Description

The present invention relates to a joint form for a basic transverse block.

In the prior art document, the joint form configuration in the standard block of FIG. 10 is disclosed.
As a conventional joint formwork configuration, there has been disclosed a measure for preventing the mortar from falling around the mortar and reducing the amount of the mortar when the mortar is placed for stacking the standard blocks. (Patent Document 1, Patent Document 2). In addition, there is a configuration in which a trumpet-shaped receiving port and slide moving iron measure are provided to prevent spillage of the toro (Patent Document 3), and a structure in which the hollow portion of the hollow concrete block is closed with a mold (Patent Document 4). It is disclosed. If these techniques are used, the operation of placing joint mortar with a solid structure can be carried out without any problem. However, these prior art documents do not describe a configuration in consideration of insertion of horizontal reinforcing bars and vertical reinforcing bars. In fact, it is known that many block collapses occurred in the 1995 Hanshin-Awaji Great Earthquake in the block fence using the conventional joint formwork configuration.

In the prior art, in order to correspond to the thickness of the block defined in Japanese Industrial Standard, the entire frame must be manufactured to a dimension corresponding to the thickness. This requires extra materials and production costs. Further, since the height of the mortar joint frame is constant, there is a problem that the joint height cannot be adjusted and workability is poor. Furthermore, in the prior art, since only the basic block is targeted, it is not possible to attach a horizontal rebar, so it is difficult to meet the seismic standards. For this reason, there is a problem that if there is a big earthquake, the possibility of collapse is high.

  Further, in the prior art, the linearity in the horizontal direction of the block (work progress direction) and the horizontality and height of the block itself are based on the water thread, so that there is a problem that skill is required. .

Further, according to the prior art, when the joint formwork tool is operated in the summer heat, the degree of hardness of the joint mortar changes depending on the time elapsed from the time of kneading the joint mortar to the time of placing the joint mortar. The fluidity of the block and the bondability of the block may deteriorate. In order to prevent this, it is necessary to replenish water, replenish cement, etc., and there is a problem that extra materials and labor work are required.

In order to solve the above-mentioned problems, the joint frame for the basic type transverse stripe block of the present invention includes two long side direction frame plates and two short side direction frame plates, and the long side direction frame plate includes Has a through-hole provided in a predetermined position and an arc-shaped opening, etc., and the short-side direction frame plate has a fixing rod and a fixing member screw hole protruding at an end thereof, and the short-side direction It has a mechanism that allows the joint height to be adjusted by inserting the fixing rod of the frame plate into the through hole of the long side direction frame plate and fixing it to the fixing member screw hole with a fixing member. .

The joint type frame for the basic transverse block of the present invention can obtain a constant height and levelness by a simple operation of pressing the joint mortar lightly with a joint iron, and can be finished accurately and cleanly. it can. In particular, the mortar joint height can be easily adjusted even when the so-called water-cement ratio such as the amount of water or the amount of cement changes in the summer or the cold, and the working efficiency is further improved. The basic transverse bar block has the structure shown in FIG. In particular, in summer, the water content is greatly reduced by the lapse of time from kneading to mortar placement, which affects the joint height. It can be easily handled by the height adjustment mechanism.
In addition, when stacking the entire concrete block so that it matches the predetermined planned height, such as a partition wall, the number of steps of the concrete block and the height of the joints are assigned in advance, and the basic transverse block If the height adjustment mechanism in the direction of the short side of the joint mold is adjusted, there is also an effect that the concrete block can be accumulated easily and accurately.
