Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an easily removable formwork support device for confined spaces. Background Technology

[0002] During the construction process, it is often necessary to build air ducts in buildings. Air ducts are channels or pipe systems in buildings or facilities used to transport air. They are widely used in heating, ventilation and air conditioning systems to regulate and distribute indoor air, ensure indoor air circulation, temperature regulation and air quality control. Formwork support devices are often required during the construction of air ducts.

[0003] A removable formwork support device for confined spaces, disclosed in patent publication number CN215803233U, comprises multiple support units equidistantly distributed. Each support unit includes a base plate with two telescopic rods fixedly connected to its upper surface. A top plate is fixedly connected to the upper surfaces of the two telescopic rods. Two vertical plates abut against the side walls of the top plates on the left and right sides, respectively. The vertical plates are secured to the side walls of the top plates with two fixing bolts, ensuring a firm fixation and easy assembly / disassembly. A horizontal plate provides support from the bottom. The base plate and top plate are supported and fixed by two telescopic rods, which are extendable and retractable, allowing for adjustment of the support height according to actual requirements. This improves construction efficiency and quality, solving the problems of existing formwork support devices for confined spaces being inconvenient to assemble and disassemble, complex to operate, having weak structural load-bearing capacity, and poor support effect, thus affecting overall construction efficiency and quality.

[0004] The aforementioned and similar support devices use telescopic rods for support. When supporting a large area, multiple telescopic rods are required. Such support devices for confined spaces are often used in the construction of air ducts. After the air duct is completed, in order to ensure smooth airflow, the support device needs to be removed. The aforementioned and similar support devices are cumbersome to disassemble and install, which is not conducive to improving the efficiency of disassembly and assembly. Therefore, this application is made. Summary of the Invention

[0005] The purpose of this utility model is to provide an easily removable formwork support device for confined spaces, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easily removable template support device for confined spaces, comprising a main board and a foldable support mechanism mounted on the main board. The main board is equipped with a locking mechanism for keeping the support mechanism in a supported state at all times. The locking mechanism includes a lifting component and an air supply component. The air supply component provides power to cooperate with the lifting component to keep the support mechanism in a supported state at all times. Connection mechanisms for connecting with other main boards are installed on the outer walls at both ends of the main board.

[0007] Furthermore, the support mechanism includes main blocks installed at both ends of the top outer wall of the motherboard, a rotatable first rotating column installed in the main block, side plates installed on both sides of the outer wall of the first rotating column, a support plate provided on the top outer wall of the motherboard, second rotating columns installed on both ends of the outer wall of the support plate, and the top of the side plates rotatably connected to the second rotating columns.

[0008] Furthermore, the lifting assembly includes a slot on the top outer wall of the main board located at the bottom of the main block, an airbag installed in the slot, a top plate installed on the top outer wall of the airbag, a locking post installed on the top outer wall of the top plate, a locking groove corresponding to the locking post on the bottom outer wall of the main block, the locking groove extending through to the first rotating post, and the locking support mechanism being in a supported state is completed by the locking post being inserted into the locking groove on the first rotating post, and an impact piece is embedded in the locking groove on the first rotating post.

[0009] Furthermore, the air supply assembly includes a pump mounted on the top outer wall of the motherboard, and an air pipe connected to the pump is installed between the two airbags in the motherboard.

[0010] Furthermore, a pressure sensor is installed inside the airbag, and air valves are installed on the outer walls at both ends of the air tube.

[0011] Furthermore, the connection mechanism includes a plug block installed on the outer wall of the other end of the motherboard. A slot corresponding to the plug block is provided on the outer wall of one end of the motherboard. Vertical grooves are provided at both ends of the top inner wall of the slot and the top outer wall of the plug block, and limit pins are inserted into the vertical grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This easily removable formwork support device for confined spaces provides continuous support for the air duct formwork through a combination of support and locking mechanisms. The foldable support mechanism facilitates easy installation and disassembly, enabling quick installation and disassembly of the entire device in confined spaces. It also reduces the overall space occupied during transportation. The connecting mechanism allows connection to other main boards to meet the support needs of formwork of different lengths and adapt to various support scenarios. Furthermore, the support mechanism on each main board is an independent structure, reflecting a modular design that facilitates replacement and maintenance by subsequent maintenance personnel.

[0013] Meanwhile, the air pressure sensor can monitor the air pressure inside the airbag, record the air pressure when the support mechanism is locked and released, and control the air in and out through the air valve so that the pump does not need to be in working state all the time, thus extending the service life of the pump. A horizontal groove can be opened on one side of the outer wall of the support plate to make the support plate lighter, and reinforcing ribs can be added to the horizontal groove to ensure the strength of the support plate.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The easily removable formwork support device for confined spaces is a piece of equipment used in building construction to support formwork. It is specifically designed for use in narrow or restricted spaces. Support devices are required during the construction of ventilation ducts. The support device provided by this utility model is specifically used for formwork support operations in confined spaces during building construction. When using this device for support operations, it is necessary to ensure that the components requiring power are powered in advance to ensure the normal operation of the device.

