Abstract
The utility model relates to a sand section of thick bamboo temporary support is used in the installation of assembled precast box girder, including last and lower, characterized by: go up a section of thick bamboo with lower tin be the drum, the one end bottom is sealed with back cover plate, lower tin diameter is greater than the diameter of a section of thick bamboo, it has sand hole to open lower tin lateral wall lower part, the friable material seals for the sand hole, the packing has a fine sand in lower, upward tin fills up with the concrete, upward tin take back cover plate hold upwards insert down tin in, arrange in on the fine sand. Its point is: convenient to use, flexibility, the operation of being convenient for, the work efficiency high investment is few, and displacement, slope do not take place for repeatedly usable temporarily when supporting precast box girder.
Description
Technical field
This utility model relates to a kind of prefabricated pile equipment sand cylinder temporary support, belongs to technical field of bridge construction。
Background technology
In simple-supported thencontinuous prefabricated case beam installation, owing to prefabricated case beam need to be temporarily placed on temporary support, being not connected with temporarily between box beam, permanent bearing does not stress, and has built until middle cross beam, wet seam and could remove temporary support after reaching design strength and make permanent Bearing Seat Force。Therefore, temporary support must have enough strength and stiffness。Standard that existing temporary support is ununified and structure, be all on-the-spot interim arbitrarily make, be easily subjected to displacement, tilt in prefabricated case beam installation。
Summary of the invention
The purpose of this utility model is to provide a kind of energy temporary support prefabricated case beam, the sand cylinder temporary support be not subjected to displacement, tilted。
The purpose of this utility model is achieved in the following ways:
This utility model includes top cylinder and doffing, it is characterized in that: top cylinder and doffing are bottom cylinder, one end and close with back cover plate, the diameter of doffing is more than the diameter of top cylinder, lower sidewall at doffing has sand losing opening, sand losing opening friable material is closed, being filled with fine sand in doffing, top cylinder concrete fills up, and top cylinder band back cover plate end is inserted upwardly in doffing, is placed on fine sand。
The utility model has the advantages that: easy to use, flexible, it is simple to operation, work efficiency high investment is few, reusable, is not subjected to displacement when temporary support prefabricated case beam, tilts。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of doffing；
Fig. 3 is the structural representation of top cylinder。
Detailed description of the invention
With reference to accompanying drawing, this utility model includes top cylinder 2 and doffing 1, top cylinder and doffing are cylinder, the diameter of doffing is more than the diameter of top cylinder, doffing is made up of full weld back cover plate 5 bottom the steel pipe 3 of high 120mm, one end, top cylinder is made up of full weld back cover plate 9 bottom the steel pipe 7 of high 150mm, one end, and the back cover plate of top cylinder and doffing is the steel plate of 200mm × 200mm × 3mm。Lower sidewall at doffing has the sand losing opening 6 of 20mm × 10mm, is wound around steel pipe with glass adhesive plaster and is blocked by sand losing opening, is filled with fine sand 4 in doffing, and fine sand packed height calculates according to permanent height of support to be determined；Top cylinder concrete eight fills up, and top cylinder band back cover plate end is inserted upwardly in doffing, is placed on fine sand。
During application, two sand cylinder temporary supports of the present utility model of each placement immediately below the end of every prefabricated case beam, namely system of simple supporting is defined, wait having built middle cross beam, after the concrete strength of wet seam reaches designing requirement, break the glass adhesive plaster of sand losing opening with the reinforcing bar with point, fine sand slowly flows out from sand losing opening along with extruding and the Gravitative Loads of top cylinder, and top cylinder also drops to the bottom of doffing, temporary support is taken out, namely completes the system transform of simple-supported thencontinuous。
