Description

Technical Field

[0001] The present application relates to the field of prefabricated building houses, and in particular to an integrated house adopting a new connection structure. 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] The main structure of light steel structure is generally prefabricated in the factory, and then assembled on site into various buildings according to the design requirements. The various components in the light steel structure are also connected by bolt connection or welding. However, due to the limitation of thread tooth type, the connection strength of bolt connection is relatively low, which is not suitable for thin plate materials. In addition, the structure is easy to loosen under vibration or cyclic load; for the welding connection method, there will be a certain residual stress between the structures, which affects the accuracy and strength of the structure, and the quality of each welding point cannot be guaranteed. It is also necessary to clean the welding slag on the surface of the weld, which is time-consuming and labor-intensive, and prolongs the construction progress.

[0004] In view of the above-mentioned related technologies, the inventor believes that a new connection structure is needed to solve the problems existing in the above-mentioned connection methods. Summary of the invention

[0018] 1. Connecting the main beam and the corner joints through riveted parts can reduce the deformation of the four corners of the transverse frame during connection and reduce the connection error between the corner joints and the columns. In addition, since riveted parts are suitable for thin plate materials, the amount of steel used in the main beam can be reduced. The strength of the steel can also be increased while ensuring that the cost does not increase, thereby improving the overall strength of the house.

[0019] 2. The main beam and the secondary beam are connected by riveting, because a large number of connection points are required. Considering that bolt connection requires threaded holes and gaskets, welding requires later maintenance, cleaning and flaw detection. As a result, the cost of riveting is lower than that of bolt connection and welding on average.

[0020] 3. The light steel keels of the wall frame are connected to each other by riveting. Compared with the existing technology, the wall frame has better ductility when subjected to impact or vibration, is more stable under force without breaking, and is more superior in resisting fatigue cracks at the connection. By performing hippocampal riveting, uniform stress distribution can be provided around the hole. Compared with bolt connections, it has a higher load-bearing capacity and is more reliable in dynamic load and vibration environments.

[0021] 4. Both ends of the light steel pressing sheet are riveted to the vertical light steel keel in the external support frame. The riveting method adopts piercing riveting, which reduces the connection deviation between the light steel pressing sheet and the light steel keel in the wall frame when the wall frame is impacted or vibrated, and the connection between the wall frame and the column is more stable.

[0041] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", "third", etc. or similar expressions are only used for description and distinction purposes, and cannot be understood as indicating or implying the relative importance of the corresponding components.

[0042] The following is combined with Figure 1 -Attached Fig.18 This application is described in further detail.

[0043] The embodiment of the present application discloses an integrated house adopting a new connection structure.

[0044] Reference Figure 1An integrated house adopting a new connection structure includes multiple horizontal structures and multiple vertical structures. The multiple horizontal structures are connected to each other in the horizontal direction to form a floor or roof. In this application, the horizontal structures are 4 groups, thereby forming a larger floor. The vertical structure is connected to the edge of the horizontal structure to form a wall.

[0045] Reference Figure 1-Figure 3 The transverse structure is a main beam 1, a secondary beam 2 and an angle connector 3. Each set of transverse structures has four angle 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 angle 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 angle connectors 3 to form a rectangular frame. The angle 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.

[0046] 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.

[0047] 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.

[0048] Structural rivets are used to withstand high loads and are suitable for structural connections. They generally have a long service life and are suitable for situations where they are subjected to long-term heavy loads.

[0049] 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.

[0050] The two ends of the secondary beam 2 are connected to the long beam 11 by riveting parts. The secondary beam 2 is also provided with a connecting groove 21, in which a connecting beam 22 is arranged. The connecting beam 22 passes through the connecting groove 21 of each secondary beam 2 and is riveted to the short beam 12 at both ends.

[0051] The 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 the flange width of the main beam 1 is preferably 90mm in this embodiment. 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.

[0052] 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.

[0053] Reference Figure 3-Figure 9 The corner joint 3 includes a first corner joint plate 31 and a second corner joint plate 32 which are bent, the bending angle between the first corner joint plate 31 and the second corner joint plate 32 is 90°, and corner extension plates 311 are respectively provided on both sides of the first corner joint plate 31, and the height of the corner extension plates 311 is consistent with that of the first corner joint plate 31.

[0054] Reference Figure 3-Figure 9 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.

[0055] 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.

