Description

Technical Field

[0001] The present invention relates to a construction method for an energy-saving and heat-insulating wall and an energy-saving and heat-insulating wall thereof. Background Art

[0002] In recent years, the country has vigorously promoted ultra-low energy consumption and nearly zero energy consumption buildings, accelerated the development of new building industrialization, and actively implemented the actions of carbon peak and carbon neutrality in the building field.

[0003] For the outer envelope system of the frame structure, aerated concrete blocks or slabs are generally used for on-site masonry, and then the inner / outer insulation layer is constructed by a combination of adhesion and anchoring. The construction efficiency is low, the site is dirty and messy, the labor consumption is large, and it does not have the characteristics of building industrialization. Generally, the outer envelope system considers increasing the thickness of the insulation layer and heat insulation bridge-breaking measures to meet higher-level energy-saving requirements. In addition, the inner insulation system cannot solve the heat bridge problems of beams, columns and other parts, and the energy saving cannot meet the standards; and more and more provinces and cities across the country have prohibited the practice of combining outer insulation adhesion and anchoring. If aerated concrete blocks or slabs are still used for on-site masonry, there will be no available insulation practice. Summary of the Invention

The integrated thermal insulation and keel integrated unit component includes a keel framework, an A-level thermal insulation board, and a connector. The keel framework includes a horizontal keel, a bottom keel, a head plate, and a plurality of vertical keels. The horizontal keel, the bottom keel, and the head plate are all connected to the plurality of vertical keels, and the head plate and the bottom keel are respectively located at the top and bottom of the vertical keels.

[0084] The descriptions of the following embodiments refer to the accompanying drawings to exemplify specific embodiments in which the present invention can be implemented.

[0085] As Figures 1 to 12As shown in the figure, this embodiment discloses a construction method for an energy-saving and heat-insulating wall. This construction method for the energy-saving and heat-insulating wall is used for fabricating the energy-saving and heat-insulating wall, which includes an integrated heat-insulation and keel integrated unit member 1, a top keel 2, a supplementary Class A heat-insulation board 3, a filled heat-insulation layer, and a base wall. The construction method for the energy-saving and heat-insulating wall comprises the following steps: Step S1, detachably connect a hoisting frame 20 to the integrated heat-insulation and keel integrated unit member 1; Step S2, hoist the hoisting frame 20 to hoist the integrated heat-insulation and keel integrated unit member 1 into position; Step S3, temporarily connect with a diagonal brace to the integrated heat-insulation and keel integrated unit member 1; Step S4, remove the hoisting frame 20; Step S5, connect the top keel 2 to the top of the integrated heat-insulation and keel integrated unit member 1; Step S6, connect both the bottom of the integrated heat-insulation and keel integrated unit member 1 and the top keel 2 to the building beam-column part 10; Step S7, install the supplementary Class A heat-insulation board 3 at the joint between the top of the integrated heat-insulation and keel integrated unit member 1 and the building beam-column part 10; Step S8, spray the filled heat-insulation layer on the inner side surface of the integrated heat-insulation and keel integrated unit member 1; Step S9, construct and install the base wall on the inner side surface of the filled heat-insulation layer.

[0086] Install and set the integrated heat-insulation and keel integrated unit member 1 on the building beam-column part 10. Since the structural beam 101 and the structural column 102 on the building beam-column part 10 have been constructed in advance, the integrated heat-insulation and keel integrated unit member 1 cannot adopt the traditional vertical hoisting method from top to bottom; by providing an eccentric hoisting frame 20 at the top of the integrated heat-insulation and keel integrated unit member 1, the suspension point and the suspension cable are both located outside the integrated heat-insulation and keel integrated unit member 1, that is, after the integrated heat-insulation and keel integrated unit member 1 is in place, the suspension cable is still outside the building, realizing the hoisting-in-place direction in the horizontal direction (from far to near).

[0087] Connect the top keel 2 to the top of the integrated heat-insulation and keel integrated unit member 1; install the supplementary Class A heat-insulation board 3 at the joint between the top of the integrated heat-insulation and keel integrated unit member 1 and the building beam-column part 10; the use of the supplementary Class A heat-insulation board 3 and the top keel 2 ensures the structural stability and improves the heat-insulation effect of the energy-saving and heat-insulating wall. At the same time, the filled heat-insulation layer is integrally sprayed before the on-site construction of the base wall, and the heat-insulation integrity is good.

