Description

Technical Field

[0001] The invention relates to the technical field of construction of working layer voids, in particular to a construction method capable of eliminating working layer voids at joints. Background Art

[0002] Splicing technology is widely used in many fields such as construction, machinery manufacturing, decoration and renovation. However, the problem of voids in the working layer at the joints has always plagued the improvement of project quality. These voids may lead to many adverse consequences such as reduced structural strength, decreased waterproof performance, and appearance defects. Therefore, improving the construction method to eliminate the voids in the working layer at the joints has extremely important practical value.

[0003] The existing method of detecting voids in floors is for workers to use a soft rubber hammer to knock on the floor to produce a sound for judgment. When faced with some smaller and shallower voids, the sound produced by this method changes little, making it difficult to judge. Therefore, a construction method that can eliminate voids in the working layer at the joint is proposed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a construction method that can eliminate voids in the working layer at the joint, thereby solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A construction method capable of eliminating voids in the working layer at the joint, comprising the following steps:

[0006] S1. Inspection and base treatment: Inspect the base at the joint, remove dust, oil, loose materials and other impurities on the surface of the base at the joint, and level the uneven base;

[0007] S2. Floor splicing: When the working layer is spliced, it is spliced ​​by using mortise and tenon structure;

[0008] S3, pre-fixation: After the wooden floor is spliced, the wooden floor is pre-fixed by firing air nails with a pneumatic nail gun;

[0009] S4, filling treatment: using filling materials, and filling the filling materials evenly into the joint gaps through a mixing filling device;

[0010] S5. Compacting treatment: After the filling material is filled, compaction equipment is used to compact it so that the filling material and the splicing material are tightly combined;

[0011] S6. Appearance inspection: Check whether there are gaps or unevenness at the joints, observe whether the filling material is full and the surface is smooth, etc.

[0012] According to the above technical solution, an inspection device is provided in S1, and an infrared level is installed under the inspection device. The inspection device is used to operate when inspecting the base layer at the joint in S1. An infrared level is fixedly installed under the inspection device, and a camera is provided at the bottom of the inspection device. A cache module is provided inside the camera, and the camera is electrically connected to the cache module. The inspection device uses mobile phone Bluetooth as a transmission medium, and the cache data attribute in the inspection device is overwriteable. By setting the infrared level, the base layer ground is inspected and the inspection result is sent to the mobile phone, so that the staff can lay moisture-proof mats according to the orientation on the mobile phone, and then level the ground with cement to ensure that the flatness of the ground reaches the standard of no more than 2mm height difference within every 2 meters, avoiding the situation of height difference in the base layer, which makes the splicing materials unable to fit tightly during the installation process, so that after the wooden floor is laid, it is easy to be suspended in uneven parts, thereby forming voids.

[0013] According to the above technical solution, when cleaning the surface of the base layer in S1, the detergent is diluted in a 1:1 ratio and then stirred, and a high-pressure water gun is used during the cleaning process. The water inlet of the high-pressure water gun is fixedly connected to the stirred detergent container through a three-way pipe. At the same time, when cleaning the surface of the base layer in S1, a manual long-pole cleaning brush is also included, and the base floor is cleaned to ensure that the surface of the base layer is clean and tidy, and impurities on the surface of the base layer are avoided. Impurities block the good contact between the splicing material and the base layer, and the dust on the base layer will prevent the wood glue from fully bonding to the base layer. When the wooden floor is affected by external force or environmental changes, voids are easily generated.

[0014] According to the above technical solution, the left and right edges of the wooden floor in S2 are respectively provided with tenons and grooves, and the splicing is completed by inserting the tenons of one wooden floor into the grooves of another wooden floor. The splicing is done through the mortise and tenon structure, which has good tightness and a relatively simple and direct installation process, so that operators can quickly get started. Moreover, the floor is very stable after splicing, and is not prone to displacement, warping, etc., and has high stability. The moisture content of the wooden floor can be controlled between 10% and 12%. If the moisture content of the wooden floor is higher than 10% and 12%, it is easy to expand, thereby changing the original structure of the splicing, making the splicing gap larger, and after the humidity is reduced and the wood shrinks, it will leave a cavity at the splicing, thereby affecting the structural strength, waterproof performance, appearance, etc.

[0015] According to the above technical solution, the pneumatic nail gun in S3 uses pneumatic nails with a nail length of 15-25 mm. By using these pneumatic nails, the pneumatic nails can better fix the floor. At the same time, the smaller the pneumatic nail head is, the less damage to the floor surface is caused, and the pneumatic nails are prevented from penetrating the floor surface. During the pre-fixing period, these pneumatic nails can prevent the floor from moving.

[0016] According to the above technical solution, the mixing and filling device used in S4 includes a mixing drum and a filling rack, wherein the filling rack is arranged at the bottom of the mixing drum, and an anti-sinking structure is arranged inside the mixing drum. Through the setting of the anti-sinking structure, the wood chips and the filling material are mixed more evenly, and the phenomenon of crusting and sinking to the bottom is not easy to occur. A scraper is fixedly installed inside the filling rack through a transmission structure, and the mixture of wood chips and filling materials discharged from the mixing drum is evenly filled into the gap through the scraper, thereby improving the efficiency of mixing and filling.

[0017] According to the above technical scheme, the compaction equipment used in S5 includes an adjustable pressure roller and a pushing frame for pushing the adjustable pressure roller, the adjustable pressure roller is provided with a counterweight chamber inside, so that the staff can adjust the weight of the pressure roller according to different template materials to improve the compaction efficiency, and the pushing frame is provided with a vibration assembly inside, the vibration assembly includes a vibration motor fixedly mounted on the inner wall of the pushing frame and a transmission member fixedly mounted on the output end of the vibration motor, the transmission member is in contact with the adjustable pressure roller, so that when the adjustable pressure roller performs compaction operation, the amplitude generated by the vibration assembly has a small vibration and promotion effect on the compaction operation of the adjustable pressure roller.

[0018] According to the above technical solution, after the material in S4 is filled, a trimming device is used to trim the surface of the splicing gap. The trimming device includes a movable frame with universal wheels, and the bottom of the movable frame is movably connected with a trimming plate through a bonding component. The bonding component includes an elastic member and a connecting member. The elastic member and the connecting member are arranged to ensure the vertical setting of the trimming plate, and the movable frame with universal wheels is used to push the correction plate to the target position to perform trimming work on the surface of the splicing gap.

[0019] According to the above technical solution, S61, the gap spacing at the joint is less than 1mm, and the surface of the joint is smooth and flat, which meets the qualified acceptance standard;

[0020] S62, if the gap spacing at the joint is greater than 1mm, but the surface of the joint is smooth and flat, it does not meet the qualified acceptance standard and the secondary processing procedure is started;

[0021] S621, take out the wooden floor with a larger gap between the joints, and execute step S2 again;

[0022] S63, if the gap spacing at the joint is less than 1mm, but the surface of the joint is not smooth and flat, it does not meet the qualified acceptance standards. Start the secondary processing procedure and execute the S4 step again to make the process more concise and efficient, so that the staff can quickly check and reduce omissions.

[0023] According to the above technical solution, the S6 infrared thermal imaging detection equipment is operated, and the infrared thermal imaging detection equipment uses the mobile phone Bluetooth as a transmission medium. By setting the infrared thermal imaging detection equipment, the floor can be detected by infrared thermal imaging, and the presence of a cavity underneath can be determined by judging the difference in the temperature display of the floor. The infrared thermal imaging detection equipment uses the mobile phone Bluetooth as a transmission medium, and the infrared thermal imaging detection equipment can be moved through the operation interface of the mobile phone, so that the infrared thermal imaging detection equipment can detect every corner of the wooden floor. Through multi-angle detection, the detection effect is more accurate, and at the same time, the situation of misjudgment is avoided, and the situation of operators lifting up the normal wooden floor is reduced, thereby ensuring the quality of work.

[0024] The present invention provides a construction method that can eliminate voids in the working layer at the joint. It has the following beneficial effects:

[0025] (1) A construction method that can eliminate voids in the working layer at the joint. By setting up infrared thermal imaging detection equipment, the floor can be detected by infrared thermal imaging. By judging the difference in the temperature display of the floor, it is determined whether there is a void underneath. The infrared thermal imaging detection equipment uses the mobile phone Bluetooth as a transmission medium. The infrared thermal imaging detection equipment can be moved through the mobile phone's operating interface, so that the infrared thermal imaging detection equipment can detect every corner of the wooden floor. Through multi-angle detection, the detection effect is more accurate, and at the same time, it avoids misjudgment and reduces the occurrence of operators lifting up the normal wooden floor, thereby ensuring the quality of work.

