Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a pre-embedded part positioning construction device. Background Technology

[0002] With the improvement of construction techniques and quality standards, various construction methods have emerged for different types of structures. These methods are widely used in the construction process. Traditional special equipment foundation embedded part positioning technology, which involves welding positioning bolts to the reinforcing steel frame, suffers from poor precision, is prone to displacement due to disturbances, and involves significant rework, greatly increasing construction time and costs. Furthermore, it requires highly skilled operators during construction, and improper operation can easily lead to common quality defects such as angular errors and positioning deviations. If the embedded parts exhibit errors exceeding the acceptable range after concrete pouring, they must be removed and reconstructed, resulting in substantial rework costs. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a pre-embedded component positioning construction device. A first concrete layer and a second concrete layer are stacked on the ground. Pre-embedded components are embedded within the first and second concrete layers. The device includes pre-embedded components, a first support, a second support, and a channel steel assembly. Each pre-embedded component includes a base plate, an intermediate plate, a top plate, and multiple reinforcing bars. The base plate, intermediate plate, and top plate are spaced apart, and the multiple reinforcing bars sequentially connect the top plate, intermediate plate, and base plate. The bottom of the first support is fixedly installed on the ground, and its top surface is connected to the base plate. The first support is located within the first concrete layer. The bottom of the second support is fixedly installed on the top surface of the first concrete layer. One end of the channel steel assembly is connected to the top surface of the second support, and the other end is connected to the top plate.

[0004] Furthermore, the first bracket includes multiple first columns, multiple first crossbars, and multiple first mounting bases. The multiple first columns and multiple first crossbars are connected in an alternating manner to form a frame structure, and the multiple first mounting bases are connected one-to-one to the bottom surface of the multiple first columns.

[0005] Furthermore, the first bracket also includes a first diagonal brace and a first fixing plate, with one end of the first diagonal brace fixedly connected to the first column and the other end of the first diagonal brace fixedly connected to the first fixing plate.

[0006] Furthermore, the second bracket includes multiple second uprights, multiple second crossbars, and multiple second mounting bases. The multiple second uprights and multiple second crossbars are connected in an alternating manner to form a frame structure, and the multiple second mounting bases are connected one-to-one to the bottom surface of the multiple second uprights.

[0007] Furthermore, the second bracket also includes a second diagonal brace and a second fixing plate. One end of the second diagonal brace is fixedly connected to the second column, and the other end of the second diagonal brace is fixedly connected to the second fixing plate.

[0008] Furthermore, the channel steel assembly includes a first channel steel and a second channel steel, the first channel steel being vertically connected to the second channel steel, one end of the first channel steel being fixedly connected to the top surface of the second bracket, and the other end of the first channel steel being fixedly connected to the top plate, one end of the second channel steel being fixedly connected to the top surface of the second bracket, and the other end of the second channel steel being fixedly connected to the top plate.

[0009] Furthermore, the top surface of the second bracket is flush with the top surface of the top plate.

[0010] Furthermore, it also includes adjustable bolts that securely connect the first bracket to the ground.

[0011] Furthermore, the adjustable bolt includes a screw, a first nut, and a second nut. The bottom of the first bracket is provided with a mounting hole, through which the screw passes. The first nut is located on the bottom of the first bracket away from the ground, and the second nut is located on the bottom of the first bracket close to the ground. The first nut is threadedly connected to the screw, and the second nut is threadedly connected to the screw.

[0012] Furthermore, multiple of the aforementioned reinforcing bars are spaced apart circumferentially along the top plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention uses a first bracket to support and position the lower half of the embedded part before binding the concrete reinforcement cage and pouring the first layer of concrete. This ensures the high-precision positioning and installation requirements of the embedded part for special equipment. A second bracket and channel steel assembly are then installed on the first concrete layer to position the upper half of the embedded part. The concrete reinforcement cage is then bound, and a second concrete layer is poured, ultimately forming the second concrete layer (concrete foundation). This avoids the problems associated with traditional construction methods, where the embedded part's positioning can shift due to trampling or impacts during concrete pouring, leading to extensive rework. Compared to ordinary steel pipe supports fabricated on-site, the first, second, and channel steel components in this embodiment are all steel structures, making them more stable and robust. They can support heavier embedded parts and exhibit only minor deformation when subjected to external disturbances. Using the first, second, and channel steel components for embedded part positioning effectively reduces disturbances, keeping the accuracy error within acceptable limits and ensuring the quality of construction.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other. For ease of description, the words "upper," "lower," "left," and "right" appearing below only indicate that they are consistent with the upper, lower, left, and right directions of the drawings themselves, and do not limit the structure.

