Obviously, the construction joint adopts the stagger joint principle to be arranged, thereby avoiding straight joints, increasing light propagation paths, weakening light radiation, and achieving better protective performance.
Description
Technical field
The utility model relates to the structure of constuction joint in a kind of concrete work, particularly relates to the structure of constuction joint in a kind of safeguard structure concrete work.
Background technology
At present, in the concrete work,, often adopt the Crack Control technology in order to guarantee the quality of concrete structure, promptly the comprehensive technical measure by aspects such as design, construction, materials with Crack Control in harmless scope.For example, on material, can choose suitable raw material and optimize concrete mix, water process meanses such as the rate of temperature fall of smashing molding temperature, internal-external temperature difference, heat and moisture preserving maintenance, jumping storehouse construction and go up to take to control in design and construction.More common means are when concreting, control the length or the volume size of each concreting, and concrete is divided into several storehouses, to reduce the crack that produces because of external constraint, so are convenient to form constuction joint between the concrete storehouse.
In addition, in daily construction, because the influence of factors such as weather, machinery is difficult to once finish concrete building, so have between the concrete of first after-pouring, form bonding surface, i.e. constuction joint.
For example, in the safeguard structure engineering, concrete is after building, because the hydration of cement discharges a large amount of heats of hydration, because protective shielding wall surface just may cause the inside concrete crack with the cross section middle portion temperature difference is excessive; In addition, if protective shielding wall surface temperature and ambient air excessive temperature differentials will cause the wall external crack.So if do not take corresponding crack Control Measures, the protective shielding wall very easily produces the crack, causes it can't satisfy the process for protecting requirement.Yet the place that constuction joint is set tends to become the weak link of barrier propterty again, so how constuction joint is set, makes it not only satisfy the demand of Crack Control but also can guarantee that the barrier propterty of barrier shield has become particularly important.
The utility model content
The purpose of this utility model is to provide a kind of constuction joint, with demand and the construction needs that satisfy Crack Control, guarantees the barrier propterty of barrier shield simultaneously.
The utility model provides a kind of constuction joint for this reason, provides bonding surface between the concrete for first after-pouring, and it comprises: one first bonding surface; One second bonding surface; And one the 3rd bonding surface, wherein, first bonding surface is parallel to each other with the 3rd bonding surface and second bonding surface is connected between first bonding surface and the 3rd bonding surface and vertical with it.
Further, above-mentioned first bonding surface or the 3rd bonding surface and second bonding surface intersect formation L type bonding surface.
Further, has the wire lath template on the bonding surface of above-mentioned constuction joint.
Further, above-mentioned wire lath template is fast easily sealing web frame.
Further, above-mentioned wire lath template is formed by the compacting of hot dipping degree zinc-iron sheet.
Further, above-mentioned wire lath template is the copper coin net.
Further, the bonding surface of above-mentioned constuction joint is cutter hair knot structure.
Further, described constuction joint also comprises: one the 4th bonding surface; One the 5th bonding surface, parallel with above-mentioned the 3rd bonding surface, wherein the 4th bonding surface is connected between the 3rd bonding surface and the 5th bonding surface and is vertical with it.
Further, above-mentioned the 3rd bonding surface or the 5th bonding surface and the 4th bonding surface intersect formation L type bonding surface.
In sum, the disclosed constuction joint of the utility model adopts the setting of fissure of displacement principle, thereby avoids the straight line straight joint, has increased the round of light, thereby light radiation is weakened, and has reached barrier propterty preferably.
Description of drawings
The schematic cross-section of the barrier shield that Fig. 1 is provided for the utility model one embodiment with constuction joint;
The schematic cross-section of the barrier shield that Fig. 2 is provided for another embodiment of the utility model with constuction joint.
The specific embodiment
In the safeguard structure engineering, often expect the barrier shield continuously poured in one, yet, build and reserve constuction joint and weakened the barrier propterty that the constuction joint place is located thereby have to carry out segmentation because the demand of Crack Control and construction need.For this reason, adopt fissure of displacement principle and constuction joint is set in the utility model, thereby avoid the straight line straight joint.With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Please refer to Fig. 1, the schematic cross-section of the barrier shield that it is provided for the utility model one embodiment with constuction joint.As shown in the figure, provide bonding surface between the concrete 10,20 of constuction joint 30 for first after-pouring, it comprises first bonding surface 31, second bonding surface 32 and the 3rd bonding surface 33, wherein first bonding surface 31 is parallel to each other with the 3rd bonding surface 33 and second bonding surface 32 is connected between first bonding surface 31 and the 3rd bonding surface 33 and vertical with it.As figure, first bonding surface 31, the 3rd bonding surface 33 and second bonding surface 32 intersect formation L type bonding surface.
In addition, the bonding surface of constuction joint 30 all adopts fast easily sealing net, becomes mesh and skeleton with hot dipping degree zinc-iron sheet by machine pressing, is used as permanent disposable template and uses.Certainly, it also can be the copper coin net.So when concreting, the surface can be observed inside and builds situation, lowers the risk of space, honeycomb, pitted skin; After the concreting, the dihedral and the concrete of its mesh embed automatically, produced a machinery seam, form rough surface on the bonding surface, give continuing concreting provides comparatively desired binding face, and need not manually to cut, processing such as hacking, cleaning, maintenance, can carry out secondary to build operation, make new-old concrete be combined into firm integral body, the quality of butt joint has powerful viscous force and shearing resistance.Fast easily sealing net is stayed the surface behind concreting, can play strengthening action, prevents the concrete surface layer drying shrinkage, the temperature shrinkage crack.
Certainly, also can cut a hole hair and handle, form cutter hair knot structure and provide comparatively desired binding face for new-old concrete the bonding surface of constuction joint 30.
Please continue with reference to figure 2 schematic cross-section of the barrier shield that it is provided for another embodiment of the utility model with constuction joint.This moment, constuction joint 40 was the concave-convex type bonding surface, it is with respect to above embodiment, except having first bonding surface 41 and the 3rd bonding surface 43 that is parallel to each other and being connected in therebetween second bonding surface 42, the 4th bonding surface 44 and the 5th bonding surface 45 have also been set up, wherein the 5th bonding surface 45 is parallel to that the 3rd bonding surface 43, the four bonding surfaces 44 are connected between the 3rd bonding surface 43 and the 5th bonding surface 45 and is vertical with it.Same, the 3rd bonding surface 43, the 5th bonding surface 45 and the 4th bonding surface 44 intersect formation L type bonding surface.
As seen, the utility model adopts fissure of displacement principle and constuction joint is set, thereby avoids the straight line straight joint, has increased the round of light, thereby light radiation is weakened, and has reached barrier propterty preferably.It adopts fast easily sealing net as permanent disposable template in the forming process of constuction joint simultaneously, thereby has formed comparatively desired binding face, makes new-old concrete be combined into firm integral body, and the quality of butt joint has powerful viscous force and shearing resistance.
