Description

Technical Field

[0001] The present invention relates to the technical field of bridge connectors, in particular to a prefabricated bridge metal connector. Background Art

[0002] In actual bridge construction work, bridges usually need to be supported and installed with bridge rubber bearings. During bridge construction, bolts are usually passed through the bolt holes of the rubber bearings to connect to the bridge, and holes need to be drilled at the bottom of the bridge. The installation stability of the bridge bearings is directly related to the stability of the bridge. At present, it is not convenient to prefabricate and cast bridge bearing connectors during the casting work of bridges, which affects the installation stability of the bridge and is not convenient for automatic melting and adapting to the bolt hole positions. The manual adjustment method is inefficient and easy to loosen. It is also not convenient to test the deformation and displacement of the bridge after the connection is placed during the installation of the bridge, which affects the construction safety of the workers. It is also not convenient to understand the overall deformation of the bridge. At the same time, the traditional method of drilling holes at the bottom of the bridge is a destructive installation, and the workers directly use bolts to install after drilling.

Once the drilling is wrong, the damage to the bridge is irreversible.

[0018] The use of average test pieces in conjunction with bolt installation safety pieces can ensure that workers can only tighten the bolts when the bridge and the bridge support pedestal are kept level during connection work. This can ensure the accuracy of construction connections and prevent workers from operating incorrectly or in violation of regulations. By directly installing bolts before the bridge is accurately measured, it can ensure that when the bridge is subsequently fully placed on the bridge support connection, the rubber blocks in the bridge support are evenly stressed, ensuring service life and safety.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1 to 12 As shown:

[0034] The present invention provides a technical solution: a prefabricated bridge metal connector, comprising a pre-embedded conductive part 1, on which two bending detection parts 2 are installed, and the two bending detection parts 2 are respectively used to detect the bending deformation of the bridge; the pre-embedded conductive part 1 is installed with four level prompting parts 3; the four level prompting parts 3 are respectively used to prompt the horizontal changes of the bridge; the pre-embedded conductive part 1 is installed with a bolt adapter 4; the bolt adapter 4 is installed with a hot melt control part 5; the hot melt control part 5 is used to control the bolt adapter 4 to hot melt the bolt hole; the bolt adapter 4 is installed with a bolt mounting part Safety part 6; the bolt installation safety part 6 is used to prevent the bolt from being installed incorrectly; an averaging test piece 7 is installed on the bolt adapter 4; the averaging test piece 7 is used to control the retraction of the bolt installation safety part 6; the embedded conductive part 1 includes: an embedded disk 101 and an elastic connecting tube 102, there are four embedded disks 101, and the structures on the four embedded disks 101 are the same; the four embedded disks 101 are connected by four elastic connecting tubes 102; the four elastic connecting tubes 102 are all elastic hoses; the four elastic connecting tubes 102 are composed of two shorter and two longer elastic connecting tubes 102.

[0035] Among them, the embedded conductive part 1 also includes: an embedded frame 103, and the embedded frame 103 is fixedly installed on the four embedded plates 101 respectively; four through holes are provided on the four embedded plates 101 respectively; the embedded frame 103 is used to be embedded in the bridge concrete; the horizontal prompt part 3 includes: a horizontal prompt tube 301, a buoyancy block 302, a pressure sensor 303, and a closing plug 304, and the pressure sensor 303 is externally connected to a display; the SC-10N pressure sensor 303 can be used, and a matching display is used, the four embedded plates 101 are respectively fixedly installed with a horizontal prompt tube 301; the four horizontal prompt tubes 301 are respectively connected to the four embedded plates 101; the buoyancy block 302 is located inside the horizontal prompt tube 301; a circle of grooves is provided on the outside of the buoyancy block 302; the pressure sensor 303 is fixedly installed inside the horizontal prompt tube 301; the water The side of the flat prompt tube 301 is threadedly connected with a closing plug 304; the horizontal prompt tube 301 is filled with water; the horizontal prompt tube 301 is located in the hollow area inside the bridge, and the horizontal prompt member 3 is used in conjunction with the embedded conductive member 1 to be embedded in the bottom of the bridge. The embedded plate 101 can be directly connected to the bridge support, which is convenient for bolt installation and does not require tedious hole drilling. At the same time, it is convenient for the staff to perform bridge inclination detection after the bridge is fully installed on the bridge support, which can ensure the stability of the bridge. There is no need for the staff to perform regular inspections. The inspection is direct and accurate, and the bridge inclination displacement can be reflected by the pressure sensor 303. The inspection is direct and accurate. The horizontal plane buoyancy in the four horizontal prompt tubes 301 pushes the buoyancy block 302 to squeeze the pressure sensor 303, and the pressure can be detected in real time by the pressure sensor 303.

