Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a UHPC lightweight composite panel component constructed using prefabricated construction methods. Background Technology

[0002] With the development of the construction industry, the requirements for the production efficiency of building components are constantly increasing. Precast components can be produced in factories in a standardized manner, without being limited by on-site construction environment and season, which can greatly improve production efficiency. As a combination of precast components and cast-in-place parts, lightweight composite slabs retain the high efficiency of precasting while ensuring overall performance through cast-in-place parts, meeting the needs of the rapid development of building industrialization. Factory production of precast components can better control the production environment, raw material quality, and production process, thereby effectively ensuring the quality stability and consistency of components. The precast part of lightweight composite slabs is made in the factory, which can ensure that its dimensional accuracy, concrete strength and other quality indicators meet the standards, providing a reliable quality guarantee for subsequent construction and use.

[0003] In announcement number CN220100341U, a UHPC lightweight composite slab component constructed using prefabricated methods is disclosed. This component includes a precast ultra-high performance concrete slab, top chord reinforcement, bottom chord reinforcement, and web reinforcement. Multiple web reinforcements are arranged in rows along the front-to-back direction. Each row of web reinforcements is connected by top and bottom chord reinforcements extending along the front-to-back direction. Multiple rows of web reinforcements are arranged sequentially along the left-to-right direction. The composite slab component also includes truss reinforcement. Within the same row of web reinforcements, the lower ends of two adjacent web reinforcements are connected by two truss reinforcements. The truss reinforcements are arranged parallel to the surface of the precast ultra-high performance concrete slab, with the two truss reinforcements located on the left and right outer sides of the web reinforcements. The lower ends of the web reinforcements and the truss reinforcements are embedded within the precast ultra-high performance concrete slab. No wire mesh is installed within the precast ultra-high performance concrete slab. This utility model ensures slab strength without wire mesh and is less prone to deformation during hoisting, belonging to the field of prefabricated construction.

[0004] The above-mentioned composite slab components have a relatively simple structure. The connection between the two sets of truss bars is not stable enough with only concrete support, and the thermal insulation effect is poor. Therefore, there is an urgent need for a UHPC lightweight composite slab component that is more firmly supported and fixed, more convenient to connect and use, and has better thermal insulation effect, and is constructed using prefabricated construction. Utility Model Content

[0005] The purpose of this utility model is to provide a UHPC lightweight composite slab component constructed using prefabricated methods, thereby solving the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a UHPC lightweight composite slab component constructed using prefabricated construction, comprising: three sets of truss reinforcement assemblies fixed to the upper end of the composite slab assembly for structural support, wherein an array of pre-embedded welded pipes are welded between the three sets of truss reinforcement assemblies.

[0007] Preferably, the composite slab assembly includes a lightweight composite slab with an internal thermal insulation layer. The upper end of the lightweight composite slab has a connecting groove for cooperating with the truss reinforcement assembly. By providing the composite slab assembly, the necessary grooves for connecting the truss reinforcement assembly are provided, and the use of the thermal insulation layer greatly enhances the thermal insulation performance of the building. The presence of the concrete pouring groove further improves the structural integrity of the device and the concrete used for pouring.

[0008] Preferably, the lightweight composite slab has five sets of concrete pouring grooves at its upper end, which are located on both sides of the truss reinforcement assembly. The number of concrete pouring grooves at the bottom of the lightweight composite slab is twice that at the upper end, providing the necessary connection conditions for concrete pouring.

[0009] Preferably, the truss reinforcement assembly includes a main support trunk. Three sets of the main support trunks are connected by a group of side support rods and diagonal support rods to form a vertical triangular support structure. The side support rods and diagonal support rods form an N-shaped support structure. The side support rods and diagonal support rods are connected to both sides of the upper set of main support trunks. By setting the truss reinforcement assembly, the device provides a support skeleton for the building, while the planar support rods provide mutual support between each set of truss reinforcement assemblies.

[0010] Preferably, an array of bottom fixing rods are welded to the outer bottom of the two sets of supporting main trunks. The bottom fixing rods and the supporting main trunks are arranged in a triangular configuration. The supporting main trunks between the two sets of truss rib assemblies are connected by an array of planar support rods, which ensures the stable support effect of the truss rib assemblies.

[0011] Preferably, the pre-embedded welded pipe has a groove for connecting the reinforcing bars inside, and the pre-embedded welded pipe has a welding groove in the middle section of the two sets of truss reinforcement components. By setting the pre-embedded welded pipe, the connection process of each set of devices is more secure and the use is more convenient.

[0012] Preferably, the array of pre-embedded welded pipes are evenly distributed on the upper ends of the two sets of bottom support trunks. The pre-embedded welded pipes are not connected to the side support rods and diagonal support rods, providing a suitable position for the installation and use of the pre-embedded welded pipes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up the composite plate assembly, while providing the necessary grooves for the connection of the truss reinforcement assembly, the use of the thermal insulation layer greatly enhances the thermal insulation performance of the building. The presence of the concrete pouring groove makes the device and the concrete structure used for pouring more robust. By setting up the truss reinforcement assembly, the device provides a supporting skeleton for the building, while the planar support rods provide mutual support between each group of truss reinforcement assemblies. By setting up the pre-embedded welded pipe, the connection process of each group of devices is more secure and easier to use. Attached Figure Description
