Description

Technical Field

[0001] This utility model relates to the field of construction formwork reinforcement technology, specifically a modular reinforcement device for concrete column formwork. Background Technology

[0002] With the rapid development of the social economy, in the process of building construction, the traditional reinforcement method for supporting concrete column formwork is to erect a steel pipe scaffolding support system and a temporary reinforcement system on the outside of the formwork to prevent concrete from bulging, running out of formwork and leakage of grout after the top formwork is completed. This reinforcement method is wasteful of human resources and turnover resources because of the large amount of labor and turnover materials required and the slow turnover speed.

[0003] In current construction projects, aluminum alloy combined steel formwork is commonly used for concrete column support. The uppermost aluminum alloy combined steel formwork has aluminum alloy templates around its perimeter. To enhance the overall stability of the concrete column formwork, tension rings are typically fitted onto round steel pipes, with both ends of the pipes resting on the aluminum alloy templates around the upper formwork. However, during actual construction, the height of the aluminum alloy templates constantly changes, causing the tension rings on the round steel pipes to move up and down. This often results in excessively large distances between the tension rings, leading to dispersed stress on the aluminum templates and affecting concrete quality. In practice, the tension rings are often divided into two parts for clamping. This results in an approximately elliptical shape during clamping, creating gaps between the tension rings and the template, hindering proper fixation. Therefore, current fixation methods require further improvement.

[0004] Therefore, there is an urgent need to invent a modular reinforcement device for concrete column formwork. Summary of the Invention

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a modular reinforcement device for concrete column formwork to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a modular reinforcement device for concrete column formwork, comprising several tension rings, wherein multiple positioning holes are equidistantly provided on the outer wall of the tension rings, and the tension rings located in the upper and lower spatial positions are connected to each other by positioning rods, wherein the positioning rods are divided into positioning screws, limiting nuts and sleeves, one end of the positioning screw is sleeved in the positioning hole, the other end of the positioning screw is sleeved in the sleeve, the limiting nut is sleeved on the positioning screw to support the end of the sleeve, the length of the positioning screw sleeved in the sleeve is adjusted by the limiting nut, and the end of the tension ring is provided with a support, and the two ends are closed by adjusting screws and nuts.

[0007] Preferably, the sleeve is a hollow cylindrical structure with openings at both ends, and both the inner and outer walls of the sleeve are smooth. The diameter of the inner wall of the sleeve is equal to the diameter of the positioning screw.

[0008] Preferably, the limiting nut has handles symmetrically provided at both ends of its outer side wall.

[0009] Preferably, a spherical pad is provided in the positioning hole to adjust the misalignment distance of the positioning holes of the upper and lower tensioning rings.

[0010] Preferably, the inner wall of the positioning hole is provided with a thread that matches the positioning screw.

[0011] Preferably, the nut is provided with a spherical washer and a slanted washer on the side near the support to adjust the misalignment angle.

[0012] Preferably, a triangular reinforcing rib is provided between the side wall of the support and the clamp wall.

[0013] Preferably, the support has a connecting hole in the central area, and the adjusting screw is inserted into the connecting holes at both ends of the tension ring for connection, and the tightness is adjusted by the nuts at both ends.

[0014] Preferably, the tensioning ring has a wedge-shaped interface at its open end, with the left and right ends fitting together through a wedge-shaped surface, and the tensioning ring is made of a flexible material.

[0015] Preferably, the sleeve is available in various lengths for adjustment and replacement.

[0016] The present invention has the following beneficial effects:

[0017] 1. This utility model is composed of a tensioning ring and a positioning rod. When fixing the template, depending on the space width of the column, when encountering columns of different heights, simply adjusting the screw length of the positioning screw in the sleeve can adjust and fix the template, increasing the template's stability.

[0018] In the connection process of the reinforcement device, the tension ring contacts the template surface. When encountering different column diameters, the tension ring is sleeved on the template and connected by adjusting screws at both ends and nuts. By tightening the nuts, the tension ring is adjusted to the appropriate position to fix the template.

[0019] 3. In the process of connecting the reinforcement device, the positioning rod connects the tensioning rings in the upper and lower spaces. At the same time, the positioning rod makes the force between each group of tensioning rings more uniform, thereby increasing the interaction force between each tensioning ring and further supporting the template. The positioning rod and the tensioning ring together reinforce the column, increasing the firmness and resistance of the column template.

[0020] 4. This utility model is easy to disassemble, making it convenient for workers to transport and handle, thus increasing its practicality;

[0021] 5. In this utility model, a spherical washer is provided in the positioning hole to adjust the misalignment distance between the positioning holes of the upper and lower tension rings, and the inner wall of the positioning hole is provided with a thread that matches the positioning screw to enhance the firmness of the tension ring.