[0026] (2) A construction method that can eliminate voids in the working layer at the joint. The base floor is inspected by inspection equipment to observe whether there are impurities such as dust, oil, loose materials, etc. on the surface of the base floor, and the base floor is cleaned to ensure that the surface of the base floor is clean and tidy, and to avoid impurities on the surface of the base floor. Impurities block the good contact between the splicing materials and the base floor, and the dust on the base floor will prevent the wood glue from fully bonding with the base floor. When the wooden floor is affected by external forces or environmental changes, voids are easily generated. The base floor is inspected by an infrared level meter installed under the inspection equipment, and the inspection results are sent to a mobile phone, so that the staff can lay moisture-proof mats according to the orientation on the mobile phone, and then use cement to level the ground to ensure that the ground flatness meets the standard of no more than 2 mm height difference within every 2 meters, avoiding the situation where there is a height difference in the base floor, which causes the splicing materials to be unable to fit tightly during the installation process, so that after the wooden floor is laid, it is easy to be suspended in uneven parts, thus forming voids.

[0027] (3) A construction method that can eliminate voids in the working layer at the joints. The method is to mix the sawdust and filling material evenly, use a filling tool such as a putty knife, and evenly apply the filling material to the gaps in the floor, so that the filling material can fully enter the gaps, and allow it to dry and fix. The filling material is evenly filled into the joint gaps, and the gaps are fully filled with the filling material to avoid the situation in which, in some narrow gaps, the filling material is too thick, it is difficult to completely fill the gaps, leaving voids and affecting the waterproof effect of the floor. At the same time, ensure that the filling material does not shrink after curing, thereby avoiding the formation of voids. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 2 It is a detailed structural diagram of the process of the present invention. DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 2 One embodiment of the present invention is: a construction method for eliminating voids in the working layer at the joint, comprising the following steps:

[0032] S1. Inspection and base treatment: Inspect the base at the joint, remove dust, oil, loose materials and other impurities on the surface of the base at the joint, and level the uneven base;

[0033] S2. Floor splicing: When the working layer is spliced, it is spliced ​​by using mortise and tenon structure;

[0034] S3, pre-fixation: After the wooden floor is spliced, the wooden floor is pre-fixed by firing air nails with a pneumatic nail gun;

[0035] S4, filling treatment: using filling materials, and filling the filling materials evenly into the joint gaps through a mixing filling device;

[0036] S5. Compacting treatment: After the filling material is filled, compaction equipment is used to compact it so that the filling material and the splicing material are tightly combined;

[0037] S6. Appearance inspection: Check whether there are gaps or unevenness at the joints, and observe whether the filling material is full and the surface is smooth.

[0038] In one embodiment of the present invention, an inspection device is provided in S1, and an infrared level is installed under the inspection device. When S1 inspects the base layer at the joint, the inspection device is operated. An infrared level is fixedly installed under the inspection device, and a camera is provided at the bottom of the inspection device. A cache module is provided inside the camera, and the camera is electrically connected to the cache module. The inspection device uses mobile phone Bluetooth as a transmission medium, and the cache data attribute in the inspection device is overwriteable. By setting the infrared level, the base layer ground is inspected and the inspection result is sent to the mobile phone, so that the staff can lay moisture-proof mats according to the orientation on the mobile phone, and then level the ground with cement to ensure that the flatness of the ground reaches the standard of no more than 2mm height difference within every 2 meters, thereby avoiding the base layer. There is a height difference, which makes it impossible for the splicing materials to fit tightly during the installation process, so that after the wooden floor is laid, it is easy to be suspended in uneven places, thus forming voids. When cleaning the surface of the base layer in S1, the detergent is diluted in a 1:1 ratio and stirred, and a high-pressure water gun is used during the cleaning process. The water inlet of the high-pressure water gun is fixedly connected to the stirred detergent container through a three-way pipe. At the same time, when cleaning the surface of the base layer in S1, a manual long-pole cleaning brush is also included, and the base floor is cleaned to ensure that the surface of the base layer is clean and tidy, and impurities on the surface of the base layer are avoided. Impurities block the good contact between the splicing material and the base layer, and the dust on the base layer will prevent the wood glue from fully bonding to the base layer. When the wooden floor is affected by external forces or environmental changes, voids are easily generated.

[0039] In addition, the left and right edges of the wooden floor in S2 are respectively provided with convex tenons and grooves. The convex tenon of one wooden floor is inserted into the groove of another wooden floor to complete the splicing. The splicing is done through the mortise and tenon structure. This method has good tightness and the installation process is relatively simple and direct, so that the operator can quickly get started. Moreover, the floor is very stable after splicing, and it is not easy to shift or warp. The stability is high, and the moisture content of the wooden floor can be controlled between 10% and 12%. If the moisture content of the wooden floor is higher than 10% and 12%, it is easy to expand, thereby changing the original structure of the splicing, making the splicing gap larger, and after the humidity is reduced, the wood shrinks, and it will expand at the splicing. Leaving holes, which will affect the structural strength, waterproof performance, appearance, etc. The pneumatic nail gun in S3 uses air nails with a nail length of 15-25mm. By using this air nail, the air nails can better fix the floor. At the same time, the smaller the air nail head is, the less damage to the floor surface is caused, and the air nails are prevented from penetrating the floor surface. The air nails are driven into the edge of the spliced ​​wooden floor every 30-50cm with a nail gun. The air nails should be driven in obliquely at an angle of about 30-45 degrees, so that the air nails can better fix the floor. During the pre-fixing period, these air nails can prevent the floor from moving. After the floor is fully installed, the nail holes are filled with special filling materials to make the floor more secure.

