Description

Fixing device for throwing support

Technical Field

The utility model relates to the field of building construction, in particular to a fixing device for throwing and supporting.

Background

The polishing and supporting architecture expression is a rod piece which is obliquely crossed with the outer side surface of the scaffold. Throwing support is also called support. Commonly known as pressing the fence. The inclined rods are arranged around the scaffold to transversely support the scaffold, and form an included angle of about 60 degrees with the ground.

At present, the installation mode of the throwing support generally adopts direct abutting on the ground, and the top of the throwing support is connected with the outer side face of the scaffold through a fastener. However, the supporting mode has certain requirements on the flatness of the ground, so that a worker needs to level the position of the support in advance when the support is installed, and the construction time is increased; and the polishing support and the ground are used for carrying out oblique support by virtue of friction force, so that the effect of providing support is not ideal.

The utility model provides a fixing device for throwing and supporting, which adopts the following technical scheme:

the utility model provides a throw and prop with fixing device, includes dead lever and connecting rod, the connecting rod sets up in the top of dead lever, the bottom normal running fit of dead lever is provided with two at least and goes up the inserted bar, and is adjacent normal running fit is provided with connecting portion between the last inserted bar, but connecting rod drive connecting portion along axial displacement makes upward the inserted bar outwards expand or inwards contract, the dead lever passes to throw the fixed part that props and inserts in the soil and to throw the formation fixedly.

Optionally, a screw is fixedly arranged at the bottom of the connecting rod, and the screw penetrates through the fixing rod to be in threaded connection with the connecting part.

Optionally, the connecting rod is provided with a perforation.

Optionally, the bottom of going up the inserted bar articulates there is lower inserted bar, lower inserted bar articulates with connecting portion.

Optionally, the upper insert rod includes a first upper insert rod and a second upper insert rod, the lower insert rod includes a first lower insert rod and a second lower insert rod, and the cross section of the first upper insert rod, the second upper insert rod, the first lower insert rod and the second lower insert rod after expansion is approximately rectangular.

In summary, the present utility model includes at least one of the following beneficial technical effects: the fixing device designed by the utility model can be repeatedly used, is firm in connection, simple and practical, and is wide in application, convenient to use, safe and reliable.

Detailed Description

The utility model is described in further detail below with reference to fig. 1-2.

The embodiment of the utility model discloses a fixing device for throwing and supporting.

Referring to fig. 1 and 2, a fixing device for throwing and supporting includes a fixing rod 6 and a connecting rod 9, the connecting rod 9 is disposed at the top of the fixing rod 6, at least two upper inserting rods are disposed at the bottom of the fixing rod 6 in a rotating fit manner, a connecting portion 5 is disposed between adjacent upper inserting rods in a rotating fit manner, the connecting rod 9 can drive the connecting portion 5 to axially move so that the upper inserting rods expand outwards or shrink inwards, and the fixing rod 6 penetrates through the fixing portion of the throwing and supporting to be inserted into soil and fixed to the throwing and supporting. The fixing device designed by the utility model can be repeatedly used, is firm in connection, simple and practical, is widely applicable, is convenient to use, and is safe and reliable.

In the embodiment, one end of the throwing support, which is in contact with the ground, is provided with a fixing part, a through hole 8 for a connecting rod 9 to pass through is formed in the fixing part, and the throwing support is fixed through a fixing device, so that the throwing support is convenient to use, safe and reliable.

In this embodiment, the bottom of the connecting rod 9 is fixedly provided with a screw 7, and the screw 7 passes through the fixing rod 6 to be screwed with the connecting portion 5.

The connecting rod 9 has offered perforation 8 along the horizontal direction, and perforation 8 supplies appurtenance to insert, in the steel pipe inserted perforation 8 for example, has increased the power arm, rotates more laborsaving.

The bottom of going up the inserted bar articulates there is lower inserted bar, and lower inserted bar articulates with connecting portion 5, connecting portion 5 and screw rod 7 threaded connection, screw rod 7 and dead lever 6 fixed connection, and dead lever 6 rotation in-process, screw rod 7 follow dead lever 6 and rotate, order about connecting portion 5 along screw rod 7 axial reciprocates to make and go up inserted bar and lower inserted bar expansion or shrink.

In this embodiment, go up the inserted bar and go up the inserted bar including first inserted bar and second, first inserted bar and second go up the inserted bar and articulate respectively in the bottom of dead lever 6, lower inserted bar includes first inserted bar and second lower inserted bar, first inserted bar and second lower inserted bar respectively with first inserted bar and second go up the inserted bar articulated, first inserted bar, second go up the inserted bar, first inserted bar and second lower inserted bar expand the cross section after approximate rectangle down, increased the area of contact of fixing device and soil, fixed throwing props more firmly.

In other embodiments, the connection part 5 is fixedly connected to the connection rod 9, and the connection rod 9 slides up and down to move the connection part 5 up and down.

When the device is used, the connecting rod 9 is hammered through auxiliary tools such as a large hammer, the whole connecting rod 9 passes through the fixing part of the throwing support, the upper inserting rod is inserted into soil, and then the connecting rod 9 is rotated in the forward direction, so that the upper inserting rod and the lower inserting rod are expanded; during dismantling, the connecting rod 9 is reversely rotated, so that the upper inserting rod and the lower inserting rod are contracted, then the connecting rod 9 is pulled out, the installation and the dismantling are convenient, and the fixing and the throwing support are stable.

The above embodiments are not intended to limit the scope of the present utility model, so: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
