Description

Technical Field

[0001] This utility model belongs to the technical field of temporary support devices, specifically relating to a segmented, assembled temporary support device for corrugated steel pipe construction. Background Technology

[0002] When segmented corrugated steel pipes are spliced ​​and fixed to form a culvert, temporary support is required to prevent them from rolling. This is usually done through temporary support devices, and the existing temporary support devices are support frames to prevent the segmented corrugated steel pipes from rolling during construction and placement after installation. Existing segmented corrugated steel pipes are assembled and fixed by directly welding the segments together. This makes temporary support difficult during installation, leading to inaccurate welding due to manual alignment or instability under external forces, thus reducing welding efficiency and affecting the convenience of temporary support and welding accuracy during the fixed installation of segmented corrugated steel pipes. To address this issue, this utility model proposes a temporary support device for the construction of segmented corrugated steel pipes. Utility Model Content

[0003] The purpose of this utility model is to provide a temporary support device for the construction of segmented corrugated steel pipes, in order to solve the problem mentioned in the background art that when segmented corrugated steel pipes are assembled and fixed, the segmented corrugated pipes are directly spliced ​​together and welded, which makes it inconvenient to provide temporary support during the fixed installation, and causes inaccurate welding and reduced welding effect when manual alignment or unstable external force is applied.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a segmented assembly type temporary support device for corrugated steel pipe construction, including side support frames, a reinforcing crossbar fixed between two side support frames by welding, an end plate fixed at one end connection of the two side support frames, an auxiliary pushing and pressing mechanism provided at the end of the side support frame, and a reinforcing embedding mechanism provided on both sides of the auxiliary pushing and pressing mechanism; The auxiliary pushing and pressing mechanism includes a fixed mounting assembly disposed at the end of the side support frame. The fixed mounting assembly is provided with a limit adjustment assembly inside. An auxiliary pushing assembly is provided at the connection between the end of the limit adjustment assembly and the end of the side support frame. The reinforcing embedding mechanism includes a support mounting assembly welded and fixed to both sides of the fixed mounting assembly. The reinforcing embedding assembly is provided at the bottom of the inner part of the support mounting assembly, and guide sliding assemblies are provided at the top of both sides of the reinforcing embedding assembly.

[0005] Preferably, the fixed installation assembly includes a mounting base disposed on one side of the ends of the two side support frames, and a fixing plate is welded and fixed to the ends of the side support frames between the two reinforcing crossbars.

[0006] Preferably, the limiting adjustment component includes a limiting groove formed inside the mounting base, and a reinforcing bolt is threadedly connected to the middle position of the rear surface of the mounting base.

[0007] Preferably, the auxiliary pushing component includes a limiting connecting plate that is limited inside the limiting groove. A push rod is welded to both ends of one side of the limiting connecting plate. The end of the push rod is fixed to the surface of the fixing plate by welding. The end of the reinforcing bolt is connected to the inside of the limiting connecting plate by a bearing.

[0008] Preferably, the support mounting assembly includes columns welded and fixed to both ends of the mounting base, with a reinforcing threaded rod threadedly connected to the top of the column, and a handwheel welded and fixed to the top of the reinforcing threaded rod on the upper surface of the column.

[0009] Preferably, the reinforcing embedded component includes a slide seat disposed inside the column, the bottom end of the slide seat is integrally provided with an embedded reinforcing rod, the bottom end of the column is provided with a through hole, and the embedded reinforcing rod passes through the inside of the through hole, the bottom end of the embedded reinforcing rod is welded and fixed with a tapered head, and the bottom end of the reinforcing threaded rod is connected to the inside of the slide seat through a bearing.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By designing an auxiliary pushing and clamping mechanism, temporary support devices can be used to temporarily support the segmented corrugated pipes during construction. When the temporary support is unstable when placed directly, the mounting base is fixed at the construction site. When the reinforcing bolt is rotated again, the limit connecting plate drives the top rod to apply thrust. The fixing plate and the reinforcing crossbar then drive the side support frame forward to assist in the reinforcement installation. This ensures that the surface of the side support frame is always in contact with the surface of the corrugated pipe, facilitating temporary reinforcement and preventing loosening or instability when subjected to external forces during construction. This allows for precise construction and effectively prevents rolling after construction, improving the convenience of the temporary support device in assisting in the reinforcement of segmented assembled steel corrugated pipes.

