Description

Technical Field

[0001] This utility model relates to the field of bridge anti-ship collision technology, and in particular to a pre-embedded module based on bridge pier anti-ship collision facilities. Background Technology

[0002] With societal development, numerous bridges have been built across waterways to connect surrounding areas. While these bridges have boosted regional economic development, they have also impacted water transport, particularly ship navigation. Due to underwater currents or human error, ships risk veering off course and colliding with bridge piers and abutments. Such collisions can easily damage or even cause bridges to collapse, resulting in severe casualties and economic losses. Therefore, it is necessary to prevent or mitigate the damage caused by ship collisions with bridge piers and abutments.

[0003] To reduce bridge damage and casualties caused by ship collisions, an increasing number of bridges navigable by sea are equipped with anti-ship collision facilities. Among them, fixed anti-ship collision facilities are often connected and fixed to the piers or abutments by pre-embedded bolts, sleeves, or steel clamps. The installation process of pre-embedded bolts and sleeves often requires drilling holes in the formwork of the piers or abutments for positioning. After drilling the holes in the formwork, the water-stopping process is complicated, which reduces construction efficiency and is not conducive to the reuse of the formwork. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a pre-embedded module based on bridge pier anti-ship collision facilities, so as to solve the problem that the installation of pre-embedded bolt components of fixed anti-ship collision facilities in the prior art requires drilling holes in the template of the bridge pier or abutment for positioning, which is not conducive to the turnover and utilization of the template and reduces construction efficiency.

[0005] This utility model provides a pre-embedded module for anti-ship collision facilities on bridge piers, comprising a pre-embedded steel plate that fits snugly against the template of the target bridge pier. The pre-embedded steel plate has mating holes, and pre-embedded nuts are fixedly installed at each mating hole. One end of the pre-embedded nut communicates with the outside through the mating hole for the installation of the anti-ship collision facility. The other end of the pre-embedded nut is sealed by an anchor rod, which is fixed to the pre-embedded steel plate. During construction, the pre-embedded steel plate fits snugly against the template, sealing the mating holes. This allows both ends of the pre-embedded nut to be sealed by the template and the anchor rod, respectively. No holes need to be drilled in the template, facilitating its reuse. Furthermore, the pre-embedded steel plate and anchor rod can be easily connected and positioned to the steel mesh of the construction site, simplifying construction and improving efficiency.

[0007] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0008] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0009] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0010] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0011] To address the issue that the installation of pre-embedded bolt components in existing fixed anti-ship collision facilities requires drilling holes in the formwork of bridge piers or abutments for positioning, which hinders formwork reuse and reduces construction efficiency, this invention provides a pre-embedded module for anti-ship collision facilities on bridge piers. This module includes a pre-embedded steel plate that fits snugly against the formwork of the target bridge pier. The pre-embedded steel plate has mating holes, and pre-embedded nuts are fixedly installed at each hole. One end of the pre-embedded nut communicates with the outside through the mating hole for the installation of the anti-ship collision facility, while the other end is sealed by an anchor rod fixed to the pre-embedded steel plate. During construction, the pre-embedded steel plate fits snugly against the formwork, sealing the mating holes. This allows both ends of the pre-embedded nut to be sealed by the formwork and the anchor rod, eliminating the need for drilling holes in the formwork, facilitating its reuse, and enabling convenient connection and positioning with the reinforcing mesh of the construction site via the pre-embedded steel plate and anchor rod. This simplifies construction and improves efficiency.

[0012] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The pre-embedded module based on the anti-ship collision facility for bridge piers in this embodiment includes a pre-embedded steel plate 10, a pre-embedded bolt assembly 20 and a pre-embedded reinforcing bar 25 on the pre-embedded steel plate 10, the pre-embedded steel plate 10 can fit and match the template of the target bridge pier, the pre-embedded steel plate 10 is provided with a docking hole (not shown in the figure), the pre-embedded bolt assembly 20 is provided at each docking hole, and the pre-embedded nut 21 is provided in the pre-embedded bolt assembly 20 so that the anti-ship collision facility for bridge piers can be screwed and fixed to the pre-embedded nut 21 in the pre-embedded bolt assembly 20 through the docking hole.

[0013] During construction, the pre-embedded modules are used as follows: Figure 1 The template is attached to the formwork and fixed by the internal steel mesh. The mating holes on the embedded steel plate 10 can be sealed by the template. After the concrete is poured and cured, the embedded module can be effectively fixed in the pier or abutment. When the template is removed, the mating holes are naturally exposed, and the internal embedded nuts 21 form screw holes at the mating holes.

[0014] To ensure that the embedded nut 21 is not blocked by internal concrete penetration, in this embodiment, the embedded bolt assembly 20 also includes an anchor rod 22. The anchor rod 22 is fitted inside the embedded nut 21, sealing one end of the embedded nut 21. To ensure the depth of the bolt hole formed by the embedded nut 21 and the sealing effect, the embedding depth of the anchor rod 22 to the embedded nut 21 needs to be determined according to actual needs. For example, if the length of the embedded nut 21 is 11cm, the embedding depth of the anchor rod 22 to the embedded nut 21 is 5cm, and the depth of the bolt hole formed can reach 6cm, which can take into account the sealing effect and the requirements of the anti-ship collision facility for bridge piers for the installation bolt hole.

