Abstract
A device used for preventing a form board from grout leakage during precasting of beams and plates belongs to the technical field of bridge engineering. The device is characterized in that channel steels are respectively arranged at the parts where a baseplate, a web plate, wing plates and a top plate form board are spliced, and rubber strips are padded in the channel steels; a modular form rubberstrip at a flange plate edge is used for padding the channel steel, and rubber sawteeth are used to mesh and clamp a reinforcement bar. The device has the beneficial effects that the anti-grout leakage technology of using rubber pipes to pad channel steels is adopted, the seams between the side dies and the bottom die are tight without grout leakage, thereby effectively preventing grout leakage at the footing, the construction process is simple, the installation and the form removal by workers are convenient, only simple reinforcement is required, the process of blocking form board gaps is saved, and the precasting of the box girders is greatly enhanced. By utilizing the upper and lower meshing of the sawtooth rubber, reinforcement bar pore passages are reserved, not only no grout leakagefrom the pre-buried reinforcement bars can be guaranteed, but also the position of the pre-buried reinforcement bars can be guaranteed; thin rubber strips are utilized to be served as a spacer between form boards, not only grout leakage can be prevented, but also the form boards can be protected.
Description
Technical field
The utility model belongs to technical field of bridge engineering.
Background technology:
In carrying out the beam prefabricated work progress of case in the past, spillage takes place at the position of base plate and web, wing plate and roof plate template splicing and the notch place that reinforcing bar stretches out outside the template in discovery easily, even employing sponge adhesive tape is stopped up the slit between the template, still can not reach anti-spillage effect.Concrete splices imprecision and reinforcing bar and template junction from template and spills, part condenses into piece attached to Liang Tishang, the spillage at wing plate position even past dirty along the beam body, pollute the beam body, greatly influence the presentation quality of prefabricated case beam, employed closing seam gap material does not play anti-spillage effect.
The method of the beam prefabricated spillage of conventional treatment case is to come slit between the fully sheathed case beam forms with the sponge adhesive tape, but the sponge adhesive tape is a water-absorbing material, and material is thin soft, and cracky in the construction does not have due effect to anti-spillage; And the sponge adhesive tape is that disposable material can not be recycling, and waste of material is big.The workman will paste sponge strip repeatedly before each prefabricated, and the labour consumes greatly.Flange plate place template utilizes U shaped steel plate to do the leakproof pulp material at first, can only prevent spillage with the plug loose hemp fiber between the reinforcing bar up and down, and effect is bad, and U shaped steel plate easily produces distortion during form removal.
Summary of the invention
The purpose of this utility model is: provide a kind of precast beam to prevent template spillage device, it has solved the problem of template spillage effectively.
The technical solution of the utility model is: the position in base plate and web, wing plate and roof plate template splicing is provided with channel-section steel, filled rubber bar in the channel-section steel; Edge of a wing edges of boards modular form is clogged channel-section steel with rubber strip, grips reinforcing bar with the interlock of rubber sawtooth.
The beneficial effects of the utility model are: the anti-spillage technology that adopts rubber tube filling channel-section steel, closely connected and the spillage not of side form and bed die seam, effectively stop the footing spillage, construction technology is simple, workman's installation and form removal are convenient, only need simple the reinforcing to get final product, saved obstruction template slit operation, improve the beam prefabricated speed of case greatly.Utilize the interlock up and down of sawtooth rubber, the reserved steel bar duct had both guaranteed to guarantee the position of embedded bar again not from the embedded bar spillage; Utilize pad between TR thin rubber row culture template, not only stop spillage but also play the effect of protecting template.
Elastomeric material is bought convenient, can use repeatedly, improves the closed matereial cycle rate, saves cost.Easily the form removal easy cleaning is economic and practical.Reduce concrete unnecessary waste, reduced the beam prefabricated cost of case, improved economic benefit.

Fig. 2 is a side form side view before the ground tire cast concrete;
Fig. 3 is a side form vertical view before the ground tire cast concrete;
Fig. 4 is that the flange plate template adopts edge rubber strip top structure chart in the channel-section steel;

Fig. 6 is that the flange plate template adopts edge rubber strip upper and lower part integrated structure figure in the channel-section steel;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in Fig. 1,2 and 3,1 is that pre-buried channel-section steel, 2 is that reserving hole channel, 3 is that rubber tube, 4 is the ground tire.
Before ground tire 4 cast concretes, be connected with ground tire reinforcing bar at pre-buried channel-section steel 1 bottom welding U shaped steel muscle, and utilize pvc pipe reserving hole channel 2 before 4 cast of ground tire, the side form bottom utilizes ground tire 4 reserving hole channels 2, reinforces by Screw arbor with nut at both-ends.φ 30mm steel pipe is adopted at the side form top, wears φ 18 reinforcing bars in the steel pipe and carries out drawing.During the template assembling, rubber tube 3 is filled in 1, side form is installed then.
Shown in Fig. 4,5 and 6,5 is that channel-section steel, 6 is that rubber strip sawtooth, 7 is the reinforcing bar preformed hole.
The flange plate template adopts edge rubber strip in the channel-section steel, the inner outline that is set in rubber strip in the channel-section steel 5 and channel-section steel is identical substantially, the rubber strip that is exposed at channel-section steel outward encases channel-section steel b leg width, make rubber strip and channel-section steel facade in one plane, and exposed parts rubber strip 6 is processed into zigzag fashion, on rubber strip 6, be reserved with wet joint reinforced hole 7, fixedly lower part rubber strip and channel-section steel before colligation flange plate reinforcing bar, press from both sides rubber strip between channel-section steel plane and roof plate template, and utilize capable bolt of T and roof plate template to reinforce at the channel-section steel two ends; After the top board reinforcing bar binding is intact, be pressed into the top rubber strip, arrange out a reinforcing bar to be pressed into earlier in the reserved steel bar hole 7 before and after wanting when being pressed into, mutually meshing the upper and lower two slat gum bars of rubber strip again, tightly fasten reinforcing bar, effectively prevent the spillage phenomenon between box beam flange and the top board, solved the spillage problem of pre-buried wet seam reinforcing bar and template intersection.Because flange plate place concrete height is little, to fixedly connected between lower part flange plate and roof plate template, face down bonding two annulus outside the first half and the latter half channel-section steel utilize channel-section steel about iron wire or the bolting.
