Description

Technical Field

[0001] This application relates to the field of building construction equipment technology, and in particular to a concrete pouring equipment for building construction projects. Background Technology

[0002] In building construction, concrete pouring is a crucial step in the construction of the main structure, and its construction quality directly affects the overall strength, durability, and safety of the building.

[0003] Regarding the aforementioned technologies, the applicant believes that the current pouring equipment is equipped with a distribution pipe at the end, through which the concrete slurry is discharged. During this process, due to the excessively fast flow rate and large impact force of the concrete slurry, it is usually necessary to manually hold it to control the pouring point when it is discharged to the cast steel reinforcement skeleton, and splashing is prone to occur. Therefore, there is still room for improvement. Summary of the Invention

[0004] In order to solve the technical problem that the placing pipe of current concrete pouring equipment requires manual labor to control the pouring point and reduce splashing, this application provides a concrete pouring equipment for building construction.

[0005] The concrete pouring equipment for building construction provided in this application adopts the following technical solution: A concrete pouring device for building construction includes a pouring pipe connected to a concrete tank truck and a placing pipe installed on the pouring pipe. The placing pipe is provided with a buffer structure, which includes an arc-shaped column installed inside the placing pipe. The arc-shaped column includes a vertical guide part and an arc-shaped guide part. The arc-shaped guide part is located outside the vertical guide part, and the arc-shaped column is rotatably connected to the inner wall of the placing pipe.

[0006] By adopting the above technical solution, the arc-shaped column acts as a buffer during the falling process of the concrete slurry in the placing pipe, reducing the splashing that can easily occur when the concrete slurry is discharged to the cast steel reinforcement skeleton due to its high flow rate and large impact force. Furthermore, the gentle falling of the concrete slurry makes it easier to control the pouring position and requires less manual labor.

[0007] Preferably, the inner wall of the fabric tube is fixed with a support ring frame by a spaced connecting rod, and an annular plate passing through the support ring frame is fixed on the side wall of the arc-shaped column. Several ball bearings are installed at intervals inside the support ring frame and on the outer periphery of the annular plate.

[0008] By adopting the above technical solution, the ball bearings on the support ring frame change the rotation of the annular plate relative to the support ring frame into rolling friction, effectively reducing the friction coefficient. This allows the arc-shaped column to rotate as the concrete slurry falls, forming a horizontal shear force, which helps to reduce the flow velocity.

[0009] Preferably, through holes are provided at intervals on the sidewall of the arc-shaped guide section.

[0010] By adopting the above technical solution, through holes are set to reduce the possibility of concrete slurry deposition caused by the arc-shaped guide section.

[0011] Preferably, the buffer structure further includes a rectifier grille located on the upper part of the arc-shaped column; the rectifier grille is provided with intersecting grille bars, and the grille bars are cylindrical.

[0012] By adopting the above technical solution, the rectifier grid can cut the falling concrete slurry, interfere with the vertical fall of the concrete slurry, and achieve a deceleration effect, thereby preventing splashing and reducing the impact force of the falling concrete slurry.

[0013] Preferably, a sealing cover plate, which is closed outside the annular plate, is fixed on the outer wall of the support ring frame and located on the arc-shaped guide portion; and an inclined portion extending inclinedly toward the outer periphery of the support ring frame is fixed on the sealing cover plate.

[0014] By adopting the above technical solution, the ball bearings and the annular plate are sealed inside the support ring frame by the sealing cover plate, which prevents concrete slurry from entering and affecting the service life of the ball bearings, and ensures that the process of the ball bearings assisting the rotation of the arc column is not disturbed; the inclined part guides the concrete slurry to fall down, preventing it from accumulating on the support ring frame.

[0015] Preferably, the top of the vertical guide section is provided with a tapered constriction section.

[0016] By adopting the above technical solution, the top of the vertical guide section is set to be conical, which can reduce viscous resistance and reduce the overall rotational resistance of the arc-shaped column.

[0017] Preferably, the annular plate has a groove on its circumferential sidewall for accommodating the balls; and a reinforcing rod is fixed between adjacent connecting rods.

[0018] By adopting the above technical solution, the structural strength of the reinforcing rod is enhanced.

[0019] Preferably, the material distribution pipe is installed on the casting pipe via an installation structure.

