[0002] In recent years, many civil buildings, especially residential projects, have added a sloping edge to the roof to enhance the overall decorative effect, imitating the style of ancient Chinese architecture.

[0003] The lower half of the sloping member extends beyond the parapet wall, forming a closed triangular area with the extended roof slab, and this area is located on the outside of the building's exterior wall.

[0004] The applicant has discovered that the prior art has at least the following technical problems:

[0005] The current construction of the roof edge slope component structure is quite difficult, making it hard to ensure the flatness of the slope, which in turn affects the overall effect of the shape. In addition, the closed triangular area is hollow, making the formwork difficult to set up and unable to be recycled, resulting in poor economic efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a roof edge sloping component structure and construction method to solve the problems of current roof edge sloping component structures, which are difficult to construct, struggle to ensure the flatness of the slope, thus affecting the overall aesthetic effect. Furthermore, the closed triangular area is hollow, making formwork erection difficult and non-recyclable, resulting in poor economic efficiency. The various technical effects of the preferred technical solutions provided by this invention are detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides a roof edge sloping component structure, comprising a precast strip slab, an external cantilever slab, a first support, a second support, and a sloping cast-in-place component, wherein:

[0009] The first support is disposed on the outer cantilever plate, and the first support is provided with an inclined surface;

Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] This invention provides a roof edge slope component structure. Figure 1 This is a structural schematic diagram of this embodiment, as shown below. Figure 1 As shown, it includes a precast slab 1, an external cantilever slab 2, a first support 3, a second support 4, and a sloping cast-in-place component 5.

[0040] The first support 3 is set on the cantilever slab 2 and has an inclined surface 31; the second support 4 protrudes from the outer wall 7 and is set on the outer wall 7, and is located above the first support 3; the precast strip 1 is inclined and its two ends abut against the first support 3 and the second support 4 respectively, so that the precast strip 1, the cantilever slab 2 and the outer wall 7 form a triangular structure; the precast strip 1 is provided with steel bars 6 inside; the inclined cast-in-place component 5 is connected to the outer wall 7, located above the precast strip 1, and has the same inclination angle as the precast strip 1.

[0041] This roof edge sloping component structure, by setting up precast strips 1, external cantilever slabs 2, first supports 3, second supports 4, and sloping cast-in-place components 5, optimizes the structural form while satisfying the decorative effect. By splitting the closed triangular area, some of the sloping cast-in-place components in this area are replaced with precast components. The two ends of the precast components are connected to the cast-in-place structure, making the remaining cast-in-place structure more regular in shape, making formwork erection and concrete construction more convenient, and making it easier to control the flatness of the slope. During construction, by adopting this roof edge sloping component structure, the construction difficulty of the roof sloping components can be reduced, work efficiency and appearance quality can be improved, and the problem of difficult formwork recovery can be avoided.

[0042] As an optional implementation, Figure 2 This is a schematic diagram of the precast strip structure in this embodiment, as shown below. Figure 2 As shown, the precast panel 1 includes an integrally formed first body 11 and a second body 12.

[0043] Specifically, the cross-section of the first main body 11 adopts a rectangular structure, and the cross-section of the second main body 12 adopts a right-angled trapezoidal structure.

[0044] The first body 11 and the second body 12 are set at an obtuse angle. In use, the first body 11 abuts against the inclined surface 31 of the first support 3, and the second body 12 abuts against the second support 4. By setting the prefabricated strip 1 including the first body 11 and the second body 12 which are formed integrally with an obtuse angle, the contact between the prefabricated strip 1 and the first support 3 and the second support 4 can be increased, thereby improving the safety and stability during use.

[0045] As an optional implementation, the first support 3 has a right trapezoidal cross-section, with the inclined surface of the trapezoid forming an obtuse angle with the outer cantilever plate 2. The second support 4 has a rectangular cross-section.

[0046] In this embodiment, the first support 3 and the outer cantilever plate 2, and the second support 4 and the outer wall 7 are all integral structures, so as to make the overall stability of this roof edge slope component structure better.

[0047] As an optional implementation method, Figure 3 This is a structural schematic diagram of the reinforcement of the precast strip slab in this embodiment, as shown below. Figure 3 As shown, the reinforcing bar 6 includes a first embedded part 61, a second embedded part 62 and a third embedded part 63.

[0048] The first embedded part 61 and the second embedded part 62 form an obtuse angle; the second embedded part 62 and the third embedded part 63 form a right angle. The first embedded part 61 extends into the interior of the first main body 11, one end of the second embedded part 62 is connected to the first embedded part 61 and is located inside the first main body 11; the other end of the second embedded part 62 extends out of the precast strip 1 from the second main body 12, and the third embedded part 63 is connected to the other end of the second embedded part 62.

[0049] As an optional implementation, a filling layer 8 is also included, which is placed between the second support 4 and the precast slab 1. Specifically, the filling layer 8 is made of fine aggregate concrete.

[0050] A construction method for a roof edge sloping member structure, using the aforementioned roof edge sloping member structure, includes the following steps:

[0052] During the construction of the top floor of the building, the roof floor slab 9, the external cantilever slab 2 and the first support 3 are poured as required, and the steel reinforcement of the roof components is reserved.

[0053] Fabricate precast strip 1 and embed steel bars 6 inside it;

[0054] S2: Tie the reinforcing bars of the vertical and sloping cast-in-place components of the roof, set up the formwork, and pour the concrete;

[0055] S3: After the other cast-in-place structures are completed and meet the strength requirements, place the two ends of the precast strip 1 on the first support 3 and the second support 4 respectively, and arrange them in sequence along the edge of the roof, connecting them tightly to form a ring-shaped whole.

[0056] S4: At the connection between the second support 4 and the precast strip 1, fine stone concrete is filled, and vibration and finishing treatment are carried out. The finishing slope is consistent with that of the precast strip 1 and the inclined cast-in-place component 5.

[0057] S5: After curing is completed, proceed with the subsequent leveling layer, waterproofing layer and decorative layer.

[0058] The construction method of this roof edge sloping component structure optimizes the structural form while satisfying the decorative effect. By splitting the closed triangular area, some of the sloping cast-in-place components in this area are replaced with precast components. The two ends of the precast components are connected to the cast-in-place structure, making the remaining cast-in-place structure more regular in shape. The formwork erection and concrete construction are more convenient, the flatness of the sloping surface is easier to control, and the construction difficulty of the roof sloping components is reduced. This improves work efficiency and appearance quality, and avoids the problem of difficult formwork recovery.
