Description

Technical Field

[0001] The invention belongs to the technical field of interior decoration, in particular to a unitized partition wall assembly system on the ground of an indoor overhead floor of a building. Background Art

[0002] Indoor partition walls, as an important component of indoor enclosed space, mainly include structural partition walls, masonry partition walls, frameless prefabricated strip partition walls, light steel frame thin plate (paper-faced gypsum board, glass magnesium board, cement pressure board, calcium silicate board) partition walls, glass partition walls, etc.

[0003] For masonry partition walls, due to the requirements of earthquake resistance and construction technology, the partition wall involves multiple complicated processes such as planting reinforcement, masonry, binding of structural beams and columns, formwork, pouring and curing of concrete, surface plastering, and a large amount of wet work construction. The partition wall forming process is relatively cumbersome. In addition to the time-consuming process itself, the corresponding wet work curing must reach a certain strength and the moisture content must reach the corresponding natural aging period. Obviously, masonry partition walls have the following disadvantages:

[0004] ① It takes a long time, produces a lot of noise and waste, and is not conducive to green construction;

[0005] ②High labor intensity, low construction productivity and high labor costs;

[0006] ③ Construction quality and cost are difficult to control;

[0007] ④The construction progress is slow and the construction period is long.

[0008] Therefore, interior masonry partition walls are currently being gradually replaced by lightweight strip board partition walls and light steel frame thin plate partition walls.

[0009] According to the "Green Construction Code for Building Engineering" GB / T50905-2014 and the "Guiding Opinions on Vigorously Developing Prefabricated Buildings" issued in 2016, the main purpose is to advocate "energy saving, water saving, material saving and green environmental protection", "design standardization, factory production, construction assembly, decoration componentization", "encourage the development of new materials and new components for decoration", encourage the use of decoration components, reduce on-site work volume, solve the problems of long construction period, high energy consumption and noise caused by on-site manual processing, and so on. , dust pollution and other problems, and actively promotes building industrialization, modularization and green construction; in 2018, the "Technical Code for Interior Decoration Engineering of Building Industrialization" T / CECS558-2018 document was issued. Article 4.1.8 of the document requires: "Interior decoration projects should be designed using pipeline separation..." The so-called pipeline separation method is a method of separating equipment pipelines from building structures to meet the needs of not damaging the corresponding building structure, floor cushion, isolation layer, leveling layer, building waterproofing and other structural layers when they are dismantled, modified and replaced.

[0010] For interior floor and floor projects, while meeting the requirements of specialized pipeline laying and separation, indoor floors should be elevated. Therefore, the partition walls in this space are the walls above the elevated floor. For indoor lightweight stripboard partitions and light steel-framed thin-plate partitions, the keels, thin panels, strips, and decorative finishes are all completed on-site, following a sequential process. These still rely on on-site manual construction and lack the characteristics of industrialized, prefabricated construction, as well as the corresponding requirements of "standardized design, factory-based production, prefabricated construction, and componentized decoration." Therefore, the development of a partition wall prefabrication technology system is urgent and represents a cutting-edge technology yet to be developed in the construction industry.

[0011] The main factors restricting the assembly technology of unitized partition walls on the ground of indoor overhead floors are as follows:

[0012] 1. Lightweight partition walls often require a concrete base at the base of the wall to be installed and fixed, as well as for the rooting, wall-ground connection, and load-bearing requirements. This concrete base is often a traditional cast-in-place concrete base. The traditional cast-in-place concrete base construction process is a wet operation, which is cumbersome, labor-intensive, low in productivity, high in labor costs, difficult to control in terms of construction quality and cost, slow in progress, and long in construction period. This is an outdated traditional construction process. Currently, there is no mature, supporting prefabricated partition wall system base.

[0013] 2. How do partition walls take root on the elevated floor? How do partition walls connect to the elevated floor? These attributes in the architectural decoration industry are new forms, new methods, and new technologies. Previously, there was no such technical support, nor such standard drawings to refer to.

