AI Technical Summary
Traditional disc-lock scaffolding has a fixed horizontal pipe length, which is difficult to adjust flexibly. This results in the lateral force of the formwork not being effectively transferred to the steel pipe scaffolding when the building structure protrudes to the side, thus failing to meet construction requirements.
An adjustable base, adjustable support, horizontal tube, first fastener and diagonal brace assembly are adopted. By cutting the horizontal tube to an appropriate length and connecting it with the upright, a stable support system is formed. The stability and strength are enhanced by the combination of adjustable support and diagonal brace assembly. The lateral force of the template is transmitted by the connecting rod and the abutment seat.
It effectively supports the formwork on the protruding side of the building structure, ensuring that lateral forces are transferred to the steel pipe support, improving the stability and strength of the support, and meeting construction requirements.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe support technology, and in particular to a steel pipe support for the protruding side wall of an underground frame structure. Background Technology
[0002] Underground frame structure (a frame structure with no backfilling of side walls and only single-sided formwork allowed) is a widely used structural form in underground construction. It uses linear components such as beams and columns to form a load-bearing skeleton and features flexible layout and high space utilization. This structure is suitable for scenarios such as subway stations, underground parking garages, and civil defense projects. Through reasonable column grid layout and component design, it can meet functional requirements and ensure structural safety.
[0003] Currently, some underground frame structures adopt protruding side walls (the inner wall of the foundation pit protrudes inward by a certain distance) in the design stage. Due to the protruding characteristics of the structure, when supporting the formwork, it is difficult to flexibly adjust the position and length of the horizontal pipes because the pipe length of the traditional disc-lock scaffold is fixed. As a result, the horizontal pipes cannot be abutted against the formwork to transfer the lateral force of the formwork to the frame, which cannot meet the construction requirements. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a steel pipe support for the protruding side wall of an underground frame structure. It solves the problem that conventional disc-lock supports, which use standardized length horizontal pipes, cannot effectively transmit the lateral force of the formwork to the steel pipe support when encountering the protruding side of the building structure.
[0005] According to an embodiment of this utility model, an underground frame structure protruding sidewall steel pipe support includes an adjustable base, adjustable supports, a horizontal pipe, first fasteners, and diagonal bracing components. The top of the adjustable base is detachably connected to multiple uprights. Each upright has several discs on its outer wall, and several connecting holes are opened on the discs. There are several adjustable supports, which are detachably set on the top of the topmost upright. There are several first fasteners, one end of each first fastener is engaged with the upright, and the other end of each first fastener is engaged with the horizontal pipe. There are several diagonal bracing components, which are detachably set on the discs between two uprights.
[0006] Compared with the existing technology, this utility model has the following beneficial effects: By adopting the existing disc-lock scaffold, the disc-lock horizontal bar perpendicular to the side wall direction is eliminated and replaced with a horizontal tube cut to the required size according to the site conditions. The two ends of the horizontal tube can abut against the templates on both sides and cooperate with adjustable supports to support the side wall templates and top formwork. The horizontal tube is connected to the uprights through the first fastener to form a stable support system. The diagonal bracing component further enhances the stability and structural strength of the steel pipe scaffold. Under the premise of ensuring that the steel pipe scaffold is stable and has sufficient strength, it avoids the problem that the templates on the protruding side of the building structure are not easy to support and cannot effectively transfer the lateral force to the steel pipe scaffold.
[0007] Furthermore, it also includes a connecting rod, with a second fastener at both ends. The second fastener at one end of the connecting rod engages with one of the horizontal pipes, and the second fastener at the other end of the connecting rod engages with another horizontal pipe.
[0008] Furthermore, each second fastener includes: a first connector connected to each connecting rod, a second connector hinged to each first connector, the free end of the first connector and the free end of the second connector being detachably connected, and an arc-shaped groove for the horizontal pipe to be inserted on the opposite sides of the first connector and the second connector.
[0009] Furthermore, a pin is provided on the inner wall of the first connector at one end of each connecting rod.
[0010] Furthermore, each pin is threadedly connected to the first connector.
[0011] Furthermore, the connecting rod is a telescopic rod.
[0012] Furthermore, each diagonal brace assembly includes a diagonal rod, with connecting blocks at both ends of each diagonal rod. The connecting blocks are concave, and each connecting block is detachably connected to the disc.