[0020] By adopting the above technical solution, the installation structure enables the detachable connection of the placing pipe to the pouring pipe, which facilitates the installation and cleaning of the arc column. At the same time, the placing pipe can be replaced if the arc column inside the placing pipe is damaged.

[0021] Preferably, the installation structure includes an extension ring extending from the material distribution pipe and a fixing bolt for fixing the extension ring. The casting pipe is inserted into the extension ring, and a sealing ring is fixed on the inner side wall of the extension ring, with the sealing ring tightly attached to the outer side wall of the casting pipe. The fixing bolt is threadedly connected to the extension ring, the sealing ring, and the outer side wall of the casting pipe, and a gasket is installed on the fixing bolt to abut against the outer side wall of the extension ring.

[0022] Preferably, deformable limiting plates are fixed at intervals on the sealing ring, and limiting grooves are provided on the outer wall of the casting pipe for accommodating the corresponding limiting plates.

[0023] By adopting the above technical solution, the combination of the limiting plate and the limiting groove plays the role of relatively positioning the pouring pipe and the placing pipe, which makes it easy to insert the fixing bolts at the corresponding positions of the pouring pipe and the placing pipe to complete the relative fixation of the two.

[0024] In summary, this application includes at least one of the following beneficial technical effects: The curved column acts as a buffer during the descent of the concrete slurry in the placing pipe, reducing the risk of splashing when the concrete slurry reaches the cast steel reinforcement cage due to its high flow rate and impact force. The gentle descent of the concrete slurry also makes it easier to control the pouring point with less manual labor. The ball bearings on the support ring frame transform the rotation of the annular plate relative to the support ring frame into rolling friction, effectively reducing the coefficient of friction. This allows the arc-shaped column to rotate as the concrete slurry falls, generating horizontal shear force and helping to reduce the flow velocity. Through holes are provided to reduce concrete slurry deposition that may occur due to the arc-shaped guide section. The flow-rectifying grid can cut the falling concrete slurry, interfering with its vertical descent and slowing it down. This helps prevent splashing and reduce the impact force of the concrete slurry, making it easier for workers to control the pouring site. The installation structure enables a detachable connection between the placing pipe and the pouring pipe, facilitating the installation and cleaning of the curved column. It also allows for the replacement of the placing pipe if the curved column inside is damaged. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a concrete pouring device for building construction, referring to... Figure 1 It includes a pouring pipe 1 connected to a concrete mixer truck and a placing pipe 2 installed on the pouring pipe 1 via an installation structure 3.

[0029] Reference Figure 1 , 2 The material distribution pipe 2 is equipped with a buffer structure 4, which includes an arc-shaped column 42 installed inside the material distribution pipe 2. The installation structure 3 enables the detachable connection of the material distribution pipe 2 to the pouring pipe 1, thereby facilitating the installation and cleaning of the arc-shaped column 42. At the same time, the material distribution pipe 2 can be replaced if the arc-shaped column 42 inside the material distribution pipe 2 is damaged. It should be noted that an electric vibration motor can be installed outside the material distribution pipe 2 to assist the material discharge in the form of vibration.

[0030] Reference Figure 1 , 3 The installation structure 3 includes an extension ring 31 fixed above the material distribution pipe 2 and extending upward. The pouring pipe 1 is inserted into the extension ring 31, and a sealing ring 311 is fixed on the inner side wall of the extension ring 31. The sealing ring 311 is tightly attached to the outer side wall of the pouring pipe 1. Deformable limiting plates 5 are fixed at intervals on the sealing ring 311. A limiting groove 11 is provided on the outer side wall of the pouring pipe 1 for the corresponding limiting plate 5 to be accommodated. The cooperation of the limiting plate 5 and the limiting groove 11 can relatively position the pouring pipe 1 and the material distribution pipe 2. It should be noted that the sealing ring 311 can be easily replaced if it ages.

[0031] Reference Figure 1 , 3 The installation structure 3 also includes a fixing bolt 32 for fixing the extension ring 31. When the limiting plate 5 and the limiting groove 11 are positioned accordingly, the pouring pipe 1 and the material distribution pipe 2 do not rotate relative to each other. The fixing bolt 32 is threadedly connected to the corresponding positions of the extension ring 31, the sealing ring 311 and the outer side wall of the pouring pipe 1, and a gasket that abuts against the outer side wall of the extension ring 31 is installed on the fixing bolt 32.

