Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building decoration technology, and more specifically, it relates to a high-strength decorative plastering structure that is easy to repair. Background Technology
[0002] In architectural decoration, plastering is the core process of wall treatment. Its quality directly affects the adhesion of the subsequent finishing layer and the service life of the overall building. Before construction, the wall base must be thoroughly inspected to remove floating dust, oil stains and other impurities. Hollow and cracked areas should be chiseled and repaired to ensure that the base is solid and flat. Then, a 1:3 cement mortar or mixed mortar is used for the base layer construction, and finally the decorative surface layer is constructed.
[0003] Existing application number: CN201621345193.5, describes a decorative cement plaster structure with a themed effect. It includes a decorative body with a workable surface, a galvanized metal plate with a diamond-shaped mesh fixed to its outer side, a base layer of cement mortar coated on the outer side of the metal plate, a top layer of cement mortar coated on the outer side of the base layer, and several horizontal roughened grooves on the outer surface of the top layer; a carved layer of cement mortar is also coated on the outer side of the top layer. This utility model, a decorative cement plaster structure with a themed effect, has a simple structure, stable appearance, and convenient construction. It achieves a consistent and stable final effect, providing an industry standard for the application of themed plastering, saving construction costs, and yielding significant economic benefits.
[0004] Based on the above, ordinary plastered structures are prone to cracking when faced with external impacts, such as minor collisions or building settlement, which affects the integrity and aesthetics of the wall. Moreover, after cracking occurs, existing repair techniques often require the entire wall surface in the cracked area to be removed and rebuilt. This not only involves complicated construction procedures but also presents a risk of secondary cracking due to the difficulty in treating the interface between the old and new mortars, resulting in high repair costs and long repair cycles. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides an easily repairable, high-strength decorative plastering structure. This solves the problem that existing ordinary plastering structures are prone to cracking when exposed to external impacts, such as minor collisions or building settlement, affecting the integrity and aesthetics of the wall. Moreover, existing repair processes often require the entire cracked area to be removed and rebuilt, which is not only cumbersome but also poses a risk of secondary cracking due to the difficulty in treating the interface between the old and new mortars, resulting in high repair costs and long repair cycles.
[0006] The purpose and effect of this utility model, which provides an easily repairable high-strength decorative plaster structure, are achieved through the following specific technical means:
[0007] A repairable, high-strength decorative plaster structure includes a wall, an interface treatment layer, a reinforcing skeleton layer, a bottom mortar layer, a crack-resistant mesh layer, a surface layer, easy-repair components, and fixing components. The interface treatment layer is sprayed onto the front surface of the wall. The reinforcing skeleton layer is positioned in front of the interface treatment layer. The bottom mortar layer is positioned in front of the interface treatment layer. The crack-resistant mesh layer is positioned in front of the bottom mortar layer. The surface layer is positioned inside and in front of the crack-resistant mesh layer. The easy-repair components are positioned in front of the bottom mortar layer. The fixing components are positioned in front of the wall.
[0008] Furthermore, the reinforcing skeleton layer is woven into a fiber mesh by interlacing high-strength fiber ribs with a diameter of three millimeters, and the overlap width of two adjacent reinforcing skeleton layers is ≥100mm.
[0009] Furthermore, the crack-resistant mesh layer is made of alkali-resistant glass fiber mesh with a mesh size of 4mm × 4mm and a unit area mass ≥160g / m². 2 The mesh fabric is laid horizontally with an overlap width of ≥100mm.
[0010] Furthermore, the easy-to-repair component includes: a partition column and a facial mortar layer; multiple partition columns are provided, and the multiple partition columns are dispersedly bonded to the front of the bottom mortar layer; the facial mortar layer is provided in front of the bottom mortar layer.
[0011] Furthermore, the fixing component includes: a fixing hole and an expansion sleeve; the fixing hole is opened inside the wall; the expansion sleeve is inserted into the fixing hole.
[0012] Furthermore, the fixing assembly also includes: a screw, a positioning cap, and a slot; the screw is threadedly connected inside the expansion sleeve; the positioning cap is coaxially fixedly connected to the front end of the screw; and the slot is formed inside the positioning cap.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] First, multiple hollow partition columns are bonded in an array in front of the bottom mortar layer. When the partition columns are impacted, they break first. During subsequent repairs, only the broken partition columns and the mortar layer and surface layer of the separated area need to be removed. There is no need for large-area removal, which reduces repair costs and makes repairs easier.
[0015] Secondly, a fixing component is added. An expansion sleeve is inserted through a hole drilled in the wall, and a positioning cap is used to lock the intersection of the fiber reinforcement of the reinforcing skeleton layer, thereby achieving mechanical fixing between the reinforcing skeleton layer and the wall. The connection is more secure, avoiding the risk of detachment that may occur with traditional bonding, and improving the overall resistance to settlement and deformation.
[0016] This invention utilizes an array of hollow partition columns bonded to the front of the bottom mortar layer, causing them to break preferentially upon impact. Repair only requires removing the damaged partition columns and the corresponding surface layer, reducing maintenance costs and facilitating repair. The mechanical structure strengthens the connection between the skeleton layer and the wall, avoiding the risk of detachment and improving the overall resistance to settlement and deformation. This invention represents a breakthrough in both structural performance and maintenance economy, providing a new technological paradigm for the sustainable development of green buildings.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0026] Example 1:
[0027] As attached Figure 1 To be continued Figure 6 As shown:
[0028] This utility model provides an easily repairable, high-strength decorative plaster structure, including a wall 1, an interface treatment layer 2, a reinforcing skeleton layer 3, a bottom mortar layer 4, a crack-resistant mesh layer 7, a surface layer 8, and easy-to-repair components; the interface treatment layer 2 is sprayed on the front surface of the wall 1; the reinforcing skeleton layer 3 is disposed in front of the interface treatment layer 2; the bottom mortar layer 4 is disposed in front of the interface treatment layer 2; the crack-resistant mesh layer 7 is disposed in front of the bottom mortar layer 4; the surface layer 8 is disposed inside and in front of the crack-resistant mesh layer 7; and the easy-to-repair components are disposed in front of the bottom mortar layer 4.
