Description

Technical Field

[0001] This utility model relates to the field of building engineering, specifically to a building formwork support device. Background Technology

[0002] Formwork support systems are crucial facilities for ensuring the quality of concrete structure forming and construction safety. Their main function is to provide stable support for the formwork during the pouring process, ensuring that the concrete maintains its designed shape and dimensions before solidification. With the continuous development of the modern construction industry, building structures are becoming increasingly complex and diverse. Curved floor slabs, irregular beams, and large-span spatial structures are widely used in various types of buildings, which places higher demands on the adaptability, stability, and adjustment precision of formwork support systems.

[0003] Currently, traditional formwork support devices mostly adopt a combination structure of horizontal and vertical bars with a fixed module. The spacing between adjacent support units is fixed by the length of the horizontal bars, making it difficult to flexibly adjust according to the dimensional requirements of complex building structures. When dealing with curved or irregularly shaped structures, it is often necessary to cut the horizontal bars or add additional connectors, which not only increases construction costs and time but may also affect the overall stability of the support system due to insufficient connection strength. Summary of the Invention

[0004] The purpose of this utility model is to provide a building formwork support device, which includes multiple support units. The spacing between adjacent support units is adjustable through a first adjustment component, which solves the limitation of traditional fixed modular crossbars on the adaptation of complex building structures. At the same time, combined with the height adjustment structure formed by the second adjustment component, it forms an all-round adjustment capability in the spatial dimension, which greatly improves the adaptation range of complex building formwork.

[0005] This utility model is achieved through the following technical solution: A building formwork support device includes support units, wherein multiple support units are provided, and adjacent support units are connected by a first adjustment component, wherein the first adjustment component makes the spacing between adjacent support units adjustable; The support unit includes a top support for supporting the building formwork and a support body. The support body and the top support are connected by a second adjustment component, so that the top support can move longitudinally.

[0006] In this solution, by setting up multiple support units and using the first adjustment component to make the spacing between adjacent support units adjustable, the problem of adapting to complex building structures such as arcs and irregular shapes is solved, enabling the device to flexibly adjust the support range according to the size requirements of different building structures. At the same time, the top support and the support body in the support unit can move longitudinally through the second adjustment component. Combined with the horizontal spacing adjustment function of the first adjustment component, the device has a comprehensive adjustment capability in the spatial dimension, which greatly improves the adaptability range to complex building templates and ensures that the support device can accurately fit building templates of different heights and shapes.

[0007] A further technical solution for the support device is that the top support is provided with a U-shaped groove that matches the building template, which increases the contact area between the top support and the template, so that the load can be transferred to the support unit more evenly and avoid excessive local stress that could damage the template or the top support.

[0008] A further technical solution to the support device is that the second adjustment component includes a vertical rod, a screw, and an adjustment block; One end of the screw is connected to the top support, and the other end of the screw is threadedly connected to the upright through the adjusting block. When the adjusting block is rotated, the screw moves along the axis of the upright. This, combined with the adjustable horizontal spacing function of the first adjusting component, forms an all-round adjustment capability of the support device in the spatial dimension, further improving its adaptability to complex building structures such as arcs and irregular shapes.

[0009] A further technical solution to the support device is that the support unit also includes a support foot, which includes multiple ribs connected to the bottom of the upright, effectively increasing the contact area between the upright and the foundation, distributing the concentrated load transmitted by the upright to a larger area of ​​the foundation, and avoiding foundation settlement or upright tilting caused by excessive local pressure.

[0010] In a further technical solution of the support device, the support unit further includes a positioning component, which is sleeved on the end of the upright and located below the adjusting block; The positioning component includes a positioning block body, and the lower end of the adjusting block is connected to an annular limiting plate. The positioning block body is provided with a limiting groove that matches the limiting plate. By matching the limiting groove of the positioning block body with the annular limiting plate at the lower end of the adjusting block, a mechanical limiting constraint is formed on the adjusting block, which effectively prevents the adjusting block from rotating unexpectedly when the support device is subjected to load or vibration, thus preventing the top support height from shifting.

