Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, in particular to a construction column auxiliary anchor bar planting device and a construction method thereof. BACKGROUND

[0002] The construction column is an important component in the brick-concrete structure building. In order to improve the seismic performance of the multi-storey building masonry structure, the specification requires that the reinforced concrete column should be set at the appropriate position of the building and connected with the ring beam to jointly strengthen the stability of the building. This reinforced concrete column is usually referred to as the construction column. Anchor bar planting, also known as rebar planting, is a connecting technology that uses the locking force of structural glue to tighten the steel bar after anchoring. It is the best choice for structural anchor bar planting reinforcement and heavy load fastening. Anchor bar planting for building structures can strengthen the strength of the building and is commonly used in structural anchor bar planting reinforcement and heavy load fastening.

[0003] In the construction of building engineering, for anchor bar planting at the top of the construction column, the anchor bar is usually planted by first drilling a hole and then planting the anchor bar. In the existing construction column, the anchor bar is usually planted by first planting the bottom steel bar of the construction column on the floor, then binding the steel bar of the construction column, starting to build the masonry, and then planting the top steel bar of the construction column at the bottom of the frame beam when the construction column is built to a certain height. However, at this time, the steel bar of the construction column has already been bound and installed, and the masonry has already been built. When planting the anchor bar, the construction personnel have no working surface to stand on, making it difficult to operate. If the top steel bar of the construction column is planted at the bottom of the beam, due to the high floor, a scaffold working platform needs to be set up or a ladder needs to be used, and the construction personnel need to plant the anchor bar at an upward angle. This not only makes it inconvenient to apply force and reduces the efficiency of anchor bar planting, but also has a high safety risk.

[0004] The existing auxiliary anchor bar planting tool and method with the publication number CN107401281A fixes the fixed bottom plate at the bottom of the part where the anchor bar needs to be planted, then tightens the locking bolt, pushes the connecting rod and the pressure rod upward through the downward action of the pressure rod, the drill bit on the moving column is lifted, the downward pressure of the pressure rod is kept unchanged, the drill bit is turned on, a hole with a depth of 1-2 cm is drilled in the upper cement panel, then the pressure rod is slightly lifted, the drill bit is moved out, the fixed bottom plate is moved 0.5-1 cm in any direction, the pressure rod is lifted, the drill bit is pressed against the drilled hole, the drill bit is turned on and the fixed column is rotated, the drill bit is retracted, the fixed bottom plate returns to the original position, and the drill bit is turned on to drill to the required depth. However, the patent has the following disadvantages:

[0005] 1. The operation of the patent is relatively complex, resulting in a complicated construction process, and the positioning accuracy is not enough to ensure the verticality of the drilling and the accurate alignment of the upper and lower holes, which can easily cause the anchor bar planting hole at the bottom of the beam to deviate too much from the lower construction column steel bar, resulting in phenomena such as exposed steel bar of the construction column and inability to mold.

[0006] 2、The patent can only drill holes, and the subsequent processing of the anchor hole still needs to be performed by the construction personnel, the function is single, and the use effect is poor. SUMMARY

The upward-drilling rotating upper drilling part 8 is located on one side of the base plate 1 and is mounted on the rotating upper drilling part 8. The hole-cleaning part 9, used to clean residue inside the hole, is installed at the bottom of the double lifting part 7 and directly above the circular through hole 3. The laser positioning device 10, a conventional measuring instrument, is used for fixed-point positioning. Before drilling, the position of the base plate 1 is continuously adjusted by screwing to ensure that the laser positioning device 10 is completely aligned with the bottom reinforcing steel of the structural column, thereby completing the overall positional correction of the equipment. This ensures that the concrete drilling machine 87 at the end is on the same straight line as the bottom reinforcing steel of the structural column, thus guaranteeing drilling positioning accuracy.

[0052] The dual lifting section 7 is adapted to perform two linear extensions and retractions to significantly increase the height of the flipping upper drill section 8;

[0053] The overturning and drilling part 8 is suitable for completing the overturning adjustment to expose the relative position of the hole cleaning part 9. The construction column auxiliary rebar planting equipment can align the position of the bottom rebar of the construction column by providing the circular through hole 3 and the laser positioning instrument 10, so that the upper concrete drilling machine 87 is accurately aligned with the bottom rebar of the construction column, thereby ensuring the accurate alignment of the upper and lower holes. At the same time, the mechanical clamping device 86 clamps and fixes the concrete drilling machine 87, avoiding the hole deviation that easily occurs during manual drilling, ensuring the perpendicularity of the drilled hole, and ensuring that the concrete drilling machine 87 drills in a state perpendicular to the rebar planting position of the beam bottom, thereby ensuring the perpendicularity of the hole. The double lifting part 7 can lift the height of the overturning and drilling part 8 twice in succession, thereby ensuring that the height of the overturning and drilling part 8 can be fully lifted to ensure that the hole can be drilled. The overturning and drilling part 8 can stably drill upward in the vertical direction, thereby ensuring the quality of the drilled hole and preventing deviation during drilling. The hole cleaning part 9 can clean and dry the hole after drilling, thereby automatically cleaning the residual in the hole. The construction column auxiliary rebar planting equipment has high drilling positioning accuracy and good drilling quality, can effectively ensure the perpendicularity of the drilling and the accurate alignment of the upper and lower holes, thereby preventing the beam bottom rebar hole from deviating too much from the lower construction column rebar, preventing the appearance of the construction column rebar exposure and the inability to assemble the mold in the later stage, and enabling subsequent processing of the rebar hole. The function is comprehensive, and high-altitude work is avoided, effectively protecting the safety of construction personnel.

