A core-tube thermal break composite wall system for low-energy buildings and its construction method

Abstract

A core-tube thermal break composite wall system and construction method for low-energy buildings includes a concrete fireproof shear protection layer, precast insulation panels, and a floor slab core tube system. The core tube system comprises a concrete main structural layer, a portal frame system and a curtain wall system installed within the concrete fireproof shear protection layer, precast insulation panels, and the concrete main structural layer. This invention utilizes a combination of portal frame structure, curtain wall structure, and concrete shear wall structure to form a core-tube seismic-resistant external wall thermal break insulation system, improving the overall building's seismic resistance and other safety performance. Because it employs a concrete fireproof shear protection layer with shear wall function, it eliminates the need for floor slab overhangs and achieves complete insulation and thermal break treatment at the outer ends of the floor slab, thus improving building energy efficiency. It is applicable to low-rise, multi-story, and high-rise low-energy buildings.

Description

Technical Field

[0001] This invention relates to the field of building insulation wall engineering technology, and in particular to a core tube type thermal break composite wall system for low-energy buildings and its construction method. Background Technology

[0002] Safety Impact: The existing low-energy integrated insulation building technology has a fragile connection between the concrete fireproof protective layer, precast insulation board, and shear wall of the main concrete structure. This makes it easy for the concrete fireproof protective layer and insulation layer to fall off or crack, causing significant safety hazards. Because of the weak connection, the external wall insulation system has poor seismic performance. In the event of an earthquake, the entire concrete fireproof protective layer and insulation layer may fall off, causing even greater damage to life and property.

[0003] Energy-saving impact: Existing low-energy integrated structural insulation building technology has too many connecting parts between the concrete fireproof protection layer, insulation layer and structural layer. Most of the connecting parts are made of metal, which causes a large number of cold bridges on the building exterior walls, seriously reducing the energy-saving effect of the exterior walls.

[0004] Existing low-energy building technologies suffer from poor window insulation and excessive thermal bridges, failing to meet the energy-saving requirements of low-energy buildings. Even if they can barely meet the energy-saving requirement of 90% or higher, it requires additional material and labor costs for window thermal break treatment and passive windows, resulting in very high construction costs.

[0005] Some existing low-energy integrated building technologies for structural insulation have adopted floor slab cantilever technology. Although this solves the risk of fireproof protection layer and insulation layer falling off, it also makes it impossible to properly handle insulation and cold bridges at the outer end of the floor slab, which seriously reduces the building's energy-saving effect.

[0006] Existing low-energy integrated structural insulation technology for buildings does not thoroughly address the insulation and cold bridge treatment of the parapet wall on the top floor, and the treatment methods are very complex, resulting in high costs and poor energy-saving effects.

[0007] Existing low-energy integrated structural insulation technology requires building exterior wall air conditioning panels and downpipes to be embedded in the main shear wall, and insulation problems and cold bridges cannot be completely solved, resulting in a serious reduction in building energy efficiency.

[0008] The existing low-energy integrated thermal insulation building technology uses prefabricated insulation panels that are prone to shifting during concrete pouring, which affects the quality of the project.

[0009] Therefore, current low-energy integrated structural insulation building technologies make it difficult for buildings to achieve an overall energy saving of 90% or more. Even if it were possible, the cost would be enormous.

[0010] Given the current demands of the construction industry for high-rise buildings, their seismic performance is of paramount importance. Internationally, the mainstream structural form widely adopted for super high-rise buildings is the core tube structure. This structure uses a central core tube composed of densely packed reinforced concrete columns, forming an outer frame and inner tube structure together with the outer frame, all constructed of reinforced concrete. Summary of the Invention

[0011] The technical problem solved by this invention is to provide a new type of thermal insulation wall structure suitable for high-rise buildings. Through structural adjustment, the insulation and structure are integrated, and the common problems of cracking and falling off of the concrete fireproof protective layer on the exterior wall are completely solved. This reduces the huge post-treatment costs of thermal bridging and reduces the safety hazards of high-rise buildings.