[0013] Furthermore, each horizontal tube has a detachable abutment at its end. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0019] like Figures 1 to 2 As shown in the figure, this utility model embodiment proposes a steel pipe support for the protruding side wall of an underground frame structure, including an adjustable base 1, an adjustable support 4, a horizontal pipe 5, a first fastener 6, and a diagonal brace assembly. The top of the adjustable base 1 is detachably connected to multiple uprights 2. Each upright 2 has several discs 3 on its outer wall, and several connecting holes are opened on the discs 3. There are several adjustable supports 4, which are detachably set on the top of the topmost upright 2. There are several first fasteners 6, one end of each first fastener 6 is attached to the upright 2, and the other end of each first fastener 6 is attached to the horizontal pipe 5. There are several diagonal brace assemblies, which are detachably set on the discs 3 between two uprights 2. The adjustable base 1, adjustable support 4, and upright 2 are connected detachably via threaded sleeves. Multiple uprights 2 are connected end-to-end in the vertical direction on the same adjustable base 1. All three components can be selected from existing disc-lock scaffolding systems. The structure of the first fastener 6 is a commonly used fastener structure in scaffolding, and its specific structure will not be described in detail. In this embodiment, the steel pipe support is used in a foundation pit. When assembling the steel pipe support, several adjustable bases 1 are first set at predetermined positions, and uprights 2 are set on the adjustable bases 1. Horizontal pipes 5 are cut according to the size of the foundation pit. When encountering the protruding side of the building structure, horizontal pipes 5 of corresponding length are cut. Then, the horizontal pipes 5 are horizontally erected on multiple uprights 2 using multiple first fasteners 6. 2 is a single layer, with a horizontal pipe 5 installed on each layer of uprights 2. Several uprights 2, horizontal pipes 5, and adjustable bases 1 at the bottom form a steel pipe support. Both ends of the horizontal pipes 5 abut against the templates set at both ends of the foundation pit, thereby supporting the templates at both ends of the foundation pit. This device replaces the horizontal bar perpendicular to the side wall with a horizontal pipe 5 and an adjustable support 4 to support the side wall templates and top formwork. The horizontal pipes 5 and the uprights 2 are connected by fasteners to form a stable support system. The horizontal pipes 5 can be cut to appropriate lengths as needed to effectively solve the support problem of the protruding part of the side wall structure. At the same time, the horizontal pipes 5 support the templates at both ends of the foundation pit, improving the support force requirements of the templates.
[0020] like Figures 1 to 3As shown, it further includes a connecting rod 7, with a second fastener 8 at both ends. The second fastener 8 at one end of the connecting rod 7 engages with one of the horizontal pipes 5, and the second fastener 8 at the other end of the connecting rod 7 engages with the other horizontal pipe 5. The connecting rod 7 is installed between two adjacent horizontal pipes 5 via the second fastener 8, connecting the two horizontal pipes 5 together, increasing the connection force between the two horizontal pipes 5, forming a more stable frame structure, and improving the support strength for the formwork.
[0021] like Figure 3 As shown, each second fastener 8 further includes: a first connecting member 801 connected to each connecting rod 7, a second connecting member 802 hinged to each first connecting member 801, the free ends of the first connecting member 801 and the second connecting member 802 being detachably connected, and arc-shaped grooves for the horizontal tube 5 to be inserted on opposite sides of the first connecting member 801 and the second connecting member 802. When connecting the connecting rod 7 to the two horizontal tubes 5, the first connecting member 801 and the second connecting member 802 at one end of the connecting rod 7 are first held onto the horizontal tube 5, and the other horizontal tube 5 is inserted into the groove of the first connecting member 801. Then, the second connecting member 802 is held onto the first connecting member 801. In this embodiment, the free ends of the first connecting member 801 and the second connecting member 802 are detachably connected by bolts.
[0022] like Figure 3 As shown, furthermore, a pin 803 is provided on the inner wall of the first connecting member 801 at one end of each connecting rod 7. Specifically, the pin 803 is located in the groove of the first connecting member 801. In order to further limit the possible displacement of the horizontal rod in the horizontal direction, a pin 803 is provided on the first connecting member 801, and a socket for inserting the pin 803 is provided on the horizontal tube 5. The socket can be pre-drilled or drilled when needed. By inserting the pin 803 on the first connecting member 801 into the socket, the displacement of the horizontal tube 5 in the horizontal direction is limited. By setting connecting rods 7 between the horizontal rods on the multi-layered uprights 2, they mutually limit each other, forming a stable steel pipe support.
[0023] Furthermore, each pin 803 is threadedly connected to the first connector 801. This threaded detachment allows the pin 803 to be easily removed when it is not needed or inconvenient to use under certain operating conditions.
[0024] Furthermore, the connecting rod 7 is a telescopic rod. The telescopic method of the connecting rod 7 can be selected from existing technologies, such as spiral or pipe joint type. The telescopic nature of the connecting rod 7 facilitates adaptation to horizontal pipes 5 with different spacings and also facilitates the installation of the connecting rod 7 between two horizontal pipes 5.
[0025] like Figures 1 to 2As shown, each diagonal brace assembly further includes: a diagonal rod 9, with connecting blocks 10 at both ends of each diagonal rod 9. The connecting blocks 10 are concave, and each connecting block 10 is detachably connected to the disc 3. When installing the diagonal rod 9, the connecting blocks 10 at both ends of the diagonal rod 9 are respectively inserted into the disc 3. In this embodiment, the disc 3 is a disc buckle frame disc 3 with several pre-drilled connecting holes. The disc 3 is inserted into the concave groove on the concave connecting block 10, and then the connecting block 10 and the disc 3 are locked and fixed by bolts and nuts. By setting the diagonal rod 9, the strength between the uprights 2 is improved, thereby improving the strength and stability of the entire steel pipe frame.
[0026] like Figures 1 to 2 As shown, furthermore, each horizontal pipe 5 is detachably provided with an abutment seat 11 at its end. Specifically, the abutment seat 11 can be a T-shaped structure, with the thinner end of the abutment seat 11 engaging inside the pipe body of the horizontal pipe 5. The connection between the abutment seat 11 and the horizontal pipe 5 can also be a threaded connection. By screwing the abutment seat 11 into or out of the horizontal pipe 5, the abutment seat 11 can be finely adjusted. The abutment seat 11 is provided with a handle to facilitate screwing the abutment seat 11 into or out, compensating for and filling the gap between the horizontal pipe 5 and the template after installation, so that the end of the abutment seat 11 abuts against the template, thereby transmitting the lateral force of the template to the steel pipe support.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
