Description

Technical Field

[0001] This invention relates to the field of formwork construction technology, specifically to a formwork support construction device suitable for confined spaces. Background Technology

[0002] The quality of the cast-in-place reinforced concrete structure of the integrated utility tunnel is directly related to the formwork engineering. At present, the formwork engineering mostly uses wooden formwork, square timber backing and steel pipe support. The formwork construction usually follows the construction sequence of the bottom slab first, then the side walls and the top slab. The bottom slab is installed according to the layout position. The outside is supported by steel frame pipes or wooden supports to the foundation pit slope or support piles. According to the formwork drawing, the formwork panels, vertical joists and horizontal joists are assembled into a whole. The assembled formwork is hoisted or manually positioned. The formwork on both sides is tied and fixed by tie bolts. The back is supported by a steel pipe scaffolding support system for diagonal bracing and top bracing to ensure overall stability. In traditional construction of pipe galleries, basements, or irregular structures, large machinery cannot enter the site when encountering confined spaces, and workers' operating space is limited. This makes the installation, adjustment, and dismantling of traditional modular formwork and support systems, such as steel pipes and square timber, extremely difficult. This increases construction costs and delays the project schedule. Furthermore, in confined spaces, it is common to encounter situations where the side walls are inclined. Conventional formwork support devices can mostly only handle vertical side walls, which reduces the support effect for inclined side walls. Summary of the Invention

[0003] The purpose of this invention is to provide a formwork support construction device suitable for confined spaces. An elastic component allows the side plates to rotate on the surface of a vertical plate, enabling the vertical plate to press the side plates against the inclined pipe gallery formwork surface and ensure the side plates are fully fitted to the formwork surface. Simultaneously, a distance adjustment component allows for adjustment of the distance between the two side plates in the horizontal direction, ensuring the side plates are tightly pressed against the formwork surface, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A formwork support construction device suitable for confined spaces is used to support inclined formwork. It includes four side plates, four connectors, and four distance adjustment components. The connectors include horizontal plates, vertical plates, and hinge plates. The horizontal plates and vertical plates are perpendicular to each other and fixedly connected. The hinge plates are located at one end of the vertical plates. The four side plates are respectively located on the four horizontal plates. One side of each of the four side plates abuts against the formwork. Adjacent hinge plates and adjacent horizontal plates are fixedly connected by distance adjustment components.

[0005] Preferably, the side plate is provided with an elastic component, and the side plate is rotatably connected to the vertical plate through the elastic component. The tilt angle of the side plate is the same as the tilt angle of the template.

[0006] Preferably, the elastic component includes ear seats, connecting seats, rotating shafts, and elastic elements. Two ear seats are fixedly mounted on a vertical plate, the rotating shaft is fixedly mounted on the connecting seats, the connecting seats are fixedly mounted on a side plate, the rotating shaft is rotatably connected between the two ear seats, and the elastic element is installed between the rotating shaft and the ear seats.

[0007] Preferably, the elastic element is a torsion spring, which is sleeved on the rotating shaft, and both ends of the torsion spring are fixedly connected to the connecting seat and the ear seat, respectively.

[0008] Preferably, the distance adjustment assembly includes a base plate, a main shaft, and two traction rods. The main shaft is rotatably connected to the base plate, and the two traction rods are slidably connected inside the base plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention uses an elastic component to allow the side plate to rotate on the surface of the vertical plate, so that the vertical plate can press the side plate against the inclined tube gallery template surface and ensure that the side plate is fully attached to the template surface.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] One preferred embodiment of this application, such as Figures 1 to 7 As shown: A formwork support construction device suitable for confined spaces is used to support inclined formwork. It includes four side plates 1, four connectors 2, and four distance adjustment components 3. The connectors 2 include horizontal plates 21, vertical plates 22, and hinge plates 23. The horizontal plates 21 and vertical plates 22 are perpendicular to each other and fixedly connected. The hinge plates 23 are located at one end of the vertical plates 22. The four side plates 1 are respectively located on the four horizontal plates 21. One side of the four side plates 1 abuts against the formwork. The two adjacent hinge plates 23 and the two adjacent horizontal plates 21 are fixedly connected by the distance adjustment components 3.

