With reference to shown in Fig. 1, preferred embodiment is provided for the utility model.
A kind of support construction reinforced to beam type pontic joint, mainly for the protection of the bridge of beam type
The joint of body prevents the situation to fail occur due to generating stress concentration at lower bracket.It includes end and is formed with lower ox
First pontic 1 of leg and corresponding the second pontic 9 with the cooperation of the first pontic 1, the second pontic 9 with being set at lower bracket cooperation
There is upper bracket, upper bracket inlays cooperation with lower bracket, and lower bracket lower end is provided with 2 structure of joist of the lower bracket of carrying, 2 knot of joist
Structure carries out stretch support by anchor cable structure 4, and one end of anchor cable structure 4 is connected in 2 structure of joist, the other end of anchor cable structure 4
It is attached upward across the first pontic 1 in the upper end of the first pontic, i.e., 2 structure of joist is by stress on anchor cable structure 4, and causes
2 structure of joist plays the role of supporting the first pontic 1 and the second pontic 9.
Specifically, the width of 2 structure of joist is equal to the width of the first pontic 1,2 structure of joist includes outer box hat and lattice
Support construction 10, lattice support construction 10 are arranged on 9 lower section of the second pontic, are an entirety with outer steel body, are used to support second
Pontic 9, outer steel body are supported below lower bracket and extend lower bracket so that outer steel body can from 1 lower end stress of the first pontic,
Inside outer box hat there is the cavity volume of closing, full concrete is filled in cavity volume, outer box hat also has the rope pipe structure 6 of up/down perforation,
Anchor cable structure 4 is from top to bottom supported connection across rope pipe structure 6 in the lower end of outer box hat.
A kind of support construction reinforced to beam type pontic joint provided in this embodiment, structure construction letter
It is single, securely and reliably, be solve the problems, such as bracket under cantilever glider bridge, upper bracket stress effective way.The scale of construction is small, and bridge headroom is invaded
It accounts for less, does not influence bridge beauty after reinforcing, do not influence to pass through on bridge and under bridge.It Steel material part can be after the completion of factory process again
In-site installation is transported to, quality is easily guaranteed, and the site operation period is short, and low cost is easy to maintain, and it is convenient that later stage pipe is supported.Increase
The structure of joist 2 using joist 2 gives the support force of the first pontic 1 and the second pontic 9 upward, alleviates lower bracket
Stress burden, improve the service life of pontic entirety.
Due to the first pontic 1 and the difference of the accuracy of manufacture of the different and joist 2 of the assembly precision of the second pontic 9, work as support
After 2 structural support of beam is below the lower bracket, lattice support construction 10 not necessarily just can play the second pontic 9 support and make
With in order to enable lattice support construction 10 good can give the appropriate support force of the second pontic 9 upward, in the present embodiment
In, lattice support construction 10 is not direct to be contacted with the second pontic 9, but is set between 10 and second pontic 9 of lattice support construction
Be equipped with support component, the second pontic 9 supported using support component, and specifically, could be provided as support component be can be with
The element of height is adjusted, just can offset rigging error and foozle in this way.
In order to enable joist 2 can be by good fixation, in the present embodiment, outer box hat includes upper plate, upper plate with
The lower surface of first pontic 1 is fixedly connected using multiple bolts 3 in array arrangement.
For the carry out stress for enabling anchor cable structure 4 more intact, in the present embodiment, anchor cable structure 4 includes two
Anchor cable group, opposite tilt is disposed to extend two anchor cable groups from the bottom to top, i.e., as described in Figure have two rows of anchor cable groups, two rows of anchor cable groups
Upward towards tilted, the mode that two groups of anchor cables are in tilted layout causes the positioning of 2 structure of lower end joist more to stablize, and will not occur
The offset of horizontal direction.
In a practical situation, after 2 structure of joist has used certain time limit, anchor cable can occur a degree of elongate and become
Shape, this just causes the positioning of 2 structure of joist that can become to be not sufficiently stable, in order to improve this problem, in the present embodiment, anchor cable knot
Two ends of structure 4 are respectively the stretching end 8 that its stretching dynamics and drawing length is adjusted and the fixing end 5 being fixedly connected, Gu
Fixed end 5 is the one end being connect with pontic, and it is the one end being connect with 2 structure of joist to stretch end 8, in this way, when anchor cable structure 4 loosens
Afterwards, it can be adjusted to stretching end 8, anchor cable structure 4 is made to continue to keep original drawing force.
Processing to fixing end 5 for convenience, in the present embodiment, when fixing end 5 is constructed, the upper surface of pontic, which is excavated, to be had
Anchor slot, fixing end 5 is arranged on anchor slot, and after the completion of construction, concrete is filled in anchor slot, makes pontic upper surface smooth multiple
It is former.
Particularly, the length of 2 structure of joist is more than the length of bracket so that the upper loading end of 2 structure of joist carries ox
Leg, and abutted with the lower face of pontic, such 2 structure of joist can preferably obtain equilibrant force from pontic.
For the ease of late detection and maintenance, stretch end 8 and be provided with detachable protective cover 7, after dismantling protective cover 7, anchor
Rope can carry out benefit tensioning, convenient for adjustment structure stress..
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
