AI Technical Summary
After precast T-beams are hoisted to the construction position, they are easily affected by subsequent pouring operations or external factors, which can cause them to shift in position. This can lead to misalignment at the connection between two adjacent precast T-beams, reducing the quality of construction.
A combination of support base, T-beam positioning assembly and support bearing assembly is used to achieve precise positioning and calibration of the T-beam through electric slide, hydraulic drive and angle adjustment assembly, ensuring that the T-beam does not deviate from the preset position.
This effectively prevents T-beams from shifting during construction, ensures proper overlap at the connection points of adjacent T-beams, and improves construction quality and safety.

Abstract
Description
Technical Field
[0001] This invention relates to a precast T-beam construction device and method, belonging to the field of bridge construction technology. Background Technology
[0002] Currently, precast T-beams have become the most commonly used structural form for roads and bridges. As an important part of the bridge that bears the load, the construction quality of precast T-beams is related to the stress and safety of the entire bridge structure. Quality control during the construction and installation of precast T-beams is not only an important part of bridge construction, but also the key to protecting people's lives and property.
[0003] Currently, during the construction and installation of precast T-beams, the lower components such as piers and foundations are first installed at the construction site. Then, a gantry crane is erected at the construction site to lift the precast T-beams to the installation location. Prestressed steel bars are then inserted into the pre-embedded holes reserved during the production of the precast T-beams, and grouting sleeves are used to press grouting, so that the concrete fully fills the gap between the two precast T-beams, completing the assembly and fixing of the two adjacent precast T-beams.
[0004] However, after the precast T-beams are hoisted to the construction position, they are prone to displacement and slippage due to subsequent pouring operations or external factors. This displacement can cause misalignment of the lap joint when building steel frames at the connection between two adjacent precast T-beams, thus affecting the grouting effect and reducing the construction quality.

[0017] According to another aspect of the present invention, a method for constructing precast T-beams is provided.
[0018] The construction method for this precast T-beam includes the following steps:
[0019] The T-beam is lifted by a crane and placed in the support groove;
[0020] The controller drives the electric slide to move closer to the support groove on the slide rail until the clamping plate on the side of the moving frame clamps and limits the T-beam side.
[0021] When the motor is started, it drives the drive arm to rotate. The drive arm then drives the angle adjustment plate to slide and flip. Once the angle adjustment plate is upright, the clamping block at one end of the bottom will clamp and hold the T-beam in place.
[0022] When the hydraulic cylinder three and the hydraulic rod three are activated, they will extend and retract. The hydraulic rod three presses the support plate downward, and the support plate drives the U-shaped frame. When the U-shaped frame moves downward, the gear in the groove drives the side toothed plates that mesh on both sides. The side toothed plates press downward at the same time, so that the pressure plate presses against the ground or cover beam below, positioning the T-beam in the preset position.
[0023] After the T-beam is positioned and supported in the pre-set area, the motor is started to drive the drive arm to rotate in the opposite direction, pulling the slider three to slide in the grooves of L-shaped track plate one and L-shaped track plate two, driving the angle adjustment plate to slide down to form a horizontal position;
[0024] Activate the angle adjustment component on the top of the angle adjustment plate;
[0025] The hydraulic auxiliary unit in the angle adjustment assembly drives the support plate upward, adjusting the height of the angle adjustment assembly so that the angle adjustment assembly can be used at the position where the cross diaphragm overlaps between the tops of two adjacent T beams.
[0026] In the angle adjustment assembly, the hydraulic cylinder drives the hydraulic rod to perform telescopic movement. Through the pull rods on both sides, the horizontal plates on both sides are brought closer to the center simultaneously. The limit wheel is in contact with the horizontal diaphragm that overlaps between the tops of the two adjacent T beams. Under the pressure adjustment of the limit wheel, the angle of the horizontal diaphragm is calibrated so that the horizontal diaphragm and the T beam are kept in a vertical and close state.
[0027] The T-beams for positioning and calibration, as well as the overlapping diaphragms between them, are poured.
[0028] The beneficial effects of this invention are:
[0029] The T-beam is placed in the installation slot, and the T-beam in the middle is positioned and supported by the T-beam positioning components on both sides. Then, the support and bearing components on the other two sides are driven. The support and bearing components are driven by the moving components to calibrate the position of the T-beam, so that the T-beam is kept in the preset position and will not be displaced during the later pouring construction.
[0030] By setting symmetrical T-beam positioning components and support bearing components on several sides of the T-beam, lateral and longitudinal displacement can be achieved, and the T-beam can be clamped and adjusted in multiple ways to ensure that the T-beam is positioned and supported in a preset position, thus preventing the T-beam from shifting during operation.
[0031] The T-beam positioning assembly allows for tilt or horizontal rotation adjustment on both sides of the T-beam, meeting the installation requirements for complex T-beam alignments. Attached Figure Description

