Description

Technical Field

[0001] The present invention relates to the technical field of roof structures, and in particular, to an assembled multifunctional roof structure. Background Art

[0002] Conventional roof designs mainly include three modules: indoor space, roof structure, and outdoor space, among which the roof structure is the key point of the design. The roof structure design mainly includes the following five parts:

[0003] (1) Roof load-bearing structure: mainly the components that bear the roof load;

[0004] (2) Slope design: build a certain gentle slope in the designed drainage direction, and direct the roof rainwater to the rainwater drainage system of the building and the city through downspouts;

[0005] (3) Laying of insulation layer: As an external structure, the roof should have good heat insulation and heat preservation functions. In cold seasons, indoor heating is generally required. To ensure the normal indoor temperature and reduce energy consumption, the roof should take heat preservation measures. For hot seasons, to avoid the influence of strong solar radiation and high temperature on the indoor environment, heat insulation measures are usually taken on the roof;

[0006] (4) Waterproof layer: The main function of the waterproof layer is to prevent the water in the roof space from entering the roof and then damaging the building's maintenance structure. The roof waterproof layer mainly plays a waterproof role by laying waterproof coiled materials and brushing waterproof materials;

[0007] (5) Cement layer: Laid on top of the waterproof layer, it can enhance the service life of the waterproof layer. Some buildings will also lay roof tiles to pursue the beauty of the roof.

[0008] This conventional structural design is mainly to meet the functions of waterproofing, heat insulation, and heat preservation, but there are still the following deficiencies:

[0009] (1) Poor heat insulation and heat preservation effect, which leads to the easy transfer of indoor heat to the outside in winter, resulting in a decrease in indoor temperature, and the easy transfer of outdoor heat to the inside in summer, causing an increase in indoor temperature and reducing the living comfort;

[0010] (2) The laying quality of the heat insulation and heat preservation layer in the roof structure is highly correlated with the technical level of construction workers. Therefore, the quality is highly random, and it is very difficult to control the consistency and standardization;

[0011] (3) All kinds of processes on the roof need to be carried out on-site and need to be carried out in series, resulting in a long construction period.

[0012] (4) Traditional roof designs do not consider the function of sound insulation. As society develops, more and more roofs are being developed and used. For example, the currently popular rooftop playgrounds. In this case, the roof structure needs to be enhanced with sound insulation design. Summary of the Invention

[0013] The purpose of the present invention is to make up for the deficiencies of the existing technology and provide an assembled multi-functional roof structure.

[0014] The present invention is achieved through the following technical solutions:

[0015] An assembled multi-functional roof structure includes load-bearing walls and parapet walls at both ends of the load-bearing walls. A lower double-sided self-adhesive waterproof coiled material is laid on the outer side of the load-bearing wall. An assembled roof module with a positive buckle is laid outside the lower double-sided self-adhesive waterproof coiled material. An upper heat-reflective waterproof coiled material is laid outside the assembled roof module with a positive buckle.

[0016] An assembled roof module with a reverse buckle is also laid between the lower double-sided self-adhesive waterproof coiled material and the assembled roof module with a positive buckle.

[0017] A heat-reflective film is laid between the assembled roof module with a positive buckle and the assembled roof module with a reverse buckle.

[0018] Polypropylene loose foam particles are filled in the gaps between the assembled roof module with a positive buckle and the assembled roof module with a reverse buckle.

[0019] Each of the assembled roof modules includes a water receiving tray. A buckle that extends downward and turns upward is provided at one end of the water receiving tray. Adjacent assembled roof modules are buckled together through the buckle. A plurality of conical columns integrally formed with the water receiving tray are evenly distributed on the water receiving tray. The conical columns are hollow. A convex platform protruding outward or a concave cavity recessed inward is provided at the bottom end of the conical column. The convex platforms and concave cavities of the conical columns of the assembled roof modules with positive and reverse buckles cooperate with each other.

[0020] An air vent riser is provided above the upper heat-reflective waterproof coiled material. The lower end of the air vent riser is communicated with the inside of the assembled roof module with a positive buckle.

[0021] The top end cover of the air vent riser is made of a shape memory metal cover.

[0022] Drain pipes passing through the parapet walls are fixed on both sides of the load-bearing wall. One end of the drain pipe is communicated with the assembled roof module with a reverse buckle.

[0023] Both the water receiving tray and the conical columns are made of plastic material, metal material or concrete material, and the material is selected according to actual needs.

[0024] The advantages of the present invention are:

[0025] In the present invention, the prefabricated roof module can realize the prefabricated construction of the roof. On the one hand, it can shorten the construction period, and on the other hand, it can improve the consistency during the construction process;

[0026] The roof system designed in the present invention can effectively play the roles of heat insulation, heat preservation, ventilation and sound insulation;

[0027] In the present invention, the system structure can enhance the heat insulation and heat preservation effects according to different seasons (ambient temperature);

[0028] In the present invention, the prefabricated roof module made of plastic material and the heat-reflective film can be combined and used according to actual performance requirements. This structure has the functions of heat insulation, heat preservation, ventilation, sound insulation and enhanced waterproofing;

[0029] In the present invention, the combined use of the loading arm and the drain pipe can, on the one hand, drain leaks, and on the other hand, enhance the heat insulation and heat preservation effects according to the change of the ambient temperature. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] As Figure 1 , 2 shown, a prefabricable multi-functional roof structure includes a load-bearing wall 1 and parapet walls 2 at both ends of the load-bearing wall. A lower double-sided self-adhesive waterproof coiled material 3 is laid on the outer side of the load-bearing wall 1, and a prefabricated roof module 4 with a positive buckle is laid on the outside of the lower double-sided self-adhesive waterproof coiled material 3, and an upper heat-reflective waterproof coiled material 5 is laid on the outside of the prefabricated roof module 4 with a positive buckle.

[0037] An inverted prefabricated roof module 6 is also laid between the lower double-sided self-adhesive waterproof coiled material 3 and the prefabricated roof module 4 with a positive buckle.

[0038] A heat-reflecting film 7 is laid between the right-handed assembled roof modules 4 and the left-handed assembled roof modules 6.

[0039] Polypropylene loose foam particles 8 are filled in the gaps between the right-handed assembled roof modules 4 and the left-handed assembled roof modules 6.

[0040] As Figure 3 、 4 、shown in Figure 5, each of the assembled roof modules includes a water receiving tray 9. A buckle 10 that extends downward and turns upward is provided at one end of the water receiving tray 9. Adjacent assembled roof modules are buckled through the buckle 10. A plurality of conical columns 11 integrally formed with the water receiving tray 9 are evenly distributed on the water receiving tray 9. The conical columns 11 are hollow. A convex platform 12 protruding outward or a concave cavity 13 recessed inward is provided at the bottom end of the conical column 11. The convex platforms 12 and the concave cavities 13 of the conical columns of the right-handed and left-handed assembled roof modules 4 and 6 cooperate with each other.

[0041] A vent stack 14 is provided above the upper heat-reflecting waterproof coiled material 3. The lower end of the vent stack 14 is communicated with the inside of the right-handed assembled roof module 4.

[0042] The top end cover 15 of the vent stack 14 is made of a shape memory metal cover, as Figure 6 shown.

[0043] Drain pipes 16 penetrating through the parapet wall 2 are respectively fixed on both sides of the load-bearing wall 1. One end of the drain pipe 16 is communicated with the left-handed assembled roof module 6.

[0044] Both the water receiving tray 9 and the conical columns 11 are made of plastic material, metal material or concrete material. The material is selected according to actual needs. In the embodiment of the present invention, plastic material is adopted.

[0045] For the plastic material assembled roof module, turned-up buckles 10 are respectively provided on both sides, and adjacent assembled roof modules are buckled and connected through the buckles 10. The overall stability of the stacked assembled roof modules is higher. A waterproof material is laid at the bottom before the assembled roof modules are stacked, which further plays a role in strengthening the roof waterproofing.

[0046] The internal space formed after the assembled roof modules are combined is filled with polypropylene loose foam particles 8 to play a role in heat preservation and heat insulation of the roof.

[0047] The wall structure is mainly composed of a parapet wall and a load-bearing wall.

[0048] To further reinforce the roof, a waterproof material is laid before stacking the bottom of the prefabricated roof modules. In this invention, laying a double-sided self-adhesive waterproof coiled material in advance is taken as an example. Meanwhile, in order to play a role in heat insulation and preservation in this invention, the prefabricated roof modules are stacked in the following combined ways, and their heat insulation and preservation performance is improved in turn.

