Description

Technical Field

[0001] This invention belongs to the field of template support technology, and more specifically, relates to a template support device and method for irregularly shaped columns. Background Technology

[0002] Structural columns are reinforced concrete columns installed in the walls of multi-story brick-concrete structures to enhance the overall integrity and stability of buildings. These columns connect to the ring beams on each floor, forming a spatial frame that resists bending and shear, making them an effective measure to prevent building collapse. With the development of the construction industry, various irregularly shaped columns have emerged, and traditional support and fixing components for rectangular and circular columns are no longer sufficient.

[0003] In existing technologies, traditional column formwork fixing methods 1 (threaded rod + column clamp + fastener reinforcement) waste a large number of threaded rods, require the rental of a large number of steel pipes and fasteners, and are expensive; method 2 (rectangular column formwork clamp reinforcement) can only reinforce regular squares, which is very limited. These problems lead to slow construction progress and low work efficiency. Chinese patent CN209053431U discloses a column formwork fixing device, which solves the problem of wasting a lot of manpower and material resources in the formwork installation of existing technologies. It has the beneficial effects of convenient installation, easy storage, transportation and management. The solution is as follows: A column formwork fixing device includes modules that can be set around the formwork. Each set of modules includes a first reinforcing strip and a second reinforcing strip arranged in a cross pattern. One end of one of the first reinforcing strip and the second reinforcing strip is bent so that the end of the other set of modules passes through the bend. The two sets of modules are connected to each other, and both the first reinforcing strip and the second reinforcing strip are provided with protrusions. However, this device can only fix regular rectangular columns. At the same time, this device cannot position and monitor the deformation of the fasteners during the tightening process. Chinese patent CN216360897U discloses a structural column formwork fixing device, which includes: a clamp, which is U-shaped; a top rod, threadedly connected to three side plates of the clamp and perpendicular to the side plates; and a top plate, fixedly connected to one end of the top rod located inside the clamp and perpendicular to the top rod. This structural column formwork fixing device can quickly fix the formwork of structural columns at their ends without damaging the wall, thus improving the construction efficiency of structural columns. However, this device can only fix regular rectangular columns, resulting in wasted top support. Similarly, this device cannot position or monitor the deformation of fasteners during the tightening process.

[0004] Based on the above-mentioned defects and shortcomings, there is an urgent need in this field to propose a new type of irregular column template support device to adapt to different irregular columns, and at the same time to position and monitor the deformation of fasteners during the fastening process.

The structure and specific configuration of key components such as the hinged telescopic linkage unit, locking unit, and deformation monitoring module are studied and designed. This effectively solves the problem of poor adaptability of existing support devices. Furthermore, the structural design can be adjusted according to the shape of the irregularly shaped column to adapt to different cross-sectional shapes. Simultaneously, the positioning and deformation monitoring of fasteners can be performed during the fastening process, thereby better supporting the template and preventing template deformation and tilting.

[0013] The first and second connecting rods are arranged overlappingly, and the first double-ended fastener passes through the first slide groove, the second slide groove, and the first pad. Correspondingly, the second double-ended fastener passes through the first slide groove, the second slide groove, and the second pad. In this way, the first and second double-ended fasteners are loosened, and the overlap length of the first and second connecting rods is adjusted to a specified position. Then, the first and second double-ended fasteners are tightened to achieve the length adjustment of the telescopic connecting rod assembly.

[0014] As a further preferred embodiment, the end of the first connecting rod that does not overlap with the second connecting rod is provided with a first rotating waist hole, and the end of the second connecting rod that does not overlap with the first connecting rod is provided with a second rotating waist hole.

[0016] As a further preferred embodiment, a tapered positioning elastic element is movably provided on the fastening shaft of the two third double-headed fasteners. This tapered positioning elastic element is used to engage with the gap between the two wooden blocks at the top of the two adjacent sides to initially fix the position of the two telescopic linkage assemblies.

