Description

Technical Field

[0001] This invention relates to the field of steel structure truss technology, specifically to steel structure trusses and construction methods used in road and bridge engineering and building construction. Background Technology

[0002] Steel trusses are trusses made of steel. They are commonly used as the main load-bearing components in the roof structures, crane beams, and hydraulic gates of industrial and civil buildings.

[0003] After the truss is installed, due to the high strength and toughness of its steel structure, it mainly bears the heavy loads of hoisting and support. During operation, it will experience small swaying and deformation, which is common and therefore often overlooked for safety reasons. However, due to the metal fatigue property, the continuous deformation and swaying over a long period of time will cause the swaying and deformation to increase, eventually leading to safety hazards. However, since it is not possible to inspect the truss frequently, problems cannot be detected in time. Furthermore, the truss construction site depends on the work site, and the power supply and other facilities are difficult to provide, making it difficult to use electronic levels and other equipment continuously for extended periods. Therefore, a device is needed to alert when the truss sways or deforms excessively.

[0004] Therefore, it is essential to design steel trusses and construction methods that are highly practical and can promptly remind construction workers for use in road and bridge engineering and building construction. Summary of the Invention

[0005] The purpose of this invention is to provide steel trusses and construction methods for road and bridge engineering and building construction, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a steel structure truss for road and bridge engineering and building construction, including a crossbeam and a support beam. Both the crossbeam and the support beam have threaded holes, and bolts are threaded onto the inner walls of the threaded holes. The support beam and the crossbeam are fixedly connected by bolts. A slide rail is fixedly connected to the upper side of the outer wall of the crossbeam, and a cover plate is slidably connected to the outer wall of the slide rail. The lower surface of the outer wall of the cover plate contacts the upper side of the outer wall of the crossbeam. The cover plate is located above the bolts. An installation groove is provided on the front side of the crossbeam, and a prompting mechanism is provided inside the installation groove.

[0007] The prompting mechanism includes a connecting component and a plug and a stop bar on the connecting component. The stop bar can move inside the plug and the plug can move relative to the connecting component.

[0008] According to the above technical solution, the connecting assembly includes a fixing plate, the rear side of which is fixedly connected to the front side of the mounting groove, and a glass tube fixedly connected to the front side of the fixing plate. The glass tube is a hollow glass cover structure, and a sliding hole is provided on the glass tube. The inner wall of the sliding hole is slidably connected to the outer wall of the insert block. The lower end of the insert block is located inside the glass tube, and a float is fixedly connected to the lower end of the insert block. The upper end of the insert block is located outside the glass tube, and a slot is provided at the upper end of the insert block. A circular hole penetrating the upper and lower parts of the insert block is provided in the middle part of the insert block. A pigment groove is provided on the middle side wall. A first spring is fixedly connected to the bottom of the inner side wall, and a stop bar is fixedly connected to the upper end of the first spring. The outer wall of the stop bar is slidably connected to the inner wall of the insert block. An alarm mechanism is provided on the upper side of the insert block.

[0009] According to the above technical solution, the vertical height of the pigment tank is less than the vertical height of the stop rod, and the front-to-back thickness of the pigment tank is less than the diameter of the stop rod. The lower end of the stop rod is located on the lower side of the pigment tank, and the upper end of the stop rod is located on the upper side of the pigment tank. The upper end of the stop rod is at the same height as the bottom of the inner wall of the slot, and the first spring is in a compressed state when the upper end of the stop rod is at the same height as the bottom of the inner wall of the slot.

[0010] According to the above technical solution, the alarm mechanism includes a signal transmitter, the outer wall of which is fixedly connected to the outer wall of the crossbeam. The alarm mechanism also includes a first fixing post, the outer wall of which is fixedly connected to the outer wall of the crossbeam. A threaded rod is threadedly connected to the inner wall of the first fixing post. One end of the threaded rod is rotatably connected to a limit hook via a bearing. The lower surface of the limit hook contacts the lower surface of the inner wall of the slot. The outer side of the limit hook, away from the threaded rod, contacts the outer side of the insert block. A second spring is fixedly connected to the outer wall of the limit hook. The other end of the second spring is fixedly connected to the outer wall of the first fixing post. The threaded rod is rotatably connected to the limit hook. One end of the positioning hook is fixedly connected to a rotating rod. A rotating post is fitted on the outer wall of the rotating rod away from the positioning hook. A second fixed post is rotatably connected to the outer wall of the rotating post through a bearing. One side of the outer wall of the second fixed post is fixedly connected to the outer wall of the crossbeam. A coil is fixedly connected to the inner wall of the rotating post. The middle part of the coil is located on the side of the rotating post away from the first fixed post. Both ends of the coil pass through the rotating post and extend to the side of the rotating post near the positioning hook. A first conductive ring and a second conductive ring are fixedly connected to both ends of the coil, respectively. The alarm mechanism also includes a fixed ring. The outer wall of the fixed ring is fixedly connected to the outer wall of the crossbeam. Several magnets are fixedly connected to the inner wall of the fixed ring.

