Description
Technical field
The present invention relates to building operations, steel girder erection field, specifically a kind of adjustable stretching device and adopt this device realize junior beam install method.
Background technology
The installation of girder steel is for building operations being a more common operation, its nothing more than be exactly by steel girder erection on two root posts, usual column top is provided with fixed head, namely be by 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 fixed head corresponding consistent with the fixing hole on girder steel, finally by bolt, fixed head and girder steel are fixed together, complete the installation of girder steel.
At present, in the process that steel girder erection especially junior beam is installed, have some problems occur, such as, column is after fixing lower end or other operations, probably occur that column tilts, although it is not very serious for tilting, greatly can affect the installation of junior beam.Because all prior correspondence of fixing hole on the installing hole on fixed head and junior beam sets, simultaneously the length of junior beam is also and distance between two heel posts adapts, so the inclination of column may cause the installing hole on fixed head can not be corresponding consistent with the fixing hole on junior beam completely, affect the installation of junior beam.In this case, conventional solution is: be first fixed therein on the column of side by one end of junior beam, then one end of a rope is fixed on the upper end of opposite side column, people stands in this rope of ground pull-up, correct the column of inclination, finally make the installing hole on fixed head corresponding consistent with the fixing hole on junior beam, complete installation.This solution is relatively traditional, operate also very simple, but efficiency is very low, the words of the inclination of column are corrected by people's pulling cord, dynamics and direction are all not easy to control, need the installing hole on fixed head just can be made corresponding consistent with the fixing hole on junior beam by repeatedly pulling or even repeatedly running back and forth, pole affects installation progress.
Summary of the invention
The invention provides a kind of adjustable stretching device and adopt this device to realize junior beam the method for installing, solve in the installation process of junior beam in the past, although the corrective operations of column is simple, but the dynamics in this process and direction are all not easy to control, cause efficiency lower, affect the problem of installation progress.
The present invention is that technical solution problem is achieved through the following technical solutions: a kind of adjustable stretching device, comprise leading screw and be socketed in the adjusting head on leading screw, the nut matched with leading screw is provided with in described adjusting head, described nut sleeve is connected on 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 sub-folder head away from one end of connector, and described adjusting head is provided with 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 is equidistantly fixed in adjusting head along leading screw direction.
Described connector is hollow cylindrical structure, is provided with two pieces of parallel arm-ties and top board, is provided with the disk be connected with leading screw between described arm-tie and top board in connector, and described leading screw is through arm-tie.
Described main folder head and sub-folder head include two pieces of parallel clamping plate, and four pieces of clamping plate are parallel to each other.
Adopt above-mentioned length adjustment device to realize a method for junior beam installation, comprise the following steps:
A, first two pieces of fixed heads are separately fixed on the column of both sides by H-shaped steel, by hanging device, junior beam are winched to fixed head place, first wherein one end of girder steel is bolted on the fixed head of corresponding side;
B, according to the distance between two heel posts, by rocking handle, regulate the distance between main folder head and sub-folder head, and make distance between main folder head and sub-folder head slightly larger than the distance between two heel posts;
C, the main folder head of this length adjustment device is first fixed therein the top of a root post, by the top of sub-folder head-clamp at another root post, shake rocking handle, makes the installing hole of junior beam align with the fixing hole on fixed head, then screw in bolt to be fixed, complete 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, have employed an adjustable stretching device to instead of original manpower and pull, because the direct stress point in adjustment process is just in column upper end, and Impact direction is clear and definite, can accomplish like this to get twice the result with half the effort in the correcting process of column, drastically increase the efficiency of whole operation, and then improve the installation progress of junior beam.
(2) adjustable stretching device of the present invention have employed screw structure, can step-less adjustment be accomplished, drastically increase the accuracy of length adjustment, the installing hole on fixed head can be easy to the fixing hole on junior beam, corresponding consistent rapidly, operation is simpler, and efficiency is also higher.
