Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an engineering panel structure. Background Technology

[0002] Plastic engineering panels are plastic sheets used in the engineering field, generally for assembling boxes or houses to form spaces that can accommodate people or objects. Currently, most engineering panels used for constructing modular walls in houses have both inside and outside corners, located on opposite sides of the panel, resulting in structural differences on both sides. Therefore, during construction, it is very easy for panels to be reversed, leading to improper splicing. Frequent flipping of the panels is necessary to ensure accurate alignment and splicing, increasing the workload and reducing efficiency. Furthermore, the splicing of panels using the inside and outside corners is limited by their structure, resulting in insufficient contact area and loosening at the joints, leading to insufficient structural stability of the modular walls. Utility Model Content

[0003] Therefore, it is necessary to address the above-mentioned shortcomings by providing an engineering panel structure that eliminates the need to flip the panels during construction, reduces the amount of construction work, increases work efficiency, and ensures strong panel splicing.

[0004] An engineering panel structure includes at least two first panels joined sequentially. Each first panel includes a first plate body and a second plate body arranged in parallel opposite directions. A casting area for casting filler is formed between the first plate body and the second plate body. Multiple support plates are arranged in parallel at intervals within the casting area. The two ends of each support plate are fixedly connected to the first plate body and the second plate body, respectively, and the two ends of each support plate are perpendicular to the surface of the first plate body and the surface of the second plate body, respectively.

The side of the horizontal support part adjacent to the horizontal part is provided with a second connecting part corresponding to the first connecting part. The inner surface of the fourth plate is provided with a plurality of third reinforcing ribs spaced parallel to each other. The area enclosed by the fourth plate and the support frame is used for pouring filler.

[0008] In one embodiment, the engineering plate structure further includes a fourth plate for connecting three first plates arranged in a triangular pattern. The fourth plate includes a fifth and a sixth plate arranged in parallel opposite directions, a seventh plate perpendicularly connecting the fifth and sixth plates and extending from the fifth plate towards the side opposite to the sixth plate, and an eighth plate opposite to the seventh plate. The eighth plate is perpendicularly connected to the fifth and sixth plates and extends from the fifth plate towards the side opposite to the sixth plate. The inner side of the fifth plate facing away from the seventh plate is provided with the first connecting portion, and the inner side of the other end of the fifth plate is provided with the second connecting portion. The inner side of the sixth plate facing away from the seventh plate is provided with the second connecting portion, and the inner side of the other end of the sixth plate is provided with the first connecting portion. The inner side of the seventh plate facing away from the fifth plate is provided with the second connecting portion, and the inner side of the eighth plate facing away from the fifth plate is provided with the first connecting portion. The inner sides of the fifth plate and the sixth plate are provided with a plurality of fourth reinforcing ribs spaced parallel to each other. The area enclosed by the fifth, sixth, seventh, and eighth plates is used for casting filler.

[0009] In one embodiment, the first connecting portion protrudes from the first end or the fourth end, and a notch is formed between the first connecting portion and the end face of the first end or between the first connecting portion and the end face of the fourth end. The second end or the third end has a pressing block adjacent to the second connecting portion and overlapping the notch. The height of the pressing block is adapted to the height of the notch, and the width of the pressing block is adapted to the width of the notch.

[0010] In one embodiment, the first connecting part has a guide notch that communicates with the slot and has a trumpet-shaped cross-section. The width of the guide notch gradually decreases along the direction close to the slot. The second connecting part has a guide limiting part near the plug. The outer contour shape of the guide limiting part is adapted to the inner contour shape of the guide notch.

[0011] In one embodiment, the transition portion between the guide notch and the slot opening forms a locking step within the slot, the angle between the locking step and the slot opening is less than or equal to 90°, and the connection portion between the connector and the guide limiting portion is provided with a hook portion that can be embedded between the locking step and the slot opening.

A first snapping area for snapping onto one first panel is formed between the partition plate and the vertical connector, and a second snapping area for snapping onto another first panel is formed between the transverse connector and the fixing plate.

