Description

Concrete working seam isolation method

The invention relates to a concrete working seam isolation method, in particular to a concrete working seam isolation method using an elastic structure.

Traditionally, in the case of partitioning concrete, it is generally divided into a first pouring structure and a rear pouring structure. When applied as a pre-sprayed structure, angles or mesh materials are usually used as the occlusion treatment.

However, the use of angles or mesh materials can make the construction joints between the two structures more uneven and prone to leakage. After removing the angle or mesh, the uneven area also takes time to clean up.

In view of this, an embodiment of the present invention provides a concrete working seam isolation method, comprising the steps of: (S10) forming a pouring space, wherein the pouring space comprises a plurality of meshes; (S11) at least partially continuous mesh The elastic structures are respectively placed in the cells, and the elastic structures are at least partially in contact with each other side by side; (S12) a first pouring operation is performed on one side of the elastic structure to complete the first pouring structure; (S13) the elastic structure is removed; and (S14) The post-casting operation is performed to complete the post-placement structure, so that the pre-pour structure and the post-pour structure are complementary to the main structure.

In the following, a plurality of embodiments of the present invention will be disclosed in the accompanying drawings. For the purpose of clarity, the details of the invention are described in the following description. However, it should be understood that these practical details are not intended to limit the invention. In addition, some of the known structures and elements are illustrated in the drawings in a simplified schematic representation.

The concrete working seam isolation method of the present embodiment can be applied to all building structures generally referred to as a first pouring structure and a rear pouring structure.

Please refer to FIG. 1 for a flow chart, and please refer to FIG. 2A and FIG. 2B for a schematic view. FIG. 2B is a side view of the structure of FIG. 2A. Step (S10): forming a pouring space, wherein the pouring space comprises a plurality of meshes; and step (S11): respectively placing the elastic knots in at least partially consecutive meshes And the elastic structures are at least partially in contact with each other side by side. For example, as shown in FIG. 2A and FIG. 2B, in the floor space for the floor slab construction, the floor slab 11 is provided with reinforcing bars 12 which are staggered to form a plurality of meshes. The space it sets can be defined as the space. Also, the elastic structure 13 is inserted into the mesh. In detail, the elastic structure 13 is inserted into each of the partially continuous meshes. As shown, the elastic structure 13 is a plurality of columnar bodies standing side by side on the floor mold 11 of the floor.

The elastic structure 13 is, for example, a sponge, a foam or the like having similar elements that are compressible and shapeable. The shape may be a column, a cubic column or a columnar body of other shapes, and is not particularly limited. Preferably, a plastic bag body (not shown) may be coated on the outside to form the elastic structure 13, but not limited thereto, which is intended to prevent the concrete from penetrating into the elastic structure 13.

By virtue of its compressible and deformable characteristics, the elastic structure 13 can be easily inserted into the space enclosed by the steel bar 12 and expanded or filled beyond the remaining space after being inserted. Therefore, the elastic structures 13 are likely to contact each other. Specifically, after the elastic structure 13 protrudes into the mesh, the volume rebounds to a portion of the elastic structure 13 that protrudes out of the mesh, and the cross-sectional area thereof is larger than the cross-sectional area of the mesh.

At the same time, the stop portion 14 can be selectively disposed on one side 131 of the elastic structure 13. In the embodiment, the stop portion 14 is exemplified by an angle material having a cross-sectional area of about 6× ⁶ cm ² , but not limit. It should be noted that in the present embodiment, the height/depth of the concrete to be poured is lower due to the application of the floor slab. Therefore, the size of the elastic structure 13 does not need to be too high to stand upright and secure in the space surrounded by the reinforcing bars 12. In short, the elastic structure 13 of the present embodiment and the extending direction of the stopper portion 14 are perpendicular to each other.

Please also refer to Figure 1 and Figure 2C. Step (S12) performs a first pouring operation on one side of the elastic structure to complete the first pouring structure. As shown, concrete is poured into one side of the elastic structure 13. If the stop portion 14 is provided, the stop portion 14 is opposite to one side of the elastic structure 13 to be mixed. The concrete is poured, that is, with respect to the elastic structure 13, on the same side as the position where the stopper portion 14 is disposed. After the completion of the pouring, the first pouring structure C1 of the floor is formed.

