Description

Technical Field

[0001] This invention relates to the field of concrete, and more specifically to an ultrathin concrete and its preparation process. Background Technology

[0002] Ultrathin concrete is a high-strength, tough, and durable engineering material with good applications in marine engineering, special security and protection engineering, and other fields. This type of ultrathin concrete has a small thickness, consumes less material, and has high toughness. However, its strength is still relatively weaker than that of very thick concrete, especially at bending points, where the strength is insufficient. Therefore, reinforcement is needed at these bending points. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides an ultrathin concrete and its preparation process, the beneficial effect of which is that it can prepare reinforced ultrathin concrete.

[0004] A process for preparing ultrathin concrete includes the following steps:

[0005] S1: Adjust the distance between the fixed angle plate and the moving angle plate on the preparation device, and set a gap between the fixed angle plate and the moving angle plate;

[0006] S2: Place the two limiting plates in front of and behind the fixed angle plate and the movable angle plate, respectively;

[0007] S3: Insert the three inserts between the two limiting plates so that the three inserts are located at the bends of the fixed angle plate and the moving angle plate;

[0008] S4: Pass multiple steel wires through the gap between the fixed angle plate and the movable angle plate, so that the multiple steel wires pass through three reinforcing bars;

[0009] S5: Pour concrete into the gap between the fixed angle plate and the movable angle plate;

[0010] S6: Wait for the concrete to harden, then separate the fixed angle plate and the movable angle plate and remove the concrete.

[0011] Both the fixed angle plate and the movable angle plate are arc-shaped.

[0012] The fixed angle plate and the movable angle plate are made of stainless steel.

[0013] The material of the insert is steel. Attached Figure Description

[0030] A process for preparing ultrathin concrete includes the following steps:

[0031] S1: Adjust the distance between the fixed angle plate 101 and the movable angle plate 201 on the preparation device, and set a gap between the fixed angle plate 101 and the movable angle plate 201;

[0032] S2: Place the two limiting plates 301 on the front and rear sides of the fixed angle plate 101 and the movable angle plate 201, respectively;

[0033] S3: Insert three insert ribs 302 between two limiting plates 301, so that the three insert ribs 302 are located at the curved part of the fixed angle plate 101 and the movable angle plate 201;

[0034] S4: Pass multiple steel wires through the gap between the fixed angle plate 101 and the movable angle plate 201, so that the multiple steel wires pass through the three reinforcing bars 302;

[0035] S5: Pour concrete into the gap between the fixed angle plate 101 and the movable angle plate 201;

[0036] S6: Wait for the concrete to harden, then separate the fixed angle plate 101 and the movable angle plate 201 and remove the concrete.

[0037] Both the fixed angle plate 101 and the movable angle plate 201 are arc-shaped.

[0038] The fixed angle plate 101 and the movable angle plate 201 are made of stainless steel.

[0039] The material of the reinforcing bar 302 is steel.

[0040] like Figure 6-7 As shown, this example can achieve the effect of forming an ultra-thin concrete with a curved shape.

[0041] Since the preparation device includes a fixed angle plate 101, a base plate 103 is welded to the lower side of the fixed angle plate 101, a baffle 102 is welded to the right side of the fixed angle plate 101, and a movable angle plate 201 is set on the upper side of the fixed angle plate 101, with both ends of the movable angle plate 201 in contact with the base plate 103 and the baffle 102 respectively, a gap is formed between the fixed angle plate 101 and the movable angle plate 201, the baffle 102 blocks the right side of the gap, and the base plate 103 blocks the lower side of the gap, concrete can be poured into the gap to form a curved ultra-thin concrete.

[0042] like Figure 6-7 As shown, this example can achieve the effect of pouring concrete into the gap through the feed channel 202.

[0043] Since the upper right side of the movable angle plate 201 is connected to the feed channel 202 by screws, concrete can be poured into the gap through the feed channel 202.

[0044] like Figure 6-7As shown, this example demonstrates how the movable corner plate 201 can be removed from the concrete once it has hardened.

[0045] Because an L-shaped column 203 is slidably connected to the base plate 103 in the left and right directions, and the L-shaped column 203 is driven by a hydraulic cylinder, a boss 204 is connected to the left side of the movable angle plate 201 by screws. The boss 204 is vertically slidably connected to the L-shaped column 203 and fixed to the L-shaped column 203 by screws. The hydraulic cylinder can drive the L-shaped column 203 to slide left and right, thereby driving the movable angle plate 201 to move left and right, adjusting the left and right distance between the movable angle plate 201 and the fixed angle plate 101. The movable angle plate 201 can slide vertically on the L-shaped column 203 through the boss 204, thereby adjusting the vertical distance between the movable angle plate 201 and the fixed angle plate 101. When the concrete solidifies, the movable angle plate 201 can be removed from the concrete.

[0046] like Figure 6-7 As shown, this example demonstrates how ultrathin concrete can be used for overall reinforcement.

[0047] Because the base plate 103 has multiple bottom holes 108 arranged from front to back, and the baffle 102 has multiple side holes 109 arranged from front to back, multiple steel wires can be inserted into the concrete through the multiple bottom holes 108, and then the multiple steel wires can be inserted out through the multiple side holes 109, and then the multiple steel wires can be placed in the concrete from front to back, thus embedding the multiple steel wires in the concrete, thereby strengthening the ultra-thin concrete as a whole.

