Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a prefabricated building insulation board exterior wall concrete pouring device. Background Technology

[0002] The concrete pouring for the exterior walls of prefabricated building insulation panels includes pouring concrete on both the inner and outer sides of the insulation panels. The outer side typically uses finer self-compacting concrete with aggregates less than 2cm in diameter to ensure a denser pour and prevent leakage of the insulation mesh. The inner side can use slightly coarser aggregates. The conventional process for pouring concrete for the exterior walls of prefabricated building insulation panels involves pouring the inner and outer sides separately. This method is prone to displacement of the insulation panels due to concrete impact, requiring repeated adjustments. Furthermore, manual sieving of aggregates is necessary during both inner and outer pours to ensure the outer side uses fine aggregates. This process is labor-intensive, has a long construction period, and low efficiency. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a prefabricated building insulation board exterior wall concrete pouring device.

[0004] This invention is achieved through the following technical solution: A prefabricated building insulation board exterior wall concrete pouring device includes a downward-sloping chute with supporting legs. The chute comprises symmetrically arranged short chutes on both sides and a long chute in the middle. Both the short and long chutes are equipped with baffles. Front support blocks are welded to the front ends of the baffles on both sides of the long chute, and rear support blocks are welded to the rear ends of the long chute. Fixing plates are symmetrically welded to the front and rear support blocks. Both the front and rear fixing plates have circular holes through which a fixing shaft passes. Fixing nuts are provided at both ends of the fixing shaft. The device also includes a screening box located above the chute, which is rectangular in shape and has an upward-convex arc bottom surface. The bottom surface of the screening box is equipped with an arc-shaped screen, and the density of the arc-shaped screen corresponding to the long chute is greater than that of the arc-shaped screen corresponding to the short chute. Connecting plates are welded to both the front and rear surfaces of the screening box. The connecting plates are rotatably connected to the fixed shaft. A short shaft is welded to the upper part of the connecting plate on the front surface. A sleeve A is rotatably connected to the short shaft. A connecting rod is fixed on the sleeve A. A sleeve B is provided at the other end of the connecting rod. A short rod is rotatably connected inside the sleeve B. The short rod is vertically connected to the rotating rod. A fixed sleeve is provided at the end of the rotating rod. The fixed sleeve is fixed to the motor shaft of the motor. The motor is mounted on the upper surface of the bracket through a motor base. The bracket is welded to the outer wall of the outer baffle of the short chute.

[0005] Preferably, the arc-shaped screen is composed of transverse steel bars and longitudinal steel bars.

[0006] The bottom of the bracket is welded with a stiffening plate, which is welded to the outer wall of the baffle on the outer side of the short chute.

[0007] Preferably, handles are provided on both the left and right sides of the chute.

[0008] Preferably, both the short shaft and the short rod are provided with fastening nuts.

[0009] The device of this invention can simultaneously pour concrete on the inner and outer sides of the insulation board exterior wall, avoiding the impact displacement problem of single-sided pouring on the insulation board. At the same time, an automatic screening device is set up, which enables simultaneous pouring of fine aggregate on the outer side of the insulation board while pouring concrete, reducing the labor intensity of workers and greatly improving construction efficiency.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0013] This embodiment includes a downward-sloping chute with an inclination angle selectable between 30-45°. Support legs 1 are provided downwards to support the entire chute. The chute comprises two symmetrically arranged short chutes 2 and a central long chute 3. The long chute 3 extends downwards in a greater length than the short chutes 2. The short chutes 2 on both sides are used for pouring the insulation board onto the inner side, while the long chute 3 is used for pouring the insulation board onto the outer side. Both the short chutes 2 and the long chute 3 are equipped with baffles 4, which create three independent chambers. To facilitate movement of the entire device, handles 27 are preferably provided on both sides of the chute, allowing the device to be moved.

[0014] Front support blocks 5 are welded to the front ends of the baffles 4 on both sides of the long chute 3. The two ends of the front support blocks 5 are welded to the baffles 4 on both sides of the long chute 3 respectively. Rear support blocks 6 are welded to the rear end of the long chute 3. Fixing plates 7 are symmetrically welded to the front support blocks 5 and the rear support blocks 6. The fixing plates 7 are provided with round holes 8. A fixing shaft 9 passes through the round holes 8. Fixing nuts 10 are provided at both ends of the fixing shaft 9. Tightening the fixing nuts 10 connects the fixing shaft 9 to the fixing plates 7.

