Description

Technical Field

[0001] The utility model belongs to the technical field of hanging formwork in the construction industry, and in particular relates to a construction hanging formwork structure. Background Art

[0002] During the construction process, when processing the drainage pipe area, a hanging mold tool will be used to support the drainage pipe area. After the subsequent drainage pipe installation is completed, the drainage pipe area needs to be poured for the second time. During the construction process, a hanging mold bracket is needed to support the opening area. The current traditional hanging mold tools are composed of wooden boards, wooden strips and iron wires. During construction, the lower side of the wooden board is supported by wooden strips. Holes corresponding to the drainage pipes are opened on the wooden board. Then, the wooden strips are pulled from the upper side with iron wires, and finally the opening area is poured for the second time. However, the operation steps of this type of hanging mold tool are cumbersome, and the iron wire needs to be cut after pouring. The removal of the lower wooden board is also difficult, and the wooden board will be damaged during removal, making it impossible to reuse the hanging mold tool. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-3 As shown, a construction hanging formwork structure of the utility model comprises two groups of symmetrically arranged plastic support plates 1 and semicircular sleeves 11. Before installation, the plastic support plates 1 must be coated with a concrete release agent on their upper sides to facilitate subsequent disassembly of the plastic support plates 1. The semicircular sleeves 11 are fixedly arranged at the lower ends of the plastic support plates 1. An angle brace 16 is arranged between the plastic support plates 1 and the semicircular sleeves 11 on the same side. The angle brace 16 can enhance the strength between the plastic support plates 1 and the semicircular sleeves 11. The lower ends of the two plastic support plates 1 are fixedly provided with support bars 17, which can improve the support of the plastic support plates 1 The plastic support plate 1 is provided with a notch 12 matching with the semicircular sleeve 11. The prefabricated notch 12 and the semicircular sleeve 11 can match with the caliber of the drainage pipe to be constructed, so that the two semicircular sleeves 11 can be sleeved on the installed drainage pipe. A side of one plastic support plate 1 is provided with an embedding groove 13, and a side of the other plastic support plate 1 is provided with an embedding block 14 matching with the embedding groove 13. The embedding of the embedding groove 13 and the embedding block 14 can enhance the sealing between the two plastic support plates 1. The two semicircular sleeves 11 form a circular sleeve, and a fixing component is provided between the two semicircular sleeves 11;

[0026] like Figure 4-6 As shown, the fixing assembly includes a base 15, and the bases 15 are fixedly provided on both sides of the two semicircular sleeves 11 near one end. A horizontal groove 151 is opened at the end of the base 15 away from the semicircular sleeve 11. An extension bolt 152 is hingedly provided in one of the horizontal grooves 151 of the two adjacent bases 15. The extension bolt 152 can be rotatably assembled inside the two adjacent horizontal grooves 151. When the extension bolt 152 is assembled inside the two horizontal grooves 151, the two plastic support plates 1 can be in the same horizontal state. The other end of the extension bolt 152 is threadedly connected with an ear nut 153. By rotating the ear nut 153, the semicircular sleeves 11 on both sides can be fixed, so that the plastic support plate 1 is fixedly assembled on the drain pipe. The horizontal groove 151 is matched with the extension bolt 152. No thread is set in the middle of the extension bolt 152, and a thread is set on the side of the extension bolt 152 away from the hinge.

[0027] A top support assembly is provided between the plastic support plate 1 and the semicircular sleeve 11 on the same side, and the top support assembly includes a top support frame 21. The top support frame 21 is fixedly provided at one end of the two semicircular sleeves 11 away from each other, and an oblique support 24 is fixedly provided between the top support frame 21 and the semicircular sleeve 11. A plurality of top support bolts 22 are fixedly provided at the upper end of the top support frame 21. The top support bolts 22 are threadedly connected with threaded sleeves 23. The outer side of the threaded sleeve 23 is provided with anti-slip patterns, and the support bar 17 matches the position of the plurality of threaded sleeves 23.

[0028] Working principle: when pouring concrete around the drain pipe, first buckle the two semicircular sleeves 11 on the drain pipe, and at the same time, make the embedding groove 13 between the two plastic support plates 1 engage with the embedding block 14, and then rotate the lengthening bolts 152 in the bases 15 on both sides respectively, so that the lengthening bolts 152 enter the two adjacent horizontal grooves 151. At this time, the horizontality of the two plastic support plates 1 can be adjusted by the lengthening bolts 152, so that the two plastic support plates 1 approach the same horizontal plane, and then push the two semicircular sleeves 11 and the plastic support plate 1 upward to make the upper end of the plastic support plate 1 close to the concrete wall, and then rotate the ear nuts 153 on one side of the two lengthening bolts 152 respectively, so that the ear nuts 153 are close to the side of the base 15, so that the lengthening bolts 152 are fixed inside the two adjacent horizontal grooves 151, and at the same time, the two semicircular sleeves 11 can be brought close to each other, so that the semicircular sleeves 11 and the plastic support plate 1 are fixed on the drain pipe;

[0029] After the plastic support plate 1 and the semicircular sleeve 11 are fixedly installed, several threaded sleeves 23 are rotated respectively so that the threaded sleeves 23 can move upward until they are pressed against the plastic support plate 1, so that the threaded sleeves 23 and the top support bolts 22 have an upward and downward expansion tendency for the plastic support plate 1 and the top support frame 21 respectively. Therefore, relying on the toughness of the plastic support plate 1 made of plastic material, the threaded sleeves 23 push the plastic support plate 1 upward to fit closely to the concrete wall, thereby enhancing the sealing between the plastic support plate 1 and the concrete wall and preventing concrete leakage during concrete pouring.

[0030] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
