Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, and more specifically, to a construction method for installing and reinforcing right-angled trapezoidal column formwork. Background Technology

[0002] As a type of irregular column, right-angled trapezoidal columns are typically installed on-site using flexible wooden formwork, taking cost into consideration. Due to the unique structure of right-angled trapezoidal columns, the traditional method for installing and reinforcing the formwork employs a "tie rod + double steel pipe" reinforcement method. Steel pipes are used to encircle the column as the main back brace. When encountering the sloping corners of the right-angled trapezoidal column, tie rods are used for reinforcement and tightening. The construction process is as follows: Column axis position measurement and layout → Right-angled trapezoidal column formwork cutting → Installation of column axis position positioning plate → Column formwork installation → Installation of secondary back brace (100×50mm timber) → Installation of diagonal braces → Installation of main back brace (φ48×3.0mm double steel pipe) → Tightening of φ14 tie rods → Right-angled trapezoidal column verticality correction → Inspection and acceptance.

[0003] However, the above technical solution has the following defects: when pouring concrete, under the lateral pressure generated by the concrete, the tie rod will slip outwards on the inclined side, resulting in a deviation in the cross-sectional dimensions of the right trapezoidal column concrete structure, which affects the quality and appearance of the concrete structure and the uniformity of the subsequent plaster thickness. In addition, for cases with large deviations in cross-sectional dimensions, other quality remedial technical measures need to be adopted later, which increases construction costs and construction period. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a construction method for reinforcing right-angled trapezoidal column formwork installation, which can greatly improve the stability and construction efficiency of right-angled trapezoidal column formwork installation, reduce construction costs, and has good market application prospects.

[0005] To achieve this objective, the present invention adopts the following technical solution: This invention provides a method for installing and reinforcing right-angled trapezoidal column formwork, comprising the following steps: S1. Based on the structural measurement and layout position, mark the axis and control line of the right trapezoidal column on the structural ground; S2. Make a right-angled trapezoidal column template and install it on the ground; S3. Install wooden beams on the back of the right-angled trapezoidal column formwork; S4. Install the main back rib irregular-shaped fastener on the outside of the right-angled trapezoidal column formwork; S5. Pass the tie rod through the main back rib irregular clip and the right-angle trapezoidal column template in sequence, and then set butterfly buckles at both ends of the tie rod and fix them with nuts; S6. After calibrating the verticality of the right-angled trapezoidal column and passing the inspection, pour concrete.

[0006] In a preferred embodiment of the present invention, the right-angled trapezoidal column template is composed of an upper base template, a straight waist template, a lower base template, and an inclined waist template spliced ​​together end to end. When making the right-angled trapezoidal column template, the upper base template, the lower base template, and the inclined waist template should be cut with a 45° chamfer.

[0007] In a preferred embodiment of the present invention, both the upper bottom template and the lower bottom template are provided with through holes for the tie rod to pass through.

[0008] In a preferred embodiment of the present invention, the main back rib irregular-shaped card is assembled from a first card plate, a second card plate, a third card plate, and a fourth card plate. Each of the first, second, and third card plates is provided with a rectangular card hole. The head of each of the first, second, and third card plates is provided with a fixing plate, and both the fixing plate and the fourth card plate are inserted into the rectangular card holes. The fixing plate is provided with a first fixing hole, and each of the first, second, third, and fourth card plates is provided with a second fixing hole. A galvanized pin is inserted into both the first and second fixing holes.

[0009] In a preferred embodiment of the present invention, the second fixing holes are provided in two rows, with two or more second fixing holes in each row, and the positions of the two rows of second fixing holes are staggered.

[0010] In a preferred embodiment of the present invention, a PVC pipe is sleeved on the tie rod.

[0011] The beneficial effects of this invention are as follows: The proposed construction method for installing and reinforcing right-angle trapezoidal column formwork utilizes a main back rib irregular-shaped fastener installed on the outside of the formwork. This ensures that the cross-sectional dimensions of the formwork will not exceed specifications or bulge under the lateral pressure generated during concrete pouring. Simultaneously, the tie rods secure the main back rib irregular-shaped fastener, making the overall installation and reinforcement of the right-angle trapezoidal column formwork more stable. This guarantees the construction quality and appearance of the right-angle trapezoidal column concrete structure, thus achieving significant advantages in construction efficiency, quality, and cost reduction in right-angle trapezoidal column formwork installation technology.

