A TOD covered curtain wall cross-joint structure

Abstract

The present invention relates to a TOD curtain wall cross-seam structure, comprising a support device arranged on an upper cover plate located on the outside of a structural seam, a structural plate connected to the main structure of the upper cover plate located on the inside of the structural seam at one end and slidably arranged on the upper part of the support device at the other end, the support device comprising a transverse support device, and the structural plate comprising a longitudinal structural plate, wherein the width of the structural seam is H, the width of the longitudinal structural plate is N, the width of the transverse support device is M, M≥2H+N, H≥100mm, and N≥150mm. The advantage is that the problem of fixing the horizontal position of the curtain wall is solved by the relative horizontal transverse sliding of the support device and the structural plate, so that when the width of the structural seam changes due to temperature changes, the horizontal position of the curtain wall is always unique, thereby avoiding the rupture of the curtain wall; the problem of releasing the vertical stress of the curtain wall is solved by the longitudinal sliding between the structural plate and the curtain wall uprights.

Description

Technical Field

[0001] The present invention relates to the technical field of TOD, and in particular to a TOD curtain wall spanning structure. Background Art

[0002] In TOD (transit-oriented development) projects, the space above the subway is usually used as the planning and construction base, that is, the subway cover space. Compared with traditional projects that use the land as the base, TOD projects use the roof of the subway building as the base for construction.

[0003] In TOD projects, the plane volume of the lower parking structure is relatively large. In order to avoid temperature cracks in the parking structure itself, the parking structure itself will be set with several structural seams to release the structural deformation caused by temperature changes (such as temperature increase or temperature decrease). The upper building structure is built on the upper cover plate of the lower parking structure, and generally cannot be set across the structural seam. However, due to design requirements, it is difficult to strictly design the outline of the upper building structure without crossing the seam.

[0004] In some cases, the curtain wall of the upper building structure will cross the structural seam of the lower parking lot. This structure will bring about a tricky problem, which is to ensure that the curtain wall and the main structure of the upper building structure are horizontally fixed to prevent the curtain wall from shaking horizontally; to ensure that the root of the curtain wall and the main structure can slide vertically to release stress; and to ensure that the curtain wall can isolate the different deformations of the parking lot structure on both sides of the structural seam after crossing the structural seam, so as to prevent the glass of the curtain wall from breaking due to the different deformation of the structure on both sides of the structural seam.

[0005] Therefore, no effective solution has been proposed for the problems in the related art of the curtain wall crossing the structural joint, such as the inability to fix horizontally, the difficulty in releasing vertical stress, and the cracking of the curtain wall. Summary of the invention

DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0055] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0056] like Figure 1 As shown, a TOD curtain wall spanning joint structure includes a structural plate 4 and a supporting device 5. The supporting device 5 is arranged above the upper cover plate 2 on the outer side of the structural joint 1. The first end of the structural plate 4 is connected to the main structure 3 above the upper cover plate 2 on the inner side of the structural joint 1. The second end of the structural plate 4 is laterally slidably arranged on the upper part of the supporting device 5 and is longitudinally slidably connected to the curtain wall vertical rod 6.

[0057] like Figures 2-3 As shown, the structural plate 4 includes a transverse structural plate 41 and a longitudinal structural plate 42. The first end of the transverse structural plate 41 is connected to the main structure 3 on the upper part of the upper cover plate 2 on the inner side of the structural seam 1, the second end of the transverse structural plate 41 is located on the outer side of the structural seam 1, the first end of the longitudinal structural plate 42 is fixedly connected to the second end of the transverse structural plate 41 to form an "L"-shaped structure, and the height of the longitudinal structural plate 42 is greater than the height of the transverse structural plate 41.

[0058] The support device 5 includes a transverse support device 51 and a longitudinal support device 52. The first end of the longitudinal support device 52 is fixedly connected to the second end of the transverse support device 51 to form an "L"-shaped structure, and the height of the longitudinal support device 52 is greater than that of the transverse support device 51.

