Description

Technical Field

[0001] This invention relates to the technical field, and specifically to a single-mesh telescopic chiseling end bracket for chiseling operations on multiple construction surfaces of beams. Background Technology

[0002] In beam construction, roughening the multiple construction surfaces of beams and slabs is a crucial process for ensuring the strength of subsequent structural connections. Existing roughening methods largely rely on scattered roughening tools or fixed frame equipment, which has significant shortcomings: Firstly, traditional equipment struggles to achieve modular assembly, requiring individual adjustments for different construction surfaces, resulting in low construction efficiency and an inability to quickly create a uniform roughening surface. Secondly, the lack of precise guiding and positioning structures in the initial roughening stage easily leads to uneven distribution and uncontrolled density of roughening points, which not only damages the beam and slab thickness during subsequent roughening but may also increase the difficulty due to dispersed local pressure. Furthermore, existing equipment tends to exert a uniform impact on the beam and slab during operation, making it difficult to control the local roughening force, potentially causing damage to non-construction areas. The resulting pits often exhibit significant positional deviations and inconsistent sizes and depths, affecting the quality of subsequent construction. Therefore, there is an urgent need for a multi-construction surface roughening device for beams that can achieve rapid installation, precise positioning, locally controllable roughening, and guaranteed roughening quality. Summary of the Invention

[0003] In order to solve the above-mentioned problems in the existing technology, the present invention aims to provide a single-net telescopic chiseling end bracket for chiseling operations on multiple construction surfaces of beams.

[0004] The technical solution adopted in this invention is as follows: A single-mesh telescopic chiseling end bracket for multi-face chiseling operations on beams includes a support plate controlled by a control cylinder and used to support a control plate; multiple sliders slidably disposed on the control plate and divided into several groups; multiple chains located between the beam and the control plate and connected to each group of sliders; multiple anchors corresponding to the multiple sliders and connected to the corresponding chains; and multiple chiseling mesh plates detachably mounted on the anchors and in contact with the beam's construction surface. Multiple chiseling ends are fixedly provided at one end of each chiseling mesh plate near the beam. Two opposite sides of each chiseling mesh plate are provided with irregularly shaped holes. In each group of sliders, the irregularly shaped holes on any two adjacent chiseling mesh plates engage with the corresponding anchors to form a connection. The chains corresponding to adjacent sliders but not in the same group are hinged together. Sliding is allowed between any two chiseling mesh plates. As a preferred embodiment of the present invention, a vibration module is provided on the side of the control plate away from the beam, a plurality of limiting grooves are provided on the side of the control plate, and a plurality of pressure columns are fixedly provided on the side of the control plate close to the beam, with each of the plurality of pressure columns corresponding to a plurality of the roughened mesh plates. As a preferred embodiment of the present invention, the anchor includes two connecting rods, a connecting pin connecting the two connecting rods, a plug rod fixedly connected to the two connecting rods respectively, and two limiting frames fixedly connected to the two plug rods respectively. The ends of the two connecting rods that are far apart from each other respectively form a male connecting head and a female connecting head. In two adjacent anchors, the male connecting head of one anchor is hinged to the female connecting head of the other anchor. As a preferred embodiment of the present invention, each of the anchors and the chiseled mesh plate is provided with two latches that are hinged to each other by a rotating shaft. The two latches form a groove on the side that is close to each other. The groove cooperates with the plug rod. The two latches are respectively connected to two adjacent chiseled mesh plates corresponding to the sliders in the same group by bolts. As a preferred embodiment of the present invention, the irregular hole is a 1 / 2 square hole. The two adjacent chisel mesh plates corresponding to the sliders in the same group cooperate to form a complete anchor hole. The inner side wall of the anchor hole near the beam is smooth and cooperates with the plug rod. The inner side wall of the anchor hole away from the beam diverges into a countersunk structure to form an installation part. The limiting frame is located in the installation part and is limited by the buckle. As a preferred embodiment of the present invention, the control plate is provided with a plurality of mounting slots penetrating the control plate, and an extension plate is fixedly provided at one end of the slider near the beam. The extension plate is slidably disposed within the mounting slots, the height of the extension plate is greater than the thickness of the control plate, and a connecting plate is fixedly provided at one end of the extension plate away from the slider. A tow hook is slidably provided at one end of the connecting plate near the beam. As a preferred embodiment of the present invention, the tow hook is connected to the slider via a strong spring located inside the extension plate, and the end of the tow hook away from the slider is connected to one section of the corresponding chain. A connecting ring is provided on a section of the chain, and the connecting ring cooperates with the corresponding connecting pin. As a preferred embodiment of the present invention, the control plate is provided with a plurality of sliding grooves on the side away from the beam, and a traction block is slidably provided in each sliding groove. A fixing plate is fixedly provided on the side of the traction block near the slider. A trapezoidal block is fixedly provided at the end of the fixing plate away from the traction block. The inclined surface of the trapezoidal block cooperates with the slider. A traction buckle is fixedly provided at the end of the traction block away from the beam. As a preferred embodiment of the present invention, the end of the plug rod away from the connecting rod forms a movable end, the shape and size of which are the same as those of the chiseling end. As a preferred embodiment of the present invention, the beam has multiple construction surfaces, all of which are provided with the roughened mesh plate, the anchor and the chain. Two adjacent construction surfaces are perpendicular to each other and are separated by a frame, and the frame is provided with multiple protrusions corresponding to the roughened mesh plate.

