Description

Technical Field

[0001] The utility model relates to the technical field of bridges, and more specifically, the utility model relates to a precast beam pedestal with adjustable longitudinal slope at the end Background Art

[0002] In bridge construction, precast assembled beams are widely used. To adapt to various geographical environments and meet the needs of different bridge uses, precast slab bridges with various different spans and structural forms are often used. The precast beam pedestal is the main temporary component for producing precast beams and is mainly used to bear the tension of prestressing. During the curing period of the beam body concrete, the strong tension of the tendons continuously acts on the precast beam pedestal. Therefore, the precast beam pedestal must be set with sufficient strength and stability

[0003] The adjustment of the longitudinal slope of the precast beam is to ensure the force balance on the longitudinal axis of the bridge bearing, prevent tilting, and is also beneficial for drainage and meeting the requirements of the navigable clearance under the bridge

[0004] At present, the precast beam pedestal generally adopts a combined structure of a steel panel and a concrete foundation. When adjusting the longitudinal slope, a hinge type slope adjuster for precast beams is used, which is achieved by adjusting a rotatable adjusting plate. However, the area of the adjusting plate is small, and the support for the precast beam is unstable Summary of the Utility Model

[0005] The precast beam pedestal with adjustable longitudinal slope at the end provided by the utility model aims to solve the problem that the hinge type slope adjuster for precast beams adjusts the longitudinal slope by rotating the adjusting plate, and the area of the adjusting plate is small, resulting in unstable support for the precast beam

[0006] To achieve the above object, the utility model provides the following technical solution: A precast beam pedestal with adjustable longitudinal slope at the end, comprising a pedestal base. The upper surface of the middle part of the pedestal base is fixedly installed with a panel. Both ends of the pedestal base have steps, and the surface of the steps is fixedly installed with a bottom plate. A beam slab is arranged above the steps, and the end of the beam slab is in contact and fit with the end of the panel. A plurality of bolts are arranged between the bottom plate and the beam slab. All the plurality of bolts are fixedly connected with the bottom plate, and nuts one are threadedly connected to all the plurality of bolts, and the nuts one support the lower surface of the beam slab

[0007] In a preferred embodiment, a support member is fixedly connected to the bottom of the beam slab. The support member is arranged at one end of the beam slab close to the panel. An arc-shaped plate is fixedly connected to the side wall of the step close to the panel end. The bottom of the support member is slidably connected to the inner surface of the arc-shaped plate

[0008] In a preferred embodiment, a side line is provided at the upper edge of the beam slab at one end close to the panel. The axis of the arc-shaped plate coincides with the side line, so that when the support member slides on the surface of the arc-shaped plate, the side line remains in contact with the edge of the panel

[0009] In a preferred embodiment, an inclined surface is provided at the lower side of the beam-slab near one end of the panel. A base is fixedly connected to the upper surface of the bottom plate. A filling plate is arranged inside the base. The filling plate is located at a position below the inclined surface. The filling plate is vertically slidably arranged inside the base. A pull rod assembly is arranged on one side of the base, and the pull rod assembly is used to drive the filling plate to move vertically.

[0010] In a preferred embodiment, the pull rod assembly includes a driving rod, a first ball head rod and a second ball head rod. A straight groove is provided on one side of the base. An inclined groove is provided on the side wall of the filling plate. One end of the driving rod is inserted into both the straight groove and the inclined groove and can slide inside the straight groove and the inclined groove. One end of the ball head of the first ball head rod is rotatably connected to the side wall of the driving rod. One end of the ball head of the second ball head rod is rotatably connected to the end of the support member. The ends of the first ball head rod and the second ball head rod close to each other are connected by a connecting member.

[0011] In a preferred embodiment, the connecting member is a second nut. A sliding groove is provided on the second ball head rod. One end of the first ball head rod is inserted into the second ball head rod. A sliding block is fixedly connected to the side wall of one end of the first ball head rod. The sliding block slides inside the sliding groove and extends to the outside of the sliding groove. The second nut is threadedly connected to the second ball head rod, so that the sliding block is pressed against the end of the sliding groove by the second nut.

[0012] In a preferred embodiment, the connecting member is a pin shaft. The first ball head rod and the second ball head rod are movably inserted into each other, and through holes are provided on the side walls of both the first ball head rod and the second ball head rod. The pin shaft is inserted into the through holes on the side walls of both the first ball head rod and the second ball head rod at the same time.

[0013] In a preferred embodiment, the distance between one end of the ball head of the second ball head rod and the end of the base of the corresponding pedestal is less than the distance between one end of the ball head of the first ball head rod and the end of the base of the corresponding pedestal.

