Description

Technical Field

[0001] The utility model relates to the field of ECP boards, in particular to an ECP half template and a wall board. Background Art

[0002] Extruded Cement Panel, referred to as ECP board, is a cement product made of silicate cement, fiber, and siliceous materials as the main raw materials, which is formed by vacuum high-pressure extrusion and then cured by steam or autoclave. ECP board is widely used in sound barriers, building curtain walls, building exterior walls, etc. due to its high strength, light weight, fire resistance, weather resistance, earthquake resistance, sound insulation and other excellent properties. Due to the heavy texture and special surface design of ECP board, it has a good decorative effect on buildings and is popular in the market. A large number of production lines were built in China in a short period of time, and relevant standards were formulated.

[0003] The investment in the construction of a production line is huge, often tens of millions or even hundreds of millions. As a result, the investment and equipment depreciation share a large proportion in the cost of the product. In addition, the requirements for material preparation, production process, quality control, etc. during the production process are relatively strict, resulting in high production costs and market prices.

[0004] ECP boards are only used as external decorative boards, and are additional decorative products outside of concrete walls or energy-saving and thermal insulation walls. They are installed on the outside of building walls through dry hanging construction, which leads to excessively high construction costs for the entire wall and great resistance to market sales. Most ECP board manufacturers are in a state of suspension or semi-suspension, resulting in a huge waste of corporate funds and social resources.

[0005] Upgrading and renovating ECP boards, giving full play to the advantages of ECP's high strength and good texture, developing new building materials based on ECP boards, optimizing building wall structures, and reducing the overall construction cost of walls are undoubtedly the only way to make ECP boards regain market recognition. Utility Model Content

[0006] The purpose of the present application is to provide an ECP half formwork and wallboard, aiming to solve the above-mentioned problems in the prior art.

[0007] The embodiment of the present application provides an ECP half template, including an exterior decorative panel, wherein side panels are fixed at both ends of the exterior decorative panel in the height direction, the root of the side panel is connected to the exterior decorative panel, and the end of the side panel extends perpendicularly to the exterior decorative panel, the outer side surface of the side panel is a straight surface, and the inner side surface is an arc surface convex inwardly, so that the thickness of the side panel gradually increases from the root to the end; a plurality of ribs are arranged at equal intervals on the exterior decorative panel between the two side panels, the ribs are parallel to the side panels and the length of the ribs is equal to the length of the side panels, and the thickness of the ribs gradually increases from the root to the end so that the cross-section is trumpet-shaped; a socket and a plug are respectively arranged on the outer sides of the two side panels, and the shapes of the socket and the plug are matched to allow plug-in connection.

[0008] Preferably, the spacing between two adjacent ribs is equal to the spacing between an adjacent rib and a side plate, and both spacings are twice the length of the rib.

[0009] Preferably, two ECP half-form ribs are connected in an axisymmetric manner to form a production unit, the cross-section of the rib in a production unit is shuttle-shaped, and the side plates are provided with parallel double sockets or double spigots.

[0010] Preferably, the side plate and the rib plate are provided with incisions colinearly.

[0011] A wall panel comprises the ECP half template; the ECP half template is multiple, and the multiple ECP half templates are spliced ​​and connected through sockets.

[0012] Preferably, the ECP half formwork is used as the bottom formwork, and prefabricated lightweight concrete is fixed inside to form a prefabricated lightweight concrete composite wall panel; the ECP half formwork is used as the outer formwork, and ordinary concrete or lightweight concrete is cast inside to form a cast-in-place concrete wall panel or a cast-in-place lightweight concrete wall panel.

[0014] The beneficial effects of the utility model are:

[0015] 1) The functional characteristics of the ECP board will not be changed, and its decorative function can still be exerted.

[0016] 2) Under the premise that the production capacity of ECP board manufacturers remains unchanged, the decorated wall area has doubled, which reduces the construction cost of using the board for wall construction by nearly 50%.

[0017] 3) It eliminates the external construction operation of the original product, saves the cost of embedded parts, fasteners and other additional accessories and labor costs used in traditional construction, and further reduces the construction cost.

[0018] 4) The installation of ECP decorative panels is synchronized with the wall structure construction and used as the outer formwork of cast-in-place concrete walls or thermal insulation composite walls, which reduces the formwork costs and further reduces the construction costs.

[0019] 5) It eliminates the need for layer-by-layer construction of traditional exterior wall insulation or other forms of insulation panels and the complicated operation of separate external decorative panels, resulting in lower construction costs and better construction effects.

[0020] 6) The thermal insulation and building structure are integrated to make the wall more integrated and durable.

[0021] 7) Completely avoid the phenomenon of cracking of the outer protective layer, and falling off of the protective layer and the thermal insulation layer of the traditional external thermal insulation energy-saving wall.

[0022] 8) The insulation layer is naturally divided into blocks and enclosed within the wall structure to avoid the occurrence of fire.

[0023] 9) The composite wall does not use any embedded parts, fasteners, etc., avoiding quality problems caused by rust and looseness of related accessories. BRIEF DESCRIPTION OF THE DRAWINGS
