Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an adjustable anchoring device and anchoring method for post-cast strips. Background Technology

[0002] In building construction, post-cast strips are an important structural measure used to address issues related to structural deformation, shrinkage, and temperature stress. During the construction of post-cast strips, reliable anchoring and support of the concrete structures on both sides are necessary to prevent displacement, deformation, or formwork failure during the pouring process.

[0003] Currently, post-cast strip anchorage is mostly achieved through on-site welding, tying of reinforcing bars, or pre-embedded fasteners. Specifically, during construction, transverse support reinforcing bars are first welded to the outside or ends of the formwork on both sides of the post-cast strip, or external struts are connected through pre-embedded sleeves or steel plates. These fixed components are used to form top or pull constraints on the formwork on both sides, thereby limiting the lateral displacement of the formwork during concrete pouring and achieving limited anchorage.

[0004] In actual construction, some post-cast strips have a stepped structure, meaning they narrow along the depth direction. This results in the internal support area having less operational space in the depth direction than the outer opening. Existing anchoring devices are mostly fixed, allowing only long-distance support from the outside. They cannot directly support the interior from the outer opening through the stepped narrowing area, causing the support point to be far from the concrete load-bearing surface. This leads to insufficient support stiffness, making the formwork prone to displacement and bulging under the lateral pressure of concrete pouring. After casting, large-scale chiseling and repair of the out-of-tolerance areas are often required. Furthermore, a single set of devices is difficult to apply to post-cast strips of different sizes for reuse.

[0005] Therefore, there is an urgent need to propose an adjustable anchoring device and anchoring method for post-cast strips to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustable anchoring device and anchoring method for post-cast strips, which can solve the problems of existing devices being unable to penetrate deep into the stepped post-cast strip for direct support, insufficient support rigidity, easy mold displacement and bulging, and difficulty in reuse.

[0007] Based on the above concept, the technical solution adopted by this invention is as follows: An adjustable anchoring device for post-cast strips, comprising: The main frame is a rectangular ring structure formed by four frame strips connected end to end. Each frame strip has a strip hole extending along its length, and each strip hole connects to the inner and outer sides of the main frame. An adjustable panel is positioned adjustablely in the adjustment space enclosed by the main frame along both the length and width directions of the main frame. The adjustable panel has at least three threaded holes through it along the thickness direction, and the at least three threaded holes are arranged in a non-linear manner. Multiple first adjustment components correspond one-to-one with multiple strip holes. Each first adjustment component includes a first adjustment member and a locking member. The first adjustment member passes through the strip hole and is connected to the adjustable panel. The locking member is screwed to the first adjustment member and abuts against the side of the frame strip away from the adjustment space. The limiting panel has at least three mounting holes extending through it along the thickness direction, and the mounting holes correspond one-to-one with the threaded holes. At least three second adjusting members are screwed into the threaded holes one by one and rotatably connected to the limiting panel through the corresponding mounting holes.

[0008] Furthermore, the adjustable panel has a rectangular plate structure, and the outer contour of the adjustable panel and the inner cavity contour enclosed by the four frame strips of the main frame are proportionally reduced in both length and width directions.

[0009] Furthermore, the maximum vertical distance between the outer surface of each side of the adjustable panel and the inner surface of the corresponding frame strip is 50mm-150mm.

[0010] Furthermore, the frame strip is provided with at least two strip-shaped holes at intervals along its length, and the first adjustment component is provided in a one-to-one correspondence with each of the strip-shaped holes.

[0011] Furthermore, a bearing is fixedly installed on the limiting panel, and the inner ring of the bearing is interference-fitted with the second adjusting member.

[0012] Furthermore, a screw head is provided at the end of the second adjusting member away from the limiting panel.

[0013] Furthermore, the four corners of the main frame are each welded together from two adjacent frame strips, and each corner is provided with a reinforcing corner plate on its outer side, which is welded to the corresponding two frame strips.

[0014] Furthermore, the main frame is made of steel.

[0015] A method for anchoring post-cast strips, using the aforementioned adjustable anchoring device for post-cast strips, includes the following steps: S1. Fix the main frame to the walls on both sides of the post-pouring strip so that the adjustment space enclosed by the main frame corresponds to the post-pouring strip area to be poured. S2. Rotate each of the second adjusting components to drive the limiting panel to move relative to the adjustable panel along the thickness direction until the limiting panel reaches the preset limiting working surface position. S3. Adjust the position of the adjustable panel in the length and width directions within the main frame using the first adjustment component, and then tighten the locking parts to fix the adjustable panel relative to the main frame. S4. Pour concrete in the post-pouring strip area, using the limiting panel as the limiting interface during pouring. S5. Once the concrete reaches the preset strength, rotate the second adjusting component in the opposite direction to detach the limiting panel from the concrete surface, and then remove the main frame, adjustable panel, limiting panel, first adjusting component, and second adjusting component as a whole.

