Description

Technical Field

[0001] The present invention relates to the field of building structure technology, in particular to a heavy equipment roof node of a passive ultra-low energy consumption building. Background Art

[0002] Passive ultra-low energy buildings are a new type of building that significantly reduces heat loss, ensuring residents feel warm in winter and cool in summer. To achieve this passive insulation, the building's thermal bridge effect must be minimized. Thermal bridges primarily form within the building's exterior walls and roof, where reinforced concrete or metal beams, columns, and ribs form. Because these areas have high heat transfer capabilities, intensive heat flow, and relatively low internal surface temperatures, thermal bridges can significantly degrade the living experience.

[0003] When using heavy equipment in passive ultra-low energy buildings, an appropriate equipment roof foundation needs to be set up. However, the current equipment roof nodes mainly use anti-corrosion wood anchor bolts in combination with conventional insulation methods to achieve insulation effects. In these node methods, there are still a large number of gaps in the connection between the insulation material and the anti-corrosion wood and the foundation, which will lead to the deterioration of the vapor barrier of the equipment roof. In addition, because the anchor bolts are used to penetrate the entire anti-corrosion wood and the equipment foundation, the current equipment roof has a thermal bridge effect. Therefore, it is necessary to propose a new equipment roof node suitable for passive ultra-low energy buildings. Summary of the Invention

[0020] Furthermore, the tensile connector inside the connecting rod further increases the load-bearing capacity of the connecting block.

[0021] Furthermore, the heat-insulating sleeve can avoid direct contact between the connecting rod and the connecting block, thereby more comprehensively isolating the connecting rod and the connecting block, thereby achieving the purpose of eliminating the thermal bridge effect.

DETAILED DESCRIPTION

[0034] The present invention will be further described in detail below with reference to specific embodiments, which are intended to explain the present invention rather than to limit it.

[0035] Example 1

[0036] A heavy equipment roof node of a passive ultra-low energy building, referring to Figure 1 , including an equipment roof foundation, an insulation layer 14 and an embedded plate 9 arranged from bottom to top. The equipment roof foundation includes a structural roof 1 and an equipment foundation 2. The equipment foundation 2 has a rectangular cross-section, and the insulation layer 14 is covered on the outside of the equipment foundation 2.

[0037] Reference Figure 2 The insulation layer 14 includes an upper insulation layer and two side insulation layers 203, refer to Figure 3 The upper insulation layer includes a middle insulation layer 6 and an anti-corrosion insulation layer 8 arranged from bottom to top. In this embodiment, the middle insulation layer 6 is made of high-density graphite polystyrene board material, which has good insulation performance and is easy to process and cut; the anti-corrosion insulation layer 8 is made of anti-corrosion wood.

[0038] Reference Figure 4 、 5 , a plurality of mounting members 3 are provided on the equipment foundation 2, and the mounting members 3 are embedded in the middle insulation layer 6, referring to Figure 6 、 7 The mounting member 3 includes a connecting block 5, a heat-resistant block 13 and a connecting rod 7. The heat-resistant block 13 is made of rubber material. The connecting block 5 is connected to the equipment foundation 2. A plurality of connecting pads 11 are provided on the side of the connecting block 5 close to the equipment foundation 2. In this embodiment, four connecting pads 11 are provided. A connecting hole 111 is opened on the connecting pad 11. The connecting hole 111 is used to penetrate the bolts connecting the equipment foundation 2 and the connecting block 5.

[0039] Reference Figure 6 、 7 The connecting block 5 is composed of two identical, detachably connected housings 10, forming an annular outer shell with equal openings at both ends. The heat-resistance block 13 is equal in length to the connecting block 5. In this embodiment, a connecting side plate 12 is provided on the outside of the housing 10. The connecting side plate 12 has side plate connecting holes 121 formed therein for receiving bolts that connect the two housings 10.

[0040] Reference Figure 8 , a plurality of support pads 4 are also provided on the equipment foundation 2, and the height of the support pads 4 is equal to the height of the middle insulation layer 6. Since the pressure-bearing capacity of the mounting member 3 itself in Example 1 is weak, the height of the support pads 4 is greater than or equal to the height of the mounting member 3, and the support pads 4 directly support the upper equipment.

