[0002] In modern engineering construction, prestressing technology is widely used in large structures such as bridges and high-rise buildings to improve their load-bearing capacity and durability. As key equipment for implementing prestressing technology, the performance and reliability of prestressing tools directly impact the quality and safety of projects.

[0003] At present, the existing prestressed tools have some shortcomings: on the one hand, the waterproofing measures of traditional prestressed tools are not perfect, the waterproofing process is complicated, and it is difficult to ensure that the anchor bars can be effectively protected in various environments. Some prestressed tools require additional waterproofing after installation, which not only increases the construction time, but may also affect the waterproofing effect due to improper treatment. On the other hand, the connection structure of many prestressed tools is relatively simple and difficult to flexibly adjust to adapt to anchor bars of different thicknesses. This may result in the need to prepare tools of various specifications in actual use, increasing engineering costs and construction difficulty. Therefore, a prestressed tool that can be grouted and waterproofed is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a prestressed tool that can be grouted for waterproofing, aiming to improve the problem in the existing technology that some prestressed tools require additional waterproofing treatment after installation, which not only increases the construction time but may also affect the waterproofing effect due to improper treatment.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a prestressed grouting and waterproofing tool, comprising an anchor plate 1, the inner wall of which is fixedly connected multiple groups of anchor bars 2. The inner wall of the top of the anchor plate 1 is provided with three groups of guide grooves a3. The three groups of guide grooves a3 allow a low-concentration polyurethane solution to be injected into the tool when it is installed on the ground, allowing the solution to flow along the guide grooves a3 into the location of the anchor bars 2. The low-concentration polyurethane solution is a prior art liquid containing a polyurethane polymer, typically formed by dissolving a polyurethane material in a solvent at a certain ratio. Polyurethane is a widely used polymer material due to its excellent mechanical properties, wear resistance, elasticity, and chemical resistance.

[0032] Reference Figure 2 and Figure 3The surface of the anchor 4 is provided with three groups of cavities, and the anchor bar 2 passes through and is slidably connected to the inner wall of the anchor bar 4 cavity. By providing the anchor 4 installed on the surface of the anchor bar 2, the anchor 4 can firmly clamp the anchor bar 2, and transmit the tension of the prestressed bar to the concrete and other structures to prevent the anchor bar 2 from slipping or loosening during use. The surface of the anchor bar 2 is detachably installed with the anchor 4 through the positioning component 6. The bottom end of the outer wall of the anchor 4 is provided with three groups of guide grooves b5. The guide grooves b5 have the same function as the guide grooves a3, and the guide grooves b5 are opened at the bottom end of the anchor 4, so that the injected low-concentration polyurethane solution can be diverted.

[0033] Reference Figure 3 and Figure 4 The positioning assembly 6 includes a rotating block 61. The anchor bar 2 passes through and is slidably connected to the inner wall of the positioning groove of the rotating block 61. The rotating block 61 can be rotated on the inner wall of the anchor 4, so that the empty groove of the anchor 4 can be misaligned with the positioning groove of the rotating block 61, and the position of the anchor bar 2 can be supported and fixed without having to use a gasket to install the anchor 4 on the outside of the anchor bar 2. Moreover, by rotating the rotating block 61, it can adapt to anchor bars 2 of different thicknesses. The rotating block 61 is rotatably connected to the inner wall of the anchor 4. An empty groove is opened on the surface of the anchor 4. The connecting block 62 is slidably connected to the inner wall of the empty groove of the anchor 4. The outer wall of the rotating block 61 is fixedly connected with the connecting block 62 The inner wall of the connecting block 62 is elastically connected to the plug block 65 through a limit spring 64. One end of the limit spring 64 is fixedly connected to the bottom end of the outer wall of the plug block 65, and the other end of the limit spring 64 is fixedly connected to the bottom end of the inner wall of the connecting block 62. The function of the limit spring 64 is to automatically reset the position of the plug block 65 after it is pulled downward. The plug block 65 is slidably connected to the inner wall of the connecting block 62. There are multiple groups of through holes at the top of the empty slot of the anchor 4. The top of the outer wall of the plug block 65 is plugged into the inner wall of the through hole. The plugging between the two allows the rotating block 61 to rotate on the inner wall of the anchor 4 to fix the position of the positioning support of anchor bars 2 of different thicknesses.

[0034] Reference Figure 4 Three groups of positioning grooves are provided on the surface of the rotating block 61. The inner walls of the positioning grooves of the rotating block 61 are fixedly connected to multiple groups of contact balls 63. The outer walls of the contact balls 63 are in contact with the surface of the anchor bar 2. The contact balls 63 are made of rubber. When the rotating block 61 rotates, the contact balls 63 are driven to contact the surface of the anchor bar 2, thereby increasing the friction force, so that the rotating block 61 and the anchor 4 can be firmly installed on the surface of the anchor bar 2.

[0035] Working principle: First, install the anchor pad 1 at the predetermined position, then pass the anchor bar 2 through the cavity of the anchor 4 and the inside of the rotating block 61. According to the thickness of the anchor bar 2, the plug block 65 can be pushed downward to move it on the inner wall of the connecting block 62, thereby disengaging from the through hole of the current position of the anchor 4, and rotating the connecting block 62 to drive the rotating block 61 to rotate synchronously. When the rotating block 61 rotates, the rotating block 61 and the hole of the anchor 4 can be misaligned, so that the position of the anchor bar 2 can be positioned by the rotating block 61, and the contact ball 63 can also be driven to contact the surface of the anchor bar 2 to increase friction. After adjusting the position, the limit spring 64 can automatically reset the position of the plug block 65 to connect with the through hole at the current position of the anchor 4, thereby fixing the rotating block 61 on the inner wall of the anchor 4 after rotating according to the position of the thickness of the anchor bar 2, thereby firmly installing the anchor 4 on the anchor bar 2.

[0036] When waterproofing is required, a low-concentration polyurethane solution is injected into the anchor plate 1. The solution flows along the guide grooves a3 and b5 to the location of the anchor bars 2, thereby achieving a waterproof grouting function.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
