Description

Technical Field

[0001] This utility model relates to the field of template technology, and in particular to a template with an adjustable positioning ring. Background Technology

[0002] Variable diameter structures typically have curved surfaces. Casting such structures requires either variable diameter formwork or formwork of the same height as the building. Formwork of the same height is generally suitable for relatively low-rise buildings, but for taller buildings, it is difficult to manufacture and inconvenient to construct. Variable diameter formwork involves pouring in stages. After each pour, a climbing device is used to raise the formwork before the next pour, and this cycle continues until the entire structure is complete. Since the diameter of each pour is different, it is necessary to adjust the formwork after each pour to accommodate the diameter requirements of the next pour. Variable diameter formwork is usually formed by multiple formwork units connected by an adjusting mechanism. During each adjustment, the corresponding formwork unit is removed, and the remaining units are reassembled using the adjusting mechanism. During reassembly, because the lower end of the formwork is confined by the concrete, the lower end only needs to be adjusted to contact the concrete. The upper end of the formwork has not yet been poured with concrete, and adjacent formwork units must be adjusted using the adjusting mechanism to meet design requirements, preventing the upper opening of the formwork from being too small or too large.

[0003] like Figure 1 As shown, each template unit currently has multiple adjustment mechanisms in the vertical direction, and adjacent template units also have multiple adjustment mechanisms in the vertical direction. Therefore, the template as a whole has a large number of adjustment points. The adjustment mechanism mainly uses the adjustment screw and nut to achieve the adjustment structure, and each adjustment requires rotating the adjustment screw. Each adjustment point requires a certain amount of time. In addition, the large number of adjustment points results in a long adjustment time when the current template is adjusted for diameter reduction. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adjustable positioning ring template that can quickly position the upper end of the template body.

[0005] To solve the above problems, this utility model provides an adjustable positioning ring template, which includes a template body with adjustable diameter and a positioning ring that can be detachably installed on the template body or placed on the upper end of the template body. The positioning ring is used to position the upper end of the template body.

[0006] Furthermore, the template body is provided with a positioning stop bar that is adapted to the positioning ring, and the positioning stop bar is located on the outside of the positioning ring when it is engaged with the positioning ring.

[0007] Furthermore, the positioning bar has a guide slope for guiding the positioning ring.

[0008] Furthermore, the positioning ring includes at least two positioning elements, at least one of which is connected to the template body.

[0009] Furthermore, each end of the positioning member is provided with a connecting seat, and the connecting seat is connected to the template body or the connecting seat of the adjacent positioning member through a locking assembly.

[0010] Furthermore, the template body is provided with a fixing seat that connects to the connecting seat.

[0011] Furthermore, a reinforcing member is provided between the connecting seat and the positioning member to strengthen the connection.

[0012] Furthermore, the positioning element is a channel steel, or the positioning element includes two channel steels and a connecting plate for connecting the channel steels.

[0013] Furthermore, it also includes a clamping mechanism for tightening the template body.

[0014] Furthermore, the clamping mechanism includes a clamping member for clamping the template body and an adjuster for adjusting the clamping force. One end of the clamping member is fixed to the template body, the adjuster is installed on the template body, and the other end of the clamping member passes around the template body and is connected to the adjuster.

[0015] Furthermore, one end of the clamping member is also fixed to the template body via an adjuster.

[0016] Furthermore, the adjuster includes an adjusting seat fixed to the template body, an adjusting screw connected to the clamping member, and an adjusting nut for cooperating with the adjusting seat to limit the position of the adjusting screw. The adjusting screw passes through the adjusting seat and is mounted on the adjusting nut.

[0017] Furthermore, the template body is provided with vertical trusses to increase strength.

[0018] Furthermore, the truss includes multiple support columns connected to the template body and connecting columns that connect and fix the multiple support columns.

[0019] This utility model features an adjustable positioning ring template that quickly positions the upper end of the template body using a positioning ring. After diameter reduction, the positioning ring of the corresponding size can be replaced, which can meet the needs of diameter reduction. Unlike existing technologies, there is no need to adjust the adjustment mechanism one by one, making positioning convenient and fast. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] Example 1

[0035] First, it should be understood that, generally speaking, the template body 1 is formed by combining multiple template units, and the inner contour formed by the template units is consistent with the contour of the building. Each template unit includes at least a panel 11 and vertical back ribs 12 provided on the side wall of each panel 11. The shape of the panel 11 is consistent with the contour of the building. In this embodiment, the building is elliptical, that is, the template units are divided into straight template units and curved template units, and the corresponding panels 11 are straight panels 11 and curved panels 11. For template units that do not require diameter change, a transverse back rib 13 can also be provided on the panel 11, that is, the straight template unit in this embodiment. The diameter change in this embodiment is consistent with the prior art, which usually means replacing or removing the curved template unit.

