Description

Novel large-area terrace concrete pouring process

Technical Field

The invention relates to the technical field of concrete pouring, in particular to a novel large-area terrace concrete pouring process.

Background

Along with the increasing scale of industrial plants, the building area of the plants is larger, and the difficulty and the cost of building floor pouring of the plants are increased. How to realize the 'good' and 'province' of terrace pouring becomes the core problem of terrace pouring. The traditional terrace pouring construction process is limited by the operation of the roller, so long as the terrace width is larger than 6m, the terrace can be poured twice or more, the second pouring can be continued only by requiring the first pouring concrete surface layer to bear the load of the next construction procedure, and the construction speed is difficult to improve.

step 1: cutting the steel bar with the diameter of 12mm into two specifications of 40cm and 10cm, wherein the number is determined according to the floor area;

step 2: welding the middle part of a 10cm steel bar at a position 3cm away from the upper end of a 40cm steel bar, wherein the 10cm steel bar is vertical to the 40cm steel bar to form a cross-shaped iron piece;

and step 3: driving the crossed iron pieces into the foundation on the terrace according to a plurality of roads, wherein the distance between every two roads is 6m, the interval distance between every two roads is 2m, and the driving depth is specifically determined according to the thickness of the terrace;

and 4, step 4: placing a ruler on the upper part of a 10cm reinforcing steel bar, leveling each cross-shaped iron piece by using a level gauge, measuring data which is 48mm lower than the surface of the poured terrace, and reinforcing the concrete of each cross-shaped iron piece after each measurement;

and 5: placing straight steel pipes with the length of 6m on the left side and the right side of the upper part of the cross-shaped iron piece, and firmly binding the steel pipes by binding wires;

step 6: and (3) pouring concrete at one time, strickling off along the steel pipe by using a 6m strickling-off tool, taking out the steel pipe and the binding wire after strickling off, and strickling off by using a 2m strickling-off tool.

Compared with the prior art, the invention has the beneficial effects that: the floor is not affected by the area and times, the whole workshop floor can be poured in place at one time, and the time is saved by more than one time at least.

Detailed Description

The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in the figure, the concrete pouring process of the novel large-area terrace comprises the following specific steps:

step 1: cutting the steel bar with the diameter of 12mm into two specifications of 40cm and 10cm, wherein the number is determined according to the floor area;

step 2: welding the middle part of a 10cm steel bar at a position 3cm away from the upper end of a 40cm steel bar, wherein the 10cm steel bar is vertical to the 40cm steel bar to form a cross-shaped iron piece;

and step 3: driving the crossed iron pieces into the foundation on the terrace according to a plurality of roads, wherein the distance between every two roads is 6m, the interval distance between every two roads is 2m, and the driving depth is specifically determined according to the thickness of the terrace;

and 4, step 4: placing a ruler on the upper part of a 10cm reinforcing steel bar, leveling each cross-shaped iron piece by using a level gauge, measuring data which is 48mm lower than the surface of the poured terrace, and reinforcing the concrete of each cross-shaped iron piece after each measurement;

and 5: placing straight steel pipes with the length of 6m on the left side and the right side of the upper part of the cross-shaped iron piece, and firmly binding the steel pipes by binding wires;

step 6: and (3) pouring concrete at one time, strickling off along the steel pipe by using a 6m strickling-off tool, taking out the steel pipe and the binding wire after strickling off, and strickling off by using a 2m strickling-off tool.

The horizontal point of the traditional terrace method is determined on the channel steel, the concrete is poured on the surface layer of a single strip, and leveling can be achieved, but elevation of the concrete after the concrete is condensed on the concrete surface layers of more than two paths has errors due to various reasons, such as the proportion of water in the concrete, deviation of a template and the like, the terrace pouring between the two paths of the second time is completely based on the concrete height after the concrete is poured on two sides, the elevation point has errors, and because the terrace is not poured once, errors are bound to exist in the joint position after the concrete surface layer poured for the second time is condensed, the traditional method is not well controlled, the unevenness of the concrete surface is easy to occur, the joint position is obvious and other defects. According to the method, firstly, straight 6m steel pipes are placed on three iron pieces with flat elevations at intervals of 2m, the tops of all the steel pipes are on the same horizontal plane, the intersection positions of the two steel pipes can be checked to be more accurately adjusted, then the whole workshop terrace can be integrally cast, dense elevation control points enable the surface flatness to reach 100%, and the connection flatness can also reach 100% due to the fact that the steel pipes are not cast successively.

The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and such improvements and modifications are also considered to be within the scope of the present invention.
