Description

Technical Field

[0001] The present invention relates to the technical field of heat insulation and energy conservation construction of buildings, and specifically to a heat insulation and energy conservation construction method for the foundation of a roof-type solar power generation steel structure.

Background Art

[0002] With the increasing global energy crisis, zero-carbon buildings have become one of the important solutions. A zero-carbon building is a building in which, in a situation where it does not consume energy such as coal, oil, and electricity, the annual energy consumption is provided entirely by renewable energy generated on the site. Its main feature is that, in addition to emphasizing the passive energy conservation design of the surrounding protection structure of the building, it is to convert the energy demand of the building into renewable energy such as solar energy, wind energy, shallow geothermal energy, and biomass energy, and find an optimal solution for the harmonious coexistence among humans, buildings, and the environment.

[0003] In the roof structure, the heat insulation of the solar power generation steel structure plays an important role in the heat insulation performance of the entire zero-carbon building. Since the roof is the part of the building that is most vulnerable to heat loss and moisture penetration, selecting an appropriate heat insulation and energy conservation construction method for the roof is important for reducing energy consumption. However, in conventional zero-carbon buildings, there is no good solution to the technical problems of the foundation heat insulation of the solar power generation steel structure, so there are technical defects in the zero-carbon roof heat insulation and energy conservation construction method.

[0004] Therefore, how to provide a heat insulation and energy conservation construction method for the foundation of a roof-type solar power generation steel structure, improve the heat insulation construction quality of the roof-type solar power generation steel structure, improve the on-site construction efficiency, effectively shorten the construction period, improve the overall construction quality, and ensure the technical requirement of heat insulation and energy conservation of zero-carbon buildings is an urgent problem for those skilled in the art to solve.

Summary of the Invention

[0005] In view of this, the present invention provides an energy-saving insulation construction method for the foundation of a roof-type solar power generation steel frame structure in order to solve the above technical problems.

[0006] To achieve the above objective, the present invention employs the following technical approach.

[0007] The energy-saving insulation construction method for the foundation of a steel frame structure for roof-mounted solar power generation is as follows: Step S1 involves pouring concrete into the roof of the building, Step S2 involves pouring insulating mortar into the base of the steel structural column and fixing the steel structural column to the concrete foundation with bolts, Step S3 involves constructing the first waterproofing layer of the foundation around the perimeter of the concrete foundation, After the first waterproofing layer of the foundation is completed, step S4 is performed to cover the outside of the first waterproofing layer of the foundation with the foundation insulation layer, Step S5 involves installing the second waterproofing layer of the foundation on the outside of the foundation insulation layer, Step S6 involves performing insulation work on the base of the steel structural column, This includes S7, which is used for surface layer construction.

[0008] The beneficial effects of the above technical proposal are as follows: The energy-saving insulation construction of the foundation of the solar power generation steel frame structure is divided into two parts: insulation construction of the concrete foundation and insulation construction of the column bases of the steel frame structure columns. Two layers of waterproofing are installed on the concrete foundation, and an insulating layer is installed between the two waterproofing layers, thereby effectively guaranteeing the insulation and waterproofing effect of the concrete foundation. Insulating mortar is filled into the column bases of the steel frame structure columns, effectively creating overlapping connections between the steel frame structure columns and the steel beams of the roof through thermal bridging. In addition, a column base insulation layer is installed on the outer perimeter of the column bases of the steel frame structure columns, effectively guaranteeing the insulation effect of the column bases of the steel frame structure columns. This is safe, effective, easy to implement, guarantees the technical requirements of energy-saving insulation for zero-carbon buildings, accelerates construction progress, and reduces construction costs.

[0009] Preferably, in step S1, anchor bolts are fixed within the concrete base, with their threaded ends exposed from the upper surface of the concrete base, and embedded steel plates, which are fixed to the upper surface of the concrete base, are fixed to the threaded ends of the anchor bolts. The steel structural columns are fixed with the embedded steel plates and anchor bolts, resulting in a simple and reliable connection.

[0010] In step S1, after the installation of the steel structural column is complete, anchor bases are driven into the upper surface of the concrete foundation to enclose the column bases of the steel structural column. The anchor bases enclose the column bases of the steel structural column on the upper surface of the concrete foundation, improving the connection effect between the steel structural column and the concrete foundation, ensuring that the steel structural column has sufficient anchoring force, and preventing tilt failure of the steel structural column.

[0011] Preferably, in step S2, the insulating mortar is Grade A water-repellent expandable slag insulating mortar, and after the pouring of the insulating mortar is complete, the lower end surface of the steel structural column is attached to the upper surface of the embedded steel plate and fastened with anchor bolts and nuts. Baffles are fixed circumferentially along the cavity of the column base of the steel structural column, pouring holes are made in the bottom surface of the steel structural column, insulating mortar is poured into the steel structural column through the pouring holes, and the steel structural column is lifted after the insulating mortar has hardened. Grade A water-repellent expandable slag insulating mortar is an inorganic insulating mortar manufactured by pre-mixing and drying agitation after adding a water-repellent agent, an inorganic gelling material and several types of external additives, with vitrified bead lightweight aggregate as the main raw material. Grade A water-repellent expandable slag insulation mortar has low thermal conductivity and superior insulation properties, as well as excellent sound insulation and fire resistance. Its flammability is Grade A, and it can withstand temperatures below 1000°C. It overcomes the shortcomings of conventional organic insulation materials, such as being highly flammable and generating toxic gases at high temperatures. Furthermore, it has low construction costs, is greener and more environmentally friendly, has a long service life, and can withstand weathering for up to 70 years, ensuring that the insulation within steel structural columns and the roof have equivalent lifespans.

