[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] At present, a pedestal is usually provided at the lower end of a precast beam. The traditional precast beam pedestal is made of concrete, which needs to be chiseled out after the beam slab is prefabricated.

[0036] However, in mountainous areas, rural roads are narrow and it is impossible to concentrate on prefabrication and transportation of concrete components to the site, so they can only be prefabricated on site. Due to the long construction period of on-site concrete pedestals, and the reserved prefabricated beam anti-arch value during the construction process, it is difficult to reach the theoretical parabolic curvature due to the fluidity of concrete. Once hardened and formed, if there is a problem, it will be chiseled out, making corrections very difficult.

[0037] Based on the above problems, the present application provides a prefabricated beam pedestal. Through the height-adjustable second support part 21 in the support seat 2, the height can be adjusted according to the actual casting conditions of the base 1 when the beam bottom panel 3 is placed therethrough, so as to ensure that the final prefabricated beam pedestal has the required anti-arch value. At the same time, the casting height requirement of the base 1 is reduced, so as to improve the casting efficiency of the base 1, and solve the technical problems in the related technology that the on-site cast base 1 cannot be accurately cast and the casting height is difficult to correct when there is a problem.

[0038] Reference Figure 1 , a prefabricated beam pedestal is provided for the embodiment of the present application, which includes:

[0039] The base 1 is extended along the length direction of the prefabricated beam;

[0040] The support base 2 includes a first support portion 20 and a second support portion 21, wherein the first support portion 20 is fixedly disposed on the base 1, and the second support portion 21 is disposed on the top surface of the first support portion 20 and is movably arranged with adjustable height;

[0041] A beam bottom panel 3, which is laid on the upper surface of the second supporting portion 21;

[0042] The connecting assembly 4 includes a first connecting plate 41 fixedly arranged on the first supporting portion 20 and a second connecting plate 42 arranged on the beam bottom panel 3. The first connecting plate 41 and / or the second connecting plate 42 are provided with multiple connecting points in the vertical direction so that the two can be connected at different connecting points.

[0043] Specifically, the base 1 in this embodiment is a concrete base 1 cast on site. Due to the arrangement of the support base 2 above it, the base 1 does not need to bear the task of directly supporting the bottom panel 3 of the beam. The bottom panel 3 of the beam will be supported by the support base 2. At the same time, due to the overall height adjustability of the support base 2, the height of the support base 2 can be adjusted according to the casting height and the required arch degree to ensure that the support base 2 and the base 1 finally have a suitable arch degree. For the base 1, the casting requirements and difficulty are greatly reduced.

[0044] The first support portion 20 in the support seat 2 is specifically an I-beam longitudinal beam fixedly mounted on the base 1 in this embodiment, and the two side plates of the I-beam longitudinal beam are placed horizontally, and the second support portion 21 is arranged on the top surface of the I-beam longitudinal beam.

[0045] The second support portion 21 in the support seat 2 is specifically a plurality of support plates 210 stacked on the first support portion 20 in this embodiment. The support plates 210 are preferably steel plate structures, so that the height of the second support portion 21 can be adjusted according to the number of support plates 210. Therefore, the specific number of the second support portion 21 is obtained according to the anti-arch value, the height of the base 1 and the first support portion 20.

[0046] In addition, for the bottom panel 3 used to support the prefabricated beam, when it is placed on the second support part 21 of the support seat 2, it is not connected to the second support part 21, but is fixedly connected to the first support part 20 that has been fixed in the support seat 2 through the first connecting plate 41 and the second connecting plate 42. Compared with the height-adjustable second support part 21, the first support part 20 is more stable, thereby effectively reducing the instability factor of the bottom panel 3 when it is connected to the movable second support part 21, so that the overall prefabricated beam pedestal has higher stability, and when the bottom panel 3 is fixedly connected to the first support part 20, different connection points can be used to achieve fixed connection at different heights.

[0047] Furthermore, in some embodiments, the first connecting plate 41 and the second connecting plate 42 both extend vertically, and one of the first connecting plate 41 and the second connecting plate 42 is provided with a waist-shaped connecting hole 43 extending vertically, and the other is provided with a mounting hole 44 corresponding to the waist-shaped connecting hole 43, and the mounting hole 44 is aligned with the waist-shaped connecting hole 43 at different heights to form a plurality of different connecting points;

[0048] The connecting assembly 4 further includes a connecting bolt 45 , which penetrates the waist-shaped connecting hole 43 and the mounting hole 44 and fixes the first connecting plate 41 and the second connecting plate 42 .

[0049] Specifically, in this embodiment, the first connecting plate 41 is fixedly welded to the edge of the top of the I-beam longitudinal beam as the first support portion 20, and is vertically arranged, and the waist-shaped connecting hole 43 is opened on the first connecting plate 41. The second connecting plate 42 is vertically fixedly welded to the bottom surface of the beam bottom panel 3, and is parallel to the first connecting plate 41, and the mounting hole 44 is opened thereon. When the beam bottom panel 3 is placed on the first support portion 20, it is necessary to control the beam bottom panel 3 to move to a certain height alignment of the mounting hole 44 and the waist-shaped connecting hole 43, at which time the two can be fixedly connected by the connecting bolt 45. At the same time, due to the use of the waist-shaped connecting hole 43, a plurality of connection points for the connecting bolt 45 to pass through are formed in the extension direction of the waist-shaped connecting hole 43, ensuring that the connecting bolt 45 can be connected conveniently and quickly. In addition, the detachable connection is achieved by the connecting bolt 45, so that the beam bottom panel 3 can be quickly disassembled and reused after the prefabricated beam is completed.

