Description

Large area wing square stone material in severe cold area is mated formation prevention and cure of crack method

Technical field

Mat formation prevention and cure of crack method the present invention relates to a kind of wing square stone material of severe cold area large area.

Background technology

The severe cold area winter summer temperature difference reaches to be spent more 100, some square stone material surface layers built up, due to summer in winter huge temperature Difference deformation, by drawing crack, breaks, have impact on the use on square, how to prevent the generation of wing square stone material top-crack, be one Important topic.

The content of the invention

It is an object of the invention to provide a kind of large area wing square stone material paving in severe cold area easy for construction, that effect is good Fill prevention and cure of crack method.

The present invention technical solution be:

A kind of wing square stone material of severe cold area large area is mated formation prevention and cure of crack method, it is characterized in that:Comprise the following steps:

(One)Granite face typesetting, expansion joint position determine

Row's plate of granite face abnormity slabstone is carried out using cad technique, determines the size and stone material of every block of trapezoidal stone material Between gap size, it is ensured that effect of mating formation, at the same in the range of 15~20m adjust substrate concrete expansion joint (E.J.) spacing, 3~4m scopes Interior adjustment substrate concrete contracting seam spacing, it is ensured that the position of substrate concrete expansion joint (E.J.) and contracting seam is opposite with facing expansion joint position Should;Every piece of trapezoidal stone material size is determined according to desk-top publishing figure, factory process is simultaneously numbered, and it is mixed to prevent that scene from using;

(Two)Substrate concrete is constructed

Substrate concrete thickness is 200 ㎜, and using C25 commerical ready-mixed concretes, ground pump conveying, Manual, machinery are vibrated, three The leveling of roll shaft evener, grooving machine joint-cutting;

Construction technology:Check basic unit → surveying setting-out → installation form → concrete pumping → pave → leveling → vibrate drawing Hair → joint-cutting → health;

For substrate concrete construction formwork using the enough channel steels of rigidity, side sets stayed mast insertion hole;The height of steel form For substrate concrete design thickness, template length is 3~5m, and supporting adn fixing device at every meter of template-setup 1, mold plate verticality is used Chock wedge method adjusts, and construction joint indwelling is at expansion joint (E.J.);

According to it is predetermined stretch, contract seam position, in concrete structure base layer construction, upper 25 are first buried according to expansion joint (E.J.) position ㎜ thickness soaked the Korean pine expansion joint plate of pitch, and centre sets Φ 16mm transmission rods, 200 ㎜ of spacing;

When concrete is unhardened, the concrete on rejecting expansion joint plate top, the batten of embedded 20 × 20 ㎜, flattened faces, Expansion joint plate should continuously penetrate through whole substrate concrete, and expansion joint plate is vertical with Lu Zhizheng line, and slotted wall is vertical;

Transmission rod uses Φ 16mm reinforcing bars, 200 ㎜ of spacing, and length is 700 ㎜, the surface of more than half length should apply anti-sticking Layer is tied, end should wear movable cap bag, and set cap material uses Φ 20mm plastic tubes, and end is blocked using asphalt felt sealing, transmission rod Steel bar meter should be sawed-off, must not extrude cut-out, and fracture is answered vertical, light circle, pierced with grinder buffing hair loss, and be processed into 2~3 ㎜ and fall Fillet;

All vertical, horizontal contracting seams are constructed using joint-cutting method, and joint-cutting depth is 6 ㎜, and width is 10 ㎜, is first sawed with thin saw blade Switch to and require depth, reuse 6~8 ㎜ thickness saw blades or overlapping saw blade broadening joint filling groove;

Sprinkle water with the covering such as gunnysack, straw screen or mat wet curing and in time, keep concrete surface to be in dampness all the time, Substrate concrete health initial stage, forbid pedestrian, vehicle pass-through, after design strength 40% is reached, pedestrian can pass through;

(Three)Surface layer paving control line is constructed

According to stone material surface layer CAD typesettings figure every block of trapezoidal stone material and gap size, the center of circle of every section of circle and circular arc, using complete Instrument of standing orients the radial direction control line of each every block of stone material of section, and the broadwise control for setting every block of stone material is surveyed using chord off-set method Line, and by the radial direction of every block of trapezoidal stone material and broadwise control line with line of ink marker bullet on concrete base layer, as every piece of stone material paving Foundation;

(Four)Granite face is mated formation

Granite panel of mating formation is 40 ㎜ thickness fired slab floor file, first brush plain-water slurry one time on C25 concrete base layers, so 20 ㎜ thickness 1 are used afterwards:2.5 cement mortar screedings, panel use 50 thickness 1 with basic unit:2.5 dry cement mortar binder courses, fire Burn plate bottom surface and scrape 5 ㎜ thickness plain-water slurry tack coats;

Granite face stays at substrate concrete expansion joint (E.J.) and expansion joint sets 10 ㎜ wide expansion joints;

Used when surface layer is mated formation and be embedded in expansion joint plate with expansion joint plate equal thickness, the highly batten with binder course uniform thickness of mating formation Place, with paving with dragging, it is ensured that without mortar between expansion joint plate and surface layer, filled up after the completion of mating formation using gap-filling glue;

(Five)Filleting

Expansion joint of mating formation uses PVC cement, first removes the sandstone being mingled with seam, the sand of condensation using grooving machine Slurry etc., reuses pressure water of the pressure more than 0.5Mpa and compressed air thoroughly removes dust and other pollutants in seam, Ensure slotted wall and cleaning inside, drying.Slotted wall is examined can not wipe dust as cementation of fissures standard;

Crack pouring depth is in 15~20 mm, most shallow to cannot be less than 15 mm, first extruding insertion 9~12 mm porous foams of diameter Plastic backings bar, then cementation of fissures cementation of fissures top surface should be flushed with plate face;Joint filling full, uniform, consistency of thickness and must be penetrated through continuously, be filled out Sewing must not lack, cracks and seep water

Stone material surface layer is except expansion joint is with addition to PVC cement filleting, other have the gap not filleting, in gap The debris such as the cement mortar to drop will be cleaned out.

The present invention is easy for construction, effect is good.Save maintenance cost.

With reference to embodiment, the invention will be further described.
