Description

A kind of method of attaching of architectural coating brick

Technical field

The present invention relates to building decoration engineering technical field of construction, specifically, relate to a kind of method of attaching of architectural coating brick.

Background technology

The method of attaching of traditional architectural coating brick is back of the body bonding, by the first full coat of binding material in the back side of face brick, is then sticked in body of wall basic unit.As at metope pasted with ceramic veneer face brick, because traditional back of the body bonding is at face brick back side full coat binding material, therefore binding material thickness is comparatively large, binding material consumption is also larger; In addition, traditional binding material utilizes cement, sand at building-site exactly, artificial batching, manually to stir, due to the difficult quality of the cement at scene, sand control, trace mineral supplement is difficult to add, proportioning is difficult to ensure, stir and be difficult to evenly, the total quality of binding material is made to be difficult to ensure, the phenomenon such as thus easily produce hollowing between face brick and metope, come off.

In order to reduce binding material consumption, improve efficiency of construction and workmanship, people have invented thin bonding, also referred to as trowel method or plaster application, during construction, first by binding material full coat in body of wall basic unit, then use sawtooth trowel by binding material combing one time, then by walltile pressing on it.The general sawtooth height of sawtooth trowel is 6mm, facewidth 6mm, space width 12mm; Tooth depth, the facewidth, space width also have and are respectively 8mm, 10mm, 12mm specification, and corresponding spacing also increases thereupon.After the combing of sawtooth trowel, paste face brick again, the thickness of tack coat can be reduced to 2 ~ 4mm, so be called thin bonding.Mostly thin bonding binding material used is the dry mixing cement mortar through polymer modification, and price is high compared with the traditional cement mortar of extemporaneous preparation, stirring.The feature of thin bonding is that binding material consumption is little, adhesive speed is very fast; But this method due to binding material full coat large to the area in body of wall basic unit, the operating time is longer, before sticky brick, binding material surface easily skinning and reduce adhesion stress, and facing turns and bond area between binding material is little, therefore, the overall adhesion strength of thin bonding is not high yet.Face brick adhesive method more advanced is at present " combined method ", also two-sided bonding is claimed, first by binding material full coat in body of wall basic unit, then use sawtooth trowel by binding material combing one time, the face brick then back side having been filled binding material sticks to trowel and is coated with in the body of wall basic unit of binding material." combined method " combines the advantage of " back of the body bonding " and " trowel method ", and binding material consumption is moderate, adhesion strength is high.But for specification, walltile that weight is larger, or the vitrified tile that water absorption rate is extremely low, even if adopt " combined method " to paste, also often there will be qualitative problems of construction.

Summary of the invention

Object of the present invention is exactly for specification, walltile that weight is larger, or the stickup of the extremely low vitrified tile of water absorption rate provides a kind of method, i.e. a kind of method of attaching of architectural coating brick.

The method of attaching realizing a kind of architectural coating brick of the present invention is as follows:

In the work progress that bonding applique surface turns in building masonry wall basic unit, first the back side of body of wall basic unit (1) surface and face brick (2) is cleaned out, then with plasterer's trowel by the binding material full coat for preparing in advance in body of wall basic unit (1), application area can be larger.At the back side of face brick (2), binding material is extruded furrow shape (see Fig. 1, Fig. 2), the binding material (3) of every bar furrow shape should be substantially vertical with ground after upper wall; Ridge is high depending on Base Smoothness, is 20 ~ 80mm; Ridge bottom width degree, depending on the specification of wall brick, is 80 ~ 100mm; Distance between the ridges is 0 ~ 100mm; The number on ridge is depending on the size of wall brick.Then use sawtooth trowel by the binding material combing in body of wall basic unit once, make the binding material of body of wall substrate surface form list structure bonding material layer (4) (see Fig. 3, Fig. 4).Then the face brick back side having been extruded furrow shape binding material (3) sticks to trowel and is coated with in the body of wall basic unit of binding material, make to increase one deck similar furrow shape bonding material layer (3A) between body of wall basic unit (1) and face brick (2), between body of wall basic unit (1) and face brick (2), namely have horizontal strip construction bonds material layer (4) of one deck and vertical similar furrow shape bonding material layer (3A) (see Fig. 5, Fig. 6).

By binding material full coat in body of wall basic unit (1), binding material and basic unit's secure bond can be made, with sawtooth trowel, combing is carried out to the binding material in basic unit, this layer thickness and material usage can be reduced, and prevent because its air spots causes work progress inconvenience; Advantage binding material being extruded furrow shape at the face brick back side is: one is that the height of furrow shape binding material can be increased arbitrarily according to Base Smoothness, empty sticky to prevent; Because space between ridge and ridge is comparatively large, the binding material exceeded can be extruded to the both sides on ridge, when avoiding completely gluing because subregion binding material is too high, be difficult to extrude, cause the phenomenon that jack-up herein, other regions void are sticky; Two is that the volumetric change of binding material in hardening process and the stress that therefore produces can discharge on the spot on the both sides on ridge, causes bonding failure after stress when avoiding completely gluing, strain accumulation are excessive; Three is because there is larger surface area on the both sides of ridge bar, and the larger surface tension formed thus can provide anti-preferably at the bonding initial stage and hang power from above, and face brick is not easily dropped; Four is that face brick moisture below or moisture can be discharged in time, thus improves adhesion strength; Five is can make to form secondary extrusion between binding material and wall brick, once from manually direct, binding material is extruded toward the brick back side when binding material being pressed on face brick ridge, secondary extrusion is brick brick extruding binding material when pasting in basic unit, thus effectively enhances the adhesion stress of face brick and binding material interface; Six is that the planeness of face brick is easy to adjust, and the existence in space between furrow, avoids the vacuum that may be formed when patch block post-tensioning moves face brick, makes, within the adjustable time, to draw more like a cork, press face brick; Seven is that effective bonding area can adjust arbitrarily as requested; Eight is effectively can save binding material, and because bonding failure is caused by interfacial failure often, the present invention, when strengthening effective bond area of interfacial adhesion and interface, maintains space between suitable ridge, binding material can effectively be saved; Nine is easy constructions.
