Abstract
The invention relates to a self-shearing pin for heat-insulation building formworks. The self-shearing pin is suitable to be used as a fixing connector for the heat-insulation building formworks and wood ridges of connecting formwork frames and comprises an iron pin, a modified ABS (acrylonitrile butadiene styrene) pin rod and an adhesive layer. The rear end of the iron pin is adhered with the front end of the modified ABS pin rod by the adhesive layer, a conical pin head is arranged at the front of the iron pin, and a conical connecting head is arranged at the rear end of the iron pin; a pin cap is arranged at the rear end of the modified ABS pin rod, a pin rod is arranged in the middle of the modified ABS pin rod, and a conical connecting fork is arranged at the front end of the modified ABS pin rod; water guide grooves are formed in the conical connecting fork; a center water guide hole is formed in the center of the pin rod and is communicated with the water guide grooves formed in the conical connecting fork.
Description
Technical field
The present invention relates to a kind of building heat preservation template is from broken nail it is adaptable to making building heat preservation template and being connected pattern plate bolster
Frame wood stupefied fixedly connected part.
Background technology
At present building heat preservation template is fixedly connected with being connected template framework wood stupefied, using being definitely fixedly connected, concrete
After casting complete, template framework wood stupefied needs to remove, and can damage building heat preservation template during removing wood stupefied, so that heat insulation formwork is resisted
Pressure, insulation, water resistance decline, and can affect monolithic architecture construction quality.
Content of the invention
The present invention is directed to above-mentioned weak point and provides a kind of building heat preservation template from broken nail, from broken nail rear portion using modified
ABS（Engineering plastics）Nail rod, is connected with iron nail by gluing oxidant layer, building heat preservation template be connected template framework wood stupefied using building
Build heat insulation formwork, from broken nail, fixation is installed, building heat preservation model sheetinstallat finishes, and can pour into a mould concrete, by vibration-extrusion coagulation
Water more than local products alkalescence concrete, after center water-guiding hole, guiding gutter flow to Aci-Jel adhesive layer 48-72 hour, gluing oxidant layer
The sixth of the twelve Earthly Branches is corroded and loses adhesion strength, loses adhesion strength from the gluing place of broken nail and automatically disconnects.Building heat preservation mould now can be removed
Plate framework wood stupefied, modified ABS nail rod is partially left in building heat preservation template and reaches self-enclosed effect, and iron nail is with this stupefied dismounting.
Building heat preservation mould takes technical scheme below to realize from broken nail：
Building heat preservation mould includes iron nail, modified ABS nail rod and gluing oxidant layer from broken nail；Iron nail rearward end is followed closely with modified ABS
Bar leading section adopts gluing oxidant layer bonding, and described iron nail front portion is provided with taper ailhead, and iron nail rearward end is provided with cone
Union joint.
Described modified ABS nail rod rearward end is provided with the head of a nail, middle part is provided with nail rod, leading section is provided with cone connection
Fork, cone connects fork and is provided with guiding gutter, and guiding gutter is at least provided with 2.
Nail rod is provided centrally with center water-guiding hole, and center water-guiding hole is connected the guiding gutter connection of fork setting with cone.
The head of a nail and center water-guiding hole junction are provided with taper chamfering, prevent from boring nail hitting cap deformation obstruction from broken nail when installing
Center guide hole.
Described gluing oxidant layer adopts Aci-Jel adhesive layer, pH value 3-5, water pH value more than concrete in concrete placement
For 11-13, in alkalescence, more than alkaline concrete, water can corrode thawing Aci-Jel adhesive layer at leisure.
Building heat preservation template is reasonable in design from broken nail, and compact conformation is easy to use, during use building heat preservation template be connected
Template framework wood stupefied adopts building heat preservation template to install from broken nail and fixes, and iron nail part squeezes into wood stupefied by building heat preservation template,
Modified ABS nail rod is partially left in building heat preservation template, and building heat preservation model sheetinstallat finishes, and can pour into a mould concrete, by shaking
Dynamic extruded concrete produces water more than alkaline concrete, flows to Aci-Jel adhesive layer by center water-guiding hole, guiding gutter, little through 48-72
Shi Hou, gluing oxidant layer the sixth of the twelve Earthly Branches is corroded and loses adhesion strength, loses adhesion strength from the gluing place of broken nail and automatically disconnects.Now can tear open
Except building heat preservation template framework wood stupefied, modified ABS nail rod is partially left in building heat preservation template and reaches self-enclosed effect, iron nail with
This stupefied dismounting.Building heat preservation template is particularly well-suited to make building heat preservation template from broken nail and is connected template framework wood stupefied and is fixedly connected
Part.
Brief description
Below with reference to accompanying drawing, the invention will be further described：
Fig. 1 is that building heat preservation template is autotomyed pin structure schematic diagram.
Fig. 2 is the head of a nail structural representation from broken nail for the building heat preservation template.
Fig. 3 is that building heat preservation template is adopted at adhesive bonds from the iron nail rear end of broken nail with modified ABS nail rod leading section
Schematic diagram.
Specific embodiment
Referring to the drawings 1～3, building heat preservation mould includes iron nail 1, modified ABS nail rod and gluing oxidant layer 3 from broken nail；After iron nail 1
End is bondd using gluing oxidant layer 3 with modified ABS nail rod leading section, and described iron nail 1 front portion is provided with taper ailhead 2, iron nail 1
Rearward end is provided with conical union joint 9.
Described modified ABS nail rod rearward end is provided with the head of a nail 6, middle part is provided with nail rod 4, leading section is provided with cone even
Connect fork 7, cone connects fork 7 and is provided with guiding gutter 10.
Nail rod 4 is provided centrally with center water-guiding hole 5, and center water-guiding hole 5 is connected the guiding gutter 10 of fork 7 setting even with cone
Logical.
Described cone connects the guiding gutter 10 of fork 7 at least provided with 2.
The head of a nail 6 and center water-guiding hole 5 junction are provided with taper chamfering 8, prevent from boring nail hitting cap 6 when installing from broken nail and deform
