Description
Technical Field
The utility model belongs to the technical field of bridge safety construction, a integral safe construction platform suitable for bridge double-column is pour in step is related to.
Background
The high altitude construction can not be avoided in bridge stand construction, only lean on "safe three treasures" traditional safety protection measure to have been forbidden strictly, some construction platform of buildding temporarily because the stress structure is scientific unreasonable, it is too crude or flow in the form and deal with at will, there is great potential safety hazard, also do not accord with current construction safety and standardized construction requirement, consequently, need a design simply, convenient and fast, more firm bridge safety construction platform, improve the construction safety and the efficiency of construction of bridge stand.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an integral safe construction platform suitable for bridge double-column is pour in step makes it solve the safety guarantee problem of high altitude construction personnel in the work progress, makes operation personnel operation, walking and the interim very safe and convenient of having a rest, also improves efficiency of construction and engineering quality simultaneously.
The utility model adopts the following technical scheme for accomplishing the above purpose:
an integral safety construction platform suitable for synchronously pouring double upright posts of a bridge is provided with two platform main beams which are arranged in parallel; two ends of the two platform main beams are respectively and fixedly connected with the annular bearing flange; a grid frame is arranged between the two platform main beams and the two annular bearing flanges; two ends of the two platform main beams are provided with auxiliary frames for supporting the platform main beams; the auxiliary frame is fixed on the corresponding annular bearing flange; the platform main beam, the auxiliary frame and the grid frame form a platform frame together; a bamboo plywood forming a safe walking channel is laid on the top surface of the platform frame; and a protective fence is welded on the periphery of the platform frame.
The platform girder is I-shaped steel.
The protection fence is of a structure with two wide ends and a narrow middle part, and a wooden skirting board is arranged on the periphery of the bottom of the protection fence to prevent objects from falling from high altitude.
The utility model provides an integral safe construction platform suitable for bridge double-column synchronous pouring, through the above-mentioned structural design, can bear certain load atress requirement, improved whole support and protective capacities, provide convenient and safe and reliable's construction operation platform for the high altitude construction personnel; the integral safe construction platform of pier double-column is integrally processed in advance, the integral frame welded structure is not detachable, and the integral hoisting is positioned on the bearing surface at the top end of the column mould during use and is effectively and safely fixed.

Detailed Description
The invention will be described in detail with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1, the structure size (length × width) of the pier double-column integral type safe construction platform of the utility model meets the half-width bridge of 12.75 meters and the construction requirements of single-row double pier columns according to the design of a highway bidirectional four-lane separated bridge, namely meets the requirements of round columns with the diameters of pier columns of 1.8 meters, 2.0 meters and 2.2 meters and two structural forms of 6.80 meters and 7.30 meters of the center distance of the pier columns in the same row; and the diameter and the distance between the pier columns required by the drawing are subjected to matching design and stress checking calculation, so that the requirement of safe bearing and stress is met. The following further describes the installation scheme and the attention points of the present invention by means of the detailed description.
1. The main beam 1 of the pier double-column integral type safe construction platform shown in the figure 1 is formed by adopting two I-shaped steel with through length and no joint I12, and reinforcing detailed connection and support are formed by welding [12# channel steel auxiliary frames 2 and threaded reinforcing steel bar grids 3 with the diameter of 25mm to form a platform frame, a bamboo plywood is paved on the top surface of the platform frame to provide a safe walking platform and a channel, square steel with the length of 4cm multiplied by 6cm is welded on the periphery to form a protective fence 4, the height of the fence is 1.2m, the column spacing is 0.25cm, and a wooden skirting board 5 is arranged on the periphery of the fence bottom which is 20cm higher than the platform surface to prevent high-altitude falling objects. The integral type operation platform and the protection system are formed.
2. The integral safe construction platform of pier double-column, I12I-steel girder 1 is put on the annular bearing flange 6 of stand template top to adopt track mounting 7 to carry out spacing fixed, the top of the top section of each set of stand template designs the annular flange bearing surface, the annular flange bearing surface width is 30cm, and flange bottom adopts 10mm thick stiffening steel plate 8 (the circumferential interval is 50 cm) to weld in the post template outside, in order to increase the atress area and improve the bearing capacity.
3. According to the pier double-upright-column integral type safety construction platform, before hoisting, column molds must be adjusted in position according to requirements, effective fixation is carried out by adopting a steel wire rope symmetrical oblique pulling mode, and the column molds are required to have bearing capacity integrally. When the pier double-upright-column integral type safety construction platform is hoisted, hoisting points must be fixed on bearing beams, four-point symmetrical and stable hoisting is carried out by adopting steel wire ropes, and hoisting by hanging ropes at other parts is strictly forbidden.
4. The integral safety construction platform with the double upright columns for the bridge pier needs to consider the stability of the upright column templates and the platform when pouring the concrete of the pier columns, adopts symmetrical pouring construction, strictly prohibits a single pier column from being continuously poured to the top surface and then pours another pier column, and ensures that the displacement and deformation caused by unbalanced stress are avoided in the construction process.
5. The integral safe construction platform of pier double-column, after the stand pouring operation is accomplished, wholly hang and unload and keep flat on level firm temporary storage place to multiple spot even support pad, strictly forbid handstand or side stand and place, strictly forbid to place on unstable holding surface or uneven support atress leads to warping, the construction platform regularly carries out safety inspection and facility maintenance, in order to guarantee continuous use safety.