[0056] Reference Figure 3-Figure 9 The upper and lower ends of the second corner joint plate 32 are respectively provided with ear plates 322 corresponding to the corner piece extension plate 311. The number of the ear plates 322 is four, and they are distributed in pairs at the upper and lower ends of the bent second corner joint plate 32.

[0057] Reference Figure 3-Figure 9 The first corner joint plate 31 and the corner piece extension plate 311 are an integrally formed structure, and the first corner joint plate 31 and the corner piece extension plate 311 can be punched out by a punch press. The second corner joint plate 32 and the ear plate 322 are an integrally formed structure, and the second corner joint plate 32 and the ear plate 322 can also be punched out by a punch press. The ear plate 322 is bent 90° on the second corner joint plate 32, and bending openings 323 are provided at the upper and lower ends of the bending place of the second corner joint plate 32, and the bending opening 323 is arranged to facilitate the bending operation of the ear plate 322.

[0058] Reference Figure 3-Figure 9, the first angle connecting plate 31 is fixed to the second angle connecting plate 32. The first angle connecting plate 31 and the second angle connecting plate 32 are fixed by welding and form a cube with upper and lower openings. Cover plates 33 are welded to the upper and lower ends of the cube respectively. The contour of the cover plate 33 is adapted to the inner peripheral contour of the cube, and the upper and lower cover plates 33 are respectively installed to close the upper and lower openings of the cube.

[0059] Refer to Figure 3-Figure 9 , the periphery of the cover plate 33 is welded to the sides of the first angle connecting plate 31 and the second angle connecting plate 32 in a fitting manner. Chamfers 331 are provided at the four corners of the cover plate 33. Through the setting of the chamfers 331, the cover plate 33 can be better installed on the inner periphery of the column 5, avoiding interference caused by the four corners of the cover plate 33 to its installation.

[0060] A positioning hole 333 is opened in the middle of the cover plate 33. A first mounting hole 332 is provided on the outer periphery of the positioning hole 333. The first mounting hole 332 and the positioning hole 333 are threaded holes.

[0061] Refer to Figure 3-Figure 9 , the ear plate 322 is fixed to the corresponding angle member extension plate 311. Specifically, the ear plate 322 is fixed to the corresponding angle member extension plate 311 by welding, and the upper and lower ends of the angle member extension plate 311 are flush with the corresponding ear plates 322 respectively. The angle member extension plate 311 and its corresponding upper and lower two ear plates 322 cooperate to form a laterally arranged "U" - shaped structure.

[0062] Refer to Figure 3-Figure 9 , through the combined method of stamping and welding, it is convenient for the forming of the angle connector 3, improves the production efficiency of the angle connector 3, reduces the production cost. And when the size of the angle connector 3 needs to be modified, the size of the subsequently produced angle connector 3 can be modified by replacing the stamping die. Compared with the traditional angle connector 3 formed by 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.

[0063] In this application, the thickness of the first angle connecting plate 31 and the second angle connecting plate 32 is 4 mm - 5 mm.

[0064] Refer to Figure 3-Figure 9 , a plurality of angle member countersunk holes 34 are opened on the angle member extension plate 311 and the ear plate 322. The angle member countersunk holes 34 can be used for the fixation of riveting parts, and the angle member countersunk holes 34 are inclinedly distributed on the angle member extension plate 311 and the ear plate 322. By the inclined distribution of the angle member countersunk holes 34, the number of distributions of the angle member countersunk holes 34 is increased, thereby improving the overall structural strength after riveting through the angle member countersunk holes 34. The distance between adjacent angle member countersunk holes 34 is equal.

[0065] The diameter of the corner countersunk hole 34 is 22mm-28mm; in this embodiment, the diameter of the corner countersunk hole 34 is 25mm. The depth of the corner countersunk hole 34 is 3.5mm-5.5mm, and in this embodiment, the depth of the corner countersunk hole 34 is 4.5mm. The countersunk angle of the corner countersunk hole 34 is 130°-140°.

[0066] 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 .

[0067] Taking the long beam 11 as an example, the end of the long beam 11 is sleeved on the outer side of the ear plate 322 and the corner extension plate 311, so that the end of the long beam 11 is fitted with the corner extension plate 311 and the ear plate 322. Specifically, the web of the long beam 11 is fitted with the outer side of the corner extension plate 311, and the flange of the long beam 11 is fitted with the outer side of the ear plate 322.

