The beneficial effects of the invention are as follows：1st, it is simple in construction, because this technology Shaped Steel foundation beam is located at roofing, it is not necessary under
The reserved tower crane hole in side, avoids envelope hole operation, does not influence the construction of secondary structure, electromechanical unit and decorator, operate
Simplicity, labour cost is reduced, save the duration；
2nd, the tower crane installed using this technology compares more common tower crane, has lacked bottom plate to the height of roofing, therefore reduce
Attached wall and standard knot, construction more simple and effective；
3rd, tower crane is substituted for steel construction from reinforced concrete structure, both having reduced tower crane will to foundation bearing capacity
Ask, saved cost again, shortened the duration, and tower crane remove after repeat and utilize, therefore for big scale of construction Commercial Complex and
Native condition condition is unfavorable for for the engineering of tower crane construction, the new direction that this technology will develop as future architecture.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：The vertical shaped steel of 1-, 2- horizontal section steels, 3- connecting plates, 4- base plates, 5- standard section of tower crane.
Embodiment
The present invention and its embodiment are described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the present invention includes vertical shaped steel 1 and is respectively perpendicular the horizontal type for being welded on the vertical left and right sides of shaped steel 1
Steel 2, left side horizontal section steel and right side horizontal section steel form cross girder steel on same straight line, vertical shaped steel 1, the left side
Horizontal section steel and right side horizontal type are two and be arranged in parallel, and the cross girder steel is connected by connecting plate 3 and roof structure beam
Connect.Base plate 4 is provided with the vertical shaped steel 1 and horizontal section steel 2 equidistant with cross girder steel center, is fixed on the base plate 4
There is standard section of tower crane 5.
To meet the execution conditions of secondary structure, electromechanical unit and decorator, while the turnover of material is not influenceed,
, it is necessary to set up derrick crane in roofing in the case of closing tower crane structure reserved opening.Due to by roofing bearing capacity
Limitation, therefore use shaped steel basis to substitute reinforced concrete foundation.The present invention is applied to big scale of construction Commercial Complex, and native condition condition is not
Constructed beneficial to tower crane, tower crane can only be placed on the project on roofing.
The concrete operations of the present invention are as follows：
1st, roofing is cleared up：, need to be clean by structural beams removing surface before tower crane construction is carried out, need to polish at out-of-flatness
It is smooth, it is ensured that together with tower crane is brought into close contact with structural beams.
2nd, basis arrangement：By the use of two of roofing tower crane position in decussate texture beam as the basis of tower crane,
Structural beams top lay Q345B H300*200*8*12 horizontal section steels and with 6 meters long Two bors d's oeuveres Q345B H300*200*8*12 types
Steel, Two bors d's oeuveres section steel beam are installed in cross, using the high-strength bolt+L20*200 angle steel perforation connecting plate of diameter 32, by the type
Steel foundation beam is tied up on structural beams top.
3rd, welding for steel structure：According to the size of standard section of tower crane, determine that standard knot is placed in the position on section steel beam top,
The mm of thickness steel plate of girder steel upper weld 20 of standard knot suspension column position, then by standard knot welding on the base mounting plate；Ensure Two bors d's oeuveres
Section steel beam connection integrity, it is ensured that section steel beam, steel plate, standard knot lattice column foundation location accurately weld afterwards.
4th, high-strength bolt is installed：Connected between shaped steel foundation beam and structural beams using high-strength bolt, the installation of high-strength bolt
An important factor for quality is control stability of foundation.High-strength bolt should since buying start strict control of quality, it is necessary to concentrate adopt
Qualified products are purchased, forbid to process privately.Safeguard measure should be taken during installation, nut uses torque spanner when installing, it is ensured that installation
It is required that.
5th, lightning protection：Lightning protection provides specification construction according to producer.And make following provisions：
1) tower crown end should fill lightning rod, and connection place should remove coating.
2) cable of Protection grounding can with the bolt connection of any main chord, and remove bolt and nut and
Coating on sleeve pipe.
3) chassis being connected with ground rivet clasp must not be used as the earthing pole of lightning protection device, it is necessary to separately be set outside foundation for tower crane
One grounding-for-lightning device.
4) earthing or grounding means should be installed by special messenger, because the difference between grounding resistance rate apparent time with local condition has very big change
High-accuracy instrument is wanted when changing, and determining resistance.
5) resistance of Protection grounding is no more than 4 ohm.
6) lightning protection is connected to the lightning arrester top on parapet of roofing top.
6th, foundation drainage and antirust treatment：Tower crane sets corresponding drainage measure, it is ensured that roofing is complete without ponding, steel member
Portion passes through antirust treatment.
The present invention is simple in construction, easy to operate, because this technology Shaped Steel foundation beam is located at roofing, it is not necessary to reserved in lower section
Tower crane hole, envelope hole operation is avoided, does not influence the construction of secondary structure, electromechanical unit and decorator, reduces labour cost,
Save the duration；The tower crane installed using this technology compares more common tower crane, has lacked bottom plate to the height of roofing, therefore reduce attached
Wall and standard knot, construction more simple and effective；Tower crane is substituted for steel construction from reinforced concrete structure, both reduces tower
Hang to ground requirement for bearing capacity, saved cost again, shortened the duration, and repeat and utilize after tower crane dismounting, therefore for big
Scale of construction Commercial Complex and native condition condition are unfavorable for for the engineering of tower crane construction, and this technology will turn into future architecture and develop
New direction.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
