Description

Technical Field

[0001] The present application relates to the field of prefabricated building houses, and in particular to an integrated house assembly molding process. Background Art

[0002] At present, light steel structure is a building form with thin-walled steel components as the main structure. Due to its advantages such as high degree of assembly, superior strength to self-weight ratio, and green environmental protection, it is widely used in the construction industry and is an important structure of integrated houses.

[0003] For prefabricated houses, since most of the components are prefabricated in the factory, only assembly is required on site, which greatly shortens the construction period.

[0041] The following is combined with Figure 1 -Attached Fig.21 This application is described in further detail.

[0042] The embodiment of the present application discloses an integrated house assembly molding process.

The connecting beam 22 passes through the connecting grooves 21 of each secondary beam 2 and is riveted to the short beam 12 at both ends.

[0046] The vertical structure is a column 5 and a wall frame 4; the wall frame 4 includes an outer support frame 41 and an inner support frame 42, and the outer support frame 41 and the inner support frame 42 are both formed by connecting a plurality of light steel keels 40 through riveted parts.

[0047] The wall frame 4 is connected to the column 5 via a wall column connecting assembly 6; the rivet is any one or more of a seahorse rivet, a piercing rivet and a structural rivet.

[0048] Reference Figure 1-Figure 11The main beam 1 is made of C200, C250 or C300 maraging steel, and the specific model of the main beam 1 is single-sided channel steel; the height of the main beam 1 is 280mm-300mm; in this embodiment, the height of the main beam 1 is preferably 300mm, the flange width of the main beam 1 is 90mm-100mm, and in this embodiment, the flange width of the main beam 1 is preferably 90mm. The thickness of the main beam 1 is 2.5mm-3.5mm; in this embodiment, the thickness of the main beam 1 is preferably 4.5mm.

[0049] The long beam 11 and the short beam 12 have the same structure, but are different in length. In other embodiments, the short beams 12 may be connected to each other, or the long beams 11 may be connected to each other, so as to form a square frame.

[0050] The corner connector 3 comprises a first corner connector plate 31 and a second corner connector plate 32 . Corner connector extension plates 311 are respectively disposed on both sides of the first corner connector plate 31 , and the corner connector extension plates 311 are at the same height as the first corner connector plate 31 .

[0051] The first corner plate 31 is provided with a first assembly hole 312, and the first assembly hole 312 is provided so that external accessories can be installed on the first corner plate 31. The second corner plate 32 is provided with a weight-reducing hole 321 corresponding to the position of the first assembly hole 312. The weight-reducing hole 321 can reduce the amount of steel used in the corner connector 3, thereby reducing the deadweight of the structure.

[0052] The second corner plate 32 is provided with ear plates 322 at the upper and lower ends thereof.

[0053] The upper and lower ends of the corner connector 3 are respectively provided with cover plates 33; a positioning hole 333 is opened in the middle of the cover plate 33, and a first mounting hole 332 is provided on the periphery of the positioning hole 333. The first mounting hole 332 and the positioning hole 333 are threaded holes.

[0054] In the present application, the thickness of the first corner plate 31 and the second corner plate 32 is 4 mm to 5 mm.

[0055] A plurality of corner countersunk holes 34 are provided on the corner extension plate 311 and the ear plate 322. The diameter of the corner countersunk holes 34 is 22 mm to 28 mm. In this embodiment, the diameter of the corner countersunk holes 34 is 25 mm. The depth of the corner countersunk holes 34 is 3.5 mm to 5.5 mm. In this embodiment, the depth of the corner countersunk holes 34 is 4.5 mm. The countersunk angle of the corner countersunk holes 34 is 130° to 140°.

[0056] A transition section 35 bent close to the second corner connecting plate 32 is provided between the first corner connecting plate 31 and the corner piece extension plate 311 . By providing the transition section 35 , the corner piece extension plate 311 is closer to the second corner connecting plate 32 .

