Description

Technical Field

[0001] The utility model relates to a low-energy-consumption, high-strength, heat-insulating composite material anchoring piece, belonging to the technical field of building anchoring. Background Art

[0002] The main mechanical connection methods used in engineering are bolt connection, mechanical key connection, riveting connection, welding connection, rubber connection and bearing connection. At present, the mechanical connection methods of external wall insulation or prefabricated integrated wall in my country are mainly in the form of bolt connection and mechanical key connection. However, if metal connecting anchors are used, the insulation effect will be weakened due to cold bridges. If plastic and other materials are used to connect anchors, such as the existing plastic expansion bolts, the strength is not enough. After long-term use, the expansion strips will fatigue and plastic deformation will occur, resulting in reduced extrusion force, weakened anchor force of anchor bolts, and even the risk of disengagement. With the development of ultra-low energy consumption buildings in recent years, the insulation requirements have increased significantly, and the thickness of external wall insulation materials has increased significantly. The powerful destructive effect of wind load and negative pressure cannot be ignored. In order to ensure the safety of the system under unforeseen circumstances, a new type of low-energy consumption, high-strength and heat-insulating anchor is urgently needed. Summary of the invention

[0003] The purpose of the utility model is to solve the problem that the anchoring pieces used in the prior art have high energy consumption and safety risks.

[0004] In order to achieve the purpose of solving the above problems, the technical solution adopted by the utility model is to provide a low-energy consumption, high-strength and heat-insulating composite anchor, including a composite rod, and a self-tapping screw passes through the anchoring plate and penetrates into one end of the composite rod.

[0005] Preferably, a gripping groove is provided at the other end of the composite material rod.

[0006] Further preferably, the gripping groove is 20 mm long and 1-3 mm deep, so as to further improve the bite between the composite material rod and the wall and ensure that the concrete base and the composite material rod have a strong grip.

[0007] Preferably, the composite material rod is made of glass fiber reinforced polyurethane, glass fiber reinforced epoxy resin or glass fiber reinforced unsaturated polyester resin, which is easy to process and is durable and corrosion-resistant.

[0008] Preferably, the composite material rod has a tensile strength of not less than 500 MPa, and a tensile elastic modulus of not less than 30 GPa.

[0009] Preferably, the anchoring pressure plate is made of steel sheet with a thickness of 1-3 mm and a diameter of 50-80 mm.

[0010] Further preferably, the anchoring pressure plate is provided with a supporting portion and a shearing portion, and the shearing portion is 0.5 mm higher than the supporting portion to ensure that the anchor can still have a larger shearing area and shearing force after being tensilely deformed.

[0011] Further preferably, the shearing portion is provided with a plurality of through holes, i.e. the anchoring plate is hollowed out, for improving the adhesion of the mortar sealing both sides of the anchoring plate and enhancing the firmness of the mortar at the anchoring plate to ensure effective connection between the outer leveling layer and the base layer.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. Compared with traditional anchors made of plastic and other materials, the anchoring force of the utility model is stronger and not easy to fall out, and compared with traditional anchors made of metal and other materials, the thermal insulation performance is excellent.

[0014] 2. The utility model is applied to the thermal insulation integrated wall which is prefabricated in the whole factory or partially prefabricated and partially cast in situ. It not only allows the outer panels of the thermal insulation integrated wall to use other light materials besides concrete, but also eliminates the cold bridge problem of the traditional screw connection with the steel structure truss. It shortens the construction period, simplifies the construction method and reduces the overall cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the present invention more clearly understood, a preferred embodiment is described in detail with reference to the accompanying drawings as follows:

[0020] Example 1

[0021] like Figure 1 , 2As shown, the utility model provides a low-energy consumption, high-strength, heat-insulating composite anchor. A hole is opened at one end of the composite rod 1, and the diameter matches the diameter of the self-tapping screw 3. The self-tapping screw 3 is used to connect the anchor plate 2 to the hole at one end of the composite rod 1 to form an integral connection anchor. A gripping groove 11 with a length of about 20 mm is opened about 20 mm inward from the other end of the composite rod 1. The groove depth is about 1-3 mm, so as to ensure that the concrete base and the composite rod have a strong grip. The anchor plate 2 is provided with a support portion 21 and a shear portion 22. The shear portion 22 extends outward by 0.5 mm steps compared to the support portion 21, so that the anchor can have a larger shear area and shear force after being tensilely deformed. The shear portion 22 is provided with a through hole 23, so as to ensure that the outer leveling layer is effectively connected to the base.

[0022] Example 2

[0023] like Figure 3 As shown, the utility model is applied to the thermal insulation integrated wall which is prefabricated in the whole factory or partially prefabricated and partially cast in situ. It not only allows the outer panels of the thermal insulation integrated wall to use other light materials besides concrete, but also eliminates the cold bridge problem of the traditional screw connection with the steel structure truss. It shortens the construction period, simplifies the construction method and reduces the overall cost.

[0024] The production process is:

[0025] The outer page board and the insulation layer are bonded by an adhesive to form an integral outer page wallboard. The diameter of the hole at the preset position of the integral outer page wallboard matches the anchor of the utility model and is 1-2mm larger than the diameter of the anchor of the utility model. The anchor of the utility model is placed in the preset hole, and one end of the composite material rod 1 with the gripping groove 11 is exposed from the surface of the insulation layer, and the exposed length is about 50-150mm.

[0026] The processed outer wall panels with the anchors of the utility model are placed in the mold and poured with concrete (on-site pouring: the outer wall panels are used as the outer formwork, and inner formwork reinforcement ribs and through-screws are set. The composite rods 1 in the utility model can be set as inner formwork reinforcement ribs). After the concrete solidifies, the inner panel concrete base and the outer wall panels are effectively connected through the composite rods 1 connected with the anchoring plate 2 and the self-tapping screws 3, and then the wall installation is completed.

[0027] The above is only a preferred embodiment of the utility model, and is not any formal or substantial limitation of the utility model. It should be pointed out that ordinary technicians in this technical field can make some improvements and supplements without departing from the utility model, and these improvements and supplements should also be regarded as the protection scope of the utility model. Any technician familiar with this profession can make some changes, modifications and equivalent changes made by using the technical content disclosed above without departing from the spirit and scope of the utility model, which are all equivalent embodiments of the utility model; at the same time, any changes, modifications and evolutions of any equivalent changes made to the above embodiments based on the essential technology of the utility model are still within the scope of the technical solution of the utility model.
