A grouting micro-lifting floor panel frame air conditioning flat system and its application and construction method

Abstract

The present invention relates to the technical field of special floor slabs in which pipelines are laid, and discloses a grouting micro-lifting floor panel air conditioning leveling system and its application and construction method. In the present invention, a grouted circular flat box is used to support a new floor panel to create an elevated floor. The circular flat box itself will not overturn, and the force is mainly dependent on the grouting stone body inside. No beams and buffer strips are required, thereby simplifying installation. It is also not easy for an angle to appear between the box cover and the box body during the lifting process due to the horizontal clearance. Moreover, due to the simple and symmetrical appearance, it is easy to use a laser leveler to make the top height of each box cover consistent. After grouting, no matter the vertical clearance between the threads, the horizontal clearance between the box cover and the box body, or the deformation caused by the vertical load, they will no longer affect the height. The structural plate can be directly laid without the need for secondary fine-tuning of the height. There is no need to leave enough space under the structural plate to put hands in, which reduces the occupation of the floor height and significantly improves the bearing capacity.

Description

Technical Field

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

[0002] Floor leveling is a crucial aspect of interior decoration, whether it's a residential building or an industrial plant. In residential buildings, uneven floors are not only unsightly but can also create significant difficulties when installing flooring and appliances. In factories, many precision equipment requires horizontal installation; tilted components will prevent proper operation.

[0003] The most advantageous time to level the ground is during the construction of the primary structure (main structure). Since no new structures are added during this process, there's no need to consider the connection between the new structure and the existing main structure. This ensures sufficient load-bearing capacity and connection reliability, while also minimizing the space required. The most critical step is concrete leveling, which is performed using instruments like spirit levels and levels and tools like scrapers, bars, and trowels. While laser levelers can theoretically be used for concrete leveling (projecting a laser line as a reference for leveling), in practice, this is often impractical because the number of points that need to be measured and controlled is too high and too low. Concrete laser levelers have a built-in laser leveler and utilize a series of supporting servo mechanisms to achieve this. However, these servo mechanisms, when combined, are too bulky to be suitable for most conventional residential buildings. They can only be used on the first floor of a building or in open-air spaces.

[0004] If leveling is not completed in the primary structure, re-leveling is required in the secondary structure. The most common approach is to apply a new screed (usually cement mortar) on top of the primary structure. Due to the different ages and grades of the concrete, a bonding layer is required between the screed and the existing main structure. The screed itself must also be sufficiently thick, generally at least two centimeters. (If the mortar is too thin, it will disintegrate, and even if it doesn't disintegrate, it will not be able to securely bond with the main structure.) The added bonding and screed layers occupy a significant portion of the floor height. Furthermore, because they impose significant loads on the main structure (a single residence can require several tons of mortar for leveling), the remaining available load-bearing capacity of the floor slab is reduced, impacting the usability of the residence. Cement / gypsum self-leveling is similar to conventional cement mortar leveling, with the advantage of achieving a smoother surface, but also at a higher cost. Another alternative is epoxy self-leveling, but this has specific structural requirements and is more expensive. Most residential users don't require such a high level of flatness, so it is primarily used in factories and workshops.

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

[0006] In addition to the aforementioned leveling measures, there's another less common method: the so-called raised floor. Using stainless steel or resin support frames (consisting of two screwed-together sleeves, connected by crossbeams, and topped with rubber cushioning strips), a new floor slab is erected on top of the existing base. This approach significantly reduces the floor's bearing capacity and significantly increases floor height. The advantage is that the floor provides excellent anti-static properties, and the raised floor can accommodate numerous utility lines. Therefore, it's primarily used in applications like large computer rooms where numerous lines are needed and anti-static measures are required. Leveling is a secondary benefit, not the primary purpose of this structure.

[0007] Ideally, the height of the raised floor support frame should be adjusted before the structural slabs are laid, but this isn't always the case. After the support frame height is adjusted and the structural slabs are laid, the height must be fine-tuned with each new slab. Even if the tops of the support frames are aligned, unevenness will occur after the structural slabs are laid. To ensure that the height can be adjusted evenly after the slabs are laid, the raised floor is often much higher than necessary. Furthermore, the cross-section of the support frame cannot be too large. This limits the load-bearing capacity and significantly reduces the floor height.

