Description

Technical Field

[0001] The present invention relates to the technical field of building decoration, and in particular to an integrated construction process for indoor rammed earth columns and GRG top surfaces. Background Art

[0002] Rammed earth is an ancient building material. It consists of compacted, dense, and seamless mud blocks, used in house construction. This technique has a long history in my country, from the Neolithic Age until the 1950s and 1960s. Rammed earth is a highly laborious process involving layers of earth compacted by dry-piling. This process involves numerous workers, ranging from thousands to tens of thousands. Rammed earth walls, the earliest method of city wall construction in my country, are constructed using formwork filled with clay or limestone, compacted layer by layer with pestles.

[0003] Modern rammed earth walls are divided into two categories: solid architectural rammed earth walls and decorative rammed earth walls. Like solid rammed earth walls, decorative rammed earth walls are artistically created using a process of formwork, filling, and compaction. To enhance the aesthetics of the building, large hotels, banquet halls, and conference centers often incorporate rammed earth structures. However, due to the sheer weight of rammed earth walls, their use as mere decorative structures is difficult. Reducing the weight of rammed earth structures while maintaining their structural stability is a pressing challenge in the field of architectural decoration. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an integrated construction process for indoor rammed earth columns and GRG top surfaces, which is used to solve the problem that the building structures manufactured by the solid ramming process in the prior art are difficult to be used for interior decoration.

[0005] To achieve the above and other related purposes, the present invention provides an integrated construction process for indoor rammed earth columns and GRG top surfaces, comprising the following steps:

[0006] Step 1: manufacture rammed earth columns on site, which are arranged in a circular shape indoors;

[0007] Step 2: Connect the tops of the rammed earth columns through a steel frame, which is arranged in a ring shape;

[0008] Step 3: Install the lifting channel steel evenly along the lower end surface of the steel frame;

[0009] Step 4: Install the GRG ceiling molding board on the hoisting channel steel through the hanging rod;

[0010] Step 5: Seal and connect the ends of the steel frame, hoisting channel steel, and GRG ceiling molding panels through sealing plates.

[0011] As a preferred technical solution, the step 1 includes the following steps:

[0012] S1. Install the main decorative frame. Set an embedded plate at the connection between the main decorative frame and the ground. Fix the embedded plate to the ground with chemical bolts. Weld the bottom of the main decorative frame to the embedded plate.

[0013] S2. Weld the corner brackets at the corresponding points of the main decorative frame;

[0014] S3. Set up a base panel on the periphery of the main decorative frame. First, drill holes in the base panel at positions corresponding to the corner brackets, and fix the base panel to the main decorative frame with self-drilling screws.

[0015] S4. Lay a steel mesh on the outside of the base panel, pass the ends of the angle brackets through the steel mesh, set vertical reinforcement ribs on the outside of the steel mesh, weld the vertical reinforcement ribs to the angle brackets, and slurry the steel mesh to form a bonding layer;

[0016] S5. Arrange the skirting around the main decorative frame, support the casting mold on the skirting, fix the casting mold to the base panel with bolts, form a casting cavity between the casting mold and the base panel, and apply a release agent on the inner wall of the casting cavity;

[0017] S6. Rammed earth materials are placed in layers into the mold and compacted layer by layer to form a rammed earth layer. After compaction and solidification, the casting mold is removed;

[0018] S7, moving the casting mold to the upper end of the solidified rammed earth structure, with the lower end of the casting mold fitting against the outer side of the rammed earth structure, and the upper part being fixed to the flame retardant plate with bolts;

[0019] S8. Repeat S6 and S7 until pouring is completed.

[0020] As a preferred technical solution, the step S8 further includes:

[0021] S9. Maintain the rammed earth columns and repair any defects, contamination, or leakage.

[0022] S10. Apply protective agent to the outer surface of the rammed earth column.

[0023] As a preferred technical solution, in step S6, the rammed earth material is prepared by first adding rammed earth powder and then adding small stones, stirring evenly, adding water according to the viscosity, and stirring with a mixer.

[0024] As a preferred technical solution, in step S7, after the casting mold is removed, the holes left by the fixed casting mold on the rammed earth structure are repaired according to the color and texture effects.

[0025] As a preferred technical solution, in step S9, the curing time of the rammed earth columns is 14 days in summer and 28 days in winter.

[0026] As a preferred technical solution, in step S10, the protective agent is applied by spraying or brushing, and is applied twice, with the second application being performed before the first application is completely dry.

[0027] As a preferred technical solution, in step S1, 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 from the lower right to the top in the shape of rammed earth columns around the outside of the supporting square steel. 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.

[0028] As a preferred technical solution, after the pouring of step S8 is completed, the top of the decorative main frame extends out of the rammed earth layer, and the steel frame is welded to the top of the decorative main frame.

[0029] As a preferred technical solution, in step five, the sealing board includes a flame-retardant base board and a gypsum board, and the gypsum board is arranged as a double layer, and the thickness of each layer of the gypsum board is 9.5 mm.