[0014] 3. For indoor prefabricated partition walls, in terms of their overall height, their upper and lower ends are basically "standing upright", and professional pipelines are laid inside the partition walls. When performing upper and lower hanging and plug-in assembly, there is basically no space. This limits the overall, one-way, upper and lower hanging and plug-in assembly of the partition wall components. The two sides of the partition wall can only be decomposed into two-way unit components and then assembled together. From a design perspective, regardless of the type of partition wall, as long as it meets its function, the wall thickness should not be too large to avoid occupying excess space. The thickness of the skeleton, which is decomposed into two-dimensional unit components on both sides, determines the thickness of the wall. If the skeleton thickness is not restricted, the wall thickness cannot be controlled. If the skeleton thickness is restricted, according to the material mechanics: ε (strain) = M (bending moment) / W (section resistance moment) × E (elastic modulus), it is known that when the material, elastic modulus E, and bending moment M are constant, the larger the section resistance moment W, the smaller the strain ε and the greater the stiffness. The section resistance moment W is proportional to the moment of inertia of the cross section, and for a rectangular cross section, the moment of inertia is proportional to the cube of the cross section height. Therefore, when the skeleton thickness (section height) and the wall thickness are reduced, the stiffness will inevitably be reduced. How to solve the problem of decomposing the two sides into a system composed of small-sized skeleton thickness units and the stiffness of the system; how to solve the problem of combining and assembling the indoor prefabricated partition wall in the form of separate unit components on the two sides; and how to solve the construction method of the unit components on these two sides. There was no such technology before and no precedent to refer to. This technology is both difficult and key.

[0015] 4. Because the specialized pipelines laid within the partition walls and the specialized pipelines laid on the floor are considered in an integrated and systematic manner, this limits the layout of the specialized pipelines in the partition walls and floors, the way and method of interface integration, and the assembly process. There are also structural connections in the length, height, and thickness directions of the partition walls. How to solve these problems is unprecedented and there is no current standard atlas. Many technical issues are both difficult and key.

[0016] 5. For prefabricated partition walls composed of light steel keels, the thin wall thickness and low rigidity of the light steel keels lead to uncontrollable deformation of the prefabricated partition wall components during transportation and installation, and the quality control problem is difficult. Ultimately, the industrialized assembly method is sacrificed and the traditional processes such as on-site manual construction, installation, and painting are returned, which deviates from the purpose of relevant regulations on assembly and industrialization.

[0017] 6. For prefabricated partition walls composed of relatively rigid steel keels, although the rigidity and deformation problems are solved, the sound bridge phenomenon is correspondingly increased due to the increased rigidity, which reduces the sound insulation of the partition wall system and adds new problems. How to solve this problem is a certain challenge.

[0018] 7. How to connect, connect and soundproof the prefabricated partition walls at the inner and outer corners? Currently, there is no such ready-made, matching and mature systematic technology.

[0019] 8. The interface, structure and sound insulation issues between the decorative panel components of prefabricated partition walls are the key links in partition wall technology. Currently, there are no mature, relevant supporting technologies and ready-made standard drawings. Summary of the Invention

[0052] The structure of the present invention and the technical effects to be achieved will be described below with reference to specific embodiments and accompanying drawings. However, the selected embodiments are only for illustration and explanation and are not intended to limit the scope of the present invention.

[0053] like Figure 1 As shown, the present invention provides a unitized partition wall assembly system on the ground of an indoor elevated floor of a building, comprising an elevated floor structure 1, a plurality of base structures 2, a keel structure 3 and a partition wall structure 4.

[0054] The elevated floor structure 1 includes an elevated floor 12 disposed above a building floor 11 . The elevated floor 12 and the building floor 11 are fixedly connected via a plurality of elevated brackets 13 , forming an installation space 14 between the elevated floor 12 and the building floor 11 .

