内框架砖房和底层内框架砖房的砖柱（墙垛、窗间墙）是该结构中较为脆弱的部

The brick columns (wall stacks, window walls) of the inner frame brick house and the bottom inner frame brick house are the weaker parts of the structure, and the method of forming a composite column by using reinforced concrete sleeves and bricks can be used to strengthen such houses. The method can not only improve the load-bearing capacity of the structure, but also increase the integrity of the house structure at the same time with the method of adding a bolt to the ring beam, tie rod or deep beam end. <br><br>When the combined brick column is reinforced, we must pay attention to the need to tie it with the brick walls on both sides. It can also be embedded in the reinforced concrete along the horizontal joint of the masonry brick and fixed in the fine stone concrete block by anchoring. <br>(3) Columns are added in the reinforced concrete inside the brick wall. This structure can strengthen the brick wall on the one hand, and can also be strengthened for the beam support length is insufficient on the other hand, the cross-sectional width of the inner wall column should not be less than The width of the fixed beam is at least 70mm on each side. The vertical reinforcement of the column is fixed to the longitudinal reinforcement of the beam. At the same time, the mortar anchor or expansion bolt can be used to fix the inside of the beam. One end is fixed to the vertical reinforcement of the column. .

The brick pillars (wall stacks, window walls) of the inner frame brick house and the inner frame brick house on the ground floor are the more fragile parts of the structure, and the reinforced concrete sleeve and brick composite column can be used to strengthen the house, which can not only improve the carrying capacity of the structure, but also increase the integrity of the housing structure at the same time with the ring beam, lever or the method of adding anchor rod at the deep beam end.<br><br>When combining brick pillar reinforcement, it is important to pay attention to its construction with the brick walls on both sides need to be pulled, or can be embedded along the masonry brick horizontal seams and anchored in the fine stone concrete block.<br>(3) The reinforced concrete inside the masonry brick wall, the structure on the one hand can strengthen the brick wall, on the other hand, can be reinforced for the beam support length is not enough, wherein the cross-sectional width of the inner wall column should not be less than the width of the beam fixed with it, and each side width of at least 70mm, wherein the vertical ribs of the column and the girder of the vertical, but also can use the sand screw or flat tube bolt fixed the inner end of the column.

The brick columns (wall buttress, wall between windows) of the inner frame brick house and the inner frame brick house on the bottom floor are the more vulnerable parts of the structure. The method of composite columns composed of reinforced concrete sleeve and bricks can be used to strengthen the house. This method can not only improve the bearing capacity of the structure, but also increase the house structure at the same time with the method of ring beam, pull rod or adding anchor rod at the end of the deep beam The integrity of.<br>When the composite brick column is reinforced, it must be concerned that it needs to be tied with the brick wall on both sides, or it can be embedded in the tie bar along the horizontal joint of the masonry brick and fixed in the fine stone concrete block by anchoring.<br>(3) The reinforced concrete inner column of masonry brick wall can strengthen the brick wall on the one hand, and on the other hand, it can be strengthened according to the insufficient length of beam support. The section width of inner wall column shall not be less than the beam width fixed with it, and the width of each side shall be at least 70mm, in which the vertical bar of the column is fixed with the longitudinal bar of the beam, and the mortar anchor bar or expansion bolt can also be used to fix in the beam, and one end is fixed with the vertical bar of the column.
