Description

Technical Field

[0001] The invention belongs to the field of building construction, and in particular relates to a super-high construction joint structure and a construction method. Background Art

[0002] In some special buildings such as theaters, auditoriums, and garbage transfer stations, there are sometimes super-high construction joints of more than 10 meters. The use of traditional construction joint structures will cause serious leakage during the construction process. At the same time, the water-stop steel plate is prone to tilt during the construction process, affecting the waterproof effect of the construction joint.

[0003] Therefore, it is necessary to continuously invent and improve structures and construction methods suitable for super-high construction joint construction to ensure the construction quality of super-high construction joints. A super-high construction joint structure and construction method are proposed for super-high construction joint construction based on this requirement. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a super-high construction joint structure and a construction method.

[0005] This super-high construction joint structure includes a wall, a corrugated steel plate and a waterstop steel plate. Half of the waterstop steel plate is embedded in the wall and the other half is exposed. The front and back of the waterstop steel plate are connected to a corrugated steel plate by welding respectively, and the corrugated steel plate is tightly connected to the wall section.

[0006] Preferably, a plurality of structural ribs are evenly arranged at the front and rear ends of the wall, and the structural ribs penetrate the corrugated steel plate.

[0007] Preferably, the corrugated steel plate is welded from a number of corrugated surfaces, the welding point between two adjacent corrugated surfaces is a convex point of the corrugated steel plate; each corrugated surface is an obtuse-angled opening, a number of stripes are arranged on each corrugated surface, a group of anchor bars are welded on each corrugated surface, and a concrete density test hole with a diameter of about 1 cm is arranged at the lower end of each corrugated surface.

[0008] Preferably, the group of anchor bars consists of three threaded steel bars, two of which are welded to the waterstop steel plate.

[0009] Preferably, the templates at the front and back of the wall are connected by screws.

[0010] The construction method of the super-high construction joint structure comprises the following steps:

[0011] S1. Making corrugated steel plates: According to the height and thickness of the super-high construction joint, select the corrugated surface of appropriate size, and weld several corrugated surfaces into corrugated steel plates.

[0012] S2. Preparation before construction: transport the materials required for construction to the site and clean up the construction site.

[0013] S3. Formwork work: Arrange structural reinforcement according to the height and thickness of the super-high construction joint, set up formwork of corresponding size, connect the formwork through screws, fix waterstop steel plates at the construction joints, weld a piece of corrugated steel plates in front and behind the waterstop steel plates, block the concrete density test holes on all the corrugated surfaces, and weld a group of anchor bars on each corrugated surface. The two threaded steel bars on each group of anchor bars must also be welded to the waterstop steel plate.

[0014] S4. Wall pouring: While pouring the wall, the concrete is vibrated continuously. Every time a piece of the fold surface is poured, the concrete density is checked through the concrete density test holes on the fold surface until the pouring is completed.

[0015] S5. Subsequent construction: After the wall maintenance is completed, the subsequent construction is carried out. After the construction of the entire wall is completed, the protective layer of the corrugated steel plate at the construction joint is constructed.

[0016] The beneficial effects of the present invention are:

[0017] 1. The present invention adopts a sealing form in which a water-stop steel plate is welded to a corrugated steel plate in front and behind at the construction joint, leaving only a number of concrete density test holes with a diameter of only about 1 cm, and the concrete density test holes are blocked during the concrete pouring process, which can effectively avoid serious leakage of the construction joint structure during the construction process.

[0018] 2. The present invention is provided with a concrete density testing hole, which can check whether the concrete at different positions is dense at any time, and can effectively avoid the generation of concrete hollowing near the construction joint.

[0019] 3. In the present invention, the corrugated steel plate and the water-stop steel plate are connected by anchor bars, which effectively prevents the water-stop steel plate from tilting during the construction process.

[0020] 4. The present invention is provided with anchor bars and a folded surface with an obtuse opening, and a plurality of stripes are provided on the folded surface, which can enhance the lap joint strength of the walls on both sides of the construction joint. BRIEF DESCRIPTION OF THE DRAWINGS
