Description

Technical Field

[0001] This utility model relates to the field of column reinforcement technology, and more specifically, to an adjustable combined wooden formwork for reinforcing columns without dismantling the wall. Background Technology

[0002] In the field of building reinforcement construction, reinforcing existing building structures is an important and complex task. Currently, the process of expanding the cross-section of columns to reinforce existing walls requires first demolishing the existing walls, then reinforcing the columns, and finally rebuilding the walls. This process of demolition and rebuilding requires significant manpower, material resources, and financial investment, greatly increasing construction costs. Furthermore, the rebuilt walls and reinforced columns are made of different materials, and due to differences in shrinkage rates and expansion coefficients, cracks are easily generated between them during subsequent use. This not only affects the aesthetics of the building structure but also seriously threatens its stability and safety. The series of procedures involving demolition, reinforcement, and rebuilding is cumbersome and time-consuming, resulting in a long construction period. In addition, the demolition of existing walls may cause unnecessary damage to other parts of the building structure, further affecting the overall performance of the building. Moreover, the disposal of construction waste after demolition is a challenging issue, increasing environmental pressure and generating additional processing costs. Therefore, we propose an adjustable combined wooden formwork for reinforcing columns without demolishing walls. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an adjustable and combined wooden formwork for reinforcing columns without dismantling the wall. This solves the technical problem that the current method of expanding the cross-section of reinforcing columns in existing walls requires the first demolition of the existing wall, which has many problems.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable combined wooden formwork for reinforcing columns without dismantling walls, comprising an original wall, an original column, an L-shaped wooden formwork, a fixing mechanism set on the L-shaped wooden formwork, and a connecting mechanism set on the fixing mechanism. The original column is located between the original walls. The L-shaped wooden formwork has four arrays set on the outside of the original column, and both ends of the L-shaped wooden formwork are attached to the original wall. A first square timber is set on the outer surface of the L-shaped wooden formwork at the contact position with the original wall. A second square timber is symmetrically set on the outer surface of the L-shaped wooden formwork outside the first square timber. A first steel pipe is horizontally set on the outer side of the L-shaped wooden formwork. A longitudinal tie rod and a transverse tie rod are respectively set between the L-shaped wooden formwork. A second steel pipe is symmetrically set on both sides of the longitudinal tie rod and the transverse tie rod on the outer side of the first steel pipe. A fixing plate connected to the longitudinal tie rod and the transverse tie rod is installed on the outer side of the first steel pipe and the second steel pipe. The connecting mechanism includes an upper collar and a lower collar.

[0005] Preferably, the original wall has holes adapted to the first steel pipe, the transverse tie rod and the longitudinal tie rod, and the first steel pipe, the transverse tie rod and the longitudinal tie rod all pass through the original wall through the corresponding holes.

[0006] Preferably, the longitudinal tie rods and the transverse tie rods are arranged alternately, and both the longitudinal tie rods and the transverse tie rods pass through the first steel pipe and the second square timber.

[0007] Preferably, the fixing plate includes mounting portions installed at both ends of the transverse tie rod and the longitudinal tie rod, with first positioning portions symmetrically arranged at both ends of the mounting portions. The first positioning portions are arc-shaped and wrapped around the second steel pipe.

[0008] Preferably, the end of the first positioning part is bent at ninety degrees to provide a second positioning part, the second positioning part is arc-shaped, and the second positioning part is wrapped around the first steel pipe.

[0009] Preferably, the upper collar is fitted onto the upper first steel pipe, and the lower collar is fitted onto the lower first steel pipe. The lower end of the upper collar is provided with an upper connecting plate, and the upper end of the lower collar is provided with a lower connecting plate. The upper connecting plate and the lower connecting plate are connected by bolts and nuts. The front end of the upper connecting plate is provided with a stepped groove, and the front end of the lower connecting plate is provided with a stepped protrusion adapted to the stepped groove. The stepped protrusion is engaged in the stepped groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the design of an L-shaped wooden formwork structure, allows the L-shaped wooden formwork to fit the structural layout of the original columns and walls. In actual construction, construction workers do not need to carry out complex demolition or modification of the original walls. They only need to place four L-shaped wooden formworks adjacent to each other on the outside of the original columns to construct the pouring space for the reinforced columns. This construction method greatly reduces obstacles and interference in the construction process, lowers the construction difficulty, and improves construction efficiency. Compared with traditional construction methods, it reduces the generation of construction waste, saves the material procurement costs and labor costs required for demolishing and rebuilding walls, directly reduces construction costs, and avoids the hidden danger of cracks caused by the combination of different materials in the reconstruction of walls and columns. It solves many problems existing in the current method of expanding the cross-section of reinforced columns in existing walls, which requires the demolition of the existing walls first.

