Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically to a steel frame support structure for an asymmetric external inclined wall. Background Technology

[0002] In building construction, walls are generally designed to be vertical, which eliminates horizontal forces and ensures good stability after construction. However, in some special cases, to pursue architectural aesthetics, walls are designed to be inclined. Inclined walls generate horizontal forces under gravity, which can easily lead to structural instability. Traditional support systems cannot effectively resist this horizontal thrust, making displacement and deformation prone to occur during construction. Construction requires specialized temporary support systems, demands high precision, is difficult to control errors, involves complex procedures, and results in low construction efficiency. Furthermore, traditional connection nodes in the support structure often fail to meet seismic requirements, making localized damage likely. In conclusion, inclined walls, due to the presence of horizontal forces, are unstable, making construction impossible and detrimental to seismic resistance. Utility Model Content

[0003] This utility model provides a steel frame support structure for an asymmetrical inclined wall to solve the technical problem in the prior art that the inclined wall is unstable and cannot be constructed due to the horizontal force, and is not conducive to earthquake resistance.

[0004] To solve the above problems, the present invention provides a steel frame support structure for an asymmetric external sloping wall, which adopts the following technical solution:

[0005] The system includes a sloping main light steel beam assembly for placing wall panels. The bottom end of the sloping main light steel beam assembly is provided with an embedded plate base for fixing its bottom. The sloping main light steel beam assembly is provided with multiple sets of connectors arranged at intervals along its sloping surface from top to bottom. Each set of connectors includes several horizontally spaced connectors. The connectors are provided with secondary beam angle steel vertically.

[0006] The connector includes a connecting part that can be pre-connected to the inclined main light steel beam assembly and a supporting part that allows the secondary beam angle steel to be placed vertically.

[0007] Furthermore, the inclined main light steel beam assembly includes a first steel beam pointing from bottom to top and distributed along its inclined surface, and multiple sets of second steel beams arranged laterally on the first steel beam. Each set of second steel beams consists of two beams symmetrically arranged on the upper and lower sides of the connecting part.

[0008] Furthermore, the connecting part of the connector is clamped between a corresponding set of second steel beams, and the connecting part is provided with an elongated waist hole for pre-connection with the second steel beam. The second steel beam is provided with a corresponding connecting hole. The elongated waist hole and the connecting hole are pre-connected by bolts and nuts.

[0009] Furthermore, the support is placed horizontally and the angle between the connecting part and the support is α, where 0° < α < 90°.

[0010] Furthermore, the thickness of the connector is not less than 8mm.

[0011] Furthermore, in each set of connectors, the distance between two adjacent connectors is no more than 1.2m.

[0012] Furthermore, the secondary beam angle steel has an I-shaped cross-section and a slenderness ratio of ≤150.

[0013] The beneficial effects of the steel frame support structure for the asymmetric inclined wall provided by this utility model are:

[0014] 1. In this utility model, the bottom of the inclined main light steel beam assembly is fixedly supported by a pre-embedded plate base, forming a rigid node with strong overall integrity. This solution systematically solves the problems of stability, construction accuracy, and economy in asymmetrical inclined wall structures through the innovative combination of "rigid welded base and adjustable connector + I-beam secondary beam", and has significant technical advantages and application value.

[0015] 2. In this utility model, the connecting parts are symmetrically clamped by the second steel beam from above and below, forming a multi-directional force system that effectively disperses eccentric loads. Furthermore, the elongated waist-shaped hole design (±20mm adjustment range) effectively compensates for construction errors and achieves dynamic leveling. The process of temporarily fixing with bolts followed by full welding for final fixation ensures both leveling flexibility and final strength. Attached Figure Description

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0027] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0028] An embodiment of the steel frame support structure for the asymmetric external inclined wall provided by this utility model:

[0029] like Figures 1 to 6 As shown,

[0030] The system includes a sloping main light steel beam assembly 1 for placing wall panels, with an embedded plate base 2 at its bottom for fixing its base. The embedded plate base 2 is positioned, and the bottom of the sloping main light steel beam assembly 1 and the embedded plate base 2 are fixedly connected by welding. The bottom of the sloping main light steel beam 1 and the embedded plate base 2 are connected by full penetration welding to ensure a rigid overall connection and avoid the loosening risk of traditional bolted connections.

[0031] The inclined main light steel beam assembly 1 is provided with multiple sets of connectors 3 arranged at intervals along its inclined surface from top to bottom. Each set of connectors 3 includes several horizontally spaced connectors, and the connectors 3 are provided with secondary beam angle steel 4 vertically.

[0032] The connector 3 includes a connector 31 that can be pre-connected to the inclined main light steel beam assembly 1 and a support 32 that allows the secondary beam angle steel 4 to be placed vertically.

[0033] In this embodiment, the inclined main light steel beam assembly 1 includes a first steel beam 11 pointing from bottom to top and distributed along its inclined surface, and multiple sets of second steel beams 12 arranged laterally on the first steel beam 11. Each set of second steel beams 12 consists of two symmetrically arranged on the upper and lower sides of the connecting part 31.

[0034] Connector 3 is symmetrically clamped by the second steel beam 12 from above and below, forming a multi-directional force system to disperse the eccentric load.

[0035] The connecting part 31 of the connector 3 is clamped between a corresponding set of second steel beams 12, and the connecting part 31 is provided with an elongated waist hole 311 for pre-connection to the second steel beams 12. The second steel beams 12 are provided with corresponding connecting holes 121. The elongated waist hole 311 and the connecting hole 121 are pre-connected by bolts and nuts. The adjustment capability of the elongated waist hole 311 can compensate for the installation deviation of the asymmetrical layout.

[0036] Specifically, bolts and nuts are used to temporarily fix the second steel beam 12 and the connecting part 31 through the elongated waist hole 311 and the connecting hole 121. The design of the elongated waist hole 311 allows for a horizontal displacement of ±20mm, enabling dynamic adjustment and accommodating construction errors. After leveling, the second steel beam 12 and the connecting part 31 can be fully welded together for fixation.

[0037] The support part 32 is placed horizontally and the included angle between the connecting part 31 and the support part 32 is α, where α is 18°.

[0038] The thickness of connector 3 is not less than 8mm.

[0039] In each group of connectors 3, the distance between two adjacent connectors 3 shall not exceed 1.2m. The distance between connectors 3 shall be ≤1.2m to ensure the support strength of the ALC plate while avoiding excessive use of steel.

[0040] Among them, the secondary beam angle steel 4 has an I-shaped cross-section and a slenderness ratio of ≤150. The I-shaped secondary beam angle steel 4 with a slenderness ratio of ≤150 can balance bending stiffness and lightweight.

[0041] In this embodiment, when installing the ALC wall panels on the support structure, the wall panels are bonded together using a special polymer mortar. A 10mm gap is left between the top and the sloping main light steel beam assembly 1, which is filled with foamed polyethylene rods and silicone weather-resistant sealant. The joint between the sloping main light steel beam assembly 1 and the wall panels is treated with a double layer: the inner layer is filled with waterproof sealant, and the outer layer is covered with fiberglass mesh (160g / ㎡) and then coated with crack-resistant mortar (thickness ≥8mm).

[0042] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0043] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
