Description
Technical field
The present invention relates to technical field of building construction, specifically, being a kind of work China Democratic National Construction Association factory building roof system installation process
Used in the installation of large span latticed shell structure roofing with moving type security net hang method.
Background technique
With continuing to increase for national energy-saving environmental protection dynamics, the outdoor material storage yard of metallurgy, coal, power industry will be adopted gradually
It is closed with rack greenhouse form, reduces raw material loss and fugitive dust.Material storage yard is mostly large span and length is long, inside there is large-scale feeding
Etc. equipment, therefore the height that need to build of rack greenhouse and span it is big.This just makes that roofing tile construction brings difficulty and dangerous property coefficient is big
Increase.It, need to be in greenhouse reticulated shell for the safety for guaranteeing reticulated shell roofing tile construction personnel when greenhouse reticulated shell roofing color steel tile goes along with sb. to guard him construction
Backspin adds safety devices.
Currently, longspan structure is more and more widely used in all kinds of buildings in the realm of building construction.It is constructing
In the process, scaffold need to be usually set up below longspan structure or completely paving safety net provides safe operation for operating personnel
Space.However, the safety protecting method of these traditional longspan structures is required to a large amount of artificial and material of investment, and need
Longer construction period is wanted, higher cost is caused.
There are biggish security risks in large span grid structure roofing installation process, for the generation one for avoiding high pendant accident
As require to hang safety net in operating area, especially roofing height is higher, the biggish roofing of span, the extension of safety net
Roofing construction efficiency is influenced due to taking a lot of work if process all compares, is time-consuming, and can not move after safety net is completely spread.
Therefore known large span latticed shell structure roofing installing engineering there are problems that it is above-mentioned various inconvenient and.
Summary of the invention
The purpose of the present invention is to propose that one kind convenient can be installed, and reduces worker's installation strength, improves security performance,
It eliminates safe hidden trouble, and the large span latticed shell structure roofing installation that can be reused hangs method with moving type security net.
To achieve the above object, the technical solution of the invention is as follows:
A kind of large span latticed shell structure roofing installation hangs method with moving type security net, reticulated shell length 120m, reticulated shell across
Degree is 112m, and sagitta 47m, roofing enclosure is using color steel plate, it is characterised in that the following steps are included:
A, steel ladder is made
Several steel ladders are made, the long 8300mm of steel ladder makes two sides handrail with diameter 25mm coating steel pipe and two sides are helped
Pedal stroke between bar, one end of steel ladder, which is equipped with, hooks elbow；
B, fixed wirerope and carrying cable are set
The segmental arc from the maximum of reticulated shell both ends is left ground 12m or more and is started, construction personnel is using steel ladder in reticulated shell knot
Several fixed wireropes and several carrying cables, fixed wirerope and traction is fixedly installed to the latticed shell structure lower boom at both ends in structure length
Wirerope is spaced apart from each other arrangement, and fixed wirerope and carrying cable use 14mm wirerope；Fixed wirerope is fixed on steel cable clamp
On latticed shell structure lower boom, without intermediate fixed point in 120m reticulated shell length, carrying cable waits for twining by pulley blocks carrying cable
Cooperate around ground and hoist engine；Fixed wirerope and carrying cable use the rope made of hemp and ground staff that construction personnel puts down in reticulated shell
Cooperation, has bundled wirerope with the rope made of hemp, is pulled by construction personnel in reticulated shell to reticulated shell lower boom and is fixed；
C, production, erection safety net
Safety net is made, safety net uses every 6m × 9m specification, and it is whole to be combined into a laying width 12m；Safety
The suspension of net and fixing means are as follows: installation personnel reaches each fixed wirerope hitch point by steel ladder, using the rope made of hemp safety net
It pulls installation fixing position to set, safety net is suspended under fixed wirerope by U-shaped shackle, and shackle needs reasonable Arrangement, safety net
It can be moved freely by shackle；On the top of carrying cable, binding uses steel wire lashing for safety net binding, and binding point needs reasonable cloth
It sets and binds securely, whens safety net binding and fixing will distinguish advance or retreat wirerope, have to binding and fixing in advance wirerope
On；
D, several hoist engines are arranged in ground
Pulley is respectively set at the both ends of large span latticed shell structure, pulley is hooked on latticed shell structure lower boom, and composition is slided
Wheel group；It is set to the starting point of installation roof color steel plate in one end of large span latticed shell structure, in the another of large span latticed shell structure
The lower section ground at end is arranged and fixes several hoist engines, and one hoist engine of a carrying cable and setting cooperates, carrying cable
Wirerope be wound on hoist engine by pulley blocks, all elevator machine circuits are connected, and are passed through motor switch and are carried out
Control keeps sync pulling；Hoist engine starting drives the wirerope for leading carrying cable to advance, while also driving safety net to Forward
It is dynamic, it realizes and is moved forward with the construction speed of roofing color steel tile.
Large span latticed shell structure roofing installation of the invention with moving type security net hang method can also use it is below
Technical measures further realize.
Method above-mentioned, if fixed wirerope cannot tense, among fixed wirerope wherein the fixed wirerope is since span is big
Downwarp spend greatly, about 60m increases fixed point at one among fixed wirerope, it is ensured that amount of deflection is no more than 2.0m under wirerope maximum.
Method above-mentioned, wherein the hoist engine is electrical hoist, tractive force 1t.
After adopting the above technical scheme, the large span latticed shell structure roofing installation of the invention moving type security net side of hanging
Method has the advantage that
1, moving type security net apparatus structure is simple, easy to make；
