Abstract
The utility model provides an assembly structure. The assembly structure comprises an anode head, two sides of the male head are respectively connected with left channel steel and right channel steel, welding gaps between the left channel steel and the male head and between the right channel steel and the male head are both four millimeters, the male head is in a Y-shaped structure, the Y-shaped structure is composed of a U-shaped structure and a vertical line structure, the left side of the U-shaped structure is welded to the left channel steel in an installing mode, and the right side of the U-shaped structure is welded to the right channel steel in an installing mode. The welding gaps not only meet requirements for intensity and rigidity, but also meet the requirement for thermal stress contraction. The assembly structure ensures the intensity of workpieces, saves welding materials, reduces production cost, and increases actual economic benefit.
Description
Technical field
The utility model relates to a kind of splicing structure, specifically a kind of sun head and channel-section steel splicing structure of truss sheet.
Background technology
No matter combined bridge still is being on the national defence in rescue and relief work and other urgent occasion; More and more bring into play its important function; Its length is also more and more long; Have several kilometers even tens kilometers, quality and its middle-jiao yang, function of the spleen and stomach head that the assembly unit weldquality of truss sheet has determined the truss sheet and cloudy head and the assembly unit weldquality of both sides channel-section steel have determined the combination quality of trussed construction, have also determined the quality of bridge.In the process by original design manufacturing and use, find the channel-section steel crackle to occur positive assembly unit commissure with channel-section steel.
Summary of the invention
In order to address the above problem, the utility model provides a kind of splicing structure, guaranteed workpiece intensity, saved wlding, solve the problem that occurs the channel-section steel crackle in sun head and the assembly unit commissure of channel-section steel.
In order to achieve the above object, the utility model is realized through following technical scheme: the utility model is a kind of splicing structure, comprises positive head, connects left channel-section steel and right channel-section steel respectively in the both sides of sun head, and left channel-section steel and right channel-section steel are 4 millimeters with the weld seam of sun head.
The further improvement of the utility model is: the sun head is a Y shape structure.
The further improvement of the utility model is: Y shape structure is made up of U-shaped and 1 shape, and said 1 morpheme is in the bottom of said U-shaped.
The further improvement of the utility model is: the left side of this U-shaped and left channel-section steel assembly welding and its right side and right channel-section steel assembly welding.
Compared with prior art, the beneficial effect of the utility model: the utility model is simple in structure, guaranteed workpiece intensity, saved wlding, alleviated cost of production, increased actual economic benefit, solved generation channel-section steel problem of cracks.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the A-A sectional drawing of the utility model.
The specific embodiment
In order to deepen understanding to the utility model, will combine the embodiment and the specific embodiment that the utility model is done below and further describe, this embodiment only is used to explain the utility model, does not constitute the qualification of scope that the utility model is explained.
Shown in Fig. 1-2; The utility model is a kind of splicing structure, comprises sun 1, connects left channel-section steel 2 and right channel-section steel 3 respectively in the both sides of said sun 1; The weld seam of said left channel-section steel 2 and right channel-section steel 3 and said sun 1 is 4 millimeters; Said sun 1 is a Y shape structure, and said Y shape structure is made up of U-shaped and 1 shape, the left side of this U-shaped and left channel-section steel 2 assembly weldings and its right side and right channel-section steel 3 assembly weldings.In welding, to bear bigger thermal stress on the wall of the weld of channel-section steel, when thermal stress during, will produce the crack greater than allowable stress, the utility model weld seam angle height is 4 millimeters, the thermal stress of channel-section steel weld can not produce the crack less than this allowable stress.
The utility model is simple in structure, guaranteed workpiece intensity, saved wlding, alleviated cost of production, increased actual economic benefit, solved generation channel-section steel problem of cracks.