[0030] As described above, the integrated construction process of indoor rammed earth columns and GRG top surfaces of the present invention has the following beneficial effects:

[0031] (1) The tops of the decorative rammed earth columns produced by the present invention are connected through a steel frame, and the GRG ceiling molding panels are installed on the steel frame, which not only ensures the stability of the overall connection of the decorative rammed earth columns, but also enhances the overall beauty of the decorative molding.

[0032] (2) The present invention adopts a method of pouring from bottom to top layer by layer, which ensures the molding effect of the rammed earth layer, reduces the manufacturing cost of the mold, and reduces the construction difficulty.

[0033] (3) The rammed earth columns produced by the present invention use a decorative support frame as the main support structure, and ramming is performed on the outside of the main support structure to form rammed earth columns with a hollow structure inside. Without affecting the aesthetics of the rammed earth columns, the overall weight of the rammed earth columns is reduced, the production cost of the rammed earth columns is reduced, and the application of rammed earth technology in the field of interior decoration is realized.

[0034] (4) The casting mold of the present invention is made of organic transparent glass, which facilitates the adjustment of the layer, mechanism and color matching of the rammed earth, ensuring that the ramming effect of the rammed earth layer meets the design requirements.

[0035] (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 restrain each other to ensure that the supporting steel frame will not be deformed. At the same time, the flame retardant board and calcium silicate board are coated on the outside of the supporting steel frame, so that the rammed earth column has flame retardant properties while taking into account that the rammed earth material will not enter the interior of the decorative steel frame during the ramming process.

[0050] Example 1

[0051] This embodiment provides a rammed earth column casting device for casting rammed earth columns, which includes a decorative main frame 1, a base panel, a steel mesh 5, vertical reinforcement ribs 6 and a casting mold 9.

[0052] like Figure 1-Figure 2As shown, the decorative main frame 1 is used to form the main structure of the interior decorative rammed earth column. The decorative main frame 1 is connected to the ground with an embedded plate, which is fixed to the ground by chemical bolts. The size of the embedded plate here 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 11 and the wall, and the embedded plate is fixed to the wall by chemical bolts. The size of the embedded plate here is 200*200*8 mm, and the chemical bolts used are RM12 chemical bolts. The embedded plates on the ground and the embedded plates on the wall must be ensured to be firm after installation, and no looseness or hanging is allowed. The main decorative frame 1 is welded from square steel structures and includes 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 tubes. The bottom end of the hot-dip galvanized square tube is welded to the embedded plate set on the ground. The verticality of the supporting square steel 11 is adjusted within the allowable error range, and the welds are treated with rust prevention. The transverse square steel 12 is made of 50*50*5mm hot-dip galvanized square tubes. It is arranged in multiple layers from the bottom right to the top of the supporting square steel 11. The spacing between the transverse square steel 12 layers is 600mm. The transverse square steel 12 is a closed-loop structure, forming the shape of the rammed earth column, including straight segments and arc segments. Angle brackets 2 are embedded in the transverse square steel 12 to facilitate later connection. The spacing between the angle brackets 2 is 400mm, and the specifications of the angle bracket 2 are 50*50*5mm. All welds are treated with rust prevention. The longitudinal square steel 13 connects the transverse square steels 12 between layers. The longitudinal square steel 13 is made of hot-dip galvanized square tubes with a specification of 50*50*5mm. All welding 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. The transverse square steel 12 includes straight segments and arc segments. The arc segments are connected to the supporting square steel 11 through L-shaped square steel 15. The corners of the L-shaped square steel 15 are connected to the arc segments. The plane where the transverse square steel 12 is located 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 in contact with the supporting square steel 11, and one side of part of the longitudinal square steel 13 is in contact with 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, two supporting square steels 11 are provided, and reinforcing square steels 112 are provided between the supporting square steels 11. The reinforcing square steel 112 is welded to the supporting square steel 11, and the reinforcing square steel 112 is a hot-dip galvanized square tube with a specification of 200*400*8mm.

[0053] like Figure 3As shown, the outside of the main decorative frame 1 is surrounded by a base panel, and the outside of the base panel is surrounded by a steel mesh 5. The steel mesh 5 is fixedly connected to the horizontal square steel 12 and the longitudinal square steel 13 by bolts. The end of the angle code 2 passes through the base panel and the steel mesh 5. The base panel can be installed only after the main decorative frame 1 has passed the concealed acceptance inspection. The base panel includes a flame retardant board 3 and a calcium silicate board 4. The flame retardant board 3 is arranged inside the calcium silicate board 4. Due to the plasticity and insufficient nail holding force of the calcium silicate board 4, the base adopts a 15mm thick flame retardant board. The flame retardant board 3 is slotted and bent at the arc position, and fixed to the 50*50*5mm hot-dip galvanized square tube with self-drilling screws. After the flame retardant board 3 is fixed and inspected for flatness, after passing the inspection, the flame retardant board 3 is covered with calcium silicate board 4. The calcium silicate board 4 is cut into strips at the arc position and fixed with automatic screws with a spacing of 150-170mm. The board can be cut manually at the position of the corner code 2. Dust removal equipment should be used to remove dust during cutting. For easy installation, the position of the corner code 2 can be drawn on the base panel before drilling holes. The wire mesh 5 is hung with calcium silicate board 4. The wire mesh 5 is fixed to the main frame with bolts. In order to increase the reliability of 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 the wire mesh 5 are cleaned with steel bars, moistened with water, and the premixed material is gradually and evenly applied to the wire mesh 5. The slurry thrown out each time is uniform and moderate. Vertical reinforcement 6 is welded on the corner code 2. The vertical reinforcement 6 adopts hot-dip galvanized square tube with a specification of 20*20*2. The vertical reinforcement 6 is used to increase the reliability of the vertical reinforcement 6. When welding the vertical reinforcement 6, the verticality of each vertical reinforcement 6 is ensured to be within the allowable error range. The welding point is well treated with rust prevention. The vertical reinforcement 6 and the longitudinal square steel 13 are staggered.

