Description

Technical Field

[0001] This invention relates to the field of decorative wall panel technology, and more particularly to unitized integrated decorative wall panels. Background Technology

[0002] In recent years, with the promotion of prefabricated building technology and the widespread application of steel structure building systems, building envelope structures have gradually shifted from traditional wet construction methods to industrialization and modularization. Especially for multi-story and high-rise steel frame buildings, the main approach is to use bolted-welded or hinged connections between steel beams and columns to form a load-bearing skeleton, and then use external curtain walls or unitized wall panels to achieve the external envelope and decorative functions. Compared to traditional masonry walls, unitized decorative wall panels have advantages such as shorter construction cycles, higher assembly precision, and less on-site work, and are therefore widely used in office buildings, apartments, and public buildings. However, in existing unitized wall panel systems, the exterior wall panels are usually directly fixed to the steel structure frame via connectors. When the building's exterior wall panels are exposed to high temperatures or low temperatures, the thermal expansion and contraction effect can easily lead to stress concentration and uneven displacement between the exterior wall panels and the internal wall support structure, causing problems such as joint cracking, connector fatigue, or exterior surface deformation.

[0003] In existing technologies, although some prefabricated wall panels have attempted to alleviate thermal stress by adding elastic gaskets, expansion joints, or sliding connectors at the keel structure or connection nodes, these methods are mostly passive adaptations to structural expansion and contraction and cannot achieve dynamic compensation and adjustment for the thermal expansion and contraction process. Especially when there is no effective temperature response and traction coordination mechanism between the exterior wall panel and the keel, when temperature changes cause the exterior wall panel to expand or contract, mutual compression or separation will occur within the wall system. Under long-term action, this can easily lead to problems such as reduced wall stability, deformation of the supporting keel, or loosening and delamination of the exterior wall panel. Therefore, it is necessary to design a unitized decorative integrated wall panel to solve the above problems. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the above-mentioned modular decorative wall panels, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a unitized decorative integrated wall panel, which is suitable for solving the problem that when the temperature changes cause the exterior wall panel to expand or contract, the wall system will experience mutual compression or separation, which can easily lead to reduced wall stability, deformation of the supporting keel, or loosening and delamination of the exterior wall panel under long-term action.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a unitized decorative integrated wall panel, comprising: An integrated wall panel unit comprises two symmetrically erected structural steel columns within the floors of a steel structure building, and an inner wall panel and an outer wall panel erected between the two steel structural columns. The hinged support unit includes multiple wall panel keels that are evenly arranged longitudinally between the inner wall panel and the outer wall panel. Two steel columns are arranged longitudinally and crosswise in the gap between the inner wall panel and the outer wall panel. Each steel column is fixedly equipped with a welding seat, and each end of the steel column is fixedly welded to the corresponding welding seat. The thermal compensation unit is used to compensate for the thermal expansion and contraction of the exterior wall panels and the wall panel joists.

[0008] As a preferred embodiment of the unit-type integrated decorative wall panel of the present invention, the heat compensation unit includes multiple temperature sensing cylinders fixedly installed on one side of the inner wall of the wall panel keel located at the center, and piston discs that are sealed and slidably connected to the inner wall of the corresponding temperature sensing cylinders. A chuck is provided at the intersection of the two steel columns. A piston rod is fixedly connected between the piston disc and the chuck. The side of the piston disc away from the piston rod and the inner end wall of the temperature sensing cylinder are filled with a low-boiling-point evaporating liquid. The heat compensation unit also includes a traction gap-retaining component for traction of the outer wall panel.

[0009] As a preferred embodiment of the unit-type integrated decorative wall panel of the present invention, the traction gap-retaining component includes a plurality of push cylinders that are disposed through one side of the wall panel keel and slidably connected to the side wall of the wall panel keel. The side of the push cylinder away from the outer wall panel is fixedly connected to a chuck. The side of the outer wall panel close to the wall panel keel is fixedly provided with a plurality of evenly distributed push rods, and the end of each push rod away from the outer wall panel is inserted into the corresponding push cylinder.

