Problems solved by technology

Single-injection profiles can meet the requirements of general doors and windows, but because of the limited force of single-injection thermal insulation products, when encountering requirements for profiles with relatively high mechanical properties, single-injection thermal insulation products cannot meet the requirements
The process requirements of the injection product should have a slot for injection, and then cut the connecting rib (bridge) from the back of the slot for injection, so the development of injection products with double injection or more slots is restricted.

Embodiment 1

[0022] see Figure 2 to Figure 5 , a metal profile double injection glue heat insulation method is to use heat insulating glue (with the prior art) 3 to connect the first profile 1 and the second profile 2 into one, it is characterized in that it includes the following steps:

[0023] 1) First, the first profile 1 and the second profile 2 are connected through the connecting rib 3 to form an integral profile, and the two sides of the connecting rib 3 are respectively provided with the first heat-insulating glue connection cavity 4 and the second heat-insulating glue connection Cavity 5, first glue injection notch 41 and second glue injection notch 51 are respectively provided on the outside of first heat insulation glue connection cavity 4 and second heat insulation glue connection cavity 5;

[0024] 2) Inject heat insulating glue in the first glue injection slot 41, so that the heat insulating glue fills the first heat insulating glue connection cavity 4;

[0025] 3) Afte...

Embodiment 1

[0030] see figure 1 , the metal profile member made by the metal profile double injection glue heat insulation method is characterized in that it includes two parallel first profile 1 and second profile 2, the opposite side of the first profile 1 and the second profile 2, Each is provided with at least two corresponding slots that can form two connected heat-insulation glue connection cavities (two independent heat-insulation glue connection cavities can be formed before the middle connecting rib is cut off, such as figure 2 The first heat-insulating glue connects the cavity 4 and the second heat-insulating glue connects the cavity 5, and the two cavities are connected after cutting off), the first profile 1 and the second profile 2 pass through the connected heat-insulating cavity filled with the two cavities The glue is tightly connected and spaced apart, and a first glue injection notch 41 and a second glue injection notch 51 are respectively provided on both sides of the...

Abstract

The invention provides a metal section dual glue injection thermal insulation method and a component, and belongs to the technical field of building sections. The method mainly comprises the following steps that 1), an integral section is firstly prepared, a first section body and a second section body are arranged in parallel and are connected through a connecting rib, a first thermal insulation glue connecting cavity and a second thermal insulation glue connecting cavity are arranged on the two sides of the connecting rib respectively, and a first glue injection groove opening and a second glue injection groove opening are formed outside the cavities respectively; 2), thermal insulation glue is injected to the first glue injection groove opening; 3), after glue injection is completed, the connecting rib is cut out; 4), thermal insulation glue is injected to the second glue injection groove opening, and is connected with the thermal insulation glue of the first thermal insulation glue connecting cavity. The metal section dual glue injection thermal insulation method has the advantages that product connecting strength is high, the limit that single glue injection cannot reach high connecting strength is removed, the mechanical property of the section is greatly improved, the thermal insulation need of the section is met, the performance is stable, processing is convenient, and efficiency is high. The method and the component are especially suitable for section doors and windows, curtain walls and the like.

Description

technical field [0001] The invention relates to the technical field of building profiles, in particular to a double-injection glue heat insulation product, especially suitable for doors, windows and curtain walls. Background technique [0002] At present, most of the injection profiles on the market are single injection profiles, that is, the injection heat insulation products completed by one injection slot. Single-injection profiles can meet the requirements of general doors and windows, but because of the limited force of single-injection thermal insulation products, when encountering requirements for profiles with relatively high mechanical properties, single-injection thermal insulation products cannot meet the requirements. The process requirements of the injection product should have a slot for injection, and then cut the connecting rib (bridge) from the back of the slot for injection, so the development of injection products with double injection or more slots is res...
