Description

Technical Field

[0001] The present invention relates to the field of construction, and particularly to the field of construction column planting bar positioning construction. Background Art

[0002] Planting bars, also known as implanting bars, are a kind of post-anchoring connection technology for steel bars in the seismic reinforcement project of building structures, which utilizes the locking force of structural adhesive. In building construction, planting bars need to be carried out after the main structure construction is completed to ensure the connection between the construction column and the upper and lower main structures.

[0003] The usual construction method is to position on the first floor beam according to the drawings and specifications, determine the lower end position of the construction column, and carry out operations such as hole opening, hole cleaning, glue injection, and bar insertion; then find the corresponding position at the bottom of the second floor beam by referring to the lower end position, and repeat the operations of hole opening, hole cleaning, glue injection, and bar insertion to determine the upper end position of the construction column. Finally, tie the bundled construction column to the planting bars at the upper and lower ends for tying and lapping.

[0004] However, in this method, when tying and lapping the construction column with the upper planting bar, situations such as the unequal position of the upper planting bar and the lower planting bar, and the insufficient tying and lapping of the upper planting bar and the construction column steel bars often occur. Summary of the Invention

[0005] An object of the present invention is to provide a construction column planting bar positioning device, which can ensure the consistent corresponding positions of the planting bars facing each other and improve the positioning accuracy.

[0006] The construction column planting bar positioning device for achieving the above object is used to position the first-end planting bar. The second-end planting bar faces the first-end planting bar and is respectively fixed on the opposite second end face and the first end face. The device includes a fixing device, a guide rail rod, and a laser emitter. The fixing device is fixed on the second end face and is used to position the second-end planting bar; the guide rail rod is arranged on the fixing device; the laser emitter is movably arranged on the guide rail rod, one end is used to abut against the end face of the second-end planting bar in a centered manner, and the other end is used to mark a point position on the first end face.

[0007] In one or more embodiments, the fixing device includes a U-shaped outer shell with a cavity, and the U-shaped outer shell is fixed on the second end face.

[0008] In one or more embodiments, the fixing device further includes a plurality of lower adjustable fixing rods and large abutting pieces located at the ends of the lower adjustable fixing rods. The lower adjustable fixing rods penetrate through the U-shaped outer shell, and each of the large abutting pieces is used to enclose a chamber to limit the second-end planting bar in the chamber.

[0009] In one or more embodiments, the lower adjustable fixing rod is a screw rod with a first fixing nut thereon.

[0010] In one or more embodiments, the fixing device further includes a plurality of upper adjustable fixing rods and small abutting pieces located at the ends of the lower adjustable fixing rods. The upper adjustable fixing rods penetrate through the U-shaped housing, and the small abutting pieces are used to abut against the second-end rebar implantation.

[0011] In one or more embodiments, the upper adjustable fixing rod is a screw rod with a second fixing nut thereon.

[0012] In one or more embodiments, the guide rail rod is fixedly arranged on the upper adjustable fixing rod and is perpendicular to the upper adjustable fixing rod.

[0013] In one or more embodiments, the guide rail rod includes a hollow cavity, the laser emitter is arranged on an adjusting rod passing through the hollow cavity, and a fixing nut is arranged on the adjusting rod.

[0014] Another object of the present invention is to provide a method for positioning the rebar implantation of a construction column. This method uses the above-mentioned rebar implantation positioning device for a construction column and includes the following steps: taking the first end face as the positioning face, fixing the second-end rebar implantation on the second end face; fixing the fixing device on the second end face; adjusting the position of the laser emitter on the guide rail rod until the laser emitter abuts against the top surface of the second-end rebar implantation in a centered manner; turning on the laser emitter so that the laser beam shoots onto the positioning face to obtain a laser marked point position.

