Description

Technical Field

[0001] This invention relates to the field of building decoration technology, and in particular to an integrated connection system for indoor rammed earth columns. Background Technology

[0002] Rammed earth is an ancient building material, consisting of compacted, dense blocks of mud with few gaps, used for house construction. This technique has been used extensively in my country from the Neolithic Age until the 1950s and 60s. The basic method of rammed earth construction involves dry-laying and compacting layers of soil, a highly strenuous physical labor requiring thousands to tens of thousands of workers. Rammed earth walls were the earliest method used in my country for constructing city walls. They were built using templates filled with clay or limestone, and each layer was rammed with a pestle.

[0003] Modern rammed earth walls are divided into two types: solid rammed earth walls for construction and decorative rammed earth walls. Decorative rammed earth walls, like solid rammed earth walls, involve artistic creation based on formwork, filling, and compaction. To enhance the aesthetics of buildings, rammed earth structures are often used in the interiors of large hotels, banquet halls, and conference centers. However, due to the excessive weight of rammed earth walls, they are difficult to use solely as decorative structures indoors. Therefore, how to reduce the weight of rammed earth buildings while ensuring their structural stability is a pressing issue in the field of architectural decoration. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an integrated connection system for indoor rammed earth columns, which solves the problem that rammed earth structures made by the existing ramming process are difficult to use as decorative structures indoors.

[0005] To achieve the above and other related objectives, this invention provides an integrated connection system for indoor rammed earth columns, comprising a plurality of decorative rammed earth columns, a steel frame, and GRG ceiling panels. The decorative rammed earth columns are arranged in a ring indoors, with the tops of the columns connected to the top of the steel frame. Suspension channel steel is evenly installed around the lower part of the steel frame, and the GRG ceiling panels are mounted on the suspension channel steel via suspension rods. The ends of the steel frame, the suspension channel steel, and the GRG ceiling panels are connected by end plates. Each decorative rammed earth column includes a decorative main frame and a base. The decorative main frame, consisting of a panel, vertical reinforcing ribs, and a rammed earth layer, forms the main structure of the rammed earth column. Multiple angle brackets are arranged horizontally along the main frame. A base panel surrounds the exterior of the main frame, and a wire mesh surrounds the exterior of the base panel. The wire mesh is bolted to the main frame. The ends of the angle brackets penetrate the base panel and the wire mesh. Vertical reinforcing ribs penetrate vertically and are installed on the angle brackets. A rammed earth layer is arranged outside the wire mesh, with the vertical reinforcing ribs located within the rammed earth layer. A bonding layer is formed between the rammed earth layer and the wire mesh by applying mortar.

[0006] As a preferred technical solution, the sealing plate includes a flame-retardant base plate and a gypsum board, wherein the gypsum board is configured as a double layer, and the thickness of each layer of the gypsum board is 9.5 mm.

[0007] As a preferred technical solution, the main decorative frame includes supporting square steel, transverse square steel, longitudinal square steel, and connecting square steel. The bottom end of the supporting square steel is fixedly installed on the ground. The transverse square steel is arranged in multiple layers around the outside of the supporting square steel in the shape of rammed earth columns from the lower right to the top. The longitudinal square steel connects the transverse square steel between layers. The connecting square steel connects different spatial points in each layer of transverse square steel. The contact points of the supporting square steel, the transverse square steel, the longitudinal square steel, and the connecting square steel are all welded connections. The top layer of the supporting square steel extends out of the rammed earth layer. The steel frame is welded and installed on the top of the supporting square steel.

[0008] As a preferred technical solution, the plane of the transverse square steel is perpendicular to the supporting square steel, the longitudinal square steel is parallel to the supporting square steel, the connecting square steel is parallel to the supporting square steel, one side of the connecting square steel is in contact with the supporting square steel, and one side of a portion of the longitudinal square steel is in contact with the supporting square steel.

[0009] As a preferred technical solution, the transverse square steel includes a straight segment and an arc segment, the arc segment is connected to the supporting square steel through an L-shaped square steel, and the corner of the L-shaped square steel is located at the arc segment connection.

