Description

A kind of boiler girder lifts interim lengthening beam
Technical field
It the utility model is related to a kind of interim lengthening beam, in particular to a kind of boiler girder lift interim lengthening beam.
Background technology
When boiler girder lifts, typically individually lifted by an independent attached arm, due to part large girder Quality exceeds, and rate of load condensate exceeds 100% when causing the attached arm individually to be lifted, and generally, can all use 1 lifting of increase Machinery combine lifting.Increase the problem of 1 hoisting machinery does not increase machinery expenses still, but also to take others and apply 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.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use state figure of the present utility model.
Embodiment
To improve those skilled in the art to understanding of the present utility model, now by embodiment combination accompanying drawing further to this reality Illustrated with new.
With reference to figure 1-2, a kind of boiler girder lifts interim lengthening beam, including main beam and raker beam, the main beam Comprising one group of symmetrically arranged model, [36a support channel-section steel 1, one group of support channel-section steel 1 connect by some corresponding first Access slot steel 3 carries out assembled connection and forms entirety, and corresponding support kelly 4, institute are connected with rear side of the lower end of the support channel-section steel 1 The front side for stating support channel-section steel 1 is connected with corresponding support mounting plate 5, sets 4 corresponding spiral shells in the support mounting plate 5 respectively Keyhole;The raker beam includes one group of symmetrical tilts and is fixed in model [14a diagonal brace channel-section steel 2, the institute for supporting channel-section steel 1 State one group of diagonal brace channel-section steel 2 and carry out assembled connection formation entirety, the diagonal brace channel-section steel 2 by some corresponding second connection channel-section steels 6 The one end for not being secured to the support channel-section steel 1 is connected with corresponding diagonal brace installing plate 7, and 4 are set respectively on the diagonal brace installing plate 7 Individual corresponding bolt hole;The support mounting plate 5 and the diagonal brace installing plate 7 pass through its institute by corresponding bolt 8 respectively The bolt hole location and installation being provided with is on corresponding boiler girder 9.
One group of support channel-section steel 1 carries out assembled welding by two corresponding first connection channel-section steels 3 and forms entirety, described First connection channel-section steel 3 uses model [14a channel-section steel.One group of diagonal brace channel-section steel 2 passes through two corresponding second connection channel-section steels 6, which carry out assembled welding, forms entirety, and the second connection channel-section steel 6 uses model [14a channel-section steel.The bolt 8 be M24 × 130 high-strength bolt.
By the way that the utility model to be installed in the other end of large girder 9 temporarily, when large girder 9 lifts in place, this reality first With on new let-down to steelframe abacus, then drawn using chain block, attached arm is hung by slowly returning hook, luffing, lift It is in place that board roof hoisting is completed in the actions such as hook.
The foregoing is only preferred embodiment of the present utility model, it is all done according to present utility model application the scope of the claims it is equal Deng change and modification, it should all belong to covering scope of the present utility model.
