Description

Technical Field

[0001] This invention relates to the field of construction, and more particularly to a vertical frame, a connector, and a mortise and tenon joint frame structure using the vertical frame and connector. Background Technology

[0002] In a modular frame structure system, the connection method between components is the core technology. Components typically include vertical frames, horizontal frames, connectors, and fixing members. Vertical frames are generally made of closed-cavity material, while horizontal frames include both open-cavity and closed-cavity materials. Connectors mainly come in two basic forms: angle brackets and inserts. Connectors are often connected or fixed to the vertical frames using fixing members. Frame structures with open-cavity horizontal frames have poorer structural strength and require more profiles; frame structures with closed-cavity horizontal frames have better structural strength and require less profiles, but the components must be installed sequentially, making construction more difficult.

[0003] In terms of the structure of the frame in the current technology, the horizontal frame cannot achieve true floating. Over time, under the action of thermal expansion and contraction and other external forces, the frame nodes are prone to loosening, fatigue and breakage, which poses a safety hazard under extremely unfavorable conditions.

[0004] In terms of construction and installation, the connection between the connector and the vertical frame often requires on-site measurement, positioning and drilling, which places high demands on the technical skills of on-site construction personnel. The construction quality is greatly affected by human factors, which in turn affects construction efficiency and poses safety hazards to the building.

[0005] In summary, there is currently no high-performance frame structure system available in the industry, resulting in inconsistent standards and technical confusion in the field. This hinders the realization of fully automated production and processing of components and high-standard, rapid installation of frame structures, failing to meet the needs of industry development.

[0038] 2. The frame structure system provided by this invention has simple installation and operation. Because the vertical frame has a precisely positioned assembly opening, there are no technical steps such as on-site measurement, drilling, and fixing when installing the horizontal frame. This simplifies the installation process, reduces construction difficulty, and minimizes the adverse effects of human factors on the frame installation quality. Therefore, the assembly quality of the frame structure is guaranteed from the perspective of installation process.

[0039] 3. The frame structure system provided by this invention has extremely high safety. Because the connectors are connected to the vertical and horizontal frames using mortise and tenon joints, the bearing surface of the opening of the vertical frame is the cut surface of the vertical frame material itself. The load of the horizontal frame is transferred to the vertical frame through the connectors without any loose connection structure or easily fatigued nodes. Furthermore, due to the flexible connection structure of the horizontal frame, the frame structure has multi-dimensional structural deformation capabilities.

[0040] 4. The frame structure system provided by this invention has perfect leak-proof performance. In the frame structure, the end of the horizontal frame joint cavity is inserted into the shoulder cavity of the vertical frame to form a transverse water collection leak-proof structure; when the vertical frames are connected vertically, the guide groove of the insert core is connected with the outer groove of the main body shoulder of the vertical frame to form a longitudinal drainage leak-proof structure. Therefore, the frame structure forms a longitudinally and transversely arranged structural leak-proof and drainage system.

[0041] 5. The frame structure system provided by this invention has good applicability. Because it uses transition components to connect the panels and the frame structure, different transition components can be used to connect different panels to form building envelopes with different properties and different forms of expression, thus making it suitable for a wide range of building applications and social needs.

[0078] The vertical frame 1 of the present invention is characterized in that it includes a main body 2, and a mounting part 11 is provided on one side of the main body 2 through a protrusion 8.

[0079] The mounting portion 11 includes a secondary cavity 5 disposed on the side of the protrusion 8.

[0080] The surface of the main body 2 is provided with an opening 30, which forms an insertion port on the outside of the sub-cavity 5. At the same time, the intersecting surface of the opening 30 and the main body 2 forms two mating surfaces 21. By processing the opening 30, the vertical frame 1 forms a connecting structure, which facilitates high-precision processing in the factory. During installation, no on-site measurement by construction personnel is required, making the operation simple, efficient, and ensuring installation accuracy.

