The technical solution adopted for the present invention to solve the technical problems is: heavy door frame of a kind of HR and steel concrete temporary structure post are united a die device; It is characterized in that: the heavy door frame (1) of HR is adopted in ultra-high overweight large-span cast-in-situ reinforced concrete structured beam board position, and interim reinforced concrete post (2) is adopted in the vertical support under long-span beams pop-up post and the ater-casting; The heavy door frame of HR (1) is made up of channel-section steel joist (3), adjustable bracket (4), adjusting rod (5), door type frame (6), intertie (7); Adopt fastener type anchor ear (11) to reinforce the connection between interim reinforced concrete post (2) and the heavy door frame of HR (1).
The wide 1000mm of the heavy door frame (1) of HR,
large-diameter steel pipe is adopted in main vertical rod; Adopt intertie (7) to be connected between the heavy door frame of HR (1) with horizontal reinforcing steel pipe (8); Horizontal reinforcing steel pipe (8) adopts
steel pipe; Per 2 elongated continuous settings of step in the centre of falsework, and adopt fastener and door frame to buckle the jail; Channel-section steel joist (3) adopts No. 10 channel-section steels, places perpendicular to the beam axis, and the lumps of wood (10) is as the horizon bar that is parallel to the beam axis, and the spacing of arranging is not more than 300mm and evenly arranges, the lumps of wood (10) is gone up and directly laid template (9).
Interim reinforced concrete post (2) is provided with the high steel box column of 500mm at capital and binds as the supporting of top point load, adopts rubber tile to isolate at the bottom of capital and the beam slab, produces impact load when preventing to remove; Adopt fastener type anchor ear (11) to do the rigidity lateral restraint between interim reinforced concrete post (2) and the heavy door frame of HR (1), fastener type anchor ear (11) is by being provided with together along the vertical every 3900mm of pillar.
It is clear and definite that heavy door frame of HR and steel concrete temporary structure post are united a die device Load Transfer route; Convenient design; Be applicable to various planes and vertical structure distribution form; Can satisfy intensity, rigidity and the stability requirement of structure design, safety economy, but and Cost Optimization to the large span formwork system.
The heavy door frame of HR need meet " building operations gate-type steel pipe scaffold technical specification of security " JGJ128 related request, and steel concrete temporary structure post need meet " Code for design of concrete structures " GB50010 and " concrete structure engineering construction quality standards of acceptance " GB50204 related request.
Concrete job practices:
A, be familiar with drawing and select support for shuttering scheme, Modeling Calculation;
B, preparation of construction, the location unwrapping wire;
C, interim reinforced concrete post (2) are built, and the heavy door frame of HR (1) is set up;
D, main structure construction;
E, meet Structural Design Requirement after, bracing frame is removed.
Compared with prior art, the beneficial effect that the present invention had is: heavy door frame of HR and steel concrete temporary structure post are united a die device and had enough mechanical strengths, rigidity and stability, and be safe and reliable.The heavy door frame of HR (1) designs more science than traditional steel tube fastener support for shuttering, and physical dimension is standard more, the integral frame good reliability, and supporting capacity is big, and it is strong to set up flexibility, and efficiency of construction is high; The integral frame vertical direction is regulated required construction height through adjustable bracket (4), adjusting rod (5), regulates flexibly, fully satisfies the requirement of the cast-in-place engineering of various height, and its security performance is reliable, is to solve superelevation, overweight, the longspan structure construction as long as guarantee.Interim reinforced concrete post (2) can reduce the braced structures span, made full use of the good characteristic of concrete compression performance again, and overall performance is good, and cost is lower, has guaranteed construction safety.
