Description

Technical Field

[0001] The invention belongs to the technical field of civil engineering and construction. Background Art

[0002] This prefabricated metal structure building has advanced technology, small process error, stable process quality, and green, energy-saving and environmentally friendly materials. The structure itself is light and strong, generally built with steel or aluminum, and the material recycling rate is high. The components are mass-produced in factories with a high degree of automation. The building space layout is more free.

[0003] There are still many problems with existing steel structure prefabricated buildings. The floor slab is still made of concrete, which is heavy, the beam-column joints have low stiffness, severe stress concentration, poor bending moment and torque transmission, and rigid structural layout. The assembly accuracy is not high. This structure optimizes the stress points, reduces stress concentration, innovates the construction process, and realizes precise assembly of the plate by welding. Summary of the invention

[0004] The present invention adopts a frame node structure with high rigidity, more uniform stress distribution and better robustness under bending moment and torque. At the same time, the floor slab also adopts a metal structure to greatly reduce the dead weight. At the same time, the construction process is improved so that the floor slab and the frame can be precisely welded.

[0005] The specific plan is as follows:

[0006] A novel metal assembly structure can be a metal frame structure or a metal frame composite reinforced concrete cylinder structure. The load-bearing body of the metal frame structure is composed of five major system components: metal node components, metal beam components, metal column components, metal plate components, and metal foundation components. The load-bearing body of the metal frame composite reinforced concrete cylinder structure is composed of six major system components: metal node components, metal beam components, metal column components, metal plate components, metal foundation components, and reinforced concrete cylinder.

[0007] Metal node components can be designed very freely and flexibly to meet more free architectural layout forms. The metal node components can be metal beam-beam node components. That is, the node components used at the intersection of beams. It can also be metal beam-column node components. That is, the node components used at the intersection of beams or columns. The branch rods of metal node components can be beam support rods or column support rods. The angles between beam support rods and beam support rods, beam support rods and column branch rods, and column support rods can be freely designed. The number of beam support rods and column support rods can be freely designed. The cross section of the beam support rod can also be changed according to a certain degree of free design as needed, such as changing the width or thickness of the flange plate, changing the number or height of the web plate, changing the cross-sectional shape, etc.

[0008] It can reliably and evenly transfer the internal force of the frame, and meet the ability of the structure to resist deformation and failure under high floor live load, constant load, earthquake load and wind load. The intersection of the metal node member beam support rod or column support rod adopts a high-rigidity force transmission body connection. That is, a closed section low stress concentration effect and anti-instability welding connection form is adopted.

[0009] Precision assembly can be achieved. All system component joint surfaces must be precisely machined, and after precision machining, each system component can be precisely assembled. In order to offset the influence of welding deformation, except for metal plate components, all frame system components are first welded or pre-assembled with embedded steel bars, and then the assembly surfaces of each component are precisely machined.

[0010] For metal node components, metal beam components, and metal column components, each individual component is welded first and then the assembly surface is precisely processed to achieve compensation for welding deformation and precision assembly.

[0011] For the connection between metal node components, metal beam components, and metal column components, temporary bolts are first assembled, then welded, and then the temporary bolt connection parts are cut and removed. The frame should also be cross-roped to correct welding deformation and increase rigidity as needed, so as to achieve beautiful, reliable and precise appearance while controlling welding deformation.

[0012] For the connection between the metal plate components and the frame, the split assembly is adopted first. After the metal node components, metal beam components and metal column components of this layer are assembled, the metal plate covering the top surface of the metal plate components is assembled first. That is, the topmost metal plate of the metal plate components directly contacting the vertical load used to close the non-porous area floor and roof. This layer of metal plate is first pre-welded on the ground to complete the whole plate, then fixed with a clamp, then hoisted, and then positioned with process bolts, and then marked the area to be cut off, and then hoisted to the ground to cut the plate, and then hoisted for the second time with process bolts Positioning, then surrounding welding, and then removing the process positioning bolts and positioning process connectors and frame cross-tie ropes. After the entire floor and roof of the same layer are welded in sequence, the metal plate covering the top surface of the entire layer of metal plate components is bolted or welded in sequence to the web of the main beam, the web of the secondary beam, the upper additional flange plate of the secondary beam, the lower flange plate of the secondary beam, and the lower flange plate of the main beam. Finally, the metal plate structure assembly support and fixing clamp is removed. Then assemble the next layer of metal frame.