[0021] like Figures 1-15 As shown in the embodiment, a construction method for installing and reinforcing right-angled trapezoidal column formwork is provided, including the following steps: S1. Based on the structural measurement and layout position, mark the axis and control line of the right trapezoidal column on the structural ground; S2. Install a positioning plate at the axis, make a right-angled trapezoidal column template 1 and install it on the ground; S3. Install wooden beams 2 on the back of the right-angled trapezoidal column template 1. The wooden beams 2 are arranged vertically and serve as secondary back beams to support the outer side of the right-angled trapezoidal column template 1. S4. Install the main back rib irregular clamp 3 on the outside of the right-angle trapezoidal column formwork 1 to reinforce and support the right-angle trapezoidal column formwork 1, and prevent the right-angle trapezoidal column formwork 1 from bulging or deviation of cross-sectional dimensions due to the lateral pressure generated during concrete pouring; the timber 2 is located between the right-angle trapezoidal column formwork 1 and the main back rib irregular clamp 3, and the timber 2 and the main back rib irregular clamp 3 are in abutting fit; S5. Pass the tie rod 4 through the main back rib irregular clip 3 and the right-angle trapezoidal column template 1 in sequence. Then, set the butterfly buckle 5 at both ends of the tie rod 4 and fix it with the nut 6. The butterfly buckle 5 abuts against the outer side of the main back rib irregular clip 3, thereby fixing the main back rib irregular clip 3 and the right-angle trapezoidal column template 1 into one piece. S6. After calibrating the verticality of the right-angled trapezoidal column and passing the acceptance test, pour concrete to obtain the right-angled trapezoidal column concrete. After the concrete has solidified, remove the tie rod 4, the main back rib irregular clip 3, the timber 2, the right-angled trapezoidal column template 1 and the position positioning plate in sequence, and then cure the right-angled trapezoidal column concrete.

[0022] Specifically, such as Figure 1 As shown, the right-angled trapezoidal column template 1 is composed of an upper bottom template 11, a straight waist template 12, a lower bottom template 13, and a sloping waist template 14 spliced ​​together end to end. When making the right-angled trapezoidal column template 1, the upper bottom template 11, the lower bottom template 13, and the sloping waist template 14 should be cut with a 45° chamfer.

[0023] In this embodiment, the right-angled trapezoidal column has an upper base dimension of 400mm, a lower base dimension of 800mm, a sloping waist dimension of 566mm, a straight waist dimension of 400mm, and a column height of 3000mm. The upper base template 11, straight waist template 12, lower base template 13, and sloping waist template 14 are all made of 18mm thick film board. The timber beam 2 has a cross-sectional dimension of 100×50mm and a length of 2800mm. A 45° chamfer is cut at the contact point of the upper base template 11, lower base template 13, and sloping waist template 14 to ensure that the assembled right-angled trapezoidal column template 1 has a regular shape.

[0024] Specifically, both the upper bottom template 11 and the lower bottom template 13 have through holes for the tie rod 4 to pass through.

[0025] In this embodiment, after the right-angled trapezoidal column template 1 and the main back rib irregular-shaped fastener 3 are installed, one end of the tie rod 4 is sequentially passed through the rectangular locking hole 36 on the first locking plate 31, the through hole on the upper bottom template 11, the through hole on the lower bottom template 13, and the rectangular locking hole 36 on the third locking plate 33. The butterfly buckle 5 is located at both ends of the tie rod 4 and abuts against the first locking plate 31 and the third locking plate 33 respectively under the action of the nut 6, thereby fixing the right-angled trapezoidal column template 1 and the main back rib irregular-shaped fastener 3.

[0026] Specifically, such as Figures 1-14 As shown, the main back rib irregular-shaped clip 3 is assembled from a first clip plate 31, a second clip plate 32, a third clip plate 33, and a fourth clip plate 34. Each of the first clip plate 31, the second clip plate 32, and the third clip plate 33 is provided with a rectangular clip hole 36. Each of the first clip plate 31, the second clip plate 32, and the third clip plate 33 is provided with a fixing plate 35 at its head. Both the fixing plate 35 and the fourth clip plate 34 are inserted into the rectangular clip hole 36. The fixing plate 35 is provided with a first fixing hole 37. Each of the first clip plate 31, the second clip plate 32, the third clip plate 33, and the fourth clip plate 34 is provided with a second fixing hole 38. Galvanized pins 39 are inserted into both the first fixing hole 37 and the second fixing hole 38.

