Abstract
The invention discloses a kind of combination steel construction supporting construction, including combination shaped steel plate pile, bracing members, base surface, angle steel lattice column and stand column pile, the bracing members include 3, and High Strength Non-shrinking Filling Material is filled between first of bracing members and second bracing members and second bracing members and third road bracing members.The present invention combines steel construction supporting construction using bracing members from heavy and light, is convenient to mount and dismount and rapidly, and can reduce enclosure wall causes deformation to increase because no supporting time is long and soil body creep；Precompression can be applied, and precompressed force value is adjusted according to enclosure wall deformation in time and is controlled, as tool-type structure, can be repeatedly used, steel pipe inner supporting construction quality is relatively easy to control, and is not limited by stratum, suitable for the base pit engineering under various geological conditions.Have the characteristics that easy to operate, degree of safety is high, is suitble to promote and apply.
Description
Technical field
The invention belongs to technical field of building construction, are related to a kind of combination steel construction supporting construction.
Background technique
The a large amount of deep-foundation pit engineering in China start from the 1980s, due to urban skyscraper rapid development, underground
The various needs such as parking lot, skyscraper buried depth, people's air defense, skyscraper need to build certain basement.In recent years, due to city
The rapid development subway station of city's subway engineering, local section open cut etc. are also related to a large amount of base pit engineering, intersect in two-wire
Subway station, foundation pit is as deep as 20-30m.There is also underground power houses, the Excavation problems of underground pump house for water conservancy, electric power.
The either deep-foundation pit engineering of skyscraper or subway, due to being excavated in city, around foundation pit usually
There are the various structures such as traffic main artery, built construction or pipeline, this relates to a critically important content of excavation of foundation pit,
Protect the safe handling of its periphery structures.And general pattern foundation pit supporting structure be mostly temporary structure, investment also easily cause greatly very much
Waste, but supporting construction is dangerous and certainly will will cause engineering accident.
Summary of the invention
It is an object of the invention to overcome defect existing for above-mentioned technology, a kind of group easy to operate, degree of safety is high is provided
Close steel construction supporting construction.
Its specific technical solution is：
A kind of combination steel construction supporting construction, including combination shaped steel plate pile, bracing members, base surface, angle steel lattice column and stand column pile,
The bracing members include 3, first of bracing members and second bracing members and second bracing members and third road bracing members it
Between be filled with High Strength Non-shrinking Filling Material.
Further, the bracing members use material for steel pipe or fashioned iron.
Further, the steel pipe is f609 steel pipe, wall thickness 10,12,14mm;Type steel support is H profile steel, or combined
Steel.
Further, the bracing members horizontal layout, which uses, supports support, angle brace, fringe truss, frame or dome-shaped.
In the specific application process, flat shape preferably uses angle brace as size is smaller, size is larger close to rectangular foundation pit
Preferably use annular, fringe truss support;Rectangular foundation pit is then preferably used to support or to support plus angle brace etc..Axis of support should avoid main body
The column net axis of engineering, horizontal and vertical supporting arrangement will consider convenient for cutting the earth, structure superstructure is arranged and convenient for tearing support and support replacement open
Deng.When the horizontal distance between adjacent supports is larger, eight words preferably are set in supporting base end portion and are supportted to reduce supporting point spacing;Column one
As should be arranged in the point of intersection vertically and horizontally supported or plane purlin (frame) posture support node at, and should avoid major project beam,
Column and load-bearing wall displacement, column spacing depends on the stability of supporting rod and the size of vertical load, generally no more than 15m
。
Beneficial effect：
The present invention combines steel construction supporting construction using bracing members from heavy and light, is convenient to mount and dismount and rapidly, can reduce enclosure wall because of nothing
Supporting time is long and soil body creep and deformation is caused to increase；Precompression can be applied, and adjusted in time according to enclosure wall deformation
Precompressed force value is controlled, and as tool-type structure, can be repeatedly used, steel pipe inner supporting construction quality is relatively easy to control, no
It is limited by stratum, suitable for the base pit engineering under various geological conditions.Have the characteristics that easy to operate, degree of safety is high, is suitble to push away
Wide application.
Detailed description of the invention
Fig. 1 is the schematic diagram of present invention combination steel construction supporting construction.
Specific embodiment
Technical solution of the present invention is described in more detail in the following with reference to the drawings and specific embodiments.
Referring to Fig.1, a kind of combination steel construction supporting construction, including combination shaped steel plate pile 1, bracing members 2, base surface 3, angle steel
Lattice column 4 and stand column pile 5, the bracing members include 3, first of bracing members and second bracing members and second bracing members
High Strength Non-shrinking Filling Material is filled between third road bracing members.
The bracing members use material for steel pipe or fashioned iron.
The steel pipe is f609 steel pipe, wall thickness 10,12,14mm;Type steel support is H profile steel, or combination fashioned iron.
The bracing members horizontal layout, which uses, supports support, angle brace, fringe truss, frame or dome-shaped.
In the specific application process, flat shape is close to rectangular foundation pit, such as combination steel construction supporting construction of the invention
Size is smaller preferably to use angle brace, and size is larger preferably to use annular, fringe truss support;Rectangular foundation pit is then preferably used to support or to support
Add angle brace etc..Axis of support should avoid the column net axis of major project, and horizontal and vertical supporting arrangement will consider to cut the earth, tie
Structure superstructure is arranged and convenient for tearing support and support replacement etc. open.When the horizontal distance between adjacent supports is larger, preferably it is arranged eight in supporting base end portion
Word is supportted to reduce supporting point spacing;Column should generally be arranged in the point of intersection vertically and horizontally supported or plane purlin (frame) posture support
At node, and major project beam, column and load-bearing wall displacement should be avoided, column spacing depends on the stability of supporting rod and vertical
The size of load, generally no more than 15m.
The foregoing is only a preferred embodiment of the present invention, the scope of protection of the present invention is not limited to this, it is any ripe
Know those skilled in the art within the technical scope of the present disclosure, the letter for the technical solution that can be become apparent to
Altered or equivalence replacement are fallen within the protection scope of the present invention.
