Description
Technical field
The present invention relates to a kind of shaped steel and promote support system, the shaped steel that relates in particular to a kind of super high steel structure promotes support system and construction method thereof, is applied to construction steel structure technical field of construction.
Background technology
In super high steel structure system, type steel support structure plays a part shear wall, bears most of lateral force, for reduce the horizontal movement of structure and improve structure internal force distribute very effective.
The general work progress of existing resistance of super high-rise steel structures is: steel column is first installed, is refilled girder steel, then support is installed and becomes a complete frame system, carry out on this basis the construction of steel floor, so circulation is until top layer.
The installation of type steel support is all to carry out after steel column steel girder erection completes, and this has just brought a series of problem:
1. within type steel support is generally diagonal to the framework of girder steel and steel column composition, when lifting, be difficult to once in placely, need to have assisted by other instruments, thereby expend more man power and material.
2. while supporting installation location, difficulty is higher, and danger is larger.
3. each root supports while installation all needs independent lifting, and for super high steel structure, lifting once often needs for a long time, even if hang in batch on middle mounting platform, also needs secondary hoisting, thereby construction period is extended greatly when installation.
Summary of the invention
The present invention solves the deficiencies in the prior art, a kind of compact conformation is provided, effectively solve that type steel support construction is difficult, a difficult problem for long construction period, make shaped steel lifting support system and the construction method thereof of the super high steel structure that the fireballing advantage of Construction of Steel Structure really embodied.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of shaped steel of super high steel structure promotes support system, comprise steel column and a pair of type steel support that pair of spaced distributes, between the upper end of described steel column, be provided with girder steel, between the lower end of described steel column, be provided with lower girder steel, the top of type steel support and upper girder steel fix, the bottom of type steel support and steel column and lower girder steel fix, two type steel supports are symmetry shape and distribute, between described type steel support and upper girder steel, the two ends of supporting mutually respectively fixing, described upper steel beam bottom between type steel support and lower girder steel and steel column by being connected bracket are respectively equipped with pulley drag-line.
As preferably, between described upper girder steel and steel column, between lower girder steel and steel column, type steel support is fastened by high-strength bolt respectively with being connected between bracket, splice mutually by connecting bracket on the top of two type steel supports, and described type steel support is skewed distribution.
As preferably, in described steel column, be provided with stiffener.
Super high steel structure shaped steel promotes the construction method of support system, carries out according to the following steps:
(1), reinforce temporarily:
On working platform, type steel support is fixed with temporary fixed bolt with the girder steel being connected with Deepen Design figure according to working drawing, temporary fixed bolt conventionally adopts common large hex bolts, and then with bracing means by an integral unit of type steel support and girder steel formation;
Bracing means can adopt double flute steel and be connected securing member composition, and bracing means must have enough rigidity can meet support and girder steel assembling every technical requirements of integral lifting afterwards;
Working platform refers to ground or middle operation platform, for easy to assembly, moulding bed need to be set temporarily;
(2), girder steel lifting:
After steel column installs, the integral unit after reinforcing is lifted by crane and according to the requirement of construction drawing, girder steel is installed in the position of regulation, lifting should have professional to operate, and before lifting, must try to hang, and confirms errorlessly can carry out operation;
(3), location is installed:
After steel girder erection is complete, bracing means is removed and is carried out the fixing and lifting of next unit, during this, just can utilize pulley drag-line instrument by type steel support be connected bracket and align, substitute temporary fixed bolt with high-strength bolt also fixing, now high-strength bolt only needs just to twist, applied force square To=0.065*Pc*d;
Pc is high-strength bolt pretension; D is the diameter of bolt;
After treating that the girder steel being connected with steel column all installs, high-strength bolt is twisted eventually, twist eventually and need complete first twisting in latter 24 hours, the moment Tc=k*Pc*d now applying, k is torque coefficient, then by the edge of a wing of type steel support and bracket welding.
Girder steel is the general designation of upper girder steel and lower girder steel.
Advantage of the present invention is:
1. type steel support and girder steel are assembled into an integral unit in advance, have reduced lifting number of times, improved construction machinery efficiency.
2. type steel support simple installation, the vacant time after installing girder steel just can tentatively align support, install, and greatly shortens construction period.
3. fastening devices can repeatedly be utilized, and has significantly reduced the danger of type steel support installation exercise.
Therefore, the shaped steel of super high steel structure of the present invention promotes support system and construction method thereof, and compact conformation is relatively low to equipment requirement, improves efficiency of construction, reduces construction cost, lifting construction safety.
