The utility model discloses rectangle fishplate and angle steel major chord fishplate cooperation are used, improve joint strength, and the installation location is accurate and processing preparation is simple.
Description
Technical Field
The utility model relates to a tower crane standard accessory technical field, concretely relates to a slice fishplate that is used for connecting between the tower crane frame.
Background
The existing tower body connected by the main chord fishplate of the angle steel is inconvenient to install due to the sectional property of the angle steel, needs to consume a large amount of manpower and material resources, and also needs to consume a large amount of materials during manufacturing. At present, the existing angle steel main string fishtail plate structure cannot meet the requirements of large and medium-sized tower cranes on tower bodies. However, there is no new fishplate structure in the market that can solve the above problems well.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the defect that exists among the prior art, provide a slice fishplate that is used for connecting between the tower crane frame, this rectangle fishplate uses with the cooperation of angle steel major chord fishplate, improves joint strength, and the installation location is accurate and processing preparation is simple.
In order to achieve the purpose, the technical scheme of the utility model is to design a sheet fishplate for connecting between tower crane frames, which comprises an integrally formed circular head part with a through hole and a rectangular tail part; the thickness of the circular head is larger than that of the rectangular tail, and the inner surface of the rectangular tail is a welding surface. The rectangular tail part is used for welding the rectangular fishplate with the base or the channel steel, and the circular head part is used for connecting adjacent angle steel or channel steel through the bolt, so that the stable connection of the tower body is facilitated.
As a preferable technical scheme, a connecting part is further arranged between the circular head part and the rectangular tail part, the thickness of the circular head part is smaller than that of the connecting part, the thickness of the rectangular tail part is also smaller than that of the connecting part, the circular head part and the inner surface of the connecting part are on the same plane, and the rectangular tail part and the outer surface of the connecting part are on the same plane; the inner surface of the rectangular tail part and the connecting part form a positioning groove, and the outer surface of the circular head part and the connecting part form a positioning bulge.
The internal surface of rectangle afterbody is the face of weld, and rectangle afterbody forms positioning groove with connecting portion, makes things convenient for welding position, has improved the stability of operation to compare in prior art, owing to also carried out welding reinforcement processing in positioning groove department, welding strength is higher. The outer surface of the rectangular tail part and the connecting part form a positioning bulge, the positioning bulge is used for positioning when another angle steel or channel steel is connected, the connection between the angle steel or the channel steel is stable, and the penetration of a bolt is facilitated.
Preferably, the outer edge of the circular head is provided with a toothed antiskid part. The toothed anti-slip part is arranged on the outer side of the circular head part, so that the workpiece can be conveniently carried and taken away, and is prevented from slipping.
According to a preferable technical scheme, the inner surfaces and the outer surfaces of the circular head part, the connecting part and the rectangular tail part are respectively provided with a reinforcing rib along the axial direction of the fishplate. Although the annular head part, the connecting part and the rectangular tail part are of an integrally formed structure, the reinforcing ribs are arranged along the axial direction of the fishplate in order to enhance the stress of the fishplate.
As a preferred technical scheme, a processing positioning through hole is formed in the center of the rectangular tail portion. The positioning through holes are used for machining the rectangular fishplates and serve as datum points of machining accessories.
The utility model has the advantages and the beneficial effects that: the inner surface of the rectangular tail part of the fishplate and the connecting part form a positioning groove, so that the connecting strength and the connecting precision of the fishplate and angle steel or channel steel are ensured; the outer surface of the rectangular tail part and the connecting part form a positioning bulge, so that the connection accuracy of the fishplate and another angle steel is ensured, the installation of the bolt is facilitated, and the efficiency of building the tower crane is greatly improved. The utility model relates to a simple and practical especially is fit for being used for large and medium-sized tower crane's construction.
