Detailed Description
The embodiment of the installation device for the large-span steel member is shown in the attached drawing 1, and comprises a support frame unit 1 installed according to a tower crane standard, wherein cross section steel 3 and sleepers 4 arranged on the section steel are arranged on the support frame unit 1; and a plurality of pull rods 2 are connected between every two adjacent support frame units 1 into a whole. A jack 5 is also included. The specification of the section steel is 300 multiplied by 12. The pull rod 2 is a steel pipe with the specification of phi 4.8 multiplied by 3.2, the vertical support frame unit 1 is integrally pulled every 2.5m high, and vertical and horizontal cross braces are arranged and are continuously arranged from bottom to top. The distance between the adjacent pull rods 2 is not more than 1.2 m.
The specific method in practice is as follows: 1. after the strength of the support foundation concrete reaches 100%, the support foundation concrete can be hoisted. 2. The temporary support frame is made of a tower crane standard section, is connected by original factory matched bolts, and is provided with pad steel □ 300 multiplied by 12 and sleepers on the standard section for adjusting elevation. The temporary support frame is formed by connecting phi 48 multiplied by 3.2 steel pipes and fasteners into a whole. The distance between the pull rods is not more than 1.2 m. The vertical supporting frames are pulled into a whole by phi 4.8 multiplied by 3.2 steel pipes every 2.5m, and vertical and horizontal cross braces are arranged continuously from bottom to top.
Application example: hoisting a large-span trestle bridge in the south open-air coal mine second-phase train loading system engineering with limited energy responsibility of the sinkiang sky pond.
The train loading system engineering of the south open pit coal mine of the energy source of the Tianchi of Xinjiang, a main structure steel structure main body. Which comprises the following steps: 375. 376, newly building a transfer station; 377 belt conveyor trestle tightening room; 377 belt conveyor drive; 377 belt conveyor drive room to train loading station trestle; train loading station. Wherein, the 377 tensioning space to the driving tensioning space is a high-span trestle with a span of 50m and a height of 8 to 15 m. Four belt conveyors with different sizes cross in the area. By combining the engineering structure form, a scheme of sectional hoisting is planned according to the actual situation of the site and the whole construction schedule.
The trestle steel truss is divided into two sections, and a temporary support is arranged in the middle of the trestle steel truss and serves as a temporary support for two sections of hoisting. The trestle steel truss is divided into two sections, wherein the total weight of the trestle steel truss is 50 tons (about 48.5 tons calculated according to 50 tons after purlines and bottom steel plates are removed), a fixed support joint (the side between tensioning) is placed on a temporary vertical support frame, the length of the fixed support joint is 25m +2.7m =27.7m, 100% of the fixed support joint is disconnected at the node, namely the connecting plate at the node is enlarged at the moment, the length and the width of the connecting plate are increased by 40mm, and then the fixed support joint and the fixed support joint are. The sliding support section (the side of the driving room) is 25m-2.7m =22.3m, the QAY260 automobile crane is adopted to be in the air and is butted with the fixed support section, and the installation welding seam is adopted for splicing on site. A QAY260 all-terrain crane (260-ton truck crane) is adopted for hoisting, and through field investigation, the hoisting radius of the side close to the tensioning room is 22m, and the hoisting radius of the side close to the driving room is 18 m. The two sections are respectively assembled and formed within the range of the turning radius of the crane, so that secondary transportation is avoided. The temporary support is made of QTZ40 tower crane standard knot, and the standard knot is covered by the cushion steel □ 300X 12 and the sleeper for adjusting the elevation.
By adopting the device, the normal production of the original factory is ensured, the technical reconstruction and extension engineering construction is normally and continuously carried out, and no safety accident occurs, so that the device is praised by owners and supervisors.