[0036] Among them, the bending detection part 2 includes: a crossing connecting tube 201, a concentric detection ring 202, an accuracy confirmation piece 203 and a bonding piece 204. There are two crossing connecting tubes 201, and the two crossing connecting tubes 201 are respectively located on the outside of the two longer elastic connecting tubes 102; the two ends of the two crossing connecting tubes 201 are respectively fixedly installed on the side of the embedded plate 101 on the same side; the outsides of the two longer elastic connecting tubes 102 are respectively sleeved with a row of concentric detection rings 202, and a row of concentric detection rings 202 are respectively located on the inside of the crossing connecting tube 201; three accuracy confirmation pieces 203 are respectively fixedly installed in the middle of the two longer elastic connecting tubes 102; three bonding pieces 204 are fixedly installed inside the crossing connecting tube 201, and the three bonding pieces 204 are respectively attached to the three accuracy confirmation pieces 203; the three accuracy confirmation pieces 203 and the three bonding pieces 204 are externally connected with indicator lights in series; the crossing connecting tube 201 and a row of concentric detection rings 202 are externally connected with indicator lights in series, using bending The bending detection part 2 can be used to detect the deformation of the bridge after installation, which can ensure the safety of the structure after the bridge is connected to the support. At the same time, the bending detection part 2 used can be pre-buried inside the bridge, which is not affected by the external environment and has better anti-corrosion effect. The structure can test the bending deformation of the bridge and perform accuracy testing before pouring construction to avoid deformation and other factors that occur when crossing the connecting pipe 201 before pouring, which causes the subsequent measured data to be inaccurate. The detection accuracy of the structure is ensured and it is more practical. If the elastic connecting pipe 102 is eccentric at the initial position and there is an error, the three accuracy confirmation pieces 203 and the three bonding pieces 204 cannot be all connected to each other and connected to electricity. The external series indicator light can be turned off to give a prompt. When the bridge collapses and bends in the middle due to factors such as weight, the concentric detection ring 202 will no longer cross the connecting pipe 201 concentrically, but will contact the inner wall of the connecting pipe 201 and can light up to give a prompt.

