Description
Technical Field
The invention belongs to the field of scaffolds, and particularly relates to a use method for building a large-space curved surface top by a self-made track mobile scaffold.
Background
With the diversified development of the building form and function in China, the structural theory is gradually improved, the construction technology is continuously improved and updated, the yield of the steel is rapidly increased in China since the century, the steel is encouraged by national policies, the steel structure building is actively developed, and a large number of high-altitude large-span steel structure buildings are developed domestically, so that the high-altitude large-span structures such as net racks, net shells, pipe trusses, large-area ceiling decorations and the like are rapidly developed and are widely applied to public buildings such as airports, large-scale stations, exhibition halls, stadiums, large-scale retail and wholesale supermarkets and the like.
Compared with the common indoor decoration engineering, special construction methods are needed to finish the high-altitude large-span engineering, particularly the suspended ceiling decoration engineering. The steel net rack or the suspended ceiling of the large public building is generally 10-30 m in installation height, large in construction area and high in height. Meanwhile, in order to ensure the decorative effect of beautiful atmosphere, the shapes of the decorative plates are generally single-curved or double-curved surfaces. Therefore, the difficulties in the construction process are mainly concentrated on: firstly, the installation height is high, and the difficulty of ensuring safety is high; secondly, the unit plates are complex to splice, the difficulty of positioning and mounting is increased due to the complex curved surface modeling, and the construction period is prolonged; thirdly, due to the limitation that large-area construction occupies a field, other sub-project projects are difficult to implement simultaneously, the construction efficiency of the whole project is affected, and the requirement of the construction period cannot be met.
In the prior art, common construction methods include a full-space overhead bulk loading method, an overhead sliding method, a block hoisting method, an integral hoisting method and the like, but the economy and the construction period cannot be both considered.
The full-space overhead bulk assembly method is a method for directly and totally assembling small assembly units or parts at a design position, and comprises a full-space scaffold and an overhanging scaffold. The full framing scaffold is mainly used for assembling parts, and the overhanging framing scaffold is mainly used for assembling small assembling units at high altitude or assembling spherical reticulated shell triangular grids. The method has the advantages of large scaffold consumption, high labor consumption, repeated assembly and disassembly, high labor intensity and long construction period.
The high-altitude sliding method is an installation method that the net rack or the suspended ceiling unit slides to a designed position on a preset slide rail (the middle or two ends of a building) to be spliced into a whole. The method has no influence on the internal construction of the building, and the top installation and the lower construction can be operated in parallel and in a three-dimensional way. But simultaneously, it requires great to track below support rigidity, and slide and draw gear need lead to long setting, and the expense is higher, and the design of traction force and traction speed and the precision of synchro control are difficult to grasp also. In addition, potential safety work hazards at high altitude exist, and safety protection is difficult.
The block hoisting method is that the net rack or the suspended ceiling is divided into a plurality of units, the units are assembled at corresponding ground projection positions respectively, then the units are hoisted to installation positions by utilizing hoisting equipment, and two adjacent units are butted at high altitude. The installation method has the advantages of less manual high-altitude operation and economy, but the installation precision is difficult to control, the technical problem of aerial displacement needs to be solved, and the requirement on hoisting machinery is higher. In addition, the whole civil structure is constructed, and the field space limitation also has great influence on the model selection of the hoisting machinery.
The integral lifting method is that the net rack or the suspended ceiling is completely assembled on the ground or the platform, and is vertically or horizontally lifted and transported to an installation position by using a lifting machine, and finally, the net rack or the suspended ceiling is adjusted and fixed. The integral assembly needs a large enough assembly field and a hoisting mechanical hoisting field. The higher the hoisting height, the larger the turning radius and the heavier the hoisting weight, the greater the construction difficulty.
In recent years, China has made high requirements on the safety of high-altitude construction, and the construction method of integral hoisting is not basically allowed.
Therefore, in order to determine the construction method of the high-altitude large-span suspended ceiling decoration project according to local conditions by combining construction technical conditions and equipment resources under the condition of meeting the quality, safety, construction period progress and economic benefits, the construction method of the large-scale complex suspended ceiling project, namely the self-made rail type mobile scaffold construction method, which has the advantages of simple structure, convenience and quickness in construction and economy and reasonableness, is provided. When the construction mode of the movable scaffold is adopted, the scaffold frame body material in one unit area only needs to be put into in unit time, and the required manpower and machines for assembling one unit can be met, so that the net rack or the suspended ceiling in the construction area which is several times or even dozens of times can be completed. The construction speed is fast, and occupation space is not taken, and other civil engineering works can be alternately constructed.

The guide rail installation accuracy, it is big to remove scaffold frame dead weight load, need move on special guide rail during the removal, and the installation accuracy of guide rail requires highly, bears the load greatly, needs level and straighten.
The deformation of the movable scaffold is mainly controlled by the following three points: the whole frame body sinks due to the foundation settlement; the whole downwarping is generated due to the upper structure and construction load; the support part is assembled to the structure and the local downwarping of support body that produces because of the dead weight. The former two kinds of deformations are generally less, and the first kind can be solved when the support body design with bottom basis is handled, and the second kind accessible is to removing scaffold platform base arch camber in advance and eliminate partial whole downwarping volume. The third deformation also has influence on the construction precision of the suspended ceiling because of uneven distribution position and deformation size. Because the load at the supporting point is transmitted to the cross rod firstly and then to the vertical rod, the inclined supporting rod is additionally arranged below the supporting point of the cross rod, so that the load is transmitted to the vertical rod, and the deformation of the supporting point is eliminated.
The traction of the movable scaffold is completed after one span of the suspended ceiling, the movable steel pipe scaffold is pulled by the slow electric winch and the steel wire rope to the position below the next span of the suspended ceiling, and the movable steel pipe scaffold is possibly stressed unevenly during traction, so that the scaffold is caused to generate large deformation.
(1) After the installation of the one-span suspended ceiling is completed, the movable scaffold needs to be pulled and moved to the lower part of the next-span suspended ceiling.
(2) The traction adopts a slow electric winch to be arranged in front of the middle rail of the movable scaffold, the distance from the scaffold is greater than the width of one span, and the traction is slowly carried out to the lower part of the next span.
(3) After the moving is finished, the side of the four castors is welded with a stop iron sheet to prevent the moving scaffold from sliding.
The height change of the movable scaffold, the suspended ceiling is a complex curved surface and is not of a horizontal structure, so that the height of the movable scaffold body is adjusted along with the construction process, and the challenge is provided for the erection of a high-altitude operation platform.
