When the connecting piece is used, the sealing paper is torn off, the connecting piece is tightly adhered to the wall surface, and meanwhile, the transparent communicating pipe is upwards. After the slurry is solidified, the observer is removed from the position of the double-sided adhesive tape, and grouting work is finished, and the smoothness of the wall surface can be well kept.

In order to empty the air in the sleeve, a ventilation positioning pipe 4 is arranged, the ventilation positioning pipe 4 is a thin-wall metal pipe of a U-shaped structure, one end of the ventilation positioning pipe 4 is fixed between the connecting piece and the double-faced adhesive tape and is of an integral structure with the transparent communicating pipe, the other end of the ventilation positioning pipe extends into the top end of the sleeve, and the air at the top end of the sleeve is emptied in the grouting process.

Considering that concrete slurry has certain viscosity, in order to ensure smooth circulation of the slurry in the transparent communication pipe 2, the transparent communication pipe 2 is of a bent structure, and an angle of 60 degrees is formed between the transparent communication pipe 2 and the connecting piece 1, and the specific structural form is shown in fig. 1.

In order to ensure the grouting plumpness inside the sleeve, the upper end pipe orifice of the transparent communicating pipe 2 is higher than the height of the inner space of the sleeve. According to the principle of the communicating vessel, a scale mark is marked on the outer side of the transparent communicating pipe 2, and after the observer is installed, the height of the scale mark is consistent with that of the top end of the inner space of the sleeve. When slurry flows into the transparent communicating pipe from the sleeve slurry outlet 7, the liquid level continuously rises, when the position of the scale mark is reached, the sleeve in the assembled building component is considered to be full in grouting, and at the moment, the rotating sealing cover seals the observer, so that the slurry is prevented from flowing out to cause waste. The use state is shown in fig. 2.

In order to save energy, protect environment and save cost, the sleeve grouting fullness observer of the embodiment can be designed into a detachable structure to realize recycling.

Preferably, the transparent communication tube 2 is designed as a transparent plastic round tube with an inner diameter of 18mm and an outer diameter of 20 mm. In order to smoothly circulate the slurry in the transparent communication pipe, the transparent communication pipe 2 is designed to be a bent structure, the bending angle between the lower end part and the upper end part is 120 degrees, and the lower end part and the connecting piece 1 form an angle of 60 degrees. The integral structure of the sleeve grouting fullness observer with a bent structure is shown in fig. 3.

The sleeve grouting fullness observer of this embodiment utilizes the communicating vessel principle, and transparent communicating pipe 2 and the inside grout space of sleeve communicate, and the height of transparent communicating pipe 2 is higher than the inside space of sleeve. When the sleeve is grouted, the slurry can flow into the upper end part from the inclined pipe at the lower end part after reaching the slurry outlet 7 until reaching the top end of the transparent communicating pipe 2, and the sealing plate 3-2 prevents the slurry from flowing out. Because transparent communicating pipe 2 highly is higher than sleeve inner space height, according to the communicating vessel principle, through observing the height of transparent communicating pipe 2 interior concrete thick liquids, can learn whether sleeve inner space is filled fully in the milk, think sleeve inner space grout when the thick liquids fill in transparent communicating pipe 2 and accomplish the plumpness height.

After the slurry has set, the scope is broken off from the groove and removed, as shown in fig. 6. The construction site can be kept clean, and the wall surface flatness can be well kept.

The transparent communicating pipe 2 is ensured to be smoothly broken at the groove, and the width of the groove is set to be 1 mm. Under the prerequisite that does not influence body structural strength, the recess also can set up to dovetail groove or V type groove, and the thick liquids of being convenient for break after solidifying is demolishd.

In order to avoid concrete slurry from flowing out of the transparent communicating pipe 2, a sealing plate 3 is arranged at the upper end opening of the transparent communicating pipe, and the sealing plate is fixedly connected with the vertical pipe orifice of the transparent communicating pipe.

In order to ensure that the slurry smoothly flows into the transparent communicating pipe 2, the air in the transparent communicating pipe needs to be evacuated successively, and a plurality of air holes 5-2 are arranged on the sealing element, as shown in the figure. Since the air holes 5-2 of the sealing plate 3-2 only have the air permeability, the diameter of the air holes is set to be 1mm in order to prevent the slurry from flowing out of the air holes 5-2.

Further, in order to ensure the sealing performance and avoid the outflow of slurry, a filtering membrane is arranged between the sealing plate 3-2 and the transparent communicating pipe. For example, the waterproof breathable film, the filtration membrane can make the air discharge smoothly, prevents thick liquids from flowing from the bleeder vent simultaneously, further avoids extravagant thick liquids.

In order to ensure the grouting fullness inside the sleeve, the height of the transparent communicating pipe 2 is higher than that of the inner space of the sleeve. According to the communicating vessel principle, when slurry flows into the transparent communicating pipe from the sleeve slurry outlet 7, the liquid level continuously rises and reaches the top end of the transparent communicating pipe 2, the sleeve grouting in the assembly type building component is considered to be completed, and the fullness is high and no gap exists.

