Description

Technical Field

[0001] The 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 surfaces are usually treated with processes such as anodizing, fluorocarbon spraying or powder spraying to make the aluminum wall panels rich in color and high in gloss, which can effectively enhance the overall beauty and modern sense 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, installers are usually required 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 the installation process to prevent offset or misalignment. The overall installation process is cumbersome and is prone to problems such as bolt falling and aluminum wall panel offset. Summary of the invention

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

[0005] Technical solution: An external barrier for a building, comprising an aluminum wall panel, the aluminum wall panel being fixedly connected with a plurality of fixing ears, the fixing ears being limitedly slidably connected with a slider, the slider being provided with symmetrically distributed clamping members, the clamping members being used to clamp the bolts required for the installation of the aluminum wall panel in advance, and the fixing ears being 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 shape.

[0007] In addition, it is particularly preferred that the wave reversal points of the clamping members on the same sliding block 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 component includes a saw tooth rack, the saw tooth rack is fixedly connected to the fixed ear, the slider is fixedly connected with a clamping block, and the saw tooth rack limits the slider through the clamping block.

[0010] In addition, it is particularly preferred that the slider 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 in the slider, and an annular inclined surface is arranged on the inner side of the annular gasket close to the clamping member.

[0012] In addition, it is particularly preferred that the slider is located in the fixed ear, and the annular gasket is located in the slider.

[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 arranged between the connecting ring and the slider.

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

[0015] 1. In this application, by pre-clamping the required bolts on the fixed ears of the aluminum wall panel before installation, changing the installation sequence of the bolts, reducing the probability of the aluminum wall panel shifting when the staff tightens the bolts with one hand, and combining with the movable slider, the positioning and tightening of the bolts can be quickly achieved after drilling.

[0016] 2. Through the cooperation of the saw tooth rack and the clamping block, it effectively prevents the slider from sliding unexpectedly during the subsequent adjustment of the aluminum wall panel, thereby reducing the risk of the bolts on the slider detaching from the clamping member due to displacement, and improving the stability and operation safety of the installation process.

[0017] 3. By making the annular gasket fit the bracket, and the inner side of the annular gasket is elastically deformed by the extrusion of the outer wall of the bolt and tightly fits on the surface of the bolt, thereby effectively sealing the connection part between the installation hole of the bracket and the bolt, significantly reducing the risk of external moisture infiltration, and improving the overall connection reliability and durability of the aluminum wall panel.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0021] The existing installation method of aluminum wall panels still has certain shortcomings. Currently, installers are usually required to manually affix and fix the wall panels to the preset brackets, and drill holes on site in the corresponding areas 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 of the brackets. During this process, the installers maintain the stability of the aluminum wall panels with one hand, and drill holes, align the bolts with the holes, and tighten the bolts with one hand at the same time. The overall installation steps are cumbersome, and problems such as bolts falling off and aluminum wall panel displacement are very likely to occur.

[0022] Example 1 This embodiment discloses an external barrier for a building, which is used to speed up its installation rate.

[0023] like Figures 1-6As shown in the figure, it includes an aluminum wall panel 1. The aluminum wall panel 1 is usually rectangular. Two fixing ears 2 are fixedly connected to both long sides of the aluminum wall panel 1. The two fixing ears 2 on the same side are symmetrically distributed with respect to the middle of the aluminum wall panel 1. A chute is provided on the fixing ear 2, and a slider 3 is slidably connected in the chute of the fixing ear 2 in a limited manner. A circular through hole is provided in the middle of the slider 3, and two clamping members 4 are symmetrically distributed on the slider 3. In this embodiment, the two clamping members 4 are fixedly connected to the slider 3, but only in this embodiment. The clamping member 4 is used to pre-clamp the bolts required for the installation of the aluminum wall panel 1. The clamping member 4 has a wavy structure, which increases the contact area with the bolt. The wavy structure is easy to compress, and the projection of the clamping member 4 on the adjacent slider 3 is arc-shaped, which is convenient for fitting the outside of the bolt. The radius of the circle where the arc of the projection of the clamping member 4 on the adjacent slider 3 is located is smaller than the radius of the through hole in the middle of the slider 3, and the diameter of the circle formed by the two clamping members 4 is smaller than the diameter of the threaded part of the bolt. After the bolt enters between the two clamping members 4, the two clamping members 4 form a clamping force on the bolt. The wave reversal points of the clamping members 4 on the same slider 3 are staggeredly distributed for uniformly clamping the bolt. The clamping member 4 has elasticity and can be radially compressed and retracted into the slider 3 for the convenience of bolt installation. A limiting component for locking the slider 3 is provided on the fixing ear 2.

