Description

Technical Field

[0001] This utility model relates to the field of external wall formwork technology, and in particular to a single-sided formwork structure for basement external walls. Background Technology

[0002] Single-sided formwork for basement exterior walls is a common formwork technique in basement construction. Its main characteristic is that formwork support is only required on one side of the wall. The advantages of this formwork structure include faster construction speed, less formwork usage, which helps shorten the construction period and reduce costs. At the same time, single-sided formwork also helps reduce the number of support frames, further improving construction safety.

[0003] The basic structure of a single-sided formwork structure for basement exterior walls includes the following parts:

[0004] Formwork: High-strength, high-rigidity formwork, such as wooden or steel formwork, is mainly used. The design of the formwork should take into account factors such as the shape of the basement, the thickness of the walls, and the properties of the concrete.

[0005] Support frame: Used to support the formwork, usually made of steel pipes or structural steel. The support frame must be fully calculated and designed to ensure its strength and stability.

[0006] Fasteners: including bolts, nuts, U-clamps, etc., used to connect the template and support frame together.

[0007] Operating platform: To facilitate construction work, an operating platform should be set up on the support frame. The operating platform can be erected using scaffolding pipes.

[0008] When constructing a single-sided formwork structure for the exterior walls of a basement, the following points should be noted:

[0009] Before construction, a detailed construction plan design and safety technical briefing should be conducted to ensure that workers understand the construction process and safe operating procedures.

[0010] The templates should be installed firmly, flat, and without warping, and the height difference between adjacent templates should not be too large.

[0011] The support frame should be erected according to the design requirements to ensure its stability and load-bearing capacity.

[0012] Before pouring concrete, the formwork and support system should be thoroughly inspected to ensure that they meet the design requirements.

[0013] During the concrete pouring process, a dedicated person should be on duty to observe the formwork and support at all times, and take immediate measures if any abnormalities are found.

[0014] In summary, single-sided formwork structure for basement exterior walls is an efficient and economical formwork technology suitable for the construction of various basement walls.

[0015] For example, Chinese utility model patent (CN219281259U) discloses a single-sided formwork structure for basement exterior walls, which solves the problems of reduced support strength caused by the small operating space in existing foundation pits, reduced formwork volume, and simplified support structure. The device includes a retaining wall formwork, which is set along the height direction of the basement exterior wall. Several support rods are set on the side of the retaining wall formwork away from the basement exterior wall, all of which are set along the height direction of the retaining wall formwork and are attached to it. Compression rods are set between the support rods, with one end connected to a support rod and the other end connected to the retaining wall formwork. A support base plate is set at the bottom of each support rod, perpendicular to the support rods and attached to the bottom surface of the foundation pit. Support feet are set on the support base plate and inserted into the bottom surface of the foundation pit. This application has the effect of improving the support strength of the formwork.

[0016] When using the above technology, the following technical problems were found in the existing technology: the device cannot flexibly adjust the support angle, resulting in poor versatility. To address this, we designed a single-sided formwork structure for the basement exterior wall to provide another technical solution to the above technical problems. Utility Model Content

[0052] The device's support structure is designed to be able to adapt to the specific shape of the exterior wall, thus improving the device's safety.

[0053] The usage process of the single-sided formwork structure for basement exterior walls provided by this utility model is as follows: When the user needs to support the exterior wall, firstly, the first motor 17 is energized and rotated. The output end of the first motor 17 drives the second bevel gear 16 to rotate. Since one side of the second bevel gear 16 is meshed with the first bevel gear 15, the rotation of the second bevel gear 16 drives the first bevel gear 15 to rotate, which in turn drives the rotating roller 14 to rotate. The rotation of the rotating roller 14 drives the screw 13 to rotate. Since the outer side of the screw 13 is threadedly connected to the threaded sleeve 12, the rotation of the screw 13 drives the threaded sleeve 12 to rise and fall, which in turn drives the rack 11 and the slider 18 to slide and rise and fall along the support block 8, causing the rack 11 to disengage from the gear 10. The user then energizes the hydraulic cylinder 2 to drive the screw 13 to rise and fall, thereby driving the installation... The first fixed rod 4 on the inner side of block 3 slides along the first rotating rod 5, thereby driving one side of the first rotating rod 5 to rise and fall. This causes the other side of the first rotating rod 5 to drive one side of the triangular plate 6 to rise and fall, which in turn causes the bottom side of the triangular plate 6 to rotate along the top of the support block 8. This allows the other side of the triangular plate 6 to adjust the angle of the support structure. The user can adjust the support angle of the support plate 21 according to the specific shape of the wall. The user can then power on the second motor 26 to rotate it. The output end of the second motor 26 drives the worm gear 24 to rotate. One side of the worm gear 24 is meshed with a worm wheel 23, so that the rotation of the worm gear 24 drives the worm wheel 23 to rotate, which in turn drives the third rotating rod 22 to rotate. The rotation of the third rotating rod 22 drives the two rotating blocks 20 to rotate, thereby adjusting the support angle of the support plate 21 and greatly improving the flexibility of the device.
