Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, and more specifically, to a support and anti-slip device for a cantilevered concrete structure base. Background Technology

[0002] In the construction technology of concrete structures in building buildings, formwork scaffolding support technology is relatively mature, mainly including: steel pipe coupler scaffolding support systems, ring-lock socket scaffolding support systems, and disc-lock socket scaffolding support systems. However, due to technical limitations, ring-lock socket scaffolding support systems are generally not used for support structures exceeding 8 meters in height; steel pipe coupler scaffolding support systems and disc-lock socket scaffolding support systems are more commonly used. Among the aforementioned scaffolding support systems, the scaffolding plays a significant role in supporting gravity in the vertical direction, but its ability to resist lateral horizontal forces is relatively weak. Especially in large cantilevered concrete structures with an inclined angle, the horizontal lateral forces generated by the inclination angle may cause slippage or structural instability of the support structure.

[0003] In summary, how to solve the problem of frame support where the load-bearing capacity of the support frame cannot meet the support requirements and the standard layout is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a support and anti-slip device for the base of a cantilevered concrete structure, which can solve the problem of the support frame not being able to meet the support requirements and not being able to meet the standard layout of the frame support.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cantilevered concrete structure base support and anti-slip device, comprising:

[0007] Anti-slip base, which is installed in the anti-slip groove on the ground;

[0008] The first support member is vertically mounted on the anti-slip base;

[0009] The second support member is used to support the bottom of the cantilevered concrete structure, and the second support member is located on top of the first support member;

[0010] The reinforcing component is disposed between the second support member and the first support member, and between the first support member and the anti-slip base.

[0011] In one embodiment, the second support member is inclinedly disposed on top of the first support member.

[0012] In one embodiment, the second support member is welded to the top of the first support member, the bottom of the first support member is welded to the anti-slip base, the reinforcing member is welded between the second support member and the first support member, and the reinforcing member is welded between the first support member and the anti-slip base.

[0013] In one embodiment, the first support member includes two vertically arranged C-shaped channel steels and at least two first connectors, each of which is vertically welded between the two C-shaped channel steels.

[0014] In one embodiment, the second support member includes two parallel I-beams disposed on top of the first support member and at least two second connectors, each of the second connectors being vertically welded between the two I-beams.

[0015] In one embodiment, each of the second connectors has a mounting groove on its top, the mounting groove being used to engage the support steel pipe of the cantilevered concrete structure.

[0016] In one embodiment, the second connector is provided with at least two mounting grooves at equal intervals along its length.

[0017] In one embodiment, the reinforcement includes two first steel pipes and two second steel pipes arranged parallel between the second support and the first support. The second steel pipes are arranged parallel between the first support and the anti-slip base. The first steel pipes and the second steel pipes are either in a straight line or staggered.

[0018] In one embodiment, at least one reinforcing connector is vertically provided between the two first steel pipe fittings and between the two second steel pipe fittings.

[0019] In one embodiment, the anti-slip base includes two parallel C-shaped channel steels and a connecting portion for connecting the two C-shaped channel steels, wherein the C-shaped channel steels and the connecting portion are welded and fixed.

[0020] When using the cantilevered concrete structure base support and anti-slip device provided by this utility model, firstly, multiple anti-slip grooves can be set on the ground at the required locations as needed. Then, the anti-slip base is hoisted into the anti-slip groove to fix it in place and prevent slippage. Next, the first support member is hoisted and positioned vertically on the anti-slip base, and the first support member and the anti-slip base can be welded together. Subsequently, depending on the structure and location of the cantilevered concrete structure, the second support member is inclined or vertically positioned on top of the first support member to ensure effective support of the bottom of the cantilevered concrete structure, and the second support member and the first support member can be welded together. Finally, reinforcement members (such as by welding) are installed between the second and first support members, and between the first support member and the anti-slip base, to strengthen the connection between the second and first support members and the connection between the first support member and the anti-slip base.

[0021] For cantilevered concrete structures with an inclined angle, the tilt generates horizontal lateral forces, potentially causing slippage in the support frame. In this device, a second support member is inclinedly positioned on top of the first support member, ensuring effective support of the bottom of the cantilevered concrete structure. Furthermore, the first support member is vertically mounted on an anti-slip base, which is fixed within an anti-slip groove in the ground. These components effectively improve the overall stability of the support frame, enhance its vertical load-bearing capacity and lateral resistance, and significantly improve its horizontal anti-slip capability, preventing horizontal slippage during concrete pouring and thus avoiding structural instability and collapse. In short, this device solves the problem of insufficient load-bearing capacity in the support frame to meet support requirements.

[0022] In summary, the cantilevered concrete structure base support and anti-slip device provided by this utility model can solve the problem of frame support where the load-bearing capacity of the support frame cannot meet the support requirements and cannot meet the standard layout.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] The core of this utility model is to provide a support and anti-slip device for the base of a cantilevered concrete structure, which can solve the problem of the support frame not being able to meet the support requirements and not being able to meet the standard layout of the frame support.

