Description

Technical Field

[0001] This invention relates to the field of crash barriers, specifically a crash barrier steel reinforcement positioning frame and positioning method. Background Technology

[0002] The crash barrier reinforcement positioning frame is a special template used in the construction of crash barriers. As an auxiliary structure of bridges or highways, crash barriers are very important safety protections, and the shape and surface smoothness of the crash barriers directly affect the aesthetics and quality of bridges or highways.

[0003] The positioning frame for crash barriers typically consists of a front mold and a rear mold, which are fixed together with steel bars. Then, concrete is poured in, and after solidification, the crash barrier is formed. The different protective thicknesses of different crash barriers are achieved by controlling the distance between the front and rear molds. This requires personnel to frequently replace steel bars of different lengths connecting the front and rear molds. If the installation and removal of steel bars are inconvenient, it will damage the front and rear molds and increase the difficulty of operation for construction personnel. Summary of the Invention

[0004] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides a positioning frame and positioning method for anti-collision wall steel reinforcement.

[0005] The present invention is implemented as follows: a positioning frame and positioning method for anti-collision wall steel reinforcement are constructed. The device includes a stiffening plate, a back rib, an adjusting pile and a panel. The back rib is installed on the side of the stiffening plate, the adjusting pile is installed on the top of the panel, and the stiffening plate is welded to the panel.

[0006] It also includes a pile block, a recessed seat, a fixing rod, and a first locking block. The recessed seat and the pile block are an integral structure. The two ends of the fixing rod rest on the recessed seat. The first locking block is threaded to the side end of the fixing rod. The first locking block is located on the outer side of the recessed seat. The recessed seat is set in the pile block so that the whole is concave, which facilitates the spacing control by the fixing rod.

[0007] Preferably, the panel includes a frame, a positioning seat, a through rod, a second locking block, and a reinforcing bar. The positioning seat is located at the lower outer side of the frame. The through rod passes through the lower end of the frame and through the center of the positioning seat. The second locking block is threaded to the side end of the through rod and is movably fitted on the outer end face of the positioning seat. The front and rear ends of the reinforcing bar can be embedded in the frame and movably engaged.

[0008] Preferably, the plate frame includes a plate body, an inner groove, a movable body, a side opening, an installation opening, a snap-fit ​​groove, and a slide rail. The inner groove is an integral structure with the plate body and is located inside it. The side opening is located on the end face of the plate body. The movable body is loosely fitted and movable inside the side opening. The installation opening is embedded in one side of the inner groove and is interconnected. The slide rail is located next to the snap-fit ​​groove, which is located above and below the installation opening. One end face of the plate frame is an end panel with fifteen holes. The holes provide a locking mechanism for inserting reinforcing bars. The inner groove is empty, providing movement space for the movable body. The side opening provides a movement trajectory for the movable body, allowing it to engage and disengage from the snap-fit ​​groove, thereby tightening and loosening the side end of the reinforcing bar, facilitating the replacement of the reinforcing bar, and allowing the spacing between the front and rear plate frames to vary, thus enabling the casting of anti-collision walls of different thicknesses.

[0009] Preferably, the movable body is provided with a pressing handle, a pressing frame, a buckle structure and a fixing plate. One side end of the pressing frame is fixedly connected to the inner end face of the pressing handle. The upper and lower ends of the buckle structure are respectively connected to the pressing frame and are movably engaged. Adjacent buckle structures are connected to each other through the fixing plate.

[0010] Preferably, the snap-fit ​​structure includes a solid plate, a sliding groove, a connecting ring, a locking block, a spring, and a locking slot. The sliding groove and the solid plate are an integral structure and pass through each other. The connecting ring is connected to the inner side of the solid plate. The locking block is slidably engaged with the sliding groove. The spring is connected to the end of the locking block and is movably engaged. The locking slot is located on the inner side of the connecting ring.

[0011] Preferably, the connecting ring includes an outer ring, an inner ring, a supporting structure, and a fitting block. The supporting structure is provided between the outer ring and the inner ring and is movably fitted. The fitting block is tightly fitted to the inner wall of the inner ring.

[0012] Preferably, the support structure includes a swing arm, a stop block, and a spring steel. The stop block is hinged to the bottom end of the swing arm. Spring steel is connected to each swing arm and is movably fitted. The support structure has three swing arms, and a spring steel is provided between each pair of swing arms to facilitate the adjustment of the included angle between the swing arms and assist in changing the magnitude of the support force.

[0013] Preferably, the pressure frame is located above and below the snap-fit ​​structure. When the pressing handle is pressed, the pressure frame moves accordingly, pressing the snap-fit ​​block into the sliding groove, making it easy for the snap-fit ​​block to disengage from the snap-fit ​​groove. Then, the snap-fit ​​structure as a whole moves with the pressing handle, thereby loosening the fastening to the side end of the reinforcing bar, making it convenient to install and remove the reinforcing bar.

