Embodiment

[0011] (1) The steel column structure installation of the main factory building of Pugang Luojing Relocation Project adopts the installation method of the adjustable flat pad. Each steel column uses 12 sets of adjustable flat pads, and the flat pad is 120×240 × 20mm, 4 sets of adjusting nuts and screws are M12 × 50; K, J, H series workshops have a total of 45 steel columns, directly saving economic costs: 45 × 12 × 53 yuan = 28620 yuan.

[0012] (2) For the installation of various structural equipment in the second-step Luojing project of Pudong Iron and Steel Co., Ltd., the adjustable seat slurry installation method of this flat backing plate is adopted. A total of 400 sets of flat backing plates are used, and the size of the flat backing plate is 120×240×20mm. 4 sets of adjusting nuts and screw rods are M12×50; directly save economic costs: 400×53 yuan=21200 yuan.

[0013] Fees are calculated based on:

[0014] ①. To install the structure or equipment using the traditional ...

Abstract

The invention relates to a flat shim plate-adjustable grouting installation method, belonging to a method for installing a steel column or a device. The method comprises the following steps: symmetrically welding rectangular plates with holes on the back and forth of the left side and the right side of a flat shim plate at intervals; cutting a grouting pit outside the foundation bolt or the preset hole of the concrete foundation of an installation device; arranging four screw holes which are arranged into a rectangle in the grouting pit; correspondingly and vertically plugging four screws the upper ends of which are respectively screwed with a regulating nut into the four screw holes; correspondingly sheathing the holes on the four rectangular plates of the flat shim plate onto the four screw in a penetrating mode so that the flat shim plate is supported on the regulating nuts; utilizing the regulating nuts to regulate the scale height and the levelness of the flat shim plate; leveling the flat shim plate for the fist time, arranging a grouting box on the foundation surface at the periphery of the grouting pit and placing a grouting material into the grouting box; when the grouting material is prehardened, utilizing the regulating nuts to accurately level the flat shim plate so that both the scale height and the levelness of the flat shim plate reach the installation requirements. When the steel column or the device is installed, an inclined shim plate is not needed for leveling, thus the method is convenient and speedy.

Description

technical field [0001] The invention belongs to a method for installing a steel column and equipment, in particular to a method for installing a seat slurry for a steel column and equipment. Background technique [0002] At present, in the installation of steel structure columns and equipment, the installation method of seat grout is often used, and the seat grout is usually placed on the foundation bolts or reserved anchor bolts on the concrete foundation for installing steel structure columns and equipment Cut out a slurry pit on both sides of the hole, place a slurry box made of wood formwork or thin iron sheet on the slurry pit, put the slurry in the slurry box, place a flat pad on the slurry, and pass the measurement To control the elevation of the flat pad. This method takes a long time to seat the grout, and the elevation and levelness of the flat backing plate are greatly affected by the seat slurry, so it is difficult to control accurately. The inclined backing pl...