[0005] The beneficial effects of this invention are as follows: This invention is a single-mesh telescopic chiseling end support for multi-face chiseling operations on beams. The chiseling mesh plate is a unit module, which is connected in series by chains and then in parallel by anchors to form a chiseling mesh chain. It can be quickly laid and used for uniform chiseling of beams and slabs. In the initial stage of chiseling, the vibration of the plate can be controlled to form chisel points of a certain depth on the construction surface of the beam and slab. The chisel points have a guiding and positioning effect on subsequent chiseling. The thickness of the beam and slab will not be damaged due to the dense chisel points during subsequent chiseling. During the formal chiseling process, the beam and slab are only subjected to local stress, which will not damage the beam and slab. Moreover, the concentrated pressure makes it easier to chisel. In addition, since the chisel points are positioned in the initial chiseling stage, a single-layer grid-like distribution of pits will be formed after the construction surface is chiseled. The pits are uniform in position and have similar size and depth. Attached Figure Description

[0008] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0009] Combination Figures 1-10 A single-mesh telescopic chiseling end bracket for multi-face chiseling operations on beams includes a support plate 18 controlled by a control cylinder 19 and used to support a control plate 13; multiple sliders 15 slidably disposed on the control plate 13 and divided into several groups; multiple chains 16 located between the beam and the control plate 13 and respectively connecting each group of sliders 15; multiple anchors 21 corresponding one-to-one with the multiple sliders 15 and connected to the corresponding chains 16; and multiple chiseling mesh plates 11 detachably installed on the anchors 21 and in contact with the beam construction surface. The control cylinder 19 can be a hydraulically driven hydraulic cylinder or an electrically driven servo cylinder. When a servo cylinder is selected, a suitable power supply method can be selected according to the environment of the beam yard. For example, in beam yards located in open areas, wind power generation or solar power generation can be introduced to power the control cylinder 19.

[0010] The roughening mesh plate 11 is fixedly provided with multiple roughening ends 30 at one end near the beam. Two opposite sides of the roughening mesh plate 11 are respectively provided with irregularly shaped holes 27. In each group of sliders 15, the irregularly shaped holes 27 on any two adjacent roughening mesh plates 11 engage with the corresponding anchors 21 to form a connection. The chains 16 corresponding to adjacent sliders 15 but not in the same group are hinged to each other. Sliding is allowed between any two roughening mesh plates 11. The roughening mesh plates 11, as unit modules, are connected in series by chains 16 and then in parallel via anchors 21, forming a roughening mesh chain with a certain number of plates, allowing for rapid installation and uniform roughening construction.

[0011] Advantageously, a vibration module 25 is provided on the side of the control plate 13 away from the beam, and multiple limiting grooves 22 are provided on the side of the control plate 13. Multiple pressure columns 12 are fixedly provided on the side of the control plate 13 closer to the beam, and the multiple pressure columns 12 correspond one-to-one with the multiple chiseling mesh plates 11. In the initial stage of chiseling, the pressure columns 12 enable the chiseling mesh chain and the beam plate to quickly form a cooperation and accurately locate the chiseling position. The vibration module 25 can be a device that can generate vibration, such as a vibration motor. The vibration is not limited to vertical vibration. When there is also horizontal vibration, limiting rods can be added around the beam to cooperate with the limiting grooves 22 to limit the vibration range of the control plate 13.

