Description

Technical Field

[0001] The invention relates to the technical field of building components, and in particular to an embedded exterior wall panel connection structure for a steel structure transformer substation. Background Art

[0002] Prefabricated buildings can reduce the use of labor and meet the requirements of energy-saving and environmentally friendly buildings, so they have received widespread attention in the industry. A large number of building components in prefabricated buildings are processed in factories, including internal and external wall panels, stairs, prefabricated beams and columns, etc. Autoclaved Lightweight Concrete (ALC) for short. ALC board is a new type of building material with excellent performance, high degree of assembly, strong thermal insulation and sound insulation performance, and can be used as the wall material of prefabricated buildings.

[0003] However, due to the inconsistency of the stiffness of the main structure and the wall under the action of horizontal loads, the deformation of the two is difficult to coordinate, resulting in cracks or damage to the embedded exterior wall constrained by the main structure under the load; therefore, the research and development of prefabricated embedded wall connection structures that are coordinated with the deformation of the main structure is a necessary condition for the promotion and application of such systems in residential buildings and the realization of industrialized construction production. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, the present invention provides an embedded exterior wall panel connection structure for a steel structure substation, which has the advantage of satisfying the deformation coordination of the embedded exterior wall panels and columns under load.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A steel structure substation embedded exterior wall panel connection structure, used for connecting the embedded exterior wall panel and the column, and the inner and outer wall surfaces of the embedded exterior wall panel are respectively parallel to the inner and outer wall surfaces of the column; it includes two Z-shaped first connecting steel plates and two Z-shaped second connecting steel plates; the first connecting steel plates and the second connecting steel plates both have first connecting portions and second connecting portions parallel to each other; the first connecting portions of the two first connecting steel plates are respectively connected to the inner and outer wall surfaces of the embedded exterior wall panel through first fasteners; the first connecting portions of the two second connecting steel plates are respectively connected to the inner and outer wall surfaces of the column through second fasteners; the second connecting portions of the adjacent first connecting steel plates and the second connecting steel plates are connected; all the second connecting portions are located between the gaps between the embedded exterior wall panel and the column.

[0007] By adopting the above technical solution, the stiffness of the Z-shaped first connecting steel plate and the second connecting steel plate in the direction parallel to the wall surface of the embedded exterior wall panel is relatively weak, thereby ensuring the deformation coordination of the wall panel and the column within the structural plane; at the same time, the embedded exterior wall panel has sufficient out-of-plane stiffness and strength in the vertical direction to withstand the out-of-plane wind load, thereby satisfying the deformation coordination of the embedded exterior wall panel and the column under load.

[0008] Optionally, the first connecting steel plate and the second connecting steel plate both have a third connecting portion connecting the first connecting portion and the second connecting portion; the first connecting portions of the two first connecting steel plates are respectively close to the inner and outer wall surfaces of the embedded exterior wall panel; the first connecting portions of the two second connecting steel plates are respectively close to the inner and outer wall surfaces of the column; a gap is provided between the third connecting portion of the first connecting steel plate and the end surface of the embedded exterior wall panel close to the column; a gap is provided between the third connecting portion of the second connecting steel plate and the end surface of the column close to the embedded exterior wall panel.

[0009] By adopting the above technical solution, the first connecting portion is tightly attached to the inner and outer wall surfaces of the embedded exterior wall panel or the inner and outer wall surfaces of the column, and at the same time, a gap is arranged between the third connecting portion on the corresponding side and the end surfaces of the embedded exterior wall panel and the column that are close to each other. In this way, when subjected to an external force parallel to the wall direction of the embedded exterior wall panel, the first connecting steel plate and the second connecting steel plate will only deform in this force direction, and when subjected to an external force perpendicular to the embedded exterior wall panel, the first connecting steel plate and the second connecting steel plate are not easily deformed, thereby meeting the deformation coordination requirements of the embedded exterior wall panel and the column.

[0010] Optionally, the first fastener is a self-tapping bolt; a connecting steel pipe is pre-buried in the embedded exterior wall panel; both ends of the connecting steel pipe are provided with internal threads; and two of the first fasteners are respectively threadedly connected to the two ends of the connecting steel pipe.

[0011] By adopting the above technical solution, the connection strength between the first connecting steel plate and the embedded exterior wall panel can be improved through the pre-buried connecting steel pipe and self-tapping bolts, and at the same time, disassembly and assembly are convenient.

[0012] Optionally, the second fastener is a driven bolt; the second fastener is driven into the column.

[0013] By adopting the above technical solution, the second fastener is connected by nailing, which is easy to operate.

[0014] Optionally, the second connection parts of the adjacent first connecting steel plates and the second connecting steel plates are staggered and overlap horizontally in parts close to each other, and the horizontally overlapping parts are connected by a third fastener.

[0015] By adopting the above technical solution, through partial horizontal overlapping, when the embedded exterior wall panel is subjected to vertical external force, the first connecting steel plate and the second connecting steel plate are not easily separated, thereby increasing the strength of the embedded exterior wall panel connection structure in this direction.

