Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a rebar positioning device for the main structural columns of a building. Background Technology

[0002] In the construction of building projects, columns are important load-bearing components of the main structure. The positioning of horizontal steel bars is particularly critical. It is necessary to strictly control the spacing, height and welding point position between them and vertical steel bars. Compared with vertical steel bars, which can usually be positioned by attaching them to the formwork, horizontal steel bars are suspended in the air and lack direct support and fixed benchmarks. It is difficult for construction workers to accurately control their height and position in actual operation.

[0003] Currently, the positioning of transverse reinforcing bars is still mainly done manually. Construction workers usually use a ruler measurement method, with multiple people working together to lift a transverse reinforcing bar manually and position and weld it according to the manually marked position. This method has the problems of cumbersome operation and low positioning efficiency. At the same time, it is greatly affected by human experience and construction environment, making it difficult to maintain the consistency and accuracy of the position of each transverse reinforcing bar. This often results in phenomena such as welding point misalignment, non-level reinforcing bars, or uneven spacing.

[0004] Therefore, there is an urgent need for a rebar positioning device for the main structural columns of buildings to solve the above-mentioned technical defects. Utility Model Content

[0005] The purpose of this utility model is to provide a rebar positioning device for the main structural columns of a building, so as to solve the problems of difficulty in unifying the rebar positioning height, large error, and cumbersome operation mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rebar positioning device for the main structural column of a building, comprising a vertical frame and a fixing plate. The fixing plate is embedded in the vertical frame. A guide rod is welded to the left side of the fixing plate along its height direction. Multiple sets of positioning devices are sleeved on the outside of the guide rod. A fixing plate is welded to the right side of each set of positioning devices. A locking bolt is fixedly connected between the positioning device and the fixing plate. A positioning plate is fixedly connected to the left side inside the positioning device. An installation screw is fixedly connected between the positioning plate and the positioning device. A positioning groove is opened in the positioning plate, and a gasket is adhered to the inner wall of the positioning groove.

[0007] As a further technical solution of this utility model, a rack is machined on the right side wall of the positioner, and a gear is installed at a corresponding position inside the fixing plate. The gear meshes with the rack, and a throttle is installed at the fixing plate and fixedly connected to the gear shaft.

[0008] As a further technical solution of this utility model, the positioning groove is a "U"-shaped blind groove, and the positioning groove can be removed from the positioner by mounting screws.

[0009] As a further technical solution of this utility model, a sliding sleeve is welded inside the positioner, and the positioner moves outside the guide rod by being sleeved on the sliding sleeve.

[0010] As a further technical solution of this utility model, the right wall edge of the fixing plate is machined with scales, and the positioning device adjusts the spacing through the fixing piece.

[0011] As a further technical solution of this utility model, a connecting seat is fixedly connected to the bottom end of the vertical frame, an extension rod is fixedly connected to the bottom end of the connecting seat, and a connecting bolt is fixedly connected between the extension rod and the connecting seat.

[0012] As a further technical solution of this utility model, the extension rod is sleeved with a support foot, and the extension rod and the support foot are fixedly connected by a height adjustment bolt.

[0013] As a further technical solution of this utility model, the support legs are provided in multiple sets at the bottom of the connecting seat, and the distribution spacing and number of the support legs are set according to the area of ​​the main structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the steel bar positioning device for the main structure column of the building not only realizes the positioning of multiple transverse steel bars of different heights at one time, and realizes the quick adjustment and locking without the use of additional tools, but also achieves stable support and adjustability;

[0015] (1) By setting up a vertical frame, a fixed plate, and a locator, multiple sets of locators move up and down outside the fixed plate via guide rods. The locators and guide rods are slidably connected by a sliding sleeve, which realizes the precise adjustment of the positioning position of steel bars of different heights. The whole device can position multiple transverse steel bars of different heights at one time. It is suitable for steel bar positioning of shear walls, frame columns and other components with strict requirements for symmetrical arrangement. It solves the problems of difficulty in unifying the positioning height of steel bars, large error and cumbersome operation in traditional methods.

After adjustment, the bolt set between the positioning device and the fixing plate is used to lock it, and the adjustment and locking can be completed quickly without the use of additional tools.

[0017] (3) By setting up connecting seats, extension rods, height adjustment bolts and connecting bolts, an adjustable height support structure is formed as a whole.

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.

