Technical Field
The invention relates to the field of buildings, in particular to a rear-mounted anchor net and an operation method thereof.
Background
The wall body of the building engineering is mostly formed by building blocks, and a plurality of building blocks need to be anchored with a main framework (such as a reinforced concrete column) of the building so as to meet the integral requirement of earthquake resistance. Most of the current anchorages are realized by reserving tie bars during the construction of the main frame. The scheme has the problems that:
(1) the positions of reserved steel bars are often not matched with the positions of seams of materials used for the masonry;
(2) when a wall body is built, the connecting end of the reserved steel bar is often required to be bent at a right angle, so that the bending difficulty is high, the bearing deformation is easy to cause, the corresponding building joint is increased, and more problems are caused;
(3) reserved ribs need to drill hole positions in a pouring template, and the hole positions are often the main reason for causing slurry leakage around the ribs;
(4) drilling out the hole site of reserving the muscle on pouring the template, can directly harm the template face, bring very adverse effect to the follow-up use of template.
(5) The reserved ribs cannot be made into a hook shape in advance, so that the anchoring tension of the reserved ribs in the building is reduced;
(6) the anchoring force of the reinforcement in the mortar joint is reserved, and the bonding force of mortar around the reinforcement is far smaller than the anchoring force of the reinforcement in concrete when the mortar joint is smaller, so that the performance of the building material is difficult to exert.

Preferably, the lower arc body and the upper chord arc body are provided with a plurality of barbs, the barbs at the front end are larger, and the barbs at the rear end are smaller. The front end is the end extending into the deep part of the hole and is the front end, and the rear end is the end extending into the shallow part of the hole and is the rear end.
Preferably, the plurality of transverse anchoring strips are transversely welded to the rear parts of the longitudinal anchoring strips in an up-down staggered manner.
The operation method of the rear anchoring net piece comprises the following steps:
(1) according to the anchor seam position of the wall body, marking a drilling hole position on the component;
(2) drilling according to the mounting size of the anchor end of the rear anchor net sheet;
(3) cleaning and moistening the holes;
(4) installing an anchor end with cement slurry;
(5) the wedge body is pushed into the space between the lower arc body and the upper chord arc body through a tool, so that the anchor knot end is extruded in the hole, and at the moment, the arc convex ribs and the barbs of the lower arc body and the upper chord arc body are extruded into the hole wall.
The invention has the beneficial effects that: according to the invention, the traditional pre-embedded anchoring mode is changed into a mode of firstly forming the component and then drilling and anchoring, so that the anchoring tension can be enhanced, the rear anchoring net piece can be integrally anchored with the wall, the mortar binding force is greatly improved, and the requirements of different wall body pulling knots are met. The post-anchored mesh can be produced industrially, has high quality and less field labor, and is favorable for industrialization.
