Technical Field

The invention relates to the technical field of steel structure support, in particular to a steel structure support structure.

Background

When a tunnel is excavated, a supporting and excavating method is usually adopted, an arch frame is adopted for a support in the prior art, the arch frame needs to be manufactured according to the excavation condition of the tunnel, the arch degree of the arch frame is determined, otherwise, a gap exists between the arch frame and the inner wall of the tunnel, so that the support is easy to be unstable, the arch frame is manufactured on site, the construction speed is slow, and the construction period is easy to delay.

Disclosure of Invention

The invention aims to solve the defects in the prior art and provides a steel structure supporting structure.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a steel structure supporting structure, includes the arch board, the arch board supports fixedly through the support column of two vertical settings arch board top both sides all rotate and connect the arc, are equipped with the hole of stepping down on the arch board support column one side articulated first jack, the flexible end of first jack from stepping down downthehole pass and with the arc is articulated fixed arch board upside center department is equipped with the centre bore, arch board downside center department is equipped with the support, is equipped with the second jack on the support, the flexible end of second jack passes from the centre bore, at the flexible fixed connection roof that serves of second jack.

Preferably, the upper surface of the top plate is an arc-shaped surface.

Preferably, the support comprises a base plate, and the second jack is fixed on the upper side of the base plate.

Preferably, the two sides above the base plate are supported and connected with the arched plate through two upright posts.

Preferably, the two ends of the arch plate are respectively fixedly connected with the mounting plate.

Preferably, first openings are symmetrically arranged on the arch plate, second openings are arranged on the arch plate, and the first openings and the second openings are arranged in a one-to-one correspondence mode.

The invention has the advantages that: the steel structure supporting structure provided by the invention is used for tunnel construction, and is mainly used for supporting a tunnel during tunnel excavation, the supporting structure is high in applicability, the support can be adjusted along with the arch degree excavated in the tunnel during tunnel excavation, and the steel structure supporting structure provided by the invention and the tunnel are fixed into a whole through rivets, so that the supporting stability can be further improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

As shown in fig. 1-3, the steel structure supporting structure provided by the invention comprises a cambered plate 1, wherein two ends of the cambered plate 1 are respectively fixedly connected with a mounting plate 14, and the cambered plate 1 is conveniently fixed on the ground of a tunnel through the mounting plates 14. Arch plate 1 supports fixedly through the support column 4 of two vertical settings the equal fixed connection riser 31 in 1 top both sides of arch plate, the articulated arc 3 in riser 31 one side is equipped with the hole of stepping down 11 on arch plate 1 support column 4 one side is through the articulated first jack 6 of first articulated seat 61, and the flexible end of first jack 6 passes from the hole of stepping down 11, the flexible end of first jack 6 pass through the articulated seat 62 of second with arc 3 is articulated mutually.

Center department is equipped with centre bore 13 in 1 upside center of domeplate, 1 downside center department of domeplate is equipped with the support, and the support includes backing plate 5, and backing plate 5 top both sides are equipped with second jack 7 through two stands 4 support connection domeplate 1 on backing plate 5, and the flexible end of second jack 7 is vertical upwards to be set up, the flexible end of second jack 7 passes in the centre bore 13, and fixed connection roof 8 is served in the flexible of second jack 7, and roof 8 upper surface is the arcwall face.

First openings 12 are symmetrically arranged on the arch plate 1, second openings 32 are arranged on the arch plate 3, and the first openings 12 and the second openings 32 are arranged in a one-to-one correspondence mode.

The invention provides a steel structure supporting structure for tunnel construction, which is mainly used for supporting a tunnel during tunnel excavation, has high applicability, can adjust the support along with the arch degree excavated in the tunnel during tunnel excavation, and has the following specific principle: promote the roof rebound through second jack 7, support the top center in tunnel, promote arc 3 through first jack 6 and rotate, support tunnel limit portion through arc 3, carry out three point stable support in this bearing structure can the tunnel like this, and the supporting effect is good. In use, as shown in fig. 4, the steel structure support structure provided by the invention is integrally fixed with the tunnel through the rivet 8, so that the support stability can be further improved, and the rivet 8 passes through the first opening 12 and the second opening 32 at a time and is riveted in the wall body of the tunnel.
