Description

Technical Field

[0001] This invention relates to a passive ultra-low energy building, specifically an embedded frame structure for a passive ultra-low energy building and its construction method. Background Technology

[0002] In passive ultra-low energy buildings, steel wire mesh perlite composite insulation board (Type A) serves as the outer formwork for the main structure, combined with concrete pouring to form an external wall and insulation system. This system belongs to the external envelope system of ultra-low energy buildings. All door and window openings (secondary structure) are enclosed by steel wire mesh perlite composite insulation board (Type B, whole board). The inner steel wire mesh is fixed to the main structure walls, floors, and ceilings using rebar segments. The outer steel wire mesh of the Type B board is fixed to the outer steel wire mesh of the Type A board. The joints are reinforced with reinforcing mesh and plaster to form a unified structure. Beams, columns, and shear walls are constructed using Type A boards simultaneously with the main structure. After the main structure is completed, the secondary structure is constructed using Type B boards.

[0003] The steel wire mesh perlite composite insulation board (Type B) has a large overall size, approximately one story high and one span wide. Installation requires a complete hoisting process. Due to its large size and weight, the signalman's line of sight is limited, and coordination between manual labor and the tower crane is difficult, making it hard to guarantee installation accuracy. Furthermore, the application of vapor barriers and breathable membranes requires a smooth, dust-free, and stain-free substrate surface. However, since windows are directly connected to Type B boards, the vapor barriers and breathable membranes are directly adhered to the boards, compromising the airtightness requirements of the building surrounding the window. The standard requires that structural reinforcement measures be taken at the openings of doors and windows in the external insulation system to ensure a safe and reliable connection between the doors / windows and the wall. Moreover, passive windows are heavy (the minimum weight of a single passive window is 110kg), and the direct connection between the window and the B-type panel can lead to a loss of overall stability. Furthermore, the weight of the window relies entirely on the support of the B-type panel, which has insufficient support capacity. The relatively soft insulation material in the B-type panel is prone to deformation and detachment under long-term repeated action of B-type panel load, self-weight load, wind load, and outdoor climate, posing serious safety hazards during later use. Summary of the Invention

[0004] The purpose of this invention is to provide an embedded frame structure for passive ultra-low energy buildings and its construction method, so as to solve the problems of difficult installation and insufficient support of steel wire mesh perlite composite insulation board B-type panels at the openings of existing passive ultra-low energy buildings.

[0005] The present invention is implemented as follows: a passive ultra-low energy building embedded frame structure, including a left insulation board, a right insulation board, an upper insulation board and a lower insulation board, wherein the left insulation board, the right insulation board, the upper insulation board and the lower insulation board are spliced ​​into a rectangular frame structure, a vertical casting groove is provided on the front part of the right side of the left insulation board and the front part of the left side of the right insulation board, and a horizontal casting groove is provided on the front part of the lower side of the upper insulation board and the front part of the upper side of the lower insulation board. The vertical casting groove and the horizontal casting groove are interconnected to form a frame groove, and a concrete frame is cast in the frame groove.

[0006] The left insulation board, right insulation board, upper insulation board, and lower insulation board all include an insulation layer and a concrete protective layer located on both sides of the insulation layer.

[0007] A pre-reserved groove for installing a window frame is provided in the inner circle of the concrete frame.

[0011] The telescopic frame includes a horizontal telescopic rod and a vertical telescopic rod, with the ends of the horizontal and vertical telescopic rods fixedly connected. Both the horizontal and vertical telescopic rods include an inner rod and an outer tube. A through hole is opened on one side of the outer tube. A rack is provided on the inner rod, and a drive wheel is provided at the through hole position of the outer tube.

[0012] The adjustment mechanism includes a fixed sleeve fixed on the support bracket, an inner sleeve sleeved inside the fixed sleeve, a movable support claw fixedly connected to the inner sleeve, and an adjustment rod inserted from the end of the fixed sleeve, the adjustment rod being threadedly connected to the inner sleeve.

[0013] The present invention also discloses a passive ultra-low energy building embedded frame construction method, which includes the following steps.

