Abstract

The utility model relates to a hoisting tool, and in particular relates to a small hoisting tool for dismantling and installing a steel beam under an environment of incapability of using an external hoisting device during construction of dismantling and installing a high-rise steel structure. The small hoisting tool comprises a support arm and a lifting eye, wherein the lifting eye is fixed on the inner side of the upper end of the support arm, the lower end of the support arm is fixed with a clamp matched with a joist steel main beam through a stiffening plate, the support arm is in an incline state and is fixedly connected with the stiffening plate, and a clamping opening of the clamp points at the inner side of the support arm. In a process of dismantling and installing the steel structure, the hoisting tool has the characteristics of light weight, flexibility, simpleness in regulation, convenience for carrying and transporting, can be singly used or combined for use according to the actual condition of a project, and has the advantages that the structure construction progress can be ensured and the construction task can be efficiently and perfectly completed compared with the traditional hoisting tool.

Description

Remove, install the small-sized suspender of girder steel
Technical field
The utility model relates to suspender, specifically a kind ofly removes in high-rise steel structure, in the installation, can't use under the environment of external application hanging device and can finish the small-sized suspender of dismountings, installation girder steel.
Background technology
At present, in high-rise steel structure dismounting, installation, usually utilize external application crane lifting equipment, or utilize the auxiliary hanging device of scope of operation fork truck, or utilize elevator to return the pulley lift-on/lift-off system, or utilize chain block boring lift-on/lift-off system.Utilize the external application crane lifting need to satisfy the crane operation space, and be subjected to the on-the-spot restriction in some engineering construction spaces, Construction of Steel Structure can't use crane as weight-lifting equipment, moreover executive cost also can increase greatly; Utilize scope of operation fork truck to need the floor holding capacity to satisfy the requirement of fork truck travelling load, originally just do not consider fork truck travelling load bearing capacity factor for some engineerings such as aging blocks transformation or the design of newly-built floor, it also is worthless utilizing fork truck; Utilizing elevator to return pulley lifting needs elevator to return pulley certain altitude and assigned address are arranged, and that prerequisite is the floor structure space is original just very low, and elevator returns pulley and need to punch and do suspension centre and just must destroy the superstructure floor, considers that from finished product protection this arrangement and method for construction is unworkable; Utilize chain block boring lifting to need chain block to finish construction, the chain block hanging point itself requires certain altitude and assigned address, equally also can damage the upper floor laminate.
The utility model content
The utility model is intended to solve the problem that exists in above-mentioned high-rise steel structure dismounting, the installation, and provides a kind of construction environment that is not subjected to limit, and is convenient to transportation carry the small-sized suspender of easy to operate dismounting, installation girder steel.
The technical scheme that the described problem that solves the utility model adopts is:
The small-sized suspender of a kind of dismounting, installation girder steel, comprise hold-down arm, hanger, it is inboard that described hanger is fixed on described hold-down arm upper end, a jig that mates with the I-beam section girder is fixed by stiffener in described hold-down arm lower end, and hold-down arm is tilting state and this stiffener is affixed, and it is inboard that the bayonet socket of jig points to hold-down arm.
Further, described hold-down arm is i-beam structure, is welded with the foundry goods hanger on the inboard wing listrium of I-beam section upper end, and the fixedly hole of chain block is arranged on the hanger.Described I-beam section bottom is welded and fixed with the stiffener upper face of horizontal, and stiffener lower face and jig are welded as a whole.Be welded with stiffening plate between described stiffener and the steel I-beam.
Compared with prior art, the utility model is removed in the installation process at steel structure, have characteristics light, flexible, that adjusting is simple, transportation is easy to carry, can use alone or in combination according to the engineering actual conditions, more can guarantee the structure construction progress than traditional suspender, but and high-efficiency high-quality finish construction task.
Description of drawings
Fig. 1 is the utility model example structure scheme drawing.
Fig. 2 is step 1 scheme drawing when using the inferior girder steel of the utility model dismounting.
Fig. 3 is step 2 scheme drawing when using the inferior girder steel of the utility model dismounting.
Among the figure: the 1-hold-down arm; The 2-hanger; The 3-stiffener; The 4-jig; The 5-stiffening plate; The 6-chain block; The 7-hole; The 8-girder; The 9-secondary beam; The 10-flitch; The 11-flooring.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, the small-sized suspender of this dismounting, installation girder steel is comprised of hold-down arm 1, hanger 2, stiffener 3, jig 4, stiffening plate 5, hold-down arm 1 is i-beam structure, is welded with foundry goods hanger 2 on the inboard wing listrium of I-beam section upper end, and the fixedly hole 7 of chain block 6 is arranged on the hanger 2; I-beam section bottom is welded and fixed with stiffener 3 upper faces of horizontal, and I-beam section is tilting state, and stiffener 3 lower faces and jig 4 are welded as a whole, and bayonet socket sensing hold-down arm 1 inboard of jig 4 is corresponding with hanger 2.For improving I-beam section and stiffener 3 in conjunction with old solid, between stiffener 3 and steel I-beam, be welded with stiffening plate 5.
Referring to Fig. 2, Fig. 3, application of the present utility model is to remove or install secondary beam 9 by I-shaped die girder 8.When the two ends of secondary beam 9 all connected with girder 8, the concrete steps of removing secondary beam 9 were:
One. by jig 4 this small-sized suspender is fixedly installed on the top flange plate of girder 8, eliminates the gap if jig 4 when having the gap between the flange plate, should take to increase billet, guarantee that suspender is firm.
Two. in the fixing upper end of chain block 6 of hanger 2, (or in the connection of inferior beam end privileged site welding hanger) then fastened in the end of the secondary beam 9 that is removed in the lower end, easy operation by chain block 6, the secondary beam 9 that needs are removed is removed assigned address (secondary beam 9 being positioned on the flitch 10 on the flooring 11 as shown in Figure 3).
The installation process of secondary beam 8 is just in time opposite with removing, and also is the anti-process of dismounting.
