Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, specifically a scaffolding base. Background Technology

[0002] In a typical scaffolding erection method, the vertical members of the scaffolding are supported by a scaffolding base. The scaffolding base includes a base plate and uprights fixed to the base plate, with the bottom ends of the vertical members fitting over the outside of the uprights. However, this scaffolding base has poor radial stability of the vertical members, making it prone to overturning when the ground is sloping or the scaffolding is erected to a large height, which is detrimental to safe construction.

[0003] Chinese patent CN205502561U discloses a scaffolding base that decomposes the force exerted by the vertical rods of the scaffolding on the sleeve into lateral and longitudinal components. The sleeve and support members transmit these lateral and longitudinal components to the base plate. The lateral component is ultimately balanced by the friction between the base plate and the ground, and the longitudinal component is ultimately balanced by the longitudinal support force exerted by the ground on the base plate. In addition, while the support members are subjected to the lateral component force of the sleeve, the support members also generate a reverse lateral support force on the sleeve, which improves the sleeve's ability to resist the lateral component force of the scaffolding, thereby improving the anti-overturning ability of the scaffolding base.

[0004] Conventional scaffolding requires four or more bases. The aforementioned scaffolding bases have sleeves, ribs, and supports on the top of the base plate, which makes it difficult to stack multiple bases together when carrying them. This makes them inconvenient to carry and takes up a lot of space. Utility Model Content

[0005] The purpose of this utility model is to provide a scaffolding base to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scaffold base, comprising a base plate, a frustum sleeve fixedly installed on the top of the base plate, a trapezoidal rib fixedly installed on the outer wall of the frustum sleeve, both the frustum sleeve and the trapezoidal rib being hollow steel components, and the interiors of the frustum sleeve and the trapezoidal rib being interconnected, a through groove being provided at the bottom of the base plate, the through groove being aligned with the frustum sleeve and the trapezoidal rib, a guide cylinder fixedly installed on the top of the frustum sleeve, the guide cylinder being interconnected with the interior of the frustum sleeve, a fixed seat fixedly installed on the top of the base plate, a diagonal brace fixedly installed on the inner side of the fixed seat by fixing bolts, a connecting collar fixedly installed at the top of the diagonal brace, and the connecting collar being movably sleeved on the guide cylinder.

[0007] Furthermore, a fastening bolt is threaded onto the connecting collar, and a through hole is provided on the outer wall of the guide cylinder, through which the fastening bolt passes.

[0008] Furthermore, anti-tilt plates are fixedly installed around the base plate. One section of the anti-tilt plate connected to the base plate is parallel to the base plate, while the other section of the anti-tilt plate away from the base plate is tilted upwards.

[0009] Furthermore, the anti-tilt plate is installed on the base plate by welding, and there are four sets of anti-tilt plates, which are respectively fixedly installed on the four sides of the base plate.

[0010] Furthermore, the bottom of the upward-curving section of the anti-tilt plate is provided with anti-slip texture.

[0011] Furthermore, the top of the base plate is provided with five through holes, which are located at the four corners of the top of the base plate and the center of the left end of the base plate, respectively.

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

[0013] 1. Because both the frustum sleeve and the trapezoidal rib are larger at the top and smaller at the bottom, and both the frustum sleeve and the trapezoidal rib are hollow steel components, when multiple bases are stacked together, it can be ensured that the lower frustum sleeve and trapezoidal rib pass through the through slot and are inserted into the upper frustum sleeve and trapezoidal rib, so that multiple scaffold bases can be stacked together, making it easier to carry the scaffold bases.

