The specific embodiment
In figure, this lattice column comprises the support lattice column 1 being fixed in column castinplace pile, it is fixing with disassembling tool type lattice column 2 that this support lattice column 1 is provided with lifting, lifting is fixing is provided with the first flange steel plate 3 with disassembling tool type lattice column 2 tops, lifting is fixing is provided with the second flange steel plate 4 with disassembling tool type lattice column 2 bottoms, support lattice column 1 top is provided with between three-flange steel plate 5, the first flange steel plates 3, the second flange steel plate 4 and three-flange steel plate 5 and adopts screw rod 6 to connect.
Carrying out, a roof fall is low when darker, in order to guarantee that lattice column is disassembled into power, reuses and cuts the waste, and difficulty of construction has increased a lot; The preparation of disassembling tool type lattice column, with supporting the assembled of lattice column, the construction control such as lattice column integral hoisting Strength and stability, lattice column installation verticality, absolute altitude, direction are very difficult with engineering.Therefore produce following imagination:
(1) establish from supporting lattice column end face absolute altitude to concrete terrace, the lattice column that lifting fixed support lattice column is used and ground are shelved above fixing and are proofreaied and correct the lattice column needing, fixing with disassembling tool type lattice column for lifting;
(2) according to this imagination, lattice column is divided into two parts and forms, take and design that to support lattice capital absolute altitude be boundary; The support lattice column that the following part lattice column of absolute altitude is used for design propping works, inserts and is fixed in column castinplace pile; The above part lattice column of absolute altitude is configured to lift fixing with disassembling tool type lattice column, reuses;
(3) when construction, need connecting portion to adopt flange Plate Welding disassembling tool type lattice column bottom, will support lattice column end face needs connecting portion also to adopt flange Plate Welding; And in lattice column, weld 4 and locate angle steel, then with long bolt, make silk mouth and be spliced into whole lattice column, and long bolt must be connected and the certain altitude that elevates above the soil, when concrete has watered and reach concrete initial set, become flexible and exit screw rod, as do not become flexible disengagement, cutting open, will lift up and down fixing with disassembling tool type lattice column and support lattice column and the disengagement of instrument lattice column, the lifting that hangs out upper part with crane is fixing with disassembling tool type lattice column, reaches the function of disassembling tool type lattice column.
Therefore, according to one embodiment of present invention, a kind of disassembling tool type lattice column, it is characterized in that this lattice column comprises the support lattice column 1 being fixed in column castinplace pile, it is fixing with disassembling tool type lattice column 2 that this support lattice column is provided with lifting, lifting is fixing is provided with the first flange steel plate 3 with disassembling tool type lattice column 2 tops, lifting is fixing is provided with the second flange steel plate 4 with disassembling tool type lattice column 2 bottoms, support lattice column 1 top and be provided with three-flange steel plate 5, the first flange steel plate 3, between the second flange steel plate 4 and three-flange steel plate 5, adopt screw rod 6 to connect.Wherein lifting is fixing with the same lattice column 1 that supports of disassembling tool type lattice column 2 overall dimensions.
Its construction method is as follows:
A, support lattice column 1 and lifting is fixing with disassembling tool type lattice column 2, all adopts outer processing, enter behind scene and to be spliced into integral body splicing on platform 7.
B, 4 diameter 25mm screw rods 6 of disassembling tool type lattice column surrounding configuration, the certain altitude that elevates above the soil, the long all about 75mm of 6 liang of captacula teeth of screw rod.Screw rod 6 fixing is down worn with disassembling tool type lattice column 2 capitals from lifting, the 3rd screw of sending out steel plate 5 blue that pierces into that support lattice column 1 welded.
C, splicing platform 7 on, screw rod 6 by lift fixing with disassembling tool type lattice column 2, through first of a thick 20mm of end face, send out steel plate blue wear tooth screw ¢ 30, downward the first flange steel plate 3 by thick 20mm and the second flange steel plate 4 wear tooth screw ¢ 30.
D, screw rod 6 are tightened and are supported the double nut 8 that lattice column three-flange steel plate 5 bottoms have welded to next thread, screw rod 6 tightens a nut 9 at a upwards thread on tool-type lattice column the first flange steel plate 3 tops, being assembled into whole joint lattice column, to make levelling vertical with school, and do temporary fixedly, through checking size, mark elevation control line.
E, after meeting the requirements, start to lift, adopt 3, crane to hang, after aerial Hui Zhi, hang head, after lifting is fixed and hung with whole lattice column 2, lifting is fixing with disassembling tool type lattice column 2 certain altitude that bassets, and must survey accurate support lattice column capital design elevation with level gauge.
When F, the concrete strength of smashing to be poured reach initial set, with the loosening nut of track wrench and long bolt, as do not become flexible disengagement, cut off screw rod, then with crane, hang out lifting fixing with disassembling tool type lattice column 2.
After pulling down, this lifts the fixing fastness with disassembling tool type lattice column and verticality etc. on inspection, and after meeting the requirements, front step repeats in other stand column pile, to carry out lattice column lifting like this, meets disassembling tool type lattice column use function.
Control and require: scene arranges splicing platform, verticality and the level of with transit and level gauge, proofreading and correct splicing platform, to guarantee that platform meets the requirements.Then on platform, eject the reference line of controlling lattice column, to guarantee to splice the verticality of rear lattice column.With crane, respectively the assembled support lattice column of need is winched on platform with disassembling tool type lattice column with lifting is fixing, with long bolt, upper and lower two parts are stitched together, and with spirit level, proofread and correct the lattice column having spliced, whole joint should be made, be welded, be assembled into lower partitive case structure post.
For preventing the stressed excessive generation distortion at bolt position after lifting, lattice column and lifting are fixing to be connected with electric welding with the stitching portion of disassembling tool type lattice column temporarily supporting, in hanging process lattice column vertically after, with gas welding, reject.Adopting crane to lift by crane whole joint lattice column need configure fringed iris herb, arrange suspension centre etc. by actual conditions, guarantees not flexural deformation.When stand column pile pore-forming finishes, gaging hole completes, after qualified examination, with crane, hang filling pile cage of reinforcement and lattice column is assigned.
