Description
Technical field
The present invention relates to a kind of technical field of bridge construction, more particularly to a kind of Cast-in-situ Beam is without Temporary Piers stent.
Background technology
Rack construction refers to installation form, assembling reinforcement skeleton on stent, and the construction of cast on-site concrete, by
Relatively easy, the cost relative moderate in its construction, and be highly suitable for monolithic construction, therefore in bridge construction, especially
It is widely used in the construction of urban interchange and overpass.It is most common in the structure type of conventional stent at present to have
Full hall scaffold, i.e., using components such as stupefied beam, column, connectors, by controlling the spacing and step pitch of steel pipe scaffold tubes upright bar, if
The construction measures such as bridging are put, stent are arranged to geometrically stable system, the maximum feature of this stent is can assembling degree
It is high, suitable for the pier shaft height preferable situation of relatively low and geological condition.
For full hall scaffold, shortcoming is：Construction measure is more, and peace is torn open more lengthy and tedious；It needs to build several Temporary Piers, it is right
Foundation requirement is higher, and the bearing capacity and deformation of soil supporting layer and weak substratum are required to review checking computations, it is ensured that the two is relating to
And within the scope of allowing, and the ground range of stent scaffold tubes, the bearing capacity of ground and change are set up for entire bridge
Shape is intended to meet the requirements.
Temporary Piers are built in order to exempt, the prior art mostly makes stent " take root " on pier shaft using supplementary structure.In patent
Number for 201410090730.5 patent of invention in mention it is a kind of can be achieved it is cast-in-place without cushion cap approach viaduct concrete box beam limited bracket
Supporting structure, using new device --- hooping structure, in the case of realizing below access bridge pier shaft without cushion cap, in end bay position
The hooping structure by that can be used in turn repeatedly is put, solves the problems, such as stent " taking root ".Patent No. 201020264743.7
Utility model patent mentions the bracket in a kind of construction for high pier capping beam, and the wherein bracket of the lower edge end set of truss is inserted into
In the hole by specially treated reserved on pier shaft, remove the works such as basement process and pressure testing when constructing using raft support method from
Sequence effectively improves construction efficiency.
In said structure, stent must be fixed on by certain structure on pier shaft, either dismountable anchor ear knot
Structure or the truss structure being inserted into pier shaft, are required for constructing on pier shaft, have certain danger, also to pier shaft
Generate certain damage.
Invention content
The technical problem to be solved in the present invention is to provide it is a kind of to pier shaft without damage Cast-in-situ Beam without Temporary Piers stent.

Further, each arch section have preceding splicing end face and after splice end face, by forward and backward between adjacent arch section
Splice ends are connected in face of closing.
Further, there is odd number section to encircle section, respectively several symmetrical sides encircle units and erection and are connected to side arch list
Crown unit in member, splice ends face has a groove extended into arch section before unit is encircleed in the side, and rear splice ends face has
One convex body coordinated with the groove insertion in adjacent arch section, the forward and backward splicing end face of crown unit are in perpendicular
45°。
Further, splice ends face has a groove extended into arch section before the arch section, and rear splice ends face has one
With the convex body of the groove insertion cooperation in adjacent arch section.
Further, the cushion cap upper surface has a sagging recess for the installation of arch chassis.
Further, the arch chassis upper surface has a uniformly distributed bowl buckle stand base, the pedestal be by transverse slat and
The right-angle array plate that riser surrounds, combination plate opening are installed towards arch chassis.
Further, the link includes several connection segments being mounted between arch chassis, the connection segment
Between adjacent arcuate tray side, and the end of connection segment has the flange for being connected to arch tray side.
Further, it is connected between the arch chassis bottom by lacing wire.
The advantage of the invention is that：
（1）Original stent is substituted using arch chassis, low to foundation requirement without building Temporary Piers, arch chassis can
Dismounting is reused, and utilization rate is high；It is connected between arch chassis using link, stability is good；It is intensive due to arch chassis
Distribution pattern, is easily installed bowl buckle stent thereon, and Cast-in-situ Beam bottom mitigates overall weight, have to construction without using Bailey beam
Profit.
（2）When arch chassis span is larger, arch chassis is spliced to form using arch section, convenient for making, transporting and install.
（3）Encircle between section as the mating of groove and convex body, encircle and coordinate between section secured, be not easy to loosen, encircle between section
It compresses mutually under gravity, load-bearing capacity is good.
（4）Side arch unit is connected firmly, crown unit is faced only with splice ends using the mating of groove and convex body
The mode of installation is closed, is snapped tight against using the dead weight of crown unit and its upper pressure, realization, it is simple in structure, it is easily assembled.
（5）Since, not by direct cross force, arch chassis is only by limitings such as recesses in cushion cap upper end on arch chassis
Can, it is simple in structure, it is easy for construction.
（6）Chain-wales are made using combining plate on arch chassis, are installed for the rim of a bowl stent, the rim of a bowl stent installation jail
Gu support stability can ensure.
（7）Link is mounted on arch tray side, the installation of bowl buckle stent will not be caused to interfere, and the company of segmented
Frame is connect, is readily transported and installs.
（8）Arch chassis bottom end under weight can expand outwardly, and the setting of lacing wire prevents expansion so that arch-shaped bottom bottom
Frame structure is more stable.
