Abstract

(57) [Summary] [Purpose] To improve the workability of walls using blocks. [Structure] A supporting projection 5 is provided on a lower surface 3 of a concrete block 1. [Effect] Between the blocks 1 and 1 that are vertically stacked,
A gap is formed corresponding to the height of the supporting protrusions 5, and the mortar 8 can be filled therein. The horizontal height position of the upper block 1 is determined by the supporting projections 5 along the lower block 1.
Moreover, since the upper block 1 is supported by the supporting protrusions 5, the blocks 1 can be stacked further on the upper stage before the mortar 8 is cured.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete block in which a wall body is constructed by stacking upper and lower surfaces and filling a joint material between the stacked upper and lower surfaces.

[0002]

[Prior art]

 Conventionally, this type of concrete block has been widely used for walls such as outer walls of buildings and block walls. For example, a hollow concrete block in which a plurality of hollow portions are vertically installed is known. Then, in the construction using the concrete block, first of all, a plurality of concrete are arranged in the lower stage, and joint materials such as mortar are filled and joined between them, and the second block is superposed on the lower block. At the same time, mortar is filled between the superposed surfaces and bonded, and blocks are sequentially stacked above.

[0003]

[Problems to be solved by the device]

 When constructing blocks as described above, the blocks are stacked so that they are horizontal, and mortar is filled between the upper and lower blocks, so skill is required to arrange the blocks regularly and horizontally. However, there was a problem that it took time and effort. Also, since the mortar is filled in the gap between the upper and lower blocks, the blocks could not be stacked on top of this mortar until it hardened, and the workability was poor.

Therefore, an object of the present invention is to provide a concrete block which can easily obtain the levelness of the block and is excellent in workability.

[0005]

[Means for Solving the Problems]

 The present invention is a concrete block in which upper and lower surfaces are superposed and a wall material is constructed by filling a joint material between the superposed upper and lower surfaces to provide a supporting projection on at least one of the upper and lower surfaces. It is a thing.

[0006]

[Action]

 A gap is formed between the blocks that are stacked vertically, corresponding to the height of the supporting protrusions, and a joint material can be filled in the gap. In addition, since the horizontal height position of the block is determined by the supporting projection, the levelness of the block is obtained and the block is supported by the supporting projection, so that the block is further raised before the joint material hardens. Can be stacked.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 1 to 4 show a first embodiment of the present invention, in which 1 is a concrete block (hereinafter referred to as a block), and this block has a plurality of hollow portions 2 provided vertically. A plurality of supporting projections 5 are provided on the lower surface 4 of the upper and lower surfaces 3 and 4 of the block 2, and the supporting projections 5 include front and rear surfaces 6 and 7 of the block 1 and the cavity portion 2. It is installed at the approximately middle position of. The projection 5 is formed to have a height corresponding to the gap between the upper and lower blocks 1 and 1, and has a substantially rectangular shape in a plane in the length direction of the block. In the figure, numeral 8 is a joint material such as mortar filled between the upper and lower blocks 1 and 1.

Then, as shown in FIGS. 2 and 3, the upper block 1 is superposed on the lower block 1, and in this state, the projection 5 of the lower block 1 is placed on the upper surface 3 of the upper block 1 and the lower block 1 is placed. The upper block 1 is stacked in parallel with the claw 1, and the joint material 8 can be filled in the gap between the protrusions 5. Further, since the upper block 1 is supported by the protrusions 5, the joint material 8 is not crushed even before the joint material 8 is cured, and the upper block 1 can be further stacked to construct the wall body K. it can. Further, FIG. 4 shows the upper and lower blocks 1, 1 superposed in a zigzag manner, and the protrusions 5 of the adjacent blocks 1 on the left and right are placed on the upper surface 3 of the lower block 1.

As described above, in this embodiment, the plurality of blocks 1 are vertically stacked, and the mortar 8, which is a joint material, is filled between the stacked upper and lower surfaces 3 and 4 to construct the wall body K. In the concrete block to be used, since the supporting projections 5 are provided on at least one of the upper and lower surfaces 3 and 4, the height of the supporting projections 5 corresponds to the height between the blocks 1 and 1 that are vertically stacked. As a result, a mortar 8 can be filled here, and since the horizontal height position of the upper block 1 is determined by the supporting projections 5 along the lower block 1, the levelness of the block 1 can be obtained and Since the block 1 is supported by the supporting projections 5, the block 1 can be further stacked on the upper stage before the mortar 8 is hardened, resulting in excellent workability.

Further, as an effect of the embodiment, by providing the protrusion 5 on the inner side apart from the front and rear surfaces 6 and 7, it does not hinder the finishing of the mortar 8 and the protrusion 5 is hidden in the mortar 8. The appearance design is also good. Moreover, since a plurality of protrusions 5, that is, two protrusions 5 are provided in front of and behind the block 1, they can be stacked well even when the blocks 1 are stacked in a zigzag manner as shown in FIG.

It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, as shown in the second embodiment of FIG. 5, the shape of the projection can be appropriately selected, for example, by providing a supporting projection 5A having a trapezoidal sectional shape on the upper surface 3 of the block 1. Also, the number and position of the protrusions can be appropriately selected. Further, protrusions may be provided on the upper and lower surfaces of the block, respectively.

[Effect of device]

 The present invention is a concrete block in which a plurality of blocks are vertically stacked and a wall material is constructed by filling a joint material between the stacked upper and lower surfaces to construct a supporting projection on at least one of the above and lower surfaces. By providing the concrete block, the levelness of the block can be easily obtained, and the concrete block having excellent workability can be provided.
