Description

Technical Field

[0001] The present application relates to the field of housing supports, and in particular to an adjustable elastic support. Background Art

[0002] Because some ancient buildings have existed for a long time, they have suffered a certain degree of damage and require restoration. Some buildings have roofs on top, but their safe service life has expired and they are at risk of collapse. Therefore, prior to restoration, these roofs need to be lifted. Prior to restoration, there are existing structures for lifting the flat roofs of building structures.

[0003] Regarding the above-mentioned related technologies, the inventor believes that since the upper covers of some building bodies are large-span reinforced concrete thin-shell vaults, the special shape of the vault of the arch structure makes the external force better than the internal force, and it is easy for the internal part of the vault to pass through when lifting. Therefore, the control of force needs to be very precise, and the flat lifting structure cannot accurately control the lifting force, which makes it easy for the vault to be broken when lifting the vault.

[0007] By adopting the above technical solution, in the initial state, the elastic member is in a free state and is only affected by the gravity of the upper support body, which causes the elastic member to be compressed to a certain extent. After the upper support body is completely contacted and fixed with the arch, the height of the bottom end of the elastic member is adjusted by the positioning assembly, and the elastic member is compressed. The upper end of the elastic member is stationary due to its connection with the support body. When the elastic member is compressed to a predetermined length, the size of the lifting force can be known by observing the upward movement distance of the lower end of the elastic member, which facilitates precise control.

[0011] By adopting the above technical solution, the height of the customized screw rod in the support rod can be adjusted by rotating the customized nut, thereby adjusting the height of the connecting assembly.

[0012] Optionally, the outer sleeve is provided with a limiting groove for the limiting rod to slide, and a scale line is provided on the outer side of the outer sleeve at a position corresponding to the limiting groove.

[0013] By adopting the above technical solution, the limiting groove can limit the sliding of the limiting rod, thereby improving the stability of the limiting rod when moving, and the setting of the scale line makes it easy to observe the extension and contraction length of the elastic member.

[0014] Optionally, an inner sleeve is provided on the limiting rod and inside the outer sleeve, and the elastic member is sleeved on the outside of the inner sleeve.

[0015] By adopting the above technical solution, a certain guiding effect can be played on the elastic member, making the elastic member less likely to bend.

[0016] Optionally, the connection assembly includes a hinged seat arranged on the top plate, an anti-slip pad arranged on the hinged seat, and an adhesive plate arranged on the anti-slip pad, and the adhesive plate is connected to the arch.

[0029] The following is combined with Figures 1 to 3 This application is described in further detail.

[0030] The embodiment of the present application discloses an adjustable elastic support. Figure 1The adjustable elastic support top includes a supporting body 1, a lifting mechanism 2 and a supporting top body 3. The supporting body 1 serves as the basis of the entire elastic support top. The supporting body 1 can be installed on the building surface or platform according to actual conditions. The lifting mechanism 2 is installed on the supporting body 1. The supporting top body 3 is slidably connected to the top of the supporting body 1 through the lifting mechanism 2, and the supporting top body 3 is used to connect with the arch 4.

[0031] Reference Figure 2 The support body 1 includes a base 11 and an outer sleeve 12. The outer sleeve 12 is vertically welded to the top of the base 11. The lifting mechanism 2 includes a positioning assembly 21 and an elastic member 22. The positioning assembly 21 is installed between the base 11 and the outer sleeve 12. The elastic member 22 is installed on the positioning assembly 21. The positioning assembly 21 is used to adjust the bottom height of the elastic member 22. The top end of the elastic member 22 is connected to the bottom of the support body 3. In this embodiment, the elastic member 22 is a spring.

[0032] The positioning assembly 21 includes a connecting plate 211, a plurality of positioning screws 212, a limiting rod 213 and a positioning nut 214. The connecting plate 211 is horizontally fixed to the outside of the outer sleeve 12. The plurality of positioning screws 212 are installed between the base 11 and the connecting plate 211. In this embodiment, the number of the positioning screws 212 is four. The outer side of the positioning screw 212 and the inner thread of the base 11 are connected with a lower nut 215. The outer side of the positioning screw 212 and the top of the connecting plate 211 are connected with an upper nut 216 to realize the installation of the positioning screw 212. The four positioning screws 212 are circumferentially arranged around the outer sleeve 12. The outer side of the outer sleeve 12 is opened. There is a limiting groove 121, which is connected to the interior of the outer sleeve 12. The limiting rod 213 is slidably connected to the limiting groove 121, and a part of the limiting rod 213 is located inside the outer sleeve 12, and a part is located outside the outer sleeve 12. A scale line 122 is provided on the outer side of the outer sleeve 12 corresponding to the position of the limiting groove 121. The positioning nut 214 is threadedly connected to the outside of the positioning screw 212, and a sliding block 217 is provided on the sliding sleeve of the outer sides of two adjacent positioning screws 212. In this embodiment, the number of sliding blocks 217 is two in total, and the two sliding blocks 217 are arranged in alignment. The sliding block 217 is located between the limiting rod 213 and the positioning nut 214.