[0086] Beneficial effects

[0087] 1. This invention utilizes a portal frame structure and curtain wall structure combined with a concrete shear wall structure to form a core-tube seismic-resistant external wall thermal insulation system. This invention improves the safety performance (it will never detach), seismic performance, and overall building safety performance, including seismic resistance. It completely solves the safety hazards associated with the use of existing low-energy building technologies in high-rise buildings.

[0088] 2. By adding vertical and horizontal round or square tubes combined with wire mesh to the outside of the precast insulation panels that integrate structural insulation into the building, the outer concrete fireproof shear protection layer functions as a shear wall, forming a concrete shear wall-type fireproof shear protection layer. Horizontal connecting rods penetrating the precast insulation panels can be made of square tubes, round steel, or threaded steel, connecting the vertical supports on the outside of the precast insulation panels, the precast insulation panels, and the shear walls of the main building structure. This creates a portal frame-type seismic structure between the concrete shear wall-type fireproof protection layer and the main concrete structural layer. The concrete fireproof shear wall-type protection layer increases the structural stability and seismic performance of the building's external insulation system, eliminates the risk of cracking or detachment in existing external wall insulation systems, and truly integrates the fireproof protection layer, insulation layer, and main building structure. Furthermore, it has the same lifespan as the building, improving the overall seismic performance of the building.

[0089] 3. The number of connecting rods between the vertical supports on the outside of the precast insulation panels and the main concrete structure layer is reduced compared to traditional technology, and thermal break treatment is used, which greatly reduces thermal bridges in the building's exterior wall system and improves the building's energy efficiency.

[0090] 4. No need for floor slab overhangs; the outer ends of the floor slabs are completely thermally broken, improving the building's energy efficiency.

[0091] 5. Energy-saving measures for building exterior windows: Adopting the principle of curtain wall structure, structural columns such as steel profiles are embedded within prefabricated insulation panels. These structural columns are connected to the main concrete structure using thermally broken connectors. If the structural columns are hollow, they are filled with concrete. Steel beams are added above and below the windows and connected to the structural columns to form a steel frame at the window. The windowsill is fixed to the steel frame, creating a thermal break between the windowsill and the building exterior wall, thus increasing the energy-saving effect at the windows. The inner windowsill uses wood panels or inorganic panels with thermal breaks at the connection point with the window. In addition to thermal breaks, the outer windowsill requires drainage treatment.

[0092] 6. The vertical supports installed within the concrete fireproof shear protection layer can still be used as vertical reinforcement for the parapet wall after the main building structure is topped out. Structurally, this solves the problem of the traditional technology of dealing with thermal bridges in parapet walls being too complicated and costly, completely eliminating the bridge at the base of the parapet wall.

[0093] 7. The exterior wall air conditioning panels and downpipes can be anchored to the concrete fireproof shear wall protective layer, without needing to be anchored to the main concrete structural layer. This solves the thermal bridging problem at the connection points between the air conditioning panels and downpipes and the main structure, achieving a complete bridging solution.

[0094] 8. The building's exterior walls, floors, windows, parapet walls, air conditioning panels, downpipe joints, the embedded profiles in the insulation material, the base, and every part of the top floor have been treated with thermal break and insulation, which greatly improves the building's energy efficiency and easily meets the national requirements for low-energy buildings. The energy efficiency standard can be achieved at a rate of 90% or higher at a very low cost.

[0095] 9. Because the vertical support added to the outside of the precast insulation board runs through from the bottom to the top, it plays a role in positioning the built-in insulation board, solving the problem of the insulation board shifting and floating during concrete pouring, and ensuring the quality of the project.

[0096] 10. The window structure is designed to accommodate a double-glazed window sill. In buildings that achieve 90% energy efficiency, the cost of a double-glazed thermal break window system is lower than that of currently used single-glazed passive windows.

[0097] 11. If the horizontal connecting rod of the precast insulation board’s outer vertical support column to the concrete main structure is a round or square tube, it can simultaneously serve as a channel (or through bolt) for the formwork and a top rod, saving labor and auxiliary materials and reducing construction costs.

