Description

A kind of base configuration of open caisson stereo garage
Technical field
The present invention relates to stereo garage technical field of construction more particularly to a kind of base configurations of open caisson stereo garage.
Background technique
With the continuous improvement of people's living standards, more and more people have purchased private car;Traffic and ring to city Border plays great influence.And the appearance of parking difficulty problem, also huge business opportunity and wide is brought to Mechanical parking system industry Wealthy market.In this business opportunity and compete and when deposit, the Mechanical parking system industry in China also will from Rapid development stage into Enter the stable development stage.Future market is huge, but the demand to product, it will to two extreme developments: one extremely It is the extreme of price, market largely needs the Mechanical parking system of low price, as long as it can achieve the purpose that increase parking stall, It can guarantee most basic service performance, be dominated the market with price advantage, the market share of this part is estimated to be up to 70%- 80%;Another is extremely exactly the extreme of technology and performance, it is desirable that parking apparatus has superior service performance, easily operates Mode, efficiently access speed.By the summary of domestic and international Mechanical parking system use experience, it can be found that people are in the machine of utilizing When tool parking equipment access vehicle, what is pursued first is access vehicle speed, waiting time and comfort level.In addition, following machine Tool parking apparatus market will more focus on perfect after-sales service system, and remote monitoring system, remote failure lead processing system will It is the target that user pursues.With the development of China's economy continuously and healthily, perfect, the Mechanical parking system industry general of urban planning As an energetic southern exposure industry, the technology of Mechanical parking system will also obtain significant progress.
In today of rapid economic development, surface structures and greening all gradually increase, so that ground parking stall is seriously not Foot, therefore, underground three-dimensional garage become a development trend, and how to construct underground three-dimensional garage is also those skilled in the art The project unanimously studied.
For example, a kind of precast spliced sinking type parking disclosed in the patent of invention application No. is 2017100964937 In the engineering method in library, caisson structure includes several index beds of bottom blade foot layer and top, and the installation accuracy of blade foot layer determines The assembling quality of upper layer open caisson index bed, the construction method of blade foot layer are as follows: be disposed vertically blade foot block, and by several blade foots Block is successively spliced to form pit shaft first layer (blade foot block inner wall lower is connected to form wedge shape section with outer wall diagonally downward), and makes it The method being disposed vertically is to support blade foot block jointly by support frame, positioning limit device, diagonal brace, after a blade foot block is installed Remove support frame, positioning limit device, diagonal brace, the construction method use prefabricated assembled blade foot structure, because component be it is abnormally-structured, Volume is larger, and transport, lifting turnover need two to three times, higher cost, and assembled needs a large amount of Auxiliary support brackets, splicing seams precision It is not easy to guarantee, blade foot solid-section later period waterproof is not easy to handle.
In another example disclosed in the patent of invention application No. is 201711007754.X a kind of sliding formwork component and application its In caisson cutting edge layer slding form operation method, disclose a kind of sliding formwork component, including slideway, exterior sheathing, inner template, two side templates and Several sliding slots installed for exterior sheathing and inner template, the exterior sheathing bottom are arranged on the slideway for several connection fixtures Portion is provided with several outer stabilizer blades, and installation movement along the chute, the inner template bottom is arranged on the outside of slideway in the outer stabilizer blade Several interior stabilizer blades are provided with, installation movement along the chute is arranged on the inside of slideway in the interior stabilizer blade, and the side template setting exists The two sides of inside and outside template are simultaneously connect by connection fixture with inner template and exterior sheathing.Although ensuring that blade foot construction is completed Line style vertical precision afterwards, to guarantee the assembling quality of upper layer open caisson standard segment, however cast in situs leads to long construction period, sternly The construction period of stereo garage is affected again, and the measure bottom and side wall waterproof is all relatively difficult.
And these prefabricated or pouring piece structural strengths are not high, and breakage is easy in construction, cause its service life limited, Affect the normal use of stereo garage.
Therefore, for developing the base configuration of new open caisson stereo garage a kind of, not only there is urgent researching value, With good economic efficiency and commercial application potentiality, where this power exactly of the invention being accomplished and basis.
Summary of the invention
