Description

Technical Field

[0001] The invention belongs to the technical field of green buildings, and in particular relates to a dry hanging connection structure of a passive ultra-low energy consumption building and an installation method thereof. Background Art

[0002] Passive ultra-low energy buildings are a new type of green building that requires minimizing the thermal bridge effect. Thermal bridges refer to reinforced concrete or metal beams, columns, ribs and other parts in the enclosure structure such as the exterior wall and roof. These parts are called thermal bridges because they have strong heat transfer capabilities, dense heat flow and low inner surface temperature. The thermal bridge effect will cause a building to waste a lot of energy within its life cycle, and will also cause moisture and mold in the thermal bridge parts, and even reduce the living experience of the building.

[0003] Dry-hang connectors are often used in buildings to connect building exterior wall panels, HVAC pipes, etc. The dry-hang connector has a simple structure, but in order to achieve reliable connection, a large number of dry-hang connectors need to be set at multiple locations between the connected components and the building. Dry-hang connectors are usually made of steel, and one end of the connector extends into or connects to the building wall or structure. A large number of dry-hang connectors that extend into or directly connect to the building will produce a large number of thermal bridge effects, increasing the building's energy consumption while reducing the living experience. Therefore, it is necessary to improve the dry-hang connectors. Summary of the invention

[0004] The purpose of the present invention is to provide a dry hanging connection structure of a passive ultra-low energy consumption building and an installation method thereof, which solves the problem that the current dry hanging connection parts will produce a large number of thermal bridge effects.

[0010] In the transverse direction, the cross-shaped torsion-resistant steel bar runs through the series holes and the dry hanging connectors; in the longitudinal direction, the longitudinal connector runs through the cross-shaped torsion-resistant steel bar;

[0011] A first heat-insulating block is arranged in the area where the cross-shaped torsion-resistant steel bar passes through the series hole; in the area where the cross-shaped torsion-resistant steel bar is connected to the longitudinal connector, a second heat-insulating block is arranged in the upper and lower notches of the cross-shaped torsion-resistant steel bar.

[0012] Furthermore, the series connection holes are square, and the cross-shaped torsion-resistant steel bars are arranged in an X shape in the series connection holes.

[0013] Furthermore, the cross-sectional shapes of the first thermal insulation block and the second thermal insulation block are isosceles triangles, and the first thermal insulation block is respectively clamped in the four angle regions of the cross-shaped torsion-resistant steel bar.

[0014] Furthermore, the first heat insulating block and the second heat insulating block are made of plastic or wood.

[0015] Furthermore, the bearing plate adopts I-beam and the cross-shaped torsion-resistant steel bar adopts equal-limb cross-shaped steel.

[0016] Furthermore, when multiple dry hanging connectors are provided between two adjacent dry hanging force-bearing members, a hoop plate is provided between the two adjacent dry hanging connectors, and a plurality of hoop plate holes corresponding to the series holes are opened on the hoop plate, and a cross-shaped torsion-resistant steel bar runs through the hoop plate holes.

[0017] Furthermore, the hoop plate hole is square, and the cross-shaped torsion-resistant steel bar is arranged in the hoop plate hole in an X shape.

[0018] The present invention also discloses a method for installing the dry hanging connection structure of the passive ultra-low energy consumption building, which comprises the following steps:

[0019] S1. Install the dry hanging force-bearing piece at the predetermined position;

[0020] S2, passing the cross-shaped torsion-resistant steel bar through the series holes, and laying the first heat insulation block at the same time when the cross-shaped torsion-resistant steel bar passes through the series holes;

[0021] S3, arranging the second heat insulation block at a predetermined position in the upper and lower notches of the cross-shaped torsion steel bar;

[0022] S4, arranging the dry hanging connector at a predetermined position;

[0023] S5. Pass the longitudinal connector through the force-transmitting connecting plate, the second heat-insulating block and the cross-shaped torsion-resistant steel bar to complete the installation.