[0015] In one or more embodiments, the fixing device includes a plurality of lower adjustable fixing rods, large abutting pieces located at the ends of the lower adjustable fixing rods, a plurality of upper adjustable fixing rods, and small abutting pieces located at the ends of the upper adjustable fixing rods. First, adjust the large abutting pieces and the small abutting pieces to adjust the position of the second-end rebar implantation, and then adjust the position of the laser emitter on the guide rail rod.

[0016] The above-mentioned rebar implantation positioning device and method for a construction column can ensure that the positions of the upper and lower rebar implantations are consistent. By using the laser emitter to first center and position on the already fixed rebar implantation, marking points on the other end face on the basis of initially positioning one end, so as to mark point positions on the side that needs to be positioned. Subsequently, operations such as hole opening, hole cleaning, glue injection, and rebar insertion are carried out according to these point positions, which can increase the accurate docking probability of the upper and lower rebar implantations, thereby improving the construction quality and construction efficiency of the rebar implantation of the construction column and increasing the one-time acceptance pass rate of the on-site construction column.

[0029] The present invention will be further described below in conjunction with specific embodiments and the accompanying drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from this description. Those skilled in the art can make similar generalizations and deductions according to the actual application situation without departing from the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0030] It should be noted that these and subsequent other drawings are only examples, and they are not drawn according to the condition of equal proportion, and should not be used to limit the actual claimed protection scope of the present invention.

[0031] During the construction process of post-inserted bars, situations often occur where the position of the upper post-inserted bar is not equal to that of the lower post-inserted bar, and the binding and lapping of the upper post-inserted bar and the construction column steel bars are not in place. The post-inserted bar positioning device for construction columns described in the present invention is used to make the positions of the post-inserted bars on the upper and lower sides of the construction column more accurate, to avoid situations such as the inequality of the upper and lower post-inserted bars during the post-inserted bar process, the inability to bind and lap the construction column steel bars and the post-inserted bars, and the low first acceptance rate and qualified rate of the construction column steel bars.

[0032] Refer to Figure 1 As shown, the construction column reinforcement implant positioning device is used to position the first-end reinforcement implant, where the first-end reinforcement implant refers to either the upper-end reinforcement implant or the lower-end reinforcement implant.

[0033] For ease of understanding, in the Figure 1 embodiment shown, the first-end reinforcement implant 51 refers to the upper-end reinforcement implant, and the second-end reinforcement implant 52 refers to the lower-end reinforcement implant. The second-end reinforcement implant 52 and the first-end reinforcement implant 51 face each other and are respectively fixed on the opposite second end face 200 and first end face 100.

[0034] The first end face 100 and the second end face 200 can be provided by the upper beam and the lower beam respectively.

[0035] If you want to position the first-end reinforcement implant 51 on the first end face 100, the second-end reinforcement implant 52 needs to be fixed on the second end face 200, such as through operations like positioning, drilling, hole cleaning, gluing, and inserting the reinforcement implant, and has been fixed in the concrete of the second end face 200.

[0036] The construction column reinforcement implant positioning device includes a fixing device 10, a guide rail rod 18, and a laser emitter 20.

[0037] The fixing device 10 is fixed on the second end face 200 and is used to position the second-end reinforcement implant 52. The guide rail rod 18 is arranged on the fixing device 10, and the laser emitter 20 is movably arranged on the guide rail rod 18. One end is used to abut against the end face 521 of the second-end reinforcement implant 52 in a centered manner, and the other end is used to mark a point A on the first end face 100 for the positioning of the first-end reinforcement implant 51, as Figure 1 and Figure 8 shown.

[0038] Next, the fixing device 10 will be introduced in conjunction with Figures 2 to 11 this.

[0039] In some embodiments, the fixing device 10 includes a U-shaped outer shell 11 with a cavity, and the U-shaped outer shell 11 is fixed on the second end face 200. For example, the U-shaped outer shell 11 can be a wooden hollow square column outer shell, made of waste formwork, with dimensions of 300mm * 300mm * 700mm. The U-shaped outer shell 11 surrounds the second-end reinforcement implant 52 and simultaneously serves to position the second-end reinforcement implant 52 and as a support carrier for other components of the construction column reinforcement implant positioning device.

