Description

Technical Field

[0001] The present application relates to the technical field of prefabricated lattice beams, and in particular to a template for producing prefabricated lattice beams. Background Art

[0002] At present, due to the complex and changeable topography in some areas, the weak and uneven distribution of strata, the development of geological structures, the broken rock mass, and the abundant development of surface and groundwater. During the construction of pile foundations, it is necessary to excavate the foundation pit, which leads to steep slopes on both sides of the foundation pit, which is very easy to form adverse geological disasters such as collapse and landslide. Therefore, a large number of lattice beams are required to assemble to protect the slopes. The prefabricated lattice beam is composed of multiple unit cross beams spliced ​​in sequence, so the template for producing prefabricated lattice beams is also cross-shaped, but the prefabricated lattice beam template is usually integrated at present, so the number and arrangement of unit cross beams of the cast concrete lattice beam are also fixed, but in daily life, lattice beams with different arrangements may need to be used for protection for foundation pits with different slopes or different geology. At this time, it is necessary to produce or purchase a variety of different molds for casting different lattice beams, which increases the casting cost of the lattice beams. Utility Model Content