[0033] Reference Figure 1 and Figure 2 The supporting body 3 includes a support rod 31, a top plate 32, and a connecting assembly 33. The support rod 31 is slidably connected to the top of the outer sleeve 12. The top plate 32 is mounted on the top of the support rod 31 via an adjustment assembly 34. The connecting assembly 33 is mounted on the top of the top plate 32. The connecting assembly 33 is used to connect to the arch 4. A support plate 311 is fixed to the bottom of the support rod 31, and the bottom of the support plate 311 is connected to the top of the elastic member 22.

[0034] The specific lifting steps are as follows: in the initial state, the spring is in a free state and is only affected by the gravity of the upper support rod 31, which causes the spring to be compressed to a certain extent. After the upper connecting assembly 33 is completely contacted and fixed with the arch 4, the upper end of the spring is stationary due to the connection with the support rod 31. By screwing the four positioning nuts 214 upward, a jack can be used for assistance, so that the limit rod 213 can be moved upward through the sliding block 217 to compress the spring. The limit rod 213 can move in the limit groove 121. At the same time, since the scale line 122 is located on one side of the limit groove 121, the scale line 122 can be used to measure the compressed length of the spring. The personnel can use the size of the spring to calculate the elastic coefficient k, and can accurately calculate the force applied by the support rod 31 on the arch 4, that is, the size of the supporting force, so that it is not easy to break the arch 4 when lifting the arch 4.

[0035] Preferably, an inner sleeve 218 is fixed on the top of the limiting rod 213 and inside the outer sleeve 12, and the elastic member 22 is sleeved on the outside of the inner sleeve 218. The setting of the inner sleeve 218 can play a certain guiding role on the elastic member 22, making the elastic member 22 not easy to bend.

[0036] Reference Figure 3 The adjustment component 34 includes a customized screw 341 and a customized nut 342. The top of the support rod 31 is hollow. The customized screw 341 is slidingly connected to the top of the support rod 31, and the customized nut 342 is rotatably connected to the top of the support rod 31, and the customized nut 342 is threadedly sleeved on the outside of the customized screw 341.

[0037] By rotating the custom nut 342 , the height of the custom screw rod 341 in the support rod 31 can be adjusted, thereby adjusting the height of the connecting assembly 33 .

[0038] Preferably, a vertical slot is formed on the outside of the custom screw 341, and a slider is fixed to the inside of the support rod 31, which is slidably connected to the slot. The slot and slider can limit the sliding of the support rod 31, preventing the support rod 31 from rotating, making it easier to rotate the custom screw 341 to adjust the height of the support rod 31.

[0039] The connecting assembly 33 includes a hinged seat 331, an anti-slip pad 332, and an adhesive plate 333. The hinged seat 331 is hinged to the top of the top plate 32 via a rotating member 334. The anti-slip pad 332 is fixed to the top of the hinged seat 331. The adhesive plate 333 is fixed to the top of the anti-slip pad 332, and the adhesive plate 333 is connected to the arch 4. The rotating member 334 can be a hinge, a rotating shaft, or a bolt. In this embodiment, the rotating member 334 is a bolt. It should be noted that the adhesive plate 333 can be connected to the arch 4 by adhesive steel glue. Due to the hinged arrangement between the hinged seat 331 and the top plate 32, the inclination angle of the adhesive plate 333 can be adjusted accordingly according to the angle of the arch 4, and can adapt to arches 4 in different positions.

[0040] The implementation principle of an adjustable elastic support top in the embodiment of the present application is as follows: based on the survey and analysis, the center of each adhesive plate 333 is determined. After the base 11 and the center of the adhesive plate 333 are fixed, the center of the adhesive plate 333 of the arch 4 is marked, and a circle with a diameter of 20 cm is drawn with the mark as the center. The mortar layer within the marked circle is manually cleaned with a pointed shovel, and the concrete surface of the position where the mortar layer has been cleaned is cleaned with a grinding sheet, and then scrubbed with acetone. The adhesive plate 333 is adhered to the center of the adhesive plate 333 at the bottom of the arch 4 by adhesive steel glue. It should be noted that after the adhesive plate 333 is installed, it is necessary to wait for 24 hours. Cut the support rod 31, lift the support rod 31 to the installation position for pre-installation, install the support rod 31 in the outer sleeve 12 at the top of the base 11, and then install the lifting mechanism 2 between the base 11 and the support rod 31, and connect the adhesive plate 333 to the support rod 31. After the upper supporting body 3 is completely contacted and fixed with the arch 4, the four positioning nuts 214 are screwed upwards, and a jack can be used for assistance, so that the limiting rod 213 is moved upwards through the sliding block 217 to compress the spring. The limiting rod 213 can move in the limiting groove 121. At the same time, since the scale line 122 is located on one side of the limiting groove 121, the length of the spring compression can be measured through the scale line 122. The personnel can calculate the elastic coefficient k through the size of the spring, and can accurately calculate the force applied by the support rod 31 to the arch 4, that is, the size of the supporting force, so that it is not easy to break the arch 4 when it lifts the arch 4.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
