Description

Technical Field

[0001] The utility model relates to the technical field of drilling and rebar planting construction, in particular to a drilling and rebar planting anti-dropping reinforcement sleeve tool. Background Art

[0002] The construction sequence of drilling and rebar planting is usually horizontal layout → drilling → hole cleaning → glue injection → rebar planting.

[0003] Conventional drilling and rebar planting technology may easily lead to insufficient bonding after planting and loosening of the rebars if the glue is not fully injected or the hole is not cleaned thoroughly during the construction process, which may also lead to extended construction period and increased costs. A drilling and rebar planting anti-detachment reinforcement sleeve tool is needed to improve the stability of drilling and rebar planting. Summary of the invention

[0004] The utility model aims to provide a drilling and embedding reinforcement sleeve to prevent the fall-off of reinforcement sleeves, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A drilling and rebar planting anti-dropout reinforcement sleeve tool is characterized in that it includes a barrel, a horizontal rack, a fixed rack and a friction rack, wherein a plurality of horizontal racks are evenly arranged at both ends of the barrel, and a plurality of fixed racks are evenly arranged in the middle of the horizontal racks; and a plurality of friction racks are arranged inside the barrel.

[0007] Furthermore, the horizontal rack is perpendicular to the axial direction.

[0008] Furthermore, the fixed rack forms an angle with the axial direction.

[0009] Furthermore, the horizontal racks in the radial cross section of the barrel are arranged in a cross shape.

[0010] Furthermore, the fixed racks in the radial cross section of the barrel are arranged in a cross shape.

[0011] Furthermore, the friction rack inside the barrel is arranged opposite to the ribs of the steel bar.

[0012] Furthermore, the depth at which the barrel is installed in the hole is greater than half of the hole depth.

[0013] The utility model has the advantages that: the utility model uses the friction between the rack of the barrel and the concrete structure for installation and fixing, the ribbed steel bar and the sleeve are installed in a slot-type manner, the texture of the ribbed steel bar and the friction rack inside the barrel are set in the opposite direction, the friction is increased, and the stability of drilling and planting steel bars is improved. It ensures that the stability of planting steel bars will not be affected by insufficient glue injection and unclean hole cleaning during drilling and planting, and the operation is simple and the adaptability is strong.

[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 A drilling and rebar planting anti-slip reinforcement sleeve tool, characterized in that it includes a barrel 1, a horizontal rack 2, a fixed rack 3 and a friction rack 4, a plurality of horizontal racks 2 are evenly arranged at both ends of the barrel 1, and a plurality of fixed racks 3 are evenly arranged in the middle of the horizontal racks; a plurality of friction racks 4 are arranged inside the barrel 1; the horizontal racks 2 are perpendicular to the axial direction; the fixed racks 3 are at an angle to the axial direction; the horizontal racks 2 of the barrel 1 are arranged in a "cross" shape in a radial section; the fixed racks 3 of the barrel 1 are arranged in a "cross" shape in a radial section; the friction racks 4 inside the barrel 1 are arranged opposite to the ribs of the steel bars.

[0022] During construction, horizontal marking is carried out at the drilling and reinforcing bar embedding positions of the structural beams, and the drilling is completed and cleaned. After cleaning, the cylinder body 1 is horizontally installed using the horizontal rack 2, and the fixed rack 3 is fixed by friction with the concrete structure. After the anti-slip reinforcement sleeve is installed, glue is injected and the steel bars are implanted. The friction rack 4 is set opposite to the ribs of the implanted steel bars, which increases the friction between the cylinder body friction rack 4 and the ribbed steel bars and improves the stability of the drilling and reinforcing bar embedding.

[0023] In the description of the utility model, it should be noted that the barrel 1 cannot be installed shallowly in the hole, which will reduce the friction area between the ribs of the steel bar and the friction rack 4 and reduce the stability of the embedded steel bar. The depth of the barrel 1 installed in the hole should be greater than half of the hole depth.

[0024] The utility model solves the problem of loosening of the rebars caused by incomplete cleaning of the holes for drilling and embedding rebars and insufficient glue injection, effectively fixes the cylinder body 1 to the concrete structure through the horizontal rack 2 and the fixed rack 3, and embeds the rebars by setting the friction rack 4 inside the cylinder body opposite to the ribs of the steel bars, and then enhances the stability of the implanted steel bars through glue embedding, thereby improving the forming effect of the drilled holes and the safety performance of the embedded rebars.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
