In this embodiment, the positioning device mainly comprises a template component 2, a supporting rod 6 and an elevation adjusting component 3. The template component 2 is used as a pouring template of pile cap part concrete, and the elevation adjusting component 3 is arranged on the template component 2 and is used for adjusting the elevation and levelness of the template component 2. In this embodiment, the elevation and levelness of the template assembly 2 can directly affect the positioning accuracy of the embedded steel plate 7, the fixed steel plate 4 and the anchor bolts 5 on the reinforcement cage, so that the elevation and levelness of the template assembly 2 can be conveniently adjusted, the elevation adjusting assembly 3 can be installed around the template assembly 2, and the precise adjustment of the elevation and levelness of the template assembly 2 can be realized through a plurality of elevation adjusting assemblies 3.
Since a rectangular concrete structure needs to be poured at the pile cap, the formwork assembly 2 is also arranged to be a rectangular structure, and is composed of a front formwork 23, a rear formwork 24, a left formwork 21 and a right formwork 22, wherein the front formwork 23, the rear formwork 24, the left formwork 21 and the right formwork 22 are connected end to form a pouring area, and concrete can be poured into the pouring area to form a required concrete member during construction. According to the construction requirements of the catenary foundation, the finally formed concrete member needs to be parallel to the railway extending direction, so the left template 21 and the right template 22 are perpendicular to the railway extending direction in the embodiment, and the supporting rods 6 are parallel to the railway extending direction.
The steel reinforcement framework needs to be hung into the dug pile foundation and pile cap before pouring, namely the upper end of the steel reinforcement framework can be located in a pouring area surrounded by four templates. And the embedded steel plate 7, the fixed steel plate 4 and the foundation bolts 5 are installed on the steel bar framework in a factory according to the design requirements. The steel reinforcement framework with the embedded steel plate 7, the fixed steel plate 4 and the foundation bolts 5 is integrally hoisted into the pile foundation during installation, and the positions of the embedded steel plate 7, the fixed steel plate 4 and the foundation bolts 5 are directly perceived as the final formed positions during pouring.
Therefore, the three parts are required to be ensured to be in the design positions before casting and in the casting process. For this purpose, in this embodiment, the support rods 6 are provided, the support rods 6 are parallel to the extending direction of the railway and are at least two, the upper ends of the support rods 6 are provided with positioning grooves 61, and the positioning grooves 61 on the two support rods 6 together form a rectangular positioning area. Since the size of the positioning groove 61 matches the size of the fixed steel plate 4, the fixed steel plate 4 can be restrained by the positioning groove 61 when the fixed steel plate 4 is located in the positioning groove 61. That is, when the support rod 6 is at the design position, the positioning groove 61 is at the design position, the fixed steel plate 4 is also at the design position, and the anchor bolt 5 and the embedded steel plate 7 connected with the same are both at the design position.
Specifically, the fixed steel plate 4 is positioned so that the support rod 6 can be positioned. In actual construction, a long reinforcement cage is adopted according to the depth requirement of the pile foundation, so that the whole reinforcement structure is divided into two parts for convenient transportation and hoisting, one part is the reinforcement cage, and the other part is the reinforcement cage.
During construction, the support rods 6 are firstly removed from the template assembly 2, then the reinforcement cage is hoisted into the pile foundation and suspended, and at the moment, the support rods 6 penetrate through the template assembly 2 and the reinforcement cage to temporarily support the reinforcement cage. And then hoisting the steel reinforcement framework, and welding and fixing the lower end of the steel reinforcement framework and the upper end of the steel reinforcement cage. Then the supporting rod 6 is taken down, the reinforcement cage and the reinforcement cage are integrally lowered to the design position, at the moment, the supporting rod 6 passes through the template assembly 2, and the positioning groove 61 is positioned at the design position. Finally, the whole steel bar structure is lowered, and the fixed steel plate 4 on the steel bar framework is embedded in the positioning groove 61. Because the supporting rod 6 passes through the formwork component 2, the supporting rod is movable only in the extending direction along the railway, so that the positioning groove 61 is convenient to adjust to the design position, and meanwhile, after the supporting rod 6 contacts with the fixed steel plate 4, the supporting rod 6 cannot displace along the extending direction of the railway under the gravity action of the whole steel bar structure, so that the whole steel bar structure is positioned.
