[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Referring to Figures 1-6 , the present utility model discloses a sunken wading room arc-shaped suspended formwork reinforcement structure, which includes a plurality of corner arc-shaped aluminum forms 2. An arc-shaped aluminum form 1 is fixedly connected between two adjacent corner arc-shaped aluminum forms 2. Angle steels 3 are arranged on the top surfaces of two opposite arc-shaped aluminum forms 1. One end of the angle steel 3 is detachably connected to an outer aluminum form 9. A structural drop panel 4 is detachably connected to the bottom surfaces of two opposite arc-shaped aluminum forms 1. A top plate aluminum form 10 is installed at one end of the structural drop panel 4 away from the arc-shaped aluminum form 1. The end of the angle steel 3 away from the outer aluminum form 9 is detachably connected to the top plate aluminum form 10.

[0026] In the present utility model, the angle steel 3 is connected to the arc-shaped aluminum form 1 to form a formwork at the high-low span part. After concrete pouring, it can be formed in one time, eliminating subsequent manual coating and other processes; it can also effectively avoid problems such as formwork displacement and corner chipping during form removal, effectively improving the project quality and progress, and reducing the comprehensive cost.

[0027] As a further optimized solution, a plurality of corner arc-shaped aluminum forms 2 and a plurality of arc-shaped aluminum forms 1 are spliced into a rectangle.

[0028] As a further optimized solution, a plurality of angle steels 3 are provided.

[0029] As a further optimized solution, both ends of the angle steel 3 are respectively detachably connected to the outer aluminum form 9 and the top plate aluminum form 10 through through bolts 8. The through bolts 8 adopt water-stop screws or sleeve through bolts. The water-stop screws need to be cut flat, and the sleeve through bolts need to be blocked later.

[0030] As a further optimized solution, the sides of the arc-shaped aluminum form 1 and the corner arc-shaped aluminum form 2 in contact with the structural drop panel 4 are arc-shaped. The subsequent leveling layer is eliminated, and it can be formed in one time.

[0031] As a further optimized solution, the arc-shaped aluminum form 1 is detachably connected to the angle steel 3 through a plurality of connectors 7.

[0032] As a further optimized solution, the arc-shaped aluminum form 1 and the corner arc-shaped aluminum form 2 are hollow inside. It can reduce the weight of the arc-shaped aluminum form 1 and the corner arc-shaped aluminum form 2.

[0033] For a further optimized solution, a cavity is provided on the top surface of the arc-shaped aluminum formwork 1, and the connecting member 7 is pre-set in the cavity. The connecting member 7 can be a bolt or a pin.

[0034] Working process:

[0035] I. Processing and manufacturing of the circular arc formwork: First, match the formwork according to the dimensions of each side of the sunken room. Generally, each side is connected by a whole arc-shaped aluminum formwork 1 and a corner arc-shaped aluminum formwork 2. When it is relatively long, each side of the arc-shaped aluminum formwork 1 can be divided into several sections for assembly; the corner part should be made into a finished corner arc-shaped aluminum formwork 2. It is necessary to cut a 45° bevel on the profile, and then weld the two profiles with the bevels facing each other at a 90° vertical angle to form the corner arc-shaped aluminum formwork 2. The corner arc-shaped aluminum formwork 2 is connected to the straight-edge arc-shaped aluminum formwork 1 on each side to form an overall circular arc formwork.

[0036] II. Binding of the top plate steel bars: Clean the sundries on the circular arc formwork, snap the steel bar spacing lines. The plate steel bars start to be bound from half of the spacing at the edge of the beam or shear wall 5. First, bind the bottom plate steel bars. After the pipeline installation, then bind the upper layer of steel bars on the flat plate.

[0037] III. Installation of the arc-shaped suspended formwork: One end of the angle steel 3 passing through the beam or shear wall 5 is fixed to the upper opening of the outer aluminum formwork 9 through the through bolts 8. One end of the angle steel 3 passing through the guide wall or the turned-up edge 6 is connected to the top plate aluminum formwork 10 of the structural drop panel 4 through the through bolts 8, forming a bridge system, which can effectively connect the arc-shaped suspended formwork according to the position and elevation. The corner part is installed with the corner arc-shaped aluminum formwork 2 (the size is determined according to the design) at the high-low span part to form a retaining formwork.

[0038] IV. Pouring of concrete: The virtual paving thickness of the concrete for pouring the plate should be greater than the plate thickness by 20 mm. The vibration spacing ≤ 500 mm, and vibrate densely in a plum blossom shape. First, scrape it with a ruler. The position at the root of the suspended formwork should be leveled, and the flatness should be well controlled. Perform secondary finishing and pressing to smooth it, eliminating the need for a later leveling layer and achieving one-time forming.

[0039] V. Removal of the formwork and forming effect: First, remove the angle steel 3 from one side to the other in sequence, and then remove the arc-shaped suspended formwork. Do not pry or smash it violently. The concrete circular arc should be smooth and dense.

[0040] VI. Treatment of the through bolts 8: The water-stop screw is cut flat with a cutting machine; the holes of the sleeve through bolts are sealed tightly with slightly expanded cement mortar.

[0041] VII. Curing: Sprinkle water on the floor slab regularly for curing to prevent problems such as sanding, cracking, and insufficient strength caused by water loss.

[0042] The arc aluminum formwork 1 and the corner arc aluminum formwork 2 of the present utility model are made of aluminum alloy profiles. According to the sizes of each bay, an arc-shaped suspended formwork is made. Angle steel 3 is used as a bridge reinforcement system to connect with the arc-shaped suspended formwork, and it is installed at the high-low span part to form a retaining formwork. After concrete pouring, an "octagon" is formed at one time, eliminating the subsequent processes such as manual plastering of the octagon.

[0043] The arc aluminum formwork 1 and the corner arc aluminum formwork 2 of the present utility model adopt standardized formwork. The position of the sunken floor slab is fixed accurately and firmly, and the root arc is formed at one time, saving the subsequent painting cost and eliminating the technological drawbacks of traditional formwork running and corner chipping during form removal.

[0044] The present utility model effectively improves the project quality and progress, and reduces the comprehensive cost.
