Assembly type scaffold bottom closing device

Abstract

This utility model discloses a prefabricated scaffold bottom sealing device, relating to the field of scaffolding technology. The utility model includes a support plate, a core column fixedly connected to the top of the support plate, a sealing sleeve fixedly fitted onto the core column, a column sleeve fixedly installed on the outside of the core column, and a sealing ring fixedly installed on the inner side wall of the upper end of the column sleeve. This utility model effectively seals the bottom of the scaffold support foot by inserting it between the column sleeve and the core column, using the sealing sleeve and sealing ring. The side support plates increase the contact area between the device and the ground, better preventing the bottom of the device from sinking. After use, the side support plates can be folded up around the hinge axis to reduce space occupation. By inserting rectangular limiting frames one and two into the soft, wet ground, the support plate and side support plates can be limited, better preventing lateral movement and making the scaffolding more stable.

Description

Technical Field

[0001] This utility model belongs to the field of scaffolding technology, and in particular relates to a bottom sealing device for prefabricated scaffolding. Background Technology

[0002] Scaffolding is used in the construction industry to facilitate the operation and use of construction workers during renovation and other processes. Portal scaffolding has a relatively simple structure and is used in many scenarios. However, when erecting scaffolding on soft, wet foundations, the scaffolding support legs can easily sink below the ground, causing the scaffolding to tilt, and mud and sand can easily get into the support legs, causing blockages. A search revealed that patent application number 202220587609.3 discloses a prefabricated scaffolding bottom sealing device, relating to the field of scaffolding technology. This utility model includes a three-pronged base, a sealing core assembly, a sealing sleeve, a sealing insert, and adjustable support feet. The three-pronged base includes three Z-shaped support plates whose upper ends are connected as one piece. A round tube that is inserted and fixed through the middle of the connection between the three Z-shaped support plates is fixed to fit with the bottom end of the scaffold. The sealing core assembly passes through the round tube and the sealing insert, and the lower end of the sealing core assembly is locked by a nut. The sealing sleeve is fitted on the round tube, and the bottom surface of the sealing sleeve is flush with the upper surface of the Z-shaped support plate. Several through holes that fit with the adjustable support feet are opened on the horizontal plate surface on the lower side of the Z-shaped support plate.

[0003] However, in actual use, the applicant found that the scaffolding is supported by the bottom plate, which is fixedly connected by the lower end of the bolts, and the contact area between the bottom plate and the wet and soft ground is small. Therefore, it is not possible to effectively prevent the device and the scaffolding above it from sinking easily. In view of this, we propose a prefabricated scaffolding bottom sealing device.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A prefabricated scaffold bottom enclosure device includes a support plate 1 with a large surface area to better prevent subsidence on wet and soft ground. A core column 4 is fixedly connected to the top of the support plate 1, and the lower end of the core column 4 is fixedly connected to the center of the top of the support plate 1. A sealing sleeve 41 is fitted and fixed onto the core column 4. A column sleeve 2 is fixedly installed on the outside of the core column 4, with its lower end fixedly connected to the top of the support plate 1. The column sleeve 2 and the core column 4 are coaxially arranged. The upper end of the column sleeve 2... A sealing ring 22 is fixedly installed on the inner wall of the sleeve 2. A nut sleeve 3 is threaded onto the sleeve 2. An external thread 21 that mates with the nut sleeve 3 is opened on the outer wall of the sleeve 2. A rotating handle 31 is fixedly arranged in a ring array on the peripheral wall of the nut sleeve 3. The outer end of the rotating handle 31 is provided with an anti-slip ball head to prevent slippage. A connecting ring 7 is rotatably connected to the lower outer wall of the nut sleeve 3 via a bearing. A side support plate 5 is rotatably connected to the top of the support plate 1 via a hinge shaft 6. A ring array is formed at the edge of the top of the support plate 1. A hinged support 11 is provided. A connecting seat 51 is fixedly installed on the top of the side support plate 5 near the hinged support 11. The connecting seat 51 is rotatably connected to the hinged support 11 via a hinge shaft 6. A connecting ring 7 is movably connected to the side support plate 5 via a connecting rod 8. Upper supports 71 are arranged in a ring array on the peripheral side wall of the connecting ring 7. A lower support 52 is fixedly installed on the top of the side support plate 5. Several connecting rods 8 are provided. The upper and lower ends of the connecting rods 8 are rotatably connected to a set of upper supports 71 and a set of lower supports 52 respectively via connecting shafts. By inserting the scaffold support foot between the column sleeve 2 and the core column 4, and by making the sealing sleeve 41 fit against the inner wall of the scaffold support foot and the sealing ring 22 fit against the outer wall of the scaffold support foot, the bottom of the scaffold support foot can be effectively sealed to prevent mud from entering. The side support plate 5 can increase the contact area between the device and the ground, better preventing the bottom of the device from sinking. After use, the side support plate 5 can be flipped up and folded up around the hinge axis 6 to reduce space occupation.

[0022] A rectangular limiting frame 12 is fixedly installed at the bottom of the support plate 1, and a rectangular limiting frame 53 is fixedly installed at the bottom of the side support plate 5. Both the bottom of the rectangular limiting frame 12 and the bottom of the rectangular limiting frame 53 are equipped with ground-inserting blades. By inserting the rectangular limiting frames 12 and 53 into the soft, wet ground, the support plate 1 and the side support plate 5 can be limited, which can better prevent the support plate 1 and the side support plate 5 from moving laterally and make the scaffolding more stable.

[0023] Working principle: In use, the handle 31 can be manually turned clockwise to rotate the nut sleeve 3. The rotation of the nut sleeve 3 can move the connecting ring 7 downward along the column sleeve 2. At this time, through the cooperation of the upper support 71, connecting rod 8 and lower support 52, the side support plate 5 can be rotated and unfolded downward around the hinge axis 6, so that the bottom of the side support plate 5 is flush with the bottom of the support plate 1. Then, the scaffold support foot can be inserted between the column sleeve 2 and the core column 4, so that the sealing sleeve 41 is in contact with the inner wall of the scaffold support foot, and the sealing ring 22 is in contact with the outer wall of the scaffold support foot. The device can seal the bottom of the scaffold support legs to prevent mud from entering and prevent the device from easily falling off the support legs. Then, the device can be placed on the wet and soft ground, so that the rectangular limit frame 12 and the rectangular limit frame 23 are inserted into the wet and soft ground, and the support plate 1 and the side support plate 5 are in contact with the wet and soft ground. The device can then support the bottom of the scaffold. After use, the device can be removed from the support legs at the bottom of the scaffold, and the nut sleeve 3 can be manually turned counterclockwise to drive the side support plate 5 to rotate upward around the hinge axis 6 and fold up.
