[0006] The purpose of this utility model is to provide an early-stripping formwork support device for floor slab structures, which solves the problem that the existing technology cannot freely switch between keel fixing, slab fixing, or simultaneous early-stripping and late-stripping support, thus requiring the use of different structures for support, which easily leads to too many types of equipment, errors, or confusion during installation, thereby affecting construction efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An early stripping formwork support device for floor slab structures includes an adjustable base, a starting rod disposed on the adjustable base, a sweeping rod connected to two adjacent starting rods, and a vertical rod disposed on the starting rod. A horizontal bar is installed on two adjacent vertical rods, and an adjustable support head is installed on the vertical rod to freely switch between fixing the keel, fixing the shaping plate, or simultaneously supporting early stripping and late stripping.

[0009] Furthermore, the adjustable support head includes a first support rod that slides longitudinally with the upright, a second support rod that slides longitudinally with the first support rod, and a nut that is threadedly engaged with the upright and the first support rod to provide positioning support for the first and second support rods respectively. The first and second support rods are respectively provided with a U-shaped bracket and a flat support.

[0010] Furthermore, when the first support rod is sleeved outside the second support rod, the U-shaped bracket consists of two L-shaped structures on opposite sides of the first support rod. The planar brace cooperates with the two L-shaped structures on the second support rod, and a keel can be installed between the L-shaped structures on the same side and the planar brace; or

[0011] When the second support rod is sleeved outside the first support rod, the U-shaped bracket is an integral U-shaped structure set on the first support rod. The planar support includes a surface support structure set on the second support rod on both sides of the side opening of the U-shaped bracket. A keel can be installed between the surface support structure on the same side and the U-shaped bracket.

[0012] Furthermore, the panel structure includes a bottom support disposed on the second support rod, a vertical support disposed on the bottom support, and a top support disposed on the vertical support;

[0013] A keel can be installed between the top support or vertical support on the same side and the U-shaped bracket.

[0014] Furthermore, when the first support rod is sleeved outside the second support rod, the planar support includes multiple sets of opposing support blocks disposed on one side of the top of the second support rod and whose top surface is located on the same horizontal plane as the top surface of the second support rod;

[0015] The U-shaped bracket at the position corresponding to the support block is provided with a block groove that matches the support block, and a keel can be installed between the block groove or the second support rod and the adjacent side of the U-shaped bracket.

[0016] Furthermore, when the first support rod is sleeved outside the second support rod, the upper part of the upright and the first support rod is provided with external threads, and at least one opposite side of the external thread section of the upright and the first support rod is provided with a connected longitudinal sliding groove. The nut is provided on the external thread section of the upright and the first support rod to limit and fix the first support rod and the second support rod.

[0017] The first support rod includes a rod body A disposed inside the upright and slidingly engaging with the upright, and a slider A disposed on the bottom of the rod body A and slidingly engaging with a longitudinal groove on the upright;

[0018] The second support rod includes a rod body B disposed inside the first support rod and slidingly engaging with the first support rod, and a slider B disposed on the bottom of the rod body B and slidingly engaging with a longitudinal groove on the first support rod;

[0019] or

[0020] When the second support rod is sleeved outside the first support rod, the upright and the first support rod are provided with external threads, and at least one opposite side of the external thread section of the upright and the first support rod is provided with a connected longitudinal sliding groove. The nut is provided on the external thread section of the upright and the first support rod to limit and fix the first support rod and the second support rod.

When the rod body D contacts the U-shaped support, the surface support structure is higher than the U-shaped support.

[0023] Furthermore, the nut component includes a nut and a rotating block disposed on the opposite side of the nut.

[0024] Compared with the prior art, the advantages of this utility model are:

[0025] I. This utility model improves construction efficiency by setting an adjustable support head on the upright. When it is necessary to fix the keel, fix the shaping plate, or simultaneously remove the support early and late, the adjustable support head can be freely switched. This avoids the problem of too many types of support, which can easily lead to errors in equipment or confusion during installation.

[0026] II. The adjustable support head in this utility model adjusts the U-shaped bracket 6 and the flat support 7 on the first and second support rods to rise or fall synchronously by adjusting the nut on the upright. It also adjusts the flat support on the second support rod to rise or fall by adjusting the nut on the first support rod. When it is necessary to fix the keel, fix the shaping plate, or remove the support early and late at the same time, the corresponding nut can be adjusted to make the U-shaped bracket and flat support on the first and second support rods meet the usage requirements. This effectively avoids the problem of having too many types of support, which can easily lead to errors in equipment or confusion during installation. This improves construction efficiency and is easy to operate.

[0027] Third, this utility model limits the first support rod to be sleeved outside the second support rod or the second support rod to be sleeved outside the first support rod, and provides corresponding structural limitations for the U-shaped bracket and the flat support. The purpose is to facilitate the U-shaped bracket and the flat support to be used independently for support, as well as to be used in conjunction with each other for support. When used in conjunction with each other, the U-shaped bracket can be removed early, and the keel installed on the U-shaped bracket can be removed, etc.

