Description

Technical Field

[0001] This application relates to the field of building formwork technology, specifically an adjustable building formwork. Background Technology

[0002] In the field of building construction, the importance of formwork as a key tool for temporarily supporting concrete structures is self-evident. It plays a crucial role in maintaining the predetermined shape and position of the concrete during the pouring and hardening process.

[0003] The Chinese utility model patent with authorization announcement number CN209413286U discloses a flexible angle-adjustable building template. This template uses studs installed on the foundation or support, combined with U-shaped fixing grooves, to fix a second swing arm. The angle of the first swing arm is adjusted to adapt to the construction angle of the substrate. A square rotating block with its corners engages in a slot to limit the bottom of the first swing arm and determine the substrate angle. When the substrate construction angle is 90 degrees, a magnet is used to magnetically attract the sheet metal in the slot to ensure structural stability. However, this device relies on the square rotating block's corners engaging in the slot for fixing, which has inherent errors and cannot accurately ensure that the substrate angle is adjusted to the required construction position, thus affecting construction accuracy.

[0004] For example, the adjustable building formwork disclosed in Chinese utility model patent CN212613703U, through the design of a baffle, base plate, adjusting plate, limiting bolt, rotating shaft, slide groove two, slider two, and slide groove three, gives the building formwork a tilting angle function. When a fixed slope is required in special sites, the required angle can be formed by adjusting the limiting bolt and adjusting plate. At the same time, the design of slide groove one, slider one, reserved groove, and anti-slip pad reduces the dependence on external supports, reduces workload, improves work efficiency, and saves energy and is environmentally friendly. However, when adjusting the baffle angle, the baffle needs to be additionally installed on the base plate, and the angle of the baffle itself cannot be directly adjusted, which limits its flexibility of use.

[0005] Therefore, this application provides an adjustable building formwork to solve the above problems. Utility Model Content

[0006] This application provides an adjustable building formwork, which aims to solve the problems in the prior art where existing building formwork requires an outer plate as a base for angle adjustment.

[0007] To achieve the above objectives, this application provides the following technical solution: an adjustable building formwork, comprising a formwork body and an angle adjustment mechanism for adjusting the angle of the formwork body;

[0008] The template body consists of two hinged panels made of high-strength plastic or aluminum alloy. The hinged panel design provides the template body with an adjustable angle structure, allowing for flexible shape changes according to construction needs. The use of high-strength plastic or aluminum alloy for the panels offers advantages such as light weight, low cost, and corrosion resistance, while aluminum alloy boasts high strength, light weight, and good processing performance. This choice of materials ensures the template's strength, enabling it to withstand the pressure of concrete pouring, while also reducing its weight to some extent, facilitating handling and installation by construction personnel, and extending the template's service life.

[0009] The angle adjustment mechanism includes a threaded rod hinged to one of the panels, a threaded sleeve threaded onto the threaded rod, and a rotating rod rotatably connected to the end of the threaded sleeve away from the threaded rod. The rotating rod is hinged to the other panel. When the angle of one panel needs to be adjusted, the threaded sleeve is rotated. Due to the threaded engagement between the threaded sleeve and the threaded rod, the rotation of the threaded sleeve causes it to move axially along the threaded rod. Since the threaded sleeve is hinged to the other panel via the rotating rod, and the threaded rod is hinged to one panel, the movement of the threaded sleeve causes both panels to rotate around their hinge axis, thereby adjusting the panel angle. When the panel is adjusted to the desired angle, the rotation of the threaded sleeve is stopped, and the panel angle is then fixed.

[0010] Preferably, to facilitate the rotation of the threaded sleeve, a hexagonal plate is fixedly fitted onto the threaded sleeve. The hexagonal plate design provides multiple methods for driving the threaded sleeve's rotation. The threaded sleeve can be rotated manually by directly turning the hexagonal plate, which is simple and convenient. Alternatively, a wrench or other tools can be used to engage the hexagonal plate and drive the threaded sleeve to rotate. This method provides greater torque, is convenient for situations where manual rotation is difficult, and also allows for more precise control of the threaded sleeve's rotation angle, improving the accuracy of angle adjustment.

[0011] Preferably, to facilitate the protection of the threaded rod: a protective sleeve is slidably fitted onto the threaded sleeve, and the end of the protective sleeve away from the threaded sleeve is fixedly connected to the threaded rod. The protective sleeve effectively protects the threaded rod. In construction sites, the environment is complex, and the threaded rod is easily corroded by dust and other contaminants. The protective sleeve prevents these external factors from directly contacting the threaded rod, reducing rust and wear, thereby extending the service life of the threaded rod and the entire angle adjustment mechanism, ensuring the angle adjustment mechanism always functions normally, and improving the reliability of the formwork.

