Description

Box beam steel and wood composite template

Technical field

This patent is related to the important equipment used on municipal bridge and railroad bridge engineering, and suitable construction site is to coagulation Quality requirement is higher, beautiful after native molding component, while needs the die plate equipment of mass production concrete component.

Background technology

In science of bridge building, when pouring reinforcement concrete box beam concrete, need to use combined steel formwork or wooden model.Using group Box-like punching block, cost is big, and since steel form weight is big, form removal is difficult.During using wooden model, there is substantial amounts of split bolt hole to need to repair Mend, have an impact to the box beam concrete appearance after shaping, appearance is more and more beautiful during present Bridge Design, linear more and more multiple It is miscellaneous, while when concrete structure external form is irregular, formwork erection is difficult, can not ensure box beam concrete structure external form reach design will Ask, and it is unfavorable to environmental protection using wooden model, while substantial amounts of timber need to be wasted.

Utility model content

Technical problem to be solved in the utility model is：During box beam concrete formwork erection, without to drawing screw, not wasting wood Material, environmental protection, formwork erection and form removal are convenient, the presentation quality of concrete and linear reach design requirement.At the same time solve formwork erection and Form removal is convenient, and cost is low.

Technical solution is used by the utility model solves above-mentioned technical problem：The bed die of box beam is using bamboo splint wood Mould, using Two bors d's oeuveres Φ 48*3.5mm steel pipes as main stupefied wood, is adopted using the lumps of wood of 50*100mm as time stupefied wood below bamboo splint Main stupefied wood is held with the jacking of bowl buckle stent.Box beam flange plate bed die and web external mold use combined type Overall Steel Formwork.In group An angle steel is spliced in the bottom of box-like Overall Steel Formwork, and the lumps of wood of 50*100mm is shelved on angle steel below bottom die of box-beam bamboo splint On, prevent bottom die of box-beam bamboo splint sink so that prevent box beam concrete pour after box beam lower concrete produce grind one's teeth.

Compared with prior art, the utility model has the advantage of：Box beam bottom uses wooden model, can be with composite assembly, weight Amount is light, can facilitate formwork erection and form removal, whole Zhang Mumo plate suqares are big, and seam is few, and concrete is specious.Box beam flange plate bed die Combined type Overall Steel Formwork is used with web external mold, box girder web bottom circular arc chamfering is solved and uses being stranded during wooden model formwork erection Difficulty, ensures the linear beauty after concreting.Timber is not required, it is not necessary to, need to be few with template number to drawing screw, can be multiple It is used in turn, saves artificial.

Embodiment

The bed die of box beam uses bamboo splint wooden model, uses the lumps of wood of 50*100mm to be used as time stupefied wood below bamboo splint Two bors d's oeuveres Φ 48*3.5mm steel pipes hold main stupefied wood as main stupefied wood using the jacking of bowl buckle stent.Box beam flange plate bed die and abdomen Plate external mold uses combined type Overall Steel Formwork.Splice an angle steel, bottom die of box-beam bamboo folder in the bottom of combined type Overall Steel Formwork The lumps of wood of 50*100mm is shelved on angle steel below plate, prevents bottom die of box-beam bamboo splint from sinking, so as to prevent box beam concrete from pouring Box beam lower concrete is produced and ground one's teeth after building.

The utility model is described in further detail below in conjunction with drawing.

Fig. 1 is the steel and wood composite template front elevation of the utility model.The bed die of box beam uses bamboo splint wooden model (A), bamboo folder It is overall using combined type as time stupefied wood, box beam flange plate bed die and web external mold using the lumps of wood (B) of 50*100mm below plate Steel form.The lumps of wood of 50*100mm below a piece angle steel of the bottom of combined type Overall Steel Formwork splicing, bottom die of box-beam bamboo splint Be shelved on angle steel, prevent bottom die of box-beam bamboo splint sink so that prevent box beam concrete pour after box beam bottom coagulation Local products life is ground one's teeth.Below box beam bottom plate, the round steel of diameter 24mm is worn between the combined steel formwork Screw arbor with nut at both-ends supporting rack of left and right Screw arbor with nut at both-ends.Combined steel formwork has panel and following reinforcing rib to be welded, and is shape steel support below reinforcing rib.

