Description

Technical Field

[0001] This invention relates to the field of drainage ditch pouring equipment technology, specifically to a rapid formwork support device for drainage ditches. Background Technology

[0002] Drainage ditches are widely used in engineering and daily life. In engineering, they are longitudinal drainage ditches installed on both sides of roads to collect and drain rainwater from road surfaces, shoulders, and slopes. They are an integral part of road boundary surface drainage facilities, slope drainage systems, and an indispensable component of the overall drainage system. Drainage ditches act as a crucial link between the roadbed slope and the outer side of the road, serving as a vital "bridge" and playing a vital role in many aspects. By draining rainwater from the road surface and slopes, drainage ditches help maintain the stability of the roadbed.

[0003] The cross-section of drainage ditches is usually U-shaped. During construction, the base is first poured, and then the formwork is installed on the base to pour the two side walls. When installing the formwork, the commonly used technical solution is to drill holes in the base surface on the outside of the formwork, install external support rods or external support frames in the holes, and then drill holes in the formwork to install tie bolts. The purpose is to prevent the formwork from shifting or protruding. This construction method is both time-consuming and labor-intensive, with low construction efficiency and poor fixing effect on the drainage ditch formwork. During the subsequent concrete vibration process, the formwork is prone to displacement, affecting the construction quality of the drainage ditch. Summary of the Invention

[0004] To address the problems of the prior art, this invention provides a quick formwork clamp and formwork equipment for drainage ditches, which can quickly support and fix the formwork, and the construction method is simple, convenient, and efficient.

[0005] A quick formwork clamp for drainage ditches includes a horizontal bar and four vertical bars. The upper ends of the vertical bars are fixedly installed on the horizontal bar, and the vertical bars are arranged perpendicular to the horizontal bar. The four vertical bars are arranged in pairs, and each pair of vertical bars is used to support the outer side of the formwork.

[0006] Preferably, a support rod is installed between the two uprights mounted on the crossbar.

[0007] Preferably, the support rod is arranged parallel to the crossbar.

[0008] Preferably, the support rod is installed at the lower end of the upright.

[0009] Preferably, the length of the upright is greater than the height of the formwork.

[0010] The working principle and beneficial effects of the clamps are as follows: During the installation and construction of the drainage ditch formwork, the formwork is first placed in place. There are four formwork pieces in total, which serve as the templates for the two side walls of the drainage ditch. Then, the clamps are inserted from above and downwards into the formwork and clamped onto it. The adjacent clamps are spaced 50cm-80cm apart. The support rods and crossbars play a supporting and positioning role. After the clamps are installed, the concrete is poured. When the concrete reaches the demolding conditions, the clamps can be removed to carry out the demolding operation. This avoids the cumbersome procedures of drilling holes in the ground to set up support rods and drilling holes in the formwork to set up tie bolts when installing the formwork. The whole operation method is simple, convenient and efficient.

[0011] A rapid formwork support device for drainage ditches includes a mobile vehicle. A guide mechanism is installed at the lower end of the mobile vehicle, which is used to engage with the formwork and move along the length of the formwork. A placement slot for placing fixtures is provided on the mobile vehicle. A pushing mechanism is installed at the front end of the placement slot, which is used to push the fixtures towards the rear of the placement slot. A slot adapted to the contour of the fixtures is formed at the bottom of the rear end of the placement slot. A clamping mechanism is installed on the outside of the placement slot, which is used to clamp the side of the fixtures at the rearmost end of the placement slot. A pressing mechanism is installed above the slot, which is used to push the fixtures located above the slots downwards.

[0012] Preferably, the sidewall of the placement groove is a rectangular groove surrounded by a ring of plates. The pushing mechanism includes a motor, a screw, a guide rod, and a push plate. The screw and the guide rod are respectively installed on the outer sides of the two side walls of the placement groove. The rotating shaft of the motor is fixedly connected to one end of the screw. The push plate is placed in the placement groove to push the clamp to move backward. The two sides of the push plate extend out of the sidewall of the placement groove, and one side is threaded onto the screw, while the other side is slidably installed onto the guide rod.

[0013] Preferably, a support frame is installed at the rear of the mobile vehicle, and the clamping mechanism consists of two sets, symmetrically installed on the support frame. The clamping mechanism includes a mounting base, a top plate, and a spring. The mounting base is installed on the front side of the support frame, one end of the spring is connected to the mounting base, and the other end is connected to the top plate. The top plate is used to clamp the rear side of the clamp.

