Abstract
The utility model discloses a pre-buried steel plate localizer for a bridge padstone. Two longitudinal beams (2) and two cross beams (3) which form a #-shaped frame and tightened by connecting bolts (4) are arranged above a padstone pre-buried steel plate (1), positioning bolts (5) are connected between the longitudinal beams (2), lower limiting devices (6) are hung on the longitudinal beams (2) and connected with four corners of the padstone pre-buried steel plate (1), and fixing and adjusting bolts (7) are connected to the outer ends of the longitudinal beams (2); and upper limiting bolts (8) are connected to the cross beams (3). The widths of the longitudinal beams can be adjusted through the positioning bolts, and through the fixing and adjusting bolts, the longitudinal beams are fixed to a capping beam template below and planimetric position and elevation of the padstone pre-buried steel plate are adjusted. The lower limiting devices are used for limiting the sinking of the padstone pre-buried steel plate, and the upper limiting bolts are used for limiting the ascent of the padstone pre-buried steel plate. After concrete pouring of a capping beam at the padstone is finished, bridge padstone steel bars and the pre-buried steel plate are promptly installed and fixed through the localizer, and when the planimetric position and elevation of the padstone pre-buried steel plate are adjusted accurately, a padstone template is erected; before the prehardening of capping beam concrete, padstone concrete is poured; and when padstone concrete pouring is finished, the upper limiting bolts and the lower limiting devices can be loosened and then dismantled and cleaned for next padstone concrete construction. The localizer can achieve the purpose that the capping beam concrete and the padstone concrete are poured at one stage, so that the capping beam concrete and the padstone concrete are integrated, which improves the quality and durableness of the padstone concrete.
Description
Technical field
The utility model belongs to locator for building, specifically the used locator of road bridge steel concrete bent cap pinner construction pre-embedded steel slab.
Background technology
Steel concrete bent cap and pinner are a kind of foundation structure forms that the high-grade highway bridge generally adopts.In the prior art, generally be to build bent cap earlier, second stage concrete is built pinner again.Its operating principle is: build the bent cap concrete, and pre-buried pinner steel plate and reinforcing bar thereof, when treating that the bent cap concrete strength satisfies the second stage concrete construction requirement, the cutter hair is disposed pinner place bent cap concrete, builds the pinner concrete.The deficiency of its existence is: 1, because of being full of reinforcing bar in its pinner concrete cross section, and its end face is welded with the pinner pre-embedded steel slab, and pinner place bent cap concrete chisel hair is difficult to realize, causes pinner and two phase of bent cap concrete can not effectively become one; 2, in a single day the pinner pre-embedded steel slab plane coordinates occurs and absolute altitude is defective, disposes very difficulty, causes pinner pre-embedded steel slab absolute altitude qualification rate low.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of bridge pinner pre-embedded steel slab locator is provided, and has realized that bent cap, pinner concrete first phase build, and result of use is good.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model comprises: the pinner pre-embedded steel slab, it is characterized in that: above the pinner pre-embedded steel slab, be provided with longeron, crossbeam, longeron, crossbeam are respectively two, the two intersects formation well cabinet frame and fastening by connecting bolt in length and breadth, be connected with positioning bolt between two longerons, be hung with lower retainer and pinner pre-embedded steel slab on longeron four jiaos are connected, and the outer end activity of longeron is connected with the secured adjusted bolt; The movable upper limit bolt that is connected with corresponding to the pinner pre-embedded steel slab on the crossbeam.
The utility model is taked technique scheme, has following beneficial effect: the intersecting parallels locating rack that the utility model adopts longeron, crossbeam to form, regulate longeron width and accurate fixing longeron position by positioning bolt, by connecting bolt that longeron, crossbeam is fastening.By the secured adjusted bolt longeron is fixed on the bent cap template of below, adjusts pinner pre-embedded steel slab plan-position and absolute altitude.With the lower retainer pinner pre-embedded steel slab of slinging, restriction pinner pre-embedded steel slab sinks.Float with upper limit spiral limits pre-embedded steel slab.After treating that the bent cap concreting of pinner place is finished, bridge pinner reinforcing bar, pre-embedded steel slab are installed at once, and are fixed with locator, treat that pinner pre-embedded steel slab plan-position and absolute altitude are accurately adjusted after, a upright pinner template; Before the bent cap concrete initial set, build the pinner concrete.After treating that pinner concreting is finished, can become flexible pinner pre-embedded steel slab upper limit spiral and lower retainer, be used for next pinner concrete construction after the dismounting cleaning.The utility model can satisfy the purpose that bent cap, pinner concrete first phase are built, and makes its one-tenth as a whole, has improved pinner quality of concrete and durability.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the utility model plan structure sketch.
Fig. 2 is the utility model master TV structure sketch.
Mark among the figure: 1-pinner pre-embedded steel slab, 2-longeron, 3-crossbeam, 4-connecting bolt, 5-positioning bolt, 6-lower retainer, 7-secured adjusted bolt, 8-upper limit bolt, 9-long slot bore, the interim hanger of 10-, 11-length adjustment device.
The specific embodiment
By Fig. 1, shown in Figure 2, the utility model comprises: pinner pre-embedded steel slab 1, longeron 2, crossbeam 3.Longeron 2, crossbeam 3 are respectively two, be positioned at the top of pinner pre-embedded steel slab 1, longeron 2, crossbeam 3 intersect formation well cabinet frame and fastening by connecting bolt 4 in length and breadth, between two longerons 2, be connected with positioning bolt 5, be hung with lower retainer 6 and pinner pre-embedded steel slab 1 on longeron 2 four jiaos are connected, and the outer end activity of longeron 2 is connected with secured adjusted bolt 7; The movable upper limit bolt 8 that is connected with corresponding to pinner pre-embedded steel slab 1 on the crossbeam 3.
On crossbeam 3, offer the long slot bore 9 that is used to regulate width corresponding to connecting bolt 4.
Four jiaos of pinner pre-embedded steel slab 1 are provided with interim hanger 10, are used to connect lower retainer 6, and lower retainer 6 is provided with length adjustment device 11, is used to limit pinner pre-embedded steel slab 1.
Before the pinner concrete strength satisfies construction requirement, plate-girder and installs, the interim hanger of pinner pre-embedded steel slab is cut away, polishes and get final product.
The utility model is applied in the construction of a bridge of Coast Expressway, and effect is fine.Begin to adopt traditional handicraft, have 30% pinner pre-embedded steel slab disadvantages such as injustice, sinking, come-up to occur.After using the utility model, disadvantages such as injustice, sinking, come-up do not appear in the pinner pre-embedded steel slab, have obtained the good effect of qualification rate 100%.After to be used for many highway bridge pinner project benefits remarkable.