[0037] Among them, the bolt adapter 4 includes: a bolt adapter slider 401, an electric heating wire 4011 and a filling aluminum sleeve 402. Four bolt adapter sliders 401 are respectively installed on the four embedded disks 101; the structures on the four bolt adapter sliders 401 are the same; the upper and lower sides of the four bolt adapter sliders 401 are respectively slid and fitted on the inner side of the bolt adapter slider 401; a circle of electric heating wire 4011 is provided on the outer side of the bolt adapter slider 401; a filling aluminum sleeve 402 is sleeved on the bolt adapter slider 401, and the filling aluminum sleeve 402 is located in the through hole of the embedded disk 101; the hot melt control component 5 includes: a touch test sleeve 501 and a closing cover 502, the touch test sleeve 501 slides The touch test sleeve 501 is sleeved on the bolt adapter slider 401; the bottom of the touch test sleeve 501 is threadedly connected to the closing cover 502; a spring is connected between the touch test sleeve 501 and the bolt adapter slider 401, and the spring between the touch test sleeve 501 and the bolt adapter slider 401 is located inside the bolt adapter slider 401; the bottom of the touch test sleeve 501 and the closing cover 502 are inclined structures; the hot melt control component 5 also includes: a movable contact ring 503 and a fixed contact ring 504, the movable contact ring 503 is fixedly mounted on the touch test sleeve 501; the fixed contact ring 504 is fixedly mounted on the bottom of the bolt adapter slider 401; the movable contact ring 503 and the fixed contact ring 504 are aligned;The movable electric ring 503, the fixed electric ring 504 and the electric heating wire 4011 are connected in series with the power supply, and the hot melt control part 5 can be used in conjunction with the bolt adapter 4 to more flexibly adapt to the bolt hole of the bridge support, so as to avoid the bridge support from being unable to adjust its position after being installed on the pier. At this time, once the eccentricity between the threaded hole of the bolt adapter slider 401 and the bridge support is large, it is easy to cause difficulty in bolt installation. This structure can automatically adapt to avoid repeated adjustments by the staff. At the same time, this structure adopts a movable bolt adapter slider 401 with stronger adaptability, avoiding the staff from directly drilling holes at the bottom of the traditional bridge. Once the drilling is wrong, the damage to the bridge is irreversible. This structure uses the hot melt control part 5 to automatically detect the concentricity of the bolt installation. Once the concentricity is not up to standard, the filling aluminum sleeve 402 can be directly controlled to melt, so that the bolt adapter slider 401 can be moved to adapt to the bolt hole position. After the filling aluminum sleeve 402 cools down, the limiting stability of the bolt adapter slider 401 can be guaranteed. The structure is simple and can be reset. Reusable, more versatile, if the support hole and the touch test sleeve 501 have a large concentricity deviation, the touch test sleeve 501 cannot be fully inserted into the production hole. At this time, under the extrusion of the production hole, the touch test sleeve 501 will move up, driving the mobile contact ring 503 and the fixed contact ring 504 to fit and connect with the power, and the electric heating wire 4011 will be energized to melt the filling aluminum sleeve 402. At this time, the bolt adapter slider 401 is no longer limited by the filling aluminum sleeve 402, and with the inclined structure at the bottom of the closing cover 502, the touch test sleeve 501 can The bolt adapter slider 401 is squeezed by the edge of the support hole, driving the lateral displacement of the bolt adapter slider 401. After cooling, the filler aluminum sleeve 402 can surround the bolt adapter slider 401 for positioning. The positioning is stable and can automatically adapt, without the risk of loosening. This structure can ensure that the support hole and the touch test sleeve 501 are tightly connected, ensuring installation quality and avoiding the problem of excessive gaps between traditional bolts and support bolt holes. It is also more suitable for bridge construction and can automatically adapt to smaller eccentric deviations, reducing the installation difficulty for workers.

[0038] Embodiment 2, on the basis of embodiment 1, the bolt installation safety member 6 comprises: a safety plug shaft 601, a reset tension spring 602, an electromagnet 603 and a latch 604, the safety plug shaft 601 is slidably plugged into the bottom of the bolt adapter slider 401; the top of the safety plug shaft 601 is connected to a reset tension spring 602, and the other end of the reset tension spring 602 is connected to the inside of the bolt adapter slider 401; an electromagnet 603 is fixedly installed inside the safety plug shaft 601; a latch 604 is slidably plugged into the safety plug shaft 601, and the latch 604 and the safety plug shaft 601 are connected by a tension spring; the electromagnet 603 is aligned with the plug Pin 604; the average test piece 7 includes: a ring 701 and an upward spring 702, four rings 701 are slidably installed at the bottom of the four embedded disks 101, and the top of the ring 701 is connected to the upward spring 702; the top of the upward spring 702 is connected to the bottom of the embedded disk 101; the average test piece 7 also includes: an electrical spring 703, an electrical block 7031 and a bottoming rod 704, the side of the ring 701 is fixedly installed with an electrical spring 703; the bottom of the four embedded disks 101 are respectively embedded with an electrical block 7031, and the electrical block 7031 is aligned with the electrical spring 703; the side of the ring 701 is fixed Equipped with a bottoming rod 704; four power-connecting springs 703, power-connecting blocks 7031 and four electromagnets 603 on the same side are connected in series with the power supply, and an average test piece 7 is used in conjunction with a bolt installation safety piece 6 to ensure that when the workers are performing the connection work, the bridge and the bridge support pedestal are kept level before the bolts can be tightened. This can ensure the accuracy of the construction connection and prevent the workers from operating incorrectly or in violation of regulations. The bolts are directly installed before the bridge is accurately measured, resulting in errors in the bolt hole opening at the bottom of the bridge. This structure detection is direct and accurate, avoiding unnecessary damage to the bridge, and also helps Standardized construction precision control can ensure that when the subsequent bridge is fully placed on the bridge support connection, the rubber blocks in the bridge support are evenly stressed, ensuring service life and safety. When the bridge support is lowered and connected to the bridge support, if the bridge support pedestal and the four bottoming rods 704 are not parallel, the bottoming rods 704 cannot be squeezed by the bridge support pedestal at the same time, and the four power-connecting springs 703 and the power-connecting blocks 7031 cannot be contacted and energized at the same time. The safety plug shaft 601 will also block the bolt adapter slider 401, and the staff cannot install the bolts. Ensure that the bridge and the bridge support pedestal are level when the bolts are installed to ensure stability.

