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. 1-6, a beam formwork framework 1 according to an embodiment of the present invention includes a plurality of long rods 101 extending uniformly and not coplanar. For example, if the beam formwork framework 1 has a polygonal prism configuration, each long rod 101 serves as a side edge of the beam formwork framework 1, and the beam formwork framework 1 may have a quadrangular prism configuration with reference to fig. 1. Each long rod 101 is fixedly connected through a fixing device, and a clamping groove for placing the template 3 is formed between two side walls of any two adjacent long rods 101. Two ends of the beam formwork framework 1 are respectively used for being connected with different column formwork frameworks 8.

Referring to fig. 3, the using steps of the beam formwork framework 1 are as follows: according to the dimensional requirement of the roof beam in the architectural design drawing, purchase or make roof beam formwork skeleton 1, then dock roof beam formwork skeleton 1 with post formwork skeleton 8 (before here, post formwork skeleton 8 has carried out preliminary fixed connection with post location embedded part), and carry out preliminary fixed through metal fastener and fastener, adjust behind the position angle relation of roof beam formwork skeleton 1 and post formwork skeleton 8 and weld the two, then metal fastener can dismantle to get off and accomodate the arrangement so that utilize next time. And then, steel bar blanking is carried out on the beam formwork framework 1, namely, the steel bars are arranged in the beam formwork framework, and the steel bars extend towards the length direction of the beam formwork framework. When carrying out the reinforcing bar unloading, beam formwork skeleton 1 can play the effect of support and correction to the reinforcing bar, before the erection template, has the interval between sufficient space timing steel reinforcement cage and the beam formwork skeleton, and timing work is simple and convenient, can improve work efficiency effectively. And after the steel bar is blanked, installing the template 3 in the clamping groove of the beam formwork framework 1, and finally casting the beam. The beam formwork framework is fixedly connected with the concrete, and the template 3 can be detached for recycling.

So set up, beam formwork skeleton 1 both is the line foot 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 of the outer vertical face curtain wall can be connected with the long rod 101 of the beam formwork framework 1 in a welding mode, then the outer vertical face curtain wall is installed on the curtain wall keel, no steel bars are required to be planted on the concrete structure of the beam or expansion bolts are required to be planted, the construction speed is higher, and the concrete structure of the beam cannot be damaged; alternatively, the support rods of some ventilation pipes may be welded to the beam formwork framework to support the ventilation pipes.