[0014] Preferably, the inner ring is made of soft resin, has a certain degree of deformability, and is ring-shaped. The bonding block is made of rubber, has a certain degree of flexible deformation force, and after being bonded to the outer circumference of the reinforcing bar, it has a good anti-slip effect and better clamping force. The support structure has twenty-four parts between the outer ring and the inner ring, and is evenly distributed in a ring shape about the center of the outer ring, which provides deformation support between the outer ring and the inner ring, allowing the diameter of the bonding block to vary, and enabling more flexible clamping installation for reinforcing bars with different diameters.

[0015] The present invention has the following advantages: The present invention provides an improved anti-collision wall rebar positioning frame and positioning method, which, compared with similar equipment, has the following improvements:

[0016] This invention discloses a positioning frame and method for positioning reinforcing bars in a crash barrier. By incorporating adjusting stakes, the two ends of the fixing rod are positioned differently above the recessed seat, thus assisting the control panel in adjusting the front-to-back spacing. A movable body is included; when a person presses the pressing handle, the pressure is transmitted to the locking block, causing it to sink into the sliding groove. This allows the movable body to deform, and the person then moves the entire movable body along the side opening until the locking opening engages with the side end of the reinforcing bar. At this point, the movable body is vertically positioned inside the locking groove. Releasing the pressing handle allows the locking block to be pushed into the locking groove under the elastic action of the spring, fixing the overall position of the locking structure and achieving secure installation of the reinforcing bar. A connecting ring is incorporated, allowing the fitting block to be subjected to the penetrating force of the reinforcing bar, transmitting the pressure to the abutment block. The support structure generates flexible support between the outer and inner rings, facilitating the inner ring's engagement with the resilient fitting block. This allows for flexible changes in the locking opening's diameter, enabling more flexible clamping installation of reinforcing bars with varying diameters. Attached Figure Description

[0028] Please see Figure 3-4This invention discloses a positioning frame and method for a steel reinforcement in a crash barrier. The panel 4 includes a frame 41, a positioning seat 42, a through rod 43, a second locking block 44, and a steel reinforcement 45. The positioning seat 42 is located on the outer side of the bottom of the frame 41. The through rod 43 passes through the lower end of the frame 41 and through the center of the positioning seat 42. The second locking block 44 is threaded to the side end of the through rod 43 and is movably fitted on the outer end face of the positioning seat 42.

The holes provide a locking mechanism for the insertion of the reinforcing bar 45. The inner groove 412 is empty, providing space for the movable body 413 to move. The side opening 414 provides a movement trajectory for the movable body 413, allowing it to engage and disengage from the snap-fit ​​groove 416, thereby securing and releasing the side end of the reinforcing bar 45, facilitating the replacement of the reinforcing bar 45. This allows the spacing between the front and rear plate frames 41 to vary, thus enabling the casting of anti-collision walls of different thicknesses.

[0029] Please see Figure 5-6 This invention discloses a positioning frame and method for anti-collision wall reinforcement. The movable body 413 is provided with a pressing handle a1, a pressing frame a2, a snap-fit ​​structure a3, and a fixing plate a4.

[0030] Please see Figure 7-8This invention discloses a positioning jig and method for anti-collision wall reinforcement. The connecting ring a33 includes an outer ring q1, an inner ring q2, a supporting structure q3, and a fitting block q4. The supporting structure q3 is provided between the outer ring q1 and the inner ring q2 and is movably fitted. The fitting block q4 is tightly fitted to the inner wall of the inner ring q2. The supporting structure q3 includes a rocker arm q31, a stop block q32, and a spring steel q33. The stop block q32 is hinged to the bottom end of the rocker arm q31. Spring steel q33 is movably fitted between each rocker arm q31. The supporting structure q3 has three rocker arms q31, and a spring steel q33 is provided between each pair of rocker arms q31. Q33 facilitates the adjustment of the included angle between the swing rods Q31, assisting in varying the magnitude of the support force. The inner ring Q2 is made of soft resin, possessing a certain degree of deformability and a ring shape. The bonding block Q4 is made of rubber, possessing a certain degree of flexible deformation force, and after being bonded to the outer circumference of the reinforcing bar 45, it has a good anti-slip effect and better clamping force. The support structure Q3 has twenty-four pieces between the outer ring Q1 and the inner ring Q2, and is evenly distributed in a ring shape around the center of the outer ring Q1, providing deformation support between the outer ring Q1 and the inner ring Q2. This allows the diameter and width of the bonding block Q4 to be varied, enabling more flexible clamping installation for reinforcing bars 45 with different diameters and widths.

