Description

Technical Field

[0001] This application relates to the field of early formwork removal technology, and in particular to a dismantling head structure for an early formwork removal system. Background Technology

[0002] Wooden formwork is a temporary support system used for concrete molding in building construction. It consists of wooden panels, beams, and a supporting frame. Its function is to bear the load of newly poured concrete and provide a certain degree of fixation. Early formwork removal technology utilizes the early strength of concrete (when it reaches 50%-70% of the design strength) to remove non-load-bearing formwork and auxiliary supports in advance, while retaining key load-bearing nodes to maintain structural stability, thereby achieving efficient formwork turnover and optimized construction period.

[0003] In the prior art, the early dismantling head (hereinafter referred to as "dismantling head") is the core support component after the partial template is dismantled. During the dismantling of the partial template, the crossbeams erected on the dismantling head structure need to be dismantled simultaneously. However, a crossbeam is erected on at least two dismantling heads. During the operation, the crossbeam may lose balance and overturn, causing a safety accident. Therefore, this application proposes a new technical solution. Utility Model Content

[0004] To improve safety when dismantling crossbeams, this application provides a dismantling head structure for an early dismantling system for wooden formwork.

[0005] This application provides a dismantling head structure for an early stripping system of timber formwork, employing the following technical solution:

[0006] A dismantling head structure for an early dismantling system of wooden formwork includes an early dismantling head and a vertical pole fixed and supporting the early dismantling head. The early dismantling head includes a top plate for supporting the top formwork and a support plate for mounting a crossbeam. The top plate is fixed to the end of the vertical pole. The support plate is located below the top plate and is penetrated by the vertical pole and slidably connected to the vertical pole. The two ends of the support plate are bent upward to form two wing plates. The crossbeam is located between the vertical pole and the wing plates. The vertical pole is provided with a fixing component for fixing the support plate.

[0007] It also includes a lowering mechanism for assisting the pallet to descend. The upright is connected to a fixed base at a position below the pallet. The lowering mechanism is located between the fixed base and the pallet, and the bottom of the lowering mechanism is supported by the fixed base. The lowering part of the lowering mechanism is connected to the pallet.

[0008] Optionally, the structure includes multiple telescopic tubes nested together to form a telescopic structure. The telescopic tubes are sleeved on the outside of the upright. The outermost telescopic tube is connected to the support plate, and the innermost telescopic tube is connected to the fixed base. Both ends of the telescopic tube are sealed, and its inner wall forms a water storage cavity between the upper and lower ends and the outer wall of the upright. The top of the next telescopic tube is located in the water storage cavity of the previous telescopic tube, and its end has a water channel that allows adjacent water storage cavities to communicate with each other. The outermost telescopic tube is provided with a pipe joint for water inlet, and the innermost telescopic tube with a water storage cavity is provided with a pipe joint for water outlet and a valve installed on the pipe joint.

[0009] Optionally, the early removal head is provided with a limiting mechanism, which includes a limiting rod that penetrates the crossbeam and the support plate. The limiting rod and the support plate are threaded together, and the limiting rod slides through the crossbeam.

[0010] Optionally, the fixing component includes a coaxial pin hole formed in the upright and the support plate, and a pin that is inserted into the pin hole after being pulled up to a preset height.

[0011] Optionally, the upright has multiple pin holes along its axial direction, and the end of the pin has a binding hole with a hanging rope passing through and fixed in the binding hole. The other end of the hanging rope is connected to the support plate.

[0012] Optionally, the non-bent lateral portion of the pallet is called the horizontal plate. The wing plate is rotatably connected to the horizontal plate. The wing plate is arc-shaped when viewed from above, and its open end abuts against the crossbeam. The wing plate is connected to a spring, and one end of the spring is connected to the end of the horizontal plate. When the spring is in its natural state, the angle between the wing plate and the horizontal plate is at its minimum value. An elastic pad is provided on the side wall of the wing plate that abuts against the crossbeam.

[0013] In summary, this application includes the following beneficial technical effects: the pallet and the upright are slidably fitted together, and the pallet is connected to the lowering mechanism. The lowering mechanism can drive the pallet to rise and fall. When the pallet is lowered, the crossbeam can be removed more easily and conveniently. The pallet supports the crossbeam, reducing the risk of the crossbeam tilting and slipping, and improving the safety when disassembling the crossbeam. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a head-removal structure for an early stripping system of wooden formwork.

[0020] Reference Figure 1 The early stripping system for wooden formwork uses a stripping head structure, which includes an early stripping head 1, a vertical pole 2 that is fixed and supports the early stripping head 1, and a lowering mechanism 3 that lowers an auxiliary support plate 12. The vertical pole 2 and the early stripping head 1 can continue to support the concrete structure after part of the formwork is removed. The early stripping head 1 includes a top plate 11 and a support plate 12. The top plate 11 can be welded to the top of the vertical pole 2. The support plate 12 is slidably fitted and connected to the vertical pole 2. Both ends of the support plate 12 are bent upwards and form two symmetrical wing plates 121. There can be two crossbeams 7, which are snapped between the vertical pole 2 and the two wing plates 121.

