Abstract
The invention relates to a method for reinforcing a masonry wall without structural columns by sticking an environmentally-friendly textile fabric. Through the adoption of the method for reinforcing the masonry wall without structural columns by sticking the environmentally-friendly textile fabric, the construction speed is high, the influence scope is small, and besides, the situation that the bearing capacity and the deformation of the masonry wall can meet subsequent operating requirements can be guaranteed. The environmentally-friendly textile fabric is used for reinforcing existing buildings, so that waste clothings can be effectively utilized, the consumption of resources and energy resources can be reduced, and the sustainability of the conventional building reforming industry is improved.
Description
Technical field
The present invention relates to building engineering field, the most just relate to one and paste environmental protection weaving cloth reinforcing nothing
The method of 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 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
Two pieces of strengthening steel slabs of wall both sides are reliably connected with the collar tie beam of upper end；2) it is respectively adopted chemistry in two bottom sides
Connector is connected by bolt with constructional column；3) lower end of strengthening steel slab is connected to connector by high-strength bolt
The edge of a wing at, back side strengthening steel slab method of attachment is identical with this；4) hole on Strengthened Masonry Walls wall, insert steel
Muscle buckle, bends and welds the back-shaped button of formation, the steel plate of fastening both sides；5) element cement is smeared at surface of wall
Or after other overcover, i.e. complete the reinforcing to body of wall.Enhance the deformability of body of wall, extend body of wall
By cracking to the time destroyed, the energy dissipation capacity of body of wall is significantly enhanced.But this is consolidated structure and utilizes steel to tie
Structure reinforcement cost is too high, the most easily produces masonry wall and destroys.
Summary of the invention
It is an object of the invention to need to destroy for the above-mentioned existing ruggedized construction of masonry wall without constructional column existing
The technological deficiency of masonry wall structure, it is provided that the side without constructional column masonry wall reinforced by a kind of environmental protection weaving cloth of pasting
Method, takes to paste environmental protection weaving cloth and reinforces without constructional column masonry wall, and 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.Environmental protection weaving cloth is used to reinforce existing
Building can effectively utilize waste and old medicated clothing, reduces the consumption to energy resource, and that improves reconstruction of existing building industry can
Persistence.
Technical scheme
In order to realize above-mentioned technical purpose, the one of present invention design is reinforced without structure with pasting environmental protection weaving cloth
The method of post masonry wall, it is characterised in that it comprises the following steps:
(1) masonry wall surface need to be pasted environmental protection weaving cloth region and carry out surface process；
(2) paste environmental protection weaving cloth region at dry surface of wall and smear primer, treat that primer air-dries；
(3) in environmental protection weaving one full coat structure glue of cloth, and cloth of environmental protection being weaved pastes masonry wall surface；
(4) environmental protection weaving cloth is made to combine closely not less than 24 hours with block wall.
Generally 24～120 hours.
Further, cloth of environmental protection being weaved in described step (3) pastes the step on masonry wall surface and includes:
A () is first at masonry wall diagonally opposed stickup environmental protection weaving cloth, environmental protection weaving cloth centrage and masonry wall wall
Body diagonal overlaps；
B () secondly vertically pastes environmental protection weaving cloth at masonry wall body of wall edge；
The overlapping regions of c environmental protection weaving cloth that () pastes in step (a) and step (b) pastes environmental protection weaving cloth
Press strip.
Further, the environmental protection weaving cloth in described step (3) is 200～500mm width, whole environmental protection weaving cloth
Upper without obvious broken hole.
Further, in described step (c), the overlapping regions of environmental protection weaving cloth is 100～300mm, at overlap
Environmental protection weaving cloth press strip, press strip wide 100～250mm are pasted in territory, paste for monolayer.
Further, masonry wall surface need to be pasted environmental protection weaving cloth region by described step (1) and carry out surface
The step of reason is that first polishing stickup environmental protection weaving cloth region surface of wall, until smooth, then removes masonry wall
The floating dust in face.
Beneficial effect
The method without constructional column masonry wall reinforced by a kind of stickup environmental protection weaving cloth that the present invention provides, and takes to glue
Patch environmental protection weaving cloth is reinforced without constructional column masonry wall, and 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.Use environmental protection weaving cloth to reinforce existing building can have
Effect utilizes waste and old medicated clothing, reduces the consumption to energy resource, improves the sustainability of reconstruction of existing building industry.
Accompanying drawing explanation
Accompanying drawing 1 is the floor map of the embodiment of the present invention.
Accompanying drawing 2 is the structural representation in A-A direction in accompanying drawing 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the present invention will be further described.
Embodiment
The first step, the load bearing masonry wall 1 unloads, and then masonry wall 1 is pasted environmental protection weaving
Cloth region carries out surface process: use abrasive machine polishing to paste environmental protection weaving cloth region surface of wall, until flat
Whole, then remove the floating dust of block wall, the most stand-by；
Second step, beats last layer in dry masonry wall 1 pastes environmental protection weaving cloth region uniform, fullly
Primer, treats that primer air-dries；
3rd step, in a full coat structure glue of environmental protection weaving cloth 2, and by the environmental protection weaving cloth of wide 300mm
Paste on masonry wall 1, first paste diagonally opposed environmental protection weaving cloth, its centrage and body of wall diagonal
Overlap；Secondly the vertical environmental protection in masonry wall edge weaving cloth, its line-spacing body of wall edge, center 150mm are pasted；Two
The lap of splice of bar environmental protection weaving cloth is about 200mm, pastes environmental protection weaving cloth press strip, press strip in overlapping regions
Wide 150mm；Structure glue solidification i.e. forms glue-line 3, as depicted in figs. 1 and 2；
4th step, cloth 2 of environmental protection being weaved compresses with masonry wall 1, makes environmental protection weaving cloth 2 tight with masonry wall 1
Close combination, the time is 24 hours, makes structural adhesive layer harden to the specified intensity that current specifications specifies, pastes
The masonry wall that environmental protection weaving cloth is reinforced can continue carrying.
Above-mentioned environmental protection weaving cloth can be that the similar materials such as denim or major rupture strain fiber cloth replaces, whole
