[0001] The invention relates to the technical field of building formworks, in particular to an alloy steel formwork. Background Art

[0002] Building formwork is a temporary supporting structure, manufactured according to design requirements, which allows concrete structures and components to be formed according to specified positions and geometric dimensions, maintain their correct positions, and bear the deadweight of the building formwork and external loads acting on it.

[0003] In the prior art, wooden formwork, steel formwork or aluminum alloy formwork is generally used. In actual construction, wooden formwork needs to be replaced after five floors of use due to its own load-bearing limitation, and once it is soaked in water, it will deform and delaminate. Conventional steel formwork has a large dead weight and cannot be easily transported and moved, so it is gradually being eliminated. The welding cost of aluminum alloy formwork is high during construction, and it is difficult to dismantle. If the aluminum alloy formwork is connected by pin connection, the size of the pins is standard size, and the formwork is customized according to the actual needs of the construction, which makes it difficult for the pins to meet the use requirements of formworks of different thicknesses and different corners when connected. In order to meet the national requirements for green, energy-saving, low-carbon, industrialized and other aspects of the construction industry, the present invention provides an alloy steel formwork that can meet multiple repeated turnover uses, is green and pollution-free, and has high overall stability to solve the above problems.

[0008] Furthermore, the panel and the two frames are processed by cold-bending high-strength alloy plates into an integral piece.

[0009] Furthermore, one side of the back side of the vertical rib plate passes through the front sides of three transverse rib plates in sequence, and the outer side of the vertical rib plate is fixedly connected to the outer side of the transverse rib plate.

[0010] Furthermore, the sides of the two frames facing away from each other are concave toward the sides close to each other, and the two concave parts of the two adjacent frames are combined into a mounting cavity.

[0011] Furthermore, the boss is located inside the installation cavity, the interior of the boss is hollow, and both ends are open.

[0012] Furthermore, the end of the pin body passes through the outer sides of two adjacent frames and the interiors of the corresponding two bosses.

[0013] Furthermore, the tops of the two frames at the top of the same panel are bent and flanged toward the side close to each other, and the outer corners of the tops of the frames are arc-shaped.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides an alloy steel template, which has the following beneficial effects:

[0019] 1. The alloy steel formwork, by adding and subtracting the metal elements of the raw materials to roll the steel, makes the material's strength about 3.5 times higher than that of ordinary steel materials.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 to 4 The present invention provides a technical solution: an alloy steel template, comprising a panel 1, two sealing plates 201 are fixed on the top of the panel 1, two frames 202 are arranged on the top of the panel 1, a plurality of bosses 203 are arranged on the opposite sides of the two frames 202, a pin body 204 is penetrated on the inner side of the boss 203, three transverse ribs 301 are fixed between the opposite sides of the two frames 202, two vertical ribs 302 are fixed between the opposite sides of the two sealing plates 201, and two handles 303 are detachably connected between the opposite sides of the two frames 202;

[0028] In the above-mentioned embodiment, by adding and subtracting the metal elements of the raw materials to roll the steel, the strength of the material is about three and a half times higher than that of ordinary steel materials, and it has the characteristics of high strength and high rigidity. The structural design of the template refers to the design specification of the industry aluminum alloy template, so that the template can be compatible with other building templates such as aluminum alloy and used in combination. By bending the panel 1 and the frame 202 as a whole, the connection strength of the panel 1 and the frame 202 is guaranteed; the frame 202 is made into a bending shape, which not only ensures that its strength is greatly increased, but also meets the adaptation with other types of templates; the frame 20 2 The reverse-bending edging design at the top not only increases the strength of the top of the frame 202 and reduces deformation, but also reduces the friction contact area between the frame 202 and the adjacent template when in use. By means of reverse stretching and punching, the strength of the frame 202 is increased and deformation is reduced after reverse stretching. At the same time, the reverse stretching and punching design can form a hollow-shaped boss 203, so that the connecting through hole has a horizontal plane, and the contact area of ​​the pin body 204 when passing through the through hole to connect the template is changed from a point to a surface, so that all standard pins with different axial lengths in stock on the construction market can be used, and have strong compatibility.