[0011] According to the above technical solution, the middle part of the coil forms a U-shaped structure, and the coil is located in the middle of the fixed ring. The surfaces of two adjacent magnets near the coil are opposite magnetic poles.

[0012] According to the above technical solution, the glass tube is a hollow transparent glass structure with a high center and flat sides. The center of the glass tube is filled with transparent liquid, and the upper part of the center of the glass tube is not filled with liquid and contains air bubbles. The pigment tank is filled with red pigment, and the outer wall of the stop bar is in contact with the inner wall.

[0013] The construction method for steel trusses used in road and bridge engineering and building construction involves using a crane to lift the required support beams and place them vertically on the foundation piles. After fixing the support beams to the precast foundation piles, the fixing bolts are installed for further fixation. Then, the crane lifts the crossbeams and places them on the support beams. The threaded holes on the crossbeams and support beams are aligned, and bolts are screwed into the crossbeams and support beams for fixation. Subsequently, reinforcing ribs and other precast components are installed on the crossbeams and support beams in sequence to achieve fixation. Finally, the signal transmitter and prompting mechanism are fixed inside the installation groove.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention completes the support function by setting up a structure with crossbeams, bolts, support beams and other structures, so that the structure can be stabilized and the components can be installed on its surface.

[0015] By installing a cover plate, the lower side of the cover plate can be moved to the upper side of the bolt, thus shielding the upper side of the bolt and preventing the bolt from being affected by external rainwater and dust. This makes the connection between the bolt and the support beam and crossbeam more stable, reduces the hidden dangers caused by rust and other issues, and achieves the purpose of reducing the causes of deformation of the support beam and crossbeam.

[0016] By incorporating a warning mechanism, this device can change its internal color when the deformation and sway of the support beam are significant, thereby alerting construction workers.

[0017] This device is equipped with a feature that allows it to sound an alarm for danger even when there is no power supply for an extended period of time. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-6 The present invention provides a technical solution: a steel structure truss for road and bridge engineering and building construction, including a crossbeam 1 and a support beam 7. Both the crossbeam 1 and the support beam 7 are provided with threaded holes, and bolts 2 are threadedly connected to the inner walls of the threaded holes. The support beam 7 and the crossbeam 1 are fixedly connected by bolts 2. A slide rail 3 is fixedly connected to the upper side of the outer wall of the crossbeam 1. A cover plate 4 is slidably connected to the outer wall of the slide rail 3. The lower surface of the outer wall of the cover plate 4 contacts the upper side of the outer wall of the crossbeam 1. The cover plate 4 is located above the bolts 2. An installation groove 5 is provided on the front side of the crossbeam 1. A prompting mechanism 6 is provided inside the installation groove 5. The prompting mechanism 6 includes a connecting component and a plug 603 and a stop bar 609 on the connecting component. The stop bar 609 can move inside the plug 603, and the plug 603 can move relative to the connecting component.

[0028] In use, after connecting the support beam 7 to the precast pile, the crossbeam 1 and support beam 7 are fixed with bolts 2. Then, the remaining components can be installed on the crossbeam 1 and support beam 7. After the bolts 2 are installed, the cover plate 4 is slid so that the lower side of the cover plate 4 moves to the upper side of the bolts 2, so that the upper side of the bolts 2 is covered by the cover plate 4, so that the bolts 2 are not affected by external rain and dust. This makes the connection between the bolts 2 and the support beam 7 and crossbeam 1 more stable, reduces the hidden dangers caused by rust and other conditions, and achieves the purpose of reducing the causes of deformation of the support beam 7 and crossbeam 1.

[0029] The connecting assembly includes a fixing plate 601, the rear side of which is fixedly connected to the front side of the mounting groove 5. A glass tube 602 is fixedly connected to the front side of the fixing plate 601. The glass tube 602 is a hollow glass cover structure. A sliding hole is provided on the glass tube 602. The inner wall of the sliding hole is slidably connected to the outer wall of the insert 603. The lower end of the insert 603 is located inside the glass tube 602. A float 604 is fixedly connected to the lower end of the insert 603. The upper end of the insert 603 is located outside the glass tube 602. A slot 605 is provided at the upper end of the insert 603. A hole 606 is provided in the middle of the insert 603. The hole 606 is a circular hole that passes through the top and bottom of the insert 603. A pigment groove 607 is provided on the middle side wall of the insert 606. A first spring 608 is fixedly connected to the bottom of the inner side wall of the insert 606. A stop bar 609 is fixedly connected to the upper end of the first spring 608. The outer wall of the stop bar 609 is connected to the outer wall of the insert 603. The inner wall of 606 is slidably connected. The glass tube 602 is a hollow transparent glass structure with a high middle section and flat sides. The middle section of the glass tube 602 is filled with transparent liquid. The upper part of the middle section of the glass tube 602 is not filled with liquid and contains air bubbles. The pigment tank 607 is filled with red pigment. The outer wall of the stop bar 609 is in contact with the inner wall of 606. An alarm mechanism 610 is provided on the upper side of the insert block 603. The vertical height of the pigment tank 607 is less than the vertical height of the stop bar 609. The front and rear thickness of the pigment tank 607 is less than the diameter of the stop bar 609. The lower end of the stop bar 609 is located on the lower side of the pigment tank 607. The upper end of the stop bar 609 is located on the upper side of the pigment tank 607. The upper end of the stop bar 609 is at the same height as the bottom of the inner wall of the slot 605. When the upper end of the stop bar 609 is at the same height as the bottom of the inner wall of the slot 605, the first spring 608 is in a compressed state.

