Description

The present invention belongs to the technical field of waterproofing by sealing the joints of the outer walls of buildings, and in particular, the joints of the outer walls of prefabricated buildings (hereinafter referred to as "assembled walls") are waterproofed by filling them with a foaming agent. The present invention relates to a waterproofing device and a waterproofing method.

In the construction industry, prefabricated buildings are trending because they have many advantages such as high building quality, construction efficiency, climate resistance, and short cycle time. It also has the characteristics of environmental protection.
At present, the construction technology of prefabricated buildings is widely used in the construction industry and is used to varying degrees in almost all buildings, for example industrial plants, villas, large public buildings, especially multi-storey houses. It is

However, there is a gap created during assembly between the assembled walls of the prefabricated building, and this gap needs to be waterproofed and sealed.
For example, when the foaming agent is filled into the gap, the foaming agent has a porosity, so it is soft and difficult to identify, and it is difficult to achieve full automation to increase the filling efficiency.
Conventionally used rubber material seals need to be crimped manually. Time elapses between the first and the crimping, and dust and the like enter during that time, which may affect the effectiveness of the seal.

For example, specification [0020] of Patent Document 1 discloses a slit-type powder filling device having a supply hopper for supplying powder, a slit-shaped discharge port, and a powder discharge slit for discharging the powder supplied from the supply hopper. It is
According to this, the inorganic foamed particles can be stably and continuously spread over the substrate, and at the same time, the surface of the spread inorganic foamed particles can be smoothed. Continuous production of composite building materials is also possible by continuously supplying inorganic foamed particles from a slit-type powder filling device and spreading them.

However, in the invention described in Patent Document 1, in order to continuously supply and spread the inorganic foamed particles, it is necessary to transfer the base material while placing it on a conveyer, and the device itself needs to continuously feed and spread the inorganic foamed particles. It cannot be filled with blowing agents.
Further, there is no disclosure of means for detecting the completion of filling and automatically stopping filling at that timing.

The trigger piece 63 is inserted through the second notch 69, and when the trigger piece 63 swings in the front-rear direction of the foaming agent discharge head 39, the hinge shaft 64 rotates within the support lug 46 in accordance with the movement. do.
That is, the trigger piece 63 slides in the longitudinal direction of the foaming agent discharge head 39 while being inserted into the second notch 69 of the hinge shaft 64. 64 rotates within the support lugs 46;

Mounted within the blowing agent discharge head 39 is a third motor 51 supported by a fourth support 52, as shown in FIGS.
A pendulum plate 61 having a thick flat plate shape is connected to a rotating shaft 59 that is an output shaft of the third motor 51 .
The pendulum plate 61 is connected with the first elastic piece 67 as shown in FIG.
The first elastic piece 67 is connected with the trigger piece 63 .

When the third motor 51 is driven, the pendulum plate 61 moves backward (to the left in the upper diagram of FIG. 16) in accordance with the rotation of the rotation shaft 59 of the third motor 51, and moves like a pendulum around the rotation shaft 59 as a fulcrum. swing to.
When the pendulum plate 61 swings, the first elastic piece 67 connected to the pendulum plate 61 slides along the guide surface 50 on the guide surface 50 .
Then, the trigger piece 63 connected to the first elastic piece 67 slides rearward (to the left in the upper diagram of FIG. 16).

The first slide plate 71 is sandwiched between two guide plates 74, and is pulled from the pendulum plate 61 in accordance with the swing of the pendulum plate 61 (movement like a pendulum to the left in the upper diagram of FIG. 16). It slides between the two guide plates 74 diagonally upward to the left and diagonally downward to the right in FIG.

The first slide plate 71 is toothed and meshes with the third gear 75 .
The third gear 75 also meshes with the second slide plate 72 arranged on the opposite side of the first slide plate 71 .
Therefore, when the first slide plate 71 slides, the third gear 75 rotates accordingly, the tooth profile is formed, and the second slide plate 72 meshing with the third gear 75 is also obliquely upward left and diagonally right in FIG. Slide down in each direction.
As shown in FIG. 18, the second slide plate 72 is in contact with the guide block 73 and slides along the contact surface with the guide block 73 .

The two guide plates 74, the third gear 75, and the guide block 73 are attached so as to be sandwiched between the sixth support 66 fixed to the first elastic piece 67, as shown in FIG.

