Description

Technical Field

[0001] This utility model relates to the field of building fixing support technology, specifically an adjustable building formwork fixing support. Background Technology

[0002] As a key support device in the construction of cast-in-place concrete structures, the main function of the formwork fixing bracket is to reliably connect the formwork on both sides through tie rods and apply a predetermined clamping force to resist the lateral pressure during concrete pouring, thereby ensuring the dimensional accuracy of the cross-section and surface forming quality of components such as walls and columns, and avoiding quality defects such as bulging, running out of formwork or uneven thickness.

[0003] Traditional building formwork fixing supports mostly adopt a fixed design that is either non-adjustable or difficult to adjust. The typical structure consists of pre-cut tie steel pipes (or round steel) to a specific length, which are then assembled and fixed with nuts, washers, and other loose parts. When supporting walls of different thicknesses, steel pipes of the corresponding lengths must be pre-customized or cut on-site according to the design dimensions. In other words, a single specification of steel pipe is only suitable for one wall thickness, resulting in extremely poor versatility. Construction sites often need to keep a large number of steel pipes of different lengths for selection, which not only makes material management complicated and storage costs high, but also results in extremely low turnover and serious material waste. During the formwork installation stage, operators need to accurately compare the length of the steel pipe with the wall thickness. If the length is insufficient, it cannot be installed; if the length is too long, a large amount of wood or other materials must be added to fill the gaps. This results in low installation efficiency and the risk of loosening due to gaps.

[0004] The Chinese patent published in CN223305419U describes an adjustable building formwork fixing bracket. This bracket typically employs a single support, a fixed tube, and a lifting column as its basic structure. It relies on spring-loaded blocks for height locking and snap-fit ​​adjustments for the triangular support length. The bracket adapts to the formwork thickness through the elastic expansion and contraction of the sliding rod and spring within the mounting tube. However, this design suffers from limitations such as a single adjustment dimension and insufficient locking reliability: height adjustment depends solely on the sliding cooperation between the fixed tube and the lifting column, and lateral adaptation is prone to deviation due to spring deformation; the locking structure, based on elastic elements, is susceptible to fatigue and loosening under long-term load or lateral concrete pressure; and the support system, consisting of a single triangular support, has weak resistance to bulging forces and lateral pressure, making it difficult to meet the stability requirements of complex construction scenarios. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable building formwork fixing bracket, which has the advantages of convenient operation, high efficiency and strong versatility. It solves the problems of large material waste, low turnover rate and difficulty in adapting to different column thicknesses caused by the fixed length of steel pipe in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An adjustable building formwork fixing bracket includes a load-bearing component and a fixing component. The fixing component includes two symmetrically distributed fixing frames. The inner walls of the fixing frames, which are close to each other, are each equipped with symmetrically distributed support components. Each support component includes a stud. A movable sleeve is threaded onto the outer wall of the stud. The outer wall of the movable sleeve has several equally spaced grooves. A locking component is fixed to the outer wall of the movable sleeve. The locking component includes a fixing sleeve fixed to the edge of the outer wall of the movable sleeve. The outer wall of the fixing sleeve has several equally spaced sliding holes, which correspond one-to-one with the grooves. The locking component also includes a fixing ring rotatably mounted on the outer wall of the fixing sleeve and a fixing pin slidably mounted on the inner wall of the sliding holes. The outer wall of the fixing pin has several equally spaced grooves. The inner wall of each groove has a second inclined surface. The outer wall of the fixing pin has a first inclined surface, which fits into the second inclined surface. The lower end of the fixing pin abuts against the outer wall of the stud.

[0007] Preferably, the load-bearing component includes a base and support columns fixed to the upper end of the base and symmetrically distributed, with several fixing components distributed vertically on the outer wall of the support columns.

[0008] Preferably, the fixing component further includes sliding sleeves that are fixed to the outer wall of the fixing frame and symmetrically distributed, with the inner wall of the sliding sleeves conforming to the outer wall of the support column.

[0009] It is worth noting that: the base provides stable support for the entire support structure, preventing it from tipping over during column pouring; several fixing components distributed on the upper and lower parts of the outer wall of the support column can be adjusted in height by sliding along the outer wall of the support column via a sliding sleeve, adapting to building columns of different heights; the inner wall of the sliding sleeve fits against the outer wall of the support column, ensuring that the fixing components remain stable after adjustment and will not shift.

[0010] Preferably, screw holes one and two are provided through the front and rear edges of the fixing frame. Screw hole one corresponds to screw hole two of the adjacent fixing frame. A bolt is installed in the internal thread of screw hole one. The bolt passes through screw hole one and is threaded into screw hole two of the adjacent fixing frame.

[0011] It is worth noting that adjacent fixing frames can be quickly connected to form a fixed frame by screw holes one and two and bolts. The bolts pass through screw hole one of the fixing frames and are screwed into screw hole two of the adjacent fixing frames. Assembly can be completed without complicated tools, making the operation convenient. Moreover, the threaded connection is firm, which can prevent the fixing frames from loosening during column pouring, improve construction efficiency, and can be disassembled and reused to improve turnover rate.

[0012] Preferably, the inner walls of the adjacent ends of the fixed frames are provided with sliding grooves, and the support assembly also includes a sliding seat that is slidably installed in the sliding groove, with a stud hinged to one end of the sliding seat inside the fixed frame.

[0013] It is worth noting that the sliding seat can slide along the groove of the fixed frame, driving the hinged stud to adjust its lateral position; in conjunction with the movable sleeve on the outer wall of the stud, the distance between the support component and the template can be further fine-tuned to adapt to building columns of different thicknesses; the sliding design of the sliding seat combined with the hinged structure of the stud greatly enhances the versatility of the support.

[0014] Preferably, the end of the movable sleeve is rotatably mounted with a connecting seat, and the outer wall contour of the edge of the fixed sleeve is hexagonal.

[0015] It is worth noting that the connecting seat at the end of the movable sleeve can be directly connected to the building formwork. This allows for the connection and fixing of the building formwork without affecting the rotation of the movable sleeve. The hexagonal outer wall of the fixed sleeve is easy to clamp with tools such as wrenches, making it easier to rotate the movable sleeve. This allows for quick adjustment of the length of the support components, reducing operational difficulty and improving adjustment efficiency.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a stable installation foundation for the support component through symmetrically distributed fixing frames, forming a clamping frame for the building template from both sides. In the support component, the stud and the movable sleeve are threaded together. Rotating the movable sleeve adjusts their relative lengths, thereby changing the overall support distance of the support component. It does not rely on steel pipes of fixed length and can flexibly adapt to building columns of different thicknesses. The locking component on the outer wall of the movable sleeve can lock the adjusted position: the fixed sleeve is fixed to the movable sleeve, and its sliding hole corresponds to the slot hole of the movable sleeve. When the fixed ring is rotated, the inclined surface one of the fixed pin engages with the inclined surface two of the slot, pushing the fixed pin to slide along the sliding hole and press against the outer wall of the stud, realizing a reliable lock between the stud and the movable sleeve and preventing loosening during the support process. The entire adjustment and locking process does not require complicated tools, is convenient to operate and highly efficient, and can be disassembled and reassembled repeatedly, greatly improving the turnover rate of the support and matching the advantages of convenient operation, high efficiency and strong versatility of the device.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To address the problems of significant material waste, low turnover rate, and difficulty in adapting to different column thicknesses caused by the fixed length of steel pipes in existing technologies, the following technical solution is proposed. Please refer to [link / reference]. Figures 1-5 ; An adjustable building formwork fixing bracket includes a load-bearing component and a fixing component. The fixing component includes two symmetrically distributed fixing frames 201. Symmetrically distributed support components are installed on the inner walls of the adjacent ends of the fixing frames 201. Each support component includes a stud 302. A movable sleeve 303 is threaded onto the outer wall of the stud 302. Several equally spaced, circumferential slots 305 are perforated on the outer wall of the movable sleeve 303. A locking component is fixedly connected to the outer wall of the movable sleeve 303. The locking component includes a fixing sleeve 401 fixed to the edge of the outer wall of the movable sleeve 303. The outer wall is provided with several equally spaced sliding holes 403, which correspond one-to-one with the slots 305. The locking assembly also includes a fixing ring 402 rotatably mounted on the outer wall of the fixing sleeve 401, and a fixing pin 404 slidably mounted on the inner wall of the sliding hole 403. The outer wall of the fixing pin 404 is provided with several equally spaced slots 405, and the inner wall of each slot 405 is provided with a second inclined surface 407. The outer wall of the fixing pin 404 is provided with a first inclined surface 406, which fits against the second inclined surface 407. The lower end of the fixing pin 404 abuts against the outer wall of the stud 302.

