detailed description

In order to enable those skilled in the art to better understand the solution of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Fig. 1, a kind of interior wall structure provided by the embodiment of the utility model is a prefabricated wall structure, which is used as the interior wall of a building (such as a building) or the wall of an underground building structure such as a pipe gallery. The wall structure specifically includes a first wall 1, a second wall 2 and a plurality of prefabricated supports, and the plurality of prefabricated supports are sandwiched between the first wall 1 and the second wall 2 to Effective support and connection are formed between the wall body 1 and the second wall body 2 . Since the prefabricated support body is prefabricated, only the remaining cast-in-place area 4 between the first wall body 1 and the second wall body 2 except the prefabricated support body needs to be poured during pouring-in-place. space to save pouring time. The prefabricated support body can be prefabricated in the factory, and its quality is easier to control than cast-in-place, and has good strength, which makes the integrity of the inner wall structure better and its strength higher. The prefabricated supports can be arranged in a dislocation in the horizontal direction between the first wall body 1 and the second wall body 2 .

In one embodiment, the prefabricated support body is a point-shaped support body 3 (as shown in Figures 1-3), and the specific shape may be a circular point or a polygonal point. When circular dots are used, the outer contour of the support body 3 can also play a good role in guiding the slurry. A plurality of point supports 3 are distributed in a distributed manner between the first wall body 1 and the second wall body 2, forming a set of prefabricated support body arrays. There are many ways to arrange the point-shaped support bodies 3 in the array, preferably according to a certain symmetrical rule, so that the supporting force of the wall structure is distributed more evenly. In this embodiment, the point-shaped supports 3 are arranged in columns, and each column is composed of a plurality of point-shaped supports 3, and the point-shaped supports 3 between two adjacent columns are arranged in dislocation, because if they are not dislocated Arrangement, in the space between the first wall 1 and the second wall 2, there will be more continuous hollow areas in the horizontal direction. After adopting a dislocation arrangement, it is equivalent to reducing the support body to a certain extent in the vertical direction At the same time, it avoids the increase of the cost caused by the dense arrangement of the support bodies in the same column. For example, in this embodiment, the number of point-shaped supports 3 in the first column on the far left and the number of point-shaped supports 3 in the third column on the far right are four, and the four point-shaped supports 3 are in the same shape. Spaced out. The number of the second row of point-shaped supports 3 in the middle is three, and the position of each second row of point-shaped supports 3 is roughly located between the first row and the third row of point-shaped supports 3 in the horizontal direction The center of the interval position. In this way, the second column of point-shaped support bodies 3 in the middle is equivalent to filling up the hollow area formed in the horizontal direction by the intervals between the support bodies in the first column and the third column to a certain extent. The supporting force is distributed more evenly, and the strength of the wall structure is better improved.

In another embodiment, the prefabricated support body is a columnar support body 5 (as shown in Figures 4-6), and the columnar support body 5 is vertically arranged between the first wall body 1 and the second wall body 2, forming a mutual parallel columns of columnar supports. For example, in this embodiment, there are five columns of columnar supports. The first column on the left, the third column in the middle, and the fifth column on the right all contain two columns of columnar supports 5 arranged at intervals. The second column and the fourth column contain a columnar support body 5 . Preferably, the columnar supports 5 between two adjacent columns can be arranged in a misaligned manner. For example, the columnar supports 5 of the second column and the fourth column in the middle only partially coincide with the supports of the first column, the third column, and the fifth column in the horizontal direction, and the middle part is located in the first column and the fifth column. The position between the two columnar supports 5 is similar to the misplaced arrangement of the point-shaped supports 3. This arrangement is equivalent to filling the supports in the first, third and fifth columns to a certain extent. The hollow area formed by the interval of the body in the horizontal direction. The supporting force is distributed more evenly, and the strength of the wall structure is better improved. In addition, the advantage of the dislocation arrangement of the columnar supports is that the cast-in-place area 4 formed after the dislocation similarly constitutes a curved slurry channel, so that the wall can be connected into a whole at multiple positions in the vertical direction, and the overall strength is higher . However, if the supports are not arranged vertically, such as continuously distributed from top to bottom, leaving only a corresponding gap at a certain position, then the concrete slurry can only place the support on both sides of the support at a specific position. The space is connected, and the strength is slightly lower than that of the misplaced arrangement.

During the concrete pouring process, air bubbles will be generated due to the defects of the material itself or the defects of the pouring process. If these air bubbles cannot be discharged in time, they will remain on the concrete surface. A small amount of air bubbles will affect the beauty of the wall. Air bubbles in the concrete will affect the durability of the concrete, and the concrete also needs to be poured to make the wall form an integral structure. In order to solve this problem, further, the lower end of the columnar support 5 has a diversion structure, which is used to discharge the air bubbles in the concrete and promote the free flow of concrete on both sides of the columnar support, so that the lower part of the wall can form an integral structure. The flow guide structure can be various, for example, the flow guide structure can include two flow guide surfaces 51, and the two flow guide surfaces 51 are formed by extending obliquely upward from the bottom end of the columnar support body 5, so that the columnar Both sides of the support body 5 discharge the air bubbles, the air bubbles are discharged efficiently and the air bubbles flow evenly. In a preferred embodiment, the two guide surfaces 51 extend obliquely upward from the bottom end of the columnar support body 5 with a fixed slope, and the bottom ends of the guide surfaces 51 transition in a sharp manner, forming a broken-line transition line, namely On the whole, the two guide surfaces 51 form a V-shaped structure, so that the effect of air bubble discharge is better. In addition, the diversion surface can also extend upwards on both sides of the columnar support body 5 according to the changing slope, forming a smooth slope, and the position where the two diversion surfaces connect is also smooth, that is, a U-shaped structure is formed, but the diversion effect Not as good as a V-shaped structure. The lower end of the columnar support body 5 located in the bottom area has a distance from the lower edges of the first wall body 1 and the second wall body 2, which is to ensure that the castable can be placed at the bottom of the columnar support body 5 from the space formed by this distance. The circulation on both sides ensures that the poured concrete body forms a whole with higher strength, and prevents the combined column from forming a barrier during concrete pouring, hindering the discharge of air bubbles, thereby ensuring the effect of compactness and waterproofing.

In some other embodiments, the lower end of one of the first wall 1 and the second wall 2 has a distance from the lower end of the other wall to form a gap for supporting template. For example, Fig. 7 and Fig. 8 are another kind of internal wall structure adopting point support body and columnar support body respectively, wherein the lower end of the second wall body 2 is not flush with the lower end of the first wall body 1, but If a part is missing, this part can be used to support formwork 6 to form a complete pouring space. In addition, gaps can also be left at the lower ends of the first wall body 1 and the second wall body 2, and formwork can be supported on both sides.

The above is a detailed introduction to the interior wall structure provided by the utility model. In this paper, specific examples are used to illustrate the principle and implementation of the present utility model, and the descriptions of the above embodiments are only used to help understand the core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made to the utility model, and these improvements and modifications also fall into the protection of the claims of the utility model. within range.
