Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to a prefabricated slope roof. Background Art

[0002] A pitched roof is a building roof structure with a slope greater than or equal to 10 degrees and less than 75 degrees. The pitched roof can not only quickly drain rainwater, which is beneficial to reducing roof leakage, but also provide a variety of roof shapes. Pitched roofs are widely used in urban and new rural buildings. The traditional construction process of a pitched roof includes: formwork support - steel bar binding of the roof slab - concrete pouring of the roof slab - curing - leveling - installation of a wire mesh cement polystyrene sandwich panel - construction of SBS modified bitumen waterproof coiled material - hanging of concrete colored tiles. The special shape of the pitched roof leads to problems such as cumbersome formwork support, difficult construction of roof slab pouring, long construction period, and high labor cost during its construction. Therefore, in recent years, prefabricated buildings, especially steel structure prefabricated buildings, have been vigorously promoted and developed. Prefabrication technology is widely favored in the construction field due to its advantages such as simple construction process flow and short construction period.

[0003] The prior art is a Chinese patent with the publication number CN205348515U and the publication date of June 29, 2016, which discloses a prefabricated inclined roof system. The technical solution is: a prefabricated inclined roof system includes a precast concrete roof truss and precast roof slabs. Embedded angle steels are arranged on the precast concrete roof truss and the precast roof slabs. The precast roof slabs are erected on the precast concrete roof truss, and the precast roof slabs and the precast concrete roof truss are welded and fixed through the embedded angle steels.

[0004] Since the precast panel of the above prefabricated inclined roof system is a full-thickness precast slab and there is no post-cast concrete layer on site, the interface between the precast slab and the post-cast joint area is a waterproof weak part, resulting in poor waterproof performance of the prefabricated inclined roof system. In addition, the prefabricated inclined roof system facilitates roof drainage by setting the inclination angles of the large-slope roof slab and the small-slope roof slab. However, during the installation process, the horizontal inclination angle of the precast roof slab is fixedly set, and it is difficult to adjust the position of the precast roof slab at the installation site. Summary of the Invention

[0005] To solve the above problems, the present invention provides a prefabricated slope roof. By using the prefabricated slope roof provided by the present invention, the construction process is simple, there is no need for support formwork and scaffolding, it is convenient to adjust the installation position, the installation speed is fast, and the waterproof performance is good.

[0006] An assembled slope roof provided by the present invention includes PEC beams and precast composite slabs for supporting the assembled slope roof. The assembled slope roof is composed of a cornice node, a ridge node, and a mid-slope node connected in sequence. The cornice node includes a cornice PEC beam and a cornice precast composite slab connected thereto. The ridge node includes a ridge PEC beam and a ridge precast composite slab connected thereto. The mid-slope node includes a mid-slope PEC beam and a mid-slope precast composite slab connected thereto. Concrete is cast on the cornice precast composite slab, the ridge precast composite slab, and the mid-slope precast composite slab, so that the cornice precast composite slab, the ridge precast composite slab, and the mid-slope precast composite slab are respectively assembled with the cornice PEC beam, the ridge PEC beam, and the mid-slope PEC beam to form an integral body. The cornice node, the ridge node, and the mid-slope node are jointly assembled to form a slope roof. By using the assembled slope roof provided by the present invention, formwork and scaffolding can be avoided, and the rapid installation of the composite slab can be ensured. After the composite slab is installed, steel bars are tied on the surface of the composite slab and then concrete is cast, with excellent waterproof performance, safe overall structure, high construction efficiency, and simple construction process.

[0007] The cornice node is that the cornice PEC beam and the cornice precast composite slab are connected by a first connecting piece. The first connecting piece passes through a through hole on the cornice precast composite slab and is connected to the cornice PEC beam. An adjusting mechanism for adjusting the installation position of the cornice precast composite slab is also provided at the connection between the first connecting piece and the cornice precast composite slab.

[0008] The cornice precast composite slab is laid on the cornice PEC beam. The first connecting piece can be an angle steel, which is strip-shaped and is vertically erected on the top of the cornice PEC beam and welded to the cornice PEC beam. A through hole is provided on the cornice precast composite slab, and the through hole is rectangular. The first connecting piece is inserted into the through hole on the precast composite slab to prevent the cornice precast composite slab from sliding down.

