Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of grouting pipe overflow pipe fixing equipment, and in particular to a precast column grouting pipe overflow pipe fixing device. Background Technology
[0002] like Figure 1 As shown, during the fabrication of the precast column 100, grouting pipes 200 and overflow pipes 300 are pre-installed, with their openings protruding from the surface of the precast column. In traditional processes, grouting pipes 200 and overflow pipes 300 are typically tied to the stirrups of the precast column 100 or to the vertical main reinforcement bars within the precast column 100 using wire or steel wire. Since the tying of wire or steel wire is done manually, the wire is usually wrapped around a few times in a localized area with few fixing points. The stress is mainly concentrated in a few small areas where the wire is tied. Furthermore, when construction workers reduce the number of wraps or the tying force is insufficient to improve efficiency, the probability of the wire loosening increases. This can lead to the grouting pipes 200 and overflow pipes 300 loosening, shifting, or even falling off during transportation or hoisting when the precast column 100 is subjected to stress.
[0003] Therefore, existing technologies still need to be improved and developed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a precast column grouting pipe overflow pipe fixing device in view of the above-mentioned defects of the prior art, which aims to solve the problem that the precast column grouting pipe and overflow pipe are easily loosened, displaced or even fall off when they are tied with iron wire or steel wire in the prior art.

[0007] A mounting plate for detachable connection to precast columns;
[0008] Two positioning holes are provided on the fixed plate and penetrate through the fixed plate; the two positioning holes are respectively matched with the grouting pipe and the overflow pipe;
[0009] At least one fixing plate is provided for detachable connection with the fixing plate; the fixing plate is provided with two fixing holes, which respectively cooperate with the grouting pipe and the overflow pipe.
[0010] The precast column grouting pipe overflow pipe fixing device, wherein when the fixing plate and the fixing disc are detachably connected, the positioning hole and the fixing hole correspond one-to-one and are interconnected.
[0011] The precast column grouting pipe overflow pipe fixing device further includes:
[0012] A magnetic sheet is disposed on the fixed sheet; the fixed disk is a metal fixed disk and is used to magnetically attract the magnetic sheet.
[0013] The precast column grouting pipe overflow pipe fixing device includes a magnetic plate located between two fixing holes. The diameter of the magnetic plate is larger than the diameter of the fixing hole and smaller than the width of the fixing plate.
[0014] The precast column grouting pipe overflow pipe fixing device, wherein the positioning hole is an elongated hole and extends along the length direction of the fixing plate.
[0015] The precast column grouting pipe overflow pipe fixing device further includes:
[0016] Multiple threaded connectors; the threaded connectors mate with the positioning holes and are used to detachably connect to the precast column after passing through the positioning holes.
[0017] The precast column grouting pipe overflow pipe fixing device, wherein the width of the positioning hole is equal to the diameter of the grouting pipe and the overflow pipe.
[0018] The precast column grouting pipe overflow pipe fixing device further includes:
[0019] Multiple rubber retaining plugs; the rubber retaining plugs cooperate with the retaining holes to block the grouting pipe and the overflow pipe.
[0020] Beneficial effects: In this application, the grouting pipe and overflow pipe are double-fixed in a superimposed manner through the cooperation of the fixing plate and the fixing piece. This eliminates the need for manual binding with iron or steel wire. The entire process only requires assembling the fixing plate on the precast column, assembling the grouting pipe and overflow pipe into the positioning hole and the fixing hole respectively, and then assembling and fixing the fixing piece. The grouting pipe and overflow pipe are directly inserted into the fixing hole and the positioning hole, and the fixing hole and positioning hole respectively provide double restraint for the grouting pipe and overflow pipe, which is tighter than binding, unaffected by vibration, and reduces the risk of loosening, displacement, or even detachment of the grouting pipe and overflow pipe after the precast column is subjected to stress during transportation or hoisting.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.
[0029] The inventors discovered through research that in traditional processes, grouting pipes and overflow pipes are often tied to the stirrups of precast columns or to the vertical main reinforcement bars inside the precast columns using iron or steel wire. Since the tying of iron or steel wire is done manually, the wire is usually wrapped around a few times in a localized area, with few fixing points. The stress is concentrated in these small areas, and when workers reduce the number of wraps to increase efficiency, the probability of the wire loosening increases. This leads to the grouting pipes and overflow pipes loosening, shifting, or even falling off during transportation or hoisting when the precast column is under stress. Furthermore, the varying tightness of the tying by different workers results in inconsistent fixing quality.
