Description

Technical Field

[0001] This application relates to the technical field of formwork support devices, and in particular to a detachable formwork support device for building construction. Background Technology

[0002] Building construction refers to the construction activities carried out by construction units on the construction site, such as site leveling, surveying and setting out, earthwork excavation, and main structure pouring. In the process of pouring the main concrete, it is necessary to first assemble the wall panels into formwork, that is, to assemble the formwork into the shape of the wall and fix it so that concrete can be poured into the interior later. The formwork needs to be supported. The formwork support device plays a key role in ensuring the stability and accuracy of the formwork during the concrete pouring process, and its performance directly affects the quality of the building structure and construction safety.

[0003] Existing methods for supporting wall formwork typically involve installing diagonal braces on one side of the formwork. One end of the diagonal brace is attached to the ground, and the other end is attached to the formwork to prevent bulging or shifting. For example, Chinese patent CN223227063U, entitled "A Building Formwork Support Device," uses this method. However, this support method generally only supports the middle section, and the support force at the top and bottom is insufficient. Therefore, we propose a detachable formwork support device for building construction. Utility Model Content

[0004] In order to improve the problem that existing support devices only support the middle part and have insufficient support at the top and bottom, this application provides a detachable formwork support device for building construction.

[0005] The technical solution of the detachable formwork support device for building construction provided in this application is as follows:

[0006] A detachable formwork support device for building construction includes a formwork body and a fixing mechanism. Multiple vertical rods are fixedly mounted on the side of the formwork body, and multiple horizontal rods are detachably connected to the outer side of each vertical rod. An adjustment mechanism is provided on the side of the fixing mechanism closest to the formwork body. One end of the adjustment mechanism is equipped with an mounting plate, and the adjustment mechanism is used to adjust the position of the mounting plate. The inner wall of the mounting plate is provided with a rotatable upper support rod and a lower support rod. The end of the upper support rod away from the mounting plate is hinged to the uppermost horizontal rod, and the end of the lower support rod away from the mounting plate is hinged to the lowermost horizontal rod. A support mechanism is provided in the middle of both the upper and lower support rods, and the support mechanism is in a pressing fit with the middle horizontal rod.

[0007] Furthermore, the fixing mechanism includes a fixing plate fixed to the ground, with a vertical plate and a reinforcing rod fixedly connected to the upper surface of the fixing plate, the reinforcing rod having a certain slope and its upper end fixedly connected to the vertical plate.

[0008] Furthermore, the adjustment mechanism includes a slide groove, which is formed inside the upright plate, and a slider is slidably connected to the inner wall of the slide groove.

[0009] Furthermore, the inner wall of the slider is threaded with a first threaded rod, one end of which is rotatably connected to the mounting plate. The side of the upright plate is provided with a slot that communicates with the slide groove, and the first threaded rod is located inside the slot.

[0010] Furthermore, the support mechanism includes an adjusting plate, the inner wall of which is slidably connected to the upper support rod, a fixed shaft is fixedly connected to the outer surface of the upper support rod, and a rotating block is rotatably connected to the outer surface of the fixed shaft.

[0011] Furthermore, a telescopic support assembly is provided on one side of the rotating block, a limit plate is fixedly connected to the outer surface of the crossbar, and the end of the telescopic support assembly away from the rotating block is located inside the limit plate.

[0012] Furthermore, the telescopic support assembly includes a second threaded rod and a rotating cylinder, the outer surface of the second threaded rod being threadedly connected to the rotating cylinder, and a lever being fixedly connected to the outer surface of the rotating cylinder.

[0013] In summary, the beneficial technical effects of this application are as follows:

[0014] 1. This detachable formwork support device for building construction uses components such as upper and lower support rods. The upper and lower support rods support the uppermost and lowermost horizontal bars respectively, thereby supporting and fixing the upper and lower positions and transferring pressure to the position of the mounting plate. The two middle horizontal bars transfer pressure to the upper and lower support rods through the support mechanism, and then fix the mounting plate through the fixing mechanism and adjustment mechanism, thus achieving the effect of fixing the upper and lower positions. This solves the problem that existing devices generally only support the middle part and the support force at the upper and lower ends is insufficient.

[0015] 2. This detachable formwork support device for building construction uses components such as an adjustment mechanism to change the position of the mounting plate, thereby supporting horizontal bars with different spacing at the top and bottom. By adjusting the position of the adjustment plate, the rotating cylinder can be inserted horizontally into the limiting plate to support horizontal bars at different heights in the middle, thus adapting to formwork bodies of different heights.