[0041] There are two ways to arrange the support pad 4 and the connecting block 5:

[0042] The first one: reference Figure 8 When the number of the support blocks 4 is the same as the number of the mounting members 3 , the support blocks 4 and the mounting members 3 are staggered, and two adjacent support blocks 4 are located on different horizontal lines.

[0043] The second type: reference Figure 9 When the number of support blocks 4 is less than the number of mounting members 3, one support block 4 and two mounting members 3 form an installation group and are arranged along the length direction of the equipment foundation.

[0044] During construction, designers can determine the number of mounting parts 3 and select the arrangement of mounting parts 3 and supporting pads 4 based on the size of the anti-corrosion and thermal insulation layer 8, project costs and the upper load of the anti-corrosion and thermal insulation layer 8 to ensure sufficient support for the upper equipment and ensure the safety of the upper equipment.

[0045] Reference Figure 7 The heat-blocking block 13 is located inside the connecting block 5. At least two integrally formed self-locking protrusions 16 are provided on the outer side of the heat-blocking block 13. The housing 10 is provided with self-locking grooves that cooperate with the self-locking protrusions 16. In this embodiment, there are two self-locking protrusions 16, each having a trapezoidal cross-sectional area. This trapezoidal shape allows for bidirectional locking in the axial direction, reducing axial movement of the self-locking protrusions 16. The angle between the hypotenuse of the self-locking protrusion 16 and its height is smaller than the friction angle, ensuring that the heat-blocking block 13 and the annular housing do not shift relative to each other in the axial direction.

[0046] One end of the connecting rod 7 is detachably connected to the thermal block 13, and the other end extends through the insulation layer 14 and the embedded plate 9. In this embodiment, at least two coaxially disposed deformable members 15 are truncated cone-shaped and internally provided with a plurality of connecting grooves that mate with the deformable members 15. The deformable members 15 are threadedly connected to the connecting rod 7. The angle between the circumferential hypotenuse of the deformable members 15 and the axial height of the deformable members 15 is less than the friction angle, thereby ensuring that the deformable members 15 and the thermal block 13, and thus the annular housing, are not displaced axially relative to each other.

[0047] Reference Figure 2 A first waterproof layer 17 is provided between the equipment foundation 2 and the insulation layer 14. This first waterproof layer 17 wraps around the outside of the equipment foundation 2 and fills the gap between them, helping to reduce heat loss and water erosion. The first waterproof layer 17 comprises a vapor barrier 201 and a bottom waterproof layer 202. In this embodiment, the vapor barrier 201 utilizes an alkali-resistant aluminum foil-faced, fiberglass-backed, self-adhesive modified asphalt vapor barrier membrane, while the bottom waterproof layer 202 utilizes a PE-faced, fiberglass-backed, modified asphalt self-adhesive waterproof membrane.

[0048] Reference Figure 3 A second waterproof layer 19 is provided between the insulation layer 14 and the embedded plate 9. The second waterproof layer 19 includes a first waterproof layer 81, a second waterproof layer 82, an isolation layer 83, and a protective layer 84. The second waterproof layer 19 can fill the gap between the insulation layer 14 and the embedded plate 9, further strengthening the thermal insulation effect, so that the structural roof has a strong thermal insulation capacity. In this embodiment, the first waterproof layer 81 is made of a PE-faced glass fiber reinforced modified asphalt self-adhesive waterproof membrane, the second waterproof layer 82 is made of a rock board-faced glass fiber reinforced polyurethane modified asphalt waterproof membrane, the isolation layer 83 is made of lime mortar, and the protective layer 84 is made of fine stone concrete. A steel mesh is provided inside the protective layer 84. The protective layer 84 can provide force support for the construction of the upper embedded plate 9 and can also provide protection for the lower insulation layer 14 and waterproof layer to prevent damage from external forces.

[0049] Reference Figure 1 The width of the second waterproof layer 19 is greater than the width of the equipment foundation 2 , and the side insulation layer 203 is located between the equipment foundation 2 and the second waterproof layer 19 .