[0081] After the opening 30 mates with the connector 12, it can simultaneously fix the connector 12 in both the horizontal and vertical directions, resulting in a reasonable structure and convenient installation. Sub-cavities 5 are provided on both sides of the protrusion 8; this form of vertical frame 1 can be used as a vertical frame 1 within a frame. Alternatively, the protrusion 8 may have a sub-cavity 5 on only one side; this type of vertical frame 1 with a sub-cavity 5 on one side can be used as a vertical frame 1 on the edge of a frame.

[0082] The surface of the secondary cavity 5 is provided with a first adhesive strip groove 32. The end face of the secondary cavity 5 serves to support the connector 12 while being machined into the first adhesive strip groove 32, making reasonable use of the profile space. One structure achieves two purposes, saving space and profile costs.

[0083] The protruding part 8 of the main body 2 has a shoulder on its side, and a top edge 3 is provided at the edge of the shoulder. The top edge 3 cooperates with the second support boss 16 of the connector 12 to position the horizontal frame 31 and ensure the reliable connection of the horizontal frame 31.

[0084] The outer wall of the sub-cavity 5 is provided with a slot 6. When using the split shoulder corner 4, the slot 6 can cooperate with the shoulder corner 4, and at the same time, it can cooperate with the elastic plate 17 of the connector 12.

[0085] The secondary cavity 5 is provided with a mating groove 29.

[0086] The main body 2 has an inner groove 9 corresponding to the shoulder edge; the main cavity 34 of the main body 2 has a core 22, and the core 22 has a first burr 23 that mates with the inner groove 9; the outer contour of the core 22 has a protruding ridge 24 that contacts the inner wall of the vertical frame 1. By setting the core 22 between adjacent vertical frames 1, condensate or rainwater can be effectively prevented from entering the interior of the vertical frame 1.

[0087] A groove 10 is provided at the shoulder. The groove 10 is used to cooperate with the split shoulder corner body 4. At the same time, the outer wall of the groove 10 can be the top edge 3 of the vertical frame 1, making reasonable use of the limited internal space of the profile.

[0088] The two sides of the shoulder corner 4 of the vertical frame 1 of the present invention are respectively matched with the slot 6 and the groove 10.

[0089] The shoulder corner body 4 and the vertical frame 1 are an integral structure. The cavity formed by the shoulder corner body 4 and the vertical frame 1 can be used for drainage.

[0090] The split-type shoulder corner body 4 structure allows a shoulder cavity 35 to be formed between the protrusion 8 of the vertical frame 1 and the shoulder corner body 4. The shoulder cavity 35 can be used for wiring or drainage.

[0091] In addition, the split-type shoulder corner body 4 facilitates the processing of the opening 30. The opening 30 of the main body 2 of the vertical frame 1 protrudes from the profile surface, allowing direct milling of the main body 2, as shown in milling position 33. When the shoulder corner body 4 and the vertical frame 1 are an integral structure, the processing of the opening 30 requires avoiding the structure of the shoulder corner body 4.

[0092] The connector 12 of the present invention, which cooperates with the above-mentioned vertical frame 1, is characterized in that: it includes a connector 15 that cooperates with the opening 30 of the mounting part 11 of the vertical frame 1, and a plug-in part 18 is provided on the side of the connector 15.

[0093] The connecting part 15 includes a first vertical plate 13 that mates with the sub-cavity 5 and a support part 14 that corresponds to the mating surface 21. The first vertical plate 13 is inserted into the sub-cavity 5 of the vertical frame 1, and the sub-cavity 5 restricts the lateral displacement of the first vertical plate 13. The support part 14 is inserted into the opening 30 of the vertical frame 1, and the position of the support part 14 is restricted by the opening 30, so that the connecting part 12 and the vertical frame 1 form a two-way interlocking structure, which makes the curtain wall frame node stable and not limited by the installation angle of the curtain wall frame node, thus ensuring high reliability.

[0094] The support portion 14 is provided with a second adhesive strip groove 63 corresponding to the first adhesive strip groove 32.

