Description
Technical field
The invention belongs to build, the foundation pit support constructions technical field such as subway, more particularly to a kind of pattern foundation pit supporting structure stake top
Crown beam structure.
Background technique
The stake top crown beam of traditional foundation pit supporting pile, is generally used cast-in-place, but there are following problems using cast-in-place: the
First is that crown beam concrete using cast-in-place, needs supporting module, template construction is costly, holding time is long.Second is crown beam reinforcing bar
Cage binding, concreting need a large amount of workers, cannot achieve industrialization.
In spite of stake top crown beam using half prefabricated, half cast-in-place, although having saved the expense of part supporting module, construction
Speed is still not efficient enough, and process increases, and practice of construction cost is higher instead.Some stake tops use full precast reinforced concrete
Crown beam, with cast-in-place concrete ratio, although recycling and reusing can be realized, weight is larger, the connection precision of crown beam and support pile
It is required that also higher.
Summary of the invention
The object of the present invention is to provide a kind of foundation pit supporting pile apical cap beam constructing structure, with solve existing complete cast-in-place crown beam and
The defect of full precast reinforced concrete crown beam.
The technical scheme to solve the above technical problems is that a kind of foundation pit supporting pile apical cap beam constructing structure,
It include: steel truss crown beam, support pile, anchor cable, anchorage and backing plate；The steel truss crown beam is mounted on the top of the support pile,
It is mutually perpendicular to the support pile；The support pile is reinforced concrete structure；The anchor cable is embedded in support pile, anchor cable

It is linked together steel truss crown beam and support pile；The backing plate is mounted on the top of the support pile, is arranged in anchorage and supporting
Between stake.
Present invention foundation pit supporting pile apical cap beam constructing structure as described above, further, two adjacent steel truss crown beams
Using anchor bolts or adjacent two steel truss crown beams using welded connecting.
Present invention foundation pit supporting pile apical cap beam constructing structure as described above, further, the steel truss crown beam includes phase
Mutual first frame body and the second frame body disposed in parallel, the first frame body and the second frame body are linked together using tranverse connecting rod welding；It is described
Anchor cable is pierced by steel truss crown beam between the first frame body and the second frame body, and backing plate is arranged on the first frame body and the second frame body.
Present invention foundation pit supporting pile apical cap beam constructing structure as described above, further, first frame body includes top
Beam column, lower part beam column and vertical connecting rod, top beam column and lower part beam column are linked together using perpendicular.
The beneficial effects of the present invention are: the present invention uses steel truss structure, it is advantageously implemented industrialization, reduces construction site
Speed of application is greatly improved in number of workers.Meanwhile simple structure of the present invention, crown beam construction is not necessarily to supporting module, mixed without pouring
Solidifying soil, it is easy to operate.Steel truss crown beam can whole recycling and reusings, can both greatly save cost, can also be achieved energy conservation and environmental protection, it is real
It is high with value.

Specific embodiment
Hereinafter, the embodiment of foundation pit supporting pile apical cap beam constructing structure of the invention is described with reference to the accompanying drawings.
The embodiment recorded herein is specific specific embodiment of the invention, for illustrating design of the invention,
Be it is explanatory and illustrative, should not be construed as the limitation to embodiment of the present invention and the scope of the invention.Except what is recorded herein
Outside embodiment, those skilled in the art can also based on the claim of this application book and specification disclosure of that using aobvious and
The other technical solutions being clear to, these technical solutions include using any obvious to making for the embodiment recorded herein
The technical solution of substitutions and modifications.
The attached drawing of this specification is schematic diagram, aids in illustrating design of the invention, it is schematically indicated the shape of each section
And its correlation.It note that for the ease of clearly showing the structure of each component of the embodiment of the present invention, between each attached drawing
Do not drawn according to identical ratio.Identical reference marker is for indicating identical part.
Fig. 1 and foundation pit supporting pile apical cap beam constructing structure Fig. 2 shows an embodiment of the present invention comprising: steel truss
Crown beam 1, support pile 5, anchor cable 4, anchorage 3 and backing plate 2；The steel truss crown beam 1 is mounted on the top of the support pile 5, with institute
Support pile 5 is stated to be mutually perpendicular to；The support pile 5 is reinforced concrete structure；The anchor cable 4 is embedded in support pile 5, anchor cable 4
One end stretch out the top of the support pile 5；Anchor cable is placed in concrete in support pile filling concrete, effect master
It will be as the connector of steel truss crown beam and support pile.The anchorage 3 connects the end that anchor cable 4 stretches out support pile 5；Anchorage 3 will
4 tensioning fixation of anchor cable is linked together steel truss crown beam 1 and support pile 5；Anchorage is the locking device of anchor cable.The backing plate 2 is pacified
Mounted in the top of the support pile 5, it is arranged between anchorage 3 and support pile 5, billet is the device of transmitting and diffusion anchor force
Part.
The foundation pit supporting pile apical cap beam constructing structure of above-described embodiment is implemented by following steps:
Step 1, steel truss crown beam is completed according to design drawing in factory；Step 2, the more truss crown beam made is transported into construction
Scene；Steel truss crown beam is stacked into stockyard at the scene；Step 3, anchor cable is placed on concrete in support pile filling concrete
In；Step 4, supporting stake top concrete is picked into chisel in place；Step 5, positioning is measured according to construction drawing；Step 6, by steel truss
Frame crown beam section successively hangs billet and anchorage in place, by the anchor cable on support pile in crown beam；Step 7, pass through anchorage
Anchorage cable stretching is locked；Step 8, after Underground Construction to ground, fertile slot backfill, steel truss crown beam can be dismantled
Recycling, other projects exercise use again.
Compared with traditional cast-in-situ steel reinforced concrete crown beam and full precast reinforced concrete crown beam, the present invention uses steel truss knot
Structure is advantageously implemented industrialization, reduces construction site number of workers, speed of application is greatly improved.Meanwhile the present invention constructs letter
Single, crown beam construction is not necessarily to supporting module, is not necessarily to casting concrete, easy to operate.Steel truss crown beam can whole recycling and reusings, both
Cost can be greatlyd save, can also be achieved energy conservation and environmental protection, practical value is high.
The foundation pit supporting pile apical cap girder construction of the above embodiment of the present invention, moreover it is possible to be improved as follows, single steel truss hat
When beam is not able to satisfy the length that construction needs, need to carry out the connection of steel truss crown beam, two adjacent steel truss crown beams 1 use
Anchor bolts or adjacent two steel truss crown beams 1 are using welded connecting.It is more square using anchor bolt type connection later period disassembly
Just, but spare additional anchor bolt is needed.Welding manner is easy to operate early period, but later period dismantling recycling steel truss crown beam is compared
It is more difficult in anchor bolts.
The foundation pit supporting pile apical cap beam constructing structure of the above embodiment of the present invention, moreover it is possible to be improved as follows, such as Fig. 2 institute