[0014] a. Fabricate a left insulation board, a right insulation board, an upper insulation board, and a lower insulation board. The left insulation board, the right insulation board, the upper insulation board, and the lower insulation board are spliced ​​together to form a rectangular frame structure. Vertical pouring grooves are opened at the front right side of the left insulation board and the front left side of the right insulation board. Horizontal pouring grooves are opened at the front lower side of the upper insulation board and the front upper side of the lower insulation board. The left insulation board, the right insulation board, the upper insulation board, and the lower insulation board are transported to the construction site.

[0015] b. Install the lower insulation board at the bottom of the opening and connect and fix the lower insulation board to the A-type board.

[0016] c. Install the construction device as described above at the opening. The formwork support mechanism at the bottom of the construction device is supported on the lower insulation board. Install the left and right insulation boards on both sides of the opening respectively. Adjust the left and right width of the telescopic frame to position the left and right insulation boards in the installation position and form effective support. Then connect and fix the left and right insulation boards to the A-type board.

[0017] d. Place the upper insulation block inside the formwork support mechanism on the upper part of the construction device. After adjusting the height of the telescopic frame to lift the upper insulation block to the installation position, connect and fix the upper insulation board to the A-type board.

[0018] e. Shrinkable and expandable frames, precast structural column reinforcement, lintel reinforcement, and window sill beam reinforcement.

[0019] f. Set the window sill beam reinforcement in the horizontal pouring groove of the lower insulation board, and support the formwork support mechanism at the bottom of the construction device on the lower insulation board.

[0020] g. Place the structural column reinforcement bars in the vertical pouring grooves of the left and right insulation boards respectively, and adjust the left and right widths of the expansion joint to position the two structural column reinforcement bars.

[0021] h. Place the lintel reinforcement bars inside the formwork support mechanism on the upper part of the construction device, adjust the height of the telescopic frame to lift the lintel reinforcement bars into the horizontal pouring groove of the upper insulation block and position them.

[0022] i. Connect the reinforcing bars of the structural columns, lintels, and window sills to each other.

[0023] j. Erect structural column formwork, lintel formwork, and window sill beam formwork in the horizontal and vertical pouring trenches, and pour concrete in the horizontal and vertical pouring trenches to form a concrete frame.

[0024] In step j, first adjust the movable support claw to move it away from the fixed support claw, then set the template between the movable support claw and the fixed support claw, and finally adjust the movable support claw closer to the fixed support claw to position the template.

[0025] This invention relates to a passive ultra-low energy building embedded frame structure. The B-type panel is modularly segmented and improved, eliminating the need for tower cranes during installation; installation can be completed manually, significantly reducing construction time and safety hazards. Furthermore, the small modular panels allow for adjustments to the flatness, verticality, and window opening dimensions of the exterior walls, improving installation accuracy. Construction grooves for structural columns, lintels, and window sills are designed within the segmented B-type panels, and prefabrication in a factory ensures high component precision. The cast H-shaped concrete frame enhances the stability and support capacity of the B-type panel. The inner edge of the B-type panel extends beyond the inner edges of the structural columns, lintels, and window sills, allowing the window frame to be embedded within the B-type panel, increasing heat transfer paths and ensuring the thermal performance requirements of the building surrounding the window. Direct connection between the window and the structural columns, lintels, and window sills allows for direct adhesion of waterproof and breathable membranes to the plastered and smoothed concrete structure (structural columns, lintels, and window sills), ensuring the airtightness of the building surrounding the window.

[0026] The passive ultra-low energy building embedded frame structure of the present invention solves the problems of poor air tightness of the building around the window, inability to guarantee the stability of the B-type plate, and easy deformation under the window. It makes the B-type plate, structural column, lintel, window sill beam and main structure form a stable whole, effectively ensuring safe use in the later stage.

[0027] The construction device of the present invention for embedded frame structure of passive ultra-low energy building is simple to operate and easy to install and dismantle. When used for the construction of embedded frame structure of passive ultra-low energy building, it can greatly save labor consumption, reduce subsequent repair procedures, and ensure high overall quality and accurate control of opening size after B-plate installation.

