Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation exterior wall technology and relates to a foamed ceramic in-situ repair system. Background Technology

[0002] In the field of exterior wall insulation repair, traditional repair methods have obvious drawbacks. Replacement repair requires the removal and replacement of the entire system or parts of it. This method is mostly temporary and emergency repairs, which can easily lead to cracking, hollowing, and other quality problems in the repaired exterior wall. Thick-layer in-situ repair involves a thicker plaster layer, and its repair effect is greatly affected by the construction quality, resulting in poor stability. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a foamed ceramic in-situ repair system.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A foamed ceramic in-situ repair system includes a concrete wall and an existing insulation layer disposed on the outside of the concrete wall. A foamed ceramic insulation board is disposed on the outside of the existing insulation layer and fixed by a number of anchors. The outer surface of the existing insulation layer is also coated with a leveling layer, and an adhesive layer is provided between the leveling layer and the foamed ceramic insulation board.

[0006] In the aforementioned foamed ceramic in-situ repair system, the anchor includes a hollow outer round rod. The inner end of the outer round rod passes through the foamed ceramic insulation board and the existing insulation layer and is inserted into the concrete wall. The inner end of the outer round rod is provided with a limiting member in a closed state. The outer round rod is also provided with an inner round rod that can drive the limiting member to open into a flared state. The outer end of the outer round rod is also provided with a tail plate.

[0007] In the aforementioned foamed ceramic in-situ repair system, the limiting component consists of several fan-shaped connecting pieces arranged circumferentially along the axis of the outer round rod. Each fan-shaped connecting piece has an abutment block that can abut against the inner round rod. When the limiting component is in the closed state, the several fan-shaped connecting pieces form a cone shape. When the inner round rod moves towards the inner end of the outer round rod, the abutment block can push the fan-shaped connecting pieces open until the outer diameter of the circular plane formed by connecting the outer ends of the several fan-shaped connecting pieces is greater than the outer diameter of the outer round rod.

[0008] In the above-mentioned foamed ceramic in-situ repair system, the foamed ceramic insulation board, the existing insulation layer and the concrete wall are respectively provided with a first connection hole, a second connection hole and a connection groove for inserting anchors, and the inner end of the connection groove has a flared part corresponding to the limiting member.

[0009] In the above-mentioned foamed ceramic in-situ repair system, the outer side of the foamed ceramic insulation board is recessed inward with a non-through groove, and the tail plate can be embedded into the non-through groove. The cross-section of the non-through groove and the tail plate is circular, and the non-through groove is also filled with sealing material.

[0010] In the above-mentioned foamed ceramic in-situ repair system, the diameter of the non-through groove is not less than the diameter of the tail plate, and the depth of the non-through groove is less than the thickness of the foamed ceramic insulation board.

[0011] The sealing material is a cement-based adhesive.

[0012] In the above-mentioned foamed ceramic in-situ repair system, the leveling layer is cement mortar; the bonding layer is cement-based adhesive.

[0013] In the aforementioned foamed ceramic in-situ repair system, the anchor is made of stainless steel.

[0014] In the above-mentioned foamed ceramic in-situ repair system, the dry density of the foamed ceramic insulation board is not less than 350 kg / m3 and the compressive strength is not less than 5 MPa.

[0015] In the above-mentioned foamed ceramic in-situ repair system, the foamed ceramic insulation board is further provided with a plaster layer and a decorative layer on the outside, and the decorative layer is located on the outside of the plaster layer.

[0016] The plastering layer is a plastering mortar with fiberglass mesh sandwiched in it; the finishing layer is a coating.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] 1. The system described in this utility model sets a leveling layer and an adhesive layer on the outside of the existing insulation layer, and fixes the foamed ceramic insulation board with anchors to form a non-destructive repair structure, avoiding large-area removal; the leveling layer ensures the flatness of the base layer, the adhesive layer enhances the adhesion between the foamed ceramic insulation board and the existing insulation layer, and the anchors further strengthen the fixation. This design solves the cracking and hollowing problems of traditional repairs and improves the overall stability and insulation performance of the exterior wall.

[0019] 2. Foamed ceramic insulation boards can be used as protective boards. They have low water absorption, good thermal insulation properties, and can improve the overall performance of exterior walls. Foamed ceramic insulation boards have good plasticity and can be used as decorative components to enhance the aesthetics of the facade.

[0020] 3. The anchor uses an external round rod in conjunction with an internal round rod and a limiting component. When the limiting component is closed, it can be easily inserted. After insertion, the internal round rod moves to open the limiting component into a flared state, so that the anchor is mechanically locked to the concrete wall. This structure solves the problem of traditional anchoring methods being prone to falling off due to wind suction, enhances the connection reliability between the foamed ceramic insulation board and the wall, and improves the system's resistance to falling off.

[0021] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

Detailed Implementation

[0027] like Figures 1-4 As shown, a foamed ceramic in-situ repair system includes a concrete wall 1 and an existing insulation layer 2 disposed on the outside of the concrete wall 1. A foamed ceramic insulation board 5 is disposed on the outside of the existing insulation layer 2 and fixed by a number of anchors 6. The outer surface of the existing insulation layer 2 is also coated with a leveling layer 3. An adhesive layer 4 is also provided between the leveling layer 3 and the foamed ceramic insulation board 5.

[0028] The system described in this utility model sets a leveling layer and an adhesive layer on the outside of the existing insulation layer, and fixes the foamed ceramic insulation board with anchors to form a non-destructive repair structure, avoiding large-area removal; the leveling layer ensures the flatness of the base layer, the adhesive layer enhances the adhesion between the foamed ceramic insulation board and the existing insulation layer, and the anchors further strengthen the fixation. This design solves the cracking and hollowing problems of traditional repairs and improves the overall stability and insulation performance of the exterior wall.

[0029] In addition, foamed ceramic insulation boards can be used as protective boards. They have low water absorption, thermal insulation properties, and can improve the overall performance of exterior walls. Foamed ceramic insulation boards have good plasticity and can be used as decorative components to increase the aesthetics of the facade.

[0030] Specifically, the anchor 6 includes a hollow outer round rod 62. The inner end of the outer round rod 62 passes through the foamed ceramic insulation board 5 and the existing insulation layer 2 and is inserted into the concrete wall 1. The inner end of the outer round rod 62 is provided with a limiting member 63 in a closed state. The outer round rod 62 also has an inner round rod 64 that can drive the limiting member 63 to open into a flared state. The outer end of the outer round rod 62 is also provided with a tail plate 61. The anchor uses an outer round rod in conjunction with an inner round rod and a limiting member. When the limiting member is closed, it can be easily inserted. After insertion, the inner round rod moves to drive the limiting member to open into a flared state, so that the anchor is mechanically locked to the concrete wall. This structure solves the problem of traditional anchoring methods being prone to falling off due to wind suction, enhances the connection reliability between the foamed ceramic insulation board and the wall, and improves the system's resistance to falling off.

[0031] Specifically, the limiting member 63 consists of several fan-shaped connecting pieces 65 arranged circumferentially along the axis of the outer round rod 62. Each fan-shaped connecting piece 65 has an abutting block 66 that can abut against the inner round rod 64. When the limiting member 63 is in the closed state, the fan-shaped connecting pieces 65 form a cone shape. When the inner round rod 64 moves towards the inner end of the outer round rod 62, the abutting block 66 can push the fan-shaped connecting pieces 65 open until the outer diameter of the circular plane formed by the connecting outer ends of the fan-shaped connecting pieces 65 is greater than the outer diameter of the outer round rod 62. The limiting member's design, with its fan-shaped connecting pieces forming a cone shape, creates a circular plane with an outer diameter greater than the outer round rod after opening, increasing the contact area with the concrete wall. This structure evenly distributes the anchoring stress, avoiding damage to the insulation board caused by localized stress concentration, and ensuring the long-term stable fixation of the foamed ceramic insulation board.

[0032] Specifically, the foamed ceramic insulation board 5, the existing insulation layer 2, and the concrete wall 1 are respectively provided with a first connecting hole, a second connecting hole, and a connecting groove for inserting anchors 6. The inner end of the connecting groove has a flared portion 11 corresponding to the limiting member 63. The flared portion at the inner end of the connecting groove cooperates with the opened limiting member to form a precise positioning structure, ensuring that the limiting member is fully embedded in the flared portion. This design avoids axial displacement of the anchors, eliminates loosening of the insulation board caused by anchor offset, and enhances the consistency of the overall system structure.