[0014] The engineering panel structure of this utility model features a first connecting part and a second connecting part on both sides of a first panel, with the two first connecting parts on both sides of the first panel diagonally positioned, and the two second connecting parts on both sides of the first panel diagonally positioned as well. This creates a centrally symmetrical structure for the entire first panel. Thus, during panel splicing, it is not necessary to distinguish the left and right directions of the first panel before joining two panels, reducing the amount of splicing work and improving the efficiency of panel splicing. Furthermore, by creating a groove with an arc-shaped structure on the first connecting part and a connector with a corresponding shape on the second connecting part, the mating area between the first and second connecting parts is increased. The groove with the arc-shaped structure forms a locking mechanism with the connector, improving the firmness of the panel splicing and thus enhancing the structural stability of the building's composite walls.

[0028] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0029] Example 1

[0030] Please combine Figure 1-5This utility model discloses an engineering panel structure that eliminates the need for flipping panels during construction, reduces construction workload, increases work efficiency, and ensures strong panel splicing. The entire structure is made of PVC profiles, but other plastic materials with good mechanical strength, lightweight, and low cost can also be used. The engineering panel structure includes at least two first panels 100 sequentially spliced ​​together. When multiple first panels 100 are directly spliced, adjacent first panels 100 are arranged side-by-side so that all first panels 100 together form a single plane. Each first panel 100 includes a first plate body 110 and a second plate body 120 arranged parallel to each other. A pouring area for pouring filler is formed between the first plate body 110 and the second plate body 120. The filler can be cement or other building materials. Multiple support plates 130 are arranged parallel to each other within the pouring area. The two ends of each support plate 130 are fixedly connected to the first plate 110 and the second plate 120, respectively, and are perpendicular to the surfaces of the first plate 110 and the second plate 120. By placing the support plates 130 between the first and second plates 110, the first plate 100 is formed into a hollow structure. This reduces the weight of the first plate 100 while maintaining its overall thickness, thus reducing the difficulty of storage and transportation. Furthermore, the support plates 130 ensure the overall structural strength of the first plate 100 to meet its mechanical strength requirements. The multiple support plates 130 divide the pouring area into multiple spaced sub-spaces 140, each of which is used for pouring filling material. The first plate 110 includes a first end 111 and a second end 112 away from the first end 111. The second plate 120 includes a third end 121 on the same side as the first end 111 and a fourth end 122 on the same side as the second end 112. The inner side of the first end 111 and the inner side of the fourth end 122 are both provided with a first connecting portion 150. The inner side of the second end 112 and the inner side of the third end 121 are both provided with a second connecting portion 160. The inner surfaces of the first end 111 and the second end 112 refer to the side of the first plate 110 located within the casting area, and the inner surfaces of the third end 121 and the fourth end 122 refer to the side of the second plate 120 located within the casting area. The first end 111 and the second end 112 refer to the two ends of the cross-section of the first plate 110, not the top and bottom of the overall structure of the first plate 110. That is, the first end 111 and the second end 112 are located on the left and right sides of the first plate 110. Similarly, the third end 121 and the fourth end 122 refer to the two ends of the cross-section of the second plate 120, not the top and bottom of the overall structure of the second plate 120. That is, the third end 121 and the fourth end 122 are located on the left and right sides of the second plate 120. The term "end" as used hereafter is defined based on the cross-section of the plate, which is different from the top and bottom of the plate.It can be understood that in this embodiment, the first plate 100 actually has a centrally symmetrical structure. The left and right sides of the first plate 100 are centrally symmetrically arranged with respect to the middle of the casting area. In this way, during the construction process, it is not necessary to distinguish between the left and right sides of the first plate 100 to splice two adjacent first plates 100, which reduces the splicing difficulty of the first plate 100.

