Description

Technical Field

[0001] The present invention relates to the technical field of building electromechanical pipeline installation, and specifically to a building sewage pipe connection device and construction method based on BIM. Background Art

[0002] With the advancement and development of architectural design technology, buildings with complex shapes and structures are becoming increasingly common, with irregular and curved shapes abounding. The increasing breadth and sophistication of information technology within buildings has led to the intricacies of the electromechanical integration systems within these unusually shaped buildings. Traditional project management methods struggle to efficiently handle such complex electromechanical integration systems, resulting in low project quality and project efficiency, and a constant stream of information errors and omissions, which have become a major concern for the quality of electromechanical system construction. Consequently, BIM technology has been introduced into some construction projects. Through a three-dimensional collaborative platform and visual information transmission, it provides a sound technical platform and solution for achieving integrated design and construction.

[0003] Using BIM technology for comprehensive pipeline layout can quickly improve construction detail design and node design, allowing for pre-assembly based on construction drawings before construction begins. This allows for the identification and early resolution of intersectional issues encountered by various disciplines during construction. In BIM practice, we can divide the accuracy of each discipline within the entire BIM model to ensure the specifications, dimensional accuracy, and integrity of related information for electromechanical system equipment and pipeline components. Furthermore, for models of related disciplines outside the electromechanical system, we ensure that their dimensional accuracy meets collision requirements, ensuring that the models function effectively in electromechanical engineering construction. This comprehensive pipeline layout technology allows management and construction personnel involved in electromechanical engineering to stay abreast of drawing changes and achieve dynamic control during the construction process. This also makes the assembly of electromechanical system pipelines more convenient, accurate, rapid, and high-quality.

[0004] By applying BIM technology to the building's piping system, compared to traditional electromechanical pipeline assembly methods, it has the advantages of convenience, accuracy, and speed in design and construction guidance. However, in the actual sewage installation and construction process, when installing sewage connection pipes using existing conventional structural designs, it is first necessary to drill holes in the floor slab. In fact, drilling holes in the floor slab is very difficult and the construction efficiency is low. The concentricity of the drilling holes between the upper and lower layers is very high. Once the drilling position deviates, the water pipe cannot be accurately installed. In addition, the sealing between the sewage pipe and the floor slab is difficult to meet the requirements. When there is a gap between the sewage pipe and the floor slab, if the water pipe leaks, the gap between the water pipe and the building floor slab will leak.

[0005] After searching, the Chinese patent application number is: 202120245454.0, the application date is January 28, 2021, and the name of the invention is: A connection structure for sewage pipe installation. The connection structure of the application includes a sewage pipe, the number of which is two. The bottom of the sewage pipe is tightly fitted with a first fixing plate, and the top of the sewage pipe is tightly fitted with a second fixing plate. The center of the top of the first fixing plate is rotatably connected to a threaded rod through a bearing. The application can fix the sewage pipe by providing the first fixing plate and the second fixing plate. By providing the threaded rod, arc plate, sealing gasket, positioning ring and ring groove, the sealing effect of the pipe can be improved when the pipe is installed.

[0006] For another example, the Chinese patent application number is: 201920170659.X, the application date is January 19, 2019, and the name of the invention is: A sewage pipe connection and installation structure. The pipe installation structure of this application includes two adjacent sewage pipes and a connecting assembly for sealing the two adjacent sewage pipes. The connecting assembly includes a connecting piece and a connecting frame provided on the outer walls of the two sewage pipes. One side of the connecting frame and the connecting piece are hingedly connected by a rotating piece and the other side is connected by a fixing piece. The two sewage pipes are arranged side by side, and the connecting piece is attached to the outer walls of the two sewage pipes. The connecting frame is rotated by the rotating piece and attached to the outer walls of the two sewage pipes. Finally, the connecting frame and the connecting piece are connected by the fixing piece, so that the two sewage pipes can be quickly and conveniently connected tightly.

