Description

Technical Field

[0001] The utility model relates to the technical field of steel structure formwork, in particular to a movable single-side formwork device for a basement. Background Art

[0002] At present, the double-sided formwork construction method is generally used in the construction of underground space exterior walls, and the formwork is fixed with tension bolts to meet the construction requirements. However, in the case of complex construction environments, there will not be enough space outside the foundation pit to place the formwork on both sides of the wall for construction. At this time, it is necessary to adopt a single-sided formwork method for construction. Traditional single-sided formwork construction usually uses a steel pipe scaffolding oblique support system. When the wall is too high and too thick, the construction quality of this formwork support system is difficult to guarantee. The overall stability can only be improved by steel fasteners. It is easy to become unstable when facing adverse factors, causing safety accidents.

[0003] At present, the existing single-sided formwork in the construction market has a large weight, which makes it difficult to hoist it, and has poor flexibility in moving and transporting under limited space, which is not conducive to construction safety and progress.

[0004] Therefore, how to provide a movable single-sided formwork device for a basement is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] The utility model aims to provide a movable single-sided formwork device for a basement, so as to solve the problem that the flexibility of moving and carrying the single-sided formwork for the underground wall is poor under the condition of a restricted construction working environment, which is not conducive to construction safety and progress.

[0006] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0007] A movable single-side formwork device for a basement, comprising:

[0008] Anchor bolts, the embedded ends of which are cast in the basement floor;

[0009] A wall formwork system, wherein the wall formwork system is arranged perpendicular to the embedded ends of the anchor bolts;

[0010] A steel track, wherein the steel track comprises a cross-shaped structure formed by the intersection of a transverse steel track and a longitudinal steel track, and the transverse steel track and the longitudinal steel track are both provided with grooves;

[0011] A formwork frame, wherein a steel roller is provided at the bottom of the formwork frame, and the steel roller is embedded in the grooves of the transverse steel rail and the longitudinal steel rail at corresponding positions; the top of the formwork frame is detachably connected to the wall formwork system, and the bottom of the formwork frame is detachably connected to the anchor bolt on one side close to the wall formwork system.

[0012] Furthermore, it also includes jacking screws, which are respectively arranged at the ends of the transverse steel rail and the longitudinal steel rail. The jacking screws are used to adjust the horizontality of the transverse steel rail and the longitudinal steel rail, and also synchronously adjust the verticality of the formwork frame, avoiding the cumbersome steps of re-adjusting the verticality of the conventional formwork frame assembly.

[0013] Furthermore, it also includes a rail gasket, which is arranged on the bottom surface of the transverse steel rail and the longitudinal steel rail.

[0014] Furthermore, it also includes reinforcing steel pipes, and a plurality of the reinforcing steel pipes are arranged on the formwork frame at a certain interval.

[0015] Furthermore, it also includes a hydraulic power device, and each of the transverse steel rails and the longitudinal steel rails is provided with a corresponding hydraulic power device. The hydraulic power device pushes the formwork frame to the construction position, and enables the formwork frame to support the wall formwork system to maintain stability. Moreover, after the construction of a construction area is completed, the connection between the formwork frame and the wall formwork system and the anchor bolts is removed respectively, so that the formwork frame is transported to the next construction area through the hydraulic power device, and the anchor bolts and the wall formwork system are connected respectively, so as to complete the connection construction of the formwork frame.

[0016] Furthermore, it also includes an operating platform, which is arranged at the connection between the wall formwork system and the formwork frame body. Construction workers can stand on the operating platform to carry out construction.

[0017] Compared with the prior art, the beneficial technical effects of the utility model are:
