Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar positioning in construction, and in particular relates to a steel bar positioning mechanism in construction. Background Art

[0002] During the pouring of reinforced concrete components, multiple locating steel bars are required. These bars are used to secure the position of the reinforcement skeleton to ensure structural requirements such as the component's cover thickness and clearance. The location of these locating steel bars is typically determined manually by measuring and drawing lines according to the blueprint. However, with the increasing demand for standardized construction, manual measurement and drawing methods have resulted in significant errors and are no longer sufficient for construction.

[0003] A Chinese patent with authorization announcement number "CN220133277U" discloses a steel bar positioning structure for construction, which consists of a positioning block and multiple positioning holes. The positioning structure is installed in the construction area through a support plate and a support column. The support column can move up and down along the sleeve to facilitate the adjustment of the use height of the support plate and the positioning block. The adjustment mechanism adjusts the use position of the positioning hole by squeezing the movable plate to ensure that the positioning hole corresponds to the installation position of the steel bar. Inserting multiple steel bars into the positioning holes in sequence can effectively prevent the steel bars from being skewed. After the steel bars are bundled, the two movable plates move away from each other and out of contact with the steel bars. The positioning structure is easy to remove and move, ensuring the accuracy of the steel bar installation positioning.

[0004] However, the above positioning structure is large in size and inconvenient to install and use; and the spacing between multiple steel bars is determined by the elastic force adjustment of the elastic member. The deformation of the elastic member is unstable, resulting in unstable steel bar positioning accuracy, which cannot meet standardized construction requirements. Utility Model Content

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] The directional terms used in the detailed description are intended solely to facilitate understanding of the technical solutions described herein by those skilled in the art based on the visual orientation shown in the accompanying drawings. Unless otherwise specified or limited, the terms "dispose," "install," and "connect" are to be interpreted broadly, and those skilled in the art will understand their specific meanings in this utility model based on the specific circumstances.

[0034] like Figures 1 to 12As shown, the construction steel bar positioning mechanism includes an external support mechanism 2, which mainly protects the internal structure of the equipment and fixes the driving components. The external support mechanism 2 includes a protective shell 201, a carrying seat is fixed on the upper end of the protective shell 201, and a handle hole 2011 is provided on the carrying seat, through which the present invention can be easily lifted, making it more convenient to use; a lifting slot is provided on the protective shell 201, and the internal two sides of the internal protective shell 201 in the external support mechanism 2 are respectively fixedly connected with the internal support mechanism 1, and the two groups of internal support mechanisms 1 are symmetrically arranged, and the two groups of internal support mechanisms 1 are slidably connected with the sliding adjustment component 3, and at least two parallel guide rods 4 are fixedly connected between the two groups of internal support mechanisms 1. In this embodiment, there are four guide rods 4, and a plurality of spacing adjustment mechanisms 5 are slidably connected on the four guide rods 4. A positioning and fixing mechanism 6 is fixedly connected to the spacing adjustment mechanism 5. The positioning and fixing mechanism 6 is used to clamp and fix the steel bars 7. The sliding direction of the spacing adjustment mechanism 5 is perpendicular to the sliding direction of the sliding adjustment component 3. Taking the installation of the longitudinal positioning steel bars as an example, the positioning steel bars are vertically arranged. At this time, the sliding adjustment component 3 slides up and down, and the spacing adjustment mechanism 5 slides left and right.

[0035] like Figure 11 As shown, the internal support mechanism 1 includes a support column 101, which is vertically arranged. A sliding groove 102 and at least two mounting holes 103 are respectively opened on the opposite sides of the two support columns 101. The number of mounting holes 103 corresponds to the number of guide rods 4. Both ends of the guide rods 4 are fixedly arranged in the corresponding mounting holes 103, and the sliding groove 102 is arranged on the inner side of the mounting hole 103, that is, the sliding groove 102 is arranged on the side close to the external support mechanism 2.

[0036] like Figure 3 As shown, a driving assembly for driving the sliding adjustment assembly 3 to slide is provided on the back of the external support mechanism 2, and the driving assembly includes a threaded rod 204 rotatably connected to the protective shell 201. Specifically, both ends of the threaded rod 204 are optical axis structures, and the optical axis structures at both ends are connected to the protective shell 201 through bearings and bearing seats 203. The bearing seat 203 is fixed on the protective shell 201, and the top of the threaded rod 204 is fixedly connected to the handwheel 202.

[0037] like Figures 8 to 10As shown, the sliding adjustment assembly 3 is provided with a plurality of spacing adjustment slots 303 distributed in a scattered manner. Specifically, the sliding adjustment assembly 3 includes a sliding plate 304, both sides of which are slidably arranged in the sliding slot 102. A plurality of spacing adjustment slots 303 are provided on the sliding plate 304 in a scattered manner. A fixed block 302 is fixedly connected to the top of the sliding plate 304. A reinforcing rib is welded between the fixed block 302 and the sliding plate 304. The reinforcing rib improves the connection strength between the fixed block 302 and the sliding plate 304. An adjusting nut 301 is fixedly connected to the end of the fixed block 302 away from the sliding plate 304. The adjusting nut 301 is rotatably connected to the threaded rod 204 in the drive assembly. During installation, the fixed block 302 passes through the lifting slot and moves within the lifting slot. When the handwheel 202 is turned, the threaded rod 204 rotates accordingly, thereby driving the adjusting nut 301 to move up and down on the threaded rod 204. The adjusting nut 301 drives the sliding plate 304 to move synchronously through the fixed block 302.

[0038] In the present invention, there are nine spacing adjustment slots 303, with the centerline of the middle spacing adjustment slot 303 pointing vertically downward. The upper end of the spacing adjustment slot 303 is the slot top 3031, and the horizontal spacing between the centers of the slot tops 3031 of adjacent spacing adjustment slots 303 is L1. The lower end of the spacing adjustment slot 303 is the slot bottom 3032, and the horizontal spacing between the centers of the slot bottoms 3032 of adjacent spacing adjustment slots 303 is L2, with L2 being greater than L1. In this manner, the spacing adjustment slots 303 can assist multiple spacing adjustment mechanisms 5 in performing equal spacing adjustments.

[0039] like Figure 4 As shown, the spacing adjustment mechanism 5 includes a spacing adjustment plate 501. In this embodiment, there are four guide rods 4, so four holes are opened on the spacing adjustment plate 501. The guide rods 4 pass through the holes on the spacing adjustment plate 501. Limiting sleeves 504 are fixed on both sides of the hole in the spacing adjustment plate 501. The limiting sleeves 504 can assist in limiting the minimum spacing between adjacent spacing adjustment mechanisms 5. The U-shaped fixing seat 601 is fixedly connected to the spacing adjustment plate 501. The spacing adjustment mechanism 5 is provided with a sliding guide block 502 that slides with the spacing adjustment slot 303. The sliding guide block 502 is arranged on the side away from the U-shaped fixing seat 601. The sliding guide block 502 is fixedly connected to the sliding guide block 502 to prevent it from disengaging from the spacing adjustment slot 303.

[0040] like Figure 2 As shown, the positioning and fixing mechanisms 6 in adjacent spacing adjustment mechanisms 5 are staggered, which can facilitate the positioning and fixing mechanisms 6 to fix and loosen the steel bars 7 when the spacing between adjacent spacing adjustment mechanisms 5 is small.

