Description

Technical Field

[0001] This application relates to the field of bridge construction auxiliary equipment technology, and in particular to a measuring point pre-embedded device for matching precast segmental bridges. Background Technology

[0002] In modern bridge construction, bridge segments are typically prefabricated within molds and then transported to the site for assembly. During the prefabrication process, precise embedded measuring points are installed to allow for accurate observation of the bridge's alignment using advanced equipment such as surveying robots. Traditional methods involve manually embedding these points on each bridge segment. This manual installation often results in inaccurate positioning, causing deviations in the measurement reference for the surveying robot. Consequently, this affects the robot's ability to measure the overall bridge alignment. Furthermore, the unevenness of the embedded points significantly hinders the robot's observations, reducing the accuracy and reliability of the data. Utility Model Content

[0003] In view of this, the purpose of this application is to propose a measuring point pre-embedded device for matching precast segmental bridges, so as to improve the positioning accuracy and flatness of the pre-embedded parts.

[0004] Based on the above objectives, this application provides a measuring point pre-embedded device for matching precast segmental bridges, used in conjunction with bridge molds. The bridge mold includes a casting space enclosed by a mold base plate and mold side plates. An installation platform is connected to the end of the mold side plate away from the mold base plate, and the casting space has a casting port. The pre-embedded device includes:

[0005] The positioning block and the positioning element are provided. One end of the positioning block is connected to the side of the mounting platform near the mold side plate, and the other end extends along a first direction to the top of the casting space and is connected to the positioning element. The positioning end of the positioning element extends along a second direction into the casting space.

[0006] An embedded sleeve is detachably connected to the positioning end of the positioning component, so as to be embedded in the concrete slurry in the pouring space along the first direction;

[0007] Wherein, the angle between the first direction and the mold side plate is a preset angle, the second direction is the direction from the pouring port to the mold bottom plate, and the first direction is perpendicular to the second direction.

[0008] Optionally, the positioning block and the mounting platform are provided with a first mounting hole, and a first connecting member is provided in the first mounting hole.

[0009] Optionally, the positioning member has a positioning hole at one end away from the first mounting hole, and the positioning member passes through the positioning hole and is connected to the positioning hole.

[0010] Optionally, multiple positioning blocks are provided and connected sequentially along the first direction. A second through mounting hole is provided on two adjacent positioning blocks, and a second connecting member is provided in the second mounting hole. The multiple positioning blocks have a free end, and the positioning member is provided on the free end. The positioning end of the positioning member extends into the casting space along the second direction.

[0011] Optionally, the embedded sleeve has an internal thread, the positioning member has an external thread, and the positioning member is threadedly connected to the embedded sleeve.

[0012] Optionally, the positioning hole is a threaded hole, and the positioning hole is threadedly connected to the positioning element.

[0013] Optionally, multiple positioning holes are provided.

[0014] Optionally, the pre-embedded sleeve is provided with anti-slip texture.

[0015] Optionally, the first mounting hole is a threaded hole, and the first connecting member is a fastening bolt.

[0016] Optionally, the outer surface of the pre-embedded sleeve is multi-faceted.

[0017] As can be seen from the above, the measuring point pre-embedding device provided in this application is used in conjunction with a bridge mold. The bridge mold includes a casting space enclosed by a mold base plate and a mold side plate. An installation platform is connected to one end of the mold side plate away from the mold base plate, extending away from the casting space. The casting space has a casting port. The pre-embedding device includes a positioning block, a positioning element, and a pre-embedding sleeve. The installation platform is located on the side of the mold side plate away from the mold side plate. One end of the positioning block is connected to the side of the installation platform near the mold side plate, and the other end extends along a first direction to the top of the casting space. The angle between the first direction and the mold side plate is a preset angle. The installation platform is used to stably install the positioning block, and the relative position of the installation platform and the positioning block is fixed. The positioning element is set on the positioning block, and its position is relatively fixed to the positioning block. The positioning element extends along a predetermined second direction into the casting space, allowing the pre-embedding sleeve to be accurately pre-embedded in each bridge segment with the guidance of the positioning element. The pre-embedded sleeves are positioned at the same location on each bridge segment. After the bridge segments are assembled into a whole bridge, the pre-embedded sleeves on the whole bridge are aligned in a row, so that the measurement reference of the measuring robot is the same. This effectively avoids the positioning error caused by manual pre-embedding, thereby improving the accuracy of the measuring robot's measurement data of the overall bridge alignment. The positioning block extends along the first direction to the top of the pouring space, and the positioning end of the positioning component extends along the second direction into the pouring space. The first direction is perpendicular to the second direction, and the positioning component is coaxial with the pre-embedded sleeve, so that the pre-embedded sleeve is vertically pre-embedded in the concrete slurry of the pouring space. This improves the flatness of the pre-embedded sleeve, and the pre-embedded sleeve is stably fixed in the concrete slurry by the positioning component, so that the pre-embedded sleeve will not tilt or shift during the concrete pouring and curing process. This allows the measuring robot to obtain the bridge alignment data more accurately when observing the bridge, reduces the measurement error caused by poor flatness of the pre-embedded component, and improves the reliability of the observation data.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0024] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains.

Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0025] As mentioned in the background, in modern bridge construction, prefabricated bridge segment technology, with its numerous advantages such as high efficiency, high quality, and environmental friendliness, has become an important development direction in the field of bridge construction. By prefabricating bridge segments in bridge molds in a factory and then transporting them to the site for assembly, not only can construction efficiency be improved, but the quality of the segments can also be effectively guaranteed. However, to ensure the overall safety and stability of the bridge, precise control of the bridge's three-dimensional geometric alignment is crucial. This requires accurately setting embedded measuring points during the prefabrication process so that advanced equipment such as measuring robots can be used for precise observation of the bridge alignment later.

[0026] Traditional methods for setting up embedded parts for measuring points have several drawbacks. Firstly, the positioning methods used are often not precise enough, leading to misalignment of the embedded parts after bridge segments are connected into a whole. This misalignment results in misalignment of the measuring robot, causing deviations in the overall bridge measurement benchmark. Consequently, this affects the measuring robot's measurement of the bridge's overall alignment, leading to errors in subsequent measurement data and impacting the accuracy of controlling the bridge's overall alignment. This can ultimately affect the bridge's structural stress and service life. Secondly, traditional methods are cumbersome to operate, inefficient, and consume significant manpower and time. Furthermore, traditional techniques struggle to guarantee the flatness of the embedded parts, greatly hindering the measuring robot's observation and reducing the accuracy and reliability of the observation data.

[0027] Given the shortcomings of traditional technologies, there is an urgent need for a pre-embedded measuring point device that is compatible with prefabricated segmental bridges. This device would improve the positioning accuracy and flatness of the embedded parts, provide strong support for the accurate observation of measuring points by the measuring robot in the later stages, facilitate the measuring robot to acquire bridge alignment data more smoothly, reduce measurement errors caused by poor flatness of the embedded parts, and improve the reliability of the observation data.

[0028] The following is in conjunction with the appendix Figure 1-2 The embodiments of this application will be described in detail below.

[0029] like Figure 1 and Figure 2 As shown, a measuring point pre-embedded device for matching precast segmental bridges is used in conjunction with a bridge mold 01. The bridge mold 01 includes a casting space 013 enclosed by a mold base plate 011 and a mold side plate 012. One end of the mold side plate 012 away from the mold base plate 011 is connected to an installation platform 014 disposed away from the casting space 013. The casting space 013 has a casting inlet 0131. The pre-embedded device includes:

[0030] Positioning block 1 and positioning element 2, one end of the positioning block 1 is connected to the side of the mounting platform 014 near the mold side plate 012, and the other end extends along the first direction to the top of the casting space 013 and is connected to the positioning element 2, and the positioning end of the positioning element 2 extends along the first direction toward the casting space 013;

[0031] The pre-embedded sleeve 3 is detachably connected to the positioning end of the positioning member 2, so as to be pre-embedded in the concrete slurry in the pouring space 013 along the first direction;

[0032] Wherein, the angle between the first direction and the mold side plate 012 is a preset angle, the second direction is the direction from the pouring port 0131 to the mold base plate 011, and the first direction is perpendicular to the second direction.

