Abstract
The invention relates to a construction method for mounting a lifter on a top plate of an underground parking garage, belonging to the building technology. The method comprises the following steps: 1) designing a hanging basic support system of the lifter; 2) locating and staking out a vertical rod; 3) mounting the vertical rod and a level rod; 4) mounting main edges; 5) mounting auxiliary edges; 6) mounting a double bridging; mounting the vertical and continuous double bridging at the periphery and longitudinal and transverse middle parts of the support system; 7) mounting a beam slab mould of the top plate of the underground parking garage; 8) binding steel bars; 9) mounting ground bolts of the lifter; 10) pouring concrete to the top plate of the underground parking garage; and 11) mounting the lifter. The method is safe and reliable in stress performance, convenient in construction, and capable of solving the technical problem that the top plate of the underground parking garage cannot bear the lifter; compared with the traditional construction method for mounting the lifter on a foundation slab of the underground parking garage, the construction method in the invention can levelly transport in one step, can reduce the comprehensive cost for constructing and transporting, and can ensure that the constructing and transporting are not blocked.
Description
Technical field
The present invention relates to the hoist job practices is installed on a kind of underground garage top board, belong to technical field of buildings.
Technical background
In recent years, the underground garage form that connects the place is set in high stored building group, throughout the country extensive use in the design.Highrise building is in the main body construction stage, for the convenient construction personnel go up downstairs the vertical transport with material, necessary installation hoist; But because the underground garage area is huge; Its outward flange is far apart from main building, so the main building construction elevator can only install near the basic raft plate it, and on the underground garage top board, reserves hole is installed; Construction material can carry out vertical transport after adopting manual work to be transported to underground garage hoist position; Cause last speed downstairs of constructor and transport of materials efficient seriously to reduce, greatly influenced construction speed and economic benefit, become a national generality technical barrier that urgency is to be solved.
Summary of the invention
The object of the present invention is to provide the hoist job practices is installed on a kind of underground garage top board, safe and reliable, can significantly improve the construction conevying efficiency.
The hoist job practices is installed on the underground garage top board of the present invention, takes following steps:
1, the hoist job practices is installed on a kind of underground garage top board, it is characterized in that taking following steps:
1) the unsettled base support System Design of construction elevator: multiply by 1.5 the coefficient of impact according to the whole load of construction elevator, the unsettled base support system of design hoist;
2) location unwrapping wire: on the raft plate of underground garage basis, emit hoist base support system vertical rod position coordinates net;
3) set up vertical rod and horizon bar: after the form bracing system vertical rod was accurately in place, the adjustable rest of the formula of putting more energy into of diameter>=Φ 30 was inserted in its top, forms the axle center power transmission, sets up the support system horizon bar by step pitch≤1.8m then;
4) the stupefied installation of supporter owner: the i iron master who in the U-shaped supporting plate of adjustable rest, places designing requirement is stupefied;
5) support system time stupefied installation: it is inferior stupefied above the i iron master is stupefied, to place the lumps of wood by spacing;
6) set up bridging: set up vertical bridging continuously with middle part in length and breadth is two-way in that support system is peripheral, the angle of bridging and 45 °～60 ° of ground formation;
7) underground garage top board beam-slab template is installed: template adopts the thick bamboo plywood of >=15 ㎜, and form joint place adopts both sides' wood arranged side by side fixing;
8) assembling reinforcement: underground garage top board beam reinforced steel bar colligation;
9) the hoist stone bolt is installed: snap the line is confirmed hoist stone bolt position on template, foot bolt regularly on beam reinforced steel bar;
10) concreting: the beam slab concrete monobloc cast of underground garage top board and hoist basis drop shadow spread;
11) hoist is installed: treat to install when underground garage concrete roof intensity reaches C20 at least hoist.
The support system steel pipe all adopts the Q235 shape steel tube of Φ 48mm * 3.0mm among the present invention.
Compared with prior art, the present invention has following beneficial effect:
(1) the present invention installs hoist on the underground garage top board, can utilize open underground garage top board as horizontal shipping platform, makes the construction level transportation unblocked, settles at one go, significantly improves the construction conevying efficiency.
(2) the present invention utilizes the underground garage top board as the hoist basis, saves concrete 5 * 5 * 0.5=12.5m
3, and save hoist basis arrangement of reinforcement.
(3) the underground garage top board beam slab template supporting system of hoist basis drop shadow spread and other scopes is constructed synchronously, and only vertical pole ' s span, main stupefied different does not increase the support system expense basically, and cost is low.
(4) the support system simple structure of hoist basis drop shadow spread is safe and reliable, workable, is convenient to guarantee construction quality.