[0098] 12. Compared with other existing low-energy integrated insulation technologies, this invention comprehensively considers structural stress, construction difficulty, and energy-saving thermal break. After the main building is completed, most of the time and manpower are spent on thermal break treatment. Although this invention adds vertical columns and window sill supports to the traditional technology, it reduces the material and labor costs for thermal break treatment at cantilevered edges, parapet walls, air conditioners, downpipes, etc., thereby reducing the overall cost of low-energy buildings.

[0099] 13. Compared with the prior art, the present invention has a simple structure, uses fewer types of materials, and is convenient to place on site.

[0100] 14. Compared with the existing technology on the construction site, the connection parts of this invention are more convenient and faster to assemble and have an adjustable structure. There will be no repairs or rework during the assembly process. This not only reduces the intensity of manual labor but also greatly improves the construction progress and reduces costs for construction companies.

[0101] 15. This invention can be applied to low-energy buildings of all heights, including low-rise, multi-story, and high-rise buildings. Attached Figure Description

[0123] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0124] It should be explained that the terms "length", "width", "up", "down", "left", "right", etc., which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. The terms "outer side" and "inner side" are based on the space inside the building wall as the inner side and the space outside the building as the outer side. They are only used to simplify the description of the present invention and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as a display of the present invention.

[0125] like Figure 1-3 As shown, a core tube type thermal break composite wall system for low-energy buildings is characterized by: including a concrete fireproof shear protection layer 2, a prefabricated insulation board 1 fixed on one side of the concrete fireproof shear protection layer 2, a floor slab 4 fixedly connected to the other side of the prefabricated insulation board 1, and a core tube system connecting the concrete fireproof shear protection layer 2 and the prefabricated insulation board 1.

[0126] The core tube system includes a concrete main structural layer 3 connected to the other side of the precast insulation board 1; the outer surface of the concrete main structural layer 3 is flush with the end face of the floor slab 4; the concrete fireproof shear protection layer 2 is connected to the upper plane of the floor slab 4; the core tube system also includes a portal system 5 and a curtain wall system 6 disposed within the concrete fireproof shear protection layer 2, the precast insulation board 1, and the concrete main structural layer 3; the portal system 5 connects the concrete fireproof shear protection layer 2, the precast insulation board 1, and the concrete main structural layer 3. The curtain wall system 6 is spaced apart from the portal system 5 and works together with the portal system 5 to resist shear forces. At the same time, the portal system 5 and the curtain wall system 6 serve to connect and fix the concrete fireproof shear protection layer 2, the precast insulation board 1, and the concrete main structural layer 3.

[0127] A low-energy building core-tube thermal break composite wall system is constructed using EPS, XPS, and other insulation materials, steel wire mesh, external structural columns and beams with built-in insulation panels, and internal structural columns and beams embedded in the insulation layer, all made of metal or non-metal (nylon) profiles and various connectors. This invention references external wall insulation technology, concrete shear wall structure technology, portal frame structure technology, curtain wall structure technology, steel-concrete composite pipe technology, and core-tube technology. The portal frame structure and curtain wall structure, combined with the concrete shear wall structure, form the core-tube seismic-resistant structural type of the thermal break insulation system. This invention improves the safety performance (it will never detach), seismic performance, and overall building seismic safety performance of the external wall insulation system. It completely solves the safety hazards associated with the use of existing low-energy building technologies in high-rise buildings.

[0128] like Figure 1-9 As shown, the portal system 5 includes a portal structure that connects the concrete fireproof shear protection layer 2, the precast insulation board 1, and the concrete main structure layer 3 from bottom to top; the portal structure is distributed along the horizontal direction of the concrete main structure layer 3; the portal structure of the upper layer and the portal structure of the lower layer are connected in sequence through the first connecting block 7.

[0129] The portal structure includes a connecting rod 52 installed between the concrete fireproof shear protection layer 2 and the concrete building main structure layer 3, a vertical support column 51 fixedly connected to one end of the connecting rod 52, a first thermal break connecting sleeve 53 connected to the other end of the connecting rod 52, and a steel reinforcement skeleton 31 connected to the first thermal break connecting sleeve 53.

