The template adopts a rectangular disassembly-free template, the main part of the template is a panel (or called template panel) of the template, and a drawknot plate or other auxiliary structures can be involved according to actual needs. After being solidified, the cast-in-place concrete in the wall structure is solidified with the template (panel), the connecting assembly and the like, the template does not need to be dismantled, and the connecting assembly does not need to be dismantled, so that the construction process is obviously simplified, and the production efficiency is improved.
The panel can adopt the lightweight concrete panel of fibre reinforcement or other suitable materials, and the preferred adoption is adapted to the machining and adapts to the panel that people required to the feel of wall, is nonmetal material usually. For example, the panel may be made by mixing wood flour or other biomass fine granular/powdery material as a main raw material or one of the main raw materials with an inorganic material having binding ability, casting the mixture in a mold, and curing the mixture by a suitable method such as natural curing or heat curing to form a corresponding non-metallic plate. Such non-metallic panels are generally lightweight, have suitable strength, do not deform, are suitable for machining such as cutting, punching, and the like, and such panels used in construction in the background of the prior art generally have good flame retardant properties.
The template (or panel) may be generally arranged in a horizontal direction (the length direction is horizontal in use), or may be arranged in a vertical direction (the length direction is vertical in use).
The thickness of the panel should be such as to provide the corresponding strength and installation requirements for finishing or related facilities, structures.
The form on one side may be a plurality of forms arranged in series in the vertical direction (see fig. 1).
The gap between adjacent edges (adjacent transverse edges) of adjacent forms may be completely sealed, incompletely sealed or unsealed.
The seam seal (including a full seal and an incomplete seal) between adjacent edges of adjacent forms may be made in any suitable manner, for example, by taping. Since such a gap is narrow, the tape adhesion is sufficient to secure the sealing strength.
For example, in the same gap, several unsealed short gaps are preferably left as air holes for pouring concrete. When the concrete is poured, air overstocked at the bottom or the corners of the pouring area can overflow through the gaps, and the air in the concrete can also overflow through the gaps in the vibrating process. The design is beneficial to reducing bubbles (pits) on the surface of the wall body and cavities in the wall body.
In order to improve the strength and durability of the connection between the formwork (panel) and the cast-in-place concrete, the formwork can comprise a panel 11, a drawknot plate 12 is arranged on the casting side surface of the panel, and the drawknot plate is fixedly connected with the panel and is attached to the casting side surface of the panel.

The bonding of the drawknot plate (main body part) on the casting side surface of the panel and the embedding and consolidation of the embedded part in the panel can be simultaneously realized, so that the better fixing effect of the drawknot plate on the panel is obtained.
The connecting part and the pouring side surface of the panel are not bonded or weakly bonded, the weak bonding is bonding with weak bonding force, so that an operator can lift the pulling part from the pouring side surface of the panel manually.
The drawknot plate is usually in a strip shape, can be integrally formed by adopting a steel strip with the same width or a strip made of other materials in a pressure processing mode, and has the advantages of convenient processing, good drawknot reliability and high strength.
The drawknot plate can adopt a periodically repeated structure in the extending direction and is formed by sequentially arranging a plurality of structural units, so that the pressure processing operation is convenient and the balance of the drawknot effect is realized. The structure of each structural unit is the same (except that two ends can be cut into incomplete structural units according to actual requirements), and the structural units are provided with drawknot parts and fixed connection structures between the drawknot parts and the panels.
The structural unit can be divided into a first section (or front portion) and a second section (or rear portion).

The rear width of the connecting part can be smaller than the front width, and the side edges are stepped (see fig. 8), so that the consolidation/fixing strength of the pulling part in cast-in-place concrete is higher, the pulling part is easy to bend in the process of lifting the pulling part, and the bending part is positioned at the rear part of the pulling part, thereby facilitating the field operation.
The connecting portion may be provided with a through hole 14 at the center of the front portion thereof, which is not only advantageous for further improving the strength of the tie portion in the cast-in-place concrete but also for lifting/prying the tie portion through the through hole by a tool such as a screwdriver, if necessary.
The second section of the structure unit is arranged between the first sections of any two adjacent structure units, the width of the second section is smaller than that of the first section, folding edges 15 which vertically extend towards the panel side (vertical to the main body part of the drawknot plate or vertical to the surface of the panel) can be arranged at the edges of two sides of the second section, and after the panel is manufactured, the folding edges are fixedly connected in the panel to form an embedded part of the drawknot plate. The folds can be formed in the strip of equal width by pressing, i.e. the second section is narrower than the first section because the corresponding portions of the strip of equal width are formed into the folds which serve as pre-buried portions (see figures 8-10).
The inner end of the hem may be further formed with a second bend 16 (see fig. 10) parallel to the face of the panel to further improve the strength of the attachment/securement of the drawknot panel to the panel.
According to actual needs and convenience in operation, the number of the drawknot plates on the same panel can be multiple, and the drawknot plates are generally vertically arranged (the extending direction in use is vertical), and the intervals between the adjacent drawknot plates are equal or unequal (see fig. 12 and 13).

Before the panel is prepared, a proper release agent is coated on the side surface of the panel of the bonding part to reduce the bonding strength between the bonding part and the panel and ensure that the bonding part and the panel are not bonded or are weakly bonded. Since the panel material is generally different from cast-in-place concrete, and particularly the unique shape/configuration of the aforementioned drawknot portion is used, the provision of the release agent does not substantially interfere with the drawknot action of the drawknot panel.
