DETAILED DESCRIPTION
[0016] The utility model will be described in detail in combination with the drawings as follows:
[0017] As Figure 1 Shown in one kind of assembly type floor component with roof pipe well, including prefabricated reinforced concrete prefabricated floor 1 and pipe well protection piece 2;The upper edge of the left and right side edges of the prefabricated floor 1 is provided with a notch to form a post-poured protruding edge 11, and the left and right sides of the prefabricated floor 1 are also provided with a stirrup 12 extending into the notch;The front and rear sides of the prefabricated floor 1 are also provided with external reinforcement 18;
[0018] The prefabricated floor slab 1 is provided with a pipe well passage 13, and the periphery of the pipe well passage 13 is provided with a limiting protruding edge 14, which is square; a plurality of concave key grooves 15 are arranged on the top surface of the prefabricated floor slab 1, and the top surface of the prefabricated floor slab 1 and the outer side surface of the protruding edge are paved with waterproof material 16; wherein the front and rear edges of the waterproof material 16 extend out of the front and rear edges of the prefabricated floor slab 1, the left and right edges of the waterproof material 16 extend into the gap, and the waterproof material 16 in the key groove 15 area is tightly attached to the surface of the key groove 15;
[0019] A concrete protective layer 17 is further arranged on the surface of the waterproof material 16 on the surface of the prefabricated floor slab 1 and the outer side surface of the protruding edge.
[0020] The pipe well protection member 2 is a reinforced concrete structure, which is formed by four side plates 21 and a top plate 22, wherein the four wall surfaces are provided with ventilation openings 23, and the top plate 22 is provided with an extended lifting steel bar 24; the pipe well protection member 2 is sleeved on the periphery of the limiting protruding edge 14.
[0021] The core of the utility model mainly lies in two points, first, the waterproof layer (waterproof material) and the concrete protective layer are laid when the prefabricated floor slab is processed in the prefabricated factory; and the concrete protective layer covers the limiting protruding edge (14), which solves the situation that the construction of the dark corner is not easy and leakage is prone to occur in the traditional construction process.
[0022] In the utility model, the waterproof layer is laid in the prefabricated factory, so that the process of consuming the construction period is flowed to the prefabricated factory link in advance, the effect of slow work and fine work is guaranteed, and the waterproof construction of the dark corner between the limiting protruding edge 14 and the floor slab is not prone to leakage. In addition, the structure formed by the original wall is made into an integrated pipe well protection member 2, the four side plates 21 and the top plate 22 involved are integrally formed, the waterproof effect is relatively ideal, the waterproof effect is further improved by coating waterproof paint when necessary, and the pipe well protection member is sleeved on the periphery of the limiting protruding edge, and does not affect the waterproof between the limiting protruding edge and the floor slab.
[0023] As for the waterproof treatment of the connecting part of the adjacent prefabricated floor slab component, two schemes are designed according to different positions here, generally, the front and rear sides of the prefabricated floor slab 1 are lapped on the main beam, the main beam is provided with an upward extending steel bar, the outward extending steel bar in the main beam and the outward extending steel bar of the prefabricated floor slab are bound and casted with concrete, so that the reliability of the connection between the prefabricated floor slab and the main beam can be guaranteed, then the waterproof material is additionally prepared to extend the front and rear edges of the waterproof material 16 out of the prefabricated floor slab 1, and the waterproof material is integrally formed by heat molding to realize the integral connection of the waterproof material in the area (as shown in the Figure 3
[0024] AsFigure 2 As shown, similarly, the stirrups on the left and right sides of the prefabricated floor slab 1 only need to consider placing the steel cage Figure 2 The two adjacent prefabricated floor slabs are connected to form an integral body by binding, and then concrete is cast, and the left and right edges of the waterproof material 16 are extended into the part of the gap and integrally formed by additional waterproof material heat molding.
[0025] The above completes the integrated layout of the waterproof material, and finally a layer of concrete is cast at the joint, flush with the concrete cover 17.
[0026] The key groove 15 is square and arranged in a rectangular array, the distance between any two adjacent key grooves 15 is 1200-1500mm, the depth of any key groove 15 is 15-20mm, and the side length of the key groove 15 is 150-200mm. The key groove mainly improves the engagement force between the concrete cover 17 and the prefabricated floor slab.
[0027] The height of the limiting protruding edge 14 is 300-500mm. The limiting protruding edge here is higher than the traditional limiting protruding edge, mainly for limiting the pipe well protection piece 2 hoisted later.
[0028] The edge of the top plate 22 is outwardly extended by 50-100mm. Similar to the effect of an umbrella, wall rainwater is directly left to the side plate to cause water leakage. It should be noted that as long as the top plate of the pipe well protection piece 2 has no concave or is integrally waterproofed, there is no need to worry about water seepage.
[0029] The prefabricated floor slab 1 with the concrete cover 17 has a slope on the surface, the slope is inclined front and back, and the slope is 1-1.5°. The slope here is self-contained by the prefabricated floor slab 1, and the waterproof material and the concrete cover 17 are both laid with equal thickness, so the slope finally acts on the surface of the entire prefabricated member.
[0030] The waterproof material 16 is a polyethylene film isolation waterproof material 16. It can be hot-stuck and hot-formed, which is convenient for waterproof connection of adjacent two waterproof materials and ensures that it is in the key groove.
[0031] Finally, it should be noted that: the above only describes preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features, as long as they are within the spirit and principles of the present application.
