Description

Technical Field

[0001] The utility model relates to the field of engineering columns, in particular to a corrugated column template. Background Art

[0002] Construction site corrugated column formwork is mainly used for casting corrugated columns in building construction to ensure that their shape, size and strength meet the design requirements.

[0003] In the prior art, the construction site corrugated column formwork is usually made of corrugated steel plates. The corrugated steel plates can be semi-circular arc-shaped. A plurality of semi-circular arc-shaped corrugated steel plates are connected up and down to form a semi-cylindrical body. The two semi-cylindrical bodies are relatively formed into a cylindrical body. The inner diameter of the cylindrical body matches the diameter of the corrugated column.

[0004] The installation and disassembly of the corrugated column formwork usually adopts an integral assembly structure. Before the formwork is installed, it is necessary to first position it according to the construction drawings, and then assemble it according to the design requirements. During the installation process, attention should be paid to the verticality and horizontality of the formwork to ensure that the shape and size of the corrugated column meet the design requirements. When disassembling the formwork, it is necessary to follow the order of first removing the connecting bolts, then removing the slide rails, and finally removing the corrugated steel plate. At the same time, in order to ensure the long-term use of the corrugated column formwork, regular maintenance is required. Maintenance includes cleaning dust and stains on the surface of the formwork, checking the deformation and damage of the formwork, and replacing damaged parts in a timely manner. At the same time, attention should also be paid to the storage environment of the formwork to avoid damage caused by adverse factors such as direct sunlight and rain erosion.

[0005] The corrugated steel plates used in the prior art are very troublesome to install and disassemble. They need to be installed according to the drawings, and the weight of the corrugated steel plates is also heavy. The installation process of the construction workers is also very complicated and the installation and assembly are also very inconvenient. Moreover, the corrugated steel plates are prone to rust and corrosion when encountering rain during storage when not in use, which is not conducive to subsequent use and increases the cost of use. At the same time, the price of the corrugated steel plates is also high.

[0006] Therefore, it is particularly important to design a corrugated column formwork that can be quickly assembled without the need for setup, has low usage and operating costs, and has good resistance to the external environment. Utility Model Content

[0007] The present application provides a corrugated column formwork, which adopts the following technical solution:

[0008] A corrugated column template comprises a corrugated pipe made of plastic material. The corrugated pipe is elastic. At least one throat clamp is arranged on the corrugated pipe. The throat clamp consists of two semicircular iron blocks. The two iron blocks are fixedly connected by bolts and nuts. A steel bar passes through the middle of the corrugated pipe.

[0009] Optionally, four support columns are provided on the throat clamp at one-third of the corrugated pipe, and a rectangular support base is provided on the support columns.

[0010] Optionally, the entire material of the bellows is high-density polyethylene.

[0011] Optionally, the bellows has a length of 4-5 meters and an inner diameter of 70-80 centimeters.

[0012] Optionally, a grouting port is provided on the top of the corrugated pipe, and the diameter of the grouting port is 5-8 cm.

[0013] Optionally, the support column can be telescopically adjustable.

[0014] Optionally, an arc-shaped semicircle is provided on the inner side wall of the corrugated tube.

[0015] Optionally, a release coating is provided on the inner side wall of the corrugated tube.

[0016] Compared with the prior art, the beneficial effects of the utility model are: compared with the corrugated steel plate used in the prior art, the device is more convenient and quick to set up, and the materials used are also very simple compared with the corrugated steel plate. At the same time, the corrugated column template of the device is also very light and flexible compared with the corrugated steel plate. The corrugated pipe is used as the main body for grouting, and the inner side wall of the corrugated pipe is provided with an arc. After the pouring is completed, the overall structure of the column is completed. At the same time, the corrugated pipe can be used once or repeatedly. In terms of procurement cost, the use of the corrugated pipe is cheaper than the cost of the corrugated steel plate, which greatly reduces the construction cost. At the same time, the corrugated pipe is composed of high-density polyethylene, has strong stability and pressure resistance, and can withstand the pressure of concrete during pouring.

[0017] Corrugated steel plates need to be assembled and erected, and concrete leakage is prone to occur at the erection joints. The corrugated pipe is an integrated structure that avoids the connection process and reduces the possibility of leakage. The hose clamp is set on the corrugated pipe of the device to strengthen the reliability of the overall corrugated pipe, and the use and purchase cost of the corrugated pipe is also cheaper than that of the corrugated steel plate, reducing the cost.

[0029] An embodiment of the utility model provides a corrugated column template.

