Description

Technical Field

[0001] This utility model relates to an automatic adjustment and positioning device for pre-embedded steel plates in concrete columns, belonging to the field of building steel structure construction technology. Background Technology

[0002] With the accelerating pace of national housing construction projects, the installation and positioning technology of embedded steel plates in steel structures has become increasingly mature. Embedded steel plates in steel structures utilize high-quality steel, possessing high strength and load-bearing capacity, capable of withstanding significant pressure and loads. They can be processed on production lines, avoiding on-site cutting and processing, greatly improving efficiency. They are suitable for various building structures and bridge projects, with a wide range of applications. In steel structure buildings, embedded steel plates serve as crucial components connecting the steel and concrete structures, transferring loads and enhancing the overall structural stability and safety. However, traditional methods of installing embedded steel plates on the outside of the frame column reinforcement skeleton are problematic. Not only is welding time long, making it difficult to ensure a tight fit between the embedded steel plate and the frame column formwork, but post-weld alignment adjustments are also impossible, easily leading to positioning deviations. This results in the steel plate surface being covered with a layer of cement slurry after demolding, and may also cause defects such as surface misalignment. Cleaning is time-consuming and labor-intensive, affecting the appearance of the frame column, and these quality defects cannot be corrected or remedied, hindering subsequent processes. To solve this problem, a new positioning structure for the embedded steel plate needs to be designed to ensure the position and quality of the welded steel plate. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic adjustment and positioning device for embedded steel plates in concrete columns, which can improve the positioning accuracy and tightness of the embedded steel plates and ensure the construction quality.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an automatic adjustment and positioning device for embedded steel plates in concrete columns, comprising: an embedded steel plate, anchor bars, a movable rod, a support sleeve, and a positioning steel plate. Multiple anchor bars are fixed to the inner surface of the embedded steel plate. One end of the movable rod is vertically fixed to the inner surface of the embedded steel plate, and the other end of the movable rod is threadedly connected to the support sleeve. Two positioning steel plates are provided, each with a hole in the center, and are arranged parallel to the embedded steel plate and slidably mounted on the movable rod. A ring of double-sided adhesive is pasted around the edge of the outer surface of the embedded steel plate.

[0005] The two positioning steel plates are welded and fixed to the main reinforcement bars on both sides of the concrete column to be poured. The outer side of the embedded steel plate is attached to the template one with double-sided adhesive. The support sleeve is supported on the template two on the other side.

[0006] The length of the movable rod plus the thickness of the embedded steel plate is adapted to the cross-sectional dimensions of the concrete column to be poured.

[0007] The positioning steel plate is long and narrow, with multiple main reinforcing bars spanning its length.

[0008] The hole in the center of the positioning steel plate has a diameter of 15mm, and the diameter of the movable rod is 12mm.

[0009] The support sleeve is a truncated cone with a threaded through hole, and its large end face faces outward and contacts the template.

[0010] The double-sided adhesive is a high-adhesion blank foam double-sided adhesive.

[0011] Compared with the prior art, the present invention has the following beneficial effects.

[0012] 1. The movable rod in this utility model can slide within two positioning steel plates, thereby driving the embedded steel plate to move left and right. In this way, when installing the template, the embedded steel plate can automatically adjust its position as the template one and template two are erected, ensuring that after the template one and template two are erected, the embedded steel plate is tightly attached to the template one and its position is accurate. In the subsequent pouring process, it can also ensure that the embedded steel plate does not shift, thus improving the positioning accuracy and tightness of the embedded steel plate.

[0013] 2. This utility model improves the appearance of the pre-embedded steel plate after casting, reduces the manpower required for post-processing, shortens the process connection time, and reduces labor costs.

[0014] 3. This utility model ensures the welding quality of the purlin support plate in the later stage and ensures that the structural stress of the purlin support plate meets the design requirements. Attached Figure Description

[0023] In this utility model, the side of the pre-embedded steel plate 1 facing the inside of the concrete column to be poured is defined as the inner side, and the side facing the outside of the concrete column to be poured is defined as the outer side.

