Description

Technical Field

[0001] This utility model relates to the field of thermal insulation technology for factory buildings, and in particular to a structure for thermal insulation panels for factory exterior walls. Background Technology

[0002] In the construction and renovation of industrial plants, external wall insulation is a crucial step in ensuring stable internal temperatures and reducing energy consumption. Currently, common external wall insulation structures for industrial plants fall into two main categories: one is cast-in-place insulation, which involves applying insulating mortar or spraying insulating materials to the base layer of the exterior wall to form an insulation layer. While this type of structure can achieve overall insulation, it suffers from long construction cycles, high requirements for on-site working environments, and the need for complete removal and reconstruction during later repairs. Furthermore, the insulation material is prone to hollowing and cracking due to uneven pouring, leading to a decrease in insulation performance. The other type is prefabricated spliced ​​insulation panels, which achieve insulation by fixing prefabricated insulation panels to the base layer of the exterior wall. While this solves some of the problems associated with cast-in-place insulation, it still has many drawbacks.

[0003] Low installation efficiency: Existing prefabricated insulation panels mostly rely on bolt fixing. Each panel needs to be drilled and bolted in multiple positions on the top, bottom, left, and right. This not only increases the construction process but also requires repeated calibration of the bolt positions, resulting in long installation time. In addition, some insulation panels are quite heavy and require the assistance of large hoisting equipment for installation, which further reduces construction efficiency.

[0004] Poor protective performance: The bolt connection parts of most prefabricated insulation boards are directly exposed to the outside. In rainy or snowy weather, rainwater can easily seep into the bolt grooves, causing the bolts to rust. This not only affects the stability of the connection, but also requires the bolts to be replaced regularly, increasing maintenance costs. At the same time, the insulation materials of some insulation boards (such as rock wool and glass wool) are prone to moisture due to poor sealing, resulting in a significant reduction in insulation performance.

[0005] Insufficient flexibility in disassembly and assembly: Most existing prefabricated insulation panels are fixedly connected. When the factory needs to be partially renovated or the insulation panel is partially damaged, multiple surrounding panels need to be removed to replace the target panel. This is difficult to disassemble and assemble and can easily damage other panels, increasing the cost of renovation and maintenance.

[0006] To address the shortcomings of the existing technologies, there is a need for a factory exterior wall insulation board structure that is easy to install, provides good protection, offers stable thermal insulation, and is flexible in assembly and disassembly, in order to meet the requirements of efficient construction, long-term stable thermal insulation, and low-cost maintenance for industrial plants. Utility Model Content

[0007] To address the technical problems existing in the background art, this utility model proposes a factory exterior wall insulation board structure.

[0008] This utility model proposes a factory exterior wall insulation board structure, which is formed by splicing and assembling multiple boards. Each set of boards includes a vertically arranged base plate, a horizontally extending upper beam strip fixedly installed on the inner side wall of the top of the base plate, a horizontally extending lower bottom plate fixedly installed on the inner side wall of the bottom of the base plate, and side plates on both sides of the base plate. The upper beam strip, the lower bottom plate, and the two sets of side plates together enclose a closed cavity, which is filled with asbestos fibers. The outer side wall of the base plate is detachably connected to a front guard plate arranged parallel to the base plate through multiple sets of rib connectors. The multiple sets of rib connectors are distributed at intervals along the height and length directions of the base plate, and adjacent sets of rib connectors, the outer side wall of the base plate, and the inner side wall of the front guard plate together enclose multiple independent buffer cavities. The top of the upper beam has a groove along its length, and the front sidewall of the upper beam has a bolt groove along its length. The bottom of the lower base plate has a protrusion that extends vertically along its length. When two adjacent sets of plates are spliced, the protrusion on the lower base plate of the upper plate engages with the groove on the upper beam of the lower plate. Preferably, the bottom of the front guard plate extends downward along its length to form a baffle. When two adjacent sets of plates are spliced, the baffle at the bottom of the front guard plate of the upper plate covers the bolt groove on the front sidewall of the upper beam of the lower plate. Preferably, the connecting member between the front guard plate and the topmost plate rib of the base plate is inclined downward, and a gap is left between the bottom of the baffle and the topmost plate rib connecting member. Preferably, multiple sets of positioning pins are fixedly installed in the enclosed cavity. The multiple sets of positioning pins are arranged perpendicular to the base plate, and the multiple sets of positioning pins are distributed in a rectangular array along the height and length of the base plate. Preferably, each set of plates has a side plate on one side with a protruding locking strip along its height direction, and a side plate on the other side with a locking groove adapted to the locking strip along its height direction. When two horizontally adjacent sets of plates are spliced ​​together, the locking strip of one set of plates engages with the locking groove of the other set of plates.

