Description

Quick installation and disassembly device for wall internal corner formwork

technical field

The invention relates to a technique for quickly straightening, square-keeping, reinforcing and dismantling support of formwork supports at inner corners of a wall.

technical background

In the construction of modern concrete structure buildings, the formwork engineering of the wall column internal corner is a relatively common formwork support process, with a large amount and a wide area; but the support method is either to add the internal corner formwork, or to use two large wall formworks The result of direct reckless fight is that it is difficult to fight corners, the angles are not square, there are many phenomenon of die-cutting and plugging, and the appearance quality of the project is poor. It takes a lot of work and the speed is slow.

However, adopting the device of the present invention can not only eliminate the above-mentioned disadvantages of the process, but also can quickly adjust the angle of the formwork when installing the formwork at the inner corner of the wall, realize rapid alignment with the adjacent formwork, and quickly remove the wall formwork. The process is simple, It is easy to operate, can fully meet the needs of quick matching and quick installation of on-site formwork engineering, improves work efficiency, and reduces construction costs. It is an indispensable on-site construction tool.

Contents of the invention

The purpose of the present invention is to provide a convenient device for alignment and square finding, fast seam alignment, and installation and disassembly during the erection process of the formwork for internal corners of the wall, which can facilitate construction by workers, improve labor efficiency, and reduce construction costs.

In order to achieve the above purpose, the present invention provides a quick installation and disassembly device for the inner corner formwork of the wall, including: two C-shaped chute light steel slide rails for fixing on the inner corner formwork, and one set of adjustable length inclined steel pipes , 1 set of adjustable length steel pipes on the hypotenuse center line, 3 connecting slideways, 2 vertical adjustment gears, and 4 fixed ear plates. Half of the length, the two C-shaped chute light steel slide rails are installed vertically, and the two C-shaped chute light steel slide rails and their vertical joints are respectively provided with a connecting slideway falcon, and one set can be The two ends of the length-adjustable oblique steel pipes are respectively installed on the connecting slideways on the light steel slide rails of the two C-shaped chutes, and one end of the set of adjustable-length steel pipes on the hypotenuse center line is installed on the two C-shaped slide rails. The two vertical adjustment gears are conical ductile steel threaded disk and tapered threaded disk;

The hypotenuse midline adjustable length steel pipe is composed of 2 sections of Φ20 steel pipe and one Φ20 straight threaded steel casing, the Φ20 steel pipe and the straight threaded steel casing are spaced apart, and the hypotenuse midline adjustable length steel pipe A conical threaded disc is welded on the outer end, and the conical threaded disc is engaged with the conical ductile steel threaded disc. When the conical threaded disc rotates, the center line of the hypotenuse can be adjusted in length by 1 Rotate out or screw in at double speed; at the same time drive the adjustable length inclined steel pipe to rotate, and extend or shorten at twice the speed of the adjustable length steel pipe on the hypotenuse center line, and then keep the light steel slide of the C-shaped chute The angle between the rails is always a right angle;

The adjustable-length oblique steel pipe is composed of 3 sections of Φ20 chrome-plated steel pipe and two Φ20 chrome-plated steel straight-thread casings, the chrome-plated steel pipe and the chrome-plated steel straight-thread There is a tapered ductile steel threaded disk, when the tapered ductile steel threaded disk rotates, the adjustable-length inclined steel pipe is rotated to lengthen or shorten at a rate of 2 times, and at the same time drives the two ends of the adjustable-length inclined steel pipe The connecting slideway falcon moves horizontally outward or inward along the light steel slide rail of the C-shaped chute, so as to keep the angle between the light steel slide rails of the two C-shaped chute always at right angles;

The light steel slide rail of the C-shaped chute is made of light C-shaped steel C48×48×15×3, and it must be matched with the horizontal reinforcement pipe of the adjacent wall formwork.

When installing the internal corner formwork of the wall, after the two corner formworks are in place, fix the two C-shaped chute light steel slide rails of the shortcut device horizontally on the wall formwork with screws, and install the adjustable length inclined steel pipe on the chute block Above, the hypotenuse center line adjustable length steel pipe is installed on the right angle plate, insert the rotating rod into the rotation hole of the hypotenuse center line adjustable length steel pipe, rotate the hypotenuse center line adjustable length steel pipe, and adjust the gear and the adjustable length vertically to the outer end The vertical adjustment gear of the inclined steel pipe is fully meshed. At this time, the length of the adjustable length steel pipe on the center line of the hypotenuse is exactly half of the length of the adjustable length inclined steel pipe. The centerline adjustable length steel pipe drives the vertical adjustment gear of the adjustable length inclined steel pipe to rotate, and at the same time drives the slider in the light steel slide rail of the C-shaped chute to move outward or inward. When the outward slider enters the adjacent formwork horizontal back groove, The corner formwork and the adjacent formwork are joined together, and the two inner corner formworks are also in a vertical state, and the formwork is installed.

When the formwork is removed: reversely rotate the steel pipe at the outer end of the center line, so that the adjustable length inclined steel pipe moves inward as a whole, until the sliding block draws out the transverse reinforcement pipe of the adjacent formwork, so that the corner formwork is separated from the large wall formwork, and the corner formwork can be removed to support The device function is complete.

The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
