Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a concrete placing boom support, in particular to a concrete placing boom support and a concrete placing boom used for pouring reinforced concrete structures. Background Art
[0002] The concrete placing boom is the most commonly used concrete placing tool in cast-in-place reinforced concrete structures. It primarily consists of a steel frame, a traveling mechanism, a concrete storage hopper, safety devices, a hydraulic system, and an electrical control system. During operation, the concrete placing boom is typically placed directly on unfinished floor slab formwork or rebar cage panels. Both the rebar cage and floor slab formwork are supported by protective pads or a double-layered rebar arrangement, and the boom's legs must rest on the rebar.
[0003] During actual construction, technicians in this field discovered that due to the heavy weight of the concrete placing boom, there is a lack of stable support between the legs and the slab reinforcement. When the concrete placing boom is working, the slab reinforcement below is unevenly stressed, which makes it easy for the concrete placing boom to collapse the double-layer slab reinforcement and water and electricity pipes during the operation of the concrete placing boom, causing safety accidents. Therefore, the Chinese utility model patent with the authorization announcement date of 2024.01.30 and the authorization announcement number CN 220416650 U discloses a concrete placing boom leg support and a concrete placing boom, including a support body and a support plate; wherein the support plate is provided at the bottom of the support body, and the bottom of the support plate is provided with a first groove portion, and the first groove portion is used to engage with the slab reinforcement in the construction area. It can be seen that this technical solution reduces the degree of damage to the floor slab reinforcement when the concrete placing boom is working by providing a support plate on the concrete placing boom support and providing a groove portion at the bottom of the support plate as a reserved position for the slab reinforcement according to the spacing of the floor slab reinforcement. At the same time, the combination of the groove and the plate reinforcement effectively solves the problem of fixing the concrete placing boom at the construction site and reduces the difficulty of operation for workers, while improving the overall stability to prevent the boom from tipping over due to strong winds and mechanical collisions.
[0004] However, after application analysis, it was found that the technical solution provided by the above-mentioned utility model patent has the following deficiencies: First, in order to ensure the reliability of the support and the plate reinforcement, the size of the entire support needs to be large enough, otherwise the support will interfere with the longitudinal and transverse steel bars around the plate reinforcement; secondly, it is necessary to set a groove at the bottom of the support plate as a reserved position for the plate reinforcement according to the spacing of the floor plate reinforcement, which requires the entire support to be manufactured on-site, and it needs to be manufactured on-site after the floor formwork is supported and the plate reinforcement position is determined. Therefore, the efficiency is low, there are many influencing factors, and cross-construction operations cannot be achieved; secondly, since the entire support is customized on-site according to the floor reinforcement formwork of the construction project, it cannot be applied to other floors, let alone other construction projects, and it cannot be recycled and reused. Different supports need to be used on different floors and in different projects of the same project, which leads to waste of resources and high costs; in addition, the above-mentioned technical solution only connects the floor plate reinforcement through the groove, and the groove depth of the groove is fixed. At the same time, the height of the plate reinforcement is not uniform due to various factors. The bottom of the entire support cannot contact the floor formwork below, and the stability needs to be improved.
[0005] In summary, it is urgent to design a concrete placing boom support that can adapt to the changes in the position of slab reinforcement on different floors and in different buildings, while ensuring stable and reliable support for the concrete placing boom and avoiding interference with the vertical and horizontal reinforcement on the floors.
[0006] It should be noted that the above technical information is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or suggestion in any form that the above technical information constitutes prior art already known to those skilled in the art.

[0037] A concrete placing boom support and concrete placing boom for pouring reinforced concrete structure, such as Figures 1 to 3 As shown, the support includes a main body 1 for supporting the support rods 3 of the material distribution boom. A support plate 2 is connected to the bottom of the main body 1. The support rods 3 are the supporting legs of the material distribution boom itself. Typically, a material distribution boom has four support rods 3, which are evenly distributed and diagonally supported on the periphery of the main column of the material distribution boom. The main body 1 and support plate 2 can adopt conventional structures or the same existing structure as described in the background.
