Abstract
The invention discloses a method for preventing seams of new and old walls from cracking. The method comprises steps as follows: a, a groove is formed in an old wall; b, a new wall perpendicular to the groove is built; c, cement mortar rendering is performed on the groove and the new wall, and the width of the groove is larger than the thickness of the new wall. The groove is formed in the old wall, so that after the new wall is constructed outwards from one side of the groove, rendering of the new wall is started from the groove, accordingly, the new and old walls can be rendered in a unified manner at the connection corners of the new and old walls, stress concentration in the connection position of the new and old walls during rendering is reduced, cracks are prevented from being formed between the new wall and the old wall after rendering, the integrity of the whole wall is improved, shedding of rendering substances is prevented, and the use safety is guaranteed.
Description
Technical field
The invention belongs to the realm of building construction, especially relate to a kind of new and old wall seam crossing crack resistence method.
Background technology
By house again layout in life, isolate the room made new advances very common, new wall againsts old wall construction, whitewashes after having built to new wall again.After new calcimine brush completes, after cement, lime etc. are air-dry, occur crack at the intersection of Xin Qiang and old wall, have impact on overall attractive in appearance, and after there is crack, whitewashing thing and may occurring coming off of new wall, uses unsightly with dangerous.
Summary of the invention
The object of the present invention is to provide the new and old wall seam crossing crack resistence method of at least one in a kind of can solving the problem.
According to an aspect of the present invention, provide a kind of new and old wall seam crossing crack resistence method, comprise the following steps:
A, on old wall, offer groove;
B, the new body of wall of vertical above-mentioned groove construction;
C, cement sand plaster is carried out to groove and new body of wall;
The width of described groove is greater than the thickness of new body of wall.
The invention has the beneficial effects as follows: owing to offering groove on old wall, therefore after new body of wall has outwards been built from groove side, to new wall plastering from groove, thus enable new and old body of wall unify to whitewash in connection corner, reduce concentrating of stress when new and old wall junction is whitewashed, between new body of wall and old wall, form crack after preventing from whitewashing, improve the globality of whole body of wall, prevent and whitewash thing and come off, ensure safety in utilization.
In some embodiments, groove inwardly digs out from the end face of old wall, the consistency of thickness of the degree of depth of groove and the cement layer of old wall end face.Thus, facilitate offering of groove, and when being convenient to follow-up whitewashing, Jiu Qiang and new wall connecting place all can unify to whitewash.
In some embodiments, new body of wall and Jiu Qiang junction are provided with reinforcing bar, thus, ensure that and ensure that the intensity of new body of wall by the steadiness that both connect.
In some embodiments, the both sides of new body of wall and groove junction are provided with L-type gauze wire cloth.Thus, add the intensity of new body of wall and Jiu Qiang junction, the transmission of whitewashing the active force of thing be on the corner subject to both convenient.
In some embodiments, the width large 20cm more every than the thickness of new body of wall of groove, new body of wall is positioned at the centre of groove.Thus, be convenient to the construction of new body of wall, and the uniformity that when conveniently whitewashing, new and old wall connecting place is whitewashed.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of new and old wall seam crossing crack resistence method of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
With reference to Fig. 1, new and old wall seam crossing crack resistence method of the present invention, comprises the following steps:
A, on old wall 1, offer groove 2, groove 2 inwardly digs out from the end face of old wall 1, the consistency of thickness of the degree of depth of groove 2 and the cement layer of old wall 1 end face, when offering groove 2, being hit down by the part rendering layer formerly on old wall 1, and cleaning out to dustless state;
B, vertical above-mentioned groove 2 build new body of wall 3, and new body of wall 3 is close to the bottom end face construction of groove 2;
C, carry out cement sand plaster to groove 2 and new body of wall 3, when plaster, the consistency of thickness whitewashing thing on the thickness of plaster layer 6 and original old wall, fills and leads up groove 2 part when namely whitewashing, maintains the planarization of body of wall.
The width of groove is greater than the every limit 20cm of thickness of new body of wall.
New body of wall 3, when building, inserts reinforcing bar at groove 2 place, and namely new body of wall 3 is provided with reinforcing bar 4 with old wall 1 junction, ensure that the bonding strength of new body of wall 3 with old wall 1 and the steadiness of new body of wall 3.The bar construction layer in old wall 1 is inserted in one end of the reinforcing bar 4 of both seam crossings, reinforcing bar 4 is fixed within the walls old; The other end of reinforcing bar 4 inserts in new body of wall 3, and the other end of reinforcing bar 4 carries out coated by new body of wall 3, makes reinforcing bar 4 play booster action to new body of wall 3.
Both sides and groove 2 junction of new body of wall 3 are provided with L-type gauze wire cloth 5.One end of L-type gauze wire cloth 5 is arranged in groove 2, is fixed in groove 2 by concrete or cement; The other end is fixed on new body of wall 3 by plaster layer 6.Be provided with L-type gauze wire cloth 5, after new body of wall 3 and old wall 1 can be facilitated to whitewash, the transmission of the active force of two sides body of wall, decreases stress to a great extent and concentrates at two sides body of wall intersection, prevents the follow-up thing that whitewashes to produce crack at two sides body of wall seam crossing.
After L-type gauze wire cloth 5 fixedly completes, carry out plaster to groove 2 and new body of wall 3, during plaster, plaster layer 6 is just mutually concordant with the upper surface of groove 2, makes old wall 1 keep smooth.Groove 2 place and the new body of wall 3 of old wall 1 whitewash simultaneously, two places to whitewash thing drying time consistent, effectively prevent new and old two sides body of wall and produce crack at seam crossing.
The width on one side large 20cm more every than the thickness of new body of wall 3 of groove 2, new body of wall 3 is positioned at the centre of groove 2, and namely the distance of the side of the new corresponding groove 2 of body of wall 3 liang of lateral extents is 20cm.Thus, ensure that two sides of new body of wall 3 and groove 2 part of old wall 1 all can be whitewashed simultaneously, facilitate two sides body of wall seam crossing to seamlessly transit, the generation of crackle preventing.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