[0011] In a further technical solution of the support device, the positioning component further includes a first spring, a first positioning block, a second positioning block, and a second spring; The lower end of the positioning block body is provided with an annular groove that matches the wall of the threaded hole of the upright rod. A first gap is formed between the annular groove and the inner wall of the threaded hole of the upright rod. The second positioning block is arranged in the first gap. The second spring provides a reset elastic force for the second positioning block. The annular groove forms a second gap with the outer wall of the threaded hole of the upright. The first positioning block is arranged in the second gap. The first spring provides a reset force for the first positioning block. The spring force realizes the adaptive locking of the positioning component and the threaded structure of the upright, preventing the adjusting block from loosening under load. The double positioning enhances the reliability of locking and avoids the top support height deviation caused by the failure of a single positioning. At the same time, the elastic structure allows the position adjustment to be achieved by overcoming the spring force with external force when adjustment is needed.

[0012] A further technical solution to the support device is that the first adjustment component includes a first crossbar, a threaded sleeve, and a second crossbar; The first crossbar and the second crossbar are connected to adjacent support units along the same axis. The two ends of the threaded sleeve are threaded to the free ends of the first crossbar and the second crossbar, respectively. The total length of the crossbar is continuously adjustable by using the thread transmission principle, thereby flexibly changing the distance between support units. At the same time, the rigidity of the threaded connection ensures the effective transmission of horizontal force, so that the adjusted support system can still maintain a stable stress state.

[0013] A further technical solution to the support device is that the support device also includes auxiliary components, which include a support sleeve, a support diagonal rod, and a support base; The support base is connected to the support unit, one end of the support diagonal rod is hinged to the support base, and the other end of the support diagonal rod is connected to the crossbar through the support sleeve, so that the support unit and the first adjustment component form a triangular stable structure, which effectively enhances the anti-lateral displacement ability and overall rigidity of the entire support device, and can resist the horizontal thrust generated during concrete pouring and the lateral force brought by construction load, thus preventing the frame from shifting or deforming due to horizontal force.

[0014] In a further technical solution of the support device, the first adjustment component also includes a handle, which is connected to the outer wall of the threaded sleeve.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model achieves flexible adjustment of the horizontal spacing between adjacent support units through a first adjustment component consisting of a first crossbar, a threaded sleeve, and a second crossbar. It can adapt to complex building structures such as arcs and irregular shapes without the need for additional connecting parts, solving the problem that traditional fixed-module crossbars are difficult to match irregular structures. At the same time, combined with the height adjustment structure consisting of uprights, screws, and adjustment blocks, it forms a comprehensive adjustment capability in the spatial dimension, greatly improving the adaptability range to complex building templates.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model. Example

[0019] This embodiment 1 provides a building formwork support device, such as... Figure 1As shown, it includes a support unit 1, a first adjustment component 2, and an auxiliary component 3. The support unit 1 is the main load-bearing component, the first adjustment component 2 realizes horizontal spacing adjustment, and the auxiliary component 3 enhances the overall stability. The support unit 1, the first adjustment component 2, and the auxiliary component 3 together form a support system that can adapt to complex building formwork.

[0020] Please refer to Figures 1-3 The support units 1 are arranged in an array below the building template. Each support unit 1 includes a top support 10, a second adjustment component, a support leg 16, and a connecting plate 14.

[0021] Specifically, such as Figure 2 As shown, the top support 10 is a horizontally arranged rectangular support plate. A U-shaped groove matching the building template is provided on the rectangular support plate. The U-shaped groove increases the contact area between the top support 10 and the template, so that the load can be transferred to the support unit 1 more evenly.

