Description

Technical Field

[0001] The utility model relates to the field of building construction technology, and particularly relates to a post-cast strip support device. Background Art

[0002] According to the design or construction specification requirements, post-cast strips need to be set. The concrete strips left at the corresponding positions of the foundation slab, wall and beam are the commonly said post-cast strips. During the construction process of the post-cast strip, it is necessary to rely on the corresponding support structure to abut against the ground and the bottom of the precast slab of the post-cast strip.

[0003] The existing support structure is assembled by a large number of steel pipes into a steel pipe fastener support structure. When encountering high-intensity damages such as earthquakes, it is very difficult for the steel pipe fastener support structure to return to the usable requirements after deformation. Generally, a new steel pipe fastener support structure needs to be reassembled. The assembly process of the steel pipe fastener support structure is cumbersome, the assembly time is long, the construction period of the project is delayed for a long time, and the economic benefits of the project are affected. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing steel pipe fastener support structure is very difficult to return to the usable requirements after being damaged by external forces, and a new steel pipe fastener support structure needs to be remade, resulting in a long delay in the construction period. The purpose is to provide a post-cast strip support device, which only needs to replace the deformed parts during maintenance, and relieve the force that makes the support plate tilt, so that under the action of the pneumatic support, the support plate can quickly return to the state of being vertically connected to the rectangular support column, improving the efficiency of repairing the support structure.

[0005] The utility model is realized by the following technical solutions:

[0006] A post-cast strip support device includes support columns, end columns, two support plates and at least two pneumatic supports. The two ends of the support column are respectively detachably connected to the end columns; the two support plates are respectively detachably connected to the corresponding end columns through a strengthening structure; the base of the pneumatic support is connected to the corresponding end column, and the free end of the piston rod is connected to the corresponding support plate.

[0007] The utility model adopting the above scheme detachably connects the two ends of the main column with the end columns respectively, and also detachably connects the two support plates with the corresponding end columns through a strengthening structure, which is convenient for only replacing the damaged and deformed components when deformed by external force damage, instead of replacing the whole steel pipe fastener support device, shortening the repair period; and connects the base of the pneumatic support to the corresponding end column, and the free end of the piston rod is connected to the corresponding support plate, which is convenient for the support device to compress and absorb part of the kinetic energy by the pneumatic support when subjected to external force, so as to reduce the deformation degree of the support device, and when the support plate is tilted due to external force, by removing the force that causes the support plate to tilt, the support plate can quickly return to the state of being vertically connected to the rectangular column under the action of the restoring force of the pneumatic support, improving the efficiency of repairing the support structure and reducing the project duration delay.

[0008] In some embodiments, the strengthening structure includes a plurality of angle steels, and the two sides of the angle steel are detachably connected to the corresponding support plate and end column respectively. By arranging the angle steel to connect the support plate and the end column, the strength and stiffness of the connection point are ensured, and by detachably connecting the support plate and the end column, it is convenient for replacement and maintenance, and the repair period of the support device is shortened.

[0009] In some embodiments, mounting holes are respectively arranged on the two sides of the angle steel, and a plurality of bolts respectively pass through the corresponding mounting holes and are connected to the corresponding support plate or the corresponding end column. By arranging bolts to connect the angle steel with the support plate and the end column, convenient disassembly is realized on the basis of ensuring the connection strength, and further the repair period of the support device is shortened.

[0010] In some embodiments, the strengthening structure further includes a plurality of stiffeners, the cross section of the stiffener is in an L shape, and the stiffener is attached and connected to the inner side of the corresponding angle steel. By attaching and connecting the stiffener to the inner side of the angle steel, the strength and stiffness of the angle steel are increased, and further the connection strength and stiffness between the support plate and the end column are increased.

[0011] In some embodiments, through holes are respectively arranged on the two sides of the stiffener, the plurality of through holes are respectively aligned with the corresponding mounting holes on the angle steel, and a plurality of bolts respectively pass through the corresponding through holes and mounting holes in sequence and are connected to the corresponding support plate or the corresponding end column. By bolts, the stiffener and the angle steel are overlapped and connected to the support plate and the end column, which is convenient for disassembly and maintenance.

[0012] In some embodiments, an energy dissipation member is further included, and the two ends of the column are detachably connected to the corresponding end column through the energy dissipation member. Since the column may be bent after the support device is subjected to external force, resulting in the failure of the support device, for this reason, the column is connected to the end column through the energy dissipation member. When subjected to external force, the energy dissipation member effectively absorbs and dissipates energy, protects the column by sacrificing the energy dissipation member (simple structure and low cost) to prevent the column (high cost) from deforming, and reduces the economic loss.

