Description

A kind of bridge pad pinner anchor hole hole-forming device

Technical field

The utility model relates to bridge construction fields, and in particular to one kind is used for bridge pad pinner anchor hole pore-forming Device.

Background technique

Currently, bridge pad pinner anchor hole pore-forming mainly uses pvc pipe as anchor hole pore-forming support mode, bottom is used Adhesive tape seals, the flexible materials such as inside filling geotextiles, positioning is fixed outside tube body, in this, as anchor hole pore-forming Mold.But pvc pipe rigidity is small, easily-deformable, and anchor hole is caused to protrude or be recessed.Tube body is that flexible material blocks up and down, easily makes to prop up Bottom pours in concrete when seat cushion stone concrete is constructed, and causes anchor bolt hole depth inadequate, and is guaranteeing design anchor bolt hole depth Under the premise of take a lot of work, be time-consuming when handling the concrete poured in.Individual tube body stationary positioned effect is poor, easily causes hole location deflection, weight It is new to repair hole location time-consuming, labour-consuming；Bearing pad stone anchor hole pore-forming rear mold needs to remove, and tube body cannot be removed integrally, be broken into more Fritter takes out, and removes difficulty, and can not reuse, causes increased costs.

Utility model content

The technical problem to be solved by the present invention is to overcome the shortcomings of existing technology, provide a kind of for bridge Bearing pad stone anchor hole hole-forming device, structure is simple, easy to make, accurate at hole site, facilitates taking-up, is convenient for constructing operation, And can reuse, it is practical, and greatly saved construction cost.

To reach above-mentioned technical purpose, bridge pad pinner anchor hole hole-forming device described in the utility model, including one The closed tube body of upper and lower port；

Preferably, the tube body is a kind of tube body that steel plate rolls, by steel plate welded closure at the tube body upper and lower port.

Preferably, multiple spacer bars are provided at the upper port of the tube body.

Preferably, one end of the spacer bar is welded on tube body upper port edge, and the other end and bearing pad stone reinforcing bar are solid Fixed connection.

Preferably, the equal length of each spacer bar, and spacing is equal between adjacent positioned reinforcing bar.

Preferably, official's body of the tube body is provided with multiple fixture blocks.

Preferably, there are two the fixture blocks, the two sides of tube body are symmetrically set.

Preferably, the fixture block is positioned close at tube body upper port, is greater than anchor bolt with the vertical range of bottom of the pipe mouth The depth in hole.

Preferably, the upper port of the tube body is provided with handling frame.

Preferably, the outer surface of the tube body is coated with release agent.

Generated beneficial effect is by adopting the above technical scheme：Closed tube with spacer bar can be in anchor bolt Fixed hole position in the pore forming process of hole avoids pouring in when concreting into hole and causes anchor hole in irregular shape.Setting removes Fixture block and handling frame make the removal operation of hole-forming device become easy, fast.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it can also be obtained according to these attached drawings other attached drawings.

Fig. 1 is bridge pad pinner keyhole hole-forming device pipe structure schematic diagram.

Fig. 2 is bridge pad pinner keyhole hole-forming device floor map.

Wherein：1- tube body, 2- spacer bar, 3- fixture block, 4- lift frame.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

With reference to Fig. 1 and Fig. 2, a kind of bridge pad pinner keyhole hole-forming device provided in this embodiment.As shown in Figure 1, should Device rolls into tube body using the steel plate with a thickness of 3 millimeters and Jing Guo preservative treatment, and the upper port and lower port of tube body 1 use steel The weld of plate welded closure, steel plate and tube body 1 polishes smooth, and uses the preceding outer surface coating release agent in tube body 1.Using this Tube body 1 when bearing pad stone casting concrete, can provide enough support stiffness in anchor hole pore-forming operation for anchor hole pore-forming, Effectively avoid extruding force when concreting from spending leads to pore-forming die deformation due to causes anchor hole irregular greatly, ensure that Hole quality.And about 1 tube body blocks, and effectively prevent pouring in concrete from tube body upper and lower port when concreting, avoid Cleaning work in unnecessary hole.It is 12 millimeters and equal length that the edge of 1 upper port of tube body, which is uniformly arranged 4 diameters, Spacer bar 2, in pore forming process, one end of every spacer bar 2 is welded in the on the edge of the port of tube body, the other end and branch The reinforcing bar of seat cushion stone is welded, and tube body is firmly secured at into hole site, when effectivelying prevent bearing pad stone casting concrete Tube body inclination, displacement occurs, guarantees the straight cis degree of anchor hole, avoids unnecessary hole location amendment operation.As shown in Fig. 2, tube body Pipe shaft be symmetrically welded two 10 millimeters of thick steel plates as fixture blocks 3 are removed, it is 10 that a diameter is provided at the upper port of tube body 1 Frame is lifted made of the round steel of millimeter.After the completion of anchor hole pore-forming, spacer bar 2 and the weld of bearing pad stone are cut It cuts, two spanners is used to block the impetus for removing fixture block 3 as rotation tube body 1, rotation tube body 1 disengages it from the packet of concrete It wraps up in, hole-forming device is taken out by lifting frame, it is convenient, fast to remove process, and the hole-forming device can be utilized repeatedly, is effectively controlled This is made, saves resource, there is biggish popularizing value.

It should be understood that the particular order or level of the step of during disclosed are the examples of illustrative methods.Based on setting Count preference, it should be appreciated that in the process the step of particular order or level can be in the feelings for the protection scope for not departing from the disclosure It is rearranged under condition.Appended claim to a method is not illustratively sequentially to give the element of various steps, and not It is to be limited to the particular order or level.