When the first slide plate 71 slides in the upper left direction in FIG. 18, the removal block 62 attached to the tip of the first slide plate 71 moves in the upper left direction in FIG.
Further, when the first slide plate 71 slides in the upper left direction in FIG. 18, the second slide plate 72 meshing with the third gear 75 also slides in the lower right direction in FIG. The position of the removal block 62 attached to the tip of the is moved in the diagonally lower right direction in FIG.
That is, when the third motor 51 is driven and the pendulum plate 61 swings backward (to the left in the upper diagram of FIG. 16) in accordance with the rotation of the rotation shaft 59 that is the output shaft of the third motor 51, the pendulum plate As pulled by 61, the telescopic support 70 is pulled diagonally to the upper left in FIG.
Then, the first slide plate 71 is pulled by the telescopic support 70 to slide in the upper left direction in FIG. 18, and at the same time, the second slide plate 72 slides in the lower right direction in FIG. Therefore, the distance between the removal blocks 62 attached to the ends of the first slide plate 71 and the second slide plate 72 is narrowed.

A trigger piece 63 is positioned between the two removal blocks 62, as shown in FIG.
The trigger piece 63 is driven by the third motor 51 to slide rearward (to the left in the upper diagram of FIG. 16) in accordance with the movement of the pendulum plate 61, but the sharp tips of the two removal blocks 62 As 71 and second slide plate 72 slide, the distance narrows until both the upper and lower sides of trigger piece 63 come into contact with trigger piece 63, and finally, trigger piece 63 moves backward (see FIG. 16). ), the sharp tips of the two removal blocks 62 come into contact with the top and bottom sides of the trigger piece 63 .
That is, the trigger piece 63 slides rearward (to the left in the upper diagram of FIG. 16) while the sharp tips of the two removal blocks 62 are in contact with its upper and lower surfaces.

The tip of the trigger piece 63 (the right side in the upper diagram of FIG. 16) has a shape that is slightly bent upward, and the sharp tips of the two removal blocks 62 are still in contact with this tip. , the trigger piece 63 slides rearward (to the left in the upper diagram of FIG. 16).
At this time, the elastic support 70 having the spring 60 inside expands and contracts due to the elastic force of the spring 60, and the sharp tips of the two removal blocks 62 move to the tip of the trigger piece 63 (right side in the upper diagram of FIG. 16). The contact position can be corrected according to the slightly curved shape of the
In this way, the trigger piece 63 is moved rearward (left side in the upper drawing of FIG. 16, inside the foaming agent discharge head 39) with sharp tips of the two removal blocks 62 in contact with its top and bottom sides. 13, by the sharp tips of the two removal blocks 62 at the positions protruding from the fourth guides 45 formed in the openings just above and below the discharge port of the foaming agent discharge passage 44, as shown in FIG. , the foaming agent adhering to the trigger piece 63 can be removed from the trigger piece 63 .

By the way, at the tip of the front side of the guide surface 50 of the foaming agent discharge head 39, a first notch portion 49 is formed by cutting the central portion of the foaming agent discharge head 39 in the front-rear direction (only both sides are left). However, the first notch 49 is such that a second elastic piece 68 extending from a trigger piece 63 that slides rearward (to the left in the upper diagram of FIG. 16) in accordance with the movement of the pendulum plate 61 is positioned on the guide surface 50. to prevent interference with
That is, the guide surface 50 has the same width as the pendulum plate 61, but is slightly narrower than the pendulum plate 61, and the second elastic piece 68, which has the same width as the first elastic piece 67, has the same cut as the first notch 49. Because of the cutout width, even if the second elastic piece 68 slides near the guide surface 50 in accordance with the slide of the trigger piece 63, the formation of the first notch 49 interferes with the guide surface 50. never

The foaming agent is discharged from the tip opening of the foaming agent discharge path 44 of the foaming agent discharge head 39, and when the discharge destination is sufficiently filled with the foaming agent, the foaming agent is filled to the vicinity of the tip of the foaming agent discharge head 39. will be
In this state, the foaming agent presses the trigger piece 63 located at the opening just above or below the ejection port of the foaming agent discharge passage 44 toward the interior of the foaming agent ejection head 39 .
The trigger piece 63, which is pressed by the foaming agent and positioned at the opening directly above or below the outlet of the foaming agent discharge passage 44, swings about the hinge shaft 64 to reach the back surface of the second elastic piece 68. The attached pressure sensor 65 comes into contact with a convex support block 47 formed on the front end portion of the extrusion surface 48 .
When the pressure sensor 65 touches the support block 47, as already explained, it sends a signal to the control module incorporated in the device according to the invention, which drives the third motor 51. FIG.
When the third motor 51 is driven, the trigger piece 63 slides into the foaming agent discharge head 39, and the sharp tips of the two removal blocks 62 remove the foaming agent adhering to the trigger piece 63 as described above. Remove from 63.
Note that when the pressure sensor 65 sends a signal to the control module, the control module stops the foaming agent raw material hopper 33 from discharging the foaming agent.