[0055] like Figure 1A 、 Figure 3 、 Figure 3A 、 Figure 4 As shown, the base structure 2 includes two symmetrically arranged GRC bases 21, which are located in the installation space 14. There is a gap between the two GRC bases 21 to form a pipeline space 22. Specifically, a supporting angle steel 23 is provided on the side of the GRC base 21, and the top surface of the supporting angle steel 23 is against the edge of the bottom surface of the raised floor 12. An L-shaped wire pipe 24 is provided in the pipeline space 22. The top of the wire pipe 24 is located above the installation space 14, and the bottom is passed through the corresponding GRC base 21. The cross-section of the GRC base 21 is L-shaped, so that the cross-section of the two GRC bases 21 is T-shaped as a whole. A Halfen groove 25 with an upward opening is provided at the bottom of the pipeline space 22. The bottom surface of the Halfen groove 25 is fixedly connected to the building floor 11 by an anchor bolt 15. A number of vertical T-bolts 26 are provided in the Halfen groove 25. The T-bolt 26 has a vertical positioning screw 261, and the bottom end of the positioning screw 261 has a T-shaped cross-section end 262, which is located in the halfn groove 25. The positioning screw 261 passes through the opening of the halfn groove 25, and the top end is located above the installation space 14. The positioning screw 261 is provided with a limit nut 263 near the end 262. Preferably, in order to facilitate the connection and positioning of the adjacent base structures 2, as shown in FIG. Figure 3AAs shown, each GRC base 21 has a stepped positioning protrusion 211 at its end, and a sealing strip 212 can be provided on the contact surface of adjacent positioning protrusions 211. In addition, a sealing strip 213 can also be provided between the bottom of the GRC base 21 and the building floor 11.

[0056] For sealing and noise reduction, such as Figure 3 As shown, the location where the conduit 24 meets the GRC base 21 is covered with a silicone sealant 27 having a T-shaped cross-section. Both the top and bottom ends of the conduit 24 are provided with ferrule-type pipe connectors for quick connection to the bottom end of the linear pipe within the partition wall structure 4 and the horizontal pipe within the installation space 14.

[0057] The GRC base 21 of the present invention is a prefabricated component that replaces traditional wet-work construction methods involving cast-in-place concrete, which are labor-intensive, have low construction productivity, high labor costs, slow construction progress, and long construction periods. The base structure 2 integrates the interface technology of pre-embedded, standardized, and pre-fitted ferrule-type pipe joints for the integrated and standardized pipelines in the partition walls and floors. Corresponding anchor bolts and conduits are laid through the gap formed by the combined GRC base 21 on the left and right halves. This conduit interface is an integrated, standardized interface for the pipelines in the partition walls and floors. At both ends of this interface, both the horizontal pipelines in the installation space 14 and the vertical pipelines in the partition wall structure 4 can be conveniently connected to the pre-embedded ferrule-type pipe joints. This is also one of the important features of the two-piece, separated, combined base structure of the present invention.

[0058] The keel structure 3 includes a ground keel 31 and a top keel 32, both of which have the same structure and are arranged opposite to each other.

The two first support portions 313 are located on the top surfaces of the two GRC bases 21, respectively. The wire conduit 24 and the positioning screw 261 are inserted through holes in the top plate 311, and the end of the positioning screw 261 is fitted with a positioning nut 264. The top purlin 32 comprises a rectangular base plate 321, with L-shaped second side plates 322 connected on either side. The outer ends of each second side plate 322 are connected to a second support portion 323, also with a rectangular cross-section. Each second support portion 323 is connected to a second gusset portion 324, also with a rectangular cross-section. The second gusset portion 324 extends downwardly and is provided with a second gusset slot 325. The two second support portions 323 are located on the bottom surface of the I-beam 5 at the top of the building. The bottom surface of the I-beam 5 is provided with a plurality of vertical fixing screws 51, which pass through holes in the base plate 321 and are fitted with fixing nuts 52 at their bottom ends. To improve sealing performance, the bottom surface of the first support portion 313 and the top surface of the second support portion 323 are provided with a plurality of first sealing strips 33, and the side surfaces of the first side plate 312 and the second side plate 322 are provided with a plurality of second sealing strips 34.