[0033] Specifically, the foamed ceramic insulation board 5 has a non-through groove 51 recessed inward on its outer side. The tail plate 61 can be embedded into the non-through groove 51. The cross-section of the non-through groove 51 and the tail plate 61 is circular. The non-through groove 51 is also filled with sealing material 7. The non-through groove of the foamed ceramic insulation board allows the tail plate to be embedded, and together with the sealing material, a closed protective structure is formed: the groove prevents the tail plate from being exposed and affecting subsequent construction, and the sealing material prevents moisture from seeping into the anchor. This design solves the problem of traditional anchors being easily corroded, while protecting the structural integrity of the foamed ceramic insulation board and extending the service life of the system.

[0034] Specifically, the diameter of the non-through groove 51 is not less than the diameter of the tail plate 61, and the depth of the non-through groove 51 is less than the thickness of the foamed ceramic insulation board 5; the sealing material 7 is a cement-based adhesive. The diameter and depth of the non-through groove are adapted to the tail plate size, so that the tail plate is fully embedded and the sealing material makes the tail plate and the non-through groove fit tightly; this design ensures a reliable sealing effect, prevents moisture from seeping into the wall along the tail plate, and avoids the groove being too deep, which weakens the strength of the insulation board, thus balancing protection and structural stability.

[0035] Specifically, the cement-based adhesive used in sealing material 7 is a C1 grade cement-based adhesive.

[0036] Specifically, leveling layer 3 is cement mortar; bonding layer 4 is cement-based adhesive. The use of cement mortar for the leveling layer and cement-based adhesive for the bonding layer improves the surface smoothness of the existing insulation layer, ensuring a tight bond between the foamed ceramic insulation board and the substrate. This design solves the problem of hollow areas caused by weak traditional bonding, enhances the overall system integrity, and reduces stress cracking caused by uneven substrate.

[0037] Preferably, the cement-based adhesive used in the adhesive layer 4 is a C1 grade cement-based adhesive.

[0038] Preferably, anchor 6 is made of stainless steel. The stainless steel material provides corrosion resistance and adapts to the complex environment of exterior walls. This design avoids the strength degradation caused by corrosion in traditional metal anchors, ensuring long-term stable anchoring force and improving the system's durability in humid and high-temperature environments.

[0039] Preferably, the dry density of the foamed ceramic insulation board 5 is not less than 350 kg / m³, and the compressive strength is not less than 5 MPa. The high dry density and compressive strength of the foamed ceramic insulation board enable it to combine thermal insulation function with structural load-bearing capacity. This design solves the problem of insufficient strength and easy breakage of traditional insulation materials, and can serve as a protective layer to resist external impacts while maintaining good thermal insulation performance.

[0040] Preferably, the foamed ceramic insulation board 5 is further provided with a plastering layer 8 and a finishing layer 9 on its outer side, with the finishing layer 9 located outside the plastering layer 8; the plastering layer 8 is a plastering mortar with fiberglass mesh sandwiched in it; the finishing layer 9 is a paint. The plastering layer being a plastering mortar with fiberglass mesh sandwiched in it, and the finishing layer being a paint, forms a multi-layered protective structure: the fiberglass mesh enhances the crack resistance of the plastering layer, and the paint improves the surface weather resistance. This design solves the problems of easy cracking of traditional plastering layers and easy aging of finishing layers, while also making the exterior wall appearance neat and improving the overall decorative and protective effect of the system.

[0041] The working principle of this utility model is as follows:

[0042] Step 1: Set a leveling layer 3 and an adhesive layer 4 on the surface of the existing insulation layer 2;

[0043] Step 2: After the foamed ceramic insulation board 5 comes into contact with the adhesive layer 4, a special drilling machine with flaring function is used to drill through the existing insulation layer 2, leveling layer 3, adhesive layer 4 and foamed ceramic insulation board 5 to form the first connecting hole, the second connecting hole, the connecting groove and the flared part 11, and the drilling depth is located inside the concrete wall 1.

[0044] Step 3: Insert the anchor 6 into the hole of the special drilling machine, and pass the inner round rod 64 of the anchor 6 through the outer round rod 62 to the limiting member 63. The limiting member 63 will open into a flared state to form a reliable anchor.

[0045] Step 4: Apply a finishing layer 8 and a decorative layer 9 to the surface of the foamed ceramic insulation board 5.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0047] Although this article frequently uses terms such as concrete wall 1, existing insulation layer 2, leveling layer 3, adhesive layer 4, foamed ceramic insulation board 5, anchor 6, sealing material 7, plastering layer 8, finishing layer 9, flared part 11, non-through groove 51, tail plate 61, external round rod 62, limiting part 63, internal round rod 64, fan-shaped connecting piece 65, etc., these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would be contrary to the spirit of this utility model.
