Description
Technical field
The invention belongs to technical field of civil engineering, fine more particularly, to being realized using mold in concrete structure seam crossing
Tie up continuous construction method.
Background technique
Concrete with fiber（Such as common fiber concrete, ultra-high performance concrete）Due to its excellent every power
Performance is learned, civil construction field is widely used in.Fiber in concrete substrate can block the development of distress in concrete, thus
Improve its tension, bending resistance, shearing strength, shock resistance, it is antifatigue, split rear toughness and durability also and have larger improvement.However
Presently, there are technical problem be that either precast construction or gradation pouring structure is all difficult to avoid that seam（Including construction
Seam, boundary seam etc.）Presence, this also related to new-old concrete interface connection the problem of, especially for band fiber
Concrete structure, it is discontinuous that the presence of seam will lead to fiber, thus make seam become its weak part.
Common joint form has carvel joint, sawtooth seam, step-lap laminated, T and G joint etc. in engineering.Carvel joint due to
Its construction is simple, application is wider, but its seam crack-resisting intensity is insufficient, is easily damaged；Sawtooth seam and step-lap laminated are in carvel joint
On the basis of increase the contact area at seam interface, to increase the breaking resistance of seam crossing, but reinforcing effect it is not obvious enough and
Construction formwork is complicated；T and G joint makes seam further through the interlock action that tongue and groove constructs on the basis of increasing seam contact area
The tensile stress of receiving is partially converted into shear stress, further improves the breaking resistance of seam, but equally increases the difficulty of construction
Degree, and the quality of seam is also difficult to ensure.
Though these above-mentioned seam construction measures can partially improve joint strength, fail fundamentally to solve due to seam crossing
The seam crack-resisting strength reduction problem that fiber is caused by artificial " truncation ", and the advantage of structure and material itself is not played.
Summary of the invention
The case where for the prior art, implements reliable, convenient, fast for construction, effect the purpose of the present invention is to provide a kind of
Rate is high and can guarantee construction quality and concrete is made to realize that seam crossing keeps continuous in gradation casting process, in addition, can also
It enough improves the anti-crack ability of seam crossing and what structure is reasonable realizes that fiber is continuous in concrete structure seam crossing using mold
Construction method.
In order to realize that above-mentioned technical purpose, the technical solution adopted by the present invention be：
It is a kind of to realize the continuous construction method of fiber in concrete structure seam crossing using mold, in a plate-like mold side

Connecting plate, then the exposed fiber partial insertion connecting plate of mold combs fiber, makes when being inserted into connecting plate
It is uniformly inserted into connecting plate, then separates mold with connecting plate, and being formed has the connecting plate for being inserted with fiber；
（4）Step will be passed through（3）Treated connecting plate and concrete-pouring template with merge connecting plate is fixedly mounted on it is pre-
If concrete seam, one end that fiber is exposed on connecting plate is made to be located at the default concrete side poured for the first time；
（5）It pours and conserves for the first time：The concrete side that default first time pours is poured and maintenance is handled, is made outside fiber
One end of dew is embedded in concrete；
（6）Demoulding：Connecting plate is slowly removed, then dismantling concrete formwork for placing again along fibre length direction, makes fiber
The other end is exposed at the default concrete side poured for the second time；
（7）Seam surface treatment：Surface laitance and unconsolidated formation are removed to the joint face of the concrete side poured for the first time, so
Blow down the dust near joint face again afterwards；
（8）It pours and conserves for the second time：The default concrete side poured for the second time is poured and maintenance is handled, makes fiber
The other end is embedded in concrete, is realized fiber is continuously coupled in the concrete that adjacent different batches pour.
It preferably, further include step（9）, the step（9）To repeat step（1）Extremely（8）, realize that multiple concrete pour
The seam crossing fiber for building face is continuously constructed.
Preferably, step（1）Described in mold can be rectangular plate-like structure.
Preferably, step（1）Described in mold be timber, steel or plastic material molding, the pore aperture being drilled with
It is 1.2~1.5 times of fibre diameter, the depth of pore is 0.4~0.6 times of fibre length, and the pore is blind hole.

It is furthermore preferred that the fiber can be steel fibre.
Preferably, step（3）In by way of manually or mechanically pressing will expose outside mold fiber partial insertion connect
Fishplate bar.
More preferably, step（3）After middle fiber insertion connecting plate, the method on fibre length direction surface corresponding with connecting plate
Line direction is parallel to each other or is formed the angle less than 20 °.
Preferably, step（3）Fiber in middle insertion connecting plate is not pierced by from the other side of connecting plate, the connecting plate
Material is foamed plastics, cork sheet, high-density sponge, pitch, rubber, plasticine or clay.
Preferably, step（5）And step（8）The seam crossing of middle concreting using normal concrete, fiber concrete,
High performance concrete or ultra-high performance concrete pour.
A kind of application for above-mentioned construction method comprising above-mentioned construction method is used for continuous cast-in-place engineering and prefabricated
Assembled engineering.
Using above-mentioned technical solution, the device have the advantages that being：The present invention program passes through in concrete joint
Place is connect in succession using Fiber Bridge, without the joint form by changing seam shape, encrypting the complexity such as arrangement of reinforcement or deformed steel flats
Improve seam crossing mechanical property, fundamentally solves the problems, such as that concrete structure is discontinuous in seam crossing fiber.Also pass through
Pore mold is made, the work of fiber insertion connecting plate can be made easy to accomplish, and construct quickly, position of fibers insertion is accurate.Carefully
Pitch of holes, so that mold is reusable, greatlys save construction cost by the fiber spacing production of design.In addition, the mould of production
Tool is suitable for various concrete structure seams, due in long-term work progress, ability it is contemplated that insertion variety classes fiber
The associated construction in domain designs or Field Force has formd certain inertial thinking, i.e. site operation mostly uses greatly assembled in situ
Cast in situs or other do used mode now to construct, and use prefabricated component form it is also more rare, especially
It lays in the fiber of the concrete seam of different batches very rare on prefabrication solutions, when site operation, is carried out in seam crossing
The mode of fiber not only inefficiency is adlibed, but also the difficulty for laying uniformity is big and often can not be done over again or be done over again
It is with high costs, it is time-consuming and laborious, and the solution of the present invention connecting plate and formwork for placing cooperation before can pass through mold transfer
The form of fiber is by the uniformly distributed one side in connecting plate of fiber, which is not necessarily to execute-in-place and can be prefabricated, so that live
When pouring, only needs after quickly being cooperated connecting plate and formwork for placing, the work for pouring link can be carried out, substantially increased
Site operation efficiency and the risk of doing over again for reducing the link.In addition, the method for the present invention quick construction, can reduce project cost, have
Preferable promotion prospect.
