Abstract
A kind of installation method for the platform high-altitude floor that is widened, including step：1) several escape ways are made, each escape way includes bottom plate and the fence mounted on bottom plate both sides, the length direction of bottom plate upper edge escape way is welded with several lateral steps, the side that two fences are not connect with bottom plate is equidistantly welded with several railings, and the both ends of escape way are connected separately with top hook and bottom hook；2) escape way is sling using truck crane, top is hooked on to the tripod top for having installed cone section, bottom, which is hooked on, has installed in broadening platform outboard structure；3) remaining escape way is equidistantly uniformly installed along the circumferencial direction of cone section using the method in step 2)；4) it is manually entered in escape way, hand steered fence is climbed to escape way, and the high-altitude floor for the platform that is widened is installed.Construction efficiency of the present invention is high, easy to operate, can effectively ensure that the safety of construction personnel, and after construction, fully meets the requirement of floor construction quality.
Description
Technical field
The present invention relates to steel construction indirect cool tower construction fields, are especially the platform high-altitude that is widened in a kind of steel construction indirect cool tower
The installation method of floor.
Background technology
The structure type and size of the steel construction indirect cool tower of our company's hot work in progress are as follows：Tower height 170m, tower outlet are outer
Diameter 84m, tower exit inside diameter 82m, tower bottom diameter 129.44m, cone section height 55m；Total 18 layers of number of plies, comprising 5 layers of cone section and
13 layers of straight section bore and one layer of broadening platform, every layer of each 36 triangle component are equipped between section and straight section；Reinforcing ring quantity accounts for 3 layers, position
Put respectively 90.08m, 125.16m, 160.23m, in the reinforcing ring at middle part, most heavy triangle component weighs about 4000kg.
Peripheral protective aluminium sheet is started setting up from the 4th layer of cone section, after arranging peripheral protective aluminium sheet entirely on the platform that is widened, single component weight
It measures as 9908kg；The stage+module absolute altitude that is widened is 35.95m, and lower support is arranged in 13.09m, and be widened platform structure and ground-angle
It is 29.6 °.
In the floor in installing above-mentioned broadening platform, no existing construction technology can refer to, therefore, in order to ensure that broadening is flat
The safe construction of floor and raising operating efficiency in platform, need to design a set of completely new arrangement and method for construction to complete broadening platform ribs
The installation of plate is fixed.
Invention content
The technical problem to be solved by the present invention is to provide a kind of installation method for the platform high-altitude floor that is widened, construction effect
Rate is high, can effectively ensure that the safety of construction personnel.
The technical solution of the present invention is to provide a kind of installation method for the platform high-altitude floor that is widened, including walking as follows
Suddenly：
1) several escape ways are made, each escape way includes bottom plate and the fence mounted on bottom plate both sides, bottom plate
The length direction of upper edge escape way is welded with several lateral steps, and the side that two fences are not connect with bottom plate is equidistantly welded
There are several railings, the both ends of escape way are connected separately with top hook and bottom hook；
2) escape way is sling using 25 tons of truck cranes, top is hooked on to the tripod top for having installed cone section,
Bottom, which is hooked on, has installed in broadening platform outboard structure；
3) remaining escape way is equidistantly uniformly installed along the circumferencial direction of cone section using the method in step 2)；
4) it is manually entered in escape way, hand steered fence is climbed to escape way, to the high-altitude floor for the platform that is widened
It is installed.
After more than structure, compared with prior art, the installation method of present invention broadening platform high-altitude floor have with
Lower advantage：Then several escape ways are surrounded cone section by the present invention by making several escape ways in advance by truck crane
Circumference is equidistantly uniformly installed, and the hand steered fence of construction personnel is finally allowed to be climbed to escape way, to the high-altitude for the platform that is widened
Floor is installed；Due to escape way include bottom plate and the fence mounted on bottom plate both sides, and two fences not with bottom plate
The side of connection is equidistantly welded with several railings, and therefore, construction worker can be very safe in channel；The setting of escape way
The frequency of use of big machinery is eliminated, and then has saved great amount of cost；Construction worker can be flexibly movable in channel, improves
The convenience of operation, and then construction efficiency is accelerated, and after construction, it is fully able to the requirement for meeting floor construction quality.
Description of the drawings
Fig. 1 is the structure diagram of escape way in the present invention.
Specific embodiment
The installation method of present invention broadening platform high-altitude floor is made with reference to the accompanying drawings and detailed description further
It is described in detail：
As shown in Figure 1, in this embodiment, a kind of installation method for the platform high-altitude floor that is widened of the present invention, packet
Include following steps：
1) several escape ways are made, each escape way includes bottom plate 13 and the fence mounted on 13 both sides of bottom plate
14, the length direction of 13 upper edge escape way of bottom plate is welded with several lateral steps 12, and two fences 14 are not connect with bottom plate 13
Side be equidistantly welded with several railings 11, the both ends of escape way are connected separately with top hook 15 and bottom hook 10；
2) escape way is sling using 25 tons of truck cranes, top hook 15 is hooked on the tripod for having installed cone section
Portion, bottom hook 10, which is hooked on, have been installed in broadening platform outboard structure；
3) remaining escape way is equidistantly uniformly installed along the circumferencial direction of cone section using the method in step 2)；
4) it is manually entered in escape way, hand steered fence 14 is climbed to escape way, to the high-altitude rib for the platform that is widened
Plate is installed.
Then several escape ways are surrounded cone section by the present invention by making several escape ways in advance by truck crane
Circumference is equidistantly uniformly installed, and the hand steered fence of construction personnel is finally allowed to be climbed to escape way, to the high-altitude for the platform that is widened
Floor is installed；Due to escape way include bottom plate and the fence mounted on bottom plate both sides, and two fences not with bottom plate
The side of connection is equidistantly welded with several railings, and therefore, construction worker can be very safe in channel；The setting of escape way
The frequency of use of big machinery is eliminated, and then has saved great amount of cost；Construction worker can be flexibly movable in channel, improves
The convenience of operation, and then construction efficiency is accelerated, and after construction, it is fully able to the requirement for meeting floor construction quality.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
It encloses and is defined, under the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art are to the technical side of the present invention
The various modifications and improvement that case is made, should all fall within the scope of protection of the present invention.
