Description

Technical Field

[0001] The present application relates to the field of construction tools, and in particular to a template structure for concrete construction with reduced honeycomb surface. Background Art

[0002] Concrete formwork is a mold used to cast concrete. Traditional concrete formwork is made of wooden formwork or steel formwork.

[0003] The applicant has found that for some concrete castings with an inverted T-shaped structure, honeycombing is likely to occur on the surface of the concrete castings after molding, which affects the molding quality and load-bearing effect of the concrete castings to a certain extent.

[0004] The applicant analyzed that this might be because, when casting the concrete castings of the inverted T-shaped structure, due to the limitations of factors such as the length and flexibility of the steel bars tied in the inverted T-shaped concrete formwork and the concrete vibrator, it was difficult for the vibrator to vibrate the concrete in the base part of the inverted T-shaped structure at the bottom of the concrete formwork. It was difficult to vibrate the concrete in the concrete formwork in all directions without omission, and it was difficult to quickly expel the bubbles in the concrete, resulting in honeycombed surfaces on the surface of the formed concrete castings, which to a certain extent affected the forming quality and bearing effect of the concrete castings, that is, reduced the quality of the concrete castings. Summary of the Invention

[0005] In order to improve the problem that the foundation part of the inverted T-shaped structure at the bottom of the concrete formwork is difficult to vibrate, resulting in honeycombing and roughness on the surface of the concrete casting after molding, thereby reducing the molding quality of the concrete casting, the present application provides a formwork structure for concrete construction that reduces honeycombing and roughness.

[0006] This application provides a concrete construction formwork structure with reduced honeycomb surface, which adopts the following technical solutions:

[0007] A formwork structure for concrete construction with reduced honeycombed surface, comprising a bottom plate, side plates and end plates, wherein the side plates and the end plates are respectively fixedly connected to the bottom plate, and a pouring space is formed by surrounding the bottom plate, and a plurality of circular tubes are fixedly connected to the side of the side plate facing away from the pouring space, wherein the circular tubes penetrate the side plate and are connected to the pouring space, and the circular tubes are arranged at an angle, and are used for vibrating rods to pass through the bottom plate.

[0008] By adopting the above technical solution, by fixing the connecting circular tube on the side plate, after the concrete is loaded in the casting space, the vibrating rod passes through the circular tube and is inserted into the concrete near the bottom plate, thereby evenly and comprehensively vibrating and exhausting the concrete at the bottom, reducing the bubbles contained in the concrete, making the concrete more compact, and minimizing the probability of honeycombed surface, thereby maximizing the molding quality and bearing effect of the concrete casting. At the same time, it can also minimize the probability of corrosive substances causing corrosion damage to the interior of the concrete and the steel bars through the honeycombed surface.

[0009] Optionally, a plurality of semicircular membranes are provided at one end of the circular tube close to the base plate, and the semicircular membranes are used to scrape the concrete adhered to the vibrating rod. Each semicircular membrane is provided with a steel wire, one end of the steel wire extends to the inner side of the semicircular membrane, and the other end of the steel wire passes through the semicircular membrane and is embedded in the inner wall of the circular tube.

[0010] By adopting this technical solution, when the vibrating rod is removed after completing the tamping operation, the semicircular membrane scrapes the concrete adhering to the rod, reducing pollution and waste caused by spillage. The steel wire increases the support effect of the circular tube on the semicircular membrane, minimizing excessive wear caused by the semicircular membrane's outward rotation.

[0011] Optionally, a cylinder is provided on the side plate, a slide is provided on the piston rod of the cylinder, the slide is passed through the round tube, the slide is used to close the round tube, a plurality of through holes are opened on the slide, and filter cloths are provided on both sides of the slide.

[0012] By adopting this technical solution, after the vibrating rod completes its work of tamping the concrete at the bottom, the cylinder pushes the slide down and seals the circular tube, thereby reducing the chance of the vibrated concrete spilling out of the tube. Furthermore, the slide is provided with air holes and a filter cloth, which increases the efficiency of removing bubbles from the concrete while ensuring a barrier effect on the concrete.

[0013] Optionally, a pulley is provided at one end of the slide away from the cylinder, the side plate is connected to a roller via a rotating shaft, one end of the filter cloth is fixedly connected to the side plate, the other end of the filter cloth passes around the pulley and is wound around the roller, a ring is provided between the roller and the rotating shaft, and a coil spring is provided inside the ring.