[0095] The connector 12 has a plug-in portion 18 connected to the first vertical plate 13. A first support boss 20 is provided on the end face of the plug-in portion 18. A second support boss 16 corresponding to the top edge 3 of the vertical frame 1 is provided on the side surface of the plug-in portion 18. The first support boss 20 can support the horizontal frame. The second support boss 16 and the top edge 3 of the vertical beam form a line contact with the horizontal beam, providing a fulcrum for the horizontal frame and facilitating the deformation and adjustment of the horizontal frame.

[0096] The insertion part 18 is a U-shaped body 19 connected at one end to the first vertical plate 13. The first support boss 20 is disposed on the end face of the U-shaped body 19; the second support boss 16 is disposed on the side surface of the U-shaped body 19. Setting the insertion part 18 as a U-shaped body 19 provides reasonable stress distribution and high safety. In extreme cases, the insertion part 18 can be set as an L-shape, with the first support boss 20 and the second support boss 16 on the two sides of one side of the L-shaped insertion part 18.

[0097] An elastic plate 17 is provided at the opening of the U-shaped body 19 of the connector 12, and the elastic plate 17 cooperates with the slot 6 of the vertical frame 1. The structure of the elastic plate 17 cooperates with the structure of the vertical frame 1 to achieve tool-free installation, which greatly improves the work efficiency of on-site workers and reduces labor intensity. The accuracy of each component of the curtain wall frame has been guaranteed at the factory, and there is no need for workers to measure on-site.

[0098] The first support boss 20 is composed of an overlapping block 64 that overlaps the end face of the insertion part 18.

[0099] The first support boss 20 is a roller 67, and the insertion part 18 is provided with a guide groove 68. The roller 67 rolls in cooperation with the guide groove 68. The first support boss 20 in the form of a roller 67 is suitable for large curtain wall frame structures. When the horizontal frame 31 undergoes thermal expansion and contraction or other deformations, the roller 67 rolls in the guide groove 68, which can absorb the displacement of the horizontal frame 31 and eliminate or reduce noise.

[0100] The first vertical plate 13 is provided with a mating protrusion 27, which mates with the mating groove 29 in the secondary cavity 5 of the vertical frame 1. The first vertical plate 13 is provided with a locking piece 28 that mates with the secondary cavity 5 on its side.

[0101] This invention utilizes the aforementioned curtain wall frame node structure of vertical frame 1 and connector 12, and further includes a horizontal frame 31. The horizontal frame 31 is characterized by having an insertion cavity 42 within it, into which the insertion portion 18 of connector 12 is inserted; the first vertical plate 13 of connector 12 is inserted into the secondary cavity 5 of vertical frame 1; and the support portion 14 of connector 12 engages with the opening 30 of vertical frame 1. When vertical frame 1 is vertically positioned and horizontal frame 31 is horizontally positioned, the mating surface 21 at the lower part of opening 30 is the main load-bearing component. When horizontal frame 31 and vertical frame 1 are at a certain angle, due to the mating relationship between mating surface 21 and support portion 14, the upper and lower mating surfaces 21 share the load, ensuring structural stability.

[0102] The insertion part 18 of the connector 12 is a U-shaped body 19 connected to the first vertical plate 13 at one end. A second support boss 16 is provided on the side surface of the U-shaped body 19. A first support boss 20 is provided on the end face of the U-shaped body 19. The second support boss 16 of the connector 12 contacts the inner wall of the insertion cavity 42 of the horizontal frame 31. The top edge 3 of the vertical frame 1 contacts the outer wall of the insertion cavity 42. The contact points of the second support boss 16 and the top edge 3 with the horizontal frame 31 are corresponding. The first support boss 20 of the connector 12 contacts the inner wall of the insertion cavity 42 of the horizontal frame 31.

[0103] The first vertical plate 13 on the connector 12 is inserted into the secondary cavity 5, and the support part 14 of the connector 12 is inserted into the opening 30 of the vertical frame 1.

[0104] The first vertical plate 13 of the connector 12 is provided with a mating protrusion 27. The first vertical plate 13 with the mating protrusion 27 is inserted into the secondary cavity 5. The secondary cavity 5 is provided with a mating groove 29 that mates with the mating protrusion 27. A locking piece 28 that fits against the first vertical plate 13 is inserted into the other side of the secondary cavity 5.

