Description

Technical Field

[0001] This invention relates to the field of construction facilities technology, and in particular to a building envelope structure for residential buildings and its usage method. Background Technology

[0002] Construction site hoardings are an important measure to effectively isolate the construction site from the external environment and ensure that the construction site forms a closed and orderly space. These hoardings can be walls built with various masonry materials or sturdy enclosures made of various prefabricated panels, aiming to provide a safe and standardized construction environment.

[0003] For example, patent number CN111155827B discloses a building envelope structure for a building construction project, belonging to the technical field of building construction facilities. It includes multiple bases, each base having two columns hinged to the base. The base has a first fixing member for fixing the columns to a perpendicular position. Each base has a cavity with a covering cloth inside. One side of the covering cloth is fixedly placed in the cavity. The base has a strip opening for the other side of the covering cloth to move out. A movable strip is fixedly placed on the outer edge of the covering cloth. The two ends of the movable strip have second fixing members for fixing the movable strip to the ends of the columns away from the base. When the building envelope is not needed, the covering cloth is moved into the cavity, causing the hinge point of the column on the base to rotate, so that the column rotates to a state of being in contact with the base. This reduces the space occupied by the entire building envelope and facilitates the transportation of each building envelope.

[0004] For example, patent number CN118532082B discloses an enclosure structure for building construction, including vertical columns with a bottom support assembly fixed to their lower ends. It also includes enclosure panels, with multiple panels sequentially arranged on one side of the vertical column. The vertical column is connected to the multiple enclosure panels via a transmission assembly. The enclosure panel closest to the vertical column is rotatably connected to the vertical column. A retraction control assembly is installed on the vertical column to drive the retraction and rotation of the enclosure panel closest to the vertical column. When the retraction control assembly drives the retraction and rotation of the enclosure panel closest to the vertical column, the transmission assembly drives the remaining enclosure panels to retract and rotate synchronously. This invention is simple to operate, highly efficient in its coordinated retraction and rotation, and can quickly complete enclosure operations.

[0005] Regarding the above description, the applicant believes that the following problems exist: Although existing building envelope structures such as CN118532082B can be retracted and extended simultaneously, they rely on complex internal gear linkages and manual cranks, which are complex in structure, easily damaged, and laborious to operate; while another type, such as CN111155827B, relies entirely on manual labor to erect the columns one by one, pull out the covering cloth and fix it, which is cumbersome and inefficient. Neither of them can achieve the efficient deployment of "one person pulling, overall automatic forming", and both have the common problems of complex structure, many operation steps and low deployment efficiency. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention aims to provide a building envelope structure for building construction projects and its usage method, which realizes rapid deployment and folding by a single person, and has the functions of simple and reliable structure, compact storage volume, stable and durable on site, and independent replacement of each component. It alleviates the problems of low deployment efficiency, complex and easily damaged structure, and difficult maintenance in the prior art, improves construction efficiency, reduces use and maintenance costs, and enhances environmental adaptability.

[0007] The objective of this invention is achieved through the following technical solution: A building envelope structure for a building construction project includes a frame, and multiple frames are sequentially connected by an internal scissor cross-link structure to form a retractable enclosure body. The first movable column and the second movable column are fixedly connected to the leftmost frame and the second movable column is fixedly connected to the rightmost frame. The bottom of the first movable column and the second movable column are respectively fixedly connected to lockable casters. A enclosure assembly is provided on both sides of an enclosure body composed of multiple frames. Each enclosure assembly consists of multiple modular single enclosure panels, and each single enclosure panel is composed of multiple panels connected by hinges. A windproof component, comprising a windproof rod rotatably connected to the side of a frame, wherein a second fixing block is provided at the end of the windproof rod, and a second fixing hole is provided on the second fixing block; The bottom two ends of the frame are provided with first fixing blocks, and the first fixing blocks are provided with first fixing holes; A fixing plate is rotatably connected to the first movable column. The fixing plate is used to fix the enclosure structure during shrinkage and transfer. Two round rods are provided at the other end of the fixing plate. Limiting blocks are fixedly connected to the ends of the two round rods. Two first buckles are fixedly connected to the lower outer side of the first movable column. Two second buckles are fixedly connected to the top of the second movable column. A third buckle is also provided at the upper end of the side of the frame.

