Embodiment 1

[0046] like figure 1 and 2 As shown, the tongue-and-groove connection structure of the building formwork described in this embodiment has a pouring surface and an outer surface opposite to the pouring side plate; it is formed on the edge 2 between the pouring surface and the outer measuring surface There is a tongue-and-groove structure; the tongue-and-groove structure includes molding on the edge 2, the notch 31 faces the locking groove 3 parallel to the pouring surface, and a locking device arranged on the edge 2 of the adjacent template 1; the The locking device has a locking piece 4 that is relatively movably connected to the adjacent template 1 and is suitable for being embedded in the locking groove 3. The locking piece 4 cooperates with the locking groove 3 to prevent two adjacent templates 1 from interacting with each other. separate. In this embodiment, the setting of the locking member 4 and the locking groove 3 can not only realize the quick connection between the...

Embodiment 2

[0062] As a convertible implementation mode, the difference between this embodiment and embodiment 1 is:

[0063] like image 3 As shown, the locking member 4 is rotatably connected to the adjacent template by a pivot set parallel to the direction of the edge 2; the locking member 4 is rotated so that the locking head 41 and the locking surface Lamination. That is, in this embodiment, the locking member 4 can be mounted on the adjacent template 1 on the pivot, and it can rotate around the pivot, so that the locking head 41 is pressed against the locking surface. combined, thereby preventing the separation of two adjacent templates 1

[0064] In this embodiment, the locking members 4 rotate in opposite directions and are arranged in pairs, and the partial pressures in the direction perpendicular to the pouring surface cancel each other when pressed. Specific as image 3 As shown, the locking groove is provided with an intermediate T-shaped portion, the two lateral inner end...

Embodiment 3

[0066] As a convertible implementation mode, the differences between this embodiment and embodiment 1 are:

[0067] like Figure 4 and Figure 5 As shown, the locking groove 3 is at least one transverse groove arranged alternately along the extending direction of the edge 2; the locking member 4 is a locking hook arranged alternately along the extending direction of the edge 2 and corresponding to the transverse groove; Each of the locking hooks is rotatably connected to the adjacent formwork by a pivot perpendicular to the pouring surface. In the case of more than two locking hooks, a linkage rod keeps each of the locking hooks linked. . In this embodiment, the locking member 4 is set as a locking hook, and when two adjacent templates 1 are connected to each other, the locking hook rotates and engages with the transverse groove, thereby connecting the two templates 1 In the case of a plurality of locking hooks, the same linkage rod is used to drive the locking hooks to eng...

Abstract

The invention relates to a tongue and groove connecting structure of a building formwork. This structure has a casting surface and an outer side corresponding to outer casting side plates; an edge between the casting surface and the outer side forms a tongue and groove structure; the tongue and groove structure comprises locking grooves formed in the edge and opened parallelly towards the casting surface and comprises a locking device disposed on the edge of an adjacent formwork; the locking device has locking parts relatively movably connected to an adjacent formwork and suitable for being embedded in the locking grooves, and the locking parts cooperate with the locking grooves to prevent separation of two adjacent formworks. In this structure, the locking parts and the locking grooves are arranged to enable quick connection of the adjacent formworks and also enable prevention for the separation of the adjacent formworks, as well as connection strength of the adjacent formworks.

Description

technical field [0001] The invention relates to the construction field, in particular to a tongue-and-groove connection structure of a building formwork. Background technique [0002] The existing building formwork usually adopts a detachable connection method, and small pieces of formwork are assembled into the required modeling shape on site. One of the assembling and connecting methods is to set connecting holes on the non-casting surface of the formwork, use bolts to connect, or set connecting flanges, and use a quick clamping mechanism to realize the connection. There is also the use of tongue-and-groove joint structures on the opposite edges of the formwork connection for connection. The usual way of bolt connection and clamping mechanism connection needs to set at least two bolts or clamping mechanisms on the connecting edge of the formwork, and at the same time needs to perform leveling work on the pouring surface, which makes its work efficiency low and the flatnes...
