Description

Technical Field

[0001] The utility model belongs to the technical field of building structure roof insulation, and particularly relates to a composite insulation structure for an upright roof. Background Art

[0002] The thermal insulation structure of concrete building roof has an important impact on indoor thermal insulation, especially for the upright roof structure. In order to improve the thermal insulation effect of the roof, at present, the method of grooving the roof structure to bury the exhaust pipe or grooving after pouring the slope layer is mostly used to increase the air permeability of the roof thermal insulation structure. On the one hand, this method is easy to damage the building structure and generate construction waste. On the other hand, if you choose to directly groove and then cover the insulation board, if the longitudinal and transverse grooves are blocked, it will be detrimental to the air permeability of the insulation layer, affecting the thermal insulation effect, reducing the service life and low strength of the insulation structure. In addition, after the insulation board is laid, the upper concrete of the upright roof often has mesh cracks, which poses certain quality risks. Therefore, a composite thermal insulation structure for the upright roof is needed to solve this problem. Utility Model Content

[0019] Example 1

[0020] This embodiment provides Figures 1 to 3 The composite insulation structure for an upright roof shown in FIG. 1 includes a horizontally arranged insulation layer 1, which is a breathable thermal insulation layer with a thickness of 1 cm. An extruded polystyrene layer 2 with a thickness of not less than 4 cm, which can be further determined based on local energy-saving requirements, is provided on the upper surface of the extruded polystyrene layer 2. The insulation layer 3 is a hard calcium silicate insulation layer with a thickness of 2 cm.

[0021] Several exhaust components 4 are arranged horizontally between the insulation layer 1 and the extruded polystyrene layer 2. The exhaust components 4 include two air intake pipes 41 embedded in the lower surface of the extruded polystyrene layer 2. The two air intake pipes 41 are arranged horizontally in a cross shape. A number of air intake holes 42 are provided on the air intake pipe 41. The air intake holes 42 are arranged at intervals along the length direction of the air intake pipe 41. The spacing between the air inlets on the air intake pipe 41 is 5 cm. The connecting point of the two air intake pipes 41 is connected with a vertically arranged exhaust pipe 43. The exhaust pipe 43 vertically passes through the extruded polystyrene layer 2 and the thermal insulation layer 3 upward, and the upper end of the exhaust pipe 43 is flush with the upper surface of the thermal insulation layer 3. A four-way base 44 is provided at the connecting point of the two air intake pipes 41 in the exhaust component 4. The cross intersection of the two air intake pipes 41 is connected through the four-way base 44. The lower end of the exhaust pipe 43 is connected to the upper side of the four-way base 44. The upper inner diameter of the four-way base 44 is 5 cm, and the lower inner diameter of the four-way base 44 is 7 cm.

[0022] When in use, the water vapor in the composite thermal insulation structure passes through the thermal insulation layer 1 and enters from the air inlet hole 42 in the air inlet pipe 41 embedded in the extruded polystyrene layer 2. Then the water vapor is collected and discharged from the exhaust pipe 43 through the four-way base 44. In this way, the composite thermal insulation structure of the upright roof can ensure that the water vapor in the thermal insulation layer 1 is removed in time, extending the service life of the thermal insulation layer 1. There is no need to groove the concrete structure layer to bury the air permeable pipe, which has a good thermal insulation effect and effectively prevents concrete cracking.

[0023] Among them, each air intake pipe 41 is configured as a PVC socket-type pipe, and one end of each air intake pipe 41 is a socket 5, and the other end is a spigot 6. The two adjacent air intake pipes 41 are connected through the socket 5 and the spigot 6. It can not only be mass-produced and processed to reduce production costs, but also facilitate construction personnel to carry out construction and installation, reduce labor intensity, and improve construction efficiency.

[0024] Furthermore, a rigid steel frame 7 is embedded in the insulation layer 3, and the rigid steel frame 7 protrudes upward and is exposed on the upper surface of the insulation layer 3, wherein the rigid steel frame 7 is exposed outward by 2 cm, and the diameter of the steel bar is not less than 4 mm. After the construction of the insulation structure is completed, the steel mesh is tied on the rigid steel frame 7, and concrete is poured on the upper layer. The setting of the rigid steel frame 7 ensures that the tied steel bars can be in the middle of the upper concrete, effectively preventing the concrete from cracking.

[0025] In summary, the utility model provides a composite thermal insulation structure for an upright roof. The composite thermal insulation structure of the upright roof can ensure that water vapor in the insulation layer is removed in time, and there is no need to groove the concrete structure layer to bury air vents. The service life is extended and the thermal insulation effect is better. In addition, the rigid steel frame 7 embedded in the top layer is used to support the steel mesh, ensuring that the steel mesh is located in the middle of the concrete of the protective layer of the insulation structure, effectively preventing the concrete from cracking, and the composite thermal insulation structure has high strength and is not easy to be damaged.
