Description

Technical Field

[0001] This invention relates to the field of precast beam construction, and specifically to a precast beam support. Background Technology

[0002] Currently, precast beams are usually provided with a platform at the bottom. Traditional precast beam platforms are made of concrete, which need to be removed after the beam is precast.

[0003] However, in mountainous areas, the roads are narrow, making it impossible to centrally prefabricate concrete components at the factory and transport them to the site. Instead, prefabrication must be done on-site. Because on-site fabrication of concrete platforms has a long construction period, and the pre-reserved camber value for the precast beams during construction is difficult to achieve the theoretical parabolic arc due to the fluidity of the concrete, once hardened and formed, any problems will require chiseling away, making corrections extremely difficult. Summary of the Invention

[0004] This application provides a precast beam abutment that can solve the technical problem in related technologies where it is difficult to correct the camber value of precast beam abutments cast on-site during on-site construction.

[0005] A precast beam platform, characterized in that it comprises:

[0006] The base extends along the length of the precast beam;

[0007] The support base includes a first support part and a second support part. The first support part is fixedly disposed on the base, and the second support part is disposed on the top surface of the first support part and is movable with adjustable height.

[0008] The bottom panel of the beam is laid on the upper surface of the second support part;

[0009] The connecting assembly includes a first connecting plate fixedly disposed on the first support and a second connecting plate disposed on the bottom panel of the beam. The first connecting plate and / or the second connecting plate are provided with multiple connection points in the vertical direction so that the two can be connected at different connection points.

[0010] In one embodiment, both the first connecting plate and the second connecting plate extend vertically, and one of the first connecting plate and the second connecting plate is provided with a waist-shaped connecting hole extending vertically, and the other is provided with a mounting hole for corresponding to the waist-shaped connecting hole, and multiple different connection points are formed by aligning the mounting hole and the waist-shaped connecting hole at different heights.

[0011] The connecting assembly further includes a connecting bolt, which passes through the waist-shaped connecting hole and the mounting hole and fixes the first connecting plate and the second connecting plate.

[0012] In one embodiment, the second support portion includes:

[0013] Multiple support plates are stacked on the first support part, and the specific number of them is determined according to the anti-arch value, the height of the base and the first support part.

[0014] In one embodiment, multiple support seats are spaced apart in the width direction of the precast beam, and the second support portion on the multiple support seats has the same height.

[0015] In one embodiment, the support bases are provided at intervals along the extension direction of the precast beam.

[0016] In one embodiment, the bottom panel of the beam includes:

[0017] Multiple first panels are placed on each of the support seats, and each first panel has a butt plate at both ends in the length direction of the precast beam. One end of the butt plate has a waist hole extending vertically, and the other end of the butt plate has a butt hole. The two ends of adjacent first panels are bolted together and fixed through the waist hole and the butt hole.

[0018] In one embodiment, the bottom panel of the beam further includes:

[0019] Two second panels are disposed between adjacent first panels and are respectively disposed at both ends of the bottom panel of the beam. Both ends of the second panels are connected to the butt plate. The butt plate at both ends is respectively provided with the waist hole and the butt hole. The length of the second panel is less than the interval between the two support seats.

[0020] In one embodiment, the support base is detachably connected to the base.

[0021] In one embodiment, the bottom panel of the beam has grout-stopping grooves on both sides of the precast beam extending in the direction of extension. The length direction of the grout-stopping grooves is parallel to the length direction of the precast beam, and grout-stopping rods are installed inside the grout-stopping grooves.

[0022] In one embodiment, a magnetic sheet is attached to the surface of the anti-slurry rod.

[0023] The beneficial effects of the technical solutions provided in this application include:

[0024] By using a height-adjustable second support within the support base, the height can be adjusted according to the actual pouring conditions of the foundation when placing the bottom panel of the beam. This ensures that the final precast beam platform has the required anti-camber value. At the same time, it reduces the pouring height requirement of the foundation, thereby improving the pouring efficiency of the foundation. This solves the technical problems in related technologies where it is difficult to accurately pour the foundation on-site and where it is difficult to correct problems when there are issues with the pouring height.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0035] Currently, precast beams are usually provided with a platform at the bottom. Traditional precast beam platforms are made of concrete, which need to be removed after the beam is precast.

[0036] However, in mountainous areas, rural roads are narrow, making it impossible to centrally prefabricate concrete components at factories and transport them to the site. Instead, prefabrication must be done on-site. Because on-site fabrication of concrete platforms has a long construction period, and the pre-reserved camber value for the precast beams during construction is difficult to achieve the theoretical parabolic arc due to the fluidity of concrete, once hardened and formed, any problems will require chiseling away, making corrections extremely difficult.

[0037] Based on the above problems, this application provides a precast beam platform. Through the height-adjustable second support part 21 inside the support base 2, the height can be adjusted according to the actual pouring situation of the base 1 when the bottom panel 3 of the beam is placed through it, so as to ensure that the final precast beam platform has the required anti-camber value. At the same time, it reduces the pouring height requirement of the base 1, thereby improving the pouring efficiency of the base 1. It solves the technical problems in the related technology that it is difficult to accurately pour the base 1 on site and that it is difficult to correct the problem when there is a problem with the pouring height.

[0038] Reference Figure 1 This application provides a precast beam support, which includes:

[0039] Base 1 is provided extending along the length of the precast beam;

[0040] The support base 2 includes a first support part 20 and a second support part 21. The first support part 20 is fixedly disposed on the base 1, and the second support part 21 is disposed on the top surface of the first support part 20 and is movable with adjustable height.