[0014] With this technical solution, the cylinder pushes the slide. As the slide slides downward, the pulley pulls the filter cloth downward. The filter cloth is drawn from the roller, passes around the rotating pulley, and continues downward along with the slide until it contacts the inner wall of the circular tube. At this point, the filter cloth absorbs any concrete remaining in the tube, further reducing concrete waste. When the cylinder's piston rod returns, the filter cloth, acted upon by the coil spring, rewinds around the roller.

[0015] Optionally, an arc-shaped rod is provided between the slide plate and the pulley, the arc-shaped rod has elastic deformation capability, and a middle portion of the arc-shaped rod is bent toward a side away from the casting space.

[0016] By adopting the above technical solution, the cylinder pushes the slide, which in turn drives the curved rod downward, which in turn drives the pulley downward until the pulley contacts the inner wall of the bottom of the circular tube. At this point, because the curved rod has elastic deformation capabilities, the cylinder continues to push the slide, and the curved rod elastically deforms under the drive of the slide. As the middle of the curved rod bends away from the casting space, the pulley, driven by the curved rod, moves the filter cloth toward the casting space. The provision of the curved rod increases the scraping area of the filter cloth against the bottom of the circular tube, improving the efficiency of concrete recovery. Furthermore, the provision of the curved rod increases the sealing area of the filter cloth against the circular tube, increasing the sealing efficiency of the concrete.

[0017] Optionally, an oil-absorbing sponge is provided between the coil spring and the circular ring, an oil pipe is provided on the rotating shaft, one end of the oil pipe is connected to the circular ring, and the other end of the oil pipe extends to the outer periphery of the roller.

[0018] With this technical solution, when the cylinder pushes the slide, the roller releases the filter cloth, the coil spring contracts, and the coil spring squeezes the sponge. The grease absorbed in the sponge is then pumped into the oil pipe. The grease then flows through the pipe and pressure-saturates the filter cloth on the guide wheel. This oil-soaked filter cloth provides a more effective barrier against the concrete. Furthermore, the force generated by the sponge's recovery assists in resetting the coil spring.

[0019] Optionally, one end of the oil pipe close to the roller is buried in the outer periphery of the roller, and the outer peripheral part of the oil pipe protrudes from the outer periphery of the roller, and the part of the oil pipe protruding from the outer periphery of the roller is evenly spaced with oil holes, and sealing strips are fixedly connected to both ends of the filter cloth, and the sealing strips have elastic deformation capabilities.

[0020] By adopting this technical solution, sealing strips are installed at both ends of the filter cloth, minimizing the chance of grease in the filter cloth leaking out of the edges. Furthermore, the oil pipe and sealing strips ensure a certain gap between the filter cloth and the outer periphery of the roller. Furthermore, the portion of the oil pipe protruding from the outer periphery of the roller is provided with oil holes at even intervals, allowing grease in the pipe to fully penetrate the filter cloth.

[0021] Optionally, an arcuate groove is provided on one side of the sealing strip, and a convex ridge is fixedly connected to the other side of the sealing strip, and the convex ridge is snap-fitted with the arcuate groove.

[0022] By adopting the above technical solution, when the sealing strip is wound around the roller, the ridges and the arc grooves are gradually engaged with each other, so that the filter cloth is neat and orderly, further reducing the probability of affecting the sealing of the filter cloth edge due to misalignment of the sealing strip.

[0023] Optionally, protrusions are symmetrically arranged in the oil pipeline, the protrusions are arc-shaped and elastic, and a small ball is arranged in the oil pipeline through a tension spring.

[0024] By adopting the above technical solution, when the grease passes through the symmetrically arranged protrusions, the grease is accelerated and forms turbulence, and the grease pushes the small balls, which continuously stretch and swing the springs, thereby increasing the vibration dredging effect on the oil pipeline and reducing the probability of blockage of the oil delivery holes of the oil pipeline.

[0025] Optionally, the protrusion is hollow and connected to the oil delivery hole through an exhaust pipe. The small ball is a magnetic ball. A magnetic block is provided in the oil delivery pipe, and the small ball and the magnetic block repel each other.

[0026] By adopting the above technical solution, when the grease passes through the protrusion, the protrusion is squeezed, and the airflow generated by the squeezing of the protrusion has the effect of clearing the oil delivery hole, further reducing the probability of the oil delivery hole being blocked.