[0015] A screening box 11 is provided above the chute, and the screening box 11 is used to put self-compacting concrete. The screening box 11 is rectangular in shape, and the bottom surface of the screening box 11 is an upward convex arc surface. The bottom surface of the screening box 11 is provided with an arc-shaped screen 12. Since the long chute 3 is used to pour the outer side of the insulation board, it requires aggregate with a smaller particle size, generally not exceeding 2cm. The short chute 2 is used to pour the inner side of the insulation board, and it can use coarser aggregate. Therefore, the density of the arc-shaped screen 12 corresponding to the long chute 3 is greater than the density of the arc-shaped screen 12 corresponding to the short chute 2. In this embodiment, the arc-shaped screen 12 is composed of transverse steel bars 24 and longitudinal steel bars 25. The transverse steel bars 24 are arc-shaped steel bars that are consistent with the arc shape of the bottom surface of the screening box 11. The longitudinal steel bars 25 are perpendicular to the transverse steel bars 24. The spacing of the longitudinal steel bars 25 above the long chute 3 is set to be no more than 2cm, while the spacing of the longitudinal steel bars 25 above the two short chute 2 sides is greater than 2cm, which is set according to the requirements. Connecting plates 13 are welded to both the front and rear faces of the screening box 11. The connecting plates 13 are fitted onto the fixed shaft 9 and can rotate around the fixed shaft 9.

[0016] This invention incorporates an automatic screening structure. Specifically, a short shaft 14 is welded to the upper part of the connecting plate 13 on the front end face of the screening box 11. A sleeve A15 is rotatably connected to the short shaft 14, and a connecting rod 16 is fixed to the sleeve A15. A sleeve B17 is fixed to the other end of the connecting rod 16. A short rod 18 is rotatably connected inside the sleeve B17. The short rod 18 is integrally connected to a rotating rod 19, which is perpendicular to the short rod 18. A fixing sleeve 20 is provided at the end of the rotating rod 19, and the fixing sleeve 20 is fixed to the motor shaft of the motor 21. The rotation of the motor shaft of motor 21 drives the rotating rod 19 to rotate as well. The rotation of the rotating rod 19 causes the connecting rod 16 to move left and right, thereby pulling the screening box 11 to rotate around the fixed shaft 9. The entire structure is similar to a crank-connecting rod mechanism, realizing the automatic left and right rotation of the screening box 11. During the shaking process, the fine aggregate in the self-compacting concrete in the screening box 11 can fall from the middle into the long chute 3, ensuring that the middle long chute 3 is filled with fine aggregate, while the coarse aggregate and fine aggregate fall together into the short chute 2 on both sides. Because the device may be subject to vibration and other interference factors during operation, in order to prevent the sleeve A15 from slipping off the short shaft 14 and the sleeve B17 from slipping off the short rod 18, it is preferable that both the short shaft 14 and the short rod 18 are equipped with fastening nuts 28. The motor 21 is mounted on the upper surface of the bracket 23 through the motor base 22. The bracket 23 is welded to the outer wall of the baffle 4 on the outer side of the short chute 2. A stiffening plate 26 is welded to the bottom of the bracket 23 to ensure the stability of the bracket 23. The stiffening plate 26 is welded to the outer wall of the outer baffle 4 of the short chute 2.

[0017] During construction, the device is placed on the top plate, with the long chute 3 aligned with the outer side of the insulation board and the short chute 2 aligned with the inner side of the insulation board. Self-compacting concrete is fed into the screening box 11. Then, the motor 21 is turned on, and the screening box 11 rotates back and forth slightly. Because the arc-shaped screen 12 at the bottom of the screening box 11 has a convex arc surface, during the left and right rotation, the self-compacting concrete with smaller aggregate particle size falls from the middle of the arc-shaped screen 12 into the long chute 3 and is poured onto the outer side of the insulation board, ensuring the compactness of the outer side of the insulation board. The shaking of the screening box 11 also prevents material from accumulating and clogging inside the screening box 11, realizing automatic feeding and screening, and greatly improving construction efficiency.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