[0054] Optionally, the leveling part 6 includes a level 61 embedded in the disc 4 and used to display the level state, a plurality of support bottom blocks 62 circumferentially installed on the base plate 1, a plurality of T-shaped open slots 63 respectively formed in the plurality of support bottom blocks 62, a plurality of the feet 5 respectively supported in the plurality of T-shaped open slots 63, an abutting rod 64 connected to the two sides of the foot 5 and extending into the T-shaped open slot 63, a plurality of cylinders 65 respectively installed on the back of the plurality of counterweights 2 and used to provide a push-pull force, the cylinder 65 is a metal machine part that guides the piston to perform linear reciprocating motion in the cylinder, a pull rod 66 connected to the foot 5 and the output end of the cylinder 65 and used to transmit power, and the state of the level 61 is observed after the laser positioning instrument 10 is aligned with the bottom rebar of the construction column. Then, the corresponding cylinder 65 is driven to pull backward or push forward the corresponding foot 5, thereby ensuring that the level 61 can be adjusted to the level state to ensure the level of the disc 4, and thereby ensuring that the double lifting part 7 and the overturning and drilling part 8 do not appear skewed, and ensuring the perpendicularity of the hole drilled by the overturning and drilling part 8.

[0055] The pull rod 66 is in the shape of a "T", which increases the force receiving surface of the foot 5, thereby ensuring that the foot 5 is more stably driven by the cylinder 65.

[0056] Optionally, the double lifting part 7 comprises a receiving cylinder 71 installed on the disc 4, an external thread column 72 spirally installed in the receiving cylinder 71, an intermediate circular table 73 installed on the top of the external thread column 72 and used for rotating the external thread column 72 up and down, a plurality of rotating handle bars 74 circumferentially installed on the side of the intermediate circular table 73 and used for reducing the rotating difficulty, an external sleeve 75 installed on the intermediate circular table 73, a sliding support column 76 slidingly inserted in the external sleeve 75 and used for external sliding and internal shrinking, a plurality of bolts 77 equidistantly and spirally installed on the external sleeve 75 and the sliding support column 76 and used for fixing the sliding support column 76, and threaded holes 78 collinearly and opened on the external sleeve 75 and the sliding support column 76 and matchable with the bolts 77. After the leveling of the disc 4 is completed, the bolts 77 are firstly taken out, the sliding support column 76 is pulled out upward, then the bolts 77 are screwed into the corresponding threaded holes 78 respectively to fix the sliding support column 76 again, so as to prevent it from sliding into the external sleeve 75 during drilling, then the rotating handle bars 74 are held and continuously rotated to rotate the intermediate circular table 73, and the external thread column 72 is continuously screwed out, so that the concrete drilling machine 87 is sent to the position 1-3 cm below the beam bottom by twice lifting, to ensure the smooth drilling and avoid the manual drilling by the construction personnel at a high place. The lifting is firstly performed by the external sleeve 75 and the sliding support column 76, and then by the rotating of the external thread column 72 by holding and rotating the rotating handle bars 74, so that the construction personnel can more easily exert force, the labor intensity of the construction personnel is reduced, and the lifting difficulty is reduced.

[0057] Optionally, the turning and drilling part 8 comprises a screw jack 81 installed on the top of the sliding support column 76 and used for lifting the external object, an end connector 82 installed on the output end of the screw jack 81, a mandrel 83 installed in the end connector 82 and used for providing a rotating base, a turning block 84 rotatably installed on the mandrel 83, long bolts 85 tightly inserted on the end connector 82 and penetrating through both ends of the turning block 84 and used for fixing the turning block 84, clamping devices 86 installed on the front of the turning block 84, and a concrete drill 87 arranged on the clamping devices 86 and used for drilling. When lifted to the position, the concrete drill 87 and the screw jack 81 are simultaneously driven to ensure that the screw jack 81 pushes the concrete drill 87 upward to perform the drilling operation. The clamping devices 86 are selected from existing common clamps, which can firmly clamp the concrete drill 87. The mechanical clamps used for fixing the concrete drill 87 can well ensure the verticality of the concrete drill 87, avoid the inclination of the manually held concrete drill 87, and thus ensure the verticality of the drilled hole. The screw jack 81 is an existing basic lifting component. The use of the screw jack 81 to push the concrete drill 87 upward to perform the drilling can ensure the linear upward movement of the concrete drill 87, further prevent the hole from being drilled obliquely, and well control the drilling depth.

