Technical Field

The invention belongs to the technical field of constructional column structures, and particularly relates to a formwork-free constructional column structure.

Background

The existing constructional columns are formed by erecting templates and pouring concrete on two sides of a wall body after the wall body is built. When the formworks of the constructional columns are erected, the formworks are arranged on the two sides of the wall respectively, so that the formworks are difficult to reinforce and inconvenient to operate. In addition, when the constructional columns of the outer vertical walls of some buildings are supported, the templates positioned on the wall body and facing the outer side of the building are more difficult to arrange, and meanwhile, the dangerous accidents that the templates fall off easily occur during the template removal. Therefore, it is necessary to design a construction column without supporting a formwork.

Disclosure of Invention

The invention aims to provide a formwork-supporting-free constructional column structure, which aims to solve the problem that a constructional column formwork in the prior art is inconvenient to support.

In order to achieve the purpose, the basic scheme of the invention provides a formwork-free constructional column structure which comprises a prefabricated rectangular hollow column body, wherein the column body comprises a steel reinforcement framework and a concrete part wrapped on the steel reinforcement framework, the steel reinforcement framework comprises longitudinal steel bars and a plurality of stirrups uniformly distributed along the length direction of the longitudinal steel bars, and the longitudinal steel bars and the stirrups form a cylindrical structure; the bilateral symmetry of cylinder is provided with serrated racking, serrated racking and concrete portion integrated into one piece, is provided with the through-hole that is used for wearing to establish the wall muscle on the serrated racking.

The principle and the beneficial effect of the basic scheme are as follows: the column body of the prefabricated rectangular hollow shape is arranged, the column body is arranged at the position of the constructional column arranged on the wall body, and the concrete is filled by utilizing the hollow part of the column body, so that a template is not required to be arranged when the constructional column is formed. The steel reinforcement framework is arranged, and the concrete part is supported by the steel reinforcement framework, so that the structural strength of the concrete part is improved, and the concrete part is prevented from being damaged when the column is carried; meanwhile, after the steel reinforcement framework is arranged in the column body, the steel reinforcement framework does not need to be arranged again during installation of the constructional column, and operation burden caused by independent installation of the steel reinforcement framework is reduced. And a serrated racking is arranged to increase the connection strength of the constructional column and the wall body.

By arranging the hollow column body with the steel reinforcement framework and utilizing the prefabricated concrete part on the column body to surround the concrete for later-stage pouring of the constructional column, a template is not required to be arranged when the constructional column is formed in the wall body, and the workload caused by erecting and disassembling the template is saved; especially, when the constructional column at the edge of the building is formed, the accident potential of template falling caused by erecting the template is avoided.

Further, the cylinder includes first column section and second column section, and the upper end of first column section can be dismantled with the lower extreme of second column section and be connected. After the cylinders are arranged into two sections which are detachably connected, the cylinders can be installed in a segmented mode, so that the problem that the installation and operation are difficult due to the fact that the weight of the cylinders is too large when the whole cylinders are installed at one time is solved, and the installation and operation of the cylinders are facilitated.

Furthermore, the longitudinal steel bars of the first column section are connected with the longitudinal steel bars of the second column section through threaded sleeves. The longitudinal reinforcing steel bars of the two column sections are connected by the threaded sleeves, so that the longitudinal reinforcing steel bars of the whole column body form a whole, and meanwhile, the threaded sleeves are convenient to connect and operate when being connected.

Further, the top of the second column section is provided with a feeding notch communicated with the inside of the second column section. Set up the feeding breach, the concrete that conveniently pours the later stage from feeding breach department fills into the cylinder inside, causes the damage to the second post section when avoiding the later stage to set up the feed inlet to the second post section.

Further, the through-hole is along the vertical bar hole that extends. The through hole is formed into the strip-shaped hole, so that the wall pulling rib can also pass through the through hole under the condition of having the hook, the hook of the wall pulling rib can be manufactured at one time, the wall pulling rib and the constructional column are not required to be connected and then manufactured, and the constructional column is convenient to use.

Further, concrete portion is fretwork form towards one side of serrated racking. After the concrete part is hollowed out, the weight of the concrete part can be reduced, so that the overall weight of the column body is reduced, and the installation and operation are convenient; meanwhile, the hollow positions on the concrete part are opposite to the wall body, the hollow positions are sealed by the wall body, and the effect of the connection strength between the concrete of the constructional column and the wall body can be enhanced.

Further, one side of the serrated racking facing the column body is provided with a vertical groove. After the groove is formed, the weight of the prefabricated part of the serrated racking can be reduced, the weight of the prefabricated part of the whole constructional column is further reduced, and the installation difficulty of the column body is reduced.

Furthermore, a plurality of vibrating holes are formed in the side wall of the concrete part parallel to the plane of the wall body, and hole plugs are connected in the vibrating holes in a sealing mode. Set up the hole of vibrating, the inside that the device of conveniently using vibrates from the hole department of vibrating and stretches into the cylinder vibrates the concrete that the later stage was pour, improves the quality of pouring of concrete.

Furthermore, the hole plug is an elastic hole plug, a jack is axially arranged on the hole plug, one end, facing the inside of the column body, of the jack is fixedly connected with a conical elastic sealing ring, and the smaller end of the elastic sealing ring faces the inside of the column body. Set up jack and elastic sealing ring, utilize the elastic sealing ring to carry out the shutoff to the jack to avoid the concrete to flow from the jack, simultaneously, the existence of sealing ring also can not influence the effect of vibrating of the inside of the device of vibrating and stretching into the cylinder to the concrete.

Further, the elastic sealing ring and the hole plug are integrally formed. The mode of adopting integrated into one piece makes things convenient for the preparation of elastic sealing ring and stopple, also can improve the connection effect of elastic sealing ring and stopple simultaneously.