[0017] As a further preferred embodiment, the first connecting rod is also provided with a secondary positioning component. The secondary positioning component includes a sliding buckle on the first connecting rod, a push rod passing through the first connecting rod, and a vacuum suction cup at the end of the push rod. The sliding buckle is slidably disposed on the first connecting rod, and the push rod is slidably connected to the sliding buckle. The vacuum suction cup is disposed at one end near the wood, and the end of the push rod without the vacuum suction cup extends outside the first connecting rod. In this way, the vacuum suction cup is aligned with the positioning point on the wood, and the push rod is pushed to compress the vacuum suction cup, thereby fixing the vacuum suction cup to the wood and achieving secondary fixation of the telescopic connecting rod assembly position.

[0018] As a further preferred embodiment, the locking unit includes a fourth double-ended fastener, a pull rod bolt, and a bolt sleeve. The fourth double-ended fastener passes through the second rotating waist hole, and the fastening shaft of the fourth double-ended fastener is provided with a fastening hole through which the pull rod bolt passes. The bolt sleeve is threadedly connected to the pull rod bolt and is used to tighten or loosen two adjacent fourth double-ended fasteners.

[0019] As a further preferred embodiment, the deformation monitoring module includes an ultrasonic transmitter and an ultrasonic receiver disposed on the telescopic link assembly, wherein at least two ultrasonic receivers are disposed on each telescopic link assembly.

[0020] According to another aspect of the present invention, a method for supporting irregularly shaped column templates is also provided, comprising the following steps:

[0021] Step 1: Determine the number of hinged telescopic linkage units for each cross section and the number of fastening cross sections based on the shape and scale of the irregular column. Adjust the length of the hinged telescopic linkage units so that the length of each side of the hinged telescopic linkage unit is adapted to the corresponding side length of the irregular column.

[0022] Step 2: Determine the positioning point group for the installation of the hinged telescopic linkage unit on each fastening cross section.

[0023] Step 3: Secure one articulated telescopic link unit on one of the cross sections to the first positioning point for initial fixation of the articulated telescopic link unit; secure the articulated telescopic link unit to the second positioning point for secondary fixation of the articulated telescopic link unit.

[0024] Step 4: Use locking units to lock adjacent articulated telescopic linkage units, and connect multiple articulated telescopic linkage units in sequence to form a ring structure that fastens the corresponding cross-sections;

[0025] Step 5: Repeat steps 3 and 4 until all the articulated telescopic linkage units of all cross sections are locked;

[0026] Step 6: Use a deformation monitoring module to monitor the deformation of the template at different heights and cross-sections.

[0027] In summary, compared with the prior art, the above-described technical solutions conceived by this invention mainly possess the following technical advantages:

[0028] 1. This invention studies and designs the structure and specific arrangement of its key components, such as the articulated telescopic linkage unit, locking unit, and deformation monitoring module. Correspondingly, it can effectively solve the problem of poor adaptability of the support device in the prior art. At the same time, it can adjust the structural design according to the shape of the irregular column to adapt to different cross-sectional shapes. In addition, it can also position and monitor the deformation of the fasteners during the fastening process, thereby better supporting the template and avoiding template deformation and tilting.

[0029] 2. This invention can fix and lock concrete column formwork, improving construction efficiency and quality. Its simple structure, rapid and convenient fabrication, and streamlined construction process for various specifications of irregularly shaped columns are possible. Tools are reusable, further enhancing construction efficiency. The advantages of this invention are cost savings, improved construction efficiency and quality, and applicability to the construction of various specifications of irregularly shaped columns.

[0030] 3. The support module of this invention has an overlapping structure, with one end of the connecting groove being the outer end. The two plate assemblies are paired opposite each other, and spacers are provided between the plate assemblies. Bolts pass through the sliding grooves of the plate assemblies to clamp the spacers, so that the two plate assemblies form an integral rod with an adjustable length. This structural design allows the expansion joint to be freely adjusted according to the shape of the irregular column, thereby better supporting the concrete column formwork.

