Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for supporting a column formwork. Background Art

[0002] In civil engineering, formwork is a model of the outer panel of a structure made before concrete is poured, so that the concrete can solidify into the designed structure within the panel.

[0003] Currently, when a template is manufactured, a fixing component is usually required to fix the template into shape.

[0004] However, when fixing the column formwork, the formwork fixing assembly in the prior art often causes the formwork to be concave due to the need to ensure the four corners of the column, resulting in the need for secondary repairs after the column is formed. Therefore, the utility model proposes a device for supporting the column formwork to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a device for supporting column formwork to solve the problem that the formwork fixing assembly in the prior art proposed in the above background technology often causes the formwork to be concave when fixing the column formwork due to the need to ensure the four corners of the column, resulting in the need for secondary repair after the column is formed.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a device for a top support column formwork, the device for the top support column formwork comprising:

[0007] An installation threaded rod, one side of the installation threaded rod is threadedly sleeved with a No. 1 threaded barrel, one end of the installation threaded rod is rotatably connected to a plurality of support plates distributed in a circular array, a spring is fixedly connected between the support plate and the installation threaded rod, one side of the No. 1 threaded barrel is slidably connected to a plurality of slide bars corresponding to the positions of the support plates, one side of the slide bar is fixedly connected to a baffle rod for supporting the support plate, the outer side of the No. 1 threaded barrel is threadedly sleeved with a No. 2 threaded barrel for supporting and driving the baffle rod to slide, and the baffle rod and the No. 2 threaded barrel are rotatably clamped.

[0008] Preferably, one end of the mounting threaded rod is fixedly connected to a regular polygonal mounting block, and the spring is located between the regular polygonal mounting block and the support plate.

[0026] See also Figures 1 to 6 , the utility model provides a technical solution:

[0027] Embodiment 1, a device for supporting column formwork, the device for supporting column formwork comprises: installing threaded rod 1.

[0028] Specifically, a No. 1 threaded tube 2 is threadedly sleeved on one side of the installation threaded rod 1, and one end of the installation threaded rod 1 is rotatably connected to a plurality of support plates 3 distributed in a circular array, a spring 4 is fixedly connected between the support plate 3 and the installation threaded rod 1, a plurality of slide bars 6 corresponding to the positions of the support plates 3 are slidably connected to one side of the No. 1 threaded tube 2, and a stopper 8 for supporting the support plate 3 is fixedly connected to one side of the slide bar 6, and a No. 2 threaded tube 5 for supporting and driving the stopper 8 to slide is threadedly sleeved on the outer side of the No. 1 threaded tube 2, and a No. 2 threaded tube 5 for supporting and driving the stopper 8 to slide is rotatably engaged with the stopper 8 and the No. 2 threaded tube 5. After being fixed on the outer side of the template, the device is first inserted into the inner side of the template, and then the template is fixed according to the template. The plate size is adjusted by rotating the No. 1 threaded cylinder 2 to initially install the device on the inner side. During the rotation of the No. 1 threaded cylinder 2, the restraint on the support plate 3 will be released, so that the support plate 3 will open under the action of the spring 4. The opened support plate 3 can better support the formwork, which can make it easier for the device to pass through the steel frame. Then, the No. 2 threaded cylinder 5 is rotated. When the No. 2 threaded cylinder 5 rotates, it will push the blocking rod 8 to slide toward the end of the support plate 3, thereby providing support for the opened support plate 3. Then, the No. 1 threaded cylinder 2 and the No. 2 threaded cylinder 5 are rotated according to the degree of support, so that the device is firmly installed on the inner side of the formwork and supports the middle part of the formwork.

[0029] In order to facilitate the contraction of the support plate 3, one end of the installation threaded rod 1 of the present application is fixedly connected to a regular polygonal mounting block 11, and the spring 4 is located between the regular polygonal mounting block 11 and the support plate 3, so that the support plate 3 can be given a contraction space, which is convenient for the subsequent passage of the device through the steel frame.

[0030] In order to rotatably install the support plate 3, a plurality of protruding plates 12 are fixedly connected to the side of the regular polygonal mounting block 11 of the present application, a fixed shaft rod 13 is fixedly connected between two protruding plates 12 on the same plane, a shaft sleeve 31 is rotatably connected to one side of the fixed shaft rod 13, and the shaft sleeve 31 and the support plate 3 are fixedly connected, so that a plurality of support plates 3 can be rotatably installed on each surface of the spring 4, thereby facilitating the contraction of the support plates 3.

[0031] In order to improve the supporting effect of the baffle rod 8 on the support plate 3, a plurality of limiting grooves 32 distributed in a linear array are opened on one side of the support plate 3 of the present application, and a convex strip 9 adapted to the limiting groove 32 is fixedly connected to one side of the baffle rod 8. Through the clamping connection between the convex strip 9 and the limiting groove 32, the baffle rod 8 can be further restricted from expanding outward, thereby improving the supporting effect of the baffle rod 8 on the support plate 3.

[0032] In order to facilitate the sliding installation of the slide bar 6, the slide bar 6 of the present application is set to a "T" shape, and a plurality of slide grooves 21 for the No. 1 threaded tube 2 to slide are opened on one side of the No. 1 threaded tube 2, so as to ensure the sliding of the slide bar 6 on the No. 1 threaded tube 2 and ensure that the slide bar 6 will not tilt.

[0033] To facilitate the installation of the baffle rod 8, one end of the slide bar 6 of the present application is fixedly connected to a mounting plate 7, the mounting plate 7 and the baffle rod 8 are fixedly connected and one side of the mounting plate 7 is fixedly connected to a connecting plate 71, one side of the connecting plate 71 is fixedly connected to a positioning plate 72 rotatably connected to the No. 2 threaded tube 5, and one side of the No. 2 threaded tube 5 is provided with a card slot 51 for installing the positioning plate 72. The mounting plate 7 can provide installation space for the baffle rod 8, and through the cooperation of the connecting plate 71, the positioning plate 72 and the card slot 51, it can not only ensure that the No. 2 threaded tube 5 can push the baffle rod 8 to slide toward the end of the support plate 3 when sliding, but also prevent the baffle rod 8 and the slide bar 6 from sliding out of the No. 1 threaded tube 2 when the support plate 3 is contracted.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