[0009] An adjusting mechanism for adjusting the installation position of the cornice precast composite slab is also provided between the first connecting piece and the cornice precast composite slab. When installing the precast cornice composite slab, the position of the cornice precast composite slab is adjusted through the adjusting mechanism according to the deflection situation of the cornice precast composite slab during on-site installation.

[0010] The adjusting mechanism is arranged in the through hole on the cornice precast composite slab. One side of the adjusting mechanism is attached to the inner wall of the through hole on the cornice precast composite slab, and the other side is attached to the first connecting piece.

[0011] When the first connecting member is inserted into the through hole on the eaves precast composite slab, a gap may be reserved between the first connecting member and the through hole at this time. The adjusting mechanism can be inserted into this gap to adjust the position of the eaves precast composite slab. Preferably, the adjusting mechanism is a wedge block. One side of the adjusting mechanism is in contact with the inner wall of the through hole on the eaves precast composite slab, and the other side is in contact with the first connecting member. When the position of the eaves precast composite slab needs to be adjusted towards the ridge direction, the adjusting mechanism is inserted towards the inner side of the through hole, and the contact surface between the adjusting mechanism and the through hole increases, causing the eaves precast composite slab to move obliquely upwards and tilt towards the ridge direction. When the eaves precast composite slab needs to move towards the eaves direction, the adjusting mechanism is pulled outwards to reduce the contact surface between the adjusting mechanism and the through hole, causing the eaves precast composite slab to move obliquely downwards and tilt towards the eaves direction.

[0012] A first concrete pouring layer is also poured at the post-cast area between the eaves PEC beam and the eaves precast composite slab and on the surface of the eaves precast composite slab.

[0013] Both the eaves PEC beam and the eaves precast composite slab are cuboids. The eaves precast composite slab is laid on the eaves PEC beam, and a certain included angle is formed between them. Therefore, there is a post-cast area between the eaves precast composite slab and the eaves PEC beam. Concrete is poured to fill the post-cast area between the eaves PEC beam and the eaves precast composite slab, making the fit between the eaves PEC beam and the eaves precast composite slab closer and more firm. After the position of the eaves precast composite slab is adjusted, surface steel bars are tied on the eaves precast composite slab, and a first concrete pouring layer is poured on the surface steel bars. After the first concrete pouring layer is cured, it forms an integral body with the eaves PEC beam.

[0014] The ridge node is that the ridge precast composite slab is arranged on both sides above the ridge PEC beam. A second concrete pouring layer is poured at the post-cast area between the ridge PEC beam and the ridge precast composite slab and on the surface of the ridge precast composite slab. Since the other end of the ridge precast composite slab connected to the eaves node is connected to one end of the eaves precast composite slab, and the eaves precast composite slab provides support for the ridge precast composite slab connected to the eaves node, therefore, the ridge precast composite slab connected to the eaves node does not need to be fixed with a connecting member.

[0015] There are two precast composite slabs for the ridge, distributed on both sides of the ridge. There is a post-cast area between the ridge PEC beam and the precast composite slab for the ridge. Concrete is poured to fill the post-cast area between the ridge PEC beam and the precast composite slab for the ridge, making the fit between the ridge PEC beam and the precast composite slab for the ridge closer and more firm. After the position of the precast composite slab for the ridge is adjusted, the surface reinforcement is tied, and a second concrete casting layer is poured on the surface reinforcement. After the second concrete casting layer is cured, it forms an integral body with the ridge PEC beam.

[0016] There is also a first shear-resistant long stud between the ridge PEC beam and the second concrete casting layer. The bottom of the first shear-resistant long stud is connected to the ridge PEC beam, and the first shear-resistant long stud penetrates through the post-cast area between the ridge PEC beam and the precast composite slab for the ridge.

[0017] The bottom of the first shear-resistant long stud is welded to the ridge PEC beam. The first shear-resistant long stud is arranged in the post-cast area between the precast composite slab for the ridge and the ridge PEC beam. The first shear-resistant long stud is connected to the second concrete casting layer by pouring concrete, and the shear force between the ridge PEC beam and the second concrete casting layer is transmitted to prevent slip at the joint surface.

[0018] The mid-slope joint is that the mid-slope PEC beam and the mid-slope precast composite slab are connected by a second connector.