[0130] The steel reinforcement cage 31 is installed from bottom to top within the main concrete building structure layer 3; the vertical support column 51 is installed within the fireproof shear protection layer 2 of the concrete; the first thermal break connecting sleeve 53 is installed within the main concrete building structure layer 3; the connecting rod 52 extends laterally through the precast insulation board 1; each vertical support column 51 is fixedly connected to a transverse support beam; the transverse support beam is installed within the fireproof shear protection layer 2 of the concrete; the vertical support column 51 of the upper layer is connected to the vertical support column 51 of the lower layer through the first connecting plug 7.

[0131] One end of the connecting rod 52 is provided with a metal mesh 54 at intervals and a support 55 fixedly connected between the metal mesh 54 and the prefabricated insulation board 1; the metal mesh 54 is a grid-like sheet with equal spacing of horizontal steel wires 541 and vertical steel wires intersecting and fixed; the horizontal steel wires 541 are vertically fixedly connected to the vertical column 51; the horizontal steel wires 541 are thickened steel wires.

[0132] The bottom vertical support 51 is connected to a bottom support pad 91 at its lower end; the top vertical support 51 is connected to a top support pad 92 at its upper end; both the bottom support pad 91 and the top support pad 92 are fixedly connected to a thermal break gasket 911.

[0133] Vertical columns 51 are added to the outside of the prefabricated insulation board 1 of the building. The vertical columns 51 are round tubes (≥25mm×2.5mm) or square tubes (≥25×25×2.5mm). The distance between two adjacent vertical columns 51 is ≥300mm. The vertical columns 51 can also be threaded steel, round steel, new material steel, etc. (diameter ≥12mm). The distance between two adjacent vertical columns 51 is ≥100mm. The vertical columns 51 are combined with metal mesh 54 (horizontal and vertical steel wire diameter ≥6mm, mesh size ≥50×50mm) to enable the concrete fireproof protection layer of the external insulation material to have the function of shear wall, forming a concrete fireproof shear protection layer with shear wall-type external insulation and fireproof function. The connecting rods 52 that penetrate the insulation material can be made of materials such as round tubes (≥25mm×2.5mm), square tubes (≥25×25×2.5mm), round steel or threaded steel with a diameter ≥12mm, etc.

[0134] According to energy-saving design requirements, the prefabricated insulation board can be made of graphite polystyrene board with a density ≥20 kg / m³ and a thickness ≥250 mm, or extruded polystyrene board with a density ≥35 kg / m³ and a thickness ≥230 mm, etc. The height of the prefabricated insulation board 1 is consistent with the floor height, and the width is determined according to the convenience of construction. The perforations of the connecting rods 52 are prepared. The number and spacing of the connecting rods 52 are determined according to the design requirements, but will be reduced compared to existing technologies. The metal mesh 54 is fixed to the EPS and other insulation materials in the factory by the support body 55 and the connecting rods 52. The vertical column 51 and the horizontal support beam are welded in the factory or on the construction site or connected by connectors. Preferably, the horizontal steel wires 541 on the metal mesh 54 are fixedly connected to the vertical column 51 (which can be connected by clips, welding, threaded connection or special connectors). The connection method is selected according to the on-site construction conditions and construction costs. Since the diameter of the steel wires on the metal mesh 54 is insufficient to meet the shear strength requirements, the transverse steel wires 541, which are the main shear-bearing components, need to be thickened to a diameter capable of bearing the standard shear force. Because the metal mesh 54 is a single unit, the vertical posts 51 can also be connected to the vertical steel wires on the metal mesh 54 without affecting the shear wall's performance. This reduces the need for additional metal components for horizontal support beams, effectively utilizes existing materials, and lowers the requirements for fixing the vertical posts 51, facilitating on-site construction and reducing rework and on-site modifications caused by misalignment during the assembly of prefabricated components and on-site reinforcement.

[0135] The metal mesh 54 is fixed together with the connecting rod 52; the first broken bridge connecting sleeve 53 can be pre-assembled with the connecting rod 52 in the factory, or it can be connected at the construction site.

