Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, specifically to an installation structure for U-shaped channel sidewall formwork. Background Technology

[0002] In recent years, with the acceleration of urbanization and the increase in extreme weather events, urban flooding has become an increasingly prominent problem, posing a significant threat to urban safety and the quality of life for residents. To effectively address this challenge, the field of water conservancy design and construction has continuously explored and innovated. Among these innovations, newly constructed U-shaped drainage channels and other structural forms have demonstrated significant advantages in preventing urban flooding due to their excellent drainage performance and structural stability. The design and implementation of these drainage channels are of great significance for improving urban flood control and drainage capabilities and ensuring the healthy operation of the urban water cycle system.

[0003] However, in the construction of water conservancy facilities such as U-shaped channels, the traditional process of installing and reinforcing wooden formwork in the sidewall construction stage faces a series of technical and efficiency bottlenecks. Specifically, the installation and reinforcement process of wooden formwork is time-consuming, which not only increases construction costs but may also lead to delays in the overall project schedule. In addition, wooden formwork is easily damaged during demolding, resulting in low reuse rates and further exacerbating the difficulty of controlling construction costs. More importantly, the use of wooden formwork often makes it difficult to guarantee the consistency and stability of the appearance quality of the concrete later, which may lead to surface defects, dimensional deviations, and other problems, thus affecting the overall aesthetics and durability of the water conservancy facilities.

[0004] Of particular concern is that the excessively long installation time of wooden formwork has become a significant factor restricting project schedules. In water conservancy projects with tight deadlines and heavy workloads, the limitations of traditional wooden formwork technology are becoming increasingly apparent, creating an urgent need for a more efficient, economical, and reliable sidewall construction formwork technology to shorten construction cycles, improve project quality, and reduce construction costs. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides an installation structure for U-shaped channel sidewall formwork, which aims to shorten the construction cycle, improve project quality, and reduce construction costs.

[0006] The technical means adopted by this utility model to solve its technical problem is: an installation structure for U-shaped channel sidewall formwork, the improvement of which is that it includes steel sheet pile cross bracing, the steel sheet pile cross bracing spans the U-shaped channel in parallel, and a sliding rail is vertically welded between the steel sheet pile cross bracing, and a number of manual hoists are slidably installed in the sliding rail; sidewall formwork, a number of connecting parts are uniformly welded to the outside of the sidewall formwork, and the connecting parts can be freely connected to the manual hoists.

[0007] The sliding track described in the above technical solution is made of No. 14 I-beam, and the connecting part is made of Φ20 steel bar and set in a hook shape.

[0008] There is a deviation between the sliding track and the spatial position of the side wall formwork in the above technical solution.

[0009] The side wall formwork described in the above technical solution is assembled from standard steel formwork, and steel pipes are used to reinforce the formwork joints both horizontally and vertically.

[0010] The steel sheet pile cross brace described in the above technical solution is provided with adjustable height support feet and adjustable lateral width telescopic devices at both ends.

[0011] The manual hoist described in the above technical solution is equipped with a locking device, which is designed as a two-way ratchet locking mechanism.

[0012] The sliding track described in the above technical solution is equipped with limiting devices on both sides to prevent the manual hoist from exceeding the preset range during the sliding process.

[0013] The above technical solution also includes a shock-absorbing pad between the manual hoist and the sliding rail.

[0014] The beneficial effects of this utility model are:

[0015] Specifically, standard steel formwork of varying quantities is pre-assembled into side wall formwork. I-beams are then used to fabricate sliding rails on the steel sheet pile cross braces of the U-shaped channel section. Hooks are welded onto the pre-assembled side wall formwork and connected to manual hoists installed on the sliding rails to move the formwork vertically and longitudinally, reducing formwork assembly and disassembly time and lowering costs. Attached Figure Description

[0016] Figure 1 This invention provides an installation structure for a U-shaped channel sidewall template. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0019] like Figure 1 As shown, this application provides an installation structure for U-shaped channel sidewall formwork, comprising:

[0020] A sheet pile cross brace 1 is provided, which spans the U-shaped channel in parallel. A sliding rail 2 is vertically welded between the sheet pile cross braces 1, and several manual hoists 3 are slidably installed in the sliding rail 2.