[0030] To solve the above-mentioned technical problems, this application provides a fixing device for the overflow pipe of the grouting pipe of a precast column, such as... Figure 2 , Figure 3 and Figure 4 As shown, the precast column grouting pipe overflow pipe fixing device includes: a fixing plate 1, two positioning holes 2 and at least one fixing plate 3; the fixing plate 1 is used for detachable connection with the precast column 100; the two positioning holes 2 are both provided on the fixing plate 1 and penetrate through the fixing plate 1; the two positioning holes 2 respectively cooperate with the grouting pipe 200 and the overflow pipe 300; the fixing plate 3 is used for detachable connection with the fixing plate 1; the fixing plate 3 is provided with two fixing holes 4, which respectively cooperate with the grouting pipe 200 and the overflow pipe 300.
[0031] Specifically, the grouting pipe 200 and overflow pipe 300 pre-reserved on the precast column 100 will each have at least a portion extending outside the precast column 100. The fixing plate 1 is detachably connected and assembled on the precast column 100 at the positions corresponding to the grouting pipe 200 and overflow pipe 300. At the same time, the grouting pipe 200 and overflow pipe 300 are respectively inserted into the corresponding positioning holes 2, thereby initially positioning the grouting pipe 200 and overflow pipe 300. Then, after the grouting pipe 200 and overflow pipe 300 in the positioning holes 2 are inserted into the corresponding fixing holes 4, the fixing plate 3 is detachably assembled on the fixing plate 1, thereby realizing the fixing of the grouting pipe 200 and overflow pipe 300 by the precast column grouting pipe overflow pipe fixing device.
[0032] In this application, the grouting pipe 200 and the overflow pipe 300 are double-fixed by the cooperation of the fixing plate 1 and the fixing piece 3, eliminating the need for manual binding with iron or steel wire. The entire process only requires assembling the fixing plate 1 on the precast column 100, assembling the grouting pipe 200 and the overflow pipe 300 into the positioning hole 2 and the fixing hole 4 respectively, and then assembling and fixing the fixing piece 3. The grouting pipe 200 and the overflow pipe 300 are directly inserted into the fixing hole 4 and the positioning hole 2. The fixing hole 4 and the positioning hole 2 respectively provide double restraint for the grouting pipe 200 and the overflow pipe 300, which is tighter than binding, unaffected by vibration, and reduces the risk of the grouting pipe 200 and the overflow pipe 300 loosening, shifting, or even falling off when the precast column 100 is subjected to force during transportation or hoisting.
[0033] Furthermore, both the fixing holes 4 and the positioning holes 2 are machined, and all fixing holes 4 have the same specifications, as do the two positioning holes 2, thus avoiding the inconsistent binding quality found in the prior art. Additionally, the fixing plate 3 and the fixing plate 1 are detachably assembled, as are the fixing plate 1 and the precast column 100. When it is necessary to disassemble the precast column grouting pipe overflow pipe fixing device, the fixing plate 1 can be directly removed, allowing the entire precast column grouting pipe overflow pipe fixing device to detach from the precast column 100 and be used on the next precast column 100, improving versatility and reducing costs.
[0034] In this application, when the fixing plate 3 is detachably connected to the fixing disk 1, the positioning hole 2 corresponds one-to-one with the fixing hole 4 and is interconnected.
[0035] Specifically, when the fixing plate 3 is detachably connected to the fixing plate 1, the positioning hole 2 and the fixing hole 4 are correspondingly connected and coaxially arranged. After the grouting pipe 200 and the overflow pipe 300 pass through the positioning hole 2 and the fixing hole 4 respectively, the positioning hole 2 limits and fixes the grouting pipe 200 and the overflow pipe 300 from the inside of the fixing plate 3, and the fixing hole 4 limits and fixes the grouting pipe 200 and the overflow pipe 300 from the outside of the fixing plate 1. This achieves double limiting and fixing of the grouting pipe 200 and the overflow pipe 300, improves the fixing quality, and reduces the risk of loosening and falling off.
