frame, and the telescopic end of the hydraulic rod is hinged to the template assembly.

[0005] Furthermore, the telescopic end of the hydraulic rod is provided with scale lines.

[0006] Furthermore, the locking mechanism includes a fixing pin, a spring, a connecting ring, and a connecting post. The fixing pin and the connecting post are both fixedly installed on the side of the template assembly near the fixing frame, and the fixing pin and the connecting post are respectively near the two side edges. One end of the spring is hinged to the fixing pin, and the other end is fixedly connected to the connecting ring. When the connecting ring and the connecting post are engaged, the spring is in a stretched state.

[0007] Furthermore, the connecting post is provided with a slot, the size of which is larger than the size of the connecting ring.

[0008] Furthermore, a counterweight is provided at the end of the fixing frame away from the template assembly.

[0009] Beneficial effects: 1. This utility model improves the stability of the template assembly by setting up the template assembly, fixing frame and adjusting assembly, and facilitates the adjustment of the tilt angle between the template assembly and the bottom wall of the foundation pit. The setting of connecting pin, connecting hole and locking mechanism can facilitate the quick and easy assembly and disassembly of the template assembly, thus improving efficiency.

[0010] 2. In this utility model, the tilt angle can be adjusted by using the extension of the hydraulic rod through the setting of the hydraulic rod; combined with the setting of the scale dimension line, the tilt angle of the template component can be accurately calculated. Specifically, if the tilt angle is set as A, then the tangent of A-90° is equal to the extension length of the hydraulic rod / the installation height of the hydraulic rod.

[0011] 3. In this utility model, the relative movement of the two template units can be restricted by the setting of the fixing pin, spring, connecting ring and connecting post, so as to quickly and easily fix the two template units. Specifically, when the connecting pin and the connecting hole are engaged, the spring is stretched by external force to make the connecting ring engage with the connecting post. When the external force is removed, the two template units can be tightly fitted together under the action of the spring to prevent the two template units from separating. When disassembly is required, the connecting ring can be removed from the connecting post by external force. The setting of the slot can limit the connection ring to prevent the connection ring from detaching from the connecting post.

[0012] 4. The use of counterweights in this invention improves the stability of the fixing frame, thereby further ensuring the firmness of the template assembly installation. Attached Figure Description

[0022] This utility model provides an adjustable foundation pit cushion layer support template, such as... Figures 1 to 4As shown, the structure includes a template assembly 1, an adjusting assembly, and a fixing frame 2. The template assembly 1 is parallel to and spaced apart from the perimeter wall of the foundation pit 3. The fixing frame 2 is installed inside the foundation pit 3 and fixedly connected to the bottom wall of the foundation pit 3. The bottom end of the template assembly 1 is hinged to the bottom end of the fixing frame 2. To ensure the stability of the fixing frame 2, a counterweight 8 can be set at the end of the fixing frame 2 away from the template assembly 1. The template assembly 1 is rotated around the hinge point under the drive of the adjusting assembly. The fixing frame 2 may include one or more. When there is only one, the fixing frame 2 is equipped with a template assembly. In the middle of component 1, when there are multiple fixing brackets 2, multiple fixing brackets 2 are symmetrically arranged about the center line of template component 1. The specific number of fixing brackets 2 can be determined according to the length of template component 1. By setting multiple fixing brackets 2, the stability of angle adjustment can be improved. The template component 1 includes multiple template units 11 and a locking mechanism 12. One side of the template unit 11 is provided with a connecting pin 4, and the opposite side is provided with a connecting hole 5 that cooperates with the connecting pin 4. When the connecting pin 4 cooperates with the connecting hole 5, two adjacent template units 11 are fixed by the locking mechanism 12.

[0023] In this embodiment, the template assembly 1, the fixing frame 2 and the adjustment component are provided to improve the firmness of the template assembly 1 and facilitate the adjustment of the tilt angle between the template assembly 1 and the bottom wall of the pit 3. The template assembly 1 can be easily and quickly assembled and disassembled by the connecting pin 4, the connecting hole 5 and the locking mechanism 12, thereby improving efficiency.

[0024] In this utility model, such as Figure 1 , Figure 2 As shown, the adjustment assembly includes a hydraulic rod 6, which is horizontally mounted on the fixed frame 2, and the telescopic end of the hydraulic rod 6 is hinged to the template assembly 1; the telescopic end of the hydraulic rod 6 is provided with scale lines.

[0025] In this embodiment, the hydraulic rod 6 can be used to adjust the tilt angle by extending it. Specifically, when the hydraulic rod 6 is not moving, the template assembly 1 is perpendicular to the bottom wall of the pit 3 at a right angle. When the hydraulic rod 6 extends, the tilt angle of the template assembly 1 is an obtuse angle. Combined with the setting of the scale line, the tilt angle of the template assembly 1 can be accurately calculated. Specifically, if the tilt angle is A, then the tangent of A-90° is equal to the extension length of the hydraulic rod 6 / the installation height of the hydraulic rod 6, where the installation height is a constant value and can be directly obtained. The extension length of the hydraulic rod 6 can be directly read from the scale line.

[0026] In this utility model, such as Figure 1 , Figure 4As shown, the locking mechanism 12 includes a fixing pin 121, a spring 122, a connecting ring 123, and a connecting post 124. The fixing pin 121 and the connecting post 124 are both fixedly installed on the side of the template assembly 1 near the fixing frame 2, and the fixing pin 121 and the connecting post 124 are respectively near the two side edges. One end of the spring 122 is hinged to the fixing pin 121, and the other end is fixedly connected to the connecting ring 123. When the connecting ring 123 cooperates with the connecting post 124, the spring 122 is in a stretched state. The connecting post 124 is provided with a slot 7, and the size of the slot 7 is larger than the size of the connecting ring 123.

[0027] In this embodiment, the relative movement of the two template units 11 can be restricted by the setting of the fixing pin 121, spring 122, connecting ring 123 and connecting post 124, so as to quickly and easily fix the two template units 11. Specifically, when the connecting pin 4 and the connecting hole 5 are engaged, the spring 122 is stretched by external force, so that the connecting ring 123 is sleeved with the connecting post 124. When the external force is removed, the two template units 11 can be tightly fitted together under the action of the spring 122, so as to prevent the two template units 11 from separating. When disassembly is required, the connecting ring 123 can be removed from the connecting post 124 by external force. The setting of the slot 7 can limit the connection ring 123 and prevent the connection ring 123 from detaching from the connecting post 124.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
