Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a pre-buried reinforcement construction method. Background Art

[0002] In recent years, post-embedded reinforcement is often used in the construction of tie bars between infill walls and load-bearing walls, columns, beams, and slabs. Although this construction method is convenient, it often leads to poor anchoring of the steel bars due to quality problems of the anchoring glue or grouting materials, and improper drilling, hole cleaning, glue injection, or grouting operations, which fail to play the proper tie-binding role. Normally, after the main structure is completed, the workers need to locate and drill holes on the end faces of the shear walls and the bottom faces of the beams and slabs according to the positions on the drawings. It often happens that the steel bars of the beams or walls are hit during drilling, resulting in the hole being invalidated. The workers will continue to drill holes next to them until they can reach the depth required by the specifications, which is generally 100mm-120mm. Secondary drilling is required to avoid the steel bars, and the resulting deviation accounts for about 30% of the total number of holes drilled. Secondly, because drilling requires manual operation with an electric hammer, more than 40% of the rebar holes are not vertical, resulting in crooked holes after rebar is planted. After drilling, the holes need to be cleaned with a hair dryer and a brush. The dust left by drilling will seriously affect the pull-out strength after rebar is planted. Finally, when planting the rebar, the rebar glue must be strictly mixed according to the ratio, and the rebar should be fully coated with glue and then stuffed in. It is advisable to wait for it to solidify if it overflows. At this point, the rebar planting work is completed. During this process, a series of problems will be involved, such as damage to the main structure steel bars, the appearance of concrete, the deviation of the structural column steel bars causing difficulty in closing the mold, the rebar pulling strength not meeting the requirements, drilling dust pollution, noise pollution, occupational diseases, etc. Summary of the Invention

[0003] The present invention aims to solve the above problems, thereby providing a pre-buried rebar planting construction method that can firmly anchor the steel bars.

[0004] The present invention solves the above problems by adopting the following technical solutions:

[0005] A pre-buried reinforcement construction method comprises the following steps:

[0006] S1: A prepared embedded part in a tubular shape with one end blocked, wherein the open end of the embedded part is provided with a base, and the inner wall of the open end of the embedded part is provided with an internal thread.

[0007] S2: A bag of anchoring glue is placed in the embedded part, and a glue blocking structure is provided on the inner side of the embedded part and adjacent to the inner end of the internal thread, and a stirring hole is opened at the center of the glue blocking structure.

[0008] S3: After the main formwork is installed, drill holes at the designed locations of the rebar holes.

[0009] S4: On the inner side of the template, fit the base of the embedded part onto the template with the open end facing the rebar hole. On the outer side of the template, use a positioning piece to penetrate the rebar hole and screw it to the embedded part. The positioning piece fixes the embedded part to the template.

[0010] S5: Pour the concrete. After the concrete is formed, remove the positioning parts. During the secondary structure construction, a stirring rod is passed through the anchor bolt hole and the mixing hole and extends into the embedded parts. The end of the stirring rod is connected to an electric pistol drill for stirring. During the stirring process, the bagged anchor bolt glue is destroyed. After the glue is stirred evenly, remove the stirring rod.

[0011] S6: Push the prepared steel bars into the embedded parts through the anchor holes to ensure that the steel bars are fully wrapped with glue to complete the anchoring.

[0031] The present invention will be further described below with reference to the embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0032] A pre-buried reinforcement construction method comprises the following steps:

[0033] S1: A prepared embedded component in a tubular shape with one end blocked is provided. The open end of the embedded component is provided with a base 4, and the inner wall of the open end of the embedded component is provided with an internal thread.

[0034] S2: A bag of anchoring glue is placed in the embedded part, and a glue blocking structure is provided on the inner side of the embedded part and adjacent to the inner end of the internal thread, and a stirring hole is opened at the center of the glue blocking structure.

[0035] S3: After the main formwork is installed, drill holes at the designed locations of the rebar holes.

[0036] S4: On the inner side of the template, the base 4 of the embedded part is attached to the template with the open end facing the anchor hole. On the outer side of the template, a positioning part 5 is used to pass through the anchor hole and screw it to the embedded part. The positioning part 5 fixes the embedded part to the template.

