As a further improvement of the utility model, when assembling, the left wall is fixed, and the right wall is moved horizontally horizontally, so that the row-shaped tooth-shaped steel members are inserted and locked in the concave holes of the left wall.

As a further improvement of the utility model, the concave hole is reserved at the right end of the wall when the left wall is prefabricated, and the tooth-shaped steel member is embedded in the left end of the right wall when the right wall is prefabricated.

As a further improvement of the utility model, the inner width of the concave hole is greater than the width of the end lock step, and the tooth unit includes a groove in the middle and hook-shaped protrusions on both sides. After the docking is completed, the lock The hook-shaped protrusion abuts against the inside of the concave hole.

As a further improvement of the utility model, the hook-shaped projections of the tooth-shaped steel members are trapezoidal projections.

As a further improvement of the utility model, the row-shaped tooth-shaped steel members are arranged in two parallel rows.

The beneficial effects of the utility model are as follows:

The vertical seam connection structure of the prefabricated shear wall of the utility model is engaged and connected by the pre-embedded section steel on both sides in the vertical direction. The construction process is simplified, the construction difficulty is reduced, the dimensional accuracy of the components is high, it is easy to control, the on-site sanitation conditions are improved, the production efficiency is improved, and it can be mass-produced.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The connection structure of the prefabricated wallboard row-shaped tooth-shaped steel of the utility model is shown in Figure 1, the left prefabricated assembled wall (hereinafter referred to as the left wall 1) and the right prefabricated assembled wall (hereinafter referred to as the right side) Side wall body 2). The right end of the left wall body 1 is reserved with recessed holes at intervals from top to bottom, and the ends of the recessed holes form two locking steps. The left end of the right wall 2 is pre-embedded with an integral row-shaped tooth-shaped steel member 3. The row-shaped tooth-shaped steel member 3 includes several tooth units. Arranged at intervals, the end of the tooth unit is in the shape of a lock hook, and the plane where the concave holes and the row-shaped tooth-shaped steel members 3 are located is parallel to the plane of the wall. The facade structure before the left and right two walls are docked is shown in Figure 1, where the section structure along the A-A direction in Figure 1 is shown in Figure 2, and the section structure along the B-B direction in Figure 1 is shown in Figure 3, the left and right sides The top view structure of the piece wall butt joint is shown in Figure 6.