[0057] Reference Figure 1-Figure 11The main beam 1 is provided with a main beam countersunk hole 17 corresponding to the ear plate 322 and the corner piece extension plate 311. The diameter of the main beam countersunk hole 17 is 16mm-24mm. In this embodiment, the diameter of the main beam countersunk hole 17 is 20mm, and the depth of the main beam countersunk hole 17 is 3.5mm-5.5mm. In this embodiment, the depth of the main beam countersunk hole 17 is 4.5mm. The main beam countersunk holes 17 in two adjacent rows are staggered; the distance between two adjacent main beam countersunk holes 17 is equal. The equal distance can improve the force uniformity of the connection position under external force load.

[0058] Reference Figure 12-13 The main beam 1 includes a main web plate 13, a main upper flange plate 14 and a main lower flange plate 15.

[0059] Reference Figure 12-13 The main upper flange plate 14 is fixedly connected to the upper end of the main web plate 13, and the main lower flange plate 15 is fixedly connected to the lower end of the main web plate 13. The main upper flange plate 14 has a main upper bending plate 141, and the main lower flange plate 15 has a main lower bending plate 151. A plurality of second mounting holes 16 are equidistantly arranged on the main upper flange plate 14 and the main lower flange plate 15. The second mounting holes 16 connect the main beam 1 to the vertical structure through the wall connection assembly, which can ensure that the main beam 1 is accurately fixed at the required position.

[0060] Furthermore, a number of countersunk protrusions 132 are pressed on the main web 13. The countersunk protrusions 132 are waist-shaped, and the upper and lower ends of the countersunk protrusions 132 are arc-shaped. The countersunk depth of the countersunk protrusions 132 is 3.5mm-5.5mm. The arc-shaped design can better disperse stress, reduce stress concentration in the connection part, and reduce the risk of damage to the connection parts due to stress concentration, thereby improving the strength and stability of the connection. The setting of the countersunk protrusions 132 increases the thickness of the main web 13 in disguise, thereby improving the connection strength of the main web 13. Since the countersunk protrusions 132 are directly punched out by a punch press in the factory, the requirements of the connection strength can be met without the need for staff to add stiffening ribs on site, thereby improving assembly efficiency.

[0061] Reference Figure 12-13 The secondary beam 2 includes a secondary web 23 , a secondary upper flange plate 24 and a secondary lower flange plate 25 . The secondary upper flange plate 24 is fixedly connected to the upper end of the secondary web 23 , and the secondary lower flange plate 25 is fixedly connected to the lower end of the secondary web 23 .

[0062] Reference Figure 12-13The secondary beam 2 is a C-shaped groove, the secondary upper flange plate 24 has a secondary upper bent plate 241, the secondary lower flange plate 25 has a secondary upper bent plate 241, the bending lengths of the secondary upper bent plate 241 and the secondary lower bent plate 251 are 30 mm, and the bending length of the primary upper bent plate 141 is the same as that of the secondary upper bent plate 241. The bending length of the primary lower bent plate 151 is the same as that of the secondary lower bent plate 251. The end of the secondary web plate 23 has a secondary web bent plate 231, which corresponds to the countersunk protrusion 132, and the two are connected by a rivet.

[0063] The secondary upper bending plate 241 and the primary upper bending plate 141 are riveted together by rivets.

[0064] The secondary lower bending plate 251 and the primary lower bending plate 151 are riveted together by rivets.

[0065] The rivet is any one or more of a seahorse rivet, a piercing rivet and a structural rivet.

[0066] Seahorse rivets are usually used in situations where high-strength connections are required because they provide good structural integrity. They are mainly made of stainless steel or other corrosion-resistant materials and are suitable for use in harsh environments. Seahorse rivets can form a good seal during installation to prevent liquid or gas leakage. They are also quick to install and can improve production efficiency.