[0024] Compared with the prior art, the present invention has the following beneficial technical effects:

[0025] The present invention discloses a dry-hanging connection structure of a passive ultra-low energy consumption building, comprising a plurality of dry-hanging force-bearing members and a plurality of cross-shaped torsion-resistant steel bars; a dry-hanging connection member is arranged between two adjacent dry-hanging force-bearing members; the dry-hanging force-bearing member comprises a first end plate and a force-bearing plate, and a plurality of series holes are opened on the force-bearing plate; the dry-hanging connection member comprises a second end plate and a force-transmitting connection plate, and the force-transmitting connection plate is connected to the cross-shaped torsion-resistant steel bars through a plurality of longitudinal connection members; in the transverse direction, the dry-hanging force-bearing members and the dry-hanging connection member are connected by means of a plurality of cross-shaped torsion-resistant steel bars with strong torsion-resistant ability, and in the area where the cross-shaped torsion-resistant steel bars are connected to the dry-hanging force-bearing members, the cross-shaped torsion-resistant steel bars in the series holes can be reinforced for torsion resistance by means of a first insulation block, and the cross-shaped torsion-resistant steel bars can also be prevented from torsion-resistant. The torsion-resistant steel bars are in contact with the dry-hanging force-bearing pieces to avoid the occurrence of a thermal bridge effect between the cross-shaped torsion-resistant steel bars and the dry-hanging force-bearing pieces; in the longitudinal direction, the longitudinal connectors are reliably connected to the cross-shaped torsion-resistant steel bars, and the cross-shaped torsion-resistant steel bars in the same column are connected in series into a whole, so that the cross-shaped torsion-resistant steel bars in the same column are subjected to force together; in the area where the cross-shaped torsion-resistant steel bars are connected to the longitudinal connectors, a second insulation block is arranged in the upper and lower notches of the cross-shaped torsion-resistant steel bars to avoid the occurrence of a thermal bridge effect between the cross-shaped torsion-resistant steel bars and the dry-hanging connectors, and to facilitate the reliable connection of the longitudinal connectors with the cross-shaped torsion-resistant steel bars. Secondly, it can also prevent the cross-shaped torsion-resistant steel bars and the longitudinal connectors from rusting at the connection between them during long-term use, thereby causing the force transmission connecting plate to become loose. At the same time, due to the reliable connection between the building exterior wall panels or other building components and the dry hanging connectors, the number of dry hanging bearings set at the same height on a certain facade or inside the building is reduced. Under the premise that there is no thermal bridge effect between the cross-shaped torsion steel bars and the dry hanging bearings, only a small number of dry hanging bearings need to be sealed and wrapped around. Based on this design principle, only a small number of sealed and wrapped parts will exist in the later stage of the building, which improves construction efficiency, effectively reduces thermal bridge effects, helps reduce building energy consumption, and is suitable for passive ultra-low energy buildings.

[0026] Furthermore, the series holes have a square cross-section, and the two limbs of the cross-shaped torsion-resistant steel bar should be vertical. In this way, while ensuring that the cross-shaped torsion-resistant steel bar is easy to process, the series holes with square cross-sections can maximize the torsion-resistant limiting effect on the four limbs of the cross-shaped torsion-resistant steel bar.

