Description

Technical Field

[0001] The present invention relates to the field of industrialized assembled decoration, and in particular to a dry-process floor heating insulation board and an installation method thereof. Background Art

[0002] With the improvement of living standards, floor heating, as a comfortable home heating method and a symbol of modern quality of life, has been increasingly accepted and used by more and more people and has been widely praised in the field of home heating. Floor heating can be divided into dry floor heating and wet floor heating. Compared with dry floor heating, wet floor heating has the advantages of energy saving, good heat storage, strong ground bearing capacity, uniform heat distribution, and low cost, making it more suitable for home heating needs.

[0003] In the prior art, wet floor heating systems consist of extruded panels, reflective film, floor heating pipes, silicon crystal mesh, staples, and a pebble concrete backfill layer. The overall installation height is relatively high, and the backfill layer is typically pebble concrete. Concrete backfill requires watering and curing, making the surface prone to cracking. Furthermore, a single backfill cannot achieve a high level of flatness. Laying wooden floors requires secondary leveling to meet the required standards, resulting in a relatively complex process and high labor costs. Furthermore, the insulation panels installed beneath the floor heating pipes are typically flat. During the installation of the pipes, an additional layer of reflective film is required. The spacing between the pipes is determined by counting the grids on the film. Furthermore, staples are typically used to secure the pipes in place, creating holes in the insulation panels. Heat radiated from the pipes is dissipated downwards through the staple holes. Furthermore, ensuring that the horizontal and vertical alignment of the staples is achieved during construction is time-consuming, complex, and inefficient.

[0004] In the existing technology, the dry floor heating insulation structure uses insulation board + gaskets for secondary leveling. When the surface is wooden flooring, after the floor keel is laid, pads are used to level the insulation board with the keel at the uneven area under the insulation board. This method has the following disadvantages: there is a gap between the edge of the insulation board and the keel, resulting in heat loss and energy waste; the height of the padding at the bottom of the insulation board is uncertain and requires on-site testing, resulting in low construction efficiency.

[0005] Chinese patent [CN202110494524.0] discloses a floor heating structure, including a positioning plate, a floor heating coil and a backfill layer arranged in sequence from bottom to top; the positioning plate includes an insulation plate and a plurality of positioning columns arranged on one side of the insulation plate, the plurality of positioning columns are distributed in an array, and there is a spacing between adjacent positioning columns for the floor heating coil to pass through, the distance between each two adjacent rows of positioning columns is equal, and the distance between each two adjacent columns of positioning columns is equal, the first end of the positioning column is fixedly connected to the insulation plate, and the second end is provided with a limiting structure for limiting the floor heating coil from escaping upward; the material of the backfill layer is backfill leveling mortar.

[0006] The floor heating structure can adjust the keel or base plate without reducing the strength of the keel or base plate, and the keel or base plate has good stability. However, the floor heating structure is complex, especially the positioning plate production process is complex, the production cost is high, and the production and installation efficiency is low. Summary of the Invention

[0007] The purpose of the present invention is to provide a dry floor heating insulation board and an installation method thereof, in which the keels in the floor heating insulation board structure can be pre-assembled and integrated, which is convenient for rapid laying and installation on site, and the limiting parts can be directly inserted into the clamping grooves of the keels on both sides, and the insulation board can be quickly embedded in the grooves of the limiting parts, so that there is no gap between the edge of the insulation board and the keel, the heat loss is small, the insulation board structure is stable and firm, and the installation efficiency is high.

[0008] To achieve the above-mentioned objectives, on the one hand, the present invention provides a dry floor heating insulation board, including a moisture-proof pad laid above the original ground, at least two keels laid above the moisture-proof pad, a positioning piece arranged above the moisture-proof pad and used to fix the keel, and a limiting piece arranged between two adjacent keels and used to fix and install the insulation board.

[0009] A further preferred technical solution is that the keel includes a lower keel and an upper keel that is clamped with the lower keel, and an adjustment bolt for adjusting the height position of the upper keel is provided between the lower keel and the upper keel, the adjustment bolt is clamped and fixed with the lower keel, and the adjustment bolt is screwed and fixed with the upper keel.

