Description

Technical Field

[0001] This invention relates to the field of civil engineering construction technology, specifically to a rebar installation kit and construction method for secondary structures in civil engineering construction. Background Technology

[0002] In secondary structures of civil engineering construction, rebar anchoring technology involves embedding steel bars into concrete walls, slabs, and columns to achieve an effective connection between the old and new concrete structures, enhancing the overall integrity and stability of the structure. However, during the rebar anchoring process, it is often difficult to thoroughly clean the holes drilled with an electric drill. Dust, debris, and other impurities remaining in the holes can affect the bonding effect between the anchoring adhesive and the steel bars and concrete, failing to guarantee the strength in pull-out tests. Simultaneously, the injection of the anchoring adhesive is not always uniform, easily resulting in air bubbles and voids, leading to insufficient anchoring force of the rebar. Furthermore, rebar anchoring has low construction efficiency, making it difficult to meet the needs of large-scale civil engineering construction. Summary of the Invention

[0003] The technical problem to be solved by this invention is that the dust accumulated in the drilling holes during existing secondary rebar installation is difficult to clean, and the anchoring force of the rebar is insufficient.

[0004] The technical solution adopted by the present invention to solve the aforementioned problem is as follows: A secondary structure rebar installation kit for civil engineering construction includes: Drilling apparatus, including an electric drill and a drill bit, for drilling rebar holes at predetermined locations in a wall; The hole cleaning device is installed at the opening of the rebar hole to clean the sand and dust in the rebar hole; The adhesive injection device is used to inject adhesive into the anchor holes.

[0005] Compared with the prior art, the present invention employing the above structure has the following advantages: The present invention has three main features: first, it uses a drilling and cleaning component to drill holes in concrete walls and slabs to clean and collect dust; second, it uses a rebar injection component to inject adhesive into the holes for full and even injection; and third, it uses a rebar positioning component to assist in accurate positioning.

[0006] As a preferred option, a further technical solution to the above structure is: As an alternative, the dispensing device includes: The adhesive storage tank is a sealed container that stores rebar adhesive inside. The glue injection head is connected to the outlet of the glue storage tank via a glue injection hose; A stirring rod is installed inside the glue storage tank. Its lower end is rotatably connected to the bottom of the glue storage tank, and its upper end passes through the top wall of the glue storage tank and is equipped with a drive motor. A pressure pump, installed on the glue storage tank, is used to control the air pressure inside the storage tank.

[0007] Furthermore, it also includes a rebar positioning device, which comprises: The positioning frame is a hollow rectangular outer frame. The top plate has a groove along its length on the upper surface, and the bottom plate has bolt holes evenly distributed along its length. The positioning cylinders are evenly arranged inside the positioning frame. Their upper side is connected to the top plate of the positioning frame through a sliding block, and their lower side is connected to the bottom plate of the positioning frame through a support block. The upper connecting component includes a U-shaped connecting plate. The lower end of the U-shaped connecting plate is fixed to the positioning cylinder, and the upper end is set on the upper side of the top plate of the positioning frame. A through pin is provided through the upper end, and a slider is fixed to the lower end of the through pin. The slider is installed in the slide groove. A spring is fitted on the through pin. The upper end of the spring abuts against the U-shaped connecting plate, and the lower end abuts against the slider. The lower connecting component includes an L-shaped support plate, the upper end of which is fixed to the positioning cylinder, and the horizontal part is connected to the bottom plate of the positioning frame by fixing bolts.

[0008] The support frame includes two telescopic columns, with a base plate fixed to the lower end of each column and the upper ends of the columns fixed to both sides of the positioning frame.

[0009] Alternatively, the brush head includes a metal shaft and a disc-shaped fiber brush. One end of the metal shaft is equipped with a structure that mates with an electric drill, and the other end is fixed with a cross key. The brush head has a base at its center, and the base has a groove in the middle that matches the cross key.

[0010] As an alternative, the conical sealing sleeve is made of flexible rubber material. When the dust-absorbing sleeve is pressed against the wall, its cone bends and its surface deforms, thus making close contact with the rough surface of the wall.

[0011] Alternatively, a rubber layer is adhered to the surface of the protective cone that contacts the electric drill, and the rubber layer is in close contact with the surface of the electric drill.

