Description

Technical Field

[0001] The utility model relates to a masonry structure wooden column reinforced by adding a wall, belonging to the technical field of comprehensive reconstruction of old houses. Background Art

[0002] At present, there are still many old masonry houses with wooden columns, which will be damaged to varying degrees due to their age. For example, if the bottom of the wooden column is rotten, cracked by force or eaten by insects, etc., the wooden column with serious damage should be replaced by new wooden columns, brick columns or reinforced concrete columns when it is renovated. When the quality of the wooden column is good, there is no serious damage such as rot, cracked by force or eaten by insects at the bottom, and the bearing requirements are met, the wooden column should be reinforced by steel wrapping, brick column wrapping (adding wall), reinforced concrete frame, steel frame and other measures in combination with the front longitudinal wall. The utility model adopts the form of adding wall to carry out earthquake-resistant reinforcement for the wooden column of masonry structure, which can improve the overall earthquake resistance of the original structure, make the new and old structures bear the earthquake together, thereby enhancing the toughness of the house and preventing the collapse of the structure. The method of reinforcing the wooden column of masonry structure by adding wall is simple in construction, reasonable in structural force, and has good economic and environmental benefits. Utility Model Content

[0006] Furthermore, the ∝-shaped tie steel bar is a HPB300 grade hot-rolled steel bar.

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

[0008] Furthermore, the overlap length between the ∝-shaped tie steel bar and the rear-added wall is not less than 240 mm.

[0009] Furthermore, the ventilation and drainage holes are square holes of 20 mm×20 mm.

[0010] Furthermore, the thickness of the rear-added wall is 240 mm.

[0011] The above-mentioned method of reinforcing a masonry structure wooden column by adding a wall and a construction method thereof adopts the following steps:

[0012] Step 1: Make ∝-shaped tie bars;

[0013] Step 2: Wrap the bottom of the log column with C30 concrete and reserve ventilation and drainage holes;

[0014] Step 3: After the concrete reaches a certain strength, the wall blocks are laid according to the design drawings, and the log columns are wrapped in the rear wall;

[0015] Step 4: After the added wall reaches a certain height, arrange the ∝-shaped tie bars according to the design drawings and reserve window openings;

[0016] Step 5: After all the additional walls are built, plaster and level the walls.

[0017] Beneficial effects:

[0018] The most significant advantage of the utility model is that the use of additional walls to reinforce the masonry structure wooden columns can improve the overall earthquake resistance of the original structure, so that the new and old structures can jointly bear the earthquake effect, thereby enhancing the toughness of the house and preventing the structure from collapsing. The method of using additional walls to reinforce the masonry structure wooden columns is simple to construct, the structural force is reasonable, and it has good economic and environmental benefits.
