Description

The present invention relates to a suspended scaffolding plate arranged side by side in a suspended state in order to construct a suspended scaffolding, and constructs a suspended scaffolding structure including an atypical suspended scaffolding plate having different fitting conditions for fitting means The present invention relates to an adapter device that can be used and an intermediate scaffold plate provided with the adapter device.

Conventionally, when an elevated structure such as an expressway or a bridge is constructed or repaired, a suspension scaffold is constructed along the extension direction of the elevated structure.

A suspension scaffold plate for constructing such a suspension scaffold is configured as shown in FIGS. 1 and 2, for example. The suspended scaffolding board 1A is formed in a rectangular frame shape by a pair of beam-side frames 3 and 3 that support both side edges of the flooring 2 and wife-side frames 4 and 4 that connect both ends of the beam-side frames 3 and 3. The flooring 2 is mounted on the girder side frames 3 and 3 and the girder side frames 3 and 3 constitute a girder side part (hereinafter sometimes referred to as “girder side part 3”). The frame 4 and 4 constitutes a wife side (hereinafter may be referred to as “wife side 4”), and the floor 2 constitutes a work floor (hereinafter may be referred to as “work floor 2”). ).

Therefore, as shown in FIG. 2, a plurality of suspended scaffolding plates 1A are suspended below the existing structure such as an elevated structure by means of a cable 5 such as a chain, and the girder side portions 3 are connected in parallel. While extending the work floor 2, a suspended scaffold construction is constructed. Normally, a suspended scaffold is constructed by sequentially arranging the suspended scaffolding plates 1A connected in series from a predetermined position toward one of the extending directions, but when the suspended scaffolding construct is described, The work floor 2 extends the work floor 2 in a first direction X1 extending from one girder side portion 3 of the suspended scaffolding plate 1A and a second direction X2 extending from the other girder side portion 3.

In order to enable suspension by the rope 5, the suspension scaffolding plate 1 </ b> A is located below the flooring 2 and a center frame 6 is installed between the wives side frames 4, 4. A hanging metal fitting 7 made of a metal ring is arranged at an interval in the axial direction, and the rope 5 is connected with the hanging metal fitting 7 protruding from the window hole 8 of the flooring 2, The center frame 6 is suspended through the metal fitting 7.

As described above, in order to enable the plurality of suspension scaffolding plates 1A to be sequentially arranged in a connected state, the suspension platform plate 1A is connected to the first girder side portion 3 of the girder side portions 3 and 3 on both sides. 9 A of 1 fitting means is provided, 10 A of 2nd fitting means is provided in the other spar side part 3, and the 1st fitting means 9 and the 2nd fitting means 10 are several adjacent scaffolds provided in parallel There are provided “fitting conditions” that allow the girder sides 3 and 3 of the plates 1A and 1A to be connected to each other.

In the case of the suspended scaffolding plate 1A illustrated in FIG. 1, the first fitting means 9A is constituted by circular pipe-shaped plugs 11, 11 projecting concentrically from one end of the wife side frames 4, 4. Is provided with a locking hole 12. On the other hand, 10 A of 2nd fitting means is comprised by the sockets 13 and 13 formed in the other end part of the wife side frames 4 and 4, and has provided the locking pin 14 which can be inserted or detached.

In order to provide the above-mentioned “fitting condition”, the distance between the shaft centers of the pair of plugs 11 and 11 and the distance between the shaft centers of the pair of sockets 13 and 13 are designed to be equal to the distance L1. The outer diameter and the inner diameter of the socket 13 are designed so that they can be fitted. The locking pin 14 is designed to be locked in the locking hole 12 in a state where the plug 11 is inserted into the socket 13. Therefore, by providing such “fitting conditions”, the first fitting means 9A of one suspended scaffolding board 1A and the second fitting means 10A of the other suspended scaffolding board 1A arranged in parallel are mutually connected. Can be fitted.

Furthermore, it is preferably formed so as to have “alignment conditions” so that the work floors 2 and 2 of the suspended scaffolding plates 1 </ b> A and 1 </ b> A that are arranged side by side are aligned. The distance to the axis of the socket 13 and the distance to the axis of the socket 13 are designed to be equal to the dimension H1, and the distance from the end face of the spar frame 3 to the axis of the plug 11 and the axis of the socket 13 are designed. The distance is designed to have an equal dimension S1.

As a result of the above, the plurality of suspended scaffolding plates 1A, 1A arranged side by side with each other by fitting the first fitting means 9A and the second fitting means 10A having “fitting conditions” to each other. It is possible to connect the parts 3 and 3 in a connected state, and by adhering the first fitting means 9A and the second fitting means 10A having the “matching condition”, adjacent suspended scaffolds It is possible to extend the work floor in an aligned state without causing irregularities such as steps between the work floors 2 and 2 on the plate.

By the way, with the widespread use of suspension scaffolds, the first fitting means is caused by various causes such as model changes due to enhancement of production facilities, structural changes according to user requests, and design changes due to differentiation from other companies' products. It is expected that a different type of suspended scaffolding plate having a different type of the second fitting means will be provided. At this time, even if there is no difference in the outer dimensions due to the girder-side dimensions and the wife-side dimensions of the suspended scaffolding plate, there is a possibility that the above-mentioned “fitting conditions” will be different.

For example, when the suspended scaffolding plate described with reference to FIGS. 1 and 2 is a first type suspended scaffolding plate 1A, the first type suspended scaffolding 1A is provided as illustrated in FIGS. There is a possibility that a second type foot suspension board 1B having another “fitting condition” different from the “fitting condition” may be provided.

In the case of the second type of suspended scaffolding plate 1B shown in FIGS. 3 and 4, a pair of plugs 15 each comprising a square pipe in which a first fitting means 9B provided on one girder side portion 3 is projected from the girder side frame 3. 15, the plug 15 is provided with a locking hole 16, and the second fitting means 10 </ b> B provided in the other spar side part 3 is constituted by a pair of sockets 17, 17 formed by square pipes. A locking pin 18 that can be inserted and removed from the upper part of the girder frame 3 is provided toward the socket 17.

As shown in FIG. 4, the second type suspension scaffolding plate 1B itself can be provided with a plurality of the same type suspension scaffolding plates 1B, 1B in a connected state. The two fitting means 10B has a “fitting condition” in which a plurality of adjacent suspended scaffolding plates 1B and 1B connected to each other can be fitted to each other between the side portions 3 and 3 connected to each other. .

That is, as shown in FIG. 3, the distance between the center of the pair of plugs 15 and 15 and the distance between the centers of the pair of sockets 17 and 17 are designed to be the same distance L2. The square shape is designed to have a shape and size that can be fitted. The locking pin 18 is designed to be locked in the locking hole 16 in a state in which the plug 15 is inserted into the socket 17, and the first fitting means 9B and the second fitting means 9B “Fitting condition” is provided between the fitting means 10B.

In this connection, it is preferable to form so as to also have “alignment conditions” so that the work floors 2 and 2 of the side-by-side scaffolding plates 1B and 1B are aligned, and from the upper surface of the beam side frame 3 to the center of the plug 15 And the distance to the center of the socket 17 are designed to have the same dimension H2, and the distance from the end face of the girder frame 3 to the center of the plug 15 and the distance to the center of the socket 117 are equal to the dimension S2.