[0014] 2. Because the diagonal brace is connected to the fixed seat by fixing bolts, the diagonal brace and connecting collar can be removed when carrying it. This can provide lateral support for the guide tube without hindering the stacking of multiple bases. The guide tube is set to guide the scaffold support rod, making it convenient for workers to insert the scaffold support rod into the truncated cone sleeve. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a scaffold base, including a base plate 1, a frustum sleeve 2 fixedly installed on the top of the base plate 1, a trapezoidal rib 3 fixedly installed on the outer wall of the frustum sleeve 2, both the frustum sleeve 2 and the trapezoidal rib 3 being hollow steel components, and the interiors of the frustum sleeve 2 and the trapezoidal rib 3 being interconnected, a through groove 4 being opened at the bottom of the base plate 1, the through groove 4 being aligned with the frustum sleeve 2 and the trapezoidal rib 3, a guide cylinder 7 fixedly installed on the top of the frustum sleeve 2, the guide cylinder 7 being interconnected with the interior of the frustum sleeve 2, a fixing seat 8 fixedly installed on the top of the base plate 1, a diagonal brace 10 fixedly installed on the inner side of the fixing seat 8 by fixing bolts 9, a connecting collar 11 fixedly installed on the top of the diagonal brace 10, the connecting collar 11 being movably sleeved on the guide cylinder 7. Because both the frustum sleeve 2 and the trapezoidal rib 3 are larger at the top and smaller at the bottom, and both the frustum sleeve 2 and the trapezoidal rib 3 are hollow steel components, when multiple bases are stacked together, it can be ensured that the lower frustum sleeve 2 and trapezoidal rib 3 pass through the through slot 4 and are inserted into the upper frustum sleeve 2 and trapezoidal rib 3. This allows multiple scaffold bases to be stacked together, making it easier to carry the scaffold bases. Because the diagonal brace 10 is connected to the fixed seat 8 by the fixing bolt 9, the diagonal brace 10 and the connecting collar 11 can be removed when carrying. This can achieve lateral support for the guide cylinder 7 without hindering the stacking of multiple bases. The guide cylinder 7 is set to guide the scaffold support rods, making it convenient for workers to insert the scaffold support rods into the frustum sleeve 2.

[0023] The connecting collar 11 is threaded with a fastening bolt 12. The outer wall of the guide cylinder 7 is provided with a through hole. The fastening bolt 12 passes through the through hole. After the scaffold support rod is inserted into the frustum sleeve 2, the fastening bolt 12 can be rotated so that the end of the fastening bolt 12 presses tightly on the scaffold support rod, so that the scaffold support rod will not easily come out of the frustum sleeve 2.

[0024] Anti-tilt plates 5 are fixedly installed around the base plate 1. The section of the anti-tilt plate 5 connected to the base plate 1 is parallel to the base plate 1. The section of the anti-tilt plate 5 away from the base plate 1 is tilted upward. When the scaffold base tilts, the anti-tilt plate 5 will contact the ground before the side of the base plate 1, thereby providing lateral support to the base plate 1 and preventing the base plate 1 from tilting further.

[0025] The anti-tilt plate 5 is installed on the base plate 1 by welding. There are four sets of anti-tilt plates 5, which are fixedly installed on the four sides of the base plate 1 respectively, so that no matter which direction the base plate 1 tilts, there is a corresponding anti-tilt plate 5 to provide lateral support to the base plate 1.

[0026] The bottom of the upward-curving section of the anti-tilt plate 5 is provided with anti-slip texture. When the base plate 1 is tilted, the contact area between the base plate 1 and the ground is reduced. At this time, the anti-tilt plate 5 provides lateral support to the base plate 1. The anti-slip texture on the anti-tilt plate 5 can effectively increase the friction between the anti-tilt plate 5 and the ground, thereby preventing the base plate 1 from sliding.

[0027] The top of the base plate 1 has five through holes 6, which are located at the four corners of the top of the base plate 1 and the center of the left end of the base plate 1, respectively. After multiple scaffold bases are stacked together, the pins can be passed through the through holes 6 on the base plate 1 to prevent the stacked scaffold bases from separating when carrying them.

[0028] Working principle: When in use, multiple scaffolding bases can be stacked together for simultaneous transport. When supporting the scaffolding, the scaffolding support rod is inserted into the guide tube 7, and then the guide tube 7 is inserted into the frustum sleeve 2. The connecting collar 11 is placed on the guide tube 7, and the bottom end of the diagonal brace 10 is fixedly connected to the fixed seat 8 using the fixing bolt 9. The fastening bolt 12 is rotated so that the end of the fastening bolt 12 is pressed tightly against the scaffolding support rod, thus supporting the scaffolding.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
