Description

  The present invention relates to a precast bearing wall connection structure in which a bearing wall structure having further hardness is formed by an arrangement of a new type of reinforcing bar structure.

  As shown in the prior art of FIG. 1, the traditional load-bearing wall connecting structure includes a first load-bearing wall 200 and a second load-bearing wall 300. The connecting end of the first load-bearing wall 200 and the second load-bearing wall 300 has a reinforcing bar structure 400 that protrudes directly and is arranged alternately. Since this type of reinforcing bar structure 400 is fixed by being bound or welded using extra reinforcing bars, many extra reinforcing bars must be used, which is disadvantageous in terms of cost and market competition. .

  In addition, traditionally, the first load-bearing wall 200 and the second load-bearing wall 300 are connected and fixed, usually using an extra reinforcing bar, and cemented with cement. A full load bearing wall is formed on the second load bearing wall 300. Although the extra reinforcing bars fix the first bearing wall 200 and the second bearing wall 300, in practice, this type of fixing method has no effect of increasing the resistance to the lateral stress of the bearing wall, and the construction structure is like an earthquake When faced with extreme stress, it is this articulated end that becomes the most vulnerable place of the bearing wall in the building structure, which cannot accept the stress and causes structurally irreparable damage. Become.

  Furthermore, since the entire structure of the conventional reinforcing bar structure 400 is too loose, it is not easy to fix with an extra reinforcing bar, and if the structure is complex, the cost of the reinforcing bar will increase. At the same time, if the overall structure of the reinforcing bar structure 400 is too disjointed, it is difficult to improve the hardness by the fixed interaction. Therefore, how to increase the area of interaction of the connecting structure in the precast bearing wall and how to increase the hardness between the connecting structures of the precast bearing wall has always been a problem for construction engineers.

  The present inventor submits the present invention, which is a rational and effective design to remedy the above-mentioned drawbacks through a combination of repeated research and operation of academic theory, in order to improve and solve the above-mentioned drawbacks.

  The main object of the present invention is to provide a precast bearing wall connection structure that can improve the interaction between the first bearing wall and the second bearing wall with a new steel structure.

  It is another object of the present invention to provide a precast bearing wall connection structure that can improve the hardness against the transverse stress in the bearing wall without increasing the cost of the reinforcing bar by the new reinforcing bar structure.

  It is another object of the present invention to provide a precast bearing wall connection structure that can improve the bond strength of the connecting end of the precast bearing wall and prevent the occurrence of structurally irreparable damage.

The first precast bearing wall,
Including a second precast bearing wall,
The first side end face of the first precast bearing wall includes a first U-shaped structural reinforcing bar protruding outward from the inside of the bearing wall, and the second side end face of the second precast bearing wall corresponding to the first precast bearing wall is A second U-shaped structural reinforcing bar protruding outward from the bearing wall, wherein the first U-shaped structural reinforcing bar and the second U-shaped structural reinforcing bar are arranged alternately, and the first U-shaped structural reinforcing bar and the second U-shaped structural reinforcing bar Character-shaped structural reinforcing bars are composed of upper horizontal reinforcing bars, lower horizontal reinforcing bars, and vertical reinforcing bars that connect horizontal reinforcing bars, and the upper and lower horizontal reinforcing bars are distributed in parallel in the vertical direction along the wall surface direction. A precast bearing wall connection structure.

  According to this precast bearing wall connection structure, the new steel structure can improve the interaction between the first bearing wall and the second bearing wall, and in the bearing wall without increasing the cost of the reinforcing bars. The hardness against the lateral stress can be improved, and further, the joint strength of the connecting end of the precast bearing wall can be improved to prevent structurally unrecoverable damage.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  As shown in FIG. 2, the precast bearing wall connecting structure 100 according to the present invention includes a first bearing wall 200 and a second bearing wall 300. The first side end surface 210 of the first load bearing wall 200 includes a first U-shaped structural reinforcing bar 410 protruding outward from the load bearing wall. The second side end surface 310 of the second load bearing wall 300 corresponding to the first load bearing wall 200 includes a second U-shaped structural reinforcing bar 430 protruding outward from the load bearing wall. Although the first U-shaped structural reinforcing bar 410 and the second U-shaped structural reinforcing bar 430 are arranged alternately, they may be arranged relative to each other and do not necessarily have to be arranged alternately. Staggered arrangement can increase the hardness of the articulated structure, but relative arrangement is easy to fix with extra reinforcing bars, so relative arrangement can increase convenience in actual construction it can. In addition, the fixing method includes screwing, welding, binding, or a method that can provide the same effect and a combination thereof. Further, the first U-shaped structural reinforcing bar 410 and the second U-shaped structural reinforcing bar 430 are composed of an upper horizontal reinforcing bar 470, a lower horizontal reinforcing bar 490, and a vertical reinforcing bar 480 connecting the horizontal reinforcing bars. The upper horizontal reinforcing bar 470 and the lower horizontal reinforcing bar 490 are distributed in parallel in the vertical direction along the wall surface direction. The first U-shaped structural reinforcing bar 410 and the second U-shaped structural reinforcing bar 430 may be arranged in a vertical staggered arrangement in addition to the parallel staggered arrangement, and the plane formed by the first U-shaped structural reinforcing bar 410 and the second U-shaped structural reinforcing bar 430. Since the plane formed by 430 is vertical, the strength to resist lateral stress can be increased. In the preferred embodiment, the plane formed by the first U-shaped structural reinforcing bar 410 and the second U-shaped structural reinforcing bar 430 is parallel to the wall surface, but not all are parallel to the wall surface. The upper horizontal reinforcing bar 470, the lower horizontal reinforcing bar 490 and the vertical reinforcing bar 480 are integrally formed, and a single reinforcing bar is bent into a U-shape, thereby expanding and increasing the horizontal interaction area and improving the building strength. Can be made.

Consists of reinforcing bars. A single U-shaped rebar can be assembled by using different reinforcing bars for each. The first U-shaped structural reinforcing bar 410 and the second U-shaped structural reinforcing bar 430 have the same number, type or size of reinforcing bars. In addition, different design demands and structural strengths can be accommodated by changing the number, type or size of the reinforcing bars and combining them.

  As shown in FIG. 2 b, the upper horizontal reinforcing bar 470 and the lower horizontal reinforcing bar 490 in the first bearing wall 200 and the second bearing wall 300 overlap with each other in the projection along the normal direction of the wall surface. Form a structure. The rectangular structure is quickly connected to the structure and fixed using an extra reinforcing bar, so that the first U-shaped structural reinforcing bar 410 and the second U-shaped structural reinforcing bar 430 are projected along the normal direction of the wall surface. They overlap each other and form a square or staggered rectangle with the longitudinal rebar 480. Further, the longitudinal reinforcing bars 480 of the first bearing wall 200 and the second bearing wall 300 are parallel to each other, but are not necessarily absolutely parallel.

  As shown in FIG. 2c, the first U-shaped structural reinforcing bar 410 and the second U-shaped structural reinforcing bar 430 are parallel to each other and alternately arranged. In a different embodiment, the first U-shaped structural reinforcing bar 410 and the second U-shaped structural reinforcing bar 430 may intersect each other to form an X shape.
