Description

Technical Field

[0001] The invention relates to the technical field of low-energy consumption buildings, and in particular to a multifunctional connector suitable for passive ultra-low energy consumption buildings and an installation method thereof. Background Art

[0002] Passive ultra-low energy buildings are a new type of building that can reduce building energy consumption and improve living experience by reducing heat exchange between indoors and outdoors and cooperating with HVAC equipment. This type of building needs to minimize the thermal bridge effect, otherwise it is easy to damage the building system insulation system, which in turn leads to increased building energy consumption.

[0003] HVAC pipes are one of the indispensable components of buildings. They are often connected to floor slabs or beams through seismic brackets or threaded hangers. In addition, holes must be opened directly at the bottom of the slabs or beams during connection. The connection speed is slow and it is difficult to control the weakening of the structural stress caused by cracks when opening holes.

[0004] In addition, when the threaded hangers or seismic brackets made of steel are directly connected to the plates or beams, the heat will be transferred along the threaded hangers or seismic brackets to the connection parts, such as basements, corridor structures or structures exposed to the outdoors, which are prone to thermal bridge effects.

[0005] Generally, a large number of threaded hangers or seismic brackets are required for buildings. The thermal bridge effect in a large number of parts will greatly weaken the thermal insulation effect of the building. Therefore, it is necessary to propose a thermal bridge connector that can be used to connect threaded hangers or seismic brackets, which is convenient for construction and suitable for passive ultra-low energy consumption buildings. Summary of the invention

[0006] In view of the problems existing in the prior art, the present invention provides a multifunctional connector suitable for a passive ultra-low energy consumption building and an installation method.

[0007] The present invention is achieved through the following technical solutions:

[0008] A multifunctional connector suitable for a passive ultra-low energy consumption building comprises an outer shell, a heat-resistant component and an anti-shear component, wherein the heat-resistant component is arranged inside the outer shell, and the heat-resistant component comprises an anti-thermal bridge sealing section, a force-holding section and a force-holding platform, wherein the force-holding section is provided with an installation groove, and the anti-thermal bridge sealing section and the force-holding platform are both embedded in the installation groove; the force-holding platform is used for connecting with an external connector; the anti-thermal bridge sealing section and the force-holding section are both made of rubber material; the anti-shear component passes through the outer shell and the force-holding section, and both ends extend out of the outer shell.

[0009] Preferably, the side surface of the force-holding platform is arranged in an inclined surface, and the cross-sectional area of ​​the force-holding platform gradually decreases from a side close to the anti-thermal bridge sealing section to a side far from the anti-thermal bridge sealing section.

[0010] Preferably, the angle between the inclined surface of the force-holding platform and its length axis is smaller than the friction angle.

[0011] Preferably, the force holding platform is provided with a force holding connection hole, and the force holding connection hole is used to connect with an external connecting piece.

[0012] Preferably, the distance from the centroid of the cross section of the anti-shear member to the height axis of the force-holding connection hole is less than or equal to the distance from the edge of the maximum cross section of the force-holding platform to the height axis of the force-holding connection hole.

[0013] Preferably, a gap is left between the anti-shear member and the force-bearing platform.

[0014] Preferably, a plurality of the anti-shear members are provided along the circumference of the shell; the anti-shear members are arranged in layers and at intervals, and each layer has at least two anti-shear members.

[0015] Preferably, the planes formed by the plurality of shear-resistant members in two adjacent layers are parallel; and the length axes of the shear-resistant members in two adjacent layers are perpendicular.

[0016] Preferably, some of the anti-shear parts are configured as pipes for installation of circuits or network cables.

[0017] A method for installing a multifunctional connector for a passive ultra-low energy consumption building, using a multifunctional connector suitable for a passive ultra-low energy consumption building, comprises the following steps:

[0018] S1, first embed the force-holding platform from the top of the force-holding section, and use the anti-thermal bridge blocking section and the top of the force-holding platform to block;

[0019] S2, embedding the force-holding section into the shell;

[0020] S3, the shear member is arranged to penetrate the shell and the bearing section, and the two ends extend out of the shell.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The multifunctional connector component suitable for passive ultra-low energy consumption buildings of the present invention has the function of preventing thermal bridges. The force-bearing section, the force-bearing platform and the outer shell cooperate with each other, so that the force-bearing section is in a bidirectional force state, which helps to prevent the force-bearing platform from escaping from the force-bearing section, thereby improving the bearing strength of the connector.

