Abstract
The utility model discloses a sand box is supported in uninstallation of large -span steel construction, including the inner skleeve, outer sleeve and sand discharge port, the endotheca barrel casing is in the outer sleeve, outer sleeve and inner skleeve section of thick bamboo wall contact each other, fill the sand grain in the outer sleeve, sand discharge port sets up in outer sleeve section of thick bamboo wall bottom both sides, sand discharge port is equipped with the valve that is used for controlling the sand grain exhaust velocity, the inner skleeve both ends are all sealed with sealing the board, the concrete has been pour in the enclosure space, bracing piece control is passed through to the inner skleeve falling head, the bracing piece adopts the square steel tube preparation to form, tailor the height of bracing piece at the uninstallation in -process along with the decline of inner skleeve, the welding of bracing piece both ends is being sealed between the board from top to bottom. The beneficial effects of the utility model are that: the utility model discloses simple structure, preparation are convenient, and the bearing capacity is big, safe and reliable, and the nature controlled is good, the precision is high, effectively solve the difficult problem of truss construction of large -span steel construction, but member reuse itself has still practiced thrift construction cost when guaranteeing construction safety.
Description
Technical field
The utility model relates to a kind of steel work unloading fastening, and particularly a kind of large-span steel unloading supports sandbox.
Background technology
Along with the continuous breakthrough of Architectural Design, long span building structure will increase, and when steel structure truss adopts high-altitude original position segmentation to install, needs temporary support to help location and the decline of truss, ensures the safety and stability of installation process simultaneously.In work progress, the normal jack sub-truss that uses declines, but due to jack lifting limited height and precision is inadequate, need the position repeatedly adjusting jack, complicated operation, workload is large, and jack lease expenses is high, adds a large amount of construction cost.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of large-span steel to unload and supports sandbox, temporary support is done when installing for steel structure truss, not only can secure support truss, ensure the safety and stability of installation process, and handling good, control accuracy is high, save construction cost simultaneously, increase economic efficiency.
The technical solution adopted in the utility model is: a kind of large-span steel unloading supports sandbox, and comprise inner sleeve, outer sleeve and sand removing hole, inner sleeve is enclosed within outer sleeve, and outer sleeve and inner sleeve barrel contact with each other.Perfusion sand grains in described outer sleeve, sand removing hole is arranged on both sides, outer sleeve barrel bottom.
Described sand removing hole is provided with the valve controlling the sand grains velocity of discharge.
Described inner sleeve two ends are all with hush panel sealing, and inner sleeve forms enclosure space, has built concrete in enclosure space.
Described inner sleeve bottom hush panel diameter is identical with the interior diameter of outer sleeve.
Described outer sleeve bottom adopts hush panel to close.
Described inner sleeve falling head is controlled by support bar.
Described support bar adopts square steel pipe to be made, and along with the height of the decline cutting support bar of inner sleeve in uninstall process, support bar two ends are welded between upper and lower hush panel.
The beneficial effects of the utility model are: a kind of large-span steel unloading that the utility model adopts supports sandbox, structure is simple, easy to make, bearing capacity is large, safe and reliable, and handling good, precision is high, the difficult problem of truss construction of effective solution large-span steel, component itself can reuse, while guarantee construction safety, also a saving construction cost.
