Description

Technical Field

[0001] The utility model relates to the technical field of installation of wedge-shaped anti-falling beams, in particular to a pier top embedded component for installation of wedge-shaped anti-falling beams. Background Art

[0002] An anti-fall beam is an earthquake-resistant structural measure used in bridge construction. Its primary purpose is to prevent the beam from falling off the pier during disasters such as earthquakes, thereby ensuring the safety and stability of the bridge structure. As an important type of anti-fall beam, the tenon-shaped anti-fall beam requires one end to be fixed to the top of the pier during installation, while the other end is embedded in the bottom of the beam. The non-embedded steel cylinder installed at the pier top is first placed in the reserved hole at the pier top. After alignment with the extended steel cylinder embedded in the bottom of the beam and installation is complete, the reserved hole at the pier top is densely filled with grouting material and cured, thereby securing the non-embedded steel cylinder to the pier top.

[0003] The reserved holes on the pier top are generally formed before the pier is cast. A positioning frame is set at the position of the non-embedded steel cylinder of the wedge-shaped anti-fall beam on the pier top, and the positioning frame is used to position the embedded parts at the embedded position of the pier top. The embedded parts are removed after the pier has initially set. A barrel with an oblong cross-section is often used as the embedded part, and the positioning and installation are achieved by abutting against the positioning frame. The positioning of the barrel is not stable enough. When the pier is cast, the concrete slurry can easily cause the barrel to shift, resulting in poor final forming quality of the reserved hole, which affects the installation of the non-embedded steel cylinder of the wedge-shaped anti-fall beam.

[0004] To this end, the present application specifically proposes a pier top embedded component for installing a wedge-shaped anti-fall beam to solve the above technical problems. Utility Model Content

[0005] The main purpose of the utility model is to solve the above-mentioned deficiencies and provide a pier top embedded component for installing a wedge-shaped anti-fall beam, which is firmly installed and can avoid deviation during the pouring of the pier.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A pier top embedded component for installing a wedge-shaped anti-fall beam is inserted into a positioning frame on the pier top, comprising: a barrel body, the cross-section of the barrel body is oblong, the bottom is sealed and the top is open, and the bottom sealed end serves as an end inserted into the pier top; a mounting frame, symmetrically arranged on both sides of the outer wall of the barrel body that is not inserted into the pier top; a snap-fit plate, slidably arranged on the mounting frame, for snapping into the positioning frame; a locking piece, fixedly arranged on the mounting frame, for driving the snap-fit plate to slide on the mounting frame, so that it is pressed against or loosened from the positioning frame.

[0008] Furthermore, the cross-section of the snap-fit plate is L-shaped, including a bottom plate and a side plate. A limiting column is fixedly provided on the top of the side plate. A long limiting groove is provided on the mounting frame for the limiting column to pass through. A stop block is fixedly provided on one end of the limiting column passing through the limiting groove.

[0009] Furthermore, the locking member includes a stud threadedly connected and passing through the mounting frame and a handwheel fixedly arranged on the end of the stud extending out of the mounting frame, and the end of the stud extending into the mounting frame is rotatably connected to the side plate.

[0010] Furthermore, the inner cavity of the barrel body inserted into the pier top part is provided with a plurality of inner supports, and the inner supports include a first reinforcement ring fixedly provided in the inner cavity of the barrel body and in contact with the inner cavity, and a support rod assembly fixedly provided on the inner wall of the first reinforcement ring.

[0011] Furthermore, the plurality of inner support members are parallel to the bottom surface of the barrel body and the distance between adjacent inner support members gradually increases from bottom to top.

[0012] Furthermore, a lifting assembly is fixedly arranged in the inner cavity of the top of the barrel body, and the lifting assembly includes a second reinforcement ring fixedly arranged in the inner cavity of the barrel body and a lifting rod fixedly arranged on the second reinforcement ring. The lifting assembly is located above the inner support member.

[0013] The beneficial effects of the present invention are as follows:

[0014] The utility model provides mounting frames on both sides of the barrel body, and provides slidable buckling plates and locking members for driving the buckling plates to slide on the mounting frames. The buckling plates are driven to slide on the mounting frames by the locking members until the buckling plates buckle the crossbeams of the positioning frame and press against each other. At this time, the barrel body is fixed on the positioning frame and is not prone to deflection and displacement.

[0015] By setting the cross-section of the snap-fit plate to be L-shaped and divided into a bottom plate and side plates, the side plates of the two snap-fit plates clamp the positioning frame to fix the barrel body. While the side plates clamp the positioning frame, the bottom plate is located below the ground of the positioning frame. Once the buoyancy of the barrel body caused by the concrete slurry is greater than the friction between the side plates and the positioning frame, the barrel body floats up and the bottom plate abuts against the ground of the positioning frame to prevent the barrel body from floating up further, thereby improving the stability of the barrel body fixation.

[0016] By setting an internal support component consisting of a first reinforcement ring and a support rod assembly in the inner cavity of the barrel body inserted into the pier top part, when the barrel body is squeezed by concrete slurry, the support rod assembly applies the supporting force more evenly on the inner wall of the barrel body through the first reinforcement ring to resist the pressure on the barrel body and prevent the barrel body from deformation.

