Description
Technical Field
The utility model belongs to building bridge engineering base stone anchor bolt hole construction accuracy control field specifically is an aerify type pineapple line rubber stick anchor bolt hole accurate positioning and pour forming die.
Background
For years, in the construction process of anchor bolt holes of highway, railway and municipal bridge cushion stones in national building engineering, the positioning precision of the anchor bolt holes is poor, so that the diameters of the anchor bolt holes are enlarged by 4-6 cm compared with the design in site, PVC plastic pipes are sleeved in the anchor bolt holes to serve as temporary molds of the cushion stone reserved anchor bolt holes, the PVC pipes in the holes are chiseled before beam erecting, and then the hole walls are further chiseled. The positions of some anchor bolt holes are subjected to drilling again at the designed positions due to the fact that curve pre-deviation values are not considered or construction positioning errors are too large. Due to various factors, the pore volume of the anchor bolt is larger and generally exceeds 30-50% of the designed volume, and the excessive consumption of grouting material is very large.
The main reasons for large diameter and inaccurate position of the anchor bolt hole are that the cushion stone template is made of a bamboo plywood, so that the positioning precision is low, the rigidity of the template is poor, and the anchor bolt hole PVC pipe cannot be positioned by using the positioned cushion stone template. In addition, the reinforcing steel bars at the position of the anchor bolt hole are cut off again after the reinforcing steel bars of the cushion are bound, the randomness of the cutting-off position of the reinforcing steel bars is too strong, the cutting-off shape is not round, and the cutting-off range is large. Because the control precision of the reserved position of the anchor bolt hole is low, the reserved hole can surround the designed position of the anchor bolt hole only by arranging a large-diameter PVC pipe. Some reserved anchor bolt hole sites have great difference from the design, the plane position and the verticality do not meet the requirements, and finally secondary drilling is carried out.
The in-process construction cost increases including three aspect, firstly chisels the expense of removing downthehole PVC pipe and pore wall chisel hair, and present labour cost is higher, and this process has the problem that operating space is little, the chisel is removed the degree of difficulty and is big, the efficiency is low. Secondly, the cost of re-drilling with large position deviation and unqualified verticality comprises labor cost and the matching cost of a crane, and the cost of processing one pier exceeds 2000 yuan. Thirdly, the cost of the over-consumption grouting material is high, the density of the grouting material is 2.2, and the price of the grouting material per ton is 2000-3000 yuan. If the project management is not strict, the excess of the grouting material can reach about 50%, and the increased construction cost can reach 100-200 ten thousand yuan. Therefore, if the construction control of a project mainly based on a bridge is not good in the aspect of anchor bolt holes, the loss of construction benefits can reach millions of yuan.
Disclosure of Invention
The utility model discloses a solve above-mentioned problem, provide an aerify type pineapple line rubber stick anchor bolt hole accurate positioning and pour forming die.
The utility model adopts the following technical proposal: an inflatable pineapple grain rubber rod anchor bolt hole accurate positioning and pouring forming die comprises a cushion steel template, at least one bracket is fixed on the cushion steel template, the support include that the symmetry sets up the support main beam in both sides, be connected with two piece upper and lower vertical guide beams between the main beam, be provided with longeron end uide bushing on the vertical guide beam, connect horizontal guide beam between the longeron end uide bushing of two piece upper and lower vertical guide beams, set up the guide beam scale sign on the horizontal guide beam, the cover has the uide bushing on the crossbeam on the horizontal guide beam, open at the uide bushing middle part on the crossbeam has the scale window, uide bushing side fixed mounting has the arc wall support on the crossbeam, install the arc wall on the arc wall support, the arc wall both ends are connected through the arc wall buckle respectively with between the arc wall support, install inflatable pineapple line rubber stick between arc wall and the arc wall buckle, inflatable line rubber stick can wind arc wall pivot rotation.
Furthermore, the combined end of the inflatable pineapple-shaped rubber rod and the arc-shaped groove is a fixed end which is of an unexpanded structure, and an air valve is arranged on the fixed end.

Compared with the prior art, the utility model discloses following beneficial effect has:
1. the whole set of die is customized, and the template steel of the cushion stone has large rigidity, small deformation and high turnover rate. At present most base stone template adopt be bamboo plywood or wooden multiply wood, the turnover number of times 1~3 times to bamboo plywood class template rigidity is little, warp big, still needs back lining square timber to consolidate, and the bulk rigidity is less than the steel form, dares not fully to vibrate when pouring, and the template warp greatly, easily runs the mould, and finished product base stone surface quality also is not as effectual as the steel form. The steel template has the advantages of high turnover utilization rate and low comprehensive cost, and saves natural resources such as wood.
2. The support is fixed with the template, and the overall stability and rigidity of the die are improved. 4 anchor bolt hole inflation type pineapple grain rubber sticks are fixed on a double portal frame, the support is fixed with the template after the position is determined, the integral rigidity and stability of the support and the steel template are improved, so that the 4 rubber sticks fixed on the support cannot be pushed to incline or walk in the concrete pouring process, and the stability and hole position precision of the anchor bolt hole rubber sticks are greatly improved.
3. The anchor bolt hole inflatable pineapple-shaped rubber rod is fixed on the support, and scale marks are arranged on the longitudinal and transverse guide beams, so that bidirectional adjustment and accurate positioning can be realized. 4 anchor bolt hole rubber rods of a support are fixed on a set of support, sizes of the anchor bolt holes are different due to different support types, and the 4 anchor bolt holes in the portal frame are adjustable in bidirectional distance and provided with fixing screws, so that accurate positioning is achieved.
4. The inflatable pineapple-shaped rubber rod expands uniformly, and the anchor bolt holes are formed beautifully. Every 4 rubber sticks can set up the valve respectively and also can set up one set of one in four aerifys the linker, aerifys and adopts the aerating device who takes the manometer, aerifys according to design pressure, ensures that atmospheric pressure is unanimous, the inflation is even, reaches ideal pore-forming effect.
5. The pineapple grain inflatable rubber rod is adopted, PVC pipe chiseling and roughening procedures of a conventional anchor bolt hole are reduced, the anchor bolt hole can be controlled according to the designed minimum diameter, grouting materials are saved, and construction cost is reduced. The anchor bolt holes are reserved in the pineapple grain inflatable rubber rods, the rubber rods are inflated and expanded before the stone concrete is poured, the concave-convex height difference of the pineapple grains is about 2mm, air is discharged after the poured concrete is initially set, concave-convex grains are naturally formed in the hole walls, and the process problem that PVC pipes are chiseled off and chiseling is difficult to dry is well solved. And the most important is that the hole diameter of the anchor bolt is not amplified due to accurate positioning, so that the excess consumption of the grouting material is less, the production cost can be obviously saved, and the benefit loss is reduced.