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

[0023] This application discloses a detachable formwork support device for building construction. (Refer to...) Figures 1-4The system includes a template body 1 and a fixing mechanism 4. Multiple vertical rods 2 are fixedly mounted on the sides of the template body 1, and multiple horizontal rods 3 are detachably connected to the outer sides of the vertical rods 2. An adjustment mechanism 5 is located on the side of the fixing mechanism 4 near the template body 1. One end of the adjustment mechanism 5 is equipped with an installation plate 6, and the adjustment mechanism 5 is used to adjust the position of the installation plate 6. The inner wall of the installation plate 6 is equipped with a rotatable upper support rod 7 and a lower support rod 8. The end of the upper support rod 7 away from the installation plate 6 is hinged to the uppermost horizontal rod 3, and the end of the lower support rod 8 away from the installation plate 6 is hinged to the lowermost horizontal rod 3. Support mechanisms 9 are located in the middle of both the upper and lower support rods 7 and 8, and these support mechanisms 9 engage with the middle horizontal rods 3 through compression. The template body 1 is used to enclose the concrete on the other side. Existing systems use diagonal rods to press against the middle horizontal rods 3, which can support and compress the template body 1 using multiple vertical rods 2 to achieve fixation. However, in this solution, the fixing mechanism 4 is equivalent to the existing... The supporting diagonal bars are used to resist compressive forces. The difference lies in that an upper support bar 7 and a lower support bar 8 are set between the fixing mechanism 4 and the horizontal bar 3. The upper support bar 7 and the lower support bar 8 are hinged by a pin fixed on the mounting plate 6, so that the upper support bar 7 and the lower support bar 8 can rotate in the position of the mounting plate 6. The upper support bar 7 and the lower support bar 8 support the uppermost and lowermost horizontal bars 3 respectively, thereby supporting and fixing the upper and lower positions and transmitting the pressure to the position of the mounting plate 6. There are four horizontal bars 3. The two middle horizontal bars 3 transmit the pressure to the upper support bar 7 and the lower support bar 8 through the support mechanism 9. The mounting plate 6 is then fixed by the fixing mechanism 4 and the adjusting mechanism 5. Compared with the existing one fixed point, four fixed points are increased, and the lower end is fixed, which achieves the effect of fixing the upper and lower positions. The horizontal bars 3 are fixed to the vertical bar 2 by large hexagonal bolts. During disassembly, the bolts can be directly turned to remove them.

[0024] The fixing mechanism 4 includes a fixing plate 401 fixed to the ground. A vertical plate 402 and a reinforcing rod 403 are fixedly connected to the upper surface of the fixing plate 401. The reinforcing rod 403 has a certain slope and its upper end is fixedly connected to the vertical plate 402. The fixing plate 401 has multiple threaded holes for fixing to the ground. The vertical plate 402 is used to bear the force. The reinforcing rod 403 increases the firmness of the fixing plate 401, thus forming a pressure-resistant fixing component.

[0025] The adjustment mechanism 5 includes a slide 501, which is opened inside the upright plate 402. A slider 502 is slidably connected to the inner wall of the slide 501. The slide 501 restricts the slider 502 to prevent it from deviating, allowing the slider 502 to move up and down along a specific track to adjust the vertical position of the mounting plate 6. When the height of the template used is different, the height of the mounting plate 6 can be adjusted accordingly based on the crossbar 3 of different heights.

[0026] The inner wall of the slider 502 is threaded with a first threaded rod 503. One end of the first threaded rod 503 is rotatably connected to the mounting plate 6. The side of the upright plate 402 is provided with a slot 504 that communicates with the slide groove 501. The first threaded rod 503 is located inside the slot 504. When the size of the template body 1 is different, the distance between the upper and lower crossbars 3 is also different, resulting in different inclination angles of the upper support rod 7 and the lower support rod 8, thereby changing the height of the slider 502. At the same time, the distance between the mounting plate 6 and the upright plate 402 is also different. This can be adjusted by turning the first threaded rod 503. At the same time, by turning the first threaded rod 503, pressure can be applied to the mounting plate 6 to support the template body 1. This method is suitable for templates of different sizes.

[0027] The support mechanism 9 includes an adjusting plate 901, the inner wall of which is slidably connected to the upper support rod 7. A fixed shaft 902 is fixedly connected to the outer surface of the upper support rod 7, and a rotating block 903 is rotatably connected to the outer surface of the fixed shaft 902. Threaded holes are provided on both the upper support rod 7 and the lower support rod 8. The adjusting plate 901 can be fixed to the upper support rod 7 by bolts. When adjustment is required, the position of the adjusting plate 901 on the upper support rod 7 can be changed, and the rotating block 903 can rotate on the outer surface of the fixed shaft 902.