[0023] When in use, the anti-thermal bridge sealing section and the force holding section cooperate to fully wrap the force holding platform. The anti-thermal bridge sealing section and the force holding section are both made of rubber material. The rubber material has excellent heat insulation ability, thereby avoiding direct contact between the force holding platform and the outer shell, achieving a tight connection between the force holding platform and the outer shell, and avoiding air retention, thereby ensuring the anti-thermal bridge effect of the connecting piece and achieving the purpose of anti-thermal bridge.

[0024] The force-bearing section made of rubber material has the ability to deform and absorb energy, so that the connecting piece has the ability to resist earthquakes and dissipate energy.

[0025] The invention has a simple structure and can be widely used in engineering projects. Moreover, the connector of the invention only needs to be directly threaded later, so the construction speed is high. When in use, the connector only needs to be placed directly at a predetermined position above the template. However, in order to prevent the connector from slipping during concrete pouring, the outer shell can be connected to the steel bars in the plate or beam by electric welding.

[0026] Furthermore, the outer shell can prevent moisture in the concrete from directly contacting the bearing section, thereby avoiding corrosion of the connector during long-term use.

[0027] Furthermore, the angle between the inclined surface of the force-holding platform and its longitudinal axis is smaller than the friction angle, which can greatly reduce the tendency of the force-holding prism to be pulled out from under the force-holding section.

[0028] Furthermore, the force-bearing connection holes can facilitate the direct connection of connecting parts such as earthquake-resistant brackets or threaded hangers to the force-bearing platform, thereby greatly improving the construction speed.

[0029] Further, the shear member can reduce the bonding slip between the concrete and the shell, preventing the connector from coming out of the concrete after the demoulding. In addition, the outer surface of the shell can also be bonded with concrete, further preventing the connector from coming out of the concrete.

[0030] A certain gap is left between the shear member and the force-holding platform to ensure that part of the force-holding section between the shear member and the force-holding platform can be compressed and deformed, thereby dissipating energy, and thus making the connector of the present invention have a certain seismic resistance after being connected to the threaded hanger rod or the seismic support. At the same time, it can ensure that the force-holding platform and the shear member are not in direct contact, preventing the temperature from being transferred between the shear member and the force-holding platform, thereby realizing the anti-thermal bridge function.

[0031] Furthermore, the distance from the anti-shear member to the length axis of the force-holding connection hole is limited to ensure that even if the force-holding platform has a large tendency to separate from the bottom of the force-holding section, the anti-shear member can further support the force-holding platform to prevent the force-holding platform from separating from the force-holding section.

[0032] Furthermore, the anti-shear member provided on the pipe not only has the ability to increase the strength, but also has the function of protecting the circuit or network cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] 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.

[0043] Example 1

[0044] The present invention discloses a multifunctional connector suitable for passive ultra-low energy consumption buildings. Figure 1 , 2 , including a shell 1, a heat-resistant part and a shear-resistant part 5. In this embodiment, the shell 1 is a square thin-walled arrangement. The shell 1 can prevent the moisture in the concrete from directly contacting the bearing section 3, thereby avoiding corrosion of the connecting parts during long-term use.

[0045] The heat-resistant component comprises a heat-proof bridge blocking section 2, a force-holding section 3 and a force-holding platform 4. The force-holding section 3 is provided with a mounting groove, and the heat-proof bridge blocking section 2 and the force-holding platform 4 are both embedded in the mounting groove.

[0046] The side surface of the force holding platform 4 is arranged in an inclined surface, and the cross-sectional area of ​​the force holding platform 4 gradually decreases from the side close to the anti-thermal bridge sealing section 2 to the side far away from the anti-thermal bridge sealing section 2. The angle between the inclined surface of the force holding platform 4 and its length axis is smaller than the friction angle, which can greatly reduce the tendency of the force holding platform 4 to slip out from under the force holding section 3.

[0047] Reference Figure 2The force-holding platform 4 is provided with a force-holding connection hole 41, which can facilitate the force-holding platform 4 to be directly connected to an external connection piece. The force-holding connection hole 41 can facilitate the connection piece such as an anti-seismic bracket or a threaded hanger rod to be directly connected to the force-holding platform 4, thereby greatly improving the construction speed.

