Description
Technical field
It is especially that many single foundation bolts are assembled into an entirety by one kind the present invention relates to the realm of building construction
Foundation bolt installation method.
Background technology
In steel structure base construction, it can't do without foundation bolt, the design of foundation bolt is single to be embedded in steel construction base
Among plinth.When the basic post head timesharing of construction, people's common practice is that first colligation column cap erects muscle, then installation form, so
Bolt locating rack is arranged in template by surveying setting-out afterwards, then again determined foundation bolt installed in bolt one by one
On the frame of position, the root of every foundation bolt and column cap are finally erected into muscle using bar dowel and are welded to connect, qualified after-pouring concrete.
There is following unfavorable factor in above-mentioned construction method：1st, how many steel structure bases are poured, it is necessary to make how many bolts
Locating rack, very waste of materials；2nd, when column cap erects the stirrup comparatively dense of muscle, crotch or the anchor slab (system of foundation bolt one end
Referred to as pre-buried structure) it would become hard to be put into column cap and erect in muscle, installation difficulty is quite big, accordingly, it would be desirable to look for the good workman of a little technologies to come
Operation, nevertheless, still there are problems.Such as, when foundation bolt is difficult to install, have by pulling hard sled firmly, with
The mode for damaging bar construction to complete the installation of foundation bolt reluctantly, but, it is necessary to which adjustment repeatedly, takes a lot of work and time-consuming after installation；
Some use gas cutting destruction stirrups realized the installation of foundation bolt later, but this will have a strong impact on the quality of construction；Need also
Will be bigger do over again could realize the installation of foundation bolt.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of installation method of foundation bolt, can quickly realize lower margin
The installation of bolt, can guarantee that construction quality again, construction cost be saved, so as to thoroughly solve to annoying foundation bolt always for many years
The technical problem that hardly possible is installed.
The technical solution of the present invention is to provide a kind of installation method of foundation bolt, comprises the following steps：
(1) according to the horizontal layout requirement in design drawing to foundation bolt in single basic column cap, by regulatory specifications
Foundation bolt quantity is got all the ready；
(2) two cross bolts support bars are intercepted, its length is equal with the widthwise edge length of basic column cap section, at this two
Center line is drawn on cross bolts support bar；
(3) two longitudinal bolt support bars are intercepted, its length is equal with the longitudinal edge length of basic column cap section, at this two
Center line is drawn on longitudinal bolt support bar；
(4) length of side that the foundation bolt arranged in four connecting rods, the length and drawing of the connecting rod encloses shape is intercepted
It is equal；
(5) bolt location-plate is made, the bolt equal with the foundation bolt quantity arranged in drawing is got out on its top face
Through hole, the installation site of foundation bolt of the position of these bolt holes with being arranged in drawing is identical, and plate top surface is positioned in bolt
On get basic axis sample dotting punch or depict center line；
(6) two pieces of located lateral surface plates are cut out, and gets basic axis sample dotting punch on its top face or depicts
This two pieces located lateral surface plates are symmetrically mounted on the front and rear sides that bolt positions plate top surface by center line respectively, it is ensured that
Here basic axis sample dotting punch depicts center line basic axis sample dotting punch or quarter on plate top surface is positioned with bolt
Center line is drawn to align, the height between located lateral plane plate top surface and bolt positioning plate top surface according to the thickness of nut and
The diameter of cross bolts support bar is determined, when the end face of nut is abutted on bolt location-plate bottom surface and cross bolts support bar
When on located lateral plane plate top surface, furthermore the distance between h and foundation bolt specified in drawing be installed to column cap and erect
When on muscle, the height h ' that thread segment exposes is equal；
(7) two pieces of longitudinal register surface plates are cut out, and gets basic axis sample dotting punch on its top face or depicts
This two pieces of longitudinal register surface plates are symmetrically mounted on the left and right sides that bolt positions plate top surface, it is ensured that here by center line respectively
Basic axis sample dotting punch or depict center line and bolt and position the basic axis sample dotting punch on plate top surface or depict
Center line aligns, and the height between longitudinal register plane plate top surface and bolt positioning plate top surface is by the top of located lateral surface plate
The diameter that face highly subtracts longitudinal bolt support bar is obtained；
(8) some supporting legs are cut out, and are installed on the bottom surface of bolt location-plate；
(9) thread segment of foundation bolt is inserted in bolt hole, and bolt is fixed in by two nuts and positioned
On plate, a nut is respectively set on the top surface of bolt location-plate and bottom surface, the bottom surface of thread segment and the nut of lower section are ensured herein
Bottom surface flush or the nut for just exposing lower section, other foundation bolts are also fixed on bolt location-plate in this way；
(10) two cross bolts support bars are individually positioned on two pieces of located lateral surface plates, it is ensured that drawn on its perisporium
The center line gone out and the basic axis sample dotting punch on located lateral surface plate depict center line and aligned, to cross bolts
The foundation bolt that support bar is affixed with it is welded；
(11) two longitudinal bolt support bars are individually positioned on two pieces of longitudinal register surface plates, and ensured on its perisporium
The center line drawn and the basic axis sample dotting punch on longitudinal register surface plate depict center line and aligned, to longitudinal spiral shell
The foundation bolt that bolt support bar is affixed with it is welded；
(12) four connecting rods are welded to the surrounding that foundation bolt encloses shape, this four connecting rods are located at foundation bolt
Pre-buried structure end；
(13) all foundation bolts an entirety has been assembled into just all after the completion of welding, has backed out nut and taken
Under；
(14) treat after the completion of the concreting below basic column cap, muscle is erected according to drawing requirement adjustment column cap, it is ensured that its
Height and plan-position；
(15) erected by surveying setting-out in column cap and draw the elevation location line of top layer stirrup and positioned at pre-buried at the top of muscle
The elevation location line of stirrup under most last layer below structure；
(16) the top layer stirrup of top rib portion outermost is erected according to position line colligation column cap, and itself and column cap are erected into muscle and is firmly welded
Connect, then all lower stirrups below colligation pre-buried structure, wouldn't colligation stirrup between stirrup under top layer stirrup and most last layer；
(17) the plane positioning center line of foundation bolt is drawn on top layer stirrup by surveying setting-out；
(18) the overall foundation bolt for removing step (13) is put into column cap and erected in muscle institute enclosure cavity body, it is ensured that thread segment court
On, at this moment two cross bolts support bars are ridden on top layer stirrup, ensure two cross bolts support bars and two longitudinal directions herein
The center line drawn on bolt support bar aligns with the plane positioning center line that is drawn on top layer stirrup respectively, then by two
Cross bolts support bar carries out firm colligation with top layer stirrup；
(19) the stirrup colligation that column cap erects all non-colligations in muscle is finished；