[0008] In one alternative implementation, auxiliary casters are spaced apart at the bottom of the frame.

[0009] In one optional embodiment, cylindrical connecting sections are provided at both ends of the plate body, and the plate body located at the outermost edge on the left and right sides is provided with a cylindrical connecting section at one end and a connector at the other end. The single enclosure plate is detachably connected to the connecting groove opened on the frame through the connector. A first baffle is provided at the bottom of the connecting groove, and a drainage hole is provided on the first baffle that communicates with the connecting groove.

[0010] In one optional embodiment, the length of the hinge is greater than the length of a single plate. The hinge consists of two mating cylindrical grooves that match the cylindrical connecting section, allowing two adjacent plates to unfold to approximately 180 degrees or retract to be parallel and fitted together. A second baffle is provided at the bottom of the hinge.

[0011] In one optional embodiment, the first buckle is used to lock the two round rods when the fixing plate is stored in the unfolded state of the enclosure structure; the second buckle is used to lock the two round rods and make the limiting block lock the second buckle to prevent the enclosure structure from unfolding when the enclosure structure is retracted and transported; and the third buckle is used to retract and fix the windproof rods when the windproof components are not used.

[0012] In one optional embodiment, the frame, scissor-type cross linkage structure, first moving column, second moving column, fixing plate, round rod, limiting block, first buckle, second buckle, third buckle, hinge, windproof rod, first fixing block and second fixing block are made of stainless steel or aluminum alloy, or have their surfaces coated with an anti-corrosion coating.

[0013] In one optional embodiment, the plate is a color steel plate, a galvanized steel plate, or an aluminum alloy plate.

[0014] A method for using the building envelope of a building construction project, characterized by comprising a deployment step: S1: Move the building envelope, which is in a fully folded and locked state, to the target location; S2: Release the locking between the fixing plate and the second buckle, and then engage the first buckle to lock it; S3: Lock the locking universal wheel of the first moving column (3), pull or push the second moving column (4) so ​​that the enclosure body can be opened synchronously through the scissor cross linkage structure (2) and all single enclosure panels (6) can be opened synchronously to form a continuous enclosure surface; S4: Lock the locking caster of the second moving column (4), and then fix the enclosure body to the ground through the first fixing block; S5: When it is necessary to enhance wind resistance, release the windproof rod from the third buckle and rotate it to the oblique support position, and fix it to the ground by the second fixing block.

[0015] In one optional implementation, the method further includes a collection and transfer step: R1: Release all ground fixation, retract the windproof rod and secure it to the third buckle; R2: Release the fixing plate from the first latch; R3: Push the second moving column toward the first moving column so that the enclosure body and the single enclosure panel fold together synchronously; R4: Rotate the fixing plate above the second moving column so that the round rod is engaged in the second buckle and locked by the limiting block; R5: Transfer the locked overall structure.

[0016] In one optional embodiment, the enclosure also includes a panel replacement step: when the enclosure body is in a fully unfolded, partially unfolded, or fully folded state, the damaged single panel is removed from the connecting slot of the frame and replaced with a good single panel.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the built-in scissor-type cross linkage structure and the cooperation of the first and second movable columns at both ends, the entire enclosure structure can be synchronously and smoothly deployed or folded by a single person pulling from one end. This alleviates the problems of laborious operation or cumbersome manual assembly steps that rely on complex transmission mechanisms in existing technologies, greatly improves deployment and withdrawal efficiency, reduces labor intensity, and enables rapid deployment by one person.

[0018] 2. By using a modular single enclosure panel made up of multiple panels connected by special hinges, and the detachable hook design of the single enclosure panel to the side connection groove of the frame through the connector, the rapid modular installation of the enclosure surface and the independent replacement of damaged single enclosure panels under any condition are achieved. This alleviates the problems of difficult maintenance of existing rigid fences and poor protection of flexible fences, significantly improves the maintainability and life-cycle economy of the enclosure system, and ensures the rigidity and continuity of the enclosure surface.

