Abstract
The invention discloses a steel wire mesh cylinder with a preformed hole and a method for carrying out steel bar connection. The traditional anchoring of a steel bar is carried out by using method for pre-embedding a solid mold core, which needs a large quantity of mold cores. In the invention, the steel wire mesh cylinder with the preformed hole includes a steel wire mesh cylinder (1), wherein one end of the steel wire mesh cylinder is opened while the other end is enclosed; a spiral groove (2) is arranged outside the cylinder; the steel wire mesh cylinder is provided with an air outlet hole (4) which is communicated with the inner side of the cylinder and close to the enclosed end; the steel wire mesh cylinder is provided with a grouting hole (3) which is communicated with the inner side of the cylinder and close to the opening end; and the opening of the steel wire mesh cylinder is pre-embedded outwards in the inner side of precast concretes (5). When being used, the steel wire mesh cylinder with an outward opening is pre-embedded inside the precast concretes, the steel bar is inserted into the opening end and blocked, the grouting is carried out on a grouting hole, and the air outlet hole naturally exhausts the air so as to anchor the steel bar. The invention is used for carrying out steel bar anchoring and lap joint among structural members of the precast concretes.
Description
Technical field:
The present invention relates to a kind of reinforcing bar anchoring and overlap joint method of attachment of precast concrete member, be specifically related to a kind of method that has the gauze wire cloth cylinder of preformed hole and carry out the reinforcing bar connection.
Background technology:
In precast concrete; Preformed hole grouting bar splicing method of attachment is adopted in the anchor connection of reinforcing bar more; But traditional preformed hole method adopts the pre-buried method of core rod of entity more, because number of steel bars is more in the concrete component, so need a large amount of core rods to carry out manufacturing of preformed hole; And core rod can only be after the concrete coagulation sclerosis, just can withdraw from, and will have a strong impact on the process of production like this.
Summary of the invention:
The purpose of this invention is to provide a kind of method that has the gauze wire cloth cylinder of preformed hole and carry out the reinforcing bar connection; Make and do not need a large amount of core rods and complicated mold technique, with low cost, simple to operate, the dependable performance of this gauze wire cloth cylinder preformed hole method of removing when precast concrete is manufactured.
Above-mentioned purpose realizes through following technical scheme:
The gauze wire cloth cylinder that has preformed hole; Its composition comprises: the gauze wire cloth cylinder; Described gauze wire cloth cylinder one end opening, end sealing; Its cylinder has helical groove outward, has with barrel near blind end on the described gauze wire cloth cylinder to be communicated with venthole, has with barrel near openend on the described gauze wire cloth cylinder to be communicated with grout hole.
The gauze wire cloth cylinder that has preformed hole carries out the method that reinforcing bar connects; This activities is: the gauze wire cloth cylinder that opening is outside is pre-buried inner in precast concrete, reinforcing bar is inserted openend and shutoff after, be in the milk from grout hole; Venthole nature exhaust air, thus carry out the reinforcing bar anchoring.
Beneficial effect of the present invention:
1. the gauze wire cloth cylinder preformed hole method that the present invention realized; The mold technique of removing that does not need a large amount of core rods and complicacy; Gauze wire cloth cylinder interior rough surface also is suppressed with helical groove; Further reinforcing steel bar anchor connection effect, so switching performance is reliable, characteristics are built in the construction that is suitable for the housing industrialization precast concrete again.
2. simple, the construction quality of this product processing technique is easy to guarantee that work progress does not need complicated mechanical equipment and facility, does not need power consumption yet.The job site is to do operation basically, has fully avoided all disadvantages of traditional preformed hole mode.The building course environmental protection and energy saving, reduce cost, practice thrift construction fund.
3。Accelerate construction speed, improve the construction market more than 30%.
Description of drawings:
Accompanying drawing 1 is this product sketch map.
The specific embodiment:
Embodiment 1:
The gauze wire cloth cylinder that has preformed hole; Its composition comprises: gauze wire cloth cylinder 1; The sealing of described gauze wire cloth cylinder one end opening, an end, its cylinder has helical groove 2 outward, has near blind end on the described gauze wire cloth cylinder to be communicated with venthole 4 with barrel; Have near openend on the described gauze wire cloth cylinder to be communicated with grout hole 3 with barrel, described gauze wire cloth cylinder opening is outwards pre-buried in the inside of precast concrete 5.
Embodiment 2:
The gauze wire cloth cylinder that has preformed hole carries out the method that reinforcing bar connects; This activities is: the gauze wire cloth cylinder that opening is outside is pre-buried inner in precast concrete, reinforcing bar is inserted openend and shutoff after, be in the milk from grout hole; Venthole nature exhaust air, thus carry out the reinforcing bar anchoring.
