Description

Technical Field

[0001] The utility model relates to a reinforcement device for a super-high and super-thick pool wall casting template. Background Art

[0002] Tank structures are the core components of sewage treatment plant construction, including biological tanks, high-efficiency sedimentation tanks, and denitrifying deep-bed filters. These structures are characterized by their exceptionally high and thick walls, typically reaching 50 to 80 cm thick at their thickest points and up to 9 meters at their highest. During construction, large volumes of concrete are poured in a single pass, requiring stringent control over cross-sectional dimensions, waterproofing performance, and steel reinforcement protection.

[0003] Although traditional through-thread waterstop screws can effectively control the cross-sectional size and waterproof performance, the manpower cost of removing the waterstop screws after construction is completed is huge. It is often the case that the removed waterstop screw heads are still exposed on the wall, resulting in poor waterproof performance. In the process of removal, excessive external force causes damage to the concrete structure, resulting in poor appearance and even internal water seepage and leakage. The cost is continuously consumed during repeated rectification, and the operation process involves working at height or even in a confined space for a long time, which poses a great safety hazard.

[0004] While existing three-stage waterstop screws can effectively address these issues, the high and thick walls of sewage treatment plant tank structures, coupled with the large volume of concrete being poured, make these screws less stable and insufficiently able to withstand the concrete's own weight. This can easily lead to formwork explosions, potentially causing financial losses or even safety accidents. Therefore, the formwork reinforced with existing three-stage waterstop screws cannot be poured too high in a single pour, typically requiring multiple stages. This not only takes a long time to construct, but also creates multiple construction joints that require additional pre-buried waterstop components, increasing costs while failing to guarantee waterproofing.

[0005] The above two types of water-stop screws have no mandatory control measures for the cross-sectional dimensions of the pool wall and the thickness of the steel bar protective layer. During the construction process, the above cross-sectional parameters are greatly affected by the subjective operation of the operators, making it impossible to guarantee the construction quality.

[0006] The purpose of the utility model is to overcome the defects of the prior art and provide a reinforcement device for ultra-high and ultra-thick pool wall casting formwork, which has the characteristics of easy disassembly, firm and reliable support, and controllable pool wall thickness and steel bar protective layer thickness.

[0007] The purpose of the utility model is achieved as follows: a reinforcement device for ultra-high and ultra-thick pool wall casting template, connected between two pool wall templates; vertical back ribs and horizontal back ribs are fixed on the outer surface of each pool wall template in sequence; the reinforcement device includes several through-wall bolts and two fixing plates;

[0008] Each through-wall bolt includes an inner screw, two outer screws, two reinforcement sleeves and two locking components;

[0009] The total length of the inner screw is between the thickness of the steel frame and the thickness of the pool wall, and the two end surfaces of the inner screw are coaxially provided with internal threaded holes;

[0010] The outer screw is adapted to the inner threaded hole of the inner screw; the inner ends of the two outer screws are connected to the two ends of the inner screw in a one-to-one correspondence;

[0011] The length of the reinforcement sleeve is the thickness of the steel bar protective layer, and a stepped internal threaded hole is provided in the reinforcement sleeve, which is larger inside and smaller outside, that is, the inner threaded hole of the reinforcement sleeve is adapted to the outer thread of the inner screw, and the outer threaded hole of the reinforcement sleeve is adapted to the outer thread of the outer screw; the two reinforcement sleeves are connected one-to-one between the two ends of the inner screw and the inner ends of the two outer screws;

[0012] Two locking assemblies are connected to the outside of the two outer screws in a one-to-one correspondence; each of the locking assemblies includes a mountain-shaped bayonet and a locking nut;

[0013] Each fixing plate is provided with a plurality of through-holes, the diameter of which matches the outer diameter of the inner screw and is smaller than the outer diameter of the reinforcing sleeve; the two fixing plates are respectively fitted on the two ends of the plurality of inner screws through the plurality of through-holes and are respectively attached to the inner and outer surfaces of the steel frame;

[0014] Two pool wall templates are arranged one by one at the outer ends of the reinforcement sleeves at both ends of several inner screws;

[0015] When the two ends of several inner screws are inserted into the several through-holes of the two fixing plates one by one, the two ends of each inner screw are connected to the inner threaded inner hole of a reinforcement sleeve, and the outer threaded inner holes of the two reinforcement sleeves are respectively connected to an outer screw inserted into the through-hole of the pool wall template; a mountain-shaped clamping block and a locking nut are sequentially installed on the outer screw of the transverse back rib exposed on the outer surface of the pool wall template, and the mountain-shaped clamping block is clamped between the two transverse back ribs by rotating the locking nut.

[0016] The above-mentioned reinforcement device for ultra-high and ultra-thick pool wall casting formwork, wherein a water stop plate is fixed to the middle part of the inner screw.

[0017] The features of the reinforcement device for ultra-high and ultra-thick pool wall casting formwork of the utility model are:

[0018] 1. This device uses multiple through-wall screws to coordinate the force, and the inner screw of each through-wall screw is not only mechanically connected between the outer screw and the inner screw, but also reinforced by a reinforcement sleeve. Compared with the three-stage water-stop screw, it greatly improves the stability of the formwork.

[0019] 2. After the demolding is completed, the outer screw can be easily removed by using an electric drill that matches the outer screw and reinforcement sleeve. The removal qualification rate is high, which avoids workers from working at heights and in limited spaces for a long time during the demolition process, effectively reduces the safety hazards in the construction process, and quickly enters the next process. Compared with the traditional threaded water-stop screw, it effectively shortens the construction period and reduces labor costs.

[0020] 3. The length of the reinforcement sleeve in this device is the thickness of the steel bar protective layer. The length of the rod after the inner screw completely penetrates the reinforcement sleeves at both ends is used as the thickness of the pool wall, so as to achieve the effect of rigidly controlling the thickness of the pool wall and the thickness of the steel bar protective layer.

[0021] 4. The reinforcement sleeve and the outer screw in this device can be reused as turnover materials. The reinforcement sleeve can replace the steel bar protective layer pad to realize the control of the thickness of the steel bar protective layer. There is no risk of the pad falling off and affecting the thickness of the local steel bar protective layer, which effectively reduces the construction material cost and labor cost, shortens the construction period and improves the project quality.

[0022] 5. The dismantling method of this device does not cause damage to the internal structure of the concrete or surface cracks due to excessive external force, which will cause poor appearance quality of the concrete or even water seepage and leakage. From the structural design point of view, the internal screw head after dismantling is strictly not exposed to the outer surface of the pool wall, effectively improving the appearance quality and project quality.
