When the anchor 204 pierces the flexible plugging member 11 through the sleeve 20, the hole after the flexible plugging member 11 is pierced has a certain extrusion force to the sleeve 20 because the surface of the sleeve 20 is smooth, so that the adhesive 205 attached to the sleeve 20 can be blocked in the through hole 201 as much as possible, and the rear surface of the sleeve 20 passing through the plugging member 11 is clean. Therefore, the bar planting device not only ensures the anchoring quality of the bar planting of the concrete member, but also has the advantages of saving bar planting glue and facilitating later construction.

Wherein the anchor 204 may be a ribbed bar or a full-threaded screw.

Specifically, the operation method for planting the bars on the through holes of the concrete member by using the bar planting device comprises the following steps:

referring to fig. 3 to 9, when the concrete is drilled into the through hole 201 to anchor the bar, firstly, the blocking component 10 is installed on the bar-planting side 202 of the through hole 201 on the concrete member 200, then, the glue injection construction is performed in the through hole 201 according to the requirement, after the glue injection is completed, the sleeve 20 is sleeved at the front end of the anchoring piece 204 and then is implanted into the through hole 201 together with the anchoring piece 204, when the front end of the reinforcing steel bar provided with the sleeve 20 is penetrated out from the bar-planting side 202 of the through hole 201, the blocking component 11 installed outside the through hole 201 blocks the adhesive 205 attached to the sleeve 20, and after the length of the anchoring piece 204 penetrated out of the through hole 201 reaches the requirement, the sleeve 20 on the blocking component 10 and the anchoring piece 204 is removed, thus the bar-planting construction of the anchoring piece 204 is completed.

In some embodiments, closed end 22 is a tapered end. By setting the closed end 22 of the sleeve 20 to be a tapered end, the tapered end can make the sleeve 20 puncture the plugging member 11 more easily, and the tapered end can make the hole on the plugging member 11 gradually become larger in the process of puncturing the plugging member 11 by the sleeve 20, and the size of the hole is a continuous gradual change process, so that the adhesive 205 attached to the sleeve 20 can be blocked in the through hole 201 as much as possible.

The plugging member 11 may be made of various materials, for example, the plugging member 11 may be made of a flexible rubber plastic product, and has a plate-shaped structure.

In some embodiments, the closure 11 is a flexible rubber and plastic article. Through adopting shutoff piece 11 as flexible rubber and plastic goods, the convenience of drawing materials to flexible rubber and plastic goods has stronger toughness and certain deformability, and the toper end of sleeve pipe 20 can puncture shutoff piece 11 relatively easily, and the shutoff piece 11 after puncturing is formed with the hole, and the inner wall in hole can wrap up the sleeve pipe 20 outer wall tightly and form effective parcel, and sleeve pipe 20 is under the extrusion of shutoff piece 11 hole inner wall all around to with the adhesive 205 that sleeve pipe 20 self adheres to in through-hole 201, the adhesive 205 in the through-hole 201 not only can not be carried out by the reinforcing bar adhesion like this, and can also effectively strike off the adhesive 205 that adheres to on the sleeve pipe 20, has reduced the clearance degree of difficulty of follow-up sleeve pipe 20.

In some embodiments, the blocking assembly 10 further includes a pressing plate 12, the pressing plate 12 is provided with a relief hole 120 for passing through the front end of the anchor 204, the blocking member 11 is disposed on one side of the pressing plate 12 near the concrete member 200, and the pressing plate 12 is used for attaching the blocking member 11 to the bar planting side 202 of the concrete member 200. Because the plugging piece 11 is a flexible rubber-plastic product and has certain elasticity, when the anchoring piece 204 punctures the plugging piece 11, the whole plugging piece 11 possibly generates a gap between the puncture force of the anchoring piece 204 and the anchoring side 203 of the concrete member 200, and then the risk of the adhesive 205 flowing out can be possibly caused, therefore, the pressing plate 12 is arranged on one side of the plugging piece 11, which is away from the through hole 201, and the pressing plate 12 is a rigid part, and the pressing plate 12 can tightly press the plugging piece 11 on the bar planting side 202 of the concrete member 200, so that the phenomenon of glue leakage caused by the displacement of the plugging piece 11 when the anchoring piece 204 is used for bar planting is avoided.