[0105] It also includes a shoulder corner body 4, on which a machined end face 62 is provided, corresponding to the mating surface 21 of the opening 30.

[0106] The shoulder corner body 4 and the main body 2 are an integral structure.

[0107] The shoulder corner body 4 and the main body 2 are separate structures; the outer wall of the sub-cavity 5 is provided with a slot 6, one side edge of the shoulder corner body 4 is provided with a hook 26 that cooperates with the slot 6, and the other side edge of the shoulder corner body 4 is provided with a connector 25, which cooperates with the groove 10 of the vertical frame 1.

[0108] An elastic plate 17 is provided at the opening of the U-shaped body 19 of the connector 12, and a slot 6 is provided on the outer wall of the sub-cavity 5, with the elastic plate 17 cooperating with the slot 6.

[0109] It also includes a insert 22 disposed between the vertical frames 1 and the vertical frame 1.

[0110] The first support boss 20 of the connector 12 is formed by an overlapping block 64 that overlaps the end face of the U-shaped body 19.

[0111] The first support boss 20 of the connector 12 is a roller 67, and the U-shaped body 19 is provided with a guide groove 68. The roller 67 rolls in cooperation with the guide groove 68 and the inner wall of the insertion cavity 42 of the cross frame 31.

[0112] Example 1: As Figure 1 As shown, the vertical frame 1 includes a main body 2 and a shoulder 4. The main body 2 contains a main cavity 34 and a secondary cavity 5. The side wall end face of the main cavity 34 is closed in an annular shape, and its end face is approximately convex. The side wall end of the protrusion 8 of the main cavity 34 is provided with a vertical connecting groove 36 for connecting with an external structure. The two sides of the vertical connecting groove 36 are parallel vertical groove plates 51. The side wall of the main cavity 34 is bent to form the shoulder of the main body 2. The edge of the shoulder is an inner groove 9 and a groove 10. The secondary cavity 5 is symmetrically arranged on both sides of the protrusion 8 of the main cavity 34. The outer side of the side wall of the secondary cavity 5 is provided with a first adhesive strip groove 32, which is parallel and adjacent to the vertical connecting groove 36. Shoulder corner bodies 4 are disposed on both sides of the shoulder of the vertical frame 1. The end face of the shoulder corner body 4 is folded, and a second flange 37 is provided at the fold. The two sides of the second flange 37 are vertical side edges 38 and horizontal side edges 39. The vertical side edges 38 and horizontal side edges 39 of the shoulder corner body 4 are connected to the main body 2 to form the shoulder cavity 35 of the vertical frame 1.

[0124] Example 2:

[0125] like Figure 19 , Figure 20 , Figure 21 As shown, this embodiment 2 proposes some modifications to the connector 12 based on embodiment 1. These modifications can eliminate the need for secondary processing of the first support boss 20 at the end of the second vertical plate 55 of the connector 12.

[0127] Example 3:

[0128] like Figures 23-25 As shown, this embodiment proposes some modifications to the connector 12 based on embodiment 1. These modifications can eliminate the sliding friction noise caused by thermal expansion and contraction of the cross frame 31 in the frame structure. In this embodiment, the connector 12 has a guide groove 68 at the end of the cross connecting plate 54 and a guide groove 68 at the end of the cross support plate 56. A horizontally placed roller 67 is provided at the bottom of the guide groove 68. The diameter of the roller 67 is greater than the depth of the guide groove 68. The roller 67 can be a metal cylinder.

[0130] Example 4:

[0131] like Figure 27 As shown, Embodiment 4 proposes some modifications to the vertical frame 1 based on Embodiment 1. The common sidewall of the vertical frame 1 is provided with a mating groove 29.

[0132] Example 4 proposes some modifications to the connector 12 based on Examples 1, 2, and 3. To connect with the vertical frame 1, the connector 12 is modified sequentially as follows: Figures 28-30 The structure shown is as follows. The elastic plate 17 is omitted. The inner side of the first vertical plate 13 is provided with a mating protrusion 27, and the outer side of the first vertical plate 13 is also provided with a mating locking piece 28. The connecting part 15 of the connector 12 includes the first vertical plate 13 with the mating protrusion 27 and the locking piece 28.

