Abstract

PURPOSE:To correct the settlement of a pillar by putting elastic members on both faces of the pillar to be corrected for settlement, force-tightening temporary brackets on their outsides, inserting receiving beams, and transmitting the actions of jacks inserted between the receiving beams and reaction bearers to the pillar. CONSTITUTION:Brackets 1 larger than the width size of a pillar 2 are force- tightened via spacers 4 to outer faces of a pillar 2 stuck with elastic members 5. Receiving beams 7 are provided on brackets 1 integrated with the pillar 2, and jacks 8 are inserted between receiving beams 7 and reaction bearers 9. Jacks 8 are operated, their actions are transmitted to the pillar 2, and the settlement of the pillar 2 is corrected. After the desired adjusting work is completed, tightening tools 6 are disassembled to prepare for reuse. Installing and disassembling works of temporary brackets 1 are simplified, the construction period is shortened, devices can be reused, and the settlement correction can be easily performed.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a construction method in which, in a building under construction, a column material that requires subsidence correction is repaired using a field jack. This relates to a method for installing a jack holder on a vehicle.

[Conventional technology]

For pillar materials under construction that require correction of the degree of settlement, conventionally, brackets were individually welded together as jack receiving members, and a jack was abutted and engaged with the brackets to achieve the desired shape. Repair work was carried out, and after the work was completed, the used sockeye bracket was separated and removed by cutting.

[Problem to be solved by the invention]

If it is necessary to correct the degree of settlement of the previous pillar material as described above, the same preparatory work as the correction work shall be carried out before and after the correction work for the purpose of welding, cutting, etc. for the installation and removal of individual Noyakki receiving brackets. Because the removal work is carried out, it takes a lot of time and labor, and there is a risk of using fire.Also, it is impossible to reuse the brackets themselves, which are installed and removed.Furthermore, the pillar materials that are to be corrected and sunken also have to be welded, cut, etc. There was an inconvenience that could not be avoided without considering the possibility that the strength of the material would deteriorate due to repeated use at high temperatures.

In addition, as mentioned above, the jaw bracket is integrated by welding means, so both the mounting body and the mounting body are limited to materials that can be welded, and non-weldable materials are required. Needless to say, it could not be used for pillars made of this material, and it was impossible to use it.

Therefore, this invention can be constructed regardless of the type of material that makes up the pillar material, eliminates the conventional work methods such as welding and cutting, and has a form that can be freely attached and detached using a delt nut fastener, eliminating the need for settlement correction. The purpose of this is to simplify the attachment and detachment of the bracket for the jack receiving part, which is in contact with the main power source of the correction work, to the pillar material to be used for the correction work, and to facilitate settlement correction.

[Means for Solving the Problem] As a means for achieving the above-mentioned object, the present invention provides an elastic member on each of at least two parallel faces at a desired position in a pillar material of a building that requires subsidence correction. A temporary bracket with a dimension larger than the contact width of the column material is installed on the outer surface of the temporary bracket, and a spacer is interposed between the inner surfaces of the temporary brackets that protrude beyond the width of the column material. Each of these is compressed so that the clamped column material can be further compressed with a plurality of bolts and nuts, and a support beam is interposed in a bracket that is integrated with the column material, and the support beam is The action of the jack interposed between the force carrier and the force carrier can be transmitted to the column material through the bracket.

[For production]

In order to fix jack receiving brackets to the pillars of a building under construction that requires subsidence correction, the fixing means is to attach each bracket that contacts at least two parallel sides of the pillar to the pillar. Tighten opposing points of the protruding parts from the contact surface with the fasteners of the gold nuts, press the column material with each bracket, integrate the bracket and the column material, and place the jack against the bracket. The basic action is to apply heavy pressure and transmit the motion received by the bracket to the column material, and the momentum received by the bracket is faithfully and reliably transmitted to the column material. Therefore, in order to achieve the purpose of maintaining and strengthening the integration without exhibiting sliding phenomena such as sliding on the joint surface between the bracket and the pillar material, the interposition of elastic members and spacers and the increase of the joint area are aimed at. be.

In the illustrations, all of the column materials (2) used are disclosed as H-shaped steel columns, but for example, box columns other than those shown in the illustrations and concrete base pillar columns are equally subject to the effects described below. It is something that can be done.

The length of the placket (1) must be equal to the contact width dimension of the pillar material (2) to which it is to be clamped, and its material is steel or wood. The basic form is a pair of two bottles so that they face each other through the material (2), but each of the two bottles may be divided into two as shown in the third figure.

Figures 1 to 4 disclose the form of a bracket (1) that has a larger contact area with respect to the column material (2). This is a special bracket (1) for the material (2) that can be used repeatedly on the regular pillar material (2).
