Description

Technical Field

[0001] The invention relates to the field of windbreak sheds, and in particular to a modular windbreak shed for high-altitude operations of steel structures and a construction method thereof. Background Art

[0002] In the process of nuclear power project construction, a large number of stone piers and columns need to be built to ensure the stability and firmness of the building. In order to increase the stability of the building, a welding platform usually needs to be installed on the stone piers and columns to facilitate welding work. In high-altitude operations on steel structures, in order to ensure the quality of welding, a windbreak is often required to be set up to resist the influence of bad weather. The existing technology usually adopts the method of setting a bracket on the aerial work platform to fix the windbreak cloth. However, this method has the problems of cumbersome construction and great safety hazards.

[0003] For example, the Chinese utility model patent (application number: CN200820301609.2) discloses a "windbreak shed for low-temperature welding of building steel structures". Its specification discloses: There are two main sources of windbreak sheds currently used on construction sites. One is to purchase finished products, and the other is to build them on site. Purchased windbreaks will increase construction costs, and it takes a certain amount of time from purchase to transportation to the construction site, which may delay the pre-set construction schedule. Moreover, if they are used for the second time, they need to be transported again. The traditional way to build a windbreak shed on site is to erect it outside the proposed component. The disadvantage is that the windbreak shed is large in size, complex in structure, and time-consuming and labor-intensive to construct and disassemble. The above patents can prove the defects of the existing technology.

The fixing assembly 3 includes a pull plate 301. The modular bracket 2 includes a prefabricated component 201. The prefabricated component 201 is divided into an upper and lower part. An outer protective net 202 is fixedly installed on the outer side of the upper part of the prefabricated component 201, and an inner protective net 203 is slidably connected to the inner side. A bottom protective net 204 is movably hinged on the top of the lower part of the prefabricated component 201. A top winding rod 213 and a bottom winding rod 214 are rotatably installed on the top and bottom of the upper inner cavity of the prefabricated component 201, respectively. A support plate 211 is vertically slidably clamped at the top of the inner cavity, and a windproof cloth 210 is fixedly connected to the bottom of the support plate 211. The windproof cloth 210 passes around the bottom winding rod 214 at the bottom and passes around the top winding rod 213 at the top to extend from the top inner side of the prefabricated component 201. The outer side of the windproof cloth 210 is fixedly connected to the inner side of the pull plate 301. Cavities are opened on both sides of the prefabricated component 201, and a pair of support springs 212 are fixedly installed at the bottom of the cavities on both sides.

The pull plate 301 stretches the windproof cloth 210 out, and the four pull plates 301 in the middle stretch the windproof cloth 210 out and fix them on the stone pillars in the middle.

[0044] First, three prefabricated components 201 are fixedly installed on the four sides of the welding platform 1, and the bottoms of the three prefabricated components 201 are fixedly installed on the sides of the welding platform 1. After the prefabricated components 201 are fixed, the windproof cloth 210 in the middle of the upper part of the prefabricated component 201 is pulled out through the pull plate 301, and after the windproof cloth 210 is pulled open, the pull plates 301 on the inner side of the prefabricated components 201 in the middle of the four faces are pulled out and fixed to the four faces of the column, and then the pull plates 301 on both sides of the four faces are pulled outwards respectively, and pressed to the top of a windproof cloth 210 in the middle of the adjacent sides.

[0046] The prefabricated component 201 is divided into an upper part and a lower part. The inner and outer sides of the upper part are respectively provided with an outer protective net 202 and an inner protective net 203, and the windproof cloth 210 is stored therebetween, thereby providing good protection for the windproof cloth 210 and preventing it from being damaged during transportation and installation. At the same time, a bottom protective net 204 that can be opened inward is installed at the lower part of the prefabricated component 201. After the upper inner protective net 203 is pulled down, the lower bottom protective net 204 can be sealed. After the inner protective net 203 is pulled up, the bottom protective net 204 can be used as a vent to ventilate the inside of the welding platform 1, thereby achieving not only protection for the windproof cloth 210, but also convenient ventilation and heat dissipation.