[0031] Furthermore, in this embodiment, the first connecting part 150 is provided with a groove 151 of an arc-shaped structure, and the end of the second connecting part 160 is provided with a connector 161. The outer contour shape of the connector 161 is adapted to the inner contour shape of the groove 151, and the connector 161 is inserted into the groove 151 on the adjacent first plate 100. For example, when splicing two side-by-side first plates 100 (including plate 1 and plate 2), the connector 161 on the first plate body 110 of plate 1 is inserted into the groove 151 of the first plate body 110 of plate 2, and the connector 161 of the second plate body 120 of plate 2 is inserted into the groove 151 of the second plate body 120 of plate 1; or the connector 161 on the first plate body 110 of plate 1 is inserted into the groove 151 of the second plate body 120 of plate 2, and the connector 161 of the first plate body 110 of plate 2 is inserted into the groove 151 of the second plate body 120 of plate 1. In addition, the slot 151 is designed with a superior arc structure (central angle greater than 180°). This superior arc structure locks the connector 161 in place, preventing the connector 161 from coming out of the slot 151 and improving the firmness of the first plate 100 splicing. In this embodiment, the first plate 110, the second plate 120, and the support plate 130 have the same height, their tops are on the same plane, and their bottoms are on the same plane. The first connecting part 150 and the second connecting part 160 have the same height and are positioned opposite each other. The height of the first connecting part 150 is less than or equal to the height of the first plate 110. When the height of the first connecting part 150 is less than the height of the first plate 110, the first connecting part 150 and the second connecting part 160 can be located at the top or bottom of the first plate 110, or they can be located in the middle of the first plate 110.

[0032] In one embodiment, the first plate 100 can be integrally molded by injection molding. Further, a plurality of first reinforcing ribs 113 are provided parallel to each other on the inner surfaces of both the first plate 110 and the second plate 120. The length of the first reinforcing ribs 113 is the same as the length of the first plate 110 and the second plate 120. On the one hand, they improve the mechanical strength of the first plate 110 and the second plate 120, preventing them from breaking under pressure. On the other hand, the first reinforcing ribs 113 also increase the friction between the filler in the casting area and the inner walls of the first plate 110 and the second plate 120, thus preventing the filler from moving within the casting area. In this embodiment, the cross-section of the first reinforcing rib 113 can be a semi-circular arc structure or a wavy structure; other protruding structures are also possible, which will not be elaborated here. The support plate 130 is provided with through holes 131 for connecting adjacent subspaces 140. By providing through holes 131 on the support plate 130, the filling materials in each subspace 140 can be connected as one, which improves the stability of the overall structure after the engineering plate structure is poured. On the other hand, the through holes 131 are also used to provide pipeline access channels so that pipelines can be arranged in the engineering plate structure.

[0033] In addition, in this embodiment, the outer surface of the first plate 110 (the side of the first plate 110 facing away from the casting area) and the outer surface of the second plate 120 (the side of the second plate 120 facing away from the casting area) are smooth and burr-free, and various patterns can be painted on them to increase their aesthetic appeal. In actual production, a first connecting part 150 and a second connecting part 160 can also be provided on the upper and lower sides (top and bottom) of the first plate 110 and the second plate 120. For example, a first connecting part 150 can be provided on the inner side of the top of the first plate 110, a second connecting part 160 can be provided on the inner side of the bottom of the first plate 110, a second connecting part 160 can be provided on the inner side of the top of the second plate 120, and a first connecting part 150 can be provided on the inner side of the bottom of the second plate 120 to increase the height of the engineering plate structure.

[0034] In one embodiment, the first connecting portion 150 protrudes from the first end 111 or the fourth end 122, and a notch 152 is formed between the first connecting portion 150 and the end face of the first end 111 or between the first connecting portion 150 and the end face of the fourth end 122. The second end 112 or the third end 121 has a pressing block 162 adjacent to the second connecting portion 160 and overlapping the notch 152. The height of the pressing block 162 is adapted to the height of the notch 152, and the width of the pressing block 162 is adapted to the width of the notch 152. In this way, when two adjacent first panels 100 are spliced, the gap at the splicing part is small, and the flatness of the joint formed after splicing is high, which can reduce the impact on the appearance of the wall surface of the house assembled with engineering panel structure.