[0021] Side wall template 4, several connectors 5 are evenly welded to the outside of the side wall template 3, and the connectors 5 can be freely connected to the manual hoist 3.

[0022] In one possible implementation, the sliding track 2 is made of No. 14 I-beams, and the connector 3 is made of Φ20 steel bars arranged in a hook shape.

[0023] Specifically, No. 14 I-beams are welded to the steel sheet pile cross braces on both sides of the already poured 30m side wall and the 30m side wall to be constructed as template sliding tracks (60m on each side of the side wall, for a total of 240m of I-beams). Three force hooks are welded to the outside of each assembled template with Φ20 steel bars as connectors. Three manual hoists are used for hoisting. The three force hooks are evenly distributed on the spliced ​​side wall templates to reduce concentrated stress.

[0024] In one possible implementation, there is a deviation between the sliding track 2 and the spatial position of the side wall template 4.

[0025] Specifically, since the side wall formwork needs to be lifted upwards, attention should be paid to the welding position of the I-beams during welding. They should not be welded directly above the side wall formwork. Operational space should be left for the formwork to slide. The connection between the I-beams should be on the same straight line and at the same height. Unevenness will affect the sliding effect.

[0026] In one possible implementation, the side wall formwork 4 is assembled from standard steel formwork, and steel pipes are used to reinforce the formwork joints both horizontally and vertically.

[0027] Specifically, based on a standard steel formwork length of 1.5m, the entire 30m section of sidewall formwork is assembled from 20 standard 6015 steel formwork panels. On-site, three fixed sidewall formwork panels were actually assembled into lengths of 10.5m (7 panels), 10.5m (7 panels), and 9m (6 panels). Steel pipes were used for horizontal and vertical reinforcement at the formwork joints to reduce assembly time. After one section of the sidewall was poured, the formwork was removed only at the joint between these three sections; other sections were not removed. If there were connecting steel pipes between the joints, tools were used to separate them.

[0028] In one possible implementation, the two ends of the sheet pile cross brace are respectively provided with height-adjustable support feet and lateral width-adjustable telescopic devices.

[0029] Specifically, the support feet are height-adjustable via threaded or hydraulic adjustment to adapt to different terrains and variations in the depth of the U-shaped channel; the telescopic device, through built-in slide rails and locking mechanisms, is precisely adjusted according to the actual width of the U-shaped channel to ensure that the steel sheet pile cross bracing remains horizontal and stable when spanning the U-shaped channel, effectively resisting the lateral pressure generated during the pouring process.

[0030] In one possible implementation, the manual hoist is equipped with a locking device designed as a two-way ratchet locking mechanism.

[0031] Specifically, the bidirectional ratchet locking mechanism can effectively lock when the manual hoist is pulled up or down, preventing the template from moving due to unexpected situations (such as wind, vibration, etc.). In addition, the handle of the manual hoist is equipped with a non-slip grip and a labor-saving lever design, making it easy for operators to adjust the template while ensuring safety.

[0032] In one possible implementation, limiting devices are provided on both sides of the sliding track to prevent the manual hoist from exceeding the preset range during sliding, thus ensuring the accuracy of the template installation position.

[0033] Specifically, the limiting device is made of wear-resistant and corrosion-resistant materials, possessing sufficient strength and rigidity to ensure that it does not deform or become damaged during long-term use. The installation position of the limiting device should be precise, maintaining a certain gap with the end face of the sliding rail to avoid affecting the sliding performance of the manual hoist due to excessive friction.

[0034] In one possible implementation, a shock-absorbing pad is also provided between the manual hoist and the sliding rail.

[0035] Specifically, the shock-absorbing pad is made of highly elastic rubber material, and its thickness and hardness are precisely calculated. It can effectively absorb vibration and noise, and ensure the smoothness and stability of the manual hoist during the sliding process.

[0036] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
