Abstract
The utility model discloses a thin-walled cold-formed steel miniature pile, including grout, rubble aggregate, C shaped steel, batten plate, diaphragm, C shaped steel forms lattice column through a plurality of batten plate welding, and lattice column both ends set up the diaphragm, and grout, rubble aggregate and lattice column form the pile body through pouring; the roll-cold-formed thin-wall steel micro-pile of the utility model has simple structure and convenient manufacture; and the cold-formed thin-wall steel skeleton replaces a steel reinforcement cage, so that the lower steel skeleton of the miniature pile is easy to operate in construction, and the construction efficiency and the engineering quality are obviously improved.
Description
Technical field
This utility model belongs to building field, particularly a kind of light gauge cold-formed steel shape mini pile.
Background technology
Mini pile refers generally to a footpath and is more than the little of 30, employing boring and slip casing by pressure construction technology less than 400mm, slenderness ratio
Diameter stake.Mini pile, because of advantages such as its load-carrying properties are high, construction equipment is simple, construction space is little, noise is little, the most extensively should
In Transmission Tower-line line pole tower basis, particularly apply in the construction of soft soil foundation line project.
But, pouring mini pile needs to make in advance steel reinforcement cage, for the simple mini pile of construction technology pours,
Making steel reinforcement cage and seem relatively complicated, its fabrication and installation not only consume a large amount of reinforcing bar, and need to put into more man-hour, add
The difficulty of construction and cycle.
Utility model content
The purpose of this utility model is that offer develops that one significantly improves efficiency of construction, stress performance is good and is suitable for
Light gauge cold-formed steel shape mini pile in existing pole and tower foundation engineering.
The technical solution realizing this utility model purpose is:
A kind of light gauge cold-formed steel shape mini pile, including cement mortar, crushed stone aggregate, C-type steel, batten plate, tabula, described C-type steel
Forming lattice column by the welding of some batten plates, lattice column two ends arrange tabula, and cement mortar, crushed stone aggregate and lattice column are by pouring
Form pile body.
This utility model compared with prior art, its remarkable advantage:
(1) lattice column of this utility model light gauge cold-formed steel shape mini pile, replaces tradition steel reinforcement cage to hang in boring, it is not necessary to again
Carrying out the making of steel reinforcement cage, this method is simple to operate, in hgher efficiency, can be prevented effectively from that existing method consumable quantity is big, make
The problem such as loaded down with trivial details；And light gauge cold-formed steel shape skeleton substitutes steel reinforcement cage so that in construction, under mini pile, type steel skeleton easily operates,
Significantly improve efficiency of construction and construction quality.
(2) pile concrete is played higher constraint work by the lattice column of this utility model light gauge cold-formed steel shape mini pile
With, compared with prior art, its horizontal bearing capacity has obtained certain raising.
(3) this utility model light gauge cold-formed steel shape miniature pile construction is simple, and stress performance is good, it is adaptable to power transmission rod column foot
In plinth engineering construction.
Below in conjunction with the accompanying drawings this utility model is described in further detail.

Detailed description of the invention
In conjunction with Fig. 1 and Fig. 2:
This utility model one light gauge cold-formed steel shape mini pile, including cement mortar 1, crushed stone aggregate 2, C-type steel 3, batten plate 4,
Tabula 5, described C-type steel 3 forms lattice column by the welding of some batten plates 4, and batten plate uses solder design, batten plate with the C-type steel edge of a wing
Size and spacing should meet the relevant regulations of " Code for design of steel structures " (CB50017-2003).Lattice column two ends arrange tabula
5, lattice column replaces steel reinforcement cage to hang in boring, and cement mortar 1, crushed stone aggregate 2 and lattice column are by pouring formation pile body.
Described C-type steel 3 uses cold-formed thin-walled C steel, cold-formed thin-walled C steel specification limit to be C~ C, and effectively flakiness ratio should meet the phase of " Technical code for design of coldformed thin wall steel structures " (GB50018-2002)
Close regulation.
Described tabula 5 uses two single angle square crossings to arrange, by solder design between single angle, its two ends are respectively
Weld with the web of C-type steel 3.
Described batten plate 4 uses equal leg angle.
The formation of pile of light gauge cold-formed steel shape mini pile include boring, clear hole, hang, slip casting etc. of rockfilling, should meet " building
Standard for pile foundation " relevant regulations of (JGJ 94-2008).