[0019] 3. By setting a rotatable fixed plate and its end rod and limiting block on the first movable column, and cooperating with the first buckle and the second buckle set on the two movable columns, the integrated effect of neatly storing the fixed plate when in the unfolded working state and reliably locking the overall structure when in the folded transportation state is achieved. This alleviates the problem that the movable fence is easy to loosen during transportation and that the external parts are inconvenient when unfolded, making the management of the structure convenient and reliable in both states.

[0020] 4. By using a windproof bar that can be rotatably stored in the third buckle and can be unfolded and fixed by the second fixing block, combined with the first fixing block at the bottom of the frame, the enclosure structure can be flexibly selected to enhance stability according to site conditions such as wind load. This alleviates the problem of insufficient wind resistance or inconvenient reinforcement methods of existing enclosures. While providing strong wind resistance, it also ensures the simplicity of the structure when not in use.

[0021] 5. By specifying that the main structural components such as the frame, movable columns, fixed plates, buckles, hinges, and windproof rods are made of stainless steel or aluminum alloy or coated with anti-corrosion coatings, and that the plates are made of color steel plates, galvanized steel plates, or aluminum alloy plates, the entire enclosure structure achieves excellent corrosion resistance and durability in humid and dusty construction environments, alleviating the problem of easy rust and damage to metal components on construction sites, and reducing the frequency of maintenance and replacement costs during long-term use.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Unless otherwise specified, the materials and equipment used in this embodiment are commercially available. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0025] Please refer to Figure 1-8 A building envelope structure for a building construction project, wherein the retractable frame assembly is composed of multiple parallel frames 1. In this embodiment, the frame 1 is preferably a rectangular frame welded from rectangular steel pipes. All frames 1 are sequentially hinged together by a scissor-type cross-link structure 2 set inside it. The scissor-type cross-link structure 2 consists of multiple sets of X-shaped links hinged at the middle intersection point by pins, and its two ends are respectively hinged to two adjacent frames 1 by pins. This structure ensures that when a pulling or pushing force is applied to both ends of the frame assembly, all frames 1 can be synchronously and equidistantly extended or retracted to form a stable telescopic movement.

[0026] In a preferred embodiment of the present invention, a first movable column 3 and a second movable column 4 are fixedly connected to both ends of the frame assembly, respectively. Specifically, the leftmost frame 1 is fixedly connected to the first movable column 3, and the rightmost frame 1 is fixedly connected to the second movable column 4. Lockable casters 5 are respectively installed at the bottom of the first movable column 3 and the second movable column 4. In order to provide better support during movement and unfolding and to prevent the middle frame 1 from sag, auxiliary casters 27 can be installed at intervals at the bottom of some frames 1, especially the bottom of the middle and near the middle frames 1.

[0027] In a preferred embodiment of the present invention, the enclosure panel assembly is disposed on the front and rear sides of the enclosure body composed of multiple frames 1. Each enclosure panel assembly is composed of multiple modular single enclosure panels 6 arranged along the telescopic direction. Each single enclosure panel 6 is formed by multiple panels 7 being sequentially hinged together by special hinges 8. In this embodiment, the panels 7 are rectangular and preferably made of color steel plate, galvanized steel plate or aluminum alloy plate, which has the characteristics of being lightweight, high strength and corrosion resistant. The two ends of the panels 7 are vertically folded to form cylindrical connecting sections 9. The panels 7 located at the outermost edges on the left and right sides of the single enclosure panel 6 have a special structure: one end of the panel also has a cylindrical connecting section 9 for hinged connection with the adjacent panel 7; the other end is provided with an outwardly protruding connector 10.

[0028] In a preferred embodiment of the present invention, a connecting groove 11 is vertically provided on the side of the frame 1 corresponding to the installation position of each single panel 6. The single panel 6 is inserted into the connecting groove 11 on the corresponding frame 1 from top to bottom through the connectors 10 on its two side edge plates 7, thereby achieving quick and detachable hanging. This design allows any single panel 6 to be removed or installed individually without affecting other components. A first baffle 12 is welded or riveted to the bottom of the connecting groove 11. The first baffle 12 is provided with a drainage hole 13 for draining rainwater that may enter the connecting groove 11.