[0012] 2. This utility model also incorporates a fixed plate structure. The fixed plate includes mounting portions installed at both ends of the transverse and longitudinal tie rods. The first positioning portion, symmetrically arranged at both ends, is arc-shaped and can tightly wrap around the second steel pipe. The second positioning portion, formed by bending the end of the first positioning portion at ninety degrees, is arc-shaped and can wrap around the first steel pipe. This wrapping design allows the first and second steel pipes to be tightly connected together. Through its connection with the longitudinal and transverse tie rods, the fixed plate evenly transmits the tension of the tie rods to the first and second steel pipes, making the tie rods, steel pipes, and templates form a cohesive whole. The tie rods provide tension, and the fixed plate distributes the tension to the steel pipes, which in turn acts on the template, ensuring that the template is subjected to uniform force in all directions. This prevents deformation or bulging of the template due to uneven force, enhances the stability of the entire fixing mechanism, and ensures that the steel pipes will not shift or loosen during concrete pouring, thereby ensuring that the template system can effectively withstand the lateral pressure of the concrete.

[0013] 3. This utility model also designs an upper connecting plate and a lower connecting plate structure. The upper and lower collars of the upper and lower connecting plates are respectively fitted onto the first steel pipes located above and below. The first steel pipes at different heights are tightly connected into a whole by bolts and nuts between the upper and lower connecting plates. The stepped structure at the front end of the upper and lower connecting plates is connected, which increases the positioning area of ​​the upper and lower connecting plates and improves the stability of the connection between the upper and lower connecting plates. This greatly enhances the stability of the entire formwork system in the vertical direction, so that when the formwork is subjected to the lateral pressure and impact force generated during concrete pouring, each part can work together to resist the external force, reduce the possibility of local deformation, and ensure the pouring quality of the reinforced column.

[0023] like Figures 1 to 8As shown, this utility model relates to an adjustable combined wooden formwork for reinforcing columns without dismantling walls, including an existing wall 101, an existing column 102, an L-shaped wooden formwork 103, a fixing mechanism 200 mounted on the L-shaped wooden formwork 103, and a connecting mechanism 300 mounted on the fixing mechanism 200. The existing column 102 is located between the existing walls 101. The L-shaped wooden formwork 103 has four arrays arranged on the outside of the existing column 102, and both ends of the L-shaped wooden formwork 103 are attached to the existing wall 101. A first square timber 201 is provided on the outer surface of the L-shaped wooden formwork 103 at the contact position with the existing wall 101. A second square timber 202 is symmetrically arranged on the outer side of the first square timber 201. A first steel pipe 205 is horizontally arranged on the outer side of the L-shaped wooden template 103. A longitudinal tie rod 203 and a transverse tie rod 204 are respectively arranged between the opposing L-shaped wooden templates 103. A second steel pipe 206 is symmetrically arranged on both sides of the longitudinal tie rod 203 and the transverse tie rod 204 on the outer side of the first steel pipe 205. A fixing plate 207 connected to the longitudinal tie rod 203 and the transverse tie rod 204 is installed on the outer side of the first steel pipe 205 and the second steel pipe 206. The connecting mechanism 300 includes an upper collar 301 and a lower collar 302. In actual construction, the present invention eliminates the need for construction workers to perform complex demolition or modification of the original wall 101. They only need to place four L-shaped wooden templates 103 adjacent to each other on the outside of the original column 102 to construct the pouring space for the reinforced column. This reduces the generation of construction waste and saves on material procurement costs and labor costs required for demolishing and rebuilding the wall, directly reducing construction costs. It also avoids the potential for cracks caused by the combination of different materials in the reconstructed wall and column.

[0024] Specifically, the existing wall 101 has holes adapted to the first steel pipe 205, the horizontal tie rod 204, and the vertical tie rod 203. The first steel pipe 205, the horizontal tie rod 204, and the vertical tie rod 203 all pass through the existing wall 101 through the corresponding holes. The horizontal tie rod 204 and the vertical tie rod 203 can be used for the initial positioning of the L-shaped wooden formwork 103.

[0025] Furthermore, the longitudinal tie rods 203 and the transverse tie rods 204 are staggered vertically, and both the longitudinal tie rods 203 and the transverse tie rods 204 pass through the first steel pipe 205 and the second square timber 202. The second square timber 202 can apply pressure to fix the L-shaped wooden formwork 103, and the first steel pipe 205 can apply pressure to the first square timber 201 and the second square timber 202, thereby fixing the L-shaped wooden formwork 103.