[0067] Piercing rivets can penetrate materials directly without pre-drilling, saving time and labor; the installation process is simple and does not require complicated tools and equipment; and the simple installation process can reduce installation costs.

[0068] Structural rivets are used to withstand high loads and are suitable for structural connections. They usually have a long service life and are suitable for situations where they are subjected to long-term heavy loads.

[0069] Since the selection of each rivet depends on the specific application requirements, including the type of connecting material, required strength, corrosion resistance, installation environment and cost, etc., the riveted parts in this application will select different rivets according to the above application requirements.

[0070] The main beam 1 and the secondary beam 2 are riveted by cold treatment, which avoids the risk of igniting flammable materials during welding, and the riveted connection has better ductility when subjected to impact or vibration; the riveting of the main beam 1 and the secondary beam 2 can be carried out in large-scale batch production, greatly improving the efficiency of the processing process.

[0071] Reference Figure 12-13The riveted parts of the secondary beam 2 and the main beam 1 are piercing rivets. The piercing rivets are driven by the hydraulic piercing rivet punch to pierce the secondary upper bending plate 241 and the secondary lower bending plate 251 respectively. At the same time, the piercing rivets drive the primary upper bending plate 141 and the primary lower bending plate 151 to plastically deform and enter the piercing riveting die. Under the action of the punch and the boss in the hydraulic piercing rivet punch, the legs of the piercing rivet expand to both sides and are respectively embedded in the primary upper bending plate 141 and the primary lower bending plate 151, so that the primary upper bending plate 141 and the secondary upper bending plate 241 are tightly connected, and the primary lower bending plate 151 and the secondary lower bending plate 251 are tightly connected. The secondary upper bending plate 241 is riveted to the primary upper bending plate 141, and the secondary lower bending plate 251 is riveted to the primary lower bending plate 151. This connection method can make the secondary beam 2 have a torsion-resistant effect. It can also prevent the countersunk protrusion 132 and the secondary web bent plate 231 from being loosened after being connected to the main beam 1 and the secondary beam 2, so that the connection between the main beam 1 and the secondary beam 2 is more secure.

[0072] During the riveting process between the secondary web bent plate 231 and the countersunk protrusion 132, the piercing rivet is pre-pressed toward the main web 13 under the drive of the hydraulic piercing rivet punch; the hydraulic piercing rivet punch can push the piercing rivet during the movement to force it to pierce the countersunk protrusion 132, and at the same time, the piercing rivet can cause the secondary web bent plate 231 to undergo plastic deformation and enter the piercing riveting die.

[0073] Taking piercing riveting as an example, as the riveting proceeds, the secondary web bent plate 231 gradually fills into the piercing riveting die due to plastic deformation. The piercing riveting die has a punch and a boss. Under the action of the punch and the boss, the legs of the piercing rivet expand to both sides and embed into the secondary web bent plate 231, so that the piercing rivet is tightly connected to the countersunk protrusion 132 and the secondary web bent plate 231. The secondary web bent plate 231 is riveted on the countersunk protrusion 132, so that the connection tightness and tightness of the main beam 1 and the secondary beam 2 are stronger and can withstand greater pressure. The countersunk protrusion 132 is pressed and formed by a machine tool, so that it presents a structure that protrudes toward the secondary beam 2 and is recessed away from the secondary beam 2. This method can increase the thickness of the connection point of the main beam 1, thereby increasing the connection strength. This can not only make the connection between the main beam 1 and the secondary beam 2 tighter.

[0074] When the riveted part is a seahorse rivet, a plurality of rivet holes 131 for the seahorse rivet to pass through are arranged between the countersunk protrusion 132 and the secondary web bent plate 231. In this embodiment, there are three rivet holes 131. A plurality of rivet holes 131 with equal distances can better disperse and withstand external forces, thereby improving the stability and safety of the connection between the main beam 1 and the secondary beam 2, and higher strength steel can be used to adapt to the structural system.

