Description

TECHNICAL FIELD

[0001] The present application relates to a building smoke exhaust component, in particular to a prefabricated plate of a building smoke flue, and further relates to a smoke flue composed of prefabricated plates of a building smoke flue, and further relates to a mounting method of the smoke flue. BACKGROUND

[0002] The existing high-rise buildings, especially the kitchens of residential buildings, are all provided with flues. Generally, the flues are rectangular columnar bodies, and are often installed at the corners of two wall bodies. The traditional flues are all made of bricks, but the wall thickness and strength thereof cannot meet the requirements, and the quality is poor. With continuous research and development of personnel in the later period, the flues used by most construction companies at present are all made through mechanization, and the flues made through the method have the advantages of good quality and high production efficiency.

[0003] At present, various types of building smoke exhaust and air supply and exhaust pipelines are used, for example, the smoke flues of residential kitchen and bathroom, which adopt the following construction process: factory feeding → processing into finished products → loading → transportation → unloading → vertical transportation → installation → plastering → filling of reserved hole gaps and other necessary construction processes. However, since the height between floors needs to be between 2.8-3 meters, the height of the general flues is also within the interval, and the problems of the product and the construction process are as follows: 1. Since the product is heavy, the labor intensity, safety risk and cost of the construction processes such as carrying, loading, unloading and installation are high, and the flue wall is easy to be damaged; 2. The smoke flue is stacked together from top to bottom on each floor, and a support needs to be made every several floors to reduce the load bearing of the bottom floor, but the support has the hidden danger of corrosion.

[0004] In the prior art, a kind of assembled flue with application number 201410074333.9 is disclosed, which is assembled into a columnar flue by vertically splicing two L-shaped flue plates and fixedly connecting them through buckles at the connecting positions, and then the flue is installed by inserting the joints of the columnar flues. Although the assembled flue reduces the self-weight of the flue to some extent and is more convenient to carry and transport, the assembled flue still has the following problems: 1. The assembly process is relatively complicated, the structure is relatively complex, and the cost is high; 2. The sealing quality of the hole position seriously affects the waterproof ability of the kitchen and bathroom after the flue is installed, and since the flue and the exhaust flue are often arranged at the corners, the sealing quality of the two sides close to the wall cannot be guaranteed, which causes great hidden dangers to the kitchen and bathroom; 3. The gap treatment after the flue is assembled is difficult, and quality problems such as smoke leakage and oil leakage are easy to occur, and there are many quality control points in the installation process.

[0005] With the improvement of the flue fireproof requirement, some flues are made of refractory material, which enhances the fireproof performance and reduces the weight of the flue itself. However, it is found during the installation process that the refractory material is difficult to be combined with the traditional cement mortar by relying on the self viscosity of the cement mortar, which brings great problems to the surface treatment after installation. SUMMARY

[0006] The purpose of the present application is to provide a prefabricated panel of flue, which is made into a semi-finished product, and then the subsequent process is implemented on site to complete the finished product after installation, so that the prefabricated panel of flue has good integrity, that is, saves materials and energy, and does not leak smoke and gas. On the basis of this purpose, another purpose of the present application is to provide a flue composed of prefabricated panels of flue, which are combined with the reserved flue passage in the building to jointly constitute or individually constitute the flue. On the basis of this purpose, still another purpose of the present application is to provide a method for installing the flue composed of prefabricated panels of flue.

[0007] The purpose of the present application is achieved as follows: the prefabricated panel of flue comprises at least one panel, a plurality of support grooves are arranged on the outer surface of the panel to strengthen the connection between the adhesive layer and the panel, and an adhesive layer is applied on the outer surface of the panel to form a composite panel.

[0008] The panel is vertically arranged, and a support plate is arranged at intervals on the exposed surface at the bottom of the outer surface of the panel.

[0009] The panel is obliquely arranged, and a support plate is arranged at intervals on the exposed surface at the bottom of the outer surface of the panel.

[0010] The support grooves are convex or concave on the outer surface of the prefabricated panel; the support grooves are arranged in parallel from top to bottom on the outer surface of the prefabricated panel.

[0011] The prefabricated panel is formed by butting two panels to form an L-shaped panel; the prefabricated panel is formed by butting three panels to form a U-shaped panel; and the prefabricated panel is formed by butting four panels to form a cavity body which is closed on four sides and open at the top and bottom.

[0012] The flue composed of prefabricated panels of flue comprises a reserved passage formed by opening from the lowermost floor to the top floor in the building, the reserved passage forms a reserved opening which is equal in size and penetrates up and down on each floor except the lowermost floor; and the prefabricated panel, which is fixed in the reserved passage between adjacent upper and lower floors in the building, and the wall of the reserved passage jointly constitute a flue passage; the prefabricated panel comprises at least one panel, a plurality of support grooves are arranged on the outer surface of the panel to strengthen the connection between the adhesive layer and the panel, and an adhesive layer is applied on the outer surface of the prefabricated panel.