[0021] The symmetrically distributed fixing frames 201 provide a stable installation foundation for the support assembly, forming a clamping frame for the building formwork from both sides. In the support assembly, the studs 302 and movable sleeves 303 are threaded together; rotating the movable sleeve 303 adjusts their relative lengths, thereby changing the overall support distance of the support assembly. This eliminates the need for fixed-length steel pipes and allows for flexible adaptation to building columns of varying thicknesses. The locking component on the outer wall of the movable sleeve 303 locks the adjusted position: the fixed sleeve 401 is fixedly connected to the movable sleeve 303, and its sliding hole 403 engages with the movable sleeve 303. Corresponding to the slot 305 of the movable sleeve 303, when the fixed ring 402 is rotated, the inclined surface 406 of the fixed pin 404 engages with the inclined surface 407 of the slot 405, driving the fixed pin 404 to slide along the sliding hole 403 and press against the outer wall of the stud 302, thus achieving reliable locking between the stud 302 and the movable sleeve 303 and preventing loosening during the support process; the entire adjustment and locking process does not require complicated tools, is convenient to operate and highly efficient, and can be disassembled and reassembled repeatedly, greatly improving the turnover rate of the support, which fits the advantages of convenient operation, high efficiency and strong versatility of the device.

[0022] Please see Figures 1-3 The supporting components include a base 101 and symmetrically distributed support columns 102 fixed to the upper end of the base 101. Several fixing components are installed on the outer wall of the support columns 102. The fixing components also include symmetrically distributed sliding sleeves 203 fixed to the outer wall of the fixing frame 201. The inner wall of the sliding sleeves 203 fits against the outer wall of the support columns 102. The base 101 provides stable support for the entire support, preventing the support from tipping over during the column pouring process. The several fixing components distributed on the outer wall of the support columns 102 can be adjusted in height by sliding along the outer wall of the support columns 102 via the sliding sleeves 203 to adapt to building columns of different heights. The inner wall of the sliding sleeves 203 fits against the outer wall of the support columns 102, ensuring that the fixing components are stable in position after adjustment and will not shift.

[0023] Both ends of the fixing frame 201 have threaded holes 204 and 205. Threaded holes 204 and 205 are drilled through each edge. Threaded holes 204 correspond to threaded holes 205 of adjacent fixing frames 201. Bolts 206 are threaded into threaded holes 204, passing through threaded holes 204 and threaded into threaded holes 205 of adjacent fixing frames 201. Adjacent fixing frames 201 can be quickly connected into a fixed frame shape via threaded holes 204, threaded holes 205, and bolts 206. Bolts 206 pass through threaded holes 204 of one fixing frame 201 and are screwed into threaded holes 205 of the adjacent fixing frame 201. Assembly can be completed without complicated tools, making operation convenient. The threaded connection is firm, preventing the fixing frames 201 from loosening during column pouring, improving construction efficiency. It can also be disassembled and reused, increasing turnover rate.

