Further comprising two end plates, the two end plates are oppositely disposed, and the end plates are respectively disposed on the first side plate, and the end plates are respectively provided with a hole.

Further comprising two end plates, the two end plates are oppositely disposed, and are respectively disposed on the second side plate, and the end plates are respectively provided with a hole.

Further comprising two end plates, the two end plates are oppositely disposed, and the end plates are disposed at the corners of the gussets, and the end plates are respectively provided with a hole.

The outer surface of the end plate and the gusset joint is a flat surface.

The second side plate is provided with a sleeve for inserting the lock bar.

The end of the rod member located outside the second side plate is provided with a lock handle, and the lock handle and the lock tongue extend in the same direction.

After adopting the above structure, a concrete formwork fixing device of the present invention has the following beneficial effects: when pouring concrete, the concrete formwork is spliced together according to the required formation, and a fixed pipe for fixing the concrete formwork can be erected around the concrete formwork. A corner mounting fixture formed at the joint of two concrete slabs. The rib is first inserted into the T-shaped groove on the surface of one of the concrete stencils, and the first side plate abuts on the surface of the other concrete stencil; then, the lock lever is rotated to rotate the lock tongue and then get caught in the T-shaped groove. In this way, the fixing device is installed on the concrete formwork, so that the adjacent two concrete formworkes are stably spliced together, and even if the size of the concrete formwork is large, the concrete formwork can be ensured not to be inclined externally, which is favorable for concrete pouring. forming.

In order to further explain the technical solutions of the present invention, the present invention will be described in detail below by way of specific embodiments.

As shown in the first to seventh figures, a concrete formwork fixture of the present invention includes a gusset (1) and a lock member (2).

The gusset (1) has a first side plate (11) and a second side plate (12) which are vertically connected to each other, and a joint of the first side plate (11) and the second side plate (12) forms a corner In the portion [not shown], the outer surface of the second side plate (12) is provided with two ribs (13), and the two ribs (13) are respectively parallel to the intersection of the corners.

The lock member (2) comprises a rod member (21) and a lock tongue (22), one end of the rod member (21) is located outside the second side plate (12), and the other end of the rod member (21) The bolt (22) is mounted through the second side panel (12) and protrudes from the middle of the two ribs (13), and the two ribs (13) are provided corresponding to the bolt (22). A notch (131) outside the rib (13) is spun out at the end of the locking tongue (22). The sleeve (14) for inserting the rod member (21) is disposed on the second side plate (12). A locking member (23) is disposed at an end of the rod member (21) outside the second side plate (12), and the locking handle (23) and the locking tongue (22) extend in the same direction.

As a preferred embodiment of the present invention, there are further included two end plates (3), two end plates (3) are oppositely disposed, and the end plates (3) are respectively disposed on the first side plate (11) The end plate (3) is respectively provided with a hole (31). In addition, two end plates (3) may also be oppositely disposed on the second side plate (12), or two end plates (3) may be oppositely disposed at the above-mentioned corners of the gusset (1). Preferably, the outer surface of the junction of the end plate (3) and the gusset (1) is planar. In addition, the second side panel (12) is provided with a notch (121), which can provide more space for holding the lock handle (23) to rotate the locking tongue (22).

When the concrete (2a) is poured, the concrete formwork (1a) is spliced together according to the desired formation, and a fixed pipe for fixing the concrete formwork (1a) may be erected around the concrete formwork (1a). A corner mounting fixture is formed at the joint of the two concrete formwork (1a). First, the rib (13) is inserted into the T-shaped groove (11a) on the surface of one of the concrete templates (1a), and the first side plate (11) abuts on the surface of the other concrete formwork (1a); The lock lever (21) rotates the lock tongue (22) and is caught in the T-shaped groove (11a). Thus, the fixing device is mounted on the concrete formwork (1a) so that the adjacent two concrete formwork (1a) are securely joined together, even if the size of the concrete formwork (1a) is large, it is ensured. The concrete formwork (1a) is not inclined outside, which is advantageous for concrete pouring molding.

After installing the fixing device on the concrete formwork (1a), use a wire to pass through the hole (31) in the end plate (3) and fix the end of the wire, and then fix the other end of the wire to the above fixed pipe. Or other components, the concrete plate (1a) can be prevented from tilting or turning inward by the pulling action of the steel wire, thereby preventing the concrete formwork (1a) from shaking, which is favorable for concrete pouring molding.

In addition, the present invention can also be used to form a staircase, as shown in the sixth figure, specifically as follows: the first step of forming a staircase between the first concrete formwork (3a) and the second concrete formwork (4a) disposed opposite each other The third concrete formwork (5a) and the fourth concrete formwork (6a), the third concrete formwork (5a) and the fourth concrete formwork (6a) are perpendicular to each other, and the third concrete formwork (5a) and the fourth concrete formwork (6a) are respectively The joint between the first concrete formwork (3a) and the second concrete formwork (4a) forms a corner [not shown] at which the fixture is mounted.
