Description

Technical Field

[0001] The invention relates to the technical field of building walls, and in particular to an outdoor fish-scale pattern exterior wall structure and a construction method thereof. Background Art

[0002] With the development of social economy, people have put forward higher requirements for the improvement of production and living environment. The requirements for the exterior wall structure of buildings involve many aspects, which can roughly include material selection, structural design, waterproof treatment and fire safety.

[0003] In the prior art, in order to achieve good waterproofing, fire prevention and other beneficial effects at the same time, a multi-layer exterior wall structure is usually used. However, the multi-layer exterior wall structure will increase the design difficulty due to its own structural complexity in the design stage; secondly, a large amount of building materials will be required in the construction stage, which may have a certain impact on the environment, and the construction difficulty and cost of the multi-layer exterior wall structure are relatively high; finally, after the construction is completed, the maintenance and upkeep of the multi-layer exterior wall structure is relatively more complicated and difficult. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an outdoor fish-scale exterior wall structure, which has a relatively simple structural composition but can have good waterproof performance, fire resistance, crack resistance, etc., while also having good artistic decorative effects.

[0005] The present invention is achieved through the following technical solutions.

[0006] A kind of outdoor fish scale pattern exterior wall structure is arranged on the base wall, in which a waterproof mortar layer, a fish scale mesh layer and a mortar finishing layer are arranged in sequence from the base wall to the outside of the wall, and also includes a fixing part, which passes through the fish scale mesh layer and the waterproof mortar layer in sequence and is fixedly installed on the base wall to fix the fish scale mesh layer.

[0007] The fish scale net layer includes the fish scale net, which is named because of its appearance similar to the mesh structure of fish scales. It is usually an integrated convex-concave structure. The concave-convex structure of the fish scale net is usually designed with an inverted V-shaped convex part or an inverted W-shaped convex part or other similar structural shapes.

[0008] Incorporating a fish scale mesh layer into the exterior wall structure can utilize the special mesh structure of the fish scale mesh to disperse and transfer the load, thereby enhancing the bearing capacity of the wall and improving the overall stability and seismic performance of the building. At the same time, a water diversion trough structure is formed between several inverted V-shaped convexities and similar convexities set on the fish scale mesh. Therefore, when water contacts the wall, these water diversion trough structures can guide the direction of the water flow to prevent water from directly penetrating into the interior of the wall, thereby enhancing the waterproof performance of the wall. Finally, since the fish scale mesh is usually made of corrosion-resistant and high-temperature resistant materials, such as hot-dip galvanized steel, stainless steel or high-strength alloy steel, these materials have excellent heat resistance and corrosion resistance, and can maintain stable chemical properties and physical structures in high-temperature environments, ensuring that the fish scale mesh layer is not easy to melt or deform; and the scales of the fish scale mesh are usually closely arranged to form a protective layer, which helps to reduce the direct impact of high-temperature gas on the inside of the mesh body and protect the internal structure of the wall from high-temperature damage. Therefore, after adding a fish scale mesh layer to the exterior wall structure, it can ensure that the wall maintains a certain strength in a fire, thereby effectively preventing serious accidents such as building collapse in a fire. Therefore, after the fish scale mesh layer is introduced into the present invention, various exterior wall structure functions can be realized with a relatively simple structure, and the simple exterior wall structure also reduces the difficulty of its design, construction and subsequent maintenance.

[0009] As a further improvement of the present invention, the fish scale mesh layer includes a plurality of fish scale mesh blocks arranged in a flat manner, and a partition bar is provided between two adjacent fish scale mesh blocks.

[0010] As a further improvement of the present invention, the dividing strip is made of PVC material. PVC material has excellent weather resistance and can resist erosion by ultraviolet rays, high temperature and various pollutants. Therefore, the dividing strip made of PVC material can remain stable under various climatic conditions, and is not easy to age, fade or deform, thereby extending its service life. At the same time, the dividing strip made of PVC material is usually prefabricated strips, which are easy and quick to install. In terms of installation method, it can be directly fixed on the wall without complicated construction technology and additional tools. This simplicity of construction not only improves construction efficiency, but also reduces construction costs.

[0011] As a further improvement of the present invention, a first distance is formed between the edge of the fish scale mesh layer and the edge of the adjacent external wall structure, and the first distance is at least 30 mm.

[0012] This structure can prevent the edges of the fish scale mesh layer from warping up during long-term use, which can cause the fish scale mesh layer to gradually peel off from the exterior wall structure. At the same time, this structure can prevent the fish scale mesh from being difficult to align at the corners of the exterior wall structure, thereby ensuring smooth connection of the corner structure.

[0013] As a further improvement of the present invention, the fixing member is a screw. The screw can be applied to base walls of various materials, such as concrete, brick walls, gypsum boards, etc., and the screw can ensure a stable fixing effect on the corresponding base wall. Compared with other fixing members such as expansion screws that need to be pre-drilled or nails that need to be hammered multiple times, the installation process of the screw is simpler. And during the installation process, if a slight deviation in the position is found, the thread design of the screw allows it to be adjusted to a certain extent to ensure accurate fixation of the fish scale mesh layer.

