JPS5922179Y2 - Connector for vertical formwork support and formwork - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a connector for connecting vertical formwork supports and formwork in concrete construction.

Conventionally, when connecting the vertical formwork support material 4 and the formwork 2, as shown in FIG. After engaging the plate 8, the hook bolt 6 whose head was inserted into the mounting hole 2a of the formwork 2 was tightened with a nut, but in this case, a rib 4a was required on the outer edge of the support member 4. Therefore, the cross-sectional shape becomes complicated, which increases the manufacturing cost of the support material 4, and the tightening with the hook bolt 6 also requires the support material 4.
Since this is carried out only at one angle, there is a drawback that the surface of the formwork 2 tends to change angles.

This idea improves on these issues so that it can always maintain the proper connection pattern, and can be easily manufactured in the factory and installed on-site.
The purpose is to provide a connector for vertical formwork supports and formwork that improves construction efficiency.

This invention will be explained below with reference to the drawings.
As shown in the figures and FIG. At one end side back part 3C of the long angle material 3b cut slightly longer than the narrow side of the formwork support material 1,
A short angle member 3a having the same shape whose length is the width of the back surface portion 3C is welded in such a manner that the longitudinal surface 3d of the short angle member is arranged at 90 degrees to the back surface portion 3C of the long angle member.

Next, a mounting hole 3f is provided in the vertical surface portion 3e of the long angle material for fixing the formwork 2, and a similar mounting hole 3g is provided in the vertical surface portion 3d of the short angle material connected to the formwork supporting material 1. The connector 3 of the bundle is constructed as follows.

As a result, when the coupling tool 3 is fixed to the narrow side position on one side of the vertical formwork support member 1 by bolting to the mounting hole 3g of the short angle member 3a, the formwork 2 disposed on this side
When the upper and lower joint end surfaces of the connector are placed on the upper surface of the connector 3, the mounting holes 2a and 3f of both sides match immediately and easily.
By inserting a bolt into this and tightening the nut, the vertical formwork support member 1 and the formwork 2 can be reliably connected.

As shown above, the connector 3 according to this invention is made by welding two long and short angle members in a rectangular arrangement back to back in an irregular shape. If the formwork 2 is tightly fixed to the narrow side of the joint 3 and its adjacent corners, a regular shape can be easily obtained. Connector 3 that can reliably maintain the normal posture and
Since it has a simple structure with only angle welding and two mounting holes 3f and 3g, it can be easily manufactured in the factory and installed on site.The low cost and improved workability make this type of formwork construction economical. This has the effect of increasing construction efficiency.