[0019] There are two mid-slope precast composite slabs arranged at the mid-slope joint, which are respectively connected to the ridge joint and the eaves joint. The second connector is vertically welded to the top of the mid-slope PEC beam, and the mid-slope PEC beam and the mid-slope precast composite slab connected to the ridge joint are welded and fixed through the second connector.

[0020] The mid-slope precast composite slab also includes embedded parts for fixing the mid-slope precast composite slab, and the embedded parts are connected to the second connector.

[0021] The embedded parts are arranged inside the mid-slope precast composite slab connected to the ridge joint to fix the mid-slope precast composite slab and prevent the mid-slope precast composite slab from sliding down.

[0022] The bottom of the embedded part is welded and fixed to the top end of the second connector, and the mid-slope PEC beam and the mid-slope precast composite slab are fixed through the embedded parts and the second connector.

[0023] A third concrete casting layer is poured at the post-cast area between the mid-slope precast composite slab and the mid-slope PEC beam and on the surface of the mid-slope precast composite slab.

[0024] Both ends of the mid-slope node are respectively connected to the ridge node and the eaves node. There is a post-cast area between the mid-slope PEC beam and the mid-slope precast composite slab. The post-cast area between the mid-slope PEC beam and the mid-slope precast composite slab is filled with a concrete layer, making the fit between the mid-slope PEC beam and the mid-slope precast composite slab closer and more firm. After the position of the mid-slope precast composite slab is adjusted, the surface steel bars are tied, and a third concrete casting layer is cast on the surface steel bars. After the third concrete casting layer is cured, it forms an integral body with the mid-slope PEC beam.

[0025] There is also a second shear-resistant long stud between the mid-slope PEC beam and the third concrete casting layer. The bottom of the second shear-resistant long stud is connected to the mid-slope PEC beam, and the second shear-resistant long stud penetrates through the post-cast area between the mid-slope PEC beam and the mid-slope precast composite slab.

[0026] The bottom of the second shear-resistant long stud is welded to the mid-slope PEC beam. The second shear-resistant long stud is arranged in the post-cast area between the mid-slope precast composite slab and the mid-slope PEC beam. The second shear-resistant long stud is connected to the third concrete casting layer by casting concrete, transferring the shear force between the mid-slope PEC beam, the mid-slope precast composite slab, and the third concrete casting layer, and preventing slip at the joint surface.

[0027] The beneficial effects of an assembled slope roof provided by the present invention are as follows:

[0028] 1. Compared with the prior art, the eaves node, the ridge node, and the mid-slope node are assembled into one body. After tying the steel bars on the precast composite slab and then casting concrete, there is no need for support formwork and scaffolding. The overall structure is safe, and the construction process flow is simple and efficient.

[0029] 2. The precast composite slab is laid on the PEC beam, and then a concrete casting layer is set to make the slope roof form an integral waterproof structure, improving the waterproof performance of the slope roof structure.

[0030] 3. An installation adjustment mechanism is inserted into the precast composite slab, which is convenient for adjusting the installation position of the precast composite slab during construction. The operation is simple and the installation speed is fast.

[0031] 4. The precast composite slab is connected to the PEC beam through connectors, making the connection between the precast composite slab and the PEC beam more firm and preventing the precast composite slab from sliding down. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, all other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0038] As Figure 1As shown in the figure, a prefabricated slope roof provided by the present invention includes PEC beams and precast composite slabs for supporting the prefabricated slope roof. The prefabricated slope roof is composed of an eave node 1, a ridge node 2, and a mid-slope node 3 connected in sequence. The eave node 1 includes an eave precast composite slab 5 connected to an eave PEC beam 4. The ridge node 2 includes a ridge precast composite slab 11 connected to a ridge PEC beam 10. The mid-slope node 3 includes a mid-slope precast composite slab 15 connected to a mid-slope PEC beam 14. Concrete is cast in place on the eave precast composite slab 5, the ridge precast composite slab 11, and the mid-slope precast composite slab 15 so that the eave precast composite slab 5, the ridge precast composite slab 11, and the mid-slope precast composite slab 15 are respectively assembled with the eave PEC beam 4, the ridge PEC beam 10, and the mid-slope PEC beam 14 to form an integral body. The eave node 1, the ridge node 2, and the mid-slope node 3 are jointly assembled to form a slope roof. By using the prefabricated slope roof provided by the present invention, it is possible to achieve no formwork and no scaffolding, and ensure the rapid installation of the composite slabs. After the composite slabs are installed, steel bars are tied on the surface of the composite slabs and then concrete is cast in place. The waterproof performance is excellent, the overall structure is safe, and the construction efficiency is high and the construction process is simple.

