Description

Technical Field

[0001] The invention relates to the field of building wall exterior windows, and in particular to an embedded ultra-low energy consumption building exterior window installation device. Background Art

[0002] In traditional building construction, window frames are usually installed at the designed position through reserved openings during the decoration stage. Due to the lack of connection between different processes, the construction quality cannot be guaranteed, and the reserved opening method for installing window frames will cause many quality risks.

[0003] The existing external windows of ultra-low energy consumption buildings are externally mounted, and the auxiliary frames and window frames are directly connected to the outside of the concrete wall with connecting fixtures. With this setting method, most of the construction requires workers to work outdoors, which greatly increases the safety hazards of construction workers. In addition, when the external mounting method is adopted, if the fixings of the external windows fall off during use, the passive windows are at risk of falling and injuring people at any time. When the external windows need to be repaired or reinstalled, most of the work can only be done from the outdoors, and the insulation materials around the outdoor openings must be removed at the same time. The later replacement and repair costs of the external windows are much greater than their installation costs, which increases the difficulty of maintenance.

[0004] The embedded pre-buried installation process has the advantages of simple construction, strong thermal insulation performance and good air tightness, which has positive significance for promoting the promotion and development of ultra-low buildings. Although the existing embedded building exterior window installation process has advantages such as good thermal insulation performance, the traditional process is the strip sticking method or the point frame method + post-expansion anchor connection, the exterior wall insulation board is thick, the construction speed is slow, the flame retardant performance is poor, and the air tightness is poor. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an embedded ultra-low energy consumption building exterior window installation device, which has good air tightness, flame retardancy and thermal insulation properties.

[0006] The present invention achieves the above technical objectives through the following technical means.

[0007] A built-in ultra-low energy consumption building exterior window installation device comprises a window frame, a prefabricated sandwich insulation body, an energy-saving auxiliary frame and an exterior window glass; the exterior window glass is installed on the window frame, one end of the energy-saving auxiliary frame is arranged in a concrete structure layer, and the other end of the energy-saving auxiliary frame is connected to the window frame; the prefabricated sandwich insulation body is arranged on the outside of the concrete structure layer and the energy-saving auxiliary frame.

[0008] In the above scheme, the window frame and the energy-saving auxiliary frame are bonded by polyurethane foam, and a steel lining is arranged in the energy-saving auxiliary frame; the window frame, polyurethane foam and energy-saving auxiliary frame are connected by expansion screws, and the ends of the expansion screws are placed in the steel lining.

[0009] In the above scheme, the energy-saving auxiliary frame is arranged at the recess of the concrete structure layer, and the bottom end of the energy-saving auxiliary frame is connected to the concrete structure layer through claw nails, and the claw nails include expansion screws and figure-eight claws; wherein, the expansion screw tip is connected to the energy-saving auxiliary frame upward, the figure-eight claw is installed on the expansion screw, and the figure-eight claw is placed in the concrete structure layer.

[0010] In the above scheme, a modified graphite insulation board is arranged in the energy-saving auxiliary frame near the concrete structural layer side, the modified graphite insulation board is bonded or detachably connected to the concrete structural layer and the energy-saving auxiliary frame, and the outer side of the modified graphite insulation board is coated with cement mortar.

[0011] In the above solution, heat-insulating PE foam is arranged in the window frame.

[0012] In the above scheme, an insulation layer is arranged above the prefabricated sandwich insulation body, and a window sill is arranged above the insulation layer, and the window sill has a certain slope.

[0013] In the above scheme, the insulation layer includes a 5% slope cement-based inorganic insulation mortar and a glass fiber mesh cloth pressed inside a special adhesive waterproof and crack-resistant mortar for exterior walls; wherein the glass fiber mesh cloth pressed inside the special adhesive waterproof and crack-resistant mortar for exterior walls is in contact with the window sill, and a sealing belt is arranged between the window sill and the insulation layer; a polyurethane foaming agent is arranged between the insulation layer and the prefabricated sandwich insulation body.

[0014] In the above scheme, the prefabricated sandwich insulation body and the insulation layer are provided with JS waterproof coating and waterproof breathable membrane on the contact side with the energy-saving auxiliary frame.

[0015] In the above scheme, the prefabricated sandwich insulation body includes a protective layer, anti-cracking mortar, a concrete outer page board, a rigid foam polyurethane sandwich insulation and a reinforced concrete wall from the outside to the inside; wherein the reinforced concrete wall and the concrete structural layer are an integrated structure.

[0016] In the above solution, the outer window glass is a three-glass two-cavity built-in roller blind.

[0017] The present invention has the following advantages:

[0018] 1. The embedded structure of the present invention can provide higher fixing strength and stability through the combined use of the figure-eight grip and the expansion screws, ensuring that the energy-saving auxiliary frame is firmly embedded in the concrete structure layer and is not easy to loosen or fall off. This design is more stable and enhances the safety and stability of the overall structure.

[0019] 2. In order to solve the problems of thick exterior wall insulation boards, poor flame retardancy and poor air tightness, the exterior window structure of ultra-low energy consumption buildings adopts a prefabricated sandwich insulation system with rigid foam polyurethane sandwich insulation inside. The thickness of the insulation layer is reduced and this material is flame retardant and fireproof. The system can provide good air tightness, reduce heat loss caused by air leakage, and prevent cold wind from penetrating into the room.

[0020] 3. The present invention adopts a polyurethane energy-saving auxiliary frame. The polyurethane material has excellent thermal insulation performance, can effectively reduce heat conduction, improve the thermal insulation effect of the building, and eliminate thermal bridges between the external windows and the wall. A steel lining is arranged inside the energy-saving auxiliary frame to enhance the structural strength of the auxiliary frame and improve the overall rigidity and stability.

[0021] 4. The present invention adopts heat-insulating PE foam and polyurethane foaming agent. The polyurethane foaming agent can be firmly bonded with various substrates to form a seamless insulation layer, reduce the cold bridge effect, and improve the insulation effect. Both materials are beneficial to thermal insulation, can effectively reduce heat loss, and reduce energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS
