Compression Elastic Metal Cage Mandrel

Abstract

The invention discloses a compression-resistant elastic metal net box core mold, which comprises a box base and a metal net box body. The two sides of the top of the box base are provided with pre-embedded grooves, and the inner sides of the two sets of the pre-embedded grooves are provided with mutual matching. The two sets of reinforcement plates are provided with arc-shaped adhering plates on both sides, the top of the box base is provided with grooves, and the inner side of the grooves is evenly arranged with lower core molds. The two ends of the two sides of the body are provided with side reinforcement beams that are mutually compatible with the arc-shaped cling plate and the reinforcement plate; the invention promotes the mutual cooperation of the lower core mold and the upper core mold through the splicing and combined structure of the box base and the metal mesh box body. The core mold body, and under the bonding and reinforcement of the reinforcing plate, the arc-shaped laminated plate and the side reinforcing beam, the structural strength of the main structure of the cage after the combination is effectively increased, and the concrete injected into the core mold body flows evenly, promoting The coverage and filling density of the concrete is better, and the bearing strength and deformation resistance of the lower and upper mandrels are enhanced.

Description

technical field [0001] The invention relates to the technical field of metal net box core moulds, in particular to a compression-resistant elastic metal net box core mould. Background technique [0002] In the field of construction, the application of floors is very extensive. The hollow floor is a cast-in-place reinforced concrete hollow floor, and the hollow floor is a cast-in-place reinforced concrete hollow floor, also called a cast-in-place beamless hollow floor. It is a hollow no-beam floor cast-in-place after installing the core mold product. The hollow floor is suitable for cast-in-place reinforced concrete or prestressed reinforced concrete floors, roofs, walls, foundation floors and bridges. In the process of construction, the building floor is usually filled and poured, which is also called cast-in-situ hollow floor without beam. [0003] The current floor is often built by laying metal cage mandrels, reinforcing steel tying molds and pouring concrete. However, w...

Problems solved by technology

[0003] The current floor is often built by laying metal cage mandrels, reinforcing steel molds and concrete pouring. However, in the actual application of metal cages, since the box mandrel has a hollow structure and is filled with lightweight materials, As a result, the load-bearing capacity of the column structure of the mandrel is poor, and the gaps in the steel mesh are large, which is prone to grout leakage, which leads to the misalignment of the metal cage during pouring, and the overall strength of the poured floor is too low, making it difficult to achieve Ideal requirements, during the assembly and pouring of metal cages, construction personnel often step on and move on the surface of the cages, thereby generating strong impact and pressure on the cages and mandrel, thus making the cages prone to deformation and structural damage possible, reduce the seismic force of the mandrel, increase the follow-up maintenance process, and reduce the construction efficiency of floor pouring; Out of the net cage, it will cause damage to the main structure of the net cage, reduce the accuracy of mandrel pouring, and affect the structural strength and service life of the metal net cage