[0029] In a preferred embodiment of the present invention, the hinge 8 is a key component, and its length is slightly greater than the height of a single plate 7. Two adjacent cylindrical grooves 14 with the same opening are machined on the main body of the hinge 8. These two cylindrical grooves 14 match the cylindrical connecting sections 9 at the ends of two adjacent plates 7, so that the cylindrical connecting sections 9 can be nested in the cylindrical grooves 14 and rotate freely. Through this structure, the two adjacent plates 7 can rotate relative to each other around the hinge 8. The rotation range is designed to be close to 180 degrees (i.e., approximately coplanar) from when the two plates 7 are fully folded and parallel to each other to when they are fully unfolded. A second baffle 15 is welded or riveted to the bottom of the cylindrical groove 14.

[0030] In a preferred embodiment of the present invention, the windproof assembly includes a windproof rod 16 rotatably connected to part or all of the side of the frame 1. A second fixing block 17 is fixed to the end of the windproof rod 16. The second fixing block 17 has a second fixing hole 18 for driving in a steel rod or anchor bolt. When the windproof function is not needed, the windproof rod 16 can be rotated and retracted and fixed to the side of the frame 1 by a third buckle 26. The third buckle 26 is welded or bolted to the upper end of the side of the frame 1. In order to firmly fix the unfolded frame assembly to the ground, a first fixing block 19 is welded to both ends of the bottom of each frame 1. The first fixing block 19 has a first fixing hole 20 for driving in a steel rod or anchor bolt.

[0031] In a preferred embodiment of the present invention, a fixed plate 21 is rotatably connected to the first movable column 3 via a hinge or a pivot. Two parallel round rods 22 are vertically welded to the free end of the fixed plate 21, and a limiting block 23 with a slightly larger diameter is welded to the end of the two round rods 22. Two first buckles 24 are fixed on the lower outer surface of the first movable column 3, and two second buckles 25 are fixed on the top of the second movable column 4. The first buckles 24, the second buckles 25 and the third buckles 26 are preferably elastic stainless steel buckles, and their openings are slightly smaller than the diameter of the round rods 22 or the windproof rods 16, so as to achieve clamping and fixing through elastic deformation.

[0032] In a preferred embodiment of the present invention, when the enclosure structure is fully extended and in working condition, the fixing plate 21 is considered a redundant component. At this time, it can be rotated so that its two round rods 22 can be engaged in the first buckle 24 on the first moving column 3, thereby making the fixing plate 21 tightly attached to the first moving column 3 and fixed in place, keeping the site clean. When the enclosure structure is fully folded and ready for transportation, it is necessary to prevent it from being accidentally unfolded due to bumps during transportation. At this time, the fixing plate 21 is released from the first buckle 24 and rotated above the second moving column 4, so that its two round rods 22 are aligned and forcefully engaged in the second buckle 25. Since the end of the round rod 22 has a limiting block 23 with a diameter larger than the buckle opening, after being engaged, the limiting block 23 will be engaged on the outside of the second buckle 25, forming a reliable anti-loosening lock, thereby locking the first moving column 3, the second moving column 4 and all the intermediate frames 1 in the folded state into a solid whole. The third buckle 26 is specifically designed to retract and fix the windproof rod 16 to the side of the frame 1 in non-windy weather or when no additional wind protection is required, so as to prevent it from shaking.

[0033] In a preferred embodiment of the present invention, the frame 1, the scissor-type cross-link structure 2, the first moving column 3, the second moving column 4, the fixing plate 21, the round rod 22, the limiting block 23, the first buckle 24, the second buckle 25, the third buckle 26, the hinge 8, the windproof rod 16, the first fixing block 19 and the second fixing block 17 are all made of 304 stainless steel or 6061 aluminum alloy profiles and plates, ensuring the overall corrosion resistance and structural strength. For projects that are more cost-sensitive, ordinary steel can also be used, but all surfaces must be hot-dip galvanized or sprayed with high-performance anti-corrosion paint. The plate body 7 is made of color steel plate with a surface coating, which takes into account economy, aesthetics and durability.