[0010] A further preferred technical solution is that a plurality of the adjusting bolts are evenly spaced apart between the lower keel and the upper keel.

[0011] A further preferred technical solution is that gaps for the pipeline to pass through are provided at corresponding positions of the lower keel, the upper keel and the limiting member.

[0012] A further preferred technical solution is that both the upper keel and the lower keel are porous hollow structures.

[0013] A further preferred technical solution is that the limiting part includes a concave plate for laying and installing the insulation board, and gusset plates arranged on both sides of the concave plate. The upper surface of the upper keel is provided with a snap-in groove along the length direction of the keel, and the two gusset plates can be embedded in the snap-in groove at the same time to form a stable structure.

[0014] A further preferred technical solution is that the limiting member is made of metal material.

[0015] A further preferred technical solution is that the positioning member includes a positioning plate arranged on one side of the original wall, and the bottom of the positioning plate is provided with a positioning groove for clamping the positioning keel, and the two ends of the keel can be inserted into the positioning groove to form a stable structure.

[0016] A further preferred technical solution is that: a plurality of positioning grooves are evenly spaced apart at the bottom of the positioning plate, and the distance between two adjacent positioning grooves is the same as the width of the concave plate.

DETAILED DESCRIPTION

[0032] In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work. In addition, the design orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0033] The embodiments of the present invention are as follows:

[0034] like Figures 1 to 5 As shown, a dry floor heating insulation board includes a moisture-proof pad 1 laid above the original ground, at least two keels 2 laid above the moisture-proof pad 1, a positioning member 3 arranged above the moisture-proof pad 1 and used to fix the keel 2, and a limiting member 5 arranged between two adjacent keels 2 and used to fix and install the insulation board 4.

[0035] In this embodiment, after the moisture-proof mat 1 is laid, a relative positioning member 3 is provided on each of the two opposite walls, and the positioning members 3 are arranged along the corners of the wall. At least two keels 2 are also laid above the moisture-proof mat 1, and the two ends of each keel 2 are respectively inserted into the two opposite positioning members 3, and different keels 2 are arranged parallel to each other.

[0036] Secondly, a limiting member 5 is clamped between each two adjacent keels 2, and the insulation board 4 can be directly installed on the limiting member 5. In this way, the insulation board 4 does not directly contact the keel 2, but is clamped and fixed to the keel 2 by the limiting member 5. Therefore, there is no gap between the insulation board 4 and the keel 2, which not only facilitates installation but also avoids heat loss.

[0037] In addition, the insulation board 4 can be fixed to the stopper 5 by bonding to enhance the stability of the insulation board 4. This can be done by pre-applying adhesive to the stopper 5. The keel 2 can be fixed to the original ground with nails or snap-fitted to ground fixings (not shown) to further enhance the stability of the keel 2.

[0038] The keel 2 includes a lower keel 201 and an upper keel 202 that is engaged with the lower keel 201. An adjustment bolt (not shown in the figure) for adjusting the height position of the upper keel 202 is provided between the lower keel 201 and the upper keel 202. The adjustment bolt is engaged and fixed with the lower keel 201, and the adjustment bolt is screwed and fixed with the upper keel 202.

[0039] In this embodiment, the height of the upper keel 202 can be quickly adjusted by rotating the adjusting bolt. Therefore, when the keel is laid on site, the lower keel 201 and the upper keel 202 can be assembled in advance. After the keel is laid, the keel structure can be leveled by rotating the adjusting bolt, which can save a lot of installation steps and improve installation efficiency.

[0040] A plurality of adjusting bolts are evenly spaced between the lower keel 201 and the upper keel 202. The adjusting bolts are mainly used to support the upper keel 202, so the even arrangement of the adjusting bolts can make the supporting force on the upper keel 202 more stable and uniform.

[0041] In the existing technology, the position of floor heating pipes is generally fixed with staples. However, in actual construction, it takes a long time to truly achieve "horizontal and vertical staples", the process is complicated, and the laying efficiency is low.

[0042] Therefore, in this embodiment, notches 7 for pipe passage are provided at corresponding locations on the lower keel 201, the upper keel 202, and the stopper 5. These notches 7 not only facilitate pipe threading but also effectively position the pipes, preventing them from deviating. Furthermore, the locations of these notches 7 can be pre-designed during material production, eliminating the need for on-site drilling and significantly improving on-site installation efficiency.

