Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a multifunctional retractable template structure. Background Art

[0002] During the construction or raising of flood control walls in water conservancy projects, the retaining wall is poured over a long distance and the wall top elevation requirements are strictly uniform. In actual operations, the foundation elevation of the newly poured retaining wall changes continuously with the shoreline. When raising the old retaining wall, the top of the old retaining wall will also be affected by uneven settlement, resulting in large differences in elevation. When a new retaining wall is poured on this basis, the strictly uniform wall top elevation and the constantly changing bottom elevation will lead to differences in the vertical height of the newly poured concrete, and the size of the side formwork will also be different.

[0003] In the construction of water conservancy projects, the templates usually have only a few relatively fixed sizes, and the vertical size of the templates cannot be adjusted flexibly and efficiently. In order to solve the need for multi-size templates when pouring hydraulic retaining walls, the traditional method is to cut and simply assemble the existing wooden templates on site to achieve the purpose of increasing or decreasing the size. This method is not only time-consuming and labor-intensive, but also the on-site cutting and assembly are not ideal for the size control. The temporary assembly density and rigidity of the templates are poor, and leakage often occurs when pouring concrete, affecting the construction quality and efficiency. Purchasing large quantities of templates of different sizes or customizing special templates before construction can also deal with this problem, but the cost is high and the secondary utilization rate of the templates is low. Utility Model Content

[0004] The problem to be solved by the utility model is to provide a multifunctional retractable formwork structure. By relative sliding of the first formwork and the second formwork along the main track, a certain gap can be generated between the first formwork and the second formwork. After the formwork extension piece is embedded in the gap, it can quickly adapt to the needs of pouring concrete retaining walls of different heights. It is not only convenient and fast, but also cost-saving.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a multifunctional retractable template structure, including a main track, a template extension, and a first template and a second template that can be relatively opened and closed along the length direction of the main track, and the first template and the second template are both slidably installed on the main track; the template extension can be embedded in the gap between the first template and the second template, and the side of the template extension is flush with the side of the first template and the second template.

[0006] Optionally, a groove is provided in the middle of the main track, and two ends of the main track are bent to form sliding grooves, and the sliding grooves are connected to the grooves.

[0007] Optionally, the first template and the second template are respectively slidably connected to the main track through a first track and a second track, and one side of the first track and the second track is fixedly connected to the first template and the second template respectively, and the other side is slidably embedded in the groove and the chute.

[0008] Optionally, the first track includes a bottom plate, a convex block is arranged on one side of the bottom plate, and side plates are fixedly connected to both sides of the convex block; the bottom plate is fixedly connected to the first template, one end of the convex block can be embedded in the groove, and the side plate can be embedded in the chute.

[0009] Optionally, the bottom plate, the convex block and the side plate adopt an integrally formed structure, and the cross section of the first track is in a T-shaped structure.

[0010] Optionally, first groove teeth and second groove teeth are respectively arranged at opposite ends of the first template and the second template, and the first groove teeth and the second groove teeth are engaged with each other.

[0011] Optionally, a first connecting tooth capable of being engaged with the first groove teeth is arranged at one end of the template extension, and a second connecting tooth capable of being engaged with the second groove teeth is arranged at the other end.

[0012] Optionally, a first scale for measuring the gap distance between the first template and the second template is arranged on one side of the main track opposite to the template extension, and a second scale for measuring the lifting height of the first template is arranged on one side of the first track opposite to the template extension.

[0013] Optionally, there are two main tracks, and the two main tracks are symmetrically arranged on the same side of the first template and the second template.

[0014] Beneficial effects

[0015] (1) In the utility model, the first template and the second template can slide relative to each other along the main track. When a gap is generated between the two, a template extension with a suitable height can be embedded in the gap to quickly meet the requirements of pouring concrete retaining walls with different heights. It is not only convenient and fast, can save costs, but also can enhance the overall rigidity of the template structure through the main track.

[0016] (2) In the utility model, through the mutual engagement between the first groove teeth and the second groove teeth, it can be ensured that there is good sealing between the first template and the second template without adding a template extension. Similarly, through the engagement relationship between the first connecting tooth and the second connecting tooth and the first groove teeth and the second groove teeth respectively, it can be ensured that the template structure still has good sealing when the template extension is added, which can prevent slurry leakage and improve the construction quality.