[0012] Preferably, to facilitate the interconnection between the template bodies: a connecting frame is fixedly connected to one side of the panel near the angle adjustment mechanism, and the connecting frame has through holes for bolt insertion. The design of the connecting frame and the through holes facilitates the interconnection between the template bodies. In construction, it is often necessary to splice multiple templates together. By fastening the connecting frames of different templates through the through holes with bolts, multiple templates can be formed into a whole, meeting the needs of large-area construction, improving construction efficiency, and ensuring the stability of the spliced ​​template structure, which can better withstand the pressure during concrete pouring.

[0013] Preferably, to improve the stability of the template body: fixed sleeves are hinged to both sides of one of the panels corresponding to the angle adjustment mechanism, and guide rods, hinged to the other panel, are slidably inserted into the fixed sleeves. The fixed sleeves and guide rods improve the stability of the template body. During panel angle adjustment and concrete pouring, this structure assists the angle adjustment mechanism in sharing some of the force, preventing excessive deformation or shaking of the panels under stress, ensuring the template body remains stable under different working conditions, thereby improving concrete pouring quality and reducing construction defects caused by template instability.

[0014] This application utilizes a design with two hinged panels, providing the formwork body with an adjustable angle structure, allowing for flexible shape changes according to construction needs. The angle adjustment mechanism precisely adjusts one of the two panels located on the same plane to an inclined position as required. While ensuring the formwork body retains its original planar formwork functionality, this significantly expands the formwork's applicability and improves its practicality. This adjustment mechanism is simple in structure, easy to operate, and low in cost, making it suitable for various construction scenarios.

[0015] This application effectively protects the threaded rod by using a protective sleeve. In construction sites, the environment is complex, and the threaded rod is susceptible to corrosion from dust and other contaminants. The protective sleeve prevents these external factors from directly contacting the threaded rod, reducing rust and wear, thereby extending the service life of the threaded rod and the entire angle adjustment mechanism. This ensures the angle adjustment mechanism always functions properly and improves the reliability of the formwork.

[0016] This application improves the stability of the formwork body by setting up a fixed sleeve and guide rod. During the adjustment of the panel angle and the concrete pouring process, this structure can assist the angle adjustment mechanism in sharing part of the force, preventing excessive deformation or shaking of the panel under stress, and ensuring that the formwork body remains stable under different working conditions, thereby improving the quality of concrete pouring and reducing construction defects caused by formwork instability.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] This embodiment provides an adjustable building formwork, such as Figure 1-3 As shown, the building template includes a template body 1 and an angle adjustment mechanism 2 for adjusting the angle of the template body 1.

[0024] The formwork body 1 consists of two hinged panels 11, made of high-strength plastic or aluminum alloy. The hinged design provides the formwork body 1 with an adjustable angle structure, allowing for flexible shape changes according to construction needs. The panels 11 are made of either high-strength plastic, which is lightweight, low-cost, and corrosion-resistant, while aluminum alloy offers high strength, light weight, and good processing performance. This choice of materials ensures the formwork's strength, enabling it to withstand the pressure of concrete pouring, while also reducing its weight for easier handling and installation by construction personnel, thus extending its service life. The two panels 11 are connected by a hinged structure, allowing relative rotation and thus changing the overall shape of the formwork body 1 to adapt to the angle requirements of different construction scenarios. During construction, the panels 11, thanks to their material properties, withstand the lateral pressure of the concrete and other external forces, ensuring the smooth progress of concrete pouring.

[0025] The angle adjustment mechanism 2 includes a threaded rod 21 hinged to one of the panels 11, a threaded sleeve 22 threaded onto the threaded rod 21, and a rotating rod 23 rotatably connected to the end of the threaded sleeve 22 away from the threaded rod 21. The rotating rod 23 is hinged to the other panel 11. The angle adjustment mechanism 2 allows for precise adjustment of one of the two panels 11 located in the same plane to an inclined state according to usage requirements. While ensuring that the template body 1 does not lose its original planar template function, it greatly expands the applicability of the template and improves its suitability. This adjustment mechanism has a simple structure, is easy to operate, and has low cost, making it suitable for various construction scenarios. When it is necessary to adjust the angle of one of the panels 11, the threaded sleeve 22 is rotated. Due to the threaded engagement between the threaded sleeve 22 and the threaded rod 21, the rotation of the threaded sleeve 22 causes it to move axially along the threaded rod 21. Since the threaded sleeve 22 is hinged to another panel 11 via the rotating rod 23, and the threaded rod 21 is hinged to one panel 11, when the threaded sleeve 22 moves, it will cause the two panels 11 to rotate around the hinge axis between them, thereby adjusting the angle of the panels 11. When the panel 11 is adjusted to the required angle, the rotation of the threaded sleeve 22 is stopped, and the angle of the panel 11 is fixed.

