Description

Technical Field

[0001] The invention relates to the technical field of special floor slabs in which pipelines are laid, and in particular to a grouting micro-lifting floor slab frame air conditioning leveling system and its application and construction method. Background Art

[0002] The flatness of the ground is the focus of interior decoration. Whether it is a residence or an industrial plant, the flatness of the ground is an important part. For residences, uneven ground is not only unsightly, but also brings serious difficulties to the installation of floors and home appliances. For factories, many precision equipment requires that the components be placed horizontally during installation. If they are tilted, they cannot be used normally.

[0003] For ground leveling, the most favorable time is during the construction of a structure (main structure). In this process, since no new structure is added, there is no need to consider the connection between the new structure and the original main structure, which can ensure sufficient bearing capacity, without considering the reliability of the connection, and does not take up additional space. The most critical step is the leveling of concrete, which is detected by testing instruments such as spirit levels and spirit levels, and leveled with tools such as scrapers, scraper bars, and trowels. In theory, laser leveling instruments can also be used for concrete leveling (laser lines are used as a reference for leveling), but in actual operation, they are often not applicable because if used for concrete leveling, there are too many points that need to be measured and controlled and they are too low. The concrete laser leveling machine has a built-in laser leveling instrument, which uses a series of supporting servo machinery to achieve this, but these supporting servo machinery are too large after adding one piece, which is completely unsuitable for most conventional residences. They can only be driven into a ground venue for construction or used in outdoor open occasions.

[0004] If the leveling is not completed in the primary structure, it is necessary to re-level it in the secondary structure. The most common practice is to spread a new leveling layer (usually cement mortar) on the primary structure for leveling. Due to the different ages and grades of concrete, a bonding layer must be set between the leveling layer and the original main structure, and the leveling layer itself must be thick enough, generally more than two centimeters (if the mortar is too thin, it will collapse, and even if it does not collapse, it cannot be firmly combined with the main structure). The newly added bonding layer and leveling layer occupy a certain floor height. At the same time, because it adds a lot of load to the main structure (a house requires several tons of mortar for leveling), the remaining available bearing capacity of the floor slab is reduced, affecting the use of housing. Cement / gypsum self-leveling is similar to conventional cement mortar leveling. The advantage is that it can achieve a smoother effect, but the cost is also higher. Another approach is epoxy self-leveling, but epoxy self-leveling has special requirements for the main structure itself, and the cost is also high. Most residential users do not need such a high degree of flatness, so it is mainly used in factory buildings.

[0005] The above operations are collectively referred to as wet work in the construction field. There are common problems of wet work, such as pollution to the site, delamination from the original floor surface, hollowing and cracking; leveling is difficult, a lot of manpower is consumed, and the overall cost is high.

[0006] In addition to the above leveling measures, there is another uncommon leveling measure, which is the so-called elevated floor. A stainless steel support frame or a resin support frame (the support frame structure is two screwed sleeves, adjacent support frames are connected by beams, and a buffer strip is set on the top of the support frame) is used to support a new floor panel on the original base. This practice seriously reduces the bearing capacity of the ground and seriously squeezes the floor height. The advantage is that the floor has a good anti-static effect, and a large number of water and electricity pipelines can be laid in the elevated layer. Therefore, it is mainly used in places such as large computer rooms where there are many pipelines and anti-static requirements. As for the leveling effect, it is achieved by the way, not the main purpose of using this structure.

[0007] For the raised floor, the height of its support frame should ideally be adjusted before the structural board is laid, but this is not the case in practice. After the height of the support frame is adjusted and the structural board is laid on it, the height of the support frame needs to be fine-tuned for each board laid, because even if the top height of each support frame is consistent, it will become uneven after the structural board is laid. In order to meet the requirement that people can reach under the board to adjust the height after laying the board, the height of the raised floor is much higher than actually needed, and the cross-section of the support frame cannot be too large. This limits the increase in bearing capacity and seriously squeezes the floor height.

[0008] The inventors found that there are three reasons why the leveled support frame becomes uneven again after the structural board is laid. First, there is a random-sized clearance in the thread, which allows the support frame to be compressed downward for a certain distance after the support frame is under pressure; second, there is a random-sized clearance between the sleeves, which causes a random angle between the two sleeves during the expansion and contraction of the support frame; third, the stiffness of the resin / stainless steel sleeve is relatively low, and there is a certain deformation after being compressed. Summary of the invention

[0009] The invention provides a grouting micro-lifting floor panel frame air conditioning leveling system and an application and a construction method thereof.

