Detailed Description

The utility model is described in detail below with reference to the attached drawings and the specific embodiments:

1-2, the wavy pre-buried floor seam comprises a wavy partition plate 2, two wavy corner protection strips 1, a fixing assembly 4, an anchor bolt 3, a force transmission plate pin 5 and a plate pin sleeve 6, wherein the two corner protection strips are correspondingly provided with bolt holes, the top ends of the two corner protection strips are kept flush and tightly adhered and connected by the fixing assembly penetrating through the bolt holes, and the outer sides of the corner protection strips are fixed with anchor bolts at intervals; the upper end of the partition plate is fixed at the lower end of one corner protection strip, the lower half section of the partition plate is provided with rectangular openings at intervals, and a force transmission plate pin is inserted and fixed in the openings; the force transmission plate pin is a rectangular plate, two ends of the force transmission plate pin are respectively kept at two sides of the partition plate, and one end of the force transmission plate pin is sleeved with a plate pin sleeve.

The material of division board is cold rolled steel sheet, and the material of corner protection strip is Q235B's band steel, and the connected mode between division board and the corner protection strip is the welding.

The fixing component consists of a plastic bolt and a butterfly nut.

The force transmission plate pin is made of Q345B steel, welded and fixed with the opening of the partition plate, and the plate pin sleeve is made of ABS or HDPS.

The anchoring bolts are made of Q235C steel and are welded at the wave crests of the corner protection strips at intervals, and the other ends of the anchoring bolts of the same corner protection strip are welded on a thread reinforcing steel bar (7) with phi 18-phi 22.

The center-to-center spacing of the rectangular openings arranged at intervals is 500mm.

The length of the terrace seam is 2000mm, the height is 90-245mm, and the terrace seam is used for a terrace with the thickness of 100-250 mm for C25-C45 concrete pouring.

Example 1:

before pouring a small-scale concrete ground, placing wavy terrace joints at positions reserved for forming terrace expansion joints, and respectively welding anchor bolts on two sides of the wavy terrace joints to a phi 18 threaded steel bar so as to keep the integrity of the anchor bolts; and then pouring concrete is started, shrinkage is generated after the concrete on the two sides of the terrace seam is finally solidified, and the generated force breaks the plastic bolts in the fixing assembly, so that two wavy corner protection strips are separated by a certain distance to form cracks, and the cracks can extend downwards until the bottom of the concrete layer, and the automatic slotting of the expansion joint is completed.
