Abstract

The invention relates to a concrete pouring leveler, comprising an inner leveler (1) and an outer leveler (2). The outer leveler (2) is in the shape of a rectangular groove, and handles are provided at both ends of the leveler. The inner leveler (1) has a cuboid hollow structure, and handles are provided at both ends thereof, and the inner leveler (1) can be placed in the groove of the outer leveler (2). Compared with the prior art, the present invention adopts a steel structure nested double leveler, which has reasonable design, novel structure, simple operation, convenient disassembly and transportation, and takes up little space. At the same time, the steel structure is self-heavy, which can have a good smoothing effect, and levelers or combinations of different weights can be selected for smoothing work according to engineering requirements.

Description

concrete pouring leveler

technical field

The invention relates to tools related to leveling operations in the construction field, in particular to a concrete pouring leveler.

Background technique

One of the key points of quality control in the track slab production process is to maintain high flatness and high precision. The requirement for high flatness of the track slab is mainly because the fasteners are directly installed on it. The flatness of the track slab will directly affect the laying quality of the rails on it. Poor flatness of the track slab will cause the rail to hang empty or affect the seamless railway. The smoothness of the train will affect the smoothness, comfort and safety of the subsequent train operation.

This high requirement for flatness is jointly guaranteed by two aspects: first, the requirement for flatness of the mold. At present, the flatness requirement for high-speed rail track slab molds in my country is ±0.3mm. The key point of quality control during the construction process is the processing of the model. In terms of manufacturing and model acceptance, a qualified model is the basis for ensuring high flatness and high precision of the track slab; on the other hand, after the pouring and vibration work is completed, it is necessary to manually use a concrete pouring leveler to smooth the concrete surface and fill in the edges. Only by filling the corners can the overall flatness requirements of the track slab be guaranteed.

In the field of related concrete construction, large-scale concrete leveling machines and driving trowels are often used for leveling operations. Large-scale leveling machines are not suitable for high platform operations in track slab production, so the present invention is specially used for pouring concrete in the track slab production process. Used for final leveling of the track slab surface.

Contents of the invention

The object of the present invention is to provide a concrete pouring leveler in order to overcome the above-mentioned defects in the prior art.

The purpose of the present invention can be achieved through the following technical solutions: a concrete pouring leveler, characterized in that it includes an inner leveler and an outer leveler, the outer leveler is in the shape of a rectangular groove, and handles are provided at both ends , the inner leveler can be placed in the groove of the outer leveler.

The inner leveler is a cuboid hollow structure with handles at both ends, both of which are of steel structure and welded to both ends of the main body. The thickness of the inner leveler is smaller than that of the outer leveler.

The outer leveler is welded to the handles at both ends. The outer leveler is bent at high temperature to form a grooved main body. The two handles are both steel structures and welded to both ends of the main body.

Both the inner leveler and the outer leveler are of steel structure, and the weight of the inner leveler is smaller than that of the outer leveler.

During use, inner and outer levelers of different weights or a combination of inner and outer levelers can be selected for smoothing work according to engineering requirements and product precision requirements.

Compared with the prior art, the concrete pouring leveler of the present invention is used in the concrete pouring link in the production process of the high-speed rail track slab. After the vibrating work is completed, the workers use the invention to perform smoothing operations on the poured concrete surface, so that The poured concrete is evenly distributed within the range of the mold, the excess concrete is removed, and the parts not poured are smoothed, so as to ensure the high flatness of the surface of the track slab.

detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Example 1

As shown in Figures 1 to 3, a concrete pouring leveler includes an inner leveler 1 and an outer leveler 2, the outer leveler 2 is in the shape of a rectangular groove, and handles are provided at both ends: handle 3 and handle 4. The inner leveler 1 can be placed in the groove of the outer leveler 2 .

The inner leveler 1 is a cuboid hollow structure with handles at both ends: a handle 5 and a handle 6, and the thickness of the inner leveler is smaller than that of the outer leveler.

The outer leveler 2 is welded to the handles at its two ends. The outer leveler is bent at high temperature to form a grooved main body. The two handles are both steel structures and welded to both ends of the main body.

Both the inner leveler 1 and the outer leveler 2 are steel structures, and the weight of the inner leveler 1 is smaller than that of the outer leveler 2 .

When in use, according to engineering requirements and product precision requirements, select inner and outer levelers or a combination of inner and outer levelers of different weights, place them on the mold that has been poured, and place them parallel to the short side of the mold. Two workers hold the handles respectively. 3 and handle 4 (or handle 5 and handle 6), smoothing from one side of the mold to the other side, can be used repeatedly if necessary, and the type of leveler can be replaced or the combination of inner and outer levelers can be used to continue the leveling work .
