Abstract

The utility model relates to a high-intensity cable bridge frame, comprising trough structures and a cover plate, wherein two lateral faces of the two ends of the trough structures are provided with connecting holes, and the trough structures are clamped with the cover plate by a sticking fastener, and the two trough structures are connected by the connection straps. The key points of the utility model are that the bridge frame is provided with a plurality of stiffeners which are parallel to the length of the frame body. The stiffeners can spread in the bottom of the trough structures, or at the bottom of the trough structures and the cover plate, or at the bottom and lateral sides of the trough structures, or at the bottom and the lateral sides of the trough structures and the cover plate. The utility model not only enhances the intensity and hardness of the bridge frame to adapt to large span's installation and application, but also saves raw materials, and lightens the weight of the bridge frame body.

Description

The high-strength cable crane span structure

Technical field

The utility model relates to the built on stilts device of installing of cable, particularly a kind of high-strength cable crane span structure.

Background technology

Traditional slot type, pellet type, ladder-type cable bridge all are to adopt shear, crimp, piercing and shaping die, and under the situation that the specification of cable testing bridge is determined, the intensity of its product, rigidity often depend on the thickness of steel plate materials.Therefore traditional cable testing bridge is in the bearing capacity of integral body, big span, all not satisfactory from aspects such as weight.

Summary of the invention

The purpose of this utility model provides the cable testing bridge of a kind of high strength and light self-weight, to overcome the weak point of traditional cable crane span structure.

The purpose of this utility model is achieved through the following technical solutions.

The high-strength cable crane span structure, formed by cell body and cover plate, wherein has connecting hole on the two sides at cell body two ends, cell body and cover plate by fastener mutually pincers close, can connect by brace between two cell bodies, its invention main points are to have some the reinforcements that parallel with support body length on crane span structure, and this reinforcement can be distributed on the bottom of cell body or cell body bottom and the cover plate or bottom cell body bottom and side or the cell body and on side and the cover plate.

The cable testing bridge made from the steel plate of same thickness is compared with traditional cable testing bridge like this, the whole bending resistance of its crane span structure cuts the phantom amount to be increased greatly, therefore the utility model has not only strengthened the crane span structure strength and stiffness, can adapt to installing and using of big span, and can also save raw material and alleviate the weight of self.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

With reference to Fig. 1, the high-strength cable crane span structure is made up of cell body 1 and cover plate 2, and wherein the both sides at cell body 1 two ends have connecting hole 4, cell body 1 and cover plate 2 by fastener 5 mutually pincers close.On cable testing bridge, also have some the reinforcements 3 that parallel with support body length.Reinforcement 3 generally has following several on cable testing bridge: A, only be distributed in cell body 1 bottom; B, be distributed on cell body 1 bottom and the cover plate 2; C, be distributed in cell body 1 bottom and side; D, be distributed on cell body 1 bottom and side and the cover plate 2.Wherein that relatively more commonly used is two kinds of B, D, though this is because cover plate 2 is not the main carrier as load, but the rigidity that has increased cover plate 2 self after the reinforcement 3 has been arranged, move in the process phenomenon of having avoided the cover plate 2 of length to deform and bend like this in the installation of erecting cable construction.

The reinforcement 3 that this accompanying drawing shows is distributed on cell body 1 bottom and side and the cover plate 2.Wherein, cell body 1 bottom has 2 reinforcements 3, and the dual-side of cell body 1 respectively has 1 reinforcement 3, has 1 reinforcement 3 on cover plate 2.

With reference to Fig. 2, the cell body 1 that this accompanying drawing shows only has 1 reinforcement 3 in its bottom, and its dual-side still is a platen surface, the cable testing bridge of this version, and use in the place that is suitable for underload, little span.

The sectional view that is cell body 1 that Fig. 3, Fig. 4 show.Wherein, the reinforcement 3 that Fig. 3 is shown, its structure is the boss shape; The reinforcement 3 that Fig. 4 is shown, its structure are arc shape.

Fig. 5 is the configuration diagram of fastener 5, and its effect is to make cell body 1 and cover plate 2 pincers synthesize as a whole.

Fig. 6, Fig. 7 are respectively the configuration diagram of outer brace 6 and interior brace 7, and its effect is the connection that realizes between two cell bodies 1 by the connecting hole 4 of cell body 1 end, makes cable testing bridge development length according to actual needs.

Fastener 5, outer brace 6 and interior brace 7 are prior art.

The design is in the making to reinforcement 3, and craft science is convenient, is to adopt cold-working rolling forming technology.Take the rolling forming technology, not only increase work efficiency, and in the roll extrusion process, use the mechanism of flow harden, increased crane span structure and given stress, its strength and stiffness are improved greatly, material reduces from weight.The utility model and manufacture craft thereof, not only can high efficiency, high-quality makes the cable testing bridge of common specification, satisfy large-engineering, the needs that use in enormous quantities, can also factory length reach 6 meters, 9 meters and be applicable to the needed large span cable bridge rack of steel roof truss factory building.