[0075] The end of the secondary web 23 is in the shape of an isosceles trapezoid. This connection method can prevent the secondary beam 2 from contacting the connection position between the main web 13 and the main upper flange plate 14 or the lower flange plate, thereby reducing stress concentration and improving the stability and bearing capacity of the entire structure.

[0076] The spacing between adjacent secondary beams 2 is 350mm-450mm. The connecting groove 21 of the secondary beam 2 has a curling edge 28, and the connecting beam 22 is a channel steel. The upper flange and the lower flange of the connecting beam 22 are fixedly connected to the curling edge 28. The connecting groove 21 is a waist-shaped hole, and the length of the waist-shaped hole is 80mm-120mm. The connecting beam 22 is C150 maraging steel.

[0077] The webs at both ends of the connecting beam 22 are extended and bent to form a first bent plate 222 , and the first bent plate 222 is riveted to the countersunk protrusion 132 on the main beam 1 .

[0078] The secondary beam 2 is made of C200, C250 or C300 maraging steel material, and its specification is C-shaped steel.

[0079] Reference Figure 12-13 In order to improve the strength of the connection between the long beam 11 and the short beam 12, a reinforcing beam 27 is fixed at the connection between the long beam 11 and the short beam 12. The secondary beam 2 is also provided with a through opening 26, and the reinforcing beam 27 passes through the through opening 26 and is connected to the long beam 11 and the short beam 12 at both ends. In order to reduce the preparation of additional equipment for the secondary beam 2, the size and specification parameters of the through opening 26 and the connecting groove 21 are designed to be the same. Therefore, one device can be used to open the through opening 26 and the connecting groove 21 on the secondary beam 2.

[0080] The reinforcing beam 27 is an L-shaped steel. The two ends of the web of the reinforcing beam 27 also have second bent plates 271 . The second bent plates 271 are fixedly connected to the countersunk protrusions 132 on the long beam 11 and the short beam 12 , respectively.

[0081] Reference Figure 14-Figure 21 The outer support frame 41 is a circular structure assembled by two horizontal light steel keels 40 and two vertical light steel keels 40, the horizontal light steel keels 40 and the vertical light steel keels 40 are connected by rivets, the vertical light steel keels 40 and the columns 5 are connected by wall column connection components 6, and the horizontal light steel keels 40 and the main beam 1 are connected by wall column connection components 6. The interior of the outer support frame 41 is supported by the inner support frame 42.

[0082] When the transverse structure serves as the roof, the wall column connection assembly 6 is connected to the transverse light steel keel 40 through the second mounting hole 16 on the main lower flange plate 15 .

[0083] When the transverse structure is used as a floor, the wall column connection assembly 6 is connected to the transverse light steel keel 40 through the second mounting hole 16 on the main upper flange plate 14 .

[0084] Personnel can adjust the structural style of the inner support frame 42 according to actual applications.

[0085] Reference Figure 14-Figure 21 The length and size of the light steel keel 40 can be adjusted by the assemblers according to the actual application. The matching connection points of each group of light steel keels 40 are riveted together by seahorse rivets or piercing rivets. Compared with the screw connection method using bolts and nuts, it has high tensile and shear resistance and strong anti-vibration connection performance.

[0086] In the above embodiment, the light steel keels 40 of the wall frame 4 are connected to each other by riveting. Compared with the prior art, the wall frame 4 has better ductility when subjected to impact or vibration, is more stable under stress without breaking, and is more superior in resisting fatigue cracks at the connection. By performing hippocampal riveting, a uniform stress distribution can be provided around the hole. Compared with the connection of bolts, the load-bearing capacity is higher and it is more reliable under dynamic load and vibration environment. At the same time, an inner OSB board 442 is arranged on the wall frame 4 to cooperate with the gypsum board 441 as The inner wall layer 44 has the characteristics of anti-deformation, anti-peeling, uniform strength, stable size, low formaldehyde emission, safety and environmental protection. The outer OSB board 433, the one-way breathing paper 432 and the metal carved board 431 are arranged as the outer wall layer 43, so that the outer wall layer 43 has the characteristics of anti-deformation, uniform strength, low formaldehyde emission, and good waterproof and breathable effect, which can prevent rain or snow water from penetrating from the wind. The metal carved board 431 can be used to provide good sound insulation effect and have a certain impact resistance.