[0008] The inventors discovered that there are three reasons why the leveled support frame becomes uneven again after laying the structural panels. First, there is a random amount of play in the threads, which allows the support frame to be compressed downward for a certain distance after being under pressure. Second, there is a random amount of play between the sleeves, which creates 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 amount of deformation after being under pressure. Summary of the Invention

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

[0010] The technical problem to be solved is: during interior decoration, 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] To solve the above technical problems, the present invention adopts the following technical solutions: a grouting micro-lift floor panel air conditioning and leveling system is installed on the original floor panel and is used for secondary structure construction, wherein the secondary structure construction includes interior decoration. The original floor panel includes the basement floor, the first floor floor, and the floors of the floors 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 laid on the levelers. The levelers are fixedly connected to the original floor panel and the new floor panel respectively.

[0012] 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;

[0013] 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;

[0014] The upper surface of the box cover has an edge around it without rounded corners or chamfers, which is recorded as a laser reference edge. The laser reference edge of each leveler intersects with the same horizontal beam of the laser leveler.

[0015] 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.

[0016] Furthermore, depending on the original floor slab construction process, the short-side dimension of the largest pit that will inevitably be produced is calculated using the following method:

[0017] 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;

[0018] If the original floor slab is a composite slab, the maximum pit that is bound to be produced is considered non-existent, and the diameter of the box body is smaller than the width of the joint between the composite slabs;

[0019] 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 will be the width of the widest trowel used in the leveling process.

[0020] 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 to facilitate gluing. 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.

[0021] 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;

[0022] The original floor panels are coated with a primer for resisting alkali and preventing the original floor panels from falling off.

[0023] Furthermore, the self-compacting grouting material is a mortar made of quartz sand as aggregate and white cement as gelling agent. The free water exudation rate of the mortar within 3 hours is not more than 1%, and the exuded water should be completely absorbed by the mortar within 24 hours.

[0024] An application of a grouting micro-lifting floor panel rack air-conditioning leveling system, using the above-mentioned grouting micro-lifting floor panel rack air-conditioning leveling system to create a flat overhead floor panel on the uneven original floor panel, and laying water and electricity pipelines under the new floor panel.

[0025] A construction method for a grouting micro-lift floor panel frame air conditioning flat system is used for the construction of the above-mentioned grouting micro-lift floor panel frame air conditioning flat system, and includes the following steps:

[0026] Step 1: Apply primer to the original floor panel;

[0027] Step 2: Lay water and electricity pipelines on the original floor slab;

[0028] Step 3: Use MS structural adhesive to stick the leveler to the ground;

[0029] 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;

[0030] Step 5: After the self-compacting grouting material is completely cured, apply MS structural adhesive on the leveler and lay the new floor slab;

[0031] Step 6: Fill the joints of the new floor panels with seam glue to seal them.

[0032] Compared with the prior art, the grouting micro-lifting floor panel rack air conditioning leveling system and its application and construction method of the present invention have the following beneficial effects:

[0033] In the present invention, a grouted circular flat box is used to support the new floor panel to create an elevated floor. The circular flat box itself can stand stably, and the force is mainly dependent on the grouted stone body inside. No beams or buffer strips are required (the box cover and the box body themselves serve as buffer strips), thereby simplifying installation. The box cover and the box body are also less likely to cause an angle to form during the lifting process due to horizontal clearance (that is, the box cover will tilt). Moreover, due to the simple and symmetrical appearance, it is easy to use a laser leveler to make the top height of each box cover consistent (the beams and buffer strips in the support frame of the prior art interfere with the light beam). After grouting and curing, the vertical play between the threads, the horizontal play between the lid and the body (all movable space, including all play, is filled with grout and will not deform due to loading), and the deformation caused by vertical loads (the deformation of concrete under compression is basically negligible and is considered a rigid structure in architecture, while steel and plastic are considered flexible structures) will no longer affect the height of the circular flat box. This allows for the structural slab to be laid on top without the need for secondary fine-tuning of the height, and there is no need to leave enough space under the structural slab to reach in. This reduces the floor height occupied, and at the same time, the overall structural load-bearing capacity is far greater than that of existing elevated floors (the circular flat box does not require the consideration of reaching 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

[0044] like Figure 6-7 As shown, a grouting micro-lift floor panel air conditioning leveling system is set 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 basement floor, the first floor floor and the floor slabs above the first floor.