[0012] Alternatively, one end of the dispensing head is sealed to the dispensing hose, while the other end is closed, and the side wall of the dispensing head is provided with a dispensing hole.

[0013] As an option, wheels are installed under the seat.

[0014] To address the aforementioned problems, the present invention also provides a construction method, the specific solution of which is as follows.

[0015] Based on the above construction method for the secondary structure rebar installation kit in civil engineering construction, the following steps shall be followed: S1: Rebar hole positioning: Align the positioning cylinders of the positioning frame with the positions where rebar needs to be installed, and mark them on the wall surface. S2: Drilling: Install the drill bit onto the electric drill; after assembling the hole cleaning device, fasten the dust suction sleeve to the rebar installation position, insert the drill bit into the dust suction sleeve to perform drilling operations, and stop when the drilled rebar installation hole reaches the predetermined depth.

[0016] S3: Cleaning the drill hole: a. During the drilling operation, start the vacuum cleaner and suck the debris and dust generated during the drilling process into the vacuum cleaner through the vacuum hole; b. After the drilling is completed, replace the brush head with the electric drill and use the electric drill to repeatedly push and pull the brush head to clean the rebar hole. The vacuum cleaner continues to work until the brush head has cleaned the rebar hole, and then remove the hole cleaning device. S4: Injecting anchoring adhesive: Insert the injection head deep into the anchoring hole, start the stirring rod to stir the anchoring adhesive in the storage tank, then turn on the pressure pump to deliver the well-stirred anchoring adhesive to the injection head through the injection hose. The anchoring adhesive is injected into the anchoring hole from the injection head. After the anchoring hole is full of adhesive, remove the injection device. S5: Inserting Rebar: Place the rebar into each positioning cylinder of the positioning frame. Adjust the height of the support frame to ensure that the rebar is accurately aligned with the anchoring hole. Then, slowly insert the rebar into the anchoring hole filled with anchoring adhesive until the rebar reaches the predetermined depth to complete the anchoring operation. Attached Figure Description

[0019] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0020] See Figures 1 to 7 This invention provides a secondary structure rebar installation kit for civil engineering construction, comprising: Drilling apparatus, including an electric drill and a drill bit, for drilling rebar holes at predetermined locations in a wall; The hole cleaning device is installed at the opening of the rebar hole to clean the sand and dust in the rebar hole; The adhesive injection device is used to inject adhesive into the anchor holes.

[0021] The hole cleaning device includes: Brush head, installed at the end of the electric drill; The dust-collecting sleeve has a conical sealing sleeve installed at one end, which abuts against the wall surface and covers the outside of the rebar hole; the other end is provided with a protective cone for accommodating the end of the electric drill, and the tip of the protective cone is provided with a through hole for the brush head and drill bit to pass through; and a dust-collecting hole is provided at the bottom. The vacuum cleaner is connected to the suction port via a delivery tube.

[0022] Optionally, the conical sealing sleeve is made of flexible rubber material. When the dust-absorbing sleeve is pressed against the wall, its cone bends and deforms, and its surface deforms, thus making close contact with the rough surface of the wall.

[0023] Optionally, a rubber layer is adhered to the surface of the protective cone that contacts the electric drill, and the rubber layer is in close contact with the surface of the electric drill.

[0024] The brush head includes a metal shaft and a disc-shaped fiber brush. The rear end of the metal shaft has a structure similar to that of a drill bit, which is used in conjunction with an electric drill, and the front end is fixed with a cross key. The center of the brush head has a base with a groove in the middle that matches the cross key. The fibers of the fiber brush are inclined, specifically from the base backward. The brush head is used to clean debris from the anchoring hole. When the brush head moves deeper into the anchoring hole, the fibers move in the direction of travel. When encountering small debris particles, the fibers retract inward, exerting little force on the small particles. However, when the brush head moves outward from the anchoring hole, the fibers expand outward due to the influence of the hole wall, pushing the small debris particles outward when they encounter them.

[0025] The dispensing device includes: The adhesive storage tank is a sealed container that stores rebar adhesive inside. The glue injection head is connected to the outlet of the glue storage tank via a glue injection hose; A stirring rod is installed inside the glue storage tank. Its lower end is rotatably connected to the bottom of the glue storage tank, and its upper end passes through the top wall of the glue storage tank and is equipped with a drive motor. A pressure pump, installed on the glue storage tank, is used to control the air pressure inside the storage tank.