[0014] As a further improvement of the present invention, the plurality of screws include at least four screws for respectively fixing the four corners of the fish scale mesh block to the base wall.

[0015] In a second aspect, the present invention provides an outdoor fish scale pattern exterior wall structure construction method, which is used to construct any one of the above-mentioned outdoor fish scale pattern exterior wall structures, and comprises the following steps: S1. Correcting the base wall to keep the construction surface of the base wall flat; S2. Applying waterproof mortar on the construction surface to form a waterproof mortar layer; S3. Pre-laying a fish scale mesh layer on the waterproof mortar layer, and driving the fixing part to pass through the fish scale mesh layer and the waterproof mortar layer in sequence until it is fixed on the base wall; S4. Applying mortar on the fish scale mesh layer to form a mortar finishing layer on the surface of the exterior wall structure.

[0016] As a further improvement of the present invention, when the base walls of different materials are connected, in S1, a galvanized steel mesh is hung on the junction of the base walls of different materials, and cement mortar mixed with an interface agent is used to maintain the junction.

[0017] As a further improvement of the present invention, when the fish scale mesh layer is composed of a plurality of fish scale mesh blocks, in S3, before the pre-laying, a plurality of pre-laying intervals are separated on the waterproof mortar layer, and then the size of the fish scale mesh blocks is cut and corrected to adapt to the pre-laying intervals; after the fixing work of the fixing parts is completed, a dividing strip is used to fill the gap between two adjacent fish scale mesh blocks.

[0018] As a further improvement of the present invention, in S3, during the pre-laying, a first spacing is left between the edge of the fish scale mesh layer and the edge of the exterior wall structure; in S4, the mortar is used to fill the gap in the exterior wall structure caused by the first spacing, and the mortar is used to smooth out the gaps at the corners of the exterior wall structure.

[0019] The beneficial effects of the present invention include: (1) Introducing the fish scale mesh layer into the exterior wall structure can significantly improve the performance of the exterior wall structure in terms of crack resistance, fire resistance, and prevention of exterior wall leakage. At the same time, due to the concave and convex surface structure of the fish scale mesh structure, it can fit closely with other layers such as the waterproof mortar layer, and obtain better fish scale mesh adhesion, making the overall exterior wall structure strong and having a long service life; (2) Under the exterior wall structure of the present invention, after the fish scale mesh layer is introduced, multiple beneficial effects can be achieved with a relatively simple structure, and the simple exterior wall structure has the characteristics of simple design, simple construction, and convenient cleaning and maintenance; (3) After the fish scale mesh layer is introduced into the exterior wall structure, the artistic decorative effect can be perfectly combined with the environment according to the site environment and project characteristics, thereby improving the aesthetics of the wall.

The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions.

[0024] Embodiment 1: In this embodiment, an outdoor fish-scale exterior wall structure is disclosed.

[0025] Figure 1The structure shown is the cross-sectional view of the exterior wall structure and the base wall A in this embodiment. From the base wall A to the outside of the wall, the exterior wall structure is sequentially provided with a waterproof mortar layer 1, a fish scale mesh layer 2 and a mortar finishing layer 3, wherein the fish scale mesh layer 2 is fixed to the base wall A by a fixing member 4. The fixing member 4 used in this embodiment is a screw, which passes through the fish scale mesh layer 2 and the waterproof mortar layer 1 in sequence and is finally fixed to the base wall A.

[0026] Figure 2 The structure of the fish scale mesh layer 2 when the exterior wall structure of this embodiment is observed from the front is shown. The fish scale mesh layer 2 is composed of a total of six fish scale mesh blocks 201 laid flat, each of which is provided with a plurality of inverted V-shaped protrusions 201a, and a water diversion trough structure 201b is formed between the plurality of inverted V-shaped protrusions. This enables these water diversion trough structures 201b to guide the direction of water flow when moisture contacts the wall surface, thereby preventing moisture from directly penetrating into the interior of the wall, thereby enhancing the waterproof performance of the wall surface. A 20 mm wide seam is formed between two adjacent fish scale mesh blocks 201, and a dividing strip 5 made of PVC material with a width of 20 mm is used to fill each seam. Since each fish scale mesh block 201 in this embodiment is a rectangular structure, six screws are used to fix the fish scale mesh block 201, four of which are respectively provided at the four corners of the fish scale mesh block 201, and the remaining two are provided at the midpoint of the long side of the fish scale mesh block 201. At the same time, Figure 1 As shown in FIG. 1 , a first distance L1 is formed between the edge of the overall fish scale mesh layer 2 and the edge of the external wall structure. In this embodiment, the size of the first distance L1 is 30 mm.