[0087] The column 5 is a square tube column with a hollow structure. Connecting seats 51 are disposed opposite to each other at the upper and lower ends of the column 5 . The connecting seats 51 are prepared by casting.

[0088] The casting method can achieve high dimensional accuracy and good surface finish, and improve the fit with the column 5. The column 5 and the connecting seat 51 are connected by welding. Welding can make the two more firmly connected. The whole can withstand greater force and load, and is used to support higher reliability. The hollow setting of the column 5 also further reduces the weight of the structure.

[0089] Reference Figure 14-Figure 21A corner column bolt 53 is provided at the upper end of the connecting seat 51. The corner column bolt 53 is an M16 hexagon socket bolt. The corner column bolt 53 is adapted to the aperture of the first mounting hole 332. The connecting seat 51 is threadedly connected to the corner connector 3 through the corner column bolt 53. The threaded connection setting method can facilitate personnel to assemble the parts separately and quickly install and position them. A plurality of makeshift grooves 52 are opened on the column 5 along its length direction. The size of the makeshift grooves 52 can be adjusted according to the actual application of the personnel. The purpose is to facilitate personnel to check its internal situation and to facilitate personnel to operate to connect the column 5 with the external support frame 41 through the wall column connection assembly 6. The wall column connection assembly 6 is provided with a plurality of groups, which can improve the stability of the connection between the two.

[0090] In the above embodiment, columns 5 are provided between the outer support frames 41 of adjacent wall frames 4, and the columns 5 are positioned, connected and supported with the upper and lower corner connectors 3 respectively through the supports at the upper and lower ends thereof. The outer support frames 41 of the wall frames 4 and the columns 5 are screwed together through the wall column connecting components 6. Compared with the prior art, the wall frames 4 cooperate with the columns 5 to be connected with the horizontal structure, so that the vertical structure is more stable when subjected to impact or vibration, and the columns 5 can play a certain dispersing role. At the same time, a clearance groove 52 is provided on the column 5 to facilitate personnel to adjust the connection between it and the wall frame 4, that is, to facilitate the wall column connecting components 6, thereby facilitating the disassembly and assembly of the wall frame 4 for maintenance and adjustment.

[0091] The wall column connection assembly 6 comprises a light steel pressing sheet 61 , a light steel gasket 62 , a fastening gasket 63 and a wall column bolt 64 , wherein a notch 621 is formed on one side of the light steel gasket 62 .

[0092] Reference Figure 14-Figure 21 A light steel pressing sheet 61 is arranged on the inner wall of the wall frame 4 and close to the column 5. A thread is provided in the middle of the light steel pressing sheet 61 (not shown in the drawings). A wall column bolt 64 which is screwed with the thread is passed through the inside of the column 5 toward the side of the light steel pressing sheet 61. Several groups of wall column bolts 64 are arranged, which are opposite to the light steel pressing sheets 61 of each group. A through hole is provided on the inner wall of the light steel keel 40 for the bottom end of the wall column bolt 64 to pass through (not shown in the drawings).

[0093] Reference Figure 14-Figure 21 The light steel gasket 62 is located between the wall frame 4 and the column 5. In this embodiment, a U-shaped groove 621 is opened on the light steel gasket 62, and its internal size is larger than the outer diameter of the bottom end of the wall column bolt 64. Its purpose is to facilitate the installer to remove or insert the light steel gasket 62 after tightening a part of the thread of the wall column bolt 64. A fastening gasket 63 is sleeved on one end of the wall column bolt 64 located inside the column 5. Its purpose is to increase the contact area between the wall column bolt 64 and the column 5, increase friction, and reduce the impact of external vibration on it.