[0035] Furthermore, the first connecting portion 150 has a guide notch 153 with a flared cross-section that communicates with the slot 151. The width of the guide notch 153 gradually decreases towards the slot 151. The second connecting portion 160 has a guide limiting portion 163 near the connector 161. The outer contour of the guide limiting portion 163 is adapted to the inner contour of the guide notch 153. By providing the flared guide notch 153 on the first connecting portion 150, the difficulty of inserting the connector 161 into the slot 151 is reduced, thereby reducing the difficulty of assembling the first plate 100. In addition, by providing the guide limiting portion 163 on the second connecting portion 160 with a shape adapted to the guide notch 153, the guide limiting portion 163 and the inner surface of the guide notch 153 can fit together after the first connecting portion 150 and the second connecting portion 160 are engaged, thereby reducing the gap at the connection point. Furthermore, the transition portion between the guide notch 153 and the slot 151 forms a locking step 154 ​​within the slot 151. The angle between the locking step 154 ​​and the slot 151 is less than or equal to 90°. The connection portion between the connector 161 and the guide limiting portion 163 is provided with a hook portion 164 that can be embedded between the locking step 154 ​​and the slot 151. By providing the locking step 154 ​​on the first connecting portion 150 and the hook portion 164 on the second connecting portion 160, the constraint force of the first connecting portion 150 on the second connecting portion 160 is further increased to prevent the second connecting portion 160 from falling off the first connecting portion 150, thereby improving the firmness and stability of the splicing of adjacent first plates 100.

[0036] Furthermore, in this embodiment, a convex arc-shaped transition portion 155 is formed between the edge of the notch 152 and the guide notch 153, and a concave arc-shaped transition portion 165 that fits with the convex arc-shaped transition portion 155 is formed between the pressure block 162 and the guide limiting portion 163. Thus, when the connector 161 of the second connecting portion 160 is inserted into the slot 151 of the first connecting portion 150, the side of the second connecting portion 160 adjacent to the splice seam of the first plate 100 is fully fitted with the first connecting portion 150. The gap at the joint is extremely small, preventing external water from entering the mating area between the first connecting portion 150 and the second connecting portion 160 through the splice seam of the first plate 100. This prevents mold growth at the splice seam of the engineering plate structure or damage to the plate due to long-term water accumulation, thereby extending the service life of the engineering plate structure.

[0037] Example 2

[0038] Please combine Figure 3-7In this embodiment, the engineering plate structure, based on the first plate 100, also includes a second plate 200 for closing the ends of the first plate 100. The second plate 200 includes a third plate body with a C-shaped cross-section. A first connecting portion 150 is provided on the inner surface of one end of the third plate body, and a second connecting portion 160 is provided on the inner surface of the other end of the third plate body. A plurality of second reinforcing ribs 210 are provided parallel to each other on the inner surface of the third plate body. The third plate body is used for casting filler. The structures of the first connecting portion 150 and the second connecting portion 160 in this embodiment are the same as those in Embodiment 1. For details, please refer to the description of the structures of the first connecting portion 150 and the second connecting portion 160 in Embodiment 1; further details will not be repeated here.