[0041] like Figures 5 to 7As shown, the positioning and fixing mechanism 6 includes a U-shaped fixing seat 601, an inner bottom plate 6011 is provided inside the U-shaped fixing seat 601, and side plates 1 6012 and 2 6013 are fixed on both sides of the inner bottom plate 6011 respectively. A T-shaped slide groove 608 is provided in the inner bottom plate 6011, and a clamping plate 602 for fixing steel bars is slidably connected to the side plate 2 6013 through a guide column 605. There are two guide columns 605, and both guide columns 605 pass through the side plate 2 6013 and slide with the side plate 2 6013. A spring 606 is sleeved on the guide column 605, and the spring 606 is a tension spring. One end of the spring 606 is fixedly connected to the clamping plate 602, and the other end of the spring 606 is fixedly connected to the side plate 2 6013. A rectangular slider 602 that matches the end surface of the inner bottom plate 6011 is fixed on the clamping plate 602. 2. A T-shaped slider 6021 that matches the T-shaped slide groove 608 is fixed on the rectangular slider 6022. The rectangular slider 6022 and the T-shaped slider 6021 greatly improve the clamping reliability of the clamping plate 602 and prevent the clamping plate 602 from being deformed. A rectangular groove 609 for the rectangular slider 6022 to pass through is provided on the side plate 2 6013. A threaded adjustment rod 604 for supporting the clamping plate 602 is threadedly connected to the side plate 2 6013. The end of the threaded adjustment rod 604 away from the clamping plate 602 is fixedly connected to the adjusting wheel 607. Rotating the adjusting wheel 607 causes the threaded adjustment rod 604 to rotate accordingly to tighten the clamping plate 602. An anti-slip groove 603 is provided on the side of the clamping plate 602 opposite to the side plate 1 6012. The anti-slip groove 603 is used to prevent the steel bar 7 from moving during the fixing process.

[0042] In this embodiment, there are nine spacing adjustment slots 303 and nine spacing adjustment mechanisms 5. The central spacing adjustment slot 303 is a vertical slot. Therefore, during adjustment, the central spacing adjustment mechanism 5 remains stationary. During manufacture, a scale is provided on the upper surface of the protective housing 201, using the side plate 1 6012 on the positioning and fixing mechanism 6 of the central spacing adjustment mechanism 5 as a reference to mark the spacing between adjacent spacing adjustment mechanisms 5.

[0043] like Figure 12As shown, during construction, the required rebar spacing is adjusted in advance according to the drawing requirements. The adjustment method is as follows: Turn the handwheel 202, which drives the threaded rod 204 to rotate. The threaded rod 204 drives the adjustment nut 301 to move. The adjustment nut 301 further drives the sliding plate 304 to move synchronously. During the up and down movement of the sliding plate 304, the spacing adjustment slot 303 drives the sliding guide block 502 in the spacing adjustment mechanism 5 to move. Under the lateral guidance of the guide rod 4, the spacing adjustment mechanism 5 can only move horizontally, thereby changing the spacing between adjacent spacing adjustment mechanisms 5, thereby completing the spacing adjustment. At the same time, during the rotation process of the threaded rod 204, the self-locking of the adjustment nut 301 can prevent the threaded rod 204 from reversing. Before installing the steel bar 7, the adjusting wheel 607 in the positioning and fixing mechanism 6 is rotated to move the threaded adjusting rod 604 away from the side plate 1 6012. The clamping plate 602, under the tension of the spring 606, moves accordingly, increasing the distance between the clamping plate 602 and the side plate 1 6012. This allows for positioning of steel bars 7 of various thicknesses. During use, the steel bar 7 is placed between the side plate 1 6012 and the clamping plate 602 in the two sets of positioning and fixing mechanisms 6, respectively. The adjusting wheel 607 is then rotated to force the threaded adjusting rod 604 against the clamping plate 602 and move it toward the side plate 1 6012 until the clamping plate 602 clamps the steel bar. The two sets of positioning and fixing mechanisms 6 provide for more accurate vertical positioning of the steel bars. Even if the spacing between multiple steel bars 7 is not suitable after installation, the hand wheel 202 can be used to fine-tune the position. This greatly improves the flexibility and standardization of construction, makes it more convenient to use, and ensures more accurate positioning of the steel bars 7.

[0044] After the steel bar 7 is positioned, it is tied and fixed. After all the tying and fixing are completed, the adjusting wheel 607 is slightly turned to allow the steel bar 7 to be detached. This makes disassembly easy and improves construction efficiency.

[0045] Finally, although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
