In aforementioned shear-wall strengthening constructing structure, the split bolt is equidistantly uniformly distributed setting on shear wall.
To pull-type steel plate shear force wall strengthening construction, the specific method is as follows:
Former shear wall surface rendering layer and weaker zone are cut first, until being completely exposed solid base, for table
The biggish column surface of face convex-concave, convex surface are tied with hand hammer, and recess is smoothed out with cement mortar, and corner grinds fillet, and uses wire brush
Surface dust is brushed away with hair dryer and is blown off；It is polished with angle grinder and removes corrosion and the dirt of surface of steel plate, expose metallic luster,
It is clean with cotton yarn erasing before pasting；It is positioned by Design of Reinforcement position unwrapping wire, is accurately marked in concrete surface and paste position wheel
Profile and batten plate position；Steel part is first fabricated to the dimensions of design requirement, and steel plate and shear wall are positioned
Then drilling pours into modified epoxyn in reserved grout hole, and uses split bolt by steel plate and shear wall
Reinforce connection, guarantees that there is good bonding between the steel plate of outsourcing and shear wall faying face, make the new and old two parts of ruggedized construction
It can cooperation.
Compared with prior art, the four story shear walls reinforcing that the present invention uses is surface-treated, and shear-wall strengthening only needs
It is reinforced at four layers, does not need to reinforce always from basis to 4 layers, significantly reduce construction period and reduce residential usage face
Product, and do not interfere with other floors；Shear-wall strengthening is positioned by Design of Reinforcement position unwrapping wire, is accurately marked in concrete surface
Paste position contour line and batten plate position；Steel plate and shear wall are subjected to positioning drilling, guarantee that structural strengthening load is uniform；
Covered with Angles grouting liquid guarantees its excellent cementability using modified epoxyn；Steel will be reinforced using split bolt
Part and shear wall are reinforced connecting, and guarantee there is good bonding between encased steel plate and component faying face, keep ruggedized construction new and old
Two parts energy cooperation；Structural stability is good, long service life, and the Design of Reinforcement subsequent service life meets structure 50
Year time limit requirement；Covered with Angles steel piece surface carries out anti-corrosion fire prevention processing, polishes steel piece surface, removes the rust of steel piece surface
Erosion, dirt etc. make steel piece surface without attachments such as visible grease, dirt, oxide skin, iron rust, then brush antirust on surface
Paint is not less than the protective layers such as 25mm solid cement mortar, mineral wool mortar, and structure fire safety is effectively ensured.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention will be made below further detailed
Explanation.
Embodiment:
Referring to attached drawing 1, the present embodiment provides one kind to pull-type steel plate shear force wall strengthening construction structure, the appearance of shear wall 1
Face is laid with one layer of steel plate 2, and steel plate 2 uses Q345 steel, sealing welding between steel plate 2, and coats between steel plate 2 and shear wall 1
There is modified epoxyn 5, be equidistantly uniformly distributed on shear wall 1 and be provided with split bolt 4, split bolt 4 is M12
Split bolt, split bolt 4 run through wall and steel plate 2, and the steel plate 2 of 1 opposite sides of shear wall along the width direction of shear wall 1
It is strained and fixed by split bolt 4, the outside of steel plate 2 is welded with batten plate 3, and batten plate 3 is transversely arranged, and 3 edge of batten plate
The short transverse of shear wall 1 is distributed.
To pull-type steel plate shear force wall strengthening construction, the specific method is as follows:
Former 1 surface rendering layer of shear wall and weaker zone are cut first, until being completely exposed solid base, for table
The biggish column surface of face convex-concave, convex surface are tied with hand hammer, and recess is smoothed out with high-grade cement mortar, and corner grinds fillet, is used in combination
Wire brush and hair dryer, which brush away surface dust, to be blown off；It is polished with angle grinder and removes corrosion and the dirt on 2 surface of steel plate, expose gold