[0028] Fourth, the surface support structure of this utility model is simple, and when the U-shaped support is used simply, its upper surface can be located on the same horizontal plane as the inner bottom plane of the U-shaped support, so as to increase the support area;

[0029] V. When the first support rod is sleeved outside the second support rod, the planar support includes multiple sets of opposing support blocks, and the U-shaped bracket is provided with a block groove that cooperates with the support blocks. This not only helps to increase the support area of ​​the planar support, but also helps to store the U-shaped bracket in the block groove when only the U-shaped bracket is used, so as to avoid affecting the use of the U-shaped bracket.

[0045] Example 1

[0046] To address the problem that existing technologies cannot freely switch between keel fixing, shaping plate fixing, or simultaneous early and late removal of supports, thus requiring different support structures, leading to an excessive number of types, errors in equipment selection, and confusion during installation, thereby affecting construction efficiency. For example... Figure 1-6 As shown, an early stripping formwork support device for floor slab structures is provided, including an adjustable base, a starting rod set on the adjustable base, a sweeping rod connected to two adjacent starting rods, and a vertical rod 1 set on the starting rod, with a horizontal bar installed on the two adjacent vertical rods 1. An adjustable support head 2 is installed on the vertical rod 1 to freely switch between fixing the keel, fixing the shaping plate, or simultaneously requiring early stripping and late stripping support.

[0047] In practice, after installing the adjustable base, the support blocks on the adjustable base are adjusted to the same horizontal height. Then, the starting rod is installed, followed by the sweeping rod and the upright with the adjustable support head 2 on the adjacent starting rod. Horizontal bars (and diagonal bars can also be installed on the two adjacent uprights 1) are then installed. After installation, depending on the usage requirements, such as fixing only the keel, only fixing only the shaping plate on the keel, or simultaneously requiring early and late removal of supports to support the keel and shaping plate, the adjustable support head 2 can be adjusted before installing the keel and shaping plate. After installation, concrete is poured. After pouring, the supports are removed or retained as needed. This embodiment, by setting adjustable support heads on the uprights, allows for free switching between the adjustable support heads when fixing the keel, the shaping plate, or simultaneously requiring early and late removal of supports. This avoids the problems of needing to use different structures for support, which can easily lead to errors due to excessive equipment or confusion during installation, thereby improving construction efficiency.

[0048] Example 2

[0049] Based on Embodiment 1, the adjustable support head 2 includes a first support rod 3 that slides longitudinally with the upright 1, a second support rod 4 that slides longitudinally with the first support rod 3, and a nut 5 that is threadedly engaged with the upright 1 and the first support rod 3 to provide positioning support for the first support rod 3 and the second support rod 4. The first support rod 3 and the second support rod 4 are respectively provided with cooperating U-shaped supports 6 and planar supports 7. The nut 5 includes a nut 25 and a rotating block 26 disposed on the opposite side of the nut 25.

[0050] In practice, the adjustable support head adjusts the first and second support rods by rotating the nuts on the uprights to push or release them, causing the first support rod to slide longitudinally. This allows the U-shaped bracket 6 and the flat support 7 on the first support rod to rise or fall synchronously. Similarly, adjusting the nuts on the first support rod pushes or releases them to push or release the second support rod, causing it to slide longitudinally. When it is necessary to fix the keel, fix the shaping plate, or simultaneously remove the support early and late, the corresponding nuts can be adjusted to ensure that the U-shaped bracket and flat support on the first and second support rods meet the usage requirements. This effectively avoids the problems of needing to use different structures for support, which can easily lead to errors in equipment or confusion during installation. This improves construction efficiency and makes operation convenient.

[0051] Example 3

[0052] Based on Embodiment 2, when the first support rod 3 is sleeved outside the second support rod 4, the U-shaped bracket 6 consists of two L-shaped structures 8 set on opposite sides of the first support rod 3. The planar support 7 cooperates with the two L-shaped structures 8 on the second support rod 4. A keel can be installed between the L-shaped structures on the same side and the planar support 7. The planar support 7 includes multiple sets of opposing support blocks 12 set on one side of the top of the second support rod 4 and whose top surface is on the same horizontal plane as the top surface of the second support rod 4. The U-shaped bracket 6 at the corresponding position of the support block 12 is provided with a block groove 13 that cooperates with the support block 12, and a keel can be installed between the block groove 13 or the adjacent side of the second support rod 4 and the U-shaped bracket 6.

[0053] When the first support rod 3 is sleeved outside the second support rod 4, the upper part of the upright rod 1 and the first support rod 3 is provided with external threads 14, and at least one opposite side of the external thread 14 section of the upright rod 1 and the first support rod 3 is provided with a connected longitudinal sliding groove 15. The nut 5 is provided on the external thread section of the upright rod 1 and the first support rod 3 to limit and fix the first support rod 3 and the second support rod 4.