[0027] Furthermore, at least one hoop plate is arranged between the two dry hanging connectors, and a hoop plate hole is arranged on the hoop plate. The cross-shaped torsion-resistant steel bar is in direct contact with the four sides of the hoop plate hole, which can prevent the single cross-shaped torsion-resistant steel bar from torsion deformation, and connect all the cross-shaped torsion-resistant steel bars between the two dry hanging force-bearing members into a whole, thereby improving the torsion resistance of the cross-shaped torsion-resistant steel bars; the force transmission connecting plate is connected between the cross-shaped torsion-resistant steel bars by means of a longitudinal connecting member, and the longitudinal connecting member itself has a strong ability to resist shear deformation. If the cross-shaped torsion-resistant steel bar has a tendency to deform, due to the presence of the hoop plate, multiple vertical rows of longitudinal connecting members must tend to be parallel and equidistant, and the upper or lower connection points of the force transmission connecting plate and the cross-shaped torsion-resistant steel bar must also be located on the same straight line; the through-type connected longitudinal connecting member connects the cross-shaped torsion-resistant steel bars in the same vertical row into one, and the hoop plate cooperates with the longitudinal connecting member to make all the cross-shaped torsion-resistant steel bars form a whole, forming a tendency of overall torsion deformation. Such a design principle helps to increase the bearing capacity of the super-long dry hanging connector. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The present invention is further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0045] like Figure 1 As shown, the present invention discloses a dry hanging connection structure of a passive ultra-low energy consumption building, including a plurality of dry hanging holding members 1 and a plurality of cross-shaped torsion-resistant steel bars 2; a dry hanging connection member 3 is provided between two adjacent dry hanging holding members 1.

[0046] like Figure 2-6 As shown, the dry hanging force-holding member 1 is connected by a first end plate 11 and a force-holding plate 13. The first end plate 11 is provided with a plurality of first connection holes 12, which facilitate bolt connection of the dry hanging force-holding member 1 with the building in the later stage; the force-holding plate 13 is used to bear the deadweight load of the connecting member of the present application and the load transmitted by the connected object in the later stage. The force-holding plate 13 is made of I-shaped steel for easy processing. The web part of the force-holding plate 13 is provided with a row of series holes 14 in parallel from top to bottom, and the series holes 14 are rectangular. The series holes 14 are used to pass the cross-shaped torsion-resistant steel bars 2.

[0047] The cross-shaped torsion-resistant steel bar 2 is the main force transmission component, and is made of equal-limb cross-shaped steel or equal-limb cross-shaped profile. The cross-shaped torsion-resistant steel bar 2 has a regular cross section and is easy to process and manufacture. The cross-shaped torsion-resistant steel bar 2 has a strong anti-torsion ability. In the later stage, the dry hanging connector 3 can make the dry hanging connector of the present application less deformed or even not deformed. In addition, the cross-shaped torsion-resistant steel bar 2 can also be strictly limited by the serial holes 14 of the dry hanging force-bearing member 1 torsional deformation, further preventing the cross-shaped torsion-resistant steel bar 2 from deformation.

[0048] like Figure 3 and Figure 4 As shown, a first heat-insulating block 51 is provided in the area where the cross-shaped torsion-resistant steel bar 2 passes through the series hole 14. The first heat-insulating block 51 is made of a high-strength plastic product or a wood block that is corrosion-resistant and heat-insulating.

[0049] like Figure 4 As shown, the series hole 14 is a square, the cross-sectional shape of the first heat insulation block 51 is an isosceles triangle, and the four first heat insulation blocks 51 are respectively clamped around the cross-shaped torsion steel bar 2, and the size of the first heat insulation block 51 passing through the series hole 14 area should ensure that the cross-shaped torsion steel bar 2 does not have direct contact with the bearing plate 13, preventing heat from being transferred to the interior of the building along the cross-shaped torsion steel bar 2 and the bearing plate 13 in sequence, which can effectively reduce the thermal bridge effect. In addition, when the cross-shaped torsion steel bar 2 has a tendency to twist and deform in the series hole 14, the first heat insulation block 51 with high compressive strength can reinforce the cross-shaped torsion steel bar 2 in the series hole 14 to prevent the cross-shaped torsion steel bar 2 from twisting.

[0050] The force transmission component is in a cross shape. Firstly, it is considered that the cross-shaped steel is easy to obtain, the cross-shaped steel itself has strong torsion resistance, and the cross shape is easy to be embedded with a regular quadrilateral. After the regular quadrilateral hole is embedded with the cross shape, it can play a limiting and constraining role on each limb of the cross-shaped torsion-resistant steel bar 2 that contacts the regular quadrilateral hole; finally, the gap between the cross-shaped limbs is a triangle, and it is also easy to arrange the first insulation block 51 with a regular shape, so that the dry hanging connector 3 is connected to the cross-shaped torsion-resistant steel bar 2 as a whole.

