Definitions
- the present invention relates to a precast concrete stair block used for on-site strike of stairs and a stair construction method using the same.
- the target sloped surface is pressed flat, and foundation concrete with reinforcements is struck along the slope, and each stairs of stairs is formed with foundation concrete on foundation concrete.
- the conventional method is to finish the surface with mortar (see Figure 4).
- the above-mentioned conventional construction method is not suitable for construction at a time when the temperature difference is extremely large, and particularly in a region where freezing occurs.
- Patent Document 1 Registered Utility Model No. 3045821
- the step block according to the above-mentioned known technology is too heavy to be manually transported and installed, and adjacent blocks are easily displaced between the underlying concrete surface and the back of this step block. There are some problems such as peeling off due to the expansion of residual air and intruding water, which easily forms gaps.
- the problem to be solved by the present invention is to overcome the problems with the step block according to the above-mentioned known technology and to reduce the weight so that it can be manually transported and installed, blocks adjacent to each other after construction There is no gap between them and that the block is not lifted up or peeled off due to heat or cold.
- the above problem is achieved by forming a large depression on the back surface of the block to achieve a light weight chair, and forming a radius (a partial cylindrical concave surface) of a predetermined radius at the inside corner of the depression on the back surface.
- the stair block is designed to prevent the formation of sharp edges that interfere with the filling of the stair block, the stair block has slippage prevention grooves formed on the sides of the block to bond adjacent blocks together with a mortar, and It can be solved S by the step block which made a hollow and made a light weight.
- the product with a length of 330 mm falls within a weight range which can be carried manually by about 26 kg. This is a great advantage for construction on slopes where heavy equipment is difficult to enter.
- the mortar to be laid under the block is filled up to every corner of the recess space and does not form a cavity.
- a preparatory process for striking the finish target slope flatly, determining the number of steps, the kicking height, and striking the finished surface
- Seventh step Completely lay in by using a plywood board or the like to firmly penetrate the ridge between adjacent stair blocks.
- FIG. 1 is a perspective view, a plan view, an elevation view, a back view, a side view, a cross-sectional view and a rear view, illustrating the shape of a step block as one embodiment of the present invention
- FIG. I a perspective view of the stair block
- Fig. B is a plan view
- Fig. C is an elevation view
- Fig. D is a back view
- Fig. E is a side view
- Fig. F is a-a sectional view
- Fig. G is a rear view.
- the symbol a-a in FIG. 1A indicates the position of the cutting plane shown in FIG. 1F.
- Reference numeral 1 in FIG. 1 is a kicking surface
- 2 is a depression in the front center of the kicking surface
- 3 is a chamfer between the tread surface and the kicking surface
- 4 is a tread surface
- 5 is a side surface
- 6 is a The anti-slip groove 7, the anti-slip groove 7, the back 8, the recess 9 on the back, and the rounded portion 10 in the recess on the back 10 are shown.
- FIG. 2 is a cross-sectional view showing the overall structure of a staircase constructed using the staircase block shown in FIG. A mortar is laid on a foundation made of reinforced concrete and a stair block force S is placed on it.
- FIG. 3 (1) One (9) is a diagram showing an example of dimensions of each part.
- the length of the main dimension line ag entered in the perspective view in Fig. 3 (1) is shown on the table, and the dimensions of the other details are shown in each partial view (2) to (9).
- Fig. 3 (2) shows the tread surface 4, 4 the same (3) shows the kicking surface 1, 4 the same (4) shows the back 8 the same (5) 1 (7) shows the side 5 and the same (8)
- the same reference numeral (9) of the locking groove 7 is a view showing respective portions of the rear surface.
- the present invention relates to a step block which is a type of material used for the construction work of stairs in a residential area etc. Therefore, the promotion and development of many related industries such as the concrete product manufacturing industry and the civil engineering and construction industry. It is expected to contribute to Brief description of the drawings
- FIG. 1 is a perspective view, a plan view, an elevation view, a back view, a side view, a cross-sectional view and a rear view for explaining the shape of a step block as one embodiment of the present invention.
- FIG. 2 is a cross-sectional view of a prefabricated staircase for illustrating the installation state of the staircase block as the present embodiment.
- FIG. 3 is a diagram showing an example of the dimensions of each step block according to the present embodiment.
- FIG. 4 A conceptual diagram for explaining a conventional stair construction method.
- FIG. 5 A conceptual view for explaining another conventional stair construction method.