[0028] This invention relates to a passive ultra-low energy building embedded frame construction method. Reinforcing bars are tied, formwork is erected, and concrete is poured at the construction grooves of the structural columns, lintels, and window sills of the B-type slab, forming a stable whole with the B-type slab, structural columns, lintels, window sills, and main structure. Waterproof and breathable membranes are directly adhered to the plastered and smoothed concrete structure (structural columns, lintels, and window sills), ensuring the airtightness requirements of the building around the windows. No drilling is required in the B-type slab, structural columns, lintels, or window sills during construction, ensuring the building's thermal performance and airtightness requirements. It also reduces the need to repair holes in the B-type slab, structural columns, lintels, and window sills after the tie bolts are removed, resulting in high construction efficiency and high-quality concrete structure. Furthermore, it avoids the problem of displacement of the B-type slab during tie bolt reinforcement; the connection between the A and B-type slabs will not crack due to B-type slab displacement, reducing repair procedures and improving construction efficiency and quality.

[0053] The invention will now be further described with reference to the accompanying drawings.

[0054] like Figure 1 , Figure 2 As shown, the passive ultra-low energy building embedded frame structure of the present invention modularly divides the original wire mesh perlite composite insulation board B-type board (hereinafter referred to as B-type board) at the door and window openings into a left insulation board 1, a right insulation board 2, an upper insulation board 3, and a lower insulation board 4. The left insulation board 1, the right insulation board 2, the upper insulation board 3, and the lower insulation board 4 are spliced ​​to form a rectangular frame structure. A vertical pouring groove 5 is provided on the front right side of the left insulation board 1 and the front left side of the right insulation board 2. A horizontal pouring groove 6 is provided on the front lower side of the upper insulation board 3 and the front upper side of the lower insulation board 4. The vertical pouring groove 5 and the horizontal pouring groove 6 are interconnected to form a frame groove. A concrete frame 7 is poured in the frame groove.

[0055] The left and right insulation blocks are located on either side, while the upper insulation board 3 and lower insulation board 4 are located between them. The upper ends of the left and right insulation blocks are flush with the upper end of the upper insulation board 3, and the lower ends of the left and right insulation blocks are flush with the lower end of the lower insulation block, thus forming a U-shaped structure. The vertical pouring grooves 5 on the left and right insulation blocks form structural columns after pouring, the horizontal pouring groove 6 on the upper insulation block forms lintels after pouring, and the horizontal pouring groove 6 on the lower insulation board 4 forms window sill beams after pouring.

[0056] By dividing the original B-type panels at the opening into four parts, the entire structure can be installed manually without the need for hoisting equipment such as tower cranes, significantly reducing construction time and safety hazards. The small-scale modular panel construction allows for adjustments to the flatness, verticality, and window opening dimensions of the exterior wall, improving installation accuracy. Casting grooves for structural columns, lintels, and window sills are designed within the divided B-type panels and prefabricated in a factory, resulting in high component precision. Since the casting grooves are not cut on-site, dust and noise pollution at the construction site are reduced.

[0057] The vertical pouring groove 5 extends through the left insulation board 1 and the right insulation board 2 in the vertical direction, while the horizontal pouring groove 6 extends through the upper insulation board 3 and the lower insulation board 4 in the width direction. Therefore, the horizontal pouring groove 6 and the vertical pouring groove 5 are interconnected to form a U-shaped retaining frame groove. Simultaneously, the two sides of the retaining frame groove extend vertically and vertically to the foundation structure of the opening. After the concrete retaining frame 7 is poured within the retaining frame groove, the concrete retaining frame 7 connects to the foundation structure above and below the opening, transferring the force from the upper structure to the concrete retaining frame 7. At the same time, the weight of the B-type slab can also be transferred downwards through the concrete retaining frame 7. The concrete retaining frame 7 strengthens the structural strength of the B-type slab and improves its support capacity.