[0026] Optionally, one end of the dispensing head is sealed to the dispensing hose, and the other end is a closed end, with a dispensing hole provided on the side wall of the dispensing head.

[0027] Further, see Figures 8 to 10 The secondary structure rebar installation kit for civil engineering construction of this invention also includes a rebar positioning device, the specific structure of which is as follows: The positioning frame is a hollow rectangular outer frame. The top plate has a groove along its length on the upper surface, and the bottom plate has bolt holes evenly distributed along its length. The positioning cylinders are evenly arranged inside the positioning frame. Their upper side is connected to the top plate of the positioning frame through a sliding block, and their lower side is connected to the bottom plate of the positioning frame through a support block. The upper connecting component includes a U-shaped connecting plate. The lower end of the U-shaped connecting plate is fixed to the positioning cylinder, and the upper end is set on the upper side of the top plate of the positioning frame. A through pin is provided through the upper end, and a slider is fixed to the lower end of the through pin. The slider is installed in the slide groove. A spring is fitted on the through pin. The upper end of the spring abuts against the U-shaped connecting plate, and the lower end abuts against the slider. The lower connecting component includes an L-shaped support plate, the upper end of which is fixed to the positioning cylinder, and the horizontal part is connected to the bottom plate of the positioning frame by fixing bolts.

[0028] The support frame includes two telescopic columns, with a base plate fixed to the lower end of each column and the upper ends of the columns fixed to both sides of the positioning frame.

[0029] The fixing bolts are screwed into the bolt holes through the horizontal part of the L-shaped support plate. The density of bolt holes on the bottom plate of the positioning frame is greater than that of the positioning cylinder. According to the construction design, the lower connecting component can be fixed on different bolt holes. When the lower connecting component is moved, the upper connecting component slides together. The upper connecting component is designed as a sliding connection to facilitate the movement of the positioning cylinder.

[0030] Optionally, wheels are installed under the seat.

[0031] The construction method for the above-mentioned secondary structure rebar installation kit in civil engineering construction shall be carried out according to the following steps: S1: Rebar Hole Positioning: Align the positioning cylinders of the positioning frame with the locations where rebars need to be installed, and mark them on the wall surface. Specifically, cross marks can be used.

[0032] S2: Drilling: The drill bit is installed on the electric drill; after assembling the hole cleaning device, the dust-collecting sleeve is fastened to the rebar anchoring position, and the drill bit is inserted into the dust-collecting sleeve to perform drilling operations. The drilling stops when the rebar anchoring hole reaches the predetermined depth. Specifically, the outer edge of the tapered sealing sleeve of the dust-collecting sleeve is marked at both ends in the vertical and horizontal directions in advance to facilitate alignment with the cross marks.

[0033] S3: Cleaning the drill hole: a. During the drilling operation, start the vacuum cleaner and suck the debris and dust generated during the drilling process into the vacuum cleaner through the suction hole; b. After the drilling is completed, replace the brush head with the electric drill and use the electric drill to repeatedly push and pull the brush head to clean the rebar hole. The vacuum cleaner continues to work until the brush head has cleaned the rebar hole, and then remove the hole cleaning device.

[0034] S4: Injecting anchoring adhesive: Insert the injection head deep into the anchoring hole, start the stirring rod to stir the anchoring adhesive in the storage tank, then turn on the pressure pump to deliver the well-stirred anchoring adhesive to the injection head through the injection hose. The anchoring adhesive is injected into the anchoring hole from the injection head. After the anchoring hole is full of adhesive, remove the injection device.

[0035] S5: Inserting Rebar: Place the rebar into each positioning cylinder of the positioning frame. Adjust the height of the support frame to ensure that the rebar is accurately aligned with the anchoring hole. Then, slowly insert the rebar into the anchoring hole filled with anchoring adhesive until the rebar reaches the predetermined depth to complete the anchoring operation.

[0036] The present invention has three main features: first, it uses a drilling and cleaning component to drill holes in concrete walls and slabs to clean and collect dust; second, it uses a rebar injection component to inject adhesive into the holes for full and even injection; and third, it uses a rebar positioning component to assist in accurate positioning.
