Description

Technical Field

[0001] This utility model relates to the field of bridge engineering construction formwork technology, and in particular to a transverse prestressed reserved hole forming device. Background Technology

[0002] In many engineering fields such as construction and bridges, it is often necessary to pre-embed steel pipes in concrete structures to form specific channels. These channels may be used to install cables, pipes and other facilities, playing a key role in the normal operation and functionality of the engineering structure.

[0003] In existing construction methods, steel pipes are easily disturbed by concrete flow and vibrators during concrete pouring due to the lack of effective fixing measures. This disturbance not only affects the forming quality of the ducts but may also cause the steel pipes to come out, leading to the pre-embedded parts being blocked by concrete, thus affecting the function and safety of the structure.

[0004] Furthermore, in existing technologies, the holes on the panel are designed to be slightly larger than the steel pipes to facilitate their insertion. While this design facilitates pipe installation, it also introduces grout leakage, affecting the quality of concrete pouring. Foam adhesive is typically used for sealing, but this adhesive easily seeps into the concrete, impacting the beam's overall shape. Utility Model Content

[0005] This utility model provides a transverse prestressed reserved hole forming device to solve the defects of the prior art in that the steel pipe cannot be effectively fixed and the sealing between it and the panel is poor during the concrete pouring process. It effectively prevents the steel pipe from moving or falling out, ensures good hole forming, and avoids the embedded parts being blocked by concrete. At the same time, it achieves the overall sealing of the template and the steel pipe, eliminates grout leakage, eliminates the need for foam glue sealing, and significantly improves the appearance quality of the beam.

[0007] The mold body has a first template and a second template arranged at intervals along a first direction, the first template and the second template are spaced apart to form a casting space, and the first template has a through hole communicating with the casting space.

[0008] A perforated steel pipe having a head end that passes through the through hole into the casting space and a tail end located outside the casting space;

[0009] An embedded mechanism is provided within the casting space and on the inner wall of the second template corresponding to the through hole. The embedded mechanism is positioned in contact with the end of the first end, or the end of the first end passes through the embedded mechanism.

[0010] Ear plate mechanism, wherein the ear plate mechanism is disposed on the outer peripheral wall of the perforated steel pipe near the tail end;

[0011] A clamping mechanism is provided along the periphery of the through hole on the side of the first template away from the casting space. The clamping mechanism is used to press the ear plate mechanism toward the pre-embedded mechanism to clamp the holed steel pipe and seal the through hole.

[0012] According to the present invention, the diameter of the formed hole steel pipe gradually increases from the first end to the last end, and the diameter of the formed hole steel pipe corresponding to the ear plate mechanism is greater than the diameter of the through hole.

[0013] According to the present invention, a transverse prestressed reserved hole forming device is provided, wherein the ear plate mechanism includes at least two abutting protrusions, the two abutting protrusions are arranged to protrude radially along the hole-forming steel pipe, and the abutting protrusions are movably abutting and cooperating with the pressing mechanism to press the hole-forming steel pipe.

[0014] According to the present invention, a transverse prestressed reserved hole forming device is provided, wherein the ear plate mechanism includes at least two abutting protrusions and at least two sealing parts. The abutting protrusions and the sealing parts are staggered along the outer circumference of the formed steel pipe. The abutting protrusions are movably abutting with the pressing mechanism, and the sealing parts are used to seal the gap between the formed steel pipe and the through hole.

[0015] According to the present invention, a transverse prestressed reserved hole forming device is provided, wherein a plurality of the abutting protrusions are symmetrically arranged about the center of the axis of the formed hole steel pipe.

[0016] According to the present invention, a transverse prestressed reserved hole forming device is provided, wherein the clamping mechanism includes a clamping connecting seat and a clamping adjusting component. The clamping connecting seat is connected between the clamping adjusting component and the first template. The clamping adjusting component is used to clamp the ear plate mechanism along a first direction and toward the pre-embedded mechanism.

[0017] According to the present invention, a transverse prestressed reserved hole forming device is provided, wherein the clamping adjustment component includes a screw and a nut, the nut is fixed on the clamping connecting seat, the screw and the nut are threadedly engaged, and one end of the screw near the pre-embedded mechanism is abutted against the ear plate mechanism.

[0018] According to the present invention, a transverse prestressed reserved hole forming device is provided at the end of the first end, wherein a tapered pin extending in a first direction is provided at the end of the first end, and the pre-embedded mechanism includes an anchor, which is inserted into the tapered pin to position and fix the first end of the formed steel pipe.

