Abstract
The utility model discloses a structure for connecting ejector rods between steel tube concrete supports. The structure comprises a plurality of steel tube concrete supports which are arranged in parallel, wherein every two adjacent steel tube concrete supports are connected through a plurality of ejector rods, each ejector rod is a hollow steel tube, the hollow steel tubes are filled with concrete, ejector rod connectors are welded to the outer wall of each steel tube concrete support, a through hole is formed in each ejector rod connector, bolts are arranged on the end portions of the ejector rods, the bolts are fixedly arranged in the through holes respectively, and the two ends of each ejector rod are respectively provided with a cambered surface which is matched with the outer wall of the corresponding steel tube concrete support. The constraint conditions of the steel tube concrete supports are changed, the overall stability and the overall deformation resistance capacity of the steel tube concrete supports are improved, and the ejector rods have high compressive strength and the high deformation resistance capacity.
Description
Technical field
The utility model relates to a kind of steel pipe concrete bracket, relates in particular to push rod syndeton between a kind of steel pipe concrete bracket.
Background technology
Along with coal resources are to deep mining, soft-rock tunnel problem is more and more outstanding.Due to the continuous increase of mining depth, geological environment constantly worsens, and geostatic stress increases, fragmented rock body increases, roadway maintenance difficulty, geological disaster increases, and the stability problem of roadway surrounding rock and supporting and protection structure has become restriction coal resources to the matter of utmost importance of deep mining.
A large amount of engineering practices show, in many situations, existing roadway surrounding rock control technology still can not be controlled the strong deformation of high stress and soft rock mine roadway effectively, and the reason that causes this situation is not that supporting intensity is inadequate, but because the structural stability of existing supporting bearing structure is poor, be difficult to effectively control the strong deformation of roadway surrounding rock.
In prior art, steel pipe concrete bracket supporting, as a kind of novel support form, has the advantages such as bearing capacity is high, support cost is low.
At least there is following shortcoming in above-mentioned prior art:
Between frame, during unbraced structure, resistance to overturning is poor, is unfavorable for bringing into play integer support advantage.
Utility model content
The purpose of this utility model is to provide push rod syndeton between a kind of steel pipe concrete bracket of good stability.
The purpose of this utility model is achieved through the following technical solutions:
Push rod syndeton between steel pipe concrete bracket of the present utility model, comprise many steel pipe concrete brackets that are arranged in juxtaposition, between adjacent two steel pipe concrete brackets, by many push rods, connect, described push rod is hollow steel pipe, in described hollow steel pipe, is filled with concrete.
The technical scheme being provided by above-mentioned the utility model can be found out, push rod syndeton between the steel pipe concrete bracket that the utility model embodiment provides, owing to connecting by many push rods between adjacent two steel pipe concrete brackets, change the constraints of steel pipe concrete bracket body, improved stability and the non-deformability of steel pipe concrete bracket integral body; Again because push rod is to load the concrete filled steel tubular member that concrete forms in steel pipe, thereby make push rod there is higher compressive strength and non-deformability.

The specific embodiment
To be described in further detail the utility model embodiment below.
Push rod syndeton between steel pipe concrete bracket of the present utility model, its preferably the specific embodiment be:
Comprise many steel pipe concrete brackets that are arranged in juxtaposition, between adjacent two steel pipe concrete brackets, by many push rods, connect, described push rod is hollow steel pipe, in described hollow steel pipe, is filled with concrete.
On the outer wall of described steel pipe concrete bracket, be welded with mandril joint, described mandril joint is provided with through hole, and the end of described push rod is provided with bolt, and described bolt is fixed in described through hole.
The two ends of described push rod are provided with the cambered surface that the outer wall with described steel pipe concrete bracket matches.
The utility model is welding joint on steel pipe concrete bracket, and push rod is connected with bolt with the joint on support.Change the constraints of steel pipe concrete bracket body, improve stability and the non-deformability of steel pipe concrete bracket integral body.
Push rod is in steel pipe, to load the concrete filled steel tubular member that concrete forms, thereby makes push rod have higher compressive strength and non-deformability.
Specific embodiment:
As shown in Figure 1, as shown in Figures 2 and 3, the stake body being connected by push rod etc. as shown in Figure 4 for push rod for mandril joint on support.
Support adopts push rod method of attachment: adopt push rod to connect, adjacent two supports are connected as a single entity, obviously improve the resistance to overturning of support;
Push rod material is concrete filled steel tubular member: push rod is encased structures, and concrete filled steel tube push pipe compressive strength is large, non-deformability is strong, low cost;
Mandril joint mode: welding joint on stake body, push rod is connected with bolt with joint, and push rod is mainly brought into play compressive property also has certain tensile property simultaneously.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