[0034] When using the device, the operator will push or transport the entire enclosure structure, which is fully folded and locked by the fixing plate 21 and the second buckle 25, to the target enclosure line at the construction site using the locking casters 5 and auxiliary casters 27 at its bottom. Then, the operator will forcefully pull the round rod 22 of the fixing plate 21 out of the second buckle 25 at the top of the second moving column 4, rotate the fixing plate 21 to the side of the first moving column 3, so that its round rod 22 is engaged in the first buckle 24 at the bottom of the first moving column 3, completing the storage in the working state. Then, the operator will step on the brake pedal of the locking caster 5 of the first moving column 3, face the enclosure structure, hold the second moving column 4 firmly with one or both hands, and pull it outward smoothly in the predetermined direction. Under the action of the pulling force, the internal scissor-type cross linkage structure 2 will start to work, driving all frames 1 to unfold synchronously and at equal intervals. At the same time, the frames 1 will be hooked onto the second moving column 3. All modular single enclosure panels 6 are driven, and each panel 7 rotates and unfolds synchronously around the hinge 8, ultimately forming a continuous, flat, rigid enclosure wall. After unfolding into place, immediately step on the brake pedal of the locking caster 5 at the bottom of the second moving column 4 to prevent the structure from sliding. Then, use a hammer to drive steel rods (or expansion bolts, for hardened ground) into the ground through the first fixing hole 20 on the first fixing block 19 at the bottom of each frame 1, and firmly fix the frame assembly to the ground. If the weather forecast indicates wind or the site has extremely high stability requirements, remove the windproof rod 16 from the third buckle 26 on the side of the frame 1, rotate the windproof rod 16 outward and downward so that it forms a 45-60 degree angle with the ground, and then use steel rods to fix the end of the windproof rod 16 to the ground through the second fixing hole 18 on the second fixing block 17 at its end, forming a diagonal brace, which greatly enhances the wind resistance. After construction is completed, first remove all the steel rods of the fixed frame 1 and windbreak rod 16; remove the windbreak rod 16 from the ground steel rods, rotate it upwards and lock it back into the third clip 26 on the side of the frame 1 for fixation; release the fixing plate 21 from the first clip 24 of the first moving column 3; release the brakes of all casters except the first moving column 3, and the operator, facing the enclosure structure, smoothly pushes the second moving column 4 in the direction of the first moving column 3. Under the thrust, the scissor-type cross linkage structure 2 moves in the opposite direction, driving all frames 1 to move in the same direction. As the structure folds towards the center, the modular single enclosure panel 6 also folds simultaneously. Once the structure is fully folded into a compact "accordion" shape, release the universal wheel brake of the first moving column 3, rotate the fixed plate 21 to directly above the second moving column 4, align the positions, and forcefully insert the two round rods 22 into the second buckle 25 at the top of the second moving column 4. At this time, the limiting block 23 at the end of the round rod 22 will be locked on the outside of the second buckle 25, achieving reliable locking. Finally, push or hoist the locked enclosure structure to the next construction site or warehouse. Panel replacement can be performed when the frame assembly is in any state of full deployment, partial deployment, or full folding. Locate the damaged single panel 6 that needs to be replaced, hold both ends of the single panel 6 with both hands, and lift it vertically upwards. Since it is only hung in the connecting slots 11 of the frame 1 through the connectors 10 at both ends, it can be easily removed as a whole. This process does not require any tools or loosening of adjacent parts. Take a new single panel 6 with good specifications, align the connectors 10 on both sides of it with the original position of the connecting slots 11 of the frame 1, and then insert it downwards until its bottom edge touches or approaches the first baffle 12 to be installed in place. The replacement work is completed instantly, and the function of the enclosure structure is immediately restored. If only a single panel 7 is damaged, only the single panel 7 needs to be replaced.

[0035] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0036] Finally, it should be noted that the above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
