Embodiment 1

[0030]Such asFigure 1 ~ 3As shown, a concrete separation is a simple sewing device including a non-slip handle 1, a large webs 2, and a cutter 3, the anti-skid handle 1 detachably connected to the upper surface of the large sitting 2, the cutter 3 It is detachably connected to the bottom surface of the large disc 2, and the knife 3 of the cutter 3 is disposed vertically from the bottom surface of the large webs 2, and the cutter 3 is opened three-sided exterior with the large sitting 2. 20 mm, the anti-skid handle 1 is hinged to the large adder 2.

Embodiment 2

[0032]Based on the example one, the anti-skid handle 1 includes three sections, each section is 1.8 m, and the total length is 5.4 meters after assembly, the cutter 3 is 60mm, 20 mm wide, and the cutter 3 The total high is the depth of the cutting cut, the cutter 3 is wide as the width of the cutting slit cut, the anti-slip handle 1, the large webs 2, and the cutter 3 are made of magnesium alloy, the anti-skid handle 1 For a telescopic handle, the large woves 2 thickness 10 mm.

[0033]Slitting method of simple seam sections of concrete sections, including the following steps:

[0034]S1. Concrete pouring, forming a concrete pouring road or floor;

[0035]S2. Concrete strength determination, according to the concrete initial time and finalization time, it must be pre-coagulated before the concrete is initiated, and there is no slit before being plastic;

[0036]S3. Positioning, seam spacing generally set distance from 4 meters to 6 meters;

[0037]S4. Application

[0038]S5. Concrete swings, before t...

Abstract

The invention discloses a simple concrete separation joint cutting device and a joint cutting method thereof. The simple concrete separation joint cutting device comprises an anti-skid handle, a large trowel and a joint cutter, the anti-skid handle is detachably connected to the upper surface of the large trowel, and the joint cutter is detachably connected to the bottom face of the large trowel; a cutter body of the joint cutter is perpendicular to the bottom face of the large trowel, joint cutting is conducted through the joint cutter on the simple joint cutting device for the concrete separation joint after initial setting and before final setting of concrete and before plasticity loss, and the joint cutter needs to be moved back and forth repeatedly during joint cutting, so that the forming quality and the light sensation of the concrete and the joint are guaranteed.

Description

Technical field[0001]The present invention relates to the field of road construction techniques, and more particularly to a simple sewing device for concrete separation sections and a sewing method thereof.Background technique[0002]During the construction process, special involves road surface, floor construction, concrete condensed hardening process, cement hydration to release a lot of heat, resulting in elevated concrete temperatures; most cement hydration reaction, concrete temperature begins to decline. In the cooling process, concrete has been coagulated, and the shrinkage caused by cooling can lead to concrete cracking, and the crack direction is relatively random, which seriously affects the road surface, floor quality and service life, and the sewing tool taken in conventional construction is a gasoline cutting machine or The electric sewing machine, its disadvantage includes: 1) noise large, large vibration, manometer is easy to fatigue; 2) Due to constant output power and...