[0039] As Figure 2 As shown in the schematic diagram of the eave node, the eave node 1 is connected between the eave PEC beam 4 and the eave precast composite slab 5 through a first connecting member 7. The first connecting member 7 passes through a through hole 8 on the eave precast composite slab and is connected to the eave PEC beam 4. An adjusting mechanism 6 for adjusting the installation position of the eave precast composite slab 5 is further provided at the connection between the first connecting member 7 and the eave precast composite slab 5.

[0040] The eave precast composite slab 5 is laid on the eave PEC beam 4. The first connecting member 7 can be an angle steel. The angle steel is long strip-shaped and is vertically erected on the top of the eave PEC beam 4 and welded to the eave PEC beam 4 through the first connecting member 7. A through hole 8 is provided on the eave precast composite slab 5. The through hole 8 is rectangular. The first connecting member 7 is inserted into the through hole 8 on the precast composite slab 5 to prevent the eave precast composite slab 5 from sliding down.

[0041] An adjusting mechanism 6 for adjusting the installation position of the eave precast composite slab 5 is further provided between the first connecting member 7 and the eave precast composite slab 5. When installing the precast eave composite slab 5, the position of the eave precast composite slab 5 is adjusted through the adjusting mechanism 6 according to the deviation condition of the eave precast composite slab 5 during on-site installation. The adjusting mechanism 6 is arranged in the through hole 8 on the eave precast composite slab 5. One side of the adjusting mechanism 6 is attached to the inner wall of the through hole 8 on the eave precast composite slab 5, and the other side is attached to the first connecting member 7.

[0042] When the first connecting member 7, i.e., the angle steel, is inserted into the through hole 8 on the eave precast composite slab 5, a gap can be reserved between the first connecting member 7 and the through hole 8. The adjusting mechanism 6 can be inserted into this gap to adjust the position of the eave precast composite slab 5. Preferably, the adjusting mechanism 6 is a wedge block. One side of the adjusting mechanism 6 is in contact with the inner wall of the through hole 8 on the eave precast composite slab 5, and the other side is in contact with the first connecting member 7. When the position of the eave precast composite slab 5 needs to be adjusted towards the ridge direction, the adjusting mechanism 6 is inserted towards the inner side of the through hole 8. The contact surface between the adjusting mechanism 6 and the through hole 8 increases, causing the eave precast composite slab 5 to move upward and tilt towards the ridge direction. When the eave precast composite slab 5 needs to move towards the eave direction, the adjusting mechanism 6 is pulled outwards to reduce the contact surface between the adjusting mechanism 6 and the through hole 8, causing the eave precast composite slab 5 to move obliquely downwards and tilt towards the eave direction.

[0043] A first concrete casting layer 9 is also cast at the post-cast area between the eave PEC beam 4 and the eave precast composite slab 5 and on the surface of the eave precast composite slab 5.

[0044] Both the eave PEC beam 4 and the eave precast composite slab 5 are cuboids. The eave precast composite slab 5 is laid on the eave PEC beam 4, and there is a certain included angle between them. Therefore, there is a post-cast area between the eave PEC beam 4 and the eave precast composite slab 5. Concrete is cast to fill the post-cast area between the eave PEC beam 4 and the eave precast composite slab 5, making the eave PEC beam 4 and the eave precast composite slab 5 fit more closely and firmly. After the position of the eave precast composite slab 5 is adjusted, surface reinforcement is tied on the eave precast composite slab 5, and the first concrete casting layer 9 is cast on the surface reinforcement. After the first concrete casting layer 9 is cured, it forms an integral body with the eave PEC beam 4.

[0045] As Figure 3 As shown in the schematic diagram of the ridge node, the ridge node 2 has the ridge precast composite slab 11 arranged on both sides above the ridge PEC beam 10. A second concrete casting layer 12 is cast at the post-cast area between the ridge PEC beam 10 and the ridge precast composite slab 11 and on the surface of the ridge precast composite slab 11. Since the other end of the ridge precast composite slab 11 connected to the eave node 1 is connected to one end of the eave precast composite slab 5, and the eave precast composite slab 5 provides support for the ridge precast composite slab 11 connected to the eave node 1, therefore, the ridge precast composite slab 11 connected to the eave node 1 does not need to be fixed with a connecting member.