[0014] In a preferred embodiment, one side of the upper end of the filling plate is a plane, and the other side is an arc surface. The plane fits the surface of the end of the panel, and the arc surface fits the surface of the inclined surface.

[0015] In a preferred embodiment, ten groups of bolts and first nuts are provided at each end of the pedestal base. The bottom of the bolt is fixedly welded to the upper surface of the bottom plate.

[0016] The technical effects and advantages of the present utility model:

[0017] By providing a support member and an arc plate and making the axis of the arc plate coincide with the side line, when adjusting the longitudinal slope of the beam-slab, the beam-slab swings with the side line as the axis, so that the position of the side line always remains unchanged, and thus the beam-slab will not be staggered downward with the panel to form small steps during adjustment.

[0018] With the provision of the filling plate, base and tie rod assembly in the present utility model, during the adjustment of the longitudinal slope of the beam slab, the space between the inclined plane and the end of the panel gradually increases. The support member can drive the filling plate to move upward through the tie rod assembly, enabling the upper end of the filling plate to fill the increased space, ensuring that the upper end of the filling plate can always support the inclined plane, and thus guaranteeing the stability of the beam slab after adjustment.

[0019] With the provision of the connecting component in the present utility model, when adjusting the longitudinal slope of the beam slab upward, the first ball head rod and the second ball head rod maintain a fixed length. Therefore, during the adjustment process, the filling plate can also be driven to move upward through the tie rod assembly to increase the support points of the beam slab and improve the stability. When adjusting the beam slab downward, the first ball head rod and the second ball head rod can be in an axially movable state, so that the filling plate can be moved downward first, and then the beam slab can be adjusted downward, preventing the beam slab from being affected by the filling plate.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to the attached drawings of the specification Figures 1 - 10 A precast beam pedestal with an adjustable longitudinal slope at the end includes a pedestal base 1. A panel 11 is fixedly installed on the upper surface of the middle part of the pedestal base 1. Both ends of the pedestal base 1 have steps 10. A bottom plate 2 is fixedly installed on the surface of the steps 10. A beam-slab 3 is arranged above the steps 10. The end of the beam-slab 3 is in contact and fit with the end of the panel 11. A plurality of bolts 4 are arranged between the bottom plate 2 and the beam-slab 3. All the plurality of bolts 4 are fixedly connected to the bottom plate 2. A first nut 41 is threadedly connected to each of the plurality of bolts 4. The first nut 41 supports on the lower surface of the beam-slab 3.

[0033] It should be noted that the pedestal base 1 is formed by concrete casting. The panel 11, the bottom plate 2 and the beam-slab 3 are all steel plates. The bottom of the bolt 4 is fixedly welded to the upper surface of the bottom plate 2. Multiple groups of bolts 4 and first nuts 41 are arranged at each end of the pedestal base 1, such as eight groups, ten groups, etc. As Figure 2 shown, ten groups of bolts 4 and first nuts 41 are arranged.

[0034] In this embodiment, the implementation manner is specifically as follows: As Figure 1 shown, before precasting a precast slab bridge, it is necessary to adjust the longitudinal slope of the precast beam pedestal, that is, to adjust the inclination angle of the beam-slab 3. Specifically, when adjusting, use a wrench to rotate the first nut 41 upward. Taking Figure 1 the left part as an example, first rotate the left first nut 41, and then sequentially rotate the right first nut 41 as needed. The height at which the left first nut 41 jacks up the beam-slab 3 is higher than the height at which the right first nut 41 jacks up the beam-slab 3, so as to achieve the purpose of adjusting the longitudinal slope.

[0035] In the above technical solution, by setting up multiple groups of bolts 4 and nuts 41, the nuts 41 are turned to make the nuts 41 push the beam 3 upward so that the beam 3 is tilted, thereby achieving the purpose of adjusting the longitudinal slope. Compared with the existing prefabricated beam hinged slope adjuster, since the entire beam 3 will be tilted when the longitudinal slope is adjusted, its supporting surface is large and it is more stable when supporting the prefabricated beam.

[0036] Refer to the instruction manual Figures 3 - 7 and Figure 10 When adjusting the longitudinal slope of the beam slab 3, since the height of the nut 41 cannot be accurately controlled, the following may occur: Figure 10 As shown in the left figure, during adjustment, due to gravity, the end of the beam 3 is offset downward from the panel 11, forming a small step, causing the problem of inaccurate adjustment.

[0037] In this regard, a support member 5 is fixedly connected to the bottom of the beam 3, and the support member 5 is arranged at one end of the beam 3 close to the panel 11. An arc plate 51 is fixedly connected to the side wall of the step 10 close to the panel 11, and the bottom of the support member 5 is slidably connected to the inner surface of the arc plate 51.

