Detailed Description

The following provides a more detailed description of the present invention, with reference to the accompanying drawings.

The utility model provides a structure constructional column, the anti-cracking structure is connected with the infilled wall in shear force wall, as shown in figure 1, the terminal surface of constructional column 1 and shear force wall 2 all is provided with reservation recess 5, pre-buried drawknot muscle 3 transversely stretches into from reservation recess 5 with inside bar connection, reservation recess 5 is for along the rectangular notch of terminal surface strip, pre-buried drawknot muscle 3 is evenly arranged downwards in reservation recess 5, every shear force wall 2 and the terminal surface of constructional column 1 all are provided with the same reservation recess 5 of quantity.

Each end face of the shear wall 2 and the construction column 1 will be connected to the filler wall 4 by an adhesive layer 6. The shear walls 2 and the constructional columns 1 are made of reinforced concrete because they are required to bear the entire weight of the building and the required load-bearing capacity is high, while the infill walls 4 are made of bricks and concrete which have a low structural strength but a low cost because they bear a low overall pressure.

As shown in fig. 2, 3 and 4, two prepared grooves 5 are provided on each end surface of the constructional column 1 and the shear wall 2, and the prepared grooves 5 are rectangular. The connection parts of the constructional column 1, the shear wall 2 and the filler wall 4 are connected by bonding mortar, the reserved groove 5 is filled with the bonding mortar to form a protruding part of a bonding layer 6, and a contact part is formed at the part in contact with the end face of the filler wall 4. When the constructional column 1 and the shear wall 2 will take place the dislocation because of various external force factors with infilled wall 4, the rectangle bulge that the bonding mortar formed firmly pins with reservation recess 5, and infilled wall 4 is piled up by the fragment of brick and forms, and the terminal surface is coarse, and the contact site that the bonding mortar formed is strong with infilled wall 4's cohesiveness, be difficult for droing, the external dislocation force that causes it has effectively been resisted through the pulling force of bonding formation of tie coat 6 to infilled wall 4 and the mortise and tenon structure that forms 5 through reservation recess to avoided the wall body of two kinds of different materials to take place the dislocation, produce the fracture in the junction.

When constructional column 1 and shear force wall 2 and infilled wall 4 stretch to two not equidirectional when respectively because external force, because pre-buried drawknot muscle material is firm, ductility is weak for constructional column 1 and shear force wall 2 become a whole with infilled wall 4 almost, and difficult consequently production fracture in the junction.

The constructional column 1 and the shear wall 2 are frames with steel bars built firstly, then the periphery of the constructional column 1 and the shear wall 2 is framed by the templates, the pre-buried tie bars 3 are placed, the end faces of the constructional column 1 and the shear wall 2 are all provided with the reserved grooves 5 and the pre-buried tie bars 3 are placed through the specific templates, and concrete can be directly poured after the pre-buried tie bars are placed.

Because the pre-buried tie bars 3 are too short, a welder will weld a section of extension bar before beginning to build a brick wall, and then begin to build the filler wall 4 directly next to the end faces of the constructional column 1 and the shear wall 2.

The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the scope of the present invention.
