Abstract
The utility model discloses a double-layer structured reinforced concrete plate with a novel stool-shaped supporting rib. The double-layer structured reinforced concrete plate comprises a concrete-plate upper-layer structure rib, a stool-shaped supporting rib and a concrete cushion layer; the stool-shaped supporting rib forms a three-foot claw-shaped stool by welding a U-shaped steel rib and a diagonal bracing rib, the upper part of the three-foot claw-shaped stool is connected with the concrete-plate upper-layer structure rib in a tying manner, and the lower part of the three-foot claw-shaped stool is supported on the concrete cushion layer. The double-layer structured reinforced concrete plate with the novel stool-shaped rib has the advantages of convenient, fast and very simple fabrication, effective increase of a stool-shaped rib fabrication speed of a worker, easy control of fabrication dimension and high stress bearing capability; besides, the double-layer structured reinforced concrete plate is more steady than the traditional stool-shaped rib, the elevation of the upper-layer rib can be effectively controlled, a rib exposure phenomenon after concrete pouring seldom happens, the thickness of a rib protecting layer is effectively guaranteed, and the construction quality of the upper-layer rib is improved.
Description
Technical field
The utility model relates to a kind of double-decker reinforced concrete plate with Novel barricade muscle.
Background technology
The concrete slab of double-decker arrangement of reinforcement, the quality of its top reinforcement in construction is the Focal point and difficult point of engineering construction always.Existing double-decker reinforced concrete plate adopts traditional supporting steel bar, and structure as shown in Figure 1, comprises supporting steel bar 1, concrete plate superstructure arrangement of reinforcement 2 and 3 and concrete bed course 4 etc.Adopt traditional supporting steel bar to have following defect: first it adds difficult control of quality in man-hour, to having relatively high expectations of operating personnel, is prone to bottom surface or top cross-arm injustice; Secondly in each operation construction of plate, top reinforcement is subject to after jamming on of personnel and machinery, and supporting steel bar is yielding or topple along 45 degree are oblique, causes upper layer plate-rib to cave in or buckling deformation.Therefore,, when the concrete slab member of double-deck arrangement of reinforcement is constructed, the stability that supporting steel bar is good and supporting capacity are the keys that affects top reinforcement construction quality.
Utility model content
The utility model has overcome the shortcoming in present technology; a kind of double-decker reinforced concrete plate with Novel barricade muscle is provided; stressed by split heads tripod; realize its good stability and supporting capacity; make the top reinforcement of concrete slab member be difficult for deformation displacement; strictly control the absolute altitude of top reinforcement, avoided to a great extent the excessive common quality defect of top reinforcement protective layer thickness deviation simultaneously.
The technical solution of the utility model is: a kind of double-decker reinforced concrete plate with Novel barricade muscle, comprise concrete plate superstructure arrangement of reinforcement, supporting steel bar and concrete bed course, described supporting steel bar is welded to form tripod " pawl " type split heads by U-shaped reinforcing bar and diagonal brace reinforcing bar, tripod " pawl " type split heads top is connected with the colligation of concrete plate superstructure arrangement of reinforcement, and lower support is on concrete bed course.
Described U-shaped reinforcing bar adopts straight bar bending machine-shaping, its cross-arm length is bar diameter 8 times, cross-arm two ends are processed to form the bipod of U-shaped reinforcing bar by 90 ° of angular distortions.
The length of described diagonal brace reinforcing bar is identical with the bipod length of U-shaped reinforcing bar.
Described diagonal brace reinforcing bar one end full weld is connected in the middle of U-shaped reinforcing bar cross-arm, and pad weld bead height is more than or equal to 6mm.
The longitudinal reinforcement of described U-shaped reinforcing bar cross-arm and concrete plate superstructure arrangement of reinforcement and transverse reinforcement are all 45 ° of placements of level.
Described pad aligns with the longitudinal reinforcement of concrete plate superstructure arrangement of reinforcement and the crosspoint of transverse reinforcement, and is fixed together with galvanized wire colligation.
The bipod of described U-shaped reinforcing bar and diagonal brace reinforcing bar are all horizontal by 60 °～70 ° angles.
Compared with prior art; the utility model has the advantages that: easy to process quick; very simple, effectively to improve workman and process supporting steel bar speed, processing dimension is more easily controlled; there is stronger stress performance; more firm than traditional supporting steel bar, can effectively control top reinforcement absolute altitude, after concreting, rare dew muscle phenomenon occurs; effectively guarantee thickness of protection tier, improve the construction quality of top reinforcement.
Accompanying drawing explanation
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation of existing double-decker reinforced concrete plate;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
There is a double-decker reinforced concrete plate for Novel barricade muscle, as shown in Figure 2, comprise U-shaped reinforcing bar 1, diagonal brace reinforcing bar 2, pad 3, transverse reinforcement 4, longitudinal reinforcement 5, concrete bed course 6 etc., wherein:
U-shaped reinforcing bar 1 adopts straight bar bending machine-shaping, and its cross-arm (that is: the horizontal linear section of U-shaped reinforcing bar) length is that 8d(d is bar diameter), cross-arm two ends are processed to form U-shaped reinforcing bar 1 bipod by 90 ° of angular distortions; Diagonal brace reinforcing bar 2 adopts the clout after reinforcing bar processing, and its length is identical with U-shaped reinforcing bar 2 bipod length; Diagonal brace reinforcing bar 2 one end full welds are connected in the middle of U-shaped reinforcing bar 1 cross-arm, pad 3 weld bead heights are more than or equal to 6mm, when welding, can make easy interim brandreth for controlling supporting steel bar forming height, be convenient to control U-shaped reinforcing bar 1 and diagonal brace reinforcing bar 2 horizontal by 60 °～70 ° angles simultaneously.This supporting steel bar is after substructure reinforcing bar binding is complete, directly be placed on concrete bed course 6, when upper strata longitudinal reinforcement 5 and transverse reinforcement 4 colligation, supporting steel bar cross-arm is 45 ° of levels with longitudinal reinforcement 5, transverse reinforcement 4 and is placed on its position, crosspoint, supporting steel bar pad 3 aligns with longitudinal reinforcement 5, transverse reinforcement 4 crosspoints, and is fixed together with galvanized wire colligation.
This Novel barricade reinforcing bar is easy to process quick, and very simple, processing dimension is more easily controlled; U-shaped reinforcing bar 1 and diagonal brace reinforcing bar 2 length are little, can make full use of the clout after reinforcing bar processing.Meanwhile, supporting steel bar supporting capacity and stability are relatively good, and top reinforcement absolute altitude can effectively control construction time reveals muscle phenomenon after minimizing concreting and occurs, and improves the construction quality of top reinforcement.