[0036] like Figures 2 to 4 As shown, a preferred embodiment of the adjustable template with positioning ring 2 of this utility model includes a template body 1, a positioning ring 2, and a clamping mechanism 3. The template body 1 is a variable-diameter template body 1; the positioning ring 2 is detachably installed on the template body 1 to facilitate replacement of the positioning ring 2, allowing for openings at the top of the template body 1 at different positions, thus enabling rapid positioning even after tapering or changing diameter. The clamping mechanism 3 is used to clamp the template body 1, ensuring that the template body 1 does not come apart; multiple clamping mechanisms 3 are arranged in the height direction. In other embodiments, the positioning ring 2 can also be placed on the template body 1 by placement. This placement method is typically used when the building is relatively small, and therefore the positioning ring 2 is also relatively small.

[0037] like Figure 5 and Figure 6As shown, the template body 1 is also provided with a truss 14, which is welded to the vertical back rib 12 to increase the strength of the vertical back rib 12 and ensure that the panel 11 will not be bent by the clamping mechanism 3, especially at the position where it does not come into contact with concrete. The truss 14 is arranged vertically to ensure that the truss 14 will not affect the change in diameter of the panel 11. In order to save costs, the truss 14 is usually set on the vertical back rib 12 of the larger panel 11, and the truss 14 is set at intervals, not on every vertical back rib 12. The truss 14 includes support columns 141 and connecting columns 142. Multiple support columns 141 are provided on the connecting columns 142. The support columns 141 are welded and fixed to the vertical back rib 12, so that the truss 14 and the vertical back rib 12 form multiple support points to ensure that the vertical back rib 12 will not bend, so as to achieve the purpose of preventing the panel 11 from bending. The template body 1 is provided with a positioning stop 4, which is fixed to the top of the vertical back rib 12. The positioning stop 4 is located at the upper opening of the template body 1 and is used to fit with the positioning ring 2. When the positioning stop 4 is engaged with the positioning ring 2, it is located on the outside of the positioning ring 2, that is, the outer wall of the positioning ring 2 abuts against the positioning stop 4. The positioning stop 4 can be set at intervals or on each vertical back rib 12. Of course, positioning stop 4 will not be set at positions that interfere with other components. The upper end of the positioning stop 4 is provided with a guide slope, which is used to guide the positioning ring 2 to ensure that the positioning ring 2 can fall into the positioning stop 4 more easily when it is installed or placed.

[0038] Combination Figure 6 , Figure 7 and Figure 8Referring to the diagram, the positioning ring 2 includes six positioning elements 21, two of which are straight and the remaining four are curved. The specific distribution of the straight and curved positioning elements 21 is consistent with the designed building; that is, the two straight positioning elements 21 are arranged opposite each other, and the same end of the two straight positioning elements 21 is detachably connected by the two curved positioning elements 21. The straight positioning elements 21 are installed on the straight template unit, and the curved positioning elements 21 are detachably connected to each other and to the straight positioning elements 21. In other embodiments, the straight positioning elements 21 can also be used as the back ribs of the template body 1, that is, the uppermost transverse back rib 13 of the straight template unit can be used as the straight positioning elements 21. It should be understood that there can be four positioning components 21. The number of positioning components 21 mainly depends on the size of the building, and the shape of the positioning components 21 depends on the shape of the building. When the building is relatively small, only one positioning component 21 that matches the outline and size of the building can be used as the positioning ring 2. When the building is relatively large, the positioning ring 2 needs to be segmented, that is, multiple positioning components 21 are combined to form the positioning ring 2. Setting the positioning ring 2 as a single positioning component 21 assembled together breaks down the positioning ring 2 into smaller parts, which facilitates transportation.

