Description

Technical Field

[0001] The present application relates to the field of concrete pouring, and in particular to a concrete anti-falling device for pouring a super-high column with a joint device. Background Art

[0002] On a construction site, when concrete is poured in sections, special templates need to be set up at the construction joints. These templates usually have waterproof and anti-leakage functions, and can also ensure reliable mechanical engagement between the newly poured concrete and the hardened concrete. At the same time, before and after pouring, the construction joints need to be cleaned and processed, such as using a roughening machine to roughen the surface of the old concrete to increase the roughness and facilitate the bonding of the new and old concrete.

[0003] When concrete falls freely from a height, due to the effect of gravity, the coarse aggregate and cement paste inside will separate, which is called segregation. Segregation will lead to uneven internal structure of concrete, reducing the overall quality and durability of concrete. Therefore, when the concrete is poured at a height of more than 2 to 3 meters, an anti-fall device is needed to prevent concrete from segregating. At the same time, due to the high height of concrete pouring, especially when pouring concrete on super-high columns, uncontrolled concrete falling may cause danger to the construction site and pose a threat to the workers below. The anti-fall device can avoid the impact damage caused by the sudden fall of concrete and ensure construction safety.

[0004] The conical string barrel is a relatively common anti-falling device. By adjusting the inclination angle and outlet size of the conical string barrel, the outflow speed of concrete can be effectively controlled to match the receiving capacity of the casting surface. At the same time, its smooth inner wall can significantly reduce the friction between the concrete and the inner wall of the string barrel, reduce the possibility of concrete adhering to the inner wall during the flow process, and reduce concrete loss. At the same time, a guide plate is often set in the conical string barrel to guide the concrete to flow along a specific path in the string barrel. The common guide plate is set to a plane type. The plane structure has limited buffering effect on the impact force of concrete, which may increase the flow resistance of concrete, thereby affecting the casting efficiency and casting quality. In order to solve the above problems, a concrete anti-falling device for casting super-high columns with a joint device is proposed.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-5 This application is described in further detail.

[0024] The embodiment of the present application discloses a concrete anti-fall device for casting a super-high column with a joint device. Figure 1-5 , a concrete anti-fall device for casting a super-high column with a joint device, comprising an anti-fall string tube 1, in which a conical guide plate 8 for guiding the concrete in the anti-fall string tube 1 and a telescopic component 9 for connecting and supporting the conical guide plate 8 are arranged;

[0025] It should be noted that the anti-fall string tube 1 is set to be a cone with a larger top and a smaller bottom;

[0026] By adopting the above technical solution, when concrete enters the anti-fall string tube 1 from the feeding equipment, it falls along the inner wall of the anti-fall string tube 1. Under the action of the gravity of the concrete, the telescopic component 9 extends, so that the conical guide plate 8 can effectively guide the concrete to gradually accelerate or decelerate along the wall surface of the conical guide plate 8. The conical shape of the conical guide plate 8 helps to disperse the pressure, avoid strong impact and splashing when the fluid suddenly changes direction, and reduce the impact force on the joint template.

[0027] Reference Figure 2 , the bottom of the conical guide plate 8 is hollow;

[0028] By adopting the above technical solution, the bottom of the conical guide plate 8 is hollow, which can reduce the stagnation and accumulation of concrete during the flow process and avoid the formation of blockage points at the bottom of the conical guide plate 8.

[0029] Reference Figure 4 The telescopic assembly 9 includes a telescopic rod 91 and a return spring 92. The return spring 92 is sleeved on the telescopic rod 91. The two ends of the telescopic rod 91 are respectively fixedly connected to the anti-fall string tube 1 and the conical guide plate 8;

[0030] By adopting the above technical solution, the concrete rushes toward the conical guide plate 8, and under the action of gravity, the telescopic rod 91 is extended, and the reset spring 92 is also extended, so that the concrete can flow evenly along the conical surface of the conical guide plate 8 to the conical inner wall of the next layer of the anti-fall string tube 1.

