Template assembly connecting fastener

Abstract

A template assembly connecting fastener belongs to building moulding plate connector field, adopts a structure of an active chuck fastened with a wedge body. The chuck and the wedge body are integrated together to improve the assembly speed and quality of the moulding plate; the fastener has a chuck (1) with a fixed claw (2) fixed on a position body (4) and an active claw (3) hinged together with the position body (4) by a small shaft (5), and has a wedge body (6) hinged with the active claw (3) by a bearing shaft (7) mounted at the tail part of the active claw (3), the wedge body (6) has an angular slide track (8) for the bearing shaft (7); the beneficial points are that: the fastener is simple in structure, convenient in use, needs no perforating on the side frame of the moulding plate, is not easily to be damaged and lost, low in cost, long in use lift; the moulding plate can position and align by itself during the fastening process for the wedge body (6), the moulding plate can assembled and fastened reliably with high quality; the fastener is adapted for the assembly for various moulding plates.

Description

technical field [0001] The invention belongs to the field of building formwork connection devices, and relates to a formwork assembling connection jig. Background technique [0002] In the prior art, when building formwork, steel formwork or wooden formwork is assembled and connected, most of them use ordinary bolts and nuts to perforate the assembled connection. This traditional connection device has obvious shortcomings: slow construction speed, formwork The quality of assembly is not easy to guarantee, it is easy to be damaged at the construction site, and it is easy to loosen by itself after the earthquake, which sometimes seriously affects the quality of concrete pouring; there are also many enterprises that use such as: the assembly card disclosed in Chinese patent ZL99205850·3, its structure is : There are double hook feet on the main part, and there are fastening bolts with saddle-shaped plates opposite to the double hook feet.

[0002] In the prior art, when building formwork, steel formwork or wooden formwork is assembled and connected, most of them use ordinary bolts and nuts to perforate the assembled connection. This traditional connection device has obvious shortcomings: slow construction speed, formwork The quality of assembly is not easy to guarantee, it is easy to be damaged at the construction site, and it is easy to loosen by itself after the earthquake, which sometimes seriously affects the quality of concrete pouring; there are also many enterprises that use such as: the assembly card disclosed in Chinese patent ZL99205850·3, its structure is : There are double hook feet on the main part, and there are fastening bolts with saddle-shaped plates opposite to the double hook feet. When in use, there must be matching double holes on the frame of the formwork. Ride on the top of the two formwork frames, and then tighten the top bolts. The biggest advantage of this connection device is that the construction speed is fast, but there are still obvious shortcomings: the formwork frame must have standardized double holes. It is also easy to be damaged, and it is easy to loosen by itself after being shaken. At the same time, it has strict requirements on the inner size of the double hook feet. The quality of formwork assembly will inevitably affect the quality of concrete pouring; another example: the fixture scheme disclosed in Chinese patent ZL01271107·1 consists of three parts: a wedge with wedge teeth, and a left half clip with a rack and the right half of the card, when in use, the left and right half of the card are aligned on the frame of the template. At this time, the rack on the left half of the card passes through the groove of the right half of the card, and then the wedge The body is inserted from the longitudinal hole of the groove and meshed with the horizontal rack. When the wedge force is applied, due to the function of the helical teeth, the wedge teeth and the rack are engaged in a lateral displacement, thereby driving the two halves of the clips to tighten each other. combined; the biggest advantage of this kind of fixture is that the construction speed is fast, the formwork is assembled and fastened reliably, and there is no need to punch holes on the frame of the formwork, but there are high costs and other unsatisfactory parts; The disclosed new connector is mainly composed of special-shaped plate bolts and matching T-shaped spring wedges. It is stuck on the inner surface of the bolt head. After the wedge is tightened, the wedge body produces a certain elastic bending. Its biggest advantages are simple structure, convenient construction, wear resistance and collision resistance, and long service life. The disadvantage is that the wedge body The elastic bending is prone to fatigue, and the artificial wedging force is not easy to grasp. When using, the perforation fastening one by one still affects the construction speed, and it is also prone to loss, etc.