[0049] (1) Lower layer double-sided self-adhesive waterproof coiled material + prefabricated roof module (positive buckle) + upper layer heat-reflective waterproof coiled material. When the heat insulation and preservation performance needs to be further improved, the following second layout method in this invention can be adopted:

[0050] (2) Lower layer double-sided self-adhesive waterproof coiled material + prefabricated roof module (negative buckle) + prefabricated roof module (positive buckle) + upper layer heat-reflective waterproof coiled material. In this structure, due to the stacking of the prefabricated roof modules, the heat transfer thickness formed by the prefabricated roof modules increases, and the heat transfer coefficient is further reduced. Therefore, the heat preservation and insulation performance can be improved. In order to enhance the installation stability, the positive buckle and negative buckle of the prefabricated roof modules need to correspond to the corresponding module bite nodes. When the heat insulation and preservation performance needs to be further improved, the following third layout method in this invention can be adopted:

[0051] (3) Lower layer double-sided self-adhesive waterproof coiled material + prefabricated roof module (negative buckle) + heat-reflective film + prefabricated roof module (positive buckle) + upper layer heat-reflective waterproof coiled material. When the air thickness formed in the module increases to a certain extent, increasing the stacking height of the prefabricated roof modules can no longer reduce the heat transfer coefficient and enhance the heat insulation and preservation effect. On the contrary, it may even cause air convection in the prefabricated roof modules and weaken the heat insulation and preservation effect. At this time, if it is necessary to enhance the heat insulation and preservation effect, the third layout method in this invention can be adopted, and the heat-reflective film is arranged between the upper and lower prefabricated roof modules. This is because according to the heat transfer principle, when the thickness of the enclosed air increases to a certain extent, increasing the thickness of the enclosed space will no longer significantly improve the heat insulation and preservation effect, and even the performance may decline. The arrangement of the heat-reflective film can divide the air cavity formed by the prefabricated roof modules into spaces with smaller thicknesses. This arrangement can enhance the heat insulation and preservation performance of the combined prefabricated roof modules. Therefore, in actual projects, the stacking layers of the prefabricated roof modules and the combination arrangement of the heat-reflective film can be carried out according to actual needs.

[0052] Another innovation in this invention is the combined design of the loading arm and the drain (vent) pipe.

[0053] Such as Figure 6The top of the loading arm is shown with a shape memory metal cover. In the present invention, a shape memory metal with a deformation temperature of 25°C is taken as an example (in actual engineering, shape memory metals with different deformation temperatures can be selected according to needs). When the ambient temperature of the shape memory metal cover > 25°C, the shape memory metal cover will be in a curled state, that is, the high-temperature state in the figure, and at this time the loading arm is unobstructed; when the ambient temperature of the shape memory metal cover ≤ 25°C, the shape memory metal cover will be in a straight state, that is, the low-temperature state in the figure, and at this time the loading arm is closed;

[0054] The combined design of the loading arm and the drain (vent) pipe in the present invention has the following functions:

[0055] (1) The function of draining water: When the waterproof layer of the roof leaks and water flows into the roof insulation layer, the seepage water can be discharged through the drain pipe at this time, which can reduce or avoid further damage to the bottom insulation layer;

[0056] (2) The function of enhancing waterproofing: In the present invention, there are two direct waterproofing layers arranged. The upper layer is a heat-reflective waterproof coiled material, and the lower layer is a double-sided self-adhesive waterproof coiled material. In order to enhance the waterproof performance of the roof, the present invention arranges a third waterproof system, that is, a water receiving tray is provided at the bottom of the lower assembled roof module. When the upper waterproof layer is damaged and rainwater enters the bottom of the water receiving tray, the water stored at the bottom of the water receiving tray can flow out through the drain (vent) pipe at this time, avoiding further infiltration of rainwater into the roof. This structure can enhance the waterproof performance of the roof and is the third waterproof system in the present invention;

[0057] (3) The function of heat insulation and ventilation: In the present invention, when the ambient temperature > 25°C, due to the arrangement of the insulation layer on the roof, the air temperature in the insulation layer will be higher than the ambient temperature. Due to the thermal pressure effect, air will enter the drain pipe, and the air will take away the temperature in the insulation layer and be discharged from the loading arm after passing through the insulation layer. Since part of the heat will be reflected out through the roof insulation system, the roof insulation and heat preservation system mainly plays a heat insulation role;

[0058] (4) The function of heat preservation: In the present invention, when the ambient temperature ≤ 25°C, the shape memory metal will be in a straight state, the loading arm is closed, and the drain pipe and the loading arm do not communicate with the outside. At this time, the roof insulation and heat preservation system mainly plays a heat preservation role.
