Abstract
Description
Technical Field
[0001] The invention relates to the technical field of plain concrete, in particular to a tool for processing construction joints of plain concrete on an inclined surface. Background Art
[0002] Fair-faced concrete is a form of architectural modernism, and is also called decorative concrete because of its decorative effect. The basic idea is that after the concrete is poured, there is no longer any coating, tile, stone or other materials, which is a way to show the plainness of concrete.
[0003] In industrial and civil construction projects, large-scale plain concrete structures are increasingly widely used. Due to the limitations of wet concrete operations, joints are bound to exist between formworks during cast-in-place concrete construction. The main treatment method for formwork joints in the prior art is to paste sponge strips before splicing the formworks. This formwork joint treatment method is simple, but the joints at the formwork joints are not tight, which can easily cause mortar leakage at the joints during concrete pouring, affecting the visual quality of plain concrete.
[0004] The existing patent document CN217480813U discloses a kind of fair-faced concrete decorative open seam strip, which has a T-shaped cross-section; the fair-faced concrete decorative open seam strip comprises a panel and a web, the panel and the web are both long strips, the web is vertically connected to the middle of the back of the panel, and the two ends of the panel and the web are flush; the back of the panel is provided with a sealing elastic layer, the thickness of the sealing elastic layer is 1.5-2.5mm; the panel is provided with screw through holes. The back of the panel of the fair-faced concrete decorative open seam strip of the utility model is provided with a sealing elastic layer, when the template is spliced, the sealing elastic layer of the fair-faced concrete decorative open seam strip is elastically pressed with the template, so that the concrete slurry does not leak between the template and the fair-faced concrete decorative open seam strip, and the two templates form a whole, so the formed decorative open seam is regular and beautiful, and has a good decorative effect. However, the patent document still has the following problems:
[0005] 1. The exposed seam strip has a fixed structure and a single decorative effect, which cannot form a variety of decorative effects.
[0006] 2. The exposed seam strip is fixed to the formwork by screws, and the screws need to be tightened each time it is used, which makes the exposed seam strip unsuitable for long-term use and causes damage to the formwork.
[0007] 3. The exposed seam strip can only be used between adjacent formworks, but has no specific effect on the cross-intersection positions between formworks. However, the cross-intersection positions of the exposed seams are still the key areas for the decorative effect of fair-faced concrete. Utility Model Content