[0059] The second end of the structural plate 4 is transversely slidably disposed between the transverse supporting device 51 and the longitudinal supporting device 52, wherein the longitudinal structural plate 42 of the structural plate 4 is always located between the transverse supporting device 51 and the longitudinal supporting device 52. In general, the transverse structural plate 41 of the structural plate 4 is above the transverse supporting device 51; in extreme cases, the second end of the transverse structural plate 41 of the structural plate 4 is outside the transverse supporting device 51.

[0060] Furthermore, when the second end of the structural plate 4 is slidably arranged on the supporting device 5, the upper end surface of the longitudinal structural plate 42 (the end surface of the second end) is higher than the upper end surface of the longitudinal supporting device 52 (the end surface of the second end), that is, taking the end surface of the second end of the longitudinal structural plate 42 as a horizontal plane, the end surface of the second end of the longitudinal structural plate 42 has a certain distance from the horizontal plane.

[0061] The width of the structural joint 1 is H, the width of the longitudinal structural plate 42 is N, the width of the transverse support device 51 is M, M≥2H+N, H≥100mm, N≥150mm. By setting the width of the transverse support device 51 to M, when the upper cover plate 2 outside the structural joint 1 moves horizontally, the second end of the structural plate 4 is still located at the upper part of the transverse support device 51 and will not be separated from the transverse support device 51, thereby avoiding the separation of the structural plate 4 from the support device 5, resulting in the problem of glass breakage caused by the downward vertical movement of the curtain wall upright 6.

[0062] In order to ensure that the structural plate 4 is still located on the upper part of the supporting device 5 in an extreme case, the width M of the transverse supporting device 51 is ≥ 2.5H + N. With the redundancy of 0.5H, it is ensured that the structural plate 4 will not be separated from the supporting device 5.

[0063] In order to reduce the friction force of the lateral sliding (ie, horizontal sliding) between the structural plate 4 and the supporting device 5 , a lateral sliding unit 7 is provided on the upper end surface of the supporting device 5 .

[0064] like Figure 4 As shown, the transverse sliding unit 7 includes a sliding plate 71 , the lower end surface of the sliding plate 71 is fixedly connected to the upper end surface of the transverse supporting device 51 , and the upper end surface of the sliding plate 71 is slidably connected to the lower end surface of the second end of the structural plate 4 .

[0065] Specifically, the slide plate 71 is a tetrafluoroethylene plate.

[0066] In another embodiment, if Figure 5 As shown, the transverse sliding unit 7 includes a fixed frame 72 and a plurality of rotating rods 73. The lower end surface of the fixed frame 72 is fixedly connected to the upper end surface of the transverse supporting device 51, and the plurality of rotating rods 73 are rotatably arranged inside the fixed frame 72, and the plurality of rotating rods 73 are slidably connected to the lower end surface of the second end of the structural plate 4.

[0067] The two different structures of the lateral sliding units 7 can reduce the friction between the structural plate 4 and the lateral supporting device 51, thereby facilitating relative lateral sliding (ie horizontal sliding) between the structural plate 4 and the lateral supporting device 51.

[0068] Specifically, in the first case, the support device 5 moves outward / inward along with the upper cover plate 2 outside the structural joint 1, that is, the structural plate 4 remains stationary, and the support device 5 moves outward / inward;

[0069] In the second case, the structural plate 4 moves toward the outside / inside along with the main structure 3 of the upper cover plate 2 located on the inner side of the structural joint 1, that is, the supporting device 5 remains stationary, and the structural plate 4 moves toward the inside / outside;

[0070] In the third case, the structural plate 4 moves outward / inward along with the main structure 3 of the upper cover plate 2 located on the inner side of the structural joint 1, and the supporting device 5 moves inward / outward along with the upper cover plate 2 on the outer side of the structural joint 1, that is, the structural plate 4 and the supporting device 5 move in the same / opposite direction.

