Description
Technical field
The present invention relates to a kind of post mould template construction structure, especially a kind of minor diameter high-fineness ratio clear-water concrete bundle pillar
Formwork structure.
Background technology
With the continuous innovation of Building technology, meeting on the premise of it uses function, modern design, with conspicuous characteristics builds
Build the favor that design techniques increasingly obtain architect.In clear-water concrete field, a kind of clear water of minor diameter high-fineness ratio is mixed
Solidifying soil cylinder starts progressively to be applied in building structure, and this clean water column generally has diameter small, and height height, quantity is more, it is desirable to
Tight the characteristics of.
Construction of the existing mould plate technique to fair-faced concrete cylindrical is typically with customization punching block or customization wooden model, steel
Mould is heavy, and cost is big, unsuitable large-area construction.Wooden model is that two pieces of left and right is connected into after entirety, but form removal generally by concavo-convex draw-in groove
At wooden model draw-in groove and wooden model joint one flickering vertical vestige of formation can be segmented, cause faced concrete surface to see
Sense is second-rate.
The content of the invention
Goal of the invention：There is provided it is a kind of facilitate fair-faced concrete cylindrical concrete construction and form removal after surface there is no the post of convex epirelief
Mode structure.
Technical scheme：Minor diameter high-fineness ratio clear-water concrete bundle pillar formwork structure of the present invention, including template branch
Support frame frame, bottom limit assembly, docking strengthening mechanism and about at least two PVC post moulds for docking；
Shuttering supporting framework is the rectangular frame of vertical vertical rod, vertical equity bar and transverse horizontal bar composition；
The midpoint of two vertical equity bars and two transverse horizontal bars at upper and lower two PVC posts mould docking height is vertically provided with one
Root support rail；
Bottom limit assembly includes limiting plate and at least three position limiting piles；Position limiting pile is close to be arranged on limiting plate
Around, it is provided with central socket in the center of limiting plate；The lower edge of bottom PVC post moulds inserts in the central socket of limiting plate
It is interior；
Docking strengthening mechanism include four pieces of limiting plates, two Screw arbor with nut at both-ends, four U-shaped cards seats, four fixing nuts and
Four are shored；Semicircular notch is equipped with the side edge of every piece of limiting plate, two-by-two the semicircular notch split of limiting plate
Holding sheet in the middle of holding sheet in the middle of two, two is constituted afterwards is clamped in two abutting edges of PVC post moulds for docking up and down respectively
Place；Two Screw arbor with nut at both-ends are set in parallel in the middle of upper and lower two between holding sheet；Four U-shaped card seats are respectively sleeved at two to drawing
On four terminations of screw rod, and each U-shaped card seat is withheld on upper and lower two ipsilateral penumbras of middle holding sheet simultaneously；Four
Fixing nut is screwed on two the four of Screw arbor with nut at both-ends terminations respectively, so as to clamp four U-shaped card seats；Shore for four and prop up respectively
Support the top of four support rails and it is upper and lower two in the middle of holding sheet four side edge between.
Using shuttering supporting framework can provide the support of transverse direction and longitudinal direction for docking strengthening mechanism, be whole formwork structure
Basic supporting construction；The lower end of the PVC post moulds of bottommost can be carried out using limiting plate spacing, and utilize position limiting pile
Carry out position to fix, displacement occurs in PVC post moulds lower end in preventing work progress, it is ensured that the accuracy of PVC posts mould construction；Using limit
Position plate constitutes middle holding sheet, simultaneously fixed so as to be carried out to the two post moulds for docking up and down, is prevented effectively from construction joint and is formed
The problem of faulting of slab ends convex epirelief；The opposite side of holding sheet in the middle of two is gripped using Screw arbor with nut at both-ends and U-shaped card seat, effectively
Ensure holding sheet consistency from top to bottom in the middle of two, so as to ensure the two post die orifice consistencies from top to bottom for docking up and down indirectly, further keep away
Exempt from the problem of formation faulting of slab ends convex epirelief at construction joint.
Scheme, docks strengthening mechanism also including four pieces of pressure-bearing limiting cushion blocks as a further improvement on the present invention；Four pieces are held
Pressure limiting cushion block is separately positioned at four drift angles in the middle of upper and lower two between holding sheet.Using pressure-bearing limiting cushion block to upper and lower
It is supported at four drift angles in the middle of two between holding sheet, has both ensured the integral thickness of holding sheet in the middle of upper and lower two, is made
Clamping is tight between holding sheet and U-shaped card seat in the middle of upper and lower two, prevents the upper and lower play of middle holding sheet, and upper and lower two can be made again
Individual middle holding sheet is isolated, and the abutment joint state of upper and lower two docking post mould is conveniently watched, so as to adjust make at abutment joint
Dock completely, honeycomb and pitted skin are formed so as to be prevented effectively from construction abutment joint.
As further limits scheme of the invention, shore including spiral expanding bar and be separately positioned on spiral expanding bar
The supporting plate and U-shaped card support at two ends；Supporting plate is supported on the top of support rail, and U-shaped card support is withheld in upper and lower two centres
On the ipsilateral penumbra of holding sheet.Withheld on upper and lower two edges of middle holding sheet using four U-shaped card supports, so that real
The support and positioning regulation of docking strengthening mechanism are now shored, the flexibility of construction is improve.
Scheme, is provided with bur on the supporting plate as a further improvement on the present invention；Bur inserts the top of support rail.
Can make to shore using bur to be contacted between support rail and more consolidate, improve the stability for shoring support.
Used as further limits scheme of the invention, fixing nut is mountain type fixing nut.Using mountain type fixing nut energy
Enough improve nut and fix efficiency of construction.
Compared with prior art, its advantage is the present invention：（1）It can be docking reinforcing machine to use shuttering supporting framework
Structure provides the support of transverse direction and longitudinal direction, is the basic supporting construction of whole formwork structure；（2）Can be to most using limiting plate
The lower end of the PVC post moulds of bottom carries out spacing, and carries out position using position limiting pile and fixes, and prevents in work progress under PVC post moulds
There is displacement in end, it is ensured that the accuracy of PVC posts mould construction；（3）Middle holding sheet is constituted using limiting plate, so as to docking up and down
Two post moulds carry out simultaneously fixed, be prevented effectively from construction joint and form the problem of faulting of slab ends convex epirelief；（4）Using Screw arbor with nut at both-ends and U
Type deck is gripped to the opposite side of holding sheet in the middle of two, effectively ensures holding sheet consistency from top to bottom in the middle of two, from
And the two post die orifice consistencies from top to bottom for docking up and down are ensured indirectly, further avoid being formed at construction joint the problem of faulting of slab ends convex epirelief.
