Description

Technical Field

[0001] The utility model relates to the field of anchor plates, in particular to a high-strength prestressed anchor plate structure. Background Art

[0002] Anchor plate, commonly used building curtain wall embedded parts are of two types: flat plate and groove shape. Among them, flat plate embedded parts are the most widely used. The anchor plate of the flat plate embedded parts is buried in the concrete through the steel strand connected to it. When installing and using the anchor plate, it is usually necessary to cooperate with the clip. The clip is wrapped around the surface of the steel strand and passed through the anchor hole of the anchor plate, and the steel strand is squeezed and fixed using the wedge-shaped clip and the anchor hole.

[0003] However, almost all anchor plates on the market are made of carbon steel. Due to its good strength and hardness, it can ensure the stable clamping of the clip when the steel strand is installed. However, as the usage time increases, the force applied by the clip on the inside of the anchor hole for a long time will cause the anchor plate to deform, thereby affecting the service life of the anchor plate. Utility Model Content

[0004] The main purpose of the utility model is to provide a high-strength prestressed anchor plate structure, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a high-strength prestressed anchor plate structure, including an anchor plate body, the anchor plate body is made of carbon steel, a plurality of cylindrical mounting holes are opened on the surface of the anchor plate body, a sleeve is fixedly and movably installed inside the mounting hole, the sleeve is made of titanium alloy, the inner side of the sleeve is set as a truncated cone-shaped anchor hole, and the sleeve is installed inside the mounting hole through a connecting assembly.

[0006] The connecting assembly includes a support ring, the inner diameter of the support ring is adapted to the minimum inner diameter of the anchor hole, the outer diameter of the support ring is adapted to the inner diameter of the mounting hole, the support ring is fixedly installed inside the mounting hole, the support ring and the anchor plate body are an integrally formed structure, and the bottom of the sleeve is against the surface of the support ring.

[0007] A limiting component is arranged inside the sleeve and the mounting hole to prevent the sleeve from rotating.

[0008] The limiting assembly comprises a limiting groove, the limiting groove is arranged on the surface of the sleeve, a limiting rod is fixedly installed inside the mounting hole, the limiting rod is fixed on the surface of the supporting ring, and the limiting rod is movably installed inside the limiting groove.

[0009] The limiting groove is configured as an inclined groove, the inclination of which is the same as that of the anchor hole, and is opened from the bottom of the sleeve to the middle position.

[0010] There are a plurality of limit grooves, which are arranged in an annular shape on the surface of the sleeve.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. In the utility model, by providing a sleeve and a mounting hole, when the clip is against the inside of the sleeve, since the yield strength of the titanium alloy is much greater than that of carbon steel, the time required for its deformation will be longer, and since the surface of the sleeve is cylindrical, it will not cause extrusion to the inner wall of the mounting hole, reducing damage to the anchor plate body, making the overall service life longer, and since the price of titanium alloy is much higher than that of carbon steel, its manufacturing cost is lower than that of the titanium alloy anchor plate body.

[0013] 2. In the utility model, by setting a limit groove and a sleeve, there are multiple limit grooves, which are arranged in a ring shape on the surface of the sleeve. Since the cost of titanium alloy is relatively high, the limit groove is opened on the surface of the sleeve to reduce the manufacturing cost. Since the limit groove is set as an inclined groove, its inclination is the same as the inclination of the anchor hole, and it is opened from the bottom of the sleeve to the middle position. When installing the sleeve, it is directly inserted into the interior of the installation hole, which will not affect the yield strength of the titanium alloy. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, a high-strength prestressed anchor plate structure includes an anchor plate body 1, the anchor plate body 1 is made of carbon steel, the yield strength of carbon steel can reach 260MPa, a plurality of cylindrical mounting holes 2 are opened on the surface of the anchor plate body 1, a sleeve 3 is fixedly and movably installed inside the mounting hole 2, the sleeve 3 is made of titanium alloy, the yield strength of titanium alloy is between 716-2770MPa, the inner side of the sleeve 3 is set as a truncated cone-shaped anchor hole 4, which is adapted to the shape of the clip, and the steel strand is locked by a wedge-shaped structure, and the sleeve 3 is installed inside the mounting hole 2 through a connecting assembly to prevent the sleeve 3 from pulling the steel strand.

[0021] When the traditional anchor plate body 1 is in use, its clip is pulled and squeezed by the steel strand, so it will directly press against the inside of the anchor plate body 1, so that the anchor plate body 1 will be deformed within a certain period of time, and the clamping force of the clip is insufficient. However, when the clip presses against the inside of the sleeve 3, since the yield strength of the titanium alloy is much greater than that of carbon steel, it will take a longer time for it to deform. Moreover, since the surface of the sleeve 3 is cylindrical, it will not squeeze the inner wall of the mounting hole 2, thereby reducing damage to the anchor plate body 1 and extending the overall service life.

[0022] The connecting assembly includes a support ring 5, which has a certain thickness and thus has a strong supporting force. The inner diameter of the support ring 5 is adapted to the minimum inner diameter of the anchor hole 4, and the outer diameter of the support ring 5 is adapted to the inner diameter of the mounting hole 2. The support ring 5 is fixedly installed inside the mounting hole 2. The support ring 5 and the anchor plate body 1 are an integrally formed structure to ensure the connection strength between the support ring 5 and the anchor plate body 1. The bottom of the sleeve 3 is against the surface of the support ring 5. At this time, when installing the sleeve 3, it is only necessary to place the sleeve 3 inside the mounting hole 2. The installation method is simple and the structure is also very simple, and does not affect the strength of the anchor plate body 1 itself.

[0023] The sleeve 3 and the interior of the mounting hole 2 are provided with a limit assembly to prevent the sleeve 3 from rotating.

[0024] The limit assembly includes a limit groove 6, which is opened on the surface of the sleeve 3. Due to the high cost of titanium alloy, opening the limit groove 6 on the surface of the sleeve 3 can reduce the manufacturing cost, and at the same time will not affect the yield strength of the titanium alloy. The interior of the mounting hole 2 is fixedly installed with a limit rod 7, and the limit rod 7 is fixed on the surface of the support ring 5. The limit rod 7 is movably installed inside the limit groove 6 to ensure that the sleeve 3 will not rotate during use, thereby preventing it from driving the steel strand to rotate, thereby affecting the use strength of the steel strand.

[0025] The limiting groove 6 is configured as an inclined groove, the inclination of which is the same as that of the anchor hole 4, and is opened from the bottom to the middle of the sleeve 3. When installing the sleeve 3, it is directly inserted into the interior of the mounting hole 2. Since the bottom thickness of the sleeve 3 is higher than the upper thickness, the strength of the entire sleeve 3 will not be affected.

[0026] There are multiple limiting grooves 6 , which are arranged in a ring shape on the surface of the sleeve 3 , which further reduces the production cost of the sleeve 3 and does not affect the use effect of the sleeve 3 .

[0027] It should be noted that the utility model is a high-strength prestressed anchor plate structure. When in use, the sleeve 3 is directly inserted and the limit rod 7 is installed inside the limit groove 6. When the clip is against the inside of the sleeve 3, since the yield strength of the titanium alloy is much greater than that of carbon steel, the time required for its deformation will be longer. Moreover, since the surface of the sleeve 3 is cylindrical, it will not squeeze the inner wall of the mounting hole 2, thereby reducing damage to the anchor plate body 1 and extending the overall service life.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
