Description

Technical Field

[0001] The invention relates to the technical field of hollowing repair, and in particular to a construction method for repairing hollowing of a floor. Background Art

[0002] Hollowing is caused by the presence of air in the original masonry and powder plaster layer. During testing, use a hollowing hammer or a hard object to tap the plaster layer and leveling layer, and a thudding sound is heard, which is hollowing. "Hollowing" in house quality generally refers to the hollowing phenomenon caused by loose adhesion and bonding between the floor, wall, and ceiling decoration layers (plastering or pasted tiles) and the structural layers (concrete or brick walls) of the house.

[0003] Floor hollowing is mostly caused by dust on the surface of the ground foundation, or cracking and peeling of the painted surface paint. Existing hollowing repairs are usually done by direct grouting. The dust and other debris inside the hollowing area are not cleaned up, which can easily lead to insufficient pressure-bearing capacity and service life of this repair area. Therefore, it is necessary to improve the design of relevant technologies. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a construction method for repairing hollow floor.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A floor hollowing repair construction method comprises the following steps:

[0006] S1. Slide the hollowing hammer on the floor, judge the hollowing boundary by the sound and draw a line to mark it;

[0007] S2. Drill two holes at the edge of the hollow area, and the angle between the center of the hollow area and the two holes is 90 degrees;

[0008] S3. Use the floor hollow repair device to clean the dust and other debris inside the hollow area, and then fill the cleaned hollow area with grout for repair;

[0009] The floor hollowing repair device comprises a trolley body, and a cleaning component for cleaning dust and other debris in the hollow and a repair component for grouting into the hollow are arranged on the top of the trolley body;

[0010] S4. After the hollow is filled with slurry, grind the floor around the drill hole to make the floor flat and complete the floor hollow repair work.

[0011] By adopting the above technical solution, the angle between the center of the hollow area and the line connecting the two holes is 90 degrees. The cleaning component is used to clean from the two drill holes respectively, and cleaning can be carried out in directions perpendicular to each other, thereby enhancing the cleaning effect inside the hollow area and thereby improving the effect of subsequent grouting repair.

[0012] Furthermore, the cleaning assembly includes a vacuum cleaner fixed to the top of the trolley body and an air suction hose fixed to and connected to the air suction port of the vacuum cleaner, and a plurality of air suction ports are evenly arranged on a side of the air suction hose away from the vacuum cleaner.

[0013] By adopting the above technical solution, the suction hose is inserted into the hollow drum through the drilled hole. After the vacuum cleaner is working, the dust and other debris in the hollow drum can be cleaned through the suction hose. Since the angle between the center of the hollow drum area and the connecting line between the two holes is 90 degrees, although the suction hose is a hose, it still has a certain hardness. The suction hose entering the hollow drum from the two drilled holes has extension directions that are basically perpendicular to each other. Such an arrangement can improve the cleaning effect of dust and other debris in the hollow drum.

[0014] Furthermore, a metal hose is provided on the fixed sleeve outside the air suction hose, and a through hole is penetrated through the metal hose at a position corresponding to the dust suction port.

[0015] Furthermore, a plurality of bristles are evenly fixed on the outer wall of the metal hose.

[0016] By adopting the above technical solution, the setting of the metal hose enhances the protection of the air suction hose and reduces the probability of wear of the metal hose by the hollowing in the floor. The setting of the bristles can clean the burrs and other debris attached to the surface, and improve the effect of adsorbing and cleaning the debris in the hollow.

[0017] Furthermore, the repair assembly includes a grouting bucket arranged on the top of the trolley body, a grouting pump fixed to the top of the trolley body, and a grouting hose fixed and connected to the discharge pipe of the grouting pump, and the feed pipe of the grouting pump is fixed and connected to the grouting bucket.

[0018] Furthermore, a plurality of grouting holes are evenly arranged on the grouting hose.

[0019] By adopting the above technical solution, after the grouting pump starts working, the grouting liquid is ejected through the grouting holes on the grouting hose, and the grouting liquid sprayed out with high pressure penetrates into various parts of the hollow drum. After filling the entire hollow drum area, the grouting hose can be pulled out. In the process of pulling out the grouting hose, the grouting pump still needs to be controlled to perform grouting operations on the space in the grouting hose.

[0020] Furthermore, a strong magnet is tied to the top of the grouting hose via a steel wire.

[0021] By adopting the above technical solution, the setting of strong magnets can adsorb iron filings and other debris inside the hollow drum. In addition, the use of magnets to attract the top of the floor in the hollow drum area can fix the relative position of the grouting hose, thereby avoiding the situation where the grouting hose shakes randomly in the hollow drum due to the high grouting pressure and affects the grouting repair effect.

