Abstract
The invention discloses a method for simply assembling double-webbed beams. The method comprises the following steps of 1, preparing materials for manufacturing two double-webbed beams which have the identical length, width and specification; 2, discharging; 3, making flanges and web plates into two box beams, and welding and assembling rib plates; 4, dividing upper and lower flanges of one of the two box beams to form two pieces of H-shaped steel; 5, assembling and welding the two pieces of H-shaped steel and the other box beam on a horizontal platform; and 6, dividing upper and lower flanges of the other box beam, and thus finishing manufacturing of the two double-webbed beams. By the method, joints on the outer side of a member, instead of the inner sides of the two web plates of each double-webbed plate are welded, so that the welding difficulty is reduced, the welding quality and efficiency are improved, the method does not have a special requirement on equipment, and the steps are simple; and method has the characteristic of simplicity.
Description
Technical field
The present invention relates to the assemble method of the two web griders of a kind of steel work.
Background technology
In power-plant engineering, be often designed with two web griders.During two web grider in running into part engineering, the weld seam welding that spacing because two web griders cross section is little, between two webs is little, operating personnel cannot be to two web griders two webs inner sides, and the edge of a wing and web are all thinner, after welding, easily produce welding deformation, after distortion, be difficult to correct.Therefore, by formulating reasonable and practical assemble method, make cannot welding position can weld, guarantee welding quality, be the emphasis that engineering is made.
Summary of the invention
The object of the present invention is to provide a kind of simple pair of web grider Simple assembled method.
The present invention is achieved in that
A pair web grider Simple assembled method, comprises the steps:
Step 1, be ready to two length and width sizes and the same required material of two web griders of specification, and make when preparing to carry out two two web griders, material comprises the edge of a wing at the upper and lower two ends of two web griders and the web of two web griders;
Step 2, respectively blanking is carried out to by twice design width in the edge of a wing at the upper and lower two ends of two web griders, two web grider webs are according to design size blanking;
Step 3, the edge of a wing after blanking is become to two box beam with web assembling, and carry out the welding assembly of gusset;
Step 4, the upper and lower edge of a wing of a box beam is wherein divided into two H shaped steel;
Step 5, on levels operation platform, two H shaped steel and second box beam after cutting apart are assembled, are welded;
Step 6, after the upper and lower edge of a wing of second box beam is cut apart; Completed the making of two two web griders.
Further scheme is: in step 4 and step 6, dividing method is carried out on the upper and lower edge of a wing of box beam: in the middle of the edge of a wing, toward both sides, cut, cut one section and stay one section, Deng cutting seam, at the position being started by centre not incision, cut off after cooling, two ends, the edge of a wing are reserved two sections and are not cut, and after all cuttings seams are cooling, more reserved position, two ends position are all cut off.
Further scheme is: after step 6 completes, continue to install all the other annexes on two web griders.
Further scheme is: described all the other annexes are bracket.
Further scheme is: after step 6 completes, the weld seam of former box beam inner side is welded.
The invention has the beneficial effects as follows: by above-mentioned assemble method, weld seam that originally cannot welding by two web griders two webs inner sides, is converted to the outside welding of member, thereby reduce welding difficulty, guarantee welding quality, improve welding efficiency, and without specific (special) requirements, above-mentioned steps is also simple to equipment; The present invention has the simple feature of method.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A pair web grider Simple assembled method, comprises the steps:
Step 1, be ready to two length and width sizes and the same required material of two web griders of specification, and make when preparing to carry out two two web griders, as accompanying drawing 1, material comprises the edge of a wing 1 at the upper and lower two ends of two web griders and the web 2 of two web griders;
Step 2, respectively blanking is carried out to by twice design width in the edge of a wing 1 at the upper and lower two ends of two web griders, two web grider webs 2 are according to design size blanking;
Step 3, the edge of a wing after blanking is become to two box beam with web assembling, and carry out the welding assembly of gusset 3, as shown in accompanying drawing 2,3; During welding operating personnel can be outside member welding box-shaped beam towards the weld seam in outside;
Step 4, the upper and lower edge of a wing of a box beam is wherein divided into two H shaped steel, as shown in accompanying drawing 4,5; For the distortion that prevents that cutting from producing, cutting method is gap cutting: in box beam, once cut apart place 5, in the middle of the edge of a wing, toward both sides, cut, cut one section and stay one section, cut off after waiting its cutting seam cooling at the position being started by centre not incision.Two ends, the edge of a wing are reserved two sections and are not cut, and cut according to the method for top flange bottom flange, reserved two sections of two ends position.After all cutting seams are cooling, more reserved position, two ends position is all cut off;
Step 5, on levels operation platform 4, two H shaped steel and second box beam after cutting apart are assembled, are welded, as shown in Figure 6; Now due to first divided opening of box beam, therefore outside the weld seam of former box beam inner side is exposed to, operating personnel can weld in member outside;
Step 6, after the upper and lower edge of a wing of second box beam is cut apart, for the distortion that prevents that cutting from producing, cutting method is gap cutting: at box beam secondary splitting place 6, in the middle of the edge of a wing, toward both sides, cut, cut one section and stay one section, at the position being started by centre not incision, cut off after waiting its cutting seam cooling.Two ends, the edge of a wing are reserved two sections and are not cut, and cut according to the method for top flange bottom flange, reserved two sections of two ends position.After all cutting seams are cooling, more reserved position, two ends position is all cut off; As shown in accompanying drawing 7,8, two two web griders 7 have been divided into.
In order to guarantee the intensity of two web griders, after having cut apart, due to second divided opening of box beam, therefore outside the weld seam of former box beam inner side is exposed to, operating personnel can weld in member outside, as shown in Figure 9;
After all the other annexes (bracket 8 etc.) of installing on two web griders, be finished product member, as shown in Figure 10.
