Description
Technical Field
The invention relates to an embossing type bar-planting anchor head device, and belongs to the technical field of civil engineering construction.
Background
The bar planting technology is characterized in that the specification, the number and the position of reinforcing steel bars are determined on concrete members needing to be connected according to the stress requirements of structures, and the reinforcing steel bars and the concrete are bonded together through structural adhesive after drilling, cleaning holes and injecting bar planting adhesive into the members and inserting required reinforcing steel bars, so that the purposes of coaction and integral stress are achieved.
The bar planting is a post-anchoring connection method for planting ribbed steel bars or full-thread screws in concrete base materials by using special organic or inorganic adhesives. The wall of the concrete hole and the outer surface of the steel bar form firm bonding anchoring force by bonding the anchoring force through the structural adhesive, and the steel bar pullout force and the shearing force are resisted by the bonding anchoring force. The bar planting technology is simple and rapid in construction and is more and more widely applied.
The embedded bars are divided into three types according to the importance: (1) important structural members and non-structural members of life engineering; (2) a general structural member; and (3) non-structural members of non-lifeline engineering. The embedded steel bars of the structural components are mainly applied to the connection of new and old components for structural reinforcement, and the embedded steel bars of the most common filler wall masonry belong to the embedded steel bars of non-structural components.
Because it is fixed by chemical bonding, it not only can not produce expansion damage to base material, but also has reinforcing action to structure. The construction is simple, convenient and rapid, safe and meets the requirement of environmental protection. The method is the most effective method for changing, adding and reinforcing the reinforced concrete structure in the building engineering, and can be implanted with common steel bars and bolt type anchor bars. The reinforcing device is suitable for reinforcing reserved steel bars of various building structures, such as additional construction and change, reinforcing beams, column heads, floor slabs, shear walls and the like, anchoring the reserved steel bars, and anchoring screw rods of various steel structures, supports and the like. Such as: the remedy of missing reinforcing steel bars or the deviation of the reinforcing steel bars from the designed position in the construction process is realized, the reinforcing steel bars for reinforcing the cross section are increased by the components, the span of the upper structure is expanded, the beam and the column are lengthened through jacking, the storey-adding column of a house and the embedded steel bars of a shear wall are additionally arranged on a high-rise building, and the like.
However, the existing bar-planting technology has many problems, such as difficult drilling, difficult drilling when the structural steel bar is dense or the drilling is required to be deep, difficult guarantee of not touching the steel bar by operators, and if the steel bar is drilled, firstly, the structure may be damaged, and secondly, accidents may be caused by the difficult drilling operation. In addition, the anchoring length of the steel bar is difficult to determine; the common anchoring is difficult to resist the earthquake force; the use of anchoring materials has more limitations; the connection of the steel bars is more limited; the anchoring part has more limits and the like.

The bottom of each steel wire is provided with a pier rivet head, the top of each steel wire is properly bent, the orientation of each steel wire is different, but the overall range of each steel wire does not exceed the range of the outer diameter of the nut, so that the steel wire can be smoothly inserted into a drilled hole during bar planting. The steel wire used, while having sufficient strength, should also be bent to produce an embossing effect after being inserted into the hole bottom and being hammered.
When the diameter of the ribbed steel bar is small, the diameter of the cap-shaped screw cap is smaller (for example, less than 6mm) and a plurality of wire implanting holes cannot be processed, the cap-shaped screw cap can be changed into a flat-top cap nut, only one wire implanting hole is arranged on the flat-top cap nut, a steel wire bundle is implanted into the hole, all implanted steel wires share one pier riveting head, after the steel wire bundle is connected with the wire implanting hole in an interference connection mode, the steel wire bundle is separated from the outer end part of the screw cap one by one, the upper parts of the steel wires are properly bent and are different in orientation, and therefore the steel wires can be conveniently embossed into a cluster.
The invention has the advantages that only one end of the ribbed steel bar is turned into a screw, and the screw is screwed into the cap-shaped nut which is implanted with the steel wire in advance, the existing steel bar implanting construction method is not changed, only the rod body with the steel wire anchor head is inserted to the bottom of the hole, the external end of the steel bar implanting body is hammered by an iron hammer, and the rod body is embedded and firmly fixed in the hole by utilizing the stress deformation of the steel wire. The invention solves the problem of difficult construction due to over-deep drilling depth during bar planting, solves the problem that the stress of the bar body is totally dependent on the performance and quality of bar planting glue, and improves the stress performance of the bar body for bar planting to the maximum extent.
