Description

Technical Field

[0001] The present invention relates to the technical field of wall panels, and in particular to an external barrier for a building. Background Art

[0002] Aluminum wall panels are a high-performance material widely used in modern building exterior wall decoration and insulation systems. They have good mechanical strength, weather resistance and corrosion resistance, and can adapt to a variety of climatic conditions and external environmental influences. Their surface is usually treated with processes such as anodizing, fluorocarbon spraying or powder spraying to make the aluminum wall panels rich in color and high gloss, which can effectively enhance the overall beauty and modern feel of the building's appearance. At the same time, aluminum wall panels also have certain sound insulation and noise reduction functions, which can reduce the introduction of external noise, and can enhance the sealing of the wall through structural design, improve the building's insulation, waterproof and dustproof performance, and further improve the comfort and durability of use.

[0003] However, in the actual construction process, the existing installation method of aluminum wall panels still has certain limitations. At present, the installers usually need to manually fit the aluminum wall panels to the preset brackets, and perform on-site drilling operations in the corresponding areas of the brackets according to the positions of the fixing ears of the wall panels. The bolts are then passed through the fixing ears in turn and screwed into the mounting holes on the brackets to fix the wall panels. During this process, the installers need to operate the drilling, bolt hole alignment and bolt installation with one hand, and at the same time ensure the stability of the wall panels during installation to prevent displacement or misalignment. The overall installation process is cumbersome and is prone to problems such as bolt falling and aluminum wall panel displacement. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the above background art, the present invention provides an external barrier for a building.

[0005] Technical solution: An external barrier for a building, comprising an aluminum wall panel, wherein the aluminum wall panel is fixedly connected to a plurality of fixing ears, and the fixing ears are connected to a slider for limited sliding. The slider is provided with symmetrically distributed clamping parts, and the clamping parts are used to clamp the bolts required for the installation of the aluminum wall panel in advance. The fixing ears are provided with a limiting assembly for locking the slider.

[0006] In addition, it is particularly preferred that the clamping member has a wave-shaped structure, and the projection of the clamping member on the adjacent sliding block is an arc.

[0007] In addition, it is particularly preferred that the wave reversing points of the clamping members on the same slider are staggered for uniformly clamping the bolts.

[0008] In addition, it is particularly preferred that the clamping piece is elastic to facilitate the installation of the bolt.

[0009] In addition, it is particularly preferred that the limiting assembly includes a serrated bar, the serrated bar is fixedly connected to the fixing ear, the slider is fixedly connected to a clamping block, and the serrated bar limits the slider through the clamping block.

[0010] In addition, it is particularly preferred that the sliding block is provided with a groove, and the clamping block is located in the groove.

[0011] In addition, it is particularly preferred that an annular gasket is slidably connected inside the slider, and an annular inclined surface is provided on the inner side of the annular gasket close to the clamping member.

[0012] Furthermore, it is particularly preferred that the sliding block is located in the fixing ear, and the annular gasket is located in the sliding block.

[0013] In addition, it is particularly preferred that a connecting ring is fixedly connected to one side of the annular gasket close to the clamping member, the connecting ring is fixedly connected to all adjacent clamping members, and an elastic member is provided between the connecting ring and the slider.

[0014] Furthermore, it is particularly preferred that the elastic coefficient of the clamping member is greater than the elastic coefficient of the elastic member.

[0015] 1. This application changes the installation order of the bolts by pre-clamping the required bolts on the fixing ears of the aluminum wall panel before installation, thereby reducing the probability of the aluminum wall panel being offset when the worker tightens the bolts with one hand, and combines with a movable slider to quickly achieve bolt positioning and tightening after drilling is completed.

[0016] 2. The serrated bar and the clamping block cooperate to effectively prevent the slider from sliding unexpectedly during the subsequent adjustment of the aluminum wall panel, thereby reducing the risk of the bolts on the slider being detached from the clamping parts due to displacement, and improving the stability of the installation process and operational safety.

[0017] 3. By making the annular gasket fit the bracket, and the inner side of the annular gasket is squeezed by the outer wall of the bolt to produce elastic deformation, it fits tightly to the surface of the bolt, thereby achieving effective sealing of the bracket mounting hole and the bolt connection part, significantly reducing the risk of external moisture infiltration, and improving the overall connection reliability and durability of the aluminum wall panel.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The existing installation method of aluminum wall panels still has certain shortcomings. Currently, installers are usually required to manually attach and fix the wall panels to the preset brackets, and drill holes on site in the corresponding areas according to the positions of the wall panel's built-in fixing ears. The bolts are then passed through the fixing ears and screwed into the mounting holes of the brackets. During this process, the installer maintains the stability of the aluminum wall panel with one hand, while drilling, aligning the bolts, and tightening the bolts with one hand. The overall installation steps are cumbersome, and problems such as bolts falling off and aluminum wall panel displacement are very likely to occur.

