Abstract
The utility model is a large-sized prestressing light roof board, belongs to a component for fixing the construction, and comprises concrete sand grout layers of the current roof board, an insulating layer between the face layers, a roof board frame. The utility model is characterized in that the prestressing girders are arranged on the frames at the two sides of the board and connected with each other through the connecting rods. The prestressing girder comprises a rectangular steel pipe, blockages on the two ends of the steel pipe, a reinforcing steel bar with threads at two ends, fastening nuts on the reinforcing steel bar heads outreaching the blockages. Compared with the current roof board, the utility model has the advantage of a better portrait bending resistance, creates the condition for making and using the super long, large-breadth roof board, and doubles the length of the previous structural roof board. The utilization of the utility model can realize the positive effects of saving materials; simplify the construction and improve the construction project quality.
Description
Technical field
The utility model belongs to the member of fixed buildings, is specifically related to a kind of roof panel.
Background technology
At present, than the construction on the roof of large span, the modes of laying pre-manufactured roof plate that adopt more, prefabricated room panel in the past, generally by the concrete mortar surface layer on two sides, be clipped in the expanded material plate between the concrete pavement or be mixed with the concrete heat-insulating layer of heat insulating material particle, the steel frame is formed.Existing roof panel is subjected to the influence of factors such as its weight, intensity, economy, and breadth is all smaller, and flexural strength is lower.Thereby roof panel prefabricated, lay that recruitment is many, consumable quantity is big.Need carrier bar simultaneously, to satisfy the bulk strength on roof with more material construction roof panel.
Summary of the invention
The purpose of this utility model provides a kind of Large-scale Initial Stress Light Roof Boarding, is used for the construction of Long Span Roof, overcomes existing roof panel deficiency noted earlier.
Roof panel of the present utility model comprise existing roof panel the concrete mortar surface layer, be clipped in insulation layer, steel frame between surface layer, the improvement of being done is under the frame of vertical both sides of plate prestressed girder to be arranged, and between the prestressed girder of roof panel both sides connection rib is arranged.Prestressed girder is by rectangular steel pipe, the shutoff at rectangular steel pipe two ends, there is screw thread at two ends, and the reinforcing bar that passes from the rectangular steel pipe bottom, the fastening nut that stretches out on the outer steel bar end of shutoff is formed, and the reinforcing bar that the rectangular steel pipe of prestressed girder is tightened behind the nut pulls into the arch that makes progress a little.
The roof panel that has prestressed girder, have than existing roof panel and exceed a lot of vertical flexural strengths, for making and using the roof panel of overlength large format to create condition, under the situation of same material and size, the ratio length of the roof panel of structure in the past can double, and uses the utility model to bring the good effect of saving material, simplification construction, raising construction engineering quality.

The specific embodiment
Get cross section 140 * 90mm, the rectangular steel pipe of wall thickness 4mm, welding growth 7980mm, the rectangular frame of wide 1500mm.The long limit of frame is as the longitudinal prestressing beam 1 of roof panel, prestressed girder upside welding concrete slab frame 2, and frame is with 80 * 60mm, the rectangular steel pipe of wall thickness 4mm.With cross section 60 * 60mm, the steel pipe of wall thickness 3mm forms framework as the prestressed girder that connection rib 3 connects both sides.Rib is apart from 1300mm.Two diameter 12mm, the threaded reinforcing bar 4 in end are passed in the bottom in the rectangular tube of prestressed girder 1, and fastening nut 5 makes the prestressed girder middle part exceed two ends 5-10mm.Framework is placed on the prefabricated platform of groove that the degree of depth equals the connection rib height, waters the high-strength cement upper layer 8 of surface layer 6, cement perlite polyphenyl insulation layer 7, band steel mesh reinforcement under the high-strength cement of casting steel mesh reinforcement successively.The thick 10mm of surface layer, insulation bed thickness 130mm.After conventional health, promptly obtain Large-scale Initial Stress Light Roof Boarding of the present utility model.
