Description
Technical field
Patent of the present invention belongs to building materials construction applications, the ultra-high performance concrete circle that a kind of self-locking connects
Post permanent template and construction method thereof.
Background technology
Comparing traditional building form, it is fast that permanent template has speed of application, easy construction, it is not necessary to formwork and dismounting,
Reduce the advantages such as human cost.When the scantling of institute's molding is less, can be solved by monoblock permanent template.But work as structure
When part size is bigger, due to transport, the restriction of lifting cannot directly use monoblock permanent template to solve, it is necessary to by pin-connected panel
Permanent template, and traditional pin-connected panel component generally requires a large amount of cross-brace, support system, sets up complex, expends big
Amount manpower and materials.
Summary of the invention
The problem that it is an object of the invention to overcome prior art to exist, it is provided that the very-high performance that a kind of self-locking connects mixes
Solidifying soil steel pipe column-form and construction method thereof.This cylinder permanent template is prefabricated in the factory, and mould material uses steel pipe and surpasses
High performance concrete.
The present invention adopts the following technical scheme that and realizes:
The ultra-high performance concrete cylinder permanent template that a kind of self-locking connects, is included in the ultra-high performance concrete of prefabrication
Surrounding layer, being provided with the steel pipe of self-locking attachment structure at two ends, described ultra-high performance concrete surrounding layer is positioned at outer wall of steel pipe, phase
Adjacent ultra-high performance concrete cylinder permanent template is by fastener for connection, and described adjacent ultra-high performance concrete surrounding layer is in junction
Cast-in-place ultra-high performance concrete is to form entirety.
Further, described ultra-high performance concrete surrounding layer flushes with outer wall of steel pipe upper end, and the lower end of steel pipe is stretched out super
High performance concrete surrounding layer 200 ~ 300mm, described ultra-high performance concrete surrounding layer two ends are all reserved cast-in-place very-high performance and are mixed
The inclined-plane of solidifying soil.
Further, described steel pipe upper end inwall arranges cross section is trapezoidal helical form inner slope rib.
Further, outside the pipe of described steel pipe lower end connect tubular ribbed steel, described ribbed steel outer wall be provided with
The cross section that described helical form inner slope rib matches is trapezoidal helical form outer slope rib.
Further, described inner slope rib and rib surface, outer slope painting lubricating oil, slope angle θ of rib and skin-friction coefficient μ should
Meet relation: tan θ > μ.
Present invention also offers the construction of the ultra-high performance concrete cylinder permanent template that a kind of described self-locking connects
Method, including step: when locating template, arranges a small amount of diagonal brace to keep the stability of permanent template；Outside described concrete
Covering is cast-in-place ultra-high performance concrete at reserved inclined-plane, and carries out vibration compacting with vibrating spear, and complete before concrete hardens
Become splicing；Described cylinder permanent template crane is directed at, to ensure that the trapezoidal finned surface at the two ends of docking is at same vertical
On line, the most slowly place；Under gravity, superposed cylinder permanent template will screw in lower cylindrical permanent template,
Check that docking is the most accurate；After concrete surface hardens, answer wetted surface and enclose with plastic foil, to prevent water from dividing evaporation mixed
Solidifying soil shrinks excessive, causes the ultra-high performance concrete of junction to ftracture.
Compared to currently used permanent template and common templates, it has the advantage that
Cross-brace greatly reduces, and speed of application is fast, and easy construction uses manpower and material resources sparingly.
Intensity is high, and crack resistance is strong, effectively protects inner concrete.
Being prefabricated in the factory, industrialization degree is high, and quality is guaranteed.
Corrosion resistance and impermeability are superior, have good durability.
Template is lighter, and size is less simultaneously, convenient transport, can carry out the splicing of length direction, good integrity.
Enhance anti-seismic performance and the impact flexibility of structure, reduce the accidental load damage to structure, improve structure reliable
Degree.
Protective layer heat-proof quality is good, and refractory ability is strong.
Due to the constraint of ultra-high performance concrete permanent template and share, structural-load-carrying capacity improves, simultaneously
Integrally-built ductility increases, and fragility reduces.
