Description

Technical Field

[0001] The invention relates to the technical field of basement building construction, and in particular to a basement wallboard waterproof concrete construction device and a method thereof. Background Art

[0002] Waterproof concrete, also known as structural self-waterproof concrete, is a kind of concrete with high anti-seepage performance. By adjusting the mix ratio of concrete or adding admixtures, steel fibers, synthetic fibers, etc., the void ratio inside the concrete can be reduced or the pore shape and distribution characteristics can be changed to achieve the purpose of waterproofing (anti-seepage). Waterproof concrete is mainly used in underground projects of industrial and civil buildings, such as basements, underground ditches, traffic tunnels, urban subways, pools, water towers, bridge piers, seaports, docks, dams and other projects and structures that are often subjected to pressurized water.

[0003] In the construction process of waterproof concrete for basement wall panels, due to construction needs or structural requirements, it may be necessary to pour concrete in sections, thus forming construction joints. These construction joints are the bonding surfaces between new and old concrete and need to be roughened. By roughening, the roughness of the concrete surface can be significantly improved, thereby enhancing the bonding force between new and old concrete, preventing the formation of water seepage channels, and improving waterproof performance.

[0004] When traditional roughening equipment is in operation, the dust generated is handled by an external dust suction device. Although the two work synchronously, they use two different driving sources under normal circumstances, which consumes a lot of energy and the suction force cannot be guaranteed.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0021] See also Figure 1-8 The present invention discloses a basement wallboard waterproof concrete construction device and method, comprising a device housing 1, wherein the device housing 1 is equipped with a wheel set and a moving handle, wherein the matched wheel set can roll along the surface of the construction joint, and the moving handle is a gripping position for construction personnel to control the movement of the device housing 1, wherein a support frame 11 is horizontally installed at a lower position inside the device housing 1, and a limiting sleeve 12 is fixedly arranged at equal distances inside the support frame 11, and the inner wall of the limiting sleeve 12 is smooth and made of high-strength steel; A driving motor 18 is installed at the top of the device housing 1. A crankshaft 13 is installed through a shaft sleeve inside the device housing 1 and directly above the support frame 11. A driven wheel 17 is fixedly installed at the center of the crankshaft 13. The driving wheel of the driving motor 18 is connected to the driven wheel 17 through a belt. When the driving motor 18 is started, the driven wheel 17 is driven to rotate through the belt after the driving motor 18 works, and the crankshaft 13 rotates following the driven wheel 17. A driving arm 14 is rotatably installed on the connecting rod journal of the crankshaft 13. The driving arm 14 rotates relative to the connecting rod journal while following the rotation of the crankshaft 13. A piston cylinder 15 is rotatably installed at the end of the driving arm 14, and the piston cylinder 15 is inserted into the limiting sleeve 12 along the vertical direction. The driving arm 14 reciprocates in the vertical direction to apply an extrusion force to the piston cylinder 15, so that the piston cylinder 15 reciprocates up and down in the limiting sleeve 12. Chisel heads 16 are fixedly installed at the bottom of several limiting sleeves 12, and the chisel heads 16 move together with the piston cylinder 15. When the chisel heads 16 come into contact with the concrete base surface of the construction joint, they impact it, and part of the concrete base surface is crushed to achieve the effect of roughening. Dust collecting parts 2 are arranged on both sides of the device housing 1, and the dust collecting parts 2 absorb the dust generated during roughening and remove the debris from the concrete base surface. The dust collecting part 2 includes a driving gear 21 concentrically fixed at both ends of the crankshaft 13. The driving gear 21 rotates together with the crankshaft 13, and the two rotate at the same speed. A driven gear 22 is meshed on one side of the driving gear 21. When the driving gear 21 rotates, the driven gear 22 rotates with it. A rotating shaft 20 is installed at the center of one side of the driven gear 22, and the rotating shaft 20 is installed on both sides of the device housing 1 through a shaft seat. When the driven gear 22 rotates, the rotating shaft 20 rotates in the shaft seat inside the device housing 1. The contact surface of the driving gear 21 and the driven gear 22 is coated with lubricating grease. When the two rotate, the lubricating grease forms a lubricating film on the surface of the driving gear 21 and the driven gear 22 to reduce the friction loss and wear of the two. The diameter of the driving gear 21 is larger than the diameter of the driven gear 22, and the transmission ratio is less than 1, which increases the rotation speed of the driven gear 22. A dust collecting tube shell 23 is arranged along the axial direction of the driven gear 22, and the dust collecting tube shell 23 is fixedly connected to the side wall of the device housing 1 through a positioning rod. A turbine blade 24 is installed inside the dust collecting tube shell 23, and a filter is arranged near the turbine blade 24 in the turbine blade 24. A synchronous shaft 25 is fixedly installed at a central position on one side of the turbine blade 24, and the synchronous shaft 25 penetrates the dust collecting tube shell 23 and is fixedly connected to the center position of the end face of the driven gear 22. The synchronous shaft 25 rotates together with the driven gear 22, thereby driving the turbine blade 24 to rotate at a high speed in the dust collecting tube shell 23. The turbine blade 24 sucks the surrounding air into the dust collecting tube shell 23 and forms a high-speed airflow, which forms a low-pressure area inside the dust collecting tube shell 23. A U-shaped tube 26 is connected to the air inlet of the dust collection tube shell 23, and a straight tube 27 is horizontally placed on the inner side of the device shell 1, and the straight tube 27 is connected to the U-shaped tube 26. The bottom of the straight tube 27 is provided with through holes at equal distances along its path, and a branch tube 28 is connected to the bottom of the straight tube 27 and at a position overlapping with the through hole, and the tails of several branch tubes 28 are connected to hoses 29. A channel is formed among the U-shaped tube 26, the straight tube 27, the branch tube 28 and the hose 29 to be connected to the dust collection tube shell 23, and the hose 29 is facing the surface of the construction joint. The above-mentioned low-pressure area will attract the dust generated by chiseling and make it be sucked into the dust collection tube shell 23, so as to realize the synchronous collection of chiseling dust, and share the same driving source with the chiseling, so as to be more energy-efficient.