[0019] According to the present invention, a transverse prestressed reserved hole forming device is provided, wherein the anchor is recessed on the side facing the casting space to form an anchor cavity, and an anchor plate is provided on the side of the anchor facing the first template, and the tapered pin passes through the anchor plate and is inserted into the anchor cavity.

[0020] According to the present invention, a transverse prestressed reserved hole forming device is provided, wherein the number of the pressing mechanism is the same as the number of the abutting protrusion, and they are arranged in a one-to-one correspondence.

[0021] The transverse prestressed reserved hole forming device provided by this utility model has a clamping mechanism positioned along the periphery of the through hole on the side of the first template away from the pouring space. Its function is to press the ear plate mechanism towards the pre-embedded mechanism. When the clamping mechanism applies pressure to the ear plate mechanism, the perforated steel pipe is tightly pressed against the pre-embedded mechanism under the action of the ear plate mechanism, thus keeping the perforated steel pipe in a relatively fixed position within the pouring space. During concrete pouring, the concrete is fluid and the vibrator vibrates, but the continuous pressure provided by the clamping mechanism can resist the influence of these external forces on the perforated steel pipe, effectively preventing the perforated steel pipe from shifting or coming out. Simultaneously, the interaction between the pre-embedded mechanism and the first end ensures that the perforated steel pipe always remains in the correct position, thereby guaranteeing the forming quality of the hole. Furthermore, when the clamping mechanism presses the ear plate mechanism towards the pre-embedded mechanism, it not only clamps the perforated steel pipe but also ensures that the steel pipe (or the ear plate along with it) makes tight contact with the edge of the through hole on the first template by pressing the ear plate mechanism. This prevents concrete slurry from seeping out of the gap, thus achieving an overall seal between the template and the steel pipe. This sealing method relies on mechanical pressure, ensuring a reliable seal and effectively preventing concrete slurry from leaking out of the gap between the through hole and the perforated steel pipe. It eliminates the need for foam sealant and significantly improves the appearance quality of the beam. Attached Figure Description

[0037] The following is combined Figures 1 to 5 The present invention will provide a detailed description of a transverse prestressed reserved hole forming device through specific embodiments and application scenarios.

[0038] In the embodiments of this utility model, such as Figures 1 to 3As shown, a transverse prestressed pre-reserved hole forming device 10 includes a mold body 100, a hole-forming steel pipe 200, a pre-embedding mechanism 300, an ear plate mechanism 400, and a clamping mechanism 500. The mold body 100 has a first template 110 and a second template 120 arranged at intervals along a first direction. The first template 110 and the second template 120 form a casting space 130 at intervals. The first template 110 has a through hole 111 communicating with the casting space 130. The hole-forming steel pipe 200 has a head end 210 passing through the through hole 111 into the casting space 130 and a tail end 220 located outside the casting space 130. Mechanism 300 is located within the casting space 130 and on the inner wall of the second template 120 corresponding to the through hole 111. The pre-embedded mechanism 300 is positioned in contact with the end of the first end 210, or the end of the first end 210 is inserted through the pre-embedded mechanism. Ear plate mechanism 400 is located on the outer peripheral wall of the drilled steel pipe 200 near the tail end 220. Pressing mechanism 500 is located along the periphery of the through hole 111 on the side of the first template 110 away from the casting space 130. Pressing mechanism 500 is used to press ear plate mechanism 400 toward pre-embedded mechanism 300 to press drilled steel pipe 200 and seal through hole 111.

[0039] The mold body 100 has a first template 110 and a second template 120 arranged at intervals along a first direction, forming a pouring space 130 between them. The mold body 100 provides a specific space for concrete pouring, ensuring that the concrete can be molded according to design requirements during the pouring process to form the required concrete structure. At the same time, the interval arrangement of the first template 110 and the second template 120 provides a basic framework for the subsequent installation of components such as the perforated steel pipe 200, enabling the entire device to be rationally laid out and realize the forming function of prestressed reserved holes.

[0040] The perforated steel pipe 200 has a head end 210 and a tail end 220 arranged opposite to each other. The head end 210 passes through a through hole 111 into the pouring space 130, while the tail end 220 is located outside the pouring space 130. After the concrete is poured, a transverse prestressing reserved hole will be formed at the location of the perforated steel pipe 200 for subsequent installation of prestressing tendons and other facilities to meet the prestressing requirements of the engineering structure. The head end 210 entering the pouring space 130 and the tail end 220 being located on the outside facilitate cooperation with external clamping mechanisms 500 and other components to achieve the fixation and sealing of the steel pipe.