[0014] Preferably, the pressing mechanism includes a cylinder and a pressure plate. The cylinder is vertically mounted on the upright frame, and the pressure plate is mounted on the end of the telescopic shaft below the cylinder. The lower end face of the pressure plate is the working surface and its outline area is less than or equal to the upper end face of the clamp. The lower end face of the pressure plate is located directly above the slot.

[0015] Preferably, the mobile vehicle includes a chassis, four uprights and wheels. The uprights are installed at the four lower corners of the chassis, and the wheels are respectively installed at the lower ends of the uprights. The drainage groove is located on the chassis, and the placement groove and the upright are both installed on the chassis. The chassis is higher than the formwork height.

[0016] Preferably, a through groove is provided on the side wall of the trough, and the through groove is located directly below the cylinder.

[0017] Preferably, an opening is provided on the rear side wall of the placement slot.

[0018] Preferably, the guiding mechanism is an inverted U-shaped block, which is installed on the lower end surface of the chassis and is engaged with the formwork.

[0019] The application principle of the formwork support equipment of this invention is as follows: The worker first places the formwork on the base of the drainage ditch that has been poured. The moving vehicle is also placed on the base of the drainage ditch that has been poured. The guide mechanism is clamped on the already laid formwork for guidance and positioning. The clamps are placed in the placement slot and arranged neatly. The pushing mechanism and the tightening mechanism work synchronously to clamp the front and rear ends of a row of clamps. The pushing mechanism pushes the clamps to move, pushing the last clamp to the top of the trough. At this time, the tightening mechanism presses the clamps so that they will not fall out of the trough. The pressing mechanism is activated, pressing the clamps down and extending them out of the trough, where they are clamped on the formwork to fix the formwork in position.

[0020] The advantages of this invention include: placing the clamp in the placement slot, guiding the entire equipment to move along the formwork direction through the guiding mechanism, and automatically pressing the clamp onto the formwork through the coordinated cooperation of the pushing mechanism, the tightening mechanism and the pressing mechanism, without the need for manual operation, and installing the clamp while the equipment is moving, which is simple and efficient.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] A quick-setting formwork clamp for drainage ditches includes a horizontal bar 31 and four vertical bars 32. The upper ends of the vertical bars 32 are fixedly installed on the horizontal bar 31, and the vertical bars 32 are arranged perpendicularly to the horizontal bar 31. The four vertical bars 32 are arranged in pairs, and each pair of vertical bars 32 is used to support the outer side of the formwork 2. A support rod 33 is installed between the two vertical bars 32 installed on the horizontal bar 31, and the support rod 33 is arranged parallel to the horizontal bar 31.

[0034] The support rod 33 can be installed at any height between the two uprights 32. In this embodiment, the support rod 33 is installed at the lower end of the uprights 32. The purpose of this arrangement is that the support rod 33 can support the base 1, which can not only support and fix the formwork 2, but also stabilize the entire support structure.

[0035] The length of the upright 32 is greater than the height of the formwork 2, so that the lower ends of the support rod 33 and the upright 32 can reach the base 1, and the horizontal bar 31 is located above the formwork 2, which also facilitates installation and disassembly.

[0036] The working principle and beneficial effects of clamp 3 are as follows: When installing the drainage ditch formwork 2, the formwork 2 is first placed in place. There are four formwork 2 pieces in total, which serve as templates for the two side walls of the drainage ditch. Then, clamp 3 is inserted from above the formwork 2 and clamped onto the formwork 2. The adjacent clamps 3 are spaced 50cm-80cm apart. The support rod 33 and the crossbar 31 play a supporting and positioning role. After the clamp 3 is installed, the concrete is poured. When the concrete reaches the demolding condition, the clamp 3 can be removed to carry out the demolding operation. This avoids the cumbersome procedures of drilling holes in the ground to set up support rods 33 and drilling holes in the formwork to set up tie bolts when installing the formwork. The whole operation method is simple, convenient and efficient.

[0037] Example 2

[0038] A rapid formwork support device for drainage ditches includes a mobile vehicle 4. A guide mechanism is installed at the lower end of the mobile vehicle 4, which is used to engage with the formwork and move along the length of the formwork. A placement groove 5 for placing a clamp 3 is provided on the mobile vehicle 4. An opening is provided on the rear side wall of the placement groove 5. A pushing mechanism 8 is installed at the front end of the placement groove 5, which is used to push the clamp 3 towards the rear of the placement groove 5. A slot 7 adapted to the contour of the clamp 3 is opened at the bottom of the rear end of the placement groove 5. A clamping mechanism 10 is installed on the outside of the placement groove 5, which is used to clamp the side of the clamp 3 at the rearmost end of the placement groove 5. A pressing mechanism 11 is installed above the slot 7, which is used to push the clamp 3 located above the slot 7 downwards.

