Description

Technical Field

[0001] This utility model relates to the field of composite board texturing technology, specifically a composite board texturing device. Background Technology

[0002] Composite floor slabs consist of precast composite slabs and cast-in-place concrete. Since the concrete is cast-in-place on the composite slab, to increase the contact area between the cast-in-place concrete and the composite slab and to increase the strength of the bond, a roughening device is used during the fabrication of the composite slab to create sawtooth-like grooves on its surface. This increases the contact area with the cast-in-place concrete. Existing roughening devices have multiple cutters. However, because these devices rely on the weight of the cutters themselves to penetrate the concrete, the cutters may not be able to effectively penetrate the concrete when encountering resistance, thus failing to guarantee the depth of the grooves and affecting the subsequent bonding quality between the composite slab and the cast-in-place concrete. Utility Model Content

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-4As shown, a composite board texturing device includes a horizontal shaft 1, with support parts at both ends of the horizontal shaft 1. Each support part includes a support frame 2, and the horizontal shaft 1 is rotatably connected to the support frame 2. Two wheels 3 are mounted on the support frame 2, and the horizontal shaft 1 is located above and between the two wheels 3. A mounting frame 4 is provided on one side of the horizontal shaft 1, and a rotating shaft 5 is mounted on the mounting frame 4. The device also includes a pull rod 6, one end of which is rotatably connected to the rotating shaft 5, and the other end of which is provided with two handles 7. Furthermore, the device includes a horizontal plate 8, with a plurality of texturing units evenly distributed on the lower surface of the horizontal plate 8. Each texturing unit includes a column 9, the upper end of which is fixedly connected to the horizontal plate 8, and the lower end of which passes through the horizontal shaft 1 and extends below the horizontal shaft 1. The lower end of the column 9 is provided with... The device includes a fixing block 10, a puller 11, a fixing shaft 12 on the puller 11, the fixing shaft 12 being rotatably connected to the fixing block 10, and upright plates 13 fixedly connected to both ends of the fixing shaft 12. A through hole is provided on the column 9 below the horizontal axis 1. The device also includes an elastic element 14 located inside the through hole. Both ends of the elastic element 14 are fixedly connected to the upright plates 13 on both sides of the column 9. The elastic element 14 is always in a stretched state. A screw 15 is threadedly connected to the horizontal axis 1. A handle 16 is provided at the lower end of the screw 15. The outer surface of the upper end of the screw 15 is smooth. The upper end of the screw 15 is rotatably connected to the horizontal plate 8. Limiting blocks 17 are provided on the screw 15 and on both sides of the horizontal plate 8.

[0018] When manufacturing the composite slab 22, a mold 21 is required. The steel reinforcement cage is installed into the mold 21, and concrete is poured into the mold 21. Once the concrete and the steel reinforcement cage are completely bonded together, the composite slab 22 is manufactured. After the concrete is poured into the mold 21, it is necessary to use a vibrating device to vibrate the concrete in the mold 21 to expel air from the concrete and improve the processing quality of the composite slab 22. After the concrete has been vibrated, a roughening device is used to roughen the upper surface of the uncured concrete.

[0019] Before roughening the concrete, the roughening depth needs to be adjusted. Specifically, the screw 15 is rotated by the handle 16. When the screw 15 rotates on the horizontal shaft 1, the screw 15 body can move up or down. Since the screw 15 and the horizontal plate 8 are rotatably connected, and the horizontal plate 8 is located between the two limit blocks 17, when the upper end of the screw 15 moves upward, it will push the horizontal plate 8 to move upward, thereby driving the lower cutter 11 to move upward. When the lower end of the screw 15 moves downward, it will drive the horizontal plate 8 to move downward, thereby driving the lower cutter 11 to move downward. The more the cutter 11 moves upward, the shallower the depth of the cutter 11 into the concrete.

[0020] After adjusting the height of the broach 11, the broaching device is moved to one side of the mold 21 via the wheel 3 and the pull rod 6, positioning the mold 21 between the two support frames 2. Then, the horizontal shaft 1 is moved by the handle 7 and the pull rod 6. Alternatively, the horizontal shaft 1 can be pulled by the handle 7 and the pull rod 6, as long as the broach 11 completely passes through the mold 21. During the movement of the broach 11, it will first contact one side of the mold 21. As the broach 11 is continuously pulled, it will rotate. When the elastic element 14 is stretched further, and after the pull cutter 11 passes one side of the mold 21, the stretched elastic element has the potential energy to restore its original length. Therefore, it will drive the pull cutter 11 to rotate through the vertical plate 13 and the fixed shaft 12, so that the lower end of the pull cutter 11 is vertically downward. During the process of returning to its original position, the pull cutter 11 will enter the interior of the concrete and make a groove on the upper layer of the concrete. When the pull cutter 11 contacts the other side of the mold 21, the pull cutter 11 can also rotate, so that the pull cutter 11 can be removed from the mold 21.

[0021] The elastic element 14 is an elastic rope. When the pull cutter 11 moves inside the mold 21, the elastic rope can stably move the pull cutter 11 in the concrete. When the pull cutter 11 moves in the concrete, it will be subject to the resistance applied to the pull cutter 11 by the concrete. However, under the action of this resistance, the rotation angle of the pull cutter 11 is still less than 20°, so as to ensure that the pull cutter 11 can effectively achieve the roughening effect.

[0022] Furthermore, after the initial roughening, the roughening device can be immediately pulled in the opposite direction to perform a secondary roughening of the concrete inside the mold 21, thereby improving the roughening effect.

[0023] Furthermore, the handles 7 are telescopic. When both handles 7 are fully extended, the distance between the outermost ends of the two handles 7 is greater than the width of the composite plate 22. When it is necessary to roughen the concrete in multiple molds 21 and the interval between two adjacent molds 21 is also small, the telescopic handles 7 can be extended. Two workers can control one of the handles 7 respectively and push or pull the roughening device on both sides of the mold 21 to move it, thereby realizing the roughening operation of the concrete in multiple molds 21 with close intervals.

[0024] Furthermore, a reinforcing sleeve 18 is provided on the upper surface of the horizontal shaft 1, and the screw 15 is threadedly connected to the reinforcing sleeve 18 to improve the stability of the fit between the screw 15 and the horizontal shaft 1.

[0025] Furthermore, a guide cylinder 19 is provided on the outer surface of the horizontal shaft 1. The guide cylinder 19 is slidably connected to the column 9 to improve the stability of the fit between the column 9 and the horizontal shaft 1.

[0026] Furthermore, the pull rod 6 is a hollow tube, and a pull ring 20 is provided at one end of the pull rod 6 to reduce the weight of the pull rod 6 and facilitate the operation of the pull rod 6. At the same time, it can be connected to an external engineering vehicle through the pull ring 20, so that the engineering vehicle can drive the roughening device to move, thereby improving the roughening efficiency.
