Abstract
The utility model discloses a steelwork supporting device for shaft sinking utilizing a permanent concrete headframe, which comprises a steel plate used for fixedly connecting. Slots are uniformly distributed on the surface of the steel plate, each slot is correspondingly provided with a steel rod, one end of the steel rod is welded into the slot, the other end of the steel rod is bended into a hook to be connected with beams of the permanent concrete headframe in a casting mode, joints of the steelwork supporting device are embedded on four vertical posts in the middle of the headframe and vertical posts of the wall of the headframe, bended ends of the steel rod of the joints are connected with the beams of the permanent concrete headframe in a casting mode, and the vertical posts are welded onto the steel plate of the steelwork supporting device via profile steel so as to form a drilling platform. The steelwork supporting device only needs to be embedded on the concrete vertical posts, and the subsequent mounting process only includes steel beam welding, so that process is simple, preparing construction period can be greatly shortened, usage of steel can be greatly reduced when in comparison of setting up a profile steel structure. Further, integral stability and safety of the steel work are greatly improved by checking embedded parts and welding joint structures and optimizing arrangement of reinforced rib plates.
Description
Technical field:
When the utility model relates to colliery and the sinking shaft of the permanent concrete headframe of metal mine mine utilization, needs for the ease of the shaft sinking driving and masonry construction, need build temporary steel structure platform field, particularly at the steel work supported joint device that bears under the overweight load situation.
Background technology:
When colliery and the sinking shaft of the permanent concrete headframe of metal mine mine utilization, in order to arrange the head sheave of the required suspention construction equipment of shaft of vertical well sinking shaft, wire rope, cable, need to arrange interim sinking shaft sheave wheel platform that this platform need bear overweight load.
General alternative mode has two kinds, a kind of is the concrete bearing Liangping platform sinking shaft that utilizes existing headframe, but exist existing podium level, intensity and wire rope rope stretching mode can't satisfy the requirement of construction safety during practice of construction, utilize rear platform to seal, the later stage civil engineering can't continue parallel construction.Another kind is to build formed steel construction on existing platform top to construct sheave wheel platform, and advantage is: design and construction voluntarily need not to intersect with civil engineering; Shortcoming is: 1. platform needs all to use shaped steel to build, and rolled steel dosage is big; 2. the concrete platform structure stress is big, and structure need be strengthened; 3. Zu Zhuan formed steel construction resistance to overturning is poor.
The utility model content:
The purpose of this utility model is to provide a kind of steel work bracing or strutting arrangement that utilizes the sinking shaft of permanent concrete headframe, the podium level that calculates according to the requirement of well rig, on the main bearing column of concrete headframe, utilize this device to build the interim sinking shaft sheave wheel platform of steel work, simplified the arrangement of interim sinking shaft sheave wheel platform, accelerated preparation speed, improve the safety of using, reduced the steel use amount
The purpose of this utility model is achieved by the following technical programs: utilize the steel work bracing or strutting arrangement of permanent concrete headframe sinking shaft, it is characterized in that, comprise a steel plate that is used for fixing connection, equiblibrium mass distribution has slot on the plate face of steel plate; Each slot correspondence is provided with a round steel, and an end of round steel is inserted and is welded in the slot, and the other end of round steel is bent into hook-shaped and permanent cast-in-place the building of concrete headframe beam and is connected.
Thickness 〉=the 20mm of described steel plate.
The quantity of described round steel is no less than 15.
The utility model is mainly used in colliery or metal mine when utilizing concrete headframe sinking shaft construction, on the available temporary steel structure platform of no concrete bearing structure platform.This steel work bracing or strutting arrangement is embedded in headframe middle part four root posts and headframe and stands like a wall on the post, and the round steel bending end of piecing devices is connected with permanent cast-in-place the building of concrete headframe beam, is welded on the steel plate of supported joint device formation sinking shaft platform between column by shaped steel.In order to satisfy the winch chord length, to face upward the requirement of drift angle, girder steel is extended to the headframe both sides, by same pre-buried these piecing devices on the peripheral main load-bearing concrete column of headframe.
The beneficial effect that the utility model is compared with prior art had is: 1, this steel work supported joint device, only need to get final product after pre-buried on the concrete column, the later stage installation only needs welded steel beam, and is simple in structure, operation is easy, especially easy construction in the confined space in headframe, quick.Compare to significantly reduce and prepare the duration with building the formed steel construction platform, also the significantly reducing of built-in fitting with steel material.2, pass through the checking computations to built-in fitting and welding line structure, the optimization that the reinforcement gusset is arranged, resistance to overturning, the safety of structure of steel work improve greatly.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model light plate structural representation.
The specific embodiment:
As shown in Figure 1 and Figure 2, the steel work bracing or strutting arrangement of the permanent concrete headframe of the utilization that the utility model provides sinking shaft, comprise a steel plate 1 that is used for fixing connection, thickness 〉=the 20mm of steel plate, 20 slots 2 of balanced layout on the plate face of steel plate 1, slot 2 does not penetrate steel plate 1, each slot 2 corresponding round steel 3, one end of round steel 3 is inserted and is welded in the slot, the other end bending of round steel 3 forms hook-shaped and permanent cast-in-place the building of concrete headframe beam and is connected, in order to guarantee the intensity of joint, the diameter of round steel 3 is more than 25mm, and the quantity of round steel 3 is no less than 15.
The utility model is mainly used on the available temporary steel structure platform of no concrete structure platform.Utilize permanent concrete headframe in the construction, by pre-buried supported joint in the headframe concrete column, set up the steel work sheave wheel platform, turn over the sinking shaft of cash platform.Steel work supported joint device of the present utility model is embedded in headframe middle part four root posts and headframe and stands like a wall on the post, the round steel bending end of piecing devices is connected with permanent cast-in-place the building of concrete headframe beam, be welded on the steel plate of supported joint device by two H700 * 300mm shaped steel between column, throat thickness is 10mm, forms the sinking shaft platform.By to the checking computations of built-in fitting and welding line structure, strengthen the optimization that gusset is arranged, resistance to overturning, the safety of structure of steel work improve greatly.
The foregoing description only is a better embodiment of the present utility model; describe technical conceive of the present utility model and essential implementation in detail; be not to be that protection domain of the present utility model is limited; all any simple modification and equivalent structure transformation or modifications of doing according to the utility model spirit essence all should be encompassed within the protection domain of the present utility model.