[0024] Please see Figure 1-4 The present invention provides an embodiment of a steel bar positioning device for the main structural column of a building, comprising a vertical frame 1 and a fixing plate 2. The fixing plate 2 is embedded in the vertical frame 1. A guide rod 7 is welded to the left side of the fixing plate 2 along its height direction. Multiple sets of positioning devices 3 are sleeved on the outside of the guide rod 7. A fixing piece 9 is welded to the right side of each set of positioning devices 3. A locking bolt 5 is fixedly connected between the positioning device 3 and the fixing plate 2. A positioning piece 12 is fixedly connected to the left side inside the positioning device 3. An installation screw 11 is fixedly connected between the positioning piece 12 and the positioning device 3. A positioning groove 13 is opened in the positioning piece 12. A gasket 14 is adhered to the inner wall of the positioning groove 13. The positioning groove 13 is a "U"-shaped blind groove. The positioning groove 13 can be removed from the positioning device 3 by the installation screw 11. A sliding sleeve 17 is welded inside the positioning device 3. The positioning device 3 moves outside the guide rod 7 by being sleeved on the sliding sleeve 17.

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the adjustable spacing between the fixing plate 9 welded to the right side of the locator 3 and the fixing plate 2 allows multiple sets of transverse reinforcing bars to be inserted into different positioning grooves 13 for positioning, thereby ensuring that the welding points of multiple sets of reinforcing bars and vertical reinforcing bars are at the same height. The inner wall of the positioning groove 13 is increased by the gasket 14 to help clamp the reinforcing bars and prevent displacement. The positioning plate 12 can be removed from the locator 3 by the mounting screw 11, which facilitates quick replacement when changing reinforcing bars of different specifications. The entire device can position multiple transverse reinforcing bars of different heights at one time, which is suitable for the positioning of reinforcing bars in shear walls, frame columns and other components with strict requirements for symmetrical arrangement.

[0026] A rack 15 is machined on the right side wall of the positioner 3. A gear 16 is installed at the corresponding position inside the fixing plate 2. The gear 16 meshes with the rack 15. A handle 4 is installed at the fixing plate 9 and is fixedly connected to the shaft of the gear 16. A scale 6 is machined on the edge of the right wall of the fixing plate 2. The positioner 3 adjusts the spacing through the fixing plate 9.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during the positioning process, the operator can manually rotate the handle 4 to drive the gear 16 connected to its shaft to rotate. The gear 16 meshes with the rack 15 set on the right side wall of the positioner 3, so that the positioner 3 can be precisely raised and lowered along the guide rod 7. The right side edge of the fixing plate 2 is provided with a scale 6. By observing the relative position scale 6 of the two sets of positioners 3 in conjunction with the position of the fixing plate 9, the operator can compare and adjust the relative height between multiple positioners 3 according to the scale 6 to ensure symmetrical arrangement and positioning at the same elevation, thereby realizing fine adjustment of the positioning height of the rebar. After the adjustment is completed, it is locked by the locking bolt 5 set between the positioner 3 and the fixing plate 2.

[0028] A connecting seat 8 is fixedly connected to the bottom of the vertical frame 1. An extension rod 18 is fixedly connected to the bottom of the connecting seat 8. A connecting bolt 20 is fixedly connected between the extension rod 18 and the connecting seat 8. A support leg 10 is sleeved on the outside of the extension rod 18. An adjustment bolt 19 is fixedly connected between the extension rod 18 and the support leg 10. Multiple sets of support legs 10 are provided at the bottom of the connecting seat 8. The distribution spacing and number of support legs 10 are set according to the area of ​​the main structure.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, the bottom end of the vertical frame 1 is fixed with a connecting seat 8 by welding. The bottom end of the connecting seat 8 is connected to the extension rod 18 by connecting bolts 20. The extension rod 18 is equipped with adjustable height bolts 19, forming an adjustable height support structure. Multiple support legs 10 are set at the bottom end of the connecting seat 8 and are evenly distributed at intervals, which plays a role in stabilizing and supporting the entire device.

[0030] Working principle: A connecting seat 8 is fixed to the bottom of the vertical frame 1 by welding. The bottom of the connecting seat 8 is connected to the extension rod 18 by connecting bolts 20. An adjustable height bolt 19 is installed on the outside of the extension rod 18, forming an adjustable height support structure. Multiple support legs 10 are set at the bottom of the connecting seat 8 and are evenly distributed to stabilize and support the entire device. During positioning, the operator can manually turn the handle 4 to drive the gear 16 connected to its shaft to rotate. The gear 16 meshes with the rack 15 set on the right side wall of the positioner 3, so that the positioner 3 can be precisely raised and lowered along the guide rod 7. The right edge of the fixing plate 2 is marked with a scale 6. By observing the relative position scale 6 of the two sets of locators 3 in conjunction with the position of the fixing piece 9, the operator can adjust the relative height between multiple locators 3 according to the scale 6 to ensure that they are symmetrically arranged and positioned at the same elevation, thereby achieving fine adjustment of the positioning height of the rebar. After adjustment, the locator 3 is locked by the bolt 5 set between the locator 3 and the fixing plate 2 to ensure that the locator 3 remains stable at the set height position. Multiple sets of transverse rebars are respectively inserted into different positioning slots 13 for positioning, thereby ensuring that the welding point height of multiple sets of rebars and vertical rebars is consistent.
