Description

Technical Field

[0001] This application relates to the technical field of curtain walls, and in particular to an exterior curtain wall and a construction method. Background Art

[0002] An exterior curtain wall refers to the non-load-bearing exterior enclosure of a building, which is composed of panel materials and a support structure system, and is connected to the main building structure through a connecting device, having the ability of relative displacement or self-deformation.

[0003] In the related art, a curtain wall includes a wall body and a plurality of connecting plates. The wall body is located between two adjacent connecting plates. The connecting plates are fixed to the outer wall by bolts, and the wall body and the connecting plates are fixed by welding.

[0004] Since the exterior curtain wall can be installed on the outer wall of a high-rise building, if the high-rise building shakes, the curtain wall may vibrate with the shaking of the high-rise building, causing adjacent two curtain walls to vibrate or be squeezed, resulting in damage between the two curtain walls and affecting the use of the curtain wall. Summary of the Invention

[0005] In order to improve the problem that the curtain wall is easily damaged due to vibration, this application provides an exterior curtain wall and a construction method.

[0006] An exterior curtain wall provided by this application adopts the following technical solution: An exterior curtain wall includes a skeleton, a plurality of wall bodies and a plurality of connecting plates. The skeleton is fixed to the outer wall. The wall bodies are located between two adjacent connecting plates. A shock-absorbing part is provided on the side of the connecting plate away from the wall body. The connecting plate is slidably connected to the skeleton. A placement groove is formed on the skeleton, and a placement plate is provided on the wall body. The length of the placement groove is greater than the length of the placement plate; when the placement plate is located in the placement groove, the wall body is fixed to the skeleton.

[0007] By adopting the above technical solution, since the connecting plate is slidably connected to the skeleton and the length of the placement groove is greater than the length of the placement plate, both the wall body and the connecting plate can slide on the skeleton. When the high-rise building vibrates, the wall body and the connecting plate can move on the skeleton. At this time, the shock-absorbing part is located on the side of the connecting plate away from the wall body, so that the shock-absorbing part can buffer and damp the movement of the connecting plate, reducing the possibility of damage between adjacent two curtain walls, increasing the service life of the curtain wall, and avoiding the situation that the curtain wall is damaged due to vibration.

[0008] Optionally, two limiting springs are provided in the placement groove. A limiting block is provided on the surface of the limiting spring facing the placement plate. The limiting spring drives the limiting block to move towards the placement plate. The placement plate is located between the two limiting blocks.

[0009] By adopting the above technical solution, with the placement plate located between the two limit blocks, the two limit springs can drive the limit blocks to move towards the placement plate, enabling the limit blocks to restrict the movement of the placement plate in the placement groove. At the same time, through the support of the limit springs driving the limit blocks on the placement plate, the limit springs can play a buffering role for the placement plate, reducing large-scale movement of the wall on the skeleton. At the same time, the limit springs drive the placement plate to reset through the limit blocks, so that there is still a buffer space between the two curtain walls when the wall vibrates next time.

[0010] Optionally, a fixing plate is slidably connected to the connecting plate, and a fixing hole for placing the shock-absorbing part is formed on the fixing plate. When the shock-absorbing part is located in the fixing hole, the shock-absorbing part is fixed between the two connecting plates.

[0011] By adopting the above technical solution, with the shock-absorbing part located in the fixing hole, the fixing plate can protect the shock-absorbing part, enabling the shock-absorbing part to be protected by the fixing plate and the two connecting plates, reducing damage to the shock-absorbing part caused by external environmental factors.

[0012] Optionally, a limiting strip is provided on the limit block, a through hole for the limiting strip to pass through is formed on the skeleton, a limiting inclined surface is formed on the limiting strip, the distance between the limiting inclined surface and the connecting plate gradually increases along the direction from the limit block to the limit spring, the fixing plate is located on the moving path of the limiting inclined surface, and a moving strip is slidably connected to the connecting plate, and the moving strip is located on the moving path of the fixing plate. When the wall moves towards one of the connecting plates, the limiting strip pushes the fixing plate to protrude from the connecting plate through the limiting inclined surface, and at this time the moving strip protrudes from the connecting plate.

[0013] By adopting the above technical solution, when the wall slides towards one of the connecting plates, the limit block drives the limiting strip to move. Since the fixing plate is located on the moving path of the limiting inclined surface, the limiting strip drives the fixing plate to move through the limiting inclined surface, enabling the fixing plate to protrude from the connecting plate, and the fixing plate drives the moving strip to move, enabling the moving strip to protrude from the connecting plate, so that maintenance personnel can directly observe the movement of the wall during daily maintenance, enabling the maintenance personnel to maintain a certain curtain wall targeted and avoiding damage to the curtain wall due to long-term extrusion.