[0022] 6. In this utility model, triangular reinforcing ribs are provided between the side wall of the support and the clamp wall, which can increase the stress strength of the tension ring and the support and reduce the risk of failure under stress load. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] See Figure 1 and Figure 4 A modular reinforcement device for concrete column formwork is shown in the figure. Multiple positioning holes 3 are equidistantly arranged on the outer wall of the tensioning ring 1. The tensioning ring 1 is connected at upper and lower spatial positions by positioning rods 2. The positioning rods 2 consist of a positioning screw 201, a limiting nut 202, and a sleeve 203. One end of the positioning screw 201 is fitted into the positioning hole 3, and the other end is fitted into the sleeve 203. The limiting nut 202 is fitted onto the positioning screw 201 to support the end of the sleeve 203. The length of the positioning screw 201 fitted into the sleeve 203 is adjusted by the limiting nut 202. The tensioning ring 1 has multiple positioning holes 3 equidistantly arranged on its outer wall. Multiple positioning holes 3 are provided. Tensioning rings 1 at the upper and lower spatial positions are connected by positioning rods 2. The positioning rods 2 are divided into positioning screws 201, limiting nuts 202 and sleeves 203. One end of the positioning screws 201 is fitted into the positioning holes 3, and the other end of the positioning screws 201 is fitted into the sleeves 203. The limiting nuts 202 are fitted onto the positioning screws 201 to support the end of the sleeves 203. The length of the positioning screws 201 fitted into the sleeves 203 is adjusted by the limiting nuts 202.

[0029] Angle steel is welded to the outer surface of the clamp ring, and several positioning holes 3 are equidistantly arranged on the angle steel for fixed connection with the clamp ring at the upper and lower positions. Tensioning rings 1 are fitted at the upper and lower positions. Tensioning rings 1 can be made of flexible steel and are connected by positioning rods 2. The sleeve 203 of the positioning rod 2 is a hollow cylindrical structure with open ends, and both the inner and outer walls of the sleeve 203 are smooth.

[0030] The positioning screw 201 is inserted into the positioning hole 3 of the tension ring 1 and sleeved on the outer wall of the tension ring 1. The upper and lower positioning screws 201 are respectively sleeved in different tension rings 1. The positioning screw 201 cooperates with the sleeve 203. The limiting nut 202 is sleeved on the positioning screw 201 to support the sleeve 203. The insertion depth of the positioning screw 201 on the sleeve 203 is adjusted by the limiting nut 202, thereby controlling the stability between the tension rings 1 to improve the overall integrity.

[0031] The sleeve 203 is a hollow cylindrical structure with openings at both ends. Both the inner and outer walls of the sleeve 203 are smooth. The inner diameter of the sleeve 203 is equal to the diameter of the positioning screw 201.

[0032] The device has a modular structure. It uses sleeves 203 of different positions, quantities and specifications from top to bottom, and then inserts positioning screws 201. The distance between the upper and lower tensioning rings is controlled by the insertion depth of the sleeves 203. The device can be flexibly adjusted according to the actual construction conditions and is applicable to cement columns of various cross-sectional sizes, with wide applicability.

[0033] Specifically, the limiting nut 202 has handles symmetrically provided at both ends of its outer side wall. The sleeve 203 fitted on the positioning screw 201 is adjusted by the limiting nut 202 to adjust the relative position of the sleeve 203 with the positioning screw 201, thereby adjusting the distance between the tension rings 1. The limiting nut 202 has handles symmetrically provided at both ends, which facilitates quick adjustment and fixing.

[0034] Specifically, the tensioning ring 1 has connecting holes at both ends through supports. Adjusting screws 4 and corresponding nuts 6 are inserted into the connecting holes. Through cooperation, the nuts 6 at both ends control the tightness of the overall tensioning ring 1 through the adjusting screws 4.

[0038] Specifically, the nut 6 is provided with a spherical washer 7 and an inclined washer 8 on the side near the support 5 to adjust the misalignment angle. The spherical washer 7 and the inclined washer 8 are used to eliminate the force change caused by the misalignment of the tension ring 1 in the upper and lower spaces.

[0039] The working principle of this utility model is as follows:

[0040] In use, first, place the bottom tension ring 1 around the template. Adjust the tightness of the tension ring 1 by using the adjusting screw 4 and nut 6. Screw the positioning screw 201 into the positioning hole 3. Then, screw the limiting nut 202 into the positioning screw 201 at a suitable height above the positioning hole 3. Next, put the sleeve 203 onto the positioning screw 201, with the lower end of the sleeve 203 reaching the limiting nut 202. Then, place the tension ring 1 around the template to a tightness that allows it to be pulled up and down. Then, screw the limiting nut 202 into the positioning screw 201 at a suitable height below the positioning hole 3. The positioning screw 201 extends into the sleeve 203 and falls to the limiting nut 202. Finally, tighten the tension ring 1. At this point, the tension rings at the top and bottom positions have been installed. Repeat the above installation steps to achieve modular reinforcement of the concrete column template.