[0040] Furthermore, the fixing device 10 further includes a plurality of lower adjustable fixing rods 13 and large sheet pieces 15 located at the ends of the lower adjustable fixing rods 13. The lower adjustable fixing rods 13 penetrate through the U-shaped outer shell 11, and each large sheet piece 15 is used to enclose a chamber B to confine the second-end reinforcement implant 52 within the chamber B, as Figure 2 shown.

[0041] The lower adjustable fixing rod 13 is preferably a screw rod, with a first fixing nut 14 thereon. The first fixing nut 14 is used to position the lower adjustable fixing rod 13 in the U-shaped housing 11, and thus fix the protruding position of the large abutting piece 15. Specifically, with reference to Figure 10 and Figure 11 it is understood that the lower adjustable fixing rod 13 is used in combination with the first nut 14 and the large abutting piece 15. Its length is preferably 200 mm and its diameter is preferably 8 mm. The large abutting piece 15 preferably has dimensions of 100 mm * 100 mm * 10 mm. Rotate the lower adjustable fixing rod 13 and push it towards the second-end implanted bar 52. In cooperation with the first fixing nut 14, until the large abutting piece 15 abuts against the second-end implanted bar 52, as Figure 11 shown, the second-end implanted bar 52 is limited within the chamber B to achieve the effect of fixing the overall device and positioning the implanted bar.

[0042] Furthermore, referring back to Figure 1 and Figure 2 , the fixing device 10 further includes a plurality of upper adjustable fixing rods 12 and small abutting pieces 16 located at the ends of the lower adjustable fixing rods 12. The upper adjustable fixing rods 12 penetrate through the U-shaped housing 11 and are located above the lower adjustable fixing rods 13. The small abutting pieces 16 are used to abut against the second-end implanted bar 52.

[0043] The upper adjustable fixing rod 12 is preferably a screw rod, with a second fixing nut 17 thereon. With reference to Figure 3 and Figure 4 it is understood that similar to the movement of the lower adjustable fixing rod 13 and the large abutting piece 15, rotate the upper adjustable fixing rod 12. In cooperation with the second fixing nut 17, until the small abutting piece 16 abuts against the second-end implanted bar 52. At this time, by adjusting the screwing-out distance of the upper adjustable fixing rod 12, the position of the second-end implanted bar 52 can be finely adjusted.

[0044] The upper adjustable fixing rod 12 preferably has a length of 200 mm and a diameter of preferably 8 mm.

[0045] The small abutting piece 16 preferably has dimensions of 50 mm * 50 mm * 10 mm. Its function is to abut against the lower second-end implanted bar 52, preferably abutting against the position of the second-end implanted bar 52 close to the end 521, so as to finely adjust the second-end implanted bar 52. Since the position of the steel bar will deviate during the manual bar implantation process, therefore, pushing the upper adjustable fixing rod 12 and the small abutting piece 16 can initially adjust the position of the second-end implanted bar 52 to the expected position.

[0046] Continuing to refer to Figure 3 and Figure 4As shown, the guide rail rod 18 is fixedly arranged on the upper adjustable fixing rod 12 and is perpendicular to the upper adjustable fixing rod 12. The guide rail rod 18 preferably has a length of 300 mm and a diameter of 6 mm. The guide rail rod 18 includes a hollow cavity 181, and the laser emitter 20 is arranged on the adjusting rod 21 passing through the hollow cavity 181, as Figures 5 to 7 shown. A third fixing nut 23 is provided on the adjusting rod 21 to fix the position of the laser emitter 20 on the guide rail rod 18.

