Description

An auxiliary device for steel bar installation for high bridge pier construction

technical field

The utility model relates to the field of civil construction, in particular to an auxiliary device for installing steel bars used in the construction of reinforced concrete cast-in-place structures for high bridge piers.

Background technique

In concrete construction, especially in the construction of long-span bridges with high piers, there are many deficiencies in the installation process of steel bars. High-pier long-span bridges are very difficult in transportation, construction and safety management due to pier height, large terrain fluctuations, and poor terrain conditions. In addition, for design reasons, thin-walled flexible piers or hollow pier structures are used, corresponding to the model of the main reinforcement If the spacing is large and the spacing is small, it will be very difficult to transport, hoist, align and connect, bind and shape, and install steel bars. In the prior art, tower cranes are generally used to hoist the steel bars to the working platform on the top of the pier, and the main bars are erected, hoisted, aligned, and temporarily connected to the joints one by one manually, and the positioning is assisted by the working platform, and then the main bars are connected to the joints. After it is in place, adjust the main reinforcement spacing, straightness, positioning, installation of structural reinforcement and other processes; because the main reinforcement is heavy (large model), and the stability of the working platform is limited (it is a temporary structure), the safety risk of people working at heights is prominent. Manual lifting is very difficult, resulting in low efficiency, slow speed, and high cost of steel bar installation. In addition, after the structural steel frame is installed, due to limited temporary support conditions, it is difficult to control the verticality of the main steel frame structure. To sum up, the existing technology has disadvantages such as high labor intensity of manual operation, large number of construction personnel, prominent safety risks of high-altitude operations, difficult construction quality assurance, long cycle construction period, and high operating costs.

detailed description

The utility model will be further described in detail below in conjunction with the examples, but the implementation of the utility model is not limited thereto.

Example 1:

As shown in Figures 1 and 2, an auxiliary device for installing steel bars for the construction of high bridge piers includes two channel steels 1 with the same specifications, and the bottoms of the two channel steels 1 are fixed against each other so that the cross section is The "H"-shaped integrated structure is intermittently provided with at least one through groove 3 at the bottom of the channel steel 1, and the straight thread sleeve 2 is arranged on the through groove 3. The choice of two channel steels 1 is mainly due to the consideration that lifting multiple 9m steel bars at the same time will cause deformation of one channel steel 1, and the two channel steels 1 can be fixed in some places by facing back to increase the bending resistance of channel steel 1. , to ensure the verticality of the hanging steel bars, easy to install. And here the channel steel 1 is not limited to the welding method, and can also be connected by bolts or other methods; the channel steel 1 is also provided with a through hole 5 that can be hoisted horizontally by a rope on the channel steel 1, and the through hole 5 is used for Through the wire rope or the hook, the through hole 5 can be slightly offset to the center of the channel steel 1, so as to avoid the through hole 5 being too close to the edge of the channel steel 1 to cause the through hole 5 to bear load and deform.

Example 2

The through groove 3 is arranged on the vertical line of the short side of the bottom of the channel steel 1 and is consistent with the direction of the vertical line. There are 10 to 20 through grooves 3, and the distance between the through grooves 3 is 30mm to 70mm; the through groove 3 The distance between them is 50mm; during the construction process, the distance required for the main reinforcement in different places is inconsistent. In order to ensure that the main rib spacing can be adjusted and the main ribs of different sizes can be selected, the length of the channel 3 is 60-140 mm, and the width of the channel 3 is 20 mm-40 mm; preferably, the length of the channel 3 is 100 mm, and the width of the channel 3 is 100 mm. The channel 3 can be set as much as possible according to the length of the channel steel 1; at present, in the construction of roads and bridges, the main reinforcement is mostly used as 32mm, and the channel 3 with a width of 33mm is set here so that the main reinforcement can just pass through the channel 3 , and the outer diameter of the straight threaded sleeve 2 adapted to the 33mm main reinforcement is obviously larger than 33mm, so that the straight threaded sleeve 2 is hung on the two ends of the long side of the through groove 3, so that the steel cable is lifted by the tower crane, and then the Lift up the whole device, the state shown in Figure 3.

Example 3

The side of the through groove 3 is also provided with a scale line 4 consistent with the length direction of the channel steel 1; wherein the scale line 4 can be continuously arranged along the length direction of the channel steel 1; the scale line 4 can also be along the length of the channel steel 1 The direction is intermittently set only on the side of the through groove 3, and each segment of the scale line 4 is consistent with the length of each long side of the through groove 3. During the construction process, different areas have different requirements for the spacing of the main reinforcement. When the spacing needs to be replaced, the spacing can be recalibrated according to the scale line 4 under the building, and the straight thread sleeve 2 that is connected to the steel bar can be adjusted. to the corresponding position, which facilitates the work of construction personnel above the building.

In summary, the specific working process of the utility model is as follows: first, under the construction area, according to the spacing of the main reinforcement, refer to the scale line 4 on the channel steel 1, pass the main reinforcement through the through groove 3 and screw on the straight thread Sleeve 2, and then the steel wire rope or hook passing through the slot 3 is lifted by the tower crane to lift the whole device together with the steel bar. When it reaches the position, connect the lower end of the steel bar with the straight thread sleeve 2 below, and then remove the device. The straight thread sleeve 2 is taken off from the steel bar, and the straight thread sleeve 2 taken off is screwed on the steel bar, so that the installation of the next group of steel bars can be carried out. When changing the spacing of the main reinforcement, it is very convenient to re-calibrate and fix the position of the reinforcement through the scale line 4 on the device under the construction area.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification or equivalent change made to the above embodiments according to the technical essence of the utility model falls within the scope of the present utility model.
