Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a paving device for cement fiber composite slurry. Background Technique

[0002] After fibers are incorporated into concrete, the improvement effect on the compressive, tensile and flexural strengths of concrete is not significant, but it can significantly improve the dynamic properties such as impact resistance and fatigue resistance of concrete, and improve the dynamic load-bearing capacity of concrete. The incorporation of fibers is also beneficial to the durability of concrete. It can effectively inhibit the early cracking of concrete and the further expansion of microcracks, reduce the shrinkage cracks of concrete, especially effectively inhibit the generation of through cracks, reduce the porosity of concrete, and improve the density and waterproof performance of concrete. The main varieties of common fiber concrete include steel fiber concrete, glass fiber concrete, polypropylene fiber concrete, carbon fiber concrete, plant fiber concrete, high elastic modulus synthetic fiber concrete, etc.

[0003] However, due to the large density difference between the fibers and the cement slurry material, during the thin-layer paving construction of the cement fiber composite slurry, the fibers usually float on the upper layer of the slurry, resulting in the following two problems: First, after the cement / fiber composite slurry is paved, a large amount of aggregated fibers will appear on the surface, which will affect the surface flatness and overall aesthetics; Second, the fibers are not evenly dispersed, resulting in poor mechanical properties after the hydration of the cement fiber composite slurry and affecting the service life.

[0004] Therefore, it is necessary to develop a paving device for cement fiber composite slurry that can disperse the cement fiber composite slurry. Content of the Utility Model

[0005] In view of the above technical problems existing in the prior art, the utility model provides a paving device for cement fiber composite slurry, which can disperse the cement fiber composite slurry and avoid the aggregation of fibers on the surface after paving.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: after the cement fiber composite paste is discharged from the discharge port of the mixer, it is paved by the paving mechanism.

[0027] The paving equipment for cement fiber composite slurry, such as Figures 1 - 4 , includes a tractor 1, a mixer 2, a paving mechanism 3 and an oscillating mechanism 4. The mixer 2 is installed at the rear side of the tractor 1. A paving mechanism 3 is arranged on one side of the discharge opening 21 of the mixer 2; an oscillating mechanism 4 is arranged at the rear side of the paving mechanism 3.

[0028] After the cement fiber composite slurry is discharged from the discharge opening of the mixer 2, it is paved through the paving mechanism 3. While the tractor is moving forward, the oscillating mechanism oscillates the slurry through the oscillating slide plate 46, so that the fibers of the slurry are evenly dispersed and do not float on the surface of the slurry. The flatness and aesthetics of the surface are improved, and the mechanical properties after the hydration of the slurry are improved.

[0029] Wherein, the oscillating slide plate 46 has an arc-shaped structure.

[0030] A texturing mechanism 5 is arranged at the rear side of the oscillating mechanism 4. The anti-slip performance of the slurry after oscillation is improved, and the driving safety of the road surface is improved. Such as Figure 3 , a texturing roller 52 is arranged at the lower side of the texturing mechanism, and texturing members 51 are arranged on the outer periphery of the texturing roller 52.

Any one of the following paving plates is provided on the lower side of the paving mechanism 3: a first paving plate 31 and a second paving plate 32; a plurality of square structures are provided at intervals at the lower end of the first paving plate 31; a toothed structure is provided at the lower end of the second paving plate 32.

[0032] A feeding port 35 is provided on the front side of the paving mechanism 3, and the discharge port 21 is matched with the feeding port. After the slurry falls from the discharge port 21 and the feeding port 35 to the ground, the tractor moves forward, and the paving mechanism passes through the slurry on the ground to pave the slurry.

[0033] Figure 4 The specific installation structure of the specific vibration mechanism is shown. An installation frame 33 is provided on the tractor 1, and the paving mechanism 3 is installed on the lower side of the installation frame 33.

[0034] Based on a large number of indoor and outdoor tests and construction experience, the utility model develops a thin-layer paving device for cement fiber composite slurry, which solves the complex construction problems of fiber aggregation and floating on the surface of the slurry, and poor anti-skid performance of the concrete pavement at the same time.

[0035] The utility model can perform fully automated operations with the cooperation of the main control cabinet, various sensors and control motors. And it can complete operations such as stirring, paving, leveling, and texturing in one paving operation, greatly improving the paving efficiency of the thin-layer paving device for cement / fiber composite slurry and the quality of the cement layer formed by paving. It is applicable to the repair and patching construction of 3-30 mm cement fiber composite slurry. Compared with the prior art, in the construction process of this device, the stirring step, the paving step, the leveling step and the texturing step can be carried out simultaneously, thus greatly increasing the efficiency of paving cement.

[0036] During construction, the slurry flows from the mixing tank to the ground. The spreading plate disperses the slurry on the road surface.

The utility model can perform large-area spreading construction, ensure the uniform spreading of cement mortar, and at the same time, it does not require workers to hold it by hand, greatly reducing the labor intensity of workers. When spreading cement mortar, turning the handle drives the threaded shaft to rotate. At this time, the moving plate can be moved, and then the spreading plate slides inside the main pipe. At this time, the length of the spreading plate can be extended, and then the spreading width can be extended according to the actual situation, expanding the spreading area of cement mortar and adjusting according to the actual ground length, thus expanding the scope of use.
