Abstract

PURPOSE:To improve safety of a suspension tool for civil engineering works by attaching sandwiching members having block side holding portions and block bottom engagement portions and to be inserted into block recesses rotatably to support members having suspension hooks. CONSTITUTION:A hook portion 4a is disengaged from an engaged portion 5 and plate shaped members 2a are widened about shafts 1b in the arrow directions to receive a block 3 between the plate shaped members 2a. The plate shaped members 2a are then swung in the opposite directions to be inserted in the recesses in the block 3, the hook portion 4a is engaged with the engaged portion 5, the block 3 is sandwiched with the sandwiching members 2, and supported with engagement portions 2b. Under this condition, the block 3 is suspended with the support member 1 and transported in the air.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a suspension for transporting blocks used for forming retaining walls, earth retaining walls, or fences (hereinafter referred to as retaining walls, etc.) in civil engineering work, construction work, etc. It concerns metal fittings.

[Prior Art] Generally, blocks for forming retaining walls and the like are mass-produced (concrete) blocks in factories instead of expensive natural stones.

Conventionally, this (
Concrete) blocks are being transported from the factory 11 to a place 15 where retaining walls and the like will be formed.

That is, (1) Transport from the factory 11 to the material storage area 12 by truck using a general road.

■Materials are transported from the dumping area 12 to the construction site 13 using a small trough or the like using a newly established temporary transfer path.

■Using the newly established temporary transfer route U, the unicycle] will be transported to the construction site 13 or 1 to the masonry work site 14 using a Yumbo basket or the like.

Using the newly established temporary transport route ■, the stone is transported from the masonry work site 14 to the retaining wall formation site 15 only by hand by the worker σ.

I was doing transportation work.

Following this transport work, at the masonry work site, block laying work and work of packing concrete, maroon, etc. are performed.

[Problem M to be solved by the invention] As mentioned above, in the conventional method, the work is delayed because temporary construction work must be carried out in the temporary transport steps Construction work, such as masonry work, is hard work and dangerous because it is carried out mainly by the manual labor of workers. In addition, the transportation work using the Yumbo basket is dangerous because the blocks are not installed in an unstable manner, and the blocks are likely to fall. Moreover, in the masonry work, it is difficult to work on the existing blocks, so scaffolding must be installed one after another.

In addition, earth and sand may adhere to the blocks due to loading and unloading of the blocks during transportation or when they are left on earth and sand during the work period, hindering the concrete packing work, and also causing the blocks to stick together in the forming machine for retaining walls, etc. This had the problem that it weakened and became brittle.

This problem of soil adhesion can be solved by having workers brush it off when forming retaining walls, etc., but this work requires a considerable amount of time and effort.

Therefore, in order to solve each of the above-mentioned problems, the present invention provides a block having four groove-shaped parts on at least one side surface from its upper end to its lower end (for example, the present applicant's 1999+2JI 7 [ In addition to using the block disclosed in the patent application No. 10 entitled "Block, mold for its production, and method for forming retaining walls, retaining walls, and fences using the block," the block is easily and safely transported in the air. The purpose is to develop hanging metal fittings that can be used.

[Means for Solving the Problems] The hanging fixture for transporting blocks of the present invention includes a support member equipped with a hook for hanging with a crane, etc., and
The block includes a holding part for holding the side surfaces of the block facing each other, and a locking part formed at the lower end for placing the block, and the upper end is rotatably attached to the support member. At least one of the clamping members is configured to fit into the recess, especially when transporting a block having a recess on each of the opposing sides. The first holding part and the second holding part are fitted into the respective recesses to hold the block facing each other, and the first holding part is provided with an engaged part. The other clamping member is provided with an engaging portion that can be engaged and released from the engaged portion.

The holding of the block by fitting the clamping member into the recessed portion of the block may be performed only on one side of the block, or may be held on a plurality of side surfaces of the block.

[Operation J block is lifted and transported in the air by having its bottom surface hooked and stopped by the locking portions of the plurality of clamping members described above. At this time, since the clamping member is fitted into the groove-shaped recess of the block, the block does not slide relative to the clamping member.

[Example] An example of the hanging fitting of the present invention will be described with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a support member, which is equipped with a hook 1a for lifting with a crane or the like via a wire, and has a shaft portion 1 at each end.
b.

Reference numeral 2 denotes a clamping member, which is made up of a plurality of plate-like members 2a that fit into recesses 3a of the block, which will be described later.
It has an L-shaped locking portion 2b at its lower end, and the plate-like members are connected to each other by a fixing member 2c.

3 is a block for forming a retaining wall, etc., and is provided with a vertically curved recess 3a.

Reference numeral 4 denotes an engaging portion, which has a key portion 4a at one end and is rotatable about the other end attached to one fixing member 2c.

Reference numeral 5 denotes an engaged portion, which is formed into an annular shape for locking and locking the key portion 4a, and is attached to the other fixing member 2b.

A hanging metal fitting having the above-described structure is used to transport a block, which has been transported to a construction site 13 by a truck or the like, to a place 15 where a retaining wall or the like is to be formed.

At this time, first, in a state where the key part 4a and the engaged part 5 are not engaged, the plate-like member 2a facing the shaft part 1b as the center
is rotated in the direction of the arrow, and a block is inserted between the plate-like members 2a.Subsequently, the plate-like member 2a is rotated in the direction opposite to the direction of the arrow, and the concave portion 3a of the block 3 is grasped from both sides. At the same time, the key part 4a is engaged with the engaged part 5. (See Figure 2) Furthermore, by rotating the plate member 2a using power from a motor, spring, etc., it is possible to easily fit and disengage the clamping member 2 and the recess 3a of the block 3. can.

[Effects] The present invention is configured as described above, and provides the following effects.

■When in use, the clamping member fits into the concave part of the block, and the engaging part and the secured part keep the block in a gripped state, so the block may be damaged by shaking etc. This can prevent it from falling from the hanging fixture.

■Since the blocks are transported in the air, it prevents the adhesion of dirt and sand, increasing work efficiency and making it possible to form strong retaining walls, etc.

■Since blocks are transported using hanging metal fittings, no temporary transport path is required.

■Blocks can be loaded directly with a crane, etc.
The labor of the workers can be reduced, and there is no need for scaffolding for stacking blocks, which, combined with the above point (2), can shorten the construction period and reduce construction costs.
