Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a reusable road construction joint shaping device. Background Art
[0002] A construction joint refers to the joint formed between the first and second concrete pours during the concrete pouring process, when the concrete is poured in sections due to design requirements or construction needs. During construction, for plain concrete structures, stress-bearing steel bars with a diameter of no less than 16mm should be embedded in the construction joints. The embedded depth and exposed length of the stress-bearing steel bars should not be less than 30d of the steel bar diameter, and the spacing should not exceed 20mm. In traditional road construction joint construction technology, cutting machines are usually used to cut the road to leave a gap. This practice often cuts the stress-bearing steel bars in the road construction joint, thus affecting the quality of the road. The cutting process also generates a lot of dust and noise, which has a significant impact on the surrounding environment and does not meet the requirements of green construction. Utility Model Content

[0006] Furthermore, the upper shaped steel template and the lower shaped steel template are provided with corresponding connection holes on the inner surfaces at both ends of the corresponding hollow interiors.
[0007] Furthermore, the detachable fastening assembly is a bolt fastening assembly; the bolt fastening assembly includes a bolt and a locking nut, and the bolt is locked by the locking nut after passing through the connecting hole.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] like Figures 1 to 5As shown, a reusable road construction joint shaping device includes an upper shaped steel template 1 and a lower shaped steel template 4; the cross-sections of the upper shaped steel template 1 and the lower shaped steel template 4 are both rectangular hollow structures; the upper surface of the upper shaped steel template 1 is provided with vertical lifting rings 2, and the lower surface is evenly provided with steel bar reserved holes 3; the side of the lower shaped steel template 4 is provided with lateral lifting ears 5; the vertical lifting rings 2 and the lateral lifting ears 5 can be fixed by welding or bolting; the upper shaped steel template 1 and the lower shaped steel template 4 are fixed at the positions of the corresponding hollow inner ends by detachable fastening components 6 to form a construction joint shaping device. When in use, the construction joint shaping device is installed and then set at the position of the road construction joint, the stressed steel bars are set in the steel bar reserved holes 3, and then the road concrete is poured on both sides of the construction joint shaping device. According to the characteristics and use requirements of the construction joint, suitable fillers are selected for filling. After the initial setting of the concrete is completed, the detachable fastening component 6 is removed, and then the vertical lifting ring 2 is lifted to take out the upper shaping steel template 1, and then the lower shaping steel template 4 is pulled out from the side through the lateral lifting ear 5 to complete the shaping of the construction joint. Since the construction joint shaping device consists of the upper shaping steel template 1 and the lower shaping steel template 4, The sides of the upper and lower shaped steel forms 1 and 4 are relatively flat, and the construction joint shaping device does not shift, ensuring the neatness of the construction joint. Therefore, the construction joint basically does not need to be trimmed to meet the construction process requirements. Even if there are some uneven areas due to lifting, they are small areas, and the workload and construction time of re-trimming are greatly reduced. In addition, there is no need to use a cutting machine to cut the road with a gap later. This not only avoids the problem of the cutting machine cutting the construction joint and causing the stressed steel bars to be cut, thereby affecting the quality of the road, but also avoids the problem of large dust and noise generated during the cutting process, which has a significant impact on the surrounding environment. The overall construction quality is good, the cycle is short, and the labor intensity is greatly reduced. At the same time, the construction joint shaping device can be reused after disassembly and assembly, which greatly reduces construction costs and meets the requirements of green construction.
[0020] As a preferred embodiment, the upper profiled steel template 1 and the lower profiled steel template 4 are provided with corresponding connection holes 7 on the inner surfaces at both ends of the corresponding hollow interiors.
[0021] In a preferred embodiment, the removable fastening assembly 6 is a bolt fastening assembly; the bolt fastening assembly includes a bolt and a locking nut, which is tightened by the locking nut after passing through the connection hole 7. The removable fastening assembly 6 is a pin fastening assembly; the pin fastening assembly includes a pin and a locking pin, which is tightened by the locking pin after passing through the connection hole 7. The appropriate removable fastening assembly 6 can be selected for installation and use based on the construction environment and project. Discarded bolts or pins at the construction site can also be used to reduce material costs.
[0022] As a preferred embodiment, Figure 5 As shown, two or more construction joint shaping devices of the same height and width are arranged side by side to form a large-scale construction joint shaping device. The basic size of the construction joint shaping device can be determined based on common construction joint widths. For example, common road construction joint widths are 10mm, 20mm, and 30mm. By setting a single construction joint shaping device to the basic width of 10mm, the construction requirements of most road construction joints can be met.
[0023] As a preferred embodiment, two or more construction joint shaping devices of the same height but different widths are arranged side by side to form a large-scale construction joint shaping device. For road construction joints with widths of 15mm or 25mm, one or two 10mm-wide construction joint shaping devices can be used in conjunction with a 5mm-wide construction joint shaping device to meet the corresponding construction joint width requirements.
[0024] Although the above describes and illustrates the specific implementation methods of the present invention in detail, it should be pointed out that: we can make various equivalent changes and modifications to the above implementation methods based on the concept of the present invention, and the functional effects produced therefrom still do not exceed the spirit covered by the specification, and should all be within the scope of protection of the present invention.