[0007] The sewage pipe connection structure designs in the above two applications have, to a certain extent, ensured the sealed connection between the two sewage pipes. However, when the technical solutions of the above two applications are used for the layout of sewage pipes in buildings with multi-story floors, it is difficult to ensure the concentricity of all sewage pipes after installation, and it is impossible to accurately locate and layout the installation of the entire building sewage pipe system.

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0059] It should be noted that, in the description of the present invention, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0060] At the same time, in the description of the present invention, unless otherwise clearly stipulated and limited, the terms "install", "set", "connect", "fix", "screw" and so on should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0061] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0062] When laying out sewage pipes in a building, they are generally laid out along the bathrooms, with the pipes arranged along the height of the building, thereby draining sewage from every household in the building. Since sewage pipes are in contact with open water for a long time, waterproofing the gap between the sewage pipes and the floor is extremely important. In the prior art, in order to install the sewage pipes, holes are drilled in the corresponding locations of the bathrooms, and the sewage pipes are passed through the holes, thereby achieving the installation of the sewage pipes and the floor slabs. To avoid water leakage between the sewage pipes and the floor slabs, waterproof tape is wrapped between the outer wall of the sewage pipes and the floor slabs, and waterproof glue is laid on the waterproof tape to achieve a seal between the sewage pipes and the floor slabs.

[0063] However, as the use time increases, the waterproof glue will age and crack, and leakage will still occur between the sewage pipe and the floor slab. At the same time, when drilling holes in the floor slab, the drilling efficiency is very low and a large amount of polluted dust will be generated. In addition, it is necessary to ensure that the holes on the upper and lower floors are concentric, which actually requires a high level of skill from the drilling construction workers. The actual drilling construction efficiency is often low, and once the hole deviation phenomenon occurs, the sewage pipe cannot be installed, and the drill hole needs to be repaired and sealed, which further makes the construction efficiency unable to be guaranteed and increases the construction cost.

[0064] To this end, the present invention provides a BIM-based building sewage pipe connection device. By optimizing the overall structure of the device, on the one hand, the pipe connection device is directly cast as a whole on the floor slab, and an enclosed pipe 300 is pre-arranged on the pipe connection device to install the sewage pipe 400. After installation, the sewage pipe 400 is not prone to leakage, and the installation of the sewage pipe 400 of the present invention does not require drilling on the floor slab 200, which effectively solves the disadvantages of drilling holes in the floor slab to install the sewage pipe in the prior art; on the other hand, the present invention arranges the installation method of the enclosed pipe 300. Specifically, the enclosed pipe 300 is installed by setting a vacant active area 110 on the surface of the mosaic plate 100, so that the enclosed pipe 300 located therein has a certain adjustable space, and then when the sewage pipe 400 is installed, the coaxiality of the sewage pipe 400 on the entire floor can be ensured, ensuring the reliability and convenience of the installation of the sewage pipe 400, and also improving the installation accuracy and efficiency of the sewage pipe 400, significantly reducing the construction cost.

[0065] The pipe connecting device of the present invention and the construction method of a building sewage pipe using the pipe connecting device of the present invention are described in detail below with reference to specific embodiments.

[0066] Example 1

[0067] like Figure 1-2 As shown in FIG, a BIM-based building sewage pipe connection device of this embodiment includes a mosaic plate 100, an enclosure pipe 300, and a sewage pipe 400, wherein the mosaic plate 100 is embedded in the floor slab 200 and is arranged parallel to the floor slab 200. Figure 8-9 As shown, a vacant movable area 110 is processed on the interlocking plate 100; the enclosing pipe 300 is arranged perpendicular to the surface of the interlocking plate 100 and is movably installed in the vacant movable area 110. A joint is provided on the enclosing pipe 300, and the joint is sealedly connected to the interlocking plate 100. The upper and lower ends of the enclosing pipe 300 extend out of the upper and lower surfaces of the floor slab 200. The middle part of the enclosing pipe 300 is for the sewage pipe 400 to pass through, and the two pipe ends extending to the upper and lower surfaces of the floor slab 200 are detachably and sealedly connected to the sewage pipe 400 by threaded connectors. During the actual construction of the building sewage pipe connection device of the present invention, a component model of the sewage pipe connection device is pre-established through BIM technology, and the specific model of the sewage pipe connection device on each floor is obtained based on the model, and prefabrication is carried out. During the actual prefabrication, each component of the building sewage pipe connection device on each floor is calibrated through BIM technology, which can effectively ensure the accurate installation of each component.