[0036] In one embodiment of this application, the width of the positioning hole 2 is equal to the diameter of the grouting pipe 200 and the overflow pipe 300, and the diameter of the fixing hole 4 is equal to the diameter of the grouting pipe 200 and the overflow pipe 300. This allows the grouting pipe 200 and the overflow pipe 300 to be deformed by compression when they are inserted and fixed, thereby forcing them into the positioning hole 2 and the fixing hole 4. The fit between the grouting pipe 200 and the positioning hole 2 and the fixing hole 4 is an interference fit, and the fit between the overflow pipe 300 and the positioning hole 2 and the fixing hole 4 is also an interference fit, thereby reducing the probability of the grouting pipe 200 and the overflow pipe 300 becoming loose from the positioning hole 2 or the fixing hole 4.
[0037] In one embodiment of this application, there are two positioning holes 2, which are elongated holes and extend along the length of the fixed plate 1.
[0038] Specifically, during construction, the actual installation positions of the grouting pipe 200 and the overflow pipe 300 may deviate (e.g., dimensional errors in prefabricated components, pipe installation deviations, etc.). If the positioning hole 2 is a round hole, its position will be difficult to adjust once fixed, potentially leading to inaccurate pipe positioning and affecting the connection effect. In this application, the positioning hole 2 is designed as an elongated hole, allowing for fine-tuning of the positions of the grouting pipe 200 and the overflow pipe 300 within a certain range. This ensures precise pipe alignment, reduces errors, improves the tolerance for construction errors, and prevents incorrect pipe installation due to small dimensional errors.
[0039] The two positioning holes 2 are arranged in parallel and symmetrically. The distance between the two positioning holes 2 is adapted to the distance between the grouting pipe 200 and the overflow pipe 300. Then the grouting pipe 200 can pass through one of the positioning holes 2 and the overflow pipe 300 can pass through the other positioning hole 2, so that the fixing plate 1 can be detachably assembled on the precast column 100.
[0040] like Figure 3 and Figure 5 As shown, the precast column grouting pipe overflow pipe fixing device also includes a magnetic sheet 5, which is disposed on the fixing plate 3; the fixing disk 1 is a metal fixing disk and is used to magnetically attract the magnetic sheet 5.
[0041] Specifically, there are multiple magnetic plates 5, and each magnetic plate 5 corresponds one-to-one with a fixing plate 3. Each fixing plate 3 is used to simultaneously insert and position a grouting pipe 200 and an overflow pipe 300. The fixing plate 3 is provided with the magnetic plate 5, and the fixing plate 3 is detachably assembled on the fixing plate 1 by magnetic attraction between the magnetic plate 5 and the metal fixing plate 1.
[0042] In this application, after the grouting pipe 200 and the overflow pipe 300 pass through their respective positioning holes 2, the grouting pipe 200 is passed through the corresponding fixing hole 4 on the fixing plate 3, and the overflow pipe 300 is passed through another fixing hole 4 on the fixing plate 3. Then, the fixing plate 3 is brought close to the fixing disk 1, and the fixing plate 3 and the fixing disk 1 are attracted to each other, thus positioning the fixing plate 3 on the fixing disk 1. The magnetic attraction assembly method reduces the assembly steps of the fixing plate 3 and improves the assembly efficiency; and when the fixing plate 3 is misaligned on the fixing disk 1, it is not necessary to disassemble the fixing plate 3, but only to apply force to the fixing plate 3 to push it to move, saving time and effort.
[0043] In this application, the fixing plate 3 can be pre-attached to the fixing plate 1 before the grouting pipe 200 and the overflow pipe 300 are sequentially passed through the corresponding positioning hole 2 and fixing hole 4 to limit the positioning of the grouting pipe 200 and the overflow pipe 300. When this assembly method is adopted, since the positioning hole 2 is an elongated hole and the fixing plate 3 is positioned on the fixing plate 1 by magnetic attraction and detachable positioning, the worker can slide and adjust the fixing plate 3 within a certain range to align the grouting pipe 200 and the overflow pipe 300 before inserting and positioning the grouting pipe 200 and the overflow pipe 300, avoiding rework, speeding up installation, reducing construction errors, and improving construction efficiency.
