Description

Technical Field

[0002] Post-cast strips are concrete strips set at the corresponding positions of the foundation slab, wall, and beam in accordance with the design or construction specifications to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven shrinkage or settlement. Post-cast strips temporarily divide the structure into several parts. After the internal shrinkage of the components, the construction joint concrete is poured again after a certain period of time to connect the structure into a whole. Post-cast strips can be cast with cement or concrete with a trace amount of aluminum powder in cement. Its strength grade should be one level higher than the strength of the component to prevent cracks from appearing between the new and old concretes and forming weak points.

[0003] At present, the support system of the post-casting strip usually builds the post-casting strip formwork first, then builds the post-casting strip independent support frame, and finally builds the top plate formwork. After the beams and slabs on both sides of the post-casting strip are cast, the post-casting strip formwork and the top plate formwork need to be dismantled to clean up the debris inside the post-casting strip. Moreover, before the post-casting strip is cast, the top plate formwork needs to be rebuilt.

[0036] The present application provides a construction support device.

[0037] See also Figures 1 to 4 In one embodiment of the present application, the construction support device includes a lower support member 1 and an upper support member 2, the lower support member 1 is provided with a hollow structure 11 inside, and the hollow structure 11 is used to fill particulate matter to a preset height; the lower support member 1 is provided with a first discharge structure 12, and the first discharge structure 12 is used to discharge the particulate matter in the hollow structure 11; the upper end of the upper support member 2 is provided with a support structure 21, and the support structure 21 is used to abut against the structural surface 3; the lower end of the upper support member 2 is inserted into the hollow structure 11 and abuts against the top of the particulate matter.

[0038] A hollow structure 11 is provided inside the lower supporting member 1, and the hollow structure 11 is used to fill granular matter to a preset height, and the lower end of the upper supporting member 2 is inserted into the hollow structure 11 and abutted against the top of the granular matter, while the supporting structure 21 at the upper end of the upper supporting member 2 is used to abut against the structural surface 3, so that the construction support device provides support for the structural surface 3; by filling the hollow structure 11 with granular matter to a preset height, the overall length of the construction support device can be adjusted by changing the preset height; when disassembly is required, part of the granular matter in the hollow structure 11 is discharged by the first discharge structure 12, so that the upper supporting member 2 sinks and is separated from the structural surface 3, and then the construction support device can be removed.

[0039] That is, a hollow structure 11 is provided inside the lower support member 1, and the hollow structure 11 is used to fill particles to a preset height. When the upper support member 2 is inserted into the hollow structure 11 and abuts against the top of the particles, the length of the entire support device is adjusted by changing the preset height to meet the support requirements of different heights. Among them, the particles can be gravel, sand, gravel, etc. Filling the particles in the hollow structure 11 of the lower support member 1 can improve the structural strength. The particles are discharged from the hollow structure 11 through the first discharge structure 12, which can adjust the support height of the structural surface 3 and facilitate the disassembly of the construction support device. Specifically, when the support device needs to be disassembled, the particles in the hollow structure 11 can be discharged through the first discharge structure 12, so that the upper support member 2 sinks, thereby achieving separation from the structural surface 3, simplifying the disassembly process. By quickly adjusting and disassembling the support device, the construction efficiency can be improved and the construction time can be reduced. The reusability of the construction support device reduces material waste during the construction process and helps to achieve green construction. And because of the high adjustability and reusability of the supporting device, the material cost and rental fee can be reduced, the economic benefit can be improved, and the economic benefit of the building construction can be improved.

[0040] The construction support device has a strong structural strength, which can reduce the deformation of the support formwork of large-volume concrete formwork projects, thereby improving the quality of concrete structure construction. Using the construction support device in the concrete structure parts that need to be supported for a long time can significantly improve the on-site material turnover rate, reduce material consumption, and reduce material rental costs.

[0041] In one embodiment, the first discharge structure 12 includes a first through hole and a first blocking component, wherein the first through hole is provided on the side wall of the lower support member 1; the first through hole is connected to the hollow structure 11, and the first blocking component is used to block the first through hole. By using the first blocking component, the first through hole can be blocked and opened, and the construction personnel can easily control the filling and discharge of the particles in the hollow structure 11; the first through hole is connected to the hollow structure 11 to ensure that the particles can be directly discharged from the hollow structure 11 to the outside; wherein, the first blocking component is used to block the first through hole so that the hollow structure 11 can be smoothly filled with particles; the first through hole is provided on the side wall of the lower support member 1, which is convenient for the construction personnel to open the first blocking component to ensure that the particles can be smoothly discharged.

