Abstract

The present invention is a kind of blocking partition adding type lift installation method of net rack, mainly comprises the steps: the first step, according to the rack longitudinal length rack is divided into several rack machining cells; In second step, net rack blocks is made in assembling on ground; In the 3rd step, sling at net rack blocks both sides installation lifting gear and with net rack blocks; In the 4th step, add grid respectively along the net rack blocks both sides; The 5th goes on foot, and connects the rod member between each rack machining cell in the high-altitude; The present invention has significantly reduced amount of high-altitude operation because most of operations can be finished on ground, and is safe and reliable, easy construction, and the construction quality height greatly reduces engineering cost simultaneously, has improved economic benefit.

Description

Blocking partition adding type lift installation method of net rack

(1) technical field:

The present invention relates to a kind of construction techniques, specifically is a kind of blocking partition adding type lift installation method of net rack.

(2) background technology:

At present, domestic rack install adopt the high-altitude sliding method,, high altitude bulk method, whole lift method.

1, high-altitude sliding method: promptly adopt the slide rail of laying in advance, set up and movably assemble the fetal membrane frame.Unit truss assembly unit is good with pulling equipment moves to the installation site.

Its shortcoming: higher to the construction plant conditional request, because of directive wheel walking deflection easily causes installing the rack journal offset.Design of net shell-type scaffold and sliding rail basis thereof once have high input, and construction cost is higher.The work high above the ground unit is installed, and security risk is bigger.

2, high altitude bulk method: promptly adopt steel pipe scaffold to set up full hall rack assembly unit fetal membrane, the constructor carries out the rack installation on the fetal membrane frame.

Its shortcoming: though this method does not need large lifting equipment, the working security height need take a large amount of circulation materials, and shelf to take the amount of tearing open big, the construction operation phase is long, its rack welding quality is difficult for guaranteeing.

3, integral installation method: rack becomes whole at installation on ground, with crane gear its integral body is risen to design attitude then and is fixed.

Its shortcoming: though do not need tall and big assembling support, work high above the ground is few, easily guarantees welding quality.But the rack overall weight is big, need select the big equipment of lifting capacity for use, and technical sophistication.If adopt poly-machine lifting crane, rack is subject to turn round and weld cracking, and construction cost is higher.

(3) summary of the invention:

Purpose of the present invention proposes a kind of large-scale hoisting machinery that need not exactly, and most of assembling operation can be finished on ground, and engineering cost is low, safe and reliable blocking partition adding type lift installation method of net rack.

Blocking partition adding type lift installation method of net rack, it is characterized in that comprising the steps: the first step, according to whole rack longitudinal length and used lifting gear lifting ability rack is divided into several rack machining cells, and determines the Pin number of single rack that each machining cell comprises; In second step, make the net rack blocks that the part rack by the single racks of described some Pin is constituted in ground assembling; In the 3rd step, sling at net rack blocks both sides installation lifting gear and with net rack blocks; The 4th step, add grid respectively along the net rack blocks both sides, every interpolation one lattice to two side shifting lifting gear once, promptly promote a grid height, have added all until promoting, and this rack machining cell is seated on the bearing; The 5th step repeated second to FOUR EASY STEPS, finished the making of several rack machining cells one by one, connected the rod member between each rack machining cell then in the high-altitude, promptly made whole rack.

Described lifting gear adopts the mast crane gear.

The assembling making step of described net rack blocks is: a. at the part lower edge of the single rack of installation on ground the one Pin, uprightly and with steel pipe withstands the lower edge ball with lower edge earlier then; B. comply with upright successively the 2nd Pin of quadrat method, the 3rd Pin ... single rack part lower edge, connect the vertical rod member between every Pin, prefabricated quadrangular pyramid in advance is installed then; C. weld winding up of the single rack of every Pin, and connect wind up between every Pin horizontal and vertical rod member, promptly.

The present invention has absorbed the more advanced CONTROLLED INTEGRAL LIFT TECHNOLOGY that present domestic rack construction is adopted, sliding technology, different is to need not large-scale hoisting machinery, but hangs hoisted in position by mast lifting gear and kart, and rack welding and assembly unit are all finished on ground.Therefore, compared with prior art, more can guarantee welding quality, significantly reduce amount of high-altitude operation, safe and reliable, easy construction, machinery expenses is low, greatly reduces engineering cost, has improved economic benefit.

(5) specific embodiment:

Embodiment: with 180 meters of longitudinal lengths, 90 meters of spans, high 31 meters indoor coal storage yard rack processing and fabricating is that example describes, referring to accompanying drawing, among the figure, 1-net rack blocks part, 2-adds rack part, 3-lower edge, the 4-steel pipe, 5-lower edge ball, the 6-quadrangular pyramid, 7-winds up, the 8-mast, the 9-cable wind rope, 10-adds grid, 11-bearing, the single rack of 12-the one Pin, the single rack of 13-the 2nd Pin, the single rack of 14-the 3rd Pin, the single rack of 15-the 4th Pin, the single rack of 16-the 5th Pin, the single rack of 17-the 6th Pin.The first step, according to the vertical 180 meters length of rack and the lifting ability (hoist engine 20T, crane 16T) of employed mast lifting gear, this rack is divided into five rack machining cells to be processed respectively, long 36 meters of each rack machining cell, comprise the single rack of 6 Pin, 6 meters of every Pin longitudinal lengths, the rack part 2 that each rack machining cell is added in both sides one by one by the net rack blocks part 1 that forms at installation on ground and the back of slinging constitutes, referring to Fig. 1.Second step, earlier make the net rack blocks that the part rack by the single rack of 6 Pin is constituted in the ground assembling, its concrete steps comprise: a. elder generation is at the part lower edge 3 of the single rack 12 of installation on ground the one Pin, then that lower edge is upright, as shown in Figure 2, and withstand lower edge ball 5 with steel pipe 4 and prevent that the rack downwarp from launching; B. with the lower edge of the single rack of upright the 2nd Pin of quadrat method, the 3rd Pin, the 4th Pin, the 5th Pin, the 6th Pin (numbering is followed successively by 13,14,15,16,17), connect the vertical rod member between every Pin, prefabricated quadrangular pyramid 6 in advance is installed then, as shown in Figure 3; That c. welds the single rack of every Pin winds up 7, and connects wind up between every Pin horizontal and vertical rod member, promptly is assembled into net rack blocks 1, with reference to figure 4; The 3rd step, four masts 8 are installed altogether in the net rack blocks both sides, referring to Fig. 5, Fig. 6, mast is made by δ 235 * 12 seamless steel pipes, and every mast tiltedly draws four road cable wind ropes 9, and the elevator poplar is adopted 20T, assembly pulley adopts 4 * 4, be aided with the 16T crane when mast moves, net rack blocks is sling, general height of lift is advisable for overhead about 2.5 meters with the net rack blocks both sides; The 4th step, add grid 10 respectively simultaneously along the net rack blocks both sides, every interpolation one lattice to the both sides movable mast once, promptly promote a grid height, have added whole grids until promoting, and more whole rack machining cell are seated on the bearing 11, as shown in fig. 1; The 5th step repeated aforementioned four steps and finished five unit trusses that constitute this indoor coal storage yard rack one by one, connected the rod member between these five unit trusses then in the high-altitude, promptly made whole rack.
