Description

Technical Field

[0001] The present utility model relates to the technical field of aluminum profiles, and particularly relates to a heat-insulating broken-bridge aluminum material. Background Art

[0002] With the improvement of the public's environmental protection awareness, energy-saving buildings have become a trend. Among them, heat-insulating broken-bridge aluminum materials, as a kind of energy-saving building materials, have been widely used.

[0003] As Figure 1 shown, in order to improve the heat-insulating performance, it is necessary to add foamed cotton between the heat-insulating strip and the profile, but the process of filling foamed cotton will increase the labor cost and the production cycle. At the same time, the existing heat-insulating broken-bridge aluminum materials generally use heat-insulating strips made of PA66 + 25% glass fiber to partition the broken-bridge doors and windows. Among them, the thermal conductivity of PA66 is about between 0.2 and 0.3 W / (m·K); however, after the commonly used heat-insulating strip materials such as PA66 reach a certain width, their mechanical properties and stability will be affected; with the increase of the width, the flexural strength, tensile strength, etc. of the material may decrease, thus affecting the overall performance and durability of the heat-insulating strip; specifically, the longest width of the heat-insulating strip on the market at present is 64 mm. When the length required by the customer is longer, it can only be filled by increasing the aluminum profile, and such a method requires a large amount of cost.

[0004] In addition, with the development of the sealing technology of doors and windows, modern broken-bridge doors and windows usually adopt a multi-channel sealing design, including rubber sealing strips, rubber strips, etc., to prevent the penetration of air and moisture; however, during the installation process, high technical requirements are needed, and the professional level of the installers is also required to be high, which also increases the installation difficulty and cost. If problems such as aging and falling off of the sealing rubber strips occur, it is more difficult to repair. Content of the Utility Model

[0005] The technical problem to be solved by the present utility model is to provide a heat-insulating broken-bridge aluminum material with a simple structure, firm connection, good sealing performance and good heat-insulating performance.

[0006] To solve the above technical problem, the present utility model provides a heat-insulating broken-bridge aluminum material, which includes a first aluminum alloy member, a second aluminum alloy member, a connecting member and a rigid foamed polyurethane heat-insulating block.

[0010] As an improvement of the above solution, the inner butt joint structure includes a second connecting strip located on the opposite side of the first connecting strip. The end of the second connecting strip is provided with a second clamping part. The first connecting strip and the second connecting strip are used to bear the main tensile force of the rigid foamed polyurethane heat insulation block and the aluminum alloy part.

[0011] As an improvement of the above solution, the inner butt joint structure includes a torsion-resistant connecting piece arranged outside the second connecting strip. The torsion-resistant connecting piece includes a torsion-resistant substrate perpendicular to the plate-shaped connecting body and extension plates horizontally extending from the end of the torsion-resistant substrate to both sides. A third clamping part is provided at one end of the extension plate close to the second connecting strip, and the third clamping part is used to bear the lateral force from the rigid foamed polyester polyurethane material.

[0012] As an improvement of the above solution, an edge tensile strip is provided at one end of the extension plate away from the second connecting strip. The edge tensile strip is connected with an adhesive plane. The edge tensile strip is used to protect the edge of the easily damaged rigid foamed polyester polyurethane heat insulation block, so that the two have a large adhesive surface and ensure the adhesive effect.

[0013] As an improvement of the above solution, protective skirt edges are provided on both sides of the plate-shaped connecting body. The outer surface of the protective skirt edge is flush with the outer surface of the rigid foamed polyester polyurethane heat insulation block. The protective skirt edge can facilitate the protection of the surface of the easily damaged rigid foamed polyester polyurethane heat insulation block during transportation and installation.

[0014] As an improvement of the above solution, the rigid foamed polyurethane heat insulation block and the connecting piece are integrally formed, so as to reduce the gap between the rigid foamed polyurethane heat insulation block and the connecting piece and improve the heat insulation effect of the overall structure.

[0024] To make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the upper, lower, left, right, front, rear, inner, outer and other orientation terms that appear or will appear in this invention are only based on the drawings of the present invention, and they do not specifically limit the present invention.

[0025] Such as Figure 2As shown in the figure, the heat-insulating and bridge-cut aluminum profile of the present utility model includes a first aluminum alloy member 3, a second aluminum alloy member 4, a connecting member 2, and a rigid foamed polyurethane heat-insulating block 1; the connecting member 2 is provided at both ends of the rigid foamed polyurethane heat-insulating block 1.

[0026] As Figure 3 , Figure 4 shown, the connecting member 2 includes an inner butt-joint structure 21 for connecting with the rigid foamed polyurethane heat-insulating block 1, and an outer butt-joint structure 22 for connecting with the corresponding first aluminum alloy member 3 or second aluminum alloy member 4; the connecting member includes a plate-shaped connecting body 23, and the outer butt-joint structure 22 includes a first connecting strip 221 provided on one surface of the plate-shaped connecting body 23, and a first clamping portion 222 is provided at the end of the first connecting strip 221; connection grooves are provided on the first aluminum alloy member 3 and the second aluminum alloy member 4, and the first clamping portion 222 can be clamped into the connection grooves to connect and fix the connecting member 2 with the corresponding first aluminum alloy member 3 or second aluminum alloy member 4.

[0027] It should be noted that since the first aluminum alloy member 3, the second aluminum alloy member 4, and the rigid foamed polyurethane heat-insulating block 1 form an integral body through the inner butt-joint structure 21 and the outer butt-joint structure 22 of the connecting member 2, it has a stable structure and has the effect of extending the service life.

[0028] Furthermore, in this embodiment, two groups of first connecting strips 221 are adopted. The two groups of first connecting strips 221 need to be installed in parallel on the surface of the plate-shaped connecting body 23. When installing, the first connecting strips 221 need to enclose a heat-insulating cavity between the first aluminum alloy member 3 and the second aluminum alloy member 4, and the heat-insulating cavity can play the role of improving the overall heat-insulating performance of the heat-insulating and bridge-cut aluminum profile.

[0029] Correspondingly, in this embodiment, the inner butt-joint structure 21 includes a second connecting strip 223 located on the opposite side of the first connecting strip 221, and a second clamping portion 224 is provided at the end of the second connecting strip 223; the second clamping portion 224 needs to be connected to the rigid foamed polyurethane heat-insulating block 1. Since the second clamping portion 224 is a vertical protrusion and is located on both sides of the connecting portion 2, it can bear the main tensile force of the rigid foamed polyurethane heat-insulating block 1 and the aluminum alloy member.

[0030] Specifically, in this embodiment, the second connecting strip 223 is a part of the inner docking structure. It is fixed to the outer edge of the plate-shaped connecting body 23. The second connecting strip 223 allows it to withstand torque in the horizontal direction. The anti-torsion substrate 227 is located outside the second connecting strip 223 and is used to increase the anti-torsion ability of the structure. The anti-torsion substrate 227 is perpendicular to the plate-shaped connecting body 23 and is directly installed on the outer edge of the plate-shaped connecting body 23 to bear the torsion force from the second connecting strip 223. The extension plates 228 extend horizontally from the ends of the anti-torsion substrate 227 to both sides, forming two symmetrical extension plates 228. The extension plates 228 increase the anti-torsion area of the connecting member 2 and enhance the overall anti-torsion ability of the structure.

[0031] In addition, in this embodiment, the third clamping portion 225 is provided at one end of the extension plate close to the second connecting strip 223. As a structure for accurately docking and fixing with the second connecting strip 223, it can effectively resist torsional loads and bear a certain amount of lateral force and torsion force.

[0032] Preferably, in this embodiment, an edge tensile strip 226 is provided at one end of the extension plate 228 away from the second connecting strip 223, which can play a role in protecting the edge of the easily damaged rigid foamed polyurethane heat block 1. The edge tensile strip 226 is connected with an adhesive plane, and a relatively large adhesive surface is set to ensure the adhesive effect.

[0033] Furthermore, in this embodiment, protective skirt edges 229 are provided on both sides of the connecting body 23. The outer surface of the protective skirt edges 229 is flush with the outer surface of the rigid foamed polyurethane heat insulation block 1, and it has the function of protecting the surface of the rigid foamed polyurethane heat insulation block during transportation and installation.

[0034] Preferably, as Figure 2 shown, the rigid foamed polyurethane heat insulation block 1 and the connecting member 2 are integrally formed, which has better overall structural strength, reduces the use of materials, lowers the cost, and the integral formation can ensure that the heat insulation material is continuously distributed throughout the product without interruption or gaps, thus avoiding the formation of thermal bridges and preventing the reduction of the heat insulation effect. The connecting member 2 is made of PVC plastic, which has good flexibility and chemical resistance and can still maintain its original shape and size after long-term use.

[0035] It should be noted that the connecting member in the above embodiment is made of PVC plastic, but it is not limited to this.

[0036] Furthermore, in this embodiment, both the first aluminum alloy member 3 and the second aluminum alloy member 4 have a frame portion. The frame provides the necessary structural support for the product and can make the connecting member and the rigid foamed polyurethane material 1 be more stably fixed between the first aluminum alloy member 3 and the second aluminum alloy member.

[0037] As can be seen from the above, by introducing the rigid foamed polyurethane material 1, the utility model reduces the usage amount of the heat-insulating broken-bridge aluminum profile, and at the same time, due to its one-piece structure design, the stability is enhanced and the service life is extended.

[0038] The above is the preferred embodiment of the utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements can be made without departing from the principle of the invention, and these improvements and refinements are also regarded as the protection scope of the utility model.
