Description

Technical Field

[0001] The utility model relates to the technical field of steel support bottom plates, in particular to a steel support bottom plate that can be quickly disassembled and assembled. Background Technique

[0002] A steel support bottom plate refers to a support plate used at the bottom when steel supports are used as a support method. This bottom plate is usually made of steel plates and has high strength and rigidity. It can support the support system and the reaction force at the bottom, ensuring the stability and safety of the support. Steel supports refer to using steel pipes, H-shaped steel, and angle steel to enhance the stability of engineering structures. Generally, they are inclined connecting members, and the most common shapes are herringbone and cross shapes. Because steel supports can be recycled and reused, they have the characteristics of economy and environmental protection. Steel supports are widely used in subways and foundation pit enclosures. The publication number CN211395696U discloses a steel support bottom plate for building construction, including a bottom plate. A plurality of mounting seats are fixedly connected to the top end of the bottom plate. A screw rod is threadedly connected inside the mounting seat. A sleeve is threadedly connected to the outside of the screw rod. A plurality of outer frames corresponding to the mounting seats are fixedly connected to the top end of the bottom plate. The outer frames are located outside the mounting seats. Two symmetrically distributed screw holes are opened on the outside of the outer frames. In actual use of the above technology, in order to facilitate disassembly and assembly, only one screw rod is used to penetrate and connect. During long-term use, the screw rod is easily deformed under extrusion. The steel column is slidably connected to the bottom plate, and there is only one card slot to limit it. The steel column is easily displaced, resulting in an unstable steel support structure and affecting the support effect, so improvement is needed. Content of the Utility Model

[0003] The purpose of the utility model is to solve the technical problems raised in the above background technique.

[0004] The utility model adopts the following technical scheme: A steel support bottom plate that can be quickly disassembled and assembled, including a bottom plate body. A fixing block is fixedly installed on the surface of the bottom plate body. A first connection disk is fixedly installed on the surface of the fixing block. A card slot is opened on the surface of the fixing block. A steel column is placed on the surface of the fixing block. A second connection disk is fixedly installed on the surface of the steel column. A clamping block is fixedly installed on the surface of the steel column. A screw hole is opened on the surface of the first connection disk. A first bolt is threadedly connected between the second connection disk and the screw hole. A rivet is fixedly installed at the bottom end of the bottom plate body. A conical nail head is fixedly installed at the top end of the rivet.

[0005] Preferably, a groove is opened on the surface of the second connection disk, and the diameter of the groove is larger than the diameter of the first bolt. Here, when the first bolt fixes the first connection disk and the second connection disk, the first bolt can be hidden in the groove on the surface of the second connection disk. In this way, not only can space be saved, but also the first bolt can be protected from rain corrosion, thereby increasing the service life of the first bolt.

[0006] Preferably, a barbed ring is fixedly installed on the surface of the rivet. Here, when the steel support bottom plate is installed, the rivet is first inserted into the soil. The conical ring head on the surface of the rivet can break the soil. When the rivet is completely inserted into the soil, the barbed ring can increase the contact area between the rivet and the soil, making the bottom plate body more stable during support.

[0007] Preferably, the clamping block is adapted to the clamping groove, and the shape of the clamping block is cross-shaped. Here, the cross-shaped clamping block can not only fit the fixing block more closely, but also limit the fixing block, effectively preventing the steel column from being misaligned with the fixing block and improving the safety of the support bottom plate structure.

[0008] Preferably, the number of the first bolts is four groups, and the four groups of the first bolts are arranged in a circumferential array on the surface of the second connection plate. Here, the four groups of first bolts can better fix the second connection plate and the first connection plate stably. The first bolts are screwed in vertically and will not be deformed by extrusion, which is safer.

[0009] Preferably, a first collar is placed on the surfaces of the first connection plate and the second connection plate. A second collar is rotatably connected to the surface of the first collar, and a second bolt is threadedly connected between the first collar and the second collar. Here, when the first connection plate and the second connection plate are fixed, the first collar is placed on the surface of the first connection plate, and then the second collar is rotated so that the second collar fits the first connection plate. Then, the second bolt is used to fix the first collar and the second collar. In this way, it can effectively protect the internal parts from being damaged by impact and avoid rainwater corrosion of the internal bolts.

[0010] Preferably, the thickness of the inner wall of the first collar is equal to the sum of the thicknesses of the first connection plate and the second connection plate. Here, the first collar and the second collar fit the first connection plate and the second connection piece more closely, making the airtightness of the collar better and more waterproof.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. In the present utility model, by providing a bottom plate body, fixing blocks, a first connection plate, card slots, steel columns, a second connection plate, clamping blocks, first bolts, rivets, conical nail heads, and screw hole structures, the cross-shaped clamping blocks can not only fit the fixing blocks more closely but also limit the fixing blocks, effectively preventing the misalignment of the steel columns and the fixing blocks, improving the safety of the support bottom plate structure. The four groups of first bolts can better fix the second connection plate and the first connection plate stably. The first bolts are vertically screwed in, will not be deformed by extrusion, and are safer. Using four bolts for connection can also facilitate the disassembly and assembly of the steel support bottom plate. By providing groove and barbed ring structures, when the first bolts fix the first connection plate and the second connection plate, the first bolts can be hidden in the grooves on the surface of the second connection plate, which can not only save space but also protect the first bolts from rainwater corrosion, thus increasing the service life of the first bolts. The barbed ring can increase the contact area between the rivets and the soil, making the bottom plate body more stable during support.

