[specific embodiment]

To shown in Figure 2, a kind of concrete slab roughness control of the present invention device comprises capable 1, two marker posts 2 of two carriages, a floating rule 3 like Fig. 1; Said each carriage capable 1 comprises a plurality of carriages 11; Said two carriages capable 1 laterally arrange, and capable 1 the spacing d of two carriages is less than the length of said floating rule 3, and said a plurality of carriages 11 all are fixed on the ground layer 4; Said two marker posts 2 place respectively on the carriage capable 1, and said floating rule 3 is cross-placed on two marker posts 2.

Said marker post 2 is fixed on the said carriage 11 through iron wire, prevents concreting, causes said marker post 2 displacements in the process of vibrating.Said marker post 2 is straight round steel pipe, and the diameter of this steel pipe is between 20mm to 25mm.Said floating rule 3 is the straight bar of rectangle.

As shown in Figure 3, said carriage 11 comprises that an angle bar 111 and vertical welding are connected to a reinforcing bar 112 at this drift angle place, angle bar 111 lower end, and the length of said angle bar 111 is between 15mm to 25mm, and the specification of said angle bar is ∠ 25 * 25 or ∠ 30 * 30; This carriage 11 is made simple, and said marker post 2 is had good support effect, makes marker post 2 be difficult for landing.Certain said carriage 11 also can be welded together to form the Bracket for steel bar of one " Y " shape through straight bar steel muscle and " V " shape reinforcing bar.

As shown in Figure 4; When said ground layer 4 is the plain concrete face or during the stone bedding plane; Below each said carriage 11, establish a pier base 5, through this pier base 5 said carriage 11 is fixed on the said ground layer 4, said pier base 5 can be cement mortar pier or concrete pier.

As shown in Figure 5, when said ground layer 4 was the template face of reinforced concrete floor, said carriage 11 was through being fixedly welded on the said ground layer 4 with beam reinforced steel bar 6.

More than be the structural relation of a kind of concrete slab roughness control of the utility model device, as shown in Figure 6, its concrete operations comprise the steps:

Step 1 ', on qualified ground layer or slab form, carry out the snap the line setting-out, arbitrarily the spacing between adjacent two Loft Lines is wipeed off to guarantee that floating rule 3 two ends can lean against on the said marker post 2 less than the length of said floating rule 3;

Step 2 ', on Loft Line, survey the high control point of bidding with level gauge, and draw absolute altitude control directrix.

Step 3 ', said carriage 11 is set at interval on Loft Line, the absolute altitude of said carriage 11 is by the decision of absolute altitude control directrix; When the concrete slab of laying is reinforced concrete floor, carriage 11 and beam reinforced steel bar 6 are welded; When the concrete slab of laying was plain concrete ground, the pier base 5 that adopts cement mortar pier or concrete pier to process was fixed in carriage 11 on the ground layer 4;

Step 4 ', on said carriage capable 1, place marker post 2, with iron wire that marker post 2 and carriage 11 colligations are firm, said marker post 2 end faces are concordant with concrete surface;

Step 5 ', the concrete system of mixing, transport, pave;

Step 6 ', utilize vibrator that the concrete pavement that paves is carried out vibration compacting;

Step 7 ', floating rule 3 is placed on the two adjacent marker posts 2, utilize 3 pairs of concrete surfaces of floating rule wipe off, rub with the hands the hair, compacting; If find uneven part, in time excavation and filling is mended flat in the strickling process;

Step 8 ', remove marker post 2, fill up with concrete and pull out the recessed joint that stays behind the marker post 2 and the compacting of clapping;

Step 9 ', the maintenance of concrete surface, often watering maintenance in concrete surface becomes to live 12 hours, curing time, be no less than 7 days.

The utility model is rationally arranged through marker post, carriage, floating rule, in the work progress of concrete slab, has controlled the planeness of concrete plate surface well.This apparatus structure is simple, uses easy to operately, and control accuracy is high.

The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented according to this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
