Prefabricated building is widely used. The so-called prefabricated building is a building where prefabricated parts and components produced in a factory are assembled on the construction site. Prefabricated component factory production replaces on-site pouring by workers. Prefabricated buildings reduce the surrounding production waste and reduce the pollution to the surrounding environment.

The connection between the various formed beams, slabs and walls of the assembled building is connected by a steel sleeve. The two ends of the sleeve are respectively connected to two steel bars. In order to make the combination of the sleeve, the component and the steel bar as a whole, the sleeve A concrete grouting material is injected into the cylinder. After the grouting material is solidified, the sleeve and the reinforcing steel at both ends are firmly combined.

Example one

A sleeve grouting fullness monitor disclosed in this embodiment, referring to FIGS. 1 and 2, includes: a first transparent communication tube 1-1 and a sealing structure; in order to facilitate the observation of the height of the grout surface, the first transparent The communication tube 1-1 can be a transparent rigid plastic tube, which is convenient for use and cost-saving.

The first transparent communication tube 1-1 is connected to the sleeve outlet and forms a communicating device with the inner space of the sleeve to observe whether the sleeve is full. The first transparent communication tube 1-1 is a bent structure, including: a first horizontal tube 1-21 and a first vertical tube 1-22. The first vertical tube 1-22 and the first horizontal tube 1-21 are perpendicular or obtuse to each other. When they are perpendicular to each other, as shown in FIGS. 1 and 2, in order to allow the slurry to flow smoothly, the first transparent communicating tube 1- 1The middle part adopts round corner transition design.

The sleeve grouting fullness monitor of this embodiment uses the principle of a connector, the first transparent communication tube 1-1 communicates with the grouting space inside the sleeve, and the first vertical tube 1-22 of the first transparent communication tube 1-1 The height is higher than the inner space of the sleeve. By observing the height of the concrete slurry in the transparent communication pipe, it is determined whether the inner space of the sleeve is full.

In order to prevent the slurry from overflowing from the first transparent communication tube 1-1, a sealing plate 1-31 or a sealing cover 1-32 is provided for sealing.

Sealing method 1: As shown in FIG. 1, a sealing plate 1-31 is provided on the upper port of the first transparent communication tube 1-1, and the sealing plate 1-31 is fixedly connected to the nozzle of the first vertical tube 1-22. In order to ensure the smooth flow of the slurry into the first transparent communication tube 1-1, it is necessary to successively evacuate the air inside the transparent communication tube, and a plurality of first exhaust holes 1-51 are provided on the sealing plate 1-31.

Since the first vent hole 1-51 on the sealing plate 1-31 has only a breathable effect, and the slurry needs to be prevented from flowing out from the first vent hole 1-51, the aperture size of the first vent hole 1-51 needs to be limited For example, set the diameter of the first exhaust hole 1-51 not more than 2mm. The sealing plate 1-31 is used for venting and evacuating the gas in the transparent communication tube during grouting to facilitate grouting. After the grouting is completed, the monitor is sealed to prevent the slurry from flowing out and wasting the slurry and maintaining the cleanliness of the grouting.

Sealing method 2: As shown in FIG. 2, in order to avoid the outflow of concrete slurry from the first transparent communication tube 1-1, the mouth of the first vertical tube 1-22 of the first transparent communication tube 1-1 is provided with Rotatable sealing cap 1-32. The diameter of the inner hole of the sealing cover 1-32 is the same as the outer diameter of the transparent communication tube. In order to ensure the tightness, the sealing cover 1-32 and the first transparent communication tube 1-1 are connected by a screw.

In order to avoid that the air inside the monitor cannot be smoothly discharged during grouting, the side of the first transparent communication tube 1-1 is provided with a second vent hole 1-6, and the side of the sealing cover 1-32 is provided with a second vent hole 1 -6 corresponds to the first vent hole 1-52. When in use, the first ventilation hole 1-52 is opposite to the second ventilation hole 1-6, which can ensure that the slurry flows into the transparent communication tube and then evacuates the air inside the transparent communication tube. When the slurry in the transparent communication tube reaches a certain height, the sleeve is judged When the grouting is full, the sealing cap 1-32 is rotated to dislocate the first ventilation hole 1-52 and the second ventilation hole 1-6, completely sealing the first transparent communication tube 1-1, preventing the outflow of the slurry, and avoiding waste of the concrete slurry. The sealing cover 1-32 is used to vent the gas in the transparent communication tube during grouting to facilitate grouting. After the grouting is completed, the monitor is sealed to prevent the slurry from flowing out and wasting the slurry;

Or, limit the aperture size of the first exhaust hole 1-51, for example, a vent hole with a diameter of less than 2 mm is opened at the top of the sealing cover 1-32, and the slurry is prevented from overflowing on the premise of achieving ventilation.

