Workshop, it is delayed the installation period of sundry item, will certainly be so delayed integral construction progress.Simultaneously as using two not
With the hoisting machinery of performance, the safety coefficient of board roof hoisting is greatly reduced again and improves operation difficulty.Therefore, pass through
Arrangement, large girder concrete structure and the attached arm lifting performance of boiler steel structure are studied, is not surpassed in the attached arm lifting rate of load condensate of guarantee
On the premise of crossing 100%, design is a to be safely completed the board roof hoisting task that quality exceeds within the shorter duration
Boiler girder to lift interim lengthening beam be research purpose of the present utility model.
Utility model content
For in place of above-mentioned the shortcomings of the prior art, the utility model is that providing a kind of boiler girder lifting faces
When lengthening beam, the boiler girder lifts interim lengthening beam and can effectively solve the problem that the above-mentioned problems of the prior art.
The technical solution of the utility model is：A kind of boiler girder lifts interim lengthening beam, including main beam and diagonal brace
Beam, the main beam includes one group of symmetrically arranged model, and [36a support channel-section steel, one group of support channel-section steel pass through some
Corresponding first connection channel-section steel progress assembly connection formation is overall, and the lower end rear side for supporting channel-section steel is connected with corresponding branch
Kelly is supportted, corresponding support mounting plate is connected with front side of the support channel-section steel, 4 phases is set respectively in the support mounting plate
The bolt hole answered；The raker beam includes one group of symmetrical tilts and is fixed in model [the 14a diagonal brace groove for supporting channel-section steel
Steel, one group of diagonal brace channel-section steel carry out assembled connection by some corresponding second connection channel-section steels and form overall, the diagonal brace groove
One end that steel is not secured to the support channel-section steel is connected with corresponding diagonal brace installing plate, and 4 are set respectively on the diagonal brace installing plate
Individual corresponding bolt hole；The support mounting plate and the diagonal brace installing plate are provided with by corresponding bolt through it respectively
Bolt hole location and installation on corresponding boiler girder.
One group of support channel-section steel by two corresponding first connection channel-section steels carry out assembled welding formed it is overall, described the
One connection channel-section steel uses model [14a channel-section steel.
One group of diagonal brace channel-section steel by two corresponding second connection channel-section steels carry out assembled welding formed it is overall, described the
Two connection channel-section steels use model [14a channel-section steel.
The bolt is the high-strength bolt of M24 × 130.
The advantages of the utility model：By the way that the utility model to be installed in the large girder other end temporarily, board roof hoisting is just
During position, first on the utility model let-down to steelframe abacus, then drawn using chain block, attached arm is hung by slow
It is in place to return the action completion board roof hoisting such as hook, luffing, lift hook.It is achieved thereby that saving big machinery cost of use, improve
Efficiency of construction, shorten the activity duration；Other bid section normal constructions are not influenceed, can ensure integral construction progress；And improve
Hoisting Security coefficient.