[0024] The above settings can achieve pre-clamping the bolt in the two clamping members 4 on the slider 3 and using the chute on the fixing ear 2 for positioning and drilling. After the drilling is completed, the slider 3 is pushed to the installation hole, and after they are aligned with each other, the bolt is tightened so that its head fits the slider 3. The clamping member 4 contracts under pressure. By changing the installation order of the bolt, the probability of the aluminum wall panel shifting when the staff tightens the bolt with one hand is reduced.

[0025] As Figures 2-5 shown, the limiting component includes two sawtooth racks 5. The two sawtooth racks 5 are fixedly connected to the fixing ear 2, and the two sawtooth racks 5 are symmetrically distributed on both sides of the chute of the fixing ear 2. The slider 3 is fixedly connected with two symmetrically distributed blocks 6. The connection between the block 6 and the slider 3 has elasticity and can undergo elastic deformation when subjected to an external force, driving the block 6 to deflect. The sawtooth rack 5 limits the slider 3 through the block 6. The slider 3 is provided with a groove 7, and 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.

[0026] The above settings can achieve that when the slider 3 moves along the chute on the fixed ear 2, it drives the clamping block 6 to move synchronously. The clamping block 6 contacts and is pressed by the saw tooth rack 5. Under the extrusion force, the clamping block 6 deflects and separates from the tooth groove of the adjacent saw tooth rack 5. And after the slider 3 drives the clamping block 6 to move and cross the adjacent saw tooth block, the clamping block 6 rebounds and is embedded into the tooth groove of the saw tooth rack 5. This cycle continues until the slider 3 reaches the installation hole position. Then, under the action of the elastic force, the clamping block 6 moves along the saw tooth block of the saw tooth rack 5 and is clamped into the tooth groove of the saw tooth rack 5, forming a mechanical limit to prevent the slider 3 from sliding accidentally, reducing the risk of the bolt separating from the clamping member 4, thereby improving the installation stability and operation safety.

[0027] When it is necessary to install the aluminum wall panel 1 on the exterior wall of a building, the staff first clamp the bolts for fixing in the two clamping members 4 on each slider 3 and ensure their stability and reliability. Subsequently, the operator adjusts the aluminum wall panel 1 to a position that fits the bracket and conducts a preliminary positioning to ensure the installation accuracy. Then, the drilling device is started to perform precise drilling operations on the bracket through the chute on the fixed ear 2.

[0028] After the drilling is completed, the staff pushes the slider 3 along the chute to the installation hole. Then, a wrench or power tool is used to apply a downward pressure and rotate the bolt, so that the bolt is smoothly screwed into the installation hole inside the bracket. During this process, the clamping member 4 generates a radial contraction under the extrusion of the bolt and is gradually received into the inside of the slider 3 until the bolt head is closely attached to the surface of the slider 3, completing the fastening connection at this point. The remaining connection points are all operated in this process in sequence until the entire aluminum wall panel 1 is firmly installed on the bracket. In this application, by pre-clamping the required bolts on the fixed ear 2 before installation, changing the installation order of the bolts, reducing the probability of the aluminum wall panel shifting when the staff tightens the bolts with one hand, and combining with the movable slider 3, the positioning and fastening of the bolt can be quickly achieved after the drilling is completed.

