Description
Technical field
The invention belongs to building structure technology field, and in particular to a kind of quick assembled type pipe constrains prestressed component.
Background technology
Now, accidental pollution event is increasingly subject to pay attention to, and building temporary building turns into the important content of rebuilding in disaster-hit areas.
Temporary building can make place conversion according to different use demands, move in whole or in part, and simultaneously can simple group
Dress.After the mission that temporary building completes it, construction material is just changed into permanent key element, and this is just to building temporary building
Material propose ecological requirements higher, in temporary building construction material should from feedstock capture, the manufacture of product, applied
Four aspects such as journey and the recycling after are accounted for.Post component is the main bearing member in temporary structure, if
Crucial post component is destroyed, or even can cause the continuous collapse of structure, and the life and property to the people bring potential safety hazard.Pass
The post component of system is frequently with reinforced column, steel-concrete coupled column or steel column, cost in reinforced column building course
It is minimum, but due to needing the operations such as formwork, form removal, therefore speed of application is slow and should not remove, and is not suitable for temporary building.Steel-
Concrete combination column has the advantages that high capacity, anti-seismic performance be good, speed of application is fast, for that can play it in temporary building
Mechanical property advantage, but the temporary building for needing to remove, due to causing component to be difficult to remove after concrete hardening, therefore
Also it is less suitable for use in provisional component.For steel structure member, because steel member fire resistance is poor, the low shortcoming of rigidity, use
Certain defect is there is also in temporary building.
The content of the invention
The purpose of the present invention is to solve conventional steel bar concrete post, steel-concrete coupled column and steel column for provisional
The defect of building, proposes a kind of quick assembled type pipe constraint prestressed component, including outer tube, internal packing material, prestressing force
Muscle, sleeve pipe, end plate and nut.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of quick assembled type pipe constrains prestressed component, including presstressed reinforcing steel, outer tube, and outer tube upper and lower side is respectively equipped with end
Plate, upper and lower end plate is provided with not equal diameter bolt hole, and in the screwed presstressed reinforcing steel plug-in-sleeve in end, two ends connection is upper and lower
Installation nut in end plate upper bolt hole, outer tube inside and inside are provided with outside the sleeve pipe of presstressed reinforcing steel and set internal filling material
Material；
Described nut of tightening applies pretightning force to presstressed reinforcing steel, and the internal packing material of compression makes component form entirety and receives jointly
Power.
Described end plate can contact with outer tube or leave gap.
Described outer tube uses circular, rectangle or polygonal cross-section, using stainless steel tube, common steel tube, stainless steel double
Close pipe or FRP pipes.
Described inside packing material uses sand, soil or other powdery fillers.
Described sleeve pipe uses plastic bushing, steel sleeve or FRP sleeve pipes.
Described end plate can use general steel plate or stainless-steel sheet, and described end plate cross section is convex.
The beneficial effects of the invention are as follows：
The present invention in advance should using outer tube and the compound action of internal packing material by applying longitudinal direction to internal packing material
Power, makes internal packing material produce transversely deforming, and outer tube is in hoop tension state, and energy operative constraint internal material makes at it
In three dimension stress state, bearing capacity, ductility and the energy dissipation capacity of component are significantly improved.Such component is relative to traditional reinforced concrete
Native component, has the advantages that speed of application is fast, high capacity, anti-seismic performance are good；Relative to steel-concrete combined member, have
The characteristics of convenient disassembly, after component is removed, unloading is applied to the prestressing force on internal packing material, and internal material can conveniently take
Go out, so as to realize the recycling of outside tubular construction and internal material；Relative to traditional steel components, with rigidity is big, bearing capacity
It is high, the advantages of fire resistance is good, therefore quick assembled type pipe constrain prestressed component have in temporary building it is wide should
With prospect, simultaneously because its superior mechanical property, can also use as permanent component.

Specific embodiment
The present invention is further discussed below with reference to accompanying drawing.
As shown in Figure 1, 2, 3, a kind of quick assembled type pipe constraint prestressed component, including presstressed reinforcing steel 1, outer tube 3, its
It is characterised by, the upper and lower side of outer tube 3 is respectively equipped with end plate 5, upper and lower end plate 5 is provided with not equal diameter bolt hole 7, and end carries spiral shell
In the plug-in-sleeve 2 of presstressed reinforcing steel 1 of line, two ends connect the installation nut 6 in the upper and lower upper bolt hole 7 of end plate 5, inside outer tube 3
And inside is provided with the internal packing material 4 of outer setting of sleeve pipe 2 of presstressed reinforcing steel 1；
Described nut 6 of tightening applies pretightning force to presstressed reinforcing steel 1, and the internal packing material 4 of compression forms component overall common
Stress.
Described end plate 5 can contact with outer tube 3 or leave gap.
Described outer tube 3 uses circular, rectangle or polygonal cross-section, using stainless steel tube, common steel tube, stainless steel double
Close pipe or FRP pipes.
Described inside packing material 4 is using sand, soil or other powdery fillers.
Described sleeve pipe 2 is using plastic bushing, steel sleeve or FRP sleeve pipes.
Described end plate 5 can use general steel plate or stainless-steel sheet, and the described cross section of end plate 5 is convex.
Operation principle of the invention is：
First by the screwed plug-in-sleeve 2 of presstressed reinforcing steel 1 in end；Then the presstressed reinforcing steel 1 with sleeve pipe 2 is put into outer
In layer pipe 3, the bottom plate 5 with predetermined bolt hole is fixed on the bottom of outer tube 3, prestressing force is fixed using nut 6 is installed
Muscle 1, end plate 5 can make variable cross-section form shown in Fig. 3, in the less insertion of a side end panel 5 outer tube 3 in section, be opened up on end plate 5
Not equal diameter bolt hole 7；Then internal packing material 4 is filled into outer tube 3, by the upper head plate 5 with predetermined bolt hole
The top of outer tube 3 is arranged on, nut 6 then is installed on the top of presstressed reinforcing steel 3, nut 6 is placed in bolt hole 7, tightens nut 6
Pretightning force is applied to presstressed reinforcing steel 1, so as to compress internal packing material 4, being applied to after predetermined pretightning force can completion component
Install, component is formed overall common stress.
The method is the packing material in pipe, applies prestressing force by internal packing material, using outer tube to inside
The effect of contraction of packing material, makes component have bearing capacity and good fire resistance higher, easy to disassemble, while realizing outer
Manage the recycling with internal material in portion.Specific implementation method：After packing material in pipe, by the presstressed reinforcing steel set in pipe
Prestressing force is applied to core filler material, according to the demand using function, exterior tube can undertake part vertical load or not undertake
Vertical load, after prestress application is finished and end plate is fixed, that is, forms overall primary structure member.The present invention is applied to temporary building
Post component can also be used for permanent post component, component has the advantages that high capacity, anti-seismic performance are superior, and in component own
Part can be reused, with preferable economic benefit.
