A building formwork stabilising support device

Abstract

This utility model relates to the field of building formwork technology, specifically a stable support device for building formwork, including a base, with a guide sleeve fixedly connected to the center of the top surface of the base. The advantages of this utility model are: by releasing the limiting ratchet rack through the clamping assembly, the lifting sleeve can be quickly pulled up and down, achieving rapid height adjustment. Simultaneously, rotating the lifting sleeve further drives the threaded top rod upwards to tighten, achieving rapid and stable clamping and improving adjustment efficiency. Rotating the first rotating handle drives the drive worm gear to rotate, which in turn drives the transmission worm wheel to rotate. Then, the rotating shaft drives the transmission gear to rotate, which in turn drives the driven gear to rotate, causing the threaded sleeve to rotate and the threaded top rod to rise and fall, thus tightening the support base upwards. Simultaneously, rotating the second rotating handle drives the drive gear to rotate, which in turn drives the driven rack, causing the clamping teeth to extend and retract, achieving clamping and loosening for rapid height adjustment.

Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, and in particular to a building formwork stabilization support device. Background Technology

[0002] The formwork structure mainly consists of three parts: the panel, the supporting structure, and the connectors. The panel is the load-bearing plate that directly contacts the freshly poured concrete. The supporting structure is a temporary structure that supports the panel, the concrete, and the construction load, ensuring that the formwork structure is firmly assembled and does not deform or break. The connectors are the accessories that connect the panel and the supporting structure into a whole.

[0003] Chinese utility model CN215368707U discloses a support device for building formwork. This support device features a threaded connection between a sleeve and a threaded ring, facilitating installation and separation of the threaded ring and sleeve. The sleeve is fitted onto a rod, and the rod is connected to a support plate via a locking block on the inner wall of a connecting ring engaging with slots on both sides of the top of the rod, facilitating installation and separation of the support plate and the rod. This makes the entire support device easy to install and disassemble, simplifying transportation and reducing space occupation when not in use. However, this support device for building formwork still has the following problems in use:

[0004] The support device for this building formwork uses a screw-driven slider to raise and lower, which in turn raises and lowers the sleeve rod, thus adjusting the support height. However, the screw drive is relatively slow, so it takes a long time to tighten, which affects the adjustment efficiency. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to provide a stable support device for building formwork to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of this utility model provides a stabilizing support device for building formwork, including a base. A guide sleeve is fixedly connected to the center of the top surface of the base. Guide strip holes are opened at the center of both sides of the guide sleeve. A lifting sleeve is slidably connected to the inner wall of the guide sleeve. Guide seats are fixedly connected to the center of both sides of the bottom of the lifting sleeve. Both guide seats are slidably connected to the guide strip holes. A limiting ratchet is fixedly connected to the outer wall of the guide sleeve near the edge of the guide strip hole. A clamping component is provided inside one of the two guide seats near the limiting ratchet. The guide seat is clamped and fixed to the limiting ratchet by the clamping component. A threaded sleeve is rotatably connected to the center of the top of the lifting sleeve. A guide slider is slidably connected to the inner wall of the lifting sleeve. A threaded top rod is fixedly connected to the center of the top surface of the guide slider. A support seat is fixedly connected to the top of the threaded top rod. The threaded top rod is threadedly connected to the threaded sleeve.

[0008] Preferably, in any of the above schemes, a rotating shaft is rotatably connected to the inner side of one of the two guide seats on the side away from the limiting ratchet. The rotating shaft extends through the top surface of the lifting sleeve. A transmission gear is fixedly connected to the top end of the rotating shaft. A driven gear is fixedly connected to the outer wall of the threaded sleeve. The transmission gear and the driven gear are meshed together.

[0009] The technical effect achieved by adopting the above solution is that the transmission gear and the driven gear mesh and connect. The rotation of the transmission gear drives the driven gear to rotate, which in turn drives the threaded sleeve to rotate, so as to drive the threaded push rod to rise and fall.

[0010] Preferably, in any of the above embodiments, a drive worm is rotatably connected to the side of the guide seat near the rotating shaft, a transmission worm wheel is fixedly connected to the bottom of the rotating shaft, the drive worm is meshed with the transmission worm wheel, and a first rotating handle is fixedly connected to one end of the drive worm.

[0011] The technical effect achieved by adopting the above solution is that by rotating the first rotating handle, the drive worm can be driven to rotate, which in turn drives the transmission worm wheel to rotate.

[0012] Preferably, in any of the above embodiments, the clamping assembly includes clamping teeth slidably connected inside the guide seat, a driven rack fixedly connected to the top of one side of the clamping teeth, a second rotating handle rotatably connected to the center of the inner wall of the guide seat, a drive gear fixedly connected to one side of the central shaft of the second rotating handle, and the drive gear meshing with the driven rack.

[0013] The technical effect achieved by adopting the above solution is that by rotating the second rotating handle, the drive gear can be rotated, which in turn drives the driven rack, causing the locking teeth to extend and retract, thereby achieving locking and unlocking, so as to quickly adjust the height.

[0014] Preferably, in any of the above embodiments, the clamping assembly further includes a push spring disposed inside the guide seat, the push spring being located on one side of the driven rack and inside the guide seat, and the clamping teeth clamping the limiting ratchet rack under the push of the push spring.

[0015] The technical effect achieved by adopting the above solution is that by pushing the spring, the locking teeth can be automatically pushed to lock, thus achieving automated locking and fixing.

[0016] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0017] 1. This building formwork stabilizing support device can quickly pull the lifting sleeve to raise or lower its height by releasing the limiting ratchet rack through the clamping component, thus achieving rapid height adjustment. At the same time, by rotating the lifting sleeve, the threaded top rod can be further driven to tighten upwards, achieving rapid and stable clamping and improving adjustment efficiency.

[0018] 2. This building formwork stabilizing support device, by rotating the first rotating handle, can drive the drive worm gear to rotate, which in turn drives the transmission worm wheel to rotate. Then, through the rotating shaft, it drives the transmission gear to rotate, which drives the driven gear to rotate, which drives the threaded sleeve to rotate, and drives the threaded top rod to rise and fall, thereby making the support seat press upward. At the same time, by rotating the second rotating handle, it can drive the drive gear to rotate, which drives the driven rack, causing the locking teeth to extend and retract, realizing locking and unlocking, so as to quickly adjust the height.
