Abstract
The utility model discloses an L-shaped connecting piece for a steel support and a feet-lock anchor rod. The connecting piece comprises the feet-lock anchor rod and the steel support, and is characterized in that the L-shaped connecting piece is formed by connecting a transverse reinforcing steel bar and a longitudinal reinforcing steel bar; the transverse reinforcing steel bar is firmly welded with the steel support by double-sided welding; and the longitudinal reinforcing steel bar is firmly welded with the feet-lock anchor rod by double-sided welding. By using the connecting piece provided by the utility model, the steel support is connected with the feet-lock anchor rod, so that the deformation of the steel support is greatly reduced; the stability of the steel support is enhanced; and the safety of the chamber is increased.
Description
Technical field
The utility model belongs to the Hydraulic and Hydro-Power Engineering technical field, is specifically related to a kind of L shaped steel and supports and the lock foot anchoring stock connector.
Background technology
In Hydraulic and Hydro-Power Engineering is built; Cavern excavation often runs into the situation of geological conditions difference, because geological conditions is poor, it is more that once supporting is used the situation of steel shotcrete support; Traditional and steel supports supporting supporting to be had: adopt two grade reinforcing steels to be welded to connect between steel supports; The tunnel abutment wall adopts lock foot anchoring stock to pin steel and supports, and along with the continuous summary of construction, above-mentioned construction is still waiting to improve to the stabilization that steel supports self; Often occur in the construction because steel supports the situation that the steel supporting deformation appears in the self stability deficiency; Have a strong impact on the stable of tunnel, follow-up can only be to set up again or it is added strong supporting etc., causes repeating and the adverse effects such as increase of construction cost of unnecessary potential safety hazard, construction.
Summary of the invention
The purpose of the utility model is to overcome conventional steel to support in the construction lock foot anchoring stock construction back steel to support self stability still not enough; Provide a kind of easy construction, cost is low, construction effect is good L shaped steel to support and the lock foot anchoring stock connector; This connector makes the steel support be connected with lock foot anchoring stock is organic; Form a unified integral body, strengthened steel and supported the stable of self, and reliable construction quality.
The technical scheme of the utility model is: L shaped steel supports with the lock foot anchoring stock connector and comprises that steel supports, the lock foot lever; It is characterized in that transverse reinforcement and longitudinal reinforcement are connected to form the L type; Transverse reinforcement supports firm welding with double welding and steel, and longitudinal reinforcement is with double welding and lock foot anchoring stock firm welding.
The connector of the utility model supports steel with lock foot anchoring stock is organic and couples together, and has reduced the distortion that steel supports greatly, has strengthened steel and has supported the stable of self, has increased the safety of cavern.
Description of drawings
Fig. 1 is the L type connector structural representation of the utility model.
Among the figure: 1-is a transverse reinforcement, and 2-is a longitudinal reinforcement, and 3-is that steel supports the 4-lock foot anchoring stock.
The specific embodiment
As shown in Figure 1, L shaped steel supports with the lock foot anchoring stock connector and comprises steel support 3, lock foot anchoring stock 4, transverse reinforcement 1, longitudinal reinforcement 2; Transverse reinforcement, longitudinal reinforcement adopt Φ 22 secondary reinforcement fabrications, the long 10cm of transverse reinforcement, the long 22cm of longitudinal reinforcement; With transverse reinforcement and longitudinal reinforcement welding; Promptly form " L type " connector, laterally adopt double welding and steel to support firm welding, vertically adopt double welding and lock foot anchoring stock firm welding.Realize that steel supports and lock foot anchoring stock organic be connected in aggregates.
Claims (2)
1. a L shaped steel supports and the lock foot anchoring stock connector; Comprise that lock foot anchoring stock, steel support; It is characterized in that connecting into L type connector by transverse reinforcement and longitudinal reinforcement, transverse reinforcement supports firm welding with double welding and steel, and longitudinal reinforcement is with double welding and lock foot anchoring stock firm welding.
2. L shaped steel according to claim 1 supports and the lock foot anchoring stock connector, it is characterized in that the long 10cm of transverse reinforcement, the long 22cm of longitudinal reinforcement.