[0043] The upper keel 202 and the lower keel 201 are both porous hollow structures. The porous hollow structure of the keel can make the keel lightweight and convenient for installation and transportation.

[0044] In the prior art, in order to keep the keel flush with the insulation board, pads are used at the uneven area below the insulation board to make the insulation board flush with the keel, so that the overall structure remains flat. However, this method requires multiple replacement and polishing of the pads in actual practice, which is a very troublesome process and consumes a lot of time.

[0045] Therefore, in this embodiment, the limiting member 5 includes a concave plate 501 for laying and installing the insulation board 4, and a buckle plate 502 arranged on both sides of the concave plate 501. The upper surface of the upper keel 202 is provided with a snap-in groove 203 along the length direction of the keel. The two buckle plates 502 can be embedded in the snap-in groove 203 at the same time to form a stable structure.

[0046] The engaging groove 203 passes through both ends of the upper keel 202, and the length of the concave plate 501 can be the same as that of the upper keel 202. In this way, when the gusset plates 502 of two adjacent limiting members 5 are simultaneously inserted into one engaging groove 203, they can fully cover the middle upper keel 202. The length of the concave plate 501 can also be half the length of the upper keel 202. In this way, two limiting members 5 need to be provided between each two adjacent keels and spliced ​​together end to end to cover the entire keel.

[0047] Therefore, the adjacent keels are leveled by the adjusting bolts, and then the clip plates 502 on both sides of the limiting member 5 are respectively embedded in the snap-fit ​​grooves 203 on the keels on both sides, and each of the snap-fit ​​grooves 203 can embed two of the clip plates 502 at the same time, that is, each keel can simultaneously support the two adjacent limiting members 5, and the snap-fit ​​groove 203 located closest to the edge on one side can only embed one of the clip plates 502, and then maintain stability by inserting a pad.

[0048] In this embodiment, the limiting member 5 is made of metal material, which has high strength, is not easily deformed, and can provide sufficient supporting force.

[0049] Finally, the positioning member 3 includes a positioning plate 301 arranged on one side of the original wall 6. The bottom of the positioning plate 301 is provided with a positioning groove 302 for clamping the positioning keel. The two ends of the keel 2 can be inserted into the positioning groove 302 to form a stable structure.

[0050] In this embodiment, by rotating the adjusting bolt, the height of the keel 2 can be made flush with the positioning plate 301, so that the overall structure is smoother and there is no need to grind the positioning plate 301 separately at a later stage.

[0051] A plurality of positioning grooves 302 are evenly spaced at the bottom of the positioning plate 301 , and the distance between two adjacent positioning grooves 302 is the same as the width of the concave plate 501 .

[0052] In this embodiment, when the gusset plate 502 is inserted into the engaging groove 203, the outer side walls of the concave plate 501 respectively contact the keels 2 on both sides, thereby enhancing the stability of the stopper 5. Furthermore, when the insulation board 4 is installed inside the concave plate 501, the two sides of the insulation board 4 contact the inner side walls of the concave plate 501, eliminating a gap between the insulation board 4 and the stopper 5, thereby reducing heat loss and improving the insulation effect.

[0053] A method for installing a dry floor heating insulation board comprises the following steps:

[0054] S1. First, lay a moisture-proof mat 1 on the original ground, and then install the positioning piece 3 along the original wall 6;

[0055] S2. Assemble the upper keel 202 and the lower keel 201 together by adjusting the bolts. Then insert the ends of the assembled keels 2 into the positioning slots 302 of the positioning members 3 and fix them in place. Rotate the adjusting bolts to keep the upper keel 202 horizontal and fixed. Install all the keels 2 in this manner.

[0056] S3. Then, insert the gusset plate 502 of the limiting member 5 into the snap-fit ​​grooves 203 of two adjacent upper keels 202, and strengthen the connection between the gusset plate 502 and the upper keel 202 with screws. Each snap-fit ​​groove 203 can fit two gusset plates 502. Install all the limiting members 5 in this way.

[0057] S4. Finally, the insulation board is laid in the concave plate 501 of the limiting member 5 to complete the installation.
