Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a novel tie-rod-free template used for enhancing the anti-leakage of a pool wall. Background Art

[0002] In chemical and petrochemical plants, and in sewage treatment plants, accident pools must be set up to store accident water in emergency situations. Once a production accident occurs in these plants, a large amount of high-concentration organic wastewater with large pH fluctuations will be discharged into the accident pool in a short period of time. Therefore, the pouring quality of the accident pool concrete is very high, especially the integrity and anti-leakage performance of the pool wall. However, in the past, the construction was based on a formwork structure of wooden formwork + plate support + tie rod + inclined external support. Due to the uncontrollable degree of sealing of the tie rod hole, leakage will occur at the tie rod hole position. Therefore, how to effectively prevent water seepage at the tension bolts of the pool wall has become a key issue in the waterproofing of rainwater accident pools.

[0003] In addition, the accident pool is generally very deep and the pool wall is very high. It is difficult to vibrate the lower part when pouring concrete, which will affect the pouring quality. Summary of the invention

[0004] In order to solve the above problems, the utility model discloses a new type of tie rod-free formwork used to enhance the anti-leakage performance of the pool wall. By adopting the lightweight tie rod-free steel formwork technology, there is no need to seal the tie rod holes after the concrete of the pool wall is poured, thereby ensuring the anti-leakage performance of the pool wall concrete. An attached vibrator is also used to assist in vibration. This construction method can meet the engineering technical requirements and speed up the construction progress, thereby achieving the expected effect.

Vertical ribs are welded on the outside of the transverse ribs, and the upper ends of the vertical ribs are higher than the height of the panels. The vertical ribs at the rear ends of the two panels correspond to each other one by one and are connected at the top by threaded steel tie rods. The fixed plate is L-shaped, and the vertical surface of the fixed plate is fixed to the outside of the vertical ribs. The horizontal surface of the fixed plate is connected to the foundation below. The vibrator is adsorbed on the bottom of the back of the panel.

[0007] As an improvement of the utility model, vertical stiffening ribs are provided between the transverse ribs.

[0008] As an improvement of the utility model, both ends of the threaded steel pull rod are locked by nuts.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0021] As shown in the figure, the utility model describes a new type of tie rod-free formwork for enhancing the anti-leakage of the pool wall, including a panel 1, vertical ribs 2, transverse ribs 3, a fixed plate 4 and a vibrator 5. The two panels 1 are vertically arranged opposite to each other, and a plurality of transverse ribs 3 are provided on the back of the panel 1. The vertical ribs 2 are welded on the outside of the transverse ribs 3. The upper ends of the vertical ribs 2 are higher than the height of the panels 1. The vertical ribs 2 at the rear ends of the two panels correspond to each other one by one and are connected at the top by threaded steel tie rods 6. The fixed plate 4 is L-shaped, and the vertical surface of the fixed plate 4 is fixed to the outside of the vertical ribs 2. The horizontal surface of the fixed plate 4 is connected to the foundation below. The vibrator 5 is adsorbed on the lower back of the panel 1.

[0022] The utility model describes a new type of tie-rod-free formwork for enhancing the anti-leakage of the pool wall. Taking an industrial park in a certain district of Zhangjiagang City as an example, the accident pool is 5.3m deep, 30m long, 25m wide, and the pool wall is 0.4m thick. The outer templates of the pool wall are all adjustable tie-rod-free high-precision templates, and the inner templates are assembled from flat rigid templates.

[0023] The inner and outer templates are composed of panels + steel structures, where panel 1 is made of 5mm thick steel plate; the transverse ribs 3 are made of No. 12 channel steel, spot welded to the panel at a spacing of 400mm, and the weld length is not less than 30mm; No. 40 double-jointed channel steel is used as the vertical ribs 2, with a spacing of 1500mm; the lower foot of each vertical rib 2 is reinforced with pre-buried 25 diameter connecting bolts to resist the template foot. The top crosses the 25 diameter fine-rolled threaded steel for tensioning, and the two ends are locked by nuts 8; the template is assembled once as a whole, which is quick to disassemble and install, and safe and convenient to use.

[0024] The utility model provides vertical stiffening ribs 7 between the transverse ribs 2. The stiffening ribs 7 are made of 55×6mm flat steel and are spot welded to the back of the panel at a spacing of 300mm.

[0025] The horizontal surface of the fixing plate 4 of the utility model is provided with a connecting hole 9, which is fixedly connected to the foundation below by pre-buried connecting bolts 10.

[0026] There are three connecting holes 9 arranged in an isosceles triangle, which can better fix the lower part of the vertical rib 2.

[0027] During pouring, the concrete is poured in layers and sections in a continuous manner, with a pouring height of no more than 0.5m per hour. The concrete is poured in layers and sections in sequence, and a vibrator is set at the bottom to vibrate and compact it. During the vibration, the concrete is observed to no longer sink, no longer emit bubbles, and the surface is slurry, and it is level and shiny, then the vibration can be stopped.
