Description

Technical Field

[0001] This utility model relates to the field of steel structure factory construction technology, specifically to a device for pre-reserved holes in steel structure foundations that does not require roughening. Background Technology

[0002] During the construction of a steel structure factory building, it is necessary to install the steel structure warehouse support legs. This is usually done by pouring concrete to fix the warehouse support legs into pre-drilled holes, the cross-sectional dimensions of which are slightly larger than the cross-sectional dimensions of the warehouse support legs. After the pre-drilled holes are poured, a second layer of concrete is poured inside them. Therefore, the inside of the pre-drilled holes needs to be roughened to ensure the stability of the second layer of concrete.

[0003] However, due to the small size of the reserved openings, the formwork is difficult to remove after casting, making the roughening process of the reserved openings difficult as well. On-site formwork is generally removed destructively, resulting in severe material damage that is difficult to reuse, and the roughening process is of poor quality and cannot meet design and specification requirements. Therefore, a roughening-free device for reserved holes in steel structure foundations was designed. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1, please refer to Figures 1-10 The steel structure foundation pre-reserved hole no-scraping device includes four sets of side plates 1, which are arranged in a square structure. Each set of side plates 1 has a triangular plate 2 on its outer surface. The triangular plate 2 and the side plate 1 are provided with a tenon and mortise structure 3. The tenon and mortise structure 3 is used to engage the triangular plate 2 and the side plate 1. The outer surface of the triangular plate 2 is fixed with a no-scraping grout stop strip 4, and the outer surface of the no-scraping grout stop strip 4 is fixed with several sets of protrusions 5.

[0033] Four sets of reinforcing plates 6 are provided at the four corners of the four sets of side plates 1. An adjustable support rod 7 is provided between the two sets of reinforcing plates 6 that are set diagonally. The adjustable support rod 7 can be adjusted to press the reinforcing plate 6 against the inner wall of the side plate 1.

[0034] The mortise and tenon structure 3 includes a first T-shaped groove 31 opened on the side plate 1, and a first T-shaped strip 32 fixed on the surface of the triangular plate 2. The first T-shaped strip 32 is slidably engaged in the first T-shaped groove 31.

[0035] A second T-shaped slot 12 is provided at one end of the side plate 1, and a second T-shaped strip 13 is provided at the other end of the side plate 1;

[0036] The adjustable support rod 7 includes two sets of connecting cylinders 71 connected to the reinforcing plate 6. A crossbar 72 is provided between the two sets of connecting cylinders 71. A threaded block 73 is fixed at the end of the crossbar 72. A threaded groove 74 is opened inside the connecting cylinder 71. The threaded block 73 is threadedly connected in the threaded groove 74.

[0037] In this technical solution, during the construction of the reserved holes in the steel structure workshop, the second T-shaped clip 13 on one set of side plates 1 is first inserted into the second T-shaped slot 12 on another set of side plates 1, so that the four sets of side plates 1 form Figure 1 The square structure shown is then inserted into the first T-shaped slot 31 to fix the triangular plate 2 to the outer surface of the side plate 1. Then, the no-scraping grout-stopping strip 4 is wrapped and fixed to the outer surface of the triangular plate 2 to form a no-scraping structure. Finally, the no-scraping structure is placed in the position where the reserved hole needs to be set, and concrete is poured to the outside of the no-scraping structure. After the concrete is poured and fixed, the first T-shaped slot 32 is slid out of the first T-shaped slot 31 by pulling the side plate 1, so that the side plate 1 and the triangular plate 2 are separated. The side plate 1 is moved out first. After the side plate 1 is moved out, the triangular plate 2 loses the resistance of the side plate 1. At this time, the triangular plate 2 can move inward, so that the triangular plate 2 drives the no-scraping grout-stopping strip 4 and the protrusion 5 to move out of the poured concrete. Then, the triangular plate 2 is lifted up and the triangular plate 2, together with the no-scraping grout-stopping strip 4 and the protrusion 5, is moved out, thus leaving a pit in the concrete to form a reserved hole.

[0038] In this technical solution, after the four sets of side plates 1 form a square structure, four sets of reinforcing plates 6 are set and placed at the four corners respectively. Then, the reinforcing plates 6 are supported by the adjustable support rod 7. By rotating the connecting cylinder 71, the threaded block 73 rotates in the threaded groove 74, which allows the connecting cylinder 71 to move relative to the crossbar 72, thereby adjusting the overall length of the adjustable support rod 7. By increasing the length of the adjustable support rod 7, the reinforcing plate 6 is brought into contact, making the reinforcing plate 6 fit more tightly with the four corners, thereby improving the support effect of the reinforcing plate 6 on the side plates 1 and making the connection between the four sets of side plates 1 more stable.