[0040] Please refer to Figures 1 to 4 This specific embodiment provides a cantilevered concrete structure base support and anti-slip device, including:

[0041] Anti-slip base 3, which is located in the anti-slip groove 6 on the ground;

[0042] The first support member 1 is vertically mounted on the anti-slip base 3;

[0043] The second support member 2 is used to support the bottom of the cantilevered concrete structure 5, and the second support member 2 is located on top of the first support member 1;

[0044] The reinforcement component 4 is located between the second support 2 and the first support 1, and between the first support 1 and the anti-slip base 3.

[0045] In practical applications, the shape, structure, size, material, and position of the anti-slip base 3, the first support 1, the second support 2, and the reinforcement 4 can be determined according to the actual situation and needs.

[0046] When using the cantilever concrete structure base support and anti-slip device provided by this utility model, firstly, multiple anti-slip grooves 6 can be set on the ground at the required locations as needed. Then, the anti-slip base 3 is hoisted into the anti-slip groove 6 to fix it in place and prevent it from sliding. Next, the first support member 1 is hoisted so that it is vertically positioned on the anti-slip base 3, and the first support member 1 and the anti-slip base 3 can be welded together. Subsequently, depending on the structure and position of the cantilever concrete structure 5, the second support member 2 is inclined or vertically positioned on top of the first support member 1 to ensure that the second support member 2 effectively supports the bottom of the cantilever concrete structure 5, and the second support member 2 and the first support member 1 can be welded together. Finally, reinforcement members 4 are installed (e.g., welded) between the second support member 2 and the first support member 1, and between the first support member 1 and the anti-slip base 3, to strengthen the connection between the second support member 2 and the first support member 1, and to strengthen the connection between the first support member 1 and the anti-slip base 3.

[0047] In this device, the cantilevered concrete structure 5, with its tilted angle, generates horizontal lateral forces, potentially causing slippage in the support frame. The second support member 2 is tilted and positioned above the first support member 1, ensuring effective support of the bottom of the cantilevered concrete structure 5. Furthermore, the first support member 1 is vertically mounted on the anti-slip base 3, which is fixedly installed within the anti-slip groove 6 on the ground. These components effectively improve the overall stability of the support frame, enhance its vertical load-bearing capacity and lateral resistance, and significantly improve its horizontal anti-slip capability, preventing horizontal slippage during the pouring of concrete and thus avoiding instability and collapse of the cantilevered concrete structure 5. In other words, this device solves the problem of insufficient load-bearing capacity of the support frame to meet support requirements.

[0048] In summary, the cantilevered concrete structure base support and anti-slip device provided by this utility model can solve the problem of frame support where the load-bearing capacity of the support frame cannot meet the support requirements and cannot meet the standard layout.

[0049] In one embodiment, the second support member 2 is inclinedly disposed on top of the first support member 1. During use, the design can be tailored to the inclination angle of the cantilevered concrete structure 5, so that the second support member 2 is inclinedly disposed on top of the first support member 1, ensuring that the second support member 2 effectively supports the bottom of the cantilevered concrete structure 5 and preventing horizontal slippage during concrete pouring that could cause the cantilevered concrete structure 5 to become unstable and collapse.

[0050] In one embodiment, the second support member 2 is welded to the top of the first support member 1, the bottom of the first support member 1 is welded to the anti-slip base 3, and the reinforcing member 4 is welded between the second support member 2 and the first support member 1, and between the first support member 1 and the anti-slip base 3. The use of welding to connect the components helps improve the connection strength between them and eliminates the need for additional connectors (such as bolts or rivets), thus simplifying the structural design and reducing material costs.

[0051] In one embodiment, the first support member 1 includes two vertically arranged C-shaped channel steels 11 and at least two first connectors 12, each of which is vertically welded between the two C-shaped channel steels 11.

[0052] It should be noted that the C-shaped channel steel 11 of the first support member 1 can be made of 300-type C-shaped channel steel 11. The 300-type C-shaped channel steel 11 is a cold-formed steel with specific cross-sectional dimensions, whose core parameters reflect the balance between structural design and performance. According to national standards, the dimensions of this type of channel steel are 300mm × 100mm × 10.5mm, where 300mm is the width (web height), 100mm is the flange width, and 10.5mm is the thickness, with a weight of 15.3kg / m. This dimensional design aims to optimize bending strength and load-bearing capacity, making it suitable for various load-bearing scenarios.

[0053] In one embodiment, the second support member 2 includes two parallel I-beams 21 disposed on top of the first support member 1 and at least two second connectors 22. Each second connector 22 is vertically welded between two I-beams 21, so that the second support member 2 forms a rectangular frame, thereby effectively supporting the bottom of the cantilevered concrete structure 5. The second connector 22 and the first connector 12 located at the connection between the second support member 2 and the first support member 1 can overlap.