[0010] As a preferred technical solution, the vertical reinforcing ribs are staggered with the longitudinal square steel bars.

[0011] As a preferred technical solution, two supporting square steels are provided, and a reinforcing square steel is provided between the two supporting square steels, and the reinforcing square steel is welded to the supporting square steels.

[0012] As a preferred technical solution, the base panel includes a flame-retardant board and a calcium silicate board from the inside out.

[0013] As a preferred technical solution, a skirting board is provided on the outer periphery of the main decorative frame, forming a gap between the skirting board and the main decorative frame. The base panel and wire mesh are located within the gap, and the vertical reinforcing ribs and rammed earth layer are located on the upper part of the skirting board. The outer edge of the skirting board protrudes from the rammed earth layer.

[0014] As a preferred technical solution, the rammed earth layer is coated with a protective agent.

[0015] As described above, the integrated connection system for indoor rammed earth columns of the present invention has the following beneficial effects:

[0016] (1) The top of the decorative rammed earth column of the present invention is connected by a steel frame, and the GRG ceiling panel is installed on the steel frame, which not only ensures the stability of the overall connection of the decorative rammed earth column, but also enhances the overall aesthetics of the decorative design.

[0017] (2) The decorative rammed earth column of the present invention adopts a decorative support frame as the main support structure, and rammed earth is carried out on the outside of the main support structure to form a rammed earth column with a hollow internal structure. Without affecting the aesthetics of the rammed earth column, the overall weight of the rammed earth column is reduced, the production cost of the rammed earth column is reduced, and the application of rammed earth technology in the field of interior decoration is realized.

[0018] (3) By applying slurry between the rammed earth layer and the wire mesh, the present invention improves the adhesion between the rammed earth layer and the wire mesh, prevents the rammed earth layer from falling off the wire mesh, and ensures the stability of the overall structure of the rammed earth column.

[0019] (4) The present invention sets corner brackets on the main decorative frame. The corner brackets penetrate the base panel and the wire mesh. The corner brackets connect the vertical reinforcing bars, which are embedded in the rammed earth layer. This makes the various parts of the rammed earth column connected into a unified whole, avoiding the separation between the layers.

[0020] (5) The decorative support frame of the present invention is formed by welding supporting square steel, transverse square steel, longitudinal square steel and connecting square steel. The square steels restrict each other to ensure that the supporting steel frame will not deform. At the same time, the supporting steel frame is covered with flame-retardant board and calcium silicate board, so that the rammed earth column has flame-retardant properties while ensuring that the rammed earth material will not enter the interior of the decorative steel frame during the ramming process.

[0034] like Figures 7-10 As shown, this embodiment provides an integrated connection system for indoor rammed earth columns, including several decorative rammed earth columns (12 in this embodiment), a steel frame 111, and a GRG ceiling panel 114. The 12 decorative rammed earth columns are arranged in a ring indoors. The tops of the several indoor rammed earth columns pass through the top of the steel frame 111. The lower part of the steel frame 111 is evenly equipped with a hoisting channel steel 113 along the circumference of the steel frame 111. The GRG ceiling panel 114 is installed on the hoisting channel steel 113 through a hoisting rod 115. The ends of the steel frame 111, the hoisting channel steel 113, and the GRG ceiling panel 114 are connected by a sealing plate. The sealing plate includes a flame-retardant base board and a gypsum board. The gypsum board is double-layered, and the thickness of each layer of gypsum board is 9.5 mm.