[0032] Reference Figure 2 The buffer structure 4 also includes a flow-rectifying grid 41 located on the upper part of the arc-shaped column 42. The flow-rectifying grid 41 has intersecting grid bars 411, and the grid bars 411 are cylindrical to reduce the retention of concrete slurry. The flow-rectifying grid 41 can cut the falling concrete slurry, interfere with the vertical fall of the water flow, and play a deceleration role, so as to prevent splashing and reduce the impact force of the concrete slurry. At the same time, it also reduces the force of the concrete slurry directly impacting the arc-shaped column 42 and extends the service life of the structure.

[0033] Reference Figure 2 , 4 The arc-shaped column 42 includes a vertical guide section 421 and an arc-shaped guide section 422. The arc-shaped guide section 422 is located outside the vertical guide section 421, and the arc-shaped column 42 is rotatably connected to the inner wall of the placing pipe 2. The arc-shaped column 42 plays a buffering role in the falling process of the concrete slurry in the placing pipe 2, reducing the splashing situation that is easy to occur when the concrete slurry is discharged to the cast steel skeleton due to the large impact force caused by the excessive flow rate of the concrete slurry. Moreover, the slow falling of the concrete slurry makes it easier to control the pouring position and saves labor.

[0034] Reference Figure 2 The top of the vertical guide section 421 is provided with a conical contraction section 6; the top of the vertical guide section 421 is set as conical, which can reduce viscous resistance and reduce the overall rotational resistance of the arc-shaped column 42.

[0035] Reference Figure 2 , 4 Through holes 13 are provided at intervals on the side wall of the arc-shaped guide section 422; the through holes 13 are provided to reduce the possible deposition of concrete slurry due to the setting of the arc-shaped guide section 422.

[0036] Reference Figure 2 , 4 The inner wall of the fabric tube 2 is fixed with a support ring frame 7 by spaced connecting rods 21, and a reinforcing rod 211 is fixed between adjacent connecting rods 21 to enhance the structural strength of the connecting rods 21.

[0037] Reference Figure 2 , 4An annular plate 8, which passes through the support ring frame 7, is fixed on the side wall of the arc-shaped column 42. Several balls 9 are installed at intervals on the outer periphery of the annular plate 8 within the support ring frame 7. The balls 9 are ceramic balls with low friction. The balls 9 are supported by a vertical rod and rotate circumferentially around the vertical rod. The circumferential side wall of the annular plate 8 has a groove 81 for accommodating the balls 9. The balls 9 make the rotation of the annular plate 8 relative to the support ring frame 7 a rolling friction. The use of ceramic balls 9 effectively reduces frictional resistance, allowing the arc-shaped column 42 to rotate as the concrete slurry falls, forming a horizontal shear force. This helps to reduce the flow velocity, thereby achieving the purpose of splash prevention and reducing the impact force of the concrete slurry. It also makes it easier for workers to control the pouring point.

[0038] Reference Figure 2 , 4 A sealing cover plate 10, which is closed outside the annular plate 8, is fixed on the outer wall of the support ring frame 7 and located on the outer side of the arc-shaped guide portion 422. An inclined portion 12 extending towards the outer periphery of the support ring frame 7 is fixed on the sealing cover plate 10. The sealing cover plate 10 seals the ball bearing 9 and the annular plate 8 inside the support ring frame 7, preventing concrete slurry from entering and affecting the service life of the ball bearing 9, and ensuring that the process of the ball bearing 9 assisting the rotation of the arc-shaped column 42 is not disturbed. The inclined portion 12 guides the concrete slurry to fall, preventing it from accumulating on the support ring frame 7. It should be noted that the sealing cover plate 10 can be made of polyurethane material with high wear resistance, which can effectively resist the scraping of concrete slurry and is also easy to replace.

[0039] The working process of this application is as follows: Concrete slurry enters the placing pipe 2 from the pouring pipe 1. First, the straightening grid 41 cuts the falling concrete slurry to achieve initial buffering. Then, the concrete slurry continues to fall, diverts and passes through the through holes 13 on the vertical guide part 421 and the arc guide part 422. At the same time, the impact force of the concrete slurry causes the arc guide part 422 to rotate, forming a horizontal shear force, which plays an auxiliary role in slowing down. Finally, it achieves the functions of splash prevention and reducing the impact force of the concrete slurry, making it easier for workers to control the pouring position.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
