Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a self-stabilizing support template frame for channel lining construction. Background Technology

[0002] Channel lining is a widely used construction technique in water conservancy projects to prevent leakage and improve water conveyance efficiency. Its construction quality largely depends on the stability of the formwork during concrete pouring. As a key piece of equipment to ensure that the formwork does not deform or shift during construction, the structural performance of the supporting formwork frame directly affects the forming quality of the channel lining.

[0003] In actual canal engineering, due to factors such as topography and design flow rate, the cross-sectional dimensions of the canal, especially its width, are often not constant and may vary in different sections of the same project. This places high demands on the applicability of the supporting formwork. Currently, most of the supporting formwork used on construction sites are fixed-size steel structures. When encountering canal sections with varying cross-sectional dimensions, these fixed formwork frames become unsuitable. Construction units have to pre-order and prepare various specifications of formwork frames, which not only significantly increases the manufacturing cost of equipment and the burden of warehousing management, but also consumes a lot of time in the process of replacing and transporting different specifications of formwork frames, seriously affecting the construction progress.

[0004] To overcome the aforementioned problems, some simple adjustable support frames have emerged. However, the adjustment methods for these devices are usually cumbersome, involving the disassembly and reassembly of numerous bolts or relying on multi-position pins for coarse adjustments. This method is not only inefficient, requiring multiple workers to coordinate, but also lacks precision, making it difficult to accurately conform to the actual contours of the channel, thus affecting the support effect of the formwork and the molding accuracy of the concrete. Therefore, designing a support formwork frame that can be quickly, conveniently, and accurately adjusted to adapt to the construction needs of channels of different specifications has become a pressing technical problem in this field.

[0005] Therefore, this utility model proposes a self-stabilizing support template frame for channel lining construction to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a self-stabilizing support template frame for channel lining construction, aiming to improve the problems of fixed structural dimensions, difficulty in adapting to different channel specifications, and lack of safety protection structure in the existing support template frame.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a self-stabilizing support template frame for channel lining construction, comprising: a support frame, a support member fixedly connected to the support frame, and an adjustable mechanism; The adjustable mechanism connects and supports two different parts of the bracket and is used to adjust the distance between the two different parts. It includes an outer rod and an inner rod that slides within the outer rod. The adjustable mechanism further includes a housing, a bearing seat, a rotating shaft, and a locking block. The housing is fixedly connected to the end of the outer rod, the bearing seat is installed inside the housing, the rotating shaft is rotatably connected to the bearing seat, the locking block is fixedly connected to the rotating shaft, and a groove is provided on the end of the outer rod for selectively engaging with the locking block.

[0008] Preferably, the bottom of the support member is fixedly connected to a downwardly extending fixing foot.

[0009] Preferably, the bracket is composed of multiple rods that are fixed together by bolts.

[0010] Preferably, it also includes a protective mechanism, which is fixedly connected to the support member via a connecting seat.

[0011] Preferably, the protective mechanism includes uprights and crossbars connecting the uprights.

[0012] Preferably, the protective mechanism further includes a kick plate, which is fixedly connected to the bottom of the upright.

[0013] Preferably, the inner wall of the outer casing is provided with a slot for mounting the bearing seat.

[0014] Preferably, the outer rod and the outer shell are configured as an integral rotating structure, which is used to synchronously drive the rotating shaft to rotate when the outer rod is rotated.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problems of fixed support template frame size, difficulty in adapting to different specifications of channels, and poor versatility in the prior art by setting an adjustable mechanism with an inner and outer rod telescopic structure and a locking device for rotating clamps. It achieves the technical effect of being able to quickly and conveniently adjust the size of the template frame, accurately adapt to different construction environments, and significantly improve construction adaptability and efficiency.

[0016] 2. This utility model solves the problem that existing formwork frames generally lack systematic safety protection measures, resulting in safety hazards such as workers falling from heights and materials falling, by integrating and fixing the protective mechanism, which includes horizontal bars, vertical bars and kick plates, onto the support components. It achieves the technical effect of forming a comprehensive safety protection system that is stable and synchronized with the formwork frame, effectively protecting the personal safety of construction workers, avoiding the risk of falling objects from heights, and improving the overall construction safety level.

[0019] 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.