[0051] The number of dry-hanging connectors 3 provided between two adjacent dry-hanging holders 1 depends on the distance between the two adjacent dry-hanging holders 1, the weight of the connected object and the building facade effect. Designers should reasonably design the size and layout of the dry-hanging holders 1 according to the weight of the connected building components and the building facade effect. When the distance between the dry-hanging holders 1 is far, multiple dry-hanging connectors 3 are provided between the two adjacent dry-hanging holders 1; when the distance between the dry-hanging holders 1 is close, only one dry-hanging connector 3 is provided.

[0052] like Fig.10 and 11 As shown, the dry hanging connector 3 includes a second end plate 31 and two symmetrically arranged force transmission connecting plates 33, the force transmission connecting plates 33 are vertically connected to the second end plate 31, and a plurality of second connecting holes 32 are opened on the second end plate 31 to facilitate the later connection of the building exterior wall panels and other building components. The force transmission connecting plates 33 are arranged above and below the two rows of cross-shaped torsion steel bars 2, and are reliably connected by longitudinal connecting members 34 that penetrate the force transmission connecting plates 33 and the cross-shaped torsion steel bars 2, and the longitudinal connecting members 34 are anchor rods, bolts or screws.

[0053] In the area where the cross-shaped torsion-resistant steel bar 2 is connected to the longitudinal connector 34, the cross-shaped torsion-resistant steel bar 2 is also provided with a second insulation block 52 in the upper and lower grooves. The cross-shaped torsion-resistant steel bar 2 has an X-shaped cross-section, and it is inconvenient for the cross-shaped torsion-resistant steel bar 2 and the force transmission connecting plate 33 to be directly penetrated and connected by the longitudinal connector 34. The second insulation block 52 is provided to firstly facilitate the reliable connection between the longitudinal connector 34 and the cross-shaped torsion-resistant steel bar 2, and secondly to prevent the ultra-long dry hanging connector from rusting at the connection between the cross-shaped torsion-resistant steel bar 2 and the longitudinal connector 34 during long-term use, thereby causing the force transmission connecting plate 33 to become loose.

[0054] Preferably, Figure 1 , 7 As shown in FIG8 , in an extra-long dry hanging connector, when the distance between two adjacent dry hanging holding members 1 is far, at least one hoop plate 4 should be arranged between the two dry hanging connectors 3, and a hoop plate hole 41 is arranged on the hoop plate 4. The four sides of the cross-shaped torsion-resistant steel bar 2 are in direct contact with the hoop plate hole 41. Firstly, it can prevent a single cross-shaped torsion-resistant steel bar 2 from torsional deformation, and more importantly, it can enhance the overall torsional resistance of all the cross-shaped torsion-resistant steel bars 2 between the two dry hanging holding members 1.

[0055] like Figure 8 and 9 As shown, the hoop plate hole 41 is square, and the cross-shaped torsion steel bar 2 is arranged in the hoop plate hole 41 in an X shape.

[0056] The force transmission connecting plate 33 in the dry hanging connecting piece 3 is connected to the upper and lower rows of cross-shaped torsion-resistant steel bars 2 by means of the longitudinal connecting piece 34. The longitudinal connecting piece 34 itself has a strong ability to resist shear deformation. If the cross-shaped torsion-resistant steel bar 2 has a tendency to deform, due to the presence of the hoop plate 4, the multiple vertical rows of longitudinal connecting pieces 34 will inevitably tend to be parallel and equidistant, and the upper or lower connection points of the force transmission connecting plate 33 and the cross-shaped torsion-resistant steel bar 2 will inevitably be on the same straight line.