[0027] The ball continuously expands and contracts with the tension spring. When the ball passes through the magnetic block, it is repelled and impacts the oil hole, increasing the fluid pressure in the oil hole at the corresponding position, further unblocking the oil hole and keeping it unobstructed, thereby allowing the grease to evenly soak the filter cloth.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By connecting the circular tube to the side plate, the operator passes the vibrator through the circular tube directly to the concrete near the bottom plate. The vibrator evenly and comprehensively tampers the concrete at the bottom to exhaust air, reducing bubbles in the concrete, making the concrete more dense, and minimizing the chance of honeycombing. This improves the molding quality and load-bearing effect of the concrete casting, that is, improves the quality of the concrete;

[0030] 2. By setting up the cylinder, slide plate, filter cloth and roller, after the vibrating rod completes the tamping work of the concrete at the bottom, the cylinder pushes the slide plate down and closes the round tube, thereby reducing the probability of the vibrated concrete overflowing from the round tube. The plate is provided with air holes, and the filter cloth is provided on the slide plate, which increases the efficiency of removing bubbles in the concrete while ensuring the blocking effect on the concrete;

[0031] 3. By installing a ring and coil spring on the roller, and filling the gap between the coil spring and the ring with an oil-absorbing sponge, and installing an oil pipe on the rotating shaft, the roller releases the filter cloth, the coil spring contracts, and the coil spring squeezes the sponge. The oil absorbed in the sponge is then pumped into the oil pipe. The oil passes through the oil pipe and pressure-infiltrates the filter cloth on the guide wheel. This oil-infiltrated filter cloth is more effectively isolated from the concrete. At the same time, the force generated by the sponge's recovery assists in resetting the coil spring.

The three semicircular membranes 310 are arranged in sequence along the axial direction of the circular tube 200. The semicircular membranes 310 have a certain elastic deformation capacity. The inner circumference of the semicircular membranes 310 bends toward the direction close to the third side plate 123. The thickness of the semicircular membranes 310 gradually decreases from the end close to the inner wall of the circular tube 200 to the end away from the circular tube 200. A steel wire 320 is fixedly connected to the inner circumference of each semicircular membrane 310. One end of the steel wire 320 extends to the inner side of the semicircular membrane 310.

[0045] Reference Figure 2 A cylinder 410 is hingedly connected to the side of the third side plate 123 facing away from the casting space 140. Cylinder 410 is vertically mounted and positioned directly above the circular tube 200. A slide 420 is hingedly connected to the piston rod of cylinder 410. Slide 420 is vertically mounted and extends through the circular tube 200 to seal the circular tube 200. Slide 420 defines through-holes 421, which are spaced apart along its length.

One end of the filter cloth 450 is fixedly connected to the third side plate 123, and the other end of the filter cloth 450 passes around the pulley 440 and is wound around the roller 520.

[0048] Reference Figure 4 and Figure 5 A ring 530 is fixedly connected between the rotating shaft 510 and the roller 520. One end of the ring 530 is fixedly connected to the roller 520, and the other end of the ring 530 is sealed with an end cap 540. The rotating shaft 510 passes through the end cap 540 and is rotatably connected to the end cap 540. A coil spring 550 is sleeved inside the ring 530. One end of the coil spring 550 is fixedly connected to the rotating shaft 510, and the other end of the coil spring 550 is fixedly connected to the inner wall of the ring 530.

[0049] Reference Figure 4 and Figure 6 Sealing strips 451 are fixedly connected to both sides of the filter cloth 450. One side of the sealing strip 451 has an arcuate groove 452, and the other side of the sealing strip 451 has a ridge 453 fixedly connected to it. The ridge 453 engages with the arcuate groove 452. When the sealing strip 451 is wound around the roller 520, the ridge 453 gradually engages with the arcuate groove 452, keeping the filter cloth 450 neat and orderly.

[0050] Reference Figure 4 and Figure 5 The rotating shaft 510 has a first hole 511 defined along its axial direction and a second hole 512 defined along its circumference. The second hole 512 communicates with the first hole 511, which in turn communicates with the interior of the ring 530. The gap between the coil spring 550 and the ring 530 is filled with an oil-absorbing sponge. An oil delivery pipe 600 is sheathed within the first hole 511 of the rotating shaft 510 and communicates with the first hole 511 of the rotating shaft 510. The oil delivery pipe 600 is rotatably connected to the rotating shaft 510, and the other end of the oil delivery pipe 600 extends to the outer circumference of the roller 520. One end of the oil pipe 600 extending to the periphery of the roller 520 is partially buried in the roller 520, and the oil pipe 600 partially protrudes from the periphery of the roller 520. The oil pipe 600 protruding to the periphery of the roller 520 is provided with oil holes 610, and the oil holes 610 are arranged in sequence along the length direction of the oil pipe 600.

