Description

Technical Field

[0001] This invention relates to a device and method for positioning pre-reserved reinforcing bars in post-cast strips of baffles, and more particularly to a device and method for positioning pre-reserved reinforcing bars in post-cast strips of baffles for cast-in-place beams. Background Technology

[0002] As a primary load-bearing structure in modern construction projects, the construction quality of cast-in-place beams directly impacts the overall safety and stability of the project. During concrete pouring, a certain length of reinforcing steel is typically pre-installed in the formwork. This is done to ensure the bond between the steel and the concrete and to improve the strength and stability of the structure. The installation of the pre-installed reinforcing steel in the post-cast strip of the cast-in-place beam's retaining wall is a crucial indicator in cast-in-place beam construction, directly affecting the quality of the precast retaining wall installation. Therefore, a positioning device for the pre-installed reinforcing steel in the post-cast strip of the cast-in-place beam's retaining wall is an important construction device. However, currently, there is no specific device for positioning the pre-installed reinforcing steel in the post-cast strip of the cast-in-place beam's retaining wall. The installation of pre-cast reinforcement bars in the post-cast strip of cast-in-place beams often presents significant problems and potential risks. For example, after installation, the lateral edges of the reinforcement bars are not aligned, and the top surfaces are uneven, resembling "irregular wavy lines," indicating a serious deviation in linearity, sometimes exceeding specification requirements. Furthermore, the spacing between adjacent reinforcement bars is inconsistent, leading to rework. Localized rework wastes time and resources. The main reason for these problems is the inaccuracy or even absence of existing positioning clamps for the pre-cast reinforcement bars. Coupled with tight deadlines and a lack of standardized operation by on-site workers, these issues arise. There is currently no suitable device for positioning the pre-cast reinforcement in the post-cast strip of cast-in-place beams. Instead, clamps are used to position the reinforcement, which improves the positioning accuracy but does not solve the problems of inconsistent reinforcement height and linear gaps. Furthermore, its structural characteristics are not suitable for positioning the pre-cast reinforcement in the post-cast strip of cast-in-place beams, limiting its adaptability. Furthermore, the various components of the device cannot be easily installed on-site. If it is pre-installed at the processing plant, the transportation costs are high, it occupies a large space, and it is inconvenient to operate, thus limiting its practicality for widespread adoption. Therefore, there is an urgent need to design a detachable positioning clamp and its construction method suitable for the installation of pre-cast reinforcement bars in the post-pouring strip of cast-in-place beam retaining walls. This clamp should be able to meet the positioning requirements of different reinforcement bars in various situations, directly control the height, spacing, and linearity of the reinforcement bars, and be installed and disassembled on-site. This would improve the installation qualification rate of pre-cast reinforcement bars in the post-pouring strip of cast-in-place beam retaining walls, increase construction efficiency, ensure construction quality, and contribute to achieving high-quality development. This invention, through its technical feature of pre-setting the installation state of the transverse strips of the reserved reinforcing bars using a template, effectively explores and studies the technical problem of using clamps to position the reinforcing bars at a technical level. The statements herein provide only background information related to this invention and do not necessarily constitute prior art. Based on the technical disclosure provided by the applicant on January 10, 2024, which addresses practical technical problems encountered during the work process, and similar patent documents obtained through retrieval (patent number: ZL202022920708.2), as well as the existing technical problems, technical features, and technical effects in the background art, the technical solution of this invention is proposed.

Rod part V 922 is placed in receiving groove IV 95, causing nut part IV 923 to rotate on rod part V 922, so that the inner end face of nut part IV 923 acts on the horizontal part of beam part II 99. Using nut part I 85, rod part I 82, and rod part II 83, the vertical part of beam part II 99 is placed in the reserved reinforcement section of the post-cast strip of the baffle. According to the distance between the layers of the transverse strips of the reserved reinforcement, using nut part III 913 and rod part IV 912, the position of seat part 911 on the vertical part of beam part II 99 is adjusted according to the length scale lines on the vertical part of beam part II 99. Multiple supports 91, matching the number of layers of the transverse strips of the reserved reinforcement, are installed on the vertical part of beam part II 99. According to the length of the transverse strips of the reserved reinforcement, using rod part V 922 and nut part IV 923, the position of plate part 921 on the horizontal part of beam part II 99 is adjusted according to the length scale lines on the horizontal part of beam part II 99, so that the position of plate part 921 corresponds to the length of the transverse strips of the reserved reinforcement. Place the transverse strips of the reserved reinforcing bars onto the receiving groove V914, ensuring that the ends of the transverse strips contact the front side of the plate 921. After the installation of the transverse strips of the reserved reinforcing bars in the same row is completed, place two longitudinal ribs of the reserved reinforcing bars on the transverse strips of the reserved reinforcing bars in the same layer. Weld the longitudinal ribs of the reserved reinforcing bars to the transverse strips of the reserved reinforcing bars.

