Technical Field
[0001] This utility model relates to the field of bridge deck paving construction technology, specifically to a baseline control device for concrete bridge deck paving construction. Background Technology
[0002] Bridge deck paving is a crucial step in bridge construction. Its primary function is to protect the main beam from direct wear from vehicle tires and from rainwater erosion. Furthermore, it effectively distributes concentrated loads from vehicle wheels. Elevation control during concrete bridge deck paving construction is critical, directly impacting the paving thickness and consequently the height of the guardrails and subsequent surface layer construction. Traditional methods for elevation control in concrete bridge deck paving involve a simple device consisting of one horizontal and one vertical support rod, using the guardrail reinforcement as a support. This device is easily affected by wind speed and human factors, and the significant deflection of the guardrail reinforcement further hinders elevation control. Utility Model Content
[0003] To address the problems of the prior art, this utility model provides a control device for the baseline of concrete bridge deck paving construction. The device can be stabilized at the edge of the side beam by the clamping mechanism, reducing the influence of natural wind and other factors and improving the overall stability.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a control device for the baseline of concrete bridge deck paving construction, comprising a first support rod, a clamping base for clamping on the edge of the side beam at the lower end of the first support rod, a horizontal support rod fixedly connected to the upper part of the first support rod, a vertical fastening sleeve slidably connected to the horizontal support rod, a vertical support rod passing through the vertical fastening sleeve, a baseline positioning groove fixedly connected to the upper end of the vertical support rod, and a locking component for locking the vertical support rod on the vertical fastening sleeve.
[0005] The above structural design, which uses a clamping base directly fixed to the side beam, solves the problem of insufficient stability caused by the traditional device relying on the steel reinforcement of the guardrail for support; the sliding connection design of the horizontal and vertical support rods realizes multi-dimensional adjustment of the baseline position to adapt to the needs of different construction scenarios.
[0006] Preferably, the vertical fastening sleeve is fixedly connected to the horizontal fastening sleeve, the horizontal fastening sleeve is sleeved on the horizontal support rod, and a horizontal fastening bolt is vertically threaded through the sleeve wall of the horizontal fastening sleeve.
[0007] The above structural design, with the cooperation of the transverse fastening sleeve and the transverse support rod, enables fine adjustment of the transverse position, adapting to the construction of bridge decks of different widths; the transverse fastening bolts are locked by threads to ensure reliable fixation of the transverse position and prevent loosening during use.
[0008] Preferably, the transverse support rod is a U-shaped rod, the bent part of the transverse support rod is fixedly connected to the top end of the first support rod, and transverse fastening sleeves are fitted at both ends of the transverse support rod.
[0009] With the above structural design, transverse fastening sleeves can be installed at both ends, realizing dual-sided baseline control and improving construction efficiency; the fixed connection method of the bending part makes the force transmission more uniform and reduces local stress concentration.
[0010] Preferably, the locking assembly includes a vertical fastening bolt threaded through the wall of the vertical fastening sleeve, an anti-slip pad fixedly connected to the bottom end of the vertical fastening bolt, and the end face of the vertical fastening bolt abutting against the outer wall of the vertical support rod.
[0011] The above structural design, with vertical fastening bolts and anti-slip pads, increases friction and ensures the vertical support rod is securely locked. The threaded connection allows for stepless adjustment of the vertical height, meeting different elevation control requirements. The structure is simple, easy to operate, and facilitates quick adjustment and locking.
[0012] Preferably, the locking assembly includes a mounting shell fixedly connected to the outer wall of the vertical fastening sleeve, an eccentric wheel hinged to the rear end of the mounting shell, a retaining plate disposed inside the mounting shell, a baffle fixedly connected to the middle of the retaining plate, and a return spring disposed between the baffle and the outer wall of the vertical fastening sleeve. The retaining plate is vertically inserted through the wall of the vertical fastening sleeve, and multiple retaining grooves matching the retaining plate are formed along the length direction of the vertical support rod. The end of the retaining plate penetrates the shell wall of the mounting shell, and the end of the retaining plate abuts against the outer wall of the eccentric wheel. A handle is fixedly connected to the outer wall of the eccentric wheel.
[0013] The above structural design enables rapid locking and releasing, greatly improving operational efficiency; the combination of the slot and the plate ensures the accuracy and reliability of vertical height positioning; and the automatic reset design of the return spring makes operation more convenient and labor-saving.
[0014] Preferably, the clamping base includes a lower clamping plate fixedly connected to the bottom end of the first support rod, an upper clamping plate sleeved on the first support rod, and a base fastening sleeve threaded onto the first support rod. Base anti-slip pads are fixedly connected to the inner sidewalls of both the lower clamping plate and the upper clamping plate.
