Description
Technical field
The utility model belongs to a kind of assembling multi-layer concrete underground garage.
Background technology
Along with the car industry fast development, car flies into common people house as swallow.But the parking lot is pitiably little, and parking difficulty has restricted the development of car industry, has also influenced the incity traffic and the appearance of the city.At present, parking lot is built all at the eyebrows and eyelashes in each big and medium-sized cities, but the old town can not build with having, and Xincheng District ground is expensive is reluctant to build, and the construction underground parking, its cost also is high.The underground garage of underground parking, particularly multilayer can't have been built again because conventional architectural design and job practices are used in the restriction of existing urban layout in the old town.Its main cause is to build the underground parking to need a cubic metre of earth heavy excavation.Fetch earth and put the slope, the occupation of land face area of construction operation is far longer than the floor space of building itself, and adopt open caisson method to construct, though need not put the slope, owing to be the on-site layering concreting, the on-the-spot operations such as reinforcing bar, a template, concreting, maintenance of compiling repeat repeatedly to carry out, inner frame construction has a strong impact on the open caisson construction operation, complex process, long in time limit, the cost height.And its price of the underground garage of steel work is expensive especially.
Summary of the invention
The utility model provides a kind of assembling square tube shape multi-layer concrete underground garage and preparation method thereof, takes up an area of big, complicated, the low high problem of valency of constructing of face to solve present garage.The technical scheme that the utility model is taked is: comprise concrete foundation, establishing the equipment room that the mutual corner connection of precast member for reinforcing bar concrete of unbonded prestressing tendon makes in four is connected with this concrete foundation upper fixed, the square tube wall tightens together by docking with this equipment room top, this square tube wall includes horizontal cross by piece, the vertical vertically mutual corner connection combine and assemble of prefabricated units side fascia of unbonded prestressing tendon tightens together, butt joint tightens together between each layer, in establish unbonded prestressing tendon the precast member for reinforcing bar concrete parking beam fix with the corresponding preformed hole cross-under of every layer of square tube wall, in establish unbonded prestressing tendon precast member for reinforcing bar concrete transhipment stop platform connect fixing with the square tube corner that is positioned at the place, ground, in establish unbonded prestressing tendon the right wall of precast member for reinforcing bar concrete transhipment layer and the left wall of transhipment layer dock with the square tube wall respectively fixing, in establish unbonded prestressing tendon precast member for reinforcing bar concrete transhipment layer lamina tecti and the right wall of transhipment layer with transport a layer left corner and connect fixing.
It is non-caked in concrete that the technical solution of the utility model makes full use of unbonded prestressing tendon, can slide.By very heavy stretch-draw, ground tackle locking makes the unbonded prestressing tendon of concrete component produce powerful tensile stress.Reaction force that this power produces acts on the interface and the prefabricated units itself of prefabricated units combine and assemble, makes it bear compressive stress.This power meets the stressed principle of concrete resistance to compression greater than tension.By ground tackle and very heavy accurate stretch-draw locking, it is accurate, error free to reach concrete prefabricated element combine and assemble size, the intensity height of its building structure combine and assemble.
Square tube shape underground garage design of building structures has the following advantages
1, its structure of multi-layer concrete underground garage all is made up of concrete prefabricated element, and prefabricated units can be produced in batches in factory, and the output height, quality is good, cost is low, efficient energy-saving.
2, the construction of assembling concrete prefabricated units is simple, convenient at the scene, speed is fast, need not large-scale hanging device.
3, adopt new method and proprietary material, facility, equipment combine and assemble concrete prefabricated element, building structure intensity is big, and the member group is to the precision height, and is safe and reliable.
4, open caisson construction can be built underground garage at narrow and small ground construction, uses the punching press square spade, promptly can accomplish cubic metre of earth zero backbreaking, and can guarantee the square tube shape exterior wall level that makes up, even, vertical subsidence again.
The square tube shape multi-layer concrete underground garage of the utility model design can be in narrow and small location, incity, city, old parking lot, and outside the buildings such as enterprise, hospital, office, hotel, market, in the institute, the roadside carries out construction.Under each surface area of 6 meters of length and width, can build every layer and stop 2, the underground parking garage that underground 11 layers of parking are 20.