[0010] As a preferred embodiment of the unit-type decorative integrated wall panel of the present invention, the portion of the push rod located in the push cylinder is configured as a gradient stepped shape, and the push cylinder is provided with a gradient stepped groove that matches the end of the push rod. Two sets of evenly distributed second wedge rings are symmetrically arranged on the outer wall of the push cylinder, and a first wedge ring that matches the second wedge ring is fixedly arranged on the inner wall of the gradient stepped groove.

[0011] As a preferred embodiment of the unit-type integrated decorative wall panel of the present invention, each of the steel columns is fixedly connected to the outer wall panel with traction bars at both ends, and each traction bar penetrates the corresponding wall panel keel sidewall.

[0012] As a preferred embodiment of the unit-type integrated decorative wall panel of the present invention, each of the traction ribs is fixedly connected to a reinforcing platform at its end and the outer wall panel, wherein the diameter of the reinforcing platform at one end near the outer wall panel is larger than the diameter of the other end of the reinforcing platform.

[0013] As a preferred embodiment of the unit-type integrated decorative wall panel of the present invention, each piston rod is fitted with a corresponding return spring, and the return spring is located between the chuck and the temperature sensing cylinder.

[0014] As a preferred embodiment of the unit-type decorative integrated wall panel of the present invention, the chuck is configured as a circle, and multiple push cylinders are arranged in a ring along the axis of the chuck.

[0015] As a preferred embodiment of the unitized decorative integrated wall panel of the present invention, each of the steel columns includes a long steel column and a short steel column, and each long steel column and its corresponding short steel column are connected by a corresponding turnbuckle.

[0016] As a preferred embodiment of the unit-type integrated decorative wall panel of the present invention, the inner wall panel and the outer wall panel are fastened to the wall panel keel by multiple sets of evenly distributed self-tapping screws, and the wall panel keel is slidably installed with a sliding threaded sleeve that matches the self-tapping screw on the outer wall panel.

[0017] The beneficial effects of this invention are as follows: When the exterior wall panel and its supporting frame are exposed to strong sunlight and their temperatures rise, the thermal compensation unit can actively pull the exterior wall panel slightly, proactively leaving a gap between the exterior wall panel and its supporting frame to accommodate expansion. After the temperature drops at night, the thermal compensation unit can again pull the exterior wall panel closer to its supporting frame, proactively narrowing the gap between the exterior wall panel and its supporting frame, ensuring that the exterior wall panel and its supporting frame are always in contact. This effectively solves the problem that when the exterior wall panel expands or contracts due to temperature changes, the internal wall system may experience mutual compression or separation, which can easily lead to reduced wall stability, deformation of the supporting frame, or loosening and delamination of the exterior wall panel over a long period of time.

Detailed Implementation

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0023] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0024] Example 1 Reference Figures 1-4 According to one embodiment of the present invention, a unitized decorative integrated wall panel is provided, including: an integrated wall panel unit 100, a hinged support unit 200, and a thermal compensation unit 300.

[0025] The integrated wall panel unit 100 includes two symmetrically erected structural steel columns 101 within the steel structure building floors, and an inner wall panel 102 and an outer wall panel 103 erected between the two steel structural columns. It should be noted that the outer wall panel 103 can be made of materials with good light transmission performance, such as panels, composite panels, dry-hanging ceramic tile lightweight concrete panels, or glass panels. Secondly, the hinged support unit 200 includes a plurality of wall panel keels 201 that are evenly arranged longitudinally between the inner wall panel 102 and the outer wall panel 103. Two steel columns are arranged longitudinally and intersectingly in the gap between the inner wall panel 102 and the outer wall panel 103. It should be noted that in this invention, each wall panel keel 201 has a strip groove for slight movement of the steel column at the connection between its side wall and the steel column. Each steel column is fixedly provided with a welding seat 206, and each end of the steel column is fixedly welded to the corresponding welding seat 206. Furthermore, each steel column includes a long steel column 203 and a short steel column 204, and each long steel column 203 and the corresponding short steel column 204 are connected by a corresponding turnbuckle 205. It should be noted that the turnbuckle 205, also known as a "tensioning bolt" or "turnbuckle screw," is a connecting fastener used to tighten, adjust, and fix the relative position of components. Its main structure includes a sleeve with internal threads at both ends, and a left-hand threaded screw and a right-hand threaded screw that cooperate with it. By rotating the sleeve, the screws at both ends can be moved inward or outward simultaneously, thereby achieving the tensioning or loosening adjustment of the connected components. In building construction, turnbuckles are often used for tensioning connections between steel cables and steel components. In this embodiment of the invention, during construction, installers can flexibly adjust the connection tightness between the long steel column 203 and the short steel column 204 by rotating the turnbuckle 205 to achieve fine-tuning of the overall structure's length and stress balance.