[0019] An elastic component 4 is provided on the side plate 1. The side plate 1 is rotatably connected to the vertical plate 22 through the elastic component 4. The tilt angle of the side plate 1 is the same as the tilt angle of the template.

[0020] Please see Figures 1 to 3 The device uses four connectors 2 as nodes and four side plates 1 as supporting legs to form a three-dimensional frame. The size of this three-dimensional frame is then changed synchronously by the distance adjustment component 3, allowing it to be transported into a confined space and expanded to tightly press against the template from four directions, forming a stable internal support structure. The L-shaped structure of the horizontal plate 21 and the vertical plate 22 ensures that the structure has sufficient bending stiffness. The side plate 1 is equipped with an elastic component 4, which allows it to rotate relative to the vertical plate 22 and provides rotational force to the side plate 1, ensuring that the side plate 1 can automatically press against the inclined template surface at the same angle as the template. In a confined space, the worker only needs to place the entire device in and then operate the distance adjustment component 3 to quickly support the inclined template, greatly improving work efficiency and ensuring the integrity and reliability of the support system.

[0021] The elastic component 4 includes ear seats 41, connecting seats 42, rotating shafts 43 and elastic elements. Two ear seats 41 are fixedly installed on the vertical plate 22, the rotating shaft 43 is fixedly installed on the connecting seats 42, the connecting seats 42 are fixedly installed on the side plate 1, the rotating shaft 43 is rotatably connected between the two ear seats 41, and the elastic element is installed between the rotating shaft 43 and the ear seats 41. The elastic element is a torsion spring 44, which is sleeved on the rotating shaft 43, and both ends of the torsion spring 44 are fixedly connected to the connecting seats 42 and the ear seats 41 respectively.

[0022] Please see Figure 4 When supporting the inclined template, workers do not need to accurately calculate the angle of the side plate 1 and perform tedious fixing. They only need to open the entire frame through the distance adjustment component 3. When the side plate 1 contacts the inclined template surface, under the action of the contact reaction force, the side plate 1 will automatically rotate around the pivot 43 until its entire side plate 1 plane is completely in contact with the template surface. The continuous torque provided by the torsion spring 44 is equivalent to an automatic clamp, forcing the side plate 1 to always be in close contact with the template surface no matter what angle it rotates to.

[0023] Specifically, the elastic component 4 allows the side plate 1 to rotate on the surface of the vertical plate 22, so that the vertical plate 22 can press the side plate 1 against the inclined tube gallery template surface and make the side plate 1 fully fit the template surface. At the same time, the distance adjustment component 3 allows the distance between the two side plates 1 in the horizontal direction to be adjusted, so that the side plate 1 can be pressed tightly against the template surface, thereby achieving horizontal support for the template 1. Meanwhile, the other two distance adjustment components 3 can adjust the distance between the two side plates 1 in the vertical direction, so that the whole device can adapt to tube galleries of different sizes.

[0024] It should be noted that the side plate 1 can be designed as a quick-replaceable module, for example, it can be replaced with a side plate 1 with an arc surface to support a circular silo, or it can be replaced with a side plate 1 with a sealing edge for fair-faced concrete construction. Multiple such devices can be connected to each other at the top and bottom through additional connectors 2 to form a huge, uniform support wall for the construction of large-area inclined walls, ensuring that the support rigidity and accuracy of the entire wall are consistent.

