Description

Technical Field

[0001] This utility model relates to the field of building support technology, and more specifically, to an adjustable support frame for construction. Background Technology

[0002] In water conservancy engineering construction, pit wall support structure is a temporary support structure used to reinforce the walls of excavated pits, trenches or slopes, preventing pit wall collapse and ensuring construction safety and stability of the working space.

[0003] For example, publication number CN114775983A, "Support Frame for Construction of Water Conservancy and Hydropower Projects," relates to the field of construction technology for water conservancy and hydropower projects. It solves the problems of poor support stability, cumbersome height adjustment, inability of workers to adjust the overall height on the support frame, and difficulty in transportation. It can provide good protection for workers, facilitate workers to quickly adjust the overall height, effectively improve the stability of the device, and workers can adjust the height of the device at the top of the support frame, making it convenient for movement and transportation.

[0004] When the support frame extends to both sides, it is impossible to extend one side independently during the synchronous extension process. This results in uneven stress during the support process, making it difficult to maintain stable support. Furthermore, the direction of the moving components of the support frame is difficult to adjust, which limits the extension direction and area of ​​the support frame and makes it difficult to adapt to the specific location requirements of the construction area.

[0005] Therefore, an adjustable support frame for construction is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable support frame for construction to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable support frame for construction, comprising a support frame structure and a movable adjustment extension frame. The support frame structure includes a movable adjustment extension structure, a mounting frame, and a central extension frame. Two sets of movable adjustment extension structures are provided, and a support frame is connected above the two sets of movable adjustment extension structures. A central extension frame connects the support frames.

[0008] Preferably, the movable adjustment extension structure includes an extension bracket, a first lifting frame, and a movable component. The first lifting frame is bolted between the two sets of extension brackets, and a movable component is installed below each extension bracket on the side away from the first lifting frame.

[0009] Preferably, the movable component includes a rotating base, a set of wheels, and a second lifting frame. Each rotating base has a set of wheels at its lower end, and the second lifting frame is located between the two sets of wheels. A swing engagement seat is installed on the lower end face of the rotating base and the upper end face of the wheels. The rotating base and the wheels are movably connected by the swing engagement seat, and a limit stop is installed between the two sets of wheels.

[0010] Preferably, a mounting bracket is installed at the top of the movable component, drive placement holes are provided on both sides of the mounting bracket, a rotating disk is installed above the mounting bracket, and a placement cavity is reserved inside the rotating base.

[0011] Preferably, the extension bracket has an external extension rod slidably connected inside, and the top of the external extension rod is bolted to a shaft mounting base. Both sides of the shaft mounting base are equipped with mating mounting holes.

[0012] Preferably, a fixed support rod and a bottom extension rod are respectively installed at the top and one side of the shaft mounting base, and a top extension rod is installed at the top of the fixed support rod.

[0013] Preferably, the central extension frame includes a first support rod, a placement seat, and a second support rod. The placement seat is slidably connected to the side of the first support rod, and the second support rod is provided on the side of the placement seat away from the first support rod.

[0014] Preferably, a screw is connected to the lower part of the first lifting frame, and a grounding block is installed below the screw. The first lifting frame and the second lifting frame have the same structure.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Compared with existing technologies, this adjustable support frame for construction has several advantages in use. First, the extension direction and range are controllable. Through the cooperation of the rotating base and the driving wheels in the moving component, the direction of the driving wheels can be manually changed. Combined with the sliding extension structure of the extension bracket and the outward extension rod, it can expand to both sides simultaneously or adjust the extension area on one side individually to meet the support and coverage needs of different construction areas. Furthermore, both the first and second lifting frames support manual or electric drive. The overall lifting is achieved by moving the screw, which facilitates lowering the center of gravity during movement and allows the moving component to be lifted to separate from the ground during operation, ensuring support stability.

[0017] Compared with existing technologies, this adjustable support frame for construction can still be adjusted according to the construction environment during the construction process through the moving wheels and lifting structure of the movable components. The support range can be adjusted at any time according to the changes in the construction point, without the need for overall disassembly and reassembly, which can improve construction efficiency. Furthermore, the adjustable effect of the support structure allows the support frame to adapt to the support of narrow spaces and meet the expansion needs of large-area construction, making it better able to handle complex construction environments.

During the extension process, the support frame structure 1 includes the movable adjustable extension structure 2, a mounting frame, and a central extension frame 4. Two sets of movable adjustable extension structures 2 are provided, allowing the support frame structure 1 to extend on both sides simultaneously, thus facilitating stable support of the support frame. Support frames 3 are connected above the two sets of movable adjustable extension structures 2, and the central extension frame 4 connects the support frames 3. During the extension of the support frame structure 1, the connected central extension frame 4 provides additional support to the support frame structure.

[0027] In a preferred embodiment, the movable adjustment extension structure 2 includes an extension bracket 11, a first lifting frame 12, and a movable component 24. The extension bracket 11 can extend simultaneously with the support frame structure 1. The direction of movement of the movable component 24 in the movable adjustment extension structure 2 can be adjusted by changing the direction of movement. The first lifting frame 12 is bolted between the two sets of extension brackets 11. The movable component 24 is installed on the lower side of the extension bracket 11 away from the first lifting frame 12. This allows the extension area of ​​the support frame structure 1 to be adjusted at any time according to the specific location in the construction area during the construction process.