[0094] The two ends of the light steel pressing sheet 61 are riveted to the vertical light steel keel 40 in the outer support frame 41, and the riveting method adopts piercing riveting, which reduces the connection deviation between the light steel pressing sheet 61 and the light steel keel 40 in the wall frame 4 when the wall frame 4 is impacted or vibrated, and the connection between the wall frame 4 and the column 5 is more stable.

[0095] Reference Figure 14-Figure 21 , by riveting a light steel pressing sheet 61 on the inner wall of the outer support frame 41, a thread is provided on the light steel pressing sheet 61, and a wall column bolt 64 that is screwed with the thread is passed through the column 5, and a light steel gasket 62 is provided at one end of the wall column bolt 64 between the wall frame 4 and the column 5. Compared with the prior art, the connection stability between the wall frame 4 and the column 5 is improved, and a slot 621 is provided on the light steel pressing sheet 61 for personnel to conveniently insert or remove from one side of the wall column bolt 64. The light steel pressing sheet 61 is riveted to the wall frame 4 by piercing riveting. Compared with the screw connection of bolts and nuts, the light steel pressing sheet 61 can be more effectively fixed on the wall frame 4, avoiding the separation of the two caused by vibration, thereby affecting the connection stability between the two.

[0096] Specific process steps:

[0097] 1. Build foundation: Pour concrete at the location where the column foot 72 needs to be installed to form an independent foundation 7. After the concrete pouring is completed, the anchor bolts 71 are pre-buried. In other embodiments, the anchor bolts 71 can be replaced with chemical anchor bolts according to the environment, site and size of the prefabricated house.

[0098] The column foot 72 is prefabricated in the factory, set out on site according to the drawings, and connected to the independent foundation 7 using the anchor bolts 71 / chemical anchor bolts.

[0099] The anchor bolts 71 on the independent foundation 7 are fixedly connected with the column foot 72, and then the ground is poured again for 100mm to be flattened, and the stiffening plate 73 of the column foot 72 is covered (buried 100mm below the foundation). The independent foundation 7 and the column foot 72 form a whole as the foundation of the integrated house.

[0100] 2. Install horizontal and vertical structures on the foundation.

[0101] After the column foot 72 is prefabricated, the horizontal structure is first installed on the foundation to form the first floor slab, and then the vertical structure is installed on the first floor slab to form the first floor wallboard. The horizontal structure is then installed on the top of the first floor wallboard to form the second floor slab, and then the vertical structure is installed on the second floor slab to form the second floor wallboard, and so on to build a multi-story integrated house.

[0102] When the length and / or width of the integrated house needs to be increased, multiple transverse structures are connected horizontally. In this application, there are 4 transverse structures, and the corner joints 3 of adjacent transverse structures are fixedly connected by bolts. The vertical structure is connected to the edge of the transverse structure to form a wall.

[0103] Each set of transverse structures has four corner connectors 3 and four main beams 1, of which two main beams 1 are long beams 11, and the other two main beams 1 are short beams 12. The corner connectors 3 are used to connect the long beams 11 and the short beams 12. The two long beams 11 and the two short beams 12 are surrounded by four corner connectors 3 to form a rectangular frame, and the corner connectors 3 are riveted to the main beams 1 by rivets. The rivets are any one or more of seahorse rivets, piercing rivets and structural rivets.

[0104] When the transverse structure is used as a floor, cement fiber boards are pre-laid on the upper and lower surfaces of the transverse structure. The lower end of the corner connector 3 is fixedly connected to the column foot 72 .

[0105] The upper end of the corner connector 3 is connected to the column 5 of the upper vertical structure.

[0106] When the horizontal structure is used as the second floor or above, the horizontal structure can be pre-installed with an insulation layer on the basis of pre-laid cement fiber board. At this time, the upper end of the corner joint 3 is connected to the column 5 in the upper vertical structure. The lower end of the corner joint 3 is connected to the column 5 in the lower vertical structure.