[0050] The implementation principle of the first embodiment of the present invention is as follows: the construction includes the following steps:

[0051] 1) Laying the first waterproof layer 17 on the equipment foundation 2;

[0052] 2) Assemble the mounting member 3. The assembly steps are as follows: first, mechanically place the deformable member 15 inside the heat-resistance block 13. Then, place the self-locking protrusion 16 of the heat-resistance block 13 into the self-locking groove of the housing 10. Bolts are then used to connect the two housings 10 through the connecting side plates 12, thereby connecting the heat-resistance block 13 to the connecting block 5. Then, the mounting member 3 and the support pad 4 are installed in the appropriate arrangement, and the connecting rod 7 is connected to the heat-resistance block 13, completing the assembly of the mounting member 3.

[0053] 3) Cut and punch holes in the middle insulation layer 6 according to the arrangement of the mounting members 3 and the support blocks 4, so that the mounting members 3 and the support blocks 4 are embedded in the middle insulation layer 6;

[0054] 4) Install the anti-corrosion insulation layer 8;

[0055] 5) Install the side insulation layer 203;

[0056] 6) Installing the second waterproof layer 19;

[0057] 7) Install the embedded plate 9.

[0058] In this embodiment, the mounting member 3 connects the equipment foundation 2 to the insulation layer 14 and embedded plate 9, avoiding the thermal bridge effect caused by direct anchor bolt connection, thereby achieving a "zero thermal bridge" effect. Furthermore, the first and second waterproof layers 17 and 19 fill the connection gap, providing both waterproofing and insulation, further enhancing the thermal insulation effect of this joint.

[0059] Example 2

[0060] Reference Figure 10 The difference between Example 2 and Example 1 is that the connecting block 5 is integral, so that the connecting block 5 itself has a strong bearing capacity, the heat-resistant block 13 is located at one end of the connecting block 5, and the connecting rod 7 passes through the end of the connecting block 5 away from the heat-resistant block 13 and is connected to the heat-resistant block 13. In this embodiment, the height of the connecting block 5 is equal to the thickness of the middle insulation layer 6.

[0061] The end of the connecting rod 7 is provided with a detachably connected tensile connector 21. The cross-sectional area of the tensile connector 21 is larger than the cross-sectional area of the connecting rod 7. The tensile connector 21 further increases the tensile bearing capacity of the connecting block 5. In this embodiment, the tensile connector 21 is threadedly connected to the connecting rod 7.

[0062] The tensile connector 21 is detachably connected to the heat-resistant block 13. In this embodiment, the heat-resistant block 13 includes a first part 20 and a second part 18 that are separately arranged. An installation groove is provided at one end of the second part 18. The first part 20 is flat and the tensile connector 21 is located in the installation groove. The tensile connector 21 at one end of the connecting rod 7 is located in the installation groove of the first part 20.

[0063] The outer side of the connecting rod 7 is covered with a heat-insulating sleeve 22, part of which is located in the heat-resisting block 13, and the rest is located in the connecting block 5. The heat-insulating sleeve 22 can prevent the connecting rod 7 from directly contacting the connecting block 5, and more comprehensively isolate the connecting rod 7 and the connecting block 5, thereby eliminating the thermal bridge effect.

[0064] The implementation principle of Example 2 is different from that of Example 1 in that the assembly of the mounting member 3 is performed. First, the second part 18 is installed with the connecting block 5, and then the tensile connector 21 is connected with the connecting rod 7. After that, the thermal insulation sleeve 22 is sleeved on the outside of the connecting rod 7, and then the assembled tensile connector 21, connecting rod 7 and thermal insulation sleeve 22 are connected with the second part 18, so that the tensile connector 21 is located in the installation groove, part of the thermal insulation sleeve 22 is located in the second part 18, and the rest is located in the connecting block 5; then the tensile connector 21 is wrapped in the heat-resistant block 13 using the first part 20, and finally the connecting block 5 is connected to the equipment foundation 2 using bolts through the connecting pad 11, thereby realizing the installation of the mounting member 3.

[0065] The difference between the second embodiment and the first embodiment is that the mounting member 3 in the second embodiment itself has a strong compressive bearing capacity, so the supporting pad 4 can be omitted.

[0066] In this embodiment, the mounting member 3 can not only prevent the connection rod 7 from contacting the equipment foundation 2, but also play a good heat insulation role to achieve the purpose of "0" thermal bridge, but also has a strong bearing capacity to ensure the stability and safety of the equipment installation.