[0021] Reference Figure 1 and Figure 2 A fixed seat 4 is welded to the upright 2 below the support plate 12. The fixed seat 4 can be ring-shaped and sleeved on the upright 2. The lowering mechanism 3 is located between the fixed seat 4 and the support plate 12, and the two ends of the lowering part of the lowering mechanism 3 are connected to the fixed seat 4 and the support plate 12 respectively, so as to facilitate the lifting and lowering of the support plate 12.

[0022] According to the above configuration, by fixing the pallet 12 and the lowering mechanism 3, the lowering mechanism 3 can realize the lifting and lowering of the pallet 12. When the pallet 12 is lowered, the crossbeam 7 can be taken out more easily and conveniently. Moreover, the pallet 12 supports the crossbeam 7, which reduces the risk of the crossbeam 7 tilting and slipping, and improves the safety when disassembling the crossbeam 7.

[0023] Reference Figure 2 The lowering mechanism 3 includes a sealed telescopic tube 31 (i.e., the lifting part mentioned above) for filling with water. The two ends of the telescopic tube 31 can be connected to the fixed seat 4 and the support plate 12 respectively by welding or snap-fitting. For example, snap-fitting blocks are provided at both ends of the telescopic tube 31, and snap-fitting grooves corresponding to the snap-fitting blocks are provided on the fixed seat 4 and the support plate 12 respectively. Snap-fitting is completed by inserting the snap-fitting blocks into the snap-fitting grooves. The snap-fitting method makes it easier to disassemble or replace the telescopic tube 31.

[0024] The telescopic tube 31 is a multi-sleeve structure, with at least two sections (the following explanation uses a three-sleeve configuration). It can be sleeved onto the upright 2 (the sleeve and upright 2 can be cylindrical or rectangular in plan view; the following explanation uses a rectangle). When the telescopic tube 31 is extended, the outermost sleeve section (the topmost section) has the largest length and width. The length and width of the remaining sleeve sections decrease sequentially from top to bottom. The ends of every two adjacent sleeve sections interlock and abut against each other. Both ends of the telescopic tube 31 are sealed, and its inner wall forms a water-retaining cavity between the inner wall and the outer wall of the upright 2. Sealing units, such as rubber rings, are provided at the abutting ends of the sleeves to form a seal. Example: The top of the uppermost sleeve section is fixed to the support plate 12, and both ends face... Folding inwards to form an inward buckle, the top edge of the adjacent sleeve section then folds outwards, abutting against the inner wall of the first (topmost) sleeve section. A rubber ring is bonded to the abutting side wall. Simultaneously, the lower end of this second sleeve section buckles inwards. The remaining sleeves follow the pattern of the second sleeve section, decreasing in size from top to bottom until the bottom of the last sleeve section is sealed and fixed to the fixing base 4. This multi-section combination achieves a telescopic and sealing effect. The bottommost sleeve section can be solid, while the remaining sleeves are hollow inside to allow water filling. Their ends abut against the upright 2, and water channels are excavated in the middle to connect adjacent water storage chambers, allowing water to flow downwards.

[0025] The top section of the telescopic pipe 31 (i.e., the first section of the sleeve) is equipped with a pipe fitting 32 for water inlet. This pipe fitting 32 is connected to a water supply pipe and has a threaded cap when not in use. The second section of the sleeve is equipped with a pipe fitting 32 for water outlet, and a valve is installed on the pipe fitting 32. In order not to obstruct the operation of the pipe fitting for drainage, the pipe fitting is exposed when the top of the second section of the sleeve abuts against the top of the first section of the sleeve.

[0026] With the above setup, water can be input from the top pipe joint 32 and gradually fill the inner cavity of the telescopic pipe 31, causing the telescopic pipe 31 to extend. After the water supply stops, the pipe joint 32 is sealed, and the interior is supported by water. Even if the crossbeam 7 presses down, the telescopic pipe 31 can maintain its height, providing a certain degree of support for the top crossbeam 7 and the formwork. When it is necessary to disassemble the crossbeam 7, the valve can be opened, and the water outlet pipe joint 32 at the bottom begins to drain water outwards. The telescopic pipe 31, along with the crossbeam 7, gradually descends, achieving the effect of reducing the height of the crossbeam 7.

[0027] In another embodiment of this application:

[0028] Since the crossbeam 7 is supported on at least two uprights 2 and a support plate 12, two ports of the multi-port water pipe can be connected to the outlet and inlet pipe joints 32 of the telescopic pipes 31 on two adjacent uprights 2, respectively. This allows for simultaneous control of water inlet and outlet, further enabling more synchronized descent of the crossbeam 7 and reducing the risk of it tipping over. Furthermore, the main pipe of the multi-port water pipe can be connected to a water tank, which in turn connects to a water supply pipe and a water pump. The water pump, through the water supply pipe, connects to the pipe joints of each telescopic pipe, thus enabling water recycling.

