Description
Technical field
The utility model belongs to a kind of assembling multi-layer concrete underground garage and preparation method thereof.
Background technology
Careless 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,, compile operations such as reinforcing bar, a template, maintenance and repeat repeatedly to carry out owing to be the on-site layering concreting, 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 cylindrical multi-layer concrete underground garage and preparation method thereof, to solve the problem that present garage floor space is big, long in time limit, cost is high.The technical scheme that the utility model is taked is: comprise concrete foundation, the collar tie beam of forming by articulating by the semicircle collar tie beam, stack between cross-under composition subsurface equipment and fixedly connected with concrete foundation, the annular exterior wall of each layer adopts outer articulating combine and assemble to form, the bottom is fixedlyed connected with concrete foundation, adopt butt joint to be connected and fixed between about the annular exterior wall of each layer, bottom parking beam is fixedlyed connected with concrete foundation, bottom collar tie beam and equipment room cross-under are connected and fixed, each layer collar tie beam and the mutual clamping connection of hoistway column are connected and fixed, bracket and annular exterior wall cross-under are connected and fixed, parking beam one end and hoistway column interconnect fixing, the other end and bracket corner connection are connected and fixed, annular cover plate and the corner connection of annular exterior wall top layer are connected and fixed, fixedly connected with the superiors collar tie beams in hoistway column top, transfer room lamina tecti and the superiors' collar tie beam cross-under are connected and fixed.
The whole underground garage of the utility model is established the building structure of the concrete prefabricated element combine and assemble of unbonded prestressing tendon in all adopting except that bottom of the reservior and Equipment Foundations.This building structure makes full use of the concrete resistance to compression much larger than tension, unbonded prestressing tendon intensity height, and it is not bonding to slide in concrete.And characteristic such as stretch-draw of ground tackle, locking, butt joint.Adopt butt joint, cross-under, corner connection, articulating combine and assemble method, monomer concrete prefabricated element beam, plate, post, wall connection are tightened together, make each bonding surface of combination prefabricated units be in pressured state, its level of monolithic architecture structure and vertical direction all have high-intensity compressive pre-stress.
This utility model has been abandoned concrete prefabricated element and has been relied on the technology of welding combine and assemble.The open caisson construction that the coordinative construction working area is little, high-quality is built up the cylindrical multi-layer concrete underground garage fast.The advantage of this building method is that building structure intensity is big, member merging precision height, combine and assemble speed is fast, the cost low quality is good.
The utlity model has following advantage
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, combine and assemble concrete prefabricated element at the scene, construction is simple, convenient, 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 floor space is narrow and small, uses punching press ring shovel, promptly can accomplish cubic metre of earth zero backbreaking, and can guarantee the annular exterior wall level that makes up, even, vertical sedimentation again.
The cylindrical 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.Just can build the underground parking garage that stops more than 80 at each surface area of 20 meters of length and width.Construction period is short, and speed is fast.Totally-enclosed environmental protection construction, very little to the surrounding enviroment influence.This technology has very strong competitiveness and vast market in the construction of underground garage, and possesses the ability of exploring world market.
