Description

Technical Field

[0001] This utility model relates to the field of support technology, specifically to a general-purpose prefabricated recyclable steel support for railway beam yards. Background Technology

[0002] The beam yard is a place for producing precast beam segments. After the beam segments are poured, they need to be cured outdoors to reach the predetermined strength. At present, the support and storage of beam segments are generally made by pouring concrete to make storage platforms. The cast-in-place storage platforms have high structural strength, which makes it difficult to dismantle the storage platforms after the beam yard work is completed, and it is not convenient to restore the site. Therefore, a general-purpose prefabricated recyclable steel support for railway beam yards is proposed. Utility Model Content

[0003] In order to solve the technical problems existing in the prior art, this utility model provides a general-purpose prefabricated recyclable steel support for railway beam yards.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a general-purpose prefabricated recyclable steel support for railway beam yards, including a bottom support component. A sand cylinder component is installed on the surface of the bottom support component. The sand cylinder component is used to load sand. A top support component is fitted on the top of the sand cylinder component. The top support component limits and fixes the upper end of the sand cylinder component. A pressure block is provided inside the top support component. The pressure block extends into the sand cylinder component. The pressure block presses down on the sand to shape the sand. The shaped sand bears the pressure transmitted by the top support component and transmits the pressure to the sand cylinder component and the bottom support component.

[0005] Preferably, the bottom support assembly includes a base plate and lateral limiting plates. The base plate is placed in the beam storage area of ​​the beam yard. Several sets of lateral limiting plates are welded to the surface of the base plate at equal intervals in a ring arrangement. The ring-shaped lateral limiting plates form a ring-shaped limiting area. The diameter of the ring-shaped limiting area is the same as the diameter of the sand cylinder assembly. The several sets of lateral limiting plates support and limit the lower end of the sand cylinder assembly.

[0006] Preferably, the bottom support assembly further includes a rotation limiting block, and two sets of the rotation limiting blocks are provided. The two sets of rotation limiting blocks are symmetrically arranged on both sides of the surface of the bottom support assembly, and the bottom end of the sand cylinder assembly is fitted inside the rotation limiting block.

[0007] Preferably, the sand cylinder assembly includes a sand cylinder side plate, a connecting and fixing part, and a connecting bolt. The connecting and fixing part is disposed on both sides of the bottom end of the sand cylinder side plate. The two sets of sand cylinder side plates are symmetrically fitted together, and the connecting and fixing parts at the bottom ends of the two sets of sand cylinder side plates are fitted and aligned. The connecting bolt passes through the two sets of connecting and fixing parts to connect the two sets of connecting and fixing parts and the sand cylinder side plate.

[0008] Preferably, the width of the two sets of connecting and fixing parts is the same as the inner width of the rotation limiting block, and the two sets of connecting and fixing parts are nested inside the rotation limiting block.

The sleeve limiting ring is welded to the center of the bottom end of the top plate. The inner diameter of the sleeve limiting ring is the same as the diameter of the sand cylinder assembly.

[0010] Preferably, a connecting screw is welded at the center of the bottom surface of the top plate, the pressure block is threaded to the outside of the connecting screw, and the pressure block abuts against the bottom surface of the top plate.

[0011] Preferably, the pressure block is provided in several groups, the thickness of the pressure block in the several groups increases sequentially, and the diameter of the pressure block in each group is consistent with the inner diameter of the sand cylinder assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model is provided with a support component, a sand cylinder component and a top support component. The sand cylinder component is assembled with the support component. After connection, sand is injected into the sand cylinder component. After the top support component is connected to the sand cylinder component, the downward pressure can be transferred to the sand cylinder component and the compacted sand. During dismantling, the entire device can be quickly dismantled by disassembling the sand cylinder component. This solves the problem that the high structural strength of the cast-in-place storage platform makes it difficult to dismantle the beam storage platform after the beam yard work is completed.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, highlighting the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0023] Example:

[0024] like Figure 1-5 As shown, this utility model provides a general-purpose prefabricated recyclable steel support for railway beam yards, including a bottom support component 1. A sand cylinder component 2 is installed on the surface of the bottom support component 1. The sand cylinder component 2 is used to load sand. A top support component 3 is fitted on the top of the sand cylinder component 2. The top support component 3 limits and fixes the upper end of the sand cylinder component 2. A pressure block 4 is provided inside the top support component 3. The pressure block 4 extends into the sand cylinder component 2 and presses down on the sand to shape it. The shaped sand bears the pressure transmitted by the top support component 3 and transmits the pressure to the sand cylinder component 2 and the bottom support component 1.