[0024] Please see Figure 4The inner walls of the fixed frames 201, which are close to each other, are provided with sliding grooves 202. The support assembly also includes a sliding seat 301 that is slidably installed in the sliding groove 202. The end of the sliding seat 301 located inside the fixed frame 201 is hinged to a stud 302. The sliding seat 301 can slide along the sliding groove 202 of the fixed frame 201, thereby driving the hinged stud 302 to adjust its lateral position. With the help of the movable sleeve 303 on the outer wall of the stud 302, the distance between the support assembly and the template can be further fine-tuned to adapt to building columns of different thicknesses. The sliding design of the sliding seat 301 and the hinged structure of the stud 302 greatly enhance the versatility of the support.

[0025] Please see Figure 5 The end of the movable sleeve 303 is rotatably mounted with a connecting seat 304, and the outer wall of the fixed sleeve 401 has a hexagonal outline at the edge. The connecting seat 304 at the end of the movable sleeve 303 can be directly connected to the building template, and the building template can be connected and fixed without affecting the rotation of the movable sleeve 303. The hexagonal outer wall of the fixed sleeve 401 is easy to clamp with tools such as wrenches, making it easier to rotate the movable sleeve 303, quickly adjusting the length of the support component, reducing the difficulty of operation, and improving the adjustment efficiency.

[0026] Working principle: Foundation positioning and height adjustment: First, place the base 101 of the load-bearing component at the designated construction position to provide stable support for the entire support and prevent it from tipping over during pouring; according to the height requirements of the building column, push the sliding sleeve 203 of the fixing component to slide along the outer wall of the support column 102 to adjust the height of the several fixing components distributed vertically. After adjustment, the inner wall of the sliding sleeve 203 fits against the outer wall of the support column 102 to ensure that the position of the fixing component is stable and does not shift.

[0027] Fixed frame assembly: Connect adjacent fixed frames 201 with connectors, pass bolts 206 through the screw hole 204 of one fixed frame 201 and screw them into the screw hole 205 of the adjacent fixed frame 201, quickly connect multiple fixed frames 201 into a fixed frame that surrounds the building column, and the threaded connection can prevent the frame from loosening during pouring.

[0028] Coarse adjustment of the support component position: Push the sliding seat 301 of the support component to slide along the groove 202 on the inner wall of the fixing frame 201, which will drive the stud 302 hinged to the sliding seat 301 to move laterally, and initially adjust the lateral distance between the support component and the building formwork to match the approximate thickness of the column.

[0029] Fine-tuning of support length and docking with template: Using the hexagonal outer wall of the fixed sleeve 401 (which facilitates tool clamping and leverage), rotate the movable sleeve 303, and use the threaded engagement between the stud 302 and the movable sleeve 303 to change their relative lengths, thereby precisely adjusting the overall support distance of the support assembly; until the connecting seat 304, which is rotatably installed at the end of the movable sleeve 303, fits against the outer wall of the building template, completing the docking of the support assembly with the template.

[0030] Support locking: Rotate the fixing ring 402 of the locking assembly. At this time, the inclined surface 406 of the fixing pin 404 engages with the inclined surface 407 of the groove 405 on its outer wall, pushing the fixing pin 404 to slide along the sliding hole 403 of the fixing sleeve 401 (corresponding to the groove 305 of the movable sleeve 303). Finally, the lower end of the fixing pin 404 abuts against the outer wall of the stud 302, locking the relative position of the stud 302 and the movable sleeve 303, preventing loosening during the support process. The whole process does not require complicated tools, and completes the reliable fixing of the bracket to the building formwork. It can meet the casting requirements of columns of different thicknesses, and can be disassembled and reassembled afterward.

[0031] Please see Figure 6 The building template used in conjunction with this utility model is different from ordinary building templates. The edge of the building template 11 is provided with connecting ears 22 that are connected to the connecting seat 304.
