Abstract
The invention provides a method for smearing a high-ductility cement-based composite material to reinforce a masonry wall without constructional columns. The construction speed is high, the influence range is small, and it can be guaranteed that the bearing capacity and deformation of the masonry wall meet the following use requirements. The bearing capacity of the reinforced masonry wall is improved by over 40% compared with that of the masonry wall before reinforcement. Meanwhile, the high-ductility cement-based composite material is adopted to be smeared on the masonry wall for reinforcing the masonry wall, the use amount of reinforcing materials can be effectively reduced, and the consumption of resources and energy by an existing building reinforcement and reconstruction industry is reduced.
Description
Technical field
The present invention relates to building engineering field, the most just relate to one and smear high ductility cement
Based composites reinforces the method without constructional column masonry wall, for the reinforcement and repair of existing building.
Background technology
Masonry structure building has obtained popularization and application on a large scale in China.After using for many years,
Generally there is a certain degree of aging or damage in masonry structure, and owing to part building uses function
Adjustment makes its working load increase, and safety stock is decreased obviously, need to be by rational reinforcement means
Improve its bearing capacity, it is ensured that safe handling.
Chinese patent ZL201210282611.0 discloses a kind of steel structure reinforcing masonry
The method of wall, it comprises the following steps: 1) holes respectively at collar tie beam two ends, is respectively adopted high-strength
Two pieces of strengthening steel slabs of common brick wall both sides, to wearing, are reliably connected by bolt with the collar tie beam of upper end；
2) it is respectively adopted chemical bolt in two bottom sides to be connected with constructional column by connector；3) steel will be reinforced
The lower end of plate is connected at the edge of a wing of connector by high-strength bolt, back side strengthening steel slab connection side
Method is identical with this；4) hole on Strengthened Masonry Walls wall, insert reinforced bar fastener, bend and weld shape
Become back-shaped button, the steel plate of fastening both sides；5) element cement or other overcover are smeared at surface of wall
After, i.e. complete the reinforcing to body of wall.Enhance the deformability of body of wall, extend body of wall by opening
Splitting the time destroyed, the energy dissipation capacity of body of wall is significantly enhanced.But this is consolidated structure and utilizes
Steel structure reinforcing high cost, the most easily produces masonry wall and destroys.
Summary of the invention
It is an object of the invention to need to break for the above-mentioned existing ruggedized construction of masonry wall without constructional column
The technological deficiency of bad existing masonry wall structure, it is provided that one smears high ductility cement-base composite material
Reinforce the method without constructional column masonry wall, (right according to the sheared destruction pattern without constructional column masonry wall
Angle failure by shear), by masonry wall both sides of the edge and diagonally opposed to smear high ductility cement based multiple
Condensation material improves its bearing capacity.
Technical scheme
In order to realize above-mentioned technical purpose, what the present invention designed smears high ductility cement-base composite material
Reinforcing the method without constructional column masonry wall, it comprises the following steps:
(1) floating dust on masonry wall surface is removed；
(2) along need to smear high ductility cement-base composite material edges of regions nail on width be about 10～
20mm, thickness is equal to the batten of the thickness smearing high ductility cement-base composite material, by this district
Territory surrounds；
(3) surface of wall smear high ductility cement-base composite material region the fullest stamp
One layer of primer；
(4) when primer is unseasoned, high ductility cement-base composite material is spread upon what batten surrounded
Region is the most floating, and it is 200～500mm that high ductility cement-base composite material smears width, thickness
Being 10～20mm, the diagonally opposed ECC centrage smeared overlaps with body of wall diagonal；
(5) batten, water seasoning 28 days are removed
Beneficial effect
The present invention provides the side smearing the reinforcing of high ductility cement-base composite material without constructional column masonry wall
Method not only speed of application is fast, coverage is little, and can guarantee that the bearing capacity of masonry wall is full
The follow-up use requirement of foot；Masonry wall after reinforcing, its bearing capacity ratio improves more than 40% before reinforcing.
Use simultaneously and smear high ductility cement-base composite material Strengthened Masonry Walls wall, can effectively save reinforcing material
Material consumption, reduces the consumption to energy resource of the existing building strengthening reconstruction industry.
Accompanying drawing explanation
Accompanying drawing 1 is embodiment of the present invention floor map.
Accompanying drawing 2 is the sectional view in A-A direction in accompanying drawing.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the present invention will be further described.
Embodiment
As shown in figure 1 and 2, one is smeared high ductility cement-base composite material and is reinforced nothing structure
The method of post masonry wall, it comprises the following steps:
The first step, removes the floating dust on masonry wall 1 surface；
Second step, nails on width about along smearing high ductility cement-base composite material edges of regions
10mm, the batten of thickness 15mm, this region is surrounded；
3rd step, smears high ductility cement-base composite material region at surface of wall uniform, full
Last layer primer is broken on ground；
4th step, when primer is unseasoned, spreads upon batten by high ductility cement-base composite material
The region that surrounds is the most floating, and vertical and diagonally opposed high ductility cement-base composite material width is equal
For 300mm, thickness is 15mm, in the diagonally opposed high ductility cement-base composite material smeared
Heart line overlaps with body of wall diagonal；
5th step, removes batten, water seasoning 28 days.
The present invention provides the side smearing the reinforcing of high ductility cement-base composite material without constructional column masonry wall
Method not only speed of application is fast, coverage is little, and can guarantee that the bearing capacity of masonry wall is full
The follow-up use requirement of foot；Masonry wall after reinforcing, its bearing capacity ratio improves more than 40% before reinforcing.
Use simultaneously and smear high ductility cement-base composite material Strengthened Masonry Walls wall, can effectively save reinforcing material
Material consumption, reduces the consumption to energy resource of the existing building strengthening reconstruction industry.
