Abstract
A steel backing mould is used for reinforcement arc welding which includes reinforcement joint gas protecting weld in the reinforced concrete project. The utility model is characterized in that a semi-cylindrical main body [1] is included, four parallel surfaces of the upper and the lower parts of a reinforcing plate [2] which extends from two ends of the semi-cylindrical body are separately tangential with the internal and the external circles of the semi-cylinder body, then a U-typed steel backing mould is formed. The utility model has the purpose of overcoming the deficiency existed in prior art, and providing a steel backing mould used for reinforcement arc welding in the reinforced concrete project, which is suitable for speedy construction of the reinforcement abutment joint arc welding in different types of reinforced concrete project. The utility model can effectively guarantee the quality of the reinforcement welding joint of novel reinforcement joint gas protecting weld and a polarity of traditional reinforcement arc welding abutting arts, simplify the operational art of the reinforcement arc welding, and reduce the joint cost.
Description
Technical field
The utility model belongs to reinforcing bar welding procedure technical field in the architectural engineering, specifically, relates to a kind of steel pad mould that is used for the reinforcing bar arc welding.
Background technology
Reinforced concrete structure is most widely used a kind of structure in the building construction, according to engineering structure characteristics and construction needs, has a large amount of splices to weld at the construction field (site).People's Republic of China's industry standard " reinforcing bar welding and control of acceptance " JGJ18-1996 requires to have clearly regulation to the reinforcing bar technology of arc welding: the molten ledge bar plumb joint of reinforcing bar need be used the angle steel backing plate, because the contact-making surface of reinforcing bar and angle steel backing plate is little, contact area is not bigger, and relatively deposited metal is just many; Reinforcing bar groove welding joint need be used billet, and when welding at the scene, flat bolster is also unsatisfactory to deposited metal protection effect; Reinforcing bar narrow gap welding need be installed copper mold and be welded, and this technological operation is cumbersome, and full section also can't be strengthened preferably; Therefore, said welding method fails generally to be applied.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of steel pad mould that is used for reinforced concrete works reinforcing bar arc welding, to adapt to the rapid construction of reinforcing bar banjo fixing butt jointing arc welding in all types of reinforced concrete works.
A kind of steel pad mould that is used for the reinforcing bar arc welding described in the utility model comprises semicylindrical main body, and four parallel surfaces up and down of the stiffener that extends from semicircle cylindrical shell both ends are tangent with semicylindrical inside and outside circle respectively, forms U-shaped steel pad mould.
A kind of steel pad mould that is used for the reinforcing bar arc welding described in the utility model, the length of its stiffener is less than or equal to 0.35 times of bar diameter to be welded.
A kind of steel pad mould that is used for the reinforcing bar arc welding described in the utility model is that carbon equivalent is not more than good carbon steel of 0.45% weldability or low-alloy structural steel.
The utility model not only can be used in several traditional reinforcing bar banjo fixing butt jointing technology of arc welding; can also be applied in the splice gas shielded arc welding technology newly developed; and help above-mentioned technology and obtain reliable quality reinforcing bar banjo fixing butt jointing; make above-mentioned technology of arc welding easy; reduce the joint cost simultaneously, guarantee the duration.
Description of drawings
Fig. 1 is a kind of front view that is used for the steel pad mould of reinforcing bar arc welding.
Fig. 2 is the left view of steel pad mould.
Fig. 3 is to use U-shaped steel pad mould to carry out the canonical schema of the embodiment of reinforcing bar arc welding.
Fig. 4 is the profile of Fig. 3 I-I.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described: an existing splice is by left reinforcing bar 7, right reinforcing bar 6, main weld 3, reinforcement of weld 4, reinforcement of weld 5 and comprise semi-cylindrical shaped main body 1 and two stiffener 2 formed U-shaped steel pad moulds are formed.Diameter is that left reinforcing bar 7 and the right reinforcing bar 6 of 25mm all is that the trade mark is the Ribbed Bar of the crescent rib of 20MnSi (same lot number), employed steel pad mould is that to adopt the trade mark be that the thin steel bar of Q235 (is of a size of 60 * 80 * 6mm) and is processed into special U-shaped mould with mechanical means, be lining in the splice bottom, left side reinforcing bar 7 is reserved with the 12mm gap with right reinforcing bar 6 formed splices, arc welding horizontal position welding technology is full with play movement welding filling by hand, and (welding current is 135～155 amperes to form joint main weld 3; Arc voltage is 20～28 volts; The employed welding rod trade mark is knot 507, and its diameter is 4mm).And steel pad mould stiffener and left reinforcing bar 7 and right reinforcing bar 6 contact positions are welded also full (welding current is 115～135 amperes; Arc voltage is 20～28 volts; The employed welding rod trade mark also is a knot 507, and its diameter is 4mm), form reinforcement of weld 4 and reinforcement of weld 5, this has just finished the reinforcing bar arc-welded joint of band steel pad mould.Aforesaid reinforcing bar electric arc welding steel pad mould is the standard component of typing, can select for use according to engineering design requirement and reinforcing bar state (comprising reinforcing bar nominal diameter, strength grade and reinforcing bar outer shape) to be connected during use.