[0136] The vertical columns 51 of the building from the bottom floor to the top floor are connected by the first connecting block 7, or they can be connected on the construction site by welding. If conditions permit and the vertical columns 51 adopt a round or square tube structure, the inner cavity of the vertical columns 51 of each floor can be filled with concrete. The bottom vertical column 51 is connected to the foundation by the bottom support pad 91, and the top vertical column 51 of the top floor is connected with the top support pad 92.

[0137] Shear force impact: Connecting the vertical columns 51 on the outside of the precast insulation board 1, the precast insulation board, and the shear wall of the main concrete building structure layer together creates a portal frame seismic structure with the fireproof concrete shear wall protective layer and the main concrete structure layer. The fireproof concrete shear wall protective layer increases the structural stability and seismic performance of the building's external insulation system, solves the risk of cracking or falling off of existing external wall insulation systems, and truly integrates the fireproof protective layer, insulation layer, and main building structure into a structural insulation system. Furthermore, it has the same lifespan as the building, improving the overall seismic performance of the building.

[0138] Reduce the impact of thermal break on energy saving: The number of connecting rods 52 between the vertical column 51 on the outside of the built-in prefabricated insulation board 1 and the concrete main structure layer 3 is reduced compared with traditional technology, and thermal break treatment is performed by the first thermal break connecting sleeve 53, which greatly reduces the thermal bridge of the building exterior wall system and improves the building's energy saving effect.

[0139] By using a concrete fireproof shear protection layer that functions as a shear wall, the building's energy efficiency is improved by eliminating the need for floor slab overhangs and achieving complete thermal break treatment at the outer ends of the floor slabs.

[0140] like Figure 2 , 10 As shown in Figures 1 and 12, the curtain wall system 6 includes an interior curtain wall system;

[0141] The inner curtain wall system consists of a curtain wall structure that connects the prefabricated insulation board 1 and the concrete building main structure layer 3 from bottom to top; the upper layer curtain wall structure and the lower layer curtain wall structure are connected by a second connecting block 8.

[0142] The curtain wall structure includes a window sill support rod 61 that runs vertically through the precast insulation board 1, an inner thread 62 that is fixedly connected to the window sill support rod 61 at one end, and a second thermal break connecting sleeve 63 that is connected to the other end of the inner thread 62; the second thermal break connecting sleeve 63 is disposed in the concrete building main structure layer 3; the second thermal break connecting sleeve 63 is connected to the steel reinforcement skeleton 31.

[0143] A horizontal window sill bar 64 is vertically arranged between the two window sill support rods 61; the two window sill support rods 61 and the two window sill bar 64 form a rectangular inner cavity; the window sill bar 64 is set inside the prefabricated insulation board 1. The lower end of the bottom window sill support rod 61 is connected to a bottom window sill pad 81;

[0144] The top end of the top-level window sill support rod 61 is connected to the top-level window sill pad 82; both the bottom-level window sill pad 81 and the top-level window sill pad 82 are fixedly connected to thermal break gaskets 911.

[0145] The window sill is installed using curtain wall technology. A vertical window sill support rod 61 embedded in the prefabricated insulation board 1 and one or more internal threads 62 are installed and fixed to a second thermal break connecting sleeve 63 (organic material thermal break component). The material of the window sill support rod 61 is (can use ≥50mm×3.5mm round tube, ≥50mm×100mm×3.5mm square tube; can use H-shaped steel, etc.), and the material of the internal thread 62 is (≥25mm×2.5mm round tube, ≥25×25×2.5mm square tube, round steel or threaded steel with a diameter ≥12mm, etc.).

[0146] Shear resistance: Adopting the principle of curtain wall structure, structural steel columns and window sill supports 61 are embedded in the prefabricated insulation panel 1. The structural columns are connected to the steel reinforcement skeleton 31 in the main concrete building structure layer, using thermally broken connectors (i.e., inclined inner wires 62 and second thermally broken connecting sleeves 63). Two or more inclined inner wires 62 are set at different angles to the window sill supports 61, forming a triangular structure with the steel reinforcement skeleton 31, which plays a supporting role and increases the stress strength. There can be more than one inner wire 62.