[0026] To facilitate the rotation of the threaded sleeve 22, a hexagonal plate 221 is fixedly mounted on the threaded sleeve 22. The design of the hexagonal plate 221 provides multiple methods for driving the rotation of the threaded sleeve 22. The threaded sleeve 22 can be rotated manually by directly rotating the hexagonal plate 221, which is simple and convenient. Alternatively, a wrench or other tool can be used to engage the hexagonal plate 221, which provides greater torque and is convenient for situations where manual rotation is difficult. It also allows for more precise control of the rotation angle of the threaded sleeve 22, improving the accuracy of angle adjustment. Whether manually or with a wrench, force is applied to the hexagonal plate 221. Because the hexagonal plate 221 is fixedly mounted on the threaded sleeve 22, the force applied to the hexagonal plate 221 is transmitted to the threaded sleeve 22, causing it to rotate around its axis, thereby driving the angle adjustment mechanism 2 of the panel 11.

[0027] To facilitate the protection of the threaded rod 21, a protective sleeve 211 is slidably fitted onto the threaded sleeve 22, with the end of the protective sleeve 211 away from the threaded sleeve 22 fixedly connected to the threaded rod 21. The protective sleeve 211 effectively protects the threaded rod 21. In construction sites, the environment is complex, and the threaded rod 21 is easily corroded by dust and other contaminants. The protective sleeve 211 prevents these external factors from directly contacting the threaded rod 21, reducing rust and wear, thereby extending the service life of the threaded rod 21 and the entire angle adjustment mechanism 2, ensuring the angle adjustment mechanism 2 always functions normally, and improving the reliability of the formwork. When the threaded sleeve 22 moves along the threaded rod 21 for angle adjustment, the protective sleeve 211 slides along the threaded sleeve 22. Since one end of the protective sleeve 211 is fixedly connected to the threaded rod 21, the protective sleeve 211 always surrounds the threaded rod 21, providing a protective barrier and blocking external dust and other contaminants from damaging the threaded rod 21.

[0028] To facilitate the interconnection between template bodies 1, a connecting frame 12 is fixedly connected to one side of the panel 11 near the angle adjustment mechanism 2. The connecting frame 12 has through holes 121 for bolt insertion. The design of the connecting frame 12 and the through holes 121 facilitates the interconnection between template bodies 1. In construction, multiple templates are often spliced ​​together. By fastening the connecting frames 12 of different templates through the through holes 121 with bolts, multiple templates can form a whole, meeting the needs of large-area construction, improving construction efficiency, and ensuring the stability of the spliced ​​template structure, better able to withstand the pressure of concrete pouring. When splicing templates, align the connecting frame 12 of one template with the corresponding connecting frame 12 of another template, then insert bolts into the corresponding through holes 121 on the two connecting frames 12, and then tighten the bolts with nuts. The tightening force of the bolts tightly connects the two connecting frames 12 together, thus achieving a reliable connection between template bodies 1.

[0029] To improve the stability of the template body 1, fixed sleeves 3 are hinged to both sides of the angle adjustment mechanism 2 on one of the panels 11. A guide rod 31, hinged to the other panel 11, is slidably inserted into the fixed sleeve 3. The fixed sleeves 3 and guide rod 31 enhance the stability of the template body 1. During the adjustment of the panel 11 angle and concrete pouring, this structure assists the angle adjustment mechanism 2 in sharing some of the force, preventing excessive deformation or shaking of the panel 11 under stress. This ensures the template body 1 remains stable under different working conditions, thereby improving the quality of concrete pouring and reducing construction defects caused by template instability. When the angle of the panel 11 changes, the guide rod 31 slides within the fixed sleeve 3, and the hinge points between the guide rod 31 and the two panels 11 move with the rotation of the panels 11. During concrete pouring and other processes, the formwork body 1 is subjected to external forces such as lateral pressure from the concrete. At this time, the structure formed by the fixed sleeve 3 and the guide rod 31 will disperse and transmit these external forces. Through the sliding of the guide rod 31 in the fixed sleeve 3 and their hinge relationship with the panel 11, the position and stress state of the formwork body 1 are adjusted to maintain the stability of the formwork body 1 and ensure the reliability of the formwork during the working process.

The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0031] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