[0012] Preferably, in step S3, the first waterproof layer of the foundation and the first waterproof layer of the roof are constructed synchronously, and when the roof waterproof layer is constructed, the first waterproof layer of the foundation is bonded to the periphery of the concrete foundation and anchor base, and the first waterproof layer of the foundation includes one layer of alkali-resistant aluminum foil-faced glass fiber self-adhesive modified asphalt moisture-proof coil material that extends upward to the connection point between the anchor base and the steel structural column.

[0013] Preferably, in step S4, the foundation insulation layer is installed after the first waterproof layer of the foundation is completed, the foundation insulation layer and the roof insulation layer are installed synchronously, the foundation insulation layer is made by joining extruded polystyrene boards, and multiple extruded polystyrene boards are fixed to the outer perimeter of the first waterproof layer of the foundation.

[0014] Preferably, in step S5, the second waterproof layer of the foundation is bonded to the outer perimeter of the foundation insulation layer, and the second waterproof layer of the foundation and the second waterproof layer of the roof are installed synchronously, and the second waterproof layer of the foundation includes one layer of double-sided self-adhesive polymer-modified asphalt waterproof coil material and one layer of single-sided self-adhesive polymer-modified asphalt waterproof coil material, which are bonded sequentially to the outside of the foundation insulation layer.

[0015] The beneficial effects of the above technical proposal are as follows: Two layers of waterproofing are installed on both sides of the foundation insulation layer, and the first waterproofing layer, insulation layer, and second waterproofing layer of the foundation are constructed in sync with the first waterproofing layer, roof insulation layer, and second waterproofing layer of the roof, respectively, thereby ensuring the integrity of the connection between the roof and the concrete foundation and ensuring an overall energy-saving effect through insulation between the roof, the concrete foundation, and the anchor base.

[0016] Preferably, in step S5, after the construction of the second waterproof layer of the foundation is completed, an insulating mortar is applied to the outside of the single-sided self-adhesive polymer-modified asphalt waterproof coil as a waterproof protective layer. The waterproof protective layer completely encloses the second waterproof layer and prevents damage to the second waterproof layer due to prolonged weather from adversely affecting the thermal insulation and waterproofing properties of the concrete foundation and anchor base.

[0017] Preferably, in step S6, after the construction of the second waterproof layer of the foundation is completed, insulation is performed on the base of the steel structural column, and the outer circumference of the base of the steel structural column is wrapped with steel wire rock wool. The steel wire rock wool is tied and fixed to the outer wall of the base of the steel structural column with galvanized steel wire, extending downwards to cover the upper surface of the anchor base. After the foundation insulation is completed, insulation is performed on the steel structural column, and the outer circumference of the base of the steel structural column is wrapped with steel wire rock wool. The steel wire rock wool extends upwards from the upper surface of the anchor base to the steel structural column, and a method is adopted in which the entire steel wire rock wool is cut and joined together to tightly pack the inside without any gaps, which effectively guarantees the insulation performance of the steel structural column. Combined with the insulating mortar inside the base of the steel structural column, it guarantees overlapping connection by thermal bridging between the steel structural column and the roof steel beam, and ensures overall insulation performance between the roof and the steel structural column.

[0018] Preferably, in step S7, after the binding of the steel wire rock wool is completed, a surface layer coating is performed on the outer periphery of the steel wire rock wool, and the surface layer coating includes the application of a non-combustible insulation slurry and decorative fabric to the outer surface of the steel wire rock wool in sequence. By using water-resistant putty as the non-combustible insulation slurry and applying it to the outer surface of the steel wire rock wool, the steel wire rock wool can be protected from erosion and damage, and by applying decorative fabric, the aesthetic appearance of the column base of the steel structural column can be improved.

[0019] As can be seen from the above technical proposal, compared to conventional technology, the present invention provides an energy-saving construction method for insulating the base of roof-type solar power generation. In line with the characteristics of zero-carbon building construction, it installs two layers of waterproofing on both sides of the concrete base insulation layer and constructs them in sync with the roof to ensure integrity and efficient insulation between the roof and the concrete base. It also fills the inside of the column base of the steel structural column with insulating mortar and wraps the outer perimeter with steel wire rock wool to ensure the insulation of the column base of the steel structural column and the overlapping connection with the steel beams of the roof through thermal bridging, effectively improving the overall insulation between the steel structural column and the roof. The energy-saving insulation construction method provided by the present invention is safe, effective, and easy to implement, guarantees the technical requirements of energy-saving insulation for zero-carbon buildings, meets the construction progress requirements, improves the overall insulation construction quality between the roof, concrete base and steel structural column, improves on-site construction efficiency, the construction method is easy to operate, effectively shortens the construction period, guarantees the technical requirements of energy-saving insulation for zero-carbon buildings, and yields good social and economic benefits.
