Detailed Description
As shown in figure 1, the novel construction method for installing the steel structure beam and column support is characterized in that: the method comprises the following steps: s1, mounting a bracket: firstly, an unmanned aerial vehicle is used for casting a 2.5mm nylon line to a station on a cableway along a cableway line, then a 3T winching is used for pulling a 6mm nylon rope connected with the tail end of the 2.5mm nylon line to the station along the cableway line at the station, and then the 6mm nylon rope is used for pulling the nylon rope to the station
The working steel wire rope is pulled to the upper station along the line, and the other side of the center line of the cableway is released in the same way
And working the steel wire rope. According to the landform of the cableway line, a simple herringbone support is manufactured at the position of the favorable support point by two-step building or on-site trees. Handle
After the working steel wire rope passes through the temporary roundabout wheel at the upper station, the working steel wire rope is braided and closed to form a circulating temporary traction rope, meanwhile, the temporary traction rope is hung into a rope supporting wheel groove of the simple support along the rope, and then the temporary traction rope passes through
Temporary pull rope handle
The working steel wire rope is pulled to a station to serve as a simple temporary goods rope bearing rope, the bearing rope is tensioned and fixed, and after a small sports car is hung, simple temporary goods rope installation is completed preliminarily.
The first formal cargo cable support is transported and installed from the lower station in sequence: the upright columns, the cross beams, the cable ropes and the like of the support are transferred from the centralized stockyard to a cargo cable loading point or the side of a road closest to the support point through a truck-mounted crane, and then are transported to a line through a simple temporary cargo cable.
S2, mounting a stand column: the first step is as follows: and selecting the position of the upright post and the cable wind rope ground anchor. According to the field conditions, the standing position of the upright post of the temporary cable support is determined by measuring through a total station, a wood plate (800mm multiplied by 50mm) or a steel plate (800mm multiplied by 10mm) is paved after leveling and tamping, and meanwhile, a proper natural anchor pile (a big tree or a whole rock with a proper shape) is selected as far as possible in the upper and lower station directions of the cross line of the upright post; under the condition of no natural ground anchor, a small-sized fully-buried ground anchor can be manufactured manually according to the stress of the guy rope to serve as an anchor pile of the guy rope; and under the condition that the periphery of the anchor pile is provided with rock without anchor points, only the anchor rod can be drilled on the rock to be used as an anchor pile of the guy rope. The second step is that: the upright post is installed by means of the slope terrain of the installation point, and the lower end of the upright post is fixed by a chain block for preventing the upright post from sliding downwards. And fixing four corresponding guy cables at the upper end of the upright post. The vertical column is slowly pulled up by the chain block in the lower station direction, and the other three guy cables are balanced in direction mastered by force. The third step: and hoisting the other upright post by using the erected upright post, and then repeating the second step. The fourth step: and the two upright posts are adjusted to proper positions by using the guy cables so as to facilitate the installation of the cross beam.
S3, beam mounting: and mounting a small holding pole at the top ends of the two upright posts which are completely stood as a lifting point of the chain block, and slowly lifting the cross beam. And after the beam flange is in place, the beam flange is fixedly connected with the column flange by using M24X80 high-strength bolts. And (5) removing the cable rope on the inner side of the door-shaped frame after the installation is finished.
S4, setting a cable rope: the standing angle of the portal frame is adjusted by 6 wind cables with the diameter of 15.5mm at the top of the portal frame to be perpendicular to the bearing rope as much as possible, and after the portal frame is adjusted, the wind cables of the ground anchor cables in 6 directions are tensioned and locked and fixed by a rope clamp, and then the 3T chain block is disassembled. The support higher than 15m is fixed by double-layer guy rope and waist rope.