[0039] To further increase the stability between the four sets of side plates 1, a bottom plate 19 for sealing is provided at the bottom of the side plate 1. The bottom plate 19 can not only increase the stability of the bottom connection of the four sets of side plates 1, but also isolate the concrete to prevent the concrete from entering the interior of the side plate 1. The bottom plate 19 can be fixed to the side plate 1 by existing bolts or screws.

[0040] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-10 The protrusion 5 includes a first protrusion 51, a second protrusion 52 and a third protrusion 53 with successively decreasing diameters. The first protrusion 51 is fixed to the outer surface of the triangle plate 2, the second protrusion 52 is fixed to the outer surface of the first protrusion 51, and the third protrusion 53 is fixed to the outer surface of the second protrusion 52.

[0041] In this technical solution, by setting the protrusion 5 as a first protrusion 51, a second protrusion 52, and a third protrusion 53 with successively decreasing diameters, the outer concrete of the side plate 1 can form an inwardly recessed groove when pouring concrete. The groove forms a three-layer platform structure with successively decreasing diameters, which makes the secondary concrete more tightly connected to the primary concrete during the secondary pouring, thereby further improving the stability of concrete pouring.

[0042] Example 3 is an improvement upon Example 2. For details, please refer to [link / reference]. Figures 1-10 It also includes several sets of first extension plates 11, one end of each set of first extension plates 11 is provided with a third T-shaped slot 14 that cooperates with the second T-shaped slot 13, and the other end of each set of first extension plates 11 is fixed with a third T-shaped slot 15 that cooperates with the second T-shaped slot 12.

[0043] It also includes several sets of second extension plates 16, with a fourth T-shaped clip 17 fixed on each set of second extension plates 16, and a fourth T-shaped slot 18 that mates with the fourth T-shaped clip 17 on the first extension plate 11.

[0044] In this technical solution, due to the varying sizes of the support legs during the construction of the steel structure workshop, the square structure composed of four sets of side plates 1 may not be sufficient to meet construction requirements when dealing with larger support legs. This results in smaller pre-drilled holes, making it inconvenient to install larger support legs. Therefore, if... Figure 8 and Figure 9As shown, before assembling the four sets of side panels 1, the first extension plate 11 is installed on each set of side panels 1. The third T-shaped clip 15 on the first extension plate 11 is inserted into the second T-shaped slot 12 on the side panel 1, and the second T-shaped clip 13 on the side panel 1 is inserted into the third T-shaped slot 14 on the first extension plate 11. The assembly of the first extension plate 11 and the side panel 1 is completed. After the first extension plate 11 and the side panel 1 are assembled, a square structure with a larger length and width is formed, which facilitates the installation of larger warehouse support legs.

[0045] In this technical solution, after the first extension plate 11 is assembled with the side plate 1, a square structure with a larger length and width is formed. At this time, through the second extension plate 16, which has the same inclined structure as the triangular plate 2, the second extension plate 16 is connected to the first extension plate 11 by inserting the fourth T-shaped clip 17 on the second extension plate 16 into the fourth T-shaped slot 18 on the first extension plate 11, thereby extending the length of the triangular plate 2 so that the triangular plate 2 can adapt to the changes of the side plate 1. In addition, the no-scraping anti-grouting strip 4 can be cut to the corresponding length and width according to the different assembly length and width.

[0046] Example 4 is an improvement upon Example 3. For details, please refer to [link / reference]. Figures 1-10 The outer surface of the reinforcing plate 6 is provided with a rotating groove 8, and a rotating shaft 9 is rotatably arranged in the rotating groove 8. A rotating cylinder 10 is fixed on the rotating shaft 9, and the end of the connecting cylinder 71 is rotatably connected to the rotating cylinder 10.

[0047] In this technical solution, after the four sets of side plates 1 and the first extension plate 11 form square structures of different sizes, the distance and length between the diagonals change. Although the adjustable support rod 7 can adjust the length, if the angle between the adjustable support rod 7 and the reinforcing plate 6 cannot be changed, the reinforcing plate 6 at the diagonal cannot be fully attached to the corner, thus the adjustable support rod 7 cannot support the reinforcing plate 6. Therefore, when the adjustable support rod 7 is installed on square structures of different sizes, the rotating cylinder 10 can rotate inside the rotating groove 8 through the set rotating groove 8 and rotating shaft 9, changing the angle of the rotating cylinder 10. And through the rotating connection between the connecting cylinder 71 and the rotating cylinder 10, the rotating cylinder 10 will not affect the rotation of the connecting cylinder 71. Thus, while the length of the adjustable support rod 7 is adjusted, the included angle between it and the reinforcing plate 6 can be changed, thereby conveniently meeting the requirements of different distances and angles of the diagonals.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