[0016] Furthermore, in step S1, the main frame is fixed to the walls on both sides of the post-cast strip by tie bolts.

[0017] The beneficial effects of this invention are: This invention proposes an adjustable anchoring device for post-pouring strips. By fixing a large main frame to the outer opening of the post-pouring strip, a smaller limiting panel is driven independently through the narrowing area of ​​the step using only the screw drive of a second adjusting component. This panel penetrates deep into the post-pouring strip and directly supports the concrete surface, thus avoiding the problem of the device being unable to enter due to the internal operating space being smaller than the outer opening. Furthermore, because the limiting panel provides direct internal support, the force transmission path is shortened, and the support rigidity is improved. This effectively suppresses formwork displacement and wall bulging during concrete pouring, while also avoiding large-scale chiseling and repair later. Simultaneously, by creating strip-shaped holes in the frame bars of the main frame and using multiple first adjusting components, the adjustable panel can freely translate and lock along the length and width directions within the adjustment space enclosed by the main frame. Operators can flexibly adjust the planar position of the adjustable panel to accurately locate the anchoring point of the limiting panel. Furthermore, since the limiting panel and the adjustable panel are detachably connected via a second adjusting component, they can be replaced according to the actual shape and size of different post-cast strips, thereby further improving the versatility and adaptability of the anchoring device to different working conditions. In addition, the entire anchoring device adopts a prefabricated adjustable structure, and all components can be disassembled and reused, which reduces material waste, lowers construction costs, and is easy to operate without the need for complex equipment.

[0018] The present invention proposes a method for anchoring post-cast strips. By using the above-mentioned adjustable anchoring device for post-cast strips, the movement of the limiting panel and the planar positioning of the adjustable panel can be completed simply by turning the adjusting component. The method is easy to operate, has high construction efficiency, and has good on-site practicality. Attached Figure Description

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1 to 3 This invention proposes an adjustable anchoring device for post-cast strips, comprising a main frame 1, an adjustable panel 2, multiple first adjustment components 3, a limiting panel 4, and at least three second adjustment components 5. The main frame 1 is a rectangular ring structure formed by four frame strips 11 connected end to end in sequence. Each frame strip 11 has a strip-shaped hole 110 extending along its length direction, and each strip-shaped hole 110 connects to the inner and outer sides of the main frame 1. The adjustable panel 2 is positionably disposed in the adjustment space enclosed by the main frame 1 along both the length and width directions of the main frame 1. The adjustable panel 2 has at least three threaded holes extending through it along its thickness direction. Furthermore, at least three threaded holes are arranged in a non-linear manner; multiple first adjustment components 3 correspond one-to-one with multiple strip holes 110, each first adjustment component 3 includes a first adjustment member 31 and a locking member 32, the first adjustment member 31 passes through the strip hole 110 and is connected to the corresponding frame strip 11, the locking member 32 is screwed to the first adjustment member 31 and abuts against the side of the frame strip 11 away from the adjustment space; the limiting panel 4 has at least three mounting holes through it along the thickness direction, the mounting holes correspond one-to-one with the threaded holes; at least three second adjustment members 5 are screwed one-to-one with the threaded holes and are rotatably connected to the limiting panel 4 through the corresponding mounting holes.

[0027] This invention, by fixing the larger main frame 1 to the outer opening of the post-pouring strip 100, utilizes only the spiral drive of the second adjusting component 5 to independently drive the smaller limiting panel 4 through the narrowed area of ​​the step, penetrating deep into the post-pouring strip 100 and directly supporting the concrete bearing surface. This avoids the problem of the device being unable to enter due to the internal operating space being smaller than the outer opening. Furthermore, since the limiting panel 4 achieves direct internal support, the force transmission path is shortened, and the support rigidity is improved, effectively suppressing formwork displacement and wall bulging during concrete pouring, while also avoiding large-area chiseling and repair later. Simultaneously, by opening strip holes 110 on the frame strips 11 of the main frame 1, and cooperating with multiple first adjusting components 3, the adjustable panel 2 can freely translate and lock along the length and width directions within the adjustment space enclosed by the main frame 1. Operators can flexibly adjust the planar position of the adjustable panel 2, thereby accurately positioning the anchoring point of the limiting panel 4. Furthermore, since the limiting panel 4 and the adjustable panel are detachably connected via the second adjusting component 5, they can be replaced according to the actual shape and size of different post-cast strips 100, thereby further improving the versatility and adaptability of the anchoring device to different working conditions. In addition, the entire anchoring device adopts a prefabricated adjustable structure, and all components can be disassembled and reused, which reduces material waste, lowers construction costs, and is easy to operate without the need for complex equipment.