[0054] The first support rod 3 includes a rod body A17 disposed inside the upright rod 1 and slidingly engaged with the upright rod 1, and a slider A18 disposed on the bottom of the rod body A17 and slidingly engaged with the longitudinal groove 15 on the upright rod 1.

[0055] The second support rod 4 includes a rod body B19 disposed inside the first support rod 3 and slidingly engaged with the first support rod 3, and a slider B20 disposed on the bottom of the rod body B19 and slidingly engaged with the longitudinal groove 15 on the first support rod 3.

[0056] In practice, initially, the support block 12 is placed in the slot 13 and is not higher than the slot 13. When the overall height of the adjustable support head does not meet the requirements, the first and second support rods are adjusted by rotating the nut 5 on the upright 1 to push or release the longitudinal sliding of the first support rod, thus raising or lowering them. This allows the U-shaped support 6 and the flat support 7 to rise or fall synchronously. This allows for the use of the U-shaped support 6 (i.e., the U-shaped support formed by two L-shaped structures), where the upper surface of the flat support 7 is lower than the upper surface of the inner bottom of the U-shaped support, or where the upper surface of the flat support 7 is at the same level as the upper surface of the inner bottom of the U-shaped support. The keel can be fixed; or when only the panel support is needed to fix the shaping plate, the nut 5 on the first support rod can be adjusted to push the second support rod to slide longitudinally and adjust the second support rod to rise, so that the panel support is higher than the U-shaped support 6 to support the shaping plate; or while the panel support is higher than the U-shaped support 6 to support the shaping plate, the keel can be installed through the gap formed by the block groove 13 or the second support rod 4 and the adjacent side of the U-shaped support 6. When it is necessary to remove the keel early, the two nuts 5 can be rotated in opposite directions at the same time to ensure that the height of the panel support remains unchanged. In practice, the positioning auxiliary parts can be used to confirm that the two nuts 5 rotate in opposite directions at the same distance.

[0057] or

[0058] When the second support rod 4 is sleeved outside the first support rod 3, the U-shaped support 6 is an integral U-shaped structure set on the first support rod 3. The planar support 7 includes a surface support structure 16 set on the second support rod 4 on both sides of the side opening of the U-shaped support 6. A keel can be installed between the surface support structure 16 on the same side and the U-shaped support 6. The surface support structure 16 includes a bottom support 9 set on the second support rod 4, a vertical support 10 set on the bottom support 9, and a top support 11 set on the vertical support 10; a keel can be installed between the top support 11 or the vertical support 10 on the same side and the U-shaped support 6.

[0059] When the second support rod 4 is sleeved outside the first support rod 3, the upright rod 1 and the first support rod 3 are provided with external threads 14, and at least one opposite side of the external thread 14 section of the upright rod 1 and the first support rod 3 is provided with a connected longitudinal sliding groove 15. The nut 5 is provided on the external thread section of the upright rod 1 and the first support rod 3 to limit and fix the first support rod 3 and the second support rod 4.

[0060] The first support rod 3 includes a rod body C21 sleeved on the outside of the upright rod 1 and slidingly engaged with the upright rod 1, and a slider C22 disposed on the bottom of the rod body C21 and slidingly engaged with the longitudinal sliding groove 15 on the upright rod;

[0061] The second support rod 4 includes a rod body D23 sleeved outside the first support rod 3 and slidingly engaged with the first support rod 3, and a slider D24 disposed on the bottom of the rod body D23 and slidingly engaged with the longitudinal groove 15 on the first support rod 3. When the rod body D23 contacts the U-shaped support 6, the surface support structure 16 is higher than the U-shaped support 6.

[0062] In practice, initially, the top support 11 is not higher than the block groove 13. When the overall height of the adjustable support head does not meet the requirements, the first and second support rods are adjusted by rotating the nut 5 on the upright 1 to push or release the longitudinal sliding of the first support rod, thus raising or lowering them. This allows the U-shaped support 6 and the flat support 7 on them to rise or fall synchronously. Alternatively, the top support 11 can be used to fix the keel when its upper surface is lower than the inner bottom surface of the U-shaped support or when the upper surface of the top support 11 is at the same level as the inner bottom surface of the U-shaped support. The latter can also increase the support area; or, if only the surface support is needed... When the support is used to fix the shaping plate, the nut 5 on the first support rod can be adjusted to push the second support rod to slide longitudinally and adjust the second support rod to rise, so that the panel supports are higher than the U-shaped support 6 to support the shaping plate; or while the panel supports are higher than the U-shaped support 6 to support the shaping plate, the keel is installed through the gap formed by the top support 11 or the vertical support 10 and the adjacent side of the U-shaped support 6. When it is necessary to remove the keel early, the two nuts 5 can be rotated in opposite directions at the same time to ensure that the height of the panel supports remains unchanged. In practice, positioning auxiliary parts (such as the specified position of the clamp for rotation spacing limit) can be used to confirm that the two nuts 5 rotate in opposite directions at the same distance.
