Abstract

PURPOSE:To make it easy, lightweight and safe to handle without using anchors by making it possible to constitute so that mechanisms operated by a lever having a guideway can engage with each other. CONSTITUTION:A grip holding section 13 fixed to the lower part of a bearing section of a bearing stand 6 is slid within a range of dimension (L) vertically limited along a shaft 3 by manual operation. Hook-like hangers 1 and 2 are opened by the manual operation, the lower part of a PC bridge is lightly held, and it is pulled downward to hold strongly. Holding force is getting stronger as load is applied, so that no slippage is made by gravity. However, in consideration of such a case that fixed arms 9 and 10 required to operate downward are forcedly pushed upward by some sort of force, a safety-pin 14 coming into contact with the lower bottom of the grip holding section 13 penetrates the shaft 3. Safety rope hanging cut sections 15 and 16 are provided to the hangers 1 and 2, and double prevention is made against unintentional falling of hangers.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention mainly relates to a temporary hanging hanger for scaffolding suspended from the lower part of a PC bridge.

(Prior art) As a conventional hanging hanger for scaffolding, there is no hanger that can be easily and safely suspended from the bottom of a PC bridge due to its structure.
Measures were taken to secure it by driving anchors into the bridge.

(Problems to be Solved by the Invention) In the above-mentioned prior art, there remained problems such as requiring a lot of construction work to drive and fix the anchors to the PC bridge, and the anchors had to be left in place or removed.

(Means for Solving the Problems) The present invention has been made in response to the demand for improvement without using the above-mentioned drawbacks, and aims to realize a hanging hanger for scaffolding that is easy to handle, lightweight, and safe without using anchors. It is something.

To this end, the mechanism was designed so that mechanisms operated by levers with sliding surfaces can engage with each other.

With this configuration, when a load is applied, the lower part of the PC bridge can be gripped even more strongly, and safety ropes or safety pins can be used together, making it extremely safe.

Namely, 1. Hook-shaped hangers (1) and (2) made of a hard material or a polymeric material and separated from each other in a symmetrical manner.(2) A hook-shaped hanger made of a hard material or a polymeric material and having a cross-sectional shape arranged at the center of the left and right sides. The hanger () protrudes through the left and right fulcrums (5) and (6) of a bearing stand (4) made of a hard material or polymeric material that holds an arbitrary shaft (3) so as to move up and down. 1)
The fixed arms (9) and (10) on the left and right sides of the head of the shaft (3) are brought into contact with the upper surface of the lower lever part (7) and (8) of (2), and are slid down within a limited range by sliding frictional contact action. A hard member is fitted between the bearing stand (4) and the fixed arms (9) (10) on the left and right sides of the shaft (3) on the lower sloped part of the lower lever part (7) (8). The bearing base (4) and the upper spring seat (11) are brought into contact with each other by making contact with the upper spring seat (11), which is made of a material or a polymeric material and can move up and down along the shaft (3). ), the lower lever parts (7 ) (8) is always pressed upward within a limited range to provide a sliding frictional contact effect, so that the hangers (1) and (2) can be operated to grip or release an object.

2. In the bearing stand (6), a space is provided for the grip support part (13) fixed to the lower surface of the bearing of the bearing stand (6) to facilitate manual operation, and the grip support part (13) of the shaft (3) is 13), the safety pin (14) is inserted into the position in contact with the bottom surface of the lower part of the safety pin (14).

3 Notches (15) (1) in the hangers (1) (2).
6) was installed, the robe was stretched, and a plurality of temporary hanging hangers were connected and supported.

(Function) The operation of the above-mentioned configuration is to manually move the shaft (3) up and down in the axial direction using the grip support part (13) fixed to the lower surface of the bearing of the bearing stand (6). Slide within a limited range of movement.

Open the hook-shaped hangers (1) and (2) by this manual action,
When the lower part of the PC bridge is lightly grasped and pulled downward, the lower part of the PC bridge is strongly grasped, and when a load is applied, the lower part of the PC bridge is grasped even more strongly, and it will not come off due to gravity.

However, considering the case where some force acts from below upwards and pushes up the fixed arms (9) and (10) that should move downward, the shaft (3) is attached to the lower bottom surface of the grip support part (13). The safety pin (14) was inserted into the hole.

Furthermore, the hangers (1) and (2) are provided with notches (15) and (16) for safety hooks, thereby doubly preventing the hangers from falling.

(Embodiment) An embodiment of the present invention will be described in detail based on the drawings. 1. Hook-shaped hangers (1) and (2) that are symmetrical and separated from each other made of aluminum; lower lever portions (7) on the left and right sides; (8) The upper surface and the semicircular part at the tip, and the flat surface of the fixing arms (9) and (10) on the left and right sides of the head of the mild steel shaft (3) located at the center of the left and right sides of the hanger (1) and (2). The shaft (3
) The lower lever portions (7) and (8) are supported via the left and right support points (5) and (6) of the light alloy bearing stand (4), which is held so as to move up and down along the vertical axis. The bearing stand (4
) and the shaft (3) fixed arms on the left and right sides of the head (9) (1
A light alloy upper spring seat (11) fitted between the bearing base (4) and the upper spring seat (11), which is fitted between the shaft (3) and can freely move up and down along the shaft (3), is brought into contact with the bearing base (4) and the upper spring seat (11). ), a compression coil spring (12) strong enough to operate the lower lever parts (7) and (8) of the hangers (1) and (2) is fitted and resiliently installed between the lower lever parts (7) and the lower lever parts (7). ) (8) is always pressed upward within a limited range to provide a sliding frictional contact effect, so that the hangers (1) and (2) can be operated to grip or release an object.

2. In the bearing stand (4), a space is provided for the grip support part (13) fixed to the lower surface of the bearing of the bearing stand (4) to facilitate manual work, and the grip support part (13) of the shaft (3) is 13) A safety pin (14) was inserted in the position where it touches the bottom of the lower part in case it comes off.

3 Notches (15) (1) in the hangers (1) (2).
6), ropes were stretched, and multiple temporary hangers were connected and supported.

(Effects of the Invention) The above-mentioned structural action eliminates the work of driving anchors and increases the practical value, so it is expected that the application will be expanded beyond just PC bridges.
