Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses parapet prevents ftractureing flood structure. Referring to fig. 1, the parapet anti-cracking flashing structure includes a roof layer 1, a parapet 2 installed on the roof layer 1, and a shielding assembly 3 installed on the parapet 2. It can shelter from the rainwater to shelter from subassembly 3, reduces the rainwater and directly erodees with roof layer handing-over department on the parapet, has reduced the long-term erosion and corrosion that receives the rainwater of handing-over department between parapet and the roof layer, and the waterproof layer produces the possibility of crack infiltration easily.

Referring to fig. 1, a roof layer 1 is a reinforced concrete layer as a whole, and the roof layer 1 is located on the top of a building. The parapet wall 2 comprises a base wall body 21 and a leveling layer 22 laid on the base wall body 21. The parapet 2 is wholly a cuboid with a rectangular section, the height of the parapet 2 is 1-1.5m, and the parapet 2 is located at the edge of the roof layer 1 to prevent residents from falling to the ground from the roof carelessly. The base layer wall body 21 is filled with the steel reinforcement cage 211, the steel reinforcement cage 211 is a cuboid mesh structure formed by steel reinforcement bars in a staggered mode, the long edge of the steel reinforcement cage 211 is perpendicular to the plane of the roof layer 1, and concrete is poured on the steel reinforcement cage 211 to form the base layer wall body 21. The base layer wall 21 formed by the reinforcement cage 211 and the concrete has higher strength, residents can be effectively protected, and the residents are prevented from being injured due to collapse of the base layer wall 21; meanwhile, the service time of the parapet wall 2 can be prolonged, and the maintenance frequency is reduced. The screed-coat 22 can be for cement mortar layer or fine stone concrete layer, selects the former here, and screed-coat 22 is laid and can be filled and led up unevenness's basic unit's wall body 21 surface on basic unit's wall body 21, can also restore basic unit's wall body 21 surperficial tiny crackle simultaneously, the convenient further construction to the wall body. The part, close to the joint of the parapet wall 2 and the roof layer 1, of the leveling layer 22 is thickened to form a slope 221, the section of the slope 221 is a right-angled triangle, one end of the inclined edge of the right-angled triangle is connected with the parapet wall 2, and the other end of the inclined edge of the right-angled triangle is connected with the roof layer 1. The slope 221 can effectively prevent rainwater from washing the joint of the parapet wall 2 and the roof layer 1, and reduces the possibility of rainwater erosion at the joint of the parapet wall 2 and the roof layer 1.

Referring to fig. 1 and 2, in order to reduce the possibility that the temperature difference between the parapet wall 2 and the roof layer 1 is too large due to the temperature change of the roof layer 1 driven by the indoor temperature change, and further the crack is generated at the joint of the parapet wall 2 and the roof layer 1, the leveling layer 22 is provided with the heat insulation layer 23. The heat preservation layer 23 is an EPS heat preservation plate or a polyurethane heat preservation plate, and the heat preservation layer 23 is bonded with the leveling layer 22 through an adhesive. In order to prevent rainwater from penetrating into the inner side of the house wall from the roof layer 1 and the parapet wall 2, a waterproof layer 24 is laid on the heat insulation layer 23, the waterproof layer 24 can be asphalt waterproof coiled material or synthetic rubber waterproof coiled material, and the waterproof layer 24 extends from the roof layer 1 to the parapet wall 2. In order to reduce rainwater and directly wash the waterproof layer 24, a protective layer 25 is laid outside the waterproof layer 24, and the protective layer 25 can be epoxy resin modified cement mortar or polyurethane modified cement mortar.

Referring to fig. 1 and 2, in order to fix the heat-insulating layer 23 and the waterproof layer 24 to the parapet wall 2, a capping ring beam 26 is provided on the parapet wall 2 at a side away from the roof layer 1, and the capping ring beam 26 is formed by pouring concrete. The two sides of one side of the ring beam 26 far away from the roof layer 1 extend in opposite directions to form bulges 261, and the bulges 261 can shield the walls on the two sides of the parapet wall 2, so that the erosion of rainwater to the two sides of the parapet wall 2 is reduced. Because the waterproof layer 24 and the protective layer 25 do not cover the outer side of the parapet wall 2, in order to reduce the phenomenon that rainwater on the top ring beam 26 drips on the outer side of the parapet wall 2 in the falling process to corrode the wall body, the top ring beam 26 is obliquely arranged towards the direction of the roof layer 1 while being far away from the roof layer 1, the rainwater on the top ring beam 26 is drained, and the water flows into a roof drainage system through the roof layer 1 to be evacuated.

Referring to fig. 1 and 2, the barrier assembly 3 includes a barrier 31 and a fixing member 32. The baffle 31 is a rectangular plate, the baffle 31 is provided with a folded edge 311, and the folded edge 311 is provided with a plurality of holes. The fixing member 32 may be an expansion bolt or a chemical bolt, and the fixing member 32 may pass through a hole on the flange 311 to fix the baffle 31 on the parapet wall 2 near the slope 221, and the baffle 31 is disposed to be inclined toward the roof layer 1. The baffle 31 can play a role in shielding the slope 221, so that the erosion of rainwater to the slope 221 is reduced, the erosion of rainwater at the joint between the parapet wall 2 and the roof layer 1 for a long time is reduced, and the possibility that the waterproof layer 24 is easy to crack and seep water is reduced. In order to reduce the possibility of rainwater seeping into the parapet wall 2 from the joint of the baffle 31 and the parapet wall 2, the folded edge 311 is adhered and covered with a rubber strip 312, and the rubber strip 312 can play a role of sealing at the folded edge 311.

The implementation principle of parapet anti-cracking flooding structure of the embodiment of the application is as follows: the slope 221 at the interface between the parapet wall 2 and the roof layer 1 can reduce the erosion of rain water to the interface when it rains; baffle 31 on parapet 2 can shelter from slope 221, prevents that the rainwater from scouring away handing-over department, has reduced the long-term erosion and corrosion that receives the rainwater of handing-over department between parapet and the roof layer, and the waterproof layer produces the possibility of crack infiltration easily.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