[0107] 3. Assemble the main beam 1 and the corner joint 3.

[0108] 3.1 Assembly of the diagonal connector 3, the first corner connector plate 31 and the second corner connector plate 32 are bent at a bending angle of 90°. The first corner connector plate 31 and the corner extension plate 311 are an integrally formed structure, which are punched out by a punch press, the second corner connector plate 32 and the ear plate 322 are an integrally formed structure, which are also punched out by a punch press, the ear plate 322 is bent 90° on the second corner connector plate 32, and the upper and lower ends of the second corner connector plate 32 are provided with bending openings 323, which are arranged to facilitate the bending operation of the ear plate 322.

[0109] The external accessory described in this embodiment is another corner connector 3. When the width and length of the house need to be increased, the two transverse structures are horizontally connected to each other. At this time, the first assembly hole 312 of the corner connector 3 in one transverse structure and the first assembly hole 312 of the corner connector 3 in the other transverse structure are aligned with each other, and then tightened and connected by bolts.

[0110] The first corner joint plate 31 is fixed to the second corner joint plate 32, and the first corner joint plate 31 and the second corner joint plate 32 are welded and fixed to form a cube with upper and lower openings. The cover plate 33 is welded to the upper and lower ends of the corner joint 3, and the contour of the cover plate 33 is adapted to the inner circumferential contour of the cube. The upper and lower cover plates 33 are respectively installed to close the upper and lower openings of the cube.

[0111] The perimeter of the cover plate 33 is adhesively welded to the sides of the first angle connecting plate 31 and the second angle connecting plate 32. Chamfers 331 are provided at the four corners of the cover plate 33. By setting the chamfers 331, the cover plate 33 can be better installed on the inner perimeter of the cube, avoiding interference caused by the four corners of the cover plate 33 during installation.

[0112] The number of the ear plates 322 is four, and they are distributed in pairs, two on the upper and lower ends of the bent second angle connecting plate 32.

[0113] The ear plates 322 are fixed to the corresponding angle part extension plates 311. Specifically, the ear plates 322 are welded and fixed to the corresponding angle part extension plates 311, and the upper and lower ends of the angle part extension plates 311 are flush with the corresponding ear plates 322 respectively. The angle part extension plates 311 cooperate with the upper and lower two corresponding ear plates 322 to form a laterally arranged "U" - shaped structure.

[0114] Through the cooperation method of stamping and welding, it is convenient for the forming of the angle connector 3, improving the production efficiency of the angle connector 3, reducing the production cost. And when the size of the angle connector 3 needs to be modified, the size of the subsequently manufactured angle connector 3 can be modified by replacing the stamping die. Compared with the angle connector 3 formed by traditional casting, the angle connector 3 in this embodiment is more convenient for processing and manufacturing, has stronger adaptability, and is easier to adjust the size.

[0115] The angle part counterbore holes 34 can be used for fixing riveting parts, and the angle part counterbore holes 34 are inclined and distributed on the angle part extension plates 311 and the ear plates 322. By the inclined distribution of the angle part counterbore holes 34, the number of distributed angle part counterbore holes 34 is increased, thereby improving the overall structural strength after riveting through the angle part counterbore holes 34. The distance between adjacent angle part counterbore holes 34 is equal.

[0116] 3.2. The assembled angle connector 3 is connected to the main beam 1:

[0117] Taking the long beam 11 as an example, the end of the long beam 11 is sleeved outside the ear plates 322 and the angle part extension plates 311, and the end of the long beam 11 is arranged in contact with the angle part extension plates 311 and the ear plates 322. Specifically, the web of the long beam 11 is in contact with the outside of the angle part extension plates 311, and the flange of the long beam 11 is in contact with the outside of the ear plates 322.

