Description

Technical Field

[0001] The utility model belongs to the technical field of road construction, and in particular relates to a road construction section connection device. Background Art

[0002] "Road" refers to highways, urban roads and places under the jurisdiction of units but where social motor vehicles are allowed to pass, including squares, public parking lots and other places for public access. Road construction sections include cross sections and longitudinal sections. The longitudinal section is a vertical section cut along the center line of the road. Since the road is long as a whole, it needs to be constructed in sections, which will produce road sections. The road section needs to use a section connection device to improve the stability of the connection between the new and old concrete in the section, thereby improving the quality of road construction.

[0003] Existing concrete road construction sections usually use pre-buried threaded rods to connect new and old roads. Since threaded steel mainly relies on friction to hold the road together, the inconsistent deformation of concrete and threaded rods due to the expansion and contraction of the road under different temperature environments may cause the tension to weaken, thereby causing expansion cracks and reflection cracks, which in turn affects the service life of the road. Utility Model Content

[0004] The utility model provides a road construction section connection device, which aims to solve the problem that the existing concrete road construction section construction usually adopts embedded threaded rods to connect the new and old roads. Since the threaded steel mainly relies on friction to pull the road, the expansion and contraction of the road under different temperature environments may cause the tension to weaken, thereby generating expansion cracks and reflection cracks, which further affects the quality of road construction.

[0006] Preferably, a dovetail block is fixedly provided at one end of the transverse partition, and a dovetail groove is provided at the other end of the transverse partition. The internal dimensions of the dovetail groove are matched with the external dimensions of the dovetail block, thereby improving the convenience of extending the transverse partition.

[0007] Preferably, the transverse partition is made of cast iron, and two groups of grooves are symmetrically provided on the surface of the transverse partition, thereby increasing the contact area between the transverse partition and the road surface.

[0008] Preferably, the second connecting rod and the block are both made of cast iron and fixedly connected to form an integrated structure. A threaded groove is provided on the outer surface of the second connecting rod close to the block, thereby increasing the tension of the connection between the second connecting rod and the concrete road.

[0009] Preferably, the connecting rod 2 and the limiting block are both cylindrical, and the external dimensions of the connecting rod 2 and the limiting block are respectively adapted to the internal dimensions of the notch 1 and the notch 2, thereby improving the stability of the connection between the connecting rod 1 and the connecting rod 2.

[0010] Preferably, a card slot is opened on the inner side wall of the notch one, and a sealing ring is clamped inside the card slot. The sealing ring is made of silicone rubber and is in a circular ring shape.

[0020] See also Figure 1-4The utility model provides an embodiment: a road construction section connection device, including a diaphragm 1, a connecting rod 1 2 and a connecting rod 2 3. The diaphragm 1 is made of cast iron. Two groups of grooves 15 are symmetrically opened on the surface of the diaphragm 1, which increases the contact area between the diaphragm 1 and the road surface, while reducing the dead weight of the diaphragm 1 to save materials. The diaphragm 1 is in a long strip shape and can be used as a template to limit the flow of concrete during concrete road pouring, thereby reducing the amount of work for installing and disassembling the template. The template is a plate used to limit the flow of concrete. The template is a prior art and will not be repeated here. The side wall of the diaphragm 1 is provided with a plurality of notches 3 12 for the connection rod 2 to be inserted. The connection rod 2 is in the shape of a round rod and is adapted to the internal size of the notch 3 12, so as to facilitate the connection of the connection rod 2. The connection rod 2 is inserted into the notch 3 12 and then welded to improve the stability of the connection between the diaphragm 1 and the connection rod 2. Both ends of the connection rod 2 are provided with notches 6 for the connection rod 2 3 to be inserted. The interior of the connection rod 2 is provided with two notches 2 7 which are connected with the notch 6 in sequence. A spring 9 is fixedly provided on the inner wall of the notch 2 7 by welding, and the other end of the spring 9 is fixedly provided with a spring 9 by welding. The limit block 10 and the other end of the limit block 10 are fixedly connected to the connecting rod 2 3 by welding. The connecting rod 2 3 and the limit block 10 are both cylindrical. The external dimensions of the connecting rod 2 3 and the limit block 10 are adapted to the internal dimensions of the slot 1 6 and the slot 2 7 in turn, so that the connecting rod 2 3 and the limit block 10 can slide horizontally in the slot 1 6 and the slot 2 7 in turn, thereby improving the stability of the connection between the connecting rod 2 and the connecting rod 2 3. The other end of the connecting rod 2 3 passes through the slot 1 6 and is fixedly provided with a stop block 4. The connecting rod 2 3 and the stop block 4 are both made of cast iron and fixedly connected. An integrated structure, a threaded groove 5 is provided on the outer surface of the connecting rod 2 3 near the block 4. When the connecting rod 2 3 and the block 4 are cast on the concrete pavement, the tension of the connection between the connecting rod 2 3 and the concrete road is improved. When the concrete road expands and contracts, the length of the connecting rod 1 2 inserted in the slot 2 7 can be changed through the expansion and contraction of the spring 9, so that the connecting rod 1 2 and the connecting rod 2 3 can be expanded and contracted synchronously with the concrete pavement, thereby reducing the stress difference, thereby improving the stability of the connection between the connecting rod 1 2, the connecting rod 2 3 and the block 4 and the concrete section, thereby extending the service life of the road.

[0021] A dovetail block 13 is fixedly provided at one end of the diaphragm 1, and a dovetail groove 14 is opened at the other end of the diaphragm 1. The internal dimensions of the dovetail groove 14 are adapted to the external dimensions of the dovetail block 13. The dovetail block 13 is clamped inside the dovetail groove 14, which improves the convenience of connecting the diaphragm 1, thereby facilitating the connection construction of road sections of different sizes.

[0022] A card slot 8 is provided on the inner wall of the notch 1 6 , and a sealing ring 11 is clamped inside the card slot 8 . The sealing ring 11 is made of silicone rubber and is in a circular ring shape. The sealing ring 11 is sequentially sleeved on the outer surface of the connecting rod 2 3 , thereby improving the sealing performance of the connection between the connecting rod 2 3 and the connecting rod 1 2 .

[0023] Working principle: When using this road construction section connection device, the operator first places the diaphragm 1 vertically on the road section, so that the diaphragm 1 is perpendicular to the longitudinal direction of the road centerline. Two groups of grooves 15 are symmetrically opened on the surface of the diaphragm 1, which increases the contact area between the diaphragm 1 and the road surface, while reducing the weight of the diaphragm 1 and saving materials. The dovetail block 13 is clamped inside the dovetail groove 14, and the diaphragm 1 can be extended to adapt to the construction of road sections of different sizes. The diaphragm 1 is used to enclose the road section. When pouring concrete, the diaphragm 1 can limit the flow of concrete, thereby reducing the installation and disassembly of the template at the road section. The device is symmetrically distributed. When the device is completely cast in the road, the diaphragm 1, connecting rod 1 2, connecting rod 2 3 and block 4 are jointly stressed to pull the two ends of the road together, thereby improving the stability of the section connection. When the temperature changes and causes the concrete road to expand and contract, the length of the connecting rod 1 2 inserted in the slot 2 7 can be changed through the expansion and contraction of the spring 9, so that the connecting rod 1 2 and the connecting rod 2 3 can be synchronously expanded and contracted with the concrete pavement, thereby reducing the stress difference, thereby improving the stability of the connection between the connecting rod 1 2, the connecting rod 2 3 and the block 4 and the concrete section, thereby extending the service life of the road.