Separate the beams and move the rods 398 on the receiving trough 284 according to the length scale line on the horizontal part of the beam I 81. Position the beam II 99 on the horizontal strip installation position of the reserved steel bar in the next row. After the installation of the reserved steel bar is completed, separate the horizontal strip of the reserved steel bar from the seat 911. Take out the first column 6 from one side of the reserved steel bar part of the baffle post-cast strip and take out the second column 7 from the other side of the reserved steel bar part of the baffle post-cast strip.

[0076] In verifying this invention, the inventors abandoned the existing technical features that all use clamps to position the reinforcing bars. Instead, they first proposed a technical feature of pre-setting the installation state of the transverse strips of the reserved reinforcing bars using a template. This resulted in the first unexpected technical effect: achieving neat installation of the transverse strips of the reserved reinforcing bars; the second unexpected technical effect: achieving precise positioning of the transverse strips of the reserved reinforcing bars; the third unexpected technical effect: achieving precise alignment of the length of the transverse strips of the reserved reinforcing bars; the fourth unexpected technical effect: achieving coordinated installation of the longitudinal ribs of the reserved reinforcing bars, improving installation efficiency; and the fifth unexpected technical effect: achieving standardized processing of the reserved positions of the baffle post-pouring strips, improving the connection effect between cast-in-place beams.

[0077] In a second embodiment of the present invention, the support component, the first main component, and the second main component are interconnected by a template-based pre-setting method for the installation state of the transverse strips of the reserved reinforcing bars.

[0078] In this embodiment, the first main component is connected to the support component and the second main component by positioning the installation position of the transverse strip of the reserved reinforcing bar.

[0079] In this embodiment, the support component is configured to include a first fixing plate 1 and a second fixing plate 3 or to include a first column 6, a second column 7, and a second intermediate connecting beam 8.

[0080] In this embodiment, the first main component is configured as an intermediate connecting beam 2 or includes a lifting beam 9 and a support 91.

[0081] In this embodiment, the second main component is configured to include a magnet base 4 and a standard rod 5 or a positioning plate 92.

[0082] The second embodiment of the present invention is based on the first embodiment. In the second embodiment of the present invention, the steps are as follows: the supporting component supports the first main component, the first main component positions the installation location of the transverse strip of the reserved reinforcing bar, the second main component sets the length of the transverse strip of the reserved reinforcing bar at a fixed distance, and the installation state of the transverse strip of the reserved reinforcing bar is pre-set in a template-like manner.

[0083] The second embodiment of the present invention is based on the first embodiment.

[0084] This invention has the following characteristics: 1. Due to the design of supporting components, a first main component, and a second main component, the supporting components support the first main component, the first main component positions the installation location of the transverse strips of the reserved reinforcing bars, and the second main component sets the length of the transverse strips of the reserved reinforcing bars. This allows for template-based pre-setting of the installation state of the transverse strips of the reserved reinforcing bars, solving the technical problem of using clamps to position the reinforcing bars and thus improving the positioning and installation accuracy of the reserved reinforcing bars in the post-pouring strip of the baffle.

[0085] 2. By designing a first fixing plate 1 and a second fixing plate 3, or including a first column 6, a second column 7 and a second intermediate connecting beam 8, support is provided at both ends.

[0086] 3. Due to the design of intermediate connecting beam 2, hanging beam 9 and support 91, the horizontal strips of the reserved steel bars can be placed in a fixed position.

[0087] 4. Due to the design of magnet base 4 and standard rod 5 or positioning plate 92, the length of the transverse strip of the reserved steel bar can be measured at a fixed distance.

[0088] 5. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0089] 6. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.

[0090] Other technical features that connect the support components, the first main component, and the second main component to the template-style pre-set installation state of the transverse strips of the reserved reinforcing bars are also embodiments of the present invention. Furthermore, the technical features of the above embodiments can be combined arbitrarily. In order to meet the requirements of the Patent Law, the Patent Implementation Regulations, and the Examination Guidelines, all possible combinations of the technical features in the above embodiments will not be described.

[0091] The above embodiments are merely one implementation of the positioning device and method for reserving reinforcing bars in the post-cast strip of the baffle for cast-in-place beams provided by the present invention. Any other modifications to the solution provided by the present invention, including adding or reducing components or steps, or applying the present invention to other technical fields similar to the present invention, shall all fall within the protection scope of the present invention.
