Abstract
The utility model relates to a steel keel for wall, beam and pillar formworks, and belongs to the field of formwork construction of building construction. The steel keel comprises channel steel, supporting hooks and nail holes, wherein a channel of the channel steel is provided with a plurality of nail holes and welded with a plurality of supporting hooks to form the steel keel for the wall, beam and pillar formworks. The steel keel has the advantages that a worker uses a large steel nail which is 70mm long when a wooden keel is used and uses a small steel nail which is 15mm long when the steel keel is used, so that the usage of the steel nail is reduced by 78%; the steel keel is provided with the supporting hooks on which normal steel pipes for fixation can be placed, so that a worker can complete operation separately; the steel keel is customized in various sizes so as to be assembled simply by the worker without special knowledge; and furthermore, the steel keel can be used for over 500 times so as to reduce the construction cost and bring good economic benefits to the enterprises.
Description
Technical field
The utility model relates to a kind of wall, beam, post formwork steel joist, belongs to the template construction field of building operations.
Background technology
At present, the keel that use in China template construction field mainly are rough grounds, and a large amount of uses of rough ground must cause a large amount of felling of trees, cause serious destruction to natural environment, so nation-building department has encouraged energetically research and development and used the construction material that can replace rough ground.Because in use there is following defective in the characteristic of rough ground self: 1, owing to a little less than the compressive strength, must adopting the mode of vertical usefulness could increase compressive strength, rough ground is connected connection with regard to steel nail that need to be larger with template like this; 2, rough ground self does not have attachment device, necessary many people coordinating operation when the workman operates; 3, the great advantage of rough ground is the demand according to engineering, how long how long saw, and this advantage has reduced the use number of turnover of rough ground just, causes serious economic loss to construction enterprises.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of wall, beam, post formwork steel joist, can solve the larger steel nail of the use described in the background technology, the problem that many people coordinating operation and the number of turnover reduce during operation.
The utility model is carried out by following technical scheme, a kind of wall, beam, post formwork steel joist, and it comprises channel-section steel, hook, nail hole three parts.Be equipped with some nails hole in the groove of described channel-section steel, and be welded with some hooks and form a kind of wall, beam, post formwork steel joist.
Described nail hole is connected with template by the nail hole with steel nail for be equipped with some nails hole in the groove of channel-section steel.
Described hook is for being welded with some hooks in the groove of channel-section steel, hook is used for propping up common steel tube.Hook has three kinds, is respectively steel plate hook, the U-shaped hook of round steel, round steel L-type hook.
The utility model has the advantages that: when using rough ground, what the workman adopted is the long large steel nail of 70mm, uses the steel joist workman to adopt the long little steel nail of 15mm just passable, on steel nail uses one with regard to cost 78%; Steel joist carries hook, reinforces can prop up on hook with common steel tube, and a workman just can operate separately; Steel joist is many specifications scale keel, and the workman need not professional knowledge, as long as simple assembling is just passable; Steel joist can have enough to meet the need and use more than 500 time, has reduced construction cost, has brought good economic benefit to enterprise.
