Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 3 and 4, the utility model discloses a cross interim support of river steel case bridge assembly sets up in the segmentation butt joint department 13 of steel case bridge, including corresponding setting up in tubular pile 1 of the vertical axis both sides of steel case bridge, be connected with erection bracing crossbeam 2 between the 1 top of tubular pile that both sides correspond, along steel case bridge transverse connection have horizontal vaulting pole 6 between the 1 upper portion of tubular pile that both sides correspond, horizontal vaulting pole 6 is located erection bracing crossbeam 2's below, be connected with vertical vaulting pole 7 between 6 middle parts of horizontal vaulting pole and the 2 middle parts of erection bracing crossbeam, be connected with diagonal vaulting pole 8 between the top of vertical vaulting pole 7 and the both ends of horizontal vaulting pole 6 respectively.
In the condition that adopts construction temporary bridge to carry out the construction of bridge, because the main structure form of construction temporary bridge generally adopts tubular pile 1 basis + steel bailey + distributive girder, the temporary support 14 of this application has adopted tubular pile 1 as the basis equally, set up the platform that installation supporting beam 2 formed the construction of steel box girder on tubular pile 1, in order to guarantee installation supporting beam 2's intensity, set up horizontal vaulting pole 6 in the below, the middle part sets up vertical vaulting pole 7, then set up corresponding diagonal vaulting pole 8, can effectively improve the stability and the atress performance of structure. When the construction temporary support 14 is erected, the temporary support 14 can be erected by using materials and construction machinery for the construction temporary support, if a 25t truck crane is matched with a vibration drawing hammer to perform support steel pipe pile 1 construction by using a fishing method, and a 25t truck crane is used for mounting an upper steel support, so that the materials and tools of the construction temporary support are fully utilized, the temporary support 14 is erected conveniently and fast, the cost is low, the stability of the temporary support 14 is high, and the mounting quality of the steel box bridge is improved. As shown in fig. 5 and 6, the temporary support 14 is arranged at the section butt joint 13 of the steel box bridge, and can be carried out on the temporary support 14 when the box girder segments 12 of the steel box bridge are assembled, welded, corrected and the like, so that the construction efficiency is effectively improved. As shown in fig. 1 and 2, the steel box bridge comprises 5 sections of box girder segments 12 with four segmental abutments 13, whereby 4 sets of temporary supports 14 are provided.
Both sides set up single tubular pile 1 respectively not only can make temporary support 14 top narrow, and stability is lower relatively moreover, therefore, in the preferred embodiment of this application, the vertical axis both sides of steel box bridge are provided with two at least respectively tubular pile 1 is connected with longeron tie-beam 3 between the tubular pile 1 top of unilateral, be connected with vertical vaulting pole 4 between the tubular pile 1 upper portion of unilateral, vertical vaulting pole 4 is located longeron tie-beam 3 below, two at least installation supporting beam 2 sets up on longeron tie-beam 3. The unilateral is provided with two at least tubular pile 1, then couples together it through vertical vaulting pole 4 and longeron tie-beam 3, combines the horizontal bearing structure who connects tubular pile 1 of both sides again, can connect into a whole with each tubular pile 1 to improve the reliability. Under this condition, can set up two or more installation supporting beam 2, increase the top surface width of temporary support 14, be favorable to personnel's construction operation.
Because installation supporting beam 2 is the most main construction platform, consequently sets up it on longeron tie-beam 3, and vertical tie-beam can provide stable installation base for installation supporting beam 2, and longeron tie-beam 3 also needs stable installation, consequently, in the preferred embodiment of this application, be provided with supporting backing plate 9 between tubular pile 1 and the longeron tie-beam 3. The diameter of the tubular pile 1 shown in fig. 4 is 63cm and the wall thickness is 10mm, while the supporting backing plate 9 is slightly larger than the tubular pile 1, and a steel plate with the thickness of 70cm × 70cm and 1cm is adopted. The temporary support 14 mainly bears vertical load, so that the installation supporting cross beam 2 and the longitudinal beam connecting beam 3 and the supporting base plate 9 can be welded discontinuously, and the construction efficiency is improved.
In order to keep a certain gap between the installation supporting beam 2 and the steel box bridge for facilitating later disassembly, in the preferred embodiment of the present application, the installation supporting beam 2 is provided with a plurality of pad beams 5 at intervals. The length of the pad beam 5 is not too long, and a small section of steel is adopted.
Horizontal vaulting pole 6, vertical vaulting pole 7, vertical vaulting pole 4, longeron tie-beam 3 and installation supporting beam 2 all can adopt current section bar preparation, in the preferred embodiment of this application, horizontal vaulting pole 6, vertical vaulting pole 7, vertical vaulting pole 4, longeron tie-beam 3 and installation supporting beam 2 all adopt the I-steel. Because the stress born by the longitudinal beam connecting beam 3 and the installation supporting cross beam 2 is larger, in the preferred embodiment of the application, the longitudinal beam connecting beam 3 and the installation supporting cross beam 2 both comprise at least two I-shaped steels spliced in parallel. In the embodiment shown in fig. 3-6, the transverse stay bar 6, the vertical stay bar 7 and the longitudinal stay bar 4 are all made of single 28# i-steel, the longitudinal beam connecting beam 3 is made of three 28# i-steel spliced in parallel, the mounting and supporting cross beam 2 is made of two 45# i-steel spliced in parallel, and the pad beam 5 is made of two 10# i-steel spliced in parallel.
In order to facilitate personnel to go up and down and stand, corresponding springboard 11 can be laid in the setting, for example in order to facilitate the construction and installation of temporary support 14, both sides tubular pile 1 one side in opposite directions all is connected with branch 10, springboard 11 has all been laid on branch 10 and the horizontal vaulting pole 6. After the springboard 11 is paved on the supporting rods 10, the installation of the transverse supporting rods 6 above the supporting rods is convenient, the structures such as the vertical supporting rods 7 and the longitudinal supporting rods 4 are convenient to install after the springboard 11 is paved on the transverse supporting rods 6, and in addition, the springboard 11 can be paved at other places where needed.
