Description

A frame independent foundation hanger

technical field

The utility model relates to the technical field of model structure hoisting, in particular to a hanger with a frame independent foundation.

Background technique

The general structural model needs to be hoisted to the target position after the completion of fabrication. Since the structure of each model is different from the test, the hoisting device used will also affect the success of the hoisting and the test, so it is very important to adopt a hoisting method suitable for the structural model and test. The general structural model adopts a rigid base, and a lifting point is set on the rigid base for direct lifting. If the model structure uses an independent foundation, the lower part of the model cannot be equipped with a rigid base, so the method of using a rigid base for hoisting is no longer used. In addition, due to the structural scale reduction, the bearing capacity of the structural components is limited, and it is impossible to set lifting points on itself for hoisting. Therefore, it is an objective need to develop a hanger device with convenient operation, high work efficiency, stable lifting process and high safety performance.

Utility model content

The purpose of the utility model is to provide a frame independent foundation hanger to solve the above technical problems. The utility model has the advantages of simple and convenient operation, high safety performance, high work efficiency, stable lifting and low implementation cost.

In order to achieve the above object, the utility model adopts the following technical solutions:

A hanger with an independent foundation for the frame, including a steel frame, bottom square steel and channel steel; the top of the steel frame is a rectangular frame welded by four square steels, and the four vertices of the rectangular frame are welded perpendicular to the plane of the rectangular frame There are four vertically downward square steels, the bottom end of the steel frame is two parallel square steels, each welded between the ends of a pair of square steels perpendicular to the plane of the rectangular frame; the two square steel ends at the bottom of the steel frame There are several bolt holes equidistant on the steel; the bottom square steel is vertically fixed between the two square steels at the bottom of the steel frame by bolts; The lower end face of the bottom square steel.

Further, several hooks are arranged on the top rectangular frame of the steel frame.

Further, the distance from the central axis of the bottom square steel is equal to the distance from the central axis of each column of independent foundations.

Compared with the prior art, the utility model has the following technical effects:

The utility model adopts the detachable structure of the steel frame welded by the square steel and the bottom square steel and the channel steel, realizes the hoisting by setting the lifting point by itself, and can freely adjust the number of the bottom square steel according to the model structure, and the lifting process is stable and smooth. The safety performance is high; and the operation is convenient, the work efficiency is improved, the influence on the structural model in the process of dispatching and transportation is reduced, and the implementation cost is low, so it has good promotion value.

detailed description

In order to set forth the utility model more clearly, the utility model will be further described below through specific examples.

As shown in FIGS. 1 to 5 , a hanger with a frame independent foundation includes a steel frame 1 , a bottom square steel 2 and a channel steel 4 .

The top of the steel frame 1 is a rectangular frame welded by four square steels. The four apexes of the rectangular frame are respectively welded with four vertically downward square steels perpendicular to the plane of the rectangular frame. The bottom of the steel frame 1 is two The root parallel square steels are welded between the bottom ends of a pair of square steels perpendicular to the plane of the rectangular frame. The two square steels at the bottom of the steel frame 1 are equidistantly provided with a number of bolt holes; the bottom square steel 2 is vertically fixed between the two square steels at the bottom of the steel frame 1 by bolts; Bolts are installed on the lower end surfaces of the bottom square steel 2 on both sides of the bottom of the steel frame 1. Several suspension hooks are arranged on the top rectangular frame of the steel frame 1 . The central axis distance of bottom square steel 2 is equal to the central axis distance of each independent foundation.

The number of bottom square steel 2 is related to the span of the model structure. The structure of this model is a 3×3-span frame structure with 4 columns of independent foundations, so four square steels are used.

When the hanger of a frame independent foundation of the utility model is used, it comprises the following steps:

1) Arrange the two channel steels 4 at the lower part of the two bottom square steels 2 respectively and connect them with two bolts;

2) Lay the bottom square steel 2 under the prefabricated template of the independent foundation, and place the two bottom square steel 2 connected by the channel steel 4 on both sides of the bottom square steel 2 without channel steel connection;

3) After the pouring and maintenance of the concrete of the entire structure is completed, the steel frame 1 is hoisted above the bottom square steel 2 and connected by bolts;

4) Dig grooves in the soil box, the number of grooves is the same as the number of square steel 2 at the bottom of the hanger; the distance between the grooves is equal to the distance between the bottom square steel 2;

5) Carry out hoisting. When the hoisting is 50 cm above the position of the groove, loosen the bolts connecting the channel steel 4 and the bottom square steel 2, remove the channel steel 4, and then hoist it to the predetermined position, and the bottom square steel 2 will fall into the in the groove;

6) Loosen all the bolts, separate the steel frame from the bottom square steel 2, and pull out the bottom square steel 2 along the groove.

The groove width must be 10mm greater than the independent foundation width.

The above embodiments are only superior embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. All equivalent replacements or similarly designed devices made with reference to the present utility model are all within the scope of protection of the present utility model.