[0027] Embodiment 2: In this embodiment, a construction method of an outdoor fish scale pattern exterior wall structure shown in Embodiment 1 is disclosed. The mortar raw materials used in this embodiment are all common commercial mortars, and the waterproof mortar is made by adding a water reducing agent and a retarder to the common commercial mortar, which is only a mortar with waterproof function.

[0028] The construction method specifically includes the following steps: S1. Perform preliminary treatment on the base wall A. First, clear the construction surface of the base wall A for subsequent construction, including cleaning the concrete slurry and the plywood on the original structure, and avoid sharp protrusions, such as nails and wires, to prevent puncturing the later wall plastering, causing cracks and loss of visual effect. Secondly, the mortar joints on the base wall A are hooked and plastered tightly, and the holes such as scaffolding eyes are blocked and compacted with expanded fine stone concrete to prevent leakage. Finally, lay out the base wall A, check the vertical flatness of the large wall surface, the straightness of the large sun angle, the straightness of the external window line, etc., and deal with any problems found.

[0029] If the materials of the connected base walls A are different, a galvanized steel mesh with a size of 10 mm × 10 mm is hung at the junction of the base walls A, and watered one day in advance to moisten them, and then cement mortar mixed with an interface agent is used to spray grout comprehensively and evenly, and then watered and cured after spraying, and the curing time is not less than 3 days, and in this embodiment, it is 4 days; S2. Apply waterproof mortar to the construction surface of the base wall A to form a waterproof mortar layer 1.

[0030] The waterproof mortar is made of mortar mixed with a water reducing agent, and a retarder is added to ensure the workability and fluidity of the mortar. After the coating is completed, the thickness of the waterproof mortar layer 1 needs to maintain a uniform thickness of about 20 mm. The coating process is carried out from top to bottom. The vertical deviation of the waterproof mortar layer 1 does not exceed 4 mm, and the flatness does not exceed 4 mm. Among them, for the part of the waterproof mortar layer 1 with a thickness exceeding 35 mm, a steel wire mesh is added. In the present invention, in order to ensure that the waterproof mortar layer 1 is firmly bonded to the fish scale mesh block 201, the surface of the waterproof mortar layer 1 does not require calendering, but it is preferred to maintain a rough surface, but there should be no sharp protrusions that may damage the fish scale mesh block 201.

[0031] S3. According to the size of the wall, the positions of the six fish scale mesh blocks 201 are arranged in the drawing software to ensure that the gap width between two adjacent fish scale mesh blocks 201 is 20 mm, and a first spacing L1 of 30 mm is left between the edge of the fish scale mesh layer 2 and the edge of the external wall structure. Then, the size of the fish scale mesh blocks 201 is trimmed and corrected according to the design drawings.

[0032] When the fish scale mesh block 201 is pre-laid, first establish the horizontal and vertical reference lines, and draw a vertical reference line on both sides of the wall, with no more than 10 m in the middle, and then draw lines on the wall to be pasted according to the reference lines, and pop out the arrangement position lines or position control lines of the fish scale mesh block 201. To control the verticality and flatness of the fish scale mesh layer 2 as a whole. Large sun angles require hanging reference steel wires, laying out the lines according to the modulus of the fish scale mesh block 201, and using infrared rays for horizontal and vertical line laying construction. After the pre-laying is completed, the fish scale mesh block 201 is fixed with screws and pressed into the waterproof mortar layer 1. In this embodiment, six screws are provided on each fish scale mesh block 201. After the fixing is completed, ensure that the fish scale mesh block 201 is not loose; strictly control the flatness and verticality of the mesh surface of the fish scale mesh block 201 and the height difference between the adjacent fish scale mesh blocks 201, and use a ruler with a length of not less than 2m to flatten and check. It is strictly forbidden to bend or hit the fish scale mesh block 201 with heavy objects during construction. After the fish scale mesh block 201 is fixed, a PVC dividing strip 5 is embedded in the split seam to complete the filling. The width of the dividing strip 5 is 20 mm.

[0033] S4. A layer of mortar is applied on the surface of the fish scale mesh layer 2 to form a mortar surface layer 3. The mortar is also needed to fill the gaps in the exterior wall structure caused by the first spacing L1 in S3, and the mortar is used to apply gaps at the corners of the exterior wall structure.

[0034] Before the mortar is initially set, the excess mortar on the fish scale mesh layer 2 is swept with a broom to expose the fish scale mesh layer 2. After the mortar finishing layer 3 reaches a certain strength, a water gun is used to spray the second time. The spraying should be carried out in sections to wash away the cement slurry on the surface of the fish scale mesh layer 2, revealing the fish scale mesh blocks 201 and presenting the fish scale pattern effect.

[0035] After the final construction is completed and passed the overall inspection, it will be reported to the supervision unit and the construction unit for acceptance.

[0036] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned implementation cases, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned implementation cases, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
