CN203175055U - Special lifting appliance for installation of concrete structure steel beams - Google Patents

Abstract

A special lifting appliance for installation of concrete structure steel beams belongs to the building field and is mainly suitable for situations where steel beams are installed on a concrete column on the premise without lifting points. The special lifting appliance is composed of a lifting rod, a chain block and a clamping claw, wherein one end of the lifting rod is welded with a lifting lug, the other end of the lifting rod is welded with the clamping claw, a lifting hook of the chain block is connected with a lifting lug, the lifting rod is formed by two steel channels which are welded at a 90-degree angle and is in an L shape, the clamping claw is formed by three steel channels which are welded and is of a U shape, and a locking pin is arranged on the clamping claw. When steel frames are lifted, holes reversed on concrete floor slabs are well utilized to enable the concrete floor slabs to be lifted, holes punched on floor slabs are reduced, and floor slabs can be conveniently conveyed to each floor. Furthermore, the special lifting appliance can be inserted easily in lifting and can be taken out conveniently after lifting so as to effectively save labor cost and reduce using amount of materials.

Description

The concrete structure girder steel is installed special hanger

Technical field

The utility model belongs to building field, mainly is applicable under the prerequisite that does not have suspension centre girder steel is installed on the concrete column, is specifically related to a kind of concrete structure girder steel special hanger is installed.

Background technology

Eleventh Five-Year Plan period is with fastest developing speed 5 years of Chinese soda industry, also is 5 years that stride forward steadily to soda ash power, and the industry integral level obtains substantive raising.Through the fast development in 5 years, China's soda ash production capacity reached 2,430 ten thousand tons, and soda ash output reached 2,029 ten thousand tons in 2010, had 9 tame enterprise production capacities above 1,000,000 tons; The technology of soda industry and equipment are through constantly innovation, approaching or part has reached international most advanced level, investigating the most of Sodium Carbonate Plant main body of discovery by reality is concrete structure, the support support of pipelines is steel beam structure, the method of lifting also is of all kinds, how to satisfy installation requirements, people are exploring always.The construction of pipeline steelframe is generally installed after the factory building main body construction is finished, and concrete floor does not arrange the hanger position yet, under the condition that can't satisfy lifting, job practices was in the past: method one: in suspension centre methods that arranges commonly used such as floor burrow, shortcoming: burrow use manually often at floor, the quantity that burrows is many, and is big to the quality influence of floor, repairs also relatively difficulty later on; Method two: upright man-like shelf or single-column pole on ground, use jack to install, shortcoming: install for the multilayer steelframe, and man-like shelf or the single-column pole specification used for the big steelframe of specification are also big, fall defeated also inconvenient toward every layer, need the material of usefulness also many, use manually often, influence the construction period.

Summary of the invention

The utility model provides a kind of concrete structure girder steel that special hanger is installed, and its objective is that utilizing on the floor pipeline that preformed hole is installed lifts, and can safety, finish the lifting of the special shaped steel of structure fast, efficiently.

The utility model is combined by suspension rod, jack and claw, the end welding hanger of suspension rod, and the other end welding claw of suspension rod, the suspension hook of jack connects hanger; It is L shaped that suspension rod becomes an angle of 90 degrees to be welded into by two channel-section steels;

Claw is welded into U-shaped by three channel-section steels, and claw is provided with lock pin.

Using method of the present utility model is: jack is hung down from the hole that floor is reserved, the suspension hook of jack hangs up hanger, the suspension rod of an angle of 90 degrees is walked around the corner angle of 90 degree of concrete column, with claw with hung that shaped steel blocks and made claw and shaped steel formation one with lock pin locking.

Stiffener is set on the claw, can manually adjusts the locating piece position, rigging is inserted in the shaped steel, play the effect of producing once and repeatedly utilizing.

Adopting two cover (positive and negative setting) the utility model suspenders to be hung shaped steel lifts by crane simultaneously, by regulating jack, make shaped steel be in balance, well utilize lever principle to install, save time, laborsaving, save material, reduce cost, can conveniently take out suspender after the installation, improve integral installation efficient greatly.

The utility model well utilizes the hole of reserving on the concrete floor to lift when the lifting steelframe, reduces floor and burrows, convenient every layer of transportation, and when lifting, insert easily, the lifting back is convenient takes out, effectively save cost of labor, reduced the expense of material.

The specific embodiment

Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model is combined by suspension rod 3, jack 7 and claw, the end welding hanger 5 of suspension rod 3, the other end welding claw 10 of suspension rod 3, the suspension hook of jack 7 connects hanger 5; It is L shaped that suspension rod 3 becomes an angle of 90 degrees to be welded into by two channel-section steels;

Claw 10 is welded into U-shaped by three channel-section steels, and claw 10 is provided with lock pin 6.

In order to guarantee the intensity at when lifting suspension rod lifting surface area, set up stiffener 4 in the both sides of the channel-section steel of claw 10.

Claims (1)

1. a concrete structure girder steel is installed special hanger, it is characterized in that it is combined by suspension rod, jack and claw, the end welding hanger of suspension rod, and the other end welding claw of suspension rod, the suspension hook of jack connects hanger; It is L shaped that suspension rod becomes an angle of 90 degrees to be welded into by two channel-section steels; Claw is welded into U-shaped by three channel-section steels, and claw is provided with lock pin.
