Detailed Description
The utility model discloses a core lies in providing a split bolt hole antiseep shear force wall, can prevent to cause the seepage because of the fracture appears in the mortar shutoff.
In order to make those skilled in the art better understand the technical solution of the present invention, the anti-leakage shear wall with split bolt holes of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, which is a cross-sectional view of the anti-leakage shear wall with split bolt holes provided by the present invention, wherein the shear wall includes a wall body 1, a split bolt hole 2 is provided on the wall body 1, the split bolt hole 2 is a through hole formed by a split bolt of a positioning template when the shear wall is poured, the left side of the wall body 1 shown in fig. 1 represents an outer surface, the right side represents an inner surface, an elastically deformable plugging cork 3 is inserted in the outer end of the split bolt hole 2, that is, the elastically deformable plugging cork 3 is inserted in the left end of the split bolt hole 2, the plugging cork 3 is extruded by external force and inserted into the split bolt hole 2, the plugging cork 3 generates elastic deformation, the plugging cork 3 keeps interference fit with the split bolt hole 2, and the plugging cork 3 keeps relatively fixed fit with the split bolt hole 2 by friction force; filling foaming agent in the inner cavity of the split screw hole 2, filling the inner cavity of the split screw hole 2 through the foaming agent, playing a sealing effect to a certain extent, and adopting polyurethane foaming agent and the like.
Because the utility model discloses a but elastic deformation's shutoff cork realizes the sealed of split screw outer end, and the shutoff cork all the time with keep the interference seal fit to split screw 2, sealed for the mortar, even receive for a long time blowing and drenching the condition that also is difficult for appearing the fracture, play better sealed and antiseep effect.
On the basis of the scheme, the plugging soft plug 3 in the utility model is in a cone frustum shape, as shown in fig. 2A and fig. 2B, which are respectively a front view and a side view of the plugging soft plug 3; the cross section of the plugging soft plug 3 is circular, the diameters of the sections of the plugging soft plug 3 in the length direction are different, and the side surface is a conical surface; sleeving a sleeve outside the split bolt, taking out the split bolt after pouring, remaining the sleeve in the wall to form a split screw hole 2, and inserting one end of the plugging soft plug 3 with a smaller outer diameter into the sleeve in the split screw hole 2; the length of the sleeve pipe is equal to the thickness of the wall body 1, the sleeve pipe is of a cylindrical structure, and as the plugging soft plug 3 is in a cone frustum shape, the larger the length of the plugging soft plug 3 extending into the counter-pulling screw hole 2 is, the larger the deformation degree of the plugging soft plug 3 is, the tighter the plugging soft plug 3 is in contact with the counter-pulling screw hole 2, and the better the sealing effect is. For columniform structure, the utility model discloses an adopt soft stopper 3 of shutoff of circular cone frustum shape to realize inseparabler sealed effect.