[0054] like Figure 4 As shown, a skirting 7 is provided on the outside of the decorative main frame 1 and on the periphery of the main frame. A gap is formed between the skirting 7 and the decorative main frame 1. The base panel and the wire mesh 5 are located in the gap. The vertical reinforcement ribs 6 and the rammed earth layer 110 are located on the upper part of the skirting 7. The outer edge of the skirting 7 protrudes from the rammed earth layer 110.

[0055] like Figure 5-Figure 6As shown, a casting cavity is formed between the casting mold 9 and the base panel, and the vertical reinforcement rib 6 is located in the casting cavity. The casting mold 9 is fixedly connected to the flame retardant panel 3 by bolts. The casting mold 9 is made of organic transparent glass. In this embodiment, the casting mold 9 is a ring-shaped closed structure formed by horizontally splicing multiple pieces of organic transparent glass. The casting mold 9 includes a flat template 140 and a curved template 130. The outer side of the flat template 140 is provided with an angle steel 10. The angle steel 10 and the flat template 140 are fixedly connected to the flame retardant panel 3 by bolts. The distance between adjacent angle steels 10 is 400 mm. The outer side of the curved template 130 is provided with an arc fixing frame 120. The shape of the arc fixing frame 120 is the same as that of the curved template 130. The arc fixing frame 120 is fixed to the arc fixing frame 120 by bolts. A steel square tube with a specification of 20*20 mm is longitudinally arranged between the arc fixing frame 120 and the curved template 130. The curved template 130 is fixed to the flame retardant panel 3 by bolts. During pouring, the pouring mold 9 is set up from bottom to top, and the pouring mold 9 of the lowest layer is set up on the skirting 7, and the mold is adjusted vertically according to the site boundary line. The on-site mixing of the materials used for the rammed earth layer 110 must be carried out strictly in accordance with the rammed earth material ratio. According to the ratio, the amount of various raw materials for each plate of rammed earth is determined, and the scale standards for rammed earth powder and pebbles are fixed respectively, and the plates are weighed when loading. The loading order should be as follows: first load the rammed earth powder, then the pebbles, and after stirring evenly, add an appropriate amount of water according to the viscosity requirements, and stir with a mixer. The stirring time is determined according to the experimental results of the shortest time for stirring rammed earth. Before loading, the debris in the pouring mold 9 and the oil stains on the vertical reinforcement 6 should be cleaned, and the positional relationship between the vertical reinforcement 6 and the rammed earth layer 110 should be checked. The pouring mold 9 should be evenly coated with a release agent before loading. The mixed rammed earth material can be transported on-site using a wheelbarrow, bucket, or other means. After mixing and unloading, it should be promptly transported to the loading location, and the duration of the rammed earth material should not exceed the initial setting time. Rammed earth material should be added to the mold using a shovel or poured into the mold using a specially designed small hopper. The rammed earth material should be added in layers and compacted gradually, with each layer thickness controlled to 80-150mm. When tamping the rammed earth material, the vertical reinforcements 6 and angle brackets 2 must not be disturbed. The ramming hammer should be checked regularly during tamping to avoid bulging or hollowing. The ramming hammer should be moved less than 100mm apart, and the duration of each hammer strike should be determined by the presence of laitance on the surface. When tamping, pay attention to the wire mesh 5. To prevent missed hammers, tamping must be performed continuously on both sides of the vertical reinforcement bars 6. The rammed earth wall can be removed after 72 hours of setting. After demolding, any holes left by the cast mold 9 on the rammed earth columns should be repaired promptly according to color and mechanical properties, and the finished product should be protected. After the casting mold 9 is removed, it is moved to the top of the rammed earth structure. The lower portion of the casting mold 9 is fitted to the rammed earth structure, and the upper portion is bolted to the flame-retardant plate 3. The casting process is repeated until the casting is complete. The rammed earth column is cured for 14 days in summer and 28 days in winter. After the moisture content is less than 10%, a protective agent is applied.General defects do not require repair. However, for defects such as contamination of rammed earth columns or obvious leakage, appropriate repairs should be completed before applying a protective agent. The protective agent should be diluted with water in a reasonable proportion and stirred evenly. Then, it should be applied by spraying or brushing. Apply two coats, applying the second coat before the first coat is completely dry. The surface must be completely covered without any runny or leaking paint.