[0013] When the storey height is too high, due to the excessive accumulation of assembly errors and the insufficient rigidity of the pure metal frame structure, a metal frame composite reinforced concrete cylinder structure is used. In addition to the construction content of the metal frame structure, a reinforced concrete cylinder should also be built as needed to resist the lateral deformation of the building body caused by the lateral load and the bottom stress, and the torsional deformation caused by the assembly error, thereby saving metal materials and improving assembly accuracy.

[0014] Anti-rust and anti-corrosion: For rooms in humid environments such as toilets, kitchens, and bathrooms, dissimilar metals can be used to connect and build to prevent corrosion. For humid environments such as toilets, kitchens, and bathrooms in steel structure buildings, each structural member can be built with stainless steel. Other rooms are still made of ordinary structural steel. Dissimilar metal materials can be used to weld the connections between these room components and the surrounding room components.

[0125] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various forms of modifications to the invention by those skilled in the art are all within the scope of the claims attached to this application. A new type of metal structure prefabricated building, the main metal frame structure part includes: metal node components 11, metal beam components 12.1, metal column components 12.2, metal plate components 13, metal foundation components 14; as shown in the attached figure of the specification Figure 3 .

[0126] Metal node component 11, taking the orthogonal four-beam column metal high-rigidity force transmission node component as an example: first use angle steel 112.52041 and steel plate 112.52042 to weld and connect to form metal core force transmission body enclosure component 112.5204 and then reduce the material to make the upper and lower surfaces flat and the welding surface accuracy meets the standard. Figure 12.115 Then, the metal core force transmission body enclosure component 112.5204 and the upper and lower flange cover metal cover plate component 112.51 are welded to form the next step shape, and then this next step shape is welded to the force transmission connection end welding connection web 112.5201, the stiffening rib plate 112.5202, and the cross metal web 112.5203 ​​to form a beam support rod and a high-rigidity force transmission body component 112.5. As shown in the attached figure of the specification Figure 12.111 Then, the beam support rod and high-rigidity force transmission body component 112.5, the welded assembly connection column branch component 112.4, and the metal plate component top surface covered metal plate assembly positioning process connection piece 112.6 are spliced, welded and processed by subtractive processing to form the beam-column node part component 112.01. Figure 11.11203 .

[0127] Metal beam component 12.1, taking the variable cross-section single web H-section beam as an example: the welded beam or the rolled profile beam is manufactured by welding first and then subtractive processing. The two ends of the beam and the upper flange of the beam are precision processed according to the needs to ensure the assembly accuracy. Fig.16 and Figure 18.10 .

[0128] Metal column component 12.2, taking the rectangular square tube section as an example: the upper and lower ends of the column are welded and connected with the end plates using profiled square tubes, and then precision material reduction processing is performed to ensure assembly accuracy. Figure 19.11 , Figure 19.12 , Figure 19.13 .

[0129] Taking the rectangular column base as an example, the metal foundation component 14 is welded and processed by the first step of primary material reduction to process the metal foundation connector 14.1, and the threaded foundation steel bars 30.2 are embedded and tied. Figure 25.2The second step is to assemble and connect the metal foundation connector 14.1 with the pre-buried and tied threaded foundation steel bars 30.2. Figure 25.3 The third step is to pour concrete on the steel bars and maintain them. Figure 25.4 .