[0037] S5: Pour concrete. After the concrete is formed, remove the positioning part 5. During the secondary structure construction, a stirring rod is passed through the anchor hole and the mixing hole and extends into the embedded part. The end of the stirring rod is connected to an electric pistol drill for stirring. The bagged anchor glue is destroyed during the stirring process. After the glue is stirred evenly, the stirring rod is taken out. The hand drill enters the embedded part through the stirring hole to stir and damage the outer skin of the bagged anchor glue. The glue blocking component ensures that the bagged anchor glue does not leak out for a short time after being pierced.

[0038] S6: Push the prepared steel bars into the embedded parts through the anchor holes to ensure that the steel bars are fully wrapped with glue to complete the anchoring.

[0039] Furthermore, the embedded parts include a left shell 1 and a right shell 2 relative to each other, and the left shell 1 and the right shell 2 are made of nylon. The contact surfaces of the left shell 1 and the right shell 2 are provided with positioning grooves and positioning strips for mutual use. A positioning groove is provided on the left shell 1, and a positioning strip is provided on the right shell 2. Card slots are provided at intervals on both sides of the shell of the right shell 2, and buckles 3 for mutual use with the card slots are provided on both sides of the shell of the left shell 1.

[0040] Furthermore, the two sides of the bagged anchor glue are clamped between the contact surfaces of the left shell 1 and the right shell 2, and the position of the bagged anchor glue is fixed to facilitate puncturing, which can also prevent leakage between the left shell 1 and the right shell 2 when pouring concrete.

[0041] Furthermore, the rubber blocking structure includes a semi-annular elastic thin partition 6 respectively arranged on the inner side of the left shell 1 and the right shell 2 and close to the internal thread. The elastic thin partition 6 is made of nylon. After the left shell 1 and the right shell 2 are docked, the two semi-annular elastic thin partitions 6 form a ring with a stirring hole in the middle of the ring. The semi-annular elastic thin partition 6 is composed of a number of fan-shaped partition units. The elastic thin partition 6 ensures that the embedded rebar bag does not leak out in a short time after being punctured. The diameter of the steel bar is larger than the diameter of the stirring hole. The subsequent steel bars are directly pressed against the annular elastic thin partition 6 and inserted into the embedded parts.

[0042] Furthermore, multiple layers of outer anti-slip ribs 7 are provided along the circumferential direction of the outer periphery of the embedded part to enhance the bonding performance with the concrete.

[0043] Furthermore, reinforcing ribs 8 are provided on the outside of the embedded part and between adjacent outer anti-slip ribs 7 to prevent the embedded part from being deformed.

[0044] Furthermore, multiple layers of inner anti-slip ribs 9 are circumferentially arranged along the inner circumference of the embedded part. The inner anti-slip ribs 9 and the outer anti-slip ribs 7 are located at the same horizontal position to increase the gripping force. The inner diameter of the inner anti-slip ribs 9 is adapted to the steel bars to increase the stability of the steel bars in the embedded part.

[0045] Furthermore, a plurality of anti-tilt ribs 10 are provided outside the open end of the embedded part. One side of the anti-tilt rib 10 is in contact with the inner side surface of the template. The anti-tilt rib 10 further ensures that the embedded part is perpendicular to the template.

[0046] Furthermore, the positioning member 5 includes a screw that is threadedly connected to the open end of the embedded part. The outer end of the screw is provided with a clamping platform that is clamped on the outside of the template. An operating rod is provided on the surface of the clamping platform away from the screw. The operating rod controls the rotation of the screw, and the clamping platform is pressed against the outside of the template for limiting the position.

[0047] First, determine the drilling position, and then fix the embedded parts on the template through the positioning parts 5 for pre-embedding to prevent displacement, and fit the base 4 on the inner side of the template to ensure the verticality of the rebar hole. After the concrete is formed, use a hand drill to pass through the mixing hole to stir and destroy the bagged rebar glue, insert the steel bars into the embedded parts, ensure that the steel bars are fully wrapped by the glue, complete the rebar planting, and avoid damage to the concrete. Secondly, it solves a series of problems such as dust pollution, noise pollution, and occupational diseases caused by traditional drilling.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the scope of the present invention. Any equivalent changes made using the contents of the present invention specification and its drawings are included in the scope of the present invention.