[0028] In this embodiment, the adjustable anchoring device includes four second adjusting members 5. The adjustable panel 2 is rectangular and has threaded holes at the four corners. The four second adjusting members 5 are screwed into the threaded holes at the four corners in a one-to-one correspondence and are rotatably connected to the four corner areas of the limiting panel 4 respectively.

[0029] In other embodiments, the adjustable anchoring device is not limited to four second adjusting members 5. Three, five or more second adjusting members 5 may be provided according to the shape, size and force requirements of the limiting panel 4. No specific limitation is made here.

[0030] Specifically, such as Figure 1 As shown, the adjustable panel 2 has a rectangular plate structure, and the outer contour of the adjustable panel 2 is proportionally reduced in both length and width directions to the inner cavity contour enclosed by the four frame strips 11 of the main frame 1. This proportional reduction allows the adjustable panel 2 to be naturally inserted into the inner cavity of the main frame 1 without the need for additional guide alignment, thus reducing installation difficulty. Secondly, the geometric similarity ensures that the gap between the adjustable panel 2 and the frame strips 11 is uniform and controllable, avoiding skewness and jamming, and ensuring smooth plane adjustment and positioning accuracy.

[0031] In this embodiment, the limiting panel 4 is also a rectangular plate structure, and its length and width are both smaller than those of the adjustable panel 2.

[0032] More specifically, the maximum vertical distance between the outer surfaces of each side of the adjustable panel 2 and the inner surfaces of the corresponding frame strips 11 is 50mm-150mm. This range provides a flexible adjustment margin, which can cover different dimensional deviation requirements from small and medium-sized structures to ultra-long structures with post-cast strips 100. The lower limit of 50mm ensures the compactness of the device and avoids excessive redundancy of the main frame 1, which would increase material costs. The upper limit of 150mm meets the larger positioning adjustment requirements in large-scale projects.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, the frame strip 11 has at least two strip holes 110 spaced apart along its length, and the first adjustment component 3 is arranged in a one-to-one correspondence with the strip holes 110.

[0034] In practical use, operators can increase the number of strip holes 110 and the first adjusting component 3 according to actual needs, thereby enabling the configurability of the anchoring stiffness and enhancing the adaptability of the device to different working conditions. For example, in this embodiment, three strip holes 110 are provided at intervals on both long frame bars 11, and two strip holes 110 are provided at intervals on both short frame bars 11.

[0035] Specifically, a bearing is fixedly mounted on the limiting panel 4, and the inner ring of the bearing is interference-fitted with the second adjusting member 5. This interference fit eliminates relative looseness and axial movement between the second adjusting member 5 and the limiting panel 4, ensuring that when the second adjusting member 5 is rotated, the limiting panel 4 can move precisely and stably along the thickness direction without delay or wobbling, thus improving the accuracy and reliability of the position adjustment of the limiting panel 4. Secondly, the bearing converts the sliding friction between the second adjusting member 5 and the limiting panel 4 into rolling friction, reducing turning resistance and making operation more effortless and smoother.

[0036] Specifically, a screw head is provided at the end of the second adjusting member 5 furthest from the limiting panel 4; the screw head is not shown in the figure. By providing the screw head, operators can directly screw the second adjusting member 5 by hand or with a regular wrench without the need for special tools, reducing the difficulty of construction operations and improving adjustment efficiency. At the same time, the screw head provides a larger torque transmission area, making the rotation of the second adjusting member 5 smoother and less strenuous.

[0037] In this embodiment, the diameter of the second adjusting member 5 is larger than that of the first adjusting member 31.

[0038] Specifically, the four corners of the main frame 1 are each welded from two adjacent frame strips 11, and each corner has a reinforcing corner plate on its outer side. The reinforcing corner plate is welded to the corresponding two frame strips 11. The reinforcing corner plate is not shown in the figure. The reinforcing corner plate is located on the outer side of the corner, which facilitates welding construction and makes it easier to ensure the quality of the weld. At the same time, the outer corner plate can effectively resist the external tensile stress on the corner of the frame strip 11 during the concrete pouring process, preventing the corner from opening or plastic deformation, thereby ensuring the overall rigidity and dimensional stability of the main frame 1. Secondly, the outer arrangement completely avoids the internal cavity space of the main frame 1, ensuring that the adjustment range of the adjustable panel 2 in the length and width directions is not interfered with, making full use of the internal volume of the main frame 1.

[0039] Specifically, the main frame 1 is made of steel. Steel has high strength and modulus of elasticity, which can withstand the lateral pressure, buoyancy and temperature stress generated during the pouring of the post-cast strip 100 concrete, ensuring that the main frame 1 is not prone to plastic deformation during repeated use, thereby maintaining the accuracy of the planar positioning reference of the adjustable panel 2.