[0059] like Figure 2 、 Figure 2AAs shown, the partition wall structure 4 is located between the floor purlins 31 and the ceiling purlins 32. The partition wall structure 4 includes a first decorative panel 41 and a second decorative panel 42, both of which are parallel to each other. The first decorative panel 41 and the second decorative panel 42 are both rectangular. Specifically, the first decorative panel 41 and the second decorative panel 42 are honeycomb aluminum decorative panels, stone honeycomb composite panels, wood decorative panels, or painted glass. Alternatively, the first decorative panel 41 and the second decorative panel 42 are coated with fluorocarbon paint or wallpaper on the outside. The back of the first decorative panel 41 is provided with a plurality of first vertical purlins 411, and adjacent first vertical purlins 411 are connected by a plurality of first transverse purlins 412. The back of the second decorative panel 42 is provided with a plurality of second vertical purlins 421, and adjacent second vertical purlins 421 are connected by a plurality of second transverse purlins 422. The first horizontal keel 412 and the second horizontal keel 422 at the top are respectively located on both sides of the second side plate 322 of the top keel 32, and the first horizontal keel 412 and the second horizontal keel 422 at the bottom are respectively located on both sides of the first side plate 312 of the ground keel 31. Between the first vertical keels 411 and the second vertical keels 421 on both sides, a first mounting plate 43 with an L-shaped cross section is fixedly installed on the inner side of the first vertical keel 411, and a rectangular second mounting plate 44 is fixedly installed on the inner side of the second vertical keel 421. A clamp 45 is provided on the side of the first mounting plate 43 facing the second mounting plate 44, and a clamp 46 corresponding to the clamp 45 is provided on the side of the second mounting plate 44. Figure 1C 、 Figure 2A As shown, the clamp 46 and the chuck 45 of the present invention are existing double-wheel ball-bumping clips. Specifically, the cross-section of the chuck 45 is T-shaped, and the middle part has a clip part 451 with a diamond-shaped cross-section. The clamp 46 has a shell 461, and the side of the shell 461 is provided with two clamping parts 462 that can rotate relative to each other. There is a clamping space with a diamond-shaped cross-section between the two clamping parts 462, and a roller 463 is provided at the end of each of the two clamping parts 462.

[0060] Furthermore, the first gusset plate slot 315 and the second gusset plate slot 325 are provided with gusset plates 35 to cover and fix the bottom and top of the first decorative plate 41 and the second decorative plate 42 .

[0061] like Figure 2AAs shown, to facilitate the connection, positioning, and sealing of adjacent partition wall structures 4, the first and second vertical purlins 411, 421 on one side of the partition wall structure 4 extend outwardly and are provided with a first sealing portion 47 with a rectangular cross-section. The first and second vertical purlins 411, 421 on the other side of the partition wall structure 4 also extend outwardly and are provided with a second sealing portion 48 with a rectangular cross-section. The second sealing portion 48 is located outside the partition wall structure 4 and can extend into the adjacent partition wall structure 4 to overlap with the corresponding first sealing portion 47. The first sealing portion 47 is closely attached to the backside of the first and second trim panels 41, 42, with a gap between the second sealing portion 48 and the first and second trim panels 41, 42. The first and second sealing portions 47, 48 have rectangular cross-sections. The first and second vertical purlins 411, 421 on either side of the partition wall structure 4 also have rectangular cross-sections, and the cross-sections of the first and second sealing portions 47, 48 are smaller than those of the first and second vertical purlins 411, 421. A sealing strip 49 is provided between the stacked first sealing portion 47 and the second sealing portion 48. The sealing strip 49 can be a self-adhesive strip. Figure 2B As shown, a strip groove 491 may also be provided on the opposite surfaces of the first sealing portion 47 and the second sealing portion 48 , and the end of the sealing strip 49 may be installed in the strip groove 491 .

[0062] The present invention uses aluminum alloy ground and top keels to isolate and stretch the keels of the partition wall structures 4 on both sides to a certain distance, so that the overall thickness of the partition wall is met, and the decorative panels on both sides are combined into a partition wall structure through double-wheel bead buckles, which not only solves the sound bridge problem when the two are connected, but also solves the stiffness problem of the small skeleton thickness unit parts on both sides. Because it uses double-wheel bead buckles to connect and lock the thinner skeletons on both sides of the partition wall structure into a "system combined simply supported beam load-bearing structure", its reaction mode and structural form are changed to form a linkage, overall resistance, and combined resistance structure, and the stiffness of the partition wall structure is correspondingly strengthened.

