Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building structure engineering, and particularly relates to a super low energy consumption building roof exit hole structure. BACKGROUND

[0002] The super low energy consumption building refers to the building that meets the climatic characteristics and site conditions, reduces the building heating, air conditioning and lighting demand by the largest extent through passive building design, improves the energy equipment and system efficiency by the largest extent through active technical measures, fully utilizes the renewable energy, provides the comfortable indoor environment with less energy consumption, and the indoor environment parameters and energy efficiency indexes meet the nearly zero energy consumption technical standard (GB / T51350-2019) building.

[0003] The related research shows that the energy consumption of the building is influenced by the air tightness of the building. The key to guarantee the high energy consumption of the super low energy consumption building lies in the air tightness of the building structure. The air tightness refers to the air that cannot leak from the outside or the inside when the building structure is used. If the air tightness is poor, it is difficult to reduce the building energy consumption. The better the air tightness is, the higher the energy consumption efficiency is, and the smaller the building noise is. Therefore, the super low energy consumption building puts forward higher requirements for the air tightness of the building, and must reach a certain standard to guarantee the high energy consumption.

[0004] However, the integrity and continuity of the existing building air tightness layer are often damaged by the key nodes (such as the wall penetrating pipeline, roof overhanging structure and the like), especially the treatment of these key nodes of the roof exit hole is not refined, and there is no reasonable structure to guarantee that the air tightness of the roof exit hole structure is not damaged at the present stage. UTILITY MODEL CONTENTS

[0005] Therefore, the purpose of the utility model is to design a super low energy consumption building roof exit hole structure. Through reasonable structure design, the air tightness of the equipment pipeline when penetrating the interface between the inside and the outside of the building is effectively guaranteed, and the cold and heat bridges are isolated, so that the energy consumption is greatly saved, the energy consumption efficiency and the energy use efficiency are improved, the process is simplified, the construction cost is reduced, and the cost performance of the building is improved.

[0006] The utility model provides a super low energy consumption building roof exit hole structure, which comprises a building base layer, an overhanging structure and a pipeline. The overhanging structure is a pier-shaped structure, and is fixedly arranged on the upper part of the building base layer. The pipeline is embedded in the building base layer and the overhanging structure, and extends out of the roof from the upper surface of the overhanging structure.

[0007] The part of the pipeline protruding above the overhanging structure is detachably connected with an aluminum alloy sheet water cover, the inner diameter of the aluminum alloy sheet water cover is greater than the outer diameter of the overhanging structure, and the bottom surface height of the aluminum alloy sheet water cover is less than the top surface height of the overhanging structure; the upper part of the aluminum alloy sheet water cover is sleeved with an iron hoop, and the upper part of the aluminum alloy sheet water cover is press-connected with the pipeline through the iron hoop.

[0008] The part of the pipeline below the bottom surface of the building base is wrapped with a pipeline thermal insulation layer; and the inner side of the pipeline thermal insulation layer is provided with a waterproof and vapor barrier film at the connection position with the bottom side of the building base.

[0009] The utility model discloses the air tightness treatment of pipeline from the top of building base and the air tightness treatment of pipeline from the bottom of building base respectively, which guarantees the air tightness continuity of the whole roof opening structure.

[0010] Further, the gap at the connection position between the aluminum alloy sheet water cover and the pipeline and the gap at the connection position between the pipeline and the overhanging structure are sealed by sealing glue.

[0011] The small gaps at the connection position are completely and completely sealed by the sealing glue, which guarantees the strict air tightness between the pipeline and the building base.

[0012] Further, the width of the waterproof and vapor barrier film laid on the bottom side of the building base is equal to the width of the pipeline thermal insulation layer laid on the inner side of the pipeline thermal insulation layer.

[0013] The equal laying width on both sides of the connection position is beneficial to the installation stability of the waterproof and vapor barrier film, and will not cause the waterproof and vapor barrier film to descend or separate from the original position after long-term use due to the gravity bias on one side, thereby improving the durability.

[0014] Further, the iron hoop comprises an iron ring and a screw rod, the iron ring is an elastic circular arc structure with an angle of 270°-360°, two ends of the elastic circular arc structure are respectively provided with a transverse through hole and a threaded hole, the screw rod is arranged in the through hole, the external thread of the screw rod is matched with the internal thread of the threaded hole, and the screw rod is adjustably connected with the iron ring through the threaded hole.