Further, in order to ensure that the sleeve grouting monitor is tightly connected to the sleeve grouting port, there will be no leakage of grouting or falling off due to grouting pressure, the sleeve grouting port and the first horizontal pipe 1-21 are connected or inserted through the thread Then fixed installation.

The threaded connection can ensure the close combination of the monitor and the pulp outlet, and can ensure that the monitor and the sleeve pulp outlet are tightly connected.

Installation method 2: There are many ways for plug-in connection, the most commonly used is the interference fit, so that the outer diameter of the first horizontal tube 1-21 of the monitor is slightly larger than the hole diameter of the pulp outlet, and the monitor can also be connected to the outlet The pulp mouth is tightly connected. In order to facilitate the connection of the interference fit, a chamfer can be processed at the port of the first horizontal tube 1-21 to facilitate the smooth insertion of the horizontal tube into the sleeve outlet.

Since the first horizontal tube 1-21 and the sleeve outlet form a tight whole after the slurry is solidified, in order to facilitate the removal of the monitor after the slurry is solidified, the first horizontal tube 1-21 is placed near the nozzle There is a broken structure, for example, a broken groove 1-4, and the broken groove is an annular groove on the outer side of the first horizontal tube 1-21.

As shown in Figures 1 and 2, because the first horizontal pipe 1-21 is screwed to the sleeve outlet, after tightening the monitor and the sleeve outlet, the break groove 1-4 is located in the plane of the outlet Place, flush with the wall. After the slurry solidifies, the monitor is broken from the groove, which can keep the construction site clean, and can also keep the wall flat and beautiful.

Preferably, in order to facilitate the removal of the monitor after the grouting is completed, the first transparent communication tube 1-1 is smoothly broken at the groove, and the width of the groove is set to 1 mm. On the premise of not affecting the structural strength of the pipe body, the groove can also be set as a trapezoidal groove or a V-shaped groove, which is convenient for breaking and removing after the slurry solidifies.

Considering that the concrete slurry has a certain viscosity, the first transparent communication tube 1-1 is a bent structure. In order to ensure the smooth circulation of the slurry in the transparent communication tube, the first vertical tube 1-22 of the transparent communication tube and the first level The tubes 1-21 are of an integrated structure with rounded corners. For the specific structure, see Figure 1.

Further, in order to facilitate the connection of the sleeve grouting fullness monitor and the sleeve outlet, a plurality of gear rings are provided on the outside of the body of the first horizontal pipe 1-21, and the gear ring is a ring-shaped structure with a triangular or trapezoidal cross section . The first horizontal pipe 1-21 is inserted and installed with the sleeve slurry outlet, that is, the installation is achieved by the interference fit of the gear ring and the sleeve slurry outlet. Specifically, there are multiple tooth rings, whose diameters increase in sequence, and the end with the smaller diameter of the tooth ring is inserted into the slurry outlet of the sleeve. Since the diameter of the ring gear increases sequentially, the sleeve grout fullness monitor of this embodiment can be connected and fixed to the sleeve grout with different calibers by interference fit.

Further, if the internal grouting sleeve is leaking, the sealing cap 1-32 can be removed from the first vertical tube 1-22 and directly from the nozzle of the first vertical tube 1-22 of the monitor Carry out filling.

Further, in order to facilitate the connection between the monitor and the slurry outlet of the sleeve, a square platform is provided on the outside of the transparent communication tube body, and the side plane of the square platform serves as the force application plane when the monitor is installed.

Further, an anti-sticking treatment is performed on the inner tube wall of the first transparent communication tube 1-1, for example, anti-sticking paint can be applied to prevent the slurry from adhering to the tube wall and affecting the observation effect.

Further, the first transparent communication tube 1-1 can be made into a form of repeated use, for example: spliced from two symmetrical shells, when used, the assembled pieces are observed, and after the grouting is completed, the monitor is sealed Remove the cover, open the communication tube, remove the slurry inside the monitor, clean it and reuse it.

In order to ensure the fullness of the grout inside the sleeve, the height of the first vertical tube 1-22 of the transparent communicating tube is higher than the height of the space inside the sleeve. According to the principle of the connecting device, a scale mark, such as a scale line, is marked on the outside of the first vertical tube 1-22 of the transparent communication tube. After the installation of the monitor, the height of the scale mark is consistent with the top of the inner space of the sleeve. When the slurry flows into the transparent communication tube from the sleeve outlet, the liquid level continues to rise. When the scale mark position is reached, the sleeve grouting in the assembled building component is considered to be full. At this time, the rotary sealing cover 1-32 seal monitoring To avoid waste caused by slurry outflow.

Example 2

The sleeve grouting fullness monitor disclosed in this embodiment, as shown in FIG. 3, includes: a second transparent communication tube 2-1, a first sealing plug 2-2 and a first elastic member 2-3, which can be more intuitive Observe whether the sleeve grouting is full. A first elastic member 2-3 is provided between the first sealing plug 2-2 and the upper end of the second transparent communication tube 2-1; the first elastic member 2-3 can make the first sealing plug 2-2 transparent at the second The communication pipe 2-1 moves inside, and the position of the first sealing plug 2-2 is higher than the height of the inner sleeve.

