Background Art

[0002] There are many ways to connect components in prefabricated buildings, among which sleeve connection is the most common connection method. The quality of the connection is related to the safety of the entire building, and it is the weak link of prefabricated buildings. In particular, the fullness of the grouting of the sleeve is crucial to the safety of prefabricated buildings. At present, the form of the sleeve is basically a slurry inlet pipe and an exhaust pipe. If the exhaust is not sufficient, it is easy for the grouting to be incomplete at the top of the sleeve. At present, various grouting measures have emerged, which can, to a certain extent, have a certain grouting effect on the incomplete sleeve. However, since the grouting uses the slurry outlet, it is difficult to discharge the gas and the grouting is difficult to be fully full. Summary of the Invention

The connecting exhaust pipe assembly is composed of at least two connecting exhaust pipe units. During the grouting operation, one of the connecting exhaust pipe units in the connecting exhaust pipe assembly is a grouting pipe, and the other connecting exhaust pipe units are exhaust pipes. The connecting exhaust pipe assembly is provided with a sleeve detection ruler and a grouting oscillation line connected to an external accessory. The sleeve can be a full grouting sleeve or a half grouting sleeve. The present invention can also be extended to a half grouting sleeve.

[0005] Preferably, the grouting inlet pipe is connected to the grouting equipment, and the angle between the central axis of the grouting inlet pipe and the horizontal plane is between 10° and 30°.

[0006] Preferably, when the communicating exhaust pipe assembly is composed of two communicating exhaust pipe units, namely a first communicating exhaust pipe and a second communicating exhaust pipe, the first communicating exhaust pipe and the second communicating exhaust pipe are arranged at the same horizontal height on the side of the grouting sleeve body.

[0007] Preferably, the first connecting exhaust pipe and the second connecting exhaust pipe are both arranged at an inclination relative to the horizontal plane, and the inclination angle between the first connecting exhaust pipe and the horizontal plane and between the second connecting exhaust pipe and the horizontal plane is 20°-40°.

[0008] Preferably, the first connecting exhaust pipe and the second connecting exhaust pipe are both cylindrical pipes, and the extension lines of the central axis of the first connecting exhaust pipe and the central axis of the second connecting exhaust pipe intersect or coincide with each other.

[0009] Preferably, the central axis of the first connecting exhaust pipe and the extended line of the central axis of the second connecting exhaust pipe form an acute angle when they intersect, and the acute angle is 45°-75°.

[0010] Preferably, the communicating exhaust pipe assembly is fixed integrally with the grouting sleeve body.

[0011] Preferably, the slurry reservoir is movably connected to the communicating exhaust pipe assembly, and the movably connection is: the communicating exhaust pipe assembly is provided with screws or bolts for riveting the slurry reservoir; the slurry reservoir is a transparent structure, the lower end of the slurry reservoir is connected to the communicating exhaust pipe assembly, and the upper end of the slurry reservoir is provided with a sealer connected to the slurry reservoir screws or bolts.

[0013] A grouting method for an assembled building grouting sleeve, using an assembled building grouting sleeve, comprising:

[0014] Step S1: Grouting operation: connect the grouting equipment to the grouting inlet pipe to perform grouting. The gas will be discharged along the connecting exhaust pipe assembly. The slurry gradually fills the grouting sleeve body. When the grouting sleeve body is full, the slurry enters the connecting exhaust pipe assembly. After the connecting exhaust pipe assembly is full, the slurry enters the slurry temporary reservoir. When a preset amount of slurry is stored in the slurry temporary reservoir, grouting is suspended, the grouting equipment is disconnected from the grouting inlet pipe, and the inlet of the grouting inlet pipe is blocked.

[0015] Step S2: Grouting operation. When the grouting equipment is pulled out to seal the inlet of the grouting pipe in time, the sleeve detection ruler in the connected exhaust pipe assembly is used to determine the fullness of the grouting on the top of the grouting sleeve body. When it is full, no grouting is required. When it is not full, grouting is required. When grouting, one of the connected exhaust pipe assemblies is a grouting pipe, and the remaining connected exhaust pipe units are exhaust pipes. The grouting equipment is connected to the grouting pipe, and grouting is started to allow the slurry to enter the grouting sleeve body. Grouting of the grouting sleeve body is started. When the slurry fills the grouting sleeve body, the slurry enters the connected exhaust pipe assembly. When the connected exhaust pipe assembly is full of slurry and the slurry flows out, grouting is stopped.

