Abstract
The utility model relates to a high-bearing-capacity solid web type latticed steel column. The high-bearing-capacity solid web type latticed steel column comprises a left wing plate, a right wing plate and a web plate, wherein the left wing plate and the right wing plate are parallel and opposite to each other, and the web plate is arranged between the left wing plate and the right wing plate to form an I shape. According to the high-bearing-capacity solid web type latticed steel column, a soldering flux for submerged arc welding is added for protection during welding, so that active components of alloying elements in a welding seam are enhanced, the comprehensive mechanical properties of the integral welding seam are improved, and the quality defects generating during the conventional single gas shielded welding or submerged arc welding are greatly reduced to ensure that the surface of the welding seam is uniform and smooth, the appearance is beautiful, and the implementation effect is good.
Description
Technical field
The utility model relates to a kind of lattice steel column, relates in particular to the real abdomen formula of a kind of high-bearing capacity lattice steel column.
Background technology
The post of big-and-middle-sized industrial premises, large span public building, high-story house, light movable hosue room, working platform, trestle and support etc. adopts steel column mostly.Steel column can be divided into lattice column and real abdomen post by section form.The cross section of lattice column is divided into two limbs or many limbs, connects with lacing or batten plate between each limb, also claims on an empty stomach post, and is large when load, when shaft is wider, just adopt the empty stomach post, and rolled steel dosage is economized like this.Real abdomen post has whole cross section, and its steel column longitudinally arbitrary section is all identical, and such as H shaped steel, i iron, angle steel, channel-section steel, round steel, C shaped steel, Z-shape steel, square steel etc., wherein the most frequently used is H shaped steel and i iron.
Existing real abdomen post generally adopts the steel plate weld all around to form, and is welded with web in the middle of it.Existing welding procedure adopts submerged arc welding or carbon dioxide (CO
2) gas shielded arc welding.Submerged arc welding is a kind of method that electric arc burns and welds under welding flux layer.The equipment that submerged arc welding is mainly adopted has: the source of welding current, control cabinet, welding tractor etc., the advantage of submerged arc welding is that production efficiency is high, welding quality is high, can save welding material and the energy, the construction condition of labor is good, but its shortcoming is also comparatively obvious, the general main welding that the hand welding position is put welding and long weld seam that is applicable to.
CO
2Gas shielded arc welding is to utilize CO
2Do a kind of welding method of protective gas, its welding is a kind of automanual welding procedure.Its capital equipment adopts: the source of welding current, control cabinet, air supply system, wire feeder, welding gun etc.CO
2At the bottom of gas shielded arc welding has a cost, the advantage such as quality is good, production efficiency is high, but its shortcoming is to adopt larger power supply, and welding fabrication is attractive in appearance not, controls weldquality by operator's self-skill fully.
Existing welding procedure, the surface of the lattice steel column after welding easily produces the particle welding slag, need to manually root out, and this not only wastes time and energy, and production efficiency is not high, and has had influence on the quality of lattice steel column.
Summary of the invention
The deficiency that the utility model exists for prior art just provides the real abdomen formula of a kind of high-bearing capacity lattice steel column.
For addressing the above problem, technical solution adopted in the utility model is as follows:
The real abdomen formula of high-bearing capacity lattice steel column, described real abdomen formula lattice steel column comprises: left wing plate, right wing plate and web, left wing plate, right wing plate are parallel to each other relatively, between be provided with web, and composition " worker " font.
The utility model compared with prior art, implementation result of the present utility model is as follows:
The real abdomen formula of high-bearing capacity described in the utility model lattice steel column; the solder flux protection that adds submerged arc welding in the welding process; make that the effective ingredient of alloying element is strengthened in the weld seam; improved the comprehensive mechanical property of whole weld seam; greatly reduce and have the mass defect that produces in single gas shielded arc welding or the submerged arc welding now; make face of weld uniform and smooth, good looking appearance, implementation result is good.
Description of drawings
Fig. 1 is the structural representation of the real abdomen formula of high-bearing capacity described in the utility model lattice steel column;
Structural representation when Fig. 2 is the welding of the real abdomen formula of high-bearing capacity described in the utility model lattice steel column.
The specific embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, be the structural representation of the real abdomen formula of high-bearing capacity described in the utility model lattice steel column.The real abdomen formula of high-bearing capacity described in the utility model lattice steel column comprises: left wing plate 1, right wing plate 2 and web 3, left wing plate 1, right wing plate 2 and web 3 are the steel plate of certain specification size, left wing plate 1, right wing plate 2 are parallel to each other relatively, between be provided with web 3, and after forming " worker " font, welding fabrication again.
Structural representation during as shown in Figure 2, for the welding of the real abdomen formula of high-bearing capacity described in the utility model lattice steel column.Welding equipment described in the utility model comprises: welding tractor, welding gun 6 and welding wire 7 are installed, described welding gun 6 and welding wire 7 and existing CO on the welding tractor
2The mounting structure of gas shielded arc welding is identical, but CO is not installed
2Air supply system is by existing CO
2The power supply 4 of gas shielded arc welding, control cabinet 5 provide the power line operate control of going forward side by side for it.
At the place to be welded that left wing plate 1 contacts with web 3, heap has solder flux 8, and solder flux 8 adopts identical with the solder flux of existing submerged arc welding.Under the common cooperation of welding gun 6 and welding wire 7 and solder flux 8, finish the welding of left wing plate 1 and web 3.Similarly, under the common cooperation of welding gun 6 and welding wire 7 and solder flux 8, finish the welding of right wing plate 2 and web 3.
Above content is the detailed description of the utility model being done in conjunction with concrete preferred embodiment, can not assert that the utility model implementation only limits to these explanations.For the utility model person of ordinary skill in the field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to the scope of the utility model protection.