[0088] In this embodiment, the space reserved between the integrated heat-insulation and keel integrated unit member 1 and the upper structural beam 101 is filled by the supplementary Class A heat-insulation board 3 later. The supplementary connecting piece 31 passes through the supplementary Class A heat-insulation board 3 from the outer side surface of the supplementary Class A heat-insulation board 3 and is connected to the top keel 2, so that the supplementary Class A heat-insulation board 3 fills the space between the integrated heat-insulation and keel integrated unit member 1 and the non-removable heat-insulation formwork 103, and the heat-insulation effect is good.

[0089] In this embodiment, the integrated thermal insulation and keel integrated unit member 1 includes an A-level thermal insulation board 11, a keel framework 12, and a connecting member 13. The keel framework 12 includes a horizontal keel 122, a bottom keel 123, a head plate 124, and a plurality of vertical keels 121. The horizontal keel 122, the bottom keel 123, and the head plate 124 are all connected to the plurality of vertical keels 121, and the head plate 124 and the bottom keel 123 are respectively located at the top and bottom of the vertical keel 121.

[0090] Before step S1, the following steps are also included: Step S10, assembling the vertical keel 121, the horizontal keel 122, the bottom keel 123, and the head plate 124 in a processing factory to form the keel framework 12; Step S20, opening bottom holes at the installation layout positions where the connecting member 13 needs to be installed in the vertical keel 121 and the A-level thermal insulation board 11 in the keel framework 12; Step S30, screwing the connecting member 13 into the bottom holes from the outside of the A-level thermal insulation board 11 so that the outside of the keel framework 12 is connected to the A-level thermal insulation board 11.

[0091] The A-level thermal insulation board 11 and the keel framework 12 are integrated in the factory and transported to the site and directly hoisted into place in the form of the integrated thermal insulation and keel integrated unit member 1. The installation is convenient, fast, and efficient, realizing the synchronous construction of thermal insulation and enclosure. At the same time, the overall structural strength of the keel framework 12 is high. It is the load-bearing component of the integrated thermal insulation and keel integrated unit member 1. The connecting member 13 is arranged from the outside to the inside from the outside of the A-level thermal insulation board 11 and is connected to the keel framework 12, so that the A-level thermal insulation board 11 is connected and fixed to the keel framework 12 through the connecting member 13, effectively ensuring the structural strength of the integrated thermal insulation and keel integrated unit member 1, avoiding the risk of falling off, being safer and more reliable, and realizing the high strength and not being easily deformed of the integrated thermal insulation and keel integrated unit member 1.

[0092] In this embodiment, as Figure 1 shown, the width of the integrated thermal insulation and keel integrated unit member 1 is generally the maximum finished product size of the A-level thermal insulation board 11 (generally 1.2 m), and the height can be the full storey height. After being transported to the site, they are hoisted into place one by one in the form of the integrated thermal insulation and keel integrated unit member 1.

[0093] In other embodiments, the integrated thermal insulation and keel integrated unit component 1 can also be a full-span wall between adjacent structural columns 102 in the beam-column part 10 of a building (the column span can reach 8-9m in a general frame structure). In this method, the size of the integrated thermal insulation and keel integrated unit component 1 is larger. After being transported to the site, it is hoisted into place at one time, that is, the installation of the full-span wall is completed. Processing in the factory can ensure flatness and precision, eliminating the on-site assembly process, and also avoiding problems such as time-consuming on-site adjustment of the flatness between each integrated thermal insulation and keel integrated unit component 1 and handling joints, further improving the construction efficiency and construction precision.

[0094] As Figure 1 , Figure 3 and Figure 8 shown, the integrated thermal insulation and keel integrated unit component 1 further includes a support bracket 14. Between step S10 and step S20, the following steps are also included: Step S11, install the support bracket 14 on the outer side of the bottom of the keel framework 12; Step S12, place the Class A thermal insulation board 11 on the support bracket 14, and the Class A thermal insulation board 11 and the keel framework 12 are placed correspondingly.