[0057] The through-type longitudinal connector 34 connects the cross-shaped torsion-resistant steel bars 2 in the same vertical row into one, and the hoop plate 4 cooperates with the longitudinal connector 34 to make all the cross-shaped torsion-resistant steel bars 2 form a whole, forming an overall torsional deformation trend. This design principle helps to increase the bearing capacity of the extra-long dry hanging connector.

[0058] Preferably, the series holes 14 and the hoop plate holes 41 should have square cross-sections, and the two limbs of the cross-shaped torsion-resistant steel bar 2 should be vertical. In this way, while ensuring that the cross-shaped torsion-resistant steel bar 2 is easy to process, the series holes 14 and the hoop plate holes 41 can tightly constrain the cross-shaped torsion-resistant steel bar 2 to prevent the cross-shaped torsion-resistant steel bar 2 from torsional deformation when passing through the area of ​​the series holes 14 and the hoop plate holes 41.

[0059] The reasons are as follows: Assuming that the series holes 14 and the hoop plate holes 41 are made into a rectangle, first of all, if the height is greater than the width, not only will the two limbs of the cross-shaped torsion-resistant steel bar 2 not be perpendicular, which is difficult to manufacture, but it will also weaken the torsion resistance of the cross-shaped torsion-resistant steel bar 2, and the height of the force plate 13 will also be increased accordingly to accommodate the series holes 14 and the hoop plate holes 41, which will eventually make the height of the connector too large. If the width of the series holes 14 and the hoop plate holes 41 is greater than the height, the cross-shaped torsion-resistant steel bar 2 is also difficult to manufacture. Although this design method will improve the torsion resistance of the cross-shaped torsion-resistant steel bar 2, the length of the force plate 13 needs to be increased in order to adapt to the size and load-bearing capacity of the series holes 14 and the hoop plate holes 41, which will increase the building area and cause a waste of building space. Therefore, a square with a cross-shaped torsion-resistant steel bar with two perpendicular limbs is the best.

[0060] The principle of preventing thermal bridges in the dry hanging connection structure of the present invention is: relying on multiple cross-shaped torsion-resistant steel bars 2 with strong torsion resistance to connect the dry hanging connectors 3, in the area where the cross-shaped torsion-resistant steel bars 2 are connected to the dry hanging support members 1, relying on the first insulation block 51, the cross-shaped torsion-resistant steel bars 2 in the series holes 14 can be torsionally reinforced, and the cross-shaped torsion-resistant steel bars 2 can be prevented from contacting the dry hanging support members 1, thereby avoiding the occurrence of a thermal bridge effect between the cross-shaped torsion-resistant steel bars 2 and the dry hanging support members 1.

[0061] At the same time, since the building exterior wall panels or other building components are reliably connected to the dry hanging connector 3, the number of dry hanging force-bearing members 1 set at the same height on a certain facade of the building or inside the building is reduced. Under the premise that there is no thermal bridge effect between the cross-shaped torsion steel strips 2 and the dry hanging force-bearing members 1, only a small number of dry hanging force-bearing members 1 need to be specially insulated and sealed around. Based on this design principle, the work area and workload of special insulation treatment of the facade of the building in the later stage will be greatly reduced, which improves the construction efficiency, can also effectively reduce the thermal bridge effect, help reduce the building energy consumption, and is suitable for passive ultra-low energy consumption buildings.

[0062] The dry hanging connection structure installation method of the present invention comprises the following steps:

[0063] S1, installing the dry hanging holding member 1 at a predetermined position;

[0064] S2, passing the cross-shaped torsion-resistant steel bar 2 through the series hole 14, and simultaneously laying the first heat insulation block 51 when the cross-shaped torsion-resistant steel bar 2 passes through the series hole 14;

[0065] S3, arranging the second heat insulation block 52 at a predetermined position in the upper and lower notches of the cross-shaped torsion steel bar 2;

[0066] S4, arranging the dry hanging connector 3 at a predetermined position;

[0067] S5. Insert the longitudinal connector 34 through the force transmission connecting plate 33, the second heat insulation block 52 and the cross-shaped torsion steel bar 2 to complete the installation.
