Description

Technical Field

[0001] The utility model relates to the field of aluminum profiles, in particular to a broken bridge aluminum structure. Background Art

[0002] In the fields of building decoration and interior decoration, people widely use aluminum profiles to make windows, doors and various partitions. Aluminum profiles are also widely praised by users for their light weight, beauty and fire resistance.

[0003] As Figure 1 shown, a cross-section of a broken bridge aluminum casement window is shown. The heat insulation strip 2 is installed in the dovetail grooves 3 of the left and right frames 1. Each heat insulation strip needs to be clamped and fixed by two dovetail grooves on the left and right. At the same time, two sets of heat insulation strips are required to form a sealed space for heat insulation. Therefore, two heat insulation strips need four dovetail grooves. Too many dovetail grooves increase the cost, increase the weight of the window, and at the same time, threading two sets of heat insulation strips also increases the installation difficulty and the installation efficiency is not high.

[0004] Chinese Patent with the authorization announcement number CN202718541U discloses a reinforced heat insulation and waterproof inner fan aluminum profile. In the scheme, a pair of corresponding dovetail-shaped clamping grooves are respectively opened on the inner side surfaces of the inner and outer profiles, and heat insulation strips are inserted into the upper and lower corresponding dovetail-shaped clamping grooves. The two ends of the heat insulation strip are respectively matched with the dovetail-shaped clamping grooves, and a cavity is arranged in the middle.

[0005] The scheme of this patent adopts an integral hollow heat insulation strip, which realizes the sealed heat insulation effect through one heat insulation strip. At the same time, because only one heat insulation strip is adopted, only two dovetail grooves are correspondingly arranged, which saves cost and improves the threading efficiency.

[0006] However, this scheme still has certain deficiencies. Since the heat insulation strip is a hollow structure and lacks internal support, the overall strength of the heat insulation strip is limited. At the same time, after being installed in the frame and used for a long time, the heat insulation strip is prone to deformation and shrinkage, resulting in the heat insulation strip not being able to fit tightly with the dovetail groove, and the sealing ability decreases.

[0007] Therefore, there is an urgent need for a heat insulation strip that can adjust the strength and has strong resilience and reset ability to improve the sealing and heat insulation effects of the broken bridge aluminum. Summary of the Utility Model

[0008] The purpose of the utility model is to provide a broken bridge aluminum structure to solve the problems existing in the background art.

[0009] The purpose of the utility model is realized by the following technical solutions:

[0010] A broken bridge aluminum structure includes a frame body and a heat insulation strip. The heat insulation strip is of a hollow structure, and the frame body is provided with a dovetail groove for clamping the heat insulation strip. It is characterized in that: reinforcing ribs are arranged in the frame body, the reinforcing ribs evenly divide the cavity of the heat insulation strip into two parts, and a rebound limiting component is arranged in the cavity of the heat insulation strip, and the two rebound limiting components are respectively located on both sides of the reinforcing ribs.

[0011] Further, the rebound limiting component includes a corrugated plate, the wave propagation direction of the corrugated plate is perpendicular to the reinforcing rib, one end of the corrugated plate is fixed to the middle of the inner wall of the heat insulation strip, and the other end of the corrugated plate is fixed to the middle of the reinforcing rib.

[0012] Further, the rebound limiting component includes a first U-shaped plate and a second U-shaped plate. The open end of the first U-shaped plate is fixed to the inner wall of the heat insulation strip, and the closed end of the first U-shaped plate does not contact the reinforcing rib; the open end of the second U-shaped plate is fixed to the reinforcing rib, and the closed end of the second U-shaped plate does not contact the inner wall of the heat insulation strip.

[0013] Further, the first U-shaped plate and the second U-shaped plate have the same size specifications, and the first U-shaped plate and the second U-shaped plate are clamped in a cross shape.

[0014] Further, the first U-shaped plate and the second U-shaped plate have the same size specifications, and the open end of the first U-shaped plate is fixed to the open end of the second U-shaped plate.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1) Heat insulation and sealing can be completed through one heat insulation strip, reducing the number of dovetail grooves, saving the cost of aluminum profiles, and at the same time, only installing one heat insulation strip is also convenient for installation and can improve the installation efficiency.

[0017] 2) The reinforcing ribs evenly divide the cavity of the heat insulation strip into two parts, improving the supporting effect on the cavity of the heat insulation strip, and at the same time, the two separated cavities can further improve the sealing and heat insulation effect.

[0018] 3) The corrugated plate is used to resist pressure and release energy. After the external pressure disappears, the heat insulation strip can be reset through the corrugated plate to prevent the heat insulation strip from being extruded and deformed.

[0019] 4) The limiting of the first U-shaped plate and the second U-shaped plate can ensure that the heat insulation strip has a certain shrinkage, which is convenient for inserting into the dovetail groove and fixing with the frame body. At the same time, the first U-shaped plate and the second U-shaped plate can also support the heat insulation strip after the maximum limit, improving the strength of the heat insulation strip.