[0025] The bottom support assembly 1 includes a base plate 11 and a lateral limiting plate 12;

[0026] The base plate 11 is placed in the beam storage area of ​​the beam yard. Several sets of lateral limiting plates 12 are welded to the surface of the base plate 11 at equal intervals in a ring arrangement. The ring-shaped lateral limiting plates 12 form a ring-shaped limiting area. The diameter of the ring-shaped limiting area is the same as the diameter of the sand cylinder assembly 2. The several sets of lateral limiting plates 12 support and limit the lower end of the sand cylinder assembly 2. The base plate 11 transmits the pressure to the ground. The sand cylinder assembly 2 is confined within the ring-shaped limiting area to prevent the sand cylinder assembly 2 from deflecting laterally.

[0027] The bottom support component 1 also includes a rotation limit block 13. There are two sets of rotation limit blocks 13, which are symmetrically arranged on both sides of the surface of the bottom support component 1. The bottom end of the sand cylinder component 2 is fitted into the rotation limit block 13. The rotation limit block 13 can restrict the rotation of the sand cylinder component 2 and further ensure the stability of the sand cylinder component 2 in its setting state.

[0028] Sand cylinder assembly 2 includes a sand cylinder side plate 21, a connecting and fixing part 22, and a connecting bolt 23;

[0029] The connecting and fixing parts 22 are set on both sides of the bottom end of the sand cylinder side plate 21. The two sets of sand cylinder side plates 21 are symmetrically attached and form a sand and gravel holding space. The connecting and fixing parts 22 at the bottom end of the two sets of sand cylinder side plates 21 are attached and aligned. The connecting bolts 23 pass through the two sets of connecting and fixing parts 22 to connect the two sets of connecting and fixing parts 22 and the sand cylinder side plates 21. Under the constraint of the connecting bolts 23, the two sets of sand cylinder side plates 21 maintain a stable connection state. At this time, the combined two sets of sand cylinder side plates 21 are connected to the bottom support component 1.

[0030] The width of the two sets of connecting and fixing parts 22 is the same as the inner width of the rotation limiting block 13. The two sets of connecting and fixing parts 22 are nested inside the rotation limiting block 13. During the initial installation, the rotation limiting block 13 can limit the setting position of the connecting and fixing parts 22 by aligning with them, which facilitates the initial alignment when connecting the bottom support component 1 and the sand cylinder component 2.

[0031] The top support assembly 3 includes a top plate 31 and a sleeve limiting ring 32;

[0032] The top plate 31 and the bottom plate 11 have the same specifications. The sleeve limiting ring 32 is welded to the center of the bottom end of the top plate 31. The inner diameter of the sleeve limiting ring 32 is the same as the diameter of the sand cylinder assembly 2. When connecting, the sleeve limiting ring 32 can tighten and fix the upper part of the sand cylinder assembly 2, so that the top plate 31 can stably transmit the force to the sand cylinder assembly 2.

[0033] A connecting screw 33 is welded to the center of the bottom surface of the top plate 31. The pressure block 4 is threaded to the outside of the connecting screw 33 and abuts against the bottom surface of the top plate 31. Several sets of pressure blocks 4 are provided, and the thickness of the several sets of pressure blocks 4 increases sequentially. The diameter of each set of pressure blocks 4 is consistent with the inner diameter of the sand cylinder assembly 2. When the top support assembly 3 is fitted onto the upper end of the sand cylinder assembly 2, the pressure block 4 enters the interior of the sand cylinder assembly 2 along with the top support assembly 3. The pressure block 4 presses down on the sand and gravel and makes the sand grains compacted. The compacted sand grains provide reverse support for the pressure block 4. The height can be adjusted by using pressure blocks 4 of different thicknesses in conjunction with the top support assembly 3, thereby achieving support adjustment at different heights.

[0034] In use, the base plate 11 is laid flat in the support area, and the two sets of sand cylinder side plates 21 are symmetrically attached. The two sets of connecting fixing parts 22 and the sand cylinder side plates 21 are connected by connecting bolts 23 passing through the connecting fixing parts 22 at the bottom of the two sets of sand cylinder side plates 21. The assembly of the two sets of connecting fixing parts 22 is nested in the annular limiting area formed by the lateral limiting plate 12. At the same time, the connecting fixing parts 22 are inserted into the rotating limiting block 13. The connecting fixing parts 22 are restricted by the rotating limiting block 13 and move into the sand and gravel holding space. Fine sand is injected, and the pressure block 4 is connected to the connecting screw 33 at the bottom of the top support component 3. The top support component 3 is then sleeved and connected to the top of the two sets of sand cylinder side plates 21. The sleeved limiting ring 32 can tighten and fix the upper part of the sand cylinder component connection fixing part 22. When under pressure, the top plate 31 transmits pressure to the sand through the pressure block 4. The sand transmits pressure to the sand cylinder side plate 21 and the bottom plate 11. The sleeved limiting ring 32, together with the lateral limiting plate 12, supports the sand cylinder side plate 21 and maintains the assembled state of the sand cylinder component 2.

[0035] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