[0027] Example 1

[0028] This embodiment discloses an external barrier for a building, which is used to speed up its installation speed.

[0029] like Figures 1-6As shown, it includes an aluminum wall panel 1, which is generally rectangular. Two long sides of the aluminum wall panel 1 are fixedly connected to two fixing ears 2. The two fixing ears 2 on the same side are symmetrically distributed in the middle of the aluminum wall panel 1. A slide groove is provided on the fixing ear 2. A slider 3 is connected to the slide groove of the fixing ear 2 in a limited sliding manner. A circular through hole is provided in the middle of the slider 3. The slider 3 is provided with two symmetrically distributed clamping members 4. In this embodiment, the two clamping members 4 are fixedly connected to the slider 3, but this is limited to this embodiment. The clamping members 4 are used to clamp the bolts required for the installation of the aluminum wall panel 1 in advance. The clamping members 4 have a wavy structure to increase the contact area with the bolts. The shaped structure is convenient for compression, and the clamping member 4 is projected into an arc shape on the adjacent slider 3, which is convenient for fitting the outside of the bolt. The radius of the circle where the arc of the clamping member 4 is projected on the adjacent slider 3 is smaller than the radius of the through hole in the middle of the slider 3, and the diameter of the circle surrounded by the two clamping members 4 is smaller than the diameter of the threaded part of the bolt, so that after the bolt enters between the two clamping members 4, the two clamping members 4 form a clamping force on the bolt. The wave reversing points of the clamping members 4 on the same slider 3 are staggered and distributed, which is used to uniformly clamp the bolt. The clamping member 4 is elastic and can be radially compressed into the slider 3, which is convenient for the installation of the bolt. A limiting component for locking the slider 3 is provided on the fixing ear 2.

[0030] The above setting can be achieved by pre-clamping the bolts in the two clamping parts 4 on the slider 3, and using the slide groove on the fixing ear 2 for positioning and drilling. After the drilling is completed, push the slider 3 to the installation hole, and after the two are aligned with each other, tighten the bolt so that its head fits with the slider 3, and the clamping parts 4 shrink under the action of pressure. By changing the installation order of the bolts, the probability of the aluminum wall panel being offset when the staff tightens the bolts with one hand is reduced.

[0031] like Figure 2-Figure 5 As shown, the limiting assembly includes two serrated bars 5, which are fixedly connected to the fixed ear 2, and the two serrated bars 5 are symmetrically distributed on both sides of the slide groove of the fixed ear 2. The slider 3 is fixedly connected with two symmetrically distributed blocks 6. The connection between the block 6 and the slider 3 is elastic and can undergo elastic deformation when subjected to external force, driving the block 6 to deflect. The serrated bar 5 limits the slider 3 through the block 6. The slider 3 is provided with a groove 7. The block 6 is located in the groove 7. The block 6 deflects in the groove 7 to reduce the space occupied by the block 6.

[0032] The above setting can be achieved. When the slider 3 moves along the slide groove on the fixed ear 2, the block 6 is driven to move synchronously. The block 6 contacts and is compressed with the serrated bar 5. Under the action of the extrusion force, the block 6 is deflected and separated from the tooth groove of the adjacent serrated bar 5. After the slider 3 drives the block 6 to move and cross the adjacent serrated block, the block 6 rebounds and is embedded in the tooth groove of the serrated bar 5. This cycle is repeated until the slider 3 reaches the mounting hole position. The block 6 moves along the serrated block of the serrated bar 5 under the action of elastic force and is stuck in the tooth groove of the serrated bar 5, forming a mechanical limit to prevent the slider 3 from sliding accidentally and reduce the risk of the bolt and the clamp 4 being detached, thereby improving the installation stability and operational safety.

[0033] When it is necessary to install the aluminum wall panel 1 on the exterior wall of the building, the staff will first clamp the bolts used for fixing in the two clamping parts 4 on each slider 3 and ensure that they are firm and reliable. Then, the operator will adjust the aluminum wall panel 1 to a position that fits the bracket and perform preliminary positioning to ensure installation accuracy. Then, the punching device will be started to accurately drill holes in the bracket through the slide groove on the fixing ear 2.