[0039] Each end of the positioning element 21 is provided with a connecting seat 22, and the connecting seats 22 between adjacent positioning elements 21 are connected by a locking assembly; the locking assembly is a bolt assembly. A reinforcing element 23 is also provided between the connecting seat 22 and the positioning element 21, and the reinforcing element 23 is used to strengthen the connection between the connecting seat 22 and the positioning element 21. In order to increase the connection between the positioning ring 2 and the template body 1, a fixing seat 15 is added at the connection of the two arc-shaped positioning elements 21. The fixing seat 15 is welded and fixed to the template body 1, usually welded to the truss 14. In this embodiment, the arc-shaped positioning element 21 includes two channel steels 211 and a connecting plate 212 connecting the two channel steels 211. The connecting plate 212 is welded to the two channel steels 211, and the top and bottom surfaces of the two channel steels 211 are both welded with the connecting plate 212, which are distributed at intervals on the channel steels 211. The positioning component 21 is made of two channel steels 211 and a connecting plate 212, which ensures the strength of the positioning component 21 while reducing its weight, facilitating assembly and transportation. In this embodiment, the straight positioning component 21 uses a single channel steel 211. In other embodiments, the structure of the positioning component 21 can be selected according to requirements; that is, it can be a structure with only two channel steels 211 and a connecting plate 212, or it can be a structure with only one channel steel 211.

[0040] like Figure 9As shown, each of the clamping mechanisms 3 includes a clamping member 31 and an adjuster 32. One end of the clamping member 31 is fixed to a certain position of the template body 1, and the other end of the clamping member is wound around the template body 1 and connected to the adjuster 32. The adjuster 32 is fixed to another position of the template body 1. The clamping member 31 is used to clamp the template body 1, and the adjuster 32 adjusts the clamping force. In other embodiments, one end of the clamping member 31 can also be fixed to the template body 1 via the adjuster 32.

[0041] Specifically, one end of the clamping member 31 is welded and fixed or installed on a straight segment of the template unit via other components. The adjuster 32 is installed on another straight segment of the template unit. The clamping member 31 is wound around the arc-shaped template unit to tighten it. It should be noted that when the building is relatively small, the fastener and the adjuster 32 can be installed on the same template unit. The clamping member 31 is wound around the template body 1 from the direction of the adjuster 32 and then connected to the adjuster 32. The clamping member 31 is made of steel strip. In other embodiments, the clamping member 31 can also be made of a retractable material such as steel wire rope. When a retractable material is used, the adjuster 32 adopts a winding mechanism. The adjuster 32 includes an adjusting seat 321, an adjusting screw 322, and an adjusting nut 323. The adjusting seat 321 is fixed to the template unit on the straight section of the template body 1. One end of the adjusting screw 322 is fixed to the clamping member 31. The adjusting seat 321 has a through hole, and the other end of the adjusting screw 322 passes through the through hole in the adjusting seat 321 and extends out of the adjusting seat 321. The adjusting nut 323 is screwed onto the adjusting screw 322. When tightening is required, rotating the adjusting nut 323 moves the adjusting screw 322 towards the adjusting nut 323, thereby completing the tightening. During the tightening process, the positioning stop 4 on the template body 1 gradually approaches the positioning ring 2. Tightening stops when the positioning stop 4 contacts the positioning ring 2. The diameter of the adjusting nut 323 is larger than the diameter of the through hole, ensuring that the adjusting nut 323 cannot pass through the adjusting seat 321, thus ensuring that it can fix the position of the adjusting screw 322 and thereby fix the position of the clamping member 31.

[0042] During the initial installation of the template body 1, first install the template unit connected to the positioning ring 2, then install the positioning ring 2 onto the corresponding template unit, then install the remaining template units, and finally install the clamping mechanism 3 to tighten all the template units. During diameter reduction / reduction, first replace the arc-shaped positioning piece 21 to complete the diameter reduction of the positioning ring 2, then perform the diameter reduction / reduction and operate the clamping mechanism 3 again. Both initial installation and diameter reduction / reduction utilize the positioning ring 2 to quickly position the upper end of the template body 1, eliminating the need for individual adjustment mechanisms as in existing technologies. Simply place the positioning stop 4 against the positioning ring 2; positioning is convenient and quick.

[0043] Example 2

[0044] like Figure 10 and Figure 11 As shown, this embodiment takes a circular building as an example, meaning the template unit only has arc-shaped template units. In other words, the adjustable template with positioning ring 2 of this utility model is also applicable to circular buildings. Correspondingly, all the positioning elements 21 are arc-shaped positioning elements 21, and the adjuster 32 is installed on the arc-shaped template unit.

[0045] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, whether directly or indirectly applied to other related technical fields, shall also be within the patent protection scope of this utility model.