[0058] Since the left insulation board 1, right insulation board 2, upper insulation board 3 and lower insulation board 4 are obtained by dividing the B-type board, the basic structure of the left insulation board 1, right insulation board 2, upper insulation board 3 and lower insulation board 4 is the same as that of the B-type board, all of which include an insulation layer and a concrete protective layer located on the front and back sides of the insulation layer.

[0059] The concrete frame 7 poured into the frame groove does not completely fill the entire frame groove. Instead, a reserved groove 9 for installing the window frame is left in the inner circle of the concrete frame 7. The reserved groove 9 is 30-50mm wide. In this way, when installing the window frame, the window frame can be embedded in the B-type plate, thereby increasing the heat transfer path and ensuring the thermal performance requirements of the building around the window.

[0060] A raised overlapping edge 12 is provided on the right side of the left insulation board 1 and the left side of the right insulation board 2. The lower end of the overlapping edge 12 contacts the upper side of the lower insulation board 4, and the upper end of the overlapping edge 12 contacts the lower side of the upper insulation board 3. After the left insulation board 1, right insulation board 2, upper insulation board 3 and lower insulation board 4 are spliced ​​together, the overlapping edge 12 forms a temporary support for the left insulation board 1, right insulation board 2, upper insulation board 3 and lower insulation board 4.

[0061] Tongue and groove joints 8 are provided around the rear sides of the left insulation board 1, right insulation board 2, upper insulation board 3 and lower insulation board 4. The tongue and groove joints 8 are used for connecting them to each other or connecting the B-type board and the A-type board 11.

[0062] A thermal insulation block 10 is provided in the inner ring of the B-type panel. The thermal insulation block 10 serves as the base for bonding the vapor-permeable membrane, and plays the role of thermal insulation and heat insulation, while ensuring the airtightness around the window.

[0063] The structure of the left insulation board 1 is as follows: Figures 5-9 As shown; the structure of the right insulation board 2 is symmetrical to that of the left insulation board 1; the structure of the upper insulation board 3 is as follows. Figures 10-12 As shown; the structure of the lower insulation board 4 is as follows Figures 13-15 As shown.

[0064] Before splicing the left insulation board 1, right insulation board 2, upper insulation board 3, and lower insulation board 4, as shown... Figure 3 As shown, after splicing the B-type plates inside the opening, it forms... Figure 4 The structure shown, after the concrete frame 7 is poured, results in the following: Figure 1 The structure shown.

[0065] The opening can be a single-span structure, such as... Figure 4 As shown, a set of left insulation board 1, right insulation board 2, upper insulation board 3, and lower insulation board 4 are installed inside the opening; the opening can also be a multi-span structure, such as... Figure 1 As shown, multiple sets of left insulation board 1, right insulation board 2, upper insulation board 3 and lower insulation board 4 are installed side by side inside the opening.

[0066] Using the passive ultra-low energy building embedded frame structure of the present invention, the window is directly connected to the structural column, lintel, and window sill beam, which allows the waterproof vapor barrier membrane and waterproof breathable membrane to be directly pasted onto the concrete structure (structural column, lintel, and window sill beam) after plastering and polishing, ensuring the airtightness requirements of the building around the window.

[0067] like Figure 16As shown, the present invention also discloses a construction device 13 for the embedded frame structure of passive ultra-low energy consumption buildings. The B-type panel of the present invention no longer uses hoisting equipment for overall hoisting and installation, but is manually spliced ​​and installed by left insulation board 1, right insulation board 2, upper insulation board 3 and lower insulation board 4. In order to improve the construction efficiency of manual installation, the left insulation board 1, right insulation board 2, upper insulation board 3 and lower insulation board 4 are proposed.

[0068] The construction device 13 includes a rectangular telescopic frame 13-1, and template 15 support mechanisms 13-2 are respectively provided on the four sides of the telescopic frame 13-1. The template 15 support mechanism 13-2 includes a support bracket 13-8, a fixed support claw 13-9 is provided on the rear side of the support bracket 13-8, and a movable support claw 13-10 is provided on the front side of the support bracket 13-8. The movable support claw 13-10 is connected to the support bracket 13-8 through an adjustment mechanism.

