Abstract
The invention provides an implanted bridge deck continuous device that comprises boards that are made of elastic material, the middle parts or near the middle parts of which are provided with drainage grooves in the back, and the boards are provided with water falling mouths that are communicated with the drainage grooves. The invention can be buried and arranged ahead once for all in the continuous parts between adjacent girders before casting a bridge deck concrete level layer, and can be used as a casting bottom die when casting concrete, used for preventing concrete grout from draining, without the need of additional installation of a bottom die. After laying a bridge deck asphalt layer, the device is not easy to be damaged by the contraction and expansion due to temperature and the angle effect caused by live load, as the tensile resistance and bending resistance of the elastic boards. The drainage grooves in the back of the elastic boards allow rainwater to be drained in time from the two sides of the bridge even if the bridge deck has cracks, which is advantageous in preventing a bridge deck asphalt layer from rainwater damage, avoids the problem of the coping being encroached by rainwater, enhances the durability of the coping, and ensures the safety of the bridge structure.
Description
Technical field
The present invention relates to a kind of bridge floor continuation apparatus, refer more particularly to the bridge floor continuation apparatus that is embedded in the bridge floor.
Background technology
In the bridge of freely supported structure, its superstructure bridge floor structure at place continuously is one of importance that influences bridge security and application life.Adopted in the mode of locating increase bridge floor continuity reinforcement(bar) continuously in the past and handle to strengthen the bridge floor structure at place continuously, longer as bridge, the bridge floor that several are continuous is regarded an integral body as, and flexible continuous apparatus is set between adjacent integral.Even now can increase the continuously structural strength at place of bridge floor, but bridge floor can be fallen because of expanding with heat and contract with cold etc. former thereby more easily produce the crack, causing rainwater to ooze on the bent cap below the bridge floor at the place continuously.And because the freely-supported beam-ends certainly leads to the corner effect under the live load effect, the continuous position of bridge floor is tension repeatedly, it seems for a long time and must ftracture, and causes the bridge floor rainwater to infiltrate along the crack.Estimate through investigation, bent cap more than 80% all has been subjected to the water enchroachment (invasion) evil of this class, and rainwater oozes behind the bent cap end face and air, moisture in dust mix and form mud, cause moisture to be long-term stored at the bent cap end face, and encroach on the bent cap side gradually, greatly reduce the durability of bent cap, thereby influenced whole Structure Safety for Bridge.In addition, because the influence of construction technology and external condition, the continuous position of this bridge floor often is very easy to damage, and about 20% bridge floor promptly needs to pour into a mould again this part concrete after being open to traffic 2 years, in time-consuming, brought great inconvenience to driving.
Summary of the invention
Technical problem to be solved by this invention provides a kind of structural strength that can strengthen the continuous place of bridge floor and improves the bridge security and the implantation type bridge floor continuation apparatus in application life.For this reason, the present invention by the following technical solutions: it comprises the plate that elastomeric material is made, and the back side at the position of the centre of described plate or close centre is provided with rhone, offers the drain gully that communicates with rhone on the described plate.Owing to adopt technical scheme of the present invention, the present invention can be before building the bridge deck concrete leveling layer the disposable pre-buried continuous place that is installed in the adjacent beams body, can be used as the bed die of building during concreting again, prevent to ooze under the concrete slurry, and no longer need to install in addition bed die.After finishing deck asphalt layer and mating formation, because the stretching-resisting bending-resisting folding endurance energy of elastic plate itself, for because temperature causes corner effect flexible and that cause owing to live load, this device is difficult for destroyed.Rhone at the elastic plate back side, even can be so that behind the bridge floor generation crack, oozing the rainwater that falls can in time discharge from the bridge both sides, help avoid the generation of deck asphalt layer water destruct, also stop bent cap and suffered the problem that rainwater is encroached on, strengthen the durability of bent cap, guaranteed Structure Safety for Bridge.
Description of drawings
Structural representation when Fig. 1 is implanted in the bridge floor for one embodiment of the present invention.
Fig. 2 is the vertical view of one embodiment of the present invention.
Fig. 3 is an enlarged drawing of the present invention among Fig. 1.
The specific embodiment
With reference to accompanying drawing.The present invention includes the plate 1 that elastomeric material is made, the back side at the position of the centre of described plate or close centre is provided with rhone 2, offers the drain gully 3 that communicates with rhone on the described plate.
As shown in Figure 1, plate 1 is erected at the continuously upper surfaces at place of adjacent beams body 101 and 102, and rhone 2 is in the slit between beam body 101 and 102.Drawing reference numeral 103 is a bridge deck concrete, and the present invention implants wherein.Drawing reference numeral 105 is conventional deck paving reinforcing bar or steel mesh reinforcement.
As shown in Figure 2, rhone 2 is outside ejecting plate is extended in plate 1 side, and in the present embodiment, the top of rhone extension is sealed, and drawing reference numeral 104 is a bridge protective railings, and rhone 2 may extend to the guard rail position side and will ooze the water discharge of raining.
As shown in figs. 1 and 3, cave in gradually towards the drain gully direction in the surface of described plate, helps the discharging of oozing the rainwater that falls from the continuous place, crack of bridge floor like this.In the present embodiment, the surface of described plate sticks the permeable cloth 4 that hides drain gully at least, like this, and the bridge construction behind the more convenient implantation the present invention of energy, concrete grout when permeable cloth 4 is constructed so long as water can ooze can't ooze the cloth that falls and get final product, such as geotextiles.
In the present embodiment, as shown in Figure 1, 2, 3, wear in the described plate and be connected with reinforcing bar 5; The reinforcing bar that described reinforcing bar comprises that a side of the bridge floor length direction of slave plate penetrates and passes from opposite side, and the part outside the plate of being in of the described reinforcing bar that penetrates and pass from opposite side from a side upwards bends up 51 and have a welding section 52 with deck paving reinforcing bar or reinforcing bar 105 welding.Like this, the present invention can be connected to form the overall space structure with the perfection of deck paving steel mesh reinforcement, further guarantee the continuous and concrete globality of mating formation of bridge floor, enhancing reduces the tension degree that concrete causes to the ability to bear of the stress because the beam slab that temperature causes stretches and to because live load causes the ability to bear of the stress that beam slab end corner effect causes.
In the present embodiment, described plate and rhone adopt rubber and are cast for one or adopt plastics and be cast for one, more convenient like this manufacturing.When cast, can simultaneously reinforcing bar 5 be imbedded and cast together.
Described plate also can adopt different materials with rhone.