[0118] The main beam countersunk hole 17 on the main beam 1 corresponds to the position of the corner piece countersunk hole 34 on the corner piece extension plate 311, and the main beam countersunk hole 17 on the main beam 1 corresponds to the position of the corner piece countersunk hole 34 on the ear plate 322. Then, when the end of the main beam 1 is sleeved on the outside of the ear plate 322 and the corner piece extension plate 311, the main beam countersunk hole 17 on the main beam 1 and the corner piece countersunk hole 34 on the angle piece extension plate 311 and the ear plate 322 are positioned correspondingly inside and outside, so that the main beam 1 and the corner connector 3 can be quickly positioned and riveted through the corresponding main beam countersunk hole 17 and the angle piece countersunk hole 34, thereby improving the assembly accuracy of this embodiment when in use and ensuring the efficiency and quality of installation.

[0119] After the corner connector 3 and the main beam 1 are prefabricated and transported to the site, the countersunk hole 34 of the corner connector and the countersunk hole 17 of the main beam are butted together, and then the corner connector 3 and the main beam 1 are connected by riveting.

[0120] In the present application, the riveted part is a seahorse rivet, and in other embodiments, the riveted part may also be a piercing rivet.

[0121] Furthermore, when the main beam countersunk hole 17 on the main beam 1 is positioned correspondingly to the corner piece countersunk hole 34 on the corner piece extension plate 311 and the ear plate 322, the web end of the main beam 1 abuts against the transition section 35 to improve the efficiency and accuracy of the main beam 1 when assembled with this embodiment.

[0122] When the main beam countersunk hole 17 on the main beam 1 corresponds to the corner piece countersunk hole 34 on the corner piece extension plate 311 and the ear plate 322, the main beam countersunk hole 17 of the main beam 1 and the corner piece countersunk hole 34 of the corner piece 3 abut against each other to increase the abutment area between the corner piece 3 and the main beam 1. When the main beam 1 and the corner piece 3 are fixed by riveting parts, the main beam countersunk hole 17 and the corner piece countersunk hole 34 are arranged in abutment with each other inside and outside, which can improve the assembly structural strength of the main beam 1 riveted to the corner piece 3.

[0123] The main upper flange plate 14 is bent vertically downward on one side facing the secondary beam 2 to form a main upper bent plate 141, and the main lower flange plate 15 is bent vertically upward on one side facing the secondary beam 2 to form a main lower bent plate 151. The main upper bent plate 141 and the main lower bent plate 151 are mainly arranged to connect the main beam 1 and the secondary beam 2 as a whole, thereby achieving more efficient structural connection and functional integration. In addition, a plurality of second mounting holes 16 are equidistantly arranged on the main upper flange plate 14 and the main lower flange plate 15. The arrangement of the second mounting holes 16 can facilitate the connection of the main beam 1 with the vertical structure, and can ensure that the main beam 1 is accurately fixed at the required position.

[0124] The end of the main beam 1 is sleeved in the "U"-shaped structure; the main web 13 is riveted to the angle piece extension plate 311 by a riveting piece; the main upper flange plate 14 is riveted to the upper ear plate 322 of the angle piece extension plate 311 by a riveting piece; the main lower flange plate 15 is riveted to the lower ear plate 322 of the angle piece extension plate 311 by a riveting piece.

The bending lengths of the secondary upper bent plate 241 and the secondary lower bent plate 251 are 30 mm, and the bending length of the main upper bent plate 141 is the same as that of the secondary upper bent plate 241. The bending length of the main lower bent plate 151 is the same as that of the secondary lower bent plate 251.

[0128] 4.3. Connection and forming of the main and secondary beams 2:

[0129] The end of the secondary web 23 is bent to form a secondary web bent plate 231, which corresponds to the countersunk head protrusion 132, and the two are connected by a riveting piece.

[0130] The secondary upper bent plate 241 is riveted to the main upper bent plate 141 by a riveting piece.