[0045] The floor panels here originally include all floors that need to be leveled. Of course, in addition to these indoor original floor panels 1, outdoor can also be used, but outdoor rarely needs to be decorated.

[0046] The air leveling system includes a plurality of levelers 5 evenly distributed on the original floor panel 1, a new floor panel 7 is laid on the levelers 5, and the levelers 5 are fixedly connected to the original floor panel 1 and the new floor panel 7 respectively;

[0047] Since the leveler 5 in the present invention will not overturn itself, it can be fixed by gluing without installing a crossbeam.

[0048] The leveler 5 is a round flat box with a box cover 51 and a box body 52 screwed together. The leveler 5 is filled with a grouting stone body 6 formed by solidifying a self-compacting grouting material.

[0049] The grouting stone body 6 here has multiple functions. In addition to its main load-bearing function, it also serves to fix the height of the leveler 5. The height maintenance of the support frame of the elevated floor in the prior art is not very good. Even if the top height is adjusted to a uniform level before installing the structural plate (corresponding to the new floor plate 7 of the present invention), it is easy to become uneven after the structural plate is installed, and it is necessary to reach under the structural plate to make further fine adjustments.

[0050] 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;

[0051] Based on existing floor slab construction techniques, ridges are unlikely to appear on the surface, and even if they do, they are usually small (a few coarse aggregate particles). However, nearly all floor slabs inevitably have pits. For example, during the pouring process, concrete often leaks through the formwork joints, causing dents on the floor surface. Or, perhaps, a little too much pressure was applied in a certain area with the trowel.

[0052] Unlike conventional elevated 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 location. The line segment with both end points on the pit edge line is recorded as the pit segment, and the longest pit segment is recorded as the long line. Among the pit segments perpendicular to the long line, the length of the longest pit segment is recorded as the short dimension. The diameter of the box body 52 is not less than the short dimension of the largest pit that will inevitably be produced under the construction process of the original floor panel 1, which ensures 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, which means that even after the leveler 5 is adjusted to the highest position, its height does not exceed half of the diameter, ensuring that it will not overturn.

[0053] like Figure 8 As shown, the upper surface of the box cover 51 has a circle of edges without rounded corners or chamfers, which are recorded as laser reference edges 54. The laser reference edges 54 of each leveler 5 intersect with the same horizontal beam of the laser leveler.

[0054] The support frame of a conventional raised floor has a series of auxiliary components including beams and buffer strips on its surface. These auxiliary components 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 set.

[0055] The self-compacting grouting material is a mortar that does not shrink and does not contain coarse aggregate and powder (powdered aggregate), and the aggregate particles of the fine aggregate in the self-compacting grouting material have no pores.

[0056] 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 where the present invention is located is not suitable for pressurization or vibration. Self-compacting grouting material should not contain coarse aggregate and powder. Self-compacting grouting material has strong fluidity. Coarse aggregate and powder are likely to cause local unevenness during grouting and solidification, thereby causing the box cover 51 to become crooked due to solidification of the slurry or thermal expansion and contraction. The influence of coarse aggregate is particularly obvious. At the same time, the aggregate particles cannot have pores. Aggregate particles with pores may introduce air and are more easily crushed, thereby affecting the bearing capacity.

[0057] 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.

[0058] According to the different construction techniques of the original floor panel 1, the short-side dimension of the maximum pit that will inevitably be produced is calculated as follows:

[0059] 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 formwork joint of the cast-in-place floor panel;

[0060] The bottom of the cast-in-place floor is covered with wooden formwork, which has joints between them. It's impossible to completely seal these joints, so concrete will always leak in some places, leaving small pits in the cast-in-place floor above the leaks. These small pits are very small, usually linear pits two or three centimeters wide.

[0061] If the original floor panel 1 is a composite panel, the maximum pit that is necessarily produced is considered to be non-existent, and the diameter of the box body 52 is smaller than the joint width between the composite panels;

[0062] The width of the joints between the composite slabs is extremely wide, because the joints of the composite slabs are actually equivalent to post-pouring strips, which serve to connect the composite slabs as a whole. With such wide joints, the impact of leaking concrete liquid can be ignored.

