Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 , figure 2 As shown, the present invention provides a kind of wall body anti-seismic mortar, comprises body of wall 1 and steel mesh 4, and the metope of body of wall 1 is provided with some evenly arranged holes 2, and hole 2 is inserted with tie bar 3, pulls The tie bar 3 is fixed by the mortar poured into the hole, and the steel mesh 4 is bound on the wall surface through the tie bars 3. The steel mesh 4 includes several cross-shaped steel bars arranged in an X shape, and a mortar layer is sprayed on the wall surface and the steel mesh 4 .

[0027] A number of holes are set on the wall, on the one hand, it is used to insert tie bars to fix the steel mesh, on the other hand, the mortar in the holes can be bonded to the mortar layer, so that the mortar layer has a good affinity to the wall. The wall is rei...

Abstract

The invention provides wall anti-seismic mortar, comprising a wall body and a reinforcing mesh, wherein the wall surface of the wall body is uniformly provided with a plurality of holes, the hole diameter is 20-30 mm, the hole spacing is 100-120 mm, the hole depth is 120-180 mm, tie bars with diameter of 4-8 mm are inserted into the holes and are fixed by the mortar poured in the holes, the reinforcing mesh is tied on a wall surface by the tie bars and comprises a plurality of steel bars arranged in an X shape, and the wall surface and the reinforcing mesh are coated with a mortar layer with thickness of 30-80 mm. The wall anti-seismic mortar has strong structural shear capacity and good structure ductility.

Description

technical field [0001] The invention relates to the technical field of wall mortar, in particular to an anti-seismic mortar for walls. Background technique [0002] In the existing buildings in our country, masonry structure houses account for a relatively high proportion. From previous earthquake investigations, it was found that the earthquake damage of masonry structure houses was very serious. Therefore, research on the seismic reinforcement of masonry structures has important practical value and practical significance. At present, the reinforcement methods of square reinforced mesh concrete plywood wall and square reinforced mesh mortar plywood wall are commonly used in masonry structure reinforcement projects, which can effectively improve the seismic capacity of masonry. However, the masonry structure reinforced with grid steel mesh has insufficient shear resistance and poor structural ductility. Contents of the invention [0003] The object of the present inventi...