[0017] (3) In the present invention, by setting the first scale and the second scale, the control over the pouring elevation can be enhanced, thereby improving the efficiency of template structure construction and retaining wall pouring. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] Embodiment 1

[0026] like Figure 1-Figure 2 As shown, a multifunctional retractable template structure includes a main track 1, a template extension 4, and a first template 2 and a second template 3 that can be relatively opened and closed along the length direction of the main track 1, and the first template 2 and the second template 3 are both slidably installed on the main track 1; the template extension 4 can be embedded in the gap between the first template 2 and the second template 3, and the side of the template extension 4 is flush with the side of the first template 2 and the second template 3.

[0027] Before use, according to the requirements of the pouring height of the retaining wall, select formwork extension parts 4 of different heights; during use, the first formwork 2 is located above the second formwork 3. Place this formwork structure at the designated position and manually lift the first formwork 2. During the lifting process, the first formwork 2 moves upward along the length direction of the main track 1 until it reaches the designated height. At this time, a certain height gap is generated between the first formwork 2 and the second formwork 3. Then, embed the formwork extension part 4 into the gap between the first formwork 2 and the second formwork 3 to ensure that the side surface of the formwork extension part 4 is flush with the side surfaces of the first formwork 2 and the second formwork 3. Subsequently, the height extension of the formwork is completed; after use, lift the first formwork 2 upward by a certain distance, remove the formwork extension part 4, and then release the first formwork 2 to make it fall back into place and close with the second formwork 3. Then, place this formwork structure at the designated position for storage.

[0028] As described above, the first formwork 2 and the second formwork 3 can slide relative to each other along the main track 1. When a gap is generated between them, a formwork extension part 4 of a suitable height can be embedded into this gap to quickly meet the requirements of pouring concrete retaining walls of different heights. It is not only convenient and fast, can save costs, but also can enhance the overall rigidity of this formwork structure through the main track 1.

[0029] Among them, one end of the main track 1 always abuts against the ground, and the second formwork 3 located below can also slide along the main track 1 to ensure that this structure can achieve the layer-by-layer pouring of retaining walls of different heights.

[0030] Furthermore, in order to improve the overall rigidity of this structure, the number of main tracks 1 can also be increased as needed. For example, there are two main tracks 1, and the two main tracks 1 are symmetrically arranged on the same side of the first formwork 2 and the second formwork 3; at this time, the sides of the first formwork 2, the second formwork 3, and the formwork extension part 4 opposite to the main track 1 are the working surfaces. Therefore, it is necessary to ensure that the same side surfaces of the three are flush with each other.

[0031] Such as Figure 3-Figure 5 As shown, the middle part of the main track 1 has a groove 11, and both ends of the main track 1 are bent to form chutes 12, and the chutes 12 are communicated with the groove 11; the first formwork 2 and the second formwork 3 are respectively slidably connected to the main track 1 through the first track 5 and the second track 6. One side of the first track 5 and the second track 6 is respectively fixedly connected to the first formwork 2 and the second formwork 3, and the other side is slidably embedded in the groove 11 and the chute 12.

[0032] Specifically, the first track 5 includes a bottom plate 51. One side of the bottom plate 51 is provided with a convex block 52, and both sides of the convex block 52 are fixedly connected with side plates 53; the bottom plate 51, the convex block 52, and the side plates 53 are of an integrally formed structure, and the cross-section of the first track 5 is in a T-shaped structure.

[0033] As mentioned above, the first track 5 is manufactured by integral molding, which can enhance the overall strength of the first track 5, and the bottom plate 51 is fixedly connected to the first template 2, one end of the protrusion 52 can be embedded in the groove 11, and the side plate 53 can be embedded in the slide groove 12. The sliding of the end of the protrusion 52 in the groove 11 can improve the guidance of the movement of the first track 5 relative to the main track 1; the ends of the two side plates 53 are respectively slidably embedded in the slide grooves 12 at both ends of the main track 1, which can improve the strength of the sliding connection between the first track 5 and the main track 1, so as to more effectively resist the radial tension generated during the pouring process and avoid the distortion between the first template 2, the second template 3 and the template extension 4.

[0034] The structure of the second track 6 is similar to that of the first track 5 , and only the length is different, so it will not be described here.

[0035] like Figure 1 As shown, the main track 1 is provided with a first scale 7 for measuring the gap distance between the first template 2 and the second template 3 on the side opposite to the template extension 4, and the first track 5 is provided with a second scale 8 for measuring the lifting height of the first template 2 on the side opposite to the template extension 4.