[0029] Among them, the reinforcing skeleton layer 3 is woven into a fiber mesh by interlacing high-strength fiber ribs with a diameter of three millimeters, and the overlap width of two adjacent reinforcing skeleton layers 3 is ≥100mm.
[0030] Among them, the crack-resistant mesh layer 7 is made of alkali-resistant glass fiber mesh, with a mesh size of 4mm×4mm and a unit area mass ≥160g / m². 2 The mesh fabric is laid horizontally with an overlap width of ≥100mm.
[0031] The components that facilitate repair include: a partition column 5 and a facial mortar layer 6; multiple partition columns 5 are provided, and the multiple partition columns 5 are dispersedly bonded to the front of the bottom mortar layer 4; the facial mortar layer 6 is provided in front of the bottom mortar layer 4.
[0032] The specific usage and function of this embodiment are as follows: During construction, first clean the surface of wall 1, using a high-pressure water gun to wash away dust and oil stains, and manually remove loose materials and other impurities to ensure that the surface of wall 1 is clean and flat; the interface treatment layer 2 is a special interface agent for walls, which is mixed with water and then evenly applied to the surface of wall 1 by roller or spray; after the interface agent dries and cures, the reinforcing skeleton layer 3 composed of fiber mesh is placed in front of the interface treatment layer 2, with an overlap width of ≥100mm between adjacent reinforcing skeleton layers 3, and the overlap is fixed with special adhesive; then the bottom is... For the construction of mortar layer 4, use a trowel to fill the mortar from bottom to top inside and in front of the mesh of reinforcing skeleton layer 3. The thickness of the bottom mortar layer 4 should be controlled at 5-7mm to ensure full bonding between the bottom mortar layer 4 and reinforcing skeleton layer 3, filling the gaps without any hollow areas or honeycomb phenomena. After the bottom mortar layer 4 has initially set, use adhesive to attach the partition columns 5 array to the front of the bottom mortar layer 4. The partition columns 5 are hollow structures, preferably made of lightweight, low-strength materials, such as foamed concrete columns or gypsum hollow columns. The surface is roughened to enhance the adhesion with the bottom mortar layer 4 and the facing mortar layer 6. The partition columns 5 can be arranged horizontally or crosswise. Set the plastering layer to a cross shape; then proceed with the construction of the surface mortar layer 6, with a thickness controlled at 7-10mm. The front surface of the surface mortar layer 6 should be flush with the front surface of the dividing column 5. Before the surface mortar layer 6 initially sets, lay the crack-resistant mesh fabric layer 7 flat on the surface of the base plaster layer. The crack-resistant mesh fabric layer 7 is made of alkali-resistant glass fiber mesh fabric, with the edge of the crack-resistant mesh fabric layer 7 extending 100mm beyond the construction area. Gently press it with a trowel to embed the mesh fabric into the surface mortar layer 6, ensuring that the crack-resistant mesh fabric layer 7 is tightly bonded to the surface mortar layer 6 without wrinkles or hollow areas. Avoid stretching the mesh fabric too tightly or too loosely during installation. Maintain a natural and flat state; finally, apply the surface layer 8 in front of the crack-resistant mesh layer 7. Different construction materials for the surface layer 8 can be selected according to the construction process design requirements. When the surface layer 8 cracks due to impact or other reasons, the partition column 5, as a "vulnerable unit", will crack first when impacted. During subsequent repair, only the damaged partition column 5, the surface mortar layer 6 of the separated area, and the surface layer 8 need to be removed. There is no need for large-area removal, which reduces the repair cost. At the same time, the array of partition columns 5 disperses the concentrated force to multiple units. Combined with the crack-resistant mesh layer 7, it can inhibit the chain propagation of cracks and greatly improve the impact resistance.
[0033] Example 2:
[0034] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown, it also includes a fixing component, which is set in front of the wall 1.
[0035] The fixing component includes a fixing hole 101 and an expansion sleeve 9; the fixing hole 101 is opened inside the wall 1; the expansion sleeve 9 is inserted into the fixing hole 101.
[0036] The fixing components also include: a screw 10, a positioning cap 11, and a slot 1101; the screw 10 is threadedly connected to the inside of the expansion sleeve 9; the positioning cap 11 is coaxially fixedly connected to the front end of the screw 10; and the slot 1101 is formed inside the positioning cap 11.
[0037] The specific usage and function of this embodiment are as follows: When laying the reinforcing skeleton layer 3, firstly, use tools such as an electric drill to drill holes in the wall 1 with a diameter of 6mm and a depth of 50mm. Then, insert the expansion sleeve 9. After that, screw the screw 10 and the positioning cap 11 into the expansion sleeve 9. The positioning cap 11 is made of plastic. Finally, insert the intersection of the reinforcing skeleton layer 3 into the slot 1101. The opening at the front of the slot 1101 is slightly smaller than the diameter of the fiber reinforcement that makes up the reinforcing skeleton layer 3. When inserting, use an interference fit connection to ensure that the fiber reinforcement of the reinforcing skeleton layer 3 can be inserted into the slot 1101 and will not easily fall off. The same method can be used to set the positioning cap 11 at multiple intersections of the fiber reinforcement of the reinforcing skeleton layer 3 to ensure that the reinforcing skeleton layer 3 can be stably fixed in front of the wall 1 and the interface treatment layer 2.
