Detailed Description
The invention is further described below with reference to the accompanying drawings and specific embodiments.
A production and construction method of a lap joint prefabricated wall body, for example, a wall body with the height of 2700mm, the width of 4000mm and the thickness of 200mm is prefabricated according to the following steps:
A. the wall body mold frame 1 is arranged, the wall body mold frame 1 is formed by surrounding four channel steel, the four channel steel are M1, M2, M3 and M4, M1 is the top of the wall body mold frame 1, M2 is the bottom of the wall body mold frame 1, M3 is the left side of the wall body mold frame 1, M4 is the right side of the wall body mold frame 1, and a mold hole I5 is formed in the middle of the M1.
B. A bottom die 3 is installed in the middle of the M2, the bottom die 3 is a rectangular frame structure formed by welding steel pipes and channel steel, wherein the steel pipes are used as bottom edges 33 of the bottom die 3 and are connected with M2 through bolts, two side edges 32 and a top edge 32 of the bottom die 3 are respectively formed by welding channel steel, and the length of the bottom edge 33 of the bottom die 3 is slightly larger than that of the top edge 31; rubber slab 4 is installed through the bolt respectively in the outside of topside 31 and two sides 32 of bottom mould 3, and the width of rubber slab 4 equals with the thickness of prefabricated wall body, reserves a plurality of openings 41 that can guarantee that the reinforcing bar passes on two long edges of every rubber slab 4 respectively.
C. A second die hole 6 with the diameter of 100mm is reserved at the position, corresponding to the first die hole 5, of the top edge 31 of the bottom die 3, and a corresponding circular hole is reserved at the position, corresponding to the second die hole 6, of the rubber plate 4 installed on the top edge 31.
D. Carry out the reinforcement in wall body mould frame 1 inside, during the reinforcement moreover, the opening 41 on rubber slab 4 is passed in proper order to the reinforcing bar around the bottom mould 3, and opening 41 both can the position of fixed reinforcing bar, can also guarantee that the protective layer of reinforcing bar is not destroyed.