[0022] Please refer to the following: Figures 1-3 The second adjustment component includes a pole 15, a screw 11, and an adjustment block 12. The pole 15 serves as the vertical load-bearing frame of the support unit 1, transmitting the load from the top support 10 downwards to the foundation, while providing an adjustment track for the screw 11. The upper part of the pole 15 is a hollow steel pipe with internal threads on the inner wall of the top, and the bottom is fixedly connected to the support foot 16. The support foot 16 includes multiple ribs, which can effectively expand the contact area between the pole 15 and the foundation. A connecting plate 14 is welded to the outer side of the middle part of the pole 15 for connecting the first adjustment component 2 and other adjacent support units 1.

[0023] The screw 11 has an external thread on its outer wall, and its lower end passes through the adjusting block 12 and engages with the internal thread of the upright 15. The adjusting block 12 has a ring-shaped structure and a driving structure on its outer side. By rotating the adjusting block 12 through the driving structure, the screw 11 is driven to rise and fall along the axis of the upright 15, thereby achieving fine adjustment of the height of the top support 10. The driving structure can be manual or driven by a motor. This is existing technology and is not limited.

[0024] At the same time, such as Figures 3-4As shown, the support unit 1 also includes a positioning component 13. The positioning component 13 is sleeved on the end of the upright 15 and located below the adjusting block 12. The limiting plate 134 at the lower end of the adjusting block 12 matches the limiting groove of the positioning block body, forming a mechanical limiting constraint on the adjusting block 12, which effectively prevents the adjusting block 12 from rotating unexpectedly when the support device is subjected to load or vibration, resulting in a deviation in the top support height. Here, the positioning component 13 includes a positioning block body, a first spring 130, a first positioning block 131, a second positioning block 132, a second spring 133, and a limiting plate 134. The lower end of the positioning block body is provided with an annular groove 135, which forms a first and a second gap with the threaded hole wall of the upright 15. The first positioning block 131 is arranged in the second gap, and the first spring 130 provides a reset spring force for the first positioning block 131. The second positioning block 132 is arranged in the first gap, and the second spring 133 provides a reset spring force for the second positioning block 132. The spring drives the positioning block to fit tightly with the threaded upright, and with the mechanical limiting of the limiting plate 134 and the limiting groove, the adjusting block 12 is prevented from loosening under load, ensuring the height of the top support 10 is stable.

[0025] In this embodiment, as Figure 1 As shown, the first adjustment component 2 is connected to adjacent uprights 15 and includes a first crossbar 21, a threaded sleeve 22, a second crossbar 23, and a handle 25. The first crossbar 21 and the second crossbar 23 are connected to adjacent uprights 15 along the same axis. Specifically, one end of the first crossbar 21 is connected to a connecting plate 14 on one of the uprights 15 through a first connector 20, and one end of the second crossbar 23 is connected to a connecting plate 14 on another upright 15 through a second connector 24. The two ends of the threaded sleeve 22 are threadedly connected to the free ends of the first crossbar 21 and the second crossbar 23, respectively. The inner wall of the threaded sleeve 22 has reverse internal threads at both ends, and the handle 25 is welded to the outer side. By rotating the handle 25, the threaded sleeve 22 is driven to rotate. The meshing length of the first crossbar 21 and the second crossbar 23 is changed by the reverse thread transmission, so as to realize the stepless adjustment of the horizontal distance between adjacent support units 1, which can adapt to the size requirements of arc-shaped and irregular building structures. The rotation of the threaded sleeve 22 can be driven manually or by a motor. This is the prior art and is not limited.

[0026] In some other embodiments, to prevent the frame from shifting or deforming due to horizontal forces, the support device also includes an auxiliary component 3. The auxiliary component includes a support sleeve 30, a support diagonal rod 31, and a support base 32. The support base 32 is welded to the upright 15. One end of the support diagonal rod 31 is hinged to the support base 32, and the other end of the support diagonal rod 31 is connected to the crossbar through the support sleeve 30. The connection method is screw connection, so that the support diagonal rod 31, the upright 15, and the crossbar form a triangular stable structure, which enhances the lateral displacement resistance of the support device and resists the horizontal thrust during concrete pouring and the lateral force generated by construction load.

[0027] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