[0033] Specifically, the bridge mold 01 is a frame structure formed by the mold base plate 011 and the mold side plate 012. The casting space 013 within the frame structure contains concrete slurry. The pre-embedded sleeve 3 is embedded in the concrete slurry. After the concrete slurry solidifies, the positioning element 2 is separated from the pre-embedded sleeve 3, thus completing the pre-embedding of the pre-embedded sleeve 3. An installation platform 014 is provided on the side of the mold side plate 012 away from the mold side plate 012. One end of the positioning block 2 is connected to the installation platform 014 near the side plate 012, and its other end extends along a first direction above the casting space 013. The angle between the first direction and the mold side plate 012 is a preset angle; for example, this preset angle can be set to 90°. Figure 1 The arrow indicates the X direction. Mounting platform 014 is used to stably mount positioning block 1, and the relative position of mounting platform 014 and positioning block 1 is fixed. Positioning element 2 is mounted on positioning block 1, and its position is relatively fixed relative to positioning block 1. Positioning element 2 moves along a predetermined second direction (…). Figure 1 The arrow (in the Y direction) extends towards the pouring space 013, so that the pre-embedded sleeve 3 is precisely pre-embedded in the preset position of each bridge segment, and the position of the pre-embedded sleeve 3 on each bridge segment is the same. After the bridge segments are assembled into a whole bridge, the pre-embedded sleeves on the whole bridge are aligned in a row, so that the measurement reference of the measuring robot is the same, effectively avoiding the positioning error caused by manual pre-embedding, thereby improving the accuracy of the measuring robot's measurement data of the overall bridge alignment. The top surface of the mold side plate 012 is flush with the top surface of the mounting plane. The positioning block 1 simultaneously abuts against the top surface of the mold side plate 012 and the top surface of the mounting plane, so that the positioning block 1 extends along the first direction to the top of the pouring space (013). The positioning end of the positioning member 2 extends along the second direction toward the pouring space 013. The first direction is perpendicular to the second direction. The positioning member 2 is coaxial with the pre-embedded sleeve 3, so that the pre-embedded sleeve 3 is vertically pre-embedded in the concrete slurry of the pouring space 013, thereby improving the flatness of the pre-embedded sleeve 3. The pre-embedded sleeve 3 is stably fixed in the concrete slurry by the positioning member 2, so that the pre-embedded sleeve 3 will not tilt or shift during the concrete pouring and curing process. This allows the measuring robot to obtain the bridge alignment data more accurately when observing the bridge, reducing the measurement error caused by the poor flatness of the pre-embedded part and improving the reliability of the observation data.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, the positioning block 1 and the mounting platform 014 are provided with a through first mounting hole 11, and a first connector 4 is provided in the first mounting hole 11.

[0035] In addition, the first mounting hole 11 is a threaded hole, and the first connecting member 4 is a fastening bolt. The first connecting member 4 is threadedly connected to the first mounting hole 11, which facilitates the installation and disassembly of the positioning block 1, thereby improving the installation and disassembly efficiency of the positioning member 2.

[0036] In this embodiment, the first connector 4 is installed in the first mounting hole 11, which can accurately define the position of the positioning block 1, the mold side plate 012 and the mounting platform 014, thereby accurately defining the position of the positioning component 2 and the pre-embedded sleeve 3, ensuring that the position of the pre-embedded sleeve 3 on each section of the bridge is the same.

[0037] In some embodiments, such as Figure 1 and Figure 2 As shown, the positioning member 2 has a positioning hole 13 at one end away from the first mounting hole 11, and the positioning member 2 passes through the positioning hole 13 and is connected to the positioning hole 13.

[0038] In addition, the positioning hole 13 is a threaded hole, and the positioning hole 13 is threadedly connected to the positioning member 2. Multiple positioning holes 13 are provided.

[0039] Specifically, the threaded hole is set along the first direction to ensure that the positioning element 2 and the pre-embedded sleeve 3 are set along the second direction. The positioning element 2 is a fastening bolt, and the positioning hole 13 is threadedly connected to the positioning element 2, which facilitates the disassembly and installation of the positioning element 2 from the positioning hole 13, thereby improving the installation and disassembly efficiency of the positioning element 2. Multiple positioning holes 13 are provided, which makes it easy for the pre-embedded sleeve 3 to select the appropriate positioning hole 13 according to the preset pre-embedded position, thereby improving the versatility of the measuring point pre-embedded device.

[0040] In this embodiment, the positioning element 2 passes through and connects to the positioning hole 13. This connection provides strong stability and can effectively resist the influence of external forces (such as vibration, wind, etc.) on the position of the positioning element 2, thereby improving the overall structural stability. By precisely setting the position of the positioning hole 13 on the positioning element 2, the position of the positioning element 2 is precisely defined, thereby improving the accuracy of the pre-embedded position of the pre-embedded sleeve 3.

