Description

Technical Field

[0001] This utility model relates to the field of rebar positioning technology, specifically a rebar positioning device for beams and slabs in building construction. Background Technology

[0002] In the construction of building beams and slabs, formwork is first used for support. After the formwork is in place, the woven reinforcing bars are placed inside the mold, and supports such as stones and bricks are used to elevate the bars, creating a certain distance between the bars and the bottom formwork to prevent them from being exposed after mortar is poured. However, this existing method results in low stability in the connection between the supports and the reinforcing bars. During mortar pouring, the impact of the mortar can easily cause these supports to shift, failing to effectively support the reinforcing bars. This leads to the reinforcing bars sagging and contacting the bottom formwork, resulting in exposed reinforcing bars in the cast-in-place beams and slabs, creating defects.

[0003] Therefore, there is an urgent need to design a rebar positioning device for building construction beams and slabs to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a rebar positioning device for building construction beams and slabs, which effectively solves the problems of low stability when positioning rebars in beams and slabs in the existing technology, and the rebars being easily displaced by the impact of mortar during mortar pouring, resulting in exposed rebars and defects in the cast-in-place building beams and slabs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rebar positioning device for beams and slabs in building construction, the device comprising: A positioning tube with several positioning grooves evenly distributed on its top surface; and Several support plates are evenly distributed and fixedly connected to both sides of the positioning tube. Each support plate is an obtuse triangle, with one corner away from the positioning tube lower than the bottom surface of the positioning tube.

[0006] Preferably, a plurality of first through holes penetrating the bottom surface of the positioning tube are evenly formed between every two adjacent positioning grooves on the top surface of the positioning tube.

[0007] Preferably, the positioning tube has several evenly distributed second through holes on both sides.

[0008] Preferably, each of the support plates has a third through hole.

[0009] Preferably, a connecting rod is fixedly connected between several support plates located on the same side of the positioning tube.

[0010] Preferably, the bottom surface of the positioning tube has a plurality of fourth through holes that are alternately distributed with the first through hole.

[0011] This utility model provides a device for positioning steel bars in beams and slabs during building construction, which has the following beneficial effects: This rebar positioning device for building construction beams and slabs, through the arrangement of positioning pipes, positioning grooves, and support plates, facilitates the laying and installation of rebars, provides stable support for the positioning pipes, and prevents rebars from falling off during vibration operations and from being exposed. By opening several first and second through holes in the positioning pipes, a third through hole in the support plate, and several fourth through holes at the bottom of the positioning pipes, the weight of the device is effectively reduced, construction costs are controlled, the possibility of voids inside the beams and slabs is reduced, and the quality of beam and slab construction is improved. The connecting rods connect several support plates on the same side into one unit, effectively improving the deformation resistance of the support plates and thus enhancing the overall stability of the device.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a device for positioning reinforcing bars in beams and slabs during building construction, comprising: A positioning tube 1 has a plurality of positioning grooves 11 evenly distributed on its top surface. The positioning grooves 11 are used to position and support the reinforcing bars of the beam and slab, and the spacing of the positioning grooves 11 is consistent with the data on the construction drawings. In this embodiment, a plurality of first through holes 12 penetrating the bottom surface of the positioning tube 1 are evenly distributed between every two adjacent positioning grooves 11 on the top surface of the positioning tube 1. A plurality of evenly distributed second through holes 13 are penetrating through both sides of the positioning tube 1. A plurality of fourth through holes 14 are distributed alternately with the first through holes 12 on the bottom surface of the positioning tube 1, which effectively avoids the possibility of insufficient number of first through holes 12. The insufficient mortar filling under the positioning pipe 1 is due to its proximity to the ground or the lower formwork. During construction, mortar can enter the positioning pipe 1 through the first through hole 12 and the second through hole 13 and exit through the fourth through hole 14. This reduces voids inside the beam and slab during mortar pouring, effectively reduces the weight of the device, improves the construction quality of the beam and slab, and helps control costs. Furthermore, the impact on the structural strength of the positioning pipe 1 can be reduced by controlling the number and position of the first through hole 12 and the second through hole 13. Several support plates 2 are evenly distributed on both sides of the positioning tube 1. Each support plate 2 is an obtuse triangle, with the vertex of its corner furthest from the positioning tube 1 located below the bottom surface of the positioning tube 1. This creates a height difference between the bottom of the positioning tube 1 and the support plates 2, allowing mortar to enter the space below the positioning tube 1. The corner of the support plate 2 furthest from the positioning tube 1 is also relatively sharp, making it easy to penetrate the bottom template. Furthermore, being far from the center of gravity of the device, it prevents the device from shifting or tipping over due to mortar impact after the reinforcement is installed. In this embodiment, the positions of the support plates 2 on both sides of the positioning tube 1 correspond one-to-one with the positioning grooves 11, and each support plate 2 has a [missing information - likely a groove or groove]. The third through hole 21 is not limited in shape and can be circular, elliptical, triangular, rhomboid, or square. The larger the area of ​​the third through hole 21, the better, without excessively affecting the structural strength of the support plate. This structural design is basically consistent with the design ideas of the first through hole 12 and the second through hole 13, which can reduce the weight of the device and help control costs. A connecting rod 22 is fixedly welded between several support plates 2 on the same side of the positioning tube 1, so that several support plates 2 on the same side form a whole, which can improve the structural stability of the device and improve the deformation resistance of the support plate 2.

[0016] The working principle and usage of this utility model are as follows: First, after the beam and slab formwork is completed in the building construction, several of these devices can be evenly arranged in the formwork along the axial direction of the beam and slab reinforcement. The corner of the support plate 2 away from the positioning pipe 1 contacts the formwork. Since the support plate 2 is an obtuse triangle, the corner away from the positioning pipe 1 is lower than the bottom surface of the positioning pipe 1, so that a certain filling space is left between the bottom surface of the positioning pipe 1 and the formwork or ground below it, allowing mortar to enter. Then, the steel bars of the beam and slab are laid according to the position of the positioning groove 11. The steel bars are partially embedded in the positioning groove 11, so that the steel bars are evenly distributed and stable support is obtained. After the steel bars are laid on the positioning groove 11, they can be spot welded with a welding machine or tied together to connect the device and the steel bars as one unit, further improving the support stability. Finally, after the reinforcing bars are laid, grouting and other pouring operations can be carried out. When pouring mortar, the device is not easy to shift or tip over due to the setting of support plate 2, connecting rod 22, etc. When using vibrating equipment such as vibrators, compared with conventional bricks, stones and other supports, this device has higher stability and can stably support the reinforcing bars. The reinforcing bars are not easy to fall to the bottom of the formwork and cause the problem of reinforcing bars being exposed. Moreover, the entire device can be made of steel, which is beneficial to improving the rigidity of beams and slabs.

[0017] In summary, this utility model has the following advantages: This rebar positioning device for building construction beams and slabs, through the setting of positioning pipes, positioning grooves, and support plates, facilitates the laying and installation of rebars, provides stable support for the positioning pipes, and prevents the rebars from falling off during vibration operations and from being exposed. By setting several first and second through holes in the positioning pipes, a third through hole in the support plate, and several fourth through holes at the bottom of the positioning pipes, the weight of the device is effectively reduced, construction costs are controlled, the possibility of voids in the beams and slabs is reduced, and the quality of beam and slab construction is improved. The setting of connecting rods connects several support plates on the same side into one unit, effectively improving the deformation resistance of the support plates, thereby improving the overall stability of the device.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
