Abstract
The utility model discloses a cement mortar surface layer reinforcing mesh for reinforcing a brick-concrete structural wall. The cement mortar surface layer reinforcing mesh comprises a reinforcing mesh; reinforcing ribs are arranged in the transverse and vertical directions of the reinforcing mesh every 300mm; the intersection of the reinforcing ribs is provided with an anchor bar; the anchor bar is reliably drawn close to the wall; after the anchor bar is fixed, the cement mortar is smeared on the wall layer by layer, so that the cement mortar surface layers are reliably adhered to the wall. With the adoption of the cement mortar surface layer reinforcing mesh, the thickness of the cement mortar surface layer can be reduced; the construction progress is accelerated; and the quality of the reinforcing project is ensured.
Description
Technical field
The utility model relates to civil engineering structure reinforcing technique field, is specifically related to a kind of cement screedn steel mesh reinforcement that is used to reinforce the brick mix structure body of wall.
Background technology
Wenchuan 5.12 after the earthquake, in order to reduce the loss that earthquake brings, house and town and country construction cloth promulgated by the ministries or commissions of the Central Government " Standard for earthquakeresistant evaluation of buildings " (GB50423-2009); Requirement according to this standard; Will carry out strengthening reconstruction for the brick mix structure body of wall that does not satisfy shockproof requirements, its traditional method is on the basis of original body of wall, to increase cement screedn, is provided with in it in length and breadth to reinforcing bar; Reinforcing bar takes the mode of colligation to be fixed on the body of wall; In order to ensure the quality of reinforcing wall, shorten the construction period, develop some new reinforcing steel bar net cement screedns and be very important.
Summary of the invention
The purpose of the utility model is, a kind of mesh reinforced cement mortar surface layer that is used to reinforce the brick mix structure body of wall is provided.
In order to realize above-mentioned task, the utility model is taked following technical solution:
A kind of cement screedn steel mesh reinforcement that is used to reinforce the brick mix structure body of wall comprises steel mesh reinforcement, and the vertical muscle of steel mesh reinforcement and horizontal bar are in same plane; Horizontal and vertical at steel mesh reinforcement whenever is provided with reinforcing rib at a distance from 300mm, and there is dowel in the intersection of reinforcing rib; With the reliable drawknot of body of wall; Behind the drawknot, smear cement mortar, cement screedn and body of wall are sticked together reliably at the body of wall higher slice.
Adopt the cement screedn steel mesh reinforcement that is used to reinforce the brick mix structure body of wall of the utility model, can reduce the thickness of cement screedn, accelerated construction speed, guaranteed the quality of stabilization works.
Description of drawings
Fig. 1 is the cement screedn steel mesh reinforcement sketch map that is used to reinforce the brick mix structure body of wall of the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
The specific embodiment
Referring to Fig. 1, the cement screedn steel mesh reinforcement that is used to reinforce the brick mix structure body of wall of the utility model comprises steel mesh reinforcement 1; Horizontal and vertical at steel mesh reinforcement 1; Every separated 300mm place is provided with reinforcing rib 2, and there is dowel 3 in the intersection of reinforcing rib 2, after steel mesh reinforcement is fixing; Cement mortar is smeared in layering, and cement screedn and body of wall are sticked together reliably.
During use, carry out according to the following step:
(1) preparation of construction: set up the operation support body in the body of wall both sides, lay scaffold floor, operation support body and the reliable drawknot of body of wall are to guarantee construction safety.Construction machineries such as hoist engine are installed, to guarantee the transportation of material.
(2) root out the building rendering layer of former metope, according to designing requirement, in order to reduce the damage to original structure as far as possible, former rendering layer is rooted out in the mode layering of adopting static(al) to remove.
(3) metope cleans: remove the floating ash on loam brick and the mortar joint with wire brush, thoroughly blow away floating ash with blast fan again, the water with band pressure washes away body of wall then.
(4) repair body of wall: the metope that destroys when alkali is lost serious metope and roots out, should remove loose part earlier also with 1: 3 cement sand plaster, with loosening jointing mortar rejecting; Water washes away former metope again.
(5) body of wall perforate: according to the dowel position and the quantity of mortar surfacing steel bar net, mark out dowel 3 positions at body of wall, the aperture is 20mm; Because the rigidity of steel mesh reinforcement 1 is bigger, for steel mesh reinforcement 1 reliably is connected with body of wall, is convenient to plaster; The spacing of reinforcing rib 2 is 300mm; Bore dowel 3 holes with Churn drill at body of wall, bit diameter should be than about the big 5mm of dowel 3 diameters, and drill bit is selected the alloy tool steel bit of φ 25 for use.Hole depth is 240mm/370mm, makes dowel 3 imbed body of wall fully, and during boring, drill bit keeps vertical with metope all the time.
(6) hole flushing: be to plant a most important link in the dowel 3, because inside, the intact back of hole drill has a lot of ashes, lime-ash, directly the quality of dowel 3 is planted in influence, so must clean out foreign material in the hole.The hole flushing method is: with the commercially available hairbrush of gaining sharp brand happily (this hairbrush does not fall hair), put elongated bar, extend at the bottom of the hole, twitch repeatedly back and forth, take dust, disintegrating slag out of, use compressed air again, blow out floating dust in the hole.Be stained with alcohol or acetone scouring hole inwall with absorbent cotton again after having blown.But can not use scrub water, volatile because of alcohol and acetone, water is not volatile.With can be very in the scrub water metapore fast dry.
(7) injecting glue is planted dowel: behind the inner drying of hole, adopt the bar planting glue of commercially available Ai Laoda brand that dowel 3 is fixing.
(8) the cement screedn steel mesh reinforcement of the reinforcing brick mix structure body of wall of laying the utility model; According to the position and the size of reinforcing wall, earlier mortar surfacing steel bar net is processed into suitable shape, mortar surfacing steel bar net is transported to desired location; Be fixed on the metope with dowel 3 again; When laying mortar surfacing steel bar net, vertical strengthening ribs 2 should lean on metope and prop with steel bar end, guarantees that mortar surfacing steel bar net and body of wall are connected firmly.
(9) the brush interfacial agents is plastered: water the water-wet metope, when smearing cement mortar; In metope brush interfacial agents together, layering is plastered again, and every layer of depth of plastering is 10mm; Because the construction quality of original wall body is relatively poor; Perpendicularity deviation is big, and for the verticality of the body of wall after guaranteeing to reinforce, plaster and reach 10mm in the thickness.
(10) surface layer water seasoning prevents that sunlight is exposed to the sun, and carries out finished product protection.
(11) rubbish outward transport: with the rubbish that produces in rubbish of rooting out and the work progress; Use artificial according in a huddle as unit with the room; Be contained in again in the bag of cement it to be walked, treat that all rubbish are transported to a time-out, transport the building site with forklift and cram packer with rubbish with artificial.
Claims (1)
1. a cement screedn steel mesh reinforcement that is used to reinforce the brick mix structure body of wall comprises steel mesh reinforcement (1), it is characterized in that, horizontal and vertical at steel mesh reinforcement (1) whenever is provided with reinforcing rib (2) at a distance from the 300mm place, and there is dowel (3) in the intersection of reinforcing rib (2).