[0013] In some embodiments, the energy-consuming member is integrally plate-shaped, the strut is integrally rectangular column-shaped, and the energy-consuming member is adhesively connected to the sides of the strut and the end column. Since the strength of the plate-shaped structure is lower than that of the column-shaped structure with the same width, the energy-consuming member is arranged as a plate and adhesively connected to the sides of the strut and the rectangle to connect the strut and the end column. When encountering external force damage, the supporting plate with lower strength deforms to absorb the external force to protect the column-shaped strut and end column.

[0014] In some embodiments, there are multiple energy-consuming members, and corresponding energy-consuming members are connected to the opposite sides of the same strut and end column. The width of the energy-consuming member, the width of the corresponding side of the strut, and the width of the corresponding side of the end column are all the same. The energy-consuming members are connected to the opposite sides of the strut and the end column, and the width of the energy-consuming member is increased as much as possible to ensure the strength and stiffness of the connection point between the strut and the end column to meet the strength required for daily work.

[0015] In some embodiments, several energy-consuming holes are provided on the energy-consuming member, and the energy-consuming holes are evenly distributed on the energy-consuming member. By providing the energy-consuming holes, it is convenient for the energy-consuming member to deform regularly along the energy-consuming holes to protect the strut and the end column.

[0016] In some embodiments, the energy-consuming holes are long strip-shaped through holes, which are convenient for processing.

[0017] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0018] 1. By detachably connecting the two ends of the main column to the end column respectively, and also detachably connecting the two support plates to the corresponding end columns through the strengthening structure, when the deformation occurs due to external force damage, only the damaged parts can be replaced instead of replacing the whole steel pipe fastener support device, shortening the repair cycle.

[0019] 2. Connect the base of the pneumatic support to the corresponding end column, and connect the free end of the piston rod to the corresponding support plate. When the support device is subjected to external force, the pneumatic support compresses to absorb part of the kinetic energy to reduce the deformation degree of the support device. When the support plate tilts due to external force, by removing the force that causes the support plate to tilt, the support plate quickly returns to the state of being vertically connected to the rectangular strut under the action of the reset force of the pneumatic support, improving the efficiency of repairing the support structure to reduce the project duration delay.

[0020] 3. Adhesively connect the stiffening rib to the inner side of the angle steel to increase the strength and stiffness of the angle steel, and further increase the connection strength and stiffness between the support plate and the end column.

[0021] 4. Connect the strut and the end post through an energy-dissipating component. When an external force is applied, the energy-dissipating component effectively absorbs and dissipates energy, protecting the strut by sacrificing the energy-dissipating component (with simple structure and low cost) to prevent the strut (with high cost) from deforming and reducing economic losses.

[0033] This embodiment provides a post-cast strip support device, as Figures 1-4 shown, which includes a pillar 6, an end column 7, two support plates 1 and at least two pneumatic supports 4. The two ends of the pillar 6 are respectively detachably connected to the end column 7; the two support plates 1 are respectively detachably connected to the corresponding end column 7 through a strengthening structure; the base of the pneumatic support 4 is connected to the corresponding end column 7, and the free end of the piston rod is connected to the corresponding support plate 1, and the support plate 1 is supported by the pneumatic support 4. It is convenient to only replace the damaged and deformed parts when deformed due to external force damage, instead of replacing the whole steel pipe fastener support device, thereby shortening the repair cycle. When the support device is subjected to external force, the pneumatic support 4 compresses to absorb part of the kinetic energy to reduce the deformation degree of the support device, and when the support plate 1 tilts due to external force, by releasing the force that causes the support plate 1 to tilt, the support plate 1 quickly returns to the state where the support plate 1 is perpendicularly connected to the rectangular pillar 6 under the action of the restoring force of the pneumatic support 4, improving the efficiency of repairing the support structure so as to reduce the construction period delayed by the project.

[0034] As Figures 1-4 shown, the strengthening structure includes a plurality of angle steels 3, and the two sides of the angle steel 3 are respectively detachably connected to the corresponding support plate 1 and end column 7. By arranging the angle steel 3 to connect the support plate 1 and the end column 7, the strength and stiffness of the connection point are ensured, and by detachably connecting the support plate 1 and the end column 7, it is convenient for replacement and maintenance, and the cycle of repairing the support device is shortened.