[0068] Specifically, in this embodiment, the interlocking plate 100 and the floor slab 200 are arranged in parallel. Since the floor slab 200 is actually in a horizontal state, the vacant activity area 110 is preferably circular. The vacant activity area 110 can provide the enclosed pipe 300 with a larger activity range. After the sewage pipe 400 passes through the vacant activity area 110, when the sewage pipe 400 is installed on the upper and lower floor slabs 200, the sewage pipe 400 passes through the vacant activity area 110, so that the enclosed pipe 300 can be located in the vacant activity area 110 and can move, thereby ensuring that the enclosed pipe 300 on the upper and lower floor slabs 200 is in a concentric state, and further ensuring that the sewage pipe 400 is located in a vertical state between the upper and lower floor slabs 200, and the sewage pipes 400 on the upper and lower layers are in a concentric state, thereby ensuring the smooth flow of the sewage pipe 400 and avoiding the sewage pipe 400 from bending and causing blockage.

[0069] As another implementation of this embodiment, a joint portion is provided to ensure a sealed connection between the joint surface of the enclosing tube 300 and the interlocking plate 100, thereby preventing water from seeping from the upper surface of the floor slab 200 to the lower surface of the floor slab 200. The joint portion is provided on the periphery of the enclosing tube 300 and is capable of being sealed with the interlocking plate 100, thereby ensuring a seal between the enclosing tube 300 and the floor slab 200, preventing water from entering the floor slab 200 from the enclosing tube 300, and also preventing water from entering the floor slab 200 from the floor slab 200 through the gaps between the enclosing tubes 300 to the lower portion of the floor slab 200.

[0070] For details, see Figure 3 、 Figure 5 and Figure 8 The joint portion includes a flange 310, which is provided on the outer wall of the enclosing tube 300 and is parallel to the upper surface of the interlocking plate 100. A first sealing ring 320 is provided at the edge of the vacant active area 110, and the flange 310 abuts against the first sealing ring 320.

[0071] In one embodiment, the first sealing ring 320 can be made of ceramic material, and a ceramic ring can also be set at the junction of the flange 310 and the first sealing ring 320. A ceramic area is set at the edge of the vacant active area 110. When the flange 310 and the first sealing ring 320 are squeezed, the seal between the outer wall of the enclosing tube 300 and the joint surface of the mosaic plate 100 is achieved, preventing water from seeping from the upper surface of the floor slab 200 to the lower surface of the floor slab 200.

[0072] In some embodiments, the first sealing ring 320 can also be made of polymer rubber material, and the first sealing ring 320 can be squeezed through the flange 310 on the enclosing tube 300 to ensure the seal between the outer wall of the enclosing tube 300 and the joint surface of the mosaic plate 100.

[0073] In some embodiments, the flange 310 and the enclosing tube 300 are integrally formed, and a circular arc transition is formed between the flange 310 and the enclosing tube 300 to avoid stress concentration at the junction of the flange 310 and the enclosing tube 300 and to prevent the flange 310 from breaking.

[0074] In some embodiments, during the design, the thickness of the interlocking plate 100 is smaller than the thickness of the floor slab 200. Therefore, when the interlocking plate 100 is embedded in the floor slab 200, grooves will appear on the upper and lower surfaces of the floor slab 200. Therefore, a clamping mechanism is provided at the grooves located above and below the interlocking plate 100, which can be used to clamp the flange 310 and the edge of the vacant active area 110 (that is, the surface of the interlocking plate 100). By adjusting the clamping force between the flange 310 and the interlocking plate 100, the sealing degree of the combination between the interlocking plate 100 and the enclosing tube 300 can be ensured, thereby preventing water from entering the floor slab 200, thereby preventing water from extending from the gap between the enclosing tube 300 and the floor slab 200 to the lower surface of the floor slab 200.

