Problems solved by technology

However, this method usually uses more materials. Although it can ensure the strength of the building when used in high-rise buildings, it will bring problems such as seriousness and waste of materials; during the installation and lifting of building panels, due to their large volume, Heavy weight will greatly increase the labor intensity of construction personnel, and there are certain safety hazards

Embodiment 1

[0031] Such as figure 1 Shown: a flanging core material, including an upper panel 1, a lower panel 2, several core tubes 3 in the middle, and a brazing layer 4 between the core tube 3, the upper panel 1, and the lower panel 2, and the upper and lower sides of the core tube 3 Both ends are flanged, so that the outer diameter after flanging is greater than the diameter of the core tube 3; The sides 31 are closely arranged, and after the arrangement, the brazing layer 4 is formed on the flanging by brazing material.

[0032] The brazing layer 4 is punched and flanged, so that the core tube 3 is positioned on the flanging of the brazing layer 4 .

[0033] In this embodiment, the brazing material is copper brazing material, and the brazing layer 4 is provided with a hollow 5 at the non-core tube, and the hollow is formed into a triangle. The edge of the brazing layer 4 of the hollow 5 is strengthened by flanging, and the flanging is perpendicular to the plane of the brazing layer...

Embodiment 2

[0039] Such as figure 2 with image 3Shown: The difference from Example 1 is that a brazed sandwich composite panel includes an upper panel 1, a lower panel 2, several core tubes 3 in the middle, and a connection between the core tube 3 and the upper panel 1 and the lower panel 2. Brazing layer 4'; several core tubes 3 are arranged at intervals, and the distance between adjacent core tubes is 20mm. By arranging several core tubes at intervals, the number of core tubes can be saved, the cost can be reduced, and the brazing time can be shortened . The upper and lower ends of the core tube 3 are all flanged, and the flanges 31 of the core tube 3 and the upper panel 1, the lower panel 2 and between the flanges 31 of the core tube 3 and the flanges of other adjacent core tubes are brazed. Welded.

[0040] Specifically, the brazing layer 4' is punched and flanged, that is, the brazing material wraps the flanging 31 of the core tube 3 and extends into the core tube 3, so that the...

Embodiment 3

[0046] Such as Figure 4 Shown: the difference from Example 2 is that the brazing layer 4 is provided with a hollow 5 "at the non-core tube. Wherein, the specific structure of the hollow 5 " is: between the flanges 31 of adjacent core tubes 3 through brazing The welded connecting ribs 51 are connected into one body, that is, a radial structure is formed with the core tube 3 as the center, and a brazed rib 52 is arranged between the hollow structures between every three adjacent core tubes 3 to strengthen , that is, one of the connecting ribs 51 among the three adjacent core tubes 3 is provided with a reinforcing rib 52 between the flanges 31 of the core tube 3 opposite to it.

[0047] Other structures are with embodiment 1.

Abstract

The invention discloses a flanged core material. The flanged core material comprises an upper panel, a lower panel, a plurality of core tubes in the middle, and brazing layers between the core tubes and the upper panel and between the core tubes and the lower panel. Both upper and lower ends of the core tube are flanged. The flanges of the core tubes are brazed with the upper and lower panels. Theflanged core material has the minimum material use amount on the premise of the same strength, has the maximum strength on the premise of the same weight, improves joint interface strength between the core tubes and the brazing material thereby improving the tensile strength and impact thermal stress of the whole brazing layer, and has good thermal insulation and sound insulation effects.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a flanging core material. Background technique [0002] In the construction industry, building materials are of particular importance, as building materials are combined to form beams, slabs or columns in buildings. [0003] With the advancement of industrialization and modernization, due to the better supporting strength of cement boards, most modern societies use cement boards as base materials such as beams and columns to make houses stronger. However, the use of cement board as a building base material has disadvantages such as heavy weight, long construction period, susceptibility to disturbance during construction, and non-environmental protection. In order to solve these problems, the construction industry began to use metal materials as building materials. [0004] In the prior art, a solid steel plate is usually used as a building base material, and the high-strength ...