[0010] The technical problem to be solved is: during the interior decoration process, if a leveling layer is used for leveling, the ground bearing capacity will be squeezed; if an elevated floor is used for leveling, the ground bearing capacity will be reduced and the floor height will be seriously squeezed.

[0011] In order to solve the above technical problems, the present invention adopts the following technical solutions: a grouting micro-lifting floor panel air conditioning and leveling system, which is arranged on the original floor panel and used for secondary structure construction, wherein the secondary structure construction includes interior decoration, and the original floor panel includes the floor of the basement, the floor of the first floor and the floor slabs above the first floor. The air conditioning and leveling system includes a plurality of levelers evenly distributed on the original floor panel, and the new floor panel is spread on the leveler, and the leveler is fixedly connected to the original floor panel and the new floor panel respectively; The leveler is a round flat box with a box cover and a box body screwed together, and the leveler is filled with a grouting stone body formed by solidifying a self-compacting grouting material; The diameter of the box body is not less than the short dimension of the largest pit that must be produced under the original floor panel construction process, and the sum of the height of the box cover and the height of the box body does not exceed the radius of the box body; The upper surface of the box cover has an edge without rounded corners or chamfers, which is recorded as a laser reference edge. The laser reference edges of each leveler intersect with the same horizontal beam of the laser leveler. The self-compacting grouting material is a mortar without shrinkage, coarse aggregate and powder, and the aggregate particles of the fine aggregate in the self-compacting grouting material have no pores.

[0012] Furthermore, according to the different construction techniques of the original floor slab, the short-direction dimension of the largest pit that is bound to be produced is calculated in the following way: If the original floor slab is a cast-in-place slab, the short dimension of the largest pit that will inevitably be produced is the width of the formwork joint of the cast-in-place slab; If the original floor slab is a composite slab, the maximum pit that is bound to be produced is deemed to be non-existent, and the diameter of the box body is smaller than the width of the joint between the composite slabs; If the original floor slab is a precast slab with a leveling layer, the short dimension of the largest pit that will inevitably be produced is the width of the widest trowel used in the leveling process.

[0013] Furthermore, the leveler is glued to the original floor panel and the new floor panel respectively, and ribs are provided on the top and bottom of the leveler for facilitating gluing, wherein the ribs on the box cover are made of transparent material and are recorded as laser display ribs; during the height adjustment process of the leveler, the laser display ribs intersect with the light beam of the laser leveler from bottom to top and display the position of the light beam.

[0014] Furthermore, the inner side elevation of the box body is provided with a thread, the outer side elevation of the box cover is provided with a thread, and the box cover is inserted downward into the box body; a pressure relief grouting hole for grouting and pressure relief is provided at the center of the top of the box cover, and the laser display rib is a concentric circle arranged around the pressure relief grouting hole; The original floor panels are coated with a primer for resisting alkali and preventing the original floor panels from falling off.

[0015] Furthermore, the self-compacting grouting material is a mortar made of quartz sand as aggregate and white cement as gelling agent, the 3-hour free water seepage rate of the mortar is not more than 1%, and the seepage water should be completely absorbed by the mortar within 24 hours.

[0016] The invention discloses an application of a grouting micro-lifting floor panel frame air conditioning leveling system, which uses the above-mentioned grouting micro-lifting floor panel frame air conditioning leveling system to create a flat overhead floor panel on an uneven original floor panel, and lay water and electricity pipelines under the new floor panel.

[0017] A construction method of a grouting micro-lifting floor panel frame air conditioning flat system is used for the construction of the above-mentioned grouting micro-lifting floor panel frame air conditioning flat system, and comprises the following steps: Step 1: Apply primer to the original floor slab; Step 2: Lay water and electricity pipelines on the original floor slab; Step 3: Use MS structural adhesive to stick the leveler to the ground; Step 4: Rotate the box cover to adjust the height of the leveler so that the laser reference edge of each leveler intersects with the same horizontal beam of the laser leveler, and then fill each leveler with self-compacting grouting material; Step 5: After the self-compacting grouting material is completely cured, apply MS structural glue on the leveler and lay the new floor slab; Step 6: Fill the joints of the new floor panels with seam glue to seal them.

[0018] Compared with the prior art, the grouting micro-lifting floor panel frame air conditioning leveling system and its application and construction method of the present invention have the following beneficial effects: In the present invention, a grouted round flat box is used to prop up a new floor panel to create an elevated floor. The round flat box itself can stand stably, and the force is mainly dependent on the grouted stone body inside, without the need for crossbeams and buffer rubber strips (the box cover and the box body themselves play the role of buffer rubber strips), thereby simplifying the installation, and the box cover and the box body are not prone to causing an angle (that is, the box cover is crooked) during the lifting process due to the horizontal clearance; and because of the simple and symmetrical appearance, it is easy to use a laser leveler to make the top heights of each box cover consistent (the crossbeams and buffer rubber strips in the support frame in the prior art interfere with the light beam) After grouting and curing, the vertical play between the threads, the horizontal play between the box cover and the box body (all movable spaces including all play are filled with grouting materials and will not be deformed due to loading), and the deformation caused by vertical loads (the deformation of concrete after compression can be basically ignored, and it is regarded as a rigid structure in architecture, while steel and plastic are regarded as flexible structures) will no longer affect the height of the round flat box, so you can safely and boldly lay the structural slab on it without the need for secondary fine-tuning of the height, and there is no need to leave enough space under the structural slab to put your hands in. This reduces the occupation of the floor height, and at the same time, the bearing capacity of the entire structure is much stronger than the existing overhead floor (the round flat box does not need to consider putting your hands in to fine-tune the height afterwards, so the cross-section can be made so large that it cannot be operated with one hand).

DETAILED DESCRIPTION

[0020] like Figure 6-7 As shown, a grouting micro-lifting floor panel air conditioning flat system is arranged on the original floor panel 1 and is used for secondary structure construction. The secondary structure construction includes interior decoration. The original floor panel 1 includes the floor of the basement, the floor of the first floor and the floor of the floors above the first floor. The floor panels here originally include all the floors that need to be leveled. Of course, in addition to these indoor original floor panels 1, they can also be used outdoors, but there is rarely a need for decoration outdoors.

[0021] The air conditioning leveling system includes a plurality of levelers 5 evenly distributed on the original floor panel 1, a new floor panel 7 is spread on the levelers 5, and the levelers 5 are fixedly connected to the original floor panel 1 and the new floor panel 7 respectively; Since the leveler 5 in the present invention will not overturn itself, it can be fixed by gluing without installing a crossbeam.

[0022] The leveler 5 is a round flat box with a box cover 51 and a box body 52 screwed together, and the leveler 5 is filled with a grouting stone body 6 formed by solidifying a self-compacting grouting material; The grouting stone body 6 has multiple functions. In addition to the main load-bearing function, it also plays the role of fixing the height of the leveler 5. The height of the support frame of the overhead floor in the prior art is not well maintained. Even if the top height is adjusted to be consistent before installing the structural board (corresponding to the new floor board 7 in the present invention), it is easy to become uneven after installing the structural board, and it is necessary to reach under the structural board to make fine adjustments again.

[0023] The diameter of the box body 52 is not less than the short dimension of the largest pit that must be produced under the construction process of the original floor panel 1, and the sum of the height of the box cover 51 and the height of the box body 52 does not exceed the radius of the box body 52; Based on the existing floor construction technology, there will not necessarily be bulges on the surface, and even if there are bulges, they are usually small (a few coarse aggregate particles). However, almost all floor slabs will inevitably have pits. For example, during the pouring process, concrete often leaks out from the template joints, resulting in dents on the floor surface. Or when using a trowel to apply plaster, the local force is slightly too strong.

[0024] Different from conventional overhead floors, the original floor panel 1 in the present invention is not subjected to preliminary leveling treatment, and the leveler 5 is directly installed on the original floor panel 1. Therefore, the leveler 5 here must consider the situation when a pit appears at the installation position. The line segment with both end points on the edge line of the pit is recorded as the pit segment, and the longest pit segment is recorded as the long-direction line. Among the pit segments perpendicular to the long-direction line, the length of the longest pit segment is counted as the short-direction dimension. The diameter of the box body 52 is not less than the short-direction dimension of the largest pit that must be produced under the construction process of the original floor panel 1, so that it can be set across these pits. The sum of the height of the box cover 51 and the height of the box body 52 does not exceed the radius of the box body 52, that is, even if the leveler 5 is adjusted to the highest, its height does not exceed half of the diameter, ensuring that it will not overturn.