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] like Figure 1-7 As shown, the utility model provides a pier top embedded component for installing a wedge-shaped anti-fall beam, which is inserted into a positioning frame 4 on the pier top, including:

[0028] The barrel body 1 has an oblong cross section, a sealed bottom and an open top, and the sealed bottom end serves as an end for inserting into the pier top;

[0029] The mounting brackets 2 are symmetrically arranged on both sides of the outer wall of the barrel body 1 which is not inserted into the pier top;

[0030] The buckle plate 3 is slidably arranged on the mounting frame 2 and is used for buckling the positioning frame 4;

[0031] The locking member 5 is fixedly mounted on the mounting frame 2 and is used to drive the snap-fit plate 3 to slide on the mounting frame 2 so as to press against or release from the positioning frame 4 .

[0032] When in use, first use the locking piece 5 to drive the snapping plate 3 to slide on the mounting frame 2 and away from the barrel body 1, then place the barrel body 1 into the specified position in the positioning frame 4, so that the mounting frame 2 abuts the top surface of the positioning frame 4, and then use the locking piece 5 again to drive the snapping plate 3 to slide on the mounting frame 2 until the snapping plate 3 buckles the crossbeam of the positioning frame 4 and presses against each other. At this time, the barrel body 1 is fixed on the positioning frame 4 and is not prone to deflection and displacement.

[0033] In one embodiment, the engaging plate 3 has an L-shaped cross-section and comprises a base plate 31 and side plates 32. A limit post 6 is fixedly mounted on the top of the side plate 32. The mounting frame 2 is provided with an elongated limit slot 7 for the limit post 6 to pass through. A stopper 8 is fixedly mounted on one end of the limit post 6 that passes through the limit slot 7. The locking member 5 comprises a stud 51 threadedly connected to the mounting frame 2 and a handwheel 52 fixed to the end of the stud 51 that extends from the mounting frame 2. The end of the stud 51 that extends into the mounting frame 2 is rotatably connected to the side plate 32.

[0034] With this design, when the snap-fit plate 3 is pressed against the positioning frame 4, the bottom plate 31 is located on the ground of the positioning frame 4 but the two are not in contact, the side plates 32 are pressed against the sides of the positioning frame 4, and the two side plates 32 on both sides of the barrel body 1 jointly clamp the positioning frame 4 to fix the barrel body 1. When pouring bridge piers, the barrel body 1 immersed in the concrete slurry will be subjected to a vertical upward buoyancy, which makes the barrel body 1 tend to move upward. When the buoyancy is greater than the friction between the side plates 32 and the positioning frame 4, the barrel body 1 floats up, and the bottom plate 31 is pressed against the ground of the positioning frame 4, so that the barrel body 1 cannot continue to float up, thereby improving the stability of the barrel body 1.

[0035] By turning the handwheel 52, the stud 51 can be driven to rotate and screwed into the mounting frame 2, thereby driving the snap-fit plate 3 to gradually approach the barrel body 1 along the limiting groove 7 until the snap-fit plate 3 is pressed against the positioning frame 4 to fix the barrel body 1. When the handwheel 52 is turned in the opposite direction, the snap-fit plate 3 is loosened from the positioning frame 4.

[0036] In one embodiment, the inner cavity of the barrel body 1 inserted into the pier top part is provided with a plurality of internal support members 9, and the internal support members 9 include a first reinforcement ring 91 fixedly provided in the inner cavity of the barrel body 1 and in contact with the inner cavity, and a support rod assembly 92 fixedly provided on the inner wall of the first reinforcement ring 91.

[0037] Due to the existence of liquid pressure, the barrel body 1 immersed in the concrete slurry will be subjected to the pressure exerted by the concrete slurry on the barrel wall. If the pressure is too large, the barrel body 1 will be deformed, affecting the molding effect of the reserved hole. With this design, when the barrel body 1 is squeezed, the support rod assembly 92 applies the supporting force more evenly to the inner wall of the barrel body 1 through the first reinforcement ring 91 to counteract the pressure exerted on the barrel body 1 and prevent the barrel body 1 from deforming.

[0038] In one embodiment, the plurality of inner support members 9 are parallel to the bottom surface of the barrel body 1 and the distance between adjacent inner support members 9 increases gradually from bottom to top.

[0039] The smaller the spacing between the inner support members 9, the stronger the ability of the barrel body 1 to resist external pressure, and the larger the spacing between the inner support members 9, the weaker the ability of the barrel body 1 to resist external pressure. Since the pressure exerted by the concrete slurry on the barrel body 1 from bottom to top gradually decreases, the spacing between adjacent inner support members 9 can be gradually increased from bottom to top while ensuring that the barrel body 1 will not be deformed by pressure, thereby reducing the number of inner support members 9 used and reducing manufacturing costs.

[0040] In one embodiment, a lifting assembly 10 is fixedly installed in the inner cavity at the top of the barrel body 1. The lifting assembly 10 includes a second reinforcement ring 101 fixedly installed in the inner cavity of the barrel body 1 and a lifting rod 102 fixedly installed on the second reinforcement ring 101. The lifting assembly 10 is located above the inner support member 9.

[0041] With this design, when the barrel body 1 is placed in the positioning frame 4 and when the barrel body 1 is pulled out from the initially set bridge pier, it can be operated through the lifting rod 102, which is convenient for use. The function of the second reinforcement ring 101 here is similar to that of the first reinforcement ring 91, and is used to strengthen the structural stability of the barrel body 1 to prevent the barrel body 1 from being easily deformed when external force is applied to the lifting rod 102.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.

[0043] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0044] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, "multiple" refers to more than two.
