Description

A kind of extension component for supporting rod of sliding platform

Technical Field

The utility model relates to the technical field of construction equipment, in particular to an extension component used for a support rod of a sliding formwork platform.

Background Art

Slipform construction is a commonly used construction method in construction projects. Its characteristic is that during the concrete pouring process, a special formwork structure is used. By constantly moving the formwork, the concrete can be poured continuously and form an overall structure. This construction method can improve the construction efficiency of the project, reduce joints and damage, and improve the overall performance and aesthetics of the concrete.

In the construction of industrial plants, slipform construction is a commonly used and efficient construction method; slipform construction usually adopts a hydraulic lifting system, and the support rod adopts a common construction steel pipe of Φ48×3.5, and the extrusion joint method is usually used to extend the support rod, that is, at the joint of the support rod, one end of the support rod with an outer diameter of φ48 is compressed to an outer diameter of φ40 by a hydraulic pipe compressor, and then fixed by a socket method, and finally the interface is sealed by welding. However, there are the following problems in extending the support rod using this method: 1. The verticality of the support rod is poorly controlled. When welding the steel pipe, the verticality of the steel pipe needs to be accurately corrected in advance, which increases the workload of the workers and makes it difficult to control; 2. The connection stability of the support rod is not easy to control. Since the interface of the steel pipe is sealed, weak welding points are prone to occur, and the integrity of the weld cannot be guaranteed. Connection failure may occur during the platform jacking process.

It can be seen from this that it is necessary to provide a connecting piece for extending the support rods, connect two support rods, and optimize the connection quality of the support rods to ensure construction convenience and improve construction efficiency.

In order to solve the problems that the supporting rods of the sliding form construction operation platform in the current construction engineering field have poor verticality and weak welding at the joints when extending, resulting in low construction efficiency and poor connection quality of the supporting rods, the utility model provides an extension component for the supporting rods of the sliding form platform, so as to change the traditional steel pipe butt welding connection method to connection through a connecting component, thereby achieving the effect of optimizing the connection quality of the supporting rods, ensuring construction convenience and improving construction efficiency;

The following is a detailed description of an embodiment of the utility model that provides an extension member for a support rod of a sliding platform. As shown in FIGS. 1-4 , the extension member includes a support rod body 1 , a first joint 2 , a second joint 3 and a connecting screw 4 ;

The supporting rod bodies 1 are provided with several ones, and the first joint 2 and the second joint 3 are fixedly provided inside the supporting rod bodies 1. The first joint 2 is placed at the upper end of the supporting rod body 1, and the second joint 3 is placed at the lower end of the supporting rod body 1. One end of the connecting screw 4 is threadedly connected to the first joint 2, and the other end is threadedly connected to the second joint 3, so that the several supporting rod bodies 1 are connected and fixed to each other.

Specifically, the first joint 2 and the second joint 3 are respectively provided at the two side ends inside the supporting rod, and the two supporting rod bodies are connected by threaded connection and fixing with the connecting screw 4, so as to achieve the effect of extending the supporting rod, and the relative positions of the two mutually connected supporting rods can be fine-tuned by rotating the connecting screw, so as to improve the verticality of the supporting rod after connection, and the supporting rod can be precisely adjusted by adjusting the tightness of the connecting screw 4 and the joint, so as to meet the verticality requirement; the first joint 2 and the second joint 3 connected by the connecting screw 4 are used to tightly fix the two supporting rods, and the connection between the supporting rods is tightly fitted and not easy to deform, that is, the supporting rod is extended by a connecting component instead of the existing butt welding method, so as to solve the problems of poor verticality and weak welding at the joints in the prior art.

Further, the first joint 2 and the second joint 3 are both hollow cylindrical members with hollow interiors, and the inner walls of the first joint 2 and the second joint 3 are provided with internal threads, and the internal threads are adapted to the threads of the connecting screw 4. Further, to ensure that the support rod has sufficient bearing capacity, the support rod body 1 adopts a steel pipe with an outer diameter of 48 mm and a wall thickness of 3.5 mm. After determining the size specifications of the support rod body 1, further, the outer diameters of the first joint 2 and the second joint 3 are 41 mm, and the inner diameters of the first joint 2 and the second joint 3 are 24 mm.

Furthermore, the diameter of the connecting screw 4 is set to correspond to the inner diameters of the first joint 2 and the second joint 3, and the diameter of the connecting screw 4 is 24 mm; the diameter of the connecting screw 4 is set to correspond to the inner diameters of the first joint 2 and the second joint 3 to ensure a close fit of the connecting parts and improve the firmness and stability of the connection.

Furthermore, the first joint 2 and the second joint 3 are spot-welded and fixed to the upper and lower ends of the support rod body 1 respectively. Spot welding and fixing have high working efficiency. The first joint 2 and the second joint 3 can be welded and fixed to the support rod body 1 only by spot welding and fixing at the joints.

Furthermore, the upper end and the lower end of the support rod body 1 are respectively provided with limit points, and the end of the first joint 2 close to the support rod body 1 is limited at the upper end limit point, and the end of the second joint 3 close to the support rod body 1 is limited at the lower end limit point. Specifically, by limiting the first joint 2 and the second joint 3 at the upper end and the lower end of the support rod cup body, respectively, the first joint 2 and the second joint 3 can be ensured to be fixed in the steel pipe. The setting of the limit points effectively prevents the connector from shifting or slipping inside the steel pipe, and the limit points can effectively share and transfer the load, and after the two support rods are connected by the connecting screw 4, the bearing capacity of the support rod is improved.

Furthermore, in a preferred embodiment, the length of the connecting screw 4 is 100 mm, and the length of the connecting screw 4 provides sufficient thread length to ensure that the first joint 2 and the second joint 3 can fully utilize the thread length of the connecting screw 4 for connection and fixation.

In a preferred embodiment, the first joint 2, the second joint 3 and the connecting screw 4 are made of carbon structural steel with high strength to ensure that the supporting rod after connection can withstand large loads and pressures. At the same time, the first joint 2 and the second joint 3 are integrally formed structural parts, and the carbon structural steel has good plasticity, so that the first joint 2 and the second joint 3 are processed into a hollow cylindrical shape with a hollow interior. After the first joint 2 and the second joint 3 are formed, they have high impact resistance and are not easy to break when squeezed, externally impacted or vibrated.

The first joint 2 and the second joint 3 are prefabricated and transported to the construction site for use. Before the support rod is installed, except for the first section of the support rod, the first joint 2 and the second joint 3 are respectively placed at the two side ports inside the support rod body 1, and limited at the limit position. The first joint 2 and the second joint 3 are fixed at the interface by spot welding, and one end of the connecting screw 4 is threadedly connected to the first joint 2 and rotated and tightened to fix one end of the connecting screw 4 to the support rod body 1, and the other end of the connecting screw 4 is threadedly connected to the second joint 3 of the other support rod body 1, and rotated and tightened until the two support rod bodies 1 are tightly fitted. The connection methods of multiple support rods are as described above and will not be repeated here. In this way, the extension of multiple support rods can be achieved. The above-mentioned connection method and connecting parts are used to convert the existing butt welding connection operation into ground operation, effectively reducing the use of welding machinery and improving construction safety.

The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