[0013] 2. In the present utility model, by providing a first bushing, a second bushing, and second bolt structures, when the first connection plate and the second connection plate are fixed, place the first bushing on the surface of the first connection plate, then rotate the second bushing so that the second bushing fits the first connection plate, and then use the second bolts to fix the first bushing and the second bushing. The first bushing and the second bushing fit the first connection plate and the second connection piece more closely, making the airtightness of the bushing better and more waterproof. This can effectively protect the internal parts from being damaged by impact and also avoid rainwater corrosion of the internal bolts. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Embodiment 1

[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: a steel support bottom plate that can be quickly disassembled and assembled, including a bottom plate body 1. A fixing block 2 is fixedly installed on the surface of the bottom plate body 1. A first connection plate 3 is fixedly installed on the surface of the fixing block 2. A card slot 4 is opened on the surface of the fixing block 2. A steel column 5 is placed on the surface of the fixing block 2. A second connection plate 6 is fixedly installed on the surface of the steel column 5. A clamping block 7 is fixedly installed on the surface of the steel column 5. A screw hole 9 is opened on the surface of the first connection plate 3. A first bolt 10 is threadedly connected between the second connection plate 6 and the screw hole 9. A rivet 14 is fixedly installed at the bottom end of the bottom plate body 1. A conical nail head 15 is fixedly installed at the top end of the rivet 14. A groove 8 is opened on the surface of the second connection plate 6. The diameter of the groove 8 is larger than the diameter of the first bolt 10. When the first bolt 10 fixes the first connection plate 3 and the second connection plate 6, the first bolt 10 can be hidden in the groove 8 on the surface of the second connection plate 6. This can not only save space but also protect the first bolt 10 from rainwater corrosion, thereby increasing the service life of the first bolt 10. A barbed ring 16 is fixedly installed on the surface of the rivet 14. When installing the steel support bottom plate, first, the rivet 14 is inserted into the soil. The conical ring head on the surface of the rivet 14 can break open the soil. When the rivet 14 is completely inserted into the soil, the barbed ring 16 can increase the contact area between the rivet 14 and the soil, making the bottom plate body 1 more stable during support. The clamping block 7 is adapted to the card slot 4. The shape of the clamping block 7 is cross-shaped. The cross-shaped clamping block 7 can not only fit the fixing block 2 more closely but also limit the fixing block 2, effectively preventing the steel column 5 from being misaligned with the fixing block 2 and improving the safety of the support bottom plate structure. The number of the first bolts 10 is four groups. The four groups of first bolts 10 are arranged in a circular array on the surface of the second connection plate 6. The four groups of first bolts 10 can better fix the second connection plate 6 and the first connection plate 3 stably. The first bolts 10 are vertically screwed in and will not be deformed by extrusion, which is safer.

[0024] Embodiment 2

[0025] Please refer to Figure 1, a first clamping sleeve 11 is placed on the surfaces of the first connecting plate 3 and the second connecting plate 6. A second clamping sleeve 12 is rotatably connected to the surface of the first clamping sleeve 11. A second bolt 13 is threadedly connected between the first clamping sleeve 11 and the second clamping sleeve 12. When the first connecting plate 3 and the second connecting plate 6 are fixed, the first clamping sleeve 11 is placed on the surface of the first connecting plate 3. Then, the second clamping sleeve 12 is rotated so that the second clamping sleeve 12 fits with the first connecting plate 3. Then, the second bolt 13 is used to fix the first clamping sleeve 11 and the second clamping sleeve 12. In this way, it can effectively protect the internal parts from being damaged by impact, and at the same time, it can also prevent rainwater from corroding the internal first bolt 10. The thickness of the inner wall of the first clamping sleeve 11 is equal to the sum of the thicknesses of the first connecting plate 3 and the second connecting plate 6. The first clamping sleeve 11 and the second clamping sleeve 12 fit more closely to the first connecting plate 3 and the second connecting plate, making the airtightness of the clamping sleeve better and more waterproof.

[0026] Working principle: When in use, first insert the bottom plate body 1 and the rivet 14 into the soil. The conical head on the surface of the rivet 14 can break the soil. When the rivet 14 is completely inserted into the soil, the barbed ring 16 can increase the contact area between the rivet 14 and the soil, making the bottom plate body 1 more stable during support. Then, the clamping block 7 on the surface of the steel column 5 is slidably connected with the card slot 4 on the surface of the fixed block 2. When the two fit together, the first bolt 10 is used to fix the first connecting plate 3 and the first connecting plate 3. The four first bolts 10 can better fix the second connecting plate 6 and the first connecting plate 3 stably. The first bolts 10 are vertically screwed in and will not be deformed by extrusion, which is safer. When the first connecting plate 3 and the second connecting plate 6 are fixed, the first clamping sleeve 11 is placed on the surface of the first connecting plate 3. Then, the second clamping sleeve 12 is rotated so that the second clamping sleeve 12 fits with the first connecting plate 3. Then, the second bolt 13 is used to fix the first clamping sleeve 11 and the second clamping sleeve 12. The first clamping sleeve 11 and the second clamping sleeve 12 fit more closely to the first connecting plate 3 and the second connecting plate, making the airtightness of the clamping sleeve better and more waterproof. In this way, it can effectively protect the internal parts from being damaged by impact, and at the same time, it can also prevent rainwater from corroding the internal first bolt 10.
