Detailed Description
The invention is further described with reference to the accompanying drawings and specific examples:
the invention relates to a wall body integrally formed by a disassembly-free template, which is shown in fig. 1 and 2, and comprises a vertical main body structural member 101 and a filling wall section 102, wherein the vertical main body structural member 101 comprises a member template 1 and a member pouring layer 2 fixedly poured with the member template 1, the filling wall section 102 comprises a filling template 3 and a filling pouring layer 4 fixedly poured with the filling template 3, the filling template 3 comprises a plate body 5 and a filling block 6 arranged on the back surface of the plate body 5, and the member pouring layer 2 and the filling pouring layer 4 are integrally poured and formed.
According to the invention, the integrally formed wall body is supported by the component templates 1 and the filling templates 3 together by means of supporting, so that a casting cavity formed by connecting the vertical main body structural component 101 and the filling wall section 102 into a whole is formed, and the component casting layer 2 and the filling casting layer 4 are integrally cast and formed, wherein the component templates 1 and the plate body 5 are made of the same material, the component casting layer 2 is a casting layer which is positioned on the vertical main body structural component 101 and is used for bonding the component templates 1, the filling casting layer is a casting layer which is positioned on the filling wall section 102 and is used for bonding the filling templates 3, the thickness of the component casting layer 2 is larger than that of the filling casting layer 4, and the filling blocks 6 arranged on the filling templates 3 play a role in reducing the thickness of the casting layer of the filling wall section 102, so that casting materials are reduced, meanwhile, the weight of the filling wall section 102 is further reduced by means of the filling blocks 6 made of lightweight aggregate concrete or other lighter materials such as foam plates and the like, and the set component templates 1 and the plate body 5 are made of inorganic fiber compression plates.
In embodiment 2, as shown in fig. 1, adjacent filler blocks 6 in the filler wall section 102 and the plate body 5 together enclose a columnar bump 8 on the filling and pouring layer 4.
The horizontal section of the filling block 6 is in a trapezoid, rectangle or arc structure.
As shown in a filled wall section 102 in fig. 1, in this embodiment, a filling template is symmetrically arranged on two sides, by means of a trapezoidal inclined surface 7 and a plate body 5, a columnar bulge 8 with an octagonal structure is enclosed, and the columnar bulge 8 and a filling pouring layer 4 are integrally poured and formed, so that a column structure with a bearing function is formed on the filled wall section 102, the requirement of self-bearing can be met, meanwhile, better structural strength in later decoration is ensured, in general, by means of the filling template 3, the filling pouring layer 4 structure with alternate width is enclosed, so that weight is reduced, better structural strength is ensured, if a part of filled wall needs to be disassembled during decoration, the residual filled wall section 102 is prevented from being broken and cracked due to the existence of the columnar bulge 8, the development of decoration construction is facilitated, and if the filling block 6 is of a rectangular or arc structure, the columnar bulge 8 is also formed on the filling pouring layer 4, and the higher filling pouring layer 4 is ensured to have good stability.
Because the castable material adopts concrete and other materials to shrink when being solidified, the columnar bulge part 8 also shrinks, the shrinkage direction points to the internal centroid of the columnar bulge part 8, and the plate body 5 and the filling block 6 adhered to the outer side of the columnar bulge part 8 shrink along with the shrinkage direction, so that the effect of tightening the wallboard gap after the wall body is solidified is formed.
In embodiment 3, as shown in fig. 3, the component template 1 and/or the plate body of the filling template 3 are provided with an anti-falling structure, and the anti-falling structure comprises a bolt 9 and an anti-falling part arranged on the bolt 9.
The anti-falling structure arranged on the component template 1 and/or the filling template 3 ensures that the component template and a pouring layer formed by a pouring body form a solid connection, so that the wallboard is prevented from falling off when the pouring layer is solidified and dried, and the integrity of the wall is ensured.
Further, the anti-falling part is a thread structure arranged on the rod body of the bolt rod 9 or an anti-falling block 10 fixed with the bolt rod 9, and is buried in the component pouring layer 2 or the filling pouring layer 4.
The anti-drop part is arranged at the edge part of the plate body, as shown in fig. 3, so that the edge of the plate body is prevented from being separated from a pouring layer in the wall, and meanwhile, as shown in fig. 1, a plurality of groups of anti-drop structures are arranged in a matrix. The anti-drop part is positioned at the edge of the plate body, and is just the position of the columnar bulge part 8, so that the joint of the filling wall section 102 is tighter by means of the shrinkage phenomenon of the columnar bulge part 8, and the wall surface finish is improved.
Further, a bolt cap 11 is fixed on the rod body of the bolt rod 9, and a counter bore 12 for accommodating the bolt cap 11 is arranged on the component template 1 and/or the plate body of the filling template 3. The bolt cap 11 is positioned in the counter bore 12, so that the protruding bolt cap 11 does not exist on the wall surface, the counter bore 12 is only required to be plugged in later-stage wall surface construction, and the construction is simple and convenient.
A construction process of a form-free integrally formed wall body comprises the following steps,
a. prefabricating the finished component template 1 in a factory, and preparing a filling template 3 with a plate body 5 and a filling block 6 structure on the back by a one-time pouring or bonding mode;
b. supporting and enclosing the component template 1 and the filling template 3 on a construction site to form a pouring cavity;
c. pouring concrete into the pouring cavity, forming an integral pouring layer after solidification, wherein the pouring layer is divided into a component pouring layer 2 and a filling pouring layer 4 according to the adhered wallboard, the wall corresponding to the component pouring layer 2 is a vertical main body structural component 101, and the wall corresponding to the filling pouring layer 4 is a filling wall section 102;
d. the component template 1 and the filling template 3 are used as permanent templates to be remained in the wall body, and the support is removed, thus completing the construction of the integrally formed wall body.
Based on the construction process, when the wall body is integrally formed by the prefabricated component template 1 and the filling template 3, the prefabricated component template 1 and the filling template 3 are used as permanent templates, the template is not required to be disassembled after construction, the surface of the wall body is smooth and clean, a casting cavity is built according to design requirements, the casting cavity is filled, meanwhile, the construction of the component casting layer 2 and the filling casting layer 4 is completed, the component casting layer 2 and the filling casting layer 4 are simultaneously constructed by adopting the same material, the wall body is good in integrity and high in wall body quality, and the problems that in the prior art, the later-stage smooth construction amount of the wall body is large and the wall surface is easy to crack are effectively solved.