[0130] The splicing of metal node components 11 and metal node components 11 or metal beam components 12.1, taking the orthogonal metal frame as an example: the first step is to use bolts to connect the metal beam component 12.1, the node connection plate 17, the pre-spliced ​​flange node connection plate 18, the metal column component or the metal node component 12.2&112, and the metal node component 112. Figure 18.11 The second step is to weld the upper and lower flanges. Figure 18.12 The third step is to remove the pre-joined flange node connecting plate 18 and trim the upper and lower flanges. Figure 18.13 Finally, the frame cross rope 33 is tied as needed to enhance the rigidity. Fig. 27 .

[0131] The splicing of the metal node components 11 and the metal node components 11 or the metal column components 12.2, taking the orthogonal metal frame as an example: the first step is to assemble and connect the metal column components 12.2 and the metal node components 112 with bolts. Figure 19.14 , Figure 19.15 The second step is to weld the weld and remove the process connection parts. Figure 19.16 .

[0132] The connection between the metal node component 11 or the metal column component 12.2 and the metal base component 14, taking the orthogonal metal frame as an example: first use a manual CNC mobile machining center to level the upper surface of the metal base connector 14.1 of each metal base component 14 on the ground, find the precise elevation, find the precise coordinates of the connection bolt holes, and cooperate with the multi-point precision fully automatic steering high magnification aiming level matrix system and the multi-point precision fully automatic steering high magnification aiming total station matrix system and high-precision level to accurately position the CNC machining tool head. Ensure that the upper surface assembly surface position accuracy and shape accuracy of each metal base component 14 are accurate. As shown in the attached figure of the specification Figure 25.5 Then, the metal node member 11 or the metal column member 12.2 is assembled with the metal base member 14 by manual bolts. Figure 25.6 .

[0133] Manufacturing of metal plate components and connection between metal frame and metal plate component 13: The first step is to use split assembly to connect the metal plate component and the frame. After the metal node component 11, metal beam component 12.1, and metal column component 12.2 of this layer are assembled, the metal plate 13.1 is first assembled on the top surface of the metal plate component. That is, the top surface of the metal plate component directly contacts the vertical load for closing the floor and roof of the non-porous area. This layer of metal plate is first pre-welded on the ground to complete the whole plate, then fixed with a clamp, and then hoisted. See the attached figure of the specification. Figure 20.2 , Figure 20.3 , Figure 20.4 , Figure 20.5 The second step is to use process bolts to position. See the attached figure of the instruction manual Figure 20.51 , Figure 20.52 , Figure 20.53 , Figure 20.54 The third step is to mark the area to be cut, then hoist it to the ground and cut the board, and then hoist it again and use the process bolts to position it. See the attached figure of the manual Figure 20.6 , Figure 20.61 The fourth step is to weld and then remove the process positioning bolts and positioning process connectors and frame cross ropes 33. Figure 20.7 , Figure 20.71 , Figure 20.72 , Figure 20.73 , Figure 20.8 . The entire floor and roof of the same layer are welded in sequence. The fifth step is to bolt or weld the metal plate covering the top surface of the entire layer of metal plate components, including the web plate 13.21 of the main beam, the web plate of the secondary beam, the upper additional flange plate of the secondary beam, the lower flange plate of the secondary beam, and the flange plate 13.22 of the lower main beam. Finally, remove the metal plate structure assembly support and fixing fixture. See the attached figure of the instruction manual Figure 20.9 , Figure 20.91 , Figure 20.92 , Figure 20.93 , Figure 20.94 , Figure 20.10 .

[0134] Especially for double web beam connection joints. Figure 15.2 , Figure 15.3 There are two connection methods. Figure 15.2 The connection method is as follows: first, the closed web is enclosed from the end opening to form an inner cavity and a metal support sleeve is inserted, and both ends of each metal support sleeve must be aligned with the bolt holes. Then, the node connection plate 17 and the full-length high-strength bolts on the beam joint are assembled, and the upper and lower flanges are welded.

[0135] Especially for the three-web beam connection joint. Figure 15.4 During assembly: first assemble with bolts and then weld the two outer webs.