[0027] In this embodiment, the first clamping plate 31 is aligned with the upper bottom template 11 and is made of BH-shaped steel with a length of 1600mm, a width of 90mm, and a height of 36mm. The second clamping plate 32 is aligned with the straight waist template 12 and is made of DH-shaped steel with a length of 900mm, a width of 90mm, and a height of 36mm. The third clamping plate 33 is aligned with the lower bottom template 13 and is made of AH-shaped steel with a length of 1700mm, a width of 90mm, and a height of 36mm. The fourth clamping plate 34 is aligned with the inclined waist template 14 and is made of I-shaped steel with a length of 1500mm, a width of 90mm, a wing plate height of 15mm, and a web thickness of 8mm. The rectangular clamping hole 36 has a width of 20mm, and the steel plates on both the upper and lower sides of the rectangular clamping hole 36 are 8mm thick. The fixing plate 35 is made of steel with a length of 150mm, a width of 70mm, and a thickness of 16mm. A first fixing hole 37 is made at a starting point 30mm from left to right and 32mm from top to bottom on the fixing plate 35. The first fixing hole 37 has a length of 40mm and a width of 6mm. A second fixing hole 38 has a length of 40mm and a width of 6mm. The galvanized pin 39 is also a right-angled trapezoidal structure and is made of thick galvanized material with an upper base of 40mm, a lower base of 5mm, a straight waist of 150mm, an inclined waist of 154mm, and a thickness of 5mm. When assembling the main back rib irregular clamp 3, insert the fixing plate 35 at the head of the first clamp 31 into the rectangular clamping hole 36 of the second clamp 32, insert the fixing plate 35 at the head of the second clamp 32 into the rectangular clamping hole 36 of the third clamp 33, and insert both ends of the fourth clamp 34 into the rectangular clamping holes 36 of the first clamp 31 and the third clamp 33 respectively. During the assembly process, ensure that the first clamp 31, the second clamp 32, the third clamp 33 and the fourth clamp 34 abut against the timber 2. Then, insert the galvanized pin 39 into the first fixing hole 37 and the second fixing hole 38 to fix the relative positions of the first clamp 31, the second clamp 32, the third clamp 33 and the fourth clamp 34. This will result in the right-angled trapezoidal main back rib irregular clamp 3, and ensure that the cross-sectional dimensions of the right-angled trapezoidal column formwork 1 will not exceed the specification deviation or bulge under the lateral pressure generated by the pouring of concrete.

[0028] Specifically, such as Figures 1-14 As shown, the second fixing holes 38 are provided in two rows, with more than two second fixing holes 38 in each row, and the positions of the two rows of second fixing holes 38 are staggered.

[0029] In this embodiment, a first row of second fixing holes 38 are formed at starting points 58mm from left to right and 22mm from top to bottom on the first card plate 31, second card plate 32, third card plate 33, and fourth card plate 34. A second row of second fixing holes 38 are formed at starting points 28mm from left to right and 62mm from top to bottom on the first card plate 31, second card plate 32, third card plate 33, and fourth card plate 34. Each row of second fixing holes 38 is formed at 20mm intervals. The two rows of second fixing holes 38 are staggered and fixed by inserting galvanized pins 39 into the second fixing holes 38, which can meet the fixed support of right-angled trapezoidal columns with different cross-sectional dimensions.

[0030] Specifically, such as Figure 15 As shown, a PVC pipe 7 is fitted onto the tie rod 4.

[0031] In this embodiment, the PVC pipe 7 is a φ16 sleeve, which is mainly used to wrap the part of the tie rod 4 located inside the right-angled trapezoidal column template 1 to prevent the concrete from submerging and solidifying the tie rod 4 during pouring, thus making demolding difficult.

[0032] Furthermore, all components used in this embodiment are commercially available.

[0033] This invention has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. This invention is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims are also within the protection scope of this invention.