[0026] Furthermore, both the inner wall panel 102 and the outer wall panel 103 are fastened to the wall panel keel 201 by multiple sets of evenly distributed self-tapping screws 202, and the wall panel keel 201 is slidably installed with a sliding threaded sleeve 207 that matches the self-tapping screws 202 on the outer wall panel 103; the sliding threaded sleeve 207 can slide on the side wall of the wall panel keel 201, ensuring that the self-tapping screws 202 are threadedly connected to the wall panel keel 201 while also moving a certain distance relative to the wall panel keel 201 with the outer wall panel 103.

[0027] Reference Figure 1 and Figure 2 According to the construction drawings, the exterior wall panel 103 and the interior wall panel 102 are fastened to both sides of the wall panel keel 201 with self-tapping screws 202. They are pre-processed in the source factory to form a unit wall panel with "secondary support". After being transported to the construction site, the two ends of the pre-installed steel column are welded to the welding seat 206 on the steel structure column 101 on the steel structure building site. This realizes the rapid installation of the unit decorative wall panel and the steel structure. The factory prefabrication and the on-site steel structure construction are carried out simultaneously, which greatly reduces the amount of on-site work and procedures. On-site installation only requires hoisting. The construction speed is fast. All unit decorative wall panels are produced in the factory in a standardized and mechanized manner, with controllable quality and high precision. This solves the problem of difficulty in ensuring construction quality due to the difference in the ability of on-site construction personnel. This invention innovatively combines the "hinged frame support system" and the "unit wall structure system" into a whole unit decorative wall panel, which is structurally safe and reliable.

[0028] Secondly, the thermal compensation unit 300 is used to compensate for the thermal expansion and contraction of the external wall panel 103 and the wall panel keel 201.

[0029] During use, when the exterior wall panel 103 installed on the exterior surface of the steel structure building is exposed to strong sunlight, and the temperature of the exterior wall panel 103 and the wall panel keel 201 rises, the heat compensation unit 300 can actively pull the exterior wall panel 103 to move slightly, actively leaving a gap between the exterior wall panel 103 and the wall panel keel 201 to accommodate expansion. After the temperature drops at night, the heat compensation unit 300 can again pull the exterior wall panel 103 closer to the wall panel keel 201, actively narrowing the gap between the exterior wall panel 103 and the wall panel keel 201, ensuring that the exterior wall panel 103 and the wall panel keel 201 are always in contact. This effectively solves the problem that when the exterior wall panel 201 expands or contracts due to temperature changes, the internal wall system may experience mutual compression or separation, which can easily lead to reduced wall stability, deformation of the supporting keel, or loosening and delamination of the exterior wall panel under long-term action.

[0030] Example 2 Reference Figure 3-10The difference from Embodiment 1 is that the thermal compensation unit 300 includes multiple temperature sensing cylinders 302 fixedly installed on one side of the inner wall of the wall panel keel 201 located at the center, and piston discs 303 sealed and slidably connected to the inner wall of the corresponding temperature sensing cylinders 302. A chuck 301 is clamped at the intersection of the two steel columns. A piston rod 304 is fixedly connected between the piston disc 303 and the chuck 301. Each piston rod 304 is fitted with a corresponding return spring 305, and the return spring 305 is located between the chuck 301 and the temperature sensing cylinder 302. The return spring 305 is used to assist the chuck 301 in driving the two steel columns to return to their original positions. The side of the piston disc 303 away from the piston rod 304 and the inner end wall of the temperature sensing cylinder 302 are filled with a low-boiling-point evaporating liquid. The thermal compensation unit 300 also includes a traction gap assembly 306 for traction of the outer wall panel 103.