[0054] It should be noted that the I-beam 21 can be configured as a 150-type I-beam 21, where the specifications are 150mm × 7mm × 10mm. 150mm represents the web height (section height) and flange width (flange width), 7mm represents the web thickness (web thickness), and 10mm represents the average flange thickness (average flange thickness). The 150-type I-beam 21 has an "I"-shaped cross-section, composed of upper and lower flanges and a middle web. The flanges gradually thin from the root to the edge, forming a certain angle. This design allows it to effectively distribute loads under stress.

[0055] In one embodiment, such as Figure 5 and Figure 6 As shown, each of the second connectors 22 has a mounting groove 23 on its top, which is used to engage the supporting steel pipe of the cantilevered concrete structure 5. The mounting groove 23 can be configured as an arc-shaped groove, the shape and size of which match the shape and size of the supporting steel pipe, so that the mounting groove 23 can effectively engage the supporting steel pipe of the cantilevered concrete structure 5.

[0056] In one embodiment, the second connector 22 is provided with at least two mounting grooves 23 at equal intervals along its length, which facilitates the manufacturing of the second connector 22 and improves the supporting and fixing effect of the second connector 22 on the supporting steel pipe.

[0057] In one embodiment, such as Figure 1As shown, the reinforcement component 4 includes two first steel pipe components 41 and two second steel pipe components 42 arranged in parallel between the second support component 2 and the first support component 1. The second steel pipe components 42 are arranged in parallel between the first support component 1 and the anti-slip base 3. The first steel pipe components 41 and the second steel pipe components 42 are arranged in a straight line or staggered.

[0058] It should be noted that, since the second support member 2 is inclinedly positioned on top of the first support member 1, the connection effect between the second support member 2, the first support member 1, and the anti-slip base 3 is improved by setting two parallel first steel pipe members 41 between the second support member 2 and the first support member 1, and two parallel second steel pipe members 42 between the first support member 1 and the anti-slip base 3. The first steel pipe members 41 and the second steel pipe members 42 are arranged in a straight line or staggered. When the first steel pipe members 41 and the second steel pipe members 42 are arranged in a straight line, the structural stability of the first steel pipe members 41 and the second steel pipe members 42 can be further improved.

[0059] In one embodiment, at least one reinforcing connector 43 is provided vertically between the two first steel pipe fittings 41 and between the two second steel pipe fittings 42, so as to make the connection between the first steel pipe fittings 41 and the second steel pipe fittings 42 more stable.

[0060] In one embodiment, the anti-slip base 3 includes two parallel C-shaped channel steels 11 and a connecting portion 31 for connecting the two C-shaped channel steels 11. The C-shaped channel steels 11 and the connecting portion 31 are welded and fixed to improve the structural stability of the anti-slip base 3. The connecting portion 31 and the first connecting member 12 may overlap or be staggered.

[0061] To further illustrate the usage of the cantilevered concrete structure base support and anti-slip device provided by this utility model, examples will be given below.

[0062] First, such as Figure 7 As shown, anti-slip grooves 6 are installed in the concrete structure of the ground according to the dimensions of the anti-slip base 3. Then, as... Figure 8 As shown, hoist the anti-slip base 3 into the anti-slip sliding groove 6. Then, as... Figure 9 As shown, the first support component 1 is hoisted and welded to the anti-slip base 3. Then, as... Figure 10 As shown, the second support member 2 is hoisted and then welded at an angle to the top of the first support member 1. Subsequently, as... Figure 11 As shown, the reinforcement component 4 is hoisted and welded between the second support component 2 and the first support component 1, and between the first support component 1 and the anti-slip base 3. Figure 12 It also shows the welding diagrams for each component.

[0063] This device solves the problem of scaffold support where the load-bearing capacity is insufficient to meet support requirements and the layout cannot meet specifications. Using this device, the vertical load-bearing capacity of the scaffold is enhanced because the first support member 1 is made of 300-type C-channel steel 11 and the second support member 2 is made of 150-type I-beam steel 21. Simultaneously, the anti-slip base 3 is also made of 150-type C-channel steel 11, welded to the first support member 1 to form a whole. The anti-slip base 3 is engaged in the anti-slip groove 6 (i.e., the concrete groove), significantly improving the horizontal anti-slip capacity and preventing horizontal slippage during concrete pouring that could cause the cantilevered concrete structure 5 to become unstable and collapse. For example, taking a 7800mm*600mm cantilevered concrete structure 5 as an example, if a disc-lock socket type support frame (i.e., cantilevered concrete structure 5) is used with a 250mm spacing between uprights, it cannot be installed (there are no 250mm uprights available, requiring customization). However, using this device reduces the number of disc-lock support uprights, avoiding increased costs due to customized materials.

[0064] It should be noted that the first support 1 and the second support 2, the first connector 12 and the second connector 22, the first steel pipe 41 and the second steel pipe 42 mentioned in this application are only distinguished by their different positions and do not have any order of precedence.

[0065] In addition, it should be noted that the orientation or positional relationship indicated by "vertical", "top and bottom" etc. in this application is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the purpose of simplifying the description and making it easier to understand, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

Similar or identical parts between embodiments can be referred to interchangeably.