[0022] like Figure 1-Figure 3 As shown, further, a vertical tube 231 is provided at the center of the bottom of the dust collection tube shell 23, and a dust collecting tank 232 is threadedly connected to the end of the vertical tube 231. The dust collecting tank 232 is used to collect the inhaled dust, and the dust stored in the dust collecting tank 232 can be cleaned by rotating it.

[0023] In another embodiment, see Figure 2-Figure 4A reducer 41 is installed on the inner side of the device housing 1 through a support frame. The reducer 41 can be one of the planetary reducers. The input end of the reducer 41 is concentrically connected to the rotating shaft 20, and the reducer 41 is coaxial with the rotating shaft 20. The output end of the reducer 41 is connected to a reciprocating screw 43, and the end of the reciprocating screw 43 is inserted into the shaft frame 42. The shaft frame 42 is fixed to the inner side of the device housing 1. The outer ring of the reciprocating screw 43 is matched with a reciprocating sleeve 44. A connecting rod 45 is welded at one end surface of the reciprocating sleeve 44. The end of the connecting rod 45 is connected to an open sleeve 46, and the open sleeve 46 is sleeved on the outer wall of the straight tube 27. Since the horizontal heights of the end surfaces of the two ends of the open sleeve 46 are lower than the horizontal center position of the straight tube 27, the reciprocating sleeve 44 cannot rotate relative to the reciprocating screw 43 due to the limit of the open sleeve 46. An L-shaped rod 47 is welded to the outer wall of the open sleeve 46, and a square tube 48 is installed at the tail of the L-shaped rod 47. A brush head 49 is installed at an equal distance at the bottom of the square tube 48. The brush head 49 is a kind of wire brush. In static state, the brush head 49 contacts the construction joint. During specific operation, when the rotating shaft 20 rotates, the reciprocating screw 43 is driven to rotate on the shaft frame 42 through the speed reducer 41, and the reciprocating sleeve 44 reciprocates on the reciprocating screw 43. The open sleeve 46 slides back and forth along the outer wall of the straight tube 27. The brush head 49 moves together with the open sleeve 46 under the action of the square tube 48 and the L-shaped rod 47, so that the brush head 49 brushes the roughening area back and forth, and removes the debris generated by the roughening on its surface, further improving the cleanliness of the surface of the construction joint after roughening. At the same time, this process is also performed synchronously with the roughening process, sharing the same driving source, and is more energy-efficient.