[0050] Furthermore, in some embodiments, a plurality of the support seats 2 are spaced apart in the width direction of the precast beam, and the second support portions 21 on the plurality of support seats 2 are of the same height.

[0051] In the embodiment in which a plurality of support seats 2 are provided in the width direction of the precast beam, a first connecting plate 41 is provided on one side of another adjacent support seat 2 of the support seat 2, and two second connecting plates 42 are provided on the bottom panel 3 of the beam corresponding to the two first connecting plates 41 within the interval, and the first connecting plate 41 and the second connecting plate 42 are both parallel to the length direction of the precast beam, so that the bottom panel 3 of the beam above the plurality of support seats 2 can be limited by the two first connecting plates 41 in the width direction.

[0052] Specifically, by arranging a plurality of support seats 2 in the width direction of the precast beam, it is possible to reasonably share the weight of the precast beam in the width direction while avoiding the support seats 2 being too wide in this direction, which would cause certain difficulties in selecting the structure of the support seats 2 itself.

[0053] Furthermore, in some embodiments, a plurality of support seats 2 are provided at intervals in the extension direction of the precast beam.

[0054] Specifically, in order to prevent the support seat 2 from extending too long under the prefabricated beam, which would cause greater difficulties in materials and installation, the present application also effectively solves this problem by providing a plurality of spaced support seats 2 in the extension direction of the prefabricated beam.

[0055] Furthermore, in some embodiments, the beam bottom panel 3 includes:

[0056] A plurality of first panels 30 are placed correspondingly on each of the support seats 2, and the first panels 30 are provided with docking plates 32 at both ends in the length direction of the precast beam, wherein the docking plate 32 at one end is provided with a waist hole 33 extending vertically, and the docking plate 32 at the other end is provided with a docking hole, and the two ends of adjacent first panels 30 are bolted and fixed through the waist hole 33 and the docking hole.

[0057] By such arrangement, the bottom panel 3 of the beam is composed of a plurality of first panels 30 connected together, and adjacent first panels 30 can be bolted and fixed with relative height adjustment through the waist holes 33 and the docking holes. Furthermore, adjacent support seats 2 can still be fixedly connected when the heights are different, thereby ensuring the integrity of the bottom panel 3 of the beam.

[0058] Furthermore, in some embodiments, the beam bottom panel 3 further includes:

[0059] Two second panels 31 are arranged between adjacent first panels 30 and the two second panels 31 are respectively arranged at the two ends of the beam bottom panel 3, and the two ends of the second panel 31 are connected to the docking plate 32, and the waist hole 33 and the docking hole are respectively opened on the docking plates 32 at both ends, and the length of the second panel 31 is less than the interval between the two support seats 2.

[0060] Specifically, in order to support and lift the precast beam placed on the beam bottom panel 3, the present embodiment further provides a second panel 31 at both end areas of the beam bottom panel 3. The second panel 31 is located between the two support seats 2, and its two ends are detachably bolted to the first panels 30 on both sides through the waist holes 33 and the docking holes on the docking plate 32. And because the length of the second panel 31 is less than the interval between the two support seats 2, when it is necessary to support and lift the precast beam on the beam bottom panel 3, the bolting of the first panel 30 on the side of the second panel 31 can be directly released. At this time, because the second panel 31 is in a suspended state, the second panel 31 can be directly transferred from the bottom of the precast beam, and finally a lifting gap that can directly lift the precast beam is formed between the two support seats 2, so that the relevant lifting ropes can support and lift the precast beam upward.

[0061] Furthermore, in some embodiments, the support seat 2 is detachably connected to the base 1. Specifically, the I-beam longitudinal beam constituting the first support portion 20 at the bottom of the support seat 2 is detachably connected to the base 1 below by embedded bolts 200.

[0062] This arrangement can further improve the assembly and disassembly characteristics of the precast beam pedestal. After the construction of the precast beam is completed, the support seat 2 and the beam bottom panel 3 can be disassembled and split, so that during the construction process of the precast beam pedestal, most of the structure except the base 1 made of concrete can be reused.

[0063] Furthermore, in some embodiments, the beam bottom panel 3 has grout-stopping grooves 34 on both sides of the extension direction of the precast beam, the length direction of the grout-stopping grooves 34 is parallel to the length direction of the precast beam, and a grout-stopping rod 35 is installed inside the grout-stopping grooves 34 .

[0064] Furthermore, in some embodiments, a magnetic sheet 36 is attached to the surface of the stop rod 35 so that the stop rod 35 can be stably installed in the stop groove 34, thereby ensuring that the stop rod 35 has good stability.
