In the field of buildings, at present, most of load-bearing walls and non-load-bearing walls are brick wall structures, namely, the load-bearing walls and the non-load-bearing walls are built by bricks. In particular to a partition wall which plays a role in partition in a house, in the construction process, after the main body of the wall is built by bricks, the wall surface is coated by concrete on the two sides of the wall body. The traditional wall structure and the construction method have certain problems: firstly, the construction efficiency is low due to the complex construction steps; secondly, more building materials are used; thirdly, the sound insulation and heat insulation effects of the constructed wall are poor.
The light concrete is prepared by filling light materials such as foamed concrete, perlite, fly ash, polyphenyl granules or expanded vermiculite and the like. In recent years, the use of such concrete materials is actively promoted in the country. Lightweight concrete is widely available in various types, such as foamed concrete and the like. The lightweight concrete has the characteristics of light weight, good heat preservation, strong anti-permeability performance, good fireproof performance, environmental protection and less pollution. The concrete can be applied to the construction of the wall body by using a process such as integral casting or other common concrete processes. In the processes, a steel protecting template serving as a wall mold is mostly required to be supported firstly, then the main body part of the wall is molded and poured, and finally the steel template is removed, so that the surface of the wall is easily damaged in the process of removing the steel template, and in addition, the two sides of the light concrete wall main body are plastered to form a wall surface after removing the steel template. The construction scheme has the problems of complex steps, low construction efficiency and high construction cost, and the wall surface plastered twice is easy to fall off.
In addition, the applicant discloses a cast-in-place lightweight composite wall body in the prior Chinese patent application 200610046965X, which comprises a wall surface and a lightweight concrete interlayer, wherein the wall surface is formed by splicing prefabricated wall panels on two sides, and the lightweight concrete interlayer is arranged between the prefabricated wall panels. And 4-6 mm exhaust gaps are reserved between the assembled prefabricated wall panels. In order to arrange a door or a window on a wall body, a blocking plate is blocked at the end part between two opposite prefabricated wall panels around a notch reserved for the door or the window on the wall body, and an exhaust gap of 4-6 mm is reserved between the blocking plate and the prefabricated wall panels. The prefabricated wall panel comprises a panel surface and splicing units, wherein the outer edges of the panel surface are used for splicing adjacent prefabricated wall panels, and the splicing units are of tenon-and-mortise structures and tenon-and-mortise structures which are matched with each other; or the outer edges of the board surfaces are flat structures which are matched with each other, and 4-6 mm exhaust gaps are reserved during assembly.
The cast-in-place light composite wall in the application is not only complicated in construction method, but also has certain problems in the internal strength of the wall.
Disclosure of Invention
Aiming at the problems, particularly the problems of complex construction method and weak strength of the prior application 200610046965X cast-in-place light composite wall, the invention provides an anti-expansion component which is mainly used in the construction process of improving the cast-in-place light composite wall. The problem that the wall body is deformed due to the expansion of concrete in the wall body adopting the pouring mode can be effectively solved.
In order to solve the problems, the invention provides an anti-expansion assembly for building a cast-in-place lightweight composite wall body. The expansion-proof die comprises a net-shaped structure which is positioned in a plane and is made of plate-shaped or rod-shaped materials, and a frame body or a plate rib for increasing the strength of the net-shaped structure and preventing deformation; the positioning penetrating fixing piece comprises a bar for penetrating through the wall body and a pressing block connected with the two ends of the bar through threads.
In a using state, the anti-expansion die is fixed on two sides of the wall by positioning the press blocks penetrating through the fixing piece, and at the moment, the length of the bar between the press blocks is constantly equal to the sum of the thickness of the wall and the thickness of the die frame bodies on two sides.
Through the technical scheme, the anti-expansion assembly for building the cast-in-place light composite wall can be used in the building process of the cast-in-place light composite wall, can effectively improve the building efficiency of the wall, and particularly can effectively prevent the problem of wall expansion cracking after concrete is poured. Therefore, the anti-expansion assembly has the characteristics of practicability, easy use and good effect.

Detailed Description
For the purpose of illustrating the invention, the dimensions of the various elements in the drawings are to be understood as differing from the actual dimensions.
As shown in fig. 3, the applicant provides a cast-in-place composite wall, which comprises a wall surface formed by splicing prefabricated wall panels 1 at two sides, and a lightweight concrete interlayer 8 between the prefabricated wall panels 1. In order to ensure the distance between the prefabricated wall panels at the two sides and simultaneously strengthen the strength of the wall body, the light steel keels 12 are arranged between the prefabricated wall panels 1 at intervals, so that the wall body is convenient to construct. Preferably, the light gauge steel is supported between the floor and the ceiling. Of course, the support structure can also be transversely arranged and supported between the walls 5 or the upright posts which are bordered on two sides according to the requirement. In order to fix the light steel keel, the end part is provided with a bolt hole. As shown in fig. 2, the light steel keel is fixed by connecting a beam or keel 15 fixed on the ceiling 2 and the ground 3. As shown in fig. 4, the light steel keel is cut off relative to the matching state of the two prefabricated wall panels and the light steel keel, and the height of the light steel keel is actually the same as the height of the whole wall.

As shown in fig. 5, the expansion-preventing die 42 includes a net structure 43 made of a plate-like or rod-like material and located in a plane, and a frame body or a plate rib 44 for increasing the strength of the net structure and preventing deformation; preferably, a plate-shaped steel material is used, and the positioning penetration fixture 41 shown in fig. 8 includes a bar material for penetrating the wall and a pressing block 13 connected to both ends of the bar material by a screw thread.
In use, the anti-bulging die 42 is first applied against a prefabricated wall surface, as shown in fig. 7. Next, as shown in fig. 6 and described with reference to fig. 1, a hole is made in the wall surface, a positioning penetration fixture 41 is penetrated through the wall surface, and the fixing is achieved by the nut and the screw 14 at the end of the rod. At this moment, briquetting 13 will prevent that the mould that expands from fixing in the wall both sides, and rod length between the briquetting is the identical with wall body thickness and both sides mould support body thickness sum to guarantee the planarization of wall body and the uniformity of wall body thickness, can realize through setting up the location boss or adding the holding ring of establishing at the rod tip. And finally, after the concrete poured in the wall body is solidified, the expansion-preventing component is detached.