[0041] The embedded mechanism 300 is located within the pouring space 130 and on the inner wall corresponding to the through hole 111 of the second template 120. The embedded mechanism 300 is positioned by abutting against the end of the first end 210, or the end of the first end 210 passes through the embedded mechanism 300. The embedded mechanism 300 abuts against the end of the first end 210 of the drilled steel pipe 200, or the end of the first end 210 passes through the embedded mechanism 300, providing accurate positioning for the drilled steel pipe 200 within the pouring space 130. This ensures that the position of the drilled steel pipe 200 meets design requirements, thereby guaranteeing the accurate positioning of the subsequently formed prestressed reserved holes and facilitating the correct insertion of prestressing tendons. During concrete pouring, it provides support for the drilled steel pipe 200, preventing displacement or deformation under the action of concrete flow and vibrating rods, further ensuring the forming quality of the duct.

[0042] The ear plate mechanism 400 is located on the outer peripheral wall of the perforated steel pipe 200 near the tail end 220. The ear plate mechanism 400 acts as the target of the clamping mechanism 500, providing a point of force application. When the clamping mechanism 500 applies pressure to the ear plate mechanism 400, the pressure is transmitted to the perforated steel pipe 200, thus clamping and fixing the perforated steel pipe 200.

[0043] A clamping mechanism 500 is located along the periphery of the through hole 111 on the side of the first template 110 facing away from the pouring space 130. The clamping mechanism 500 is used to press the ear plate mechanism 400 towards the pre-embedded mechanism 300 to clamp the perforated steel pipe 200 and seal the through hole 111. By pressing the ear plate mechanism 400 towards the pre-embedded mechanism 300, the perforated steel pipe 200 is tightly fixed in the pouring space 130, preventing the perforated steel pipe 200 from shifting or falling out due to the flow of concrete and the vibration of the vibrator during concrete pouring, thus ensuring the forming quality of the duct. During the pressing of the ear plate mechanism 400, the perforated steel pipe 200 (or together with the ear plate) is brought into close contact with the edge of the through hole 111 on the first template 110, thereby sealing the through hole 111 and preventing concrete grout from leaking out from the gap between the through hole 111 and the perforated steel pipe 200. This ensures the quality of concrete pouring and avoids affecting the appearance and structural performance of the beam due to grout leakage.

[0044] This application involves placing a clamping mechanism 500 along the periphery of the through hole 111 on the side of the first template 110 facing away from the pouring space 130. Its function is to press the ear plate mechanism 400 towards the embedded mechanism 300. When the clamping mechanism 500 applies pressure to the ear plate mechanism 400, the perforated steel pipe 200 is tightly pressed against the embedded mechanism 300 under the action of the ear plate mechanism 400, thus keeping the perforated steel pipe 200 in a relatively fixed position within the pouring space 130. During concrete pouring, the concrete is fluid and the vibrator vibrates, but the continuous pressure provided by the clamping mechanism 500 can resist the influence of these external forces on the perforated steel pipe 200, effectively preventing the perforated steel pipe 200 from shifting or coming out. Simultaneously, the interaction between the embedded mechanism 300 and the end of the first end 210 ensures that the perforated steel pipe 200 remains in the correct position, thereby guaranteeing the forming quality of the duct. Furthermore, when the clamping mechanism 500 presses the ear plate mechanism 400 towards the pre-embedded mechanism 300, it not only clamps the perforated steel pipe 200, but also ensures that the steel pipe (or the ear plate on it) is in close contact with the edge of the through hole 111 on the first template 110 by pressing the ear plate mechanism 400, thus preventing concrete grout from seeping out of the gap, thereby achieving an overall seal between the template and the steel pipe. This sealing method relies on mechanical pressure, ensuring a reliable sealing effect and effectively preventing concrete grout from leaking out of the gap between the through hole 111 and the perforated steel pipe 200. It eliminates the need for foam sealant and significantly improves the appearance quality of the beam.

[0045] Reference Figure 4 According to the present invention, a transverse prestressed reserved hole forming device 10 is provided, wherein the diameter of the hole forming steel pipe 200 gradually increases from the first end 210 to the tail end 220, and the diameter of the hole forming steel pipe 200 corresponding to the ear plate mechanism 400 is greater than the diameter of the through hole 111.