[0095] Due to the need for hoisting, a top keel 2 is used for butt joint connection in the reserved space at the top of the integrated thermal insulation and keel integrated unit component 1. After that, the integrated thermal insulation and keel integrated unit component 1 is fixed to the upper structural beam 101 through the top keel 2. The Class A thermal insulation board 11 is arranged on the outer side of the keel framework 12. The vertical keels 121 in the keel framework 12 are pre-drilled with bottom holes according to the layout drawing of the connecting pieces 13, and then the connecting pieces 13 are screwed into the bottom holes until one complete thread completely passes through the vertical keels 121. The support bracket 14 and the keel framework 12 are integrated into one body. The Class A thermal insulation board 11 is further effectively fixed through two measures of the support bracket 14 and the connecting pieces 13, greatly improving the safety and stability of the integrated thermal insulation and keel integrated unit component 1.

[0096] Among them, the support bracket 14 is used to support the outer Class A thermal insulation board 11 and bear the self-weights of the Class A thermal insulation board 11, the plastering layer 4 and the finishing layer. The support bracket 14 is provided with a punching structure, which is convenient for nailing to fix the Class A thermal insulation board 11 and prevent displacement during hoisting and use.

[0097] In step S1, one end of the lifting frame 20 is connected to the head plate 124, and the other end of the lifting frame 20 extends outward along the direction away from the building beam-column part 10, so that the lifting frame 20 is eccentrically arranged on the integrated thermal insulation and keel integrated unit member 1. The lifting frame 20 is fixed to the top of the integrated thermal insulation and keel integrated unit member 1 by bolts. The extending direction of the lifting frame 20 is perpendicular to the height direction of the integrated thermal insulation and keel integrated unit member 1, so that the lifting frame 20 is eccentrically arranged on the integrated thermal insulation and keel integrated unit member 1. At the same time, the installation and disassembly are very convenient and can be reused.

[0098] Wherein, the lifting frame 20 is provided with a lifting buckle 201, which is convenient for hoisting through the lifting buckle 201. The shape of the lifting frame 20 is mountain-shaped, and both sides of the lifting frame 20 are respectively connected to the two ends of the top of the integrated thermal insulation and keel integrated unit member 1.

[0099] In step S6, it specifically includes the following steps: Step S61, the bottom keel 123 is connected to the building beam-column part 10 by chemical anchor bolts; Step S62, a rigid spacer 30 for adjusting the joint thickness and top elevation is arranged between the structural beam 101 on the building beam-column part 10 and the top keel 2; Step S63, the top of the top keel 2 is connected to the building beam-column part 10 by chemical anchor bolts. The bottom keel 123 and the top keel 2 are respectively connected to the lower structural beam 101 and the upper structural beam 101 by chemical anchor bolts, and the connection strength is high, further improving the stability. At the same time, the structural connection is made more stable and reliable through the rigid spacer 30.

[0100] As Figure 8 shown, in step S6, a notch is reserved at the bottom of the building beam-column part 10, and the notch is located at the top of the non-removable thermal insulation formwork 103 outside the lower structural beam 101. A protrusion is reserved at the bottom of the integrated thermal insulation and keel integrated unit member 1, and the protrusion is located at the bottom of the A-level thermal insulation board 11. The protrusion and the notch cooperate with each other to form another tongue-and-groove waterproof structure, increasing the seepage path and ensuring the waterproof effect of the bottom joint together with the waterproof material.

[0101] As Figure 10 shown, the side of the A-level thermal insulation board 11 is closely joined with the non-removable thermal insulation formwork 103 of the cast-in-place column. A waterproof coating is filled between the integrated thermal insulation and keel integrated unit member 1 and the structural column 102.

[0102] In step S9, it specifically includes the following steps: The base wall is connected to the building beam-column part 10 and / or the keel framework 12. Thereby effectively strengthening the connection strength and greatly improving the safety and stability of the energy-saving and heat-insulating wall.

[0103] In step S2, it specifically includes the following steps: Step S21, hoist the integrated thermal insulation and keel integrated unit member 1 by the hoisting frame 20; Step S22, after leveling the integrated thermal insulation and keel integrated unit member 1, hoist it quickly and steadily to the front of the installation position and slowly approach it from far to near; Step S23, pull the bottom of the integrated thermal insulation and keel integrated unit member 1 into place; Step S24, pull the top of the integrated thermal insulation and keel integrated unit member 1 into place; Step S25, calibrate the integrated thermal insulation and keel integrated unit member 1. Thus, the hoisting and calibration of the integrated thermal insulation and keel integrated unit member 1 are realized, and the installation is convenient, fast and efficient.

