An aerated concrete roof panel reinforced through a steel beam structure comprises an original aerated concrete roof panel body and new steel beams and further comprises a buttress supporting steel beams, a reinforcing steel plate and steel hanging rods through which the steel beams and the reinforcing steel plate are connected.The steel beams comprise steel beams A arranged on the center lines of the standard widths of a room in an old-style house and a steel beam B arranged on the buttress, the buttress is arranged on a ring beam of a joint of a longitudinal wall and a transverse wall, the steel beam B on the buttress and the buttress are connected through anchor bolts and fixed through two fastening nuts, holes are punched in the two sides of the lower flange of each steel beam A at the interval of 600 mm, the reinforcing steel plate is arranged at the bottom of the original aerated concrete roof panel body, the steel hanging rods penetrate the holes to be welded with the reinforcing steel plate in a right-angle mode, and a roof is hung up.According to the method, supporting points are added in the midspan of the aerated concrete roof panel, the span of the panel is reduced, the bearing force of the panel is improved, the method is an economical, reliable and high-actionability reinforcing method, and application prospects are wide.
Description
Technical field
The present invention relates to a kind of aero-concrete roof boarding adopts steel beam structure to reinforce and construction method.
Background technology
Twentieth century the seventies and eighties is being built a number of precast aerated concrete plate houses with masonry structure building as roof boarding in Beijing area, aerated concrete panel band structure looks for slope, install without setting sloping layer, roofing does waterproof coiled material after smearing screed-coat mortar, owing to being subject to the restriction of economic factor at that time, this roof style is adopted can greatly to reduce construction costs, under normality condition at that time, both bearing requirements had been met, also insulation requirement is met, there is saving construction material, easy construction, work efficiency advantages of higher, if but be continuing with will appear from long-term stiffness difference, the problems such as component poor durability and roof boarding integral rigidity difference, have a strong impact on the overall antidetonation of structure.
Summary of the invention
The present invention is in order to overcome disadvantage mentioned above, it is provided that a kind of aero-concrete roof boarding adopts steel beam structure to reinforce and construction method, in order to solve a series of problems affecting structural safety that aero-concrete roof boarding life-time service brings.A kind of economy, the reinforcement means that reliable, exploitativeness is strong, it is by arranging steel plate at the bottom of plate, adopt the method that roof boarding is sling by steel suspension rod that aero-concrete roof boarding is reinforced, solve the problem that former roof boarding stress ftractures, bearing capacity is low.
Technical scheme is as follows:
A kind of aero-concrete roof boarding adopts steel beam structure to reinforce, and including former aero-concrete roof boarding, newly adds girder steel, also includes the buttress of support steel beam, strengthening steel slab and connects the steel suspension rod of girder steel and strengthening steel slab.Described girder steel includes girder steel A and the girder steel B being arranged on buttress arranged at every standard width of a room in an old-style house centrage, described buttress is arranged on the collar tie beam of longitudinal cross wall junction, on described buttress, girder steel B and buttress are attached by crab-bolt and are fixed with dual-fastening nut, both sides, described girder steel A lower flange spacing 600 is punched, strengthening steel slab is set at the bottom of plate, described steel suspension rod welds through hole is at a right angle with strengthening steel slab, is sling by roofing.
Described girder steel is H profile steel；
Described buttress is Reinforced Concrete Materials；
The elongated layout of described strengthening steel slab, specification is 100 × 10mm；
Described steel suspension rod is 2 Φ 16600mm；
Described crab-bolt is M20.
Above-mentioned aero-concrete roof boarding adopts steel beam structure to reinforce and construction method, adopts following steps:
Step one: buttress is set in roof boarding relevant position according to designing requirement；
Step 2: install the girder steel B on buttress；
Step 3: install girder steel A, and adopt high-strength bolt to be attached girder steel A and the girder steel B on buttress；
Step 4: are punched in both sides, girder steel A lower flange, simultaneously the place's affixing steel plate in the relevant position of aerated concrete panel, and steel suspension rod is welded through hole is at a right angle with strengthening steel slab；
Step 5: the part that resident's family furred ceiling is destroyed is repaired.
Beneficial effect:
The most significant advantage of the present invention is in that to adopt strengthening of steel bridge aero-concrete roof boarding by arranging buttress in longitudinal cross wall junction, and mounted thereon girder steel, and by method that roof boarding is sling by steel suspension rod, the strong point is increased at aero-concrete roof boarding span centre, reduce the span of plate, improve the bearing capacity of plate.This technology short construction period, only need to register one's residence and hang steel plate strip at the bottom of installing plate, need not set temporary support, easy construction.This construction method does not remove original heat-insulation layer, waterproof layer simultaneously, decreases building waste, thus decreasing environmental pollution, has good economic benefit and environmental benefit.