[0025] like Figure 8 As shown, the upper surface of the box cover 51 has a circle of edges without rounded corners or chamfers, and is recorded as a laser reference edge 54. The laser reference edge 54 of each leveler 5 intersects with the same horizontal beam of the laser leveler; The support frame of a conventional raised floor has a series of accessory components including beams and buffer strips on its surface, which interfere with the use of a laser leveler for leveling. The leveler 5 in the present invention does not require these, so a laser reference edge 54 similar to a scale line can be provided.

[0026] The self-compacting grouting material is a mortar without shrinkage, without coarse aggregate and powder (powdered aggregate), and the aggregate particles of the fine aggregate in the self-compacting grouting material have no pores.

[0027] If the self-compacting grouting material shrinks during the solidification process, it will not be able to fix the height of the leveler 5. The reason for using self-compacting grouting material is that the construction site of the present invention is not suitable for pressurization or vibration. Self-compacting grouting material should not contain coarse aggregate and powder. The self-compacting grouting material has strong fluidity. Coarse aggregate and powder are easy to cause local unevenness during grouting and solidification, which may cause the box cover 51 to fall off due to slurry solidification or thermal expansion and contraction. The influence of coarse aggregate is particularly obvious. At the same time, aggregate particles cannot have pores. Aggregate particles with pores may introduce air and are more likely to be crushed, thereby affecting the bearing capacity.

[0028] The self-compacting grouting material is allowed to expand during the curing process because the pressure relief grouting hole 53 is not blocked during the entire installation process. When expanding, part of the self-compacting grouting material can overflow along the pressure relief grouting hole 53 without damaging the leveler 5 or tilting the box cover 51.

[0029] According to the different construction techniques of the original floor panel 1, the short-direction dimension of the largest pit that will inevitably be produced is calculated in the following way: If the original floor panel 1 is a cast-in-place floor panel, the short dimension of the largest pit that will inevitably be produced is the width of the template joint of the cast-in-place floor panel; There are some wooden formworks at the bottom of the cast-in-place floor, and there are joints in the middle of these formworks. It is impossible to completely seal the joints, and there will always be some leakage of concrete liquid at some locations, leaving some small pits on the cast-in-place floor above the leakage location. These small pits are very small, usually linear pits with a width of two or three centimeters.

[0030] If the original floor panel 1 is a laminated panel, the maximum pit that is bound to be produced is deemed to be non-existent, and the diameter of the box body 52 is smaller than the joint width between the laminated panels; The width of the joints between the composite slabs is extremely wide, because the joints of the composite slabs are actually equivalent to post-cast strips, which play the role of connecting the composite slabs as a whole. With such a wide joint, the impact of leaking concrete liquid can be ignored.

[0031] If the original floor panel 1 is a prefabricated panel with a leveling layer, the short dimension of the largest pit that will inevitably be produced is the width of the widest trowel used in the leveling process.

[0032] Trowel is an inevitable tool in the process of concrete leveling. Even if the main part is leveled with a scraper or scraper, the part will still be repaired with a trowel. If a little more force is used during the repair process, pits will be left. Of course, if the trowel is used horizontally and too much force is used, wider pits will be produced, but these wide pits are too obvious and will not be ignored by workers, and will be repaired during leveling. Even if there are wide pits that are missed, the bottom of the pit is relatively flat, allowing the leveler 5 to be placed in the pit without affecting its use.

[0033] As shown in 8-9, the leveler 5 is glued to the original floor panel 1 and the new floor panel 7 respectively, and ribs are provided on the top and bottom of the leveler 5 for facilitating gluing, wherein the ribs on the box cover 51 are made of transparent material and are recorded as laser display ribs 55; during the height adjustment process of the leveler 5, the laser display ribs 55 intersect with the light beam of the laser leveler from bottom to top and display the position of the light beam.

[0034] The main function of the ribs here is to avoid hollowing during the gluing process. The cross-section of the ribs in the present invention is rectangular. By brushing glue on the contact surface, and then moving the leveler 5 or the new floor panel 7, it can fit tightly with the object to be bonded. The laser display ribs 55 on the box cover 51 can also assist in finding the light beam emitted by the laser leveler (it is very conspicuous when the light beam passes through multiple laser display ribs 55). Here, the edges on the top periphery of the outermost circle of laser display ribs 55 can be selected as the laser reference edges 54, or the edges around the top of the box cover 51 can be selected as the laser reference edges 54 without considering the laser display ribs 55. In this embodiment, the box cover 51, the box body 52, and the ribs are all made of transparent hard plastic.

