Description

Technical Field

[0001] The utility model belongs to the technical field of construction auxiliary devices, and particularly relates to a movable formwork device for a thin-walled concrete pool body. Background Technique

[0002] Generally, for a common existing pool structure, its wall thickness is about 200 mm. And the above-mentioned thin-walled concrete pool body refers to that the wall thickness of the pool body is 40 - 50 mm, and the latter has the prominent advantage of low construction cost. Moreover, when the thin-walled concrete pool body is of the precast type, it also has the advantage of convenient transportation.

[0003] Correspondingly, due to the relatively small wall thickness of the pool body, for the pool wall formwork, it is necessary to provide more stable and comprehensive support strength. On the other hand, the above-mentioned "movable" means that after the concrete area corresponding to the formwork device is completely cured, the formwork body slides horizontally to support the next area of the formed pool wall, and finally realizes the energy-saving effect of sequential use of the formwork.

[0004] For example, the Chinese utility model patent with the authorization announcement number CN214836414U and the authorization announcement date of November 23, 2021 discloses a movable formwork for a thin-walled concrete retaining wall, including a track, on the surface of which a movable formwork is slidably connected. The movable formwork includes a bottom plate slidably connected to the track, a groove is opened at the top of the bottom plate, and a rocker is provided on one side of the bottom plate, and a rotating rod is fixedly installed on the surface of the rocker.

[0005] The general structural principle and advantages of the movable formwork in this utility model patent are as follows: moving the movable formwork on the surface of the track reduces the installation and disassembly of the construction formwork. At the same time, the setting of the track can improve the linear control effect of the movable slide rail, preventing deviation during movement and affecting the pouring thickness. Through the setting of the movable formwork, the distance from the wall surface can be adjusted.

[0006] However, during the actual use of the movable formwork in the construction of a pool, there are at least the following two deficiencies, which are also the technical problems to be solved by this utility model, that is:

[0007] First, the extending and retracting structure of its formwork body is too complex, including multiple screwing positions and meshing positions, so the use cost is greatly increased;

[0008] Second, for a pool, the pouring sequence is generally bottom first and then wall. Therefore, its installation nail structure will damage the pool bottom structure when fixed, which is not practical. The subsequent hole structure left needs to be filled again, ultimately reducing the overall construction efficiency.

[0009] Therefore, in summary, there is an urgent need for a new type of movable formwork device that does not damage the bottom structure of the pool during installation and has relatively simple and convenient operations for extending and retracting the formwork body, so as to be used for casting the pool wall of a thin-walled concrete pool body.

Specific implementation mode

[0034] The following is only the preferred embodiment of the present invention, and does not limit the scope of the present invention.

[0035] As shown in the attached Figure 1-8 As shown, a movable formwork device for a thin-walled concrete pool body, the structure includes a vertical formwork 11, and also includes a counterweight bottom plate unit 1, a track plate unit 2 arranged on the counterweight bottom plate unit 1, a sliding frame unit 3 sleeved on the track plate unit 2, and a telescopic rod unit 4 arranged on the sliding frame unit 3 and connecting the vertical formwork 11.

[0036] In this embodiment, the vertical formwork 11 is a common existing wooden formwork or plastic formwork, and it is only necessary to ensure sufficient self-bending performance and sufficient demoulding ability. Its shape is rectangular, and the length of its horizontal side is much smaller than the length of the counterweight bottom plate unit 1. For example, the size of the former can be 20-30% of the latter.

[0037] The main material of the counterweight bottom plate unit 1 is wood or steel, and its weight is relatively large. After being placed on the pool bottom slab b, it can stably support the vertical formwork 11, so that the pushing force of the concrete material required for the pool wall on the vertical formwork 11 is much smaller than the static friction force obtained by the counterweight bottom plate unit 1 on the pool bottom slab b. Correspondingly, at this time, it is relatively laborious to move and shift the counterweight bottom plate unit 1, but for the beneficial effect of protecting the pool bottom slab b, it is worthwhile.

[0038] The main materials of the track plate unit 2, the sliding frame unit 3 and the telescopic rod unit 4 are all plastic or steel. After the track plate unit 2 is combined with the sliding frame unit 3, its functions are: First, to provide the vertical height required for the installation of the vertical formwork 11; Second, to provide the limiting track required for the horizontal sliding of the vertical formwork 11.

[0039] The functions of the telescopic rod unit 4 are as follows: First, after the counterweight bottom plate unit 1 is placed in a suitable position, the protruding distance of the vertical formwork 11, that is, the distance from the side of the foundation a, is finely adjusted. The operation of selecting a suitable placement position for the former is rough adjustment. Second, after the above fine adjustment operation, it is fixed to prevent the vertical formwork 11 from retracting backward during the pouring of concrete, that is, to prevent the vertical formwork 11 from accidentally moving away from the side of the foundation a.