[0048] like Figure 8-10 As shown, this example demonstrates how three 302 reinforcing bars can reinforce the corners of ultra-thin concrete.

[0049] Since there are two limiting plates 301, which block the front and rear sides of the fixed angle plate 101 and the moving angle plate 201 respectively, and three reinforcing bars 302 are provided, each of which is inserted into the two limiting plates 301 at its front and rear ends respectively. The reinforcing bars 302 are provided with strip grooves 303 and multiple positioning holes 304 from front to back. The two limiting plates 301 can block the front and rear sides of the gap, thereby preventing concrete from leaking out from the front and rear sides of the gap. Three reinforcing bars 302 are inserted in the front and rear direction at the bend of the ultra-thin concrete. The three reinforcing bars 302 reinforce the bend of the ultra-thin concrete, and multiple steel wires pass through the three reinforcing bars 302. The strip grooves 303 on the reinforcing bars 302 facilitate the passage of steel wires, and the multiple positioning holes 304 facilitate the positioning of steel wires and prevent the steel wires from moving back and forth relative to the reinforcing bars 302.

[0050] like Figure 2-11 As shown, this example demonstrates how the reinforcement effect is enhanced by the intersection of three 302 reinforcing bars and multiple steel wires.

[0051] The ultrathin concrete prepared by a certain ultrathin concrete preparation process is arc-shaped, with three reinforcing bars 302 embedded at the arc corners. Multiple steel wires are embedded in the ultrathin concrete, passing through the three reinforcing bars 302. The three reinforcing bars 302 reinforce the corners, and the multiple steel wires reinforce the entire ultrathin concrete. The intersection of the three reinforcing bars 302 and the multiple steel wires enhances the reinforcement effect.

[0052] A connecting seat 405 is welded onto the fixed angle plate 101. A rotating shaft 407 in the front-to-back direction is connected to the connecting seat 405 by screws. An axial ridge 406 is provided on the rotating shaft 407. Slide cylinders 305 are integrally formed on both limiting plates 301. The two slide cylinders 305 are slidably connected to the two ends of the rotating shaft 407 respectively. Telescopic rods 404 are connected to the front and rear sides of the connecting seat 405 by screws. The movable ends of the two telescopic rods 404 are respectively connected to the two limiting plates 301.

[0053] like Figure 8-11 As shown, this example allows for the convenient opening and closing of the two limit plates 301.

[0054] When the two telescopic rods 404 are in motion, they drive the two sliding cylinders 305 to slide on the rotating shaft 407, thereby driving the two limiting plates 301 to move back and forth, so as to facilitate opening and closing the two limiting plates 301.

[0055] A fixing seat 306 is connected to the limiting plate 301 by screws. A sliding column 307 is slidably connected to the fixing seat 306. An arc 308 is welded to the end of the sliding column 307. The arc 308 presses against the ends of multiple inserts 302. The sliding column 307 is pressed and fixed to the arc 308 by screws.

[0056] like Figure 8-10 As shown, this example can prevent multiple reinforcing bars 302 from moving back and forth arbitrarily.

[0057] The sliding column 307 can slide on the fixed seat 306, thereby driving the pressing arc 308 to move. When the pressing arc 308 moves, it can press on the ends of multiple inserts 302, thereby fixing the multiple inserts 302 on the limiting plate 301 and preventing the multiple inserts 302 from moving back and forth at will.

[0058] A pressure strip 104 is slidably connected to the lower side of the base plate 103 in the left-right direction. The pressure strip 104 is driven to slide by a hydraulic cylinder. The right side of the pressure strip 104 is an arc-shaped surface. Multiple insertion holes 106 are provided on the drum 105 from front to back. The drum 105 is rotatably connected to the right side of the baffle 102 through a bearing seat. The drum 105 is driven to rotate by a motor 107.

[0059] like Figure 6-7As shown, this example demonstrates how to tighten the steel wires inside ultrathin concrete.

[0060] Since the pressure strip 104 can move left and right, the driving pressure strip 104 can press against the steel wires at the multiple bottom holes 108, thereby fixing the lower ends of the multiple steel wires at the multiple bottom holes 108. After the upper ends of the multiple steel wires pass through the multiple side holes 109, they can be inserted into the multiple insertion holes 106 on the drum 105. Then the motor 107 drives the drum 105 to rotate, and the rotation of the drum 105 winds up the multiple steel wires, thereby tightening the steel wires inside the ultra-thin concrete.

[0061] The rear part of the rotating shaft 407 is fitted into the upper part of the bracket 401 with a clearance fit. Two circular pieces 403 are welded to the rear part of the bracket 401. The two circular pieces 403 are located on both sides of the bracket 401. Two compression springs are sleeved on the rotating shaft 407. The outer ends of the two compression springs are in contact with the two circular pieces 403 respectively. The rear end of the rotating shaft 407 is connected to the handle 402 by screws.

[0062] like Figure 11 As shown, this example can achieve the effect of making concrete dense.

[0063] The rotating shaft 407 can move back and forth and rotate on the bracket 401, thereby driving the concrete in the gap between the fixed angle plate 101 and the moving angle plate 201 to shake, thereby shaking the concrete in the gap evenly and making the concrete dense. The upper side of the bracket 401 is provided with screws, which can be used to fix the rotating shaft 407 on the bracket 401. The movement of the rotating shaft 407 can be easily controlled by the handle 402.