[0041] In some embodiments, the embedded sleeve 3 is provided with an internal thread, the positioning member 2 is provided with an external thread, and the positioning member 2 is threadedly connected to the embedded sleeve 3.

[0042] In this embodiment, the positioning element 2 is arranged along the second direction, and the pre-embedded sleeve 3 is threadedly connected to the positioning element 2, so that the pre-embedded sleeve 3 is kept in the state of being arranged along the second direction, so that the pre-embedded sleeve 3 is vertically pre-embedded in the concrete slurry in the pouring space 013 along the second direction. The threaded connection between the positioning element 2 and the pre-embedded sleeve 3 facilitates the quick installation and separation of the positioning element 2 and the pre-embedded sleeve 3, thereby improving the installation efficiency and disassembly efficiency of the positioning element 2.

[0043] In some embodiments, the pre-embedded sleeve 3 is provided with anti-slip texture.

[0044] In addition, the outer surface of the pre-embedded sleeve 3 is multi-faceted.

[0045] Specifically, the anti-slip texture can be raised dots, strips, or other geometric shapes, designed to increase the friction between the embedded sleeve 3 and the surrounding concrete or other materials, preventing the embedded sleeve 3 from sliding or shifting during use. To further improve the durability and adaptability of the embedded sleeve 3, special treatments such as galvanizing, powder coating, or coating can be applied to its outer surface to enhance its corrosion and wear resistance, while maintaining the clarity and effectiveness of the facets and anti-slip texture.

[0046] In this embodiment, the outer surface of the embedded sleeve 3 is multi-faceted to prevent rotation during subsequent use, thereby improving its stability and preventing interference with the measurement robot's measurement of the bridge's overall alignment. The anti-slip texture increases the friction between the embedded sleeve 3 and the surrounding concrete, further enhancing its stability during use.

[0047] In some embodiments, such as Figure 1 and Figure 3 The positioning blocks 1 are provided in multiple ways and are connected sequentially along the first direction. Two adjacent positioning blocks 1 are provided with a through second mounting hole 12. A second connecting member 5 is provided in the second mounting hole 12. The multiple positioning blocks 1 have a free end. The positioning member 2 is provided on the free end. The positioning end of the positioning member 2 extends into the casting space 013 along the second direction.

[0048] Specifically, positioning blocks 1 are sequentially connected along a first direction to form a positioning block assembly. Each positioning block 1 has a free end, meaning the entire positioning block assembly has a free end that is furthest from the installation platform 014. Positioning elements 2 are located on this free end, and their positioning ends extend along the first direction into the pouring space 013. This allows operators to flexibly adjust the length and layout of the entire positioning block assembly by increasing or decreasing the number of positioning blocks 1, thereby meeting the specific needs of different pre-embedded point distributions. Specifically, when multiple pre-embedded points need to be set within a large pouring space 013, a uniform and reasonable pre-embedded point layout can be easily achieved by adding or removing positioning blocks 1. The second mounting hole 12 is formed by connecting the positioning hole 13 on a positioning block 1 and the first mounting hole 11 on an adjacent positioning block 1. Both the positioning hole 13 and the first mounting hole 11 are threaded holes. The second connecting member 5 is a fastening bolt. By utilizing the existing positioning hole 13 and the first mounting hole 11 on the positioning block 1, the connection and disassembly between two adjacent positioning blocks 1 can be quickly realized through the second connecting member 5, which shortens the assembly and disassembly time of the positioning blocks 1 and improves the connection efficiency and disassembly efficiency between adjacent positioning blocks 1.

[0049] In this embodiment, multiple positioning blocks 1 are connected sequentially along the first direction, allowing operators to flexibly adjust the number of positioning blocks 1 according to the size of the pouring space 013 and the distribution requirements of the pre-embedded points, easily achieving a reasonable layout of multiple pre-embedded points within the pouring space 013. Adjacent positioning blocks 1 are provided with a through second mounting hole 12, and a second connector 5 is installed within the second mounting hole 12. By simply disassembling and installing the second connector 5, the connection and disassembly of adjacent positioning blocks 1 can be quickly completed, improving the efficiency of connection and disassembly between adjacent positioning blocks 1.