[0020] Reference Figures 1-4 The present invention provides an embodiment of a self-stabilizing support template frame for channel lining construction, comprising a support 4 and a support member 2 fixedly connected to the support 4; the support 4 is composed of multiple rods fixedly connected to each other by bolts 6, and the bottom of the support member 2 is fixedly connected with a downwardly extending fixed foot 3 for inserting into the bottom wall of the channel to provide lateral support; an adjustable mechanism 5 is connected and supported between two different parts of the support 4, and the adjustable mechanism 5 is used to adjust the distance between the two different parts, so that the entire template frame can adapt to water channels 1 of different widths; The support member 2 is also fixedly connected to the protective mechanism 7 via the connecting seat 704. The protective mechanism 7 provides safety for the construction area. The adjustable mechanism 5 includes an outer rod 501 and an inner rod 502 that slides within the outer rod 501. The length is adjusted by the relative extension and retraction of the outer rod 501 and the inner rod 502. The adjustable mechanism 5 is also equipped with a locking component for locking the relative position of the inner and outer rods. The locking component includes a housing 506, a bearing seat 503, a rotating shaft 504, and a locking block 505. The protective mechanism 7 includes several uprights 702. A horizontal bar 701 is connected between the uprights 702. A kick plate 703 is fixedly connected to the bottom of the uprights 702. The horizontal bar 701, the uprights 702, and the kick plate 703 together form a complete protective frame. The telescopic body of the adjustable mechanism 5 consists of an outer rod 501 and an inner rod 502 that slides inside the outer rod 501. Its locking assembly is mainly located at the end of the outer rod 501. A housing 506 is fixedly connected to the end of the outer rod 501. A slot for installing a bearing seat 503 is provided on the inner wall of the housing 506. The bearing seat 503 is installed in the slot within the housing 506. The bearing seat 503 provides rotational support for the rotating shaft 504, which is rotatably connected to the bearing seat. 503, and the locking block 505 is fixedly connected to the rotating shaft 504, so that the locking block 505 can rotate synchronously with the rotating shaft 504. The outer rod 501 and the outer shell 506 are set as an integral rotating structure. This setting is used to drive the outer shell 506 and the internal rotating shaft 504 to rotate synchronously when the outer rod 501 is rotated. A groove is opened on the end of the outer rod 501. The shape and size of the groove are adapted to the locking block 505, so as to achieve selective engagement with the locking block 505 at a specific angle. When the length needs to be adjusted, rotate the outer rod 501. The outer rod 501 drives the rotating shaft 504 to rotate, which in turn causes the locking block 505 to rotate out of the slot and release the lock. At this time, the inner rod 502 can be pulled freely. When the adjustment is in the appropriate position, rotate the outer rod 501 in the opposite direction to make the locking block 505 rotate back and lock into the slot, thus completing the stable locking of the relative position of the inner and outer rods. The whole process is convenient to operate and the locking is reliable. In order to enhance the overall formwork frame’s ability to resist lateral overturning and to firmly anchor it to the channel foundation, the bottom of the support member 2 is fixedly connected with a downwardly extending fixing foot 3, which can be cone-shaped to facilitate insertion into the soil or cushion layer at the bottom of the channel. To improve the overall structural strength and stability of the support 4, the support 4 is composed of multiple rods that are fixed together by bolts 6. This method of connection by bolts 6 facilitates quick assembly and disassembly on site, while also ensuring the reliability of the connection. To provide comprehensive safety during construction, a protective mechanism 7 is also included. The protective mechanism 7 is fixedly connected to the upper part of the support member 2 via a connecting seat 704. The connecting seat 704 can be a welded or bolted connection structure. The protective mechanism 7 includes multiple vertically arranged uprights 702 and horizontal bars 701 connected between the uprights 702 in the horizontal direction. The uprights 702 and the horizontal bars 701 together constitute the main body of the guardrail. To prevent small objects such as tools or materials from accidentally falling from the high-altitude work platform, the protective mechanism 7 also includes a kick plate 703, which is fixedly connected to the bottom of the upright 702 and extends along the edge of the work platform of the template frame.

[0021] Working principle: In the construction preparation stage, the entire support template frame is first placed in the water channel 1. The adjustable mechanism 5 is operated to adapt to the size of the water channel 1. Specifically, the outer rod 501 is rotated. The outer rod 501 drives the internal rotating shaft 504 to rotate in the bearing seat 503 through the outer shell 506 that rotates with it. The rotation of the rotating shaft 504 causes the locking block 505 fixed on it to rotate to the unlocked position. At this time, the locking block 505 is disengaged from the slot opened on the outer rod 501. Then the inner rod 502 can be pulled or pushed freely to change the total length of the adjustable mechanism 5. When it is adjusted to precisely match the width of the water channel 1, the outer rod 501 is rotated in the opposite direction to make the locking block 505 re-screw in and lock into the slot, thereby completing the quick and stable locking of the entire support frame 4. After adjusting and locking the dimensions, the fixing feet 3 at the bottom of the support member 2 are forcefully inserted into the soil of the channel bottom wall. The anchoring force provided by the foundation is used to resist the lateral thrust generated during subsequent concrete pouring. At the same time, the protective mechanism 7, consisting of the horizontal bar 701, the vertical bar 702, and the kick plate 703, is firmly set on the support member 2 through the connecting seat 704, providing reliable safety protection for construction personnel working at height. The kick plate 703 can effectively prevent tools and other materials from falling accidentally. The entire load-bearing structure, consisting of the bracket 4, the support member 2, and the bolts 6, safely transfers the load of the formwork and concrete to the channel foundation, ensuring the self-stabilizing state and forming quality of the construction process.