According to the embodiment, the fixed steel plate 4 in the reinforcement cage is supported by the supporting rods 6 after the reinforcement cage is lowered, the fixed steel plate 4 is limited in the positioning grooves 61 on the supporting rods 6, the fixed steel plate 4 is positioned by the positioning grooves 61, meanwhile, the foundation bolts 5 installed on the fixed steel plate 4 and the embedded steel plates 7 connected with the foundation bolts 5 are positioned, so that the accurate positioning of the positions of the reinforcement cage and the reinforcement cage, the positions of the embedded steel plates 7 and the positions of the foundation bolts 5 are realized, the deviation can not occur in the concrete pouring and vibrating process, the operation is simple, the technical effect of improving the construction efficiency is facilitated, the adverse effects of the embedded steel plates 7 and the positions of the foundation bolts 5 in the construction process, the installation of upright posts of the contact net is affected, and the problems of quality and potential safety hazards of subsequent construction and operation safety burying are solved.
In order to enable the support rod 6 to penetrate through the upper ends of the left template 21 and the right template 22, the upper ends of the left template 21 and the right template 22 are provided with the mounting groove 8, the support rod 6 penetrates through the mounting groove 8, the upper end of the mounting groove 8 is provided with an opening, and the support rod 6 can be detached or transversely pulled out along the opening direction when detached. Because the upper end of the mounting groove 8 is open, when the reinforcement cage is supported and positioned by the support rod 6, the cooperation of the support rod 6 and the template assembly 2 can well restrict the displacement of the reinforcement cage in the horizontal direction, but cannot well prevent the reinforcement cage from floating upwards.
Therefore, in order to prevent the reinforcement cage from floating up in the casting process, mounting holes are formed in the upper ends of the left and right templates 21 and 22, and the support rods 6 pass through the mounting holes. The mounting hole is for mounting groove 8, and its circumference is closed structure, can carry out omnidirectional spacing to bracing piece 6 by the mounting hole after bracing piece 6 passes the mounting hole. After the template component 2 is fixed with the ground (installation foundation), the supporting rods 6 can better position the steel reinforcement framework and prevent the steel reinforcement framework from floating or moving horizontally. The support bar 6 can be a channel steel.

Specifically, when the elevation is adjusted, the adjusting nut at the upper part can be rotated to move upwards, and then the adjusting nut at the lower part can be rotated to adjust the height of the positioning steel plate 31, namely, the height of the template assembly 2. After being adjusted in place, the adjusting nut at the upper part is rotated to move downwards and lock the positioning steel plate 31, so that the template assembly 2 is positioned at a set elevation. The levelness of the template assembly 2 can be adjusted by cooperation of the elevation adjustment assemblies 3 in four directions.
According to the design construction requirement, pile cap concrete member is comparatively close to road bed cable groove, consequently does not possess the mounted position of location steel sheet 31 and adjusting bolt 32 in the one side of template subassembly 2 close to road base cable groove. In order to ensure that four positioning steel plates 31 can be positioned at four corners of the form assembly 2, two positioning steel plates 31 are disposed at the front end of the front form 23, and the other two positioning steel plates 31 are disposed at the rear end of the left form 21 and the rear end of the right form 22, respectively.
The upper end surfaces of the front template 23 and the rear template 24 are flush with the upper surface of the embedded steel plate 7 in the reinforcement cage, and after concrete pouring is carried out, the embedded steel plate 7 is just embedded in concrete, and the upper end surfaces of the embedded steel plate 7 are flush with the upper end surfaces of the concrete members.
Because the embedded steel plate 7 and the fixed steel plate 4 in the steel reinforcement framework have height differences, foundation bolts 5 are connected between the embedded steel plate 7 and the fixed steel plate, and the supporting rods 6 need to position and support the fixed steel plate 4 through the positioning grooves 61, the height positions of the positioning grooves 61 need to have a certain relation with the positions of the embedded steel plate 7. In the present embodiment, the vertical height difference between the lower end surface of the positioning groove 61 and the upper end surface of the front form 23 is equal to the vertical height difference between the lower end surface of the inner fixed steel sheet 4 of the reinforcing cage and the upper end surface of the pre-buried steel sheet 7.
In the steel reinforcement framework, the lower end and the upper end of the anchor bolt 5 are respectively positioned through the embedded steel plate 7 and the fixed steel plate 4, and as the fixed steel plate 4 is required to be dismantled at the end of construction, only the anchor bolt 5 and the embedded steel plate 7 are left, so that the upper end of the anchor bolt 5 still keeps certain positioning precision, in the embodiment, the distance between the outer side surfaces of the two support rods 6 is equal to the distance between the inner side surfaces of the two rows of anchor bolts 5 in the steel reinforcement framework, and the support rods 6 can limit the displacement of the anchor bolts 5 in one direction. Meanwhile, friction force generated after the two are contacted can also well limit the tendency that the steel frame framework drives the support rods 6 to move in the pouring process.