[0041] The bottom panel 3 of the beam is laid on the upper surface of the second support 21;

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

[0043] Specifically, in this embodiment, the base 1 is a concrete base 1 cast on site. Due to the setting of the support seat 2 above it, the base 1 does not need to bear the task of directly supporting the bottom panel 3 of the beam. The support seat 2 will bear the bottom panel 3 of the beam. At the same time, due to the overall height adjustment of the support seat 2, the support seat 2 can be adjusted according to the pouring height and the required anti-camber, so as to ensure that the support seat 2 and the base 1 have a suitable anti-camber. For the base 1, the pouring requirements and difficulty are greatly reduced.

[0044] In this embodiment, the first support part 20 in the support base 2 is specifically an I-beam longitudinal beam fixedly installed on the base 1, with the two side plates of the I-beam longitudinal beam placed horizontally, and the second support part 21 is provided on the top surface of the I-beam longitudinal beam.

[0045] In this embodiment, the second support portion 21 in the support base 2 is specifically a plurality of support plates 210 stacked on the first support portion 20. 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, its specific number will be obtained based on the anti-camber value, the height of the base 1 and the first support portion 20.

[0046] Furthermore, the bottom panel 3 of the beam used to support the precast beam is placed on the second support part 21 of the support base 2, but it is not connected to the second support part 21. Instead, it is fixedly connected to the first support part 20 that has been fixed in the support base 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 factors that exist when the bottom panel 3 of the beam is connected to the movable second support part 21, making the overall precast beam platform more stable. Moreover, when the bottom panel 3 of the beam is fixedly connected to the first support part 20, it can be fixedly connected at different heights by using different connection points.

[0047] Furthermore, in some embodiments, both the first connecting plate 41 and the second connecting plate 42 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 for corresponding to the waist-shaped connecting hole 43. Different multiple connection points are formed by aligning the mounting hole 44 and the waist-shaped connecting hole 43 at different heights.

[0048] The connecting assembly 4 also includes a connecting bolt 45, which passes through 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, which serves as the first support part 20, and is vertically arranged. A waist-shaped connecting hole 43 is formed 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, parallel to the first connecting plate 41, and a mounting hole 44 is formed on it. When the beam bottom panel 3 is placed on the first support part 20, it is necessary to control the beam bottom panel 3 to move until the mounting hole 44 and the waist-shaped connecting hole 43 are aligned at a certain height. At this point, the two can be fixedly connected by connecting bolts 45. Simultaneously, the use of the waist-shaped connecting hole 43 creates multiple connection points through which connecting bolts 45 can pass in the extending direction of the waist-shaped connecting hole 43, ensuring that the connecting bolts 45 can be connected conveniently and quickly. Furthermore, the detachable connection achieved by the connecting bolts 45 also allows the beam bottom panel 3 to be quickly disassembled and reused after the precast beam is completed.

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

[0051] In one embodiment where multiple support seats 2 are provided in the width direction of the precast beam, each support seat 2 is provided with a first connecting plate 41 on one side of an adjacent support seat 2. The bottom panel 3 of the beam is provided with two second connecting plates 42 corresponding to the two first connecting plates 41 within the interval. The first connecting plates 41 and the second connecting plates 42 are parallel to the length direction of the precast beam, thereby enabling the bottom panel 3 of the beam above the multiple support seats 2 to be limited by the two first connecting plates 41 in the width direction.

[0052] Specifically, by setting multiple support seats 2 in the width direction of the precast beam, the weight of the precast beam can be reasonably distributed in the width direction, while avoiding the support seats 2 being too wide in this direction, which would make it difficult to select the structure of the support seats 2 themselves.

[0053] Furthermore, in some embodiments, the support base 2 is provided with multiple supports spaced apart in the extension direction of the precast beam.

[0054] Specifically, to avoid the support seat 2 extending too far under the precast beam, which would lead to greater material and installation difficulties, this application also effectively solves this problem by setting multiple spaced support seats 2 in the extension direction of the precast beam.

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

[0056] Multiple first panels 30 are placed on each of the support seats 2. Each of the first panels 30 has a butt plate 32 at both ends along the length of the precast beam. One end of the butt plate 32 has a waist hole 33 extending vertically, and the other end of the butt plate 32 has a butt hole. The two ends of adjacent first panels 30 are bolted together and fixed through the waist hole 33 and the butt hole.

[0057] This configuration allows the bottom panel 3 of the beam to be composed of multiple first panels 30 connected together, while adjacent first panels 30 can be bolted together with adjustable relative height through the waist hole 33 and the docking hole. Furthermore, the height of adjacent support seats 2 can still be fixedly connected when they are different, ensuring the integrity of the bottom panel 3 of the beam.

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

[0059] Two second panels 31 are disposed between adjacent first panels 30 and are respectively disposed at both ends of the bottom panel 3 of the beam. Both ends of the second panel 31 are connected to the butt plate 32. The butt plate 32 at both ends is respectively provided with the waist hole 33 and the butt hole. 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 bottom panel 3, this embodiment further provides a second panel 31 at both ends of the 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. Since 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 bottom panel 3, the bolts to the first panels 30 on the side of the second panel 31 can be directly released. At this time, since the second panel 31 is in a suspended state, the second panel 31 can be directly transferred from below the precast beam, and finally a lifting gap is formed between the two support seats 2 to directly lift the precast beam, so that the relevant lifting ropes can support and lift the precast beam upward.

[0061] Furthermore, in some embodiments, the support base 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 base 2 is detachably connected to the base 1 below via pre-embedded bolts 200.

[0062] This design further enhances the assembly and disassembly characteristics of the precast beam platform. After the precast beam construction is completed, the support base 2 and the bottom panel 3 of the beam can be disassembled and separated, so that most of the structure, except for the concrete-cast base 1, can be reused during the construction of the precast beam platform.

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

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