The material of the pressing plate 12 may be a steel plate, a template, a plastic plate, or the like. In the present embodiment, the pressing plate 12 is a steel plate. In addition, when the anchor 204 is used for reinforcing the bar, the pressing plate 12 may be used to press the block 11 against the reinforcing side 202 of the concrete member 200 by a worker manually applying pressure, or may be used to press the block 11 against the reinforcing side 202 of the concrete member 200 by the external pressing member 13 acting on the pressing plate 12.

In actual engineering, as shown in fig. 1, when the anchoring piece 204 is used for planting the steel bar, two workers can cooperate, one worker penetrates the anchoring piece 204 into the through hole 201 at the anchoring side 203 of the concrete member 200, and the other worker applies construction pressure to the pressing plate 12 at the steel bar planting side 202 of the concrete member 200, so that the plugging piece 11 is abutted against the steel bar planting side 202 of the concrete member 200, and the steel bar planting construction of the anchoring piece 204 is facilitated.

In some embodiments, the forward projection of the closure element 11 on the bar planting side 202 of the concrete member 200 is located within the forward projection of the platen 12 on the bar planting side 202 of the concrete member 200. Controlling the coverage area of the platen 12 to completely cover the plugging member 11 reduces the degree of deformation of the plugging member 11.

In some embodiments, the aperture of relief hole 120 is larger than the aperture of through hole 201. The hole diameter of the avoidance hole 120 is larger, and enough allowance is provided for the anchor 204 to pass through, so that the difficulty of bar planting of the anchor 204 is reduced.

In some embodiments, the blocking assembly 10 further comprises a pressing member 13, the pressing member 13 being adapted to act on the pressing plate 12 to press the closure element 11 against the bead-planting side 202 of the concrete element 200. By providing the pressing member 13 on the back side of the pressing plate 12, the pressing member 13 provides a pressing force, so that the blocking member 11 can be tightly pressed against the bar planting side 202 of the concrete member 200, manual participation of workers is not required, and the construction is more convenient.

The pressurizing member 13 may be various, for example, the pressurizing member 13 may be a fixing bolt, a cylinder, a jack, a supporting skid, or the like.

Alternatively, referring to fig. 2, when the pressing part 13 is a fixing bolt, a connection hole is provided at a corner of the pressing plate 12, and the connection hole is used for the fixing bolt to pass through to fix the pressing plate 12 to the bar planting side 202 of the concrete member 200, so that the pressing plate 12 can press the blocking piece 11 against the bar planting side 202 of the concrete member 200.

Alternatively, when the pressurizing member 13 is a cylinder or a jack (not shown in the drawings), the driving end of the cylinder or the jack acts on the side of the pressing plate 12 facing away from the through hole 201, and provides a pressing force to the pressing plate 12 to press the blocking piece 11 against the bead planting side 202 of the concrete member 200.

Alternatively, when the pressing member 13 is employed as a support skid (not shown in the drawings), i.e., is diagonally supported; one end of the support skid is vertically or obliquely abutted against the wall foot or other holding surface of the concrete member 200, and the other end is abutted against the pressing plate 12, so that the pressing plate 12 is provided with an abutting force to press the plugging piece 11 against the bar planting side 202 of the concrete member 200.

The length of the sleeve 20 may be set according to the actual engineering situation.

In some embodiments, the inner diameter of the cannula 20 matches the outer diameter of the anchor 204. Specifically, the anchor 204 is typically a rebar or sleeve 20 with an inner diameter determined by the rebar or bolt specification of the rebar to be planted.