Further, when the pressure sensor 65 sends a signal to the control module, the control module drives the second motor 34 .
When the second motor 34 is driven, the second motor 34 rotates the second screw 37 , and as the second screw 37 rotates, the mounting slider 36 slides on the lower surface side of the lifting platform 2 .
The foaming agent raw material hopper 33 connected to the foaming agent extrusion pipe 38 slides on the upper surface side of the lifting table 2 in accordance with the sliding movement of the mounting slider 36 .
This slide movement retracts the blowing agent discharge head 39 from the filling destination.
When filling the foaming agent, the second screw 37 is reversely rotated by the second motor 34 in order to advance the foaming agent discharging head 39 .

After filling with the foaming agent, the gap in the assembly wall 1 is sealed by the sealing module 10 .
As shown in FIGS. 7, 8 and 10, the sealing module 10 is connected to a sealing agent hopper 19 that stores the raw material of the sealing agent, and to the sealing agent hopper 19 to push the sealing agent stored in the sealing agent hopper 19 away. A sealant extruder 28, a sealant discharger 20 for discharging the sealant from the discharge port through the sealant extruder 28, a discharge port for discharging the sealant from the sealant discharger 20, and the discharged sealant , a mounting plate 21 on which the sealing module 10 is placed, and a heat sensing module 18 for sensing the heat of the sealant.
The thermal sensing module 18 and mounting plate 21 are mounted on a second support 27 depending from the underside of the platform 2, as shown in FIGS.
Therefore, the ceiling module 10 moves vertically up and down in accordance with the lift table 2 .
The sealant discharger 20 includes a heating module that heats the sealant and a screw-type extrusion module that discharges the heated and melted sealant.

The thermal sensing module 18 includes a tank 17, a pump 77, a water pipe 23, a thermal sleeve 22, a heat pipe 26, and a thermal plate 24, as shown in FIG.
Water is stored in the tank 17, and the pump 77 pumps the water stored in the tank 17 through the water pipe 23 to the thermal sleeve 22 connected to the water pipe 23 as shown in FIG. circulate inside.
As shown in FIG. 8, the heat pipe 26 is fixed by the first support 25 attached to the side of the second support 27, and water is stored inside like the tank 17. do not circulate.
One end of the heat pipe 26 is inserted into the heat sensitive sleeve 22 , and the water inside the heat pipe 26 is warmed through the heat sensitive sleeve 22 .
The other end of the heat pipe 26 is attached to the heat-sensitive plate 24, and the water in the heat pipe 26 heated by the heat-sensitive sleeve 22 is transmitted to the heat-sensitive plate 24 to change the color of the heat-sensitive plate 24 according to the temperature.
As shown in FIG. 6, the elevator table 2 is formed with a mounting groove 16 for attaching a thermal plate 24 , and the thermal plate 24 is attached to the elevator table 2 by the mounting groove 16 .

When the sealant is discharged from the outlet of the molded plate 30, the sealant is melted into a liquid state by heat, and is gradually accumulated from below in the gap between the filled foaming agent and the molded plate 30. .
When the stored liquid sealant reaches the height of the heat-sensitive sleeve 22, the heat of the sealant is transmitted to the heat-sensitive sleeve 22, and further from the heat-sensitive sleeve 22 to the heat-sensitive plate 24 through the heat pipe 26, whereupon the heat-sensitive plate 24 colors change.
In this way, it can be determined that the sealant has been discharged up to the height of the heat-sensitive sleeve 22 by using the color change mechanism of the heat-sensitive plate 24 .

The third motor 51 drives the trigger piece 63 for the purpose of drawing it into the foaming agent discharge head 39 , but at the same time drives the pump 77 to push cold water in the tank 17 through the water pipe 23 into the thermal sleeve 22 . to cool the thermal sleeve 22.
When the heat-sensitive sleeve 22 is cooled, the water stored in the heat pipe 26 inserted into the heat-sensitive sleeve 22 at one end is cooled, lowering the temperature of the heat-sensitive plate 24 and restoring the heat-sensitive plate 24 to its original color.
After a preset period of time, the pump 77 will automatically stop and stop circulating the cold water in the tank 17 through the thermal sleeve 22 .
Then, when the sealant is discharged from the discharge port of the molding plate 30, the same process is repeated.