[0012] Advantageously, the anchor 21 includes two connecting rods 28, a connecting pin 32 connecting the two connecting rods 28, a plug-in rod 34 fixedly connected to the two connecting rods 28 respectively, and two limiting frames 35 fixedly connected to the two plug-in rods 34 respectively. The ends of the two connecting rods 28 that are far apart from each other form a male connector 31 and a female connector 33 respectively. In two adjacent anchors 21, the male connector 31 of one anchor 21 is hinged to the female connector 33 of the other anchor 21. The male connector 31 and the female connector 33 are used to connect two adjacent roughened mesh plates together, and the diameter of the male connector 31 is slightly smaller than the inner diameter of the female connector 33.

[0013] Advantageously, each anchor 21 and the roughened mesh plate 11 is provided with two latches 20 that are hinged to each other by a rotating shaft 38. The side of the two latches 20 that are close to each other forms a slot 37, which cooperates with the plug rod 34. The two latches 20 are respectively connected to two adjacent roughened mesh plates 11 of the same group of sliders 15 by bolts. The latches 20 are fitted in pairs into a butterfly shape, allowing folding in the middle, and connecting two roughened mesh plates 11 on each side.

[0014] Advantageously, the irregular hole 27 is a 1 / 2 square hole. The two adjacent roughened mesh plates 11 of the slider 15 in the same group cooperate to form a complete anchor hole. The inner wall of the anchor hole near the beam is smooth and cooperates with the plug rod 34. The inner wall of the anchor hole away from the beam diverges into a countersunk structure to form an installation part. The limiting frame 35 is located in the installation part and is limited by the buckle 20.

[0015] Advantageously, the control plate 13 is provided with multiple mounting slots 24 penetrating the control plate 13. An extension plate 42 is fixedly provided at one end of the slider 15 near the beam. The extension plate 42 penetrates and slides within the mounting slots 24. The height of the extension plate 42 is greater than the thickness of the control plate 13. A connecting plate 43 is fixedly provided at one end of the extension plate 42 away from the slider 15. A tow hook 45 is slidably provided at one end of the connecting plate 43 near the beam. The tow hook 45 has a built-in spring buckle, which can keep it from falling off after being connected to the chain 16.

[0016] Advantageously, the tow hook 45 is connected to the slider 15 via a strong spring located inside the extension plate 42. The end of the tow hook 45 away from the slider 15 is connected to a corresponding section of the chain 16. A connecting ring 44 is provided on a portion of the chain 16, and the connecting ring 44 engages with a corresponding connecting pin 32. The connecting ring 44 is obtained by post-processing the chain 16, and is welded to a specific position on the chain 16.

[0017] Advantageously, the control plate 13 has multiple grooves 23 on the side away from the beam, and a traction block 14 is slidably mounted in each groove 23. A fixing plate 40 is fixed to the side of the traction block 14 near the slider 15. A trapezoidal block 39 is fixed to the end of the fixing plate 40 away from the traction block 14, and the inclined surface of the trapezoidal block 39 cooperates with the slider 15. A traction buckle 41 is fixed to the end of the traction block 14 away from the beam. The traction block 14 needs to be used with an external power source, preferably a winch that moves the steel cable to drive the traction block 14.

[0018] Advantageously, the end of the plug rod 34 furthest from the connecting rod 28 forms a movable end 36, the shape and size of which are the same as those of the chiseling end 30. The plug rod 34 also has the same chiseling function.

[0019] Advantageously, the beam has multiple construction surfaces, all of which are equipped with the chiseling mesh plate 11, the anchor 21, and the chain 16. Adjacent construction surfaces are perpendicular to each other and separated by a frame 17, which has multiple protrusions corresponding to the chiseling mesh plate 11. The chiseling support structure required for the construction surfaces on the sides of the beam is based on the same principle as that for the horizontal surfaces; the attached diagram only highlights the structures related to the horizontal construction surfaces for ease of illustration. The frame 17 is also equipped with sensors, ultrasonic emission, and ultrasonic detection modules. Ultrasonic rebound is used to detect the surface strength of the target beam plate, and the detection results are fed back to the control module to control the speed and frequency of the winch winding the steel rope, allowing the moving speed and cycle of the traction block 14 to be adaptively adjusted, thereby ensuring the chiseling mesh chain has a suitable chiseling frequency and pressure.