[0028] A telescopic support assembly is provided on one side of the rotating block 903. A limit plate 907 is fixedly connected to the outer surface of the crossbar 3. The end of the telescopic support assembly away from the rotating block 903 is located inside the limit plate 907. In use, the telescopic support assembly is used to compress the crossbar 3, so that the crossbar 3 in the middle can also bear force. The telescopic support assembly can change its length. During installation, first determine the position of the crossbar 3, then determine the position of the adjusting plate 901, and try to make the adjusting plate 901 and the crossbar 3 on the same plane. Finally, rotate the rotating block 903 to drive the end of the telescopic support assembly to align with the position of the limit plate 907, and then extend the telescopic support assembly to support the upper support rod 7. The same support method is used for the lower support rod 8.

[0029] The telescopic support assembly includes a second threaded rod 904 and a rotating cylinder 905. The outer surface of the second threaded rod 904 is threadedly connected to the rotating cylinder 905. A lever 906 is fixedly connected to the outer surface of the rotating cylinder 905. In use, the rotating cylinder 905 can be rotated by lever 906, thereby adjusting the total length of the rotating cylinder 905 and the second threaded rod 904.

[0030] The implementation principle of a detachable formwork support device for building construction according to an embodiment of this application is as follows:

[0031] During installation, first attach the fixing plate 401 to the construction ground, and use the threaded holes on its surface to rigidly connect the fixing plate 401 to the ground with fasteners such as expansion bolts to ensure that the bottom does not shift.

[0032] The formwork body 1 serves as a concrete retaining structure, with multiple vertical bars 2 pre-fixed on its sides. The vertical bars 2 are evenly distributed along the height of the formwork, forming a longitudinal support frame. The horizontal bars 3 are detachably connected to the vertical bars 2 via large hexagonal bolts. A total of four horizontal bars 3 are set, which are arranged laterally along the upper, upper middle, lower middle, and lower parts of the formwork body 1, respectively. Together with the vertical bars 2, they form a longitudinally and laterally interwoven side frame of the formwork, which evenly transmits the lateral pressure of the formwork body 1 to each horizontal bar 3. The position of the horizontal bars 3 can be adjusted according to the height of the formwork body 1.

[0033] Depending on the height of the template body 1, when installing the horizontal bars 3 at the upper and lower positions, the mounting plate 6 is driven to move up and down, so that the height of the mounting plate 6 is located in the middle position of the upper and lower horizontal bars 3. At the same time, the first threaded rod 503 is turned to change the horizontal distance between the mounting plate 6 and the vertical plate 402 by means of thread transmission, which not only adapts to the spacing of the horizontal bars 3 of templates with different widths, but also applies a pre-tightening force to the mounting plate 6.

[0034] The upper support rod 7 and the lower support rod 8 are hinged to the mounting plate 6 by a pin. The end of the upper support rod 7 away from the mounting plate 6 is hinged to the uppermost horizontal bar 3, and the corresponding end of the lower support rod 8 is hinged to the lowermost horizontal bar 3, forming two fixed support points at the top and bottom, which directly bear the lateral pressure at the top and bottom of the template.

[0035] Finally, the sliding adjustment plate 901 is positioned on the upper support rod 7 and the lower support rod 8 so that it is on the same force plane as the middle crossbar 3. Then, the adjustment plate 901 is fixed to the support rod with bolts. Rotate the rotating block 903 around the fixed axis 902 so that the telescopic support assembly is aligned with the limiting plate 907 on the middle crossbar 3. Rotate the rotating cylinder 905 through the lever 906. Adjust the total length of the second threaded rod 904 and the rotating cylinder 905 by using the threaded transmission so that the end of the telescopic support assembly is embedded in the limiting plate 907 and pressed tightly to form two support points in the middle, thereby achieving fixation. At the same time, the position of the mounting plate 6 can be changed by the up-and-down moving mounting plate 6 and the adjustment mechanism 5. The position of the rotating cylinder 905 can be horizontally inserted into the interior of the limiting plate 907 by the position adjustable adjustment plate 901, so as to support the crossbar 3 at different heights in the middle, thereby adapting to the template body 1 at different heights.

[0036] During the concrete pouring process, the formwork body 1 transmits the lateral pressure to the vertical bar 2 on the surface, and the vertical bar 2 then distributes the force evenly to the four horizontal bars 3. The pressure of the uppermost and lowermost horizontal bars 3 is directly transmitted to the mounting plate 6 through the upper support bar 7 and the lower support bar 8.

[0037] The pressure of the two middle crossbars 3 is transmitted to the rotating block 903 through the telescopic support assembly, and then to the corresponding upper support rod 7 or lower support rod 8 through the adjusting plate 901, and finally to the mounting plate 6.

[0038] The mounting plate 6 transmits the concentrated pressure to the slider 502 through the first threaded rod 503. The slider 502 transmits the force to the upright plate 402 along the slide groove 501. The upright plate 402 distributes the force to the fixed plate 401 through the reinforcing rod 403. Finally, the fixed plate 401 transmits the force to the ground, realizing the gradual distribution of pressure and avoiding local overload that could cause template displacement or bulging.
