Background
Fair-faced concrete is an expression technique of modern architecture, and is also called decorative concrete because of its excellent decorative effect. The basic idea is that after concrete is poured, operations such as coating, tile pasting, stone pasting and the like are not needed any more, and the plain color of the concrete is only expressed. The clear concrete lacks the decoration work after the form is removed, so the quality of the clear concrete is roughly determined in the form assembling stage.
The decoration on the bare concrete wall is mainly a pattern left by 'construction traces', and comprises decoration holes, exposed seams and cicada seams. The decorative holes are usually split bolt holes, the cicada seams are template splicing seams, and the open seams need special male molds.
However, the construction of the decoration hole has a great problem. The distribution of the decorative holes on the clear water concrete wall is designed in advance, the positions cannot be freely selected according to construction requirements preferentially to ensure the decorative effect, and the positions with high steel bar density such as hidden beams and hidden columns are inevitably met in the construction process. The split screws cannot be installed at the positions and can only be moved to other positions, after pouring is completed, the decorative holes are lost, electric drills and electric saws are needed to pick the decorative holes, the picking of the decorative holes is difficult and time-consuming, the picked decorative holes are extremely poor in appearance and irregular, and the appearance of the decorative holes is particularly obvious in each decorative hole.
If a male die is used for pouring the missing decorative holes, two problems are faced, one of the two problems is a fixed problem, because the part where the split screw cannot be installed in construction is not fixed, the male die needs to be detachably fixed on a wall template, but the male die is difficult to ensure to be stable in the pouring process by the conventional fixing mode, and if the male die is not stable in the pouring process, the poured decorative holes are deformed; the second problem is the problem of form removal, the decorative hole is a hole with a certain depth (much deeper than the open joint), so the male die for pouring the decorative hole faces the problem of difficult form removal, and as the decorative hole needs to be ensured to be regular, the male die can not be violently removed, and a core die made of filler can not be adopted (the decorative hole poured by the core die is serious in shape walking, and needs to be trimmed after pouring).