[0040] The counterweight bottom plate unit 1 is further provided with a support hole plate unit 5 for connecting the track plate unit 2, and the vertical formwork 11 is further provided with an auxiliary support rod unit 6 for inserting the support hole plate unit 5.

[0041] In this embodiment, the first function of the support hole plate unit 5 is to reinforce the track plate unit 2, so that the reaction force of the sliding frame unit 3 on the track plate unit 2 will not cause the latter to break.

[0042] The second function of the support hole plate unit 5 is to cooperate with the auxiliary support rod unit 6 to provide a lateral support effect on both the upper and lower parts of the vertical formwork 11, ensuring that the vertical formwork 11 is not easily bent and deformed, otherwise the cast pool wall will be deformed.

[0043] The counterweight bottom plate unit 1 includes a rectangular bottom plate 101 and a counterweight 102 provided on the rectangular bottom plate 101.

[0044] In this embodiment, the counterweight 102 is an iron block, and its number is 2, which are respectively located on both sides of the support hole plate unit 5. Its length is slightly less than that of the rectangular bottom plate 101, and its height is lower than that of the auxiliary support rod unit 6, finally providing sufficient and appropriate weight.

[0045] The counterweight bottom plate unit 1 further includes a positioning groove 103 provided on the upper surface of the rectangular bottom plate 101 for installing the counterweight 102, and an anti-slip rubber plate 104 provided on the lower surface of the rectangular bottom plate 101.

[0046] In this embodiment, the function of the positioning groove 103 is to prevent the counterweight 102 from slipping and separating from the rectangular bottom plate 101. The rubber material of the anti-slip rubber plate 104 has a larger friction coefficient compared to the wooden or iron rectangular bottom plate 101, and can provide a greater static friction force on the pool bottom plate b to prevent the device from being pushed and displaced by the concrete during pouring.

[0047] On the other hand, the lower surface of the anti-slip rubber plate 104 is flush with the lower end surface of the vertical formwork 11, or the latter is slightly higher, ensuring that when the device is used on the pool bottom plate b, the lower end surface of the vertical formwork 11 is fully and appropriately pressed on the pool bottom plate b. Otherwise, if a large gap is left at this place, concrete will leak out.

[0048] The track plate unit 2 includes two groups of inclined support plates 201 respectively arranged at both ends of the rectangular bottom plate 101, and a transverse plate 202 arranged on the two groups of inclined support plates 201 at both ends and used for installing the sliding frame unit 3.

[0049] In this embodiment, the number of the inclined support plates 201 is four in total, two in a group, respectively arranged at both ends of the transverse plate 202, and at the same time, they are also the limit points for the left-right sliding operation of the sliding frame unit 3.

[0050] Among them, the upper ends of the two inclined support plates 201 in the same group are relatively close to each other, and the lower ends are relatively far away from each other, and the contour shape is triangular.

[0051] The sliding frame unit 3 includes a rectangular frame 301 sleeved on the transverse plate 202, and a rubber damping sheet 302 arranged on the inner bottom surface of the rectangular frame 301 and used for clamping the lower surface of the transverse plate 202.

[0052] In this embodiment, the rubber damping sheet 302 is adhesively fixed. The vertical inner side surface and the inner top surface of the rectangular frame 301 fully fit the transverse plate 202, and the rubber damping sheet 302 fully clamps the lower surface of the transverse plate 202.

[0053] So far, in the length direction of the telescopic rod unit 4, the rectangular frame 301 and the transverse plate 202 are relatively tightly engaged, and there is appropriate friction between them in the vertical direction, so that the rectangular frame 301 is difficult to accidentally slide, and the resistance during the sliding operation is moderate.

[0054] The telescopic rod unit 4 includes a transverse fixed pipe 401 arranged on the outer side surface of the rectangular frame 301, a plug-and-play screw 402 with one end inserted into the transverse fixed pipe 401 and the other end connected to the vertical formwork 11, and an adjusting nut 403 arranged on the plug-and-play screw 402 and used for clamping the end surface of the transverse fixed pipe 401.

[0055] In this embodiment, the direct function of the adjusting nut 403 is to adjust the length of the inserted section of the plug-and-play screw 402 on the transverse fixed pipe 401, so that the distance between the vertical formwork 11 and the side surface of the foundation a is the distance required for pouring the thin-walled concrete pool body.