[0015] The above structural design, with upper and lower clamping plates and base fastening sleeve, enables reliable clamping of side beams of different thicknesses; the base anti-slip pad increases friction and prevents the device from sliding during construction; the threaded base fastening sleeve allows for precise adjustment of the clamping force, ensuring stability while avoiding damage to the side beams.
[0016] Compared with the prior art, the beneficial effects of this utility model are: This device uses a clamping base to directly clamp onto the edge of the side beam, replacing the traditional support method that relies on the guardrail steel bars. This fundamentally solves the problem of device swaying caused by the large deflection of the guardrail steel bars. Through the locking design of the horizontal fastening bolts and the vertical locking components (bolts or eccentric wheel structure), the position of each support rod is ensured to be fixed, improving the stability of elevation control. The sliding fit between the horizontal support rod and the horizontal fastening sleeve, and the adjustable connection between the vertical support rod and the vertical fastening sleeve, realize the flexible adjustment of the baseline position in three dimensions: horizontal, vertical, and longitudinal.

Detailed Implementation
[0018] Example 1: Please see Figure 1 This utility model provides a technical solution: a control device for the baseline of concrete bridge deck paving construction, including a first support rod 1, a clamping base 2 for clamping on the side beam at the lower end of the first support rod 1, a horizontal support rod 3 fixedly connected to the upper part of the first support rod 1, a vertical fastening sleeve 4 slidably connected to the horizontal support rod 3, a vertical support rod 5 passing through the vertical fastening sleeve 4, a baseline positioning groove 6 fixedly connected to the upper end of the vertical support rod 5, and a locking component for locking the vertical support rod 5 on the vertical fastening sleeve 4.
[0019] The baseline positioning groove 6 is made of thick stainless steel plate bent into a "U" shape with the opening facing upwards and the bottom of the groove rounded to avoid wear on the baseline. The slot is fixed to the top of the vertical support rod 5, and the upper surface of the baseline positioning groove 6 is fixedly connected to the level bubble 9. The level bubble 9 is used to monitor the horizontal status of the device in real time. If the position of the device changes, the position of the bubble in the level bubble 9 also changes accordingly.
[0020] The vertical fastening sleeve 4 is fixedly connected to the horizontal fastening sleeve 31. The vertical fastening sleeve 4 is vertically welded to the middle of the horizontal fastening sleeve 31. The horizontal fastening sleeve 31 is sleeved on the horizontal support rod 3. A horizontal fastening bolt 32 is threaded vertically through the sleeve wall of the horizontal fastening sleeve 31. To increase the friction between the horizontal fastening bolt 32 and the horizontal support rod 3, a rubber pad is fixedly connected to the end face of the horizontal fastening bolt 32. When the horizontal fastening bolt 32 is rotated, the end of the horizontal fastening bolt 32 abuts against the outer wall of the horizontal support rod 3, locking the horizontal position through friction.
[0021] The transverse support rod 3 is a U-shaped rod, which is made by bending a round tube into a U-shape. The bent part of the transverse support rod 3 is fixedly connected to the top of the first support rod 1. The bent part of the transverse support rod 3 is fixed to the top of the first support rod 1 by full welding to ensure the rigidity of the transverse support. Both ends of the transverse support rod 3 are fitted with transverse fastening sleeves 31. The transverse fastening sleeves 31 are fitted on the horizontal sections at both ends of the transverse support rod 3 and can slide along the horizontal sections at both ends of the transverse support rod 3. The vertical fastening sleeve 4 is fixedly connected between the two transverse fastening sleeves 31.
[0022] The locking assembly includes a vertically threaded bolt 41 that passes vertically through the wall of the vertical fastening sleeve 4, and an anti-slip pad fixedly connected to the bottom end of the vertical fastening bolt. The end face of the vertical fastening bolt 41 abuts against the outer wall of the vertical support rod 5, and the anti-slip pad contacts the outer wall of the vertical support rod 5. When the vertical fastening bolt 41 is tightened, the anti-slip pad is compressed, ensuring that the vertical support rod 5 does not slip.
[0023] The clamping base 2 includes a lower clamping plate 71 fixedly connected to the bottom end of the first support rod 1, an upper clamping plate 72 sleeved on the first support rod 1, and a base fastening sleeve 73 threadedly sleeved on the first support rod 1. Base anti-slip pads are fixedly connected to the inner walls of both the lower clamping plate 71 and the upper clamping plate 72. The base anti-slip pads are corrugated. Striped anti-slip rubber pads are fixedly connected to the outer wall of the base fastening sleeve 73, allowing workers to tighten the base fastening sleeve 73. Alternatively, a hexagonal drive head is fixedly connected to the outer wall of the base fastening sleeve 73 for tightening with a wrench. When the base fastening sleeve 73 is rotated, the upper clamping plate 72 is pushed downwards via threaded transmission, forming a clamping action against the side beam with the lower clamping plate 71.