[0042] In one embodiment, the distance between the first through hole and the upper end of the lower support member 1 is greater than or equal to the length of the upper support member 21; the diameter of the first through hole ranges from 20 mm to 30 mm. By making the distance between the first through hole and the upper end of the lower support member 1 greater than or equal to the length of the upper support member 21, it can be ensured that the upper support member 21 will not hinder the flow of particulate matter when discharging particulate matter; at the same time, not all particulate matter will be discharged, which helps to maintain the overall structural strength of the lower support member 1. The first through hole is located on the side wall of the lower support member 1, and its diameter ranges from 20 mm to 30 mm. This size range ensures that the particulate matter can be discharged smoothly, while avoiding the blockage problem that may be caused by too small a diameter. Among them, the diameter of the first through hole can be 26 mm.

[0043] In one embodiment, the first plugging assembly includes a first screw and a first nut, the first nut is fixedly connected to the lower support member 1, and the first nut is concentrically arranged with the first through hole; the first screw is threadedly connected with the first nut. The first nut is fixedly connected with the lower support member 1, ensuring the stability and firmness of the first plugging assembly during operation. The first nut is concentrically arranged with the first through hole, that is, the center of the first nut is aligned with the center of the first through hole, which helps to achieve precise plugging and opening operations. The threaded first screw and the first nut cooperate to provide a good plugging effect and prevent particulate matter from being discharged when needed.

[0044] In one embodiment, the lower support member 1 is further provided with a second discharge structure 13, which is provided at the lower end of the lower support member 21, and is used for drainage. When the filled granular material is gravel, water can be added to the interior of the hollow structure 11, and the addition of water can reduce the gaps between the gravel to increase the density of the gravel. The dense gravel can provide a stronger bearing capacity, thereby increasing the support force and stability. When water is not needed, the second discharge structure 13 can be used to discharge excess water.

[0045] In one embodiment, the second discharge structure 13 includes a second through hole and a second plugging component, wherein the second through hole is provided on the side wall of the lower support member 1; the second through hole is connected to the hollow structure 11, and the second plugging component is used to plug the second through hole. The second through hole is connected to the hollow structure 11, and the first through hole can be plugged and opened by using the first plugging component, so as to ensure that the water inside can be directly discharged from the hollow structure 11 to the outside; and the second through hole is provided at the lower part of the lower support member 1, so as to facilitate the operation of the construction personnel and ensure that the water can be discharged smoothly; wherein, the first plugging component is used to plug the first through hole, so that the hollow structure 11 can be smoothly filled with particles.

[0046] In one embodiment, the width of the upper support member 2 is smaller than the width of the hollow structure 11. The above structure can ensure that the upper support member 2 can be inserted into the hollow structure 11, that is, the narrower upper support member 2 is easier to insert into the wider hollow structure 11, or to be pulled out from the wider hollow structure 11.

[0047] In one embodiment, the upper support member 2 and the lower support member 1 are both made of steel material. The steel material has high strength and rigidity, can withstand large loads, and is not easily deformed, thereby ensuring the reliability of the upper support member 2 and the lower support member 1. Specifically, the upper support member 2 is welded into a whole by a steel-plated steel pipe with a specification of DN100 (nominal diameter of 100 mm) and a support plate with a specification of 200 (length) * 200 (width), and the support plate directly contacts the structural surface 3. The lower support member 1 is welded into a whole by a steel-plated steel pipe with a specification of DN120 (nominal diameter of 120 mm) and a base 14 with a specification of 200 (length) * 200 (width).

[0048] In one embodiment, the second plugging assembly includes a second screw and a second nut, the second nut is fixedly connected to the lower support member 1, and the second nut is concentrically arranged with the second through hole; the second screw is threadedly connected with the second nut. The second nut is fixedly connected with the lower support member 1, ensuring the stability and firmness of the second plugging assembly during operation. The second nut is concentrically arranged with the second through hole, that is, the center of the second nut is aligned with the center of the second through hole, which helps to achieve precise plugging and opening operations. The threaded second screw and the second nut can fit tightly, provide a good sealing effect, and prevent water from being discharged when needed.

