Description

Technical Field

[0001] The utility model belongs to the technical field of templates for buildings, and in particular relates to a high-strength steel frame plastic template and a load-bearing structure containing the template. Background Art

[0002] Aluminum alloy formwork, stainless steel formwork and high-strength alloy formwork have gradually replaced traditional wooden formwork in actual construction, reducing the large number of supporting auxiliary parts such as formwork, package formwork and explosion-proof formwork required in the use of wooden formwork. Please refer to the formwork structure disclosed in patent applications such as CN115030503A and CN219343980U. According to the actual design of the building, a full set of various types of alloy formworks are customized in advance. Before pouring and grouting, various types of alloy formworks are connected into an integral space to be poured through connectors (pins, pins, bolts, etc.). Reinforced concrete structures such as the ground, wall, and floor can be cast at one time, with good molding integrity. The connection of various types of alloy formworks also meets the needs of the transformation of prefabricated buildings. Among various types of alloy templates, there are also many universal templates, such as CN219343980U. In order to facilitate the lateral connection and end connection between templates, the current alloy templates basically have a plate body, a side plate, and an end plate, wherein the plate body and the side plate are mostly integrally bent and formed, and the side plate and the end plate are provided with a number of connecting holes for inserting the connectors at intervals along the length direction. However, in the actual construction process, there are also working conditions where the floor layer does not need to be integrally formed with the ground and the wall during pouring; and the floor layer still has the need for construction standing, and the horizontally laid template is still necessary. At present, the construction method of sealing the floor layer as needed is continued, that is, the universal alloy template laid horizontally. However, if it is only used as a standing support, the use of the existing alloy template will result in material waste; when it is difficult to avoid the occurrence of various materials falling during the construction process, the plate body of the horizontally laid alloy template will also be damaged, and it will need to be re-trimmed or even scrapped after the demoulding is removed in the later stage, which increases the trial cost of the template. The use of the template under this working condition can be further optimized and improved. Summary of the invention

[0022] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] See also Figure 1 , Figure 2The high-strength steel frame plastic formwork of a specific embodiment comprises two parallel and opposite side panels 11 and two parallel and opposite end panels 12; the two side panels 11 and the two end panels 12 are alternately connected end to end to form a rectangular formwork frame 1; the formwork frame 1 is connected with a plurality of transverse reinforcing ribs 4 and longitudinal reinforcing ribs 3 arranged vertically and horizontally, the longitudinal reinforcing ribs 3 correspond to the length direction of the formwork frame 1 and the two ends are respectively fixedly connected to the inner side surface of the end panels 12, the transverse reinforcing ribs 4 correspond to the width direction of the formwork frame 1 and the two ends are respectively fixedly connected to the inner side surface of the side panels 11; a plurality of connection holes 121 are opened through the end panels 12, and the plurality of connection holes 121 are arranged at intervals in the width direction of the formwork frame 1; one side of the formwork frame 1 is a laying plane 13, and the side of the side panels 11, the end panels 12, the transverse reinforcing ribs 4 and the longitudinal reinforcing ribs 3 facing the laying plane 13 are all flush with each other and together form the laying plane 13.

[0024] The high-strength steel frame plastic formwork of the embodiment is a hollow structure, and its manufacturing cost is lower than that of an ordinary mortar-sealing alloy formwork with a plate body. When used as a standing support formwork for a floor layer that does not require mortar sealing, it can be connected between the two keel formworks 6 through the connecting holes 121 of the end panels 12. The laying plane 13 is fully covered with a whole wooden board, which can effectively provide an operating personnel with a standing position, and falling foreign objects will not damage the formwork, and the manufacturing cost and the use and maintenance cost are effectively reduced.

[0025] The side panels 11, the transverse reinforcing ribs 4 and the longitudinal reinforcing ribs 3 are all square tubes, and have the same cross-sectional shape.

[0026] In this way, square tubes of the same specifications are used, which is convenient for unified purchase or manufacturing and management. They can be cut to length and welded as needed during assembly.