[0133] like Figure 31 , Figure 32 As shown, the first vertical plate 13 of the connector 12 is inserted into the secondary cavity socket 60. The side of the first vertical plate 13 with the mating protrusion 27 is vertically fitted with the side of the common side wall with the groove 10. The outer side of the first vertical plate 13 is provided with a structural fitting seam, in which a locking piece 28 is embedded. The end face of the support part 14 is laterally fitted with the cross section of the secondary cavity socket 60. The port of the second adhesive strip groove 63 of the support part 14 is connected with the port of the first adhesive strip groove 32 of the vertical frame 1. The first support boss 20 provided at the end of the second vertical plate 55 of the connector 12 is linearly contacted and slidably fitted with the side wall 45 of the insertion cavity 42 of the horizontal frame 31.

[0134] In this embodiment, the shoulder corner 4 of the vertical frame 1 is movably connected to the main body 2, but is not limited thereto. The shoulder corner 4 can be fixedly connected to the main body 2, with the vertical side 38 of the shoulder corner 4 fixedly connected to the shoulder of the main body 2, and the horizontal side 39 fixedly connected to the outer side of the common sidewall of the main body 2. When the vertical frame 1 is cut with an assembly opening, the secondary cavity insertion port 60 and the shoulder cavity 35 insertion port are cut simultaneously. The vertical side 38 of the shoulder corner 4 has a supporting edge for slidingly engaging with the end of the cavity 42 inserted into the horizontal frame 31.

[0135] In this embodiment, the vertical frame 1 is symmetrical about the left and right with its vertical connecting groove 36 as the center, and the opening planes 30 of the adhesive strip grooves on both sides are on the same plane. However, it is not limited to this. The two sides of the vertical frame 1 may be asymmetrical, and the opening planes 30 of the adhesive strip grooves on both sides may not be on the same plane.

[0136] In this embodiment, the horizontal frame 31 is symmetrical about the left and right with its horizontal connecting groove 48 as the center, and the opening 30 planes of the horizontal slots 49 provided on both sides are on the same plane. However, it is not limited to this. The two sides of the horizontal frame 31 may be asymmetrical, and the opening 30 planes of the horizontal slots 49 on both sides may not be on the same plane.

The horizontal frame 31 can also be a single-cavity body that only includes the plug-in cavity 42.

[0138] In this embodiment, the first vertical plate 13 and the support portion 14 of the connector 12 are on the same plane as the end face of the horizontal connecting plate 54, but this is not a limitation. To facilitate the processing of the assembly port, the openings of the secondary cavity insertion port 60 and the shoulder cavity 35 insertion port can be set to the same height. In this case, the height of the first vertical plate 13 and the support portion 14 is adapted to the opening height of the secondary cavity insertion port 60.

[0139] In this embodiment, when it is necessary to assemble the frame structure, the installation process includes the following steps: (1) First, fix the vertical frame 1 to the main structure 2 of the building; (2) Insert the connector 12 into the two ends of the joint cavity of the horizontal frame 31; (3) Align the two ends of the horizontal frame 31 and the connector 12 therein and install them into the assembly openings provided in the adjacent vertical frame 1; (4) Install the one-way seal at the end of the horizontal frame 31. When the vertical frame 1 needs to be vertically connected, the installation of the vertical frame 1 also includes the step of assembling the insert 22 and the two-way seal at the end of the vertical frame 1; when the vertical frame 1 needs to be angled, the installation of the vertical frame 1 also includes the step of installing the angle insert 22 at the end of the vertical frame 1. By repeating the above operations (1) to (4), the assembly of the entire frame structure can be completed.

[0140] In this embodiment, the panels are not limited to a single material; using panels with different properties as the covering layer can construct different building curtain walls, roofs, and buildings. For example, using insulated glass as the covering layer can construct glass curtain walls, glass skylights, and glass greenhouses; using power-generating panels as the covering layer can construct power-generating curtain walls and power-generating roofs.