[0035] Decorative rammed earth columns include a decorative main frame 1, a base panel, a wire mesh 5, vertical reinforcing bars 6, and a rammed earth layer 11. For example... Figures 1-2As shown, the decorative main frame 1 is used to form the main structure of the indoor rammed earth column. The decorative main frame 1 is connected to the ground by an embedded plate, which is fixed to the ground by chemical bolts. The size of the embedded plate is 350*350*10 mm, and the chemical bolts used are RM12 chemical bolts. At the same time, an embedded plate is set at the connection between the decorative main frame 1 and the wall. The embedded plate is fixed to the wall by chemical bolts. The size of the embedded plate at this location is 200*200*8 mm, and the chemical bolts used are RM12 chemical bolts. The embedded plates at the ground and the embedded plates at the wall must be secure after installation, and there should be no looseness or suspension. The main decorative frame 1 is constructed from welded square steel, including supporting square steel 11, transverse square steel 12, longitudinal square steel 13, and connecting square steel 14. In this embodiment, the supporting square steel 11 is made of 400*200*8mm hot-dip galvanized square tubing. The bottom end of the hot-dip galvanized square tubing is welded to an embedded plate on the ground. The verticality of the supporting square steel 11 is adjusted within the allowable error range, and the weld points are treated with rust prevention. The transverse square steel 12 is made of 50*50*5mm hot-dip galvanized square tubing, arranged in multiple layers from the lower right to the upper left outside the supporting square steel 11. The spacing between the layers of transverse square steel 12 is 600mm. The transverse square steel 12 forms a closed-loop structure, creating the shape of a rammed earth column, including straight and curved sections. Angle brackets 2 are pre-embedded on the transverse square steel 12 for easy later connection. The spacing between the angle brackets 2 is 400mm, and the size of the angle brackets 2 is 50*50*5mm. All weld points are treated with rust prevention. The longitudinal square steel 13 connects the transverse square steel 12 between layers. The longitudinal square steel 13 is made of 50*50*5mm hot-dip galvanized square tubing, and all weld points are treated with rust prevention. The connecting square steel 14 connects different spatial points in each layer of transverse square steel 12. The contact points of the supporting square steel 11, transverse square steel 12, longitudinal square steel 13, and connecting square steel 14 are all welded connections. The transverse square steel 12 includes straight segments and curved segments. The curved segments are connected to the supporting square steel 11 by L-shaped square steel 15, and the corners of the L-shaped square steel 15 are connected to the curved segments. The plane of the transverse square steel 12 is perpendicular to the supporting square steel 11, the longitudinal square steel 13 is parallel to the supporting square steel 11, and the connecting square steel 14 is parallel to the supporting square steel 11. One side of the connecting square steel 14 is attached to the supporting square steel 11, and one side of part of the longitudinal square steel 13 is attached to the supporting square steel 11. The top layer of the supporting square steel 11 extends out of the rammed earth layer 11, and the steel frame 111 is welded and installed on the top of the supporting square steel 11. In this embodiment, there are two supporting square steels 11, and a reinforcing square steel 112 is provided between the supporting square steels 11. The reinforcing square steel 112 is welded to the supporting square steel 11. The reinforcing square steel 112 is a hot-dip galvanized square tube with a specification of 200*400*8mm.

[0036] like Figure 3As shown, the main decorative frame 1 is surrounded by a base panel, and the base panel is surrounded by a wire mesh 5. The wire mesh 5 is fixedly connected to the transverse square steel 12 and the longitudinal square steel 13 by bolts. The end of the angle bracket 2 passes through the base panel and the wire mesh 5. The base panel can only be installed after the concealed acceptance of the main decorative frame 1 is qualified. The base panel includes a flame-retardant board 3 and a calcium silicate board 4. The flame-retardant board 3 is set inside the calcium silicate board 4. Due to the insufficient plasticity and nail-holding power of the calcium silicate board 4, the base uses a 15mm thick flame-retardant board 3. Flame-retardant board 3, with grooves and bends at the arc-shaped positions, is fixed to a 50*50*5mm hot-dip galvanized square tube using self-drilling screws. After the flame-retardant board 3 is fixed, its flatness is inspected. Once the inspection is passed, calcium silicate board 4 is laid on top of the flame-retardant board 3. At the arc-shaped positions, calcium silicate board 4 is cut into strips and tightly spliced ​​with automatic screws at intervals of 150-170mm. The corner bracket 2 can be installed by manually cutting the board material. Dust removal equipment should be used to remove dust during cutting. For ease of installation, the positions of corner bracket 2 can be marked on the base panel before drilling holes. Wire mesh 5 is covered with calcium silicate board 4 and fixed to the main frame with bolts. To increase the strength between the rammed earth and the calcium silicate board, a slurry treatment is required to form an adhesive layer 8. The adhesive layer 8 is made of a mixture of glue, cement, and mortar. Before slurrying, the calcium silicate board and wire mesh 5 are cleaned and the reinforcing bars are moistened with water. The premixed material is gradually and evenly applied to the wire mesh 5, with each application of slurry being uniform and moderate. Vertical reinforcing ribs 6 are welded onto corner bracket 2. The vertical reinforcing ribs 6 are made of hot-dip galvanized square tubes with a specification of 20*20*2. The vertical reinforcing ribs 6 are used to increase the reliability of the vertical reinforcing ribs 6. When welding the vertical reinforcing ribs 6, ensure that the verticality of each vertical reinforcing rib 6 is within the allowable error range. The weld joints are treated with rust prevention. The vertical reinforcing ribs 6 are staggered with the longitudinal square steel 13.

