The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used in the present specification includes any and all combinations of one or more of the related listed items.

[0026] The embodiments of the present application disclose a wall pouring formwork structure. Referring to Figure 1 and Figure 2The system includes several inner templates 1 for forming hollow cavities in the cast-in-place wall and several outer templates 2 for forming the outer contour of the cast-in-place wall. The inner templates 1 and outer templates 2 are fixed together by several connectors 3. The inner template 1 includes an insulation layer 11 and a connecting layer 12 disposed outside the insulation layer 11. Adjacent inner templates 1 are bonded together with adhesive. The insulation layer 11 is extruded polystyrene board, the connecting layer 12 is geotextile, and the connecting layer 12 is bonded to the outside of the insulation layer 11. The outer template 2 is made of wood, and the adhesive is silicone sealant. Grooves are provided on both sides of the insulation layer 11, forming a V-shaped groove between two adjacent inner templates 1. Silicone sealant is squeezed into the V-shaped groove to bond adjacent inner templates 1 together, preventing cement from leaking out from the gaps. Extruded polystyrene (XPS) boards possess excellent thermal insulation properties, high strength, durability, and lightweight characteristics, making them widely used in wall insulation. XPS boards have an extremely low thermal conductivity, effectively preventing heat transfer. They also exhibit good waterproof performance, are not prone to water absorption and swelling, and are not susceptible to biological corrosion, resulting in a long service life. Furthermore, XPS boards are lightweight, facilitating transportation and installation. Geotextiles, as non-woven fabrics, have excellent air and water permeability, effectively preventing concrete or mortar from seeping into the XPS board during pouring, protecting it from damage and maintaining its original insulation performance. Geotextiles also enhance the bonding strength between the XPS board and the poured wall, adhering the XPS board more firmly to the wall and preventing it from detaching or shifting due to external forces during use. In addition, geotextiles help distribute the pressure applied during pouring, resulting in more even pressure on the XPS board and preventing deformation or damage caused by excessive localized stress. By combining geotextile with extruded polystyrene board and fixing it to the cast-in-place wall, the stability of the entire wall structure can be improved, especially when subjected to external forces such as wind loads and seismic loads, thus better maintaining the integrity and safety of the wall. After the wall is cast, the inner formwork 1 located in the hollow cavity of the wall does not need to be removed and can directly serve as the insulation layer 11 of the wall. The connecting layer 12 can increase the connection between the insulation layer 11 and the wall, thereby shortening the construction period, saving construction costs, and improving construction efficiency.

[0027] Reference Figure 1 and Figure 2 The connector 3 includes a fixing screw 31, which passes through the inner template 1 and the outer template 2. One end of the fixing screw 31 is threaded with a connecting nut 32, and the other end is fixedly connected to a support plate 33 for pressing against the inner template 1. By passing the fixing screw 31 through the inner template 1 and the outer template 2, the support plate 33 is pressed against the inner template 1. The support plate 33 has a large area, and after the support plate 33 is in close contact with the insulation layer 11 of the inner template 1, the insulation layer 11 is minimized from being damaged.

[0028] Reference Figure 1 and Figure 2, a plurality of sets of supporting members 4 are arranged between the facing inner molds 1, and the supporting members 4 comprise supporting rods 41, fixing rods 42 and adjusting rods 43. One end of the fixing rod 42 is fixedly connected with a connecting screw rod 421, one end of the adjusting rod 43 is rotatably connected with the supporting rod 41, and the other end is provided with an adjusting groove 431 for the connecting screw rod 421 to be screwed into. The supporting plate 33 is provided with a fixing groove 331 for the supporting rod 41 or the fixing rod 42 to be clamped into, and the bottom wall of the fixing groove 331 is fixedly connected with a fixing clamping block 332 with a rectangular cross section. One end of the fixing rod 42 and the supporting rod 41 is provided with a fixing hole 5 for the fixing clamping block 332 to be inserted into. When the supporting member 4 is installed, the fixing rod 42 is first inserted into the fixing groove 331 of one of the supporting plates 33, so that the fixing clamping block 332 in the fixing groove 331 is clamped into the fixing hole 5 on the fixing rod 42, then the adjusting rod 43 is rotated, the connecting screw rod 421 is screwed out of the adjusting groove 431, so that the supporting rod 41 is inserted into the fixing groove 331 on the other supporting plate 33, so that the fixing clamping block 332 is clamped into the fixing hole 5 on the supporting rod 41, then the adjusting rod 43 is continuously rotated until the supporting rod 41 abuts against the supporting plate 33.

[0029] With reference to Figure 1 and Figure 2 , a fastening spring 6 is arranged in the adjusting groove 431, one end of the fastening spring 6 abuts against the connecting screw rod 421, and the other end abuts against the bottom wall of the adjusting groove 431. The fastening spring 6 can provide an abutting force to the connecting screw rod 421, so that the external thread of the connecting screw rod 421 abuts against the internal thread on the inner side wall of the adjusting groove 431, thereby avoiding accidental rotation of the adjusting rod 43.

[0030] With reference to Figure 1 and Figure 2 , a supporting strip 432 is fixedly connected to the outer side wall of the adjusting rod 43 along the length direction of the adjusting rod 43.

The extruded sheet has very low thermal conductivity, which can effectively prevent heat transfer. Meanwhile, the extruded sheet also has good waterproof performance, is not easy to absorb water and expand, and is not easy to be corroded by organisms, and has a long service life. In addition, the extruded sheet is light in weight, and is convenient for transportation and installation. The geotextile is a kind of non-woven fabric, has good air permeability and water permeability, can effectively prevent concrete or mortar and other materials from penetrating into the inside of the extruded sheet during pouring, protect the extruded sheet from being damaged, and maintain the original thermal insulation performance of the extruded sheet. Meanwhile, the geotextile can also enhance the bonding force between the extruded sheet and the poured wall, make the extruded sheet more firmly adhere to the inside of the wall through the adhesion effect, and prevent the extruded sheet from falling off or displacing due to external force during use. In addition, the geotextile can also help to disperse the pressure applied during pouring, so that the pressure on the extruded sheet is more uniform, and the deformation or damage of the extruded sheet due to excessive local stress is avoided. Through the combination of the geotextile and the extruded sheet, and the fixing with the poured wall, the stability of the entire wall structure can be improved, especially when subjected to external forces such as wind load, earthquake load and the like, the integrity and safety of the wall can be better maintained. When the wall pouring is completed, the inner formwork 1 located in the hollow chamber of the wall does not need to be removed, and directly serves as the thermal insulation layer 11 of the wall.
