Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a wall anti-cracking reinforcement device. Background Art

[0002] Wall cracks are cracks that occur in the wall part of a building structure. According to the different materials themselves, they can be divided into concrete wall cracks, brick wall cracks, new partition board cracks and cracks caused by walls of different materials. In order to prevent the cracks from further expanding and causing damage to the building, it is often necessary to use reinforcement devices to reinforce them.

[0003] A Chinese patent with announcement number CN202215004U discloses a reinforcement structure for a cracked brick wall, including a wall with a crack, reinforcement holes on both sides of the crack, screws passing through the reinforcement holes, and angle steel with holes provided between two studs on both sides of the wall, with nuts screwed on both ends of the studs.

[0004] However, through the above-mentioned existing technology, it can be understood that most traditional reinforcement devices fix screws on the wall along both sides of the crack, and then connect the two screws with nuts through angle steel to fix the wall. Although this traditional reinforcement method can cope with most crack reinforcement problems, for some cracks in the corners of the wall, it is still difficult to handle because it is impossible to install screws to fix the angle steel. Therefore, it is urgent to design a reinforcement structure that can be used to prevent cracks in the corners of the wall. Utility Model Content

The connecting plate 1 can be adaptively adjusted to expand and contract by adjusting the bolts 4 at the adjusting slots 6 of the angle block 2 through the connecting plate 1, and the wall skin that has fallen off around some cracks can be crossed, which facilitates the stable installation of the fixing block 3. According to the direction of the gap at the corner of the wall, multiple devices can be set, and the two adjacent angle blocks 2 are connected by the fixing blocks 3 at both ends of the connecting piece 8, which can improve the overall strength of the angle frame and also prevent the expansion of transverse cracks extending from some longitudinal cracks.

[0030] When assembling multiple angle blocks 2 on the wall, the spacing between the connecting blocks 10 at both ends of the connecting piece 8 can be adaptively fine-tuned according to the actual spacing between the two adjacent angle blocks 2. During adjustment, the adjustment disk 805 at the square hole 804 is used to rotate the stud 806, so that the stud 806 rotates in the slot 803. The rotation of the stud 806 causes the adjustment rod 801 connected by the outer thread to be telescopically adjusted at the slot 803, which can facilitate the adjustment and fixation between the connecting block 10 and the two adjacent concave blocks 7.