[0069] Two horizontal telescopic rods and two vertical telescopic rods form a rectangular telescopic frame 13-1. The width and height of the telescopic frame 13-1 can be adjusted by the horizontal and vertical telescopic rods. Both the horizontal and vertical telescopic rods include an inner rod 13-3 and an outer sleeve 13-4. Figure 17 As shown, a through hole 13-6 is opened on one side of the outer tube 13-4, and a rack 13-5 is provided on the inner rod 13-3. A drive wheel 13-7 is provided at the through hole 13-6 of the outer tube 13-4. The drive wheel 13-7 and the rack 13-5 mesh with each other. Rotating the drive wheel 13-7 will drive the inner rod 13-3 to move inside the outer tube 13-4. A crank is connected to the shaft of the drive wheel 13-7, and the operator can easily adjust the length of the telescopic rod by cranking the crank.

[0070] A bubble level 16 and a scale 17 are provided on the outer tube 13-4. The bubble level 16 is used to detect the levelness of the telescopic rod, and the scale 17 is used to control the spacing between the left and right formwork 15 support mechanisms 13-2 or the upper and lower formwork 15 support mechanisms 13-2, thereby controlling the construction accuracy.

[0071] The template 15 support mechanism 13-2 is located on the four sides of the telescopic frame 13-1, and at least two template 15 support mechanisms 13-2 are provided on each side. The template 15 support mechanism 13-2 extends outward from the telescopic frame 13-1 to support the B-shaped plate, the frame reinforcement and the template 15 and other structures around it.

[0072] like Figure 18As shown, the support bracket 13-8 is a plate-shaped structure. The fixed support claw 13-9 and the movable support claw 13-10 are located on its front and rear sides, respectively. During the installation of the B-type plate, the left insulation plate 1, the right insulation plate 2, the upper insulation plate 3 or the lower insulation plate 4 are located between the fixed support claw 13-9 and the movable support claw 13-10, and the support bracket 13-8 supports the B-type plate.

[0073] like Figure 19 As shown, the fixed support claw 13-9 and the movable support claw 13-10 have their distance adjusted by an adjustment mechanism. The adjustment mechanism includes a fixed sleeve 13-11 fixed on the back of the support bracket 13-8, an inner sleeve 13-12 sleeved inside the fixed sleeve 13-11, and the movable support claw 13-10 fixedly connected to the inner sleeve 13-12. An adjustment rod 13-13 is inserted through the end of the fixed sleeve 13-11 and is threadedly connected to the inner sleeve 13-12. Rotating the adjustment rod 13-13 can move the movable support claw 13-10 away from or closer to the support bracket 13-10.

[0074] The construction device 13 of the present invention for embedded frame structures in passive ultra-low energy buildings is used for the installation of B-type panels, positioning of frame reinforcement, and fixing of the casting formwork 15 during frame structure construction. The construction device 13 of the present invention is simple to operate and easy to install and dismantle. When used for embedded frame structures in passive ultra-low energy buildings, it can greatly save labor costs, reduce subsequent repair procedures, and ensure high overall quality and accurate control of opening dimensions after B-type panel installation.

[0075] The passive ultra-low energy building embedded frame structure of the present invention solves the problems of poor air tightness of the building around the window, inability to guarantee the stability of the B-type plate, and easy deformation under the window. It makes the B-type plate, structural column, lintel, window sill beam and main structure form a stable whole, effectively ensuring safe use in the later stage.

[0076] The present invention also discloses a passive ultra-low energy building embedded frame construction method, which includes the following steps.

[0077] a. Fabricate left insulation board 1, right insulation board 2, upper insulation board 3, and lower insulation board 4. The left insulation board 1, right insulation board 2, upper insulation board 3, and lower insulation board 4 are spliced ​​together to form a rectangular frame structure. Vertical pouring grooves 5 are opened on the front right side of the left insulation board 1 and the front left side of the right insulation board 2. Horizontal pouring grooves 6 are opened on the front lower side of the upper insulation board 3 and the front upper side of the lower insulation board 4. The left insulation board 1, right insulation board 2, upper insulation board 3, and lower insulation board 4 are transported to the construction site.

