Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, and in particular to a standardized formwork support tool. Background Technology

[0002] Traditional reinforcement measures for concrete beam formwork systems include under-beam uprights, under-beam horizontal bars, side uprights, double-layered steel pipe main ribs, and tie bolts. While these systems can meet the requirements for new structures, the dense arrangement of the formwork uprights presents challenges in erection. Furthermore, the reinforcement of the beam formwork relies heavily on tie bolts and double-layered steel pipe main ribs, requiring skilled operators; even slight deficiencies in reinforcement can lead to concrete bulging and bursting.

[0003] In renovation and expansion projects, it is often necessary to increase the cross-section of existing concrete structural beams for reinforcement. In such cases, the tie bolts in the traditional beam formwork reinforcement system cannot be installed due to the influence of the original concrete, which is a major pain point in the construction of beam cross-section enlargement reinforcement. Utility Model Content

[0004] The purpose of this utility model is to provide a standardized formwork support tool to solve the problem of difficult tie bolt construction when reinforcing beams with enlarged cross-sections due to the influence of the original concrete structure.

[0005] To solve the above-mentioned technical problems, this utility model provides a standardized formwork support tool, which includes: a horizontal bar, two main ribs, and two main rib diagonal braces. The two main ribs are vertically fixed to the horizontal bar. One end of each main rib diagonal brace is fixedly connected to the end of the corresponding main rib away from the horizontal bar, and the other end is installed on the horizontal bar on the side away from the main rib, so that the two main ribs and the horizontal bar form a U-shaped space, and the main rib diagonal brace, the main ribs, and the horizontal bar together form a right triangle.

[0006] Optionally, in the standardized formwork tool, the crossbar includes two C-shaped channel steels that are joined together, and each C-shaped channel steel has several first holes along its axis on its web.

[0007] Optionally, in the standardized formwork tool, the interval between two adjacent first holes is 5 cm.

[0008] Optionally, in the standardized formwork tool, each main rib includes: a first steel pipe, a second steel pipe, a channel steel end plate, and an ear plate. The channel steel end plate is fastened to the outside of the crossbar. One end of the second steel pipe is vertically fixed to the web of the channel steel end plate, and the other end is sleeved on the outside of one end of the first steel pipe. The ear plate is disposed on the other end of the first steel pipe. A second hole is provided on the ear plate. At least two third holes are provided on the flange of the channel steel end plate, and the interval between two adjacent third holes is the same as the interval between two adjacent first holes.

[0009] Optionally, in the standardized formwork tool, the main rib is vertically fixed to the crossbar based on the cooperation of bolts and nuts.

[0010] Optionally, in the standardized formwork support tool, each main rib diagonal brace includes: a hollow steel pipe, an internal threaded sleeve, a threaded rod, and two ear plates. One end of the internal threaded sleeve is fitted onto the outside of one end of the hollow steel pipe, and the other end is fitted onto the outside of one end of the threaded rod, and can rotate relative to the threaded rod. The other end of the hollow steel pipe and the threaded rod are respectively provided with an ear plate. Each ear plate has a second hole.

[0011] Optionally, in the standardized formwork tool, both ends of each main rib diagonal brace are fixed to the main rib and crossbar respectively based on the cooperation of bolts and nuts.

[0012] Optionally, the standardized formwork tool further includes: several wooden blocks, placed between the main beam and the template and between the crossbar and the template.

[0013] In the standardized formwork support tool provided by this utility model, there is a horizontal bar, two main ribs, and two main rib diagonal braces. The two main ribs are vertically fixed to the horizontal bar. One end of each main rib diagonal brace is fixedly connected to the end of the corresponding main rib furthest from the horizontal bar, and the other end is installed on the horizontal bar furthest from the main rib, so that the two main ribs and the horizontal bar form a U-shaped space. The main rib diagonal brace, the main ribs, and the horizontal bar together form a right triangle. This utility model's formwork support tool adjusts the spacing between the two main ribs according to the size of the enlarged beam cross-section formwork to change the size of the U-shaped space. Based on the U-shaped space and the right triangles on both sides, the column and beam side formwork and bottom formwork can be firmly fixed. The entire formwork reinforcement process does not require tie rods or double-jointed steel pipe main ribs, effectively saving materials. Furthermore, the formwork support tool can be repeatedly reused, is simple to operate, reduces construction costs, improves construction efficiency, and effectively avoids various concrete quality problems.

