Abstract
In order to solve the problem that an existing crowbar is inconvenient to use in the process of dismantling a constructional engineering formwork, the utility model provides a telescopic crowbar used for dismantling the constructional engineering formwork. The telescopic crowbar comprises a crowbar head piece, a handle, a first extension rod and a second extension rod, wherein one end of the first extension rod is connected with the crowbar head piece, the other end of the first extension rod is movably arranged on the inner side of the second extension rod, the second extension rod is movably arranged on the inner side of the handle, and the position between the handle and the second extension rod and the position between the second extension rod and the first extension rod are adjusted and fixed through limiting bolts. The telescopic crowbar has the advantages of being simple in structure, convenient and fast to manufacture, low in cost, and convenient to use and carry, and can be circulated and used in different projects.
Description
Technical field
The utility model belongs to the realm of building construction, is specifically related to the telescopic crowbar for the building engineering shuttering Demolition Construction.
Background technology
Along with improving constantly of construction technology, builing industry just transforms to technology-intensive type from labor-intensive, by a large amount of employings of advanced technology and process equipment, with satisfy present stage to construction work to labour demand.Yet engaging in the increasing rapidly of in short supply and work unit price of the quantity of labour force of builing industry, in the urgent need to alleviating above-mentioned pressure by the mode that improves effect, is to improve equipment to improve effect and improve the effect approach.
In the past structure construction complete after, what workman's form removal used is the reinforcement fabrication crowbar, but because story height is different, a size crowbar can not satisfy the form removal job requirement when form removal, in order to make things convenient for form removal construction workman generally to adopt dual mode, the one, be with several specification crowbars to construct; The 2nd, the dismounting of ascending a height of band cat ladder.Front a kind of mode need to be carried the in the venue back and forth transhipment of crowbar of different specification size, is inconvenient to construct, and affects effect; There is the problem that construction is inconvenient, effect reduces that causes because transporting back and forth step ladder equally in rear a kind of mode, and in addition, also there is certain potential safety hazard in workman's ascend operation.
In sum, be badly in need of at present a kind of crowbar that can regulate length, to solve the form removable difficulty that causes because of the building structure height relief, the technical barrier that operating efficiency is low.
Adopt in a word above the sort of mode effect that decrease is all arranged, therefore adopt and a kind ofly can carry out according to the crowbar of the highly different extension types of building structure the form removable construction, because easy to carry, and step ladder not, greatly improve the construction effect.Be particularly suitable for the sort of form removable work that the building of different structure height change is arranged with layer, adopt this extension type crowbar splendid to improving the effect effect.
The utility model content
In order to solve the above-mentioned technical barrier in construction work form removal process, the form removal instrument of different size is provided when providing a kind of appropriate architecture engineering different templates to remove the utility model.
Concrete technical solution is as follows:
The telescopic crowbar that is used for the building engineering shuttering Demolition Construction, comprise pry head part 1 and handle 2, wherein an end of pry head part 1 is provided with the silk mouth, the other end of pry head part 1 is provided with bifurcated or perk member, in addition, described telescopic crowbar for the building engineering shuttering Demolition Construction also comprises the first extension rod 31 and the second extension rod 32; Wherein, handle 2, the first extension rod 31 and the second extension rod 32 are the cylindrical tube of hollow; One end of the first extension rod 31 is connected with pry head part 1, and the other end of the first extension rod 31 is located at the inboard of the second extension rod 32 movably, and the second extension rod 32 is located at the inboard of handle 2 movably; Handle 2 and the second extension rod 32 are respectively equipped with a through hole on the barrel of pry head part 1 one ends, in through hole, all is furnished with a caging bolt 4, by the position relationship between caging bolt 4 adjustings and fixed handle 2 and the second extension rod 32, the second extension rod 32 and the first extension rod 31.
Useful technique effect of the present utility model is:
Because this product can be adjusted the different length size according to needs, reduce and carry transhipment in the different size crowbar place, convenient construction, when using this product simultaneously, do not need ascend operation, reduce the up and down time of cat ladder, transhipment cat ladder, improve the form removable operating efficiency, and avoid the potential safety hazard of ascending a height.At last, what this product can be repeatedly is recycling, and makes simply, quick, and cost is low, and construction efficiency is high, saves artificial and duration.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Referring to Fig. 1, the telescopic crowbar that is used for the building engineering shuttering Demolition Construction, comprise pry head part 1 and handle 2, wherein an end of pry head part 1 is provided with the silk mouth, the other end of pry head part 1 is provided with bifurcated or perk member, see Fig. 2 for details, in addition, described telescopic crowbar for the building engineering shuttering Demolition Construction also comprises the first extension rod 31 and the second extension rod 32; Wherein, handle 2, the first extension rod 31 and the second extension rod 32 are the cylindrical tube of hollow, referring to Fig. 2 and Fig. 3; One end of the first extension rod 31 is connected with pry head part 1, and the other end of the first extension rod 31 is located at the inboard of the second extension rod 32 movably, and the second extension rod 32 is located at the inboard of handle 2 movably, referring to Fig. 3; Referring to Fig. 4, handle 2 and the second extension rod 32 are respectively equipped with a through hole on the barrel of pry head part 1 one ends, in through hole, all is furnished with a caging bolt 4, position relationship by between caging bolt 4 adjustings and fixed handle 2 and the second extension rod 32, the second extension rod 32 and the first extension rod 31 sees Fig. 5 for details.
In addition, pry head part 1 is bent by the reinforcing bar of long 100mm to 150mm, diameter 20mm to 50mm and forms.
In addition, the length of handle 2, the first extension rod 31 and the second extension rod 32 is between 0.5m to 2m.
Referring to Fig. 6, this product is in time spent not, and collapsible length is convenient to transhipment and is stored.
During use, the operator at first unscrews caging bolt 4, the story height of stripping is adjusted the length of this product as required, namely adjusts length between handle 2 and the second extension rod 32 and the length between the second extension rod 32 and the first extension rod 31, screws subsequently caging bolt 4 again.Afterwards, the constructor holds handle 2, by pry head part 1 is top-down template is removed one by one.This product does not use the different crowbars of length owing to not needing to change, and does not need up and down ascend operation, has improved effect, the saving duration; In addition, this product is that common galvanized pipe is made, and the cost input is low, making is simple, easy to carry, can forward different engineerings week to and use, and has saved material.
