Description

Technical Field

[0001] This application belongs to the technical field of bridge construction, and more specifically, relates to a device for filling the holes of tie rods in piers. Background Technology

[0002] The pier body is the main intermediate support structure of a multi-span bridge. The pier body uses steel formwork, and the flat surface uses high-strength threaded steel + PVC pipe tie rods. After demolding, the tie rod holes need to be sealed.

[0003] Currently, the sealing of tie rod holes usually involves using a manual grouting gun to inject grout into the tie rod hole. When using this method, the operator needs to insert the nozzle of the grouting gun into the tie rod hole and push the piston rod to inject grout.

[0004] Throughout the grouting process, the operator needs to continuously push the piston rod, which can easily cause gaps to appear between the nozzle of the grouting gun and the opening of the tie rod hole due to insufficient force or other factors, resulting in grout leakage. Utility Model Content

[0005] The purpose of this application is to provide a filling device for the tie rod hole of the pier body, so as to solve the technical problem in the prior art that gaps easily appear between the nozzle of the grouting gun and the opening of the tie rod hole during grouting, causing grout leakage.

[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide a pier reinforcement hole filling device, including a grouting gun body with a nozzle, the reinforcement hole filling device further including: A positioning ring, coaxially sleeved on the grouting gun body and located near the nozzle; the positioning ring has a plane for conforming to the structural surface around the tie rod hole; and An adjustment component is disposed on the grouting gun body and connected to the positioning ring. The adjustment component is used to drive the positioning ring to slide along its own axis. In one possible implementation, based on the above technical solutions, the adjustment component includes: A sliding ring is slidably sleeved on the grouting gun body; The rotating sleeve is coaxially fitted onto the grouting gun body and rotatably connected to the sliding ring; and The threaded ring is coaxially fixed on the grouting gun body and threadedly connected to the rotating sleeve.

[0007] In conjunction with the above technical solutions, in one possible implementation, the adjustment component further includes: An adjusting bolt is threadedly connected to the sliding ring, with one end of the adjusting bolt passing through the sliding ring and pressing against the grouting gun body.

[0008] In one possible implementation, based on the above technical solutions, a guide groove is provided on the outer side of the grouting gun body along its own axial direction, and one end of the adjusting bolt is located in the guide groove.

[0009] In one possible implementation, based on the above technical solutions, the guide groove is set with an opening at one end facing the muzzle.

[0010] In one possible implementation, based on the above technical solutions, one adjusting bolt and one guide groove are provided on each side of the grouting gun body.

[0011] In one possible implementation, based on the above technical solutions, the muzzle end is detachably connected to an extension tube.

[0012] In one possible implementation, based on the above technical solutions, the extended tube is threadedly connected to the muzzle end.

[0013] The beneficial effects of the grouting device for reinforcing bar holes provided in this application are as follows: Compared with the prior art, during grouting operations, this application ensures that the positioning ring is in contact with the structural surface surrounding the reinforcing bar hole while the grouting gun is inserted into the hole. At this time, the grouting gun body remains perpendicular to the structural surface, ensuring a fixed relative position between the grouting gun and the reinforcing bar hole. This reduces the operational difficulty for workers and prevents grout leakage. Furthermore, due to differences in the position of the structural surface surrounding different reinforcing bar holes or the varying grouting depths, the positioning ring can be flexibly adjusted according to actual conditions using the adjustment component, allowing it to better fit the structural surface around the reinforcing bar hole, further improving the grouting effect and quality.

[0017] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain this application and are not intended to limit this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] It should be further noted that the accompanying drawings and embodiments of this application mainly describe the concept of this application. Based on this concept, some specific forms and arrangements of connection relationships and positional relationships may not be fully described. However, under the premise that those skilled in the art understand the concept of this application, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0019] When a component is referred to as "connected to" or "set on" another component, it can be directly on or indirectly on that other component.

[0020] The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself. The terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0022] The present application provides a description of a device for filling the reinforcing bar holes in a pier.

[0023] like Figure 1 and Figure 2 As shown, one embodiment of this application provides a grouting gun body for filling tie rod holes, including a grouting gun body 1, a positioning ring 2, and an adjusting component 3; one end of the grouting gun body 1 has a nozzle 11; the positioning ring 2 is coaxially sleeved on the grouting gun body 1 and located near the nozzle 11; the positioning ring 2 has a plane for conforming to the structural surface around the tie rod hole; the adjusting component 3 is disposed on the grouting gun body 1 and connected to the positioning ring 2, and the adjusting component 3 is used to drive the positioning ring 2 to slide along its own axial direction.

[0024] This embodiment provides a pier tie rod hole filling device. Compared with the prior art, during grouting operations, when the nozzle 11 is inserted into the tie rod hole, the positioning ring 2 is made to fit against the structural surface around the tie rod hole. At this time, the grouting gun body 1 remains perpendicular to the structural surface, ensuring that the relative position of the grouting gun and the tie rod hole is fixed. This reduces the operational difficulty for operators and prevents grout leakage. Furthermore, due to the different positions of the structural surfaces around the tie rod holes or the different grouting depths of the tie rod holes, the position of the positioning ring 2 can be flexibly adjusted according to the actual situation by adjusting the component 3, making it better fit against the structural surface around the tie rod hole, further improving the grouting effect and quality.

