Description

A kind of plucking vacuum mat and construction technology
Technical field
The present invention relates to a kind of vacuum mat, and in particular to a kind of plucking vacuum mat.
Background technology
Cast-in-place concrete can improve every technical performance of concrete after vacuum operation.Arrive So far, the vacuum operation of horizontal surface concrete progressively popularization and application, such as highway division exist Soft sucking mat vacuum operation is successfully applied in casting concrete road surface, civil engineering department is in high level Also vacuum operation is applied during the floor of building is cast-in-place.However, vacuum operation is applied in airfield runway In work, but cannot promote because concrete track roughness requirements are higher (roughness be evaluation An important indicator of the airfield runway for high grade project).
In the prior art, airfield runway work progress is usually:Runway ground fills and leads up whole reality --- --- disturbing concrete is to full mould for disturbing concrete --- laying bar-mat reinforcement --- for formwork erection --- rolling --- troweling --- plucking --- maintenance --- indwelling temperature joint is evened up ---.
After plucking terminates, vacuum operation is carried out immediately such as, it will problems with occur:
(1) hair side of pull-out can during bedding suction pad, be damaged.
(2), during vacuum operation, suction pad is delivered to coagulation vacuum pressure (70-90KN/M2) On native face, compress concrete, hair side is destroyed.It can be seen that after plucking, vacuum operation is difficult to Carry out.
If first carrying out vacuum operation plucking again, because the concrete after vacuum operation has The initial strength of more than 0.12MPA, it is maximum up to more than 0.3-0.5MPA, so hard On concrete surface, plucking is relatively taken a lot of work.
Therefore, design one kind and can both pull out hair side simultaneously, the device of vacuum operation can be completed again Become technical problem urgently to be resolved hurrily.
The content of the invention
The technical problem to be solved in the present invention is the defect for overcoming prior art, there is provided a kind of plucking Vacuum mat, can both pull out hair side simultaneously, can complete vacuum operation again.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of plucking vacuum mat of the present invention, which includes vacuum soft sucking mat and is arranged at described true Plucking utensil below empty soft sucking mat, between the plucking utensil and the vacuum soft sucking mat Connected by fixed mount.
Further, the vacuum soft sucking mat includes the caulking gum for setting gradually from outside to inside Cloth, plastic deeping and filtration nylon cloth, are provided with suction nozzle on the caulking gum cloth.
Further, the plucking utensil is welded on the fixed mount.
Further, the fixed mount is steel framework, and the thickness of the steel framework is 2mm.
Further, the plucking utensil includes some steel discs, and some steel discs are longitudinally arranged On the steel framework, the distance of the two neighboring steel disc is 3mm.
Further, the surrounding of the steel framework is vertically welded with steel disc upwards, and the vacuum is flexible Suction pad is connected with the steel framework by the steel disc.
The invention also discloses a kind of technique constructed by use plucking vacuum mat, which includes Following steps:
(1) after pouring the concrete troweling smash, exactly by plucking vacuum mat pressure;
(2), in pressure after plucking vacuum mat, suction pad both sides are touched slightly with vibrating spear and is laterally stood Welding steel piece, after vibrating spear is touched, make steel bar peripheral recesses concrete liquefy and reach it is smooth, Ensure the air-tightness of suction pad surrounding;
(3) carry out plucking work.
The beneficial effect that reached of the present invention is:
The plucking utensil of the present invention is welded on square iron frame, and plucking utensil is attached to the flexible suction of vacuum Pad is following.After concrete troweling, plucking utensil is pressed in concrete, and starts vacuum pump, So that plucking, vacuum operation are once completed.The plucking suction pad of the present invention has certain flexibility, Vacuum pressure can be delivered on the steel framework below suction pad during vacuum operation, then both sides are passed to by which Punching block (or concrete) on, therefore, vacuum pressure is not transferred on concrete surface, from And ensure that the plucking of concrete surface is required, while having certain rigidity, it is ensured that the hair side of pull-out The depth is consistent, be evenly distributed.
Description of the drawings
Accompanying drawing is used for providing a further understanding of the present invention, and constitutes one of description Point, together with embodiments of the present invention for explaining the present invention, do not constitute the limit to the present invention System.In the accompanying drawings:
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the structural representation of plucking utensil;
Fig. 3 is the structural representation of vacuum soft sucking mat.
Specific embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that herein Described preferred embodiment is merely to illustrate and explains the present invention, is not used to limit this It is bright.
As shown in Figure 1 to Figure 3, a kind of plucking vacuum mat of the invention, which includes that vacuum is flexible Suction pad 1 and the plucking utensil 2 being arranged at below vacuum soft sucking mat 1, plucking utensil 2 with it is true Connected by steel framework 3 between empty soft sucking mat 1.
In the present embodiment, vacuum soft sucking mat 1 includes the sealing rubber for setting gradually from outside to inside Adhesive plaster 11, plastic deeping 12 and filtration nylon cloth 13, are provided with suction on caulking gum cloth 11 Mouth 4.Wherein, plastic deeping 12 is used to ensure that steam is unobstructed.
In the present embodiment, plucking utensil 2 is welded on steel framework 3, and the thickness of steel framework 3 is 2mm。
In the present embodiment, plucking utensil 2 includes some steel discs 5,5 longitudinal cloth of some steel discs It is placed on steel framework 3, the distance of two neighboring steel disc 5 is 3mm.
In the present embodiment, the surrounding of steel framework 3 is vertically welded with steel disc 5 upwards, and vacuum is flexible Suction pad is connected with steel framework 3 by steel disc 5.
The invention also discloses a kind of technique constructed by use plucking vacuum mat, which includes Following steps:
