Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and specifically to a foundation pit construction support device. Background Technology

[0002] In the field of construction engineering, foundation pit construction is a crucial foundational step, and the support system, as the core equipment ensuring the safety of foundation pit construction, directly affects the stability of the foundation pit wall and the safety of construction personnel and equipment. With the continuous development of the construction industry, foundation pit engineering is characterized by increased depth, more complex geological conditions, and more diverse construction environments, placing higher demands on the adaptability, stability, and safety of support systems.

[0003] Currently, existing foundation pit construction support devices have many limitations. In terms of the base plate structure, traditional support devices mostly have a fixed length design for the base plate, which cannot be flexibly adjusted according to the actual width of the foundation pit. When facing foundation pits of different sizes, multiple specifications of base plates are required, which not only increases construction costs but also reduces construction efficiency, making it difficult to meet the needs of complex construction scenarios.

[0004] In terms of auxiliary support structures, existing support devices often use fixed connections with the base plate or baffle, and their length and support angle cannot be adjusted. Due to differences in the depth and inclination of different foundation pits, fixed auxiliary support components are difficult to form an effective triangular support system with the foundation pit wall, resulting in insufficient support strength and potential safety hazards such as foundation pit wall deformation and collapse.

[0005] Meanwhile, the design of stability enhancement components in existing support devices is not reasonable enough. Although some support devices are equipped with reinforcing structures, these structures are mostly integrated and fixed, and their length or angle cannot be adjusted according to the actual support stress. This results in limited reinforcement effect and weak overall load-bearing capacity of the support structure. When dealing with complex geological conditions or large lateral pressures, it is difficult to ensure the long-term stability of the support system.

[0006] Furthermore, the installation and dismantling of traditional support devices are cumbersome, and adjustments are inconvenient, requiring significant manpower and time, which severely impacts construction progress and further reduces the reliability of the support devices.

[0007] In summary, existing foundation pit construction support devices have significant shortcomings in terms of dimensional adaptability, support flexibility, structural stability, and ease of operation, failing to meet the requirements of efficient and safe construction in modern foundation pit engineering. Therefore, developing a foundation pit construction support device that is flexibly adjustable, stable, reliable, and easy to operate is of significant practical importance. Utility Model Content

[0008] Based on the above description, this utility model provides a foundation pit construction support device to solve the shortcomings of existing foundation pit support devices, which have simple structure, cumbersome operation, and cannot adjust their support width and the angle of the triangular support according to actual needs, resulting in poor safety and great inconvenience in use.

[0009] This utility model is achieved through the following technical solution:

[0010] A foundation pit construction support device includes a base plate, with baffles vertically arranged on both sides of the base plate, and the bottom end of the baffles being fixedly connected to the top surface of the base plate. Anchor nails are also provided at both ends of the base plate and inserted into the ground through the base plate. An auxiliary support component is also movably installed on the back of the baffle, and the bottom end of the auxiliary support component is slidably assembled with the top surface of the base plate to form a triangular support structure.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the base plate includes an adjustment plate A and an adjustment plate B, and an installation groove is provided at the center of the opposite side of the adjustment plate A and the adjustment plate B is fitted with a connecting plate. The surface of the connecting plate is also provided with a limiting groove. The inner side wall of the installation groove is provided with a snap-fit ​​part and is slidably installed inside the limiting groove. The limiting groove and the snap-fit ​​part are provided with pin holes of the same size and are locked and fixed by screws.

[0013] Furthermore, the auxiliary support includes a positioning groove on the surface of the baffle, a connecting seat is movably installed at the top of the positioning groove, a sliding groove is also provided on the top surface of the base plate, a fixed seat is movably installed on the sliding groove, and through holes are provided on the top surface of the fixed seat and the bottom surface of the sliding groove and fixed by inserting pins. A support plate is also provided on one side of the baffle, and the two ends of the support plate are movably hinged to the fixed seat and the connecting seat, respectively.

[0014] Furthermore, the support plate is composed of two interlocking rectangular metal plates, and the surfaces of the two rectangular metal plates are provided with positioning holes, and positioning pins are inserted into the positioning holes.

[0015] Furthermore, the support plate is provided with reinforcing ribs on both sides. The top of the reinforcing ribs is movably hinged to the support plate, and the other end of the reinforcing ribs is connected to a positioning plate and unfolds into an L-shape. The two positioning plates are respectively bolted to the top surface of the bottom plate and the surface of the baffle.

[0016] Furthermore, the reinforcing rib is composed of two rectangular metal parts that are movably connected, and each of the two metal parts has a positioning hole through it and is fixed by bolts.

[0017] Furthermore, the top edge of the connecting plate is also provided with marking scales, which extend to both sides from the center.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0019] This application improves upon existing foundation pit support devices by employing a structure where adjusting plate A and adjusting plate B are slidably assembled via a connecting plate. Combined with the engagement of the locking part and the limiting groove, and the fixing with screws, the length of the base plate can be flexibly adjusted according to the actual width of the foundation pit, eliminating the need for multiple specifications of base plates, significantly reducing construction costs and improving construction efficiency. Simultaneously, the markings on the top surface of the connecting plate accurately guide the adjustment process, ensuring assembly accuracy and solving the problem of poor adaptability of traditional fixed-length base plates. Furthermore, the auxiliary support components adopt a multi-dimensional adjustable design: the connecting seat can be flexibly positioned within the baffle positioning groove, and the fixed seat achieves position adjustment via a sliding groove. Combined with the movable hinges at both ends of the support plate, the angle of the triangular support structure can be precisely adapted to the inclination of the foundation pit wall. In addition, the support plate consists of two sleeved metal plates, and its length can be quickly adjusted via positioning pins, further enhancing the adaptability of the support structure to different foundation pit depths and effectively solving the problem of uneven stress distribution in traditional fixed support structures.