Fig. 2 is the auspicious figure of steel and wood composite every template node of the utility model.Splice one in the bottom of combined type Overall Steel Formwork The equal leg angle (C) of root 110*10, is spliced between steel form and equal leg angle using bolt, and bolt uses the circle of diameter 12mm Steel, spacing about 300mm.The lumps of wood of bottom die of box-beam bamboo splint (A) 50*100mm below is shelved on angle steel, prevents bottom die of box-beam bamboo Clamping plate sink so that prevent box beam concrete pour after box beam lower concrete produce grind one's teeth.Below box beam bottom plate, The round steel Screw arbor with nut at both-ends of diameter 24mm is worn between left and right combined steel formwork Screw arbor with nut at both-ends supporting rack (D), when preventing casting concrete Combined steel formwork is moved.

Fig. 3 is the steel form front detail view of the utility model.Panel (E) uses 5mm plates；Reinforcing rib uses 8# channel steels；Branch Support (G) uses 12# channel steels；Flange (F) uses 12*80 band steels, and to be assembled convenient, flange is equipped with positioning pin, and steel are A3 steel.

Fig. 4 is the steel form detail side elevation of the utility model.Monolithic combined steel template length is 2400mm, steel form The equal leg angle (H) of 110*10mm is spliced in bottom, and the spacing between Screw arbor with nut at both-ends supporting rack be 900mm, on side two to drawing spiral shell Bar supporting rack is 300mm with a distance from form stop.

Fig. 5 is pavement figure on the outside of the steel form of the utility model.Pavement panel uses the checkered steel plate of 3mm thickness, It can be replaced with plank, 40mm equal leg angle ribs are welded below the checkered steel plate of 3mm thickness, are 8# channel steels below 40mm equal leg angle ribs Stent, in the steel pipe of one end of 8# channel steel stents welding Φ 48*3.5mm, this steel pipe is welded before combined steel formwork dispatches from the factory, arrives Construction team connects three vertical Φ 48*3.5mm horizontal steel tubes on the steel pipe of Φ 48*3.5mm with fastener behind construction site, this The guard rail when steel pipe of a little Φ 48*3.5mm is as construction, prevents construction personnel from being fallen down in operation from steel form top Come.Between pavement platform and combined steel formwork by the Screw arbor with nut at both-ends supporting rack of the support plate (I) of 5mm and combined steel formwork it Between be bolted, bolt uses diameter 12mm round steel.Splice two people's rows on the combined steel formwork of a block length 2400mm Road supporting rack.

Fig. 6 is that the steel and wood composite template support bracket of the utility model sets up instance graph.The bed die of box beam uses bamboo splint Wooden model, it is stupefied as master using Two bors d's oeuveres Φ 48*3.5mm steel pipes using the lumps of wood of 50*100mm as time stupefied wood below bamboo splint Wood, main stupefied wood is held using the jacking of bowl buckle stent.Box beam flange plate bed die and web external mold use combined type Overall Steel Formwork. The lumps of wood of 50*100mm is shelved on angle below a piece angle steel of the bottom of combined type Overall Steel Formwork splicing, bottom die of box-beam bamboo splint On steel, prevent bottom die of box-beam bamboo splint from sinking, thus prevent box beam concrete pour after box beam lower concrete produce it is wrong Tooth.The bottom of combined type Overall Steel Formwork is laid on the cross bar on bowl buckle holder jacking along bridge to the lumps of wood, the lumps of wood is laid with.Bowl buckle Stent erection method and requirement and basement process are carried out according to custom requirements.
