Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

This embodiment provides a column formwork framework that can solve the problems that reinforced concrete frame structures exist among the prior art.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

Referring to fig. 1-5, an embodiment of the present invention provides a column formwork framework 1, which includes a plurality of long rods 101 extending uniformly and not coplanar. For example, if the pillar form 1 has a polygonal column configuration, each long rod 101 serves as a side edge of the pillar form 1. Each long rod 101 is fixedly connected through a fixing device, a clamping groove for placing the template 3 is formed between any two adjacent long rods 101, namely, a clamping groove for clamping the template 3 is formed on the side wall of any two adjacent long rods 101. One end of the column formwork framework 1 is used for being connected with the column positioning embedded part 6 or being connected with other column formwork frameworks 1.

Referring to fig. 4, the using steps of the column formwork framework 1 are as follows: according to the size requirement of a column in a building design drawing, a column formwork framework 1 is purchased or manufactured, then a column positioning embedded part 6 is pre-supported, a foundation 2 is poured, and then the column formwork framework 1 is in butt joint with the column positioning embedded part 6. The top of the column positioning embedded part 6 is provided with a through hole for connecting with the column formwork framework 1. All be provided with transition piece 7 between two arbitrary adjacent stock 101 in post formwork framework 1 bottom, the both ends of transition piece 7 respectively with two stock 101 fixed connection. The transition piece 7 is provided with through holes corresponding to the holes on the top surface of the post positioning embedded piece 6, the holes on each transition piece 7 are opposite to the holes on the top surface of the post positioning embedded piece 6, and then the transition pieces are fixed by fasteners. To facilitate screwing by the operator, the fastener may be a wing nut. Then, steel bar blanking is carried out in the column formwork framework 1. When carrying out the reinforcing bar unloading, column formwork skeleton 1 can play the effect of support and correction to the reinforcing bar, before not installing template 3, has sufficient space timing steel reinforcement cage and the interval between the column formwork skeleton 1, and timing work is simple and convenient, can improve work efficiency effectively. And after the blanking is finished, installing the template 3 in the clamping groove of the column formwork framework 1, and finally casting the column. For a building with multiple floors, the lower end of the upper-layer column formwork framework 1 is fixedly connected, for example welded, with the upper end of the lower-layer column formwork framework 1.

So set up, post formwork framework 1 both is the stitch that the building beautified, and the atress fulcrum that follow-up building decoration transformed again, and required parts such as decoration transformation all can be connected with stock 101 through bolt-up's mode or welded mode, and need not to plant the muscle or squeeze into expansion bolts to concrete main structure, can protect building main structure for decoration transformation work is simple and convenient implementation, thereby accelerates whole construction process. For example, the curtain wall keel 8 of the facade curtain wall 9 can be connected with the long rod 101 of the column formwork framework 1 in a welding mode, and then the facade curtain wall 9 is installed on the curtain wall keel 8 without planting bars or implanting expansion bolts on the concrete structure of the column, so that the construction speed is higher, and the concrete structure of the column cannot be damaged.

When carrying out the formwork to the post, template 3 can be installed in the draw-in groove between two stock 101, and the formwork system of post formwork skeleton 1 itself as the post promptly need not to use scaffold frame, square timber and metal fastener etc. to build extra braced system and come fixed die plate 3, saves artifical material, and building subject structure completion back, and post formwork skeleton 1 need not demolish as some of building, need demolish the work that could carry out next step with formwork braced system for among the prior art, use the utility model discloses a construction process can be optimized to post formwork skeleton 1 for the engineering progress.

Moreover, the long rod 101 and the reinforced concrete structure are mechanically supplemented to assist the concrete in supporting, so that the cross section size of the column can be effectively reduced compared with a single reinforced concrete building mode in the prior art, the size of the cross section of the column and the size of the template 3 are beneficial to being unified, the standardization and batch production of the template 3 are facilitated, the subsequent work load of cutting, supporting and removing the template is reduced, the material recovery and the repeated utilization rate are improved, and the project progress is accelerated

Finally, because the size of post formwork skeleton can be unified, thereby can the factory production also can indoor production, thereby the standardized production who matches with it all can be indoor going on, not restricted by weather factor, the work that originally can not develop in rainy day, like unwrapping wire, cutting die, reinforcing bar unloading can shift to indoor production, thereby accelerate the construction progress, and each kind of work process can the cross operation, reduce the risk of litter worker, thereby reduce the waste of manpower and financial resources. And the column formwork frameworks required by all floors can be produced together without being limited by the sequence of working procedures, and like an assembled steel structure, the column formwork frameworks can be produced in advance, so that the construction progress is accelerated.

In some embodiments, each long rod 101 is an angle steel (which may be a steel bar directly purchased from the market, or an angle steel made by welding or bending using a flat steel), a square steel, an angle aluminum, or a square aluminum.