Detailed Implementation

[0024] The standardized formwork tool proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of a utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In utility models, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.

[0029] Please refer to Figure 1 The standardized formwork support tool includes: a horizontal bar 1, two main ribs 2 and two main rib diagonal braces 3. The two main ribs 2 are vertically fixed to the horizontal bar 1. One end of each main rib diagonal brace 3 is fixedly connected to the end of the corresponding main rib 2 away from the horizontal bar 1, and the other end is installed on the horizontal bar 1 on the side away from the main rib 2, so that the two main ribs 2 and the horizontal bar 1 form a U-shaped space, and the main rib diagonal brace 3, the main ribs 2 and the horizontal bar 1 together form a right triangle.

[0030] like Figure 1 As shown, when reinforcing the beam with an enlarged cross-section, two main ribs 2 are respectively set on both sides of the beam 6 that needs to be enlarged. The distance between the two main ribs 2 can be adjusted according to the size of the beam with an enlarged cross-section template to change the size of the U-shaped space. Based on the U-shaped space and the right triangles on both sides, the column and beam side templates and bottom templates can be firmly fixed. The entire template reinforcement process does not require the installation of tie rods, which effectively saves materials.

[0031] Preferably, the formwork support tool further includes several wooden blocks 7, which are placed between the main beam 2 and the template and the crossbar 1 and the template, thereby transferring the formwork support force of the standardized formwork support tool to the column and beam side templates and the bottom template.

[0032] Please refer to Figure 2 and Figure 3 The crossbar 1 comprises two C-shaped channel steels 8 joined together, each C-shaped channel steel 8 having a plurality of first holes 9 along its axis on its web. In this embodiment, the interval between two adjacent first holes 9 is preferably 5 cm. Using a standardized crossbar 1 instead of a traditional steel pipe, with a first hole 9 every 5 cm on the crossbar, allows for selection of appropriate hole positions according to different beam widths, providing greater flexibility. Simultaneously, the pre-set first holes 9 provide a limit for the main rib 2, ensuring installation accuracy, improving construction efficiency, reducing operational difficulty, and increasing the accuracy of the formwork system.

[0033] Please refer to Figures 4 to 6 Each main rib 2 includes: a first steel pipe 10, a second steel pipe 11, a channel steel end plate 12, and an ear plate 14. The channel steel end plate 12 is fastened to the outside of the crossbar 1. One end of the second steel pipe 11 is vertically fixed to the web of the channel steel end plate 12, and the other end is sleeved on the outside of one end of the first steel pipe 10. The ear plate 14 is disposed on the other end of the first steel pipe 10. A second hole 13 is provided on the ear plate 14. At least two third holes 13 are provided on the flange of the channel steel end plate 12, and the interval between two adjacent third holes 13 is the same as the interval between two adjacent first holes 9. By using two square steel pipes with different cross-sectional dimensions (i.e., the first steel pipe 10 and the second steel pipe 11) to be arranged together to form the main rib 2, the first steel pipe 10 and the second steel pipe 11 can expand and contract relative to each other. Therefore, the appropriate height of the main rib can be freely adjusted according to the beam height, which has great flexibility.

[0034] like Figure 1 and Figure 6 As shown, the main rib 2 is vertically fixed to the crossbar 1 by bolts and nuts 4. Specifically, the bolts pass through the following holes in sequence: the third hole 13 on the main rib 2 → the first hole 9 on the crossbar 1 → the first hole 9 on the crossbar 1 → the third hole 13 on the main rib 2. With the nuts tightened, the main rib 2 and the crossbar 1 are locked and fixed. To accommodate different beam widths (corresponding to the width of the adjustable U-shaped space), the nuts can be loosened and the bolts removed according to the actual width of the supported beam template. The channel steel end plate 12 of the main rib 2 can then slide on the crossbar to adjust the position of the main rib 2 on the crossbar 1, thereby increasing or decreasing the distance between the two main ribs 2. After adjusting to the appropriate position, the bolts and nuts 4 are used to lock and fix it in place.