[0075] Specifically, refer to Figure 5 The clamping mechanism includes a first cover plate 500. In this embodiment, in order to ensure that the flange 310 can be squeezed onto the mosaic plate 100 to ensure the sealed installation between the enclosed tube 300 and the mosaic plate 100, at the same time, the groove on the upper plate surface of the floor 200 can also be filled. The first cover plate 500 is arranged above the flange 310 of the outer wall of the enclosed tube 300. The first cover plate 500 is provided with a first through hole 510 for the enclosed tube 300 to pass through. The first through hole 510 is circular, and the enclosed tube 300 can be moved in the first through hole 510, thereby adjusting the enclosed tube 300 between the upper and lower floor slabs 200 to maintain a concentric state. A compression screw 530 passes through and is threadedly connected to the first cover plate 500. The compression screw 530 is rotatably connected to the upper surface of the mosaic plate 100. By rotating the compression screw 530, the first cover plate 500 is driven to move toward the flange 310 of the outer wall of the enclosing tube 300, so that the flange 310 can be pressed against the first sealing ring 320, and then squeezed on the mosaic plate 100 to complete the sealing combination.

[0076] In some embodiments, to further ensure the reliability of the compression of the flange 310 on the enclosing tube 300 against the first sealing ring 320, thereby ensuring that the flange 310 is evenly squeezed on the interlocking plate 100, an elastic member 520 and a compression ring 521 are provided between the first cover plate 500 and the flange 310. The two sides of the elastic member 520 respectively abut against the first cover plate 500 and the compression ring 521, while the other side of the compression ring 521 abuts against the flange 310. By adjusting the compression screw 530 so that the compression screw 530 is vertical and the rod end is rotatably connected to the upper plate surface of the interlocking plate 100, the first cover plate 500 is driven downward, thereby compressing the elastic member 520 and the compression ring 521. The compression ring 521 elastically abuts against the flange 310, thereby ensuring elastic compression of the flange 310 and the first sealing ring 320, which is conducive to ensuring uniform compression of the first sealing ring 320. As the floor slab 200 vibrates or ages, the elastic extrusion state can ensure that the first sealing ring 320 is always in a sealed and snug state, thereby ensuring the seal between the enclosing tube 300 and the mosaic plate 100 .

[0077] At the same time, when the lower surface of the floor slab 200 needs to be filled, since the lower surface of the floor slab 200 is a non-water-receiving surface, a simple cover can be used for covering during actual construction.

[0078] like Figure 4 As shown, the enclosing tube 300 extending from the lower surface of the interlocking plate 100 is provided with a clamping flange 311, which engages with the outer wall of the clamping flange 311. A second sealing ring 330 is provided on the lower surface of the interlocking plate 100 at the edge of the vacant active area 110, with the clamping flange 311 abutting against the second sealing ring 330.

[0079] A second cover plate 600 is disposed below the lower surface of the interlocking plate 100. A second through-hole 610 is provided on the second cover plate 600. A clamping screw 620 is rotatably threadedly connected to the second cover plate 600. The clamping screw 620 is vertically disposed, and the upper end of the clamping screw 620 abuts against the clamping flange 311. Furthermore, to ensure a sealed connection between the enclosing tube 300 and the clamping flange 311, a clamping seal 340 is disposed between the outer wall of the enclosing tube 300 and the clamping flange 311.

[0080] In one embodiment, the second through hole 610 on the second cover plate 600 can allow the enclosed tube 300 to pass through, and the enclosed tube 300 can form a certain movable space in the second through hole 610. After the above-mentioned sewage pipe 400 is installed, the clamping screw 620 can be screwed to push the clamping flange 311 so that the clamping flange 311 moves along the length direction of the enclosed tube 300, and the clamping sealing ring 340 is tightened to ensure the sealing of the gap between the enclosed tube 300 and the clamping flange 311, and the clamping flange 311 is abutted against the second sealing ring 330, thereby ensuring the sealing between the clamping flange 311 and the mosaic plate 100.

