Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a positioning structure for additional reinforcing bars on profiled steel sheets. Background Technology
[0002] Currently, the most commonly used formwork-free and scaffold-free floor slabs on the market include semi-precast concrete truss floor slabs and fully precast concrete floor slabs. However, in steel structure construction, profiled steel sheets are generally used as the bottom formwork, eliminating the need for a bottom scaffolding support system. Profiled steel sheets are formed by roll-forming coated or plated steel sheets into a corrugated cross-section along the width of the sheet, offering advantages such as cost savings and higher safety.
[0003] Corrugated steel sheets are usually reinforced with additional load-bearing bars at the bottom. However, since these additional bars do not have vertically tied distribution bars, it is difficult to position and fix a single additional bar. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a positioning structure for additional reinforcing bars on profiled steel sheets, which solves the problem of inconvenient positioning and binding of additional reinforcing bars on profiled steel sheets.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a positioning structure for additional reinforcing bars on profiled steel sheets, including a bottom groove set on the profiled steel sheet, a plurality of pads set in the bottom groove, the pads being perpendicular to the extension direction of the bottom groove, and the length of the pads being adapted to the width of the bottom groove.
[0006] The top of the pad block is provided with a positioning groove for placing additional reinforcing bars, and the direction of the positioning groove is consistent with the extension direction of the bottom groove.
[0007] The pad has a binding groove, and binding wires are threaded through the binding groove to bind and fix the additional reinforcing bars to the pad.
[0008] Optionally, the binding groove is an arc-shaped groove with openings at both ends. The binding groove is located below the positioning groove, and the openings at both ends of the binding groove are located on both sides of the positioning groove.
[0009] Optionally, two sets of positioning slots are provided, and the two sets of positioning slots are arranged adjacent to each other.
[0010] Optionally, the positioning groove is an arc-shaped groove with a semi-circular cross-section.
[0011] Optionally, the cross-section of the pad is arch-shaped, and a groove is provided at the bottom of the pad.
[0012] Optionally, several sets of vertically permeable grouting holes are spaced apart on the sidewall of the groove.
[0013] This utility model provides a positioning structure for additional reinforcing bars on profiled steel sheets, which has the following advantages: by opening positioning grooves on the spacer, after the spacer is engaged in the bottom groove of the profiled steel sheet, the additional reinforcing bars can be placed directly in the positioning groove. The height of the spacer itself can ensure the gap between the additional reinforcing bars and the bottom groove of the profiled steel sheet, preventing the reinforcing bars from directly contacting the profiled steel sheet after the concrete is poured. Since the length of the spacer is adapted to the width of the bottom groove, it can ensure that the positions of the additional reinforcing bars in the same bottom groove of the profiled steel sheet correspond.
[0014] Furthermore, the pad block is provided with binding grooves, with the openings at both ends of the binding grooves located on both sides of the positioning groove. When the additional reinforcing bar is placed in the positioning groove on the pad block, the additional reinforcing bar and the pad block can be fixedly connected by passing the binding wire through the binding groove, which further ensures the stability of the position of the additional reinforcing bar in the subsequent concrete layer pouring.
[0015] Furthermore, two sets of positioning grooves are provided to facilitate the splicing of additional reinforcing bars in the extension direction of the profiled steel sheet. The binding wire passing through the binding groove can bind the two spliced additional reinforcing bars together on the same pad, ensuring the stability of the splicing of additional reinforcing bars.
[0016] Furthermore, the positioning groove is a semi-circular arc groove that fits the outer surface of the additional reinforcing steel bar, making it easy to place.
[0017] Furthermore, the cross-section of the pad is an arch bridge structure, which not only provides stable load-bearing capacity but also saves materials compared to conventional pads. The groove at the bottom of the pad allows poured concrete to pass through, making the connection between the pad and the concrete layer more stable.
[0018] Furthermore, the grooves of the pad block are spaced apart with several sets of grouting holes that are open at both ends, so that the poured concrete can fill the grouting holes, further strengthening the stable connection between the pad block and the concrete.
