Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

Specific Embodiment 1, as shown in Figures 1 and 2, the present invention is a formwork-free one-piece wall, including a vertical main structural component 101 and a filling wall section 102. The vertical main structural component 101 includes The component formwork 1 and the component pouring layer 2 are poured and fixed with the component formwork 1. The filling wall section 102 includes the filling formwork 3 and the filling pouring layer 4 that is poured and fixed with the filling formwork 3. The filling formwork 3 includes a plate body 5 And the filling block 6 provided on the back side of the plate body 5, the component pouring layer 2 and the filling pouring layer 4 are integrally cast and formed.

The one-piece wall without dismantling the formwork of the present invention is supported by the component formwork 1 and the filling formwork 3 with the help of support, forming an integrated pouring cavity where the vertical main structural component 101 and the filling wall section 102 are connected, so that the component pouring layer 2 is integrally poured with the filling pouring layer 4, in which the component formwork 1 is made of the same material as the plate body 5. The component pouring layer 2 is a pouring layer located in the vertical main structural component 101 for bonding the component formwork 1. The filling pouring layer is The thickness of the component pouring layer 2 is greater than that of the filling pouring layer 4, and the filling block 6 provided on the filling formwork 3 plays a role in controlling the thickness of the pouring layer of the filling wall section 102. The reduction effect reduces the pouring materials. At the same time, the weight of the filled wall section 102 is further reduced and its thermal insulation performance is improved with the help of the filling blocks 6 made of lightweight aggregate concrete or other lighter materials such as foam boards. The component formwork is set 1 and the board body 5 are made of inorganic fiber compressed boards, which have the advantages of fire resistance and mildew resistance and good surface smoothness. The vertical main structural component 101 and the filling wall section 102 are integrally poured and constructed. The construction speed is fast and the wall integrity is good. , not easy to crack, using permanent formwork to avoid the formwork removal process, easy construction, smooth wall surface, less follow-up processing work on the wall, and greatly reduced costs.

Specific Embodiment 2, as shown in FIG. 1 , the adjacent filling blocks 6 in the filling wall section 102 and the plate body 5 together form a columnar raised portion 8 located on the filling pouring layer 4 .

The horizontal section of the filling block 6 has a trapezoidal, rectangular or arc-shaped structure.

As shown in the filling wall section 102 in Figure 1, this embodiment adopts the method of arranging the filling formwork symmetrically on both sides, and uses the trapezoidal inclined portion 7 and the plate body 5 to form an octagonal columnar bulge 8. The columnar bulge 8 Part 8 and the filling pouring layer 4 are integrally cast and formed, thereby forming a column structure with load-bearing function in the filling wall section 102, which can not only meet the needs of self-bearing, but also ensure better structural strength during later decoration. Generally speaking, , with the help of the filling formwork 3, such a structure of alternating wide and narrow filling pouring layers 4 is formed, which not only helps to reduce the weight, but also ensures better structural strength. If part of the filling wall needs to be dismantled during decoration, the remaining filling wall segments 102 Due to the existence of the columnar raised portion 8, the problem of collapse and cracking of the remaining wall segments is avoided, which facilitates the decoration construction. If the filling block 6 has a rectangular or arc-shaped structure, the columnar raised portion 8 is also formed on the filling pouring layer 4 The columnar structure ensures that the higher filling pouring layer 4 has good stability.

Since the castable materials such as concrete will shrink when solidified, the columnar raised portion 8 will also shrink, and its shrinkage direction points to the internal centroid of the columnar raised portion 8. The plate body 5 and the plate body 5 adhered to the outside of the columnar raised portion 8 The filling block 6 shrinks accordingly, resulting in an effect that the gaps in the wall panels become tighter after the wall is cured.

Specific Embodiment 3, as shown in Figure 3, the plate body of the component formwork 1 and/or the filling formwork 3 is provided with an anti-separation structure. The anti-separation structure includes a bolt rod 9 and is arranged on the bolt rod 9 anti-loss part.

The anti-separation structure provided on the component formwork 1 and/or the filling formwork 3 forms a solid connection with the pouring layer formed by the pouring body, preventing the wall panels from falling off when the pouring layer solidifies and shrinks, and ensures the integrity of the wall.

Furthermore, the anti-separation part is a threaded structure provided on the body of the bolt 9 or an anti-separation block 10 fixed to the bolt 9. The anti-separation part is embedded in the component pouring layer 2 or the filling pouring layer 4. .

The anti-separation part is arranged at the edge of the board body, as shown in Figure 3, to prevent the edge of the board body from being separated from the pouring layer in the wall. At the same time, as shown in Figure 1, the anti-separation structure is arranged in a matrix. There are multiple groups. The anti-separation part is located at the edge of the board body, which is also where the columnar protrusion 8 is located. The shrinkage phenomenon of the columnar protrusion 8 makes the joints of the filled wall segments 102 tighter and improves the smoothness of the wall surface.

Furthermore, a bolt cap 11 is fixed on the rod body of the bolt rod 9 , and the plate body of the component formwork 1 and/or the filling formwork 3 is also provided with a countersunk hole 12 for accommodating the bolt cap 11 . The bolt cap 11 is located in the countersunk hole 12, so that there is no protruding bolt cap 11 on the wall. Later wall construction only needs to fill the countersunk hole 12, and the construction is simple.

a. The component formwork 1 is prefabricated in the factory, and the filling formwork 3 having the structure of the plate body 5 and the filling block 6 on the back is prepared by one-time pouring or bonding;

b. Support the component formwork 1 and the filling formwork 3 at the construction site to form a pouring cavity;

c. Pour concrete into the pouring cavity and form an integral pouring layer after solidification. The pouring layer is divided into component pouring layer 2 and filling pouring layer 4 according to the wall panels to which it is adhered. The wall corresponding to component pouring layer 2 is a vertical main structure. Component 101, the wall corresponding to the filling pouring layer 4 is the filling wall segment 102;

d. The component formwork 1 and the filling formwork 3 are left in the wall as permanent formwork, and the supports are removed to complete the construction of the one-piece wall.

Based on this construction technology, the prefabricated component formwork 1 and the filling formwork 3 are used as permanent formwork when building a one-piece wall without disassembly of formwork. There is no need to disassemble the formwork after construction. The surface of the wall is flat and smooth. A pouring cavity is built according to the design needs, and The pouring cavity is filled, and the construction of the component pouring layer 2 and the filling pouring layer 4 are completed at the same time. Both are constructed with the same material at the same time. The integrity of the wall is good and the quality of the wall is high, which effectively solves the problem of the existing technology. The later leveling construction of the middle wall requires a lot of work and the wall surface is prone to cracking.