[0009] Preferably, the rib connector is a metal plate, and both ends of the rib connector are fixed to the outer wall of the base plate and the inner wall of the front guard plate by welding or bolting, respectively, and the thickness of the rib connector is 3-8mm.

[0010] Preferably, the positioning pin is a metal pin, and the two ends of the positioning pin are fixedly connected to the upper beam strip and the lower base plate respectively, and multiple sets of the positioning pins are evenly spaced along the length direction of the upper beam strip.

[0011] The factory exterior wall insulation board structure proposed in this utility model has the following beneficial effects:

[0012] The modular panel design makes each panel lightweight, eliminates the need for heavy bolted connectors, and reduces material usage due to the buffer cavity. It can be handled and installed manually without the need for large hoisting equipment.

[0013] The upper and lower panels are positioned by interlocking with protrusions and grooves, while the left and right panels are positioned by interlocking with clips and slots. Only a small number of bolts are needed at the bolt slots for auxiliary fixing, and each panel only needs 2-3 bolts for fixing. Compared with existing technologies, this reduces the number of bolts used, greatly simplifies the installation process, shortens the installation time of a single panel, and improves the overall construction efficiency.

[0014] The baffle at the bottom of the front guard plate can completely cover the bolt groove, preventing rainwater from directly washing the bolts, preventing bolt corrosion, extending bolt service life, and reducing maintenance frequency;

[0015] The sealed cavity completely encapsulates asbestos fibers, and the positioning pins ensure that the fibers are tightly packed and not easily affected by moisture. This reduces the rate of decay of the thermal insulation performance of the asbestos fibers and ensures long-term stable thermal insulation.

[0016] The buffer cavity can absorb external impacts, such as wind loads or minor collisions, to prevent direct damage to the substrate and insulation layer, thus improving the impact resistance of the board.

[0017] It offers high flexibility in disassembly and assembly, low maintenance costs, and primarily uses snap-fit ​​connections between panels with bolts as a secondary method. During disassembly, only a few bolts need to be removed to separate the panels without damaging the surrounding panels. When replacing or modifying parts, the disassembly and assembly time of a single panel is shortened, and maintenance efficiency is improved.

[0018] The front guard plate and the base plate are connected by a detachable rib connector, allowing for the replacement of damaged front guard plate or base plate individually without replacing the entire plate, thus reducing maintenance costs.

[0019] The asbestos fiber filling is tight and completely sealed, and the thermal conductivity is stably maintained at 0.035-0.04W / (m・K), which improves the thermal insulation performance by more than 30% compared with the existing unsealed insulation board (thermal conductivity 0.05-0.06W / (m・K)).

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols 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 utility model, and should not be construed as limiting this utility model.

[0027] like Figures 1-4 The illustrated factory exterior wall insulation panel structure is formed by splicing together multiple panels, as shown in the following details:

[0028] Basic structure of the board: Each board includes a vertically arranged base plate 1, with a horizontally extending upper beam strip 2 fixedly installed on the inner side wall of the top of the base plate 1, and a horizontally extending lower base plate 3 fixedly installed on the inner side wall of the bottom. Side plates 101 are provided on both sides of the base plate 1. The upper beam strip 2, the lower base plate 3, and the two sets of side plates 101 enclose a closed cavity, which is filled with asbestos fiber. Asbestos fiber has excellent thermal insulation performance and corrosion resistance, making it suitable for long-term outdoor use. Multiple sets of positioning pins 102 are fixedly installed in the closed cavity. The positioning pins 102 are metal pins, with both ends fixedly connected to the upper beam strip 2 and the lower base plate 3, and are evenly spaced along the length of the upper beam strip 2. The positioning pins 102 are used to ensure that the asbestos fiber blocks are tightly filled, to prevent fiber displacement or loosening, and to completely cover the asbestos to prevent moisture absorption.