[0040] In the embodiment of the present invention, when filling the wooden floor, it is necessary to ensure that the indoor temperature remains stable to avoid large temperature fluctuations that may affect the performance of the splicing material and the filling material. In S4, the sawdust and the filling material are evenly mixed, and a filling tool such as a putty knife is used to evenly apply the filling material to the gaps in the floor so that the filling material fully enters the gaps. In this way, it is avoided that in some narrow gaps, if the filling material is too thick, it is difficult to completely fill the gaps, leaving voids and affecting the waterproof effect of the floor. At the same time, it is ensured that the filling material does not shrink after curing, thereby avoiding the formation of voids. During the floor construction and after the wooden floor is spliced, use a rubber hammer to gently tap the wooden floor to make the wooden floor fit better with the glue layer and expel the air to avoid gas residue between the wooden floor and the glue layer, which will cause voids after the glue layer solidifies. For the gaps in the wooden floor, a mildew-proof and waterproof caulking agent is used to fill them. When filling, use a glue gun to evenly inject the caulking agent into the gaps, and then use a special caulking ball to compact the caulking agent along the gaps to allow the caulking agent to fully fill the gaps. After curing, the surface is smooth and flat, which effectively eliminates the voids at the joints and avoids problems such as hollow tiles and falling off of caulking agent after long-term use.

[0041] In addition, the compaction equipment used in S5 includes an adjustable pressure roller and a pushing frame for pushing the adjustable pressure roller. A counterweight cavity is arranged inside the adjustable pressure roller, so that the staff can adjust the weight of the pressure roller according to different template materials, improve the compaction efficiency, and make the filling material and the splicing material closely combined, so as to avoid insufficient pressure, so that the filling material cannot be fully filled in the gap, thereby forming a void in the insufficiently filled place, and resulting in limited fitting effect of the filling material and the splicing material. A vibration component is arranged inside the pushing frame, and the vibration component includes a vibration motor fixedly installed on the inner wall of the pushing frame and a transmission fixedly installed at the output end of the vibration motor. The transmission member is in contact with the adjustable pressure roller, so that when the adjustable pressure roller is performing compaction operation, the amplitude generated by the vibration component has a small vibration and promotion effect on the compaction operation of the adjustable pressure roller. After the material in S4 is filled, a trimming device is used to perform a trimming operation on the surface of the splicing gap. The trimming device includes a moving frame with universal wheels, and the bottom of the moving frame is movably connected to a trimming plate through a fitting component. The fitting component includes an elastic member and a connecting member. The elastic member and the connecting member are arranged to ensure the vertical arrangement of the trimming plate, and the moving frame with universal wheels is used to push the correction plate to the target position to perform the trimming work on the surface of the splicing gap.

[0042] In the present invention, if the gap spacing at the joint is less than 1 mm and the surface of the joint is smooth and flat, the qualified acceptance standard is met;

[0043] S62, if the gap spacing at the joint is greater than 1mm, but the surface of the joint is smooth and flat, it does not meet the qualified acceptance standard and the secondary processing procedure is started;

[0044] S621, take out the wooden floor with a larger gap between the joints, and execute step S2 again;

[0045] S63. If the gap spacing at the joint is less than 1mm, but the surface of the joint is not smooth and flat, it does not meet the qualified acceptance standards. Start the secondary processing procedure and execute S4 step again to make the process more concise and efficient, so that the staff can quickly check and reduce omissions. S6 infrared thermal imaging detection equipment is operated. The infrared thermal imaging detection equipment uses the mobile phone Bluetooth as the transmission medium. By setting the infrared thermal imaging detection equipment, it can detect the floor through infrared thermal imaging. By judging the difference in the temperature display of the floor, it is determined whether there is a cavity underneath. The infrared thermal imaging detection equipment uses the mobile phone Bluetooth as the transmission medium. The infrared thermal imaging detection equipment can be moved through the mobile phone's operation interface, so that the infrared thermal imaging detection equipment can detect every corner of the wooden floor. Through multi-angle detection, the detection effect is more accurate, and at the same time, it avoids the situation of misjudgment and reduces the situation of operators lifting the normal wooden floor, thereby ensuring the quality of work.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
