Summary of the invention
The purpose of this invention is to provide a kind of pre-buried taper and carry joint type steel work bearing and job practices thereof, the slab form system that solves regional area does not have the technical problem of stress point, and has solved low, the slow problem of therefore bringing of progress of efficiency of construction.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
Joint type steel work bearing is carried in a kind of pre-buried taper; Comprise and be embedded in pre-buried steel part, the steel work bearing that is connected with pre-buried steel part in the body of wall and be supported in the girder steel on the steel work bearing; Said pre-buried steel part by taper carry joint coupling, high-strength screw mandrel, pre-buried seat combines; The two ends external screw thread of high-strength screw mandrel is connected with the internal thread of taper carrying joint coupling and pre-buried seat respectively, the anchor bar welding that said pre-buried seat is inner with body of wall, and the outer end of said taper carrying joint coupling is concordant with surface of wall; Said steel work bearing is a triangle trailer shape; Triangle side plate by pasting wall steel plate, horizontal supporting plate and both sides is welded, and has bolt hole on the said subsides wall steel plate, and bearing bolt passes this hole and taper carrying joint coupling is fastenedly connected.
Can be lined with the pad steel plate between the subsides wall steel plate of said bearing bolt and steel work bearing.
Said girder steel can be double flute steel or i iron.
The following of the other end of said girder steel can be supported by flitch, and perhaps, the two ends of said girder steel are supported on respectively on two steel work bearings.
The construction method step that joint type steel work bearing is carried in this pre-buried taper is following:
Carry, press the load size and confirm its location and spacing; According to the load that calculates, confirm the model of girder steel, confirm the concrete size of steel work bearing then with this, processing and fabricating steel work bearing;
The anchor bar welding that body is inner is connected the two ends external screw thread of high-strength screw mandrel respectively with the internal thread that joint coupling and pre-buried seat are carried in taper;
Install and fix the steel work bearing that has machined;
Can't prop up pad with flitch, bury corresponding pre-buried steel part underground, and the steel work bearing of fastening opposite side is installed, the two ends of girder steel are supported on respectively on two steel work bearings at other end metope;
In the said step 1, all need two-sided full weld between every block plate of said steel work bearing, the leg height equals thinner
The steel plate thickness of slab.
In the said step 1, the local thickening of the position steel plate of the bolt hole of said steel work bearing or add backing plate.
In the said step 2, the mounting method that joint coupling is carried in said taper is the size according to thickness of wall body, need adjust the length of high-strength screw mandrel ahead of time.
Compared with prior art the present invention has following characteristics and beneficial effect:
1. the present invention has changed the intensive scaffold building measure of conventional art, has solved manual work and has set up a large amount of scaffold labor intensive, and efficient is low, and progress is slow, can't have enough to meet the need the technical problem of use.
2. the present invention should carry out corresponding stressed checking computations before construction, takes all factors into consideration each item working load, arranges and respectively hangs steel support, and it is quick to have convenient site operation, and the probability of doing over again is low, the characteristics that the construction accuracy rate improves greatly.Each item assembly of the present invention, all detachable like other matching components of steel work bearing, double flute steel or i iron and taper carrying joint, doing the circulation turnover and using, saved operating expenses greatly.
3. the present invention has avoided setting up in a large number full hall scaffold in certain large nuclear-power factory experimental project, can practice thrift a large amount of manual works, shortens the floor slab construction time, accelerating construction progress, and bearing safety and stability, and steel support and girder steel are all stressed good.
4. the present invention can be widely used in the floorslab concrete construction, is specially adapted to large scale industry building and factory building.