[0016] Optionally, the third fastener is a double nut bolt.

[0017] By adopting the above technical solution, the double nut bolt is easy to operate, while keeping the extended length of the screws on both sides the same, thus avoiding the center of gravity of the third fastener being located outside the first connecting steel plate and the second connecting steel plate, thereby exerting force on the first connecting steel plate and the second connecting steel plate.

[0018] Optionally, it also includes an inner panel and an outer panel; the inner panel and the outer panel respectively cover the inner and outer openings of the gap between the embedded exterior wall panel and the column; both the inner panel and the outer panel are connected to the embedded exterior wall panel through a first fastener and to the column through a second fastener.

[0019] By adopting the above technical solution, the inner and outer panels respectively cover the inner and outer openings of the gap between the embedded exterior wall panel and the column, thereby improving the aesthetics.

[0020] Optionally, both the inner plate and the outer plate are formed with a first long hole for horizontal sliding of the first fastener and a second long hole for horizontal sliding of the second fastener.

[0021] By adopting the above technical solution, the existence of the first long hole and the second long hole meets the deformation requirements of the embedded exterior wall panel and the column parallel to the wall direction of the embedded exterior wall panel.

[0022] Optionally, a waterstop is provided between the inner wall surface of the embedded exterior wall panel and the inner wall surface of the column and the inner plate; a waterstop is provided between the outer wall surface of the embedded exterior wall panel and the outer wall surface of the column and the outer plate.

[0023] By adopting the above technical solution, the presence of the waterstop improves the waterproof ability of the connection structure.

[0024] Optionally, the gap between the embedded exterior wall panel and the column is filled with elastic adhesive material.

[0025] By adopting the above technical solution, the presence of the elastic bonding material improves the heat insulation and sound insulation capabilities of the connection structure, while not affecting the normal deformation of the connection structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is combined with Figure 1-Figure 3 The present invention is described in further detail.

[0042] Embodiment 1: Disclose a ring steel structure substation embedded external wall panel connection structure, refer to Figure 1 , used to connect the embedded exterior wall panel 20 and the column 10, and the inner and outer wall surfaces of the embedded exterior wall panel 20 are respectively parallel to the inner and outer wall surfaces of the column 10; specifically, it includes two Z-shaped first connecting steel plates 30, two Z-shaped second connecting steel plates 31, an inner plate 90 and an outer plate 80; refer to Figure 2 and Figure 3 , the first connecting steel plate 30 and the second connecting steel plate 31 each include a first connecting portion 32, a second connecting portion 34 and a third connecting portion 33; the first connecting portion 32 and the second connecting portion 34 are parallel to each other; the third connecting portion 33 is connected between the two ends of the first connecting portion 32 and the second connecting portion 34 that are close to each other and are respectively arranged perpendicular to the first connecting portion 32 and the second connecting portion 34 to form a Z shape; refer to Figure 1 The first connection parts 32 of the two first connection steel plates 30 are respectively connected to the inner and outer wall surfaces of the embedded exterior wall panel 20 through the first fasteners 60; the first connection parts 32 of the two second connection steel plates 31 are respectively connected to the inner and outer wall surfaces of the column 10 through the second fasteners 70; the second connection parts 34 of the adjacent first connection steel plates 30 and second connection steel plates 31 are connected by the third fasteners 40; all the second connection parts 34 and all the third connection parts 33 are located between the embedded exterior wall panel 20 and the column 10.

[0043] refer to Figure 1 In order to make the first connecting steel plate 30 and the second connecting steel plate 31 have a certain deformation ability in the direction parallel to the wall surface 21 of the embedded exterior wall panel 20, a gap is set between the third connecting portion 33 of the first connecting steel plate 30 and the end surface of the embedded exterior wall panel 20 close to the column 10, and a gap is set between the third connecting portion 33 of the second connecting steel plate 31 and the end surface of the column 10 close to the embedded exterior wall panel 20. In this way, when subjected to external force parallel to the wall surface 21 of the embedded exterior wall panel 20, the second connecting portion 34 of the first connecting steel plate 30 and the second connecting steel plate 31 has space to reciprocate in the direction parallel to the wall surface 21 of the embedded exterior wall panel 20, thereby meeting the deformation coordination requirements of the embedded exterior wall panel 20 and the column 10 in this direction.

[0044] refer to Figure 1 In order to make full use of the shape characteristics of the first connecting steel plate 30 and the second connecting steel plate 31 to meet the deformation coordination requirements of the embedded exterior wall panel 20 and the column 10 in the direction parallel to the wall surface 21 of the embedded exterior wall panel 20, the first connecting parts 32 of the two first connecting steel plates 30 are respectively close to the inner and outer wall surfaces of the embedded exterior wall panel 20, and the first connecting parts 32 of the two second connecting steel plates 31 are respectively close to the inner and outer wall surfaces of the column 10; such an arrangement also improves the force bearing capacity of the embedded exterior wall panel 20 in the vertical direction.