[0063] 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.

[0064] A trowel is an essential tool during concrete leveling. Even if the main part is leveled with a scraper or blade, some areas will still need to be repaired with a trowel. Applying too much force during repairs can leave indentations. Of course, using the trowel horizontally and applying too much force can create wider indentations, but these wide indentations are too noticeable to be ignored by workers and will be repaired during leveling. Even if a wide indentation is missed, the bottom of the indentation is relatively flat, allowing the leveler 5 to be placed within the indentation without affecting its use.

[0065] As shown in Figures 8-9, the leveler 5 is glued to the original floor panel 1 and the new floor panel 7 respectively. Ribs are provided on the top and bottom of the leveler 5 to facilitate gluing. 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.

[0066] 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 moving the leveler 5 or the new floor panel 7, it can fit tightly with the object to be glued. 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 the 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.

[0067] 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. 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. The laser display rib 55 is a concentric circle arranged around the pressure relief grouting hole 53.

[0068] Because the present invention requires grouting similar to that used in frequency modulators, some slurry may overflow due to unsteady hands during operation. Furthermore, if a self-compacting grouting material that expands is used, some slurry may seep out during the setting process. The seeping slurry not only causes pollution, but also affects the height if the fine aggregate contained in it gets under other levelers 5 being installed. Therefore, the circular flat box here differs from conventional types. The box cover 51 is smaller than the box body 52 to prevent slurry from seeping out through the gap between the two. Furthermore, slurry that seeps out of the pressure relief grouting holes 53 at the top is blocked by the laser display ribs 55.

[0069] Accordingly, the ribs at the bottom of the box body 52 may be as follows: Figure 9 The concentric circles with notches as shown can make it possible to distribute the adhesive more evenly on the original floor panel 1 by rotating the box body 52 when pasting it on the original floor panel 1 during installation, and if there are small bumps on the original floor panel 1, the small bumps can be positioned at the notches. Of course, if there are larger bumps on the original floor panel 1, they need to be chiseled off or avoided.

[0070] The original floor panel 1 is coated with a primer 2 to resist alkali and prevent the original floor panel 1 from falling off. The original floor panel 1 will effloresce and drop concrete debris, which will affect the installation of the leveler 5. The primer 2 applied here penetrates into the original floor panel and reacts with it, strengthening the original floor panel 1 and preventing this problem.

[0071] 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.

[0072] Quartz sand is the fine aggregate required here. It has high strength, is free of fine particles, and is inherently non-porous. Conventional river sand cannot meet this requirement. Conventional river sand contains a considerable amount of fine particles, many of which are porous, and its strength is lower than that of quartz sand. Controlling the bleeding rate is necessary to avoid affecting subsequent construction.

[0073] An application of a grouting micro-lifting floor panel rack air-conditioning leveling system, using the above-mentioned grouting micro-lifting floor panel rack air-conditioning leveling system to create a flat overhead floor panel on the uneven original floor panel 1, and laying water and electricity pipelines 3 under the new floor panel 7.

[0074] That is to say, conventional elevated floors require preliminary leveling of the original floor panel 1, but this does not require that the decoration construction can be carried out directly on it, and the entire process is assembled. At the same time, although the space under the new floor panel 7 is too small to reach, it is sufficient for water and electricity pipelines 3.

[0075] 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:

[0076] Step 1: Clean the original floor panel 1 and apply primer 2 on the original floor panel 1;

[0077] Step 2: Lay water and electricity pipelines 3 on the original floor panel 1;

[0078] Step 3: Use structural adhesive 4 to stick the leveler 5 to the ground;

[0079] 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;

[0080] Step 5: After the self-compacting grouting material is completely cured, apply structural adhesive 4 on the leveler 5 and lay a new floor panel 7; the new floor panel 7 can be a cement board, a multi-layer board, an OSB board, etc.

[0081] Step 6: Fill the joints of the new floor panels 7 with seam glue 8 for sealing. Here, the seam glue 8 can also be made of MS structural glue 4.

[0082] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the 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 fall within the scope of protection determined by the claims of the present invention.