[0029] Reference Figure 1 and Figure 3 The early disassembly head 1 is equipped with a limiting mechanism 5 for fixing the support plate 12 and the top plate 11. The limiting mechanism 5 includes a limiting rod 51 that penetrates the crossbeam 7 and the support plate 12. The support plate 12 has a threaded hole along its thickness direction that is threaded to the limiting rod 51. The crossbeam 7 has a limiting hole along its width direction for penetration. The limiting rod 51 achieves the effect of fixing the crossbeam 7 by cooperating with the limiting hole of the crossbeam 7 and the threaded hole of the support plate 12. The end of the limiting rod 51 is fitted with a locking nut, thereby fixing the crossbeam 7 and the limiting rod 51, which can effectively reduce the loosening between the crossbeam 7 and the support plate 12 and thus reduce displacement.

[0030] Reference Figure 1 and Figure 3 The upright 2 is equipped with a fixing component for lifting and locking the height position of the telescopic tube 31, thereby allowing water to be poured into the telescopic tube 31. The fixing component includes a pin hole and a pin 6 that are coaxially opened on the upright 2 and the support plate 12. The positions of the pin holes on the upright 2 and the support plate 12 need to overlap when the support plate 12 is lifted to a certain height, so that the pin 6 can be inserted into the pin hole after being lifted to the preset height to lock the fixing component.

[0031] With the above settings, even when the lowering mechanism 3 is not filled with water and cannot support the upper support plate 12 and the crossbeam 7, the telescopic tube 31 can be manually pulled up to a certain height, such as 2 / 3 of the upright 2.

[0032] The telescopic tube 31 can be easily fixed by the pin 6 and the pin hole. Water can be poured into the telescopic tube 31. When the water in the lowering mechanism 3 is gradually filled, the tray 12 can be supported upward by the telescopic tube 31. At the same time, the pin is fixed. The two work together to further ensure that the tray 12 is fixed at the specified height.

[0033] The upright 2 has multiple pin holes along its axial direction, which can be used to temporarily fix the telescopic tube 31 to a specified height as needed. The pin 6 has a binding hole at its end, and a hanging rope is inserted and fixed in the binding hole. The other end of the hanging rope is connected to the support plate 12, so the pin 6 can be directly tied to the support plate 12. This eliminates the need to find or take out the pin 6 during work. The suspended pin 6 can be directly inserted, which is more convenient. Moreover, the length of the hanging rope can be adjusted according to specific needs.

[0034] Reference Figure 1 and Figure 3 The non-bent lateral portion of the support plate 12 is called the horizontal plate 123. The wing plate 121 is rotatably connected to the horizontal plate 123, and the two can be hinged. The wing plate 121 is arc-shaped when viewed from above, and its open end abuts against the crossbeam 7. That is, the wing plate 121 is an arc plate with a large curvature. Both ends are bent towards the crossbeam 7, and the wing plate 121 is set vertically. When viewed from above, it is arc-shaped, or it can be C-shaped. When viewed from the side, it is similar to a semicircle. The wing plate 121 is connected to a spring 122, and one end of the spring 122 is connected to the end of the horizontal plate 123. One end of the spring 122 is connected to the concave surface of the wing plate 121, which can be at the height of the middle of the wing plate 121. The other end of the spring 122 is connected to the end of the horizontal plate 123. The two ends can be connected by welding or by hooks. That is, the wing plate 121 and the horizontal plate 123 each have small rings, and the two ends of the spring 122 have round hooks. The round hooks have a locking function. After hooking, they lock to prevent loosening during rotation. When the spring 122 is in its natural state, the angle between the wing plate 121 and the cross plate 123 is at its minimum value, such as 60 degrees. Therefore, when the cross beam 7 is inserted into the support plate 12, the tension of the spring 122 can further lock the cross beam 7. An elastic pad is provided on the side wall of the wing plate 121 that abuts against the cross beam 7. The elastic pad can be made of rubber to reduce the wear and tear caused by the collision between the two.

[0035] Implementation principle:

[0036] When disassembling the crossbeam 7, remove the pin 6 to release the lock on the crossbeam 7, open the valve of the pipe joint 32 at the bottom of the telescopic pipe 31 for water outlet, drain water through the multi-port water pipe, and achieve water recycling through the external water tank, water pump and water supply pipe. During the drainage process, the telescopic pipe 31 gradually reduces its length, driving the support plate 12 and the crossbeam 7 on the support plate 12 to descend. Loosen the locking nut and rotate the limit rod 51 to release the fixation between the support plate 12 and the crossbeam 7. Pry the wing plate 121 outward to remove the crossbeam 7.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