[0048] Reference Figure 3 , 4 The housing 1 is provided with a housing hole 11, which is used to connect the shear member 5. The holding section 3 is provided with an internal through hole 31, which is overlapped with the housing hole 11 to ensure that the shear member 5 can directly pass through the entire connector of the present invention.

[0049] The internal through hole 31 on the force-holding section 3 may not be pre-set, and when the shear-resistant member 5 passes through the entire connecting member, it is only necessary to use external force to directly pierce the force-holding section 3 .

[0050] The heat bridge blocking section 2 and the holding section 3 are both made of rubber material. The holding section 3 made of rubber material not only has the ability to deform and absorb energy, so that the connector has the ability to resist earthquakes and dissipate energy, but also has good thermal insulation performance, ensuring the effect of heat bridge prevention.

[0051] Reference Figure 5 , 6 , the shear member 5 penetrates the shell 1 and the bearing section 3, and both ends extend out of the shell 1. In this embodiment, the shear member 5 is a cold-drawn wire, a galvanized iron wire or a steel bar. The shear member 5 can reduce the bonding slip between the concrete and the shell 1, and prevent the connector from falling out of the concrete after demolding. The outer surface of the shell 1 can also be bonded with concrete to further prevent the connector from falling out of the concrete.

[0052] A gap is left between the shear member 5 and the force-bearing platform 4 to ensure that part of the force-bearing section 3 between the shear member 5 and the force-bearing platform 4 can be compressed and deformed, thereby dissipating energy, so that the connecting piece of the present invention has a certain seismic resistance regardless of whether it is connected to a threaded hanger rod or a seismic support.

[0053] Multiple shear members 5 are provided along the circumference of the shell 1 . The shear members 5 are arranged in layers and at intervals. Each layer has at least two shear members 5 . In this embodiment, two layers of shear members 5 are provided, and each layer has two shear members 5 .

[0054] The planes formed by the plurality of shear members 5 of two adjacent layers are parallel; the length axes of the shear members 5 of two adjacent layers are perpendicular.

[0055] The distance from the centroid of the cross section of the shear member 5 to the height axis of the force-holding connection hole 41 is less than or equal to the distance from the edge of the maximum cross section of the force-holding platform 4 to the height axis of the force-holding connection hole 41. The distance from the shear member 5 to the length axis of the force-holding connection hole 41 is limited to ensure that even if the force-holding platform 4 has a tendency to detach from the lower side of the force-holding section 3, the shear member 5 can further support the force-holding platform 4 to prevent the force-holding platform 4 from detaching from the force-holding section 3.

[0056] A method for installing a multifunctional connector for a passive ultra-low energy building, wherein each component is prefabricated in a factory, comprising the following steps:

[0057] S1, first embed the force-holding platform 4 from above the force-holding section 3, and use the anti-thermal bridge blocking section 2 and the top of the force-holding platform 4 to block;

[0058] S2, embedding the force-holding section 3 into the housing 1;

[0059] S3, the shear-resistant member 5 is arranged to penetrate the shell 1 and the force-bearing section 3, and both ends extend out of the shell 1.

[0060] A method for using a multifunctional connector for a passive ultra-low energy consumption building comprises the following steps:

[0061] S1, after the formwork is set up and before the concrete is poured, the connector of the present invention is placed at a predetermined position, and whether to fix the connector of the present invention can be selected according to the working conditions;

[0062] S2, after pouring concrete, the external connector is directly threadedly connected to the force-bearing connector hole 41 on the force-bearing platform 4.

[0063] Example 2

[0064] Reference Figure 7 , 8 The difference between Example 2 and Example 1 is that part of the anti-shear member 5 is set as a pipe for installing a circuit or a network cable. The anti-shear member 5 set in the form of a pipe not only has the ability to improve the strength of the connector of the present invention, but also has the function of protecting the circuit or the network cable.

[0065] The multifunctional connector component suitable for passive ultra-low energy consumption buildings of the present invention has the function of preventing thermal bridges. Through the mutual cooperation of the force-holding section 3, the force-holding platform 4 and the outer shell 1, the force-holding section 3 is in a bidirectional force state, which helps to prevent the force-holding platform 4 from escaping from the force-holding section 3, thereby improving the bearing strength of the connector.
