Description
Technical field
The utility model relates to road and bridge construction field, specifically refers to a kind of chamfering formwork for road and bridge construction.
Background technology
Wedge angle is there is in concrete casting building body angle in road and bridge construction, need to build chamfering in casting process, manyly build the situation that chamfering all exists damaged and rough surface crack, corner, and traditional chamfering formwork is all the mode by being welded in template, template will be dismantled after having built, such operation is loaded down with trivial details and likely produce damage to the chamfering of having built.
Utility model content
The purpose of this utility model is to provide a kind of for the simple to operate of road and bridge construction and can not to the chamfering formwork of building chamfering and produce damage.
The utility model is achieved through the following technical solutions:
A kind of chamfering formwork for road and bridge construction, form primarily of back cord, base plate, gripper shoe, elongated steel pipe, pulling-on piece, pull bar, backing plate and steel plate for sealing water, described back cord is arranged on fender post side, elongated steel pipe transverse and longitudinal vertical interlaced form net surface structure, the wire side that gripper shoe and elongated steel pipe are formed is fixed on back cord by pulling-on piece, the wire side that gripper shoe chamfered portion and elongated steel pipe are formed is fixed on base plate by pull bar, and steel plate for sealing water is arranged on back cord top middle portion.
Further, described pulling-on piece one end is welded on back cord, and the pulling-on piece other end is by fixation steel plate and be bolted on the net surface structure of elongated steel pipe formation.
Further, described pull bar one end is welded on base plate, and the pull bar other end is by fixation steel plate and be bolted on the net surface structure of elongated steel pipe formation.
Further, described cross binding plate bottom arranges backing plate and gripper shoe is supported on base plate.
During installation, close contact between base plate and back cord and the concrete of having built, prevent concreting spillage, after base plate and back cord install location, gripper shoe is vertically close to back cord, gripper shoe lower end supports by backing plate, and the net surface structure that elongated steel pipe is formed is close in gripper shoe side, and with fixation steel plate and bolt, pulling-on piece and pull bar and said structure and base plate and back cord is fixed.The dismounting of post, beam, template die plate must treat that concrete reaches the demoulding strength of design or code requirement, column template should when concrete strength can ensure that its surface and corner angle are not damaged because of form removal, can remove, plate and beam bottom mother plate should reach 100% of design strength at beam slab concrete strength, and have cured under same condition form removal pressure testing to report, sign and issue form removal through management examination & approval and notify that rear is dismountable.During dismounting, first pull down pulling-on piece bolt, extract pulling-on piece out, reinforcing bar and gripper shoe are pulled down, afterwards stay-bolt, extract pull bar out, reinforcing bar and gripper shoe are pulled down, then will move after back cord and base plate or hang away.
Compared with prior art, the beneficial effect had is the utility model: structure is simple, easy to loading and unloading, can make each position uniform stressed of chamfering, reduces when loading and unloading the damage of watering building body.

Wherein: 1-back cord; 2-base plate; 3-gripper shoe; 4-elongated steel pipe; 5-pulling-on piece; 6-pull bar; 7-backing plate; 8-steel plate for sealing water; 9-fixation steel plate; 10-bolt.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1:
As shown in Figure 1, a kind of chamfering formwork for road and bridge construction, form primarily of back cord 1, base plate 2, gripper shoe 3, elongated steel pipe 4, pulling-on piece 5, pull bar 6, backing plate 7 and steel plate for sealing water 8, described back cord 1 is arranged on fender post side, the horizontal and vertical vertical interlaced of elongated steel pipe 4 forms net surface structure, the wire side that gripper shoe 3 and described elongated steel pipe 4 are formed is fixed on back cord 1 by pulling-on piece 5 successively, the wire side that gripper shoe 3 chamfered portion and described elongated steel pipe 4 are formed by pull bar 6 is successively fixing on a base plate 2, and steel plate for sealing water 8 is arranged on back cord 1 top middle portion.Described pulling-on piece 5 one end is welded on back cord 1, and pulling-on piece 5 other end is fixed on the net surface structure of elongated steel pipe 4 formation by fixation steel plate 9 and bolt 10.On a base plate 2, pull bar 6 other end is fixed on the net surface structure of elongated steel pipe 4 formation by fixation steel plate 9 and bolt 10 welding of described pull bar 6 one end.Described cross binding plate 3 bottom arranges backing plate 7 and gripper shoe 3 is supported on a base plate 2.
During installation, close contact between base plate and back cord and the concrete of having built, prevent concreting spillage, after base plate and back cord install location, gripper shoe is vertically close to back cord, gripper shoe lower end supports by backing plate, and the net surface structure that elongated steel pipe is formed is close in gripper shoe side, and with fixation steel plate and bolt, pulling-on piece and pull bar and said structure and base plate and back cord is fixed.Form removable should be carried out according to the regulation of matching board design, follows first to prop up and tears open afterwards, first non-weight bearing area rear load-bearing position, top-down principle.Forbid during form removal firmly to pound hard sled with sledgehammer and crowbar.During dismounting, first pull down pulling-on piece bolt, extract pulling-on piece out, reinforcing bar and gripper shoe are pulled down, afterwards stay-bolt, extract pull bar out, reinforcing bar and gripper shoe are pulled down, then will move after back cord and base plate or hang away.
The above; it is only preferred embodiment of the present utility model; not do any pro forma restriction to the utility model, every any simple modification, equivalent variations done above embodiment according to technical spirit of the present utility model, all falls within protection domain of the present utility model.
