Description
Technical Field
[0001] This application belongs to the technical field of concrete construction, and specifically relates to a simple fixing device for steel formwork of short walls. Background Art
[0002] In concrete construction projects, the installation and fixation of formwork are essential tasks. Whether the formwork is firmly fixed will have a great impact on the shape, size, and relative position of the concrete. To ensure that the steel formwork does not move or deform during concrete pouring, the formwork is often fixed by using steel pipe supports or tie rods.
[0003] In actual construction processes, there are usually some short walls, especially some walls with a height of less than 50 cm. Due to the limited height of the walls, using conventional steel pipe supports to fix the formwork or tie rods to fix the formwork requires a large amount of time and labor costs to build the base frame to fix the formwork, and the corresponding support pipes and formwork need to be removed after the concrete pouring is completed, which is time-consuming and laborious; and not fixing the formwork of short walls will also affect the shape and size of the concrete. Therefore, a simple fixing device for steel formwork for concrete construction of short walls is needed. Summary of the Invention
[0004] This application aims to provide a simple fixing device for steel formwork used in concrete pouring construction of short walls with a height less than 50 cm.
[0005] In one embodiment, a simple fixing device for steel formwork of short walls includes a formwork, a support column, a tie bar, and an adjusting member;
[0006] The formwork is symmetrically arranged on both sides of the wall to be poured. The top and bottom of the formwork are respectively constructed with upper flanges and lower flanges extending outward. The lower flange of the formwork is fixedly connected to the ground; At least a pair of support columns are symmetrically arranged on the upper flanges of the formwork on both sides. The support columns are fixedly connected to the upper flanges of the formwork and extend upward from the upper flanges of the formwork;
[0007] A first through hole is opened on the adjacent side end surface of the same pair of support columns, and the projections of the two first through holes of a group of symmetric support columns on any one of the support columns substantially coincide; The tie bar is inserted into the two first through holes of a group of symmetric support columns; Each tie bar corresponds to two adjusting members. The adjusting members are inserted into both ends of the tie bar, and the adjusting members are threadedly connected to the tie bar;
[0008] Wherein, after the adjusting member is screwed and moved to the first through hole on the tie bar, the adjusting member abuts against the end surface of the support column.
[0009] In an optional solution, the simple fixing device for steel formwork of short walls further includes a retaining piece, and a second through hole is opened on the retaining piece;
[0010] The support column is a channel steel, and the web of the channel steel is arranged adjacent to the inner side of the formwork. The first through hole is opened on the web of the channel steel; the retaining piece is arranged on the tie bar through the second through hole, and both end faces of the retaining piece are respectively abutted against the flange of the channel steel and the adjusting piece.
[0011] In an alternative solution, the formwork and the support column are detachably and fixedly connected.
[0012] In an alternative solution, a notch communicating with the first through hole is formed between the first through hole and the top edge of the support column, and the tie bar can be clamped into the first through hole through the notch.
[0013] In an alternative solution, the simple fixing device for the steel formwork of the low wall further includes a partition board;
[0014] The edge at the extended end of the formwork is constructed with a lateral folding edge towards the outside, and the partition board is detachably and fixedly connected to the lateral folding edges on both sides of the formwork.

[0016] In an alternative solution, a clamping groove is opened on one side of the support column adjacent to the concrete pouring area, and the clamping groove is clamped on the upper folding edge of the formwork;
[0017] Wherein, the clamping groove is opened adjacent to the bottom edge of the support column, the opening size of the clamping groove is consistent with the thickness of the upper folding edge of the formwork, and the depth of the clamping groove is at least greater than half of the thickness of the side end face of the support column.
[0018] Advantages of the present application:
[0019] During the pouring process of the low wall, the lateral stress of the concrete on the formwork is mainly concentrated in the upper half of the formwork. In the present application, a pair of support columns are arranged at the top of the formwork, and tie bars are used to tighten the support columns to offset the lateral stress exerted on the formwork after the concrete is poured; after the concrete solidifies and takes shape, the tie bars and the formwork can be quickly removed, effectively solving the problem of time-consuming and laborious in the traditional formwork fixing method.

[0033] To solve the problems in the background art, this application provides a simple fixing device for a steel formwork of a short wall, and the specific embodiments are as follows:
[0034] In one embodiment, please refer to Figure 1 and Figure 2 , this application provides a simple fixing device for a steel formwork of a short wall, including a formwork 1, a support column 2, a tie bar 3, and an adjusting member 4.
[0035] In this embodiment, the formwork 1 is symmetrically arranged on both sides of the wall to be poured. The top and bottom of the formwork 1 are respectively provided with an upper flange 11 and a lower flange 12 extending outward. The lower flange 12 of the formwork 1 is fixedly connected to the ground; at least a pair of support columns 2 are symmetrically arranged on the upper flanges 11 of the formwork 1 on both sides. The support columns 2 are fixedly connected to the upper flanges 11 of the formwork 1 and extend upward from the upper flanges 11 of the formwork 1.
[0036] In this embodiment, on one side end face adjacent to the same pair of struts 2, a first through hole is formed. The projections of the two first through holes of a set of symmetric struts 2 on any one of the struts 2 substantially coincide; the tension tie bars 3 are inserted into the two first through holes of a set of symmetric struts 2; each tension tie bar 3 corresponds to two adjusting members 4. The adjusting members 4 are inserted at both ends of the tension tie bar 3, and the adjusting members 4 are in threaded connection with the tension tie bar 3.
