Description

Technical Field

[0001] The invention relates to the technical field of assembled prefabricated components, in particular to a steel bar connecting device for assembled prefabricated components. Background Art

[0002] In recent years, the country has proposed the future development direction of the construction industry, namely smart cities, green buildings and building industrialization. Vigorously developing prefabricated buildings is the only way to improve the industrialization of traditional construction methods. The technical level of prefabricated buildings is a direct reflection of the country's construction capabilities and scientific and technological strength. Comprehensively promoting the development of prefabricated buildings has become a top priority for the construction industry. In the construction of prefabricated buildings, the steel bar connection performance of prefabricated prefabricated components is a key factor in the force transmission of steel bars, which plays a decisive role in the effect of steel bar force transmission and the integrity of the structure. The choice of steel bar connection method directly affects the construction speed and structural quality of the building.

[0003] The existing Chinese patent with publication number CN213509229U discloses an assembled wall reinforcement connection device. When it is necessary to pour concrete in the mold 8, the lower opening of the grouting sleeve is aligned with the reserved circular hole in the mold, and the bolt head 6 is driven by an electric wrench to rotate, so that the screw plug 4 is tightened at the lower end of the grouting sleeve, and concrete is poured in the mold 8 to form an upper wall. When it is necessary to assemble the upper wall and the lower wall, the bolt head 6 is driven by an electric wrench to rotate, so that the screw plug 4 is removed, the mold is taken out, and the lower wall reinforcement is extended into the lower chamber 2 through the lower end opening of the grouting sleeve, and grouting is performed into the lower chamber 2 through the grouting hole 21. When the grouting material flows out of the grouting hole 22, the grouting is completed. After the grouting material solidifies, the grouting pipe and the grouting pipe exposed outside the wall are cut off to complete the connection between the upper wall and the lower wall.

[0004] When the device is filled with cement, due to the connection between some parts inside the device, it is easy to cause the cement grouting to be loose, and the density of the slurry after grouting cannot be guaranteed. At the same time, the sleeve grouting connection method requires high precision. If the position of the steel bar deviates slightly, the on-site steel bar will be difficult to penetrate into the sleeve, which may easily cause unnecessary safety hazards.

[0005] Therefore, a steel bar connection device for assembled prefabricated components is needed to solve this problem. Summary of the invention

[0006] In order to solve all or part of the above-mentioned problems, the purpose of the present invention is to provide a steel bar connection device for assembled prefabricated components, so as to solve the problem proposed in the above-mentioned comparative document technology that when the device is filled with cement, due to the connection between some parts inside the device, it is easy to cause the cement grouting to be loose, and the density of the slurry after grouting cannot be guaranteed. At the same time, the sleeve grouting connection method has high precision requirements. If the position of the steel bar deviates slightly, it will be difficult for the on-site steel bar to penetrate into the sleeve, which may easily cause unnecessary safety hazards.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a steel bar connection device for assembled prefabricated components, comprising a sleeve, a steel bar 1 is installed through the upper end of the sleeve, a steel bar 2 is installed through the lower end of the sleeve, a grouting port is installed on the outer side of the sleeve, a slurry outlet is installed on the outer side of the sleeve, a vibrating rod is arranged on the inner side of the slurry outlet, the sleeve comprises a grouting outer shell, a grouting inner shell is fixedly installed on the inner side of the grouting outer shell, a plurality of holes 1 are opened on the grouting inner shell, and a circular grouting inner shell is fixedly installed between the grouting outer shell and the grouting inner shell. The round tube passes through the grouting inner shell and is fixedly connected with it. The end of the round tube away from the grouting inner shell is fixedly connected with the grouting outer shell. The round tube is distributed in stages on the grouting inner shell. A plurality of holes five are provided on the round tube. When we put the steel bar two and the steel bar one into the sleeve for grouting, we start the vibrating rod to vibrate the sleeve to reduce the bubbles of the grouting material in the sleeve. The grouting material enters the grouting inner shell through the grouting port. When the grouting material begins to fill the inside of the grouting inner shell under the action of pressure, the grouting material falls to the lower end of the grouting inner shell. The grouting material flows into the space between the grouting outer shell and the grouting inner shell through hole one, reducing the situation that the grouting outer shell is not filled when the grouting inner shell is filled under the action of pressure. At the same time, when the grouting material passes through hole one, the grouting material falling through the upper grouting port hits the grouting material already injected into the grouting inner shell through the action of gravity, and discharges a small amount of air inside. When the grouting material submerges the round tube, the grouting material is discharged between the grouting outer shell and the grouting inner shell through hole five. The slurry hits the grouting material between the grouting outer shell and the grouting inner shell to expel the internal air. When the grouting material submerges all the round tubes, the holes in the round tubes continue to be discharged. By squeezing the grouting material on the outside, the bubbles inside are expelled to make it more compact. When the grouting inner shell and the part between the grouting outer shell and the grouting inner shell are all filled, the overflowing grouting material is discharged through the slurry outlet. At the same time, we close the input of the grouting material and pull out the vibrating rod to seal the grouting port and the slurry outlet to complete the connection between steel bar one and steel bar two.

[0008] Furthermore, a fixed connecting rod is installed between the grouting outer shell and the grouting inner shell, the fixed connecting rod is located between the steel bar one and the steel bar two, and the fixed connecting rod is fixedly connected to both the grouting outer shell and the grouting inner shell. The grouting outer shell and the grouting inner shell are reinforced by the fixed connecting rod to prevent the grouting inner shell from being separated from the grouting inner shell under high-pressure grouting, and also to fix the casting of the steel bar one and the steel bar two.