[0104] As Figures 1 to 10 shown, this embodiment discloses an energy-saving thermal insulation wall, which is processed and manufactured by using the construction method of the energy-saving thermal insulation wall as described above. The integrated thermal insulation and keel integrated unit member 1 includes an A-level thermal insulation board 11, a keel framework 12 and a connecting member 13. The keel framework 12 includes a horizontal keel 122, a bottom keel 123, a head plate 124 and a plurality of vertical keels 121. The horizontal keel 122, the bottom keel 123 and the head plate 124 are all connected to the plurality of vertical keels 121, and the head plate 124 and the bottom keel 123 are respectively located at the top and bottom of the vertical keels 121. The inner side of the A-level thermal insulation board 11 is connected to the keel framework 12 through the connecting member 13. The filling thermal insulation layer is located between the base wall and the inner side of the A-level thermal insulation board 11, and the filling thermal insulation layer is connected to the keel framework 12. The base wall is connected to the building beam-column part 10 and / or the keel framework 12. The top keel 2 is connected to the head plate 124, and the supplementary A-level thermal insulation board 3 is arranged on the A-level thermal insulation board 11 and connected to the top keel 2.

[0105] Integrate and produce the integrated thermal insulation and keel integrated unit member 1 with the A-level thermal insulation board 11, the keel framework 12, the connecting member 13 and the support bracket 14 in the factory, transport it to the site and directly hoist it into place in the form of the integrated thermal insulation and keel integrated unit member 1. The installation is convenient, fast and efficient, realizing the synchronous construction of thermal insulation and enclosure; at the same time, the structural strength is high, avoiding the risk of falling off, and greatly improving the safety and stability of the energy-saving thermal insulation wall.

[0106] The structural design with the filled thermal insulation layer placed between the base wall and the Class A thermal insulation board 11 provides the possibility of using non-flammable organic thermal insulation materials with better thermal insulation effects, without fire safety problems, which can further reduce the overall thickness of the energy-saving thermal insulation wall and increase the usable area within the building. The combined application of the Class A thermal insulation board 11 and the filled thermal insulation layer meets the energy-saving and thermal insulation requirements of the energy-saving thermal insulation wall on the premise of ensuring fire safety. At the same time, the structural position relationship between the Class A thermal insulation board 11 and the filled thermal insulation layer avoids the common drawbacks of internal thermal insulation (such as condensation, mildew, and staggered floors with beam-column parts) that occur when using internal and external combined thermal insulation to achieve energy-saving effects. It realizes firm structural connection, fire safety of materials, good thermal insulation effect, obvious energy-saving effect, and convenient construction. Among them, the base wall is a keel-covered panel, generally cement fiber board, gypsum board, calcium silicate board, etc.

[0107] The filled thermal insulation layer is used to fill the gaps of the keel framework 12, generally a Class B thermal insulation material. The filled thermal insulation layer can cover the keel framework 12, or it can also be embedded in the keel framework 12. When the thickness of the filled thermal insulation layer is less than the thickness of the keel framework 12, the filled thermal insulation layer will be completely embedded into the keel framework 12; the thickness of the filled thermal insulation layer can also be greater than or equal to the thickness of the keel framework 12, so that part of the structure of the filled thermal insulation layer is embedded into the keel framework 12, and the filled thermal insulation layer completely covers the inner side surface of the keel framework 12.

[0108] The filled thermal insulation layer includes but is not limited to one or more of graphene thermal insulation materials, molded polystyrene boards, extruded polystyrene boards, graphite molded polystyrene boards, graphite extruded polystyrene boards, polyurethane thermal insulation materials, and rock wool thermal insulation materials. Thus, it improves the overall thermal insulation effect of the finally formed wall to meet the energy-saving requirements of the energy-saving thermal insulation wall. Among them, due to the forming process, sprayed polyurethane foam is the best for the filled thermal insulation layer.

[0109] The energy-saving thermal insulation wall also includes a plastering layer 4. The plastering layer 4 includes anti-cracking mortar and alkali-resistant fiberglass mesh cloth. The anti-cracking mortar is connected to the outer side surface of the Class A thermal insulation board 11, and the alkali-resistant fiberglass mesh cloth is arranged in the anti-cracking mortar. The anti-cracking mortar is used for leveling and protection, and the alkali-resistant fiberglass mesh cloth arranged in the anti-cracking mortar can enhance the overall structural firmness of the plastering layer 4 and improve the safety and stability of the energy-saving thermal insulation wall.

