An expansion joint material, especially an expansion joint material for a retaining wall.

Please refer to Figure 1. At present, there are a large number of retaining walls 2 stacked with retaining blocks on the hillside next to the road, and a retractable styrofoam is placed between each retaining wall 2 The joint material 1 is provided for each retaining wall 2 to have a changing space under the pressure of thermal expansion and contraction.

In order to make each expansion joint material 1 impervious to water, a waterproof layer will be added on the top of each expansion joint material 1 and on both sides. Please refer to Figures 2 and 3, in order to increase the waterproof layer. In general, a part of the top and both sides of each expansion joint material 1 will be dug out to form a filling space 11, and then a silicon waterproof coating 12 will be filled into each filling space 11. After each of the waterproof coatings 12 is dried, a waterproof layer is formed, although it can achieve the effect of preventing water seepage.

However, in the actual construction of each expansion joint material 1, a part of the upper part of each expansion joint material 1 and on both sides must be dug out as each filling space 11, in each filling space 11 Each of the waterproof coatings 12 of Silicone will be filled separately and then dried up, which is troublesome and time-consuming in construction.

Therefore, each of the above-mentioned expansion joint materials 1 is dug out each filling space 11 at the top and on both sides, and then each filling space 11 is filled with each waterproof coating 12 respectively. In actual construction, This will increase the trouble of the construction procedure and consume the construction time, and it is difficult to meet the requirements of the retaining wall 2.

To solve the problem of improving the construction of each expansion joint material between the existing retaining walls, the filling space above and on both sides of each expansion joint material must be dug out, and then each expansion joint material must be dug out. One should fill the space to fill each of the waterproof coatings separately, which will increase the trouble of construction procedures and time-consuming problems. This creation provides an expansion joint material for retaining walls. The expansion joint material is formed by integrally extruding the hard plastic body and the soft plastic system of two different materials to increase the combination between the hard plastic body and the soft plastic body The expansion joint material is fixed on the upper side of each retaining wall and on both sides, so that the expansion joint material is fast and convenient in production, which is the main creative purpose.

In order to achieve the purpose of the aforementioned creation, the technical solution adopted in this creation is to provide a retaining wall expansion joint material, which is used to provide the expansion joint material for the gaps between the retaining walls. The expansion joint material includes A rigid plastic body and a soft plastic body formed by integral extrusion. Wherein, the hard plastic body is elongated in the longitudinal direction and its cross section is a rectangular frame, and one end of the hard plastic body is extended with a coupling recess. The soft plastic body is elongated in the longitudinal direction and its cross-section is a rectangular entity. The soft plastic body is provided with a coupling convex portion facing the coupling concave portion and engaging with the coupling concave portion.

Furthermore, the coupling recess has two corresponding convex stoppers extending from one end of the hard plastic body, a groove sandwiched between the convex stoppers, and a groove between the convex stoppers and The groove intersecting the opening.

Furthermore, the coupling convex portion has an inverted convex block combined with the groove and the opening to increase the coupling between the coupling convex portion and the coupling concave portion.

With this creation, the retaining wall expansion joint material has the following beneficial effects:
