[0026] External wall formwork 10

[0027] During the construction of underground building structures, there are no openings in the exterior walls of the structures, and it is not possible to connect and install the scaffolding by setting wall attachments at the openings. Therefore, it is necessary to install a connecting device on the exterior wall, and achieve a rigid connection between the scaffolding and the exterior wall of the structure by welding the wall connecting rods to the connecting plates of the connecting device. The exterior wall connecting device is composed of a connecting plate and anchor bars. The connecting device is pre-buried during the process of binding the wall reinforcement. The anchor bars of such connecting plates have no waterproof structure. When the groundwater level is high and the waterproofing coil leaks, the groundwater will enter the exterior wall from the anchor bar position, causing indoor leakage. In order to solve the above problems, the utility model provides a scaffolding pre-buried connection device

[0028] Figure 1 and Figure 2 The present invention shows a scaffolding pre-embedded connection device according to an embodiment of the present invention. Specifically, the connection device comprises:

[0029] Connecting plate 1, connecting plate 1 is used to connect wall connecting rod 61, combined with Figure 7 As shown, one end of the wall connecting rod is vertically welded to one side of the connecting plate; the wall connecting rod 61 is used to connect the scaffolding 6, and the other end of the wall connecting rod is used to connect the scaffolding; the structure of the above-mentioned connecting plate can be rectangular, circular or other shapes, for example, the connecting plate is a square structure with a side length of 30 cm.

[0030] The first end of the connecting column 2 is vertically welded to one side of the connecting plate 1; the length of the connecting column should be less than the thickness of the structural outer wall, so as to facilitate the scaffolding embedded connection device to be set in the structural outer wall. In a preferred embodiment, the connecting column is a steel bar with a diameter of 1 cm.

[0031] The water stop plate 3 includes a baffle plate 31 and a side plate 32. The baffle plate 31 is a rectangular structure, and the side plate 32 is a trapezoidal structure. The side plates 32 are respectively connected to one side of the baffle plate 31, and the adjacent side plates 32 are welded and connected. The side plates 32 are inclined toward the connecting plate 1, and the baffle plate and the side plates form a bell-mouth structure. Due to the setting of the water stop plate, the water infiltrating inward through the connecting column is blocked by the water stop plate and will not continue to infiltrate inward, which can play an anti-seepage role.

[0032] Sealing sleeve 4, such as Figure 4As shown, the sealing sleeve 4 includes an annular substrate 41, an inner ring 42 and an outer ring 43, one side of the inner ring 42 is vertically connected to the inner ring of the substrate 41, and one side of the outer ring 43 is vertically connected to the outer ring of the substrate 41; the inner ring 42 of the sealing sleeve 4 is inserted into the connecting column 2; the substrate 41, the inner ring 42 and the outer ring 43 form an open expansion space, and the expansion space is filled with water-absorbing and expanding particles. In a preferred embodiment, the opening of the expansion space faces the connecting plate 1. Through such an orientation setting, the infiltrated water can contact the water-absorbing and expanding particles at the first time and stop the water at the first time. In a specific embodiment, at least the inner ring and the outer ring of the substrate 41, the inner ring 42 and the outer ring 43 are made of flexible rubber materials; the above-mentioned water-absorbing and expanding particles can be water-absorbing resins, and the specific types of water-absorbing resins are disclosed in detail in the prior art. For example, the water-absorbing resin made by partial crosslinking or saponification of water-soluble resins, commonly used are starch-acrylonitrile graft polymers and starch-acrylic acid graft polymers of the starch class, cellulose-acrylonitrile graft polymers and carboxymethyl cellulose crosslinked products of the fiber class, polyvinyl alcohol crosslinked products and acrylonitrile-vinyl acetate copolymer saponification products of the polyvinyl alcohol class, polyvinyl salts and methyl methacrylate-vinyl acetate copolymer saponification products of acrylic acid class, polyvinyl alcohol and dipropylene glycol crosslinked products of polyalkylene ethers, and isobutylene-maleic anhydride alternating copolymers of maleic anhydride class, etc.

[0033] When external water infiltrates from the space around the connecting column, the water will come into contact with the water-absorbing and swelling particles. Due to the expansion of the water-absorbing and swelling particles, the water will squeeze the inner circle of the sealing sleeve inward and the outer circle of the sealing sleeve outward respectively. By squeezing the inner circle of the sealing sleeve inward, the inner circle of the sealing sleeve comes into contact with the connecting column and the tiny gap between the sealing sleeve and the connecting column is eliminated, thereby eliminating the gap between the sealing sleeve and the connecting column; by squeezing the outer circle of the sealing sleeve outward, the outer circle of the sealing sleeve comes into contact with the building structure (concrete) and the tiny gap between the sealing sleeve and the concrete is eliminated, thereby eliminating the gap between the sealing sleeve and the concrete, thereby preventing water from infiltrating into the interior of the building structure through the tiny gaps around the connecting column.

[0034] In a specific embodiment, the connecting plate 1 is a rectangular structure, the number of connecting columns 2 is four, and the connecting columns 2 are arranged in a rectangular shape, such as Figure 1 and Figure 2 As shown, the connecting columns are respectively arranged at the four top corners of the connecting plate; of course, the connecting columns can also be arranged at intervals in other ways; corresponding to the number of connecting columns, the number of sealing sleeves 4 is four, and the sealing sleeves 4 are respectively inserted into the corresponding connecting columns 2. Of course, other numbers of connecting columns can also be set according to the force requirements of the connecting plate and the water stop plate (considering the performance parameters such as the diameter and material of the connecting column).

[0035] The inventors found that the sealing sleeve of the above structure includes an open expansion space formed by a substrate 41, an inner ring 42 and an outer ring 43, and the expansion space is filled with water-absorbing expansion particles. Due to the presence of the opening, the water-absorbing expansion particles will move under the action of gravity, resulting in difficulty in directly filling enough water-absorbing expansion particles into the expansion space during the construction process. In a further preferred embodiment, the sealing sleeve 4 also includes a first annular baffle 44, which is vertically connected to the other side of the inner ring 42. The sealing sleeve 4 also includes a second annular baffle 45, which is vertically connected to the other side of the outer ring 43. By setting the first ring-mounted baffle and the second ring-mounted baffle, the opening of the expansion space is reduced, and the water-absorbing expansion particles can be filled more conveniently.

[0036] Combination Figure 6 and Figure 7 As shown, the specific application of the scaffolding pre-buried connection device of the utility model is described. Figure 6 The embedded process of the scaffolding connection device in the structure exterior wall is shown. Figure 7 The scaffold is shown to be connected to the connecting plate via a wall connecting rod. Specifically, the connecting column 2 is connected to the external wall vertical steel bars 8 inside the external wall 5 of the building structure via additional steel bars 7 arranged in the horizontal direction.