The first elastic member 2-3 is provided between the first sealing plug 2-2 and the fixing member.

Preferably, the first elastic member 2-3 is a spring or a leaf spring.

Specifically, the second transparent communication tube 2-1 may be directly or indirectly connected to the slurry outlet of the sleeve. When indirectly connected, a connection tube transition is adopted in the middle.

Preferably, the lower end of the second transparent communication tube 2-1 is used to connect the sleeve outlet hole.

Preferably, the first sealing plug 2-2 is provided inside the upper end of the second transparent communication tube 2-1 to prevent the slurry from overflowing; considering that the slurry leakage phenomenon may occur after the connection sleeve is grouted. The level of slurry in the second transparent communication tube 2-1 drops. By observing whether the level of the slurry in the second transparent communication tube 2-1 drops, it can be judged in time whether the slurry leakage phenomenon occurs.

However, since the slurry inside the sleeve and the monitor may be in different temperature environments, the slurry in various parts will appear to be out of synchronization. Due to the difference in slurry solidification speed and solidification degree, it may happen that the slurry plane in the monitor does not drop when slurry is leaking.

In addition, the concrete slurry tends to stick to the wall of the second transparent communication tube 2-1, which causes a phenomenon that the slurry level is not easily observed when the slurry leaks.

In view of the above problems, a first elastic member 2-3 is provided between the upper end of the first sealing plug 2-2 and the upper end of the second transparent communication tube 2-1, and the slurry is injected into the second transparent communication tube 2- during grouting 1 and the slurry has a certain pressure. As the slurry level rises, the first sealing plug 2-2 can compress the first elastic member 2-3 to complete the grouting. When the slurry leakage phenomenon occurs, the upward pressure support of the slurry is lost under the sealing plug, and it moves downward under the action of the spring force. Observe whether the first sealing plug 2-2 is pushed downward by the spring to determine whether there is a slurry leakage phenomenon .

Preferably, in order to facilitate observation, the second transparent communication tube 2-1 is made of transparent plastic material, and the first sealing plug 2-2 is made of black rubber or plastic material. One end of the spring is fixed on the top of the communication tube, and the other end is fixed on the first sealing plug 2-2.

In order to ensure that the second transparent communication tube 2-1 is smoothly broken at the groove, the width of the groove is set to 1 mm. On the premise of not affecting the structural strength of the pipe body, the groove can also be set as a trapezoidal groove or a V-shaped groove, which is convenient for breaking and removing after the slurry solidifies.

Further, in order to facilitate the connection between the sleeve grouting fullness monitor and the sleeve outlet, a plurality of gear rings are provided on the outside of the body of the second transparent communication tube 2-1, and the gear rings are ring-shaped with a triangular or trapezoidal cross section structure. The second transparent communication tube 2-1 is inserted and installed with the sleeve outlet, that is, the installation is achieved by interference fit of the gear ring and the sleeve outlet. Specifically, there are multiple tooth rings, whose diameters increase in sequence, and the end with the smaller diameter of the tooth ring is inserted into the slurry outlet of the sleeve. Since the diameter of the ring gear increases sequentially, the sleeve grout fullness monitor of this embodiment can be connected and fixed to the sleeve grout with different calibers by interference fit.

Specifically, according to the position of the sleeve in the building component in actual working conditions, the second transparent communication tube 2-1 may be designed as a transparent straight tube or a transparent bent tube. When the sleeve inside the building component is placed horizontally, the sleeve The pulp outlet of the wall surface of the pulp outlet part is vertically upward. At this time, the second transparent communication pipe 2-1 is designed as a transparent straight pipe. If the sleeve is placed vertically in the component, the slurry outlet is horizontal. Therefore, in order to make the slurry surface in the communication tube of the monitor higher than the height of the slurry surface in the sleeve, the second transparent communication tube 2-1 is designed It is a bent tube, and the top is upright when installing.

Further, a scale is marked on the second transparent communication tube 2-1, which is convenient for judging whether the inner sleeve is full of grout.

Further, an anti-sticking treatment is performed on the inner tube wall of the second transparent communication tube 2-1, for example, anti-sticking paint can be applied to prevent the slurry from adhering to the tube wall and affecting the observation effect.

Further, the second transparent communication tube 2-1 can be made into a form of repeated use, for example: spliced from two symmetrical shells, when used, the splicing is observed, and after the grouting is completed, the monitor is sealed Remove the cover, open the communication tube, remove the slurry inside the monitor, clean it and reuse it.

Compared with the prior art, the sleeve grouting fullness monitor provided in this embodiment is provided with a first sealing plug 2-2 and a first elastic member 2-3.