Detailed Implementation

[0013] 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.

[0014] Please see Figures 1 to 6 This utility model provides a technical solution: a segmented assembly type temporary support device for corrugated steel pipe construction, including a side support frame 101, a reinforcing crossbar 102 fixed between two side support frames 101 by welding, an end plate 103 fixed at one end of the connection between the two side support frames 101, an auxiliary pushing and pressing mechanism is provided at the end of the side support frame 101, and a reinforcing embedding mechanism is provided on both sides of the auxiliary pushing and pressing mechanism; The auxiliary pushing and pressing mechanism includes a fixed installation component set at the end of the side support frame 101. The fixed installation component is equipped with a limit adjustment component inside. An auxiliary pushing component is set at the connection between the end of the limit adjustment component and the end of the side support frame 101. When the temporary support device supports the segmented assembled corrugated steel pipe during construction, the auxiliary pushing and pressing mechanism can assist in pushing forward again to adjust and tightly fit the installation, which is less likely to cause instability, ensures precise construction, and effectively prevents rolling after construction.

[0015] In order to facilitate the installation of the auxiliary adjustment component through the fixed installation component, and to enable the temporary support device to be adjusted forward and closely fit the support after installation without easily creating gaps, in this embodiment, preferably, the fixed installation component includes a mounting base 1012 disposed on one side of the ends of the two side support frames 101, and a fixing plate 1011 is welded and fixed to the ends of the side support frames 101 between the two reinforcing crossbars 102, which facilitates installation and adjustment.

[0016] In order to facilitate the limited movement adjustment of the limiting connecting plate 1014 by means of the limiting adjustment component, in this embodiment, preferably, the limiting adjustment component includes a limiting groove 1013 opened inside the mounting base 1012, and a reinforcing bolt 1016 is threadedly connected to the middle position of the rear surface of the mounting base 1012. The reinforcing bolt 1016 can be rotated on the rear surface of the mounting base 1012 to drive the limiting connecting plate 1014 to move within the limiting groove 1013.

[0017] To facilitate the forward pushing and reinforcement of the fixed plate 1011 and the side support frame 101 using the auxiliary pushing assembly, in this embodiment, preferably, the auxiliary pushing assembly includes a limiting connecting plate 1014 that is limited inside the limiting groove 1013. Top rods 1015 are welded to both ends of one side of the limiting connecting plate 1014. The ends of the top rods 1015 are fixed to the surface of the fixed plate 1011 by welding. The ends of the reinforcing bolts 1016 are connected to the interior of the limiting connecting plate 1014 via bearings. When the limiting connecting plate 1014 moves in a limited position, it can drive the top rods 1015 to move. The movement of the two top rods 1015 provides tight support for the fixed plate 1011 and the side support frame 101 as they push forward, ensuring close contact with the corrugated pipe surface. This prevents gaps that could cause wobbling and instability. Therefore, when pushing forward, the resistance of the bottom end of the side support frame 101 contacting the ground is less than the thrust applied when rotating the bolt, allowing for smooth forward movement and reinforcement.

[0018] The reinforcing embedding mechanism includes a support mounting component welded and fixed to both sides of the fixed mounting component. The bottom of the support mounting component is provided with a reinforcing embedding component, and the top of both sides of the reinforcing embedding component is provided with a guide sliding component. After the mounting base 1012 is placed, the mounting base 1012 can be reinforced and installed by embedding it into the ground through the reinforcing embedding mechanism at its ends, which facilitates the smooth adjustment of the auxiliary support for reinforcement.

[0019] To facilitate the reinforcement and support of the mounting base 1012 during adjustment using the support mounting assembly, in this embodiment, preferably, the support mounting assembly includes columns 104 welded and fixed to both ends of the mounting base 1012. The top end of the column 104 is threadedly connected to a reinforcing threaded rod 1047. The top end of the reinforcing threaded rod 1047 is welded and fixed to the upper surface of the column 104. After the mounting base 1012 and the column 104 are placed in a certain position, the handwheel 1041 can be held at the top end of the column 104 to rotate the reinforcing threaded rod 1047, which facilitates the rotation and adjustment of the reinforcing threaded rod 1047 to assist in the reinforcement and installation.