[0024] The present invention provides the following embodiments.

[0025] like Figure 1 , Figure 2 As shown, this utility model discloses an automatic adjustment and positioning device for embedded steel plates in concrete columns, comprising: an embedded steel plate 1, anchor bars 2, a movable rod 3, a support sleeve 4, and a positioning steel plate 5. Multiple anchor bars 2 are fixed to the inner side of the embedded steel plate 1. One end of the movable rod 3 is vertically fixed to the inner side of the embedded steel plate 1, and the other end of the movable rod 3 is threadedly connected to the support sleeve 4. There are two positioning steel plates 5, each with a hole in the center, arranged parallel to the embedded steel plate 1, and slidably fitted onto the movable rod 3. A ring of double-sided adhesive 6 is pasted around the edge of the outer side of the embedded steel plate 1.

[0026] like Figure 3 , Figure 4As shown, the two positioning steel plates 5 are welded and fixed to the main reinforcement 7 on both sides of the concrete column to be poured. The outer side of the embedded steel plate 1 is pasted to the template 8 with double-sided tape 6. The support sleeve 4 is supported on the template 9 on the other side.

[0027] The length of the movable rod 3 plus the thickness of the embedded steel plate 1 is adapted to the cross-sectional dimensions of the concrete column to be poured. The length of the movable rod 3 plus the thickness of the embedded steel plate 1 can be equal to the cross-sectional dimensions of the concrete column to be poured. In order to eliminate the slight bulging effect on the formwork during concrete pouring, the length of the entire device is slightly larger than (the length range is controlled within 5-10mm) the cross-sectional dimensions of the concrete column to be poured by adjusting the support sleeve 4.

[0028] The positioning steel plate 5 is long and narrow, with multiple main reinforcing bars 7 spanning its length.

[0029] The hole in the center of the positioning steel plate 5 has a diameter of 15mm, and the diameter of the movable rod 3 is 12mm.

[0030] The support sleeve 4 is a truncated cone with a threaded through hole, and its large end face faces outward and contacts the template 9.

[0031] The double-sided adhesive 6 is a high-adhesion blank foam double-sided adhesive.

[0032] The installation process of this utility model is illustrated below using the example of installing embedded steel plates in frame columns.

[0033] like Figure 3 , Figure 4 As shown, first, measure and lay out to determine the position of the embedded steel plate 1. Then, weld a positioning steel plate 5 on each of the main reinforcement bars 7 on opposite sides of the frame column. Then, insert the movable rod 3 welded on the embedded steel plate 1 into the holes on the two positioning steel plates 5. Then, screw the support sleeve 4 onto the end of the movable rod 3. When screwing, be careful not to expose the rod end of the movable rod 3. Then, stick a 10mm wide and 3mm thick high-adhesion blank foam double-sided tape on the edge of the outer side of the embedded steel plate 1. The next step is to install the frame column formwork, supporting formwork 8 and formwork 9 respectively. With formwork 8 and formwork 9 installed and secured, the embedded steel plate 1 can slide through the movable rod 3. When sliding, the anchor bar 2 and the main bar 7 restrict the rotation of the embedded steel plate 1, and the positioning steel plate 5 restricts the position of the embedded steel plate 1, ensuring that the embedded steel plate 1 will not shift. After the formwork is checked and in place, the embedded steel plate 1 is also adjusted and placed in place. The embedded steel plate 1 is tightly bonded to the surface of formwork 8 through double-sided adhesive 6, achieving precise positioning and close contact with the surface of formwork 8, thus realizing the purpose of automatic adjustment and positioning of the embedded steel plate 1.

[0034] Taking a warehouse constructed by China Railway 12th Bureau Group Co., Ltd. as an example, there are 48 frame columns that require pre-embedded steel plates on a single floor. After using this utility model for construction, various costs were saved by about 65,000 yuan and the operation time was reduced by 6 days.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
