After removing the bubbles, it is manually smoothed to make the surface of the prefabricated parts formed on the mold smooth and clean, and finally dry and solidify. The whole process is time-consuming and labor-intensive, and also seriously affects work efficiency. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0023] Embodiment 1, as Figure 1-5 As shown, a debubble and smoothing integrated tool for UHPC pouring includes a connecting handle 1, on which a debubble assembly and a smoothing and smoothing assembly are respectively installed;

[0024] The bubble removal assembly includes two connecting blocks 2 and a fixed block 3. The two connecting blocks 2 are detachably mounted on the front and rear sides of the fixed block 3. The lower surfaces of the two connecting blocks 2 are fixedly mounted with roughening nail teeth 4. The left and right ends of the fixed block 3 are provided with through holes in the vertical direction. The through holes are equipped with adjusting screw assemblies 5. The lower ends of the adjusting screw assemblies 5 pass through the fixed block 3 and are fixedly connected with support plates 6. The support plates 6 are supported on the side molds at both ends of the mold 10. The middle of the fixed block 3 is fixedly connected to the connecting handle 1 through connecting bolts.

[0025] The scraping and troweling assembly comprises a troweling scraper 7 , and two ends of the troweling scraper 7 are respectively mounted on the side molds at two ends of the mold 10 .

[0026] Working principle:

[0027] When in use, the two connecting blocks 2 can be respectively installed on the front and rear sides of the fixed block 3, and then the bubble removal component and the leveling and troweling component are placed above the mold 10, and then the relative height of the fixed block 3 is adjusted by adjusting the screw assembly 5, so as to control the depth of the roughening nail teeth 4 embedded in the mold 10 for casting UHPC; and then the fixed block 3 is supported on the side molds at both ends of the mold 10 by the support plate 6, and the two ends of the troweling scraper 7 are also respectively mounted on the side molds at both ends of the mold 10. Therefore, during use, after the UHPC is cast, the tooling is tilted forward 45 degrees, and then by pulling the connecting handle 1, the UHPC is firstly uniformly roughened and stirred by the densely-packed roughening nail teeth 4, so that the microbubbles distributed in the UHPC slurry can be punctured and removed during the combing. Then, the troweling scraper 7 is used to level and smooth the surface of the UHPC that has just been debubbled, so as to achieve the same smooth surface effect as the surface. The whole process is convenient and fast, which can effectively reduce the working procedures and manpower, save production time, and thus effectively eliminate bubbles and improve construction efficiency during the UHPC component manufacturing process.

[0028] Embodiment 2, as a further preferred solution of embodiment 1, at least two connecting rods 8 are evenly arranged between the trowel blade 7 and the fixed block 3, and the two ends of the connecting rod 8 are respectively fixedly connected to the trowel blade 7 and the fixed block 3 by fixing bolts. The trowel blade 7 and the fixed block 3 are connected and fixed by the connecting rod 8, thereby effectively ensuring that the trowel blade 7 and the fixed block 3 can move relatively stably.

[0029] Embodiment 3, as a further preferred embodiment of embodiment 1, two groups of roughening nail teeth 4 respectively located on two connecting blocks 2 are arranged alternately. By staggering the two groups of roughening nail teeth 4, the roughening and stirring of the UHPC slurry can be performed more evenly.

[0030] Embodiment 4, as a further preferred solution of embodiment 1, the front and rear sides of the fixing block 3 are provided with T-shaped grooves, the side of the connecting block 2 is provided with T-shaped protrusions 9, and the connecting block 2 is inserted into the T-shaped grooves through the T-shaped protrusions 9. Therefore, when in use, the connecting block 2 can be directly inserted into the T-shaped grooves on the side of the fixing block 3 through the T-shaped protrusions 9, so that the connection block 2 and the fixing block 3 can be installed and fixed.

[0031] Embodiment 5, as a further preferred embodiment of embodiment 1, the adjusting screw assembly 5 includes a screw 51, a first bolt 52 and a second bolt 53, the end of the screw 51 is connected to a support plate 6, the first bolt 52 and the second bolt 53 are respectively connected to the outer surface of the screw 51 by threads, and the first bolt 52 and the second bolt 53 are respectively located on the upper surface and the lower surface of the fixing block 3.

[0032] Therefore, when it is necessary to adjust the relative height of the fixing block 3, the first bolt 52 can be loosened upwards first, and then the second bolt 53 can be rotated to drive the fixing block 3 to move axially relative to the screw rod 51, thereby achieving the effect of adjusting the relative height of the fixing block 3. After adjusting to a suitable position, the first bolt 52 is tightened downwards, so that it can cooperate with the second bolt 53 to lock and fix the fixing block 3.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