[0022] Furthermore, a fixing rod is fixed on the top of the trolley body, and two elastic clips arranged in parallel are fixed on the top of the fixing rod. A clearing assembly for cleaning the grouting hose after use is provided on the top of the trolley body, and the clearing assembly includes a clearing rod snap-fitted with the elastic clip, a plurality of annular airbags sleeved and fixed on the clearing rod, and a flexible connecting tube for connecting adjacent annular airbags, wherein an inflation tube is fixed on and connected to one of the annular airbags, and a sealing plug snap-fitted with the inflation tube is provided at the end of the inflation tube.

[0023] Furthermore, the distance between adjacent grouting holes in the axial direction of the grouting hose is equal to the distance between adjacent annular air bags.

[0024] By adopting the above technical solution, when the annular airbag is not inflated, the outer diameter of the annular airbag is smaller than the inner diameter of the grouting hose, so that the staff can insert the clearing rod into the grouting hose and clean the inside of the grouting hose by pulling the clearing rod. After opening the sealing plug and inflating the annular airbag through the inflation tube, due to the setting of the soft connecting tube, multiple annular airbags are bulged, so that the grouting hoses at all the slurry outlets are expanded, and the diameter of the side of the slurry outlet away from the clearing rod is close to the diameter of the side of the clearing rod, so that it is convenient for the staff to use the annular brush matched with the grouting hose to clean the residual materials in the slurry outlet, which is conducive to the normal use of the grouting hose next time.

[0025] Furthermore, a rubber ring is sleeved on the blocking rod, the inner diameter of the rubber ring is smaller than the outer diameter of the annular airbag when it is not inflated, a fixing ring is attached to and fixed on the outer wall of the rubber ring, a plurality of anti-slip convex strips are evenly fixed on the outer wall of the fixing ring, and a spiral groove is arranged on the inner wall of the rubber ring.

[0026] By adopting the above technical solution and the provision of the rubber ring and the spiral groove, it is convenient for the staff to clean the debris contaminated on the outer side of the annular airbag by pushing the fixing ring.

[0027] In summary, the present invention has the following beneficial effects:

[0028] 1. In this application, the angle between the center of the hollow area and the line connecting the two holes is 90 degrees. The cleaning assembly is used to clean from the two drill holes respectively, and the cleaning can be done in directions perpendicular to each other, which enhances the cleaning effect inside the hollow area and thus improves the effect of the subsequent grouting repair;

[0029] 2. In this application, the suction hose is inserted into the hollow drum from the drill hole. After the vacuum cleaner is working, the dust and other debris in the hollow drum can be cleaned through the suction hose. Since the angle between the center of the hollow drum area and the connecting line between the two holes is 90 degrees, the suction hose is a hose but still has a certain hardness. The suction hoses entering the hollow drum from the two drill holes extend in directions that are substantially perpendicular to each other. This arrangement can improve the cleaning effect of dust and other debris in the hollow drum.

[0030] 3. In the present application, the setting of a strong magnet can absorb iron filings and other debris inside the hollow drum. In addition, the use of a magnet to attract the top of the floor in the hollow drum area can fix the relative position of the grouting hose, thereby avoiding the situation where the grouting hose shakes randomly in the hollow drum due to the high grouting pressure and affects the grouting repair effect.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0041] like Figure 1-8 As shown, the embodiment of the present application discloses a floor hollowing repair construction method, comprising the following steps:

[0042] S1. Slide the hollowing hammer on the floor, judge the hollowing boundary by the sound and draw a line to mark it;

[0043] S2. Drill two holes at the edge of the hollow area, and the angle between the center of the hollow area and the two holes is 90 degrees;

[0044] S3. Use the floor hollow repair device to clean the dust and other debris inside the hollow area, and then fill the cleaned hollow area with grout for repair;

[0045] The floor hollowing repair device comprises a trolley body 1, and a cleaning component 2 for cleaning dust and other debris in the hollow and a repair component 3 for grouting into the hollow are arranged on the top of the trolley body 1;

[0046] S4. After the hollow is filled with slurry, grind the floor around the drill hole to make the floor flat and complete the floor hollow repair work.

[0047] The angle between the center of the hollow area and the line connecting the two holes is 90 degrees. The cleaning assembly 2 is used to clean from the two drill holes respectively, and cleaning can be carried out in directions perpendicular to each other, thereby enhancing the cleaning effect inside the hollow area and further improving the effect of subsequent grouting repair.

[0048] The cleaning assembly 2 includes a vacuum cleaner 21 fixed to the top of the trolley body 1 and an air suction hose 22 fixed to and connected with the air suction port of the vacuum cleaner 21 . A plurality of air suction ports 221 are evenly arranged on the side of the air suction hose 22 away from the vacuum cleaner 21 .

[0049] Insert the suction hose 22 into the hollow drum through the drilled hole. After the vacuum cleaner 21 starts working, the dust and other debris in the hollow drum can be cleaned through the suction hose 22. Since the angle between the center of the hollow drum area and the connecting line between the two holes is 90 degrees, although the suction hose 22 is a hose, it still has a certain hardness. The suction hose 22 that enters the hollow drum from the two drilled holes has extension directions that are basically perpendicular to each other. Such a setting can improve the cleaning effect of dust and other debris in the hollow drum.

