Right side wall be fitted on the madial wall of steel pipe 3, the left side wall of lower ear plate 6 is fitted on the lateral wall of lower steel pipe 4, in this way on
Otic placode 5 and lower ear plate 6 and the connection of upper steel pipe 3 and lower steel pipe 4 are reliable, further improve what steel pipe 3 was connect with lower steel pipe 4
Reliability.
In addition, in the present embodiment, as a preferred embodiment, as shown in figure 5, the bottom face of above-mentioned upper steel pipe 3 with
The bottom face of upper shear wall 1 is concordant, after upper shear wall 1 and lower shear wall 2 connect, the lower face of upper steel pipe 3 and upper shear wall
1, the connecting sewing between lower shear wall 2 keeps concordant.
When construction, corresponding hardness, the upper ear plate 5 of intensity and lower ear plate 6 are had according to building requirements selection first, and will be upper
Otic placode 5 and lower ear plate 6 are welded in rigid pipe 3 and lower steel pipe 4, then prefabricated upper shear wall 1 and band with upper rigid pipe 3
The lower shear wall 2 for having lower steel pipe 3, when construction site is assembled, lower shear wall 2 fixed first makes lower steel pipe 4 that lower ear plate to be housed
6 one end upward, then suspends upper shear wall 1 in midair, makes the madial wall in upper 3 left side of rigid pipe of the lateral wall alignment in 4 left side of lower steel pipe simultaneously
Shear wall 1 on falls downward, until the bottom face of upper shear wall 1 is bonded with the top end face of lower shear wall 2, as shown in fig. 7, this
When, the left side wall of upper shear wall 1 and the left side wall of lower shear wall 2 are in the state being staggered, and lower ear plate 6 is moved to positioned at upper ear plate
At 5 top position, then, upper shear wall 1 is pushed to the left, until the left side of the left side wall and lower shear wall 2 of upper shear wall 1
Wall keeps concordant, as shown in figure 8, at this point, the orthographic projection of upper ear plate 5 and lower ear plate 6 in the horizontal plane is with the part overlapped,
Finally, the concrete perfusion 7 out of the top of upper rigid pipe 3 upwards rigid pipe 3 and lower steel pipe 4 completes after waiting for concrete seven solidification
The connection of upper shear wall 1 and lower shear wall 2.
The present embodiment is by upper ear plate 5 and the upper steel pipe 3 of the connection of lower ear plate 6 and lower steel pipe 4, to complete prefabricated steel pipe shearing
The connection of wall, when connection, upper shear wall 1 can set aside to 2 top end face of lower shear wall, and upper shear wall 1 is no longer on suspended state, on
Shear wall 1 and lower shear wall 2 are easy to connect, also, the connection structure does not need live formwork supporting plate, can 3 He of steel pipe directly up