[0035] As Figures 1-4 shown, mounting holes are respectively arranged on the two sides of the angle steel 3, and a plurality of bolts 8 respectively pass through the corresponding mounting holes and are connected to the corresponding support plate 1 or the corresponding end column 7. By arranging the bolts 8 to connect the angle steel 3 with the support plate 1 and the end column 7, convenient disassembly is realized on the basis of ensuring the connection strength, and further the cycle of repairing the support device is shortened.

[0036] As Figures 2-4 shown, the strengthening structure further includes a plurality of stiffeners 2. The cross-section of the stiffener 2 is in an L shape, and the stiffener 2 is attached and connected to the inner side of the corresponding angle steel 3. By attaching and connecting the stiffener 2 to the inner side of the corresponding angle steel 3, the strength and stiffness of the angle steel 3 are increased, and further the connection strength and stiffness between the support plate 1 and the end column 7 are increased.

[0037] As Figures 2-4 shown, through holes are provided on both sides of the stiffener 2. A plurality of the through holes are respectively aligned with corresponding mounting holes on the angle steel 3. A plurality of bolts 8 respectively pass through the corresponding through holes and mounting holes in sequence and then are connected to the corresponding support plate 1 or the corresponding end column 7. The stiffener 2 and the angle steel 3 are overlapped and connected to the support plate 1 and the end column 7 through the bolts 8, which is convenient for disassembly and maintenance.

[0038] As Figure 1 and Figure 2 shown, it further includes an energy dissipation member 5. Both ends of the strut 6 are detachably connected to the corresponding end column 7 through the energy dissipation member 5. Since the strut 6 may be bent after the support device is subjected to an external force, resulting in the failure of the support device, for this reason, the strut 6 is connected to the end column 7 through the energy dissipation member 5. When subjected to an external force, the energy dissipation member 5 (with a simple structure and low cost) is sacrificed to protect the strut 6, preventing the strut 6 (with a high cost) from deforming and reducing economic losses.

[0039] As Figure 1 and Figure 2 shown, the energy dissipation member 5 is integrally in a plate shape, the strut 6 is integrally in a rectangular column shape, and the energy dissipation member 5 is attached and connected to the sides of the strut 6 and the end column 7. Since the strength of the plate structure is lower than that of the columnar structure with the same width, for this reason, the energy dissipation member 5 is set in a plate shape and attached and connected to the sides of the strut 6 and the rectangle, connecting the strut 6 and the end column 7. When encountering external force damage, the external force is absorbed by the deformation of the support plate 1 with low strength to protect the columnar strut 6 and end column 7.

[0040] Specifically, connection holes are provided on the energy dissipation member 5. Bolts pass through the connection holes and are connected to the threaded holes on the strut 6 or the threaded holes on the end column 7, which is convenient for replacing and disassembling the energy dissipation member 5. The two ends of the energy dissipation member 5 can also be welded to the strut 6 and the end column 7 respectively.

[0041] As Figure 1 and Figure 2As shown, there are multiple energy-consuming members 5, and corresponding energy-consuming members 5 are connected to opposite sides of the same pillar 6 and end column 7. The width of the energy-consuming member 5, the width of the corresponding side surface of the pillar 6, and the width of the corresponding side surface of the end column 7 are the same. Connect the energy-consuming member 5 to opposite sides of the pillar 6 and end column 7, and increase the width of the energy-consuming member 5 as much as possible to ensure the strength and stiffness of the connection point between the pillar 6 and end column 7 to meet the strength required for daily work.

[0042] As Figure 1 and Figure 2 shown, several energy-consuming holes are provided on the energy-consuming member 5, and the energy-consuming holes are evenly distributed on the energy-consuming member 5. By providing the energy-consuming holes, it is convenient for the energy-consuming member 5 to deform regularly along the energy-consuming holes to protect the pillar 6 and end column 7. The energy-consuming holes are long strip through holes, which are convenient for processing.

[0043] The angle steel 3, energy-consuming member 5, and end column 6 in the present utility model are all made of Q345 steel. The pneumatic support 4 is made of 40Cr steel. The support plate is made of a plate-like member capable of supporting the post-cast strip, such as a metal plate and a high-strength plastic plate, etc. The bolt 8 is a bearing type high-strength bolt.

[0044] The above specific implementation manners have further detailed the purpose, technical solution, and beneficial effects of the present utility model. It should be understood that the above is only the specific implementation manner of the present utility model and is not used to limit the protection scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
