2)The outer impeller of casting concrete(Not shown in figure), thermal-insulation connecting piece is set on the outer impeller of concrete(Not shown in figure), And conserved;
3)After the completion of the outer impeller maintenance of concrete, it is placed in die station, insulating layer is placed on outer impeller(Not shown in figure), Thermal-insulation connecting piece penetrates insulating layer;Insulating layer is such as not required or insulating layer and outer impeller is not required, it is convenient to omit step 2)And step Rapid 3);
4)Steel framework is placed in die station;Horizontal reinforcement 3, vertical reinforcement 4 are fixed on steel framework;By the two end portions of horizontal reinforcement 3 It is not welded on the ala lateralis listrium of two columns 2, the upper end of vertical reinforcement 4 is welded on the crossbeam floor of end, vertical steel The bottom of muscle 4 is welded on 5 floor of junction steel plate seat;
5)The corresponding position per floor plate is provided with the reserved section of cast;Using two inner side flange plates as side mould two columns 2 it Between pour into a mould concrete, vibrate while pouring;The corresponding position of end transom bolt mounting hole should set installation bolt or The technology groove of nut, is easily installed bolt or nut;
6)Concrete curing is carried out after the completion of pouring.Pour and the reserved section of cast is left among the concrete seven to be formed, poured for scene Build.Steel framework is segmented and surrounds by prefabricated concrete block 7.
End crossbeam can also be arranged below, junction steel plate seat 5 is disposed over.
As shown in figure 5, after the prefabricated steel reinforced concrete shear wall structure of multilayer is transported to scene, pacified by the following method Dress:
1)Lower floor shear wall structure B is installed;Fixed with temporary support, the steel of the prefabricated steel reinforced concrete shear wall structure of multilayer is horizontal 1 both ends tee girder support 6 of beam and connecting plate 8 are attached with the lower flange of periphery girder steel 11 and web respectively, set L-shaped connector 9 It is attached respectively with the top flange of periphery girder steel 11 and the junction steel plate seat 5;
2)Each horizontal floor of layer in the prefabricated steel reinforced concrete shear wall structure of multilayer is installed, sets gradually the horizontal floor steel of each layer Muscle;
3)Pour into a mould the overlapping layer concrete and the reserved section of cast of each floor plates of lower floor shear wall structure B;
4)By the end crossbeam of the Interal fixation seat 5 of upper strata shear wall structure A lower ends and lower floor shear wall structure B upper ends with high-strength It is bolted, the junction steel plate seat is connected with periphery girder steel 11;
5)Setting horizontal distribution reinforcing bar in reserved section is poured in junction, pour junction pours reserved section;
6)The horizontal precast floor slab of story shear wall construction A is installed, sets gradually horizontal floor bar;
7)Pour into a mould Concrete Filled floor;
Upper strata shear wall structure A and lower floor shear wall structure B are installed;Repeat step 1)To step 7), until all layers Shear wall structure, which is respectively mounted, to be finished.
Compared with prior art, precast reinforced concrete shear wall structure can only be pre- using a depth of structural layer as one Unit processed, causes that jointing quantity is more, and construction efficiency is not high;Bone of the present invention by the use of built-in steel framework as load-bearing during construction Frame, realizes using multiple depth of structural layer as a prefabricated unit, greatly reduces the quantity of jointing, can carry significantly High construction efficiency.Periphery steel framework column using hot rolled H-shaped, easy to girder steel using being bolted entirely;Periphery steel framework column and shearing Wall thickness is identical, and bending bearing capacity is stronger outside the face of shear wall, is connected with girder steel more convenient.The web of periphery steel framework column It is coated on on the inside of the inner side edge of a wing and outer side wing edge in concrete, greatly reduces the area of anti-corrosion flame-proof finishing, save The expense of anticorrosive coating.The outside of the outer side wing edge of periphery steel framework column is outside concrete, easy to be connected with periphery girder steel. Precast reinforced concrete shear wall structure vertically connects generally use bar splicing or grout sleeve connection mode, this kind of connection side Formula is higher to the requirement on machining accuracy of prefabricated components, and site operation is difficult;Sleeve grouting is concealed work, and grouting quality is difficult to protect Card, and reinforcing steel bar connecting sleeve tube cost is higher.The present invention:1)Utilize upper section precast shear wall junction steel plate seat and the lower prefabricated shearing of section Wall periphery steel framework is connected by high-strength bolt, avoids the problem of Vertical bar connection;2)Precast shear wall and steel of the present invention Beam is connected by high-strength bolts, and upper section precast shear wall junction steel plate seat had not only played precast shear wall connection function up and down but also risen To with girder steel connection function, multi-purpose content, better economy.Due to steel construction high precision machining, connection mode of the present invention can be with Ensure site operation quality;Without concealed work, quality is easy to ensure the connection mode at the same time.Periphery steel framework of the present invention can play Load-bearing skeleton during installation, the connector being connected with last layer installation unit and periphery girder steel 11 at the same can with confined concrete, and With the common bearing load in armored concrete part, structural bearing capacity higher, anti-seismic performance is more preferable, can be adapted for high earthquake intensity Area.