[0028] In a preferred embodiment, the movable component 24 includes a rotating base 14, casters 15, and a second lifting frame 16. Casters 15 are located below the rotating base 14, and the rotating base 14 is connected to the casters 15, driving them to rotate. The first lifting frame 12 and the second lifting frame 16 can be manually or electrically driven to move the screws 1201 within them. During this movement, the screws 1201 move the support frame structure 1 and the movable component 24 upwards, causing the movable component 24 to separate from the ground. The two sets of casters 15... A second lifting frame 16 is provided between the two. A swing locking seat 22 is installed on the lower end face of the rotating base 14 and the upper end face of the moving wheel 15. The rotating base 14 and the moving wheel 15 are movably connected through the swing locking seat 22. A limit stop 23 is installed between the two sets of moving wheels 15. Then, through the rotating disk 20 structure, the walking direction of the moving component 24 can be manually changed by the bearing of the rotating disk 20 structure, so that the first lifting frame 12 and the second lifting frame 16 can support the support frame structure 1 by lifting, and at the same time adjust the extension direction of the support frame structure 1 by changing the direction of the moving component 24.

[0029] In a preferred embodiment, a mounting bracket 19 is installed at the top of the moving component 24. Both sides of the mounting bracket 19 are provided with drive placement holes 1901. The mounting bracket 19 can be connected to the fixed support rod 5 and the bottom extension rod 6. The drive placement holes 1901 are holes for controlling the second lifting frame 16 to drive it. A hand crank or motor can be connected at any time to drive the screw 1201 to move. A rotating disk 20 is installed above the mounting bracket 19. The rotating base 14 has a reserved placement cavity 21 inside.

[0030] In a preferred embodiment, the extension bracket 11 is internally slidably connected to an outward extension rod 13, and the extension bracket 11 can be unfolded through the outward extension rod 13, which can be unfolded in conjunction with the rod of the support frame structure 1. The top of the outward extension rod 13 is bolted to a shaft mounting base 17, and both sides of the shaft mounting base 17 are equipped with mating mounting holes 18.

[0031] In a preferred embodiment, a fixed support rod 5 and a bottom extension rod 6 are respectively installed on the top and one side of the shaft mounting base 17. When the movable adjustment extension structure 2 drives the support frame structure 1 to unfold, a top extension rod 7 is installed on the top of the fixed support rod 5. The extension structure of the fixed support rod 5 and the bottom extension rod 6 is achieved by sleeved rod structures at both ends of the sleeve structure, which can move and unfold in two directions at the same time, and can also unfold in one direction while the other side remains stationary.

[0032] In a preferred embodiment, the central extension frame 4 includes a first support rod 8, a placement seat 9, and a second support rod 10. The placement seat 9 is slidably connected to the side of the first support rod 8, and the support frame structure 1 is reinforced by the central extension frame 4 structure. When the support frame structure 1 is extended, the second support rod 10 is provided on the side of the placement seat 9 away from the first support rod 8. It can move within the placement seat 9 through the first support rod 8 and the second support rod 10, thereby providing support while extending.

[0033] In a preferred embodiment, a screw 1201 is connected to the lower part of the first lifting frame 12, and a grounding block 1202 is installed below the screw 1201. The first lifting frame 12 and the second lifting frame 16 have the same structure.

[0034] In this embodiment, the first lifting frame 12 and the second lifting frame 16 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them and have not made any structural or functional improvements. We will not go into detail here.

[0035] The working process of this utility model is as follows: When supporting the construction area, the support frame structure 1 and the movable adjustment extension structure 2 work together to allow the support frame structure 1 to support both sides simultaneously. This allows the support frame structure 1 to extend on both sides simultaneously during the extension process, thus facilitating the stable support of the support frame. During the extension of the support frame structure 1, the connected middle extension frame 4 can provide additional support to the support frame structure. The extension bracket 11 can extend simultaneously with the support frame structure 1. By changing the direction of movement of the movable component 24 in the movable adjustment extension structure 2, the direction of movement can be adjusted, so that the extension area of ​​the support frame structure 1 can be adjusted at any time according to the specific location in the construction area during the construction process.

[0036] The rotating base 14 is connected to the moving wheel 15, which drives the moving wheel 15 to rotate. The first lifting frame 12 and the second lifting frame 16 can be driven manually or electrically to move the screw 1201 in the first lifting frame 12 and the second lifting frame 16. During the movement, the screw 1201 moves the support frame structure 1 and the moving component 24 upward, so that the moving component 24 is separated from the ground. Then, through the rotating disk 20 structure, the direction of movement of the moving component 24 can be changed manually by the bearing of the rotating disk 20 structure. This allows the first lifting frame 12 and the second lifting frame 16 to support the support frame structure 1 by lifting, and at the same time, the extension direction of the support frame structure 1 can be adjusted by changing the direction of the moving component 24.

[0037] Furthermore, its mounting bracket 19 can be connected to the fixed support rod 5 and the bottom extension rod 6, and the provided drive placement hole 1901 is a hole for controlling the second lifting frame 16 to drive it. It can be connected to a hand crank or motor at any time to drive the screw 1201 to move. The extension frame can be unfolded through the outward extension rod 13, and can be unfolded in conjunction with the rod of the support frame structure 1. Then, when the moving adjustment extension structure 2 drives the support frame structure 1 to unfold, it can move and unfold in two directions at the same time, and can also unfold in one direction while the other side remains stationary.

[0038] The support frame structure 1 is reinforced by the middle extension frame 4 structure. When the support frame structure 1 is extended, it can move within the placement seat 9 through the first support rod 8 and the second support rod 10, thereby extending and supporting at the same time.