[0050] A metal hose 4 is fixedly sleeved outside the air suction hose 22 . A through hole 41 is penetrated through the metal hose 4 at a position corresponding to the dust suction port 221 . A plurality of bristles 42 are evenly fixed on the outer wall of the metal hose 4 .

[0051] The provision of the metal hose 4 enhances the protective effect on the air suction hose 22 and reduces the probability of wear of the metal hose 4 by the hollowing in the floor. The provision of the bristles 42 can clean the debris attached to the surface such as burrs, thereby improving the effect of adsorbing and cleaning the debris in the hollowing.

[0052] The repair component 3 includes a grouting barrel 31 arranged on the top of the trolley body 1, a grouting pump 32 fixed to the top of the trolley body 1, and a grouting hose 33 fixed and connected to the discharge pipe of the grouting pump 32. The feed pipe of the grouting pump 32 is fixed and connected to the grouting barrel 31, and a plurality of grouting holes 331 are evenly arranged on the grouting hose 33.

[0053] After the grouting pump 32 starts working, the grouting liquid is ejected through the grouting hole 331 on the grouting hose 33. The grouting liquid sprayed out with high pressure penetrates into various parts of the hollow drum. After filling the entire hollow drum area, the grouting hose 33 can be pulled out. In the process of pulling out the grouting hose 33, the grouting pump 32 still needs to be controlled to perform grouting operations on the space of the grouting hose 33.

[0054] A strong magnet 5 is tied to the top of the grouting hose 33 by steel wire. The setting of the strong magnet 5 can absorb iron filings and other debris inside the hollow. In addition, the use of magnets to attract the top of the floor in the hollow area can fix the relative position of the grouting hose 33, avoiding the situation where the grouting hose 33 shakes randomly in the hollow due to the high grouting pressure and affects the grouting repair effect.

[0055] A fixing rod 6 is fixed on the top of the trolley body 1, and two elastic clips 61 are fixed on the top of the fixing rod 6 in parallel. A plugging assembly 7 for cleaning the grouting hose 33 after use is provided on the top of the trolley body 1. The plugging assembly 7 includes a plugging rod 71 that is engaged with the elastic clip 61, a plurality of annular air bags 72 that are sleeved and fixed on the plugging rod 71, and a soft connecting pipe 73 for connecting adjacent annular air bags 72, wherein an air filling pipe 721 is fixed and connected to one of the annular air bags 72, and a sealing plug 8 that is engaged with the air filling pipe 721 is provided at the end of the air filling pipe 721. The distance between adjacent slurry outlet holes 331 in the axial direction of the grouting hose 33 is equal to the distance between adjacent annular air bags 72.

[0056] When the annular airbag 72 is not inflated, the outer diameter of the annular airbag 72 is smaller than the inner diameter of the grouting hose 33, so that the staff can insert the blocking rod 71 into the grouting hose 33 and clean the inside of the grouting hose 33 by pulling the blocking rod 71. After the sealing plug 8 is opened and the annular airbag 72 is inflated through the inflation tube 721, due to the setting of the soft connecting tube 73, multiple annular airbags 72 are bulged, so that the grouting hoses 33 at all the slurry outlet holes 331 are expanded, and the diameter of the side of the slurry outlet hole 331 away from the blocking rod 71 is close to the diameter of the side of the blocking rod 71, so that it is convenient for the staff to use the annular brush matched with the grouting hose 33 to clean the residual materials in the slurry outlet hole 331, which is conducive to the normal use of the grouting hose 33 next time.

[0057] A rubber ring 9 is sleeved on the blocking rod 71, and the inner diameter of the rubber ring 9 is smaller than the outer diameter of the annular airbag 72 when it is not inflated. A fixing ring 91 is attached to and fixed on the outer wall of the rubber ring 9, and a plurality of anti-slip convex strips 92 are evenly fixed on the outer wall of the fixing ring 91. A spiral groove 93 is provided on the inner wall of the rubber ring 9. The provision of the rubber ring 9 and the spiral groove 93 facilitates the staff to clean the sundries contaminated on the outer side of the annular airbag 72 by pushing the fixing ring 91.

[0058] The working principle of a floor hollow repair construction method in the present embodiment is: insert the suction hose 22 into the hollow through the drilled hole, and the vacuum cleaner 21 can clean the dust and other debris in the hollow through the suction hose 22 after working. Since the angle between the center of the hollow area and the connecting line between the two holes is 90 degrees, although the suction hose 22 is a hose, it still has a certain hardness. The suction hose 22 entering the hollow from the two drilled holes has extension directions that are basically perpendicular to each other. Such a setting can improve the cleaning effect of dust and other debris in the hollow.

[0059] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
