Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure building technology, specifically to prefabricated hanging panels for steel structure tie beam layers and their fixing devices. Background Technology
[0002] In the development of steel structure buildings, some new difficulties and challenges have also emerged. For example, modern buildings often enhance the aesthetics and user experience of their products through the layering and progression of waistlines. The conventional design method is to form lines by extending interior floor slabs and combining them with building wall panels or curtain walls. However, in sports buildings or auditoriums, to meet the height requirements, only tie beams are often installed on a certain floor, or large openings exist in some areas. In this case, if concrete slabs are projected from the steel beams or suspended from below to assist in achieving the architectural effect, the following problems arise due to the lack of interior floor slab ties: 1. The bonding performance between the steel structure and concrete is poor, making slippage or delamination likely; 2. Due to the complex geometry of the steel beams and columns, it is difficult for the concrete to completely fill the gaps during the pouring process; 3. The concrete will shrink and creep during the hardening process, which may lead to uneven stress distribution between the steel structure and concrete, resulting in cracks or deformation; 4. The steel structure tie beam layer is usually located at high altitudes or in complex spaces, making the concrete pouring process more difficult.
[0003] The present invention aims to solve the technical problems existing in the prior art. To this end, it proposes a prefabricated hanging plate for steel structure tie beam layer and its fixing device. Utility Model Content

The precast components and steel columns are connected by hinges, and the slots allow the precast components to move slightly left and right, which can effectively alleviate the thermal expansion and contraction effect caused by temperature changes.
[0022] Example 2
[0023] Please see Figure 1-2 Furthermore, based on Embodiment 1, the steel column 5 is used to bear the load of the precast slab 3 and support the precast slab 3. The material of the precast slab 3 can be concrete, steel structure or other composite materials that meet the requirements of building codes.
[0024] Furthermore, the support plate 7 has several pre-drilled slots 11, which can be used to adjust the installation deviation of the components.
[0025] Furthermore, stiffening ribs 8 are welded to the bottom of the support plate 7 to enhance its rigidity and stability. The specific size and quantity are determined by the designer according to the requirements. Initial fixation is achieved by screwing bolts into the bottom of the support plate 7.
[0026] Furthermore, an angle steel fastener 1 is welded to one side of the steel column 5. The angle steel fastener 1 is located above the precast hanging plate 3. The angle steel fastener 1 has a pre-drilled slot. After the bolt is screwed in, the out-of-plane stability of the precast component can be enhanced.
[0027] Furthermore, after the prefabricated hanging plates 3 on both sides of the steel column 5 are fixed, rubber 10 can be filled in the middle gap to limit and buffer the horizontal displacement of the prefabricated hanging plates 3. The connection node between the prefabricated hanging plates 3 and the steel column 5 can be a rigid connection or a hinged connection achieved by multiple connecting plates.
[0028] The working principle of this utility model is as follows: The main designers determine the size of the precast hanging plate 3, the reinforcement of the precast hanging plate 3, the size and spacing of the embedded parts required for the curtain wall, the number and diameter of the embedded threaded sleeves 2 at the end of the precast hanging plate 3, the size and thickness of the support plate 7, the number and position of the slots of the support plate 7, the size and requirements of the stiffening ribs 8, the model of the angle steel 1, and the number and position of the slots of the angle steel 1 through structural calculations. At the same time, they ensure that the size and shape of the precast hanging plate 3 meet the requirements. The embedded threaded sleeves 2 are pre-embedded at the end of the precast hanging plate 3 in strict accordance with the design. The hole positions are fixed using positioning molds to ensure that the hole diameter, hole spacing and verticality are accurate. After the prefabrication is completed, it is transported to the site. Before welding the support plate 7, the slots 11 are reserved according to the design requirements. The hole positions should be ensured with positioning molds to ensure accuracy. The support plate 7 is welded on the steel column 5. First, the surface of the steel column 5 is cleaned to ensure that there are no impurities such as rust and oil stains that affect the welding quality. The support plate 7 and the stiffening ribs 8 are accurately placed in the designated positions of the steel column 5 and initially fixed by spot welding. The level and measuring tools are used to correct its horizontality and verticality. After positioning, full welding is performed. Following welding, the weld is inspected for quality to ensure the absence of defects such as porosity and slag inclusions, guaranteeing its firmness and stability. The precast hanging plate 3 is then bolted to the support plate 7. First, the precast hanging plate 3 is hoisted to the designed position, ensuring that the pre-embedded threaded sleeve 2 at its end is precisely aligned with the slot 11 on the support plate 7. High-strength bolts are then screwed in to secure it. Angle steel 1 is welded onto the steel column 5, ensuring that the slot on the angle steel 1 is precisely aligned with the embedded threaded sleeve 2 on the precast hanging plate 3. High-strength bolts are then screwed in, and rubber 10 is used to fill the gaps, completing the securing process. Finally, the curtain wall and other exterior decoration professionals use the precast hanging plate 3 as the base material to complete the construction of the building's waistline.
