Description

Technical Field

[0001] This invention belongs to the field of connector technology, and relates to a fixing connector for insulation boards in a thin plastering system for buildings and its usage method. Background Technology

[0002] The basic structure of thin-plaster systems for construction, from the inside out, includes: base wall, bonding layer, insulation layer, plastering layer, and finishing layer. Base wall includes: reinforced concrete walls and various masonry walls (masonry walls require leveling with cement mortar). The bonding layer is an adhesive, and the bonding area must not be less than 50% of the insulation layer area. The insulation layer uses insulation boards. The plastering layer is a plastering mortar composite with fiberglass mesh (reinforced versions have an additional layer of fiberglass mesh). The finishing layer is either paint or finishing mortar.

[0003] After the insulation layer is fixed to the base wall by the adhesive layer, the traditional method is to reinforce the insulation layer with ordinary insulation nails (single-head nails), with the entire nail not protruding from the insulation layer, thus failing to provide anchoring force between the plaster layer and the base wall. When applying the plaster layer, it relies on the adhesive force of the bonding mortar to adhere to the insulation layer. Over time, the plaster layer is prone to detachment due to mortar hollowing and other reasons.

[0004] Therefore, a fixing connector for insulation boards in a thin plastering system for buildings that can prevent the plaster layer from peeling off and its usage method are designed. Summary of the Invention

[0005] To at least address the problems in existing thin-plaster building systems where ordinary insulation nails are used to reinforce the insulation layer, resulting in the nails not being exposed and failing to provide anchorage between the plaster layer and the base wall, leading to easy detachment of the plaster layer, this invention provides the following technical solution: a fixing connector for an insulation board in a thin-plaster building system, wherein the thin-plaster building system comprises, from the inside out, a base wall, an adhesive layer, an insulation layer, a plaster layer, and a finishing layer, and the insulation board fixing connector comprises:

[0006] The limiting component is installed on the outside of the insulation layer via a pressure plate; and

[0007] The material-blocking nail includes: a material-blocking part, a working part, and a pre-embedded part connected in sequence. The working part is located in the center hole of the limiting member. The pre-embedded part passes through the insulation layer and the adhesive layer in sequence and extends into the base wall. The working part and the limiting member cooperate with each other to adjust the distance between the material-blocking part and the limiting member.

[0008] Optionally, in the above-mentioned building thin plastering system insulation board fixing connector, the distance between the material blocking part and the limiting part is 1 to 10 mm.

[0009] Optionally, in the above-mentioned building thin plastering system insulation board fixing connector, the length of the embedded part is greater than the length of the limiting member.

[0010] Optionally, in the above-mentioned fixing connector for the insulation board of the thin plastering system for buildings, the working part is threadedly connected to the limiting member; or

[0011] The outer diameter of the working part is larger than the outer diameter of the embedded part, and the working part is tightly fitted with the limiting member.

[0012] Optionally, in the above-mentioned building thin plastering system insulation board fixing connector, the limiting member includes: a limiting cap;

[0013] The inner diameter of the limiting cap is smaller than the outer diameter of the material blocking part, and the limiting cap is detachably connected to the pressure plate.

[0014] Optionally, in the above-mentioned building thin plastering system insulation board fixing connector, the limiting component further includes: a limiting sleeve;

[0015] One end of the limiting cap extends outward to form the limiting sleeve;

[0016] The center hole of the limiting sleeve is connected to the center hole of the limiting cap, and the limiting sleeve is used to increase the screw force of the limiting member.

[0017] Optionally, in the above-mentioned building thin plastering system insulation board fixing connector, the insulation board fixing connector further includes: an expansion bolt, the expansion bolt including: the pressure plate, the expansion plug and the pre-embedded part;

[0018] The outer diameter of the pressure plate is larger than the outer diameter of the expansion plug;

[0019] The expansion plug has an inner cavity communicating with the center hole of the pressure plate, the inner cavity being used to accommodate the pre-embedded part, and the expansion plug is connected to the pressure plate.

[0020] Optionally, in the above-mentioned fixing connectors for insulation boards in thin-plaster building systems, the expansion plug and the pressure plate are detachably connected; or

[0021] The expansion plug and the pressure plate are integrally formed.

[0022] Optionally, in the above-mentioned fixing connectors for insulation boards in thin-plastered building systems, both the material-blocking part and the limiting cap are in the shape of an inverted frustum cone; and

[0023] The diameter of the embedded part is 3 to 5 mm, and the embedded part has a pointed tip.

