Abstract
This is a construction method of an assembled crane foot which substitutes traditional concrete structure by a combination of filling stuffs and a support platform of different section. The new structure is disassemble for reuse.
Description
Technical field
The present invention relates to the construction method and the structure of column foots such as all kinds of overweight tower cranes of building that need load-bearing or play supporting, electric power tower, communications tower, especially a kind of construction method and structure thereof of the removable and cantilevered hoist tower base class tower being convenient to reuse, specifically a kind of construction method of detachable tower foundation and structure thereof.
Background technology
As everyone knows, in order to carry constructional materials to high level, some lifting tower cranes all need be built in each building site.Because lifting appliance belongs to special equipment, its safety requirements height, therefore person in charge's parts such as building, safety, quality inspection all have strict requirement to its installation, use, operation, wherein most critical is the installation on basis, because it is directly connected to the safe operation of crane gear, the column foot that requires crane gear is installed has very strong withstand voltage and resistance to capsizing, and designs part from security consideration, and its safety factor is generally all bigger.Thereby existing column foot all adopts steel bar concrete to add the structure of anchor pole, this manufacture method and structure one are that disposable input is bigger, tower crane for 40-80T/M, ten thousand yuan of the general equal 3-7 of its column foot input, and can not reuse, after engineering finishes, the column foot of building that spends huge sums will go out of use, and its cleaning difficulty is also quite big, generally all it is arranged on the position that does not influence normal performance of other function of building and expansion when therefore designing; The 2nd, the construction period is long, when adopting the concrete structure, because 28 days intensity level need detect in safety supervision department, body of the tower could be installed after qualified, and the manufacturing again of defective then need so not only has a strong impact on the construction period, and influences the reasonable use in place.
Summary of the invention
The objective of the invention is at the construction period of existing all kinds of hoist towers, load-bearing tower, supporting tower, the existence of support tower column foot long, and not reproducible utilization, waste serious problem, analyzing the main stressed of column foot, the construction method and the structure thereof of inventing a kind of detachable tower foundation on the basis of positive pressure.
Technical scheme of the present invention is:
A kind of construction method of detachable tower foundation is characterized in that it may further comprise the steps:
At first, on the ground of need installation column foot, dig a foundation ditch by designing requirement;
Secondly, or be installed in the foundation ditch the variable cross-section cushion cap is all or part of earlier, in the foundation ditch around the variable cross-section cushion cap, add inserts again; Or in foundation ditch, add earlier inserts, and then the variable cross-section cushion cap is installed on its surface;
At last, the bottom with tower links to each other with the cushion cap piece of the variable cross-section cushion cap the superiors.
The tower-base structure that matches with said method of the present invention is:
A kind of detachable building column foot comprises foundation ditch, inserts, variable cross-section cushion cap, and inserts is filled in the foundation ditch, it is characterized in that described variable cross-section cushion cap or all is arranged on the bearing stratum that meets load bearing requirements of foundation ditch, is filled with inserts around it; Or all being positioned at the foundation ditch surface, its undermost cushion cap piece is installed in the upper surface of the inserts that meets load bearing requirements; Or part is arranged in foundation ditch, and part is positioned at outside the foundation ditch, and the lower support of described variable cross-section cushion cap is meeting on the inserts bearing stratum of load bearing requirements, be arranged in foundation ditch the variable cross-section cushion cap around be filled with inserts; The cushion cap piece of the described variable cross-section cushion cap the superiors links to each other with the bottom of tower.
Described inserts is sandstone material, prefabricated section or the body structure that sand, building stones are housed.
Described prefabricated section is for having interlocking structure metal derby, cement block or cement steel prefabricated section.
Described prefabricated section links to each other by connecting rod, and the described body structure that sand, building stones are housed also links to each other by connecting rod.
Described variable cross-section cushion cap is connected with the anchor pole that inserts in the inserts.
The cushion cap piece of described variable cross-section cushion cap is rectangle, square, triangle, equilateral triangle, circle, polygon or its combination that size changes in gradient.
Described variable cross-section cushion cap or be monolithic construction, or split-type structural for linking to each other and form by some cushion cap pieces.
Described variable cross-section cushion cap or be solid, or be the hollow body of frame construction.
Be provided with reinforcing rib in the described frame construction.
The framework that is used to load inserts is installed in the described foundation ditch.
The present invention has the following advantages:
1, easy accessibility cuts the waste.
2, can shorten construction period.
3, the fabricating yard is unaffected, after especially use finishes, can easily foundation ditch be removed and recover former state.
4, safe and reliable, because the bottom active force of tower crane passes through the repeatedly transmission of variable cross-section cushion cap, its effect final and ground is repeatedly decomposed, no matter be that the normal pressure or the power of toppling are all very little, can not cause sinking of ground or inclination.Especially when the variable cross-section cushion cap is installed in the foundation ditch, rely on the active force of inserts and the pulling force of anchor pole can satisfy instructions for use fully, the overturning or slip resistance analysis bearing diagonal that adds when adding the tower crane installation and the effect of the girt that links to each other with wall, unstable active force on the tower crane is less, and therefore removable structure of the present invention can satisfy safety requirements fully.
5, relatively simple for structure, sandstone material cost is lower, and can reuse, and prefabricated section have once drop into reusable, and install, dismantle very convenient, buckle structure design by prefabricated section itself or install mode such as connecting rod that each prefabricated section is connected into is as a whole, its carrying and resistance to capsizing are stronger.
6, purposes is wide, not only can be used for common building lifting column foot, and can be used for the often column foot of mounting or dismounting of needs such as electric power, communication, advertisement, is particularly suitable for the building site, crosses the column foot that work-yards are often changed in street advertisement etc.