[0081] Reference Figure 6 and Figure 7 In this embodiment, to ensure a tight connection between the upper end of the enclosed pipe 300 and the sewage pipe 400, a clamping mechanism is provided at the end of the enclosed pipe 300 extending to the upper surface of the floor slab 200 to clamp the inserted sewage pipe 400. Furthermore, a splice tube 372 is provided at the lower end of the sewage pipe 400. The outer diameter of the splice tube 372 is smaller than that of the sewage pipe 400, and the splice tube 372 is spliced ​​to the upper end of the next sewage pipe 400.

[0082] Specifically, the clamping mechanism includes a clamping pipe segment 350 and a threaded screw pipe 410. The clamping pipe segment 350 is provided at the pipe end of the enclosing pipe 300 extending out from the upper plate surface of the floor slab 200. The clamping pipe segments 350 are arranged in multiple intervals along the circumferential direction of the enclosing pipe 300. The pipe end of the enclosing pipe 300 is provided with a first flange 360. The sewage pipe 400 is provided with a threaded screw pipe 410. The threaded screw pipe 410 is threadedly connected to the outer wall of the sewage pipe 400, and the clamping pipe segment 350 is provided with a threaded section. The threaded screw pipe 410 cooperates with the threaded section on the clamping pipe segment 350 and the pipe end abuts against the first flange 360.

[0083] During the actual installation, after the first-floor floor 200 is hoisted, the sewage pipe 400 is installed in the enclosed pipe 300, and the threaded screwing pipe 410 on the sewage pipe 400 is rotated to screw the threaded screwing pipe 410 onto the threaded section on the clamping pipe segment 350 until it abuts against the first flange 360 ​​provided on the pipe end of the enclosed pipe 300, thereby ensuring a tight connection between the enclosed pipe 300 and the interlocking plate 100. After the installation of the first-floor sewage pipe 400 and floor slab 200 is completed, the second-floor floor slab 200 and other prefabricated parts are hoisted using hoisting equipment, so that the enclosed pipe 300 on the second-floor floor slab 200 is plugged into the upper end of the first sewage pipe 400, and the cycle is repeated until the entire prefabricated house is completely installed.

[0084] Example 2

[0085] Reference Figure 3-5 As shown, the building sewage pipe connection device of this embodiment has a main structure basically the same as that of Example 1, and the main difference between it and Example 1 is that the enclosed pipe 300 extending out of the pipe cavity of the lower plate surface of the floor slab 200 is provided with a built-in flange 370, and the lower pipe end of the sewage pipe 400 is close to the built-in flange 370, and a built-in sealing ring 371 is provided between the two.

[0086] The lower end of the sewage pipe 400 is provided with a splice 372, the outer diameter of which is smaller than that of the sewage pipe 400. The splice 372 passes through the built-in flange 370 and is inserted into the upper end of the adjacent sewage pipe 400 to achieve splice connection with the next sewage pipe 400.

[0087] Furthermore, a second flange 380 is provided at the lower end of the enclosing tube 300, and a fastening threaded cap 700 is provided at the upper end of the sewage pipe 400. The fastening threaded cap 700 is threadedly connected to the outer wall of the sewage pipe 400 and one end abuts against the second flange 380.

[0088] The upper floor 200 is hoisted onto the prefabricated wall of the lower floor, and the upper end of the sewage pipe 400 is passed through the lower end of the enclosing pipe 300. The threaded cap 700 is screwed and tightened so that one end of the threaded cap 700 abuts against the second flange 380, thereby ensuring the installation between the sewage pipe 400 and the enclosing pipe 300, and realizing the connection between the upper and lower sewage pipes 400, and ensuring the sealing between the upper and lower sewage pipes 400.

