Abstract
Description
Technical Field
[0001] This utility model belongs to the field of speed pad technology and relates to an anchoring pad. Background Technology
[0002] Suge mats are a type of flexible polymer material primarily used for pipe repair and urban flood control. Combining the flexibility, ductility, and corrosion resistance of thermoplastics, they effectively prevent the deterioration of concrete structures, extend the service life of buildings, and prevent leaks and seepage. Suge mats possess significant tensile and tear strength, allowing them to adapt to pipe deformation and ensuring that the repaired structural layer continues to function properly even under deformation.
[0003] The following technical problems were found in the existing technology: When using anchoring gaskets, when connecting the gaskets to the super pads by welding, the metal wires inside the gaskets are heated to melt the contact points between the gaskets and the super pads for welding. However, during the cooling process, the expansion coefficients of the gaskets and the metal wires are different, which generates shear stress and may lead to delamination or surface warping. Utility Model Content
[0004] The technical problem to be solved by this utility model is: when using anchoring gaskets, when connecting the gaskets to the super pads by welding, the metal wires inside the gaskets are heated to melt the contact points between the gaskets and the super pads for welding. However, during the cooling process, the expansion coefficients of the gaskets and the metal wires are different, which generates shear stress and may lead to delamination or surface warping.
[0005] The present invention discloses an anchoring gasket comprising a polymer base; an installation hole is provided inside the polymer base; a stress compensation component is provided inside the polymer base; and a welding observation component is provided inside the polymer base.
[0006] The stress compensation component includes a metal mesh; a compensation inclined plate is provided on the bottom inner side of the metal mesh; and an annular microgroove is provided on the top outer side of the polymer base, the annular microgroove being 0.5 mm wide and 1 mm deep.
[0007] The welding observation assembly includes an overflow hole; the overflow hole is located in the middle of the inner side of the polymer base; and an observation groove is provided on the top of the overflow hole.
[0008] The polymer base contains 25% glass fiber.
[0009] The surface of the metal mesh undergoes a plasma roughening process.
[0010] Compared with the prior art, the beneficial effects of this utility model are: during the cooling welding process, there is a significant difference in the coefficient of thermal expansion between the polymer base and the metal mesh, and the resulting shear stress may cause delamination or warping between the polymer base and the metal mesh. By using the compensation component and the observation component, the compensation inclined plate at the bottom of the metal mesh transforms the abrupt stress into a gradient stress field. At the same time, the annular microgroove serves as a stress release channel, reducing the influence of the stress device and further increasing the firmness and reliability of the connection between the speed pad and the polymer base.
[0011] Adding 25% glass fiber inside the polymer base makes the coefficient of thermal expansion of the polymer base closer to that of metal, further reducing the possibility of delamination or warping between the polymer base and the metal mesh due to thermal stress. At the same time, it improves the overall durability of the polymer base and increases the service life of the device. Attached Figure Description

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0022] Example 1
[0023] like Figure 1 - Figure 4 As shown, an anchoring pad includes a polymer base 1; the polymer base 1 has an installation hole 11 inside; the polymer base 1 has a compensation component inside; the polymer base 1 has an observation component inside, the compensation component includes a metal mesh 2; the inner bottom of the metal mesh 2 has a compensation inclined plate 21, the use of the compensation inclined plate 21 can form a gradual stiffness transition zone, so that the stress between the metal mesh 2 and the polymer base 1 changes from abrupt change to gradual change, and at the same time can guide the stress to be released along the tangential component, reducing the reverse peeling force. At the same time, when the polymer base 1 and the fastener pad are cooled and contracted, the setting of the compensation inclined plate 21 allows the metal mesh 2 to slip slightly, reducing the possibility of local stress exceeding the yield strength; the outer top of the polymer base 1 has an annular microgroove 22, the annular microgroove 22 is 0.5 mm wide and 1 mm deep, the annular microgroove 22 is set in a non-critical area on the outer side of the polymer base 1 for directional release of contraction stress, and the observation component includes an overflow hole 3; the overflow hole 3 is located in the middle of the inner side of the polymer base 1; the top of the overflow hole 3 has an observation groove 31.
[0024] During operation, the metal mesh 2 at the bottom of the polymer base 1 is first placed close to the area where the speed grid pad needs to be welded. Then, a handheld electromagnetic induction heating device is used to heat the metal mesh 2. As the metal mesh 2 heats up, the contact point between the speed grid pad and the polymer base 1 begins to melt and weld. During the welding process, some molten polymer is generated, which flows into the overflow hole 3. At this time, the operator observes the condition inside the overflow hole 3 through the observation groove 31 to judge the welding quality of the contact point between the speed grid pad and the polymer base 1. Simultaneously, the observation groove 31 set at the bottom of the metal mesh 2 and the outer side of the polymer base 1... In non-critical areas, annular microgrooves 22 are provided. During the welding process of melting and cooling the polymer base 1 and the metal mesh 2, there is a significant difference in the coefficient of thermal expansion between the polymer base 1 and the metal mesh 2. The resulting shear stress may cause delamination or warping between the polymer base 1 and the metal mesh 2. Through the use of compensation components and observation components, the compensation inclined plate 21 at the bottom of the metal mesh 2 transforms the abrupt stress into a gradient stress field. At the same time, the annular microgrooves 22 serve as stress relief channels, reducing the influence of stress devices and further increasing the strength and reliability of the connection between the speed pad and the polymer base 1.
[0025] Example 2
[0026] like Figure 1 - Figure 4 As shown, 25% glass fiber is added inside the polymer base 1, and a plasma roughening process is performed on the surface of the metal mesh 2.
[0027] During operation, adding 25% glass fiber inside the polymer base 1 makes the coefficient of thermal expansion of the polymer base 1 closer to that of metal, further reducing the possibility of delamination or warping between the polymer base 1 and the metal mesh 2 due to thermal stress. At the same time, it improves the overall durability of the polymer base 1 and increases the service life of the device. The plasma roughening process makes the surface of the metal mesh 2 rough, which increases the mechanical interlocking force between it and the plastic by 3 times, making the connection between the metal mesh 2 and the polymer base 1 tighter and stronger, further increasing the stability of the device.