[0025] The distance adjustment assembly 3 includes a base plate 31, a main shaft 32, and two traction rods 33. The main shaft 32 is rotatably connected to the base plate 31, and the two traction rods 33 are slidably connected inside the base plate 31. One end of each traction rod 33 is fixedly connected to a horizontal plate 21 and a hinge plate 23, respectively. The two traction rods 33 are centrally symmetrical about the main shaft 32. A traction structure is connected between the two traction rods 33 and the main shaft 32. The traction structure includes a gear 34 and a toothed part 37. The two toothed parts 37 are fixedly connected to the two traction rods 33, respectively. The gear 34 is coaxially fixedly installed on the main shaft 32 and simultaneously meshes with the two toothed parts 37. A strip-shaped protrusion 6 is fixedly installed inside the base plate 31. A limiting groove 5 is provided on the traction rod 33, and the traction rod 33 is slidably connected to the strip-shaped protrusion 6 through the limiting groove 5.

[0026] Please see Figures 5 to 7 When the main shaft 32 is rotated, the two traction rods 33 can be driven to make equidistant and opposite linear movements within the base plate 31 through the transmission of the gear 34 and the toothed part 37, thereby synchronously adjusting the distance between the two adjacent side plates 1. The two traction rods 33 with toothed parts 37 are driven simultaneously by a common gear 34, ensuring that the extension and retraction of the two side plates 1 are completely synchronous and symmetrical during the adjustment process. The cooperation between the strip-shaped protrusion 6 and the limiting slide groove 5 ensures that the traction rods 33 can only slide in a straight line, eliminating the possibility of shaking or jamming, making the adjustment process smooth and precise, and enabling the gear 34 and the toothed part 37 to mesh precisely.

[0027] A driving structure is provided on the substrate 31. The driving structure includes a worm 35 and a worm wheel 36. The worm wheel 36 is coaxially fixedly mounted on the main shaft 32. The worm 35 is rotatably connected to the substrate 31 and meshes with the worm wheel 36. A protective shell 7 is fixedly mounted on the substrate 31. The top end of the main shaft 32 is rotatably connected to the inner wall of the protective shell 7. The worm wheel 36 is located between the main shaft 32 and the protective shell 7. The worm 35 is rotatably connected to the protective shell 7.

[0028] Please see Figure 5 The mechanism formed by the worm gear 36 and the worm 35 has a unidirectional transmission characteristic, that is, the worm 35 can drive the worm gear 36, but the huge reverse torque from the worm gear 36, such as the lateral pressure of the concrete, cannot drive the worm 35 to reverse. This provides mechanical self-locking for the entire support frame, preventing the support frame from loosening and shrinking due to pressure during the pouring process. The protective shell 7 can prevent cement mortar and other debris from entering the precision transmission pair, causing jamming or wear, and can also prevent the operator's hands or clothing from being caught. At the same time, it can also provide additional support for the worm 35 and the main shaft 32, enhancing the structural rigidity.

[0029] The distance adjustment assembly 3 also includes a limiting rod 38 and a cavity 39. The cavity 39 is opened inside the base plate 31. One end of the limiting rod 38 is fixedly connected to the horizontal plate 21 and the hinge plate 23 respectively, and the other end of the limiting rod 38 is axially slidably connected in the cavity 39.

[0030] Please see Figure 6 The limiting rod 38 itself has tensile, compressive and bending resistance capabilities. It shares the force with the traction rod 33, which significantly improves the overall rigidity and load-bearing capacity of the distance adjustment component 3. Furthermore, the sliding of the limiting rod 38 in the cavity 39 is strictly limited to the axial direction, which effectively prevents the connector 2 from deflecting in the horizontal plane and ensures that the side plate 1 is always facing the template. The limiting rod 38 and the cavity 39 constitute an auxiliary guiding and anti-torsion mechanism, which is specifically responsible for resisting the torque that may cause the frame to twist or rotate, and ensuring that the entire support frame maintains geometric stability when subjected to complex loads.

[0031] It should be noted that a high-polymer wear-resistant bushing can be embedded inside the cavity 39, which can reduce friction and noise, avoid direct contact between metals, and prevent jamming due to corrosion. At the same time, the end of the limiting rod 38 can be designed as a ball joint to release the minor assembly stress that may exist during installation.
