DESCRIPTION OF EMBODIMENTS

The technical solution in the embodiment of the present disclosure will be described clearly and completely with reference to the attached drawings. Obviously, the described embodiment is only part of, rather than all of the embodiment of the embodiments of the present disclosure. Based on the embodiment in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present disclosure.

Referring to FIGS. 1-8, the present disclosure provides a technical solution, which is convenient for safe and efficient assembly and disassembly. The formwork 1 includes an aluminum profile frame 12 and a plywood 11 nested at the top of the inner cavity of the aluminum profile frame 12, wherein the plywood 11 is made of a wood material. An aluminum profile back rib 121 whose top surface is attached to the bottom surface of the plywood 11 is fixedly connected between the side walls of the inner cavity of the aluminum profile frame 12, and aluminum reinforcing pipes 122 are fixedly connected at positions of the inner cavity side walls of the aluminum profile frame 12 near the four corners, so that the whole formwork 1 not only has enough rigidity and strength, but also realizes light weight and greatly reduces the labor intensity of construction workers.

The four corners of the plywood 11 are respectively provided with 45-degree chamfered edges, and the positions of the aluminum profile frame 12 corresponding to the chamfered edges of the plywood 11 are respectively provided with gaps.

The corner parts 2 are detachably fixed at the four corners of the aluminum profile frame 12. The corner part 2 includes a middle corner plate 21, wing plates 22 fixed at two sides of the middle corner plate 21 and perpendicular to each other, a middle platform 23 which is fixed at a top end of the middle corner plate 21 and a top surface of which is attached to a bottom surface of the corner of the plywood 11, and a side platform 24 which is fixed at top ends of the wing plates 22 and a top surface of which is supported on the aluminum profile frame 12. The wing plate 22 is provided with a plurality of connecting holes 221, and bolts sleeved in the connecting holes 221 are configured for fixing the wing plates 22 on the side walls of the aluminum profile frame 12; a bottom end of the vertical edge 25 is vertically fixed at an edge of the middle platform 23, and the inner side walls of the vertical edge 25 are attached to the chamfered edge of the four corners of the plywood 11; the top end of a vertically extending cylindrical pin 26 is fixed to the middle of the bottom surface of the middle corner plate 21, and the bottom end of the cylindrical pin 26 has a spherical structure.

The middle corner plate 21, the wing plate 22, the middle platform 23, the side platform 24 and the vertical edge 25 are integrally formed, and the top end of the cylindrical pin 26 is welded to the bottom surface of the middle corner plate 21.

The vertical edge 25 and the aluminum profile frame 12 completely enclose the periphery of the plywood 11 to protect the periphery of the plywood 11 from impact and damage; in addition, the top of the side wall of the inner cavity of the aluminum profile frame 12 and the attaching positions between the top of the side wall of the inner cavity of the aluminum profile frame (12) and an inner side wall of the vertical edge (25) and the plywood (11) are filled with sealants respectively to protect the plywood 11 from moisture and prevent the plywood 11 from being cracked by blisters, thus greatly prolonging the service life of the plywood 11.

The upright post component 4 includes a square vertical tube 41, a connecting plate 42 fixed at the bottom of the square vertical pipe 41 and detachably and fixedly connected with the top of the steel support 3, and a top plate 43 which is fixed at a top end of the square vertical pipe 41 and a side edge of which is attached to an outer side wall of the vertical edge 25; the top plate 43 is a square plate. An upper limit pin 44 and a lower locking pin 45 perpendicular to each other are respectively sleeved on the upper side and the lower side of the middle part of the square vertical pipe 41 in the horizontal direction.

The support seat 5 comprises a square support plate 51 and side plates 52 fixed at outer edges of a top surface of the support plate 51; the mounting grooves 522 are provided at the top parts of the two ends of the side plate 52, and a middle part of the support plate 51 is provided with a square hole 511 which is matched and muff-coupled with the square vertical pipe 41 in a sliding manner. The support plate 51 is provided with notches 512 which are vertically engaged and matched with the two ends of the lower locking pin 45 in a sliding manner.

The locking block 6 includes a block 61 and wedge-shaped locking strips 62. One end of the middle part of the block 61 is provided with an unlocking groove 63, and the other end of the middle part of the block 61 is provided with a locking groove 64 communicating with the unlocking groove 63. The wedge-shaped locking strips 62 are provided on both sides of the locking groove 64, and the locking groove 64 is slidably engaged with the square vertical pipe 41 in the horizontal direction. The distance between the front and rear walls of the unlocking groove 63 is not less than the length of the lower locking pin 45. The bottom surface of the wedge-shaped locking strip 62 is provided with a slope.

To sum up, when assembling the whole deck building formwork, the square vertical pipe 41 is in the unlocking groove 63, and at the same time, the vertical pipe 41 moves the support seat 5 and the locking block 6 upward until the top surface of the support plate 51 abuts the bottom of the upper limit pin 44. At this time, the locking block 6 is knocked horizontally, so that the locking groove 64 gradually slides to the direction of the square vertical pipe 41, and at the same time, the bottom surface of the wedge-shaped locking strip 62 gradually slides along the top of the lower locking pin 45, until the wedge-shaped locking strip 62 is locked with the lower locking pin 45, and at this time, the support seat 5 is firmly locked on the square vertical pipe 41. Then, only the spherical structure at the bottom end of the cylindrical pin 26 need to be vertically engaged in the mounting groove 522, that is, the convex parts at both sides of the spherical structure are respectively engaged in the mounting groove 522 near the two sides of the corner of the support seat 5 during installation. Due to the self-weight of the whole formwork 1, the spherical structure will be firmly engaged into the mounting groove 522, thus realizing the installation of the formwork 1.

When assembling a plurality of formworks 1, the four sides of the top plate 43 are respectively attached to the outer side walls of the corresponding vertical edges 25, forming the structure as shown in FIG. 8, so that the panel structure formed by the formworks 2 is flat and stable.

When the formwork 1 is dismantled, the side of the locking block 6 is struck horizontally with a hammer to make it move in the horizontal direction. As the square vertical pipe 41 enters the unlocking groove 63 from the locking groove 64, the locking relationship between the wedge locking strip 62 and the lower locking pin 45 is released. At this time, due to the action of gravity, the support seat 5 and the locking block 6 will slide downward relative to the square vertical pipe 41, such that the spherical structure at the bottom end of the cylindrical pin 26 is disengaged from the mounting groove 522; in this way, the formwork 1 can be taken down until the cylindrical pins 26 corresponding to the four corners of the formwork 1 are separated from the mounting grooves 522 on the support seat 56.

In order to facilitate the connection of the inclined support structure, two side walls of the middle corner plate 21 are respectively provided with reserved holes 211.

In order to further reduce the overall weight of the deck formwork assembly, the middle parts of the side plates 52 are respectively provided with weight-reducing grooves 521.
