Description

Tool type cushion block for jacking building

Technical Field

The utility model relates to a building reinforcement reforms transform the field, specifically is a building jacking uses instrument formula cushion.

Background

The jacking of buildings is an important means for increasing the floor height of the existing buildings. When jacking, the outriggers are additionally arranged on two sides of the column (or the wall), the jacks are arranged below the outriggers, and the column (or the wall) can be jacked after the bottom of the column (or the wall) is cut off. However, because the stroke of the piston of the jack is limited (usually 20cm), the jack cannot be jacked in place at one time, and the cushion blocks are alternatively stuffed at the bottoms of the piston and the column, so that the continuous jacking of the building can be ensured to reach the required height. In the construction operation, the inventor finds that the cushion blocks are mostly solid iron blocks, the self weight is large, and a large amount of labor is consumed by continuously plugging a plurality of cushion blocks; in addition, after a plurality of cushion blocks are accumulated to a certain height, instability is easily caused due to poor integrity, and engineering accidents are caused. Therefore, it is necessary to develop a tool pad with good integrity.

As a further technical scheme, the connecting nodes of the vertical rods, the cross rods and the inclined rods are connected in a welding or bolt connection mode.

As a further technical scheme, four sides of the panel are placed on horizontal rods of the step platform.

As a further technical scheme, the height of each step of the stepped support frame is slightly smaller than the piston stroke height of the jack.

As a further technical scheme, the length and the width of each step of the ladder supporting frame are larger than those of the base of the jack and the column.

As a further technical scheme, the groove is arranged in the center of the panel.

The utility model has the advantages that:

1. the tool type cushion block is formed by assembling section steel rod pieces, so that the self weight is light, and the labor intensity of workers is greatly reduced.

2. The tool type cushion block does not need to be carried back and forth, is continuously stacked and heightened, can be lifted only by horizontal pushing, and is convenient to construct.

3. The instrument formula cushion wholeness is good, and the panel recess has anti-skidding measure, can not appear wholeness unstability situation, and the security improves greatly.

Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the invention. As used herein, the singular forms "a", "an", and/or "the" are intended to include the plural forms as well, unless the invention expressly state otherwise, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof;

for convenience of description, the words "upper", "lower", "left" and "right" in the present application, if any, merely indicate correspondence with the upper, lower, left and right directions of the drawings themselves, and do not limit the structure, but merely facilitate the description of the present invention and simplify the description, rather than indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

As introduced in the background art, most of cushion blocks in the prior art are solid iron blocks, the weight is great, and a plurality of cushion blocks are continuously plugged, so that a large amount of labor is consumed; in addition, after a plurality of cushion blocks are accumulated to a certain height, instability is easily caused due to poor integrity, and engineering accidents are caused. Therefore, it is necessary to develop a tool type cushion block with good integrity, and in order to solve the above technical problems, the utility model provides a tool type cushion block for building jacking.

The utility model discloses an among the typical embodiment, as shown in FIG. 1, the whole stairstepping structure that is of instrument formula cushion for building jacking, it mainly utilizes shaped steel member to assemble, and wherein shaped steel member comprises montant, horizontal pole and down tube, and member cross sectional dimension calculates according to the load of jacking building and confirms. The connection nodes of the vertical rods, the transverse rods and the inclined rods can be connected through welding or detachably connected in a bolt mode and the like, and finally a stable support frame type stress structure is formed.

Furthermore, the height of each step of the stepped step is slightly smaller than the piston stroke height of the jack, so that the tool type cushion block can be plugged into the bottom of the column or a gap below the jack after each jacking.

Furthermore, the length and width of the step platform should ensure the base for placing the jack and the column.

Furthermore, a panel is arranged on the step platform, four sides of the panel are placed on the horizontal rod pieces of the step platform, and the concentrated force transmitted by the jack or the column can be uniformly transmitted into the tool type cushion block.
