Description
Technical field
The present invention relates to a kind of fire hydrant box back side body of wall and construction method thereof, belong to technical field of building construction.
Background technology
nullAccording to design and code requirement，All different materials for wall junctions and body of wall are embedded with equipment box、When cabinet equivalent body of wall is wide，Layer of steel wire net is overlayed in junction and box back surface before painting，By conventional construction method，Putting on full scale steel wire net is used at the fire hydrant box back side，Periphery stretches out casing 150mm，Layering is plastered，Employing putting on full scale steel wire net can be by the material of varying strength with connecting together，Structure is integral，Make expansion and contraction uniform，Decrease the drawing crack of wall face，As the patent No. 201320198063.3 provides a kind of wall internal corner insulation construction，Base course wall and exterior wall intersect composition wall internal corner，Screed it is provided with on wall face，Layer of steel wire net it is equipped with outside screed，Steel wire is extended to base course wall by exterior wall and covers whole wall internal corner，And use expansion bolt to be anchored on base course wall and exterior wall by steel wire，This patent has the advantages that body of wall is the most easy to crack.
But it is also required to certain operative skill when floated coat is carried additionally steel wire construction, complex steps, typically requiring attention problems with: the mesh plaster of (1) metope should accomplish that selection is reasonable, linked network is smooth, nail net is firm, it is closely knit to plaster, and can carry out after hidden item inspection is qualified.(2) matrix should be cleared up before linked network, repair levelling metope, and keep certain humidity.(3) linked network should flatten, and can fix with nailing or with built-in fitting with beam, post or wall connecting, should ensure that the indeformable arch camber of steel mesh；(4) web material overlap joint should be smooth, continuous, firm, and the lap of splice is not preferably less than 100mm；(5) in linked network must be placed in coat of plaster, web material is preferably greater than 5mm with the spacing of matrix, but must not expose, and should prevent web material and fixture from getting rusty and corroding；(6) coat of plaster must be firmly bonded with matrix, and matrix surface should use polymer water mud bottoming, plasters and should divide all over compacting.Additionally, steel wire by brick wall can use iron nail to fix in hammering into brick wall mortar joint, but by concrete walls, beam, cylinder steel wire is but high due to concrete strength, can not directly use and hammer into iron nail and fix, general employing hammers into iron nail again after concrete surface is holed and is fixed, in sum, obviously putting on full scale steel wire net labour intensity is big, when not only having taken a lot of work but also be awkward, and when the density of steel wire Yu the point of metope colligation is inadequate, the most easily produce rendering layer hollowing, cracking, the phenomenons such as peeling, the steel wire currently used is sandwiched between metope and mortar, hole is there is on steel wire, mortar thickness in Steel Wire Surface and mesh is the most inconsistent, particularly when mortar is thicker, the fastness of the screed spread is the most worse, often occur that mortar stream falls, the situation such as drop；Even if completing float work, after Practical Completion, due to expanding with heat and contract with cold or slight deformation, External Force Acting etc. of steel wire, box back surface coat of plaster cracking in various degree all can be caused, come off under serious conditions, cavity, had a strong impact on the normal of building and used and aesthetic.
Therefore, metope putting on full scale steel wire net still can't resolve the problem painting crack, and steel wire can only be surface action to cracking of wall surface, and metope to be truly realized does not ftractures, and is also intended to from matrix, it is simply that masonry project is started with.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of fire hydrant box back side body of wall and construction method thereof, the steadiness that can make fire hydrant box back side body of wall is more preferable, can avoid using putting on full scale steel wire net, operation is simple, solves fire hydrant box back side body of wall and produces the problem painting crack.
In order to achieve the above object, the present invention adopts the following technical scheme that a kind of fire hydrant box back side body of wall, brick wall body of wall has reserving hole for embedding fire hydrant box, in reserving hole, the body of wall position corresponding to the fire hydrant box back side builds multiple concrete slab placed up and down by laying bricks or stones, and use Bar Anchorage prefabricated in concrete slab in brick wall body of wall, topmost concrete slab is built with crossing beam slab top, foot concrete slab exceeds fire hydrant casing bottom, the two ends, left and right of described concrete slab are all beyond the fire hydrant casing left and right sides, stagger in the transverse slot between transverse slot and brick wall between described concrete slab, described concrete slab is left, the vertical gap of right part is left with fire hydrant box, stagger in vertical gap between right flank and body of wall.