[0031] It should be noted that, in this embodiment of the invention, the low-boiling-point evaporating liquid is a thermosensitive expansion medium capable of undergoing a phase change at a relatively low temperature. It is used to generate expansion pressure in response to changes in ambient temperature to drive the piston disc 303. To ensure that the low-boiling-point evaporating liquid in the temperature sensing cylinder 302 can respond sensitively to changes in ambient temperature and generate stable expansion pressure, the low-boiling-point evaporating liquid is selected from one or more of the following substances: diethyl ether, difluoromethane, trifluoroethanol, or acetone. Its specific physical properties and applicable scope are as follows: Diethyl ether: Boiling point is 34.6℃. When the ambient temperature rises to 25~35℃, the vapor pressure of diethyl ether rises rapidly. It can produce a significant vaporization expansion effect in a closed space. It is suitable for thermal response compensation in low-temperature environments. It will not leak when used in a sealed cavity and has no significant harm to the human body and the environment. Difluoromethane: It can produce relatively significant pressure changes in the range of -30 ℃ to 30 ℃. It has a high expansion coefficient and is suitable for compensation systems that require extremely sensitive temperature response. It is often used as a refrigerant and has no cumulative harm to the human body. Trifluoroethanol exhibits stable linear expansion behavior between 40 and 70 °C. Its vapor pressure changes smoothly with temperature, and it can maintain the controllability of the compensation system in high-temperature environments. It has mild irritation, volatilizes slowly at room temperature, and is not a highly toxic substance. It is safe and reliable for use in closed systems. Acetone: Boiling point is 56℃. It can generate significant vaporization expansion pressure in the temperature range of 30-50℃. The heating rate is linearly related to the volume expansion. It has a fast response speed, low toxicity, is biodegradable, and environmentally friendly. It will not cause harm to people in a closed structure. In practical applications, the low-boiling-point evaporator can be proportionally adjusted according to the ambient temperature difference of the building location. For example, in cold, high-latitude regions, a mixture of diethyl ether and difluoromethane can be preferred to enhance low-temperature sensitivity, while in hot regions, a mixture of trifluoroethanol and acetone can be used to improve high-temperature expansion stability. The evaporator maintains good phase change stability and pressure recovery performance within the temperature range of -20 ℃ to 60 ℃, and will not leak or produce toxicity under sealed operating conditions.

[0032] like Figure 5 As shown, the traction gap-retention assembly 306 includes multiple push cylinders 306a that are disposed through one side of the wall panel keel 201 and slidably connected to the side wall of the wall panel keel 201. The side of the push cylinder 306a away from the outer wall panel 103 is fixedly connected to the chuck 301. The chuck 301 is circular, and the multiple push cylinders 306a are arranged in a ring along the axis of the chuck 301. Multiple sets of evenly distributed push rods 306b are fixedly disposed on the side of the outer wall panel 103 near the wall panel keel 201, and the end of each push rod 306b away from the outer wall panel 103 is inserted into the corresponding push cylinder 306a.

[0033] Furthermore, such as Figure 8 As shown, the portion of push rod 306b located in push cylinder 306a is configured as a gradually stepped shape, and push cylinder 306a has a gradually stepped groove that matches the end of push rod 306b. Two sets of evenly distributed second wedge rings 306d are symmetrically arranged on the outer wall of push cylinder 306a, and a first wedge ring 306c that matches the second wedge rings 306d is fixedly arranged on the inner wall of the gradually stepped groove. The axial cross-section of the first wedge ring 306c and the second wedge ring 306d is set as teeth. The toothed push rod 306b end can move slightly along the axial direction of the push rod 306b in the gradually stepped groove. Whether it is due to heat or cold, when the end of the push rod 306b moves relative to the push cylinder 306a, the first wedge ring 306c and the second wedge ring 306d will lock together, thereby ensuring that the exterior wall panel 103 and the wall panel keel 201 can be locked tighter and tighter under the condition of "thermal expansion and contraction", which improves the tightness of the fit between the exterior wall panel 103 and the wall panel keel 201.

