Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated strip foundation construction, in particular to a prefabricated formwork structure for a strip foundation of a belt conveyor support in a coal conveying system. Background Art

[0002] The coal transportation system is an important part of the production system in the coal field. The coal conveyor belt support is the main equipment for coal transportation. The height of the belt conveyor support is basically 2 to 3 meters, and the support arrangement distance is between 1 and 2 meters. It is basically parallel to the ground and the support spacing is small. The transportation distance is long. There is a strip foundation at the bottom of each group of supports. Due to the large number, small size and long construction front, this type of foundation is generally constructed by centralized prefabrication and on-site installation. The traditional prefabricated strip foundation construction generally adopts the upright method, that is, the embedded parts and lifting rings are installed on the upper part of the prefabricated foundation mold, and are connected and fixed with the foundation structural steel bars by binding and welding. When this method is used for concrete pouring, the embedded parts and lifting rings will inevitably undergo slight displacement due to the influence of vibration. During pouring, the embedded parts on the top of the prefabricated foundation are very easy to be contaminated. Once contaminated, it is time-consuming and labor-intensive to clean up later, which affects the subsequent installation work. Due to the narrow width of this type of foundation, the working surface of the vibrating rod is easily restricted during the concrete pouring and vibration operation, and the lower part of the embedded parts is not easy to be vibrated into place. The reinforcement of the embedded parts is easily affected by vibration. After the construction is completed, problems such as hollowing and position deviation of the embedded parts are prone to occur. The installation precision of embedded parts of strip foundation with brackets is high, and the surface flatness tolerance is required to be ≤2mm. Once hollowing and displacement occur in embedded parts, the following consequences will occur: 1) Once a positive error occurs in the elevation of individual embedded parts, other embedded parts must also be installed with gaskets when the equipment is installed, which will increase costs and delay the construction period, and increase manpower and material resources; 2) Hollowing will loosen the connection between the upper belt bracket and the foundation, causing relative movement between the embedded parts and the concrete, thereby reducing the strength of the entire structure and causing deformation of the upper belt bracket; 3) The coal conveyor belt bracket will vibrate during operation and transmission, and the embedded parts may fall off or loosen during the operation of the equipment, becoming a potential safety hazard. Therefore, this field needs a prefabricated formwork structure for the strip foundation of the belt conveyor bracket of the coal conveying system to solve the above problems. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, that is, to solve the problems in the prior art that the embedded parts and hanging rings of the prefabricated foundation of the belt support are prone to hollowing, displacement and surface pollution during production, the utility model provides a prefabricated formwork structure for the strip foundation of the belt conveyor support of the coal conveying system.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a prefabricated mold structure for the strip foundation of the belt conveyor support of the coal conveying system, comprising a rear side plate of the mold body, a left side plate of the mold body, a right side plate of the mold body, a left bottom plate of the mold body, a middle bottom plate of the mold body and a right bottom plate of the mold body, the left bottom plate and the right bottom plate of the mold body are respectively located on the left and right sides of the middle bottom plate of the mold body, and the height of the middle bottom plate of the mold body is higher than the left bottom plate and the right bottom plate of the mold body; the left bottom plate and the right bottom plate of the mold body are respectively provided with limit holes for the lifting rings to pass through, the limit holes are installed in the limit holes, and the lifting rings are provided with limit plates, which are fixedly connected to the upper surface of the left bottom plate or the right bottom plate of the mold body; the left bottom plate and the right bottom plate of the mold body are also respectively provided with embedded iron parts, the embedded iron parts include anchor plates and anchor bars, and the top surfaces of the anchor plates of the embedded iron parts are provided with rubber strips, and the top surfaces of the anchor plates of the embedded iron parts are bonded to the upper surfaces of the left bottom plate and the right bottom plate of the mold body by rubber strips.

[0005] Preferably, the rubber strip is made of rubber.

[0006] Preferably, the hanging ring has a U-shaped structure.

[0007] Preferably, the left and right sides of the bottom plate in the mold body are respectively connected to the left bottom plate and the right bottom plate of the mold body through short side plates.

[0008] Preferably, the limiting socket is shaped as a vertical slot, and the limiting socket matches the size of the corresponding lifting ring.

[0009] Preferably, threaded holes are respectively provided at the four corners of the anchor plate of the embedded iron parts, and matching threaded nails are provided in the threaded holes for connecting and fixing with the left bottom plate or the right bottom plate of the mold body.

[0010] Preferably, threaded holes are provided at both ends of the limiting plate, and matching screw threads are provided in the threaded holes. The limiting plate is connected to the left bottom plate or the right bottom plate of the mold body through the screw threads.

[0011] The beneficial effects of the utility model are: 1. When the prefabricated formwork structure is constructed by the inverted method, the embedded iron parts are changed from the traditional upright installation to the inverted installation, which makes positioning and leveling easy, saves construction time, and solves the quality problems such as hollowing under the embedded parts after the prefabricated foundation is completed; 2. By opening limiting holes on the bottom plate of the formwork, the embedded iron parts and the lifting rings can be accurately positioned and fixed on the bottom plate of the formwork according to the designed position by screw nails, and the displacement of the lifting rings and the embedded iron parts is effectively avoided during concrete pouring; 3. When the embedded iron parts are installed, sealing strips are arranged on the anchor plate on the top of the embedded iron parts, which enhances the tightness of the combination of the embedded iron parts and the bottom plate of the formwork, and effectively avoids the contamination of the surface of the embedded iron parts during concrete pouring.
