Description

Technical Field

[0001] The invention relates to the field of elevated ramp construction, and in particular to a high-strength steel pipe column supporting portal frame. Background Art

[0002] At present, with the continuous progress of society, more and more roads are being built in cities, especially the construction of additional roads within the scope of existing roads. The construction scope is limited, and the construction process needs to minimize the impact on the smoothness of existing roads. Therefore, temporary pillars need to be built to initially bear the steel box girders.

[0003] For example Figure 1 In the construction scenario shown, the elevated ramp needs to cross directly above the existing expressway, and driving roads are paved at the bottom of both sides of the elevated ramp. The existing construction of temporary pillars needs to be built directly on the driving road.

[0004] Regarding the above-mentioned related technologies, when it is necessary to ensure that the drivable lanes on the driving road are maximized, it is difficult to meet the requirement by directly building temporary pillars on the driving road through traditional means, so it is necessary to design a new temporary pillar. Summary of the invention

[0005] In order to meet the requirement of maximizing the drivable lanes on the road when setting up temporary pillars, the present application provides a high-strength steel pipe column supporting gantry.

[0006] The present application provides a high-strength steel pipe column supporting portal frame, which adopts the following technical solution:

[0007] A high-strength steel pipe column supporting portal frame includes a supporting frame for being erected on both sides of a travel road, a connecting frame erected on the top of the two supporting frames, and a receiving frame installed on the connecting frame. The top of the supporting frame and the connecting frame, as well as the bottom of the receiving frame and the connecting frame are detachably connected via a connecting assembly.

[0008] By adopting the above technical solution, support frames are first built on both sides of the driving road, and then connecting frames are erected on the top of the two support frames, and finally a receiving frame is built to complete the construction of temporary pillars. The steel pipe box can be lowered onto the receiving frame later, and the driving road can be open to traffic normally, thereby maximizing the drivable lanes on the driving road.

[0009] Preferably, the connecting frame comprises: a plurality of single frames and a first connecting rod, wherein the plurality of single frames are arranged in a horizontal direction at intervals between the supporting frame and the receiving frame, and the first connecting rod is simultaneously connected to each of the single frames.

[0010] By adopting the above technical solution, after the support frame is installed, a number of single frames are placed on two support frames at intervals along the length direction of the support frame, and then the single frames are connected by the first connecting rod; the above structure is easy to assemble and has high stability.

[0011] Preferably, the connecting assembly includes: a connecting screw and a connecting nut, the supporting frame or the receiving frame is connected to the connecting screw at the position corresponding to each single frame, and the connecting screw is passed through the connecting frame; the connecting nut is threadedly installed on the connecting nut.

[0012] By adopting the above technical solution, when placing each single frame, the connecting screw is passed through the connecting frame, and then the connecting nut is screwed into the connecting screw, so that the single frame and the supporting frame can be connected; and when building the receiving frame, the connecting screw is also passed through the connecting frame, and then the connecting nut is screwed into the connecting screw, so that the single frame and the receiving frame can be connected.

[0013] Preferably, the support frame includes: a pair of side frames, a plurality of second connecting rods and a pair of supporting rods, the two side frames are arranged opposite to each other, the plurality of second connecting rods are arranged between the two side frames, and the two ends of the second connecting rods are respectively fixedly installed on the two side frames; the supporting rods extend in the length direction of the side frames, the two supporting rods are respectively installed on the top of the two side frames, and the connecting screws are threadedly installed on the supporting rods.

[0014] By adopting the above technical solution, the overall structure is simple, the strength is high, and it is easy to transport.

[0015] Preferably, a plurality of reinforcing rods are arranged inside between the support frame and the connecting frame, the reinforcing rods are arranged obliquely, and two ends of the reinforcing rods are respectively connected to the support frame and the connecting frame.

[0016] By adopting the above technical solution, since the receiving frame is built on the connecting frame at a position corresponding to the position between the two supporting frames, the middle position of the connecting frame has a larger bearing capacity, and the overall bearing capacity is improved by arranging an inclined reinforcing rod.

[0017] Preferably, one end of the reinforcing rod is hinged to the connecting frame, and the other end is detachably mounted to the supporting frame by bolts.

[0018] By adopting the above technical solution, after the single frame is erected on the support frame, the reinforcing rod is rotated, and the other end of the reinforcing rod is fixedly installed on the support frame by bolts, thereby completing the installation of the reinforcing rod, and the installation efficiency is high.

[0019] Preferably, the bottom of the support frame is provided with embedded reinforcements along the length direction for being embedded in concrete.

[0020] By adopting the above technical solution, before building the support frame, a concrete base is first laid, and embedded reinforcement is embedded in the concrete base. Then, when the support frame is erected, the support frame and the embedded reinforcement are connected by welding to improve the overall stability.

[0021] Preferably, a plurality of buffer pads are provided on the top of the receiving frame.

[0022] By adopting the above technical solution, when the steel box girder is lowered onto the receiving frame, the buffer pad can play a buffering role and can also provide certain protection for the receiving frame.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. First build support frames on both sides of the driving road, then build connecting frames on the top of the two support frames, and finally build receiving frames to complete the construction of temporary pillars, so that the steel pipe box can be lowered to the receiving frames later, and the driving road can be opened to traffic normally, maximizing the drivable lanes on the driving road;

[0025] 2. Since the receiving frame is built on the connecting frame at a position between the two supporting frames, the middle position of the connecting frame has a larger bearing capacity. By setting an inclined reinforcing rod, the overall bearing capacity is improved. BRIEF DESCRIPTION OF THE DRAWINGS