[0089] Example 3

[0090] The main structure of the building sewage pipe connection device of this embodiment is basically the same as that of embodiment 1. The main difference between this embodiment and embodiment 1 is that: in order to achieve coaxial installation of all sewage pipes 400 in the building, the vacant activity area 110 of this embodiment is circular as a whole, and a centering limit unit is provided on the inner wall thereof in contact with the enclosed pipe 300. The centering limit unit is used to center the enclosed pipe 300 inserted in the vacant activity area 110 to ensure the concentricity of the enclosed pipe 300 and the vacant activity area 110. When the sewage pipe 400 is not installed, The enclosed pipe 300 is located in the middle of the vacant activity area 110. When the sewage pipe 400 is installed, it can basically ensure that the sewage pipe 400 is in the center position and can be adjusted appropriately to ensure that the enclosed pipe 300 on the upper and lower floor slabs 200 is in a concentric position and adjusted along with the position adjustment of the upper and lower sewage pipes 400, thereby ensuring that the enclosed pipe 300 and the sewage pipe 400 on the upper and lower floor slabs 200 are in a concentric state to avoid the sewage pipe 400 from tilting or bending, and ensure that the sewage pipe 400 is conductive in a high-rise environment.

[0091] Specifically, such as Figure 8-9 As shown, the centering limiting unit includes a plurality of elastic limiting arms 120 spaced apart along the inner wall of the vacant active area 110. One end of each elastic limiting arm 120 is movably engaged with the inner wall of the vacant active area 110, and the other end of the elastic limiting arm 120 abuts against the outer wall of the enclosing tube 300. The elastic limiting arms 120 described in this embodiment are metal elastic sheets and are arranged in a spiral shape along the circumference of the vacant active area 110, thereby limiting the enclosing tube 300 and maintaining a concentric state with the vacant active area 110. At the same time, in order to facilitate the installation of the elastic limiting arm 120, a snap-in groove 110 is provided on the inner wall of the vacant active area 110, and one end of the elastic limiting arm 120 is snap-in set in the snap-in groove 110, and the elastic limiting arm 120 is generally in the shape of an arc plate and the extended end is set to be spherical. On the one hand, it can better fit on the wall of the enclosing tube 300, thereby realizing the centering effect of the activity of the enclosing tube 300.

[0092] Example 4

[0093] like Figure 6-9 As shown, this embodiment is a BIM-based building sewage pipe connection device. Its main structure is basically the same as that of Example 1. The main difference from Example 1 is that the mosaic plate 100 is a plate-shaped structure as a whole. In this embodiment, it is designed as a "D"-shaped structure. In actual production, it can be designed according to actual design requirements. It only needs that the mosaic plate 100 is a flat plate as a whole. For the convenience of description, this embodiment specifically describes the mosaic plate 100 with a "D"-shaped structure as an example:

[0094] like Figure 8-9 As shown, the arc-shaped outer wall edge of the interlocking plate 100 of this embodiment is processed with a plurality of interlocking notches 131 distributed at intervals; the provision of the plurality of interlocking notches 131 increases the contact area between the interlocking plate 100 and the concrete during subsequent pouring, so as to further enhance the tightness of the interlocking between the interlocking plate 100 and the floor slab 200 and prevent water from seeping into the floor slab 200.

[0095] In this embodiment, the interlocking plate 100 is further improved. In terms of material selection, the interlocking plate 100 is a polymer plastic plate, a rust-proof metal plate or a ceramic plate. It has sufficient toughness and a long service life, which can extend the actual service life. The interlocking plate 100 can be embedded in the floor slab 200, thereby ensuring the sealing effect between the joint surface of the floor slab 200 and the interlocking plate 100.

[0096] Furthermore, to further ensure the reliable engagement between the interlocking plate 100 and the floor slab 200 and prevent water from seeping into the floor slab 200, the outer wall edges of the interlocking plate 100 are symmetrically machined with interlocking flanges 130. Two sets of interlocking flanges 130 extend axially along the vacant active area 110. Each interlocking flange 130 has an L-shaped plate structure, and a plurality of interlocking teeth 132 are provided at intervals along the plate edges of the interlocking flange 130 parallel to the interlocking plate 100. The arrangement of the interlocking teeth 132 gives the two sets of interlocking flanges 130 a serrated shape, thereby ensuring a tight engagement between the two sets of interlocking flanges 130 and the concrete, preventing gaps between the two sets of interlocking flanges 130 and the floor slab 200, and thus preventing water from entering the gap between the floor slab 200 and the interlocking plate 100.