[0056] The above adjustment operation is only carried out before pouring. On the other hand, when the vertical formwork 11 moves horizontally to switch the support position, the vertical formwork 11 does not need to move away from the pool wall during pouring first and then slide, but directly slides horizontally. At this time, the horizontal fixed pipe 401 or the plug-in screw 402 can be the position held by hand for the above horizontal sliding operation.

[0057] As shown in the Figure 7 attachment, the number of the adjusting nuts 403 is two. After the nut on the left side in the figure is adjusted to the required position, the nut on the right side clamps it, so that the whole of the two is not likely to rotate and displace spontaneously on the plug-in screw 402. Otherwise, the vertical formwork 11 may retract backward, that is, away from the side of the foundation a, and finally cause the deformation of the thin-walled concrete pool body and an unexpected increase in thickness.

[0058] The horizontal fixed pipe 401 is a square pipe, the vertical cross-sectional shape of the plug-in screw 402 is square, and a chamfered thread section 402-1 for screwing the adjusting nut 403 is provided on the edge of the plug-in screw 402.

[0059] In this embodiment, the square-column-shaped plug-in screw 402 is fully engaged with the square-pipe-shaped horizontal fixed pipe 401 in the circumferential direction, avoiding unnecessary left-right swing of the plug-in screw 402 together with the vertical formwork 11 in the vertical direction.

[0060] Of course, after the auxiliary support rod unit 6 is set, the above effect of avoiding left-right swing in the vertical direction is better.

[0061] In addition, the 4 chamfers on the cross-section of the plug-in screw 402 are in a co-circular positional relationship. The forming method of the plug-in screw 402 can be equivalent to: cutting off 4 equal-length segments with a cross-section of a minor-arc segment on an ordinary stud, and the remaining original thread segment is the above chamfered thread section 402-1.

[0062] So far, the plug-in screw 402 has both the dual functions of: not being easily rotated by itself in the circumferential direction; and effectively screwing the adjusting nut 403 in the length direction.

[0063] The support hole plate unit 5 includes a rectangular cross plate 501 arranged on the upper surface of the counterweight bottom plate unit 1, two groups of vertical plates 502 respectively arranged at both ends of the rectangular cross plate 501 and used for connecting the track plate unit 2, and a horizontal rectangular hole 503 arranged on the rectangular cross plate 501 and used for inserting the auxiliary support rod unit 6.

[0064] In this embodiment, the projected positions of the two inclined support plates 201 and the centered vertical plate 502 on the vertical formwork 11 coincide, and the three together form the end positions for the left - right sliding operation of the rectangular frame 301, preventing the rectangular frame 301 from falling off the transverse plate 202.

[0065] In addition, the rectangular transverse plate 501 is integrally formed with the rectangular bottom plate 101 and is located between the two counterweight blocks 102. The horizontal dimension of the horizontal rectangular hole 503 is sufficient and cannot further limit the horizontal sliding range of the auxiliary support rod unit 6. However, its vertical dimension is relatively small, and it needs to fit relatively tightly with the auxiliary support rod unit 6, so that the auxiliary support rod unit 6 can only slide horizontally and cannot swing left - right within the horizontal rectangular hole 503.

[0066] The auxiliary support rod unit 6 includes a lower screw 601 with one end inserted into the horizontal rectangular hole 503 and the other end connected to the lower part of the vertical formwork 11, and an auxiliary nut 602 arranged on the lower screw 601, engaging the side of the rectangular transverse plate 501 and used to support the vertical formwork 11.

[0067] In this embodiment, the quantity and usage of the auxiliary nut 602 are the same as those of the adjusting nut 403. In other words, when the device is idle and waiting to be used, the vertical formwork 11, together with the telescopic rod unit 4 and the auxiliary support rod unit 6, may slide out and fall together, but this does not affect its supporting use effect.

[0068] Among them, the lower screw 601 can be a common existing circular screw, or a square rod with a chamfered thread section like the plug - and - unplug screw 402. The advantage of the former is convenient production and use, and the disadvantage is that the horizontal rectangular hole 503 is likely to slowly wear the thread on the lower screw 601.

[0069] When the lower screw 601 is the above - mentioned circular screw, its diameter is slightly smaller than the vertical width dimension of the horizontal rectangular hole 503 to prevent the former from shifting up and down significantly within the latter.

[0070] After the auxiliary nut 602 and the adjusting nut 403 are all adjusted to the required positions and tightened inside themselves, the device can be used for support. During the process of the vertical formwork 11 sliding to switch the support position, no operation is required at the auxiliary nut 602.

[0071] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the gist of the present utility model. These are all non-creative modifications and are protected by the Patent Law as long as they are within the scope of the claims of the present utility model.
