Description

Technical Field

[0001] The utility model relates to the technical field of reinforcement equipment, in particular to a reinforcement device for large-section columns. Background Technique

[0002] Load-bearing columns mainly undertake the tasks of transmitting loads and supporting floors in building structures. They can transfer the loads on the floor slabs to the foundation to ensure the stability and safety of buildings. The design and selection of load-bearing columns need to be determined according to the load conditions and structural requirements of the floors to ensure that they can withstand sufficient pressure.

[0003] Load-bearing columns are mainly formed by pouring concrete. During construction, first, the steel reinforcement cage as the skeleton is tied, then the pouring formwork is made outside the steel reinforcement cage, and finally, concrete is filled into the pouring formwork. After the concrete is completely solidified, the pouring formwork can be removed. Before the concrete is poured, the pouring formwork needs to be reinforced to ensure the restraining ability of the pouring formwork on the concrete and make the concrete solidify stably. At present, the reinforcement of the formwork is mainly carried out through the cooperation of screws and fixing rods. This type of reinforcement method requires operators to alternately set two groups of fixing screws and fixing rods at the same position. This reinforcement method is cumbersome in use, so we propose a reinforcement device for large-section columns. Content of the Utility Model

Detailed implementation manners

[0024] The following further elaborates the present utility model in combination with the accompanying drawings and embodiments for the above and other technical features and advantages of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them.

[0025] Embodiment:

[0026] As Figures 1-5 shown, the present utility model provides a large-section column reinforcement device, which includes two groups of main clamping plates 1. Through holes are provided on the side surfaces of the two ends of the two groups of main clamping plates 1. A connecting and fixing rod 2 is installed between the ends of the two groups of main clamping plates 1 through the through holes. Jacks 3 are provided on the front surfaces of the two ends of the two groups of main clamping plates 1. The jacks 3 at one end of the two groups of main clamping plates 1 form a connection group. A group of side support rods 4 are provided in each of the two connection groups. Screw holes 5 are provided in the middle of the side support rods 4. A threaded push rod 6 is connected inside the screw holes 5. A side clamping plate member 7 is sleeved at the end of the threaded push rod 6;

[0027] The two groups of main clamping plates 1 form a clamping area in the horizontal axis direction under the restriction of the two groups of connecting and fixing rods 2. The side support rods 4 arranged between the main clamping plates 1 cooperate with the screw holes 5, the threaded push rods 6 and the side clamping plate members 7 to form a clamping area in the vertical axis direction.

[0028] The connecting and fixing rod 2 includes a connecting rod 21 and a fixed nut 22;

[0029] The connecting rod 21 is connected to the through holes on the side surfaces of the ends of the two groups of main clamping plates 1. There are two groups of fixing nuts 22, and the two groups of fixing nuts 22 are respectively threadedly connected to the two ends of the connecting rod 21. After the fixing nuts 22 are connected to the connecting rod 21, the fixing nuts 22 can play a role in clamping the formwork of the load-bearing column, so as to fix the formwork of the load-bearing column.

[0030] The connecting and fixing member 2 further includes a connecting gasket 23. The connecting gasket 23 is arranged between the fixing nut 22 and the main clamping plate 1. The connecting gasket 23 includes a gasket body 231 and a rubber gasket 232. The gasket body 231 and the rubber gasket 232 are adhesively connected. The rubber gasket 232 can deform after being compressed, and the deformed rubber gasket 232 can push the gasket body 231 in the reverse direction, so that the fixing nut 22 abutted against the gasket body 231 can maintain the meshing state with the connecting rod 21, thereby ensuring the connection stability between the fixing nut 22 and the connecting rod 21.

[0031] The jack 3 is designed as a square and penetrates the main clamping plate 1. The two ends of the side support rod 4 are matched with the jack 3. The two ends of the side support rod 4 are respectively nested in the jacks 3 opened at the ends of the two groups of main clamping plates 1. The side support rod 4 is restricted by the jack 3, and the side support rod 4 is used as the reverse support of the threaded push rod 6.

[0032] A number of groups of equally spaced jacks 3 are opened at both ends of the main clamping plate 1. The number of groups of jacks 3 opened at both ends of the two groups of main clamping plates 1 cooperate to form a number of connection groups. The number of connection groups can be used for the selection of the connection of the side support rod 4, so as to better adapt to the formwork of load-bearing columns with different lengths and widths, and reduce the adjustment stroke of the threaded push rod 6 provided on the side support rod 4.

[0033] The threaded push rod 6 includes a threaded rod 61, a rotating joint 62 and a connecting socket 63;

[0034] The threaded rod 61 is arranged inside the threaded hole 5 and is threadedly connected to the threaded hole 5. The rotating joint 62 is formed at the end of the threaded rod 61. The connecting socket 63 is sleeved on the other end of the threaded rod 61. The connecting socket 63 can rotate around the threaded rod 61 as the axis. When the side clamping plate member 7 is pushed by the threaded push rod 6 to connect the side clamping plate member 7 with the formwork of the load-bearing column, the rotating joint 62 drives the threaded rod 61 to rotate by connecting with an external wrench through the rotating joint 62. When the threaded rod 61 rotates, it can move horizontally along the threaded hole 5 through the threaded connection with the threaded hole 5. During the horizontal movement of the threaded rod 61, it is connected to the side clamping plate member 7 through the connecting socket 63 and pushes the side clamping plate member 7 until the side clamping plate member 7 contacts the formwork of the load-bearing column. The connecting socket 63 can rotate relative to the threaded rod 61 while maintaining contact with the side clamping plate member 7, so as to ensure the normal and smooth rotation of the threaded rod 61.

[0035] The side clamping plate member 7 includes a connecting sleeve 71 and a side clamping plate 72;

[0036] The connecting sleeve 71 is sleeved outside the connecting socket 63. The side clamping plate 72 is welded to the end of the connecting sleeve 71. The side clamping plate 72 is pushed by the threaded push rod 6. Under the push of the threaded push rod 6, the side clamping plate 72 can be connected to the formwork of the load-bearing column, playing a role in restricting and fixing the formwork of the load-bearing column.

[0037] The side clamping plate 72 is provided with several groups of different length specifications, and the lengths of the side clamping plates 72 of each specification increase in sequence. By setting the side clamping plates 72 with different lengths, the fixing of formworks of different specifications of load-bearing columns can be better adapted, improving the adaptability of the device;

[0038] A spring 8 is sleeved outside the side clamping plate 72. The two ends of the spring 8 are respectively connected to the side clamping plate 72 and the side support rod 4. Under the elastic force of the spring 8, the side clamping plate 72 can push the threaded push rod 6 in the reverse direction, so that a stressed state can be maintained between the threaded push rod 6 and the side clamping plate 72, avoiding loosening of the threaded push rod 6 due to vibration.

[0039] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