[0039] The working principle of this embodiment: First, after the pre-embedded conductive component 1 is pre-embedded in the bridge, water can be injected into the elastic connecting pipe 102. At this time, the horizontal buoyancy in the four horizontal prompt tubes 301 pushes the buoyancy block 302 to squeeze the pressure sensor 303. The pressure can be detected in real time by the pressure sensor 303. Once the bridge is skewed, the liquid level under the four buoyancy blocks 302 changes, and the corresponding pressure value detected by the pressure sensor 303 will also change, and the prompt work can be performed in real time. Before pouring and pre-embedding, the longer elastic connecting pipe 102 should be located in the middle of the spanning connecting pipe 201. At this time, the three precision confirmation pieces 203 on the outside of the longer elastic connecting pipe 102 are respectively attached to the bonding piece 204, and the three precision confirmation pieces 203 and the three bonding pieces 204 are respectively attached. The indicator lights connected in series on the outside of the fitting 204 can provide a prompt. On the contrary, if the elastic connecting tube 102 is eccentric in the initial position and there is an error, the three precision confirmation pieces 203 and the three fitting pieces 204 cannot all be connected to each other and connected to the electricity. The indicator lights connected in series on the outside can go out to provide a prompt. When the middle part of the bridge collapses and bends due to factors such as weight, the internal pre-buried spanning connecting tube 201 will also bend. At this time, the longer elastic connecting tube 102 is an elastic structure and can always maintain a linear tension state. At this time, the concentric detection ring 202 is no longer concentric with the spanning connecting tube 201, but contacts the inner wall of the spanning connecting tube 201. At this time, the spanning connecting tube 201 and the indicator lights connected in series on the outside of a row of concentric detection rings 202 will conduct the circuit and light up to provide a prompt. When the bridge is lowered When it reaches the bridge support, the touch test sleeve 501 and the closing cover 502 will be inserted into the bolt hole of the bridge support. If the concentricity deviation between the support hole and the touch test sleeve 501 is large, the touch test sleeve 501 cannot be fully inserted into the production hole. At this time, under the extrusion of the production hole, the touch test sleeve 501 will move up, driving the movable contact ring 503 and the fixed contact ring 504 to fit and connect with electricity. The electric heating wire 4011 will be energized to melt the filled aluminum sleeve 402. At this time, the bolt adapter slider 401 is no longer limited by the filled aluminum sleeve 402. With the inclined structure at the bottom of the closing cover 502, the touch test sleeve 501 can be squeezed by the edge of the support hole, driving the bolt adapter slider 401 to move laterally for adaptation, and the touch test sleeve 501 can be smoothly inserted into the support hole. At this time, the touch test sleeve 50 1 is no longer squeezed by the support. Under the pressure of the spring on the touch test sleeve 501, the touch test sleeve 501 can be moved down and reset. The electric heating wire 4011 will be powered off. After the filling aluminum sleeve 402 cools down, it can surround the bolt adapter slider 401 for positioning. The positioning is stable. When the bridge support is placed under the bridge, the four bottoming rods 704 touch the bridge support pedestal at the same time. At this time, under the pressure of the bridge support pedestal, the ring 701 is squeezed and moved upward, which can drive the four power-connecting springs 703 to fit the power-connecting block 7031 at the same time, and the electromagnet 603 can be controlled to magnetically attract the pin 604. The tension spring between the pin 604 and the safety plug shaft 601 is stretched, and the plug-in safety plug shaft 601 can be released. At this time, the reset tension spring 602 can pull the safety plug shaft 601 upward.The bolt adapter slider 401 is no longer blocked, and the staff can now install the bolts normally. On the contrary, if the bridge support cap is not parallel to the four bottoming rods 704, the bottoming rods 704 cannot be squeezed at the same time, and the four power connection springs 703 and the power connection block 7031 cannot be contacted and energized at the same time. The safety plug shaft 601 will still block the bolt adapter slider 401, and the staff cannot install the bolts.