[0031] 4. The number of expansion joints in this invention is consistent with the number of sides of the irregular column. Adjacent expansion joints are connected end-to-end into a chain via connecting plates and bolts, and are fastened to the outside of the concrete column formwork. This connection method allows the chain to fit tightly against the concrete column formwork, thereby better supporting the formwork and preventing deformation and tilting of the formwork.

[0032] 5. In this invention, connecting plates can be removed between some expansion joints, and bolts can be replaced with perforated bolts. The perforated bolt has a hole in its center to allow for the installation of tie rod bolts and bolt sleeves. Tightening the distance between two perforated bolts secures the chain of multiple expansion joints, thus fixing and locking the concrete column formwork. This fastening method not only better secures the formwork but can also be adjusted as needed, thus better adapting to irregularly shaped column formwork.

[0033] 6. After two positioning operations, the present invention can ensure that the fastening cross section is the set fastening cross section, thereby ensuring the effectiveness of the support and avoiding the offset of the support device, which would cause compression and displacement of the irregular column.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0040] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown in the figure, an embodiment of the present invention provides a support device for irregular column templates. The irregular column template includes a template 2 and timber 3 arranged circumferentially along the template 2. It includes: a plurality of support modules arranged circumferentially along the cross-section of the timber 3 and a deformation monitoring module (not shown in the figure). The support module includes a hinged telescopic link unit and a locking unit. The plurality of hinged telescopic link units are connected in sequence to form a ring structure. The hinged telescopic link units are telescopically adjustable to adapt to different cross-sections of the timber 3. The locking unit is used to lock two adjacent hinged telescopic link units to achieve a tight support for the irregular column template. The deformation monitoring module is provided on the hinged telescopic link unit and is used to monitor the deformation of the template 2 at different heights and cross-sections.

[0041] In this invention, the irregular column template includes a concrete column 1, a template 2 arranged around the concrete column 1, and multiple wooden beams 3 arranged around the template 2. The template 2 has wooden beams at the vertices of two adjacent sides, so that the two wooden beams form a V-shaped gap at the vertices of the two adjacent sides.

[0042] In one embodiment of the present invention, the hinged telescopic linkage unit includes two telescopic linkage assemblies with identical structures, and the two telescopic linkage assemblies are hinged together by a connecting plate assembly. The telescopic linkage assembly includes a first link 401, a second link 402, a first pad 403, a second pad 404, a first slide groove 405, and a second slide groove 406. The first link 401 contains the first pad 403 and has the first slide groove 405, allowing the first pad 403 to slide along the first slide groove 405. The second link 402 contains the second pad 404 and has the second slide groove 406, allowing the second pad 404 to slide along the second slide groove 406. The first link 401... The first double-ended fastener 407 is arranged overlapping with the second connecting rod 402 and passes through the first sliding groove 405, the second sliding groove 406 and the first pad 403. Correspondingly, the second double-ended fastener 408 passes through the first sliding groove 405, the second sliding groove 406 and the second pad 404. In this way, the first double-ended fastener 407 and the second double-ended fastener 408 are loosened, and the overlap length of the first connecting rod 401 and the second connecting rod 402 is adjusted to a specified position. Then, the first double-ended fastener 407 and the second double-ended fastener 408 are tightened to realize the length adjustment of the telescopic connecting rod assembly.

[0043] More specifically, both the first link 401 and the second link 402 are two parallel connecting plates with overlapping arrangement. By placing pads between the overlapping plates, after the overlap length of the first link 401 and the second link 402 is adjusted to the correct position, the double-ended fasteners will not squeeze or deform the first link 401 and the second link 402 during the tightening process. At the same time, it can also ensure multi-point support for the first link 401 and the second link 402, thereby ensuring the stability of the overall structure.

[0044] In one embodiment of the present invention, the end of the first connecting rod 401 that does not overlap with the second connecting rod 402 is provided with a first rotating waist hole 409, and the end of the second connecting rod 402 that does not overlap with the first connecting rod 401 is provided with a second rotating waist hole 410. The first rotating waist hole 409 is connected to the connecting plate assembly, and the second rotating waist hole 410 is connected to the locking unit.