[0024] This invention also provides the following technical solution: a method for using a fixing connector for a thin-plastered building insulation board, the method being applicable to the fixing connector for a thin-plastered building insulation board as described above, the method comprising the following steps:

[0025] S1. Install the limiting component on the outside of the insulation layer using a pressure plate;

[0026] S2. Insert the material blocking nail into the center hole of the limiting component, so that the embedded part passes through the insulation layer and the adhesive layer in sequence and extends into the base wall until the working part is in the center hole of the limiting component.

[0027] S3. The operating unit adjusts the distance between the material blocking part and the limiting part.

[0028] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows:

[0029] This application solves the problem of using double-cap nails, with the upper layer being a material-blocking nail and the lower layer being a limiting member. The limiting member can fix the pressure plate. The working part of the material-blocking nail and the limiting member cooperate with each other. The distance between the material-blocking part of the material-blocking nail and the limiting member can be adjusted according to actual needs. The material-blocking part is used to increase the anchoring points between the plaster layer and the base wall, achieving the integration of the structure and the plaster layer. This solves the problem in the existing technology of using ordinary insulation nails to reinforce the insulation layer in thin plastering systems for buildings. The insulation nails do not protrude from the insulation layer and cannot provide anchoring force between the plaster layer and the base wall, making the plaster layer prone to falling off.

[0036] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0037] In the description of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and do not require the invention to be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. The terms "connected," "linked," and "set up" used in this invention should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a direct connection or an indirect connection through intermediate components; a wired connection, a radio connection, or a wireless communication signal connection. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0038] Please see Figure 1-4 The present invention provides the following technical solution: a fixing connector for insulation boards in a thin plastering system for buildings, as shown in the reference. Figure 1 As shown, the fixing connectors for this insulation board include: material blocking nail 1, limiting component 2, and expansion bolt 3.

[0039] Building thin-plaster system 4 includes: from the inside out (in...) Figure 2 and Figure 5 The layers shown in the image (from right to left) are: base wall 41, adhesive layer 42, insulation layer (i.e., insulation board) 43, plaster layer 44, and finishing layer 45.

[0040] The limiting member 2 is installed on the outside of the insulation layer 43 via the pressure plate 31 (which is part of the expansion bolt 3; the specific structure of the expansion bolt 3 is not limited in this embodiment). It can be understood that the limiting member 2 can fix the pressure plate 31.

[0041] The material-blocking nail 1 includes a material-blocking part 11, a working part 12, and a pre-embedded part 13 connected in sequence. The working part 12 of the material-blocking nail 1 is located in the center hole of the limiting member 2. It can be understood that the length of the pre-embedded part 13 of the material-blocking nail 1 is greater than the length of the limiting member 2. The material-blocking nail 1 and the limiting member 2 form a double-cap nail, and the working part 12 of the material-blocking nail 1 and the limiting member 2 cooperate with each other to adjust the material-blocking part 11 of the material-blocking nail 1 (in...). Figure 1 In the image shown, the material blocking part 11 is the upper cap of the double cap nail, and the limiting part 2 is in Figure 1 In the image shown, the distance between the lower cap of the double-cap nail (limiting member 2) can also be understood as the distance between the two caps of the double-cap nail. Regarding the understanding of "mutual cooperation," in this embodiment, it can be rephrased as the connection method between the working part 12 and the limiting member 2, such as threaded connection, tight fit, etc. This embodiment does not limit the specific connection method between the material-blocking nail 1 and the limiting member 2, as long as the distance between the two caps of the double-cap nail can be adjusted. The pre-embedded part 13 of the material-blocking nail 1 passes through the insulation layer 43 and the adhesive layer 42 in sequence and extends into the base wall 41, thus connecting the insulation layer 43 and the base wall 41, thereby preventing the insulation layer 43 from falling off the base wall 41. The material-blocking part 11 of the material-blocking nail 1 is used to increase the anchoring points between the plaster layer 44 and the base wall 41, achieving structural integration with the plaster layer 44, solving the problem of using ordinary insulation nails 5 (single-cap nails) to reinforce the insulation layer 43 in the existing thin plastering system 4 for building applications. (Refer to...) Figure 5 As shown, the entire insulation nail 5 does not expose the insulation layer 43, thus failing to provide anchoring force between the plaster layer 44 and the base wall 41, leading to the problem of the plaster layer 44 easily detaching. It should be noted that... Figure 2 In the image shown, label 1 refers not only to the material blocking nail 1, but also to the limiting component 2 and the expansion bolt 3. That is, label 1 actually represents the fixing connection of the insulation board of the entire thin plastering system for buildings.

