The elastic plate 2 is a foamed aluminum plate which has low density and has stronger high impact absorption capacity and damping and shock absorption performance. In addition, the foamed aluminum plate is high-temperature resistant, corrosion resistant, high in weather resistance, sound-proof and noise-reducing. Concrete base 3 sets up on ground floor 9, has still laid waterproof roll material layer 8 between concrete base 3 and the ground floor 9, is provided with carborundum terrace layer 4 on concrete base 3's the top surface. The waterproof roll layer 8 is formed by a BAC double-sided self-adhesive waterproof roll which has the property of bonding with cement paste. The high molecular polymer in the coiled material rubber material and cement hydrate form an interpenetrating network structure, the cement can flow and permeate before initial setting, the setting strength is increased day by day, and the binding power is enhanced. When the waterproof roll material layer 8 is locally damaged, water is limited to a small range and does not flow in a channeling way.
Referring to fig. 1 and 3, inside the concrete base 3Near the wall column 1Is provided withThe first steel wire mesh 31 is arranged inside the carborundum floor layer 4Near the wall column 1A second steel wire mesh 41 is arranged, and the first steel wire mesh 31 and the second steel wire mesh 41 are parallel to each other. The first steel wire mesh 31 has a total length of 1 m and a total width of 1 m. The first steel wire mesh 31 is symmetrically arranged about the wall stud 1. First wire net 31 and second wire net 41 make carborundum terrace layer 4 and concrete-based layer 3 be close to the joint strength of wall post 1 department higher, and the wholeness is better, can prevent that carborundum terrace layer 4 and concrete-based layer 3 of wall post 1 department from taking place the phenomenon of rupture. In addition, first wire net 31 and second wire net 41 all can adopt the galvanized steel wire net, and the galvanized steel wire net can play damp-proof heat retaining effect, can obviously reduce expend with heat and contract with cold to the destruction of concrete terrace, and on the other hand the toughness of galvanized steel wire net is still stronger than the same specification steel wire, can effectively increase the concrete strength, further reduces concrete terrace fracture risk.
Referring to fig. 1 and 3, in order to facilitate connection and fixation of the first steel wire mesh 31 and the second steel wire mesh 41, a plurality of hollow sleeves 32 are welded at connection nodes on opposite side surfaces of the first steel wire mesh 31 and the second steel wire mesh 41, the sleeves 32 are made of stainless steel and are cylindrical, correspondingly, convex columns 42 which are in clamping fit with the sleeves 32 are welded on the bottom surface of the second steel wire mesh 41, the convex columns 42 are made of stainless steel, and the outer diameters of the convex columns 42 are equal to the inner diameter of the sleeves 32. In order to facilitate workers to insert the convex column 42 into the sleeve 32 quickly in a construction site, one end of the convex column 42, which is far away from the second steel wire mesh 41, is connected with a guide part 421 with a semicircular section, and the guide part 421 and the convex column 42 are integrally formed. The sleeve 32, the first steel wire mesh 31, the convex column 42 and the second steel wire mesh 41 are all pre-processed in a factory and then directly transported to a construction site for laying. When the steel wire mesh is laid, the first steel wire mesh 31 is firstly laid in the concrete base layer 3, and the upper half part of the sleeve 32 extends out of the concrete base layer 3. After the concrete base layer 3 is solidified, the convex columns 42 are sequentially inserted in alignment with the sleeve 32 to complete installation of the second steel wire mesh 41, and then the carborundum terrace layer 4 is paved.
Referring to fig. 1 and 3, in a humid and cold weather, water in the concrete gap forms fatigue stress under the combined action of ice expansion pressure and osmotic pressure under the action of alternate dry and wet and freeze-thaw cycles, so that the concrete is degraded from the outside to the inside. After multiple freeze-thaw cycles, the concrete terrace is prone to cracking. In order to prevent the joint of the sleeve 32 and the concrete base layer 3 from cracking due to freeze-thaw cycle, the outer side surface of the sleeve 32 close to one end of the first steel wire mesh 31 is sleeved with a water-swelling water stop strip 6 with an annular cross section. The first water-swelling sealing rod 6 is composed of polymer inorganic water-swelling materials and rubber, and can absorb water and expand in volume when meeting water, so that a gap is blocked, a waterproof plastic colloid is formed, and the sealing property of connection between the sleeve 32 and the concrete base layer 3 is improved. The bottom surface of the second steel wire mesh 41 is bonded with a second water-swelling water stop strip 7 with an annular cross section, the second water-swelling water stop strip 7 is coaxial with the convex column 42, and the inner diameter of the second water-swelling water stop strip 7 is equal to the outer diameter of the sleeve 32. After the convex column 42 is sequentially aligned with the sleeve 32 and inserted, the top end of the sleeve 32 is correspondingly clamped into the second water-swelling water stop strip 7, so that the tightness of connection between the second steel wire mesh 41 and the carborundum terrace layer 4 is improved, and the terrace is prevented from cracking due to water leakage.
Referring to fig. 1 and 2, the concrete itself has the characteristic of expanding with heat and contracting with cold according to the seasonal temperature, and when the concrete is subjected to telescopic activities, the concrete is extruded towards the wall column 1 when reaching the side of the wall column 1. In order to make the terrace difficult to crack, a rubber pad 5 is bonded on the side surface of the elastic plate 2 far away from the wall column 1, and the rubber pad 5 is positioned between the wall column 1 and the concrete base layer 3. Because the rubber pad 5 is made of rubber material, the elasticity of the rubber pad 5 is reduced under the oxidation action after the use time is long, and an elastic device is arranged in the rubber pad 5. The elastic device comprises a plurality of cavities 51 arranged in a rectangular array in the rubber pad 5 and springs 52, wherein the springs 52 are arranged in the cavities 51, and the elastic direction of the springs 52 is consistent with the radial direction of the wall column 1. The cavity 51 enables the interior of the rubber pad 5 to be in a partially hollow state, so that the flexibility of the rubber pad 5 is increased; because the rubber pad 5 is made of rubber, after long-term use, under the oxidation action, the elasticity of the rubber pad 5 is reduced, and the cooperation of the spring 52 and the cavity 51 ensures that the rubber pad 5 keeps lasting elasticity, thereby prolonging the service life of the rubber pad 5; and when the concrete base layer 3 extrudes the rubber pad 5, the spring 52 is compressed, a part of energy is converted into elastic potential energy, a certain buffering effect is achieved, and the concrete base layer 3 is not easy to crack.
The implementation principle of the embodiment is as follows: firstly, a waterproof coil material layer 8 is laid above a ground layer 9, then an elastic plate 2 and a rubber pad 5 are sequentially fixed on the periphery of a wall column 1, and cement mortar is coated to form a concrete base layer 3.