[0045] In one embodiment of the present invention, the connecting plate assembly includes a rotating connecting plate 411 disposed above and below the first connecting rod 401, and a third double-headed fastener 412 passing through a set of corresponding first rotating waist holes 409. The third double-headed fastener 412 also passes through two rotating connecting plates 411. In this way, by setting the tightening value of the third double-headed fastener 412, the first connecting rod 401 rotates around the third double-headed fastener 412.

[0046] In one embodiment of the present invention, to ensure that the telescopic linkage assemblies with the same cross-section do not shift during the fastening process, i.e., the fastening force applied to the irregular column by the telescopic linkage assemblies on the same plane during the fastening process is perpendicular to its plane, the present invention provides a positioning and fixing module (not shown in the figure) to achieve two positioning of the telescopic linkage assemblies during the installation process. Specifically, a conical positioning elastic element is movably provided on the fastening shaft of the two third double-headed fasteners 412. This conical positioning elastic element is used to engage with the gap between the two wooden blocks at the top ends of two adjacent sides to initially fix the position of the two telescopic linkage assemblies. The first connecting rod 401 is also provided with a secondary positioning component. This secondary positioning component includes a sliding buckle on the first connecting rod 401, a push rod passing through the first connecting rod 401, and a vacuum suction cup at the end of the push rod. The sliding buckle is slidably mounted on the first connecting rod 401, and the push rod is slidably connected to the sliding buckle. The vacuum suction cup is located near the end of the wooden block, and the end of the push rod without the vacuum suction cup extends beyond the first connecting rod 401. In this way, the vacuum suction cup is aligned with the positioning point on the wooden block, and the push rod is pushed to compress the vacuum suction cup, thus fixing the vacuum suction cup to the wooden block and achieving secondary fixation of the telescopic connecting rod assembly position. More specifically, the initial fixing point is the first positioning point, and the secondary fixing point is the second positioning point. These three points can determine a unique plane. Therefore, after two positioning operations, it can be ensured that the tightened cross-section is the set tightened cross-section, thereby ensuring the effectiveness of the support and preventing the support device from shifting, which could cause compression or displacement of the irregularly shaped column.

[0047] In one embodiment of the present invention, the locking unit includes a fourth double-ended fastener 413, a pull rod bolt, and a bolt sleeve 414. The fourth double-ended fastener 413 is disposed through the second rotating waist hole 410. The fastening shaft of the fourth double-ended fastener 413 is provided with a fastening hole through which the pull rod bolt passes. The bolt sleeve 414 is threadedly connected to the pull rod bolt and is used to tighten or loosen two adjacent fourth double-ended fasteners 413.

[0048] In one embodiment of the present invention, the deformation monitoring module includes an ultrasonic transmitter and an ultrasonic receiver disposed on the telescopic link assembly, wherein at least two ultrasonic receivers are disposed on each telescopic link assembly. More specifically, in the present invention, the shape of the measured cross section is determined by the information detected by the ultrasonic receivers, and the shape of the measured cross section is compared with the shape of the designed cross section to achieve deformation monitoring of the irregular column.

[0049] The device of the present invention for supporting irregularly shaped column templates includes the following steps:

[0050] Step 1: Based on the irregular column structure, the main body is sealed with formwork and timber. After the rebar is tied, the formwork support and fixing begin. The number of hinged telescopic linkage units for each cross-section and the number of fastened cross-sections are determined according to the shape and scale of the irregular column. The length of the hinged telescopic linkage units is adjusted so that the length of each side of the unit is adapted to the corresponding side length of the irregular column. In one embodiment of the invention, fixing begins every 1 meter from the bottom of the column.

[0051] Step Two: Determine the positioning point group for the hinged telescopic linkage unit on each fastening cross section. This positioning point group includes a first positioning point and a second positioning point. The first positioning point is located between the two wooden blocks at the top of two adjacent sides of the cross section, and the second positioning point is located on the wooden blocks at the non-vertical positions of two adjacent sides of the cross section. More specifically, the tapered positioning elastic element is snapped into the designated position between the two wooden blocks at the top of the two adjacent sides, i.e., the first positioning point position. Since the tapered positioning elastic element is elastic, it deforms during the compression process, and the restoring force of the deformation fixes and positions the vertices of the hinged telescopic linkage unit.

[0052] Step 3: Secure one hinged telescopic link unit on one of the cross-sections to the first positioning point for initial fixing of the hinged telescopic link unit. Secure the hinged telescopic link unit to the second positioning point for secondary fixing. More specifically, match the number of telescopic components according to the number of sides of the irregular column. Connect adjacent telescopic components to form a chain with ends connected by connecting plates and bolts, and secure it to the outside of the concrete column formwork. More specifically, align the vacuum suction cup with the positioning point on the wooden block, push the push rod to compress the vacuum suction cup, so that the vacuum suction cup is fixed to the wooden block, realizing secondary fixing of the telescopic link assembly position.

[0053] Step 4: Use locking units to lock adjacent articulated telescopic link units. Multiple articulated telescopic link units are connected in sequence to form a ring structure that fastens the corresponding cross-sections. Through bolt + groove cooperation, make the length of each column side equal to the length of a set of telescopic components, and then tighten the bolts.

[0054] Step 5: Repeat steps 3 and 4 until all the articulated telescopic linkage units of all cross sections are locked;

[0055] Step Six: Monitor the deformation of the template 2 at different heights using a deformation monitoring module. The deformation monitoring module includes an ultrasonic transmitter and ultrasonic receivers mounted on the telescopic link assemblies, with at least two ultrasonic receivers on each telescopic link assembly. More specifically, the shape of the measured cross-section is determined using information detected by the ultrasonic receivers, and the shape of the measured cross-section is compared with the designed cross-section shape to monitor the deformation of the irregularly shaped column.

[0056] Of course, for some expansion joints, the connecting plates can be removed and the bolts replaced with perforated bolts. The perforated bolts have a hole in the center to allow for the installation of tie rod bolts and sleeves. Tightening the distance between two perforated bolts secures the chain of multiple expansion joints, thus fixing and locking the concrete column formwork. Fine adjustments are made according to the angle of the irregular column using the expansion joint grooves between each group.

[0057] Step 7: After the concrete has solidified and the demolding period has arrived, loosen the sleeves to allow the formwork support tools to detach, and remove the formwork and timber.

[0058] Step 8: Reuse the formwork support tools for the next construction area's irregular columns.

[0059] The irregular column formwork support device and method of the present invention can realize the support and fixation of irregular column formwork, improve construction efficiency and quality, and at the same time reduce the amount and cost of formwork support tools.

[0060] In summary, this invention aims to solve the problems existing in the construction of column formwork fixing in the metallurgical and construction industries. Traditional methods for fixing irregularly shaped column formwork waste a large number of threaded rods, require the rental of a large number of steel pipes and fasteners, and are costly. Rectangular column formwork clamp reinforcement can only reinforce regular square shapes, which is very limited. This invention provides a support device and method for irregularly shaped column formwork, consisting of telescopic components, connecting plates, bolts, perforated bolts, tie rod bolts, and sleeves. The telescopic components consist of four plates and multiple pads, which can be adjusted according to the number of sides of the irregularly shaped column. The connecting plates and bolts connect the telescopic components into a chain, which is fastened to the outside of the concrete column formwork. The chain composed of multiple telescopic components needs to be tensioned, which can be achieved using perforated bolts, tie rod bolts, and sleeves. This device can fix and lock concrete column formwork, improving construction efficiency and quality. Its structure is simple, quick to manufacture, and convenient, enabling streamlined construction of various specifications of irregularly shaped columns. Tools can be reused, while improving construction efficiency. The advantages of this invention are cost savings, improved construction efficiency and quality, and applicability to the construction of various specifications of irregularly shaped columns.

[0061] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