[0046] Understandably, the clamping mechanism 500 clamps the perforated steel pipe 200 and seals the through hole 111 by pressing the ear plate mechanism 400. Since the diameter of the perforated steel pipe 200 corresponding to the ear plate mechanism 400 is larger than the diameter of the through hole 111, when the clamping mechanism 500 applies pressure to the ear plate mechanism 400, the perforated steel pipe 200 will be tightly squeezed against the edge of the through hole 111 at that location. This squeezing action effectively prevents concrete slurry from leaking out from the gap between the through hole 111 and the perforated steel pipe 200, achieving a good sealing effect.

[0047] Reference Figure 1 and Figure 3According to the present invention, a transverse prestressed reserved hole forming device 10 is provided, wherein the ear plate mechanism 400 includes at least two abutting protrusions 410, the two abutting protrusions 410 are arranged to protrude radially along the hole forming steel pipe 200, and the abutting protrusions 410 are movably abutting and cooperating with the pressing mechanism 500 to press the hole forming steel pipe 200.

[0048] Understandably, multiple abutting protrusions 410 can distribute pressure to different positions of the perforated steel pipe 200, so that the perforated steel pipe 200 is subjected to a more balanced clamping force in all directions, thereby ensuring its positional stability within the casting space 130 and avoiding affecting the forming quality of the prestressed reserved hole due to uneven force.

[0049] The radially protruding abutment 410 increases the contact area with the clamping mechanism 500. A larger contact area improves the transmission efficiency of the clamping force, allowing the pressure applied by the clamping mechanism 500 to act more fully on the perforated steel pipe 200. Simultaneously, the increased contact area helps to disperse stress, reducing damage to the perforated steel pipe 200 or the abutment 410 itself caused by excessive local pressure, thus extending the service life of the device.

[0050] The movable contact fit allows for a certain degree of relative movement between the contact protrusion 410 and the clamping mechanism 500. During construction, the pressure of the clamping mechanism 500 can be adjusted according to the actual situation to adapt to different construction stages and requirements.

[0051] Reference Figure 5 According to the present invention, a transverse prestressed reserved hole forming device 10 is provided. The ear plate mechanism 400 includes at least two abutting protrusions 410 and at least two sealing parts 420. The abutting protrusions 410 and the sealing parts 420 are staggered along the outer circumference of the hole-forming steel pipe 200. The abutting protrusions 410 are in movable abutting cooperation with the pressing mechanism 500. The sealing parts 420 are used to seal the gap between the hole-forming steel pipe 200 and the through hole 111.

[0052] Understandably, the abutting protrusion 410 and the clamping mechanism 500 engage movably, allowing the clamping mechanism 500 to effectively transmit pressure to the perforated steel pipe 200. With at least two abutting protrusions 410, the clamping force can be more evenly distributed on the outer circumference of the perforated steel pipe 200, preventing the perforated steel pipe 200 from shifting or deforming due to uneven force. During concrete pouring, the flow of concrete and the vibration of the vibrator exert external forces on the perforated steel pipe 200. The cooperation between the abutting protrusion 410 and the clamping mechanism 500 resists these external forces, ensuring that the perforated steel pipe 200 remains in a stable position, thereby guaranteeing the forming quality of the prestressed reserved hole.

[0053] The movable contact mechanism allows for a certain degree of relative movement between the contact protrusion 410 and the clamping mechanism 500, which facilitates the adjustment of the clamping force. During construction, the pressure of the clamping mechanism 500 can be adjusted in a timely manner according to factors such as the concrete pouring conditions and vibration intensity to meet the needs of different construction stages.

[0054] During concrete pouring, the sealing part 420 effectively prevents concrete slurry from leaking out from the gap between the perforated steel pipe 200 and the through hole 111. In this embodiment, the sealing part 420 is directly mounted on the ear plate mechanism 400, forming an integral part with the perforated steel pipe 200, eliminating the need for additional sealing materials and complex sealing processes. This not only simplifies the construction process and improves construction efficiency but also reduces construction costs.

[0055] The abutting protrusion 410 and the sealing part 420 are arranged alternately, enabling the ear plate mechanism 400 to simultaneously perform both pressing and sealing functions. Under the action of the pressing mechanism 500, the abutting protrusion 410 presses and fixes the perforated steel pipe 200, while the sealing part 420 seals the gap. The two work together to ensure the stability and sealing of the perforated steel pipe 200 during the casting process.