[0035] Please refer to Figure 7 and Figure 8Each main rib diagonal brace 3 includes: a hollow steel pipe 17, an internally threaded sleeve 16, a threaded rod 15, and two ear plates 14. One end of the internally threaded sleeve 16 is fitted onto the outside of one end of the hollow steel pipe 17, and the other end is fitted onto the outside of one end of the threaded rod 15, and can rotate relative to the threaded rod 15. An ear plate 14 is respectively provided at the other end of the hollow steel pipe 17 and the threaded rod 15; each ear plate 14 has a second hole 13. The main rib diagonal brace 3 is assembled from the threaded rod 15, the internally threaded sleeve 16, and the hollow steel pipe 17, supporting free adjustment of the diagonal brace length and providing great flexibility. Appropriate combinations of main rib and main rib diagonal brace lengths can be selected according to different beam heights and widths, effectively improving the stability of the formwork reinforcement.

[0036] Please continue to refer to this. Figure 1 and Figure 7 Each main rib diagonal brace 3 is fixed to the main rib 2 and the crossbar 1 at both ends by bolts and nuts 4. Specifically, the ear plate 14 at one end of the main rib diagonal brace 3 is set between the two C-shaped channel steels 8 of the crossbar 1. The bolts pass through in the following order: the first hole 9 on the crossbar 1 → the second hole 13 on the ear plate 14 at one end of the main rib diagonal brace 3 → the first hole 9 on the crossbar 1. The main rib diagonal brace 3 is then locked to the crossbar 1 with nuts. Optionally, the ear plate 14 at one end of the main rib diagonal brace 3 can be fixed by a pin to the ear plate at the end of the first steel pipe 10.

[0037] The combination of main rib 2 and main rib diagonal brace 3 to resist the lateral pressure of concrete on the formwork during pouring provides higher stability compared to traditional double-section steel pipe main ribs and tie bolts. Since tie bolts are not used, the problem of not being able to install them in the formwork reinforcement for beams with increased cross-sections is indirectly solved. Furthermore, the absence of tie bolts saves materials and eliminates the need to repair the sleeve holes at the tie bolt locations during later formwork removal.

[0038] Furthermore, the standardized formwork tools of this invention can also be used in new structural engineering projects, which can effectively improve construction efficiency, reduce the operational difficulty for construction workers, and avoid various concrete quality problems.

[0039] It is understood that the above examples are merely examples listed to better understand the technical solutions of the embodiments of this application, and are not intended to be the only limitation on the embodiments.

[0040] Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by this application.

[0041] To better understand the standardized formwork tool of this utility model, the following will be combined with... Figures 1 to 7The main ideas and specific implementation steps of using formwork tools in beam cross-section reinforcement are explained below:

[0042] Step 1: Lay out the lines and position the beams. Based on the positioning, erect the steel pipe uprights 5 on both sides of the beam 6 that needs to be enlarged.

[0043] Step 2: Arrange two C-shaped channel steels 8 with the first hole 9 facing each other to serve as the crossbar 1 at the bottom of the beam. Insert bolts into the first hole 9 on the crossbar 1 and use nuts to clamp and fix the two ends of the crossbar 1 to the steel pipe uprights 5 on both sides of the beam.

[0044] Step 3: Select the appropriate hole position for the first hole on the crossbar 1 according to the dimensions of the beam's main cross section, and place the main rib 2 on the side of the beam. The channel steel end plate 12 of the main rib 2 is fastened to the crossbar 1 at the bottom of the beam, and the main rib 2 on the side of the beam is locked and fixed to the crossbar 1 at the bottom of the beam using bolts and nuts 4.

[0045] Step 4: The main rib diagonal brace 3 and the main rib on the beam side are assembled into a single unit using their respective lugs and pins. The length of the main rib diagonal brace is adjusted by rotating the internal threaded sleeve 16 on the main rib diagonal brace. The height of the main rib 2 on the beam side is adjusted by removing or lowering the first steel pipe 10 according to the height of the beam section. The main rib diagonal brace 3 is rotated, and the appropriate hole position of the first hole 9 on the crossbar 1 is selected. The crossbar 1 and the main rib diagonal brace 3 are then locked and fixed using bolts and nuts 4. At this point, the standardized formwork tool assembly is complete. After erecting the formwork and tying the reinforcing bars, concrete can be poured.

[0046] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Therefore, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model also intends to include these modifications and variations.