[0045] refer to Figure 1 The first fastener 60 is a self-tapping bolt; a connecting steel pipe 50 is pre-buried in the embedded exterior wall panel 20; both ends of the connecting steel pipe 50 are provided with internal threads; the two first fasteners 60 are respectively screwed with the two ends of the connecting steel pipe 50; in order to improve the strength of the connecting steel pipe 50, the length of the connecting steel pipe 50 is slightly shorter than the thickness of the embedded exterior wall panel 20; in order to prevent materials from entering the connecting steel pipe 50 when the connecting steel pipe 50 is pre-buried, plugs can be connected to the two ends of the connecting steel pipe 50, and the plugs can be removed before connecting the first fasteners 60.

[0046] refer to Figure 1The second fastener 70 is a driven bolt; the second fastener 70 is driven into the column 10; in order to facilitate the second fastener 70 to enter the column 10, a hole for the screw end of the second fastener 70 to enter is pre-opened on the column 10.

[0047] refer to Figure 1 The second connection parts 34 of the two first connecting steel plates 30 are located between the second connection parts 34 of the two second connecting steel plates 31, that is, the second connection parts 34 of the first connecting steel plates 30 and the second connection parts 34 of the second connecting steel plates 31 are staggered. At the same time, in order to facilitate the connection of the third fastener 40, the second connection parts 34 of the adjacent first connecting steel plates 30 and the second connecting steel plates 31 that are close to each other overlap horizontally, and the third fastener 40 connects the above-mentioned horizontally overlapping parts; compared with the situation where the second connection parts 34 of the adjacent first connecting steel plates 30 and the second connecting steel plates 31 are coplanar, the connection is more convenient. At the same time, when subjected to the vertical external force of the embedded exterior wall panel 20, the first connecting steel plate 30 and the second connecting steel plate 31 are not easy to separate, thereby increasing the strength of the embedded exterior wall panel connection structure in this direction. The third fastener 40 is a double-nut bolt, the double-headed screw of the third fastener 40 passes through the above-mentioned horizontal overlapping part, and then nuts are screwed on both ends. Compared with a single-headed bolt and nut, by controlling the extension amount on both sides of the third fastener 40, the center of gravity of the third fastener 40 can be located at the connecting surface where the second connecting parts 34 of the adjacent first connecting steel plates 30 and second connecting steel plates 31 abut against each other, thereby avoiding the application of force to the first connecting steel plates 30 and the second connecting steel plates 31 due to the outward shift of the center of gravity of the third fastener 40.

[0048] refer to Figure 1 The inner plate 90 is located on the inner side of the embedded exterior wall panel 20, and the outer plate 80 is located on the outer side of the embedded exterior wall panel 20. The inner plate 90 abuts against the first connection portion 32 of the first connection steel plate 30 and the second connection steel plate 31 on the corresponding side, and the outer plate 80 abuts against the first connection portion 32 of the first connection steel plate 30 and the second connection steel plate 31 on the corresponding side; in addition, both the inner plate 90 and the outer plate 80 are connected to the embedded exterior wall panel 20 through the first fastener 60 and connected to the column 10 through the second fastener 70, so that the use of fasteners is reduced, and at the same time, the first connection steel plate 30 and the second connection steel plate 31 are less likely to deform in the vertical direction of the embedded exterior wall panel 20. This arrangement allows the inner plate 90 and the outer plate 80 to respectively cover the inner and outer openings of the gap between the embedded exterior wall panel 20 and the column 10. In order to meet the deformation requirements of the embedded exterior wall panel 20 and the column 10 in a direction parallel to the wall surface 21 of the embedded exterior wall panel 20, both the inner plate 90 and the outer plate 80 are formed with a first long hole 800 for horizontal sliding of the first fastener 60 and a second long hole 801 for horizontal sliding of the second fastener 70.

[0049] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is: Figure 1 In order to enhance the waterproof property of the connection structure, a plurality of waterstop strips 100 are provided. Waterstop strips 100 are embedded between the inner plate 90 and the inner wall surface of the embedded exterior wall panel 20, between the inner plate 90 and the inner wall surface of the column 10, between the outer plate 80 and the outer wall surface of the embedded exterior wall panel 20, and between the outer plate 80 and the inner wall surface of the column 10. The waterstop strips 100 are located on the outer side of the first connecting steel plate 30 and the second connecting steel plate 31.

[0050] refer to Figure 1 In order to improve the thermal insulation and sound insulation capabilities of the connection structure, the gap between the embedded exterior wall panel 20 and the column 10 is filled with an elastic adhesive material 200, and the inner panel 90 and the outer panel 80 play a role in preventing the elastic adhesive material 200 from overflowing or falling off, wherein the material of the elastic adhesive material 200 is polyurethane or silicone adhesive; at the same time, the elastic adhesive material 200 has a certain elasticity and does not affect the normal deformation of the connection structure.

[0051] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