[0025] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0027] Combination Figure 1-4 As shown, a foundation pit construction support device includes:

[0028] The base plate 1 is the bottom structure of the entire support device. It is rectangular and its width can be adjusted according to actual needs by extending to both sides, thus eliminating the need to equip it with base plates of various specifications.

[0029] The baffle 2 is vertically installed on both sides of the top surface of the base plate 1. Its bottom is fixedly connected to the top surface of the base plate 1, and it forms a supporting effect by adhering to the inner wall of the pit.

[0030] An auxiliary support component is set between the baffle 2 and the base plate 1, and together with the baffle 2 and the base plate 1, they form a triangular support structure to improve the support strength of the baffle 2 and enhance its resistance to deformation.

[0031] Specifically, in this embodiment, the base plate 1 consists of an adjusting plate A11, an adjusting plate B12, and a connecting plate 3, for example... Figure 2 As shown, mounting grooves are provided on the opposite sides of adjusting plates A11 and B12. The two ends of the connecting plate 3 are inserted into the two mounting grooves simultaneously. The mounting grooves and the surfaces of the connecting plate 3 are grooved together using matching limiting grooves and snap-fit ​​parts. In order to prevent the connecting plate 3 from shrinking due to vibration in the mounting groove after subsequent adjustment, pin holes of the same size should also be provided on the snap-fit ​​part and the limiting groove. This allows the workers to quickly lock the base plate 1 with screws after the width is extended, so that the base plate 1 can be adaptively adjusted according to the actual width of the foundation pit. At the same time, marking scales can be set on the top surface or side wall of the connecting plate 3, extending from the center to both sides, so that the workers can control the adjustment distance.

[0032] In addition, the auxiliary support 3 includes a positioning groove 31 provided on the surface of the baffle 2. The top of the positioning groove 31 is provided with a connecting seat 32, and a support plate 35 is movably hinged to the connecting seat 32. A sliding groove 33 is provided on the top surface of the adjusting plate A11 and the adjusting plate B12. The other end of the connecting seat 32 is movably hinged to a fixed seat 34, and the fixed seat 34 is slidably assembled with the sliding groove 33. Therefore, the support plate 35 can flexibly adjust the support angle through the hinge structure.

[0033] Both the fixed base 34 and the connecting base 32 should be equipped with through holes, and the pins should be used to connect and fix them with the corresponding sliding grooves 33 or positioning grooves 31 through the through holes so that they can be locked after adjustment to ensure that the support plate 35 will not be deformed due to the huge squeezing force on both sides.

[0034] Furthermore, in actual use, when the angle of the connecting plate 3 is adjusted, its length should also be adjusted accordingly. Therefore, the connecting plate 3 should be composed of two interlocking rectangular metal plates. Positioning holes can be opened on the surface of the two interlocking rectangular metal plates, and pins can be used to quickly fix them after adjustment.

[0035] Based on the above structure, the connecting seat 32 and the baffle 2 should be integrated or bolted together. The fixing seat 34 can be separated from the slide 33 at any time. Therefore, during the recycling process, the support plate 35 can be folded so that it can rotate around the hinge point on the connecting seat 32 and be stored in the positioning groove 31 on the surface of the baffle 2, forming a horizontal plate for easy transportation. Moreover, this modular structure can be quickly unfolded by rotating its supporting components, greatly improving its ease of use.

[0036] To further enhance the stability of the auxiliary support 3 during the support process, especially when the auxiliary support 3 extends for a long distance, it is necessary to equip its lower half side wall with reinforcing ribs 36. Two reinforcing ribs 36 are provided and arranged on both sides of the support plate 35, with their top ends hinged to the end face of the support plate 35, thus extending towards the side wall of the baffle 2. At their ends, two positioning plates 37 are detachably installed with bolts. The two positioning plates 37 unfold into an L-shape and are simultaneously bolted to the side wall of the support plate 35 and the adjusting plate A11 (or adjusting plate B12), respectively. For example, see attached... Figure 3 and attached Figure 4 As shown in the image.

[0037] The reinforcing rib 36 should also be designed using the telescopic structure of the support plate 35, using two metal plates to be sleeved together, thereby realizing the function of sliding adjustment of its length, ensuring that the structure can be adjusted according to the usage requirements, and after adjustment, it will provide support for the entire support structure, thereby improving the overall support strength.

[0038] Furthermore, based on the aforementioned reinforcing rib 36, holes can be pre-drilled in the side wall of the reinforcing rib 36, and then longitudinally inserted into the metal parts and connected and reinforced with bolts, which can further improve the overall strength of the two reinforcing ribs 36.

[0039] 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 the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