[0020] To facilitate the embedding of the mounting base 1012 and the column 104 into the ground for reinforcement during support, in this embodiment, preferably, the reinforcement embedding component includes a slide 1043 disposed inside the column 104. An embedded reinforcement rod 1046 is integrally provided at the bottom end of the slide 1043. A through hole 1042 is provided at the bottom end of the column 104, and the embedded reinforcement rod 1046 passes through the through hole 1042. A tapered head 1044 is welded and fixed to the bottom end of the embedded reinforcement rod 1046. The bottom end of the reinforcing threaded rod 1047 is connected to the interior of the slide 1043 via a bearing. When the slide 1043 is subjected to downward force, causing the embedded reinforcement rod 1046 to move downward, the tapered head 1044 contacts the ground, embedding the embedded reinforcement rod 1046 into the ground for reinforcement, facilitating temporary support during reinforcement installation.

[0021] To facilitate the stable downward movement of the slide block 1043 and the embedded reinforcing rod 1046 via the guide sliding assembly, in this embodiment, preferably, the guide sliding assembly includes guide grooves 1049 formed on both sides inside the column 104. A guide slider 1048 is integrally provided on the side of the slide block 1043. The guide slider 1048 is slidably connected to the inside of the guide groove 1049, so that the guide slider 1048 can slide inside the guide groove 1049 when the slide block 1043 moves downward, which facilitates the stable downward movement and reinforcement installation of the slide block 1043 and the embedded reinforcing rod 1046. The bottom end of the column 104 is fixed with a scraper ring 1045 by bolts, and the outer surface of the embedded reinforcing rod 1046 contacts the inner surface of the scraper ring 1045. After the support is used, the dirt generated on the outer surface when the embedded reinforcing rod 1046 is removed from the ground is scraped and cleaned by the scraper ring 1045.

[0022] The working principle and usage process of this utility model: When using this kind of segmented assembled corrugated steel pipe construction temporary support device, the segmented assembled corrugated steel pipe is first assembled. At this time, the end plate 103 contacts the bottom end of the side of the corrugated pipe, and the inner arc structure of the side support frame 101 contacts the surface of the corrugated pipe for temporary support. Then, when the side support frame 101 is in temporary support, the bottom end of the column 104 is placed on the ground along with the mounting base 1012. The handwheel 1041 is used to rotate the reinforcing threaded rod 1047. When the reinforcing threaded rod 1047 is rotated, the slide block 1043 slides inside the column 104. At the same time, the guide slider 1048 guides the slide block 1043 and the embedded reinforcing rod 1046 to move down stably. The embedded reinforcing rod 1046 passes through the hole 1042 and is embedded into the ground by the conical head 1044. The embedded reinforcing rod 1046 is embedded into the ground for reinforcement and installation. This makes it convenient to fix the mounting base 1012 in a certain position. Therefore, it is not easy to cause instability when adjusting and assisting reinforcement inside the mounting base 1012, which improves the reinforcement stability of the mounting base 1012 during the construction of segmented assembled corrugated steel pipes. Finally, after the mounting base 1012 is fixedly installed, the side support frame 101 abuts against the surface of the segmented assembled corrugated steel pipe. The wrench is engaged on the surface of the reinforcing bolt 1016, causing the reinforcing bolt 1016 to rotate. When the reinforcing bolt 1016 is rotated, the limiting connecting plate 1014 slides inside the limiting groove 1013. When the limiting connecting plate 1014 slides, it causes the two push rods 1015 to apply a pushing force. Through the fixing plate 1011 and the reinforcing crossbar 102, the side support frame 101 is pushed forward again to assist in the reinforcement installation, so that the surface of the side support frame 101 is always in contact with the surface of the corrugated pipe. This facilitates temporary reinforcement and is less likely to cause loosening or instability when subjected to external forces during construction, allowing for precise construction. It also effectively prevents rolling after construction, improving the convenience of the temporary support device in assisting in the reinforcement of segmented assembled corrugated steel pipes.
