Description

Technical Field

[0001] The present application relates to the technical field of prefabricated beams, and in particular to a prefabricated beam wet joint hanging formwork structure. Background Art

[0002] Wet joints refer to the joints in which prestressed concrete beams are prefabricated in blocks, cantilevered and assembled into large-span continuous beams, and the beam parts are connected into a whole using cast-in-place concrete.

[0003] In existing construction, when pouring wet joints, it is necessary to set up a support frame under the beam body to support the bottom formwork for subsequent pouring. When this structure is actually used, it is time-consuming and labor-intensive to set up the support frame, which reduces the efficiency of on-site construction. At the same time, after the support frame is set up, the bottom of the beam body is impassable, which is very inconvenient. Utility Model Content

[0004] Based on this, it is necessary to provide a prefabricated beam wet joint hanging formwork structure to overcome the defects mentioned in the above background technology.

[0034] Example

[0035] This embodiment provides a prefabricated beam wet joint hanging formwork structure, such as Figure 1 As shown, it includes a bracket 1, a bottom mold assembly 2, a suspension rod assembly 3 and a suspension rope 4, wherein the bracket 1 and the bottom mold assembly 2 are arranged on the upper and lower sides of the wet joint from top to bottom and extend along the axial direction of the wet joint, and the ends of the above two are respectively connected to the precast beams on both sides of the wet joint; the suspension rod assembly 3 is arranged between the bracket 1 and the bottom mold assembly 2, and its two ends are detachably connected to the bracket 1 and the bottom mold assembly 2, connecting the bracket 1 and the bottom mold assembly 2 as a whole, so that the bracket 1 and the bottom mold assembly 2 are tightly connected to the precast beam; one end of the suspension rope 4 is connected to the bottom mold assembly 2, and the other end thereof passes through the suspension rod assembly 3 and is connected to the bracket 1.

[0036] In this embodiment, the bracket 1 is a gantry frame, and there is a spacing distance between the part directly above the wet joint and the wet joint to facilitate finishing after the wet joint is poured; a gasket 5 is provided at the connection between it and the hanger assembly 3 to enhance the connection performance between it and the hanger assembly 3.

[0037] like Figure 2 As shown, the bottom mold assembly 2 includes a bottom mold plate 21 and square timber 22. The bottom mold plate 21 is arranged along the axial direction of the joint, and its top is abutted against the precast beam. It is provided with at least two first through holes for accommodating the suspension rod assembly 3 to pass through. The square timber 22 is arranged in a grid shape below the bottom mold plate 21 and abutted against it. A square timber 22 is provided below each first through hole, and a second through hole is provided at the position of the square timber 22 corresponding to the first through hole.

[0038] like Figure 3 As shown, a groove is provided at the connection between the bottom template 21 and the precast beam, and a pad 23 is provided in the groove. The pad 23 is elastic and its thickness is greater than the thickness of the groove. The pad 23 can strengthen the fit between the lower template and the precast beam to prevent leakage during concrete pouring.

[0039] like Figure 4 As shown, the suspension rod assembly 3 includes a screw rod 31 and a sleeve 32. The upper end of the screw rod 31 passes through the gasket 5 and the bracket 1 in sequence and is connected to the nut, and the lower end passes through the first through hole and the second through hole in sequence and is connected to the nut, so that the bracket 1 and the bottom mold assembly 2 are firmly fixed on both sides of the prefabricated beam; the sleeve 32 is sleeved on the outside of the screw rod 31, and the bottom thereof abuts against the top of the bottom mold plate 21, so as to facilitate the later removal of the suspension mold structure.

[0040] In this embodiment, the length of the sleeve 32 should be greater than the thickness of the joint to prevent the concrete from entering the sleeve 32 during pouring and affecting the subsequent demoulding.

[0041] The hanging formwork structure of the utility model does not need to set up a support frame when in use, which saves the time for setting up and dismantling the support frame and improves construction efficiency. At the same time, since there is no need to set up a support frame under the beam body, it will not hinder the passage of equipment under the beam body. When dismantling, the bottom formwork assembly 2 can be slowly placed on the ground through the lifting rope 4, which can avoid damage to the bottom formwork assembly 2 caused by falling from a high altitude and improve safety.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
