Abstract
The invention discloses a construction method for preventing vertical cracking between a main structure and a filled wall. After the construction of the main structure is finished, the construction of the filled wall is implemented; when the filled wall is constructed, the side surface of the filled wall in connection with the main structure is made into a zigzag structure; a tension rib in the filled wall penetrates a reserved combination column space to be connected with the main structure at the side surface; a combination column template is supported at the reserved combination column space, and plain concrete is poured and vibrated tightly to form a combination column; and the filled wall and the main structure are connected as a whole through the combination column. The plain concrete combination column is poured between the side surface of the filled wall and the main structure, and the combination column is connected with the main structure through the same material and engaged with the filled wall through the zigzag structure, therefore, the problem of cracking caused by insufficient engaging force between the main concrete structure and the filled wall and the shrinkage of the dissimilar materials of the wall is successfully solved; meanwhile, the combination column can effectively adjust the line snapping size and reduce the loss rate of the building blocks.
Description
Technical field
The present invention relates to a kind of building masonry wall job practices, particularly a kind of job practices that prevents vertical cracking between agent structure and the filled wall.
Background technology
At present, the cracking of wall surface of agent structure and filled wall junction is a common fault, and it is attractive in appearance that it influences metope, and the dispute, the complaint that relate to wall body slit and even seepage are more and more down to lawsuit, have accounted for more than 80% of workmanship complaint.This common quality defect that is ubiquitous has become very directly perceived, the responsive and primary quality specifications that the user passes judgment on construction quality.Although taked multiple strengthening measure at this position at present, the Crack Control resultant effect is not good, and this crack, position is repaired and had repeatability.Therefore formulate serial Prevention Technique measure, become the common problem of paying close attention to of the each side that takes part in building.
Summary of the invention
The present invention provides a kind of job practices that can prevent vertical cracking between agent structure and the filled wall for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of job practices that prevents vertical cracking between agent structure and the filled wall; May further comprise the steps: after 1) accomplishing the construction of agent structure; Before the construction filled wall, between filled wall side and agent structure, reserve the column space; 2) construction of completion filled wall; During the construction filled wall, its side that is connected with agent structure is built into horse tooth trough, the tension rib that is provided with in the filled wall connects the column space of passing reservation and is connected with the agent structure of one of which side; 3) install the column template at the place, column space that reserves, build the plain concrete vibration compacting and form column, filled wall and agent structure are linked into an integrated entity through column.
Said plain concrete is the microdilatancy plain concrete.
When said filled wall adopts hollow brick or porous brick to build by laying bricks or stones, the bleed-out silk screen of setting up defences on said horse tooth trough upper berth.
The thickness of said column is identical with the thickness of filled wall, and the length of said column is more than or equal to 100mm.
Advantage and good effect that the present invention has are: between filled wall side and agent structure, build the plain concrete column; Filled wall is connected with agent structure; Agent structure and column all adopt concrete material, have reduced the crack that the difference in shrinkage between the foreign material causes; Column and filled wall effectively are connected through horse tooth trough; Strengthen the snap-in force between the two foreign material bodies of wall greatly; The crack of having reduced effectively between column and the filled wall produces; In sum, the present invention builds the plain concrete column between filled wall side and agent structure, and column is connected with agent structure through same material; Be connected through horse tooth trough and filled wall, successfully solved between main body concrete structure and the filled wall because of the not enough crack problem that contraction causes with the body of wall foreign material of snap-in force between the body of wall; Simultaneously, column is the row's of adjusting brick size effectively, reduces the building block proportion of goods damageds; And simple to operate, compare with maintenance cost and social reputation, with low cost, can produce tangible economic benefit and social benefit.
Description of drawings
Fig. 1 is the structural representation that the present invention implements.
Among the figure: 1, agent structure, 2, column, 3, structural beams, 4, skew brick, 5, filled wall.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of job practices that prevents vertical cracking between agent structure and the filled wall:
1) after the construction of completion agent structure 1, before construction filled wall 5, between filled wall 5 sides and agent structure 1, reserves the column space;
2) construction of completion filled wall 5; During construction filled wall 5; It is built into horse tooth trough with side that agent structure 1 is connected; Filled wall 5 tops are connected with structural beams 3 through skew brick 4, and the tension rib that is provided with in the filled wall 5 should connect the column space of passing reservation and be connected with the agent structure 1 of its side;
3) install the column template at the place, column space that reserves, build the plain concrete vibration compacting and form column 2, filled wall 5 and agent structure 1 are linked into an integrated entity through column 2.
In order to ensure the anti-seismic performance of filled wall 5, the tension rib in the filled wall 5 still connects at the column position and passes, and must not break off.
The column template is reinforced with screw rod through walls, overlaps pvc pipe on the screw rod through walls, is convenient to form removal, reduces because of the damage of reinforcing template to filled wall.The concrete of building column 2 preferably uses the microdilatancy plain concrete, can further improve the effect that reduces cracking.
Above-mentioned column 2 should satisfy the operability of column concrete pouring construction as a kind of structural column, must not be less than 100mm.The length of column 2 can combine to arrange the brick size, and suitably adjustment is to reduce the building block proportion of goods damageds.The thickness of column 2 is identical with the thickness of filled wall 5.
Although combine accompanying drawing that the preferred embodiments of the present invention are described above; But the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