[0049] In one embodiment, the diameter of the second through hole ranges from 10 mm to 15 mm. When the diameter of the second through hole is controlled within a range of 10 mm to 15 mm, the second through hole can have sufficient drainage capacity while avoiding the loss of particles due to an overly large hole diameter. The diameter of the second through hole can be set to 12 mm.

[0050] In one embodiment, a base 14 is provided at the lower end of the lower support member 1. The base 14 can increase the contact area between the lower support member 1 and the ground, thereby improving the stability of the overall structure. The base 14 helps to disperse the weight of the lower support member 1, reduce the risk of ground sinking or deformation, adapt to different ground conditions, such as uneven or soft ground, and provide more uniform support.

[0051] In one embodiment, the support structure 21 includes a support plate, and the support plate is fixed to the upper support member 2 by welding. By welding and fixing the support plate to the upper support member 2, the connection between the support plate and the upper support member 2 can be made stronger to withstand a larger load and not easy to loosen.

[0052] In one embodiment, the upper end of the lower support member 1 is provided with an opening 15, and the opening 15 is surrounded by an extension 16. When the upper support member 2 is inserted into the hollow structure 11, the extension 16 has a guiding function, helping the upper support member 2 to align with the hollow structure 11 and guiding the upper support member 2 to be smoothly inserted into the hollow structure 11. In addition, the extension 16 can increase the force-bearing area of ​​the lower opening 15, reduce the possibility of deformation of the opening 15 due to concentrated force, and improve the stability and durability of the structure.

[0053] In one embodiment, a plurality of first reinforcing ribs are arranged around the connection between the base 14 and the lower support member 1; a plurality of second reinforcing ribs are arranged around the connection between the support plate and the upper support member 2. The first reinforcing ribs can significantly improve the strength of the connection between the base 14 and the lower support member 1, reduce the risk of damage due to force, and improve the overall bearing capacity. Similarly, the second reinforcing ribs can significantly improve the strength of the connection between the support plate and the upper support member 2, reduce the risk of damage due to force, and improve the overall bearing capacity.

[0054] Among them, the installation method of the construction support device is:

[0055] (1) Before the formwork construction, the locations where the construction support devices need to be installed are arranged. The spacing of the construction support devices can be up to 2m to 4m depending on the site conditions. After the formwork is laid, the support plate connection port of the upper support member 2 is left. The specification of the support plate connection port is 200mm (length) * 200mm (width).

[0056] (2) Continue the installation operation of the lower support member 1; first measure the length of the upper support member 2, calculate the required sand filling height inside the hollow structure 11 to obtain the preset height, and reserve 10 cm of settlement height when the lower support member 1 is filled with sand more than the preset height. Water can be added according to the density of the gravel to increase the density of the gravel, and the water can be discharged through the second drainage hole at the bottom.

[0057] (3) After the gravel is compacted, the lower end of the upper support member 2 is inserted into the hollow structure 11, and then the steel bars are tied and the concrete is poured according to the normal construction process.

[0058] In addition, the method for dismantling the construction support device is:

[0059] (1) After the concrete reaches the conditions for demolding, all materials supporting the formwork body can be removed and circulated, leaving only the construction support device to independently support the structural surface 3.

[0060] (2) When the concrete structure reaches the conditions for demolding, the construction support device is removed; during the removal, the second screw of the lower support member 1 is removed, and the particles inside the hollow structure 11 are discharged and collected. If the gravel inside the hollow structure 11 is densely packed into blocks, water can be poured into the second through hole to flush the sand to discharge it.

[0061] (3) When part of the internal particles of the hollow structure 11 are removed, the upper support member 2 can be sunk and separated from the structural surface 3 by a slight knocking type construction support device, and the demolition operation can be completed. After the upper support member 2 and the lower support member 1 are dismantled, they can be classified and packaged for recycling.

[0062] The technical solution of the application is that a hollow structure 11 is provided inside the lower supporting member 1, and the hollow structure 11 is used to fill particulate matter to a preset height, and the lower end of the upper supporting member 2 is inserted into the hollow structure 11 and abutted against the top of the particulate matter, and the supporting structure 21 at the upper end of the upper supporting member 2 is used to abut against the structural surface 3, so as to use the construction support device to provide support for the structural surface 3; by filling the hollow structure 11 with particulate matter to a preset height, the overall length of the construction support device can be adjusted by changing the preset height; when disassembly is required, the first discharge structure 12 is used to discharge part of the particulate matter in the hollow structure 11, so that the upper supporting member 2 sinks and separates from the structural surface 3, and then the construction support device can be removed.