[0147] If the window sill support 61 is a hollow column, the hollow column is filled with concrete; window sill crossbars 64 are added above and below the window and connected to structural columns such as steel sections to form a steel frame at the window, and the window sill 13 is fixed on the steel frame.

[0148] To ensure the window is stable both vertically and vertically, diagonal bracing rods 65 can be added to both the upper and lower parts of the window sill support rod 61 and the window sill crossbar 64.

[0149] The adoption of curtain wall structural principles improves the vertical load-bearing capacity and shear resistance of the external insulation system, thereby enhancing its seismic resistance.

[0150] Reduce the impact of cold bridge on energy saving: Since both the window sill support rod 61 and the window sill crossbar 64 are set inside the prefabricated insulation board 1, a thermal break is formed between the window sill 13 and the building exterior wall, which increases the energy saving effect at the window of the building exterior wall; the inner window sill 15 uses wood or inorganic board with thermal break treatment at the connection with the window, and the outer window sill 14, in addition to considering thermal break treatment, also needs to be designed for drainage.

[0151] The first thermal break connecting sleeve 53 is a cylinder; the first thermal break connecting sleeve 53 is provided with an inner hole, which is threadedly connected to the connecting rod 52; a frustum 531 is provided on the outer circumference of the first thermal break connecting sleeve 53; the frustum 531 is connected to the steel reinforcement skeleton 31; the outer circumference of the first thermal break connecting sleeve 53 is also evenly distributed with right-angled triangular protrusions 532; one right-angled side of the right-angled triangular protrusion 532 is arranged along the axis of the thermal break connecting sleeve 53, and the other right-angled side of the right-angled triangular protrusion 532 is close to the side of the prefabricated insulation layer 1; the second thermal break connecting sleeve 63 has the same structure as the first thermal break connecting sleeve 53.

[0152] In a reinforced concrete core-steel frame structure, the concrete core primarily resists horizontal lateral forces. Due to the material properties, the cross-sections of the two components differ significantly. The lateral stiffness of the reinforced concrete core is much greater than that of the steel frame. As the number of floors increases, the proportion of horizontal loads acting on the building by the core increases. The steel frame mainly bears vertical loads and a small portion of horizontal loads; as the number of floors increases, the proportion of horizontal loads acting on the building by the steel frame decreases. This structure is highly advantageous for structural stress distribution and possesses excellent seismic resistance.

[0153] A construction method for a core tube type thermally broken composite wall system for low-energy buildings.

[0154] Step 1: When making the foundation, the bottom support block 91 and the top support block 92 are pre-embedded in the foundation, and the distance between two adjacent bottom support blocks 91 and two adjacent top support blocks 92 is equal.

[0155] The spacing between the bottom pads 91 of two adjacent pillars is equal to the spacing between two adjacent vertical pillars 51;

[0156] Step 2: Embed the bottom sill pad 81 and the top sill pad 82 in the foundation, with the spacing between two adjacent bottom sill pads 81 and two adjacent top sill pads 82 being equal.

[0157] The spacing between two adjacent bottom pads 81 of the window sill is equal to the spacing between two adjacent window sill support rods 61;

[0158] Step 3: Tie the steel reinforcement cage 31;

[0159] Step 4: Connect and fix the metal mesh 54, support 55, and prefabricated insulation board 1 from the inside to the outside using connecting rods 52 to form the prefabricated insulation assembly.

[0160] Step 5: Fix the bottom vertical support 51 to the bottom support pad 91;

[0161] Step Six: After the steel reinforcement frame 31 is tied, fix the prefabricated insulation assembly assembled in Step Four to the bottom vertical support 51;

[0162] Step 7: Fix the bottom window sill support rod 61 to the bottom window sill pad 81;

[0163] Step 8: Connect the metal mesh 54, support body 55, and prefabricated insulation board 1 from the outside to the inside using connecting rod 52; connect the inclined inner wire 62 and the second thermal break connecting sleeve 63 from the outside to the inside to form a prefabricated insulation body for the windowsill;

[0164] Step 9: Fix the prefabricated insulation body of the windowsill to the bottom windowsill support rod 61;

[0165] Step 10: Similarly, the vertical support columns 51 of the upper and lower floors are connected and locked through the first connecting block 7, and the window sill support rods 61 of the upper and lower floors are connected and locked through the second connecting block 8;

[0166] Step 11: After completing the formwork support on the outside of the fireproof shear protection layer 2 and the main concrete structure layer 3, pour the concrete.