On the other hand, the invention provides a use method of the sleeve grouting fullness observer, which comprises the following steps:

step 1: connecting the observer with a grout outlet (7) of the sleeve;

step 2: grouting the sleeve from a grouting port (8);

and step 3: when the concrete slurry in the observer reaches the position of the scale mark, the observer is considered to be fully grouted and sealed, and grouting is stopped at the same time;

and 4, step 4: and removing the observer after the slurry is solidified.

The specific operation of the connection mode is as follows:

the observer for the degree of fullness of grouting of the sleeve can adopt various connection modes, and according to the technical scheme provided by the embodiment, the connection mode of the observer and the grout outlet (7) of the sleeve in the step 1 comprises the following steps: the connecting piece 1 is bonded, screwed or spliced with the wall double-faced adhesive tape.

Installing the double-sided adhesive tape bonded observer:

s1: tearing off the surface paster of the double-sided adhesive tape arranged on the outer side of the connecting piece;

s2: extending the ventilation positioning pipe 4 into the sleeve from the grout outlet 7;

s3: adjusting the observer to enable the vent positioning tube 4 to vertically face upwards and abut against the upper end inside the sleeve;

s4: the viewer is adhered to the exterior surface of the building component.

Installing a threaded observer:

a1: the sleeve grouting fullness observer is screwed into the sleeve grout outlet 7 in a rotating manner;

a2: when the broken structure 9 is level with the surface of the building, the micro-adjustment observer enables the observer to be vertically upward, and installation is completed.

Installing a plug-in type observer:

b1: keeping the observer vertically upwards, and inserting the observer into the sleeve grout outlet 7;

Due to the complex environment of the construction site, such as the damp or uneven surface of the building component, the adhesion effect of the double-sided adhesive tape can be affected, and the connection tightness is affected. And the connecting piece 1 provides a bonding surface for the double-sided adhesive tape to connect the observer with the building component, but under the condition that the sleeves are closely arranged by using a plurality of sleeve grout outlets, the connecting piece 1 cannot provide enough installation space.

Therefore, there is a need for a sleeve grout fullness scope equipped with a threaded connection or socket, preferably a threaded connection, which is a reliable connection means that is not affected by the building element structure and the ambient temperature.

However, when slurry leakage occurs and slurry is required to be supplemented, the installation and matching of the threads are affected due to the existence of slurry at the slurry outlet 7, and the double-sided adhesive tape is not easy to bond.

Because the grafting generally adopts interference fit, is a more strenuous mounting means, consequently, generally adopts threaded connection or adopts the double faced adhesive tape to bond under the high and prerequisite that does not influence the double faced adhesive tape bonding fastness of building element surface smoothness to be comparatively convenient mounting means.

The specific operation of the sealing mode is as follows:

for sealing the observer when the grout is full as described in step 2, the above embodiment provides two ways: the two air holes are staggered or the air holes with small apertures are adopted.

For the first type, a first air hole 5 and a second air hole 6 are respectively arranged on a sealing cover 3 and a transparent communicating pipe 2, the observer is installed at the position of a grout outlet 7 in the state that the first air hole 5 is aligned with the second air hole 6, when grouting reaches the position of a scale mark, the grouting is full, then the sealing cover 3 is rotated, the two air holes are in a staggered state, the sealing cover 3 blocks the second air hole 6, and the sealing cover 3 is in threaded connection with the transparent communicating pipe 2, so that the sealing performance of the observer can be ensured.

For the second sealing mode, a mode that an air hole 5-2 with the size smaller than 1mm is arranged and a sealing plate 3-2 is adopted, because concrete slurry has larger particles and cannot flow out from a tiny hole diameter, further, in order to ensure reliable sealing, a breathable film is arranged between the sealing plate 3-2 and a transparent communicating pipe 2, the breathable film is generally waterproof and breathable film, water vapor can freely permeate through the breathable film, but liquid water can be prevented from permeating through the breathable film, the slurry can be prevented from permeating through the breathable film, the phenomenon that the slurry cannot enter the observer and form a communicating vessel with a sleeve due to the fact that gas in the observer cannot be discharged is avoided, the use effect of the observer is ensured while the slurry is prevented from being wasted

In summary, for the observer with the sealing cover 3, the sealing cover 3 is rotated to make the first air hole 5 and the second air hole 6 dislocated to seal; for the observer provided with the sealing plate 3-2, the air holes 5-2 are air permeable and do not leak slurry.

Regarding the specific operation of the observer removal:

the method for removing the observer in the step 4 comprises the following steps: and removing the connecting piece 1 at the position of the double-sided adhesive tape, breaking and detaching the broken structure 9, and screwing off the observer by rotating the threads or directly detaching the observer.

And for the connection mode that the observer is adhered to the surface of the building component by adopting the double-sided adhesive tape, the observer can be directly detached from the double-sided adhesive tape.

For the connection mode of adopting threaded connection or plug-in connection, the observer is broken and detached from a breaking structure 9 arranged on the observer.