The molding plate 30 functions to shape the surface of the sealant by pressing the sealant discharged to the front side of the foaming agent filled in the gap of the assembly wall 1 from the outside of the assembly wall 1 into the gap. fulfill
By molding the sealant, the filling amount of the sealant can be saved and the appearance of the outer wall can be improved.
As shown in FIG. 10, a mounting piece 29 is attached to the upper surface of the molding plate 30, and a masking piece 31 is hinged to the mounting piece 29. has a leaf spring 32 attached.

A masking piece 31 attached by a leaf spring 32 to the mounting piece 29 prevents expulsion of the sealant beyond the height of the foam filling and serves to limit the amount of expelled sealant.
If the sealant is discharged without any space limitation, the heat of the sealant will not be easily transmitted to the heat-sensitive sleeve 22, and a large amount of sealant will be discharged beyond the height of the foaming agent filled, and the filling of the foaming agent will be interrupted. It might get in the way.
Therefore, by limiting the movement of the masking piece 31 with the repulsive force of the leaf spring 32 so that the masking piece 31 does not rise above the height of the mounting piece 29, the sealant does not exceed the height of the mounting piece 29. It is possible to limit the space in which the sealant is discharged.
As a result, an optimum amount of sealing agent can be discharged to the height where the foaming agent is filled, and the gaps in the assembly wall 1 can be closed.

A description will be given of a method of using the waterproofing device for outer wall joints of a prefabricated building according to the present embodiment and a waterproofing method using the device.
The device according to this embodiment is moved between two assembled walls 1 where the gap needs to be sealed.
Before filling the foaming agent, a plug 6 is inserted into the gap of the assembly wall 1 on the side opposite to the side filled with the foaming agent.
The plug 6 is not a part that constitutes the apparatus according to this embodiment, but plays a role in preventing the foaming agent filled in the assembly wall 1 from leaking out from the gap on the side opposite to the filled side. Since the gap is closed with a sealant, the foaming agent will not leak from the gap of the assembly wall 1.).
Therefore, instead of the plug 6, a sealing tape can be substituted. When the sealing tape is substituted, the sealing tape is affixed to all the gaps of the assembly wall 1 in advance.

The first motor 5 is driven to rotate the first screw 8.
As the first screw 8 rotates, the lift table 2 moves vertically along the guide frame 7 .
The first motor 5 is stopped after the foaming agent discharge head 39 is moved up and down according to the height at which the foaming agent is filled.

The second motor 34 is driven to rotate the second screw 37 .
As the second screw 37 rotates, the attachment slider 36 slides on the lower surface side of the lift table 2 .
Along with the sliding movement of the mounting slider 36, the foaming agent raw material hopper 33 connected to the foaming agent push-out pipe 38 slides on the upper surface side of the lifting table 2, and the foaming agent discharge head 39 connected to the foaming agent push-out pipe 38 slides. do.
A blowing agent discharge head 39 is inserted between the two assembly walls 1 and positioned in the gap.
At this time, the foaming agent discharge head 39 should not be inserted all the way into the gap.

Once the foaming agent discharge head 39 is positioned within the gap in the assembly wall 1, the foaming agent is discharged to fill the gap.
The filling of the foaming agent is performed while moving the position of the foaming agent discharge head 39 from the back of the gap toward the front (while driving the second motor 34 and sliding the foaming agent discharge head 39 backward).
When the foaming agent is sufficiently filled under the gap of the assembled wall 1, this is defined as the first layer.

After the blowing agent discharge is stopped, the operator manually controls the sealant extruder 28 to discharge the sealant in front of the charged foaming agent.
When the discharged sealant changes the color of the heat-sensitive plate 24, the worker manually stops the discharge of the sealant.
This completes the sealing of the first layer.

After that, the lift table 2 is lifted, and the foaming agent is filled in the gaps of the assembly wall 1 so that the second layer overlaps the first layer.
After filling the foaming agent, the operator manually controls the sealant extruder 28 to discharge the sealant, and manually stops the discharge of the sealant when the color of the heat-sensitive plate 24 changes.
In this manner, the charging of the foaming agent and the discharging of the sealing agent are repeated multiple times.
As a result, the gap in the assembly wall 1 filled with the foaming agent can be immediately closed with the sealant after filling with the foaming agent, and the gap can be sealed without allowing dust or the like to enter the gap.

When the filled foaming agent presses the trigger piece 63, the control module receiving the signal from the pressure sensor 65 stops the foaming agent release.
The retraction speed, retraction width, and upward travel distance during this filling operation are measured and entered into the control platform. Filling can also be done automatically under certain conditions.