[0036] The first scale 7 and the second scale 8 are similar to existing rulers, and the distance is measured by the position on the scale line; the first scale 7 can be used to measure the gap distance between the first template 2 and the second template 3, so as to quickly and accurately select the template extension 4 of the appropriate height; the position of the upper end of the main track 1 on the scale line of the second scale 8 can be used to measure the height of the first template 2, and vice versa, it can be determined whether the first template 2 is lifted in place. By setting the first scale 7 and the second scale 8, the control of the casting elevation can be enhanced, and the efficiency of template structure construction and retaining wall casting can be improved.

[0037] Working principle:

[0038] When in use, the template structure is placed at a designated position, and the first template 2 is manually raised; during the raising process, the first track 5 fixedly connected to the first template 2 moves up along the length direction of the main track 1, and the second scale 8 on the first track 5 determines whether the first template 2 reaches the designated height; at this time, a gap of a certain height is generated between the first template 2 and the second template 3, and the height distance of the gap is measured by the first scale 7 on the main track 1. Template extension pieces 4 of different sizes are reasonably selected according to the gap height, and the selected template extension piece 4 is embedded between the first template 2 and the second template 3, and the template extension is completed;

[0039] After use, the first template 2 is lifted up a certain distance, the template extension 4 is removed, and then the first template 2 is released to fall back to its original position and close with the second template 3, and then the template structure is placed in a designated position for storage.

[0040] Among them, when the first template 2 falls back to its position and closes with the second template 3, the first track 5 is completely embedded in the interior of the main track 1. As the first template 2 moves upward relative to the second template 3, the end of the first track 5 protrudes out of the main track 1. At this time, the distance that the first template 2 is lifted can be determined according to the first scale 7 on the first track 5.

[0041] Embodiment 2

[0042] like Figure 2 As shown, on the basis of the first embodiment, the first and second groove teeth 21 and 31 are respectively provided at opposite ends of the first and second templates 2 and 3, and the first groove teeth 21 and the second groove teeth 31 are interlocked.

[0043] After the first formwork 2 and the second formwork 3 are closed, if the height of the formwork structure meets the casting requirements, there is no need to expand the height of the formwork structure. At this time, the opposite ends of the first formwork 2 and the second formwork 3 are engaged with each other through the first groove teeth 21 and the second groove teeth 31 to ensure good sealing between the first formwork 2 and the second formwork 3 to prevent leakage.

[0044] Among them, the first groove tooth 21 is located at the bottom of the first template 2, and has a notch on one side; the second groove tooth 31 is located at the top of the second template 3, and also has a notch on one side; when the first template 2 and the second template 3 are closed, the first groove tooth 21 can be completely embedded in the notch on one side of the second groove tooth 31, and the second groove tooth 31 can also be completely embedded in the notch on one side of the first groove tooth 21, thereby achieving complete interlocking and preventing slurry from leaking from the gap between the first template 2 and the second template 3.

[0045] Similarly, in order to avoid leakage of slurry in the gap between the template extension 4 and the first template 2 and the second template 3, a first connecting tooth 41 that can be engaged with the first groove tooth 21 is provided at one end of the template extension 4, and a second connecting tooth 42 that can be engaged with the second groove tooth 31 is provided at the other end. This structure can also ensure that the working surfaces of the first template 2, the second template 3 and the template extension 4 are flush with each other.

[0046] In summary, the multifunctional retractable formwork proposed in the utility model can greatly improve the formwork efficiency for casting retaining walls of different heights, enhance the rigidity of the formwork structure, and improve the elevation control level and the quality of retaining wall casting.

[0047] A slidable first track 5 and a second track 6 are embedded inside the main track 1. The first track 5 is fixedly connected to the first template 2, and the second track 6 is fixedly connected to the second template 3, and the template structure is also equipped with template extensions 4 of different sizes; according to actual use requirements, the first template 2 and the first track 5 are lifted to a specified height along the main track 1, and the template extension 4 is embedded in the gap between the first template 2 and the second template 3 to complete the height expansion of the template structure; groove teeth are provided at the ends of the first template 2 and the second template 3, and correspondingly, connecting teeth are also provided at both ends of the template extension 4 to facilitate the fitting between the components to prevent leakage; the main track 1, the first track 5, and the second track 6 jointly enhance the rigidity of the template structure, and a first scale 7 is provided on the main track 1, and a second scale 8 is provided on the first track 5. The overall height of the template structure after expansion and contraction can be quickly calculated through the second scale 8, and the height of the template extension 4 can be quickly identified through the first scale 7.