[0013] Due to the above technical scheme, the flue gas air passage made by the application can be prefabricated in the factory, and the prefabricated plate with light weight is transported to the construction site of the building to be installed. When the wall surface is coated with silicate cement mortar, the attached layer is coated on the prefabricated plate at the same time. The attached layer and the panel are inlaid together through the supporting groove, which reduces a process, reduces the heavy labor and loss in the transportation and lifting process, and also can be prefabricated in the factory by using a mold. The prefabricated plate is placed in the mold to coat the attached layer to directly make the composite plate, which is transported to the construction site of the building to be installed. The weight of the prefabricated plate is much lighter than that of the silicate cement mortar flue gas air passage.

[0014] Secondly, the supporting plate is arranged at intervals between the exposed surfaces at the bottom of the prefabricated plate. When the flue gas air passage is vertical, the bottom end of the last flue gas air passage is located at the top end of the next flue gas air passage, so that the weight is all borne by the bottom floor, which is easy to cause structural bearing problems. The reinforcement is easy to rust, so the prefabricated plate is located on the floor through the supporting plate, which ensures the verticality of the flue gas air passage, and the weight is borne by each layer. The supporting plate is arranged at intervals to fill the gap between the flue gas air passage and the floor with concrete through the intervals, so that each floor is complete and has no leakage points.

[0015] The connecting layer is coated on the inner wall of the reserved passage, and the recessed clamping groove is prefabricated at both ends of the connecting layer. The protruding hooks matched with the recessed groove are prefabricated at both ends of the prefabricated plate. In this way, the weight of the flue gas air passage can be borne by each floor, and the installation is very convenient. The L-shaped or U-shaped flue gas air passage can be hung in the recessed or protruding clamping groove to complete the installation.

[0033] DETAILED DESCRIPTION: The present application is not limited by the following examples, and the specific implementation can be determined according to the technical solution of the present application and the actual situation.

[0034] Example 1: As shown in the drawings, the prefabricated plate of the flue comprises at least one panel 1, and a plurality of support grooves 5 are arranged on the outer surface of the panel 1 to strengthen the connection between the attached layer and the panel 1. An attached layer 9 is applied to the outer surface of the panel 1, and the attached layer 9 and the panel 1 form a composite panel. Figures 1-15 The plurality of support grooves 5 are arranged on the outer surface of the panel 1 from top to bottom; further, the plurality of support grooves 5 are arranged on the outer surface of the panel 1 in parallel from top to bottom.

[0035]

[0036] ​The support groove 5 protrudes outwardly from the outer surface of the panel 1; the support groove 5 protruding outwardly from the outer surface of the panel 1 comprises a body, and a groove is formed between the body and the outer surface of the panel 1. When the adhesive layer 9 is applied to the outer surface of the panel 1, a part of the adhesive layer 9 will enter the groove. After the adhesive layer 9 is dried, the adhesive layer 9 entering the groove forms a structure hanging in the groove, thereby preventing the adhesive layer 9 from moving outwardly and downwardly. The structure and the viscosity of the adhesive layer 9 itself can achieve firm combination of the panel 1 and the adhesive layer 9. This connecting structure is more suitable for the panel 1 made of a material with a smooth surface and difficult to combine with the adhesive layer 9.

[0037] The support groove 5 is recessed in the outer surface of the panel 1; the support groove 5 recessed in the outer surface of the panel 1 comprises an inverted L-shaped groove opened in the panel 1 and a slot opened on the outer surface of the panel 1. This structure is not shown in the drawings. Compared with the structure of the support groove 5 protruding outwardly from the panel 1, this structure is more difficult to process and affects the overall strength of the panel 1. Therefore, this structure is not the optimal solution.

[0038] A plurality of blocks are fixed on the outer surface of the panel 1 between every two adjacent support grooves 5, and a groove is opened on the upper end surface of the block. The specific structure of the block is not shown in the drawings. The block mainly serves to supplement the support groove 5, and the addition of the block can further enhance the combination strength of the adhesive layer 9 and the panel 1.

[0039] The prefabricated panel is formed by butt joint of two panels 1 to form an L-shaped panel; the prefabricated panel is formed by butt joint of three panels 1 to form a U-shaped panel; and the prefabricated panel is formed by butt joint of four panels 1 to form a cavity body with a closed periphery and an open top and bottom.

[0040] The panel 1 is vertically arranged, and the support plate 6 is arranged at the exposed surface at the bottom of the outer surface of the panel 1.

[0041] The panel 1 is arranged obliquely, and the support plate 6 is arranged at the exposed surface at the bottom of the outer surface of the panel 1.