[0110] A decorative layer is provided on the outer surface of the Class A thermal insulation board 11 and / or the base wall. The added decorative layer is used to protect the wall, beautify the building, and meet the usage requirements.

[0111] In one embodiment, the material of the Class A thermal insulation board 11 is a Class A fireproof thermal insulation material. The Class A fireproof thermal insulation material effectively ensures the fireproof performance and thermal insulation performance of the energy-saving thermal insulation wall, so that there is no need to additionally composite inorganic plates to enhance its strength and fireproof performance. Among them, because the national standard stipulates that Class A thermal insulation materials should be used for external wall thermal insulation (otherwise, a fireproof isolation belt needs to be set, which is troublesome in construction), it is generally a finished rigid plate, which is connected and fixed by the connector 13 and the keel framework 12.

[0112] In another embodiment, the material of the Class A thermal insulation board 11 is a graphene thermal insulation material. It effectively ensures the thermal insulation performance and fireproof performance of the energy-saving thermal insulation wall, and greatly improves the safety and stability of the energy-saving thermal insulation wall.

[0113] In other embodiments, the Class A thermal insulation board 11 includes a Class A fireproof and flame-retardant material and a Class B high-efficiency thermal insulation material that are connected to each other. The composite of the two materials with fire resistance ratings of Class A and Class B respectively utilizes the Class A fireproof and flame-retardant Class A fireproof and flame-retardant material and the excellent thermal insulation performance of the Class B Class B high-efficiency thermal insulation material, which can not only meet the energy-saving requirements, but also has a thinner thickness, is economical and environmentally friendly. Among them, the Class A fireproof and flame-retardant material can be connected to the outer side of the Class B high-efficiency thermal insulation material, and the inner side of the Class B high-efficiency thermal insulation material is connected to the keel framework 12, so as to realize connecting the Class A thermal insulation board 11 to the outer side of the keel framework 12. The Class A fireproof and flame-retardant material can also cover the Class B high-efficiency thermal insulation material, and the specific connection position and connection method are not limited.

[0114] The material of the connector 13 is metal. The metal connector 13 is used to connect with the Class A thermal insulation board 11 and the keel framework 12, further ensuring the structural connection strength, avoiding the risk of falling off, and being safer and more reliable. The outer surface of the connector 13 is wrapped with a heat-insulating sleeve. The strength and service life of the connector 13 can meet the design requirements. At the same time, the connector 13 has a good heat-insulating effect through the heat-insulating sleeve, effectively avoiding the existence of the cold and heat bridge phenomenon. Among them, the connector 13 is generally a self-tapping screw with a nylon wrap, which is convenient for installation and only needs to bear the out-of-plane load of the Class A thermal insulation board 11, the plastering layer 4 and the finishing layer. The nylon wrap is a heat bridge breaking measure to block the heat transfer path at the connector 13, and it can also be wrapped with other materials. The connector 13 is an anchoring connector 13.

[0115] The materials of the keel framework 12 and the support bracket 14 can both be stainless steel. This prevents the keel framework 12 and the support bracket 14 from rusting, and further improves the safety and stability of the energy-saving thermal insulation wall.

[0116] Of course, the materials of the keel framework 12 and the supporting bracket 14 can also be fiber-reinforced composite materials. That is to say, the materials of the keel framework 12 and the supporting bracket 14 can both be high-strength materials such as fiber-reinforced polymer / plastic (FRP for short), because the FRP has a lower thermal conductivity than metal and less heat loss, making the keel framework 12 and the supporting bracket 14 have good heat insulation effects to prevent the keel framework 12 and the supporting bracket 14 from generating thermal bridge effects.

[0117] The materials of the keel framework 12 and the supporting bracket 14 are both metals, and the outer surfaces of the metals have rust-proof layers. Through the rust-proof layers, rust-proof treatment can be achieved on the outer surfaces of the keel framework 12, so that the keel framework 12 and the supporting bracket 14 made of metal materials do not rust under the daily construction conditions, greatly improving the safety and stability of the energy-saving and heat-insulating wall.

[0118] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
