Abstract
The utility model discloses double C-shaped building formwork support keels filled with wood-like pulp. The double C-shaped building formwork support keels comprise double symmetrical C-shaped metal channels (1), a reinforcing plate (3) connected between the double C-shaped metal channels (1) and the wood-like pulp (2) filled in the metal channels, wherein the reinforcing plate (3) is provided with a through hole (4). The double C-shaped building formwork support keels have the advantages of no distortion, no horizontal slip during material filling, easiness in processing and manufacturing and low cost.
Description
Technical field
The utility model relates to metal ribs concrete structure formwork support technology field, relates in particular to the structure of construction formwork support keel.
Background technology
In construction work, reinforced concrete structure forming quality key is the template installation quality, and the key of template installation quality is formwork bracing system.Guarantee formwork bracing system intensity, rigidity and stability, the support vertical rod in the support system, keel, connector play conclusive effect.The Load Transfer that support keel transmits template is to supporting vertical rod, and its intensity, rigidity and stability directly influence the performance of template installation quality and function.
Current in engineering practice the keel of formwork bracing system shaped steel keel, rough ground, aluminium alloy joist etc. are arranged, but all have certain defective.Exist weight big as the shaped steel keel, will use a large amount of plant equipment in the construction, labor cost is big etc.; Rough ground exists rigidity little, and damaged easily, the number of turnover is low, is unfavorable for economizing on resources; There is disposable input cost height in aluminium alloy joist.
Existing metal bag wood building formwork support keel structure is by wooden a tree, used in making timber for boats outer wrapping metal sheet and carry out the antirust, anti-corrosive processing, forms compound keel structure, and it is big both to have overcome shaped steel keel weight, the defective of constructing operation inconvenience; Also overcome little, the easy breakage of normal wood keel rigidity, the number of turnover is low, thereby causes the cost height, be unfavorable for the defective that economizes on resources; Also solved the high problem of the disposable input cost of aluminium alloy joist simultaneously.But the defective that this utility model exists is: A, wooden a tree, used in making timber for boats need carry out anticorrosion setting to be handled, and when particularly the setting processing was not in place, metal bag wood building formwork support keel just might produce torsional deformation and influence use; B, in actual applications, when the support keel carrying be beam working load or floor slab construction load the time, usually C type metallic channel aperture position up so that the nail of construction formwork and support keel is consolidated.Owing to be filled between interior wooden a tree, used in making timber for boats of C type metallic channel and the C type metallic channel and lack necessary deformation constrain power, thereby make under the vertical gravity load effect of beam or floor, effect owing to longitudinal shear power between wood a tree, used in making timber for boats and the C type metallic channel base plate will produce horizontal sliding, causes wooden a tree, used in making timber for boats and C type metallic channel non-integral producing balanced forces and is easy to generate non-homogeneous stressed breakage;
C,Closely cooperate between wood a tree, used in making timber for boats and the C type metallic channel and increased difficulty and cost to processing and fabricating.
Summary of the invention
The purpose of this utility model provides a kind of torsional deformation, inserts of can not producing can not produce the construction formwork support keel that horizontal sliding, processing and fabricating is easy, cost is low double C-type are filled imitative wood pulp material just in order to overcome the weak point that above-mentioned prior art exists.
The purpose of this utility model is achieved by the following technical solution:
A kind of double C-type is filled the construction formwork support keel of imitative wood pulp material, and the double C-type metallic channel of the utility model employing symmetry and the gusset that is connected between the double C-type metallic channel constitute with the imitative wood pulp material that is filled in the metallic channel, offer through hole on gusset.
The utility model utilization is connected the through hole of offering on the gusset of two C metallic channels, thereby make the imitative wood pulp material filler that is filled in the double C-type metallic channel run through formation integral body up and down, the non-position of running through of two C connecting portions then becomes imitative wood pulp material filler metal inner frame, produce bigger deformation constrain power between filler and the metallic channel, form whole producing balanced forces system and be not easy to produce non-homogeneous stressed breakage; Double C-type metallic channel inner stuffing is solidified by liquid slurry and forms, and this causes support keel to produce closely cooperating between the problem of torsional deformation and wooden a tree, used in making timber for boats and the C type metallic channel processing and manufacturing difficulty that causes greatly and the high problem of cost with regard to having overcome the setting of wooden a tree, used in making timber for boats and dealing with improperly.
The construction formwork support keel of the imitative wood pulp material of a kind of double C-type filling described in the utility model bends stamping forming double C-type metallic channel by sheet metal and constitutes with the imitative wood pulp material that is filled in the metallic channel.Require: the intensity that the length size of described double C-type metallic channel and plate thickness are considered according to wall beam support system needs, rigidity and stability determine that by calculating its surfaces externally and internally carries out antirust processing; Two C connecting portions of described double C-type metallic channel are arranged with through hole.
Concrete make processing can be in accordance with the following methods:
At first make the double C-type metallic channel: length and the plate thickness of determining the double C-type metallic channel according to intensity, rigidity and the Calculation on stability of the consideration of wall beam support system needs, select cold the repulsing or subdue the enemy of material to be pressed into the C type metallic channel of band with through hole, two C type metallic channel superimposed back-to-back employing pressure touch welding manners or anchor connection mode are formed the double C-type metallic channel, and carry out the antirust processing of surfaces externally and internally.
The imitative wood pulp material of perfusion: the imitative wood pulp material of perfusion in the double C-type metallic channel, maintenance solidify to form construction formwork support keel product.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cross-section structure signal of Fig. 1.
The specific embodiment
As Fig. 1, shown in Figure 2, a kind of double C-type is filled the construction formwork support keel of imitative wood pulp material, and the double C-type metallic channel 1 of the utility model employing symmetry and the gusset 3 that is connected between the double C-type metallic channel 1 constitute with the imitative wood pulp material 2 that is filled in the metallic channel, offer through hole 4 on gusset 3.This through hole 4 can be arranged formation more than one.
Intensity, rigidity and the Calculation on stability that the utility model is considered according to wall beam support system needs determined the length and the plate thickness of double C-type metallic channel, select cold the repulsing or subdue the enemy of material to be pressed into the C type metallic channel of band with through hole, two C type metallic channel superimposed back-to-back employing pressure touch welding manners or anchor connection mode are formed the double C-type metallic channel, and carry out the antirust processing of surfaces externally and internally; The imitative wood pulp material of perfusion in the double C-type metallic channel, maintenance solidify to form construction formwork support keel product.