[0039] Furthermore, in this embodiment, the sidewall of the placement groove 5 is a rectangular groove surrounded by a ring of plates. The pushing mechanism 8 includes a motor 81, a screw 82, a guide rod 83, and a push plate 84. The screw 82 and the guide rod 83 are respectively installed on the outer sides of the two side walls of the placement groove 5. The rotating shaft of the motor 81 is fixedly connected to one end of the screw 82. The push plate 84 is placed in the placement groove 5 to push the clamp 3 to move backward. The two sides of the push plate 84 extend out of the sidewall of the placement groove 5, and one side is threaded onto the screw 82, while the other side is slidably installed onto the guide rod 83. The motor 81 starts, driving the screw 82 to rotate, which in turn drives the push plate 84 to move. The function of the smooth rod 83 is to balance the force on the push plate 84. The distance that the push plate 84 moves each time is the width of one clamp 3. That is, after one clamp 3 at the rear end of the placement slot 5 is pressed down and installed, the push plate 84 pushes a distance of one clamp 3 width, pushing the clamp 3 back above the slot 7.

[0040] Furthermore, in this embodiment, a support frame 9 is installed at the rear of the mobile vehicle 4. Two sets of clamping mechanisms 10 are symmetrically installed on the support frame 9. Each clamping mechanism 10 includes a mounting base 101, a top plate 102, and a spring 103. The mounting base 101 is installed on the front side of the support frame 9. One end of the spring 103 is connected to the mounting base 101, and the other end is connected to the top plate 102. The top plate 102 is used to clamp the rear side of the clamp 3. The clamping mechanism 10 uses the elastic force of the spring 103 to hold the clamp 3 above the slot 7 in place, preventing the clamp 3 from falling off automatically and causing inaccurate installation.

[0041] Furthermore, in this embodiment, the pressing mechanism 11 includes a cylinder 111 and a pressure plate 112. The cylinder 111 is vertically mounted on the support frame 9, and the pressure plate 112 is mounted on the end of the telescopic shaft below the cylinder 111. The lower end face of the pressure plate 112 is the working surface, and its outline area is less than or equal to the upper end face of the clamp 3. The lower end face of the pressure plate 112 is located directly above the slot 7. After the cylinder 111 is activated, the telescopic shaft extends downward, and the pressure plate 112 presses down on the clamp 3, overcoming the clamping force of the top plate 102 and moving downward. This provides stability for the clamp 3 during downward movement, enabling the clamp 3 to be accurately installed on the support 2 and preventing the clamp 3 from shifting or misaligning.

[0042] Furthermore, in this embodiment, the mobile vehicle 4 includes a chassis 41, four uprights 42, and wheels 43. The uprights 42 are installed at the four lower corners of the chassis 41, and the wheels 43 are respectively installed at the lower ends of the uprights 42. The trough 7 is located on the chassis 41, and the placement trough 5 and the support frame 9 are both installed on the chassis 41. The chassis 41 is higher than the height of the formwork 2.

[0043] A through groove 71 is provided on the side wall of the trough 7, and the through groove 71 is located directly below the cylinder 111; the through groove 71 is to prevent interference when the telescopic rod of the cylinder 111 moves down.

[0044] Furthermore, in this embodiment, the guiding mechanism is an inverted U-shaped block 12, which is installed on the lower end surface of the chassis 41 and is engaged with the support mold 2. The U-shaped block 12 is engaged with the upper end of the support mold 2, so that the entire device has a directional guiding effect when moving along the direction of the support mold 2, thereby enabling the clamp 3 to be accurately positioned by mechanical structure during installation.

[0045] The application principle of the formwork support device of the present invention is as follows: The worker first places the formwork on the base 1 of the drainage ditch that has been poured. The moving vehicle 4 is also placed on the base 1 of the drainage ditch that has been poured. The guide mechanism is clamped on the already laid formwork for guidance and positioning. The clamps 3 are placed in the placement groove 5 and arranged neatly. The pushing mechanism 8 and the tightening mechanism 10 work synchronously to clamp the front and rear ends of a row of clamps 3. The pushing mechanism 8 pushes the clamps 3 to move, pushing the last clamp 3 to the top of the trough 7. At this time, the tightening mechanism 10 presses the clamps 3 so that they will not fall from the trough 7. The pressing mechanism 11 is activated, pressing the clamps 3 down and extending them out of the trough 7, where they are clamped on the formwork to fix the formwork in position.