[0038] The uniqueness of this embodiment is that a support frame is connected below the support plate 2, which serves as a supporting structure for the support plate 2 and can provide sufficient support force. The support frame is connected to a vertically arranged leg assembly, which provides support force for the support frame.
[0039] The leg assembly includes a leg 1 41 that is laterally adjustable to the support frame, and a leg 2 42 that is longitudinally adjustable to the support frame. Specifically, multiple legs 1 41 and 42 can be provided, and the number of legs 1 and 2 can be varied. Preferably, two legs 1 41 and two legs 2 42 are used. Specifically, the support frame is preferably supported by four legs, which in turn provide adjustment space for each leg and support space for the adjustment structure. Each of the four legs can be repositioned relative to the support frame, thereby achieving interference avoidance and adapting to different slab reinforcements. Preferably, the lower end of each leg engages with the slab reinforcement in the reinforced concrete structure via a slot 43.
[0040] Furthermore, the upper ends of the support legs 1 41 and 2 42 are adjustably connected to the support frame via a threaded pair. Therefore, relative to the support frame, the support legs 1 41 and 2 42 can be adjusted not only in horizontal position but also in height, thereby meeting various construction conditions. Each leg is adjusted in height relative to the support frame via the threaded pair. Furthermore, since the length of the slot 43 is greater than the height of the rib, the threaded pair allows each leg to engage the rib plate while also contacting the formwork below, further improving the reliability of the support positioning. Furthermore, the height adjustment of each leg can compensate for the height difference of each rib plate or formwork.
[0041] Based on the above embodiment, as a preferred embodiment, the support frame includes longitudinal beams and transverse beams arranged in a U-shaped pattern, i.e., there are two longitudinal beams and two transverse beams. Preferably, to enhance the support effect and ensure a more uniform force is applied to the support plate 2, connecting beams 44 are provided between the longitudinal beams and the transverse beams, with a first support leg 41 connected to each transverse beam and a second support leg 42 connected to each longitudinal beam.
[0042] Both the longitudinal and transverse beams include channel steels 40 with gaps between their notches. Specifically, the channel steels 40 are arranged horizontally, with the notches facing neither upward nor downward. Instead, the notches of the channel steels 40 are arranged horizontally, with the side walls of the channel steels 40 located at the upper and lower ends of the longitudinal or transverse beam, respectively, while the bottom wall is arranged vertically. Furthermore, the notches of the two channel steels 40 face each other left and right, leaving a gap between them. These two channel steels 40 form the longitudinal or transverse beam. Preferably, the edge of the support plate 2 overlaps the upper portion of the channel steels 40 located in the inner ring to prevent the support plate 2 from blocking the gap between the two channel steels 40, thereby facilitating operation of the following structures in the longitudinal and transverse beams. Alternatively, preferably, the support plate 2 completely covers the support frame, and an operating hole 402 is provided in the support plate 2, with the operating hole 402 corresponding to the gap between the two channel steels 40 in the longitudinal and transverse beams, respectively.
[0043] Horizontal position adjustment assemblies 5 connected to the first leg 41 and the second leg 42 are respectively disposed within the channel steel 40 opposite the notch. The horizontal position adjustment assemblies 5 allow the first leg 41 and the second leg 42 to change their horizontal position relative to the support frame. This allows the position of the first leg 41 or the second leg 42 to be adaptively adjusted according to the different floors and various construction projects, thereby allowing each leg to engage with the reinforcement plate at the construction site. This improves versatility while also enhancing the stability of the support positioning. Furthermore, because the position of the first leg 41 and the second leg 42 can be adjusted, regardless of the size of the support plate 2 or the support frame, the lower legs can avoid the longitudinal and transverse reinforcement in the reinforced concrete casting structure, thereby preventing interference.