[0056] Reference Figure 3 and Figure 5 According to the present invention, a transverse prestressed reserved hole forming device 10 is provided, wherein a plurality of abutting protrusions 410 are symmetrically arranged about the center of the axis of the hole forming steel pipe 200.

[0057] It is understood that when the multiple abutting protrusions 410 are symmetrically arranged about the centerline of the holed steel pipe 200 in this embodiment, the pressure applied by the clamping mechanism 500 can be evenly distributed on the outer circumference of the holed steel pipe 200. During the forming process of the transverse prestressed reserved hole, the holed steel pipe 200 needs to maintain a stable position to ensure the forming accuracy of the reserved hole. The evenly distributed clamping force can prevent the holed steel pipe 200 from shifting or tilting due to uneven force, ensuring that the holed steel pipe 200 is always in the correct position, providing a reliable guarantee for the subsequent installation and use of prestressing tendons.

[0058] Reference Figures 1 to 3 According to the present invention, a transverse prestressed reserved hole forming device 10 is provided, wherein the pressing mechanism 500 includes a pressing connecting seat 510 and a pressing adjusting component 520. The pressing connecting seat 510 is connected between the pressing adjusting component 520 and the first template 110. The pressing adjusting component 520 is used to press the ear plate mechanism 400 along the first direction and toward the pre-embedded mechanism 300.

[0059] Understandably, the clamping connector 510 connects the clamping adjustment assembly 520 and the first template 110, acting as a connecting bridge. The clamping connector 510 securely fixes the clamping adjustment assembly 520 to the first template 110, ensuring that the entire clamping mechanism 500 and the first template 110 form a stable whole. When the clamping adjustment assembly 520 applies clamping force, the clamping connector 510 accurately transmits this force to the ear plate mechanism 400. As a force transmission medium, it ensures the effective transmission of clamping force, allowing the ear plate mechanism 400 to receive sufficient pressure, thereby achieving the clamping and fixing of the perforated steel pipe 200.

[0060] The clamping adjustment assembly 520 is a component used to perform the clamping operation. The clamping adjustment assembly 520 applies pressure along a first direction (typically perpendicular to the template plane) to clamp the ear plate mechanism 400 toward the embedded mechanism 300. This ensures that the perforated steel pipe 200 remains fixed during casting, preventing movement or detachment, and also clamps and seals the outer edge of the ear plate mechanism 400 or the perforated steel pipe 200 to block the through hole 111, achieving a sealing effect.

[0061] The clamping adjustment component 520 is designed to allow for adjustment of the clamping force. This means that the clamping force can be adjusted according to different construction conditions and requirements to ensure the fixing effect of the perforated steel pipe 200, and also improves the adaptability and flexibility of the device.

[0062] Reference Figures 1 to 3 According to the present invention, a transverse prestressed reserved hole forming device 10 is provided, and the clamping adjustment component 520 includes a screw 521 and a nut 522. The nut 522 is fixed on the clamping connecting seat 510. The screw 521 and the nut 522 are threadedly engaged. The end of the screw 521 near the pre-embedded mechanism 300 is abutted against the ear plate mechanism 400.

[0063] Understandably, the screw 521 and nut 522 are threaded together, allowing the screw 521 to rotate relative to the nut 522. When the screw 521 is rotated, it moves along the axis of the thread, thereby changing the distance between it and the ear plate mechanism 400. In this way, construction personnel can flexibly adjust the clamping force of the screw 521 on the ear plate mechanism 400 according to actual construction needs.

[0064] The threaded fit offers high precision, allowing for accurate control of the screw 521's movement distance and, consequently, the clamping stroke. During the transverse prestressed pre-drilled hole forming process, strict requirements are placed on the installation position and clamping degree of the drilled steel pipe 200. Precise clamping stroke control ensures that the drilled steel pipe 200 is accurately fixed in the predetermined position, guaranteeing the forming accuracy of the prestressed pre-drilled hole. By precisely adjusting the screw 521's inward or outward rotation, construction personnel can accurately apply clamping force to the ear plate mechanism 400, avoiding quality problems caused by over- or under-clamping.

[0065] Reference Figure 2 and Figure 6 According to the present invention, a transverse prestressed reserved hole forming device 10 is provided, wherein a tapered pin 211 extending in a first direction is provided on the end of the first end 210, and the pre-embedded mechanism 300 includes an anchor 310, which is inserted into the tapered pin 211 to position and fix the first end 210 of the hole-forming steel pipe 200.