[0030] While the crossbeam 1 and support beam 7 are shaking, the height of the left and right sides of the crossbeam 1 will change, causing the crossbeam 1 to tilt. This causes the liquid bubbles inside 702 to move to one side. When the deformation or tilt angle of the crossbeam 1 is too large, the bubbles will quickly move to the lower side of the float 604. Since the density of the float 604 is less than the density of the liquid inside 702 but greater than the density of the bubbles, the float 604 will be in an upward state when 702 is horizontal. After the float 604 encounters the bubbles, its lower side loses buoyancy, causing the insert 603 to move downward. After the insert 603 moves downward, the stop lever 609 moves upward relative to the insert 603 due to the elastic force of the first spring 608. This causes the lower side of the stop lever 609 to move to the middle of the pigment tank 607, allowing the dye inside the pigment tank 607 to flow into the interior of 702, dyeing the liquid inside 702 and making it conspicuous to remind the staff.

[0031] The alarm mechanism 610 includes a signal transmitter 101, the outer wall of which is fixedly connected to the outer wall of the crossbeam 1. The alarm mechanism 610 also includes a first fixing post 102, the outer wall of which is fixedly connected to the outer wall of the crossbeam 1. A threaded rod 103 is threadedly connected to the inner wall of the first fixing post 102. One end of the threaded rod 103 is rotatably connected to a limit hook 104 via a bearing. The lower surface of the limit hook 104 contacts the lower surface of the inner wall of the slot 605. The outer wall of the limit hook 104 away from the threaded rod 103 contacts the outer wall of the insert block 603. A second spring 105 is fixedly connected to the outer wall of the limit hook 104. The other end of the second spring 105 is fixedly connected to the outer wall of the first fixing post 102. A rotating rod 106 is fixedly connected to the end of the threaded rod 103 away from the limit hook 104. A rotating rod is sleeved on the outer wall of the rotating rod 106 away from the limit hook 104. The outer wall of the rotating pile 107 is rotatably connected to the second fixed pile 108 via a bearing. One side of the outer wall of the second fixed pile 108 is fixedly connected to the outer wall of the crossbeam 1. The inner wall of the rotating pile 107 is fixedly connected to the coil 109. The middle part of the coil 109 is located on the side of the rotating pile 107 away from the first fixed pile 102. Both ends of the coil 109 pass through the rotating pile 107 and extend to the side of the rotating pile 107 near the limit hook 104. The two ends of the coil 109 are respectively fixedly connected to the first conductive ring 110 and the second conductive ring 111. The alarm mechanism 610 also includes a fixed ring 112. The outer wall of the fixed ring 112 is fixedly connected to the outer wall of the crossbeam 1. Several magnets 113 are fixedly connected to the inner wall of the fixed ring 112. The middle part of the coil 109 forms a U-shaped structure. The coil 109 is located in the middle of the fixed ring 112. The surfaces of two adjacent magnets 113 near the coil 109 have opposite magnetic poles.

[0032] Before use, the outer walls of the first conductive ring 110 and the second conductive ring 111 are electrically connected to the signal transmitter 101 via conductive slip rings. After the insert block 603 moves down, the second spring 105 will contract due to the loss of obstruction of the limiting hook 104, causing it to move towards the first fixed post 102. During this process, the limiting hook 104 pushes the threaded rod 103 to move. Since the outer wall of the threaded rod 103 is threadedly connected to the inner wall of the first fixed post 102, the threaded rod 103 will rotate while moving. This causes the rotating rod 106 to rotate, which in turn causes the rotating stake 107 and coil 109 to rotate. As the rotating stake 107 rotates, it causes the coil 109 to rotate and cut magnetic field lines between several magnets 113. This results in a current being generated in the path formed between the coil 109, the first conductive ring 110, the second conductive ring 111, and the signal transmitter 101. This causes the signal transmitter 101 to send an electrical signal to the signal receiving terminal set up by the staff, thus achieving the purpose of directly issuing a warning and facilitating the recording of the warning time.

[0033] Furthermore, this device requires no electricity and can operate for extended periods without a power supply.

[0034] The steel truss construction method for road and bridge engineering and building construction involves using a crane to lift the support beam 7 that meets the requirements and place it vertically on the foundation pile. After fixing the support beam 7 to the precast foundation pile, the fixing bolts are installed for fixation. Then, the crane lifts the crossbeam 1 and places it on the support beam 7. The threaded holes on the crossbeam 1 and the support beam 7 are aligned, and then the bolts 2 are screwed into the crossbeam 1 and the support beam 7 for fixation. Then, reinforcing ribs and other precast components are installed on the crossbeam 1 and the support beam 7 in sequence to achieve fixation. Finally, the signal transmitter 101 and the prompting mechanism 6 are fixed inside the mounting groove 5.
