Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and specifically relates to a novel reinforced concrete shaped beam. Background Art

[0002] With the continuous development of modern construction technology and the widespread application of new technologies, such as aluminum formwork and climbing frames, the shape of building facades tends to be more grid-like and unified, which makes construction easier and significantly improves production efficiency. However, this trend also brings some problems. The traditional construction of independent beams requires the erection of cantilever support frames, which has high investment costs, high operational risks, and slow construction progress. Changing independent beams to simple steel structure beams changes the initial mechanical design system of the design, which requires recalculation and design, and has high design costs. In addition, steel structure construction has high requirements for steel structure construction technology, pre-embedded and pre-set requirements, and high requirements for professional construction. When aluminum formwork and climbing frames are used on the construction site, it is not suitable to use full steel structure replacement. Summary of the invention

[0003] In order to solve the above problems, the utility model discloses a new type of reinforced concrete shaped beam, including a steel formwork and a shaped beam body. The steel formwork is arranged on the top of the shaped beam body. The shaped beam body is a supporting component with steel bars inside and cast with concrete. The shaped beam body is pre-embedded with bolts. The present application adopts reinforced concrete components as shaped beams, and combines the process of prefabricated steel formwork for construction. The prefabricated steel formwork has supporting capacity in the span direction, so the supporting structure in the middle part of the traditional formwork can be omitted, and support is only provided on both sides of the shaped beam, thereby improving construction efficiency and reducing costs. Compared with the traditional independent shaped beam construction method, this project adopts the construction method of steel component formwork + triangular support frame, which eliminates high-risk operations such as cantilever beams and formwork support frames, and does not affect the progress of the main construction, with good overall benefits.

[0004] In order to achieve the above object, the technical solution of the utility model is as follows:

[0005] A new reinforced concrete shaped beam comprises a steel formwork and a shaped beam body. The steel formwork is arranged on the top of the shaped beam body. The shaped beam body is a concrete supporting member with steel bars inside. The bottom of the supporting member is a first channel steel. The first channel steel is provided with through holes and pouring holes. Fixing bolts are arranged at the through holes of the first channel steel.

[0006] As an improvement of the utility model, the steel template includes a second channel steel and a patterned steel plate, and the patterned steel plate is welded to both sides of the channel steel.

[0007] As an improvement of the present utility model, the first channel steel and the second channel steel are 22a channel steels, and the thickness of the patterned steel plate is 3 mm.

[0008] As an improvement of the present invention, the fixing bolt is any one or more of a hexagonal bolt and an expansion bolt.

[0009] As an improvement of the present invention, the second channel steel is provided with a through hole, a hexagonal bolt is arranged at the through hole, an angle steel is arranged on the outer side of the channel steel, and the angle steel is fixedly connected to the shaping beam body by the hexagonal bolt.

[0011] The beneficial effects of the utility model are:

[0012] This application adopts the technology of prefabricated steel formwork to eliminate the support structure of the middle part of the traditional formwork, simplify the construction process and improve the construction efficiency. At the same time, it eliminates the high-cost and high-risk operations such as traditional cantilever frames and formwork support frames. The construction method of steel formwork and triangular support frames reduces the construction cost and reduces the safety hazards at the construction site.

[0018] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] As shown in the figure, a new type of reinforced concrete shaped beam described in the utility model includes a steel formwork and a shaped beam body. The steel formwork is arranged on the top of the shaped beam body. The shaped beam body is a concrete supporting member with steel bars inside. The bottom of the supporting member is a first channel steel. The first channel steel is provided with through holes and pouring holes. Fixing bolts are arranged at the through holes of the first channel steel.

[0020] The steel template of the utility model comprises a second channel steel and a patterned steel plate, and the patterned steel plate is welded to both sides of the channel steel.

[0021] The first channel steel and the second channel steel described in the utility model are 22a channel steels, and the thickness of the patterned steel plate is 3mm.

[0022] The fixing bolts described in the utility model are any one or more of hexagonal bolts and expansion bolts.

[0023] The second channel steel of the utility model is provided with a through hole, a hexagonal bolt is arranged at the through hole, an angle steel is arranged at the outer side of the channel steel, and the angle steel is fixedly connected with the shape beam body through the hexagonal bolt.

[0024] The modeling beam body of the utility model is movably connected with a triangular support through fixing bolts, the triangular support is located at both sides of the bottom of the first channel steel, and the fixing bolts are expansion bolts.

[0025] Specifically, the working principle of the utility model is as follows:

[0026] First, weld the steel formwork at the construction site. The steel formwork consists of channel steel and patterned steel plates. The second channel steel serves as the main structure, and the patterned steel plates are welded to both sides of the second channel steel. Through holes are opened on the channel steel, and pre-prepared hexagonal bolts are inserted into them. These bolts will be used to connect the steel formwork and the main body of the shaped beam, as well as for subsequent fixing. Leakage-proof measures can be taken at the through holes to prevent the subsequent pouring of concrete from leaking out of the formwork.

[0027] Next, after the steel formwork is installed, the angle steel is fixed to the ceiling where the shaped beam is to be set, the steel formwork is connected and fixed by hexagonal bolts, and then the supporting components are welded. First, the supporting steel bars are welded into the steel formwork, and then the first slot plate is welded, and then the concrete is poured. The concrete fills the space inside the shaped beam body through the pouring holes, and combines with the pre-buried fixing bolts to form an overall supporting structure.

[0028] When the concrete is fully solidified, the triangular supports are installed. These supports are located on both sides of the bottom of the shaped beam body and are fixed and connected by pre-buried fixing bolts. The function of the triangular supports is to enhance the stability and bearing capacity of the shaped beam. After inspection and confirmation, the construction is completed. The connection between the steel formwork and the shaped beam body is connected by bolts, which allows a certain degree of flexibility between the components and ensures the stability and reliability of the structure.

[0029] The entire workflow realizes the manufacture and installation of new reinforced concrete beams through the coordination of steel formwork, embedded bolts, concrete pouring and triangular supports. This working principle ensures the stability, bearing capacity and high efficiency of the structure.