[0038] Furthermore, the upper edge of the beam plate 3 near one end of the panel 11 has a side line 30 , and the axis of the arc plate 51 coincides with the side line 30 , so that when the support member 5 slides on the surface of the arc plate 51 , the side line 30 remains in contact with the edge of the panel 11 .

[0039] It should be noted that a connecting block is fixed to the bottom of the support member 5, and an arc groove is provided on the inner surface of the arc plate 51, and the support member 5 slides in the arc groove through the connecting block. Figure 7 As shown, when adjusting the longitudinal slope of the beam 3, the right end of the beam 3 swings upward. During the swinging process, the support member 5 slides upward on the inner surface of the arc plate 51. Since the axis of the arc plate 51 is the edge line 30, the beam 3 swings upward with the edge line 30 as the axis. That is to say, in the swinging position of the beam 3, the position of the edge line 30 remains unchanged and always conflicts with the upper edge of the upper end of the panel 11, as shown in FIG. Figure 10 As shown in the right figure.

[0040] The above technical solution is achieved by setting a support member 5 and an arc plate 51, and making the axis of the arc plate 51 coincide with the edge line 30, so that when the longitudinal slope of the beam slab 3 is adjusted, the beam slab 3 swings around the edge line 30, so that the position of the edge line 30 always remains unchanged, and the beam slab 3 will not be offset downward from the panel 11 to form a small step when adjusted.

[0041] Refer to the instruction manual Figures 3 - 10, when the beam-slab 3 is adjusted upward, a gap will be formed between one end of the beam-slab 3 close to the panel 11 and the end of the panel 11, and this gap will reduce the stability of the beam-slab 3. To improve the stability of the beam-slab 3, specifically, an inclined surface 31 is provided at the lower side position of one end of the beam-slab 3 close to the panel 11, a base 7 is fixedly connected to the upper surface of the bottom plate 2, a filling plate 6 is arranged inside the base 7, the filling plate 6 is located at the position below the inclined surface 31, the filling plate 6 is vertically slidably arranged inside the base 7, and a pull rod assembly 8 is arranged on one side of the base 7, and the pull rod assembly 8 is used to drive the filling plate 6 to move vertically.

[0042] Furthermore, the pull rod assembly 8 includes a driving rod 81, a first ball head rod 82 and a second ball head rod 83. A straight groove 71 is provided on one side of the base 7, and an inclined groove 60 is provided on the side wall of the filling plate 6. One end of the driving rod 81 is inserted into both the straight groove 71 and the inclined groove 60 and can slide inside the straight groove 71 and the inclined groove 60. One end of the ball head of the first ball head rod 82 is rotatably connected to the side wall of the driving rod 81. One end of the ball head of the second ball head rod 83 is rotatably connected to the end of the support member 5. The ends of the first ball head rod 82 and the second ball head rod 83 close to each other are connected by a connecting member.

[0043] It should be noted that as Figure 6 shown is the state when the beam-slab 3 is not adjusted. At this time, the upper end of the filling plate 6 abuts against the position between the inclined surface 31 and the end of the panel 11. When the beam-slab 3 is adjusted upward, the pull rod assembly 8 is used to drive the filling plate 6 to move upward to support the inclined surface 31, increasing the support points of the inclined surface 31, thereby improving the stability of the beam-slab 3. Specifically, when the beam-slab 3 is adjusted upward, in Figure 6 the direction, the support member 5 will move right-upper. At this time, the support member 5 can pull the driving rod 81 to move through the second ball head rod 83 and the driving rod 81. The moving direction of the driving rod 81 is to the right in Figure 4 the direction. The driving rod 81 moves inside both the straight groove 71 and the plane 61 at the same time. The straight groove 71 is straight, so the base 7 remains stationary, while the inclined groove 60 is inclined. As Figure 5 shown, the right end of the inclined groove 60 faces downward and the left end faces upward. Therefore, when the driving rod 81 moves to the right, it will push the inner wall of the inclined groove 60, causing the filling plate 6 to move upward. That is to say, when the beam-slab 3 swings upward, the space between the inclined surface 31 and the end of the panel 11 gradually becomes larger, and during the swinging process, the filling plate 6 will slowly move upward to ensure that the upper end of the filling plate 6 can always support the inclined surface 31.

[0044] In the above technical solution, through the arrangement of the filling plate 6, the base 7 and the tie rod assembly 8, during the longitudinal slope adjustment of the beam slab 3, the space between the inclined surface 31 and the end of the panel 11 gradually becomes larger. The support member 5 can drive the filling plate 6 to move upward through the tie rod assembly 8, so that the upper end of the filling plate 6 fills the increased space, ensuring that the upper end of the filling plate 6 can always support the inclined surface 31, thereby ensuring the stability of the beam slab 3 after adjustment.