[0042] During installation, the pressure plate 31 is pressed onto the outside of the insulation layer 43 using the limiting member 2. The retaining nail 1 is aligned with the center hole of the limiting member 2. The retaining nail 1 is operated by rotating and pressing, so that the pre-embedded part 13 of the retaining nail 1 passes through the insulation layer 43 and the adhesive layer 42 in sequence and extends into the base wall 41. At this time, the working part 12 of the retaining nail 1 is located in the center hole of the limiting member 2. Figure 1 In the image shown, the limiting member 2 connected to the pressure plate 31 is fixed in place. By rotating or moving the material blocking nail 1, the working part 12 and the limiting member 2 cooperate with each other. The working part 12 moves the fixed material blocking part 11 upward or downward relative to the limiting member 2, thereby realizing the distance adjustment between the material blocking part 11 of the material blocking nail 1 and the limiting member 2, that is, realizing the distance adjustment between the two caps in the double-cap nail.

[0043] It should be noted that when setting up the formwork, the material blocking nail 1 needs to be removed from the limiting part 2 first, and the material blocking nail 1 should be reinstalled into the limiting part 2 when the cement leveling layer is to be applied.

[0044] As a preferred embodiment of the above embodiment, in this embodiment, considering that some parts of the wall may be uneven, the distance between the material blocking part 11 of the material blocking nail 1 and the limiting member 2 is 1 to 10 mm, such as 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or other values ​​within this range. Preferably, the distance between the material blocking nail 1 and the limiting member 2 is adjusted to a preset value by a spiral engagement, so as to ensure the flatness of the plaster layer 44.

[0045] As an embodiment of the specific connection method between the working part 12 and the limiting member 2, in this embodiment, the first method is: the working part 12 and the limiting member 2 are threadedly connected, that is, the distance between the two caps of the material blocking nail 1 and the limiting member 2 is adjusted by a screw. Simply put, the position of the limiting member 2 is fixed, and the material blocking nail 1 is rotated. The working part 12 and the limiting member 2 cooperate with each other to adjust the relative distance between the two caps of the double-cap nail to a preset value. Specifically, the outer wall of the working part 12 of the material stop nail 1 is provided with an external thread along the length direction of the working part 12, and the center hole of the limiting member 2 is provided with an internal thread that matches the external thread. In this way, by rotating the material stop nail 1, the torque of the working part 12 of the material stop nail 1 is converted into linear motion. The working part 12, along with the fixed material stop part 11, moves upward or downward relative to the limiting member 2, thereby increasing or decreasing the distance between the material stop part 11 of the material stop nail 1 and the limiting member 2, thus realizing the distance adjustment between the material stop part 11 of the material stop nail 1 and the limiting member 2, that is, realizing the distance adjustment between the two caps in the double-cap nail. The second method is as follows: the material-blocking nail 1 is a variable diameter nail, and the material-blocking nail 1 and the limiting member 2 are tightly fitted (referring to a method of achieving the connection purpose through the frictional resistance generated by the interference fit). Specifically, the outer diameter of the working part 12 of the material-blocking nail 1 is larger than the outer diameter of the embedded part 13 of the material-blocking nail 1. At the same time, the working part 12 of the material-blocking nail 1 is tightly fitted with the limiting member 2. That is to say, the outer diameter of the working part 12 of the material-blocking nail 1 and the inner diameter of the limiting member 2 are interference fitted. In this way, by moving the material-blocking nail 1, the material-blocking part 11 of the material-blocking nail 1 can be axially moved relative to the limiting member 2. The specific direction of movement is determined according to the actual needs, thereby realizing the distance adjustment between the material-blocking part 11 of the material-blocking nail 1 and the limiting member 2, that is, realizing the distance adjustment between the two caps in the double-cap nail.

