Abstract
The utility model relates to a reinforcement supporting system at the top of a thick bearing platform, which comprises supporting columns, a crossbeam and a horizontal support. The reinforcement supporting system further comprises a reinforcement inclined strut and vertical horizontal reinforcement. The crossbeam is arranged at the upper part of each supporting column. The horizontal support is arranged between the two supporting columns. The reinforcement inclined strut is arranged between the two supporting columns. The vertical horizontal reinforcement is arranged on the supporting columns. The reinforcement supporting system is arranged at the top of a core tube bearing platform. The supporting columns as main forced columns adopt channel steel. A transverse horizontal support is arranged in the middle of the main forced direction in the same height as the supporting columns so as to reduce the checking computation whether the column is steady, thereby lowering the cross section of the supporting columns and saving the steel consumption. By actual examination, the reinforcement supporting system at the top of the thick bearing platform can ensure the security and quality of the engineering, save the steel products largely and reduce the cost.
Description
Technical field
The utility model relates to a kind of reinforcing steel support system, relates in particular to a kind of thick cushion cap top rebars support system.
Background technology
In the building course of super highrise building, the construction problem that first structure construction difficult problem that unit in charge of construction runs into is exactly thick cushion cap or raft plate, thick bearing platform construction ubiquity two big construction Difficulties: the calculating of the top reinforcement support system of cushion cap or raft plate and the control of the temperature difference of concrete in mass.Constantly perfect along with the continuous accumulation of domestic casting of concrete in mass experience and the performance of concrete own, the difficult problem of concrete in mass is captured substantially.In general high-building construction process, because the sole plate height is less, mostly less than 1m, the general bar dowel of discarding that all utilizes is welded into tripod, A font or herringbone support, do not check, in the past engineering at the middle and upper levels steel mesh reinforcement to support the example that is collapsed by pressure also of common occurrence temporarily.High-rise raft plate of today or the cushion cap thickness range 2～3m that is everlasting, and because the basis has design structures such as sump, elevator shaft foundation ditch also can increase the thickness of local base plate, numerical value up to 6m about, and the scale of construction is bigger.Can not satisfy the requirement of construction reliability and safety without the interim support of simple base plate top mat of checking computations, and economy is also relatively poor.
The utility model content
The purpose of this utility model provides a kind of construction cost thick cushion cap top rebars support system low, easy to use.
The utility model purpose is achieved through the following technical solutions:
A kind of thick cushion cap top rebars support system, comprise support post, crossbeam, horizontal support, also comprise reinforcing bar diagonal brace, vertical equity reinforcing bar, described crossbeam is installed in support post top, described horizontal support is installed between two support posts, described reinforcing bar diagonal brace is installed between two support posts, and the vertical equity reinforcement installation is on support post.
Described support post bottom welding column bottom steel plate.
Under the steel plate of described column bottom base plate reinforcing bar and additional bar dowel are installed.
The both sides at described support post intermediate altitude place respectively are provided with a vertical equity reinforcing bar.
Described support post top one side is provided with the vertical equity reinforcing bar.
The material of described support post is a channel-section steel.
The support post of described reinforced bar support system edges all is provided with the reinforcing bar diagonal brace, and the support post of reinforced bar support system mid portion is all established the reinforcing bar diagonal brace every a support post spacing.
The utility model is simple in structure, easy to use, and reinforcing steel support system is installed in core tube cushion cap top, and is big according to core tube cushion cap thickness, diverse characteristics, and reinforcing steel support system adopts shaped steel pillar-crossbeam support system.Support post adopts channel-section steel as the main stress pillar, transverse horizontal is set in the middle of support post height main stress direction supports, and reduces the calculated length of the stable checking computations of column, thereby has reduced the cross section of support post, has saved rolled steel dosage.The utility model can satisfy the safety that guarantees engineering, the needs of quality by practice examining, can farthest save steel again, reduces cost.