[0034] After the drilling is completed, the staff pushes the slider 3 along the slide groove to the mounting hole, and then uses a wrench or power tool to apply downward pressure on the bolt and rotate it so that the bolt can be smoothly screwed into the mounting hole inside the bracket. During this process, the clamping part 4 produces radial contraction under the pressure of the bolt and is gradually retracted into the interior of the slider 3 until the bolt head is tightly fitted with the surface of the slider 3, completing the fastening connection at this point. The remaining connection points are operated in sequence according to this process until the entire aluminum wall panel 1 is firmly installed on the bracket. This application changes the installation order of the bolts by pre-clamping the required bolts on the fixing ears 2 before installation, thereby reducing the probability of the aluminum wall panel being offset when the staff tightens the bolts with one hand, and combined with the movable slider 3, the bolt positioning and tightening can be quickly achieved after the drilling is completed.

[0035] When the slider 3 moves along the slide groove on the fixed ear 2, it will drive the two blocks 6 on it to slide synchronously. During this process, the block 6 contacts the serrated block on the adjacent serrated bar 5 and produces an extrusion effect. After the block 6 is subjected to force, it elastically deforms and deflects. Under the continuous movement of the slider 3 driving the block 6, the block 6 passes over the serrated block, rebounds under the action of elastic force and embeds into the tooth groove of the adjacent serrated bar 5. This cycle continues. When the slider 3 drives the bolt to slide to the installation hole position, the operator stops pushing the slider 3. At this time, the block 6 is no longer subjected to the extrusion force of the serrated bar 5, and is stably stuck in the tooth groove of the serrated bar 5 under the action of its own elastic force, forming a mechanical limit structure. Through the cooperation between the serrated bar 5 and the block 6, the slider 3 is effectively prevented from unexpectedly sliding during the subsequent adjustment of the aluminum wall panel 1, thereby reducing the risk of the bolt on the slider 3 being detached from the clamping member 4 due to displacement, thereby improving the stability and operational safety of the installation process.

[0036] Example 2

[0037] This embodiment discloses an external barrier for a building, which is a further improvement on the basis of the first embodiment.

[0038] like Figure 4 and Figure 6 As shown, an annular gasket 8 is slidably connected in the through hole in the middle of the slider 3. The annular gasket 8 is made of elastic material, and the inner radius of the annular gasket 8 is smaller than the radius of the threaded portion of the bolt. The inner side of the upper side of the annular gasket 8 is provided with an annular inclined surface to facilitate the entry of the bolt. The slider 3 is located in the fixed ear 2, and the annular gasket 8 is located in the slider 3, that is, the lower side of the slider 3 is higher than the lower side of the fixed ear 2, and the lower side of the annular gasket 8 is not lower than the lower side of the slider 3, so that when the slider 3 slides along the slide groove of the fixed ear 2, the annular gasket 8 does not It contacts the bracket, reduces the movement resistance of the slider 3, and reduces the wear of the annular gasket 8. The upper side of the annular gasket 8 is fixedly connected with a connecting ring 9. In this embodiment, the connecting ring 9 is fixedly connected to the two clamping members 4, and the clamping members 4 are not connected to the slider 3. An elastic member 10 is provided between the connecting ring 9 and the slider 3. The elastic member 10 is a tension spring, which is used to control the annular gasket 8 to be in the slider 3. The elastic coefficient of the clamping member 4 is greater than the elastic coefficient of the elastic member 10, which is used to make the elastic member 10 stretch before the clamping member 4.

[0039] During the installation process, when the operator uses a wrench or an electric tool to apply downward pressure on the bolt and rotate it, so that it is gradually screwed into the mounting hole of the bracket, the bolt head will continue to apply extrusion force to the two clamping parts 4. At this time, the two clamping parts 4 push the annular gasket 8 to slide along the slider 3 through the connecting ring 9 until the annular gasket 8 is tightly fitted with the surface of the bracket. In this process, the elastic part 10 is stretched. As the bolt continues to penetrate into the mounting hole, the bolt head further squeezes the clamping part 4. Since the annular gasket 8 is limited by the bracket and cannot continue to move, the two clamping parts 4 will radially shrink under the action of the extrusion force and then be retracted into the interior of the slider 3 until the bolt head is completely fitted with the surface of the slider 3, completing the tightening operation at this point. In this process, the inner side of the annular gasket 8 is squeezed by the outer wall of the bolt and produces elastic deformation, which fits tightly to the bolt surface, thereby achieving effective sealing of the bracket mounting hole and the bolt connection part, significantly reducing the risk of external moisture infiltration, preventing bolt rust, improving the overall connection reliability and durability of the aluminum wall panel 1, and enhancing the stability and sealing performance of the installation structure.

[0040] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