[0040] Furthermore, the steel surface can be treated with rust prevention, such as galvanizing or epoxy resin spraying, to resist the alkaline environment in concrete and the humid conditions at the construction site, thereby extending the service life and reuse count of the equipment.

[0041] The present invention also proposes an anchoring method based on the location of the post-cast strip, using the aforementioned adjustable anchoring device for the post-cast strip, comprising the following steps: S1. Fix the main frame 1 to the walls on both sides of the post-pouring strip 100 so that the adjustment space enclosed by the main frame 1 corresponds to the area of ​​the post-pouring strip 100 to be poured.

[0042] By pre-fixing the main frame 1 at the designed position of the outer opening of the post-pouring strip 100, the relative positioning benchmark between the entire anchoring device and the post-pouring strip 100 area is ensured to be accurate. The main frame 1 serves as the benchmark platform for all subsequent adjustment operations. The adjustment space enclosed by its rectangular ring structure corresponds to the area to be poured, providing ample space for the two-dimensional planar adjustment of the adjustable panel 2. This avoids repeated disassembly and assembly due to positioning deviations and improves construction efficiency.

[0043] Furthermore, in step S1, the main frame 1 is fixed to the walls on both sides of the post-cast strip 100 by tie bolts. The tie bolts apply clamping force from both sides simultaneously, ensuring that the main frame 1 is subjected to symmetrical and uniform force, thus improving the overall stability of the anchoring device. Moreover, the tie bolt connection method allows for convenient assembly and disassembly; once the concrete has reached its strength, the main frame 1 can be removed simply by loosening the nuts, without damaging the existing walls, facilitating reuse of the device. In addition, the tie bolts provide sufficient tensile bearing capacity, effectively resisting the lateral pressure transmitted to the main frame 1 during concrete pouring through the limiting panel 4, the second adjusting component 5, and the adjustable panel 2, ensuring the rigidity and reliability of the anchoring system throughout the entire pouring process.

[0044] S2. Rotate each of the second adjusting parts 5 to drive the limiting panel 4 to move relative to the adjustable panel 2 along the thickness direction until the limiting panel 4 reaches the preset limiting working surface position.

[0045] The operator uses a wrench or directly by hand to turn the screw head at the end of the second adjusting component 5, causing the second adjusting component 5 to rotate and move axially in the threaded hole of the adjustable panel 2. Since the second adjusting component 5 is rotatably connected to the limiting panel 4 through a bearing, the limiting panel 4 will not rotate with it when it is turned, but will only move in the thickness direction.

[0046] S3. Adjust the position of the adjustable panel 2 in the length and width directions within the main frame 1 using the first adjustment component 3, and then tighten the locking component 32 to fix the adjustable panel 2 relative to the main frame 1.

[0047] The operator observes the alignment of the limiting panel 4 with the force-bearing surface. If a deviation is found between the length or width of the limiting panel 4 and the target anchor point, the locking parts 32 are loosened, allowing the first adjusting part 31 to slide freely in the slot 110. The operator manually pushes the first adjusting part 31 to move the adjustable panel 2 along the length or width of the main frame 1 to the target position. After adjustment, the locking parts 32 are tightened, pressing against the side of the frame strip 11 away from the adjustment space, thereby fixing the adjustable panel 2 relative to the main frame 1, thus fixing the position of the limiting panel 4.

[0048] S4. Pour concrete in the post-pouring strip 100 area, using the limiting panel 4 as the limiting interface during pouring.

[0049] Following conventional concrete pouring procedures, concrete is poured in layers into the post-pouring strip 100 area and compacted using a vibrator. During the pouring process, the limiting panel 4, as part of the formwork system, directly bears the lateral pressure of the concrete. Due to its sufficient support rigidity, the limiting panel 4 will not move backward or shift, thus ensuring the accuracy of the post-pouring strip 100's forming dimensions.

[0050] S5. Once the concrete reaches the preset strength, rotate the second adjusting component 5 in the reverse direction to detach the limiting panel 4 from the concrete surface. Then, dismantle the main frame 1, adjustable panel 2, limiting panel 4, first adjusting component 3, and second adjusting component 5 as a whole. The design strength here refers to the minimum strength standard at which the concrete can withstand demolition stress without damage; the specific value can be determined according to design requirements.

[0051] The operator uses a wrench or directly by hand to turn the screw head at the end of the second adjusting component 5 in the opposite direction, causing the second adjusting component 5 to move the limiting panel 4 away from the concrete surface. After observing that a uniform gap appears between the limiting panel 4 and the concrete surface, it is confirmed that it has completely detached. Remove the fixed connection between the main frame 1 and the external structure, and move the main frame 1, adjustable panel 2, limiting panel 4, and all adjusting components out of the post-pouring strip 100 area as a whole. Clean and inspect each component after removal, and replace worn parts if necessary for future use.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