[0046] Reference Figure 3As shown in the embodiment of the specific structure of the aforementioned limiting member 2, in this embodiment, the limiting member 2 includes a limiting cap 21. The inner diameter of the limiting cap 21 is smaller than the outer diameter of the material blocking portion 11 of the material blocking nail 1, so that the material blocking portion 11 is always located outside the limiting cap 21. The limiting cap 21 is detachably connected to the pressure plate 31. Preferably, the limiting cap 21 and the pressure plate 31 are threaded together. Specifically, the outer side wall of the limiting cap 21 is provided with an external thread, and the inner side wall of the center hole of the pressure plate 31 is provided with a matching internal thread. Thus, when the working part 12 is operated (e.g., rotated), the limiting member 2 and the pressure plate 31 are fixedly connected together and do not rotate. It is worth mentioning that when the working part 12 is threadedly connected to the limiting member 2 (referring to the limiting cap 21), the direction of rotation of the internal thread of the limiting cap 21 is opposite to the direction of rotation of the external thread of the limiting cap 21. Thus, when the working part 12 is rotated, the limiting member 2 will not rotate within the pressure plate 31. In addition, the limit cap 21 and the pressure plate 31 can also be connected by a tight fit.

[0047] Reference Figure 4 As shown, in another specific embodiment of the aforementioned limiting member 2, the limiting member 2 includes a limiting cap 21 and a limiting sleeve 22. Specifically, one end of the limiting cap 21 extends outward to form the limiting sleeve 22, and the central hole of the limiting sleeve 22 communicates with the central hole of the limiting cap 21. The limiting sleeve 22 is used to increase the screw force (mainly including pull-out resistance) of the limiting member 2.

[0048] As an embodiment of the specific structure of the expansion bolt 3 described above, in this embodiment, the expansion bolt 3 includes: a pressure plate 31, an expansion plug 32, and a pre-embedded part 13. Specifically, the outer diameter of the pressure plate 31 is larger than the outer diameter of the expansion plug 32. The expansion plug 32 has an inner cavity communicating with the central hole of the pressure plate 31. The expansion plug 32 and the pressure plate 31 are connected together, so that the inner cavity of the expansion plug 32 is used to accommodate the pre-embedded part 13 (e.g., Figure 1 As shown in the diagram, the pressure plate 31, the expansion plug 32, and the embedded part 13 work together on the base wall 41 to form an expansion bolt structure. It is worth mentioning that... Figure 2 In the image shown, the limiting sleeve 22 in the limiting member 2 is located inside the expansion plug 32. Furthermore, the expansion plug 32 and the pressure plate 31 are detachably connected (i.e., they are separate structures), such as by a threaded connection; or the expansion plug 32 and the pressure plate 31 are integrally formed. Both the pressure plate 31 and the expansion plug 32 are made of plastic.

[0049] Reference Figure 1 As shown, both the material blocking part 11 and the limiting cap 21 are in the shape of an inverted frustum; and the diameter of the embedded part 13 is 3-5 mm, the embedded part 13 has a pointed tip, which matches the shape of the bottom of the inner cavity of the expansion plug 32. The material blocking nail 1 and the limiting member 2 are both made of metal.

[0050] This invention also provides the following technical solution: a method for using a fixing connector for insulation boards in a thin plastering system for buildings. This method is applicable to the fixing connector for insulation boards in a thin plastering system for buildings as described above, and includes the following steps:

[0051] S1. Install the limiting member 2 on the outside of the insulation layer 43 via the pressure plate 31 (in this step, the limiting member 2 and the pressure plate 31 are connected).

[0052] The purpose of this step is to fix the pressure plate 31 to the insulation layer 43 by the limiting member 2.

[0053] S2. Insert the material blocking nail 1 into the center hole of the limiting member 2, and operate the material blocking nail 1 by rotating, pressing or other means, so that the pre-embedded part 13 of the material blocking nail 1 passes through the insulation layer 43 and the adhesive layer 42 in sequence and extends into the base wall 41 until the working part 12 of the material blocking nail 1 is in the center hole of the limiting member 2.

[0054] The purpose of this step is to connect the insulation layer 43 and the base wall 41 through the pre-embedded part 13 of the material blocking nail 1, to prevent the insulation layer 43 from falling off, and at the same time to make the material blocking part 11 and the pre-embedded part 13 of the material blocking nail 1 located on both sides of the radial side of the limiting member 2.

[0055] S3. The material blocking nail 1 is operated by rotating or moving. The working part 12 of the material blocking nail 1 and the limiting member 2 cooperate with each other to adjust the distance between the material blocking part 11 of the material blocking nail 1 and the limiting member 2.

[0056] The purpose of this step is to apply force directly to the working part 12 or directly to the material blocking part 11, so that the distance between the material blocking part 11 of the material blocking nail 1 and the limiting member 2 can be adjusted by rotating or moving the working part 12 with the material blocking part 11.

[0057] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