[0044] The two fixing holes 4 are symmetrically arranged along the length of the fixing plate 3. The magnetic plate 5 is located between the two fixing holes 4, and the distance between the magnetic plate 5 and the two fixing holes 4 is equal. This prevents the magnetic attraction of the magnetic plate 5 from being biased to one side due to its proximity to a certain fixing hole 4, thereby preventing the fixing plate 3 from tilting and ensuring the fixing effect of the fixing plate 3 on the fixing plate 1. The magnetic plate 5 is located in the middle position between the two fixing holes 4, so that the magnetic force is evenly distributed. The fixing plate 3 can be tightly attached to the fixing plate 1, preventing the fixing plate 3 from tilting or lifting. This ensures that the positions of the grouting pipe 200 and the overflow pipe 300 will not shift, thereby ensuring the stability of the fixing of the grouting pipe 200 and the overflow pipe 300.
[0045] The magnetic sheet 5 is mounted on the fixing plate 3, and the size of the magnetic sheet 5 plays a crucial role in fixing the fixing plate 3 on the fixing disk 1. If the magnetic sheet 5 is too small, the magnetic attraction is insufficient, and it cannot firmly fix the grouting pipe 200 and the overflow pipe 300, which may cause the fixing plate 3 to loosen or shift. If the magnetic sheet 5 is too large, it may affect the layout of the fixing hole 4, causing the fixing plate 3 to deform and affecting the alignment accuracy of the grouting pipe 200 and the overflow pipe 300. In one embodiment of this application, the diameter of the magnetic sheet 5 is larger than the diameter of the fixing hole 4 and smaller than the width of the fixing plate 3, ensuring that the magnetic sheet 5 just covers the main stress area of the fixing plate 3, enhancing the fixing effect, and ensuring that the fixing plate 3 will not tilt or warp when under force, thus improving stability.
[0046] The precast column grouting pipe overflow pipe fixing device also includes multiple threaded connectors 6; the threaded connectors 6 cooperate with the positioning holes 2 and are used to pass through the positioning holes 2 and be detachably connected to the precast column 100.
[0047] Specifically, there are four threaded connectors 6. These four threaded connectors 6 pass through the positioning holes 2 from the four corners near the fixing plate 1 and are detachably connected to the precast column 100, thereby enabling the detachable assembly of the fixing plate 1 onto the precast column 100. It can be seen that in this application, when fixing the grouting pipe 200 and overflow pipe 300 using the precast column grouting pipe overflow pipe fixing device, only the four threaded connectors 6 need to be installed, and then the insertion of the grouting pipe 200 and overflow pipe 300 into the positioning holes 2 and the fixing holes 4 is performed. Compared to the prior art's wire or steel wire binding operation for each grouting pipe 200 and overflow pipe 300, this application reduces the operation steps, improves the fixing effect, and enhances the fixing quality.
[0048] like Figure 4 As shown, the precast column grouting pipe overflow pipe fixing device also includes multiple rubber fixing plugs 7; the rubber fixing plugs 7 cooperate with the fixing holes 4 to block the grouting pipe 200 and the overflow pipe 300; the rubber fixing plugs 7 are wedge-shaped rubber plugs.
[0049] In summary, this application provides a fixing device for the grouting pipe overflow pipe of a precast column, comprising: a fixing plate for detachable connection with the precast column; two positioning holes disposed on the fixing plate and penetrating the fixing plate; the two positioning holes respectively cooperating with the grouting pipe and the overflow pipe; at least one fixing plate for detachable connection with the fixing plate; the fixing plate is provided with two fixing holes, which respectively cooperate with the grouting pipe and the overflow pipe. In this application, the grouting pipe and the overflow pipe are double-fixed in a superimposed manner through the cooperation of the fixing plate and the fixing plate, eliminating the need for manual binding with iron or steel wire. The entire process only requires assembling the fixing plate on the precast column, assembling the grouting pipe and the overflow pipe into the positioning holes and the fixing holes respectively, and then assembling and fixing the fixing plate. The grouting pipe and the overflow pipe are directly inserted into the fixing hole and the positioning hole, respectively. The fixing hole and the positioning hole provide double restraint for the grouting pipe and the overflow pipe, which is tighter than binding and is not affected by vibration. This reduces the risk of the grouting pipe and the overflow pipe loosening, shifting or even falling off after the precast column is subjected to force during transportation or hoisting.