[0045] As Figure 4 , Figure 5 and Figure 8 shown, a specific structural form of the connecting component is provided here. Specifically, the connecting component is the second nut 100. A sliding groove 831 is formed on the spherical head rod two 83. One end of the spherical head rod one 82 is inserted into the inside of the spherical head rod two 83. A sliding block 821 is fixedly connected to the side wall of one end of the spherical head rod one 82. The sliding block 821 slides inside the sliding groove 831, and the sliding block 821 extends to the outside of the sliding groove 831. The second nut 100 is threadedly connected to the spherical head rod two 83, so that the sliding block 821 is pressed against the end of the sliding groove 831 through the second nut 100.

[0046] It should be noted that the sliding block 821 can slide inside the sliding groove 831 to increase the overall length of the spherical head rod one 82 and the spherical head rod two 83. When the second nut 100 is screwed, and the second nut 100 presses the sliding block 821 against the end of the sliding groove 831, the overall length of the spherical head rod one 82 and the spherical head rod two 83 will no longer change.

[0047] As Figure 9 shown, a specific structural form of the connecting component is also provided here. Specifically, the connecting component is the pin shaft 9. The spherical head rod one 82 and the spherical head rod two 83 are inserted into each other movably, and through holes 90 are formed on the side walls of the spherical head rod one 82 and the spherical head rod two 83. The pin shaft 9 is inserted into the through holes 90 on the side walls of the spherical head rod one 82 and the spherical head rod two 83 at the same time.

[0048] It should be noted that when the pin shaft 9 is removed from the through hole 90, the spherical head rod one 82 and the spherical head rod two 83 can move relative to each other, so that the overall length of the spherical head rod one 82 and the spherical head rod two 83 is variable. When the pin shaft 9 is inserted into the through holes 90 on the spherical head rod one 82 and the spherical head rod two 83, the overall length of the spherical head rod one 82 and the spherical head rod two 83 will no longer change.

[0049] Both of the above two connecting components can keep the lengths of the first ball head rod 82 and the second ball head rod 83 at a fixed length, and can also enable the first ball head rod 82 and the second ball head rod 83 to move axially. The purpose is that when it is necessary to adjust the beam plate 3 downward, the end of the beam plate 3 may press the upper end of the filling plate 6 against the panel 11, making it difficult for the filling plate 6 to move, and thus making it difficult for the beam plate 3 to swing downward. Therefore, when it is necessary to adjust the beam plate 3 upward, first make the first ball head rod 82 and the second ball head rod 83 in a state where they can move axially, and then pull the first ball head rod 82 to drive the driving rod 81 to first drive the filling plate 6 to move downward, and then the beam plate 3 can be smoothly adjusted downward without being affected.

[0050] Through the setting of the connecting component in the above technical solution, when adjusting the longitudinal slope of the beam plate 3 upward, the first ball head rod 82 and the second ball head rod 83 are kept at a fixed length. Thus, during the adjustment process, the filling plate 6 can also be driven to move upward by the pull rod assembly 8 to increase the support points of the beam plate 3 and improve stability. When adjusting the beam plate 3 downward, the first ball head rod 82 and the second ball head rod 83 can be made in a state where they can move axially, so that the filling plate 6 can be moved downward first, and then the beam plate 3 can be adjusted downward without being affected by the filling plate 6.

[0051] Further, the distance between the ball head end of the second ball head rod 83 and the end of the corresponding pedestal base 1 is less than the distance between the ball head end of the first ball head rod 82 and the end of the corresponding pedestal base 1.

[0052] It should be noted that, taking Figure 6 as an example, the above technical solution means that the distance between the second ball head rod 83 and the right end of the beam plate 3 is less than the distance between the first ball head rod 82 and the right end of the beam plate 3, so as to facilitate the support member 5 to drive the filling plate 6 to move through the pull rod assembly 8.

[0053] Further, one side of the upper end of the filling plate 6 is a flat surface 61, and the other side is an arc surface 62. The flat surface 61 fits the surface of the end of the panel 11, and the arc surface 62 fits the surface of the inclined surface 31.

[0054] It should be noted that the side wall of the end of the panel 11 remains stationary. Therefore, the flat surface 61 is used to fit it. When the beam plate 3 is adjusted upward, the angle between the inclined surface 31 and the panel 11 becomes larger. Therefore, the filling plate 6 moves upward, and the arc surface 62 is used to fit the inclined surface 31.

[0055] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