[0023] like Figures 1 to 5As shown, this utility model proposes a pre-embedded part positioning construction device. A first concrete layer 10 and a second concrete layer are stacked on the ground. The pre-embedded part 1 is embedded in the first concrete layer 10 and the second concrete layer. The device includes the pre-embedded part 1, a first support 2, a second support 3, and a channel steel assembly 4. The pre-embedded part 1 includes a base plate 11, a middle plate 12, a top plate 13, and multiple reinforcing bars 14. The base plate 11, the middle plate 12, and the top plate 13 are spaced apart. The multiple reinforcing bars 14 pass through and connect the top plate 13, the middle plate 12, and the base plate 11 in sequence. The bottom of the first support 2 is fixedly installed on the ground, and the top surface of the first support 2 is connected to the base plate 11. The first support 2 is located in the first concrete layer 10. The bottom of the second support 3 is fixedly installed on the top surface of the first concrete layer 10. One end of the channel steel assembly 4 is connected to the top surface of the second support 3, and the other end of the channel steel assembly 4 is connected to the top plate 13. Specifically, the first support 2 and the second support 3 can be designed according to the construction drawings and design requirements, as well as the overall shape of the embedded part 1. For example, in this embodiment, the bottom plate 11 and top plate 13 of the embedded part 1 are both rectangular structures, and the corresponding first support 2 and second support 3 are also designed as rectangular structures. Before the construction of the embedded part 1, the preparation of the first support 2 and the second support 3 is completed first. At the same time, by applying BIM technology, the construction personnel are given a visual briefing on the assembly and positioning process of the embedded part, reducing personnel errors and further reducing the rework rate. After the embedded part 1 arrives on site and construction begins, the lower half of the embedded part 1 is supported and positioned by the first support 2, and then the concrete reinforcement cage is tied and the first concrete is poured. After the pouring is completed, the first concrete layer 10 is formed to ensure the high-precision positioning and installation requirements of the embedded part 1 required by the special equipment. Then, the second support 3 and the channel steel assembly 4 are positioned and installed on the first poured concrete layer 10 to position the upper part of the embedded part 1. The concrete reinforcement cage is then tied, and the second concrete layer is poured, ultimately forming the second poured concrete layer. Compared to a single-pour construction method, achieving the concrete structure's formation through two pours further ensures the positioning accuracy of the embedded part 1. This avoids the problems associated with traditional construction methods, where the embedded part 1's positioning can shift due to trampling or impacts during concrete pouring, leading to extensive rework. Compared to ordinary steel pipe supports fabricated on-site, the first support 2, second support 3, and channel steel assembly 4 in this embodiment are all steel structures, making them more stable and robust. They can support the heavier embedded part 1 and only experience minor deformation when subjected to external disturbances. Using the first support 2, second support 3, and channel steel assembly 4 for positioning the embedded part 1 effectively reduces disturbances, keeping the accuracy error within acceptable limits. Specifically, channel steel or steel scraps are preferred for the fabrication of the first support 2, the second support 3, and the channel steel assembly 4, thereby enabling the recycling of scrap materials and conforming to the concept of green construction.Before the positioning and installation of the first support 2, three permanent control points will be set up on site to ensure the accuracy of on-site measurements and the needs of equipment foundation positioning. All measurement work will be carried out based on these three control points for layout and verification. Regular inspections and re-measurements of the control network, both overall and in parts, will be conducted. Each re-measurement result must be documented in a written report to ensure the stability, reliability, and accuracy of the control network. The spatial positioning coordinates of the component center and the outer edge of the measurement control line in the BIM model will be used as the basis for the positioning measurement of the first support 2. During component installation, a total station will be used for measurement control and adjustment to ensure that the component installation meets design, specification, and positioning requirements.

[0024] In one embodiment, the first support 2 includes multiple first columns 21, multiple first crossbars 22, and multiple first mounting bases 23. The multiple first columns 21 and multiple first crossbars 22 are staggered to form a frame structure, and the multiple first mounting bases 23 are connected one-to-one to the bottom surface of the multiple first columns 21. Specifically, the top surface of the frame structure formed by the first support 2 is equal to the size of the base plate 11, so as to support the base plate 11.

[0025] In one embodiment, the first support 2 further includes a first diagonal brace 24 and a first fixing plate 25. One end of the first diagonal brace 24 is fixedly connected to the first column 25, and the other end of the first diagonal brace 24 is fixedly connected to the first fixing plate 25. The stability of the frame structure is further improved by the first diagonal brace 24 and the first fixing plate 25.

[0026] In one embodiment, the second support 3 includes multiple second columns 31, multiple second crossbars 32, and multiple second mounting bases 33. The multiple second columns 31 and multiple second crossbars 32 are staggered to form a frame structure, and the multiple second mounting bases 33 are connected one-to-one to the bottom surface of the multiple second columns 31. Specifically, the frame structure formed by the second support 3 has a receiving cavity inside, which is used to receive the top plate 13. The top surface of the frame structure formed by the second support 3 is flush with the top surface of the top plate 13. Then, the channel steel assembly 4 is installed. The channel steel assembly 4 is spot welded to the second support 3 and the top plate 13 for fixation, in order to constrain the planar and vertical deviation of the embedded part 1, prevent external impact from causing the embedded part 1 to deviate, and ensure the installation accuracy of the embedded part 1.

[0027] In one embodiment, the second support 3 further includes a second diagonal brace 34 and a second fixing plate 35. One end of the second diagonal brace 34 is fixedly connected to the second column 31, and the other end of the second diagonal brace 34 is fixedly connected to the second fixing plate 35. The stability of the frame structure is further improved by the second diagonal brace 34 and the second fixing plate 35.

[0028] In one embodiment, the channel steel assembly 4 includes a first channel steel 41 and a second channel steel 42. The first channel steel 41 is vertically connected to the second channel steel 42. One end of the first channel steel 41 is fixedly connected to the top surface of the second bracket 3, and the other end of the first channel steel 42 is fixedly connected to the top plate 13. One end of the second channel steel 42 is fixedly connected to the top surface of the second bracket 3, and the other end of the second channel steel 42 is fixedly connected to the top plate 13. The first channel steel 41 is used to constrain the flatness and positioning accuracy of the embedded part 1 in the length direction, and the second channel steel 42 is used to constrain the flatness and positioning accuracy of the embedded part 1 in the width direction.

[0029] In one embodiment, the top surface of the second bracket 3 is flush with the top surface of the top plate 13.

[0030] In one embodiment, an adjustable bolt 5 is also included, which securely connects the first bracket 2 and the ground.

[0031] In one embodiment, the adjustable bolt 5 includes a screw 51, a first nut 52, and a second nut 53. The bottom of the first bracket 2 has a mounting hole through which the screw 51 passes. The first nut 52 is located on the bottom of the first bracket 2 away from the ground, and the second nut 53 is located on the bottom of the first bracket 2 near the ground. The first nut 52 and the second nut 53 are threadedly connected to the screw 51. Specifically, when installing the first bracket on the ground, a total station is used on-site to precisely position the plane of the embedded part 1. The error strictly adheres to the requirements of the construction standards, achieving high-precision positioning of the embedded part 1 on its plane. After verifying the positioning, reinforcement is performed. If a small deviation occurs in the positioning, the position of the first bracket 2 is fine-tuned using the adjustable bolt 5, thereby achieving fine-tuning of the flatness of the embedded part 1 fixedly installed on the first bracket 2.

[0032] In one embodiment, multiple reinforcing bars 14 are spaced apart circumferentially along the top plate 13.