[0015] To ensure the reliability of the pre-embedded module in the pier or abutment, in this embodiment, the anchor rod 22 is fixedly connected to the pre-embedded steel plate 10, which can further improve the fixing effect of the pre-embedded bolt assembly.

[0016] Specifically, in this embodiment, the anchor rod 22 is fixedly connected to the embedded steel plate 10 via embedded reinforcing bars 25. Both ends of the embedded reinforcing bars 25 are welded to the anchor rod 22 and the embedded steel plate 10. To improve the welding and fixing effect, such as... Figure 2 As shown, the end of the pre-embedded steel bar 25 connected to the pre-embedded steel plate 10 is bent. The bent section can fit the pre-embedded steel plate 10, increasing the welding area and improving the fixing effect. This can reduce the risk of the pre-embedded steel plate 10 detaching, thereby improving the installation and fixing reliability of the bridge pier anti-ship collision facility and improving the protection reliability of the bridge pier.

[0017] To facilitate the welding of the pre-embedded reinforcing bars 25 to the pre-embedded steel plates 10, in such cases... Figure 2In the state shown, the embedded steel bar 25 is not yet associated with the anchor bar 22. After the embedded steel bar 25 is welded to the embedded steel plate 10, the embedded steel bar 25 is bent so that the other end of the embedded steel bar 25 crosses the anchor bar 22 for welding. After the embedded steel bar 25 is connected to the anchor bar 22, a triangular frame structure can be formed to improve the fixing effect.

[0018] To avoid the risk of contaminants penetrating and blocking the interior of the embedded nut 21, making it difficult to effectively install the fixing bolts of the bridge pier anti-ship collision facility, in this embodiment, the embedded module also includes a sealing head (not shown in the figure). The sealing head is detachably connected to the embedded nut 21 through the mating hole on the embedded steel plate 10. Before and during construction, the embedded nut 21 is sealed and protected by the sealing head. The sealing head is then removed when installing the bridge pier anti-ship collision facility. For example, a countersunk bolt can be selected as the sealing head. After installation, its nut can be embedded in the mating hole to keep the outer surface of the embedded steel plate 10 flat, so that the embedded steel plate 10 fits and seals with the template.

[0019] To ensure the effective fixation of the anti-ship collision facilities on bridge piers, multiple installation points are often required, and each installation point needs to be equipped with a set of pre-embedded bolt assemblies. To facilitate the installation of multiple sets of pre-embedded bolt assemblies, in this embodiment, as follows... Figure 1 As shown, the embedded steel plate 10 has a ring structure, and the embedded bolt assemblies are spaced apart along the arrangement path of the embedded steel plate, so that multiple sets of embedded bolt assemblies can be installed uniformly through the same embedded steel plate 10, and it is convenient to mark the installation points through the same embedded steel plate 10. In an optional embodiment, the embedded steel plate 10 can also be set as a cross structure.

[0020] After construction is completed and the formwork is removed, the embedded steel plate 10 is exposed. Its appearance is somewhat different from that of the concrete. It can also be used to indicate the installation position of the anti-ship collision facility, which facilitates the installation and positioning of the anti-ship collision facility.

[0021] To improve the fixing effect of the anchor rod 22 in concrete, in this embodiment, as follows: Figure 3 As shown, a base plate 23 is also fixedly installed on the base rod 22. By limiting the base plate 23 with the concrete, the axial limiting and fixing effect of the base rod 22 can be improved.

[0022] To reduce the impact of damage to the outer concrete of the pier on the fixing effect, in this embodiment, the anchor plate 23 is provided with the anchor rod 22 away from the pre-embedded nut 21 and away from the outer layer of the pier. When the outer concrete of the pier is damaged and detached, the fixing effect of the deep anchor plate 23 can be maintained, thereby ensuring the fixing effect of the anchor rod 22.

[0023] This utility model provides a pre-embedded module for anti-ship collision facilities on bridge piers, comprising a pre-embedded steel plate that fits snugly against the template of the target bridge pier. The pre-embedded steel plate has mating holes, and pre-embedded nuts are fixedly installed at each mating hole. One end of the pre-embedded nut communicates with the outside through the mating hole for the installation of the anti-ship collision facility. The other end of the pre-embedded nut is sealed by an anchor rod, which is fixed to the pre-embedded steel plate. During construction, the pre-embedded steel plate fits snugly against the template, sealing the mating holes. This allows both ends of the pre-embedded nut to be sealed by the template and the anchor rod respectively, eliminating the need for holes in the template, facilitating template reuse. Furthermore, the pre-embedded steel plate and anchor rod can be easily connected and positioned to the steel reinforcement mesh of the construction site, simplifying construction and improving efficiency.
