Problems solved by technology

[0005] The purpose of the present invention is to provide a ventilation channel for the complex problem of ventilation duct facilities in industrial plants, garages and other civil building structures, and the current situation that double T plates and grooved plates cannot exceed a larger span. Prestressed concrete beam slab and ventilation channel system, so as to simplify the building structure, and can realize the flexible turning of the ventilation channel, and can reduce the weight, increase the load, and achieve a larger span more economically

Embodiment 1

[0030]As shown in Figure 8, the position of the ventilation channel hole 2 opened on the rib plate of the hollow single T beam slab or multi-T box girder 1 should be in the low shear section 15 and the upper wing outside the shear zone at both ends. Below the slab compression area 16 and above the prestressed reinforcement area 17, if the prestressed tendon of the beam slab is curved tension, it should also avoid the prestressed reinforcement curved tension area 18, and set the rubber type membrane on the ventilation channel hole 2 Leave the grouting port 19 on the fetal membrane. Conventional strengthening measures can be taken for the ribs of the ventilation channel holes, including strengthening the steel ribs around the holes, thickening or increasing the concrete grade, or adding or thickening steel pipes matching the holes, so as to improve the bending resistance of the rib plane of the ventilation channel holes Ability to reinforce the weakened section of the opening. ...

Embodiment 2

[0033] Such as figure 1 As shown, on the basis of the embodiment, the grooved plate 1 is also provided with a sealing plate 4, if the hook 3 and the fastener 2, the fastener 2 fixes the hook 3 to the grooved plate 1 respectively. On the bottom surface of the two ribs, the sealing plate 4 is fixed on the hook 3 and sealed between the sealing plate 4 and the lower surfaces of the two ribs of the channel plate 1, and then the two ends of the lower sealing plate and the beam plate are sealed. Between the roof or the top of the beam slab formed by construction and the two ribs or sides. During construction, fix the fastener 2 on the embedded part on the bottom surface of the rib plate of the channel plate 1, then fix the sealing plate 4 on the bottom surface of the rib plate of the channel plate 1, and finally fix the sealing plate 4 and the channel plate 1 Seal the gap between the bottom surfaces of the ribs, and seal the two ends of the lower sealing plate or between the top of ...

Abstract

The invention relates to a large-span prestressed concrete beam plate comprising a trough plate, a rectangular beam, a sealing plate and two spaces, wherein one space is clamped by both ribs of a closed trough plate of the sealing plate, and the other space is clamped by both adjacent side surfaces or ribs of two adjacent beam plates; and rib plates of the beam plates are provided with a plurality of ventilating duct through holes. The invention also provides a ventilating channel system comprising a longitudinal ventilating channel and a horizontal ventilating channel, wherein the longitudinal ventilating channel is formed by the space clamped by both ribs of the closed trough plate of the sealing plate and the space clamped by both adjacent side surfaces or ribs of the two adjacent beam plates; and the horizontal ventilating channel is formed by respectively communicating the plurality of ventilating duct through holes which are parallelly arranged on the beam plates. The invention utilizes the space between two rib plates of the beam plates as the ventilating channels of an industrial factory building, a garage, and the like with out additionally paving the ventilating channels, facilitates construction and increases the truss raising height of a building.

Description

technical field [0001] The invention relates to a prefabricated reinforced concrete bearing member, in particular to a large-span prestressed concrete beam plate and ventilation channel system with ventilation channel holes on the ribs. Background technique [0002] Hollow single-T girder slabs and multi-T box girders are prefabricated reinforced concrete bearing members combined with slabs and beams, consisting of wide panels and narrow and high ribs. Its panel is both a transverse load-bearing structure and a compression zone for longitudinal load-bearing ribs. Therefore, the T-shaped plate has good structural mechanical properties, a clear force transmission level, and a simple geometric shape. It is a relatively economical load-bearing component that can be made into a large-span, large-coverage area. [0003] At present, long-span prestressed concrete hollow rectangular beams, multi-T box girders, and hollow single-T beam slabs have been widely used as standard concret...