[0030] Example 1: Figure 1 As shown, the bellows 1 is vertically arranged on the ground, and a throat hoop 2 is arranged on the bottom of the bellows 1 for fixing. The throat hoop 2 is composed of two semicircular iron blocks, and the two throat hoop 2 are connected and fixed by bolts 4 and nuts 5. The throat hoop 2 is fixed at the bottom of the bellows 1 close to the ground.

[0031] Working principle: The construction workers first complete the erection of the overall steel reinforcement structure of the column. After the erection of the overall steel reinforcement structure of the column, the construction workers will put the corrugated pipe 1 into the overall steel reinforcement structure of the column. The inner side wall of the corrugated pipe 1 is provided with an arc-shaped semicircle. The throat clamp 2 is provided on the bottom of the corrugated pipe 1 to clamp the corrugated pipe 1, which can prevent the excessive pressure at the bottom during the pouring of the corrugated pipe 1, and the concrete will break the corrugated pipe 1 and cause cracks. The construction workers pour from the pouring port at the top of the corrugated pipe 1, loosen the bolts 4 and nuts 5 on the throat clamp 2, remove the throat clamp 2, tear open the corrugated pipe 1 to obtain the poured corrugated column, and the construction workers polish the corrugated column.

[0032] Example 2: Figure 2-6 As shown, a corrugated column template includes a corrugated pipe 1, which stands upright on the ground. A plurality of throat hoops 2 are arranged on the corrugated pipe 1. The length of the corrugated pipe 1 is 4-5 meters, and the inner diameter is 70-80 centimeters. A throat hoop 2 is arranged at one-third of the corrugated pipe 1. The throat hoop 2 is composed of two semicircular iron blocks. The two throat hoops 2 are connected and fixed by bolts 4 and nuts 5. Four support columns 3 are arranged around the throat hoop 2. The support columns 3 are obliquely arranged to support the throat hoop 2, and the support columns 3 are welded to the throat hoop 2. A rectangular support base 6 is arranged at the bottom of the support column 3. The arrangement of the support base 6 can enhance the overall support of the corrugated column template.

[0033] Working principle: The construction workers first complete the erection of the overall steel bar structure of the column. After the erection of the overall steel bar structure of the column, the construction workers will put the corrugated pipe 1 into the overall steel bar structure of the column. The side wall inside the corrugated pipe 1 is provided with an arc-shaped semicircle. The throat clamp 2 is provided on the bottom of the corrugated pipe 1 to clamp the corrugated pipe 1, which can prevent the concrete from being too high at the bottom during the pouring of the corrugated pipe 1 and causing cracks in the corrugated pipe 1. A throat clamp 2 with a support column 3 is provided at one-third of the corrugated pipe 1. The throat clamp 2 is connected and fixed by bolts 3 and nuts 4, and the support base 6 on the support column 3 is installed on the ground. At the same time, a throat clamp 2 is also provided on the upper side of the corrugated pipe 1, and a grouting port is provided at the bottom of the corrugated pipe 1. The diameter of the grouting port is 5-8 cm, so as to prevent the grouting speed from being too fast and causing excessive pressure on the side of the corrugated pipe 1 to cause rupture. After the pouring is completed, the hose clamp 2 is untied and the corrugated pipe 1 can be directly cut and pulled off. In this way, the entire corrugated column is poured. The next step is for the construction workers to grind, trim and paint the corrugated column after the pouring is completed.

[0034] The bellows 1 is made of high-density polyethylene as the whole material. The high-density polyethylene can make the bellows 1 have strong wear resistance and pressure resistance, withstand the transmission of high-pressure media, and is not easy to deform or break. At the same time, the bellows 1 has good aging resistance and is not affected by erosion such as rainwater. It will not crack or become brittle during use. The interval setting of the throat clamp 2 can effectively reinforce the whole bellows 1 to prevent rupture during pouring.

[0035] Embodiment 3: A demoulding coating is provided on the inner wall of the corrugated tube 1 to prevent the inside of the corrugated tube 1 from sticking to the concrete. The corrugated tube 1 can be demoulded very quickly after the concrete is poured and cooled, and the corrugated tube 1 can be used for the second time. Other features are the same as those of Embodiment 2.

[0036] Embodiment 4: The support column 3 is retractable, and the length of the support column 3 can be adjusted according to the height of the corrugated column template. Other features are consistent with those of Embodiment 2.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view. The scope of the present invention is defined by the appended claims, rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.