[0078] Before processing and manufacturing, determine the dimensions of the B-type panel at the opening, as well as the position and dimensions of the horizontal pouring groove 6, the vertical pouring groove 5, and the tongue and groove joint 8. Produce a detailed sectioning diagram of the B-type panel, dividing it into a left insulation panel 1, a right insulation panel 2, an upper insulation panel 3, and a lower insulation panel 4. During the production of the B-type panel, prefabricate the pouring grooves and tongue and groove joint 8.

[0080] b. Positioning and layout: First, install the lower insulation board 4 at the bottom of the opening. After adjusting the position and elevation of the lower insulation board 4, connect and fix the lower insulation board 4 to the steel wire mesh perlite composite insulation board A-type board 11 (hereinafter referred to as A-type board 11) on the outside of the main structure.

[0081] c. Install the construction device 13 as described above at the opening. The formwork 15 support mechanism 13-2 at the bottom of the construction device 13 is supported on the lower insulation board 4.

After adjusting the left and right widths of the telescopic frame 13-1 to position the left insulation board 1 and the right insulation board 2 in the installation position and form effective support, connect and fix the left insulation board 1 and the right insulation board 2 to the A-type board 11.

[0082] d. Place the upper insulation block inside the template 15 support mechanism 13-2 on the upper part of the construction device 13. After adjusting the height of the telescopic frame 13-1 to lift the upper insulation block to the installation position, connect and fix the upper insulation board 3 to the A-type board 11.

[0083] The installation of the left insulation board 1, right insulation board 2, upper insulation board 3, and lower insulation board 4 is performed using the construction device 13 of the present invention. Figure 20 As shown, the construction device 13 supports and positions the left insulation board 1, right insulation board 2, upper insulation board 3, and lower insulation board 4. After the B-type board is connected and fixed to the A-type board 11, the left insulation board 1, right insulation board 2, upper insulation board 3, and lower insulation board 4 are supported by the A-type board 11.

[0088] i. Connect the reinforcing bars of the structural columns, lintels, and window sills to each other.

[0089] j. such as Figure 21 , 22 As shown in Figure 23, structural column formwork 15, lintel formwork 15 and window sill beam formwork 15 are erected in the horizontal pouring trench 6 and the vertical pouring trench 5. Concrete is poured in the horizontal pouring trench 6 and the vertical pouring trench 5 to form a concrete frame 7. After the concrete has cured to the required strength, the construction device 13 and the formwork 15 are removed.

[0090] First, adjust the movable support claw 13-10 to move it away from the fixed support claw 13-9. Then, set the template 15 between the movable support claw 13-10 and the fixed support claw 13-9. Finally, adjust the movable support claw 13-10 closer to the fixed support claw 13-9 to position the template 15.

[0091] Wooden blocks 14 are also placed in the pouring trench. After the formwork 15 and wooden blocks 14 are removed, a reserved groove 9 for installing the window frame is formed in the pouring trench.

[0092] The passive ultra-low energy building embedded frame construction method of the present invention involves binding steel bars, setting up formwork 15, and pouring concrete at the construction grooves of the structural columns, lintels, and window sills of the B-type slab, so that the B-type slab, structural columns, lintels, window sills, and main structure form a stable whole.

[0093] Waterproof vapor barrier membranes and waterproof breathable membranes are directly pasted onto the concrete structure (structural columns, lintels, window sills) after plastering and polishing to ensure the airtightness requirements of the building around the window.

[0094] During construction, there is no need to drill holes in the B-type slabs, structural columns, lintels, and window sills, which ensures the building's thermal performance and airtightness requirements. It also reduces the need to repair holes in the B-type slabs, structural columns, lintels, and window sills after the tie bolts are removed, resulting in high construction efficiency and high-quality concrete structure forming.

[0095] This also avoids the problem of displacement of the B-type plate when reinforced with tie bolts. The connection between the A and B-type plates will not crack due to displacement of the B-type plate, reducing the repair process and improving construction efficiency and quality.