[0015] The adjustable structure of the iron hoop facilitates the adjustment of the connection between the aluminum alloy sheet water cover and the pipeline to a suitable pressing force, and the structure of the iron hoop is convenient for installation and disassembly, and the operation of use and maintenance is convenient.

[0016] Further, the waterproof and vapor barrier film comprises a three-layer structure of PP spun-bonded non-woven fabric, PE high molecular vapor-permeable film and PP spun-bonded non-woven fabric. The PP spun-bonded non-woven fabric mainly enhances the tensile force, static water pressure and protects the PE high molecular vapor-permeable film in the middle layer, and the vapor permeability mainly depends on the PE high molecular vapor-permeable film in the middle layer.

[0017] The spacing between gas molecules is large, and the gas molecules can pass through the air-permeable holes of the waterproof and air-permeable film during diffusion movement. The spacing between liquid molecules is smaller than the spacing of the air-permeable holes, and the liquid molecules cannot pass through the waterproof and air-permeable film under the action of surface tension, that is, the waterproof effect is achieved.

[0018] Further, the sealant used in the gap at the connection between the aluminum alloy plate and the pipeline is any one of a silicone sealant and a polyurethane sealant.

[0019] The sealant used in the gap at the connection between the pipeline and the overhanging structure is a concrete sealant.

[0020] The silicone sealant is a single-component, neutral curing product, has no corrosiveness to metals and coated glass, has high adhesion, high strength, high elongation, high modulus, excellent weather resistance, and the like, and has a service life of 50 years under normal weather conditions; has excellent high and low temperature resistance, and always maintains good strength and elasticity in the range of -40°C to 100°C after curing. It has excellent adhesion to most building materials.

[0021] The polyurethane sealant has high tensile strength, excellent elasticity, wear resistance, oil resistance, and cold resistance, and is widely used as a caulking sealant for buildings, squares, and roads.

[0022] The concrete sealant is mainly an epoxy resin mortar, which is a slurry with high viscosity formed by mixing epoxy resin and quartz sand, and has physical and mechanical properties such as compression resistance and adhesion, which are much better than those of cement-based grouting materials. The reaction and curing of the epoxy resin mortar are mild, and the low heat release peak allows for an operation time of up to 90 minutes (25°C), which is suitable for large-volume grouting; the grouting has no shrinkage after molding, ensuring the need for high-precision installation; it can be in long-term contact with chemicals such as acids, bases, salts, and oils without corrosion. It can be used in harsh physical conditions such as freezing and thawing alternation and vibration under pressure in the range of -80°C to +80°C for a long time without plastic deformation, ensuring the long-term accuracy of the positioning of installed objects; it can resolve any dynamic load that may cause the cement-based grouting layer to burst.

[0023] Further, the upper surface of the building base is covered with a waterproof and thermal insulation layer.

[0024] The upper surface of the overall structure of the building base is covered with a large area of waterproof and thermal insulation treatment to avoid energy loss due to heat exchange of the building base itself.

[0025] Further, the aluminum alloy plate is a sheet metal profile structure, and the aluminum alloy plate is coated with an anodized layer or an anti-corrosion spray coating.

[0026] Sheet metal profile structure reduces the cost of procurement, and construction is simple and convenient; anodic oxidation or corrosion-resistant spraying enhances the corrosion resistance and oxidation resistance of the aluminum alloy plate, and improves the durability of the roof node.

[0027] Further, the pipeline thermal insulation layer comprises three layers arranged in sequence from near to far along the distance from the pipeline: a thermal insulation layer, a protective layer, and a waterproof layer.

[0028] Further, the thermal insulation layer is made of expanded perlite, expanded vermiculite, diatomite or asbestos, or thermal insulation forming material: thermal insulation tile, which is closely laid against the outer wall of the pipeline.

[0029] The pipeline thermal insulation layer is a layer structure wrapped around the pipeline that can play a role in thermal insulation and heat insulation, wherein the main role of the thermal insulation layer is to reduce heat loss, and the thermal insulation layer is composed of materials with a small thermal conductivity coefficient. The outer surface of the thermal insulation layer is the protective layer, which protects the thermal insulation layer, and the protective layer is generally made of a mixture of asbestos fibers and cement to form an asbestos cement shell. The outer surface of the protective layer is the waterproof layer, which prevents moisture from entering the thermal insulation layer. The waterproof layer is often made of oil felt, iron sheet or brushed oil glass cloth.
