Background
Under the general condition, the concrete terrace area reaches 20 square meters, then joint cutting construction is needed to prevent the terrace from deforming or shrinking due to temperature or humidity changes, so that the terrace is cracked or locally deformed, and the joint cutting can relieve the shrinkage stress of the terrace and avoid the terrace from cracking or deforming. In the traditional large-area concrete terrace construction, wood purlin and the like are often adopted as mould partitions and blocks for concrete pouring, in the concrete pouring process, the ground target-out, the target-drawing elevation line, the infrared elevation, the level gauge elevation and the like are adopted to control the terrace pouring elevation and flatness, and secondary joint cutting treatment is carried out after the concrete pouring is completed. Such a method has the following drawbacks: 1. in the concrete pouring process, the control of the concrete elevation and the flatness often depends on the condition of empirical construction, the methods of elevation control points, elevation lines and the like are too dependent on manual measurement, and the traditional elevation control methods all have the condition of point control surfaces, so that the quality problems of poor forming flatness, inaccurate elevation and the like occur in the construction of a large-area concrete terrace; 2. the traditional large-area concrete terrace construction needs secondary joint cutting treatment, so that the joint cutting quality is difficult to ensure while the manual loss is increased, and the quality problems of insufficient joint depth, over-deep joint depth, unsophisticated joint cutting and the like exist.
In the prior art, as disclosed in patent application number 202022609873.6, a reusable concrete pavement expansion joint separation device comprises a joint plate, a top plate perpendicular to the joint plate, and sleeves and prying bars at two ends of the top plate, wherein the joint plate is a vertical steel plate of 3000 x 200, and the top plate is a transverse steel plate of 3000 x 100 x 3. In the construction process of the concrete road, the expansion joint device separates concrete sections through steel plates, so that concrete generates regular and vertical gaps, and the parting plates are taken out by using a crow bar during initial setting of the concrete. According to the utility model, the extrusion particles are arranged on the two side surfaces of the parting plate, so that the extrusion particles are taken out after the concrete section is dried, and the prepared concrete side surface is large in groove and convenient to connect and fix. The patent also has the following problems:
1. the parting plate is not fixed, the impact force during concrete grouting, the pressure of concrete flowing and the vibration frequency during concrete vibrating are large, the parting plate is easy to shift, the pavement gap is inclined, the gap molding does not reach the standard, and the pavement is not attractive;
2. the slit plate is fixed in height, cannot actively adapt to concrete terrace pouring construction with different thicknesses, and for concrete terrace pouring with overlarge or overlarge thickness, the depth of a slit after pouring of the slit plate does not reach the standard;
3. if the height of the template is higher than the casting height of the pavement, the device is difficult to position the height position, and if the top plate is fixed at the top end of the casting template, the fact that the parting plate stretches into the concrete mortar to too shallow depth or does not stretch into the concrete mortar easily occurs;
4. When constructors scrape the surface of the poured concrete mortar, the handles on the top plate can block the constructors, so that the constructors can only scrape the surface in different areas, the height of the mortar in the two areas is inconsistent easily, and the concrete forming evenness and elevation accuracy cannot meet the design requirements.
