In recent years, the continuous beam hanging basket construction technology is widely applied, has the advantages of less equipment, less supports, no span limitation and the like, is widely applied to the construction of bridges, and further, the construction process of continuous beams is mature day by day. In the construction process, the construction of the 0# block is the beginning of the construction of the whole bridge and is also the foundation of the construction of the whole continuous beam, and the preparation work for the construction of the 0# block is particularly critical, so the construction of the 0# block is the key and difficult point of the bridge construction. The 0# piece construction of conventional large-span continuous beam adopts the steel-pipe column support method that falls to the ground, but falls to the ground steel-pipe column support method and receives the topography condition influence great, and the application scene receives certain restriction, especially to aquatic mound steel-pipe column support, and the construction degree of difficulty is big, and is with high costs. Therefore, the embodiment of the present application, which is described below by way of specific examples, provides a bracket in the context of a 0# block construction.
As shown in fig. 1 to 12, an embodiment of the present application provides a bracket, provided on a pier body, for construction of a # 0 continuous beam, including: the mounting structure comprises an embedded part and a mounting beam; the embedded parts comprise at least two first embedded parts 211 and at least one second embedded part 212, the first embedded parts 211 are arranged on the side faces, close to the top face of the pier body, and the second embedded parts 212 are oppositely arranged on the side faces, below the first embedded parts 211, of the pier body; the mounting beam comprises a cross beam 221 and a support beam 222, one end of the cross beam 221 is connected with the first embedded part 211, and the other end of the cross beam 221 is arranged in a suspended mode; one end of the supporting beam 222 is connected to the second embedded part 212, and the other end of the supporting beam 222 is connected to the suspended end of the beam 221.
As described above, the cross beam 221 and the support beam 222 form a triangular structure, and it should be noted that the stability of the triangular structure is the highest, thereby improving the overall stability of the bracket. Compared with the construction method of the traditional construction support system, the construction method of the 0# block constructed by the triangular bracket method has great difference and innovation, simplifies construction details, is not influenced by terrain conditions during use, reduces the construction difficulty of the 0# block, is hinged by pins among all members, is simple and convenient, shortens the installation time, and has great popularization and application values.
It should be noted that, the connection modes mentioned in the embodiments of the present application all use pins or pin shafts for connection, all holes of each workpiece use drilled holes, on-site punching is not required, the finish degree of the hole wall and the pin shaft should be strictly executed according to the design requirements, the allowable machining error of each pin shaft and the hole diameter is ± 0.25mm, and the allowable error of the edge distance of the end hole is ± 0.5 mm. In addition, the cross beam 221 and the support beam 222 in the application are made of 128B I-steel, and the length, the thickness, the number and other parameters are determined through continuous field experiments.
Further, the embedded part comprises embedded steel bars 213 and embedded steel plates 214, the embedded steel bars 213 are arranged in the pier body, the inner side surfaces of the embedded steel plates 214 are welded with the outer ends of the embedded steel bars 213, and the outer side surfaces of the embedded steel plates 214 are matched with the outer contour of the pier body.
as described above, the inner side surface of the embedded steel plate 214 and the outer end of the embedded steel bar 213 are connected by welding, and during welding, a reasonable welding process needs to be made before welding to avoid welding deformation as much as possible, so that the deformation is controlled within a standard allowable range. In addition, the pre-buried steel bars 213 should adopt the whole finish-rolled twisted steel bars as much as possible, and both ends of the pre-buried steel bars are provided with nuts and anchor backing plates. The outer side surface of the embedded steel plate 214 is matched with the outer contour of the pier body, so that the shape of the outer side surface of each embedded steel plate 214 is different, but is matched with the outer contour of the pier body, the appearance is regular, the embedded steel plates 214 and the pier body can be well fused together, and the overall stability and consistency are improved.
Furthermore, the embedded part also comprises an ear plate 215, and the ear plate 215 is arranged on the outer side surface of the embedded steel plate 214; the cross beam 221 and the support beam 222 are hinged to the ear plates 215 of the corresponding embedded parts through pin shafts 216.
it should be noted that the ear plate 215 is a connecting plate, and in a steel structure, the connection between the rods is mostly completed by using the connecting plate as an enlarged connecting surface of the transition piece. The connecting plate is an important part, the net section of the connecting plate needs to be subjected to strength calculation, the bolt rivet needs to be subjected to riveting hole local pressure bearing calculation, and the welded joint needs to be subjected to tensile strength and shear strength calculation. The pin shaft 216 is arranged on the ear plate 215, that is, the cross beam 221 and the embedded part are hinged together through the pin shaft 216 under the fixation of the ear plate 215, and similarly, the supporting beam 222 and the embedded part are hinged together through the pin shaft 216 under the fixation of the ear plate 215; it should be added that the embedded parts, the ear plates 215, etc. represent only one kind of the same components, and are not specific to a fixed structure.
