RU2555995C1 - Method for grouting decorative facing of concrete structures - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: U-shaped metal profile with anticorrosive coating, which is installed at the beginning of joint at an angle of α=5-10°, and then subjected to impact up to its complete embedding, is used as a filler in the method for grouting the decorative facing of concrete structures, which includes installation of facing panels on the concrete structure, trimming of the formed joints and application of filler.

EFFECT: reduction of labour intensity of grouting and quality improvement.

Description

The invention relates to the construction industry and may find application in the facing of facade concrete structures of buildings and other structures.

A known method of filling seams (grooves) between concrete structures, including placing on the surface of a previously constructed concrete structure a casing in communication with injection hoses or channels and marking its position so that the marking is visible after the manufacture of the second concrete structure, in which, after hardening in accordance with with marking, a hole is drilled passing through a casing concreted in it, and through the holes formed, sealing material is introduced into the casing, from the casing into injection hoses and channels (see IPC E04B 1/68 for a description of the invention to Patent No. 2100534 of the Russian Federation, publ. 12/27/1997).

The disadvantage of this method is its high complexity.

Closest to the claimed technical solution is a method of filling the joints of the decorative cladding of concrete structures, including mounting decorative plates on the concrete structure, cleaning the joints from contamination, wetting and applying the filler in the form of grout with a syringe - a gun or a special spatula, followed by removal of excess and ramming the joints (see installation instructions “Polystyrene foam boards with decorative cladding for facade systems”, available on the website http://liderfasada.ru/) - the closest ALOGIA.

The disadvantage of this method is the high complexity while at the same time low filling strength of the joints. The maximum strength with this technology is achieved only after 5 days, provided that there is no precipitation. In addition, the quality of the grout and the condition of the edges of the tiles can lead to a change in the color of the filled joints.

The technical result of the proposed method is to reduce the complexity of filling the seams and improving the quality.

The essence of the technical solution lies in the fact that in the method of filling the joints of decorative cladding of concrete structures, including mounting the facing panels on the concrete structure, cleaning the formed joints and applying the filler, a U-shaped metal profile with an anti-corrosion coating is used as a filler, which is installed at the beginning the seam at an angle α = 5-10 °, and then subjected to shock until it is completely sunk.

Using a metal profile allows you to reduce the complexity from 5 days to several hours. The U-shaped shape of the profile ensures its reliable fixation in the seam after impact and eliminates the subsequent expansion of the seam, which takes place in known analogues.

The installation of the profile at the beginning of the seam at an angle α = 5-10 ° eliminates its displacement during impact, which increases the quality of filling. If the angle α <5 °, an additional technological operation is required to introduce the profile edges into the space between the plates, and if the angle α> 10 °, the probability of deformation of the profile increases during the operation associated with recessing the profile.

The proposed method of filling the joints of decorative cladding of concrete structures is illustrated by drawings, where in Fig.1 shows a General view of a concrete structure without a metal profile; figure 2 is a General view of a concrete structure with an installed metal profile; figure 3 is a metal profile; figure 4 - metal profile at the beginning of the seam at an angle to the impact.

The method is as follows. Depending on the length and width of the concrete structure 1, its configuration selects the required number of panels 2 of decorative cladding 3. Installation of panels 2 is carried out in accordance with the pattern of decorative cladding 3. Before filling the seam 4, the edges of panel 2 are cleaned, a metal profile 5 is cut, cut to the size of the fill seam 4. Profile 5 is inserted at the beginning of seam 4 with a small angle α °, for example 5 °, to the filled seam 4 and is subjected to light impact, for example, a wooden or polyurethane mallet as the follower drowns but along the entire length of the seam 4. Then produce a control "tapping" profile 5 along the entire length.

Unlike the closest analogue, the inventive method allows filling seams in a short period of time. If in the known method of filling the seam of one panel until complete readiness is 5 days, then in the proposed method this time is reduced to 15-20 minutes with high reliability and strength of filling the seam.

Moreover, the inventive method has a high maintainability, as it eliminates the possibility of damage to the panels if you need to replace any of its plates. The coating of the metal profile can also be decorative.
