Description

Formwork system of thin-wall steel formwork

Technical Field

The utility model relates to a concrete form field of strutting specifically is a formwork system of thin wall steel form.

Background

In the traditional formwork process, steel pipes and square timbers are usually adopted as main and secondary back ridges of the formwork, and steel pipes and cross fasteners are mostly adopted for reinforcement. The template system has the characteristics of simple support, easy disassembly and assembly, saw cutting, capability of meeting the requirements of various building sizes and strong applicability. However, the rigidity of the formwork system is poor, the construction randomness of operators is high, and the phenomena of 'formwork running' and 'formwork expansion' often occur in the concrete pouring process, so that the construction quality is difficult to guarantee.

Specifically, the steel pipe square timber formwork support system has the following disadvantages:

A. because the mechanical properties difference of square timber and steel pipe is very big, often appear because of the square timber when compressed, produce the phenomenon that warp and lead to the slip form in the contact department with the steel pipe, construction quality is difficult to guarantee, still need the later stage by workman's repair, not only extravagant manual work, still influence the time limit for a project progress.

B. Due to the fact that the wet expansion and dry shrinkage of the square timber are large, when the square timber is poured and pounded, if the square timber is not properly treated, warping and cracking are prone to occur, phenomena of mold expansion, section size bulging, slurry leakage and the like can occur, and the poured concrete cannot be molded according to the pre-designed design easily.

C. The worker can cut and saw the square timber randomly and wastes the square timber, and the cut timber and the cut steel pipe can not be recycled, so that great difficulty is brought to the control of the construction cost.

D. A large amount of wood is used, the traditional formwork supporting process is statistically adopted, 1 cubic meter of wood is needed for every 100 square meters of building area, and 20% -30% of wood loss is caused after construction is finished, so that forest resources are damaged. And a large amount of wood is stored in a construction site, so that a fire disaster is more easily caused.

E. The randomly built supporting system causes messy site and inconvenient traffic.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned defect, provide a modularization and difficult displacement and repeatedly usable's formwork system.

In order to achieve the above object, the present invention is realized as follows:

a formwork system of a thin-wall steel formwork comprises a main back ridge, an inner eave adjustable secondary back ridge, an outer eave fixed-length secondary back ridge, a hole lockset, an external corner lockset, a wall bushing, a vertical wall ejector rod and a connecting lockset; the main back edge, the adjustable secondary back edge of the inner eave and the fixed-size secondary back edge of the outer eave are all of telescopic sleeve pipe structures with rectangular sections; after the inner wall formwork is erected, a wall bushing is arranged on the inner wall formwork and a wall bolt is arranged in a penetrating manner; the secondary adjustable back edge of the inner eave and the secondary fixed-length back edge of the outer eave are uniformly placed on two sides of the template; the main back edge is hung on a through-wall bolt, the main back edge is assembled in any length by using a connecting lock according to the requirement of the size of a wall body, an external corner lock and a hole lock are installed on a hole and an internal corner and an external corner, and a vertical wall ejector rod is used for supporting and pulling the outer side of the wall body, so that the perpendicularity of the wall body is ensured.

The formwork system of thin wall steel form, external corner tool to lock and entrance to a cave tool to lock all include the sleeve pipe and wear to establish screw rod and nut on the sleeve pipe, overlap the sleeve pipe box in the juncture of each back of the body stupefied, the stupefied top of each back of the body is tight through the screw rod that penetrates, the nut is located the sleeve pipe, locks the screw rod from the reverse to realize the purpose that the tool to lock fastens.

The utility model adopts the above design, stupefied to strut the template of the back of the body for the rectangle through the cross-section to the stupefied handing-over department of main, inferior back of the body becomes "face" contact by original "point" contact, and area of contact is big, and the atress is even. The main back ridge and the secondary back ridge are made of the same material and have consistent deformation. Thereby improving the strength and rigidity of the template.
