Abstract
The utility model relates to a kind of end templates for the construction of Thin-wall Hollow Pier pier top solid-section, precast slab including a rectangle, it is provided in precast slab and is intersected the framework of steel reinforcement connected by longitudinal reinforcement and transverse steel, vertical reinforcement is also connected in each intersection of longitudinal reinforcement and transverse steel, the end of longitudinal reinforcement and transverse steel protrudes from precast slab periphery certain length, and the upper end of vertical reinforcement protrudes from precast concrete plate top surface certain altitude.The utility model directly overlays at the hollow section of pier top hollow section top, is linked together completely with solid section concrete, without individually setting up and dismantling end template.
Description
Technical field
The utility model relates to bridge Wall Voided Pier construction fields, and in particular to one kind is used for Thin-wall Hollow Pier pier top
The end template of solid-section construction.
Background technique
Major part Main Pier of Bridges is both designed as thin-walled hollow structure at present, this bridge pier have the rigidity of structure and intensity it is good,
From heavy and light, the feature that section modulus is big and area of section is small.As shown in Figure 1, the main body of Thin-wall Hollow Pier 1 is hollow section 2, pier
Top is solid-section 3, and the difficult point in construction is that the end template of pier top solid-section 3 is constructed.Most of pier top hollow section is to become to cut
Face setting, construct pier top solid-section when, if simply hollow section top cover a cover board, not can guarantee cover board with it is solid
Section concrete connection is integrated, and can be seriously affected solid-section quality, be caused major safety risks；Therefore usually construction method be
The good built-in fitting of hollow section inner wall variable cross-section apical position pre-plugged, then when constructing pier top solid-section process, utilization is pre-buried
Part sets up solid-section end template by way of welding shape steel bracket.When constructing hollow section, it is arranged to go out on Dun Bi in advance
Enter the constructor hole inside hollow section, after the completion of solid-section pours, construction personnel enters constructor hole will be inside hollow section
Shape steel bracket and end template take out.But constructor hole, which is arranged, can have an impact to the overall structure of hollow thin-walled high pier, and enter construction
There is certain security risk when the removal bracket of people hole；If being not provided with constructor hole, the built-in fitting in hollow section can not be taken out, only
It can for good and all be retained in inside pier stud, not only cause waste of material, also cause hidden danger of quality to pier stud internal structure.
Summary of the invention
The purpose of the utility model is to provide a kind of end templates for the construction of Thin-wall Hollow Pier pier top solid-section, do not have to
Built-in fitting and welding shape steel bracket is arranged in pier stud hollow section top inner wall, and no matter whether hollow thin-walled high pier considers that constructor is arranged
Construction cost is saved in the case where not influencing main structure in hole, guarantees pier stud construction quality.
Technical scheme is as follows:
A kind of end template for the construction of Thin-wall Hollow Pier pier top solid-section, the end template include the prefabricated mixed of a rectangle
Concrete board is provided in precast slab and is intersected the framework of steel reinforcement connected by longitudinal reinforcement and transverse steel, special
Sign is: being also connected with vertical reinforcement, the longitudinal reinforcement and transverse direction in each intersection of longitudinal reinforcement and transverse steel
The end of reinforcing bar protrudes from precast slab periphery certain length, and the upper end of the vertical reinforcement protrudes from precast slab
Top surface certain altitude.
The utility model, which is used, is directly placed at pier stud hollow section top with the concrete slab of label with pier top solid-section,
The end template that entire solid-section pours is served as, horizontal Vertical bar connection is then carried out, solid section concrete is poured, after the completion of construction
End template is integrally formed with solid section concrete, it is no longer necessary to remove end template, solid-section is without again by setting up fashioned iron branch
The mode of frame support end template is constructed, and additional influence is not caused to pier stud, reduces construction cost, accelerates construction
Progress also avoids the security risk of later period disassembly end template.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of Thin-wall Hollow Pier；
Fig. 2 is that the reinforcing bar of the utility model lays plan view；
Fig. 3 is that the reinforcing bar of the utility model lays elevation；
Fig. 4 is the status diagram that the utility model is used for the construction of Thin-wall Hollow Pier solid-section.
Specific embodiment
As shown in Figure 2 and Figure 3, the utility model includes the precast slab 4 of a rectangle, setting in precast slab 4
Have and intersected the framework of steel reinforcement connected by longitudinal reinforcement 5 and transverse steel 6, in each of longitudinal reinforcement 5 and transverse steel 6
Intersection is also connected with vertical reinforcement 7, and the end of the longitudinal reinforcement 5 and transverse steel 6 protrudes from precast slab 4 weeks
Side certain length, the upper end of the vertical reinforcement 7 protrude from 4 top surface certain altitude of precast slab.
When the utility model is constructed for Thin-wall Hollow Pier pier top solid-section, the laying spacing of longitudinal reinforcement, transverse steel,
Completely the same with the longitudinal and transverse rebar design spacing of pier top solid-section, the length for protruding from concrete slab periphery will be able to satisfy
It is connect with the longitudinal and transverse reinforcing bar of solid-section；The height of vertical reinforcement is consistent with pier top solid-section vertical bar height；Precast slab mixes
Solidifying soil label is identical with the concrete grade of solid-section, is one so that end template can link completely with solid section concrete
Body.
The size of precast slab, generally will be by its vertically and horizontally size setting depending on hollow section top cross-section size
It is advisable to be respectively greater than the vertically and horizontally size 0.2m of hollow section at the top of hollow section.Such as in one specific embodiment of the utility model
In, the hollow section at the top of bridge pier hollow section is having a size of 2.4 × 2.4m, then the concrete slab of the utility model is designed and sized to
2.6×2.6m。
As shown in figure 4, being poured when the utility model is constructed for Thin-wall Hollow Pier pier top solid-section in bridge pier hollow section 2
After the completion, 4 surrounding of the precast slab of the utility model and top surface dabbing are handled, is then lifted into hollow section 2 with loop wheel machine
Hollow section section is completely covered at top.Then lay pier top solid-section reinforcing bar, and by the vertically and horizontally reinforcing bar of solid-section respectively with
The vertical, horizontal reinforcement welding on the utility model periphery connects.The concrete for starting to pour solid-section 3 pours sequence using first four
Mid way after week after concrete surface integrally covers prefabricated bed die plate top surface, then carries out center concreting.Entirely
After the completion of solid-section concreting, the utility model and solid section concrete go completely into one.