[0026] It is worth noting that the fixing plate 207 includes mounting portions 2071 installed at both ends of the transverse tie rod 204 and the longitudinal tie rod 203. First positioning portions 2072 are symmetrically arranged at both ends of the mounting portions 2071. The first positioning portions 2072 are arc-shaped and wrap around the second steel pipe 206. The arc-shaped first positioning portions 2072 of the fixing plate 207 can tightly wrap around the second steel pipe 206, allowing the second steel pipe 206 to be tightly installed on the outside of the square timber.

[0027] It is worth mentioning that the end of the first positioning part 2072 is bent at ninety degrees to provide a second positioning part 2073. The second positioning part 2073 is arc-shaped and wraps around the first steel pipe 205. The arc-shaped design of the second positioning part 2073 allows the first steel pipe 205 and the second steel pipe 206 to be tightly connected together. The fixing plate 207, through its connection with the longitudinal tie rod 203 and the transverse tie rod 204, evenly transmits the tension of the screw to the first steel pipe 205 and the second steel pipe 206, so that the screw, the steel pipe and the template form a coordinated whole. The screw provides the tension, and the fixing plate 207 distributes the tension to the steel pipe, which in turn acts on the template.

[0028] It is worth noting that the upper collar 301 is fitted onto the upper first steel pipe 205, and the lower collar 302 is fitted onto the lower first steel pipe 205. The lower end of the upper collar 301 is provided with an upper connecting plate 303, and the upper end of the lower collar 302 is provided with a lower connecting plate 304. The upper connecting plate 303 and the lower connecting plate 304 are connected by bolts and nuts. The front end of the upper connecting plate 303 is provided with a stepped groove 305, and the front end of the lower connecting plate 304 is provided with a stepped protrusion 306 that matches the stepped groove 305. The stepped protrusion 306 is engaged in the stepped groove 305. The upper collar 301 and lower collar 302 of the upper connecting plate 303 and the lower connecting plate 304 are respectively fitted onto the first steel pipe 205 located above and below, tightly connecting the first steel pipe 205 at different height positions into a whole. The stepped structure of the front end of the upper connecting plate 303 and the lower connecting plate 304 is connected, which increases the positioning area of ​​the upper connecting plate 303 and the lower connecting plate 304, improves the stability of the connection between the upper connecting plate 303 and the lower connecting plate 304, and greatly enhances the stability of the entire template system in the vertical direction.

[0029] Working Principle: This embodiment provides an adjustable combined wooden formwork for reinforcing columns without dismantling the wall. In use, four L-shaped wooden formwork panels 103 are first placed adjacent to each other between the existing wall 101. A first square timber 201, a second square timber 202, and a first steel pipe 205 are then installed. Next, longitudinal tie rods 203 and transverse tie rods 204 are installed, allowing them to pass through the second square timber 202 and the first steel pipe 205. Four L-shaped wooden templates 103 can be initially positioned. Then, a second steel pipe 206 is set outside the first steel pipe 205, with the second steel pipe 206 positioned on both sides of the longitudinal tie rod 203 and the transverse tie rod 204. Next, fixing plates 207 are installed at both ends of the longitudinal tie rod 203 and the transverse tie rod 204, so that the fixing plates 207 wrap around the first steel pipe 205 and the second steel pipe 206. Nuts are then installed at both ends of the longitudinal tie rod 203 and the transverse tie rod 204 and tightened. Steel pipe 205 can press the first square timber 201 and the second square timber 202 onto the outer surface of the L-shaped wooden formwork 103 for secondary fixation. The first square timber 201 can vertically reinforce the contact position between the L-shaped wooden formwork 103 and the original wall 101. The second steel pipe 206 can press the first steel pipe 205 onto the outer surface of the first square timber 201 and the second square timber 202 for tertiary fixation of the L-shaped wooden formwork 103. Finally, the connecting mechanism 300 is installed. During installation, the upper collar 301 is placed on the uppermost first square timber 201. On a steel pipe 205, a lower collar 302 is fitted onto the first steel pipe 205 located below, and the upper collar 301 and the lower collar 302 are brought close to each other, so that the upper connecting plate 303 and the lower connecting plate 304 are fitted together and fixed with bolts and nuts. The stepped protrusion 306 can be engaged in the stepped groove 305 to position the upper connecting plate 303 and the lower connecting plate 304. The connecting mechanism 300 can connect the first steel pipes 205 to each other, thereby fixing the L-shaped wooden formwork 103 four times to ensure the stability of the wooden formwork installation.
