The invention discloses a high level bridge type suspended falsework with the top terminal suspended on the steel beam of the construction structure, consisting of a falsework frame, a fence, and a hanger. The falsework consists of a bottom frame, the upright columns of the fence at the two sides, and slanting steel wires; each fence consists of horizontal and vertical steel fence pipes and closely-knitted safety net, wherein the horizontal and vertical steel fence pipes are clamped with the upright columns of the fence to form a truss; the closely-knitted safety net is hung on the frame of the fence. One end of the slanting steel wire is connected with the top end of the upright columns of the fence, while the other end is connected with the bottom frame and the part of the connecting nodes of the vertical fence pipes. The bottom frame, the upright columns of the fence, and the steel fence pipes are connected by the slanting steel wires to form the truss. The hanger consists of a pulling wire and a pulling tool, wherein the two ends of the pulling wire are connected respectively with the beam and the falsework frame; one end of the pulling tool is connected fixedly with the steelbeam of the construction structure. The invention is convenient for high altitude construction, and has the advantages of highly reliable safety, light weight, convenient assembly and disassembly, etc.

The invention relates to a high-altitude long-span overhanging corridor type reinforced concrete structure and a construction method, wherein the corridor part is a stiff beam structure; with own bearing capacity of a profile steel, a beam template supporting system is a hung template supporting system in such a manner of fixing a square steel by means of a U-shaped screw and a nut; a floorslab is a self-supporting steel bar truss template which is welded to a pre-embedded steel plate on the stiff beam by means of a pin; and a steel platform is arranged on a corresponding floor at the lower part of the corridor as an operating and safety protection platform for template support construction. The high-altitude long-span overhanging corridor type reinforced concrete structure and the construction method have the advantages that: the template supporting construction method, according to which the operating platform is built from H-steel or profile steel beams, the stiff beam is hung and is self-supported and the floorslab is self-supported, is employed, so that the problem of difficult template supporting of the high-altitude long-span overhanging corridor structure, the revolving materials are greatly saved, the construction cost is reduced, the construction progress is accelerated and the safety is ensured; and the steel plate is pre-embedded on the stiff beam, so that the floor bearing plate is effectively connected with the stiff beam and the floor bearing plate and the stiff beam are capable of acting together to ensure the safety of the structure.

The invention discloses a high-altitude bulk process of a bolt ball net frame, comprising the steps: 1) erecting local scaffolds; 2) assembling square pyramidal units on the ground; 3) carrying out local assembly of the net frame on the local scaffolds and forming a net-frame start crossing unit; and 4) assembling the start crossing unit by adopting lifting equipment, wherein the lifting equipment is fixed to the start crossing unit; the square pyramidal units are lifted to high altitude by the lifting equipment and are symmetrically overhung, expanded and assembled from the middle of the net-frame start crossing unit to the two sides thereof till the assembly of the whole bolt ball net frame is finished. The high-altitude bulk process provided by the invention is applicable to installation and construction of various large-span bolt ball net frame roof structure systems; and according to the high-altitude bulk process, large construction machines are not needed, the operation is simpler, and only few supporting scaffolds need to be erected, thus greatly improving the labor efficiency and reducing the labor intensity.

The invention provides a pre-assembled leaching tank and an assembling method thereof. The pre-assembled leaching tank comprises a bottom plate section, a middle section and an upper part groove bodywhich are sequentially connected from bottom to top; the bottom plate section is of a cylindrical barrel structure with an opening formed in the top; a barrel wall is provided with a discharge hole pre-buried sleeve and a maintenance manhole pre-buried sleeve; a placing position of the discharge hole pre-buried sleeve is lower than a placing position of the maintenance manhole pre-buried sleeve; the middle section and the upper part groove body are both of a cylindrical barrel structure with openings formed in the top and bottom respectively; the barrel wall of the upper part groove body is provided with an overflow hole pre-buried sleeve and a feeding hole pre-buried sleeve; and a placing position of the overflow hole pre-buried sleeve is higher than a placing position of the feeding holepre-buried sleeve. The pre-assembled leaching tank is small in amount of required turnover material and rapid in construction period.

The invention relates to a method for installing a daylighting roof steel truss and a curtain wall in the air. The installed daylighting roof steel truss comprises a plurality of unit steel trusses, and every unit steel truss comprises a lower chord, an upper chord, a cross rod and a web member. The method comprises a first step of lifting the daylighting roof steel truss and hanging a safety net; a second step of utilizing the steel truss lower chords to serve as a supporting structure to erect a safety walkway and a construction operation platform; a third step of performing the first step and the second step in a line production mode; a fourth step of arranging double safety ropes or guardrails at the position of the safety walkway close to the edge, and installing the safety net; a fifth step of laying skirting boards on two sides of the safety walkway; a sixth step of installing a curtain wall glass frame; a seventh step of installing curtain wall glass; an eighth step of installing a drainage channel between the unit steel trusses where the curtain wall glass is installed well, enabling the drainage channel to have a certain gradient, arranging a water collecting tank at the tail end of the drainage channel, and enabling the water collecting tank to be communicated with a building drainage pipe.