[0034] Reference Figure 7-8During use, as sunlight passes through the transparent outer wall panel 103 and irradiates the gas in the "cavity" formed by the inner wall panel 102 and the outer wall panel 103, causing the gas temperature to rise, the low-boiling-point evaporating liquid in the temperature sensing cylinder 302 expands due to heat, thereby pushing the piston disc 303 and driving the piston rod 304 to squeeze the chuck 301. The chuck 301 then pushes the push cylinder 306a toward the outer wall panel 103. The second wedge-shaped ring 306d on the side wall of the push rod 306b, which is engaged with the gradually stepped groove in the push cylinder 306a, first... The first wedge-shaped ring 306c on the inner wall of the push cylinder 306a is tightly engaged, which indirectly improves the connection stability between the wall panel keel 201 and the outer wall panel 103. As the push cylinder 306a drives the push rod 306b to move continuously toward the outer wall panel 103, the outer wall panel 103 gradually moves away from the wall panel keel 201, thereby actively reserving the gap required for the "thermal expansion" of the wall panel keel 201 and the outer wall panel 103. Conversely, when the temperature of the "cavity" between the outer wall panel 103 and the inner wall panel 102 decreases due to changes in the external temperature, at this time... The low-boiling-point evaporator inside the temperature sensing cylinder 302 is cooled and changes from a gaseous state back to a liquid state. With the assistance of the return spring 305, the piston rod 304 pulls the chuck 301 to move towards one side of the temperature sensing cylinder 302. The chuck 301 then drives multiple push cylinders 306a to move towards one side of the chuck 301. During the movement of the push cylinders 306a, the first wedge ring 306c set on the inner wall of the push cylinder 306a first tightly engages with the second wedge ring 306d set on the side wall of the push rod 306b. As the push cylinder 306a continues to move, the push... The cylinder 306a then pulls the outer wall panel 103 toward the wall panel keel 201 via the push rod 306b, so that the outer wall panel 103 and the wall panel keel 201 come into contact. This can actively compensate and adjust the outer wall panel 103 and the wall panel keel 201 during thermal expansion and contraction. This effectively solves the problem that when the outer wall panel 103 expands or contracts due to temperature changes, the wall system will experience mutual compression or separation, which can easily lead to reduced wall stability, deformation of the supporting keel, or loosening and delamination of the outer wall panel under long-term action.

[0035] Preferred, such as Figure 3 As shown, each steel column has a traction bar 307 fixedly connected to both ends of the outer wall panel 103, and each traction bar 307 is installed through the side wall of the corresponding wall panel keel 201. A reinforcing platform is fixedly connected between the end of each traction bar 307 and the outer wall panel 103. The diameter of the end of the reinforcing platform near the outer wall panel 103 is larger than the diameter of the other end of the reinforcing platform. The setting of the reinforcing platform increases the contact area between the traction bar 307 and the outer wall panel 103, and further improves the connection stability between the traction bar 307 and the edge of the outer wall panel 103.

[0036] like Figure 9As shown, when the outer wall panel 103 and the wall panel keel 201 expand due to heat, the piston rod 304 pushes the chuck 301 to press against the junction of the two steel columns. As the hinge of the two steel columns is subjected to force, the traction ribs 307 set on the side wall end wall of the steel column are pulled outward from the edge of the outer wall panel 103, so that the edge of the outer wall panel 103 and the wall panel keel 201 are reserved with sufficient gap, so that the outer wall panel 103 is subjected to force evenly. This effectively solves the defect of the outer wall panel 103 edge warping or bulging caused by the mutual compression between the edge of the outer wall panel 103 and the edge of the wall panel keel 201 when the edge of the outer wall panel 103 expands due to heat. like Figure 10 As shown, when the outer wall panel 103 and the wall panel keel 201 shrink due to cold, the piston rod 304 pulls the chuck 301, causing the hinge joint of the two steel columns to move towards one side of the inner wall panel 102. The traction rib 307 set at the end of the side wall of the steel column follows the chuck 301 and moves the edge of the outer wall panel 103 towards the inner wall panel 102, so that the edge of the outer wall panel 103 abuts against the side wall of the wall panel keel 201, so that the outer wall panel 201 is evenly stressed. This effectively solves the defect that the gap between the edge of the outer wall panel 103 and the wall panel keel 201 increases and the stability decreases due to shrinkage.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
