Abstract

The utility model relates to a steel structure closure clip which comprises a strap clamp connected between an installed truss and a closure section truss. A circular arc gap is formed in the middle of the bottom edge of the strap clamp and in the closure seam position, the welding edge is from one end of the gap to one end of the bottom edge of the strap clamp, and the non-welding edge is from the other end of the gap to the other end of the bottom edge of the strap clamp. By using the steel structure closure clip, the size of the gap of the closure gap during closure can be controlled, the welding amount and the welding residual stress can be reduced, the welding quality of the closure gap can be ensured, and the overall stability of the structure can be enhanced. The steel structure closure clip can ensure the safe and high-quality welding of butt-jointed seams of closure gap components, and can ensure that the tension failure phenomenon can not happen during the welding process of the butt-jointed seams of the closure gaps. The steel structure closure clip can be widely applied to projects with large quantity of steel structure closure gaps, large welding amount and long welding time of the butt-jointed seams of the closure gap components.

Description

Steel construction closes up Karma

Technical field

The utility model relates to a kind of steel construction that is used for fixing and closes up mouthful connecting elements of member butt weld position.

Background technology

For steel construction close up that mouthful quantity is many, welding capacity is big, close up mouthful engineering of member butt weld welding longer duration, the installation of closure segment is along with the overall installation process of engineering is carried out in different time, the installation quality of closure segment not only influences the safety in the structure installation process, and influences final closing up and the overall construction quality of structure and the safety in the structure use.But close up in mouthful butt weld welding process often easily because of the tensile failure phenomenon appears in variations in temperature, therefore, must take rational mounting process measure, guarantee the installation of closure segment and associated components and closing up smoothly of structure.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of steel construction to close up Karma, solve the traditional tensile failure phenomenon appears in mouthful butt weld easily because of variations in temperature in welding process problem of closing up.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of steel construction closes up Karma, comprise and be connected in the clamp of adorning between truss and the closure segment truss, it is characterized in that: middle part, the base of clamp, be positioned at and close up the gap that seaming position has a circular arc, gap one end is a welding edge to clamp base one end, and the gap other end to the clamp base other end is non-welding edge.

The welding edge bilateral symmetry of described clamp is welded with a pair of stiffener, and stiffener is vertical with clamp two plate faces, and the base of stiffener is concordant with the base of clamp.

Described stiffener can be triangular plate, trapezoidal plate or rectangular slab.

The thickness of described clamp is not less than 20mm, highly is not less than 250mm, and length is not less than 500mm, and the radius of gap is not more than 30mm.

The beneficial effects of the utility model are:

The utility model can be controlled the gap length that closes up mouth when closing up, and reduces the welding capacity and the welding residual stress that close up mouth, guarantees to close up the welding quality of mouth, can strengthen the resistance to overturning of structure.The utility model can safe and high-quality assurance close up finishing of mouthful member butt weld welding, can guarantee the tensile failure phenomenon can not occur in the welding process of closing up mouthful butt weld.

The utility model can be widely used in that steel construction closes up that mouthful quantity is many, welding capacity is big, close up mouthful engineering of member butt weld welding longer duration.

Reference numeral: 1-clamp, 2-stiffener, 3-gap, 4-adorned truss, 5-closure segment truss, 6-welding edge, 7-non-welding edge.

The specific embodiment

Embodiment is referring to Fig. 1, shown in Figure 2, a kind of steel construction closes up Karma, comprise and be connected in the clamp of adorning between truss 4 and the closure segment truss 51, middle part, the base of clamp 1, be positioned at and close up the gap 3 that seaming position has a circular arc, the sagitta of gap 3 is less than or equal to the radius of circular arc, and gap one end is a welding edge 6 to clamp base one end, and the gap other end to the clamp base other end is non-welding edge 7.

The welding edge bilateral symmetry of described clamp 1 is welded with a pair of

stiffener

2, and 1 liang of plate face of stiffener 2 and clamp is vertical, and the base of stiffener 2 is concordant with the base of clamp 1.The stiffener 2 of present embodiment is a triangular plate, but also can be trapezoidal plate or rectangular slab.

The thickness of above-mentioned clamp 1 is not less than 20mm, highly is not less than 250mm, and length is not less than 500mm, and the radius of gap 3 is not more than 30mm.The material of clamp 1 is Q235B.

Application Example of the present utility model is referring to Fig. 3, Fig. 4, the top flange plate and the bottom wing listrium that close up mouthful section respectively are provided with three Karmas, the Karma of top flange plate and bottom wing listrium mainly works to bear vertical force, biside plate respectively is provided with two Karmas, the Karma of biside plate mainly plays a part spacing and bears horizontal force, can increase the lateral stability of agent structure.Setting up specification on the Karma on both sides, top flange is the leg-of-mutton stiffener 2 of 100 * 100 * 10mm, except that the Karma of lower flange be weldingly fixed on adorn on the main couple 4, other Karma all is weldingly fixed on the closure segment truss 5.It is that fillet weld size is not less than 14mm that weld seam during welding requires, and adopts twin fillet wolt.

Size of the present utility model and number needs determine that according to the Force Calculation at this interface position this Force Calculation not only will be considered to overlap force request in the closure segment installation process, and will consider to close up the force request that closes up mouth in the process, comprise the stressed of member bodies.

The application course of work of the present utility model is: the Karma welding that will close up mouth earlier is fixing, and then closes up mouthful welding of butt joint main weld, docks to cut off Karma after main welding finishes.