[0046] There are two ridge precast composite slabs 11, which are distributed on both sides of the ridge. There is a post-cast area between the ridge PEC beam 10 and the ridge precast composite slab 11. Concrete is poured to fill the post-cast area between the ridge PEC beam 10 and the ridge precast composite slab 11, making the fit between the ridge PEC beam 10 and the ridge precast composite slab 11 closer and firmer. Surface reinforcement is tied on the ridge precast composite slab 11, and a second concrete casting layer 12 is poured on the surface reinforcement. After the second concrete casting layer 12 is cured, it forms an integral body with the ridge PEC beam 10.

[0047] Between the ridge PEC beam 10 and the second concrete casting layer 12, there is also a first shear-resistant long stud 13. The bottom of the first shear-resistant long stud 13 is connected to the ridge PEC beam 10, and the first shear-resistant long stud 13 penetrates through the post-cast area between the ridge PEC beam 10 and the ridge precast composite slab 11.

[0048] The bottom of the first shear-resistant long stud 13 is welded to the ridge PEC beam 10. The first shear-resistant long stud 13 is arranged at the post-cast area between the ridge precast composite slab 11 and the ridge PEC beam 10. The first shear-resistant long stud 13 is connected to the second concrete casting layer 12 by pouring concrete, transmitting the shear force between the ridge PEC beam 10 and the second concrete casting layer 12 and preventing slip at the joint surface.

[0049] The mid-slope joint 3 is that the mid-slope PEC beam 14 and the mid-slope precast composite slab 15 are connected by a second connector 16.

[0050] As Figure 4 As shown in the schematic diagram of the mid-slope joint, there are two mid-slope precast composite slabs 15 arranged on the mid-slope joint 3. One is connected to the ridge precast composite slab 11 of the ridge joint 2, and the other is connected to the eaves precast composite slab 5 of the eaves joint 1. There is a post-cast area between the two mid-slope precast composite slabs. The second connector 16 is vertically welded to the top of the mid-slope PEC beam 14, and the mid-slope PEC beam 14 and the mid-slope precast composite slab 15 connected to the ridge joint 2 are welded and fixed through the second connector 16.

[0051] The mid-slope precast composite slab 15 also includes a buried part 17 for fixing the precast composite slab, and the buried part 17 is connected to the second connector 16.

[0052] The embedded part 17 is arranged inside the mid-slope precast composite slab 15 connected to the ridge node 2 to fix the mid-slope precast composite slab 15 and prevent the mid-slope precast composite slab 15 from sliding down. The bottom of the embedded part 17 is welded and fixed to the top end of the second connecting member 16, and the mid-slope PEC beam 14 and the mid-slope precast composite slab 15 are fixed through the embedded part 17 and the second connecting member 16.

[0053] A third concrete pouring layer 18 is poured at the post-cast area between the mid-slope precast composite slab 15 and the mid-slope PEC beam 14 and on the surface of the mid-slope precast composite slab 15.

[0054] Both ends of the mid-slope node 3 are respectively connected to the ridge node 2 and the eaves node 1. There is a post-cast area between the mid-slope PEC beam 14 and the mid-slope precast composite slab 15. Concrete is poured to fill the post-cast area between the mid-slope PEC beam 14 and the mid-slope precast composite slab 15, so that the mid-slope PEC beam 14 and the mid-slope precast composite slab 15 fit more closely and firmly. The surface layer steel bars are tied on the mid-slope precast composite slab 15, and the third concrete pouring layer 18 is poured on the surface layer steel bars. After the third concrete pouring layer 18 is cured, it forms an integral body with the mid-slope PEC beam 14.

[0055] A second shear-resistant long stud 19 is further included between the mid-slope PEC beam 14 and the third concrete pouring layer 18. The bottom of the second shear-resistant long stud 19 is connected to the mid-slope PEC beam 14, and the second shear-resistant long stud 19 penetrates through the post-cast area between the mid-slope PEC beam 14 and the mid-slope precast composite slab 15.
