Background

The majority of the company built thin slab sections exceed 10 meters, and the number of the thin slab sections is about 500 and is more than 10 meters, and the operation cannot be expected due to the influence of a thin slab section production line for special reasons. Therefore, the sheet segmentation is changed from the on-line production of the sheet segmentation into the off-line production. Due to the environmental requirements of the sheet construction, in open-air construction during heavy rain, dripping rain water falls onto the machined components, which causes poor welding quality and sometimes requires repair or rework, which causes additional heat input and deformation of the sheet, so that the sheet sections are more suitable for construction in the workshop.

At present, the jointed sheets of the thin plates are spliced by adopting a submerged-arc welding mode, and the welding seam requirement can be met only by turning over and welding the thin plates by adopting the submerged-arc welding. However, the maximum turning height of the mainboard spliced plate in a company straight workshop is 10 meters, and the requirement of the turning height during the splicing of the thin plates cannot be met; and the gyro wheel on the support frame on the production line can't satisfy the requirement of sheet flatness owing to mutual interval is big, if the sheet metal directly places and moves on the gyro wheel moreover, because the roll of gyro wheel is unstable can lead to the sheet metal to warp at the removal in-process. Therefore, the existing non-thin plate sectional production line cannot meet the requirement of thin plate construction.

Therefore, the technical problem to be solved by the invention is to provide a sheet splicing support for an interior workshop, which can prevent a large sheet from being deformed in a sectional manner. The sheet splicing support can be used for constructing large sheet sections in an interior workshop, and is simple to operate, high in safety, high in construction precision and good in finishing quality.

The connecting device is arranged, so that the two brackets can be spliced through the connecting device, and the brackets can meet the splicing requirements of the thin plates with different sizes.

As will be understood with reference to fig. 3 and 4, the connecting device includes a first limiting member 601, a second limiting member 602, and a pin member 603, one side surface of the first limiting member 601 in the longitudinal direction is connected to the side surface of the peripheral plate 50, one side surface of the second limiting member 602 in the longitudinal direction is connected to the side surface of the peripheral plate 50 of another bracket, the first limiting member 601 is located above the second limiting member 602, and the first limiting member 601 and the second limiting member 602 are detachably connected by the pin member 603. The two brackets are limited by the first limiting piece 601 and the second limiting piece 602, and the movement between the first limiting piece 601 and the second limiting piece 602 is limited by the bolt, so that the relative movement of the two brackets is limited.

In this embodiment, the first limiting member 601 and the second limiting member 602 are both L-shaped plates, the first limiting member 601 and the second limiting member 602 are spliced into a rectangular parallelepiped, horizontal portions of the first limiting member 601 and the second limiting member 602 are both provided with through holes correspondingly, the pin member 603 is inserted into the through holes, and the pin member 603 is a tapered pin. The first limiting piece 601 and the second limiting piece 602 are limited in the length direction by the matching of the L-shaped plates, and the first limiting piece 601 and the second limiting piece 602 are limited in the width direction by the bolt piece 603. The latch member 603 is provided as a taper for convenience, and the latch member 603 is disassembled. In the embodiment, the first limiting member 601 and the second limiting member 602 are formed by welding an L-shaped plate with a length of 500mm, a width of 150mm and a thickness of 40mm and a steel plate with a length of 150mm, a width of 40mm and a thickness of 40 mm.

In this embodiment, a plurality of hanging horses are further provided on the carriage, the hanging horses are connected to the base plate 10 or the support assembly 20, and the top of the support assembly 20 is higher than the hanging horses. The lifting horse is arranged on the bracket, so that the bracket is convenient to lift when in use. It should be noted that, the connection among the bottom plate, the first supporting member, the second supporting member, the first reinforcing member and the second reinforcing member is welded.

As shown in fig. 5, the present embodiment further provides a method for using the bracket, which is suitable for the bracket, and the method for using the bracket includes the following steps:

s11, hoisting the bracket to the production line;

if the number of carriers is more than 1, the process proceeds to step S12, and if the number of carriers is one, the process proceeds directly to step S13,

s12, adjusting the distance between the two brackets, and connecting the two brackets;

s13, placing the thin plates to be spliced on a bracket;

the production line is provided with rollers which are spaced from each other, the bottom plate 10 is placed on the rollers, the distance between the two brackets can be adjusted by pushing the bracket, and the distance between the two brackets is 100 mm.

Wherein, the distance between the two brackets is adjusted by the rolling of the rollers by placing the floor on the rollers on the production line; the two brackets are connected to increase the area of the supporting surface of the brackets, so that the brackets can adapt to thin plates with different sizes.

When the plate is constructed by splicing and segmenting a thin plate with the length of 16m, the width of 10m and the thickness of 12mm, the construction can be completed by using only one bracket. For thin plates with the width of 16m and the width of less than 10m and the thickness of less than 12mm, one bracket can not meet the process requirements, and the requirements can be met only after two brackets are used for splicing. Therefore, for the thin plate which can meet the requirement after being spliced by connecting the brackets, when the brackets are used, the lifting horses on the two brackets are connected with the crane, then the brackets are lifted to the production line by the crane, then the distance between the two adjacent brackets is adjusted by the rollers on the production line, and the distance between the two brackets is preferably adjusted to be 100 mm. The two brackets are then connected using the pins on the two connecting devices 60. This results in an oversized support surface of length 16m and width exceeding 21.6 mm. And then hoisting the two sheets with the width of 10m and welded non-structural surfaces or the sheets with the front and back surfaces welded to the bracket to be spliced. Moreover, the present embodiment provides a bracket that can be spliced three or more.

As shown in fig. 6, the present embodiment further provides a method for splicing sheets, which splices the sheets through the bracket as above, and includes the following steps:

s21, aligning the butt seam of the thin plates placed on the brackets with the gap between the two brackets;

s22, adjusting CO₂The gap of the weld;

s23, attaching a pad to the back of the thin plate; the two sheets and the liner form a welding groove, and the liner is a ceramic liner;

s24, using CO₂Priming, dual filament CO₂And the cover surface welding process is used for splicing and welding the two thin plates.

In the scheme, the back of the thin plate is pasted with the liner to enable the thin plate and the liner to form a welding groove, so that single-side welding and double-side forming are achieved, and splicing can be achieved without turning over during the splicing process of the thin plate. The ceramic and the metal are not wetted, so the ceramic is used as a liner, and the liner is convenient to separate from the thin plate after welding.