[0167] Step 12: After the roof insulation is completed, extend the vertical column 51 above the roof insulation layer and pour the parapet wall 11;

[0168] Step Thirteen: Inner window sill; inner window sill 15 and outer window sill 14 are treated with thermal break.

[0169] Step Fourteen: Install the windows.

[0170] Example 2

[0171] like Figure 13 As shown in Part A, multiple fixing pins 69 are used to connect the connecting crossbar 52 to the window sill support 61, thus connecting the entire portal system to the curtain wall system. This increases the overall shear strength of the building. Since the multiple fixing pins 69 are located inside the insulation material, thermal bridging will not occur due to the connection, eliminating the need for thermal break treatment. While achieving the requirements of low energy consumption and insulation, it also increases shear strength compared to Example 1. The specifications and materials of the fixing pins 69 can be referenced from the connecting crossbar 52.

[0172] Example 3

[0173] like Figure 13 Part B Figure 14 As shown, the curtain wall system 6 includes an external curtain wall system and an internal curtain wall system;

[0174] The inner curtain wall system consists of a curtain wall structure connecting the precast insulation board 1 and the concrete main building structure layer 3 from bottom to top; the upper layer curtain wall structure and the lower layer curtain wall structure are connected by a second connecting block 8; the outer curtain wall system includes a reinforcing connector connecting the concrete fireproof shear protection layer 2 and the precast insulation board 1; one end of the reinforcing connector is connected to the window sill support rod 61, and the other end is connected to the vertical support column 51; the reinforcing connector is a reinforcing straight rod 66, which is reinforced by... The straight rod 66 connects the precast insulation board 1 to the outer concrete shear fireproof protective layer 2, reinforcing the fixation of the outer protective layer 2 and ensuring the anti-detachment performance of the outer concrete shear protective layer 2 to a greater extent. Since the window sill support rod 61 located in the precast insulation board 1 is connected to the main concrete building structure layer 3 through the connecting internal thread 62 and the second thermal break connecting sleeve 63 of organic material, and has been treated with thermal break, this structure can also avoid cold bridge. The reinforcing straight rod 66 can be precast in the precast insulation board 1 in the factory.

[0175] Example 4

[0176] like Figure 13 , 15 As shown, the reinforcing connector can also be configured as a reinforcing fork 67 with the same form as the internal thread. The reinforcing fork 67 can be two or more forks evenly distributed in any direction in space. The reinforcing fork 67 can be prefabricated in the precast insulation board 1 in the factory. This allows the structure between the precast insulation board 1 and the concrete fireproof shear protection layer 2 to form a stable triangular structure, which is beneficial for both the lateral horizontal force on the outer vertical support 51 and the window sill support 61, and also for the inclined force. This ensures the stability of the entire building.

[0177] Example 5

[0178] like Figure 13 , 16 As shown, this embodiment combines Embodiment 3 and Embodiment 4, using a structure that combines a reinforcing straight rod 66 and a reinforcing fork rod 67 between the vertical upright 51 and the window sill support 61. The choice is made on-site according to actual production needs. Due to the increase in reinforcing parts, the corresponding manufacturing cost will also increase. The construction worker can choose a suitable structure according to the construction requirements and design data.

[0179] Example 6

[0180] like Figure 19 , 20 As shown, in the first structure, the vertical column 51 and the window sill support rod 61 can be connected by a thermal break to achieve a double thermal break. When the insulation board 1 is prefabricated, the pad 56 is prefabricated on the insulation board. The reinforcing rod 66 is divided into two equal sections. The first section of the reinforcing rod 66 is connected to the pad 56 on site or at the factory by bolts. The second section of the reinforcing rod 66 is connected to the first section of the reinforcing rod 66 by a connecting screw 661. A thermal break organic material is provided between the two ends of the reinforcing rod 66. The other end of the second section of the reinforcing rod 66 is fastened to the window sill support rod 61 by bolts.