[0027] In this embodiment, the square tube is also made by the applicant. The purchased roll-shaped alloy steel plate is unwound by an unwinding machine, connected and continuously rolled by a roller device with a multi-roller group arranged at intervals, and bent and enclosed into a square tube shape. Therefore, the square tube is a square tube formed by welding after bending and enclosing the steel plate. There is only one weld on the square tube, and the side where the weld is located faces away from the laying plane 13. In this way, the flatness of the laying plane 13 can be guaranteed, and it is also easy to identify.

[0028] The end panel 12 is a rectangular steel plate, and the side of the end panel 12 away from the laying plane 13 is higher than the side panel 11. When in use, the uneven side of the end panel 12 higher than the side panel 11 is facing downward, which is more convenient for the operator to identify and lay the laying plane 13 correctly upward.

[0029] In terms of specific dimensions, the cross section of the square tube is rectangular and the thickness is 0.7-2mm, preferably 1.2mm. The width of the square tube is 20mm and the height is 45mm. The thickness of the end panel is 5mm and the height is 50mm. The height direction corresponds to the thickness direction of the template frame. The diameter of the connection hole is 16.5mm, the spacing is 50mm, and the vertical distance from the center of the connection hole to the laying plane is 25mm.

[0030] To ensure the connection strength, the connection holes 121 are flanged holes; an annular gasket 5 is welded and connected to each connection hole 121 one by one on the inner side surface of the end panel 12, and the inner hole of the annular gasket 5 corresponds to and is coaxially arranged with the connection hole 121. The thickness of the annular gasket 5 is 3 mm, so that the connection hole 121 is formed into a flanged hole.

[0031] In this embodiment, the number of the longitudinal reinforcing rib 3 is one, and it is connected between the middle parts of the two end panels 12. The adjacent connection holes 121 on both sides are 50 mm apart from the longitudinal reinforcing rib 3. The longitudinal reinforcing rib 3 and the side panels 11 on both sides are respectively connected with connecting ribs. The connecting ribs on both sides of the longitudinal reinforcing rib 3 are collinear and form the transverse reinforcing rib 4. The number of transverse reinforcing ribs 4 is specifically three. In this embodiment, the middle transverse reinforcing rib is also made of a square tube with a width of 20 mm and a height of 60 mm, and its height direction is set along the length direction of the template frame. The side facing the laying plane 13 still has no weld and is coplanar and flush, so as to improve the connection strength of the middle part.

[0032] During manufacturing, it is first bent and welded into a square tube, and then cut to length according to the design to form a side panel 11, a longitudinal reinforcement rib 3, and a transverse reinforcement rib 4. The end panel 12, an annular gasket 5 and hole positions are laser cut. The annular gasket 5 is welded to the end panel 12, the side panel 11 and the longitudinal reinforcement rib 3 are welded between the two end panels 12, and the transverse reinforcement rib 4 is welded between the side panel 11 and the longitudinal reinforcement rib 3.

[0033] See also Figure 3 The utility model also provides a load-bearing structure, including two keel templates 6 of equal height and parallel spacing, the two ends of the keel template 6 are respectively connected to the top support (not shown in the figure), the top support is connected to the support column, and the side of the keel template 6 is provided with installation holes at intervals along its length direction; it also includes a plurality of the above-mentioned high-strength steel frame plastic templates, each template frame 1 is sequentially arranged between the side surfaces of the two keel templates 6 along the length direction of the keel template 6, Figure 3 Only two pieces are shown in the figure, the end panel 12 is in contact with the side of the keel template 6, the connecting holes 121 correspond to the mounting holes, at least two connecting holes 121 on one end panel 12 are penetrated and fastened to the corresponding mounting holes through the connecting piece 7; the laying planes 13 of each template frame 1 are all facing upward and flush with each other, and each laying plane 13 carries a whole wooden board (not shown in the figure) for standing construction.

[0034] The basic structural form of the load-bearing structure is the same as the existing template assembly, and the end panel 12 is connected to the keel template 6 by pins or bolts, which is also the same as the connection form of the existing ordinary alloy template, which is easy to operate, and the outer sides of adjacent side panels 11 abut against each other without fastening. The beneficial effects of this load-bearing structure are the same as the above effects, which will not be repeated here.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