[0009] Furthermore, multiple sets of fixed ring assemblies are fixedly installed on the inner side of the grouting inner shell, and the positions of the fixed ring assemblies correspond to steel bar 1. When we insert steel bar 1 and steel bar 2 into the sleeve, steel bar 1 is first stabilized by the fixed ring assembly, and then steel bar 2 is inserted into the sleeve.

[0010] Furthermore, a second hole is provided at the upper end of the grouting outer shell, a hole groove is provided at the lower end of the grouting outer shell, a gap is reserved between the grouting outer shell and the grouting inner shell, a round tube is arranged between the gap, and a steel bar 1 is positioned through the second hole so that the steel bar 1 is reinforced by the fixed circular ring assembly, and the grouting material is retained between the grouting outer shell and the grouting inner shell through the gap.

[0011] Furthermore, the fixed ring assembly includes a connecting block 1, a fixed ring 2 is fixedly installed on the end of the connecting block 1 away from the grouting inner shell, a bonding sheet is fixedly installed on the inner side of the fixed ring 2, the fixed ring 2 matches the steel bar 1, and after the position of the steel bar 1 is determined by the hole 2, it is fixed by the fixed ring 2, and the steel bar 1 is bonded to prevent slipping by the bonding sheet.

[0012] Furthermore, a connecting plate is slidably installed in the hole groove, an elastic part is fixedly installed on the outer side of the connecting plate, and the other end of the elastic part is fixedly connected to the grouting shell. After we determine and fix the position of steel bar 1 through hole 2, the position of steel bar 2 may not be matched due to inaccurate manual measurement, so we slide the connecting plate in the hole groove to position steel bar 2 through the connecting plate, and the connecting plate remains relatively stable through the action of each group of elastic parts.

[0013] Furthermore, a hole three is opened at the upper end of the connecting plate, and a fixing ring is fixedly installed at the upper end of the hole three. The hole three matches the size of the fixing ring, and the fixing ring matches the steel bar two. The steel bar two passes through the connecting plate through the hole three, and its position is fixed by the fixing ring. The position of the two groups of steel bars is matched, and pouring begins.

[0014] Furthermore, a plurality of holes four are provided on the grouting inner shell, and the holes four are distributed in stages, and the holes four match the circular tubes. The hole one is located at the lower end of the holes four, and the grouting material in the grouting inner shell is discharged into the circular tube through the holes four on the grouting inner shell, and the grouting material is discharged into the gap through the holes five on the circular tube. Through the circular tubes distributed in stages, the grouting material hits the grouting material at the lower end of the gap under the action of gravity, so that the air inside it is discharged.

[0015] Furthermore, a connecting rod is fixedly installed on the upper side of one end of the fixed connecting rod close to the slurry outlet, and a fixed ring is fixedly installed on the upper end of the connecting rod. The fixed ring matches the vibrating rod, and the end of the vibrating rod close to the fixed connecting rod is slidably connected to the grouting inner shell. The vibrating rod penetrates into the fixed ring to transmit the vibration into the interior of the sleeve, thereby shaking out the bubbles in the grouting inner shell.

[0016] Furthermore, a fixed ring three is fixedly installed inside the slurry outlet, a connecting block two is fixedly installed outside the fixed ring three, the other end of the connecting block two is fixedly connected to the outer shell of the slurry outlet, the fixed ring three matches the vibrating rod, and the diameter of the slurry outlet is larger than the diameter of the vibrating rod. The vibrating rod transmits the vibration to the grouting outer shell through the fixed ring three, discharges the gas in the grouting material in the gap, and enhances its compactness.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention proposes a steel bar connection device for assembled prefabricated components. When we put steel bar 2 and steel bar 1 into the sleeve for grouting, we start the vibrating rod to vibrate the sleeve to reduce the bubbles of the grouting material in the sleeve. The grouting material enters the interior of the grouting inner shell through the grouting port. When the grouting material begins to fill the interior of the grouting inner shell under the action of pressure, the grouting material falls to the lower end of the grouting inner shell, and a part of the grouting material flows into the space between the grouting outer shell and the grouting inner shell through the hole 1, thereby reducing the situation that the grouting outer shell is not filled when the grouting inner shell is full under the action of pressure. At the same time, when the grouting material passes through the hole 1, the grouting material falling through the upper end grouting port is used to press the grouting material already injected into the grouting inner shell through the action of gravity. The grouting material is tapped to expel a small amount of air inside. When the grouting material covers the circular tube, the grouting material is discharged through hole five to between the grouting outer shell and the grouting inner shell. The grouting material falling from the vibrating and stepped circular tubes taps the grouting material between the grouting outer shell and the grouting inner shell to expel the internal air. When the grouting material covers all the circular tubes, the holes in the circular tubes continue to discharge. By squeezing the grouting material on the outside, the bubbles inside are expelled to make it more compact. When the grouting inner shell and the part between the grouting outer shell and the grouting inner shell are filled, the overflowed grouting material is discharged through the slurry outlet. At the same time, we close the input of the grouting material and pull out the vibrating rod to seal the grouting port and the slurry outlet to complete the connection between steel bar one and steel bar two.
