[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0022] See also Figure 1 The utility model provides a waterproof flashing node structure for roof parapet wall plain concrete, comprising:
[0023] Floor 100;
[0024] The arch 200 is provided below the end of the floor slab 100;
[0025] A guardrail 300 is disposed above the end of the floor 100 corresponding to the position of the arch 200, a casting space is formed between the guardrail 300 and the floor 100, and one end of the guardrail 300 is connected to the arch 200, and the other end is disposed on the floor 100; and,
[0026] The waterproofing coiled material 400 is laid flat on the surface of the floor slab 100, and its end portion extends into the casting space.
[0027] In this embodiment, the waterproof membrane 400 is extended into the casting space formed by the guardrail 300 and the floor slab 100, and the guardrail 300 is pressed on the waterproof membrane 400, which can not only prevent the waterproof membrane 400 from falling off, but also improve the waterproof function at the node, thereby extending the service life of the waterproof membrane 400.
[0028] The application of this application in engineering is that the conventional roof flashing structure is a parapet decoration method after the roll material is turned up 250mm high, resulting in the inability to realize the design intention of the fair-faced concrete parapet waterproof flashing structure area of the roof; in order to realize the design intention, it is planned to move the roof parapet waterproof flashing structure inward, and then pour the roof handrail parapet fair-faced concrete.
[0029] In one embodiment, see Figure 1 A boss 101 is provided on the floor 100 , an inner concave surface which cooperates with the boss 101 is provided on the guardrail 300 , and a portion of the waterproof membrane 400 extending into the casting space is turned up and attached to the boss 101 .
[0030] This embodiment is configured such that the waterproofing membrane 400 is folded over the boss 101, which increases the inflection point at the connection and further improves the waterproofing effect at the node. After the guardrail 300 is installed, it is directly pressed on the waterproofing membrane 400, which improves the stability of the waterproofing membrane 400.
[0031] In one embodiment, see Figure 2 At least one integrally formed ridge 102 is provided on the surface of the boss 101 facing the guardrail 300 , and the ridge 102 extends in a straight line from the end of the boss 101 away from the floor 100 to the upper surface of the floor 100 .
[0032] This embodiment is configured such that when the guardrail 300 is installed, a groove that matches the convex rib 102 is correspondingly provided on the guardrail 300. Through the provision of the convex rib 102, the guardrail 300 can be pre-positioned during installation, thereby reducing the difficulty of subsequent positioning and maintenance.
[0033] In one embodiment, the boss 101 is upright or inclined toward the casting space.
[0034] In one embodiment, see Figure 2 and Figure 3 The top surface of the boss 101 has a convex edge 103 arranged in the direction of the guardrail 300 , the convex edge 103 is in an L-shaped structure, and the protruding distance of the convex edge 103 is greater than the thickness of the waterproof membrane 400 .
[0035] This embodiment is configured such that, through the configuration of the convex edge 103, when laying the waterproof membrane 400, the end of the waterproof membrane 400 is clamped in the convex edge 103, which can prevent the waterproof membrane 400 from being dislocated before the guardrail 300 is installed; preferably, the convex edge 103 can also be configured to be movable.
[0036] In one embodiment, a reinforced steel is provided in the arch 200. This arrangement of the embodiment can improve the structural strength of the arch 200 and enhance the overall stability of the node.