[0019] This utility model provides a positioning structure for additional reinforcing bars on profiled steel sheets. By setting a positioning groove on the top of the pad, it helps to quickly position the additional reinforcing bars on the profiled steel sheet. At the same time, the binding groove on the pad helps to fix and splice the additional reinforcing bars. The groove and grouting hole on the pad help to strengthen the connection strength between the pad and the concrete layer. During the construction of additional reinforcing bars on profiled steel sheets, the fixing and binding efficiency of the additional reinforcing bars is effectively improved, and the construction quality of the concrete pouring layer after the additional reinforcing bars are positioned can be guaranteed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0025] Please see Figures 1 to 3 This utility model provides a technical solution: a positioning structure for additional reinforcing bars on a profiled steel sheet, including a bottom groove 101 set on the profiled steel sheet 1, a plurality of pads 2 set in the bottom groove 101, the pads 2 being perpendicular to the extension direction of the bottom groove 101, and the length of the pads 2 being adapted to the width of the bottom groove 101; a positioning groove 201 is formed on the top of the pads 2, the positioning groove 201 being used to place additional reinforcing bars 3, the direction of the positioning groove 201 being consistent with the extension direction of the bottom groove 101; a binding groove 202 is formed on the pads 2, the binding groove 202... Binding wire 4 is inserted inside to bind and fix the additional reinforcing bar 3 to the pad block 2. The positioning groove 201 can quickly determine the position during the placement of the additional reinforcing bar 3. The height of the pad block 2 itself effectively ensures the distance between the additional reinforcing bar 3 and the bottom groove 101 of the profiled steel sheet 1, avoiding the exposure of the additional reinforcing bar 3 after concrete pouring. After the additional reinforcing bar 3 is placed, the binding groove 202 on the pad block 2 can be used to quickly bind and fix the additional reinforcing bar 3 to the pad block 2, thereby solving the technical problem that the additional reinforcing bar 3 of the profiled steel sheet 1 is not easy to position.
[0026] In this embodiment, as a preferred option, the positioning groove 201 is an arc-shaped groove with a semi-circular cross-section, which is easy to open and can be adapted to the outer surface of the additional reinforcing bar 3; the binding groove 202 is an arc-shaped groove with openings at both ends, which helps the binding wire 4 to pass through the binding groove 202. The binding groove 202 is opened below the positioning groove 201, and the openings at both ends of the binding groove 202 are located on both sides of the positioning groove 201. When the additional reinforcing bar 3 is placed in the positioning groove 201, the binding wire 4 can bind and fix the additional reinforcing bar 3 to the pad block 2 from both sides of the positioning groove 201.
[0027] In this embodiment, as a preferred option, two sets of positioning grooves 201 are provided, and the two sets of positioning grooves 201 are arranged adjacent to each other. The profiled steel sheet 1 itself is used for splicing. Similarly, the additional reinforcing bars 3 need to be spliced and lengthened during use. In order to ensure the positioning stability of the additional reinforcing bars 3, the additional reinforcing bars 3 in the same bottom groove 101 are misaligned during splicing. Then, the binding wire 4 simultaneously binds the two additional reinforcing bars 3 together to the same pad block 2, which effectively ensures the stability of the splicing of the additional reinforcing bars 3.
[0028] In this embodiment, as a preferred option, the cross-section of the pad block 2 is arch-shaped, and the bottom of the pad block 2 is provided with a groove 203, which can fill the space of the groove 203 when the concrete is poured. Several sets of vertically and horizontally permeable grouting holes 204 are opened at intervals on the side wall of the groove 203, which can also be filled into the grouting holes 204 when the concrete is poured, further ensuring that the pad block 2 and the poured concrete layer are connected as a whole.
[0029] In this invention, the working steps of the device are as follows:
[0030] 1. Several pads 2 are spaced apart and placed in the bottom groove 101 of the profiled steel sheet 1;
[0031] 2. Place the additional reinforcing bar 3 into the positioning groove 201 of the pad block 2;
[0032] 3. The additional steel bars 3 are fixed to the pad block 2 by passing the binding wire 4 through the binding groove 202. At the splicing position of the additional steel bars 3 in the same bottom groove 101, the two additional steel bars 3 are tied to the same pad block 2 at the same time using the binding wire 4.
[0033] 4. Pour concrete to completely fill the bottom groove 101 space of the profiled steel sheet 1, including the bottom groove 203 of the pad block 2 and the internal space of the grouting hole 204.
[0034] This utility model has the following advantages: First, the positioning groove 201 on the pad 2 can improve the placement efficiency of the additional reinforcing bar 3, and the binding groove 202 on the pad 2 can improve the fixing efficiency of the additional reinforcing bar 3, which helps to improve the construction efficiency of the additional reinforcing bar 3 of the profiled steel sheet 1; Second, the groove 203 at the bottom of the pad 2 and the grouting hole 204 help to strengthen the connection between the pad 2 and the poured concrete layer, making the pad 2 more firmly connected to the profiled steel sheet 1 into a whole, thus improving the construction quality of the profiled steel sheet 1; Third, the pad 2 has a simple structure and can be prefabricated in advance according to the specifications of the profiled steel sheet 1, which helps to save construction time and has strong practicality.