[0044] On the basis of the above embodiment, as a preferred embodiment, each crossbeam of the support frame is respectively connected to at least one leg 1 41, and each longitudinal beam of the support frame is respectively connected to at least one leg 2 42. When a crossbeam is connected to one leg 1 41, a horizontal position adjustment component 5 is arranged at either end of the crossbeam for adjusting and positioning the horizontal position of the leg 1 41; when a crossbeam is connected to two legs 1 41, a horizontal position adjustment component 5 is arranged at each end of the crossbeam for adjusting and positioning the positions of the two legs 1 41. Correspondingly, the horizontal position adjustment component 5 arranged on the longitudinal beam is also adapted to the number of legs 2 42 arranged thereon. It should be noted that if the number of legs arranged on each longitudinal beam or crossbeam exceeds two, only the legs at the two ends are connected to the horizontal position adjustment component 5, and the legs in the middle position do not need to be connected to the horizontal position adjustment component 5.
[0045] On the basis of the above embodiment, as a preferred embodiment, the threaded pair includes a connector located in the channel steel 40 and vertically stopped with the channel steel 40, the connector is threadedly connected with a bolt 61 that passes through the gap in the slot, and the tops of the legs 1 41 and 2 42 are both provided with threaded holes that are adapted to the bolt 61. This embodiment provides a preferred structural design of a threaded pair for adjusting the height of each leg, wherein the basic structure is a connector, the connector is provided in two channel steels 40 opposite to each other in the slot, the bolt 61 is threadedly connected to the connector, and the bolt 61 can adjust the height relative to the support frame, and at the same time, the bolt is threadedly connected to the leg 1 41 or the leg 2 42, and the leg 1 41 and the leg 2 42 are clamped on the plate reinforcement at different positions, so that the leg 1 41 and the leg 2 42 will not rotate. When the bolt 61 is rotated, the bolt 61 simultaneously changes its position with the connector and the corresponding leg, thereby achieving height adjustment.
[0046] It is worth mentioning why a connecting piece is required and why the bolt 61 is not directly threadedly connected to the support frame. Because the height adjustment and horizontal position adjustment of the support legs can be coupled to each other through the connecting piece, as described below.
[0047] On the basis of the above embodiment, as a preferred embodiment, the horizontal position adjustment assembly includes a screw 51 that is rotatably connected to the connecting member, and the screw 51 is threadedly connected to the sealing plate 52 at the end of the longitudinal beam or the cross beam, that is, the screw 51 is coaxially arranged with the longitudinal beam or the cross beam. When it is necessary to adjust the horizontal position of the support leg 1 41 or the support leg 2 42, it is only necessary to rotate the screw 51, and the screw 51 can drive the connecting member to slide along the longitudinal beam or the cross beam, thereby changing the horizontal position, thereby changing the horizontal position of the corresponding support leg, and at the same time, the screw 51 can position the connecting member. Preferably, the connecting member and the screw 51 are connected by a bearing seat 53, or the connecting member and the screw 51 are connected by two rings that are axially stopped and circumferentially rotated, one of which is fixedly connected to the screw 51, and the other is fixedly connected to the connecting member.
[0048] Preferably, the connecting member includes an internal threaded sleeve 62 adapted to the bolt 61 , the internal threaded sleeve 62 is fixedly connected to a connecting block 63 , and the outer wall of the connecting block 63 is in contact with the inner wall of the channel steel 40 .
[0049] Preferably, the connecting block 63 is in a rectangular shape, which is not only convenient for obtaining processing raw materials, but also convenient for processing and manufacturing. Most importantly, it can improve the sliding effect with the longitudinal beams and cross beams.
[0050] On the basis of the above embodiment, as a preferred embodiment, anti-fouling rubber rings are provided at the threaded hole ports at the upper ends of the support leg 1 41 and the support leg 2 42 to prevent the concrete at the construction site from clogging the threaded holes.
[0051] Furthermore, anti-fouling films are provided at the slots of the longitudinal beams and transverse beams, which have a similar function to the anti-fouling rubber ring 66 and are mainly used to prevent the concrete at the construction site from contaminating the internal space of the longitudinal beams and transverse beams, and to avoid affecting the sliding of the connecting parts along the longitudinal beams or transverse beams.
[0052] A concrete placing boom comprises a concrete placing boom body and a plurality of support rods 3 supported below the concrete placing boom body, wherein each support rod 3 is connected to a concrete placing boom support for pouring reinforced concrete structures as described in any one of the above embodiments.
[0053] The above content shows and describes the basic principles, main features and beneficial effects of the present invention. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