[0029] like Figure 1As shown, it should be noted that the panel 1 and the two frames 202 are processed by cold bending of high-strength alloy plates, and the material composition is: C / 0.04, Si / 0.17, MN / 1.46, P / 0.014, S / 0.002, AL / 0.042, Ni / 0.01, and the mechanical properties are: yield strength ≥700; tensile strength ≥700, which can make the panel 1 and the frame 202 integrally formed using high-strength alloy materials, so that the base of the template has greater stability and strength, which is convenient for long-term repeated use. Among them, the handle 303 can be connected between the opposite sides of the two frames 202 by bolt connection. At the same time, the top of the vertical rib 302 is provided with two plug-in grooves for the two handles 303 to be plugged in, and the left and right sides are open, which is convenient for construction personnel to position and install the handle 303, and the handle 303 can be removed after the template is spliced, so that the handle 303 will not cause additional obstruction and influence on the cast concrete.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, in addition, one side of the back side of the vertical rib 302 passes through the front sides of the three transverse ribs 301 in sequence, and the outer side of the vertical rib 302 is fixedly connected to the outer side of the transverse rib 301, so that the transverse rib 301 can cooperate with the vertical rib 302 to support the combined shape of the panel 1 and the frame 202, so as to improve the stability of the entire template. The sides of the two frames 202 facing away from each other are concavely set toward the side close to each other, and the two concave parts of the two adjacent frames 202 are combined into an installation cavity. Through the concave setting, the contact area between the two adjacent frames 202 when they are fitted can be reduced, thereby facilitating the subsequent removal work.

[0031] At the same time, the boss 203 is located inside the installation cavity, the interior of the boss 203 is hollow, and both ends are open, the end of the pin body 204 passes through the outside of the two adjacent frames 202 and the inside of the corresponding two bosses 203, and the two adjacent frames 202 can be plugged and connected through the pin body 204. The tops of the two frames 202 at the top of the same panel 1 are bent and flanged toward the side close to each other, and the outer corners of the top of the frame 202 are arc-shaped, so that the template can be easily disassembled.

[0032] In addition, if Figure 4As shown, the outer side of the pin body 204 is composed of a disc-shaped block, a cylindrical rod and a conical rod. A cylindrical rod is fixed to the bottom of the disc-shaped block, and a conical rod is fixed to the bottom of the cylindrical rod. A limiting hole is opened between the outer sides of the cylindrical rod and the conical rod, and a pin limiting plate is inserted into the inner side of the limiting hole. The outer side of the cylindrical rod fits with the inner side of the boss 203, so that the pin body 204 can be normally inserted between the insides of two adjacent bosses 203, and can meet the use of existing pins on the market, achieving technical versatility.

[0033] It should also be noted that if Figure 1 As shown, a plurality of connecting holes are provided on the opposite sides of the two sealing plates 201, and the portions with the connecting holes on the opposite sides of the two sealing plates 201 are all concavely arranged. Specifically, inner grooves are formed by stamping on the opposite sides of the two sealing plates 201, and the positions of the connecting holes and the inner grooves correspond to each other, so that pins and other connecting parts can be easily inserted, and since the contact surface is small, it is not difficult to disassemble.

[0034] The working principle of the above embodiment is:

[0035] During actual construction, the frames 202 of two adjacent templates are fitted together, and the pin body 204 is driven in to pass through the corresponding two bosses 203, and then the pin is limited by the pin limiting piece adapted to the pin body 204. Under the contact action of the inner side of the boss 203 and the outer cylindrical surface of the pin body 204, the pin body 204 and the template can be stably connected, thereby completing the splicing and assembly of the two adjacent templates. After the templates are spliced ​​according to actual construction needs, concrete can be poured inside. After it solidifies, the pin body 204 is removed. Under the design of the reverse bending edging at the top of the frame 202 and the arc design at the corners, the contact area between the two adjacent frames 202 will not be too large, resulting in the friction force when removing the template being lower than the friction force of the contact between conventional templates, so that it can be easily removed for reuse.

[0036] Compared with the prior art, the alloy steel formwork, by adding and subtracting the metal elements of the raw materials to roll the steel, makes the strength of the material about three and a half times higher than that of ordinary steel materials, and has the characteristics of high strength and high rigidity. The structural design of the formwork refers to the industry aluminum alloy formwork specification design, so that the formwork can be compatible with other building formworks such as aluminum alloys and used in combination. By bending the panel 1 and the frame 202 as a whole, the connection strength of the panel 1 and the frame 202 is guaranteed; the frame 202 is made into a bending shape, which not only ensures that its strength is greatly increased, but also meets the compatibility with other types of formworks; the reverse bending edging design of the top of the frame 202 not only increases the strength of the top of the frame 202 and reduces deformation, but also reduces the friction contact surface between it and the adjacent formwork when used, making it easier to demold during construction. It is simpler and easier at the same time. This approach breaks the traditional thinking and uses revolutionary innovative design to further reduce labor intensity and improve product quality while maintaining the original functionality, so that the product can meet the needs of multiple recycling uses. Through the reverse stretching and punching method, the strength of the frame 202 is increased and deformation is reduced after reverse stretching; at the same time, the reverse stretching and punching design can form a hollow-shaped boss 203, so that the connected through hole has a horizontal plane, and the contact area of ​​the pin body 204 when passing through the through hole to connect the template is changed from a point to a surface, so that all standard pins with different axial lengths in the construction market can be used, with strong compatibility, avoiding the idleness and waste of a large amount of social resources, and solving the problems of existing construction templates being either low in strength or difficult to disassemble and assemble.