[0035] The inner side of the box body 52 is provided with a thread, and the outer side of the box cover 51 is provided with a thread, and the box cover 51 is inserted downward into the box body 52; a pressure relief grouting hole 53 for grouting and pressure relief is provided at the top center of the box cover 51, and the laser display rib 55 is a concentric circle arranged around the pressure relief grouting hole 53; Since the present invention needs to be like the frequency modulator, some slurry may overflow due to the operator's unstable hands during operation, and if a self-compacting grouting material that expands is used, some slurry will seep out during the solidification process. The seeping slurry not only causes pollution, but also affects the height if the fine aggregate contained in it enters under other levelers 5 being installed. Therefore, the round flat box here is different from the conventional type. The box cover 51 here is smaller than the box body 52 to prevent the slurry from seeping out along the gap between the two. At the same time, the slurry seeping out of the top pressure relief grouting hole 53 will be blocked by the laser display rib 55.

[0036] Accordingly, the ribs at the bottom of the box body 52 may be as follows: Fig. 9 As shown in the figure, the concentric circles with notches can be used to make the adhesive more evenly distributed on the original floor panel 1 by rotating the box body 52 when pasting it on the original floor panel 1 during installation, and when there are small bumps on the original floor panel 1, the small bumps can be located at the notch positions. Of course, if there are larger bumps on the original floor panel 1, they need to be chiseled off or avoided.

[0037] The original floor panel 1 is coated with a primer 2 for alkali resistance and to prevent the original floor panel 1 from falling off. The original floor panel 1 will effloresce and drop concrete slag, thereby affecting the installation of the leveler 5. The primer 2 applied here penetrates into the original floor panel to react with it, strengthens the original floor panel 1, and avoids this problem.

[0038] Self-compacting grouting material is a mortar made of quartz sand as aggregate and white cement as gelling agent. The free water seepage rate of the mortar within 3 hours is not more than 1%, and the seepage water should be completely absorbed by the mortar within 24 hours.

[0039] Here, quartz sand is the fine aggregate that meets the requirements. It has high strength, does not contain powder, and has no pores. Conventional river sand cannot meet the requirements. Conventional river sand contains a considerable amount of powder, many of which have pores, and its strength is lower than that of quartz sand. The reason for controlling the water seepage rate is to avoid affecting the subsequent construction.

[0040] An application of a grouting micro-lifting floor panel frame air conditioning leveling system, using the above-mentioned grouting micro-lifting floor panel frame air conditioning leveling system to create a flat overhead floor panel on the uneven original floor panel 1, and lay water and electricity pipelines 3 under the new floor panel 7.

[0041] That is to say, conventional overhead floors require preliminary leveling of the original floor panels 1, but this is not necessary, and decoration construction can be carried out directly on them, and the whole process is assembled. At the same time, although the space under the new floor panel 7 is not accessible, it is sufficient for the water and electricity pipelines 3.

[0042] like Figure 1-6 As shown, a construction method of a grouting micro-lifting floor panel frame air conditioning flat system is used for the construction of the above-mentioned grouting micro-lifting floor panel frame air conditioning flat system, and includes the following steps: Step 1: Clean the original floor panel 1, and apply primer 2 on the original floor panel 1; Step 2: Laying water and electricity pipelines 3 on the original floor panel 1; Step 3: Use structural adhesive 4 to stick the leveler 5 to the ground; Step 4: Rotate the box cover 51 to adjust the height of the leveler 5 so that the laser reference edge 54 of each leveler 5 intersects with the same horizontal beam of the laser leveler, and then fill each leveler 5 with self-compacting grouting material; Step 5: After the self-compacting grouting material is completely cured, the structural adhesive 4 is applied to the leveler 5 and a new floor panel 7 is laid; the new floor panel 7 can be a cement board, a multi-layer board, an OSB board, etc.; Step 6: Fill the joints of the new floor panels 7 with board seam glue 8 for sealing. Here, the board seam glue 8 can also be made of MS structural glue 4.

[0043] The embodiments described above are merely descriptions of preferred implementation modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