[0025] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The adjusting assembly 3 includes a sliding ring 31, a rotating sleeve 32, and a threaded ring 33; the sliding ring 31 is slidably sleeved on the grouting gun body 1; the rotating sleeve 32 is coaxially sleeved on the grouting gun body 1 and rotatably connected to the sliding ring 31; the threaded ring 33 is coaxially fixed on the grouting gun body 1 and threadedly connected to the rotating sleeve 32.

[0026] When the position of the positioning ring 2 needs to be adjusted, the rotating sleeve 32 is turned. Due to the threaded engagement, the rotating sleeve 32 will move along the axial direction of the threaded ring 33, thereby causing the sliding ring 31 and the positioning ring 2 to slide together. The threaded transmission method has high precision and stability, and can more accurately control the movement distance of the positioning ring 2, so that the positioning ring 2 can more precisely fit the structural surface around the tie rod hole, effectively preventing slurry leakage.

[0027] Meanwhile, the threaded drive also has a self-locking function, which can keep the position of the positioning ring 2 stable after it is adjusted to the appropriate position, thus ensuring the smooth progress of the grouting operation.

[0028] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The adjusting assembly 3 also includes an adjusting bolt 34, which is threadedly connected to the sliding ring 31. One end of the adjusting bolt 34 passes through the sliding ring 31 and abuts against the grouting gun body 1.

[0029] After adjusting the positioning ring 2 to the appropriate position, tighten the adjusting bolt 34 to make it press against the grouting gun body 1. This can prevent the sliding ring 31 from sliding due to external force or vibration during the grouting process, thereby ensuring that the position of the positioning ring 2 remains fixed and further improving the stability and reliability of the device.

[0030] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: A guide groove 12 is provided on the outer side of the grouting gun body 1 along its own axial direction, and one end of the adjusting bolt 34 is located in the guide groove 12.

[0031] The cooperation between the adjusting bolt 34 and the guide groove 12 can guide the sliding ring 31. There is no need to fix the slider inside the sliding ring 31. The adjusting bolt 34 can both fix the sliding ring 31 and guide it, which improves the convenience and efficiency of operation.

[0032] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The guide groove 12 is set with an opening at one end facing the muzzle 11.

[0033] In actual construction, if the adjustment component 3 needs to be repaired or replaced, the opening allows the adjustment bolt 34 to smoothly enter and exit the guide groove 12 from the opening end of the guide groove 12, which improves the ease of installation and disassembly of the adjustment component 3.

[0034] like Figures 1 to 2As shown, this application provides another specific implementation method based on the above-described implementation method as follows: One adjusting bolt 34 and one guide groove 12 are provided on each side of the grouting gun body 1.

[0035] The adjusting bolts 34 and guide grooves 12 on both sides can simultaneously constrain and adjust the sliding ring 31 and the positioning ring 2, making the positioning ring 2 more evenly stressed during sliding, avoiding tilting or shaking caused by unilateral stress, and further improving the sealing performance and effect of grouting.

[0036] Meanwhile, the symmetrical arrangement also increases the strength and reliability of the adjustment component 3, enabling it to withstand greater external forces and vibrations, and reducing the possibility of the adjustment component 3 malfunctioning during use.

[0037] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: An extension tube 4 is detachably connected to the end of the muzzle 11.

[0038] In actual bridge construction, the depth of the tie rod hole may vary depending on different design requirements or construction conditions. When the grouting position is deep, the nozzle 11 can be lengthened by installing the extension pipe 4. The detachable connection method allows for the selection of extension pipes 4 of different lengths for installation according to the actual situation, further enhancing the versatility and adaptability of the device.

[0039] like Figure 1 and Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The extension tube 4 is threaded to the end of the muzzle 11.

[0040] The threaded connection has good self-locking performance. After the extension tube 4 is installed, it can ensure that the extension tube 4 is tightly connected to the end of the nozzle 11 and will not loosen or fall off due to pressure or vibration during the grouting process. This allows the grout to be injected stably through the extension tube 4 into the tie rod hole, avoiding grout leakage or uneven grouting caused by loose connection.

[0041] Meanwhile, the installation and disassembly of threaded connections are relatively simple. Operators only need to rotate the extension tube 4 to complete the installation or disassembly without the need for complicated tools or equipment, which improves the convenience and efficiency of operation.

[0042] Specifically, when it is not necessary to lengthen the muzzle 11, an extension tube 4 with the same thread length as the muzzle 11 can be screwed onto the muzzle 11 so that the end face of the muzzle 11 is flush with the end face of the extension tube 4, thereby achieving the protective effect of the extension tube 4 on the thread of the muzzle 11.
