Abstract
The utility model discloses a prevent structure of a secondary structure and two secondary structure handing -over department feather checkings, by being located for a secondary structure's shear force wall and infilled wall handing -over department for two secondary structure add the C20 who the establishes concrete transition zone of expanding a little, build by laying bricks or stones the infilled wall wall body both sides for two secondary structure keep somewhere indenting and pre -buried drawknot reinforcing bar constitution, wherein add the C20 that the establishes concrete transition zone of expanding a little, its appearance structural shapes is the indenting shape. The width design that C20 expanded the concrete transition zone a little is 200mm~300mm. Follow the high every 200mm of indenting ~500mm department and set up 2 phi, 6 horizontal drawknot reinforcing bars, imbed the length of the interior drawknot reinforcing bar of wall body, all should not be lighter than 1000mm from staying cha chu to count every limit. The utility model discloses the structure is safe practical, adds the C20 who the establishes concrete transition zone of expanding a little, for when carrying out local standard, provides the wall lacing wire transition region, gos deep into smoothly in the middle of the wall body mortar joint. Add and to establish C20 and expand the indenting form of concrete transition zone a little and reached the effect of constructional column, reduce, the crack of control wall body produces, the intensity of reinforcing brickwork.
Description
Technical field
This utility model is related to a kind of construction preventing primary structure and secondary structure junction generation crack, belongs to building
Field of engineering technology.
Background technology
Primary structure refers to body structure portion, is shear wall structure, is supporting member, first completes.Some subsequently carrying out
Nonweight-bearing masonry, constructional column, lintel etc. some need the part that completes to be commonly referred to as secondary structure (the two before decoration
structure).Why claim secondary structure, be because its operation time of carrying out be those supporting members construction finish with
Just construct afterwards.Secondary structure is for agent structure, is non bearing structure, and such as constructional column, collar tie beam, sealing are anti-
Beam, parapet, bear down on one, fill wall, partition wall etc..
The construction scope of commercial residential building was increasing in recent years, as the masonry of the major bearing structures form of residential building
Structure produced problem also increases therewith, and particularly wall body slit is modal problem.The generation of bond structure crack leads to body of wall
Seepage, have jeopardizes structure safety, from affect the attractive in appearance of building in appearance it is seen that prevention bond structure crack generation be a urgency
Problem to be solved is it is necessary to attract great attention.In prior art, prevention bond structure crack several method, but not ideal or
There is a weak point:
1. fiberglass mesh band, has typically added two-layer, and time crack can only say it is to postpone, and can not prevent.
2. add expanded metal lath in plastering, local still occurs, simply delay the time occurring.
3. smear polymers anti-cracking mortar, effect is all more better than above, but acceptable on a small quantity, and large area uses, and cost is too
High.
Tianjin town and country construction and Communications Commission's file [are built matter peace [2010) No. 1208] to require, from January 1st, 2011
Rise, new construction wall tie bar, constructional column reinforcing bar, the setting of beam steel should adopt reserved, pre-buried mode.And take once
In structure, the mode of reserved tension rib is very high to the positional accuracy requirement of wall lacing wire, and primary structure formwork also should not be constructed, pole
Problems with easily occurs:
1) primary structure formwork inconvenience, template loss is larger；
2) wall lacing wire position during main structure construction it is difficult to ensure that, the inaccurate situation in position, wall easily occur
Lacing wire position is not to it is impossible to be deep in the middle of filling wall mortar joint；
3), after wall plastering, primary structure (shear wall) and secondary structure (filling wall) junction easily produce crack.
How to solve primary structure (shear wall) present in above-mentioned prior art and secondary structure (filling wall) junction
Easily produce crack problem, become the problem of building industry engineers and technicians extremely concern, be also construction engineering technology
The problem of personnel's urgently R and D.
Utility model content
The purpose of this utility model, is the defect existing for prior art, and provides a kind of simple to operate, convenient peace
Entirely, practical a kind of construction preventing primary structure and secondary structure junction generation crack.
This utility model for achieving the above object, be the technical scheme is that
A kind of construction preventing primary structure and secondary structure junction generation crack it is characterised in that: described once tie
Structure and secondary structure are respectively shear wall and filling wall, the described structure preventing primary structure and secondary structure junction generation crack
Make, by be located at for primary structure shear wall with for secondary structure filling wall junction add c20 micro expansive concrete mistake
Cross band, build the indwelling horse tooth trough in the filling wall body of wall both sides for secondary structure and pre-buried steel tie composition by laying bricks or stones, wherein said
The c20 micro expansive concrete intermediate zone adding, its contour structures shape is in horse tooth trough shape.
Described c20 micro expansive concrete intermediate zone, its width design is 200mm～300mm, and described width design cannot be less than
200mm.
Described pre-buried steel tie, the horizontal steel tie of 2 φ 6 of setting along at the high every 200mm～500mm of horse tooth trough, often
While stretching into the length of steel tie in body of wall, all it is not preferably less than 1000mm from staying Cha Chu to count every side.
Beneficial effect
1st, add c20 micro expansive concrete intermediate zone, be in execution local meam time, provide wall lacing wire one transitional region,
Smoothly go deep in the middle of body of wall mortar joint.
2nd, the horse tooth trough form adding c20 micro expansive concrete intermediate zone has reached the effect of constructional column, reduces, controls body of wall
Crack produce, strengthen masonry intensity.
Brief description
Fig. 1 is organigram of the present utility model.
In Fig. 1: 1 is secondary structure；2 is c20 micro expansive concrete intermediate zone；3 is primary structure；4 is steel tie.
Specific embodiment
A kind of construction preventing primary structure and secondary structure junction generation crack, as shown in figure 1, described primary structure
3 and secondary structure 1 be respectively shear wall and filling wall, the described structure preventing primary structure and secondary structure junction generation crack
Make, by be located at for primary structure 3 shear wall with for secondary structure 1 filling wall junction add c20 micro expansive concrete
Intermediate zone 2, builds the indwelling horse tooth trough in the filling wall body of wall both sides for secondary structure 1 by laying bricks or stones and pre-buried steel tie 4 forms, wherein
The described c20 micro expansive concrete intermediate zone 2 adding, its contour structures shape is in horse tooth trough shape.
Described c20 micro expansive concrete intermediate zone 2, its width design is 200mm～300mm, and described width design must not be little
In 200mm, the width design of this utility model intermediate zone 2 is 200mm.