[0016] The advantages of the present invention are as follows: the grouting equipment grouts at the inlet of the grouting inlet pipe, and exhausts at the same time through the connected exhaust pipe assembly, so that the exhaust is more complete; when the grouting sleeve body is full of slurry, the slurry enters the connected exhaust pipe assembly, and then enters the slurry temporary reservoir. When the sleeve detection ruler in the connected exhaust pipe assembly detects that the grouting sleeve body is not full, grouting is performed, and the grouting sleeve body changes its function, one of which serves as a grouting pipe and the others still serve as exhaust pipes. At the same time, the grouting oscillation line oscillates, so that the exhaust is more thorough and the grouting is sufficient. The present invention utilizes the connected exhaust pipe assembly to fully exhaust, and when grouting, one of them can be slurryed and the others can be exhausted, so that the grouting is more complete and the grouting of the grouting sleeve body is ensured to be full.

DETAILED DESCRIPTION

[0023] The prefabricated building grouting sleeve of the present invention includes a vertically arranged grouting sleeve body 1, a grouting inlet pipe 2 arranged at the bottom of the side of the grouting sleeve body, a connecting exhaust pipe assembly 3 arranged at the top of the side of the grouting sleeve body, and a slurry temporary storage 4 connected to the connecting exhaust pipe assembly 3. The connecting exhaust pipe assembly 3 is composed of at least two connecting exhaust pipe units. During the grouting operation, one of the connecting exhaust pipe units in the connecting exhaust pipe assembly is a grouting pipe, and the other connecting exhaust pipe units are exhaust pipes. The connecting exhaust pipe assembly 3 is provided with a sleeve detection ruler 5 and a grouting oscillation line 6 connected to an external accessory. The grouting equipment grouts at the inlet of the grouting inlet pipe, and the connecting exhaust pipe assembly exhausts air at the same time to make the exhaust more complete. When the slurry fills the grouting sleeve body, the slurry enters the connecting exhaust pipe assembly and then enters the slurry temporary storage. When the sleeve detection ruler in the connected exhaust pipe assembly detects that the grouting sleeve body is not full, grouting is performed, and the grouting sleeve body changes its function, one of which serves as a grouting pipe and the rest still serves as exhaust pipes. At the same time, the grouting oscillation line oscillates to make the exhaust more thorough and the grouting fully completed. The present invention utilizes the connected exhaust pipe assembly to fully exhaust the air. During grouting, one of the pipes can be used to fill the grout while the rest are exhausted, making the grouting more complete and ensuring that the grouting sleeve body is fully filled.

[0024] The aforementioned grouting inlet pipe is connected to the grouting equipment, and the angle between the central axis of the grouting inlet pipe and the horizontal plane is between 10° and 30°, with 20° being the optimal angle. The above arrangement avoids the inevitable slurry backflow that occurs when the grouting inlet pipe is pulled out of the grouting equipment in a conventional horizontal arrangement, thereby providing a certain degree of resistance to slurry outflow. Under the same pressure, the amount of slurry flowing out of the grouting sleeve body is reduced compared to the grouting inlet of a conventional horizontal arrangement, ensuring a denser slurry inside the grouting sleeve body.

[0025] When the above-mentioned connecting exhaust pipe assembly 3 is composed of two connecting exhaust pipe units, namely the first connecting exhaust pipe 31 and the second connecting exhaust pipe 32, the first connecting exhaust pipe and the second connecting exhaust pipe are arranged at the same horizontal height on the side of the grouting sleeve body. The first connecting exhaust pipe 31 and the second connecting exhaust pipe 32 are both inclined relative to the horizontal plane, and the inclination angle between the first connecting exhaust pipe and the horizontal plane and between the second connecting exhaust pipe and the horizontal plane is 20°-40°, and the optimal angle is 30°. The first connecting exhaust pipe 31 and the second connecting exhaust pipe 32 are both cylindrical tubes. The central axis of the first connecting exhaust pipe and the extension of the central axis of the second connecting exhaust pipe intersect or coincide with each other. When the central axis of the first connecting exhaust pipe and the extension of the central axis of the second connecting exhaust pipe intersect, an acute angle is formed. The acute angle is 45°-75°, and the optimal angle is 60°. The two interconnecting exhaust pipe units are arranged on the same horizontal plane at a certain angle, such as 60° or 180°. The arrangement angle can be adjusted according to the different construction types and construction conditions of the prefabricated building. The interconnecting exhaust pipe units can be arranged on the same side of the component or on opposite sides of the component. The installation of two interconnecting exhaust pipe units can fully exhaust the grouting process, ensuring more complete grouting. The interconnecting exhaust pipe units are arranged at a certain elevation angle with the horizontal plane to ensure that the slurry flows back under the action of gravity.