[0181] The second structure, the reinforcing straight rod 66 can also be made of a continuous thermally broken organic material, and is connected to the vertical column 51 and the window sill support rod 61 by bolts.

[0182] Example 7

[0183] The connecting rod 52 can be inverted V-shaped. One end of the connecting rod 52 is fixedly connected to the vertical column 51, and the other end of the connecting rod 52 is fixedly connected to the first broken bridge connecting sleeve 53.

[0184] Example 8

[0185] like Figure 11As shown, the top floor slab 4 of the top floor is connected to the top floor insulation board 12; the top floor insulation board 12 is connected to the roof concrete protective layer 16; the top surface of the concrete fireproof shear protection layer 2 is flush with the top surface of the roof concrete protective layer 16; a parapet wall 11 is provided on the top of the concrete fireproof shear protection layer 2; the vertical support 51 of the top floor penetrates the parapet wall 11; the precast insulation board 1 and the concrete building main structure layer 3 are connected to the outside of the top floor slab 4 from the outside to the inside; the upper surface of the precast insulation board 1 and the concrete building main structure layer 3 is connected to the lower surface of the top floor insulation board 12.

[0186] The vertical support column 51 installed within the concrete fireproof shear protection layer 2 can also be used as the vertical reinforcement of the parapet wall 11 after the main structure of the building is capped. The parapet wall 11 is connected to the roof concrete protection layer 16 and the concrete fireproof shear protection layer 2. The top insulation board 12 and the precast insulation board 1 surround the main concrete structure layer, which structurally solves the problems of the traditional technology of parapet wall 11 being too complicated and costly in terms of insulation and thermal bridging. The bridging is completely broken at the base of the parapet wall 11.

[0187] Example 9

[0188] like Figure 17 As shown, the exterior wall air conditioning panel 17 can be anchored to the concrete fireproof shear protective layer 2. Triangular supports are installed above and below the fixing surface between the air conditioning panel 17 and the concrete fireproof shear protective layer 2. Since the air conditioning panel 17 does not need to be anchored to the shear wall of the main building, the thermal bridging at the connection node between the air conditioning panel and the main structure in the prior art is solved, achieving a complete bridging solution.

[0189] Example 10

[0190] like Figure 18 As shown, the downpipe 18 on the exterior wall can be anchored to the concrete fireproof shear layer 2, eliminating the need for anchoring to the main shear wall of the building. This solves the thermal bridging problem at the connection point between the air conditioning panel and the main structure in existing technologies, achieving a complete bridging solution.

[0191] Therefore, the main building structure (i.e., the concrete main structural layer 3) using a concrete shear wall structure forms a core tube type of earthquake-resistant structure. The vertical columns 51 set inside the concrete fireproof shear protection layer 2, together with the metal mesh 54 and the curtain wall system 6 with fixed windows, form the outer steel structure; thus forming a core tube type building for high-rise buildings. The invention effect of the core tube type external wall thermal break insulation system is achieved by combining the portal frame insulation system and the curtain wall insulation system.

[0192] Furthermore, thermal break and insulation treatments were implemented on every part of the building, including the exterior walls, floors, windows, parapet walls, air conditioning panels, downpipe joints, the profiles embedded in the insulation material and the foundation anchorage, and the top of the roof, greatly improving the building's energy efficiency.

[0193] This invention, through its simple and easy-to-operate structure and practical applications in various locations, not only ensures the overall safety performance (it will never detach) and seismic performance of the building's external wall insulation system, but also improves the overall building's seismic and other safety performance, completely resolving the safety hazards associated with existing low-energy building technologies in high-rise buildings. Furthermore, it easily meets the national requirements for low-energy buildings, achieving energy savings of 90% or more at a very low cost.

[0194] Embodiments of the present invention have been shown and described. It will be understood by those skilled in the art that various modifications, variations, substitutions and alterations can be made to these embodiments without departing from the principles of the invention, the scope of which is defined by the appended claims and their equivalents.