[0039] In this embodiment, the third plate includes two parallel and oppositely arranged horizontal plates 220, and a vertical plate 230 located between the two horizontal plates 220 and fixedly connected to the same side end of the two horizontal plates 220. The vertical plate 230 is perpendicular to the horizontal plates 220. The vertical plate 230 and the two horizontal plates 220 are integrally formed by injection molding. The entire third plate is made of PVC profile. A first connecting part 150 is provided on the inner side of one horizontal plate 220 away from the end of the vertical plate 230 (the side of the horizontal plate 220 located in the space where the filling material is poured). A second connecting portion 160 is provided on the inner side of a horizontal plate 220 away from the vertical plate 230. The height of the horizontal plate 220 is the same as the height of the vertical plate 230. The first connecting portion 150 and the second connecting portion 160 are at the same height and are positioned opposite each other. The height of the first connecting portion 150 is less than or equal to the height of the horizontal plate 220. When the height of the first connecting portion 150 is less than the height of the horizontal plate 220, the first connecting portion 150 and the second connecting portion 160 can be located at the top or bottom of the horizontal plate 220, or in the middle of the horizontal plate 220. A second reinforcing rib 210 is used to improve the strength of the third plate and increase the friction between the filling material and the inner wall of the third plate to prevent the filling material from moving within the third plate. The cross-section of the second reinforcing rib 210 can be a semi-circular arc structure, a wavy structure, or other protruding structures.

[0040] By setting the second plate 200, the ends (side ends) of the first plate 100 can be sealed, preventing the filler from flowing out or falling out of the pouring area of ​​the first plate 100 when it is poured. This also protects the side ends of the first plate 100 and improves their aesthetics. Furthermore, by providing the first connecting portion 150 and the second connecting portion 160 on the second plate 200, the gap between the first plate 100 and the second plate 200 after splicing is smaller, and the splicing structure is more stable. This reduces the impact on the appearance of the engineering panel structure and prevents mold and damage to the panels caused by water entering the joint.

[0041] Example 3

[0042] Please combine Figure 3-5 as well as Figure 8-9 In this embodiment, the engineering plate structure, based on the first plate 100, further includes a third plate 300 for connecting two vertically arranged first plates 100. The third plate 300 includes a fourth plate body with an L-shaped cross-section and a support frame located within the area enclosed by the fourth plate body and fixedly connected to the fourth plate body. The fourth plate body includes a horizontal portion 310 and a vertical portion 320 that are vertically and fixedly connected. The support frame includes a horizontal support portion 330 that is parallel to the horizontal portion 310 and fixedly connected to the vertical portion 320, and a vertical support portion 340 that is parallel to the vertical portion 320 and fixedly connected to the horizontal portion 310. The vertical support portion 340 and the horizontal support portion 330... The fourth plate is arranged in a cross configuration. A second connecting portion 160 is provided on the inner side of the end of the horizontal portion 310 (the side of the horizontal portion 310 adjacent to the horizontal support portion 330). A first connecting portion 150 is provided on the inner side of the end of the vertical portion 320 (the side of the vertical portion 320 adjacent to the vertical support portion 340). A first connecting portion 150 corresponding to the second connecting portion 160 is provided on the side of the horizontal support portion 330 adjacent to the horizontal portion 310. A second connecting portion 160 corresponding to the first connecting portion 150 is provided on the side of the vertical support portion 340 adjacent to the vertical portion 320. A plurality of third reinforcing ribs 350 are provided parallel to each other on the inner surface of the fourth plate. The area enclosed by the fourth plate and the support frame is used for pouring filler. The structure of the first connecting portion 150 and the second connecting portion 160 in this embodiment is the same as that in Embodiment 1. For details, please refer to the description of the structure of the first connecting portion 150 and the second connecting portion 160 in Embodiment 1; it will not be repeated here.

[0043] In this embodiment, both the horizontal support portion 330 and the vertical support portion 340 are provided with through holes 131. These through holes 131 are used to connect the area enclosed by the fourth plate and the support frame with the subspace 140 of the first plate 100, so that the filling material in the first plate 100 is connected to the filling material in the third plate 300 as a whole, and facilitates the installation of pipelines. The fourth plate and the support frame are integrally formed by injection molding, and the third plate 300 is made entirely of PVC profile. The height of the fourth plate is the same as the height of the support frame. The first connecting portion 150 and the second connecting portion 160 are at the same height and are positioned opposite each other. The height of the first connecting portion 150 is less than or equal to the height of the fourth plate. When the height of the first connecting portion 150 is less than the height of the fourth plate, the first connecting portion 150 and the second connecting portion 160 can be located at the top or bottom of the fourth plate, or at the top or bottom of the support frame, or in the middle of the fourth plate and the support frame. The third reinforcing rib 350 is used to enhance the strength of the fourth plate and increase the friction between the filler and the inner wall of the fourth plate to prevent the filler from moving within the fourth plate. The cross-section of the third reinforcing rib 350 can be a semi-circular arc structure, a wavy structure, or other protruding structures.

