Description

Technical Field

[0001] This utility model relates to the field of exterior wall construction technology, and in particular to an in-situ reinforcement combined anchor. Background Technology

[0002] External wall insulation systems are a general term for non-load-bearing insulation structures consisting of an insulation layer, a protective layer, and fixing materials (adhesives, anchors, etc.) that are suitable for installation on the exterior surface of exterior walls. External wall insulation systems can effectively reduce heat loss from buildings, improve building insulation performance, save significant amounts of energy, and provide residents with a comfortable environment, bringing numerous benefits.

[0003] As a crucial component of external wall insulation systems, anchors play an indispensable role. Existing anchors mostly consist of an expansion core and an expansion sleeve, or only an expansion sleeve. They rely on the friction generated by expansion or mechanical locking to connect the insulation system to the base wall, enhancing the safety and stability of the insulation system and effectively preventing the insulation layer from detaching.

[0004] Currently, many anchors use expansion sleeves made of plastic materials such as polyamide, polyethylene, and polypropylene to achieve good insulation and corrosion resistance. However, to increase the durability and stability of the anchors and ensure connection strength, the expansion cores in the anchors are often made of metal. The metal expansion core can create thermal bridges that facilitate heat transfer between indoor and outdoor environments, affecting the overall insulation performance of the system. Utility Model Content

[0005] The purpose of this invention is to provide an in-situ reinforced combined anchor that reduces thermal bridging after anchoring.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An in-situ reinforced composite anchor, comprising:

[0008] An expansion tube, wherein an expansion cavity is provided inside the expansion tube, and an expansion crack is provided on the outer wall of the expansion tube, the expansion crack penetrating the expansion cavity;

[0009] An anchor plate, the anchor plate comprising a main plate and a reinforcing plate;

[0010] The reinforcing tube has a reinforcing cavity inside. One end of the reinforcing tube is fixedly connected to the main plate, and the other end is fixedly connected to the expansion tube, thereby connecting the reinforcing cavity and the expansion cavity to each other.

[0011] An expansion core, which can be inserted into the reinforced cavity and the expansion cavity, and expand the expansion crack;

[0012] A reinforcing connector is provided, which can be inserted into the reinforcing cavity and fixedly connected inside the reinforcing cavity. One end of the reinforcing connector away from the expansion tube is connected to the reinforcing plate.

[0013] Furthermore, the expansion tube and the reinforcing tube are integrally formed or connected as a whole through the expansion core.

[0014] Furthermore, the expansion core includes a rod and a head, the head being connected to one end of the rod, and a limiting hole being provided at the end of the reinforcing tube. The expansion tube cavity and the reinforcing tube cavity are interconnected through the limiting hole, which allows the rod to pass through and intercepts the head.

[0015] Furthermore, the expansion core is a drill tail screw, and the expansion tube is a nylon tube.

[0016] Furthermore, when the expansion tube and the reinforcing tube are connected to each other through an expansion core, a snap-fit ​​portion is formed on the outer wall of the reinforcing tube along the axial direction of the expansion tube. The snap-fit ​​portion is arranged around the outer periphery of the expansion tube and abuts against the outer wall of the expansion tube.

[0017] Furthermore, the snap-fit ​​portion is annular.

[0018] Furthermore, after the expansion core opens the expansion crack and the reinforcing connector is inserted into the reinforcing cavity, there is a gap between the expansion core and the reinforcing connector.

[0019] Furthermore, the main disk and the reinforcing disk are parallel to each other, and a plurality of through holes are provided on the main disk and / or the reinforcing disk, and the through holes are evenly arranged along the circumference of the main disk.

[0020] Furthermore, a number of strip-shaped grooves are formed on the side of the main disk facing away from the expansion tube, and the length direction of the strip-shaped grooves is consistent with the radial direction of the main disk.

[0021] Furthermore, the inner wall of the reinforced cavity and the outer wall of the reinforced connector are provided with matching threads.

[0022] This utility model has the following beneficial effects:

[0023] 1. This anchor adopts a modular design. When installing the external wall insulation board, the expansion core can be used to expand the expansion tube, causing the expansion tube to deform and generate expansion force, thereby forming a firm connection with the wall. At the same time, in-situ reinforcement can be carried out through the reinforcement connector and reinforcement plate to enhance the fixing effect of the external wall insulation board and improve the stability of the external wall insulation system. The expansion core and reinforcement connector are set separately, which helps to reduce or even block the thermal bridging phenomenon caused by the use of anchors.

[0024] 2. The expansion tube and reinforcement tube adopt a split design, and different materials of expansion tube and reinforcement tube can be selected for anchoring according to the type of wall to be anchored, so as to better adapt to the anchoring needs of different walls. Furthermore, expansion tubes and reinforcement tubes of different lengths can be selected for combination and matching according to the thickness of the wall to be anchored, so as to meet the fixing needs of walls of different thicknesses.

[0025] 3. When this anchor is used to secure the insulation board, thermal bridging is relatively mild, which can effectively prevent heat loss through the thermal bridge area, ensuring the overall insulation performance. It can also prevent condensation and mold growth at the thermal bridge area, protecting the insulation board from moisture and corrosion, and extending its service life. For subsequent insulation board renovation and reinforcement, it can reduce the repair and replacement costs caused by condensation and mold. In addition, reducing thermal bridging helps to evenly distribute temperature stress, reducing the risk of cracks and deformation caused by temperature changes, and providing a better foundation for subsequent insulation board renovation and reinforcement.

Detailed Implementation

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1 , 2 As shown, this utility model discloses an in-situ reinforced combined anchor, including an expansion tube 100, an anchor plate 200, a reinforcing tube 300, an expansion core 400, and a reinforcing connector 500.

[0042] The expansion tube 100 has an expansion cavity 110 inside, and expansion cracks 120 are formed on the outer wall of the expansion tube 100. It also has barbed structures, inverted conical structures, and other structures to improve pull-out resistance. The expansion cracks 120 penetrate the expansion cavity 110 and are curved along the length of the expansion tube 100.

[0043] The anchor plate 200 consists of two parts: a main plate 210 and a reinforcing plate 220. The diameter of the main plate 210 is larger than that of the reinforcing plate 220, and correspondingly, the contact area between the main plate 210 and the object being fixed is larger than that of the reinforcing plate 220.

[0044] The reinforcing tube 300 has a reinforcing cavity 310 inside, with both ends of the reinforcing cavity 310 being through-holes. One end of the reinforcing tube 300 is fixedly connected to the main plate 210, which has a through hole corresponding to the reinforcing cavity 310. The other end of the reinforcing tube 300 is fixedly connected to the expansion tube 100, thereby connecting the coaxially arranged reinforcing cavity 310 and expansion cavity 110 to each other.

[0045] The expansion core 400 can pass through the main plate 210 and sequentially enter the reinforcing cavity 310 and the expansion cavity 110, thereby opening the expansion crack 120, causing the expansion tube 100 to deform and generate expansion force, thus forming a firm connection with the fixed object. In order to increase the durability and stability of the anchor and ensure the connection strength, the expansion core 400 is made of metal material.

[0046] The central axis of the reinforcing connector 500 and the expansion core 400 are on the same straight line. One end of the reinforcing connector 500, away from the expansion tube 100, is fixedly connected to the reinforcing plate 220, and the other end can be inserted into the reinforcing cavity 310. After insertion, the reinforcing connector 500 can be fixedly connected inside the reinforcing cavity 310 and fixedly connected together with the reinforcing tube 300. Together with the reinforcing plate 220, it can achieve in-situ reinforcement, enhance the fixing effect of the anchor, and improve the stability of the anchor. In this embodiment, the inner wall of the reinforcing cavity 310 and the outer wall of the reinforcing connector 500 are provided with matching threads, and the two can be fixed together by threaded connection.

[0047] Because the expansion core 400 and the reinforcing connector 500 are separate components, the thermal bridging effect after the anchor is anchored is relatively small. Preferably, the length of the reinforcing connector 500 is shorter than the length of the reinforcing cavity 310, so that after the expansion core 400 opens the expansion crack 120 and the reinforcing connector 500 penetrates the reinforcing cavity 310, there is a gap between the expansion core 400 and the reinforcing connector 500, with a distance L of approximately 8 mm. This gap between the expansion core 400 and the reinforcing connector 500 effectively blocks the thermal bridge. Alternatively, a non-metallic reinforcing connector 500 can be used for reinforcement, ensuring the fixing effect while reducing the thermal bridging effect.

[0048] As an example, the anchor is anchored in the building exterior wall structure 600 as follows: Figure 3 , 4 As shown. The exterior wall structure 600 includes, in sequence, a concrete wall 610, a plaster layer 620, an adhesive mortar layer 630, an integrated thermal insulation and decorative panel 640, a first crack-resistant mortar layer 650 with a mesh fabric, and a second crack-resistant mortar layer 660. The expansion tube 100 in the anchor is driven into the concrete wall 610 and, under the action of the expansion core 400, generates expansion force, thus firmly connecting with the concrete wall 610. The reinforcing tube 300 is basically inserted within the integrated thermal insulation and decorative panel 640. The main plate 210 is located within the first crack-resistant mortar layer 650 to disperse stress and improve pull-out resistance. The reinforcing connector 500 is locked into the reinforcing tube 300, and the reinforcing plate 220 is located within the second crack-resistant mortar layer 660 for in-situ reinforcement.

[0049] The main plate 210 and the reinforcing plate 220 are arranged parallel to each other. Several through holes are provided through the main plate 210 and / or the reinforcing plate 220, evenly distributed along the circumference of both plates. These through holes automatically form an effective fixing mechanism during anchor installation, enhancing the fixing effect. Similarly, several strip-shaped grooves 212 are formed on the side of the main plate 210 facing away from the expansion tube 100. The length direction of the strip-shaped grooves 212 is consistent with the radial direction of the main plate 210, which can improve the pull-out resistance of the anchor. Figure 5 , 6 As shown, in this embodiment, both the main disk 210 and the reinforcing disk 220 are provided with through holes, namely a first through hole 211 and a second through hole 221. On the main disk 210, the first through holes 211 are spaced apart by strip grooves 212.

[0050] The expansion tube 100 and reinforcing tube 300 can be integrally formed or separately installed to reduce the thermal bridging effect. For example... Figure 7-13 As shown, when the expansion tube 100 and the reinforcing tube 300 are installed separately, they can be connected into one unit by the expansion core 400. The expansion core 400 includes a rod 410 and a head 420, with the head 420 connected to one end of the rod 410. Correspondingly, the diameter of the expansion tube cavity 110 matches the thickness of the rod 410, and the diameter of the reinforcing tube cavity 310 matches the size of the head 420, being slightly larger than the expansion tube cavity 110. A limiting hole 320 is provided at the end of the reinforcing tube 300, located between the expansion tube cavity 110 and the reinforcing tube cavity 310, allowing them to communicate with each other. This limiting hole 320 allows the rod 410 to pass through while intercepting the head 420, enabling the expansion tube 100 and the reinforcing connector 500 to be connected together using the expansion core 400.

[0051] In this embodiment, the expansion core 400 is a drill tail screw, which has a strong drilling capability. After being locked into the expansion tube 100, the connection between it and the expansion tube 100 is more secure. The expansion tube 100 is a nylon tube, which has good chemical corrosion resistance and insulation properties, which helps to reduce and block thermal bridging.

[0052] Furthermore, when the expansion tube 100 and the reinforcing tube 300 are separately installed and connected to each other via the expansion core 400, a snap-fit ​​portion 330 is also provided on the outer wall of the reinforcing tube 300. The snap-fit ​​portion 330 extends along the axial direction of the expansion tube 100 and surrounds the outer periphery of the expansion tube 100. The snap-fit ​​portion 330 abuts against the outer wall of the expansion tube 100, which can assist in the quick connection of the expansion tube 100 and the reinforcing connector 500 during installation, and can strengthen the connection strength between the expansion tube 100 and the reinforcing connector 500 after installation. Preferably, the snap-fit ​​portion 330 is ring-shaped, which has a better effect.

[0053] In summary, this in-situ reinforced composite anchor has excellent anchoring effect, with high connection strength, good stability, and minimal or even complete thermal bridging after anchoring.

[0054] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims are within the scope of protection of the present invention.