[0020] The working principle of this invention is as follows: In the initial state, after the beam is poured, it is placed in parallel with the non-construction surface facing down. According to the size of the beam, the chain 16 is connected in series with a suitable number of anchors 21 of the roughened mesh plate 11, and then the anchors 21 are connected in parallel to form a roughened mesh chain. The frame 17 is placed in place as the skeleton for installation, and the roughened mesh chain and control plate 13 are installed on all construction surfaces.

[0021] During the initial chiseling stage, the control cylinder 19 controls its piston rod to slowly retract as the chiseling progresses. When the support plate 18 is not in contact with the control plate 13, the vibration module 25 is activated to make the control plate 13 vibrate. The control plate 13 transmits the vibration to all the chiseling mesh plates 11 through the pressure column 12. The chiseling end 30 vibrates together with the chiseling mesh plate 11, gradually forming a pit on the construction surface of the beam and slab. As the piston rod of the control cylinder 19 retracts, the vibration range of the control plate 13 gradually increases, eventually forming chisel points of a certain depth on the construction surface of the beam and slab. The chisel points have a guiding and positioning effect on the subsequent chiseling, and the thickness of the beam and slab will not be damaged due to the dense chisel points during subsequent chiseling.

[0022] When the actual chiseling begins, the control cylinder 19 controls its piston rod to extend to a certain height, the support plate 18 lifts the control plate 13, the pressure column 12 no longer contacts the chiseling mesh plate 11, during this process the extension plate 42 and the control plate 13 slide, the slider 15 does not rise with the control plate 13, and finally a small gap is left between the slider 15 and the control plate 13, and the strong spring is in normal condition.

[0023] The winch is started, and the traction block 14 is controlled to slide back and forth in the slide groove 23 via the steel cable. The trapezoidal block 39 and the fixed plate 40 move together with the traction block 14. The inclined surface of the trapezoidal block 39 contacts the gap between the slider 15 and the control plate 13, stretching the strong spring and lifting the slider 15 relative to the control plate 13. When the traction block 14 passes the corresponding slider 15, the trapezoidal block 39 and the slider 15 no longer contact each other, and the slider 15 returns to its original position under the elastic force of the strong spring. The slider 15 vibrates during the resetting process and returns to its normal state after multiple compressions and stretches. During the compression process, the gap between the slider 15 and the control plate 13 disappears.

[0024] The up-and-down reciprocating oscillation of slider 15, extension plate 42, connecting plate 43, strong spring and tow hook 45 is transmitted to the corresponding target anchor 21. The vibration of the target anchor 21 will cause the chiseling mesh plate 11 directly connected to it to vibrate. The chiseling mesh plate 11 adjacent to the target does not vibrate or only vibrates slightly.

[0025] During the aforementioned vibration process, the target anchor 21 rises and falls vertically. Under the action of the limiting frame 35 and the latch 20, the latch 20 and the two chisel mesh plates 11 on both sides will rise and fall together. The two corresponding chisel mesh plates 11 will fold at a small angle due to the gap reserved between the workpieces. The chisel mesh plates 11 on both sides of the target anchor 21 will rise back towards the middle, and will not rise and fall vertically. At this time, the chisel end 30 is forced to vibrate along with the chisel mesh plate 11. This movement of the chisel end 30 makes it easier to widen the chisel point.

[0026] Other roughened mesh plates 11 on the same chain 16 are not prone to vibration due to gravity. Furthermore, the chain 16 is macroscopically a flexible connection, the connecting male head 31 and the connecting pin 32 have casting tolerances, the anchor hole formed by the irregular hole 27 is larger than the size of the limiting frame 35, the rotating shaft 38 allows the corresponding two locks 20 to fold, there are small gaps between any adjacent roughened mesh plates 11, and the edges of the roughened mesh plates 11 are all chamfered. Therefore, during the formal chiseling, the beam and slab are only locally stressed and will not be damaged. Moreover, the concentrated pressure makes it easier to roughen the surface. In addition, since the chiseling points are located in the initial chiseling stage, after the surface is roughened, a single-layer grid-like distribution of pits will be formed. The pits are evenly located and have similar size and depth.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