[0025] Next, in combination with the embodiments, the technical solutions of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figure 1 shown, what is shown is a cross-section of a broken bridge aluminum casement window. The heat insulation strip 2 is installed in the dovetail grooves 3 of the left and right frame bodies 1. Each heat insulation strip 2 needs to be clamped and fixed by two dovetail grooves 3 on the left and right. At the same time, two sets of heat insulation strips 2 are required to form a sealed space for heat insulation. Therefore, two heat insulation strips 2 need four dovetail grooves 3. Too many dovetail grooves 3 increase the cost of the aluminum profile, increase the weight of the window, and at the same time, threading two sets of heat insulation strips 2 also increases the installation difficulty and the installation efficiency is not high.

[0027] Embodiment 1

[0028] As Figure 2 shown, the heat insulation strip 2 is a square hollow structure and is clamped and fixed to the frame body 1 through the dovetail groove 3. Heat insulation and sealing can be completed through one heat insulation strip 2, reducing the number of dovetail grooves 3, saving the cost of the aluminum profile, and at the same time, only installing one heat insulation strip 2 is also convenient for installation and can improve the installation efficiency.

[0029] Continuing as Figure 2 shown, a reinforcing rib 21 is arranged in the middle of the cavity of the heat insulation strip 2 of this solution. The reinforcing rib 21 is fixed to the heat insulation strip 2 as a whole. The cavity of the heat insulation strip 2 is evenly divided into two parts by the reinforcing rib 21, improving the supporting effect on the cavity of the heat insulation strip 2. At the same time, the two separated cavities can further improve the sealing and heat insulation effect.

[0030] Further, a corrugated plate 22 is provided on each side of the reinforcing rib 21. The wave propagation direction of the corrugated plate 22 is perpendicular to the reinforcing rib 21. When the heat insulation strip 2 is extruded in a direction perpendicular to the reinforcing rib 21, the pressure will be transmitted to the corrugated plate 22, and the corrugated plate 22 is used to resist the pressure and release energy. After the external pressure disappears, the heat insulation strip 2 can be reset through the corrugated plate 22, avoiding the deformation of the heat insulation strip 2 due to extrusion. The corrugated plate 22 can ensure that the heat insulation strip 2 is in contact with the frame body 1 to ensure the sealing effect.

[0031] Embodiment 2

[0032] Refer to Figure 3 , a reinforcing rib 21 is provided in the middle of the cavity of the heat insulation strip 2 of this solution. The reinforcing rib 21 is fixed integrally with the heat insulation strip 2. The cavity of the heat insulation strip 2 is evenly divided into two parts by the reinforcing rib 21, improving the support effect on the cavity of the heat insulation strip 2. At the same time, the two separated cavities can further improve the sealing and heat insulation effect.

[0033] Further, the resilience limiting component adopts a first U-shaped plate 23 and a second U-shaped plate 24. The size specifications of the first U-shaped plate 23 and the second U-shaped plate 24 are the same, and the first U-shaped plate 23 and the second U-shaped plate 24 are clamped in a cross shape. At the same time, the open end of the first U-shaped plate 23 is fixed to the inner wall of the heat insulation strip 2, and the closed end of the first U-shaped plate 23 does not contact the reinforcing rib 21; the open end of the second U-shaped plate 24 is fixed to the reinforcing rib 21, and the closed end of the second U-shaped plate 24 does not contact the inner wall of the heat insulation strip 2.

[0034] When the heat insulation strip 2 is extruded in a direction perpendicular to the reinforcing rib 21, the closed end of the first U-shaped plate 23 will abut against the reinforcing rib 21, and at the same time, the closed end of the second U-shaped plate 24 will abut against the heat insulation strip 2. At this time, the maximum compressible distance of the heat insulation strip 2 is limited by the first U-shaped plate 23 and the second U-shaped plate 24. When the heat insulation strip 2 reaches the maximum compression distance of the first U-shaped plate 23 and the second U-shaped plate 24, at this time, the first U-shaped plate 23 and the second U-shaped plate 24 play a role of supporting and limiting the heat insulation strip 2, avoiding the deformation of the cavity caused by further compression of the heat insulation strip 2.

[0035] The limiting by the first U-shaped plate 23 and the second U-shaped plate 24 can ensure that the heat insulation strip 2 has a certain contraction, which is convenient for inserting into the dovetail groove 3 and fixing with the frame body 1. At the same time, the first U-shaped plate 23 and the second U-shaped plate 24 can play a supporting role for the heat insulation strip 2 after the maximum limit, improving the strength of the heat insulation strip 2.

[0036] Embodiment 3

[0037] On the basis of Embodiment 2, refer to Figure 4, the open end of the first U-shaped plate 23 is fixed to the open end of the second U-shaped plate 24, and the first U-shaped plate 23 and the second U-shaped plate 24 are connected as a whole to form an S-shaped structure.

[0038] Since the closed end of the first U-shaped plate 23 does not contact the reinforcing rib 21, and the closed end of the second U-shaped plate 24 does not contact the inner wall of the heat insulation strip 2, the heat insulation strip 2 can be limited by the first U-shaped plate 23 and the second U-shaped plate 24. At the same time, the first U-shaped plate 23 and the second U-shaped plate 24 are connected as a whole, which can further improve the supporting effect on the heat insulation strip 2.

[0039] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in the relevant field. And any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