[0024] Working principle: First, fix the clamping base, then place the lower clamping plate 71 horizontally against the lower surface of the side beam, slide the upper clamping plate 72 to the upper surface of the side beam, and rotate the base fastening sleeve 73 until the anti-slip pads of the upper clamping plate 72 and the lower clamping plate 71 are tightly fitted with the side beam to ensure that the entire device does not shake.
[0025] Next, adjust the lateral position by sliding the lateral fastening sleeve 31 along the horizontal sections of both ends of the lateral support rod 3 (U-shaped rod) to determine the lateral distance of the baseline. After aligning the position, tighten the lateral fastening bolt 32 with a wrench so that the bolt end is in close contact with the outer wall of the lateral support rod 3 to lock the lateral position.
[0026] Next, adjust and lock the vertical height, loosen the vertical fastening bolt 41, slide the vertical support rod 5 up and down, calibrate the height of the baseline positioning groove 6 to the construction elevation using a level, and then tighten the vertical fastening bolt 41 with a wrench to compress the anti-slip pad at the bottom of the bolt and make it fit tightly against the outer wall of the vertical support rod 5, thereby locking the vertical height.
[0027] Finally, the baseline is set up by placing the construction baseline into the baseline positioning groove 6, tensioning and temporarily fixing both ends to complete the baseline erection.
[0028] Example 2: Please see Figure 2 , Figure 3 Embodiment 2 differs from Embodiment 1 in that the locking assembly includes a mounting shell 61 fixedly connected to the outer wall of the vertical fastening sleeve 4, an eccentric wheel 62 hinged to the rear end of the mounting shell 61, a retaining plate 63 disposed inside the mounting shell 61, a baffle 64 fixedly connected to the middle of the retaining plate 63, and a return spring 65 disposed between the baffle 64 and the outer wall of the vertical fastening sleeve 4. The retaining plate 63 is vertically inserted through the cylinder wall of the vertical fastening sleeve 4, and multiple slots 66 matching the retaining plate 63 are opened along the length direction of the vertical support rod 5. The slots 66 are evenly spaced along the length direction of the vertical support rod 5, and the spacing of the slots 66 (controlled at 5-15mm) is small to ensure accuracy. The end of the retaining plate 63 penetrates the shell wall of the mounting shell 61, and the end of the retaining plate 63 abuts against the outer wall of the eccentric wheel 62. A handle is fixedly connected to the outer wall of the eccentric wheel 62.
[0029] Move the handle to the "unlocked position" (handle opens outwards). At this time, the return spring returns to its original length. The return spring pushes the locking plate 63 to disengage from the slot 66 of the vertical support rod 5, and the vertical support rod 5 slides up and down to the target elevation. Then move the handle to the "locked position" (handle tightens inwards). The locking plate 63 compresses the return spring 65, the eccentric wheel 62 rotates and pushes the locking plate 63 into the corresponding slot 66 to lock it in place.
[0030] Everything else is the same as in Example 1.
[0031] Working principle: First, fix the clamping base, then place the lower clamping plate 71 horizontally against the lower surface of the side beam, slide the upper clamping plate 72 to the upper surface of the side beam, and rotate the base fastening sleeve 73 until the anti-slip pads of the upper clamping plate 72 and the lower clamping plate 71 are tightly fitted with the side beam to ensure that the entire device does not shake.
[0032] Next, adjust the lateral position by sliding the lateral fastening sleeve 31 along the horizontal sections of both ends of the lateral support rod 3 (U-shaped rod) to determine the lateral distance of the baseline. After aligning the position, tighten the lateral fastening bolt 32 with a wrench so that the bolt end is in close contact with the outer wall of the lateral support rod 3 to lock the lateral position.
[0033] Next, adjust the vertical height and lock it. Move the handle to the "unlock position" (the handle opens outwards). At this time, the reset spring pushes the locking plate 63 to disengage from the slot 66 of the vertical support rod 5. Slide the vertical support rod 5 up and down to the target elevation. Then, move the handle to the "lock position" (the handle tightens inwards). The eccentric wheel 62 rotates and pushes the locking plate 63 into the corresponding slot 66 to lock it.
[0034] Finally, the baseline is set up by placing the construction baseline into the baseline positioning groove 6, tensioning and temporarily fixing both ends to complete the baseline erection.
