Supporting and blocking installation method of beam plate type equipment foundation beam

Abstract

The invention discloses a supporting and blocking installation method of a beam plate type equipment foundation beam. After excavation of a foundation pit of a main beam construction area and a foundation pit of a secondary beam construction area is completed, a main beam cushion layer and a secondary beam cushion layer are respectively constructed in the foundation pits correspondingly, a main beam baffle control line and a secondary beam baffle control line are ejected out of the main beam cushion layer and the secondary beam cushion layer correspondingly, main beam supporting and blocking positioning holes and secondary beam supporting and blocking positioning holes are drilled at intervals along the length direction of the main beam baffle control line and the secondary beam baffle control line, main beam positioning ribs and secondary beam positioning ribs are implanted in the main beam supporting and blocking positioning holes and the secondary beam supporting and blocking positioning holes correspondingly, a main beam baffle and a secondary beam baffle are abutted to the main beam positioning ribs and the secondary beam positioning ribs correspondingly, a ground anchor is arranged in a house core soil area, steel ribs are arranged on the inner side surface of the main beam baffle and penetrates through the main beam baffle through a pull rope to be fixed to the ground anchor, the inner side and the outer side of the baffles are supported through the pull rope and positioning ribs, deformation of the baffles in a backfilling process is avoided, the construction periodis shortened, and the construction cost is also reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a support and installation method for beam-slab type equipment foundation beams. Background technique [0002] With the development of industrial buildings, the types of equipment foundations are gradually increasing and the structural forms are complex, and they are gradually becoming large-scale. Therefore, innovative equipment-based construction technologies and methods are of great significance for ensuring the quality of project construction, shortening the construction period, accelerating construction progress, saving materials, reducing labor consumption, and reducing construction costs. In the construction of plant foundations, beam-slab reinforced concrete cast-in-place structures are usually used.

Problems solved by technology

In the construction of plant foundations, beam-slab reinforced concrete cast-in-place structures are usually used. For this type of equipment foundation, the "brick membrane" forming method is usually used for construction, that is, when constructing beam-slab structure equipment foundation beams, the side of the foundation pit The earth and stone retaining is mainly made of aerated concrete brick blocks (or shale brick blocks instead), so it needs to consume a lot of block materials and mortar for masonry, and at the same time, it also requires a lot of labor. for masonry construction

Finally, after the masonry on the side of the trench is completed, the masonry mortar needs a long curing period to achieve a certain strength, resulting in the inability of the subsequent construction process to be carried out continuously

This requires more masonry materials and labor costs for masonry operations, high construction costs, and is affected by the curing time of masonry mortar, and the construction period is long