[0026] The above-mentioned connecting exhaust pipe assembly 3 is cast or welded integrally with the grouting sleeve body 1, and the slurry reservoir 4 is movably connected to the connecting exhaust pipe assembly 3. The movably connected is as follows: the connecting exhaust pipe assembly 3 is provided with screws or bolts for riveting the slurry reservoir 4; the slurry reservoir 4 is a transparent structure, the lower end of the slurry reservoir 4 is connected to the connecting exhaust pipe assembly 3, and the upper end of the slurry reservoir 4 is provided with a sealer 7 connected to the slurry reservoir screws or bolts. The connecting exhaust pipe is cast together with the sleeve or welded together, and each exhaust pipe outlet portion has a screw, which enables the exhaust pipe to be connected to the slurry reservoir. The material of the slurry reservoir is transparent materials such as organic glass, so that the grouting position can be observed at any time; one end is connected to the connecting exhaust pipe assembly 3, and the other end has a closable opening, and the sealer is also connected with screws. In addition, the slurry reservoir can be reused.

[0027] The above-mentioned sleeve inspection ruler 5 is placed along the inner wall of the connecting exhaust pipe assembly. The sleeve inspection ruler 5 includes a base 51 and a rod 52 with a scale connected to the base. The base 51 is located on the side close to the grouting sleeve body 1. When the connecting exhaust pipe assembly 3 is composed of two connecting exhaust pipe units, the sleeve inspection ruler 5 is composed of a pair. The bottom of the sleeve inspection ruler is a base with a slightly larger horizontal area, and the top is a rod with a scale connected to the base. The angle between the sleeve inspection ruler and the base is the same as the angle between the connecting exhaust pipe assembly and the horizontal plane. During testing, a sleeve inspection ruler 5 is placed in each connecting exhaust pipe unit. Since the size of the connecting exhaust pipe unit is known, the sleeve inspection ruler 5 can be used to measure the final position of the slurry and determine the fullness of the top of the grouting sleeve body.

[0028] The grouting oscillation line 6 is a metal wire or non-metal wire structure, and is fixedly mounted on the communicating exhaust pipe assembly 3. During the grouting process, the grouting oscillation line 6 oscillates sufficiently to expel air. When not in use, the grouting oscillation line 6 is fixed to the side of the communicating exhaust pipe.

[0029] A grouting method for an assembled building grouting sleeve, comprising:

[0030] Step S1: Grouting operation: connect the grouting equipment to the grouting inlet pipe to perform grouting. The gas will be discharged along the connecting exhaust pipe assembly. The slurry gradually fills the grouting sleeve body. When the grouting sleeve body is full, the slurry enters the connecting exhaust pipe assembly. After the connecting exhaust pipe assembly is full, the slurry enters the slurry temporary reservoir. When a preset amount of slurry is stored in the slurry temporary reservoir, grouting is suspended, the grouting equipment is disconnected from the grouting inlet pipe, and the inlet of the grouting inlet pipe is blocked.

[0031] When a single grouting sleeve body is grouting, a slurry temporary reservoir may not be used; when multiple grouting sleeve bodies are used for grouting at the same time, the corresponding connecting exhaust pipe assemblies of the multiple grouting sleeve bodies are all equipped with slurry temporary reservoirs. The grouting sleeve body close to the grouting equipment is filled first, and then after the slurry fills the connecting exhaust pipe assembly, it enters the slurry temporary reservoir. The slurry temporary reservoir is stored to a preset height, and the corresponding slurry temporary reservoirs are closed in sequence from near to far. The grouting temporary reservoir farthest from the grouting equipment may not be closed. After entering the preset amount, grouting is stopped, the grouting equipment is pulled out, and the inlet of the grouting pipe is closed.

[0032] Step S2: Grouting operation. When the grouting equipment is pulled out to seal the inlet of the grouting pipe in time, the sleeve detection ruler in the connected exhaust pipe assembly is used to determine the fullness of the grouting on the top of the grouting sleeve body. When it is full, no grouting is required. When it is not full, grouting is required. When grouting, one of the connected exhaust pipe assemblies is a grouting pipe, and the remaining connected exhaust pipe units are exhaust pipes. The grouting equipment is connected to the grouting pipe, and grouting is started to allow the slurry to enter the grouting sleeve body. Grouting of the grouting sleeve body is started. When the slurry fills the grouting sleeve body, the slurry enters the connected exhaust pipe assembly. When the connected exhaust pipe assembly is full of slurry and the slurry flows out, grouting is stopped.
