Description

A non-ground-type pier column cap beam template disassembly and assembly equipment and construction method Technical Field

The invention relates to the field of construction engineering, and in particular to a non-ground-type pier cap beam formwork disassembly and assembly device and a construction method.

Background technique

With the vigorous promotion of quality engineering and safe and civilized construction, the traditional operating platform of bridge engineering construction is gradually unable to meet the existing construction requirements. Before installing the traditional round pier column cap beam formwork, a special scaffolding needs to be set up, which has strict requirements on the foundation. The erection and dismantling of the ground scaffolding is a risky process in the bridge industry. All steel materials on the traditional cap beam formwork, including side formwork, steel wedges, bottom formwork panels, load-bearing beams, steel hoops, etc., need to be installed piece by piece using a crane. Since the cap beam has been completed at this time, it is difficult to dismantle the formwork and other steel materials piece by piece. The dismantling operation is carried out at high altitude, and the safety risk of the operators is high. Most of the current cap beam construction adopts the method of bulk loading in the air, especially the dismantling construction, which is more dangerous. The conventional disassembly and assembly methods are as follows: (1) Conventional installation: When installing and disassembling the conventional cap beam formwork, a special ground scaffolding needs to be set up. When installing the cap beam formwork, the operators use the ground scaffolding. (2) Conventional dismantling: When dismantling the cap beam formwork, the operators also use the scaffolding and crane to dismantle all the components of the cap beam formwork piece by piece.

technical problem

In the prior art, the cap beam is poured after the cap beam formwork is installed. After pouring, the formwork is lowered by a tower crane or a crane. In the process of processing and pouring the cap beam, the tower crane or the crane needs to be used for a long time, and the installation process is individual and a large number of scaffolding structures will be used. The overall installation time is long and the dismantling efficiency is low. When installing some higher piers, there will be greater safety hazards. The overall safety and accuracy are poor, the construction is slow and the risk is high.

Industrial Applicability

The overall assembly and disassembly process of the cap beam construction platform, through detailed structural design and processing of some special components, achieves modularization of platform installation and disassembly, realizes the standardization and normalization of bridge cap beam construction, and achieves the purpose of convenient, efficient and safe installation and disassembly. Especially for special working conditions such as water cap beam engineering projects, it has important application significance and promotion value.

The overall disassembly and assembly system of the platform mainly consists of longitudinal beams, cross beams, outriggers, winch power system, hanger and formwork platform. Among them, the core component of the overall disassembly and assembly system of the platform is the winch located at the top. The winch is an ordinary variable speed winch with a single drum. Since the construction process requires the four corners of the cap beam platform to be lowered synchronously, the winch needs to be modified so that the four winches are connected to a main switch at the same time in addition to the sub-switches. When the winches are working, they can ensure that the wire ropes are retracted or released at the same time to ensure the synchronous lifting or lowering of the platform.

The platform has a high self-weight. In order to avoid the single-strand tension of the winch being insufficient and improve the safety performance of the system, the "two-way" winding method (double rate) is used when winding the wire rope to increase the tension and improve the safety factor. The method of using the overall assembly and disassembly system of the cap beam platform for construction can greatly save the machinery cost in each cap beam construction cycle, and at the same time can save at least 1.5 to 2.0 days of construction period, speeding up the construction progress. With this construction method, there is no need to set up a ground scaffolding, but a special steel clamp installation and disassembly platform is installed, which is easy to operate and has a high safety factor. The system is used to dismantle the cap beam template. All templates are decomposed and dismantled on the ground. There is no high-altitude operation, and only simple lifting and hoisting are involved, so the safety factor is relatively large. This device has strong applicability and a wide range of applications, especially for special working conditions such as water cap beam projects. It has good practicality and economy. It can not only be used for the dismantling of the bottom formwork of the round pier cap beam, but also for the dismantling of the bottom formwork of the square pier cap beam. It can reduce the input of labor and machinery shifts and save costs. It has a high safety factor and has a good promotion and application value.

The support device in the present invention is a detachable connection. After the cap beam is processed, the legs and the cross bracing beam are embedded in the cap beam as a keel, which increases the overall firmness of the cap beam, avoids the trouble of later disassembly and assembly, and reduces the construction of the steel frame in the cap beam template. A 3-ton electric hoist is set on the motor support frame, and the electric hoist is fixedly connected through a flange-shaped support seat. In two adjacent support devices, when constructing the steel frame in the cap beam template, tension steel bars or extension beams can be added to increase the stability of the two support devices.

When using the support device, use bolts to connect the cross brace beam and the motor support frame together, and then use bolts to fix the cross brace beam and the legs. Lift the assembled formwork disassembly and assembly equipment as a whole to the top surface of the pier, and anchor the formwork disassembly and assembly equipment to the pier through the pre-embedded fine-rolled threaded steel. When lifting the cap beam formwork, it is only necessary to use the cap beam formwork disassembly and assembly equipment to complete the lifting of the cap beam formwork and the lifting of steel materials and tools. It is easy to use and avoids the tower crane or crane staying near the pier for a long time. In addition, the legs and cross brace beams in the disassembly and assembly equipment of the present invention can be used as the supporting structure of the disassembly and assembly equipment, and can also be used as the keel of the cap beam. After being embedded in the cap beam, it can not only improve the convenience of disassembly of the formwork disassembly and assembly equipment, but also improve the structural strength of the cap beam and reduce the construction of the original steel keel of the cap beam. The overall structure is simple and novel, and highly innovative.
