Abstract

The invention discloses a quick installation and disassembly device for the internal corner formwork of a wall in a cast-in-place concrete project, which is mainly used for correcting angles, aligning plate seams, and quickly reinforcing and dismantling, including: two C-shaped chutes for fixing the formwork body Light steel slide rail, 1 set of adjustable length inclined steel pipe, 1 set of adjustable length steel pipe with hypotenuse center line and 3 connecting slides, 2 vertical adjustment gears, 1 center line rod rotating rod. When installing (removing) the inner corner formwork of the wall, insert the rotating rod into the rotation hole of the centerline rod, rotate the centerline rod until the outer end gear is completely meshed with the gear of the slanting tube, and the total length of the centerline rod is exactly the full length of the slanting rod Half of the chute on both sides is also in the vertical state of the horizontal plane; rotating the centerline rod drives the gear of the diagonal support tube to rotate, and at the same time drives the slider in the chute to move outward or inward. When the outward slider enters (or exits) the adjacent formwork level When back corrugated, the corner formwork and the adjacent formwork are joined together (or separated), and the formwork has been installed (dismantled) so far.

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 internal corner formwork of the wall, including: two C-shaped chute light steel slide rails for fixing the formwork body, one set of adjustable length inclined steel pipes, one set of Adjustable length steel pipe with hypotenuse center line, 3 connecting slides, 2 vertical adjustment gears, 4 fixed lugs.

Preferable one, the hypotenuse midline adjustable length steel pipe is composed of 2 sections of Φ20 steel pipe and 1 Φ20 steel straight thread casing, the outer end is welded with a conical threaded disk, when the threaded disk rotates, the centerline steel pipe rotates at a double speed Rotate out or screw in at a high rate; at the same time, it drives the diagonal steel pipe to rotate, extending or shortening at 2 times the rate, thereby keeping the angle between the slide rails of the chute always at a right angle.

The second option is that the adjustable length inclined steel pipe is composed of 3 sections of Φ20 chrome-plated steel pipe and two Φ20 chrome-plated steel straight thread casings, and a conical ductile steel threaded disc is welded in the middle. Rotate to lengthen or shorten, and at the same time drive the slide rail to move outward or inward horizontally, so as to keep the angle between the two slide rails always at right angles.

The third option is that the C-shaped chute slide rail 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 rails of the shortcut device horizontally on the wall formwork with screws, install the diagonal brace on the chute block, and install the centerline pole on the wall formwork. On the right-angle plate, insert the rotating rod into the rotation hole of the center line rod, rotate the center line rod until the outer end gear is completely meshed with the gear of the slanting tube, at this time the total length of the center line rod is just half of the total length of the diagonal rod, and the chutes on both sides It is also in the vertical state of the horizontal plane; rotating the center line rod drives the gear of the diagonal support tube to rotate, and at the same time drives the slider in the chute to move outward or inward. The seams are connected as a whole, and the two internal corner formworks are also in a vertical state, and the formwork installation is complete.

When the formwork is removed: reversely rotate the steel pipe at the outer end of the center line to move the oblique support pipe 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, and the support device Function complete.

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

Detailed ways

Embodiment 1: When the template is installed,

After the wall formwork with vertical back corrugation is in place as required, this quick device is horizontally fixed on the inner corner formwork with wood screws according to the design requirements, and the steel pipe 10 at the outer end of the center line is rotated to make the oblique support pipe 9 move outward as a whole , until the slide block 5 is drawn into the transverse reinforcement pipe of the adjacent formwork, so that the joints of the two inner corner formworks and the respective wall formworks are tightly squeezed, the success of the reinforcement of the inner corner formwork can be declared.

Embodiment two: when the formwork is removed:

Reversely rotate the steel pipe 10 at the outer end of the center line to move the oblique support pipe 9 inward as a whole until the sliding block 5 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. The function of the support device Finish.

Therefore, the device of the present invention can quickly adjust the angle of the formwork, realize fast alignment with the adjacent formwork, and quickly remove the wall formwork. The process is simple and the operation is convenient. It improves the work efficiency and reduces the construction cost. It is an indispensable on-site construction tool.