[0018] like Figures 1-4As shown, this utility model provides a technical solution: an easily removable template support device for narrow spaces, including a main board 1 and a foldable support mechanism 2 installed on the main board 1. The main board 1 is equipped with a locking mechanism 4 for locking the support mechanism 2 to always be in a supported state. The locking mechanism 4 includes a lifting component and an air supply component. The air supply component provides power to cooperate with the lifting component to lock the support mechanism 2 to always be in a supported state. The outer walls at both ends of the main board 1 are equipped with connection mechanisms 3 for connecting with other main boards 1.

[0019] It is important to note that by setting up support mechanism 2 in conjunction with locking mechanism 4, a continuous support effect is provided for the air duct template. The foldable support mechanism 2 makes it easy to install and disassemble, which is beneficial for installing and disassembling the whole device in confined spaces. At the same time, it can also reduce the space occupied by the whole device during transportation. Through the set connection mechanism 3, it can be connected to other main boards 1 to meet the support requirements of templates of different lengths and to be suitable for different support scenarios. Moreover, the support mechanism 2 on each main board 1 is an independent structure, which reflects the modular design and facilitates replacement and maintenance by subsequent maintenance personnel. When disassembling, the locking mechanism 4 is used to release the lock on the support mechanism 2, and then the support mechanism 2 is folded to remove the whole device.

[0020] like Figure 2 As shown, the support mechanism 2 includes a main block 201 installed at both ends of the top outer wall of the main board 1. A rotatable first rotating column 202 is installed in the main block 201. Side plates 203 are installed on both sides of the outer wall of the first rotating column 202. A support plate 205 is provided on the top outer wall of the main board 1. Second rotating columns 204 are installed on both ends of the outer wall of the support plate 205. The top of the side plate 203 is rotatably connected to the second rotating column 204.

[0021] It should be noted that the support plate 205 provides support for the air duct template. The first rotating column 202 and the second rotating column 204 allow both the side plate 203 and the support plate 205 to rotate, demonstrating the foldable effect of the support mechanism 2. A horizontal groove can be opened on one outer wall of the support plate 205, which makes the support plate 205 lighter. At the same time, reinforcing ribs can be added to the horizontal groove to ensure the strength of the support plate 205.

[0022] like Figures 2-4As shown, the lifting assembly includes a slot on the top outer wall of the main board 1 located at the bottom of the main block 201. An airbag 403 is installed in the slot. A top plate 405 is installed on the top outer wall of the airbag 403. A locking pin 406 is installed on the top outer wall of the top plate 405. A locking groove 407 corresponding to the locking pin 406 is opened on the bottom outer wall of the main block 201. The locking groove 407 extends through to the first rotating pin 202. The locking support mechanism 2 is locked in a supported state by the locking pin 406 being inserted into the locking groove 407 on the first rotating pin 202. A striking piece is embedded in the locking groove 407 on the first rotating pin 202.

[0023] It should be noted that by supplying air to the airbag 403 through the air supply component, the airbag 403 inflates, lifting the top plate 405 and the locking post 406, so that the locking post 406 is fully inserted into the locking groove 407. This prevents the first rotating post 202 from rotating, and consequently prevents the side plate 203 and the support plate 205 from rotating, thus locking the position of the support plate 205. That is, the support plate 205 provides a support effect. When the locking post 406 is fully inserted into the locking groove 407, the locking post 406 will collide with the striking piece, thus producing a sound, reminding the staff to complete the locking support state of the support mechanism 2. By extracting the gas from the airbag 403 through the air supply component, the airbag 403 will contract, causing the top plate 405 and the locking post 406 to move down, so that the locking post 406 will fall out of the locking groove 407, thus releasing the locking support state of the support mechanism 2, so as to fold the support mechanism 2.

[0024] like Figure 2 As shown, the air supply assembly includes a pump 401 mounted on the top outer wall of the main board 1, and an air pipe 402 connected to the pump 401 is installed between the two airbags 403 in the main board 1.

[0025] It should be noted that by activating the set pump 401, air can be supplied and depressed to the airbag 403 through the air pipe 402, thus completing the collision and contraction state of the airbag 403, and thereby locking and releasing the support state of the support mechanism 2. The battery that powers the pump 401 can be embedded in the motherboard 1.

[0026] like Figure 2 As shown, an air pressure sensor is installed inside the airbag 403, and air valves 404 are installed on the outer walls of both ends of the air tube 402.

[0027] It should be noted that the air pressure inside the airbag 403 can be monitored by the air pressure sensor. The air pressure when the support mechanism 2 is locked and when it is released is recorded. Then, the air valve 404 is used to control the air in and out, so that the pump 401 does not need to be in working state all the time, thereby extending the service life of the pump 401.

[0028] like Figure 2 As shown, the connecting mechanism 3 includes a plug 301 installed on the outer wall of the other end of the motherboard 1. A slot 304 corresponding to the plug 301 is provided on the outer wall of one end of the motherboard 1. Vertical grooves 303 are provided at both ends of the top inner wall of the slot 304 and the top outer wall of the plug 301. Limiting posts 302 are inserted into the vertical grooves 303.

[0029] It should be noted that when the air duct template requires two sets of support mechanisms 2 for support, the two motherboards 1 can be installed and connected together by inserting the plug 301 into the slot 304 and inserting the limiting post 302 into the vertical slot 303. Thus, the air duct template can be supported by two sets of support mechanisms 2. The installation and disassembly process is simple and quick, which is convenient for use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