[0066] It is understandable that the tapered pin 211 extends along the first direction, providing a clear guide for the connection between the head end 210 of the holed steel pipe 200 and the anchor 310 in the pre-embedded mechanism 300. At the same time, the forming steel pipe 200 may collide with the reinforcing bars in the pouring space 130 during the process of inserting into the mold body 100. The tapered pin 211 plays a certain role in avoiding collisions and facilitates the installation of the forming steel pipe 200.

[0067] In some embodiments, the anchor 310 has a recessed anchor cavity 312 on the side facing the casting space, and an anchor plate 311 is provided on the side of the anchor 310 facing the first template. The tapered pin 211 passes through the anchor plate 311 and is inserted into the anchor cavity 312.

[0068] The insertion of the anchor 310 and the tapered pin 211 allows the first end 210 of the drilled steel pipe 200 to be quickly positioned with the pre-embedded mechanism 300. When the tapered pin 211 is inserted into the anchor 310, the fit between the two quickly determines the position of the first end 210 of the drilled steel pipe 200, avoiding complex positioning operations. During installation, construction personnel can quickly and accurately connect the first end 210 of the drilled steel pipe 200 to the anchor 310 according to the extension direction of the tapered pin 211, reducing the time spent on trial and error and improving construction efficiency.

[0069] Reference Figure 1 and Figure 3 According to the present invention, a transverse prestressed reserved hole forming device 10 is provided, wherein the number of pressing mechanisms 500 is the same as the number of abutting protrusions 410, and they are arranged in a one-to-one correspondence.

[0070] Understandably, the one-to-one correspondence arrangement creates a stable mechanical system between the clamping mechanism 500 and the abutment protrusion 410. Each clamping mechanism 500 can effectively constrain the corresponding abutment protrusion 410, thereby fixing the perforated steel pipe 200 and ensuring the stability of the entire device during construction processes such as concrete pouring and vibration.

[0071] The method of using the transverse prestressed reserved hole forming device 10 provided in this embodiment is as follows:

[0072] The perforated steel pipe 200 is placed parallel to the reserved channel, and the ear plate mechanism 400 and the clamping mechanism 500 are staggered. This parallel placement ensures that the steel pipe can smoothly enter the predetermined position when inserted into the through hole 111. The staggered arrangement between the ear plate mechanism 400 and the clamping mechanism 500 allows for alignment between them in subsequent steps by rotating the steel pipe. This design facilitates operation and avoids complex alignment issues during initial installation.

[0073] The first end 210 of the drilled steel pipe 200 is inserted into the through hole 111 and abuts against the pre-embedded mechanism 300 to position the first end 210 of the drilled steel pipe 200. It can be understood that by inserting the first end 210 of the drilled steel pipe 200 into the through hole 111 and abutting against the pre-embedded mechanism 300, the accurate position of the first end 210 of the steel pipe within the casting space 130 is ensured. The abutting relationship between the pre-embedded mechanism 300 (such as an anchor 310) and the first end 210 of the drilled steel pipe 200 (such as a tapered pin 211) provides initial fixation, preventing the steel pipe from shifting during subsequent operations.

[0074] Rotate the steel pipe to align the ear plate mechanism 400 with the clamping mechanism 500. Understandably, after the first end 210 is positioned, by rotating the steel pipe, each protrusion on the ear plate mechanism 400 (with the abutting protrusion 410 and the sealing part 420) can be moved to the position directly below or in contact with the corresponding clamping mechanism 500 (the end of the screw 521) to ensure that the clamping force can be accurately applied to the designed contact point.

[0075] Adjusting the clamping mechanism 500 so that it presses the ear plate towards the pre-embedded mechanism 300, thereby clamping and fixing the perforated steel pipe 200. It is understood that by adjusting the clamping mechanism 500 to press the ear plate towards the pre-embedded mechanism 300, a stable fixing effect can be provided for the perforated steel pipe 200. During concrete pouring and vibration, the perforated steel pipe 200 will be subjected to the pressure and impact of concrete. If there is insufficient clamping force, the perforated steel pipe 200 may shift or deform, affecting the forming quality of the prestressed reserved hole. While clamping the ear plate mechanism 400, the sealing part 420 on the ear plate mechanism 400 or the outer edge of the conical perforated steel pipe 200 is also pressed against the through hole 111, thereby filling the gap between the perforated steel pipe and the template through hole 111, achieving a reliable seal and preventing concrete slurry from seeping in.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
