Abstract

PURPOSE:To uniform precision of height of a concrete block, to obviate the need for a skilled worker in execution and to perform dry masonry or assembly execution using an adhesive by supplying curable material such as cement powder and mortar on the upper surface of the concrete block, rolling and molding it by a rolling device so that the height of the concrete block is regulated to constant dimension. CONSTITUTION:Curable material 12 is properly extruded to a knock pin 15 and supplied to the upper surface 3 of a concrete block 1 according to actuation of a vibration motor 16 and provided while it is cut in the tip of a feed port 9. Then the concrete block 1 reaches a rolling device B. Double side parts of a wear plate 2 are pushed by a pushing roller 11. Furthermore the upper surface 3 of the concrete block 1 is pushed by both the pushing roller 11 and a roller 10 for rolling wherein the dimension of height has been regulated and set. Thereby the height of the concrete block 1 is corrected to a required dimension.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a height correction device for concrete blocks that can easily keep the height constant, especially in the case of masonry.

[Conventional technology] Concrete blocks, especially hollow concrete blocks, are mostly made using concrete block molding machines, but the type of aggregate, mixing state of materials, kneading,
The condition of the molding changes depending on the material supplied to the formwork, the method of filling, etc., and it may be said that it is impossible to obtain a concrete block that always has a constant height. For this reason, the standards allow a certain degree of dimensional tolerance, and in reality, during the masonry construction stage, skilled workers adjust the joint mortar to compensate for uneven block heights. Therefore, the amount of concrete block masonry work per day is reduced.

On the other hand, grinding or cutting the top surface of tall concrete blocks has been done to make the height uniform, but this is quite expensive, and it is also difficult to adjust the blades used and treat sewage. There are many problems such as the need to consider the following.

Problems to be Solved by the Invention] The present invention aims to uniformize height accuracy continuously at the same time as forming without requiring cutting or grinding of concrete blocks after forming, and requires skilled workers to perform construction. The purpose of the present invention is to provide a concrete block that enables empty stacking or masonry construction using an adhesive without the need for concrete blocks.

[Means for Solving the Problems] The present invention provides a hardening material supply device for height adjustment for concrete blocks on a conveyor for conveying concrete blocks molded by a molding machine and demolded onto a receiving plate. This is a concrete block height straightening apparatus characterized in that a rolling device for the supplied hardenable material is sequentially provided.

In other words, even if the dimensions of a concrete block molded by a concrete block molding machine are within the allowable range of the Japanese Industrial Standards, it is inevitable that the concrete blocks will be uneven. It is intended to obtain high precision products within. As the hardenable material, cement powder, mixed powder of cement and various admixtures, or cement mortar is used.

[Function] A hardenable material supply device for height adjustment supplies hardenable materials such as cement powder or mortar to the top surface of the concrete block, and a rolling device applies hardenable materials such as cement powder or mortar so that the height of the concrete block becomes a constant dimension. Roll and form.

[Example] Examples will be described based on the drawings.

FIG. 1 is a plan view of the present invention, and FIG. 2 is a front view. In the figure, C is a concrete block molding machine that molds concrete blocks by vibration and pressure, and the product concrete block l is placed on a receiving plate and carried out by a conveyor 4. A height-adjusting curable material supply device A and a rolling device B are sequentially provided on the conveyor 4.

FIG. 3 is a plan view of the height-adjusting curable material supply device A and rolling device B, and FIG. 4 is a front view thereof. A suitable number of product concrete blocks 1 (four in the figure) are placed on the receiving plate 2, conveyed by the conveyor 4, and delivered to the lower part of the height-adjusting curable material supply device A. The device A has a hopper 5, a stirring blade 6 at the bottom of the hopper, a supply tank 7, and a supply head 8, and supplies a predetermined amount of hardenable material from a supply port 9 to the upper surface 3 of a concrete block 1.

Concrete block l then reaches rolling mill B. The device B has a rolling roller 10, and also has a receiving plate 2.
It has a presser roller 11 that presses both sides of.

FIGS. 5 to 7 are diagrams for explaining aspects of the present device in more detail. The curable material 12 is put into the hopper 5, and is fed into the supply tank 7 while being stirred by the stirring blade 6. Within the supply tank 7, it is further stirred by the stirring blade 13 and sent into the supply head 8. A pneumatic cylinder 14 is attached to the supply head 8, and a knock bottle 15 is disposed inside the supply head 8, and the curable material 12 is appropriately pushed out from the supply port 9 into the knock bottle 15, and the vibration motor 1B is operated. Accordingly, it is supplied to the upper surface 3 of the concrete block 1. Assuming that the height of the concrete block is H, the curable material 12 is placed thereon while being scraped at the tip of the supply port 9.

FIG. 6 is a diagram illustrating the details of supplying the curable material 12, in which the supply ports 9 at the bottom of the supply head 8 are provided in the same number as the number of parts required for raising the concrete block l, and the pneumatic cylinders 14 and knock bottles 15 are provided. The number also corresponds to this.

The supply head 8 is replaceable with respect to the supply tank 7 since the shape of the supply port 9 needs to be changed depending on the form of the target concrete block 1. At this time, in order to increase the effectiveness of vibration, the frame 18 is attached via an elastic body 17.

Then, the concrete block l, on which the hardening material 12 for height adjustment is placed on the upper surface 3, reaches the rolling mill WIB,
While pressing both sides of the receiving plate 2 with the press rollers 11,
The upper surface 3 of the concrete block 1 is held by the pressing roller 11 and the rolling roller 11 whose height has been adjusted.
to correct the height of the concrete block 1 to the desired dimension H'. Furthermore, since the concrete block 1 moves on the conveyor 4 together with the receiving plate 2, the rolling roller 10 is attached to the main body frame 20 with an elastic body 19 so as to absorb vibrations.

[Effects of the Invention] As described above, according to the present invention, a concrete block having a height H with varying dimensions can be corrected to a regular dimension H' with high precision.

Therefore, it is possible to solve the problem that conventional concrete block masonry requires skill.
