Problems solved by technology

Therefore, whether it is cast-in-place installation of concrete-supported cantilever beams or prefabricated installation of concrete-supported cantilever beams, the construction is very inconvenient
[0019] 2) When applying the supported external thermal insulation composite wall in the existing building energy-saving renovation project, the number of planting bars is large, and it is difficult to integrate the old and new concrete, which is not easy to ensure the quality of the project, and the construction is inconvenient
[0020] 2. The cast-in-place concrete support cantilever beam is inconvenient to connect with the steel structure. If it is prefabricated, two steel plates at the front end and the rear end are required. The steel consumption is large and the prefabrication quantity is large
The rigidity of the tox nails and the plastic connecting bridge is not good, especially when the benzene board shrinks in case of a fire, the plastic of the tox nails and the plastic connecting bridge also melts quickly, and the external plastering protective layer is still in danger of falling off
[0024] This shows that the current energy-saving and thermal insulation wall technologies generally do not solve the safety problem of the outer protective layer.
[0025] 3. At present, the technology of energy-saving and thermal insulation wall curtain wall decoration and installation has not been solved, resulting in poor fire prevention of curtain wall decoration, such as the CCTV fire, which is the burning of the insulation layer in the curtain wall

Embodiment 1

[0067] Embodiment one: see Figure 1 to Figure 8 , Figure 15, a kind of supporting external thermal insulation composite wall of the present embodiment is composed of base wall 1, steel truss cantilever beams 1-5, thermal insulation layer 3, mesh tensile material 5, steel bar 4, protective layer 8, It is composed of internally and externally connected steel wires 9 and a main building structure 10; the base wall 1 is a concrete wall, a load-bearing masonry wall, a non-load-bearing lightweight masonry filling wall or a wall made of steel and wood or bamboo and wood; the insulation layer 3 It is a polymer insulation material or a plant straw board or a paper honeycomb board or an inorganic insulation material; the steel bar 4 includes a vertical steel bar 4-1 and a horizontal steel bar 4-2; the mesh tensile material 5 is an alkali-resistant mesh cloth 5 -1 or metal mesh 5-2 or bamboo reinforcement mesh 5-3; the protective layer 8 is cement mortar or fine stone concrete, or mod...

Embodiment 2

[0078] Embodiment two: see Figure 9 The difference between the present embodiment and the first embodiment is that the reinforcing bars 4 of the present embodiment are parallel double reinforcing bars, and the parallel reinforcing bars 4 are connected with the outer ends of the steel truss cantilever beams 1-5, and between the parallel reinforcing bars 4, Set steel bars to form a small truss structure or set steel plates or partially welded block-shaped steel to form a reinforced structure with parallel double steel bars, which is a supported external thermal insulation composite wall.

[0079] When installing anti-theft fences and heavy decorations on doors and windows, it is necessary to install steel plates on the steel bars of doors and windows so as to connect iron parts and steel plates for fixing. Therefore, the doors and windows are equipped with double steel bars, and steel plates are installed at the required positions between the double steel bars, so that the anti...

Embodiment 3

[0080] Embodiment three: see Figure 9 The difference between this embodiment and embodiment one or two is that the present embodiment welds steel plates at the outer ends of steel truss cantilever beams 1-5, and installs the shaped steel keel for hanging objects on external walls such as decorative curtain walls, billboards or solar photovoltaic panels. Connect with steel truss cantilever beams 1-5 outer end steel plates or / and with steel plates or block shaped steel on parallel steel bars 4 to form a supported external wall external thermal insulation composite wall and install decorative curtain walls, billboards or The structure of external wall hangings such as solar photovoltaic panels.

[0081] This embodiment is to solve the fire prevention problem of the composite thermal insulation wall curtain wall described in the background technology. In the cavity between the decorative curtain wall and the protective layer, fire isolation belts should also be set at a certain ...

Abstract

The invention discloses an exterior wall external insulation composite wall provided with a support, and relates to a thermal insulation composite wall of a building. The invention aims at solving the problem of inconvenience for construction of a concrete support cantilever beam of a public exterior wall external insulation composite wall provided with the support. The exterior wall external insulation composite wall is characterized in that the inner end of a steel truss cantilever beam and a building main body structure or a substrate wall are fixed, an insulating layer is located outside the substrate wall, and a reinforcing steel bar is arranged outside the insulating layer; the reinforcing steel bar is connected with the steel truss cantilever beam, and a metal net and the reinforcing steel rib are fixed; the reinforcing steel bar and the metal net are located in a protecting layer, and the protecting layer is connected with the insulating layer; and the reinforcing steel bar and the building main body structure are fixed by internally and externally pulled steel wires. According to the invention, the steel truss cantilever beam can be arranged in the concrete through embedding a steel plate or planting the bar, a concrete template is not destroyed, installation labor and consumption of welding materials can be saved, the construction is convenient, the cost of construction is reduced, the energy-saving thermal insulation effect of the wall is increased, and obstacles of applications of the conventional building energy efficiency reconstruction projects are cleared.

Description

technical field [0001] The invention relates to an external thermal insulation composite wall body of a building, in particular to a supported external thermal insulation composite wall body of an external wall. Background technique [0002] The problems of wall energy-saving and thermal insulation technology not only affect the effectiveness of building energy conservation and the construction of a low-carbon society, but also affect the safety of people's lives and property. The fire broke out. Not long ago, the tragedy of the high-level fire in Jing'an District, Shanghai, which shocked the world on November 15, 2010, happened! Then, in the early hours of the first day of the Lunar New Year in 2011, the insulation layer of Shenyang Dynasty Wanxin International Building, the tallest in Northeast China, was burned due to fireworks and firecrackers. The fire caused heavy losses to the society. The reason why wall energy-saving and thermal insulation technology keeps fires is...