[0044] By setting a third plate 300, the connection between two first plates 100 that are vertically set at the corner can be realized. By setting a first connecting part 150 and a second connecting part 160 on the third plate 300, after the first plate 100 and the third plate 300 are spliced, the gap at the splicing part of the first plate 100 and the third plate 300 is small, and the splicing part is structurally stable. This can reduce the impact on the appearance of the engineering plate structure and avoid the problem of mold damage to the plate caused by water entering the splice.

[0046] Please combine Figure 3-5 as well as Figure 10-11In this embodiment, the engineering plate structure, in addition to the first plate 100, also includes a fourth plate 400 for connecting the three first plates 100 arranged in a triangular pattern. The fourth plate 400 includes a fifth plate 410 and a sixth plate 420 arranged in parallel opposite directions, a seventh plate 430 perpendicularly connected to the fifth plate 410 and the sixth plate 420 and extending from the fifth plate 410 to the side opposite to the sixth plate 420, and an eighth plate 440 opposite to the seventh plate 430. The eighth plate 440 is perpendicularly connected to the fifth plate 410 and the sixth plate 420 and extends from the fifth plate 410 to the side opposite to the sixth plate 420. A first connecting portion 150 is provided on the inner side of the fifth plate 410 at the end opposite to the seventh plate 430 (the side of the fifth plate 410 adjacent to the sixth plate 420), and the inner side of the other end of the fifth plate 410... A second connecting portion 160 is provided; the inner side of the sixth plate 420 facing away from the seventh plate 430 (the side of the sixth plate 420 adjacent to the fifth plate 410) is provided with the second connecting portion 160, and the inner side of the other end of the sixth plate 420 is provided with the first connecting portion 150; the inner side of the seventh plate 430 facing away from the fifth plate 410 (the side of the seventh plate 430 adjacent to the eighth plate 440) is provided with the second connecting portion 160, and the inner side of the eighth plate 440 facing away from the fifth plate 410 (the side of the eighth plate 440 adjacent to the seventh plate 430) is provided with the first connecting portion 150; a plurality of fourth reinforcing ribs 450 are provided parallel and spaced on the inner side of the fifth plate 410 and the inner side of the sixth plate 420; the area enclosed by the fifth plate 410, the sixth plate 420, the seventh plate 430 and the eighth plate 440 is used for casting filling material. The structure of the first connecting part 150 and the second connecting part 160 in this embodiment is the same as that of the first connecting part 150 and the second connecting part 160 in Embodiment 1. For details, please refer to the description of the structure of the first connecting part 150 and the second connecting part 160 in Embodiment 1, which will not be repeated here.

[0047] Alternatively, the fourth plate 400 in this embodiment can be understood as being obtained by deforming the first plate 100, which includes two support plates 130. Specifically, the two support plates 130 within the first plate 100 extend outward to the same side, and a first connecting portion 150 is provided at one end of the support plate 130 extending out of the casting area, and a second connecting portion 160 is provided at one end of the other support plate 130 extending out of the casting area, thus obtaining the aforementioned fourth plate 400. In this embodiment, the seventh plate 430 and the eighth plate 440 also have through holes 131 located between the fifth plate 410 and the sixth plate 420. These through holes 131 are used to connect the casting filling area on the fourth plate 400 with the casting area of ​​the first plate 100, so that the two filling materials are connected as one unit and it is convenient to run pipelines. The fifth plate 410, the sixth plate 420, the seventh plate 430, and the eighth plate 440 are integrally formed by injection molding, and the fourth plate 400 is made entirely of PVC profiles. The fifth plate 410, sixth plate 420, seventh plate 430, and eighth plate 440 have the same height. The first connecting part 150 and the second connecting part 160 have the same height and are positioned opposite each other. The height of the first connecting part 150 is less than or equal to the height of the fourth plate 400. When the height of the first connecting part 150 is less than the height of the fourth plate 400, the first connecting part 150 is located at the top or bottom of the fourth plate 400, or it can be located in the middle area of ​​the fourth plate 400. The fourth reinforcing rib 450 is used to improve the strength of the fourth plate 400 and increase the friction between the filling material and the inner wall of the fourth plate 400 to prevent the filling material from moving within the fourth plate 400. The cross-section of the fourth reinforcing rib 450 can be a semi-circular arc structure, a wavy structure, or other protruding structures.

