Technical field
The present invention relates to building operations, steel girder erection field, specifically a kind of adjustable stretching device and adopt this device to realize the method that junior beam is installed.
Background technology
The installation of girder steel is a more common operation for building operations, its nothing more than be exactly with steel girder erection on two root posts, usually the column top is provided with fixed head, namely be with steel girder erection on fixed head, and fixed head is provided with installing hole, girder steel is provided with fixing hole, girder steel is sling, make the installing hole on the fixed head corresponding consistent with the fixing hole on the girder steel, by bolt fixed head and girder steel are fixed together at last, finish the installation of girder steel.
At present, in the process that steel girder erection especially junior beam is installed, have some problems and occur, such as, column is after fixing lower end or other operations, column probably occurring, is not very serious although tilt, and can greatly affect the installation of junior beam.Because the fixing hole on the installing hole on the fixed head and the junior beam all prior correspondence sets, simultaneously the length of junior beam also be and two heel posts between distance adapt, so the inclination of column may cause the installing hole on the fixed head can not be corresponding consistent with the fixing hole on the junior beam fully, affects the installation of junior beam.In this case, conventional solution is: the end with junior beam is fixed therein on the column of a side first, then an end of a rope is fixed on the upper end of opposite side column, the people draws this rope in the station on the ground, correct the column of inclination, finally make the installing hole on the fixed head corresponding consistent with the fixing hole on the junior beam, finish installation.This solution is tradition relatively, operate also very simple, but efficient is very low, correct the words of the inclination of column by people's pulling cord, dynamics and direction all are not easy control, need to just can make the installing hole on the fixed head corresponding consistent with the fixing hole on the junior beam by repeatedly spurring or even repeatedly running back and forth, the utmost point affects installation progress.
Summary of the invention
The invention provides a kind of adjustable stretching device and adopt this device to realize the method that junior beam is installed, solved in the past in the installation process of junior beam, although the corrective operations of column is simple, but the dynamics in this process and direction all are not easy control, cause efficient lower, affect the problem of installation progress.
The present invention is that the technical solution problem is achieved through the following technical solutions: a kind of adjustable stretching device, comprise leading screw and be socketed in adjusting head on the leading screw, be provided with the nut that matches with leading screw in the described adjusting head, described nut sleeve is connected on the leading screw, one end of described leading screw is connected with rocking handle, the other end of leading screw is connected with stock by connector, and described stock is provided with the sub-folder head away from an end of connector, and described adjusting head is provided with the main folder head.
Described adjusting head is hollow rectangular structure, and leading screw vertically penetrates adjusting head.
Described nut has two at least, and nut equidistantly is fixed in the adjusting head along the leading screw direction.
Described connector is the hollow cylinder body structure, is provided with two parallel arm-ties and top board in the connector, is provided with the disk that is connected with leading screw between described arm-tie and the top board, and described leading screw passes arm-tie.
Described main folder head includes two parallel clamping plate with the sub-folder head, and four clamping plate are parallel to each other.
A kind of method that adopts above-mentioned length adjustment device to realize the junior beam installation may further comprise the steps:
A, first two fixed heads are separately fixed on the column of both sides by H shape steel, by hanging device junior beam are winched to the fixed head place, the wherein end with girder steel is bolted on the fixed head of a corresponding side first;
B, according to the distance between two heel posts, by rocking handle, regulate the distance between main folder head and the sub-folder head, and make distance between main folder head and the sub-folder head be slightly larger than distance between two heel posts;
C, the main folder head of this length adjustment device is fixed therein first the top of a root post, with the top of sub-folder head-clamp at another root post, shake rocking handle, the installing hole of junior beam is alignd with fixing hole on the fixed head, then screw in bolt and be fixed, finish the installation of junior beam.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) the present invention compares the mounting method of original junior beam, adopted an adjustable stretching device to replace original manpower pulling, because the direct stress point in the adjustment process is just in the column upper end, and be subjected to force direction clear and definite, in the correcting process of column, can accomplish like this to get twice the result with half the effort, greatly improve the efficient of whole operation, and then improved the installation progress of junior beam.
(2) adjustable stretching device of the present invention has adopted screw structure, can accomplish step-less adjustment, greatly improve the accuracy of length adjustment, make installing hole on the fixed head can be easy to fixing hole on the junior beam, corresponding consistent rapidly, operate simplyr, efficient is also higher.
