[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0018] like Figures 1-3The earthquake-resistant system of exposed concrete wall based on the tie principle shown includes structural column wall 1, inner wall 2, outer exposed concrete wall 3, longitudinal tie bars of the inner wall 4, transverse tie bars of the inner and outer walls 5, longitudinal tie bars of the outer wall 6, transverse support wall 7, and vertical dowel bars 8. The outer exposed concrete wall 3 is connected to the inner wall 2 through the transverse tie bars of the inner and outer walls 5 or the transverse support wall 7 to ensure overall earthquake resistance.
[0019] Specifically, refer to Figure 1 Structural column 1 is a reinforced concrete column located in the middle of interior wall 2. Interior wall 2 is a masonry wall constructed using masonry blocks. Before construction, interior wall 2 and exterior exposed concrete wall 3 should be pre-laid together. If their vertical modules do not match, a concrete curb can be installed at the bottom of interior wall 2 or a tie beam can be installed in the middle of interior wall 2 for adjustment. Interior wall 2 needs to be supported on the beams, slabs, or cantilever beams of each floor, and its self-weight is transferred layer by layer to the main concrete structure.
[0020] Reference Figure 1 The exterior exposed concrete wall 3 can be constructed using porous exposed concrete bricks and needs to be supported on the beams, slabs, or cantilever beams of each floor. Its self-weight is transferred to the main concrete structure layer by layer. Out-of-plane forces (including wind and seismic forces) are transferred to the interior wall 2 or the main concrete structure by the transverse tie bars 5 of the interior and exterior walls.
[0021] Reference Figure 1 The longitudinal tie bars 4 of the inner wall should be heavy-duty galvanized steel bars or steel bars with equivalent protective coating, with no less than 2 bars and a specification of not less than Φ6. They should be placed in the mortar joint of the inner wall 2 and arranged along the entire length of the inner wall 2. The ends should be anchored in the structural column wall 1 or the wall of the adjacent inner wall 2. They should be arranged at intervals of no more than 400mm in the wall height direction.
[0022] Reference Figure 1 The transverse tie bars 5 of the inner and outer walls are used when the distance d1 between the inner wall 2 and the outer fair-faced wall 3 is not greater than 300mm. The transverse tie bars 5 of the inner and outer walls should be heavy galvanized steel bars or steel bars with equivalent protective coatings. The steel bar specifications are not less than Φ6 and the horizontal spacing d2 is not greater than 500mm.
[0023] Reference Figure 1 The longitudinal tie bars 6 of the exterior wall should be made of heavily galvanized steel bars or steel bars with an equivalent protective coating. The quantity should be set according to the width of the exterior fair-faced wall 3, and the spacing should not be greater than 100mm. The steel bar specifications of the longitudinal tie bars 6 of the exterior wall should not be less than Φ6. They should be placed in the mortar joints of the exterior fair-faced wall 3 and arranged along the entire length of the exterior fair-faced wall 3. The spacing in the wall height direction should not be greater than 400mm.
[0024] Reference Figure 2 ,and Figure 1The difference is that the distance d1 between the inner wall 2 and the outer exposed wall 3 exceeds 300mm. The horizontal tie rod 5 of the inner and outer walls is changed to the horizontal support wall 7. The horizontal support wall 7 can be made of concrete or masonry structure. The spacing d3 is determined according to the design calculation. A structural column wall 1 needs to be set at the intersection of the horizontal support wall 7 and the inner wall 2.
[0025] Reference Figure 2 Vertical reinforcing bars 8 are installed in the horizontal support wall 7 and the outer fair-faced concrete wall 3. When installing, they must be installed at the corners and ends. Each fair-faced concrete porous brick of the outer fair-faced concrete wall 3 must have at least one vertical reinforcing bar 8 passing through it, and the vertical reinforcing bars 8 must be anchored in the main concrete structure. The anchorage length must meet the requirements of the specifications.
[0026] Reference Figure 3 The transverse tie bar 5 of the inner and outer walls includes a straight tie bar section 5-1 and a tie bar hook section 5-2. The length of the tie bar hook section 5-2 is not less than 10d, which is ten times the diameter of the transverse tie bar 5 of the inner and outer walls. The tie bar hook sections 5-2 located at both ends of the straight tie bar section 5-1 are welded to the longitudinal tie bar 4 of the inner wall and the longitudinal tie bar 6 of the outer wall, respectively.
[0027] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