[0029] The front guard plate 4 and the rib connector 401 structure: The outer wall of the base plate 1 is detachably connected to the front guard plate 4, which is parallel to the base plate 1, through multiple sets of rib connectors 401; the multiple sets of rib connectors 401 are distributed at intervals along the height and length directions of the base plate 1, and two adjacent sets of rib connectors 401, the outer wall of the base plate 1 and the inner wall of the front guard plate 4 form multiple independent buffer cavities. The buffer cavities can absorb external impacts, such as wind and minor collisions, and protect the base plate 1 and the internal insulation layer; the rib connector 401 is a metal plate with a thickness of 3-8mm. This thickness range can ensure the connection strength and control the overall weight of the plate. The two ends are fixed to the outer wall of the base plate 1 and the inner wall of the front guard plate 4 by welding or bolting respectively. The detachable design makes it easy to replace the front guard plate 4 or the base plate 1 separately in the future.

[0030] Panel splicing structure:

[0031] Upper and lower splicing: The top of the upper beam strip 2 has a groove along the length direction, and the bottom of the lower base plate 3 has a protrusion 301 vertically protruding along the length direction. When the upper and lower adjacent plates are spliced, the protrusion 301 of the lower base plate 3 of the upper plate and the groove 201 of the upper beam strip 2 of the lower plate are movably engaged to achieve the initial positioning of the upper and lower plates. The bottom of the front guard plate 4 extends downward along the length direction to form a baffle 402. When the upper and lower plates are spliced, the baffle 402 of the front guard plate 4 of the upper plate covers the bolt groove 202 of the front side wall of the upper beam strip 2 of the lower plate. The bolt groove 202 is used to provide bolt installation space, so that the bolts can be directly nailed to the outer wall of the factory building to assist in fixing the plate. The plate rib connector 401 connecting the front guard plate 4 and the topmost plate rib connector 1 is set in a downward inclined state, and there is a gap between the bottom of the baffle 402 and the plate rib connector 401. The gap is used to guide rainwater to flow downward and prevent water from seeping into the bolt groove 202 or the closed cavity.

[0032] Left and right splicing: A retaining strip is protruding from one side plate 101 of each group of panels along the height direction, and a retaining groove adapted to the retaining strip is opened on the other side plate 101 along the height direction; when horizontally adjacent panels are spliced, the retaining strip of one group of panels engages with the retaining groove of another group of panels to achieve horizontal positioning.

[0033] In this embodiment, during operation:

[0034] On-site installation

[0035] Base treatment: Clean the base of the factory exterior wall to ensure that the base is flat (flatness error ≤3mm / m), and remove surface dust, oil and other impurities;

[0036] Bottom panel installation: Place the first row of panels (bottom panels) on the bottom baseline of the factory building exterior wall. After adjusting the position, drive M8×50mm expansion bolts into the bolt slots 202 of the upper beam strip 2 (two bolts are set for each panel, located at 1 / 3 of both ends of the upper beam strip 2) to fix it to the base layer.

[0037] Horizontal splicing: Insert the clips of adjacent panels into the slots of the installed panels to ensure a tight fit without gaps, and then fix the bolts through the bolt slot 202;

[0038] Vertical splicing: Align the protrusion 301 of the bottom plate 3 of the upper plate with the groove 201 of the upper beam strip 2 of the lower plate, slowly lower it so that the protrusion 301 is inserted into the groove 201. After adjusting the position, fix the bolt through the bolt groove 202 of the upper beam strip 2 of the upper plate. At this time, the baffle 402 of the upper plate automatically covers the bolt groove 202 of the lower plate.

[0039] Overall inspection: After installation, check whether the joints of the panels are tight, whether the bolts are secure, and whether the baffle 402 covers the bolt groove 202 to ensure that there is no looseness or omission.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