[0031] This invention provides an improved positioning frame and positioning method for anti-collision wall steel reinforcement, the working principle of which is as follows;

[0032] First, when using this equipment, by allowing the two ends of the fixing rod 33 to be placed above the recessed seat 32 and the position to be adjusted by the user, the length of the fixing rod 33 protruding outward from the recessed seat 32 is different. The first locking block 34 then threadedly connects the fixing rod 33 to the pile block 31 to lock and fix it, thereby assisting the control panel 4 in adjusting the front and rear spacing.

[0033] Second, during installation, after the reinforcing bar 45 is inserted into the installation port 415, the operator presses the pressing handle a1, causing the pressure frame a2 to be compressed and the pressure transmitted to the locking block a34, causing it to sink into the sliding groove a32. This allows the movable body 413 to deform, and the operator then moves the movable body 413 along the side opening 414 until the locking slot a36 engages with the side end of the reinforcing bar 45. At this point, the movable body 413 is vertically positioned inside the locking groove 416. The operator then releases the pressing handle a1, and under the elastic action of the spring a35, the... The locking block a34 is pushed into the locking groove 416, which fixes the position of the locking structure a3 as a whole, thus fixing the steel bar 45 in place. When the steel bar 45 is to be removed, the operator presses the pressing handle a1, which causes the connecting ring a33 with deformation force and the spring a35 to assist the locking block a34 in displacement, so that the locking block a34 is disengaged from the locking groove 416, and the moving body 413 moves a certain distance along the slide 417, and then moves to the inside of the side opening 414, thereby releasing the pressure on the steel bar 45, which facilitates the installation and removal of the steel bar 45.

[0034] Third, through the annular shape of the inner ring q2 and its inherent toughness and deformation properties, as well as the setting of the support structure q3, the support structure q3 forms a uniform annular distribution at the distance between the outer ring q1 and the inner ring q2. The bonding block q4 is subjected to the penetrating force of the steel bar 45, which transmits the pressure to the abutment block q32. The swing rod q31 swings with the force on the abutment block q32. The spring steel q33 assists in controlling the angle change between the swing rods q31, so that the support structure q3 can generate a flexible supporting force between the outer ring q1 and the inner ring q2. This facilitates the inner ring q2 to cooperate with the tough bonding block q4, and allows for flexible changes in the diameter of the clamp a36, enabling more flexible clamping and installation of steel bars 45 with different diameters.

[0035] This invention provides an improved positioning frame and method for anti-collision wall rebar positioning. By incorporating adjusting stakes 3, the two ends of the fixing rod 33 are positioned differently above the recessed seat 32, thus assisting the control panel 4 in adjusting its front-to-back spacing. A movable body 413 is included; when a person presses the pressing handle a1, the pressure frame a2 is compressed and the pressure is transmitted to the locking block a34, causing it to sink into the sliding groove a32. This allows the movable body 413 to deform, and the person then moves the movable body 413 along the side opening 414 until the locking opening a36 engages with the side end of the rebar 45. At this point, the movable body 413 is vertically positioned in the locking position. Inside the groove 416, when the operator releases the pressing handle a1, the spring a35 pushes the locking block a34 into the locking groove 416, thus fixing the position of the locking structure a3 and securing the rebar 45. By setting the connecting ring a33, the fitting block q4 is subjected to the penetrating force of the rebar 45, transmitting the pressure to the abutment block q32. The support structure q3 can generate a flexible supporting force between the outer ring q1 and the inner ring q2, facilitating the cooperation between the inner ring q2 and the resilient fitting block q4. This allows for flexible changes in the diameter of the locking slot a36, enabling more flexible clamping and installation of rebars 45 with different diameters.

When the steel bar (45) is to be removed, the person presses the pressing handle (a1), which causes the connecting ring (a33) with deformation force and the spring (a35) to assist the locking block (a34) in displacement, so that the locking block (a34) is released from the locking groove (416), and the moving body (413) moves a certain distance along the slide (417) and then moves to the inside of the side opening (414), thereby releasing the pressure on the steel bar (45) and facilitating the installation and removal of the steel bar (45). Step S3: Through the annular shape of the inner ring (q2) and its own tough deformation properties, as well as the setting of the support structure (q3), the support structure (q3) forms a uniform annular distribution at the distance between the outer ring (q1) and the inner ring (q2). The bonding block (q4) is subjected to the penetrating force of the steel bar (45), and transmits the pressure to the abutment block (q32). The swing rod (q31) swings with the force on the abutment block (q32). The spring steel (q33) assists in controlling the angle change between the swing rods (q31), so that the support structure (q3) can generate a flexible support force between the outer ring (q1) and the inner ring (q2), which facilitates the inner ring (q2) to cooperate with the tough bonding block (q4), and allows the diameter of the clamp (a36) to change flexibly, and allows for more flexible clamping installation of steel bars (45) with different diameters.
