Description

Technical Field

[0001] This invention relates to a method for reinforcing single-story residential buildings with reinforced mortar strips and its construction, belonging to the field of comprehensive renovation technology for old houses. Background Technology

[0002] With the development of human society, the improvement of productivity, and the advancement of science and technology, building structural design standards are constantly improving, and people are paying more and more attention to the safety of houses. Faced with the large number of masonry structures that exist today, more reinforcement methods have emerged. Considering the advantages and disadvantages of various reinforcement methods, choosing a reasonable, effective, and economical reinforcement method has become a basic requirement for most residents. Using reinforced mortar strips to reinforce single-story houses can not only significantly improve the structural bearing capacity and deformation capacity of single-story houses, but also save on reinforcement costs, while providing a safe and effective reinforcement method and increasing the service life of single-story houses. Using reinforced mortar strips to wrap the end walls, the surfaces of window sills or brick columns, and the eaves of gable walls can significantly improve the in-plane and out-of-plane bending strength, shear strength, and ductility of the walls. Summary of the Invention

[0006] Furthermore, both the vertical and horizontal reinforcing bars are φ8 steel bars.

[0007] Furthermore, the L-shaped anchoring tie bar is a φ10 steel bar.

[0008] Furthermore, the L-shaped anchor tie bar is implanted into the single-story residential wall to a depth of 100mm to 120mm.

[0009] Furthermore, the L-shaped anchoring tie bars are arranged with a horizontal and vertical spacing of 200mm and in a quincunx pattern.

[0010] Furthermore, the thickness of the reinforced mortar strip is not less than 40mm, the thickness of the outer protective layer of the steel bars is not less than 10mm, and the gap between the steel mesh and the wall surface is not less than 5mm.

[0011] Furthermore, the width of the reinforced mortar strip is 600mm.

[0012] The above-mentioned single-story residential buildings are reinforced with reinforced mortar strips, and the construction method is as follows:

[0013] Step 1: Remove the coating from the original exposed brick surface of the wall where the reinforced mortar strip will be installed, remove the mortar joints to a depth of 5mm to 10mm, blow off the surface dust, moisten with water, and spray a layer of neat cement slurry.

[0014] Step 2: Drill holes in the wall according to the drawings, and mark the position of the L-shaped anchor tie bars according to the design requirements.

[0015] Step 3: Drill holes in the wall surface using an electric drill. The diameter of the holes should be 1.25 times larger than that of the L-shaped anchor tie bar, and flush the holes with water.

[0016] Step 4: Install L-shaped anchor tie bars. The L-shaped anchor tie bars are filled with anchoring adhesive. First inject the anchoring adhesive, then insert the L-shaped anchor tie bars. The anchoring depth is 100mm to 120mm.

[0017] Step 5: After the L-shaped anchor tie bars have reached a certain strength in connection with the wall, begin laying the steel mesh.

[0018] Step 6: Lay the steel mesh and weld it to the L-shaped anchor tie bar.

[0019] Step 7: Apply concrete plaster to the reinforced mortar strips on the wall.

[0020] Step 8: Water the reinforced mortar strip for curing, prevent exposure to sunlight, and take antifreeze measures in winter.

[0021] Beneficial effects:

[0022] Because reinforced mortar strips are simple to construct and have low cost, they greatly improve the strength of single-story residential buildings, enabling them to meet seismic requirements, ensuring the safety of single-story residential buildings, reducing personnel and property losses caused by disasters, and increasing the service life of single-story residential buildings.
