Description

Recyclable cross steel plate baffle device

Technical Field

The invention relates to a recyclable cross steel plate inserting plate type baffle plate device for an underground continuous wall top.

Background

Along with the continuous development of cities, the development and utilization of underground spaces are more and more emphasized by people. The adoption of underground continuous walls for enclosing is more and more accepted by most enterprises, and the cross steel plate joint of the underground continuous walls is the most common, but a plurality of problems exist, such as: the material and processing cost for processing the cross steel plate at the early stage are high; the ring beam is inconvenient to chisel; the cutting of the cross steel plate in the ring beam chiseling construction is troublesome; therefore, it is necessary to develop a recyclable cross steel plate baffle device.

Disclosure of Invention

The invention provides a recyclable cross steel plate inserting plate type baffle device for an underground diaphragm wall, which can be recycled and is convenient to clean and pull out; and the quality of the ground wall is not influenced, and the requirement of ground wall slurry return can be met.

In order to achieve the purpose, the invention adopts the technical scheme that: a recyclable cross steel plate inserting plate type baffle device comprises a cross steel plate baffle and an inserting plate, wherein the cross steel plate baffle and the inserting plate are formed by main steel plates, and the horizontal width of the cross steel plate baffle is reduced by 10-20 mm respectively from the left side to the right side of a guide wall groove section, so that concrete slurry is prevented from flowing outwards; the vertical length of the cross steel plate baffle is at least half of that of the wall ring beam, and the cross steel plate baffle is used for reducing the workload of chiseling off the concrete ring beam in the subsequent process; the end part of the cross steel plate baffle is provided with at least two hoisting points, so that the hoisting is convenient, and the cross steel plate baffle can be fixed with a main reinforcement of a reinforcement cage to play a role in preventing overturning; at least two sets of inserting plates are arranged at the bottom of the cross-shaped steel plate baffle and used for accurately butting the cross-shaped steel plate 6 and the end part of the cross-shaped steel plate baffle.

Notches are formed in two sides of the upper portion of the cross-shaped steel plate baffle, the size of each notch is 10-20 mm, and therefore backflow of slurry is facilitated when concrete is poured.

The hoisting lifting point is connected with the main rib of the underground wall through a fixing piece and used for fixing the cross-shaped steel plate baffle and resisting lateral force.

Each set of plug board consists of two plug boards, the two plug boards are symmetrically welded on two sides of the lower end of the cross-shaped steel plate baffle plate and are beneficial to being inserted into the cross-shaped steel plate of the ground wall, and the depth of the plug boards inserted into the cross-shaped steel plate is more than or equal to 50 mm.

The invention has the beneficial effects that: the method is applied to the enclosure construction stage of the underground continuous wall; the steel plate can be recycled, the steel plate material and the manufacturing cost are saved, and the difficulty in chiseling and cutting the cross steel plate for the ring beam at the later stage can be reduced.

Detailed Description

The invention will be further illustrated with reference to the following specific examples.

As shown in fig. 1 to 3, a cross steel plate baffle device for a ground wall top and capable of being recycled comprises a main steel plate 1, a notch 2, a hoisting lifting point 3, an inserting plate 4 and a fixing piece 5. The main steel plate 1 forms a cross-shaped steel plate baffle, notches 2 are formed in two sides of the middle of the cross-shaped steel plate baffle, and the size h of each notch 2 is 10-20 mm (10-20 mm is reduced inwards); the purpose is to facilitate the backflow of slurry when concrete is poured; at least two hoisting hanging points 3 are arranged at the end part of the cross-shaped steel plate baffle, and the cross-shaped steel plate baffle can be conveniently hoisted through the hoisting hanging points 3 and is conveniently fixed with a main reinforcement 7 of the steel reinforcement cage; the inserting plate 4 is used for enabling the cross-shaped steel plate 6 to be accurately butted with the recyclable cross-shaped steel plate baffle plate device at the end part; at least two inserting plates 4 are arranged according to different groove sections, each inserting plate 4 consists of two inserting plates 4, the two inserting plates 4 are symmetrically welded on two sides of the main steel plate 1, the inserting into the cross-shaped steel plate of the ground wall is facilitated, and the inserting depth of the inserting plates 4 is not less than 50 mm; the fixing piece 5 is a temporary measure for fixing the cross steel plate baffle of the reinforcement cage; the hoisting point 3 is connected with a steel reinforcement cage main reinforcement 7 of the underground diaphragm wall through a fixing piece 5 and used for fixing the cross-shaped steel plate baffle and resisting lateral force. The horizontal width of the cross steel plate baffle is reduced by 10-20 mm for the left and the right of the guide wall groove section respectively, and the cross steel plate baffle is used for preventing concrete slurry from flowing outwards; the vertical length of the cross steel plate baffle is at least half of that of the wall ring beam, and the cross steel plate baffle is used for reducing the workload of chiseling the concrete ring beam in the subsequent process.

This embodiment takes the construction of putting as the example with cooperation underground continuous wall steel reinforcement cage is hung:

after the steel reinforcement cage is completely hoisted into the groove, a hoisting point 3 of the cross-shaped steel plate baffle is hoisted into the groove section by a crane, so that the inserting plate 4 is butted with a cross-shaped steel plate 6 of the steel reinforcement cage, and then the baffle device is fixed with an underground wall main rib 7 by using a fixing piece 5 with certain rigidity, so that the stability of the baffle is ensured; after the concrete is poured and before the final setting time, it is pulled out, and the crane is flushed clean from the ground for reuse.