[0047] The hollow cavity 181 of the guide rail rod 18 can allow the laser emitter 20 to move up and down. The laser emitter 20 is perpendicular to the adjusting rod 21 and can be fixedly connected by means such as structural adhesive.

[0048] The first-end implanted bars 52 generally include multiple implanted bar steels. Then, multiple guide rail rods 18, 18' are arranged circumferentially along the first-end implanted bars 52, and multiple laser emitters 20, 20' are used to respectively locate the end faces 521 of the multiple implanted bar steels, as Figure 2 and Figure 9 shown.

[0049] The laser emitter 20 can be an infrared laser emitter or other types of laser emitters. Its function is to find and locate points on the first end face 100 where the first-end implanted bars 51 are located. Rotate the third fixing nut 23. Each infrared laser emitter moves up and down in the hollow cavity 181 and finally fixes the laser emitter 20 above the end face 521 of the second-end implanted bars 52. Subsequently, adjust the second fixing nut 17 to control the upper adjustable fixing rod 12 to drive the small abutting piece 16 to finely adjust the second-end implanted bars 52 until the bottom of the infrared laser emitter 20 is centered with the top of the second-end implanted bars 52.

[0050] After completion, turn on the infrared laser emitter. Along the traction of the laser beam 22, a marked point A is formed on the first end face 100, and the position of the upper-end implanted bars of the second-layer beam bottom structural column is determined, as Figure 8 shown.

[0051] Combined with the introduction of the above structural column implanted bar positioning device, a method for the structural column implanted bar positioning device can also be understood. The method includes the following steps.

[0052] Take the first end face 100 as the positioning surface and fix the second-end implanted bars 52 on the second end face 200. According to the requirements of the design drawing, clean the area around the position of the second-end implanted bars to be fixed. The length of the second-end implanted bar steel is L. It can be understood that in other embodiments, if the second end face 200 is taken as the positioning surface and downward positioning is to be realized, the first-end implanted bars 51 are fixed on the first end face 100.

[0053] Subsequently, the fixing device 10 is fixed on the second end face 200. Specifically, the U-shaped housing 11 of the fixing device 10 is fixed on the second end face 200, and the lower adjustable fixing rod 13 and the large abutting piece 15 are adjusted first to fix the U-shaped housing 11 to the post-inserted steel bar, so as to position the post-inserted steel bar 52 at the second end.

[0054] As Figure 2 shown, rotate the first fixing nut 14 so that the top end abutting pieces of the lower 4 adjustable fixing rods abut against the post-inserted steel bar to fix the entire device, ensuring that there is no large position deviation during the implementation of the positioning device. Then adjust the upper adjustable fixing rod 12 and the small abutting piece 16 to finely adjust the position of the post-inserted steel bar 52 at the second end, solve the problem of position deviation of the post-inserted steel bar during the manual post-insertion process, and play a role in centering the bottom of the infrared laser emitter with the top end face of the post-inserted steel bar.

[0055] Adjust the position of the laser emitter 20 on the guide rail rod 18 until the laser emitter 20 abuts against the top surface 521 of the post-inserted steel bar 52 in a centered manner.

[0056] Turn on the laser emitter 20 so that the laser beam 22 is emitted onto the positioning surface, that is, onto the first end face 100 to be positioned, to obtain the laser marking point A.

[0057] Thus, on the premise that one end of the post-inserted steel bar has been fixed, the above-mentioned device uses the laser aligned with this end of the post-inserted steel bar to obtain the laser marking point on the positioning surface, thereby accurately positioning the position of the post-inserted steel bar at the other end, improving the accuracy of the butt joint of the post-inserted steel bars at both ends, making the position of the post-inserted steel bar at the upper part of the structural column more accurate, effectively avoiding the occurrence of dislocation, reducing the operation difficulty and the number of reworks, reducing the quality and safety risks caused by improper steel bar binding in the later stage of the structural column, improving the on-site construction efficiency and construction quality, and at the same time ensuring the future structural safety.