[0048] By setting a fourth panel 400, the three first panels 100 arranged in a triangular pattern can be connected. This allows for the partitioning or installation of columns within the building's interior space, which is composed of structural components made of engineered panels, when other first panels 100 are spliced ​​onto the first panel 100, thus meeting construction requirements. By setting a first connecting part 150 and a second connecting part 160 on the fourth panel 400, the gap between the first panel 100 and the fourth panel 400 after splicing is smaller, and the splicing structure is more stable. This reduces the impact on the appearance of the engineered panel structure and avoids mold and damage to the panels caused by water entering the joints.

[0049] Example 5

[0050] Please combine Figure 1-13In this embodiment, the engineering plate structure, based on the first plate 100, further includes an edge-binding connector 500 for snapping onto the side, top, or bottom of the first plate 100. The edge-binding connector 500 includes a connecting plate with an L-shaped cross-section and a baffle with an L-shaped cross-section fixedly connected to the connecting plate. The connecting plate includes a transverse connector 510 and a vertical connector 520 that is perpendicular to and fixedly connected to the transverse connector 510. The baffle includes a partition plate 530 that is parallel to the vertical connector 520 and fixedly connected to the transverse connector 510, and a fixing plate 540 that is parallel to the transverse connector 510 and fixedly connected to the side plate of the partition plate 530. A first snapping area 550 for snapping onto one first plate 100 is formed between the partition plate 530 and the vertical connector 520, and a second snapping area 560 for snapping onto another first plate 100 is formed between the transverse connector 510 and the fixing plate 540. The width of the first snap-fit ​​area 550 is the same as the width of the second snap-fit ​​area 560, both equal to the thickness of the first plate 100. This ensures that the first plate 100 is snapped into either the first snap-fit ​​area 550 or the second snap-fit ​​area 560, guaranteeing the stability of the entire engineering plate structure. Preferably, the width of the partition plate 530 is smaller than the width of the vertical connector 520, i.e., the width of the vertical connector 520 is greater than the thickness of the first plate 100. In this embodiment, the edge-sealing connector 500 is used to be disposed on the side, top, or bottom of the first plate 100 to connect two vertically arranged first plates 100. Thus, through the joint cooperation of the first plate 100, the second plate 200, the third plate 300, the fourth plate 400, and the edge-sealing connector 500, a box-type structure can be assembled to meet the user's usage or living needs.

[0051] The engineering panel structure of this utility model features a first connecting part 150 and a second connecting part 160 simultaneously provided on both sides of the first panel 100. The two first connecting parts 150 on both sides of the first panel 100 are diagonally positioned, as are the two second connecting parts 160 on both sides of the first panel 100, resulting in a centrally symmetrical structure for the entire first panel 100. This eliminates the need to distinguish the left and right directions of the first panel 100 during panel splicing, reducing the amount of splicing work and improving efficiency. Furthermore, by creating a curved groove 151 on the first connecting part 150 and a corresponding connector 161 on the second connecting part 160, the mating area between the first connecting part 150 and the second connecting part 160 is increased. The curved groove 151 also forms a locking mechanism with the connector 161, enhancing the strength of the panel splicing and thus improving the structural stability of the building's composite walls.
