Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0025] see Figure 1-4 , a close-fitting ladder-type PC prestressed one-way laminated slab, including a one-way laminated slab main body, the middle of the one-way laminated slab body is high, and the surrounding area is low, and the middle area 1 adopts a fully prefabricated form, and the surrounding area 2 adopts a laminated form, And the surrounding area 2 is the superposition area reserved for gluten on-site layout, the upper transverse reinforcement 3 and the...

Abstract

The invention discloses a closely-spliced stepped PC prestress one-way laminated slab. The closely-spliced stepped PC prestress one-way laminated slab comprises a one-way laminated slab body, wherein the middle of the one-way laminated slab body is high, the periphery of the one-way laminated slab body is low, the middle area of the one-way laminated slab body is fully prefabricated, the peripheral area of the one-way laminated slab body is laminated, the peripheral area of the one-way laminated slab body is a laminated area reserved for reinforcing steel bar on-site arrangement, upper transverse reinforcing steel bars and upper longitudinal reinforcing steel bars are arranged in the middle area, lower transverse reinforcing steel bars and lower longitudinal reinforcing steel bars are arranged in the peripheral area, pipelines and a plurality of bolt lifting points are pre-buried in the middle area, and wire boxes are pre-buried in the peripheral area and connected with the pipelines. According to the closely-spliced stepped PC prestress one-way laminated slab, the middle area is fully prefabricated, the on-site cast-in-place amount is reduced by 50%, the on-site cast-in-place construction efficiency is improved, the plate middle area is fully prefabricated, a part of upper reinforcing steel bars are pre-buried and bound, the on-site reinforcing steel bar binding construction efficiency is improved, 50% of pipelines in the middle area are pre-buried in advance, the on-site water and electricity installation amount is greatly reduced, and water and electricity construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated concrete buildings, in particular to a close-fit ladder-type PC prestressed one-way laminated board. Background technique [0002] At present, due to the thin thickness of the prefabricated slabs, usually only 7 to 8mm, the conventional PC laminated panels are not strong in bending resistance, and it is easy to cause damage to the components during transportation and installation. In addition, conventional PC laminated panels use a large amount of steel due to the internal truss reinforcement. Thirdly, the upper laminated layer of the PC laminated board also needs to be bound with upper steel bars and pre-embedded with water and electricity, which increases the workload of on-site installation. Thirdly, PC boards are not closely joined together, and formwork needs to be set up later, which also brings a certain amount of work to the construction. Contents of the invention [0003] The ob...