[0058] Step 3: First, the windproof cloth 210 is pulled out from the inside of the prefabricated component 201 by pulling the four pulling plates 301 in the middle, and the pulling plates 301 are fixedly installed on the stone pillars for fixing;

[0059] Step 4, then pull out the pull plates 301 at both ends of the same side in turn, and pull the pull plates 301 to the top of the windproof cloth 210 on the other side, so that the inner end of the telescopic groove 304 will clamp the positioning groove 303 on the back of the pull plate 301 pulled out from the middle of the adjacent side into the inside, thereby pushing the telescopic groove 304 in the middle of the pull plate 301 outward to clamp the telescopic rod 309 into the fixing groove 208 on the top of the prefabricated component 201 in the middle of the adjacent side, and so on, pull out all the eight pull plates 301 on the four corners and fix them.

[0060] The modular windproof shed for high-altitude steel structure operations and the construction method provided by the present invention are used as follows:

[0061] First, three prefabricated components 201 are fixedly installed on the four sides of the welding platform 1 respectively, and the bottoms of the three prefabricated components 201 are fixedly installed on the sides of the welding platform 1. After the prefabricated components 201 are fixed, the extension plates 205 on both sides of the two adjacent prefabricated components 201 are docked and inserted into each other's slots 207. At this time, the docking holes 215 on both sides of the top of the prefabricated component 201 will be aligned with the docking slots 206 opened on the inner side of the extension plates 205, so that the docking blocks 308 on both sides of the bottom of the pressing plate 305 are inserted into the docking holes 215 and the inside of the docking slots 206, and then the two adjacent prefabricated components 201 are limited and fixed. The prefabricated components 201 at the four corners are fixed with bolts to the overlapping extension plates 205, and the middle of the upper part of the prefabricated component 201 is pulled by the pull plate 301. The windproof cloth 210 is pulled out, and after the windproof cloth 210 is pulled open, the pull plates 301 on the inner side of the prefabricated component 201 in the middle of the four faces are pulled out and fixed to the four faces of the column, and then the pull plates 301 on both sides of the four faces are pulled outward respectively, and pressed to the top of a windproof cloth 210 in the middle of the adjacent sides, and the pull plates 301 are fixed to the back of the middle pull plates 301, so as to shield the upper part of the prefabricated component 201 on the top and sides of the welding platform, and then the inner protective net 203 on the inner side of the upper part of the prefabricated component 201 is pulled to the bottom to overlap with the bottom protective net 204, so that the inner protective net 203 and the bottom protective net 204 shield each other, so as to achieve shielding of the lower part of the prefabricated component 201, and after the inner protective net 203 is pulled up, the bottom protective net 204 can be used as a vent to ventilate the inside of the welding platform 1;

[0062] After all the windproof cloths 210 on the four sides of the welding platform 1 are fully unfolded, the four middle pull plates 301 are fixed to the middle column, and then the pull plates 301 on both sides are directly pulled out to the top of the windproof cloth 210 in the middle of the adjacent side, and the windproof cloths 210 on both sides are pressed to the top of the windproof cloths 210 in the middle of the two sides, and then the telescopic groove 304 opened in the middle of the pull plate 301 is used to clamp the fixed plate 302 on the back of the pull plate 301 into the inside, so that the telescopic rod 302 in the telescopic groove 304 is 9 is pushed out, and then the telescopic rod 309 in the middle of the inner cavity is extended into the fixing groove 208 opened on the top side of the prefabricated component 201 for fixing. After the telescopic rod 309 is inserted into the fixing groove 208, the pressing plate 305 can be controlled to move downward by the pressing rod 307 to engage and fix the positioning groove 303 through the positioning block 306, thereby fixing the telescopic rod 309 inserted into the fixing groove 208. At the same time, the overlapping and limiting positions also have a reinforcing effect on the windproof cloth 210.

[0063] After the windproof cloth 210 is stored inside the prefabricated component 201, the pull plate 301 is attached to the side of the top of the prefabricated component 201, and the fixing plate 302 on the back of the pull plate 301 is inserted into the fixing groove 208. At this time, the positioning block 306 inside the limit groove 209 controls the downward movement of the pressure plate 305 through the pressure rod 307, and the positioning block 306 will lock the positioning groove 303, thereby fixing the pull plate 301 to prevent the windproof cloth from being pulled out by the pull plate 301 at will, thereby protecting the windproof cloth.