[0051] Reference Figure 7 A protrusion 620 is symmetrically fixedly connected to the inner wall of the oil pipe 600 near the oil delivery hole 610. The protrusion 620 is curved and hollow, and has elastic deformation capabilities. The protrusion 620 on the side away from the oil delivery hole 610 is fixedly connected to a small ball 640 via a tension spring 630. The small ball 640 is a magnetic ball. A hemispherical magnet 650 is fixedly connected to the inner wall of the oil pipe 600 on the side away from the oil delivery hole 610, and the magnet 650 and the small ball 640 repel each other. The protrusion 620 on the side near the oil delivery hole 610 is fixedly connected to an exhaust pipe 660, which is connected to the oil delivery hole 610.

[0052] The implementation principle of a concrete construction formwork structure for reducing honeycombed surfaces according to an embodiment of the present application is as follows: an operator places a bottom plate 110 horizontally on the ground, vertically installs a first side plate 121 on both sides of the bottom plate 110, and horizontally installs a second side plate 122 on the end of the first side plate 121 away from the bottom plate 110, with the second side plate 122 located directly above the bottom plate 110. The operator vertically installs a third side plate 123 on the end of the second side plate 122 away from the first side plate 121. The operator then vertically installs the end plates 130 on both ends of the bottom plate 110. The bottom plate 110, the first side plate 121, the second side plate 122, the third side plate 123, and the end plates 130 surround and form an inverted T-shaped pouring space 140, and the operator pours cement into the pouring space 140.

[0053] After the operator pours a certain amount of cement into the pouring space 140, the operator inserts the vibrator into the pouring space 140 through the circular tube 200. The vibrator is inserted into the cement near the bottom plate 110 and the concrete is vibrated evenly and comprehensively to exhaust the air and reduce the bubbles contained in the concrete.

[0054] After the vibrating rod completes its vibrating work, the operator pulls the vibrating rod out of the circular tube 200. The semicircular membrane 310 inside the circular tube 200 scrapes the concrete adhering to the vibrating rod, reducing the pollution and waste caused by spillage of concrete. The elastic steel wire 320 provides increased support for the vibrating rod and reduces excessive wear caused by the outward rotation of the semicircular membrane 310.

[0055] After the operator removes the vibrating rod from the circular tube 200, the operator activates the air cylinder 410, which pushes the slide plate 420 downward. The slide plate 420 then drives the curved rod 430 downward, which in turn drives the pulley 440 downward until the pulley 440 contacts the inner wall of the bottom of the circular tube 200. At this point, because the curved rod 430 has elastic deformation capability, the air cylinder 410 continues to push the slide plate 420. The curved rod 430 elastically deforms under the drive of the slide plate 420. As the middle portion of the curved rod 430 bends toward the side away from the third side plate 123, the pulley 440, driven by the curved rod 430, drives the filter cloth 450 toward the side closer to the casting space 140. When the slide plate 420 slides down, the pulley 440 pulls the filter cloth 450 downward. The filter cloth 450 is drawn out from the roller 520 and passes around the outer periphery of the rotating pulley 440 and extends downward along with the slide plate 420 until the filter cloth 450 abuts against the inner wall of the circular tube 200.

[0056] The cylinder 410, slide 420, curved rod 430, pulley 440, and gauze seal the circular tube 200, reducing the chance of concrete spilling out of the tube 200 after vibrating. The filter cloth 450 absorbs any concrete remaining in the circular tube 200, further reducing concrete waste. The curved rod 430 increases the scraping area of the filter cloth 450 against the bottom of the circular tube 200, improving concrete recovery efficiency. Furthermore, the provision of the curved rod 430 increases the sealing area of the filter cloth 450 against the circular tube 200, enhancing the sealing efficiency of the concrete.

[0057] The gauze is reset by the coil spring 550, and an oil-absorbing sponge is embedded in the coil spring 550. When the roller 520 releases the filter cloth 450, the coil spring 550 reels and squeezes the sponge. The grease in the sponge is filled into the oil pipe 600 after passing through the No. 2 hole 512 and the No. 1 hole 511. The grease in the oil pipe 600 seeps out from the oil hole 610 and pressure-lubricates the filter cloth 450 on the roller 520. The grease is used to increase the isolation effect between the filter cloth 450 and the concrete.

[0058] As grease enters oil pipe 600 and seeps out of oil hole 610, it first passes through symmetrically arranged protrusions 620. As the grease passes through protrusions 620, the cross-sectional area of the grease's path decreases, accelerating the grease and creating turbulent flow. The grease pushes against ball 640 and the spring, causing ball 640 to continuously expand and oscillate with spring 630, further enhancing the vibration-clearing effect on oil hole 610 and reducing the likelihood of blockage. As ball 640 continuously expands and contracts with spring 630 and passes through magnet 650, it is repelled and impacts the corresponding oil hole 610, increasing the fluid pressure within that hole and further clearing it.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
