In addition, concrete poured in the diagonal steel template is comprehensively leveled by the lengthened leveling ruler, and pouring errors on the surface of the concrete can be rapidly eliminated.
In a specific embodiment of the present disclosure, the height-adjustable bolt assembly may include a bolt body configured as a threaded rod, and a first nut, a first gasket, a second gasket, and a second nut sequentially sleeved on the bolt body. Step S11 may include the steps of:
s111: popping up a positioning line for positioning the inner surface of the angle steel on the ground; the inner surface of the angle steel is a surface for contacting concrete on the inner side of the angle steel formwork.
S112: aligning the inner surface of the angle steel with the positioning line;
s113: drilling bolt holes on the ground and the angle steel; and
s114: place first nut and gasket in the downside of angle steel, put the upside at the angle steel with second nut and second gasket for the bolt main part passes the bolt hole of second nut, second gasket, angle steel, the bolt hole on first gasket, first nut and ground, and wherein, the upper end of bolt main part is no longer than the upper surface of angle steel, and first nut is as adjusting nut, and the second nut is as lock nut.
Through steps S111 to S114, the angle iron can be positioned on the ground by the bolt assembly. Wherein the ground may be a concrete pad laid in advance.
In order to make the connection between the angle steel and the ground reliable and stable, step S113 may include drilling a plurality of bolt holes at intervals along the extending direction of the angle steel, so that each angle steel is positioned with the ground through a plurality of bolt assemblies arranged at intervals, and because the ground does not have a very high flatness, the distance between each position of the angle steel and the ground can be adjusted by adjusting the bolt assemblies at each position on the angle steel, so that the upper surface of the angle steel can have a higher flatness. In this disclosed embodiment, the length of angle steel is 6m, and the aperture of bolt hole can be phi 10, and the pitch-row between the adjacent bolt hole can be 590mm, and the hole depth can be 60mm, and the bolt hole that is close to the angle steel both ends can be 50mm with the marginal distance of angle steel, correspondingly, the bolt main part can select for use the harness cord screw rod of phi 10.
Since the first nut is an adjusting nut, step S12 may include: and rotating the first nut to adjust the flatness of the upper surface of the angle steel.
Step S13 may include:
s131: erecting a level gauge;
s132: a ruler is arranged on the upper surface of the angle steel; and
s133: and moving the level gauge, and checking the flatness of the upper surface of the angle steel through reading of the staff gauge.
Through the steps S131 to S133, the flatness of the upper surface of the angle steel can be checked, and when the flatness of the upper surface of the angle steel does not reach the standard, the step S12 can be repeated until the flatness of the upper surface of the angle steel reaches the standard.
Step S14 may include rotating the second nut such that the angle is relatively fixed to the ground and the upper surface of the angle is flush with the casting elevation.
In step S2, the surface of the poured concrete is made substantially flush with the upper surface of the angle iron, that is, the surface of the poured concrete is made substantially flush with the pouring elevation.
Between step S2 and step S3, the corner regions of the concrete may be initially flattened manually, and then the concrete may be roughly flattened by a high-precision leveler.
Referring to fig. 3, step S3 may include:
s31: adjusting the flatness of the working surface of the lengthened leveling ruler;
s32: placing two ends of the lengthened leveling ruler on the angle steel on two sides of the angle steel template respectively;
s33: moving the lengthened leveling ruler from one end of the angle steel to the other end, and removing the convex position; and
s34: new concrete is supplied to the recessed locations and leveled by the extended screed.
Wherein the working surface of the lengthened leveling ruler is a surface contacted with concrete. Because the both ends of extension evener are erect respectively at the upper surface of angle steel, consequently, the working face of extension evener can with pour the elevation parallel and level. The constructor can be at the in-process that removes extension evener chi, can be to the saw flat of concrete surface, specifically, can smear the bellied part of concrete surface through extension evener chi, simultaneously, constructor can also observe the depressed part that does not contact with the working face of extension evener chi on the concrete surface, is the part that is less than the elevation of pouring on the surface of concrete to carry out the flattening to these depressed parts supplementary new concrete. Therefore, the flatness of the concrete surface can be rapidly improved by lengthening the leveling ruler.
Between step S3 and step S4, the construction method may further include the steps of:
SA 1: vibrating the concrete;
SA 2: locally scraping the surface of the concrete; and
SA 3: and rechecking whether the actual elevation reaches the pouring elevation.
In step SA1, the concrete may be vibrated by a gasoline vibrating spear so that the concrete is compacted. In step SA2, the constructor may use a heavy type 2m long blade to perform partial scraping to improve the partial flatness. In step SA3, the actual elevation may be checked using a level and a ruler, and if the actual elevation does not match the casting elevation, the previous steps may be repeated until the actual elevation of the concrete surface reaches the casting elevation.
Referring to fig. 4, step S4 may include:
s41: adjusting the flatness of the working surface of the push-pull ruler;
s42: repeatedly performing cross push-pull on the surface of the concrete, and removing the position of the bulge; and
s43: and supplementing new concrete at the sunken position, and leveling the supplemented concrete by a push-pull ruler.
The length of the push-pull ruler can be 3.5m, and the working surface of the push-pull ruler is a surface contacted with concrete. In the case of performing step S4, the concrete has reached an initial set state, and the surface of the concrete has already had a high flatness after the steps before step S4. When the constructor carries out step S42, use push-and-pull chi to alternately push and pull to concrete surface ' S part repeatedly to the standard requirement of checking and accepting according to the roughness carries out the construction of more accurate removal protruding benefit concave flattening to concrete surface ' S each direction, thereby further improves concrete surface ' S roughness.
Further, as shown in fig. 1, after the step S4, the construction method may further include a step S5: and carrying out light receiving construction. Since the use of the glazing disc of the glazing machine in the step S5 may cause damage and disturbance to the flatness of the surface of the concrete, after the step S5, the step S4 may be performed again to restore the damage to the flatness to the maximum extent during the glazing of the glazing machine, and the step S4 is performed again after each step S5 is performed until the flatness of the surface of the concrete reaches the standard.
