Technical Field

[0001] The utility model relates to the field of concrete formwork reinforcement, in particular to a structural beam outer side formwork reinforcement device. Background Art

[0002] The reinforcement of the outer formwork of concrete structural beams has always been a difficult problem to solve. In the early days, the outer formwork of smaller concrete structural beams was generally reinforced with iron wire, but the reinforcement stability was poor, and the outer formwork was not straight after reinforcement, resulting in poor structural appearance quality; for concrete structural beams with larger cross-sections, steel pipe scaffolding is generally used for reinforcement, which is labor-intensive and has a high difficulty coefficient; through summary and optimization during the construction process, the purpose of reinforcing the outer beam formwork is achieved by using tension bolts to reliably connect with the device fixed on the top plate formwork. Utility Model Content

[0003] The utility model aims to overcome the drawbacks of the current reinforcement of the outer template of the structural beam and provide an outer template reinforcement device which is simple to operate and has high construction efficiency.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is an outer template reinforcement device, including two fixing parts, the bottoms of the two fixing parts are connected by a connecting part, and the inner sides of the fixing parts are provided with semicircular grooves; when the two fixing parts are folded together, the semicircular grooves of the two fixing parts can be combined together to form a cylinder, and the interior of the cylinder is provided with an internal thread; a plurality of fixed installation holes are provided on the outer sides of the fixing parts.

[0005] Preferably, when the two fixing members are folded together, the cylinder formed by the semicircular grooves of the two fixing members is threadedly connected to one end of the tension bolt.

[0006] Preferably, when the two fixing members are folded together, nails or screws are installed in the fixing holes of the two fixing members.

[0007] Preferably, the two fixings are folded together and threadedly connected to one end of the tension bolt, and then fixed to the top plate formwork by nails or screws, and the other end of the tension bolt is fixed to the outer formwork of the structural beam by a nut.

[0008] Preferably, the connecting piece is made of flexible material.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the outer formwork reinforcement device of the utility model can be used to quickly complete the reinforcement of the outer formwork of the structural beam, ensure the appearance quality of the concrete structure, and is simple to operate and convenient to construct.

DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with specific embodiments, but the protection scope of the present invention is not limited thereto.

[0016] Example 1

[0017] like Figure 1-4 As shown, an outer template reinforcement device includes two fixing members 1, the bottoms of the two fixing members 1 are connected by a connecting member 2 made of flexible material, and a semicircular groove 6 is opened on the inner side of the fixing member 1; when the two fixing members are folded together, the semicircular grooves 6 of the two fixing members are combined to form a cylinder 15, and the interior of the cylinder 15 is provided with an internal thread 3; a plurality of fixing installation holes 4 are opened on the outer side of the fixing member 1.

[0018] When the two fixing members are folded together, the cylinder formed by the semicircular grooves of the two fixing members is threadedly connected to one end of the tension bolt 11 .

[0019] When the two fixing members are folded together, iron nails 8 are installed in the fixing holes 4 of the two fixing members.

[0020] After the two fixings are folded together and threadedly connected to one end of the tension bolt 11 , they are fixed to the top plate formwork through the iron nail 8 , and the other end of the tension bolt 11 is fixed to the outer side formwork 5 of the structural beam through the nut 10 .

[0021] The method of using this embodiment is as follows: after the outer formwork 5 of the beam is installed, install the square wood 9 and the steel pipe 13, pass the tension bolt 11 with the butterfly clip 12 through the reserved hole of the outer formwork 5 of the structural beam to the top plate formwork 7 on the other side, and pass through the gap between the two connectors, fold and press the device, and fix it with the tension bolt on the top plate formwork 7, and check that it is not loose. Tighten the nut 10 on the outside of the outer formwork of the structural beam to reinforce the formwork, and balance the pressure of the opposite side formwork of pouring concrete through the tension bolt and the device.

[0022] The outer formwork reinforcement device of this embodiment can be used in conjunction with the tension bolts to quickly complete the reinforcement of the outer formwork of the structural beam, and the construction operation is simple and convenient, which improves the construction efficiency, ensures the project quality, and reduces the construction cost, thereby greatly improving the cost expenditure and construction period.
