Description

Technical Field

[0001] The utility model belongs to the field of existing building renovation, and in particular relates to an existing building insulation modular system. Background Art

[0002] Energy-saving renovation of existing buildings is one of the important ways to achieve energy conservation and emission reduction goals in the construction field. As a key technology in energy-saving renovation, exterior wall insulation technology can effectively improve the energy efficiency of buildings and reduce energy consumption. However, in practical applications, exterior wall insulation technology still faces some problems and challenges: First, the exterior wall insulation construction technology has high requirements. If the construction is improper, it may cause hollowing and cracking of the insulation layer, affecting the insulation effect and even causing subsequent problems such as leakage. Secondly, insulation materials may age and fall off over time, affecting the insulation effect and building safety. Therefore, it is necessary to take relevant measures to strengthen the connection structure between insulation materials and existing buildings, and at the same time, protect the insulation materials through protective measures.

[0003] On the other hand, with the increase in labor costs, on-site construction costs have increased year by year, and skilled industrial workers have gradually decreased. With the development of modern industrial technology, prefabricated construction refers to the transfer of a large number of on-site operations of traditional construction methods to factories, where building components and accessories (such as floors, wall panels, stairs, balconies, etc.) are processed and transported to the construction site for the construction and pouring of reinforced concrete, which is convenient and fast and can shorten the construction period. It can also reduce on-site construction and reduce on-site construction risks.

[0004] Insulation system installation is implemented on existing buildings (existing buildings are interpreted as buildings that are above ground and whose main structure is not to be continued and put into use) to achieve urban renewal and functional maintenance. General insulation systems, especially internal insulation, are divided into two types: one is the combination of insulation board and composite gypsum board; the other is the combination of insulation board and mortar. However, in the gypsum board form, the buried pipeline needs to be grooved, and in the mortar form, the mortar cannot hang on the insulation board.

[0005] Therefore, the utility model arises as the times require. Utility Model Content

[0017] Preferably, the number of the thermal insulation layers is a plurality of layers that are matched with each other.

[0018] Preferably, the outer covering layer is a shotcrete-formed cement base layer.

[0019] The technical effects of the above technical solution of the utility model come from one or more of the following combinations:

[0020] This solution directly fixes the insulation board on the existing wall, grooves can be cut on the insulation board for wiring, and then the outer covering layer is slurried through the structural mesh to form a structural carrier for the outer covering; this allows urban upgrades on existing structures, facilitates wiring, and is modularly assembled and easy to construct.

[0035] See also Figure 1 to Figure 5 This embodiment provides a modular system for thermal insulation of an existing building, including an existing wall 1, an insulation layer 2 and an outer covering layer 3. The existing wall 1 is constructed on the existing building; the insulation layer 2 includes an insulation board 21, a structural mesh board 22 and a connector 23; the structural mesh board 22 and the insulation layer 2 are installed on the existing wall 1 through the connector 23, and the insulation board 21 is located between the existing wall 1 and the structural mesh board 22; the outer covering layer 3 is formed on the structural mesh board 22, and the outer covering layer 3, the insulation board 21 and the existing wall 1 form a sandwich structure.

[0036] The "existing building" in the implementation is interpreted as: a building that is above ground and whose main structure is not to be continued and put into use. This embodiment has a wide range of applications and can be used as an urban renewal project for existing buildings.

[0037] The insulation board 21 is made of organic polymer material, preferably XPS material, which has certain structural strength and insulation function. In addition, shallow grooves can be opened on the insulation board 21 for wiring, which is convenient for the layout of pipelines (water pipes, wires and other water and electricity structure wiring) of the wall.

[0038] For details, please combine Figure 2 and Figure 5 A plurality of cable grooves 210 are provided on the side of the insulation board 21 facing away from the existing wall 1 , and mounting holes 2100 are opened in the cable grooves 210 . The connectors 23 connect the structural mesh plate 22 and the insulation board 21 to the existing wall 1 through the mounting holes 2100 .

[0039] Furthermore, the structural mesh panel 22 serves as a structural carrier of the outer covering layer 3, and a preferred implementation in this embodiment is a corrugated mesh panel. More preferably, a corrugated steel mesh panel is used. Specifically, the trough of the corrugated mesh panel is located in the cable trough 210, and is fixed to the insulation board 21 by the connector 23. The connector 23 is preferably a bolt or an expansion screw. When it is a bolt, the insulation board 21 and the corrugated steel mesh panel can be directly nailed to the existing wall 1. When selected, the end cap size of the bolt is slightly larger than the mesh of the corrugated steel mesh panel; when it is an expansion screw, first drill a hole in the existing wall 1, and then adjust the position of the mounting hole 2100 to correspond to the drilling position, and then install it. In practice, it is preferred to use low-cost bolts for interior wall insulation, and expansion screws can be used for exterior wall insulation.

[0040] The cable duct 210 serves as a pipeline layout and a structural reinforcement rib. Preferably, the cable duct 210 is a strip-shaped duct, which is arranged in the vertical direction. When the outer covering layer 3 is filled in the strip-shaped duct to form a filling area, the filling area is defined as the strip-shaped reinforcement rib 31 of the outer covering layer 3. Figure 3 and Figure 4 It can be seen that the trough of the corrugated mesh is buried in the cable groove 210 by the strip reinforcement rib 31, so the whole corrugated mesh is Figure 3 The visual effect shown is discontinuous.

[0041] In order to facilitate the transportation and installation of the insulation layer 2 in this embodiment, the number of insulation layers 2 is multiple and can be assembled together to achieve modular assembly. It can be assembled up and down, left and right, and after installation through the connecting piece 23, it is integrally sprayed to form the outer covering layer 3. Preferably, the outer covering layer 3 is a cement base formed by spraying.

[0042] Beneficial effects of this embodiment:

[0043] This solution directly fixes the insulation board 21 on the existing wall 1, grooves can be opened on the insulation board 21 for wiring, and then the outer covering layer 3 is slurried through the structural mesh plate 22 to form a structural carrier for the outer covering layer 3; this allows urban upgrades on existing structures, facilitates wiring, and is modularly assembled and easy to construct.

[0044] A corrugated mesh plate is used, and the trough position of the corrugated mesh plate corresponds to the cable groove 210 to facilitate the installation of the corrugated mesh plate. After the cables are arranged, the outer covering layer 3 is sprayed to form a stiffening rib in the cable groove 210.