[0029] When the slider 3 moves along the chute on the fixed ear 2, it will drive the two clamping blocks 6 on it to slide synchronously. During this process, the clamping block 6 contacts and exerts an extrusion effect on the saw tooth block on the adjacent saw tooth rack 5. The clamping block 6 undergoes elastic deformation and deflection under the force. With the continuous movement of the slider 3 driving the clamping block 6, the clamping block 6 crosses the saw tooth block. Under the action of the elastic force, it rebounds and is embedded into the tooth groove of the adjacent saw tooth rack 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 clamping block 6 no longer receives the extrusion force from the saw tooth rack 5 and is stably clamped into the tooth groove of the saw tooth rack 5 under its own elastic force, forming a mechanical limit structure. Through the cooperation of the saw tooth rack 5 and the clamping block 6, it effectively prevents the slider 3 from sliding unexpectedly during the subsequent adjustment of the aluminum wall panel 1, thereby reducing the risk of the bolt on the slider 3 detaching from the clamping member 4 due to displacement and improving the stability and operation safety of the installation process.

[0030] Example 2 This embodiment discloses an external barrier for a building body, which is further improved on the basis of Embodiment 1.

[0031] As Figure 4 and Figure 6 shown, a ring gasket 8 is slidably connected in the middle through hole of the slider 3. The ring gasket 8 is made of an elastic material, and the inner radius of the ring gasket 8 is smaller than the radius of the threaded part of the bolt. An annular inclined surface is arranged inside the upper side surface of the ring gasket 8 to facilitate the entry of the bolt. The slider 3 is located inside the fixed ear 2, and the ring gasket 8 is located inside the slider 3, that is, the lower side surface of the slider 3 is higher than the lower side surface of the fixed ear 2, and the lower side surface of the ring gasket 8 is not lower than the lower side surface of the slider 3. When the slider 3 slides along the chute of the fixed ear 2, the ring gasket 8 does not contact the bracket, reducing the moving resistance of the slider 3 and reducing the wear of the ring gasket 8. A connecting ring 9 is fixedly connected to the upper side of the ring gasket 8. In this embodiment, the connecting ring 9 is fixedly connected to the two clamping members 4, and there is no connection relationship between the clamping members 4 and the slider 3. An elastic member 10 is arranged between the connecting ring 9 and the slider 3. The elastic member 10 is a tension spring, which is used to control the ring gasket 8 to be inside the slider 3. The elastic coefficient of the clamping member 4 is greater than the elastic coefficient of the elastic member 10, so that the elastic member 10 is stretched prior to the clamping member 4.

[0032] During the installation process, when the operator uses a wrench or power tool to apply downward pressure on the bolt and rotate it to gradually screw it into the installation hole of the bracket, the bolt head will continuously apply an extrusion force to the two clamping members 4. At this time, the two clamping members 4 push the ring gasket 8 to slide along the slider 3 through the connecting ring 9 until the ring gasket 8 is in close contact with the surface of the bracket. During this process, the elastic member 10 is stretched. As the bolt continues to penetrate into the installation hole, the bolt head further squeezes the clamping member 4. Since the ring gasket 8 is limited by the bracket and cannot move further at this time, the two clamping members 4 radially contract under the action of the extrusion force and are then received into the inside of the slider 3 until the bolt head is completely in contact with the surface of the slider 3, completing the fastening operation at this point. During this process, the inner side of the ring gasket 8 is elastically deformed by the extrusion of the outer wall of the bolt and is closely attached to the surface of the bolt, thereby realizing effective sealing of the connection part between the installation hole of the bracket and the bolt, significantly reducing the risk of external moisture infiltration, preventing bolt corrosion, improving the overall connection reliability and durability of the aluminum wall panel 1, and enhancing the stability and sealing performance of the installation structure.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
