4 results about "Prefabrication" patented technology

Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. The term is used to distinguish this process from the more conventional construction practice of transporting the basic materials to the construction site where all assembly is carried out.

Prefabricated foundation assembly and splicing method thereof

InactiveCN110593301AAvoid damageQuick assemblyFoundation engineeringPrefabricationTransverse beam
The invention discloses a prefabricated foundation assembly which comprises at least two bases and a connecting transverse beam, wherein the at least two bases are arranged on the ground; the connecting transverse beam is used for connecting the adjacent bases; a steel structure module is fixedly arranged above each base; embedded screw studs are arranged at the upper top surface of each base; a connecting end plate is fixedly arranged at the bottom end part of each steel structure module; and connecting holes matched with the embedded screw studs are formed in the connecting end plate. Meanwhile, the invention also discloses a splicing method of the prefabricated foundation assembly. The bases and the connecting transverse beam are manufactured in advance in a prefabrication factory; during installation, all the bases are connected through the connecting transverse beam; and then, the steel structure module is arranged on each base. The pouring in a construction site is not needed; the fast splicing can be realized in the construction site; the construction period is shortened; and the work efficiency is improved.

Prefabricated whole filling wall and structural connection method thereof

PendingCN109487925AMeet the force requirementsWallsBuilding reinforcementsEngineeringPrefabrication
The invention provides a prefabricated whole filling wall and a structural connection method thereof. The filling wall comprises a wall body, a wall skeleton is arranged in the wall body, and is connected with a structural beam, a partition plate is arranged between the wall body and the structural beam, and sealing parts are arranged on the two sides of the partition plate. The structural connection method includes the following steps that the wall body is installed in place, and the wall skeleton of the wall body extends into pre-casting space of the structural beam; the structural beam is casted, and meanwhile an interval is reserved between the structural beam and the wall body; the partition plate is plugged into the interval; the two sides of the partition plate are sealed. The prefabricated whole filling wall and the structural connection method thereof have the advantages that an integrated prefabrication mode of the filling wall is changed, and the structural beam is separatedfrom the prefabricated filling wall through the partition plate; through the structure, force of the prefabricated wall is only transmitted to a structural beam on the lower layer, and cannot be accumulated downwards, and the stress requirement of the structure is met.