[0071] Generally speaking, in the third case, the structural plate 4 and the supporting device 5 move in opposite directions. That is, when the temperature rises, the width of the structural joint 1 increases, and the structural plate 4 and the supporting device 5 move away from each other; when the temperature decreases, the width of the structural joint 1 decreases, and the structural plate 4 and the supporting device 5 move closer to each other.

[0072] In order to release the vertical pressure or longitudinal pressure of the curtain wall upright pole 6 , the TOD cover curtain wall cross-gap structure further includes a longitudinal hole 7 and a longitudinal sliding unit 8 .

[0073] like Figure 6 As shown, the longitudinal hole 7 is arranged at the first end of the curtain wall upright 6 , the longitudinal sliding unit 8 is arranged at the second end of the longitudinal structural plate 42 , and the longitudinal sliding unit 8 is connected to the longitudinal hole 7 in a longitudinal sliding manner.

[0074] Among them, the longitudinal sliding unit 8 includes a support column 81 and a sliding rod 82, the first end of the support column 81 is fixedly connected to the second end of the longitudinal structural plate 42, the middle part of the sliding rod 82 is fixedly connected to the second end of the support column 81, and the two ends of the sliding rod 82 are longitudinally slidably connected to the longitudinal hole 7.

[0075] The longitudinal sliding unit 8 and the longitudinal hole 7 not only ensure that the curtain wall uprights 6 and the structural plate 4 are horizontally fixed, that is, no horizontal displacement (lateral displacement) occurs between the curtain wall uprights 6 and the structural plate 4, but also release the vertical stress (longitudinal stress) of the curtain wall uprights 6, thereby preventing the glass of the curtain wall from being pulled or compressed and caused to break.

[0076] In another embodiment, if Figure 7 As shown, the longitudinal hole 7 is arranged at the second end of the longitudinal structural plate 42 , the longitudinal sliding unit 8 is arranged at the first end of the curtain wall upright 6 , and the longitudinal sliding unit 8 is slidably connected to the longitudinal hole 7 .

[0077] Among them, the longitudinal sliding unit 8 includes a support column 81 and a sliding rod 82, the second end of the support column 81 is fixedly connected to the first end of the curtain wall upright 6, the middle part of the sliding rod 82 is fixedly connected to the first end of the support column 81, and the two ends of the sliding rod 82 are longitudinally slidably connected to the longitudinal hole 7.

[0078] In order to further ensure that there is no relative horizontal displacement (lateral displacement) between the curtain wall uprights 6 and the structural panels 4 , the TOD cover curtain wall cross-joint structure further includes a lateral limiting unit 10 .

[0079] like Figure 8 As shown, the transverse limiting unit 10 is arranged on the upper end surface of the second end of the structural plate 4, that is, on the upper end surface of the second end of the longitudinal structural plate 42. When the curtain wall upright 6 is longitudinally slidably connected with the longitudinal structural plate 42, the transverse limiting unit 10 is located on the outer side and the inner side of the curtain wall upright 6 to limit the horizontal displacement of the curtain wall upright 6.

[0080] In this embodiment, the lateral limiting unit 10 is arranged on Figure 6 Longitudinal structural plate 4.

[0081] In another embodiment, if Fig. 9 As shown, the transverse limiting unit 10 is arranged on the upper end surface of the second end of the structural plate 4, that is, on the upper end surface of the second end of the longitudinal structural plate 42. When the curtain wall upright 6 is longitudinally slidably connected with the longitudinal structural plate 42, the transverse limiting unit 10 is located on the outer side and the inner side of the curtain wall upright 6 to limit the horizontal displacement of the curtain wall upright 6.

[0082] In this embodiment, the lateral limiting unit 10 is arranged on Figure 7 Longitudinal structural plate 4.

[0083] In the present invention, the structural plate 4 is used as a supporting conversion member, the lower end surface of the second end of the structural plate 4 slides laterally with the supporting device 5, and the upper end surface of the second end of the structural plate 4 slides longitudinally with the curtain wall upright 6, thereby solving the problem of fixation and sliding between the curtain wall upright 6 and the supporting device 5 and avoiding rupture of the curtain wall structure.

[0084] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
