Abstract
The invention discloses a constructing method for a high-rise building elevator shaft through an elevating type safety protection steel platform, comprising the steps of: firstly, manufacturing a steel platform matched with the size of an elevator shaft, then installing the steel platform inside the bottom layer of the elevator shaft, carrying out elevator shaft construction operation by constructors standing on the steel platform, elevating the steel platform layer by layer after the construction on the current operation layer is completed until the steel platform is elevated to the elevator shaft of the upper floor to facilitate the elevator shaft construction operation, sealing the lower elevator shaft after the steel platform is elevated, and repeating the steps until the elevator shaft construction on all the floors of the whole building is completed. The construction method is featured by safety, simplicity and convenience for operation, easiness for construction, obvious economic benefits and the like, has the greatest advantages of saving lease expense of raw materials and facilitating cost control, and is particularly suitable for high-rise buildings and multistoried buildings with longer construction periods.
Description
Technical field
The present invention relates to a kind of construction techniques, particularly a kind of highrise building elevator shaft and duration be the security protection job practices of long multistory building elevator shaft.
Background technology
In the high-building construction process, the fall arrest of highrise building elevator shaft is the important checkpoint and the control point of safety management in the building operations.How guaranteeing the safe, economic of highrise building construction of lift well, is a quite great technical barrier.Construction is to set up from the end to the top with steel pipe scaffold in the elevator hoistways of general highrise building, and the constructor stands in and carries out the construction of lift well operation on the scaffold, and the wire rope off-load is used in the centre, and general 5 layers of off-load once.The shortcoming of this method is: owing to the mechanics bearing capacity of steel pipe self, when the support body height surpassed 50m, support body stability was insecure, and certain potential safety hazard is arranged (1).(2) generally the construction period of highrise building is longer, and steel pipe adopts lease more, and the holding time of tube material is longer, and the rent of steel pipe is bigger, is unfavorable for the saving of engineering cost.(3) it is cumbersome to set up scaffold, expends time in, and has prolonged the duration virtually.
Summary of the invention
The highrise building elevator shaft lift-type security protection steel platform construction method that provides a kind of safety good, simple to operate, good in economic efficiency is provided technical problem to be solved by this invention.
For solving the problems of the technologies described above technical scheme of the present invention: a kind of highrise building elevator shaft lift-type security protection steel platform construction method.Make a steel platform that matches with the elevator hoistways size earlier, then the steel platform is installed in the bottom elevator hoistways, the constructor stands on this steel platform and carries out the construction of lift well operation, treat successively to promote again after work layer construction finishes in the elevator hoistways of the supreme floor of steel platform and carry out the construction of lift well operation, and after promoting the steel platform, the lower elevator hoistway is sealed, until the construction of lift well of finishing whole all floors of building.
In the above-mentioned highrise building elevator shaft lift-type security protection steel platform construction method, described is after promoting the steel platform, in steel platform bottom every 3 layers at the floor levels face closure once with the sealing of lower elevator hoistway.
In the aforesaid highrise building elevator shaft lift-type security protection steel platform construction method, described is to set up steel pipe at elevator hoistways with the elevator hoistways sealing, and seals in surface layer shop template.
In the aforesaid highrise building elevator shaft lift-type security protection steel platform construction method, between between the edge of steel platform and the elevator hoistways inwall, be separated with a distance that the steel platform is freely risen.
Beneficial effect of the present invention: compared with prior art, the present invention adopts lift-type security protection steel platform to substitute traditional scaffold, needn't set up the lantern frame, only need the steel platform according to the prefabricated Steel section member of the fixed dimension of elevator shaft, the steel platform is easy to process, detachable.The steel platform can successively promote installation with tower crane along with the rising of agent structure, do not need as in the past successively set up scaffold or dismounting successively and mounting bracket, construction sequence and construction cost have been saved greatly, eliminated and set up the potential safety hazard that high-rise scaffold exists, have simple to operation, safe and practical characteristics, also save a large amount of expenses such as steel pipe lease, produced favorable economic benefit.And after adopting lift-type steel platform, the following cylindrical shell of steel platform does not need to set up the steel pipe frame sealing in the elevator shaft, only does common floor sealing every 3 layers at horizontal plane and gets final product, and can save the steel pipe rent, remarkable in economical benefits.Great advantage of the present invention is the rental charge that saves material, and is beneficial to cost control.The present invention a large amount of places that produce material of also can avoiding constructing take.During engineering construction, resident on every side and enterprises and institutions can normal life and work.Super close distance safety is passed through the success of high-rise resident's building, for later city underground engineering provides reliable decision-making foundation and technical indicator at the planning construction under the analogue, novel worker's law technology will promote the underground engineering construction technological progress, and social benefit and environmental benefit are obvious.Prove that through practice test characteristics such as safe, easy and simple to handle, easy construction that the present invention has, remarkable in economical benefits are particularly useful for the long multistory building of highrise building, construction period.

The specific embodiment
Embodiment 1.Shown in Fig. 1,2 or 3, first size according to construction work elevator shaft road ties with Luo and connects steel platform that matches with the elevator hoistways size of processing.Steel platform in this example adopts shaped steel and steel plate to tie to connect by Luo and forms.Then with tower crane with steel platform allocation and transportation to the job site, and cooperate and be installed in the bottom elevator hoistways, can freely rise for guaranteeing the steel platform, between between the edge of steel platform and the elevator hoistways inwall, be separated with a distance that the steel platform is freely risen.The constructor stands on this steel platform and carries out construction operation, after treating that the work layer construction finishes, with tower crane or electric hoist the steel platform successively is promoted in the elevator hoistways of a last floor and carries out the construction of lift well operation, until the construction of lift well of finishing whole all floors of building.The steel platform is along with after agent structure up promotes, in steel platform bottom every 3 layers at the floor levels face closure once, traditional sealing way is adopted in the sealing measure, promptly sets up steel pipe at the lower elevator hoistway, and seals in surface layer shop template.
Embodiments of the present invention are not limited to the foregoing description, and the various variations of making under the prerequisite that does not break away from aim of the present invention all belong within protection scope of the present invention.
