Description

Technical Field

[0001] This utility model relates to the field of decoration and building materials, specifically a prefabricated UHPC panel unit partition wall. Background Technology

[0002] UHPC (Ultra-High-Performance Concrete) is an ultra-high-strength, ultra-tough, and ultra-durable high-performance concrete engineering material (UHPC curtain wall panels). Utilizing the theory of high bulk density, it is a fiber-reinforced product composed of ultrafine powder and fibers. By incorporating mineral pigments, it can exhibit a rich variety of colors. Furthermore, UHPC curtain wall panels possess strong chemical stability and corrosion resistance, as well as high sculptural flexibility. The superior performance of UHPC curtain wall panels has led to their increasing application in the architectural curtain wall field. Current UHPC curtain wall systems are generally frame-type, requiring on-site installation of vertical sections one by one. The UHPC curtain wall system uses a horizontal keel and the UHPC panels are hung one by one on the supporting beams. To ensure the water tightness of the curtain wall, sealant needs to be applied on-site between the UHPC panels. Multiple UHPC panels are combined to form the curtain wall. On-site installation is labor-intensive, and the deviation of each UHPC panel needs to be adjusted, making it difficult to control the quality. There is also a UHPC curtain wall system that uses a steel frame attached to the back for fixed installation and overall hanging. In this way, several UHPC panels are assembled with the steel frame in the factory to form a UHPC panel. The UHPC panel is then hung on-site as a whole, and then sealant is applied between each panel.

[0003] When assembling UHPC panels with the steel frame, gaps exist between adjacent sets of UHPC panels, making assembly and installation impossible. Gaps and deviations can cause the connection nodes between the panels and the steel frame, such as bolts and welds, to fail to transmit force properly. Some nodes may be overloaded, potentially leading to localized stress concentration and reducing the overall load-bearing capacity and seismic performance of the structure. Under long-term loads, uneven stress can cause nodes to loosen, panels to crack, or even fall off, affecting structural safety. Utility Model Content

[0008] Preferably, the sizes of the through holes and the screw holes are matched, and the fixing bolts pass through the through holes opened on the UHPC partition body and are screwed into the screw holes opened on the mounting base. After the mounting base and the mounting groove are connected, they are connected by multiple sets of fixing bolts.

[0009] Preferably, the fixing base includes a connecting strip, a fixing plate, a mating plate, and a mating hole. The fixing plate is screwed to the bottom of the UHPC partition body, the fixing plate is fixedly connected to the end of the fixing plate, and the mating plate is fixedly installed at the bottom of the connecting strip.

The sound-absorbing holes are regular hexagons.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model achieves forced positioning of adjacent partition wall bodies through the mortise and tenon design of the mounting base and mounting groove, avoiding misalignment and skewing caused by measurement or operation deviations during manual installation. Due to the setting of the mounting base and mounting groove, multiple UHPC partition wall bodies can form a whole, and the bearing force of each node is consistent, avoiding local stress concentration, improving the overall load-bearing capacity and seismic performance of the structure, and improving structural safety.

[0014] 2. When selecting UHPC partition walls for use in hotels and KTVs, if it is necessary to increase the sound insulation effect, sound-absorbing panels need to be installed on the surface of the UHPC partition wall. Multiple sets of sound-absorbing holes are evenly opened on the surface of the sound-absorbing panels. The material of the sound-absorbing panels themselves can reduce noise penetration by blocking sound wave transmission, while the evenly distributed sound-absorbing holes on the surface can convert high-frequency sound waves into heat energy through the principle of resonance sound absorption, thereby reducing indoor echo and external noise interference.

[0020] Please see Figure 1-4 This utility model provides a prefabricated UHPC panel unit partition wall, including a UHPC partition wall body 1, an assembly groove 31 is provided at the end of the UHPC partition wall body 1, an assembly seat 3 is fixedly provided on the side of the UHPC partition wall body 1 away from the assembly groove 31, a sound-absorbing panel 5 is fixedly provided on the surface of the UHPC partition wall body 1, and a fixing seat 4 is fixedly provided on both sides of the bottom of the UHPC partition wall body 1, and the UHPC partition wall body 1 is fixedly connected through the fixing seat 4.

[0021] Working Principle: Before fixing and installing the UHPC partition wall body 1, multiple sets of UHPC partition wall bodies 1 are first assembled to avoid gaps between adjacent sets. Specifically, the assembly method involves inserting the mounting base 3 on one set of UHPC partition wall bodies 1 into the mounting groove 31 on another set, and fixing it with bolts. The mortise and tenon design of the mounting base 3 and mounting groove 31 enables forced positioning of adjacent partition wall bodies, avoiding misalignment or tilting caused by measurement or operational deviations during manual installation. Through factory prefabrication control, the fit tolerance of the mounting base 3 and mounting groove 31 is controllable, ensuring the overall flatness of the wall surface, far superior to traditional masonry techniques. Normal assembly and installation can be achieved, preventing gap deviations from causing the connection nodes between the UHPC partition wall body 1 and the steel frame, such as bolts and welds, to fail to transmit force properly. Due to the setting of the mounting base 3 and mounting groove 31, multiple sets of UHPC partition wall bodies 1 can form a whole, with each node... The load-bearing capacity is consistent, avoiding localized stress concentration and improving the overall structural bearing capacity and seismic performance; thus enhancing structural safety. When selecting UHPC partition wall body 1 for hotels and KTVs, to enhance its sound insulation effect, sound-absorbing panels 5 need to be installed on its surface. Multiple sets of sound-absorbing holes 6 are evenly distributed on the surface of the sound-absorbing panel 5. The material of the sound-absorbing panel 5 itself can reduce noise penetration by blocking sound wave transmission, while the evenly distributed sound-absorbing holes 6 can convert high-frequency sound waves into heat energy dissipation through the principle of resonance sound absorption, reducing indoor echoes and external noise interference. For example, high-frequency human voices in KTV rooms can be effectively attenuated through the resonance absorption of the sound-absorbing holes 6, preventing noise leakage from affecting other rooms. As a high-density substrate, UHPC body can block low- and mid-frequency noise; the sound-absorbing panel 5 absorbs mid- and high-frequency noise, forming a double sound barrier of sound wave blocking and absorption, significantly improving the overall sound insulation performance. The presence of sound-absorbing holes 6 can reduce indoor sound wave reflectivity, reduce echoes and howls, making the sound clearer and fuller, and improving the user experience.
