Large circular concrete foundation pouring structure

Abstract

The utility model discloses a large circular concrete foundation pouring structure. The structure comprises an inner formwork; the outer formworks and the inner formworks are distributed at intervals, and a large circular concrete foundation is poured in the interval space between the inner formworks and the outer formworks; a formwork hoop ring is arranged outside the outer formwork, and the formwork hoop ring holds the outer portion of the outer formwork to hoop the outer portion of the outer formwork. Due to the fact that the multiple sets of formwork hoops which are vertically distributed at intervals are arranged outside the outer formwork for hooping, the situation that an inclined support is arranged outside the outer formwork on the ground is avoided, and the problem that the space from the ground to the outside of the outer formwork is occupied due to the fact that the inclined support can support the outside of the outer formwork by taking the ground as a foundation for stress is solved.

Description

Technical Field

[0001] The utility model relates to a large circular concrete foundation casting structure, belonging to the technical field of foundation casting. Background Art

[0002] For circular structures such as desulfurization towers or chimney towers, the bottom portion of the structure that contacts the ground is a large circular concrete foundation. When pouring on the ground, the inner and outer formwork must be erected first, then supported and stabilized to create a gap between the inner and outer formwork for subsequent pouring.

[0003] Existing external formwork supports are mostly inclined supports based on the external ground, see Chinese patent publication number CN113445538B. Although the inclined supports are based on the ground and can support the outside of the external formwork, the inclined supports will occupy the space from the ground to the outside of the external formwork. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a large circular concrete foundation casting structure.

[0005] The utility model is achieved through the following technical solutions.

[0006] The utility model provides a large circular concrete foundation casting structure, comprising:

[0007] Internal template;

[0008] The outer formwork is spaced apart from the inner formwork, and a large circular concrete foundation is poured into the space between the inner and outer formwork;

[0009] A template hoop is provided on the outside of the outer template, and the template hoop embraces the outside of the outer template to tighten it.

[0010] The interior of the inner template is supported by an oblique support, one end of the oblique support is supported on the ground, and the other end of the oblique support supports the inner surface of the inner template.

[0011] The template hoop has an end portion A and an end portion B which are spaced apart from each other in an upper and lower direction. The end portion A and the end portion B penetrate through the connecting welding plate and are welded and fixed thereto.

[0012] The connecting welding plate is provided with corresponding through holes for the end portion A and the end portion B to pass through.

[0013] The end portion A and the end portion B extend through the connecting welding plate; the end portion A extending from the connecting welding plate is fixedly connected to a pull rope A, and the pull rope A is fixedly connected to a retractable telescopic part A.

[0014] The end portion B extending out of the connecting welding plate is fixedly connected to a drawstring B, and the drawstring B is fixedly connected to a retractable telescopic member B.

[0015] The template hoops can be multiple groups vertically spaced and distributed outside the outer template.

[0016] A plurality of spaced-apart backboard wood planks are installed between the template hoop and the outer template.

[0017] The beneficial effect of the present invention is that since the outside of the outer formwork is surrounded and tightened by multiple groups of vertically spaced formwork hoops, the use of inclined supports on the ground on the outside of the outer formwork is avoided, and the problem that the inclined supports are based on the ground to support the outside of the outer formwork and thus occupy the space from the ground to the outside of the outer formwork is solved.

[0021] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0022] like Figures 1 to 2 shown.

[0023] A large circular concrete foundation casting structure of the present application comprises:

[0024] The inner formwork 1 and the outer formwork 2 are distributed at intervals, and a large circular concrete foundation (not shown in the figure) is poured into the interval 3 between the inner formwork 1 and the outer formwork 2.

[0025] The interior of the inner formwork 1 is supported by an inclined support 11 , one end of the inclined support 11 is supported on the ground 4 , and the other end of the inclined support 11 supports the inner surface of the inner formwork 1 .

[0026] The outer portion of the outer template 2 is provided with a template hoop 21 , which hugs the outer portion of the outer template 2 and tightens it.

[0027] The template hoop 21 has an end portion A22 and an end portion B23 that are spaced apart from each other. The end portions A22 and B23 pass through the connecting welding plate 24 and are welded to it. The connecting welding plate 24 is correspondingly provided with through holes for the end portions A22 and B23 to pass through.

[0028] The end portions A22 and B23 extend through the connecting weld plate 24; the end portion A22 extending through the connecting weld plate 24 is fixedly connected to a pull rope A26, which is fixedly connected to a retractable telescopic member A28; the end portion B23 extending through the connecting weld plate 24 is fixedly connected to a pull rope B25, which is fixedly connected to a retractable telescopic member B27. When the end portions A22 and B23 extend through the connecting weld plate 24 but are not welded, the retractable members A28 and B27 are fixed on the construction ground and are not moved. After the end portions A22 and B23 are pulled through the connecting weld plate 24 and extended and held, the pulled end portions A22 and B23 are welded to the connecting weld plate 24 to form a formwork hoop 21. The formwork hoop 21 can be a plurality of groups vertically spaced and distributed outside the outer formwork 2, but only one group is shown in the figure.

[0029] Since there are multiple groups of vertically spaced template hoops 21 on the outside of the outer template 2 to hold it tight, the use of inclined supports on the ground on the outside of the outer template 2 is avoided, and the problem that the inclined supports are based on the ground to support the outside of the outer template and thus occupy the space from the ground to the outside of the outer template is solved.

[0030] A plurality of spaced-apart backboard timbers 5 are installed between the template hoop 21 and the outer template 2 . Only four backboard timbers 5 are shown in the figure, and the actual number of backboard timbers 5 is determined according to the construction situation.