[0014] Optionally, a U-shaped elastic piece is provided on the side of the connecting plate away from the wall, and the fixing plate is located between the U-shaped elastic piece of one curtain wall and the U-shaped elastic piece of the other curtain wall. When the fixing plate protrudes from the connecting plate, the U-shaped elastic piece can abut against the U-shaped elastic piece of the connecting plate in the other curtain wall.

[0015] By adopting the above technical solution, with the fixing plate located between the U-shaped elastic piece and the U-shaped elastic piece of another curtain wall, when the two connecting plates move towards the fixing plate, the U-shaped elastic piece can be compressed, enabling the U-shaped elastic piece to buffer the fixing plate and the connecting plates.

[0016] Optionally, the wall is detachably connected between the two connecting plates. A connecting rod is rotatably connected to the connecting plate, and the connecting rod is rotatably connected to the fixing plate. There are two connecting rods on the fixing plate, one connecting rod is located on the connecting plate, and the other connecting rod is located on the connecting plate of another curtain wall; when the two connecting rods are parallel, the fixing plate does not protrude from the connecting plate.

[0017] By adopting the above technical solution, when the limiting spring drives the limiting block to reset, since the wall is detachably connected between the two connecting plates, the wall can drive the connecting plates to reset. There are two connecting rods rotatably connected to the connecting plate, and the connecting rods are rotatably connected to the fixing plate. The connecting plate drives the fixing plate to move through the connecting rods until the two connecting rods are parallel, enabling the fixing plate to reset and be located between the two U-shaped elastic pieces, making it difficult for the wind to directly blow the connecting plates to move when the wind is strong usually, reducing the possibility of the connecting plates shaking due to strong wind.

[0018] Optionally, a through hole is formed in the connecting plate, and a mounting block is slidably connected in the through hole. A mounting strip is provided on the mounting block, and the placement groove penetrates to the surface of the framework. The mounting strip can be located on one side where the placement groove penetrates; when the mounting strip is located in the placement groove, the mounting strip restricts the placement plate from detaching from the placement groove, and at this time the mounting block is located in the through hole.

[0019] By adopting the above technical solution, the staff slides the mounting block in the through hole to drive the mounting strip to move, so that the mounting strip can be disengaged from one side where the placement groove penetrates, thereby enabling the placement plate to be disengaged from the framework on one side where the placement groove penetrates, realizing the replacement of the wall; through the limitation of the placement plate by the mounting strip, the placement plate can be stably located on the framework, reducing the problem of the wall shaking caused by the placement plate being blown by the wind.

[0020] Optionally, a mounting elastic piece is provided on the limiting strip, and the mounting elastic piece can be inserted into the through hole; when the wall moves towards one side of the connecting plate, the mounting elastic piece is inserted into the through hole, and the mounting elastic piece restricts the movement of the mounting block in the through hole.

[0021] By adopting the above technical solution, when the wall moves towards the direction of one side connecting plate, the wall drives the limiting strip to move through the limiting block, so that the installation elastic sheet in the limiting strip is inserted into the perforation, realizing the limitation of the installation block by the installation elastic sheet, and enabling the installation strip to limit the placing plate more stably; when the wall moves towards one side, the installation elastic sheet limits the installation block, so that the installation block is not easy to move even during the shaking process, further enhancing the stability of the installation block in the connecting plate.

[0022] A construction method for an exterior curtain wall includes the following steps: S1. Measuring and setting out lines; S2. Installing post-embedded parts; S3. Installing the skeleton, and installing the wall and the connecting plate; S4. Cleaning.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. By sliding the connecting plate on the skeleton, and the length of the placing groove is greater than the length of the placing plate, both the wall and the connecting plate can slide on the skeleton. When the high-rise building vibrates, the wall and the connecting plate can move on the skeleton. At this time, the shock-absorbing part is located on the side of the connecting plate away from the wall, so that the shock-absorbing part can buffer and absorb the movement of the connecting plate, reducing the possibility of damage between adjacent two curtain walls, increasing the service life of the curtain wall, and avoiding the situation that the curtain wall is damaged due to vibration.

[0024] 2. When the wall slides towards the direction of one side connecting plate, the limiting block drives the limiting strip to move. Since the fixed plate is located on the moving path of the limiting inclined surface, the limiting strip drives the fixed plate to move through the limiting inclined surface, so that the fixed plate can protrude from the connecting plate, and the fixed plate drives the moving strip to move, enabling the moving strip to protrude from the connecting plate, so that the daily maintenance personnel can directly observe the movement of the wall, enabling the maintenance personnel to maintain a certain curtain wall targeted, and avoiding the situation that the curtain wall is damaged due to long-term extrusion.