[0058] Optionally, the hole cleaning part 9 comprises a water storage tank 91 used for storing cleaning water, a high-pressure water pump 92 installed on the water storage tank 91 and extending into the water storage tank 91 through an external pipeline and used for pressurized water supply. The high-pressure water pump 92 is an existing water treatment tool, which can increase the water pressure. A water jet pipe 93 is installed on the back of the turning block 84 and used for water jetting. A water delivery pipe 94 is connected to the water jet pipe 93 and the water outlet of the high-pressure water pump 92 at both ends. A wind drying device 95 is arranged on one side of the water storage tank 91 and used for accelerating the surface drying. After the drilling is completed, the turning and drilling part 8 is lowered to the original height, the two long bolts 85 are removed, and then the turning block 84 is turned by 180 degrees and inserted into the two long bolts 85 again to realize the position inversion of the concrete drill 87 and the water jet pipe 93. Then, the turning and drilling part 8 is lifted to the position 1-3 cm below the beam bottom. It is ensured that the water jet pipe 93 can face the just drilled hole. At this time, the high-pressure water pump 92 is driven to pump the water in the water storage tank 91 and deliver it through the water delivery pipe 94 and then jet it out from the water jet pipe 93 toward the hole, so as to realize the high-pressure flushing of the inside of the hole. Then, the residual dust, cement slag, etc. in the hole are flushed out, the hole is cleaned and neat, and thus the bonding strength after the hole is filled with the anchorage adhesive cannot be realized as designed to affect the actual effect of the anchorage.

[0059] Optionally, the wind drying device 95 comprises an air pump 951 for blowing, which is a tool capable of generating air pressure, an air outlet pipe 952 installed on the back of the turnover block 84, and an air conveying pipe 953 connected to the air outlet pipe 952 and the air outlet of the air pump 951 respectively and used for conveying air. After cleaning is completed, the air pump 951 is started to generate air flow, which is conveyed through the air conveying pipe 953 and blown out by the air outlet pipe 952 towards the hole just drilled, so as to continuously blow air into the hole, accelerate evaporation of moisture in the hole, and further effectively accelerate the drying speed inside the hole, so that the construction personnel can perform glue pouring and bar dowel faster and improve construction efficiency.

[0060] The water spraying pipe 93 and the air outlet pipe 952 are convergent, ensuring that the water spraying pipe 93 and the air outlet pipe 952 can act on the hole.

[0061] Optionally, the leveling part 6 further comprises a hydraulic rod 67 installed between the counterweight 2 and the foot 5 and used for strengthening stability. The hydraulic rod 67 is a device for completing mechanical movement by using hydraulic principle, which has the advantages of being able to bear a large amount of weight and being able to support the weight at different angles and directions. When the foot 5 is adjusted by the air cylinder 65, the corresponding hydraulic rod 67 is synchronously driven, ensuring that the hydraulic rod 67 can support the foot 5 after the air cylinder 65 stops, preventing the foot 5 from moving backward due to the pressure transmitted during drilling and causing the self-locking function of the air cylinder 65 to be forcibly destroyed. The construction stability of the device is improved, collapse is prevented, and the air cylinder 65 is protected from being damaged.

[0062] Optionally, the wind drying device 95 further comprises a one-way valve 954 installed at the tail of the air outlet pipe 952 and used for preventing foreign matters from entering. While ensuring that air flow can be blown out, the one-way valve 954 prevents dust and cement blocks mixed with water from blocking the air outlet pipe 952 during flushing of the hole, preventing failure of the function of the wind drying device 95.

[0063] The turnover upper drilling part 8 further comprises an umbrella-shaped protective plate 88 installed on the end connector 82 and used for shielding water and dust. The umbrella-shaped protective plate 88 is made of glass or transparent plastic material, preventing dust and water during drilling and flushing from falling on the drive devices such as the screw rod elevator 81 and the air cylinder 65 and causing failure, while not hindering the construction personnel from observing the drilling process in real time.

[0064] The outer threaded column 72 is screwed with a spiral sleeve 79, which increases the limited length of the outer threaded column 72 and prevents it from shaking during drilling.

[0065] Optionally, it is particularly pointed out that the umbrella-shaped protective plate 88 is provided with a plurality of sewage collection grooves surrounding a circle, the water storage tank 91 is provided with a backflow port, and the backflow port on the water storage tank 91 is connected with the sewage collection grooves through a pipeline, and a filtering device is installed at the backflow port on the water storage tank 91, so that the water after cleaning the holes is filtered by the sewage collection grooves, the pipeline and the filtering device in turn and then backflows into the water storage tank 91 for reuse next time, realizing the reuse of water resources and saving water.

[0066] Optionally, a handle 21 is installed on the counterweight 2 to facilitate the construction personnel to lift and move the device;

[0067] The water storage tank 91 and the air pump 951 are arranged on the trolley 11, which ensures quick and flexible transfer and improves convenience.