[0050] Example 2
[0051] A method for constructing precast T-beams includes the following steps:
[0052] S101: Use a crane to lift the T-beam 2 and place the T-beam 2 into the support groove 3;
[0053] S102: Drive the electric slide block 602 to move closer to the support groove 3 on the slide rail 601 by the controller until the clamping plate 702 on the side of the moving frame 701 clamps and limits the side of the T beam 2.
[0054] S103: Start the motor 411 to run. The motor 411 drives the drive arm 410 to rotate. The drive arm 410 drives the angle adjustment plate 407 to slide and flip. After the angle adjustment plate 407 is upright, the clamping block 412 at the bottom end will clamp and abut against the T beam 2 to position and clamp the T beam 2.
[0055] S104: Start the hydraulic cylinder 704 and hydraulic rod 705 to generate telescopic movement. Hydraulic rod 705 presses the support plate 706 downward. The support plate 706 drives the U-shaped frame 707. When the U-shaped frame 707 moves downward, the gear 708 in the groove drives the side toothed plates 709 that mesh on both sides. The side toothed plates 709 press down at the same time, so that the pressure plate 711 presses against the ground or cover beam below, positioning the T-beam 2 in the preset position.
[0056] S105: After the T-beam 2 is positioned and supported in the preset area, the motor 411 is started to drive the drive arm 410 to rotate in the opposite direction, pulling the slider 3 408 to slide in the groove of L-shaped track plate 1 401 and L-shaped track plate 2 402, driving the angle adjustment plate 407 to slide down to form a horizontal position.
[0057] S106: Activate the angle adjustment assembly 5 on the top of the angle adjustment plate 407;
[0058] S107: The hydraulic auxiliary part in the angle adjustment component 5 drives the support plate 501 upward to adjust the height of the angle adjustment component 5, so that the angle adjustment component 5 is suitable for the position where the cross diaphragm between the tops of two adjacent T beams 2 overlaps.
[0059] S108: The hydraulic cylinder 524 in the angle adjustment assembly 5 drives the hydraulic rod 523 to perform telescopic movement. The pull rods 508 on both sides bring the horizontal plates 509 on both sides closer to the center at the same time. The limiting wheel 515 is in contact with the horizontal diaphragm that overlaps between the tops of the two adjacent T beams 2. Under the pressure adjustment of the limiting wheel 515, the angle of the horizontal diaphragm is calibrated so that the horizontal diaphragm and the T beam 2 are kept in a vertically attached state.
[0060] S109: Cast the T-beam 2 and the overlapping diaphragms between them for positioning and calibration.
[0061] The circuits and electronic components, modules and controllers, or the heat dissipation holes and maintenance doors in the space of the adapted electrical equipment are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this application does not involve improvements to software and methods or heat dissipation and maintenance.
[0062] In use, the T-beam 2 is lifted by a crane and placed in the support groove 3. The motor 411 is started and runs. The motor 411 drives the drive arm 410 to rotate. When the drive arm 410 rotates to one side of the T-beam 2, it drives the limit rod 2 409 to flip to one side of the T-beam 2. The slider 3 408 on the right side of the angle adjustment plate 407 will slide to the left in the groove of the L-shaped track plate 1 401 and the L-shaped track plate 2 402 until it slides to the corner end of the L-shaped track plate 1 401 and the L-shaped track plate 2 402. At this time, the angle adjustment plate 407 is in a vertical state, and the clamping block 412 on the side end of the angle adjustment plate 407 clamps and positions the side of the T-beam 2.
[0063] The controller controls the electric slide block 602, causing it to slide on the slide rail 601, which in turn moves the moving frame 701 toward the T-beam 2. The other two sides of the T-beam 2 are then engaged in the grooves formed between the clamping plates 702. The hydraulic cylinder 704 and the hydraulic rod 705 are then activated to extend and retract. The hydraulic rod 705 presses the support plate 706 downward, which in turn moves the U-shaped frame 707 downward. The gear 708 in the groove of the U-shaped frame 707 moves downward, and the gear 708 meshes with the tooth grooves of the side tooth plates 709 on both sides. When the gear 708 moves downward, it will move the side tooth plates 709 on both sides downward, causing the pressure plate 711 to press against the cap beam or ground below. When the two sides are uneven, the pressure plates 711 on both sides will always remain in contact due to the action of the gear 708.
[0064] After positioning and clamping the T-beam 2, start the motor 411 to drive the drive arm 410 to rotate in the opposite direction. The sliders 408 on the right side of the angle adjustment plate 407 slide to the right along the L-shaped track plates on both sides. After the angle adjustment plate 407 is tilted, it forms a parallel state with the support seat 1.
[0065] Start the extension and retraction movement of hydraulic cylinder 504 and hydraulic rod 505. Hydraulic rod 505 pushes the support plate 501 upward, supporting the support plate 501 to the horizontal plane of the top surface of T beam 2. Start the extension and retraction movement of hydraulic cylinder 524 and hydraulic rod 523. Hydraulic rod 523 pulls the horizontal plate 509 connected on one side towards the center. Under the action of pull rod 508 and rotating plate 507, pull the two horizontal plates 509 towards the center simultaneously. When the limit wheel 515 abuts against the diaphragm wall of the truss between adjacent T beams 2, the diaphragm is corrected so that the diaphragm and T beam 2 are in a vertical state, avoiding the displacement or inaccurate position at the joint.
[0066] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