[0068] Reference Figure 3-Figure 9 The 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, that is, 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 corner piece extension plate 311 and the ear plate 322 are positioned inside and outside in correspondence, 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 corner piece countersunk hole 34, thereby improving the assembly accuracy of this embodiment when in use and ensuring the efficiency and quality of installation.

[0069] Reference Figure 3-Figure 9 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, the depth of the main beam countersunk hole 17 is 3.5mm-5.5mm, and the depth of the main beam countersunk hole 17 in this embodiment is 4.5mm. The main beam countersunk holes 17 of 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.

[0070] 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.

[0071] In the present application, the riveted part is a seahorse rivet, and in other embodiments, the riveted part may also be a piercing rivet.

[0072] Reference Figure 3-Figure 9 Furthermore, when the main beam countersunk holes 17 on the main beam 1 are aligned with the angle member countersunk holes 34 on the angle member extension plate 311 and the ear plate 322, the end of the web of the main beam 1 abuts against the transition section 35, so as to improve the efficiency and accuracy of the main beam 1 during assembly with this embodiment.

[0073] Refer to Figure 3-Figure 9 Moreover, when the main beam countersunk holes 17 on the main beam 1 are aligned with the angle member countersunk holes 34 on the angle member extension plate 311 and the ear plate 322, the main beam countersunk holes 17 on the main beam 1 and the angle member countersunk holes 34 of the angle connector 3 abut and cooperate with each other, so as to increase the abutting area between the angle connector 3 and the main beam 1. Furthermore, when the main beam 1 and the angle connector 3 are fixed by riveting parts, the main beam countersunk holes 17 and the angle member countersunk holes 34 are arranged with internal and external abutment, which can improve the assembly structure strength of the main beam 1 riveted to the angle connector 3.

[0074] Refer to Figure 10-11 The main beam 1 includes a main web 13, a main upper flange 14 and a main lower flange 15. The main upper flange 14 is fixedly connected to the upper end of the main web 13, and the main lower flange 15 is fixedly connected to the lower end of the main web 13. One side of the main upper flange 14 facing the secondary beam 2 is vertically bent downward to form a main upper bent plate 141, and one side of the main lower flange 15 facing the secondary beam 2 is vertically bent upward to form a main lower bent plate 151. The main upper bent plate 141 and the main lower bent plate 151 are mainly provided to connect the main beam 1 and the secondary beam 2 into a whole, so as to achieve more efficient structural connection and functional integration. In addition, a plurality of second mounting holes 16 are equidistantly arranged on the main upper flange 14 and the main lower flange 15. The second mounting holes 16 can facilitate the connection of the main beam 1 with the vertical structure and ensure that the main beam 1 is accurately fixed at the required position.

[0075] Refer to Figure 10-11 The end of the main beam 1 is sleeved on the "U" - shaped structure; the main web 13 and the angle member extension plate 311 are riveted by riveting parts; the main upper flange 14 and the upper ear plate 322 of the angle member extension plate 311 are riveted by riveting parts; the main lower flange 15 and the lower ear plate 322 of the angle member extension plate 311 are riveted by riveting parts.

[0076] 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.

[0077] Reference Figure 10-11 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 .

[0078] Reference Figure 10-11 The secondary beam 2 is a C-shaped groove. The end of the secondary upper flange plate 24 facing the main beam 1 is bent vertically downward to form a secondary upper bent plate 241. The end of the secondary lower flange plate 25 facing the main beam 1 is bent vertically upward to form 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. 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 is bent to form a secondary web bent plate 231. The secondary web bent plate 231 corresponds to the countersunk protrusion 132, and the two are connected by rivets.

[0079] The secondary upper bending plate 241 and the primary upper bending plate 141 are riveted together by rivets.

[0080] The secondary lower bending plate 251 and the primary lower bending plate 151 are riveted together by rivets.

[0081] 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.

[0082] The 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.

[0083] Reference Figure 10-11 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.

[0084] Reference Figure 10-11 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 with 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 in the direction of the secondary beam 2 and is recessed in the direction of 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.

[0085] Reference Figure 10-11 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.

[0086] 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.

[0087] 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.

[0088] 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 .

[0089] The secondary beam 2 is made of C200, C250 or C300 maraging steel material, and its specification is C-shaped steel.

[0090] Reference Figure 10-11 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 parameters of the size specifications 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 for the secondary beam 2.

[0091] The reinforcing beam 27 is an L-shaped steel. Both ends of the web of the reinforcing beam 27 further 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.