[0037] Among them, the adjusting member 4 can be a standard nut or a self-made part with a tapped central through hole. The outer diameter of the adjusting member 4 should be greater than the diameter of the first through hole; after the adjusting member 4 is screwed and moved on the tension tie bar 3 to the position of the first through hole, the adjusting member 4 abuts against the end face of the strut 2. By respectively abutting the adjusting members 4 on both sides against the end faces of the struts 2 on both sides, the tension tie bar 3 can be used to tension the formworks 1 on both sides. Thus, the simple fixing device for the steel formwork 1 of the short wall provided by the present application has a simple structure, flexible operation, convenient construction, and is safe and reliable, and can effectively solve the problem that a large amount of time and labor costs are consumed by using the traditional formwork 1 fixing method during the concrete pouring process of the short wall.
[0038] In an embodiment, the simple fixing device for the steel formwork 1 of the short wall further includes a retaining piece 5, and a second through hole is formed on the retaining piece 5.
[0039] In this embodiment, the strut 2 is a channel steel, and the web of the channel steel is arranged adjacent to the inner side of the formwork 1. The first through hole is formed on the web of the channel steel; the retaining piece 5 is arranged on the tension tie bar 3 through the second through hole, and the two side end faces of the retaining piece 5 respectively abut against the flange of the channel steel and the adjusting member 4. Among them, the retaining piece 5 is at least a set of rigid structure pieces with a maximum spacing greater than the width of the channel steel. The second through hole is approximately formed at the center position of the retaining piece 5, and the diameter of the second through hole should be greater than the diameter of the tension tie bar 3 and less than the minimum outer diameter of the adjusting member 4. If an integral profile or metal material is selected as the strut 2, certain requirements are needed for the thickness of the strut 2, which will correspondingly increase the material cost. By using the combination of the channel steel and the retaining piece 5 to replace the integral strut 2 structure, the cost can be saved. At the same time, since the retaining piece 5 and the channel steel are easy to process and obtain, the replacement cost is low, and it is also convenient for the sustainable use of the device.
[0040] In an embodiment, the formwork 1 and the strut 2 can be detachably fixedly connected by means of fasteners, insertion structures, snap structures, etc., so as to realize the convenient installation and disassembly of the formwork 1 and the strut 2, and facilitate the storage and recycling of each component of the device.
[0041] In one embodiment, a notch communicating with the first through-hole is formed between the first through-hole and the top edge of the support column 2, and the tension tie bar 3 can be snapped into the first through-hole through the notch. By forming a notch communicating with the first through-hole on the support column 2, the retaining plate 5 and the adjusting member 4 can be pre-assembled on the tension tie bar 3, and then the tension tie bar 3 together with the retaining plate 5 and the adjusting member 4 are snapped into the support column 2 through the notch and placed into the first through-hole, saving the steps of sequentially assembling the retaining plate 5 and the adjusting member 4 after the conventional threading of the tension tie bar 3 into the first through-hole, and improving the construction efficiency.
[0042] In one embodiment, referring to Figures 3 to 5 , the simple fixing device for the steel formwork 1 of the low wall further includes a partition plate 6. The edge at the extended end of the formwork 1 is constructed with a lateral folding edge towards the outside, and the partition plate 6 is detachably and fixedly connected to the lateral folding edges on both sides of the formwork 1. While the partition plate 6 segments the formwork 1, it can also assist in the support and fixation of the formwork 1. Among them, a number of through-holes for the steel bars of the steel reinforcement cage 8 to pass through are also formed on the partition plate 6; the detachable fixing method between the partition plate 6 and the formwork 1 can specifically be a fastener connection.
[0043] In one embodiment, referring to Figures 3 to 5 , the simple fixing device for the steel formwork 1 of the low wall further includes at least one double-headed hook 7. One end of the double-headed hook 7 is hung on the tension tie bar 3, and the other end of the double-headed hook 7 is hung on the steel reinforcement cage 8. By using the double-headed hook 7 to connect the tension tie bar 3 and the steel reinforcement cage 8, it can prevent the steel reinforcement cage 8 from sinking to the bottom and affecting the concrete pouring operation.
[0044] In one embodiment, a clamping groove is formed on one side of the support column 2 adjacent to the concrete pouring area, and the clamping groove is clamped on the upper folding edge 11 of the formwork 1. Among them, the clamping groove is formed adjacent to the bottom edge of the support column 2, the opening size of the clamping groove is the same as the thickness of the upper folding edge 11 of the formwork 1, and the depth of the clamping groove is at least greater than half of the thickness of the side end face of the support column 2. By using the clamping groove to clamp the support column 2 on the formwork 1 and combining the tension tie bar 3 to tighten the opposite support columns 2, it can provide a centripetal tightening force for the upper part of the formwork 1 while endowing the support column 2 with the ability to move flexibly along the upper folding edge 11 of the formwork 1 during the assembly with the formwork 1. Furthermore, the layout position and quantity of the support columns 2 can be adjusted according to the actual operation requirements, making the device more flexible and practical.
[0045] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
[0046] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included within the protection scope of the present application.
