Abstract
The invention provides a method for reinforcing a brickwork wall by sticking a bamboo mat. According to the method for reinforcing the brickwork wall by sticking the bamboo mat, not only the construction speed is high and an influence range is small, but also the bearing force and deformation of the brickwork wall are enabled to meet subsequent use requirements. Bamboo materials are renewable natural fast-growing materials, so that by utilizing the bamboo mat to reinforce the existing buildings, consumption of resource and energy source can be effectively reduced, and sustainability of the existing building reconstruction industry is improved.
Description
Technical field
The present invention relates to building engineering field, the most just relate to a kind of side pasting bamboo mat Strengthened Masonry Walls wall
Method, for the reinforcement and repair of existing building.
Background technology
Masonry structure building has obtained popularization and application on a large scale in building trade.After using for many years, masonry
Generally there is a certain degree of aging or damage in structure, and makes it use owing to part building uses function to adjust
Load increases, and safety stock is decreased obviously, and need to improve its bearing capacity by rational reinforcement means, it is ensured that peace
Full use.
Chinese patent ZL201210282611.0 discloses a kind of method of steel structure reinforcing masonry wall,
It comprises the following steps: 1) hole respectively at collar tie beam two ends, is respectively adopted high-strength bolt to wearing, by common brick wall
Two pieces of strengthening steel slabs of both sides are reliably connected with the collar tie beam of upper end；2) being respectively adopted chemical bolt in two bottom sides will
Connector is connected with constructional column；3) lower end of strengthening steel slab is connected to by high-strength bolt the edge of a wing of connector
Place, back side strengthening steel slab method of attachment is identical with this；4) hole on Strengthened Masonry Walls wall, insert reinforced bar fastener,
Bend and weld the back-shaped button of formation, the steel plate of fastening both sides；5) element cement or other covering are smeared at surface of wall
After thing, i.e. complete the reinforcing to body of wall.Enhance the deformability of body of wall, extend body of wall broken by ftractureing
The bad time, the energy dissipation capacity of body of wall is significantly enhanced.But this is consolidated structure and utilizes steel structure reinforcing cost
Too high, the most easily masonry wall is produced and destroy.
Summary of the invention
It is an object of the invention to need to destroy existing block for the above-mentioned existing ruggedized construction of masonry wall without constructional column
The technological deficiency of body wall construction, it is provided that a kind of method pasting bamboo mat Strengthened Masonry Walls wall, takes to paste bamboo mat and adds
Gu masonry wall not only speed of application is fast, coverage is little, and can guarantee that the bearing capacity of masonry wall meets
Follow-up use requirement.Bamboo wood is renewable natural fast-growing material, and using bamboo mat to reinforce existing building can effectively subtract
Few consumption to energy resource, improves the sustainability of reconstruction of existing building industry.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of method pasting bamboo mat Strengthened Masonry Walls wall of present invention design,
It is characterized in that, it comprises the following steps:
(1) bamboo mat region need to be pasted in masonry wall surface and carry out surface process；
(2) bamboo mat region need to be pasted at dry surface of wall and smear primer, treat that primer air-dries；
(3) at one full coat structure glue of bamboo mat, cement and the coordination compound of medium sand, and bamboo mat is pasted masonry wall
Surface；
(4) bamboo mat after pasting is applied mechanical anchor；
(5) bamboo mat and block wall is made to combine closely not less than 24 hours.
Further, when bamboo mat is pasted masonry wall surface by described step (3), bamboo mat centrage and body of wall pair
Linea angulata overlaps.
Further, the bamboo mat width in described step (3) is 200～500mm, pastes for monolayer, and bamboo mat is adopted
With width be 10mm～40mm, thickness < 1mm bamboo chip braiding form.
Further, the mechanical anchor described in described step (4) is completed with anchor bolt by steel plate.
Further, masonry wall need to be pasted bamboo mat region by described step (1) carry out the step of surface process and include:
First bamboo mat region surface of wall is pasted in polishing, until smooth, then hole in advance in anchor bolt position,
Aperture ratio anchor bolt diameter big 1～3mm, the degree of depth 30～50mm, finally remove the floating dust of block wall.
Further, making bamboo mat and the block wall time of combining closely in described step (5) is 24～120 hours.
Beneficial effect
The method pasting bamboo mat Strengthened Masonry Walls wall that the present invention provides, not only speed of application is fast, coverage is little,
And can guarantee that the bearing capacity of masonry wall meets follow-up use requirement；Masonry wall after reinforcing, its carrying
Force rate improves more than 30% before reinforcing.And using bamboo mat as reinforcement material, bamboo wood is renewable natural speed
Green material, uses bamboo mat to reinforce existing building and is effectively reduced the consumption to energy resource, improve existing building
The sustainability of transformation industry.
Accompanying drawing explanation
Accompanying drawing 1 is the floor map of the present invention.
Accompanying drawing 2 is the sectional view in A-A direction in accompanying drawing 1.
Detailed description of the invention
The best embodiment, the present invention will be further described.
Embodiment
As shown in figure 1 and 2, a kind of method pasting bamboo mat Strengthened Masonry Walls wall, it comprises the following steps:
The first step, without constructional column masonry wall 1, the load first born masonry wall 1 unloads, then to block
Body wall 1 is pasted bamboo mat region and is carried out surface process: use abrasive machine polishing to paste bamboo mat region surface of wall,
Until it is smooth；Hole in advance in anchor bolt position, diameter 10mm, degree of depth 40mm；Then masonry is removed
The floating dust of metope, the most stand-by；
Second step, breaks last layer primer in dry masonry wall 1 pastes bamboo mat region uniform, fullly,
Treat that primer air-dries；
3rd step, is the coordination compound of 1:1:1 in 2 one full coat structure glue of bamboo mat, cement and medium sand proportioning,
And bamboo mat is pasted the diagonal of masonry wall 1；Coordination compound solidification i.e. forms glue-line 4, such as Fig. 1 and Tu
Shown in 2；
4th step, applies mechanical anchor to the bamboo mat after pasting, and mechanical anchoring device 3 by one ruler cun is
The steel plate of 350mm × 30mm × 10mm and two setscrews composition, steel plate two ends be respectively arranged with one a diameter of
The hole of 10mm, pitch-row 310mm, anchor screw selects M8；
5th step, compresses bamboo mat 2 with masonry wall 1, makes bamboo mat 2 combine closely with masonry wall 1, the time
