Abstract

The utility model relates to a novel building thermal-insulation and heat-preservation external wall which comprises a light curtain wall board fixed on the outer side of a building external wall viaa connecting piece. The novel building thermal-insulation and heat-preservation external wall is characterized in that the connecting piece adopts a U-shaped curtain wall metal fixing part, one side of the U-shaped curtain wall metal fixing part is fixed on the outer side surface of the building external wall through an expansion screw for an insulation cold bridge, and an insulation rigid plasticor wooden packing block is lined between the U-shaped curtain wall metal fixing part and the building external wall; and the other side of the U-shaped curtain wall metal fixing part is connected with the inner side of the light curtain wall board through a self-tapping screw. The utility model avoids the problem that the curtain wall metal fixing part and the building external wall form a hot cold bridge, enhances the heat-preservation and thermal-insulation performance of the building external wall, and is in favor of reducing energy consumption of heating or refrigerating for the building,thereby being easy for popularization and application.

Description

Novel building heat insulation exterior wall

Technical field

The utility model relates to a kind of heat insulation structure of building construction, specifically is a kind of novel building heat insulation exterior wall.

Background technology

Along with developing rapidly of domestic economy, and global energy is in short supply, people strengthen day by day to energy-conserving and environment-protective consciousness, for residential building, office building, office premises, the hotel, the outer body of wall of building constructions such as commercial building market, carry out the thermal insulation construction and become a kind of energy-saving and thermal insulating pattern that current engineering circle is generally acknowledged, when especially under high degree of comfort low energy consumption heating (refrigeration) adds, serving back the new wind mode of total replacement and in China's building trade, being adopted by a part of construction work, it adopts a large amount of decorative curtain walls, and the metal fixing (be commonly called as and be keel) that curtain wall is installed does not possess adiabatic function, it and external wall have formed hot cold bridge, become the passage of architecture indoor and outdoor energy exchange, the thermal and insulating performance that it has reduced the external wall system has increased the consumption of the building and heating or the required energy that freezes.

Summary of the invention

The purpose of this utility model provides a kind of novel building heat insulation exterior wall, do not possess adiabatic function with the metal fixing (being commonly called as is keel) that solves the installation curtain wall that prior art exists, it and external wall have formed hot cold bridge, become the passage of architecture indoor and outdoor energy exchange, the thermal and insulating performance that it has reduced the external wall system has increased the problem of the consumption of the building and heating or the required energy that freezes.

The purpose of this utility model realizes by following technical scheme: comprise the lightweight curtain wall panel that is fixed on the external wall outside by connector, it is characterized in that: described connector is a U type curtain wall metal fixing, one side of this U type curtain wall metal fixing is fixed on the lateral surface of described external wall with the bloated riveting screw of disconnected hot cold bridge, adiabatic duroplasts of liner or wooden cushion block between this U type curtain wall metal fixing and external wall; The opposite side of this U type curtain wall metal fixing is connected with the inboard of described lightweight curtain wall panel with self-tapping screw.

The utility model adopts technique scheme, its easy construction, be easy to guarantee workmanship, can avoid curtain wall metalwork and external wall to form hot cold bridge, and improve the thermal and insulating performance of external wall system, help saving building and heating or the needed energy that freezes, be easy to promote the use of.

Description of drawings

Fig. 1 is a sectional structure schematic diagram of the present utility model.

The specific embodiment

As shown in Figure 1, the utility model is fixed on external wall 8 outsides by U type curtain wall metal fixing 1 with lightweight curtain wall panel 5.One side of this U type curtain wall metal fixing 1 is fixed on the lateral surface of described external wall 8 with the bloated riveting screw 2 of disconnected hot cold bridge, adiabatic duroplasts of liner or wooden cushion block 3 between this U type curtain wall metal fixing 1 and external wall 8; The opposite side of this U type curtain wall metal fixing 1 is connected with the inboard of described lightweight curtain wall panel 5 with self-tapping screw 6.

Apply one deck insulating foam layer 4 on described external wall 8 lateral surfaces, this insulating foam layer 4 wraps the part of described U type curtain wall metal fixing 1 near external wall 8; Between this insulating foam layer 4 and described lightweight curtain wall panel 5, leave an air heat-insulation layer 7.

The job practices of the utility model when using is:

1, at first the bloated riveting screw 2 of the disconnected hot cold bridge of U type curtain wall metal fixing 1 usefulness is fixed on external wall 8 lateral surfaces, adiabatic duroplasts of liner or wooden cushion block 3 between metal fixing 1 and exterior wall 8 outsides) make directly not contact between U type curtain wall metal fixing 1 and external wall 8 lateral surfaces and be off-state, resolve the bloated riveting screw 2 of hot cold bridge because of use again, so just can effectively avoid forming hot cold bridge between curtain wall metalwork and the external wall 8, block the exchange of architecture indoor and outdoor energy.Its U type curtain wall metal fixing 1 outside dimension is high (among the figure up and down between) * thick (about among figure between two outsides)=30mm～100mm * 75mm～150mm; Adiabatic duroplasts or wooden cushion block 3 outside dimensions are length * wide * thick=30mm～100mm * 30mm～100mm * 30mm～100mm.

2, on external wall 8 lateral surfaces, apply one deck insulating foam layer 4 then, play the effect that improves external wall 8 integral heat insulation heat-proof qualities, its insulating foam layer 4 wraps and makes the part of this fixture 1 to expose outside U type curtain wall metal fixing 1, so that install lightweight curtain wall panel 5, therefore, the THICKNESS CONTROL of insulating foam layer 4 is at 30mm～200mm.

3, at last lightweight curtain wall panel 5 usefulness self-tapping screws 6 are fixed on metal fixing 1 outside, between lightweight curtain wall panel 5 and insulating foam layer 4, maintain an air heat-insulation layer 7, this has certain effect to improving external wall entire system thermal and insulating performance, and the THICKNESS CONTROL of air heat-insulation layer 7 is at 30mm～150mm.

By above-mentioned job practices, between U type curtain wall metal fixing 1 and external wall 8, can not form energy channel, reach the effect of resolving hot cold bridge, and increase insulating foam layer 4 and air heat-insulation layer 7, improve external wall entire system thermal and insulating performance greatly, helped saving the energy.