Please also refer to Figure 1 and Figure 2D. Step (S13): The elastic structure is removed. As shown in the figure, after the concrete is poured, the elastic structure 13 is removed, and if the stopper portion 14 is provided, it is removed. Preferably, the timing is when the concrete is initially set. Thereby, it is possible to prevent the concrete from being completely solidified, so that the elastic structure 13 and the stopper portion 14 are not easily taken out.

Please also refer to Figure 1 and Figure 2E. Step (S14): performing a post-casting operation to complete the post-placement structure, so that the pre-pour structure and the post-pour structure are complementary to the main structure. As shown in the figure, the concrete is poured on the side opposite to the side of the first pouring structure C1, and after the concrete is solidified, the rear pouring structure C2 of the floor is formed. The first pouring structure C1 and the rear pouring structure C2 become the main structure of the floor.

According to this design, the construction joint between the two structures C1 and C2 is not easy to leak, and the flatness can be improved. In addition, the elastic structure 13 can be recycled and reused repeatedly, which can reduce the cost of application.

In another embodiment, as shown in FIG. 3, the stop portion 14 preferably includes an angle member 141, an angle 142, and an elevation 143. The angle member 141 is disposed on one side 131 of the elastic structure 13 , and the angle steel 142 is not limited to use an L-shaped angle steel (the cross-sectional area is 3× ³ cm ² , but not limited thereto), and is disposed on one side of the angle member 141 away from the elastic structure 13 and located at The top of the elevation 143. It should be noted that the angle steel 142 may or may not be in contact with the angle member 141 without particular limitation. The elevation 143 is mainly erected on the template 11, and the upper angle 142 is favorable as a reference for the grouting height, avoiding insufficient or excessive grouting height, and forming a wedge at the first pouring structure. It should be noted that the structure of the present embodiment can also be applied to the foregoing construction method, and the application procedure is the same as that of the foregoing embodiment, and will not be further described herein.

The space it sets can be defined as the space. Also, the elastic structure 23 is inserted into the mesh. In detail, the elastic structure 23 is inserted into each of the partially continuous meshes. In addition, since the height/depth of the concrete to be poured when the beam is applied is deep, if the elastic structure is inserted in an upright manner, the size may be too long to be difficult to manufacture and difficult to apply. Therefore, as shown, the elastic structure 23 of the present embodiment is a plurality of columnar bodies stacked on the beam bottom mold 21.

The elastic structure 23 is also a sponge, foam or other similar element having a compressible shape. The shape may be a column, a cubic column or a columnar body of other shapes, and is not particularly limited. Preferably, a plastic bag body (not shown) may be coated on the outside to form the elastic structure 23, but not limited thereto, which is intended to prevent the concrete from penetrating into the elastic structure 23.

Therefore, the elastic structures 23 are likely to contact each other. Specifically, after the elastic structure 23 protrudes into the mesh, the volume rebounds to a portion of the elastic structure 23 that protrudes out of the mesh, and the cross-sectional area thereof is larger than the cross-sectional area of the mesh.

At the same time, the stop portion 24 is selectively disposed on one side 231 of the elastic structure 23. In the embodiment, the stop portion 24 is exemplified by an angle material having a cross-sectional area of about 6× ⁶ cm ² , but not limited thereto. . Since the elastic structure 23 of the present embodiment is in the transverse direction, the extending direction of the elastic structure 23 and the stopper portion 24 are parallel to each other.

In addition, due to the deep depth of the concrete poured, the required elastic structure 23 The number has also increased relatively. Therefore, the dam 25 can be selectively provided on the other side of the elastic structure 23. If the stop portion 24 is provided, the dam 25 is provided on the side 232 of the elastic structure 23 opposite to the stop portion 24. Thereby, the stability of the elastic structure 23 after the stable folding can be enhanced.

If the stop portion 24 is provided, the stop portion 24 is poured with concrete on the side opposite to the elastic structure 23, that is, with respect to the elastic structure 23, on the same side as the position where the stopper portion 24 is disposed. After the filling is completed, the first pouring structure C1 of the beam is formed.

Please also refer to Figure 1 and Figure 4D. As shown, the elastic structure 23 and the stop 24, if any, are removed after the concrete is filled. In addition, if additional dams 25 are added, they must be removed. Preferably, the timing is when the concrete is initially set. Thereby, it is possible to prevent the concrete from being completely solidified, so that the elastic structure 23 and the stopper portion 24 are not easily taken out.
