Abstract
The utility model discloses a position deviation correcting device for a steel roof truss of a factory building, which comprises a rolling shaft, a reinforcing steel bar and a jack. The rolling shaft is cylindrical; the rolling shaft is horizontally placed on an end surface at the top of a supporting post of the roof truss of the factory building; one end of the reinforcing steel bar is welded on a cross section at one end part of the rolling shaft; the other end of the reinforcing steel bar is suspended; and the jack is positioned at the lower part of the other end of the reinforcing steel bar. By using the position deviation correcting device, the position deviation of the steel roof truss of the factory building at the top of the post can be effectively corrected; lots of construction time is saved; and the construction quality is improved.
Description
Technical field
The utility model relates to building field, relates in particular to a kind of factory building room steelframe positional deviation correction device.
Background technology
At present, many factory buildings are arranged because insufficient height need be increased transformation; Factory building for the steel roof truss form is increased transformation, and a kind of method commonly used is the integral jacking roof method, and this method is in factory building, to build earlier to support to make up; Then on supporting member with jack jacking steel roof truss; Capital is increased then, steel roof truss is fallen back on the capital of increasing again, and removes supporting member at last; But, in the work progress of said method, when the steel roof truss that jacking is got up falls back on the capital of increasing; Drop point just deviation may occur; Therefore promptly can not fall the precalculated position on the capital, just need steel roof truss be done moving horizontally and make it to arrive the precalculated position a little, still; If do not having under the situation of horizontal support point; Be to move in the horizontal direction by steel roof truss by the perhaps very difficult active force that applies on the horizontal direction to steel roof truss, therefore, this is a problem demanding prompt solution in the engineering construction.
Summary of the invention
In order to address the above problem, the purpose of the utility model provides a kind of factory building steel roof truss positional deviation correction device, can effectively correct the skew of factory building steel roof truss position on capital.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of factory building steel roof truss positional deviation correction device; Comprise roller bearing, reinforcing bar and jack; It is cylindric that roller bearing is, and roller bearing lies in a horizontal plane on the top end of the pillar that supports steel roof truss, and an end of reinforcing bar is welded on the cross section of cylindric roller bearing end; The other end of reinforcing bar is unsettled, and jack is positioned at the bottom of the reinforcing bar other end.
Described deviation correcting device is welded on the length of one section reinforcing bar on roller bearing one end cross-sectional and the equal diameters of said roller bearing end cross-sectional.
Described deviation correcting device also is placed with at least one cylindric roller bearing on the top end of the pillar that supports steel roof truss.
Owing to adopted technique scheme, the utlity model has following superiority;
Operation is simple, and is novel, is convenient to operation, and rectifying effect is good, practices thrift the engineering time, improved construction quality.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: the 1-steel roof truss; The 2-roller bearing; The 3-reinforcing bar; The 4-jack; The 5-pillar.
The specific embodiment
In conjunction with Fig. 1,2; Described factory building steel roof truss positional deviation correction device, it comprises roller bearing 2, reinforcing bar 3 and jack 4, roller bearing 2 is cylindric; Roller bearing 2 lies in a horizontal plane on the top end of the pillar 5 that supports steel roof truss 1; One end of reinforcing bar is welded on the end cross-sectional of cylindric roller bearing 2, and the other end of reinforcing bar 3 is unsettled, and jack 4 is positioned at the bottom of reinforcing bar 3 other ends; Be welded on the length of one section reinforcing bar 3 on roller bearing 2 one end cross-sectional and the equal diameters of said roller bearing end cross-sectional; On the top end of the pillar 5 that supports steel roof truss, also be placed with at least one cylindric roller bearing 2.
During use, at first build interim support and construction operation platform, with of the connect disengagement of old factory building steel roof truss with pillar; Many large-tonnage jack of every Pin roof truss configuration place lower edge place, roof truss two ends, to specified altitude assignment, increase pillar then to predetermined altitude with many large-tonnage jack synchronization of jacking up roof trusses 1; With welding and not the roller bearing average level of welded reinforcement be placed into capital, follow roof truss to roller bearing, and be used for the weight that many large-tonnage jack of jacking roof truss all do not bear roof truss this moment; Then jack 4 is put into following (jack 4 is supported by described platform) of reinforcing bar 3 other ends, uses the other end of jack 4 jacking rods, because an end of reinforcing bar is welded on the end cross-sectional of roller bearing; Therefore, the reinforcing bar other end can drive roller bearing and rotate in the process that rises, and the roof truss above the roller bearing can move along with the rolling of roller bearing in the horizontal direction; After arrival requires the position, stop the jacking of jack, use many a bit of distances of large-tonnage jack synchronization of jacking up roof truss then; Roller bearing is taken out; Then roof truss is fallen to being put into above the pillar,, effectively corrected the factory building roof truss and supported the upper offset problem of putting of pillar through the utility model; Practice thrift a large amount of engineering times, improved construction quality.