[0037] like Figure 4 As shown, a skirting board 7 is provided on the outside of the main frame 1, forming a gap between the skirting board 7 and the main frame 1. The base panel and wire mesh 5 are located in the gap. The vertical reinforcing ribs 6 and the rammed earth layer 11 are located on the upper part of the skirting board 7, and the outer edge of the skirting board 7 protrudes from the rammed earth layer 11.

[0038] like Figures 5-6As shown, to achieve the desired rammed earth effect, the casting mold 9 is supported by transparent plexiglass to control the layers, texture, and color of the rammed earth. During casting, the casting mold 9 is erected from bottom to top, with the bottom layer of casting mold 9 placed on the kick plate 7. The mold is adjusted vertically according to the site boundary line and fixed on the outside using L40 angle steel 10, with the spacing between angle steel 10 not exceeding 400mm. The materials used for the rammed earth layer 11 must be mixed on-site strictly according to the rammed earth material mix ratio. The amount of each raw material for each batch of rammed earth is determined according to the mix ratio, and the weighing standards for rammed earth powder and small stones are fixed separately. Each batch is weighed during loading. The loading sequence should be: first load the rammed earth powder, then the small stones, mix evenly, and then add an appropriate amount of water according to the viscosity requirements, using a mixer. The mixing time is determined based on the experimental results of the shortest rammed earth mixing time. Before feeding the material, clean the debris inside the casting mold 9 and the oil stains on the vertical reinforcing ribs 6, and check the positional relationship between the vertical reinforcing ribs 6 and the rammed soil layer 11. The casting mold 9 should be evenly coated with a release agent before feeding. The mixed rammed soil material can be transported on-site using wheelbarrows, buckets, etc. After mixing and unloading, it should be transported to the feeding location promptly, and the delay should not exceed the initial setting time of the rammed soil material. The rammed soil material should be poured into the mold using an iron shovel or a specially made small hopper. The rammed soil material should be poured into the mold in layers and compacted layer by layer, with each layer's thickness controlled between 80 and 150 mm. When tamping the rammed soil material, do not touch the vertical reinforcing ribs 6 and the corner brackets 2. During tamping, check the hammer's condition frequently to avoid bulging, hollow areas, etc. The hammer's movement interval should be less than 100 mm, and the duration of each hammer point should be until a layer of slurry appears on the surface. Pay attention to the wire mesh 5 during tamping. To prevent missed hammering, continuous tamping must be performed on both sides of the vertical reinforcing ribs 6. The rammed earth structure can be demolded 72 hours after setting. After demolding, promptly repair any holes left by the casting mold 9 on the rammed earth column according to the color and texture effect, and protect the finished product. The curing time for rammed earth columns is 14 days in summer and 28 days in winter. After the moisture content is less than 10%, apply the protective agent. General defects do not need to be repaired. For defects such as contamination or obvious grout leakage on the rammed earth wall surface, appropriate repairs should be made before applying the protective agent. The rammed earth wall protective agent should be diluted with water according to the appropriate ratio, stirred evenly, and applied by spraying or brushing. Two coats should be applied, with the second coat applied before the first coat is completely dry, and it must completely cover the surface without dripping or missing areas.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