[0024] Among them, the inner wall of the open sleeve 46 is embedded with steel balls, and a number of the steel balls are in contact with the outer wall of the straight tube 27 but not connected. When the open sleeve 46 slides back and forth along the outer wall of the straight tube 27, the steel balls roll at the connection between the two to reduce the wear between the two. After the steel balls are embedded, it is also necessary to ensure that the horizontal heights of the end surfaces of both ends of the open sleeve 46 are lower than the horizontal center position of the straight tube 27. It should be noted that the horizontal heights of the end surfaces of both ends of the open sleeve 46 are lower than the horizontal center position of the straight tube 27, which only represents one of the connection methods of the open sleeve 46 and the straight tube 27. It can also be connected in the form of bumps and grooves. In another embodiment, see Figure 2-Figure 7A cross bar 51 is installed on the inner side of the device housing 1, and a movable sleeve 52 is sleeved on the outer wall of the cross bar 51. A rectangular hole 481 is opened on the side of the square tube 48 facing the cross bar 51. A paddle plate 53 is fixedly connected to one end of the outer wall of the movable sleeve 52, and the paddle plate 53 is horizontally inserted in the rectangular hole 481. A flat plate 54 is connected to the other end of the outer wall of the movable sleeve 52. Round rods 55 are arranged at equal distances on the end surface of the flat plate 54 facing one end of the hose 29. A U-shaped plate 56 is installed at the end of the round rod 55, and the U-shaped plate 56 is inserted into the outer wall of the hose 29, and the U-shaped plate 56 is close to the end of the hose 29. When working, the square tube 48 is reciprocated and moved horizontally. When the rectangular hole 481 moves relative to the paddle plate 53, after moving a certain distance, the inner wall of the rectangular hole 481 contacts the paddle plate 53 and drives it to move together, that is, the paddle plate 53 reciprocates under the pressure of the inner wall of the rectangular hole 481, and the reciprocating motion stroke of the paddle plate 53 is reduced through the intermittent contact between the rectangular hole 481 and the paddle plate 53. After the paddle plate 53 reciprocates, it drives the movable sleeve 52 to slide back and forth on the outer wall of the cross bar 51, thereby driving the several U-shaped plates 56 on one side of the flat plate 54 to reciprocate the bottom of the hose 29, causing the hose 29 to deflect back and forth, thereby increasing the adsorption area of ​​the hose 29 and improving the dust collection effect.

[0025] In the device housing 1, the piston cylinder 15 and the chisel head 16 are fixed by high-strength bolts, and the two are detachable. When the chisel head 16 is damaged, the chisel head 16 can be replaced in time.

[0026] Furthermore, the hose 29 and the branch pipe 28 are fixedly connected by a clamp. When the hose 29 is damaged, it can be replaced by removing the clamp. In addition, the inner walls of several hoses 29 are provided with filter screens to filter large particles of impurities. Debris or large particles of impurities are removed by the brush head 49.

[0027] In this embodiment, Figure 1-Figure 3 As shown, the relative device housing 1 of the driving gear 21 and the driven gear 2 and other structures is exposed to the outside. In actual production, a protective shell is provided on the outside of the device housing 1 to protect the driving gear 21 and the driven gear 2 and other structures. In addition, the present invention also provides a basement wall slab waterproof concrete construction method, the basement wall slab waterproof concrete construction method specifically comprises the following steps: S1. Surface cleaning: clean the floating slurry, loose stones, debris, etc. on the surface of the construction joint connected to the basement wall panel to expose the concrete base surface of the construction joint; S2, roughening treatment: move the device housing 1 to the concrete base surface treated in S1, start the drive motor 18 to control a plurality of chisel heads 16 to reciprocate up and down, hit the concrete base surface for roughening treatment, and absorb the dust generated by the roughening treatment, and scrape off the debris on the concrete base surface; S3, flushing and moistening: After S2 treatment is completed, the surface of the concrete base is rinsed with clean water to remove residual debris and dust, and keep the surface moist; S4. Laying mortar: Lay a layer of cement mortar or interface treatment agent on the surface of the construction joint after roughening and washing. If it is cement mortar, its thickness should be kept at 20-25mm; S5. Wall panel pouring: After S4 is completed, set up the formwork and pour the wall panel waterproof concrete. After the wall panel waterproof concrete is completely dry, remove the formwork.

[0028] S6. Natural curing: Cover the surface of the waterproof concrete with any of the following moisturizing materials: wet cloth, straw mat, or sack. Then, on the basis of this moisturizing covering, water it regularly for natural curing. The number of days for natural curing shall not be less than 14 days.