Specifically, the number of the cross beams 221 and the support beams 222 is at least two; two adjacent cross beams 221 are connected together by chords 223, and the cross beam 221 and the adjacent support beam 222 are connected together by braces 224.
Further, the main function of the chord 223 and the brace 224 is to make the bracket more solid as a whole, and the bracket can be connected as a whole by the interconnection of the chord 223 and the brace 224, so that the whole bears the gravity. The stay 224 functions similarly to the reinforcing bar, and the stability of the cross beam 221 is much improved by the stay 224.
Furthermore, the angle formed by the cross beam 221 and the support beam 222 is between 40 and 50 degrees; the support beam 222 is a double-spliced channel steel.
It should be noted that the angle formed by the cross beam 221 and the support beam 222 is between 40 ° and 50 °, and as can be seen from the force analysis, the gravity shared by the cross beam 221 and the support beam 222 is relatively uniform. For important stress-bearing parts, detailed inspection is required to ensure the stress safety of the structure, and the cross beam 221 and the support beam 222 support the whole bracket, so the stress condition of the cross beam and the support beam is considered seriously. Therefore, the whole stability can be improved due to the limitation of the angle, and the service life of the bracket is further prolonged. The supporting beam 222 adopts double-spliced channel steel, and the two 36B channel steel are spliced together, so that the overall bearing capacity of the supporting beam 222 can be improved.
Based on the same technical concept, the embodiment of the application also provides a pier, and the following embodiments can be specifically referred to.
The embodiment of the application also provides a pier, which comprises a pier body 1, a reinforcing part 3 arranged in the pier body 1 and two groups of brackets 2; the two groups of brackets 2 are oppositely arranged on two sides of the pier body 1, the reinforcing part 3 penetrates through the pier body 1, and two ends of the reinforcing part 3 are respectively connected with the first embedded parts 211 corresponding to the two groups of brackets 2; the reinforcement 3 includes a corrugated pipe, and a reinforcing bar provided in the corrugated pipe.
as described above, during the 0# block concrete pouring construction, the vertical pressure load of the concrete acting on the formwork is transmitted to the bracket 2 through the cross beam 221, the chord 223 and the stay 224 of the bracket 2 are self-balanced through the pin joint, and the vertical load on the bracket 2 is transmitted to the hinged embedded part through the chord 223 and the stay 224 and then transmitted to the pier body 1.
Specifically, the reinforcement 3 runs through and sets up inside pier shaft 1, links together the first built-in fitting 211 of pier shaft 1 both sides to make fixed more firm of first built-in fitting 211.
Furthermore, the cross section of the pier body 1 is oblong, a part of the first embedded parts 211 are arranged at the transition position between the plane and the curved surface of the pier body 1, and the other part of the first embedded parts 211 are arranged on the plane close to the transition position.
it should be noted that, the most commonly used structure is that the cross section of the pier body 1 is oblong, the pier body 1 can be divided into two parts, two semi-cylinders are combined with a cuboid, and then the place where the semi-cylinders are combined with the cuboid is set as a transition position. The installation of first built-in fitting 211 on pier shaft should be strictly according to the design position installation, avoids the unsatisfied design requirement of the structure atress of later stage installation. In order to achieve a better supporting effect, the first embedded parts 211 are arranged on the transition position and beside the transition position, so that the overall stability can be improved.
The construction of a continuous beam 0# block is used as a background, after all components are machined, the bracket 2 is assembled in a trial mode, and after the assembly is completed, a static load test is carried out to determine the overall stress condition of the bracket and the strength and deformation value of the bracket under the maximum load so as to eliminate inelastic deformation and set an accurate pre-lifting value. The static load test is carried out according to the simulated weight of 1.2 times of the one-time pouring amount of the 0# block, and the simulation is carried out in three times; 0-50% -100% -120% -unloading, measuring and recording raw data after the load of each stage is added, and providing a basis for pre-lifting.