[0063] like Figure 7 As shown, the present invention also provides a connection between the partition wall structure 4 and the external corner wall 6. The structure of the external corner wall 6 is identical to that of the partition wall structure 4. The external corner wall 6 and the partition wall structure 4 are perpendicularly connected to form a external corner. A external corner keel 61 is provided at the junction. This external corner keel 61 has an L-shaped cross-section and features ridges 62 at each end, extending into the interior of the external corner wall 6 and the interior of the partition wall structure 4. The top and bottom of each ridge 62 are fixedly connected to the top keel 32 and the floor keel 31, respectively, via angle brackets. A external corner sealing strip 63 is provided between each ridge 62 and the corresponding first and second vertical keels 411, 421.

[0064] like Figure 8As shown, the present invention also provides a connection between a partition wall structure 4 and an internal corner wall 7. The ends of the partition wall structure 4 are located at the vertical joints between the two internal corner walls 7, forming a T-shaped cross-section between the two internal corner walls 7 and the partition wall structure 4, thus forming an internal corner. The internal corner wall 7 has the same structure as the partition wall structure 4. The second vertical purlin at the end of each internal corner wall 7 adjacent to the partition wall structure 4 is a internal corner purlin 70. In addition to the first sealing portion 47 and second sealing portion 48, which are identical to the second vertical purlins of the partition wall structure 4, the internal corner purlin 70 also has a third sealing portion 71 extending into the interior of the partition wall structure 4.

[0065] The characteristics and advantages of the unitized partition wall assembly system for the indoor elevated floor of the building of the present invention are as follows:

[0066] 1. The base structure of the present invention greatly improves the industrialization level and construction efficiency of the partition wall base, reduces labor intensity, and in this case, due to the implementation of factory-based and componentized processing and production, the corresponding quality is guaranteed.

[0067] 2. The present invention takes "deconstruction + reconstruction" as the path, and develops and manufactures factory-produced left and right side combined partition wall structures. It uses left and right unitized components for separation technology, forming its own system to reduce the effect of the same skeleton sound bridge on sound wave conduction and assembly problems. Through the aluminum alloy gusset plates along the ground and top keels and several groups of double-wheel bumper buckles arranged on the first and second vertical keels, the left and right side decorative panels are assembled and reconstructed by point and line contact, thereby reducing the sound bridge effect. Its structure and assembly principle are similar to those of the unitized curtain wall.

[0068] 3. The present invention has developed and manufactured the interface and construction technology between partition wall structures. Through the arrangement of tongue and groove, combined first sealing part, second sealing part and sealing strip, the first vertical purlins and second vertical purlins of adjacent partition wall structures are connected to form the same plane. At this time, the adjacent vertical purlins of the partition wall structure on the same side are tightly connected, and the first horizontal purlins and second horizontal purlins at the upper and lower ends and the sealing strips on the ground and top purlins at the corresponding positions are also tightly connected and sealed to form an integrated structure.

[0069] 4. This invention has developed a technology for the intersection and construction of partition wall structures with planes that are T-shaped (for internal corners) and L-shaped (for external corners). This technology can not only meet the sealing function of the partition wall panels at the corners on the same side, but also ensure the reliable connection of the partition wall panels on both sides. It considers and solves related intersection and construction problems from multiple dimensions and in a comprehensive and systematic manner.

[0070] 5. The present invention adopts sealed aluminum alloy floor and roof keels, and two and four grooves are set on the three outer sides respectively (the bottom surface and top surface of the floor and roof keels) for embedding silicone rubber sealing strips to achieve the sealing effect with the top surface of the GRC base, building floor and partition wall structure; the top plate of the floor keel is provided with elliptical through-holes with alternating widths of 17mm and 23mm for bolts and pipelines, which also serve as adapters for fixing the GRC base top.

[0071] The present invention is defined by the claims, but those skilled in the art may make various obvious changes or modifications based on the claims, all of which are within the spirit and scope of the present invention.
