Problems solved by technology

These two methods are both costly in materials (11 dowel bars need to be installed in a single frame, which will not be measured in foreign constructions), and the installation speed is relatively slow, which brings great inconvenience to the construction
It is difficult to meet the needs of fast and efficient dowel bar installation

Embodiment 1

[0032] Such as figure 1 and figure 2As shown, the embodiment of the present application provides a portable concrete pavement dowel installer, which is used to squeeze eleven dowel bars 300 arranged at intervals along the width direction of the surface of the concrete pavement 200 into the concrete pavement 200 . The portable dowel installer for concrete pavement includes two support bases 100, a support plate 110 and a pressure plate 120, the two ends of the support plate 110 straddle the width direction of the concrete road surface 200 and are respectively connected with the two support bases 100, the pressure plate 120 Located on the top of the support plate 110, the support plate 110 is connected with a lift assembly for driving the pressure plate 120 up and down. The lift assembly is two lift cylinders 160 respectively connected to both ends of the support plate 110. The cylinder rods of the two lift cylinders 160 are vertical Arranged and respectively communicated with...

Embodiment 2

[0038] Such as image 3 and Figure 4 As shown, the structure of the portable concrete pavement dowel installer provided in this embodiment is roughly the same as the portable concrete pavement dowel installer provided in Embodiment 1. The difference is that in this embodiment, the pressing plate 120 is sleeved There are eleven sleeves 170 that can move along it, each sleeve 170 is provided with a pair of pressure rod grooves 130 on both sides, the bottom of each pressure rod groove 130 runs through the bottom end of the pressure plate 120, eleven pairs of pressure rods The rod grooves 130 correspond to the eleven dowel rods 300 one by one, and each rod groove 130 is provided with a pressure rod 140, and the bottoms of the pressure rods 140 in each pair of pressure rod grooves 130 press the corresponding force transmission rods respectively. both ends of the rod 300.

[0039] The portable concrete pavement dowel installer provided in this embodiment can facilitate the staff ...

Abstract

The invention discloses a portable concrete pavement dowel bar mounting device and a dowel bar mounting method, and relates to the field of pavement construction. The portable concrete pavement dowelbar mounting device comprises two supporting seats, a supporting plate and a pressing plate, and the two ends of the supporting plate stretch across the width direction of the concrete pavement and are connected with the two supporting seats correspondingly. The pressing plate is arranged over the supporting plate; the supporting plate is connected with a lifting assembly used for driving the pressing plate to ascend and descend. Pairs of pressing rod grooves which extend in the height direction of the pressing plate and are oppositely formed are formed at the two sides of the pressing platerespectively, the bottom of each pressing rod groove penetrates through the bottom end of the pressing plate, the multiple pairs of pressing rod grooves correspond to the multiple dowel bars one to one, a pressing rod is arranged in each pressing rod groove, and the bottoms of the pressing rods in each pair of pressing rod grooves abut against the two ends of the corresponding dowel bars respectively. According to the portable concrete pavement dowel bar mounting device and the dowel bar mounting method, the dowel bars can be rapidly and efficiently installed, and the beneficial effects that the construction speed is high, the construction cost is saved, and the construction period is shortened are achieved.

Description

technical field [0001] The present application relates to the field of road construction, in particular to a portable concrete road dowel installer and a dowel installation method. Background technique [0002] The concrete pavement designed in Europe, the United States, and Africa under extreme weather conditions is different from the domestic concrete pavement design. The domestic concrete pavement design generally only designs dowel bars for pavement concrete when the concrete pavement joint (or a section of construction ends) The temperature is stretched and stretched, but the situation in foreign countries is different. Many countries often adopt the American standard to set up concrete pavement dowels for each block. Taking foreign construction teams as an example, when they were working in the Erta Ale Volcanic Area in Ethiopia, Africa, which is known as the "Gate of Hell", the site was hot and hot all the year round, and the temperature in summer reached more than 50...
