Description

Severe cold area large area wing square stone material is mated formation prevention and cure of crack method

Technical field

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

Background technology

The severe cold area winter summer temperature difference reaches to spend 100 more, and the square stone material surface layer that some have 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.

Summary of the invention

It is an object of the invention to provide a kind of easy construction, effective severe cold area large area wing square stone material paving Dress prevention and cure of crack method.

The technical solution of the present invention is:

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

(1) granite face typesetting, expansion joint position determine

Use cad technique to carry out row's plate of granite face abnormity slabstone, determine between size and the stone material of every block of trapezoidal stone material Gap size, it is ensured that effect of mating formation, adjusts substrate concrete expansion joint (E.J.) spacing simultaneously in the range of 15~20m, adjusts in the range of 3~4m Integral basis layer concrete contracting kerf spacing, it is ensured that substrate concrete expansion joint (E.J.) is corresponding with facing expansion joint position with the position of contracting seam;Root Determining every piece of trapezoidal stone material size according to desk-top publishing figure, factory process is also numbered, and prevents on-the-spot with mixed;

(2) substrate concrete construction

Substrate concrete thickness is 200, uses C25 commerical ready-mixed concrete, and ground transport pump, Manual, machinery vibrate, three roll shafts Evener leveling, grooving machine joint-cutting;

Construction technology: inspection basic unit → surveying setting-out → installation form → concrete pumping → pave → flatten → plucking that vibrates → Joint-cutting → health preserving;

Substrate concrete construction formwork uses the channel-section steel that rigidity is enough, and side sets stayed mast and inserts hole;The height of steel form is base Layer concrete design thickness, template length is 3~5m, supporting adn fixing device at every meter of template-setup 1, mold plate verticality chock Wedge method adjusts, and construction joint indwelling is at expansion joint (E.J.);

According to predetermined stretching, contract seam position, when xoncrete structure base layer construction, first bury upper 25 thickness according to expansion joint (E.J.) position Soaking the Pinus koraiensis expansion joint plate of Colophonium, centre sets Φ 16mm dowel steel, spacing 200;

When concrete is unhardened, reject the concrete on expansion joint plate top, embed the batten of 20 × 20, flattened faces, expansion joint (E.J.) Plate should continuous through whole substrate concrete, expansion joint plate is vertical with Lu Zhizheng line, and slotted wall is vertical;

Dowel steel employing Φ 16mm reinforcing bar, spacing 200, a length of 700, the surface of more than half length should be coated with anti-stick Layer, end should be worn movable cap bag, be overlapped cap material and use Φ 20mm plastic tube, end employing asphalt felt to seal blocking, dowel steel steel Muscle processing should be sawed-off, cut-out must not be extruded, fracture should vertically, light justify, fall burr with grinder buffing, and be processed into 2~3 roundings Angle;

All vertical, horizontal contracting seam all uses the construction of joint-cutting method, and the joint-cutting degree of depth is 6, and width is 10, first arrives with thin saw blade sawing Require the degree of depth, re-use 6~8 thick saw blades or overlapping saw blade widens joint filling groove;

With the covering wet curing such as gunnysack, straw screen or mat and sprinkle water in time, keep concrete surface to be in dampness, basic unit all the time At the concrete curing initial stage, forbidding pedestrian, vehicle pass-through, after reaching design strength 40%, pedestrian can pass through;

(3) surface layer paving control line construction

According to stone material surface layer every block of trapezoidal stone material of CAD typesetting figure and gap size, every section of circle and the center of circle of circular arc, use total powerstation Orient the radial direction control line of each every block of stone material of section, use chord off-set method to survey the broadwise control line setting every block of stone material, and By the radial direction of every block of trapezoidal stone material and broadwise control line line of ink marker bullet on concrete base layer, as depending on of every piece of stone material paving According to;

(4) granite face is mated formation

Granite panel of mating formation is 40 thick fired slab floor file, and on C25 concrete base layer, first brush plain-water slurry one time, then adopts With 20 thick 1:2.5 cement mortar screedings, panel and basic unit use 50 thick 1:2.5 dry cement mortar binder courses, fired slab 5 thick plain-water slurry tack coats are scraped in bottom surface;

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

Using and expansion joint plate equal thickness when surface layer is mated formation, height is embedded at expansion joint plate with the batten of binder course uniform thickness of mating formation, With paving with dragging, it is ensured that without mortar between expansion joint plate and surface layer, gap-filling glue after having mated formation, is used to fill up;

(5) filleting

Expansion joint of mating formation uses PVC cement, first uses grooving machine to remove in seam sandstone, the mortar etc. of condensation being mingled with, Re-use the pressure press water more than 0.5Mpa and compressed air thoroughly removes the dust in seam and other pollutant, it is ensured that seam Wall and cleaning inside, it is dried.Slotted wall is checked can not wipe dust for cementation of fissures standard;

Crack pouring depth is at 15~20 mm, and the most shallow 15 mm that cannot be less than, first extruding embeds diameter 9~12 mm sponge plastics Backing strip, then cementation of fissures cementation of fissures end face should flush with plate face;Necessary full, uniform, the consistency of thickness of joint filling is the most through, joint sealing material Must not lack, ftracture and seep water

Stone material surface layer except expansion joint is with in addition to PVC cement filleting, other all gaps the most not filletings, drop in gap The foreign material such as cement mortar to clean out.

Easy construction of the present invention, effective.Save maintenance cost.

Below in conjunction with embodiment, the invention will be further described.