[0031] Reference Figure 2 , 3 5. A chute 11 is provided at the bottom of the anti-fall string tube 1, and the telescopic rod 91 is fixed in the chute 11;

[0032] It should be noted that the chute 11 is opened along the conical surface of the anti-fall string tube 1. Due to the angle limitation of the conical surface, even under the action of the concrete gravity, the telescopic rod 91 will not be infinitely extended, so that the diversion angle between the conical guide plate 8 and the anti-fall string tube 1 can be optimal, thereby ensuring the diversion effect of the conical guide plate 8;

[0033] By adopting the above technical solution, the setting of the bottom slide groove 11 of the anti-fall string tube 1 can fix and limit the telescopic rod 91, thereby ensuring the diversion effect of the conical guide plate 8.

[0034] Reference Figure 1 , 2 The anti-fall string tube 1 includes a connecting tube 101 and a guide tube 102, a fixing flange 2 is fixed on the connecting tube 101, and the guide tube 102 is threadedly connected with the connecting ring 24;

[0035] It should be noted that the connecting cylinder 101 is connected and fixed to the concrete feeding equipment through the fixing flange 2, and the guide cylinder 102 is connected step by step below the connecting cylinder 101;

[0036] By adopting the above technical solution, the connecting ring 2 4 is threadedly connected to the guide tube 102, so that the guide tubes 102 can be connected in sequence, thereby avoiding leakage of slurry from the connection of the guide tube 102 during concrete pouring.

[0037] Reference Figure 1-3 The outside of the connecting tube 101 and the guide tube 102 are fixedly provided with a connecting ring 1 3 and a connecting ring 2 4, a hoop plate 5 is fixedly provided between the connecting ring 1 3 and the connecting ring 2 4, a fastening bolt 6 is threadedly provided on the hoop plate 5, and a support member 7 is also circumferentially provided between the connecting ring 1 3 and the connecting ring 2 4;

[0038] It should be noted that the support member 7 is a support rod, and the two ends of the support member 7 are respectively welded and fixed to the connecting ring 1 3 and the connecting ring 2 4;

[0039] It should be further explained that the hoop plate 5 is formed into a ring around the middle part of the connecting ring 1 3 and the connecting ring 2 4, and forms a hoop by cooperating with the fastening bolts 6;

[0040] By adopting the above technical solution, the connecting ring 1 3 and the connecting ring 2 4 can be fixed to the outer lower side of the connecting tube 101 and the guide tube 102 by welding, and the hoop plate 5 can further support the connecting ring 1 3 and the connecting ring 2 4 by tightening the fastening bolts 6. The connecting ring 1 3 and the connecting ring 2 4 can serve as external supporting structures to increase the lateral stiffness of the connecting tube 101 and the guide tube 102 to prevent lateral bending or twisting deformation caused by internal pressure or external collision during concrete pouring. The support member 7 can maintain the stability of the connecting tube 101 and the guide tube 102.

[0041] Reference Figure 2 , a conical spiral joint 10 is provided at the bottom of the connecting ring 2 4;

[0042] By adopting the above technical solution, the connecting ring 2 4 is threadedly connected to the guide tube 102 through the conical spiral joint 10, and the inclination angle of the conical spiral joint 10 can match the inner wall of the guide tube 102, thereby not affecting the falling of concrete.

[0043] The implementation principle of the concrete anti-fall device for casting super-high columns by the joint device of the embodiment of the present application is as follows: when in use, the hoop plate 5 is fixed between the connecting ring 1 3 and the connecting ring 2 in sequence by the fastening bolts 6, and then the connecting tube 101 is connected and fixed to the concrete feeding equipment through the fixing flange 2, and then the guide tube 102 is threadedly fixed through the connecting ring 2 4 in sequence according to the required length. After the connection is completed, concrete casting is carried out. When the concrete enters the connecting tube 101 from the feeding equipment, it falls along the inner wall of the connecting tube 101, and the concrete rushes to the conical guide plate 8. Under the action of gravity, the telescopic rod 91 is extended, and the reset spring 92 is also extended together, so that the concrete can flow evenly along the conical surface of the conical guide plate 8 to the conical inner wall of the guide tube 102. The conical shape of the conical guide plate 8 helps to disperse the pressure, avoid strong impact and splashing when the fluid suddenly changes direction, and can reduce the impact force on the joint template, thereby improving the quality of concrete casting.
