Embodiment Construction

[0023] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0024] Such as Figure 1 to Figure 4 Shown, a kind of wall corner crack repair method, comprises the following steps:

[0025] Step 1: Find the location of the crack in the corner of the wall, and then dig a repair groove 1 at the crack. After repairing the groove 1, the contact area between the repairing cement and the wall can be increased, and after opening the repair groove 1, the gap between the two walls can be increased. Leave enough space to place connecting square pipe 3 and excavate reinforcement hole 2.

[0026] Step 2: Dig reinforcement holes 2 on both sides of the repair groove 1, and drill reinforcement holes 2 on the side of the repair groove 1 with tools such as an electric drill, so that the reinforcement bars 4 can enter the wall.

[0027] Step 3: Put the connecting square pipe 3 in the repair groove 1, drive th...

Abstract

The invention discloses a wall corner crack repairing method. The wall corner crack repairing method comprises the following steps that step 1, the position of a wall corner crack is found, and then arepairing groove is dug at the crack; step 2, reinforcing holes are dug on both sides of the repairing groove; step 3, a connecting square tube is placed into the repairing groove, and reinforcing steel bars are inserted into the reinforcing holes from the upper part of the connecting square tube; step 4, the reinforcing steel bars and the connecting square tube are welded, and the reinforcing steel bars are welded; and step 5, dust in the repairing groove is cleaned, and the repairing groove is filled with cement, leveled up and compacted and the surface of the repairing groove is leveled. The wall corner crack repairing method embeds the reinforcing steel bars in the wall body crack, the connecting square tube is used for reinforcement, the strength of a wall body is improved, the probability of the wall body cracking again is effectively reduced, the steps of the method are simple, the construction is safe, the structural reliability after the reinforcement is high, and the use time of a building can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of wall crack repair, in particular to a method for repairing wall corner cracks. Background technique [0002] The wall is a vertical component of the building structure. Generally, it does not store water, does not accumulate water, and is not prone to leakage. However, factors such as rough construction, improper material selection, improper use by users or poor management will cause cracks in the wall, resulting in leakage. The main reasons for cracks in the wall are: the low strength grade of masonry mortar, improper use of mortar types, and poor control of the mix ratio, etc., which reduce the strength of the wall, poor masonry integrity, and premature weathering; Cracks are caused by open joints, empty joints and blind joints that are not dense, not full, or caused by wrong masonry methods. Due to the relatively concentrated stress, cracks are prone to occur at the corners of the wall. Therefore, how...
