The invention discloses a novel steel truss concrete slab form support system which comprises steel truss shaped steel beams (3), an I-shaped steel keel (5), a forming template box (1), a square wooden column (2), steel plate welding corbel-pieces (6) and a to-be-poured concrete floor (4), wherein the I-shaped steel keel (5) is arranged between the steel truss shaped steel beams (3) and serves as a template supporting main keel; the square wooden column (2) is distributed in vertical to the I-shaped steel keel (5), and the forming template box (1) is arranged at the upper part of the square wooden column (2); the forming template box (1) serves as a concrete slab bottom form; and the steel plate welding corbel-pieces (6) are welded on the steel truss shaped steel beams (3). The novel steel truss concrete slab form support system provided by the invention has the advantages that the support system is simple to operate, the investment is reduced, and influence, which is caused by reinforcing a lower part floor, on others procedures of construction in the lower part floor can be avoided.
Description
Technical field
The present invention relates to a kind of novel slab form support system; Particularly relate to a kind of new steel truss concrete floor form bracing system, the invention still further relates to this system purposes as support system in other steel structure girder ordinary reinforced concrete slab forms of steel truss concrete slab form neutralization.
Background technology
In the concrete floor form bracing system of routine, generally be on the floor of bottom, to set up full hall scaffold as the support system that supports the top beam-slab template.But when steel truss below height was big, the common steel tube scaffold system can't satisfy force request, needed to adopt mode such as lattice column to reinforce, and cost is higher; Also need reinforce simultaneously, not only produce a large amount of expenses, and influence the carrying out of operations such as the decorations in the floor of bottom, dynamo-electric installation, thereby influence the construction period of whole engineering the substructure floor.
For addressing the above problem; The invention provides a kind of new steel truss concrete floor form bracing system; No longer adopt the full hall scaffold, lattice column of traditional construction technology support system, but directly adopt the steel truss set up in steel work or the i iron keel on the girder steel support system as floorslab concrete as concrete floor.
Summary of the invention
The invention discloses a kind of new steel truss concrete floor form bracing system; Comprise steel truss section steel beam, i iron keel, forming panel box, square wooden a tree, used in making timber for boats, steel plate welding bracket, concrete floor to be built, wherein: said i iron keel are arranged between the steel truss girder steel; The vertical i iron keel of said square wooden a tree, used in making timber for boats distribute and the forming panel box are set at an upper portion thereof; Said forming panel box is as the concrete floor bed die; Said steel plate welding bracket is welded on the steel truss section steel beam.
Said steel truss section steel beam is the for example steel work spandrel girder of I shape, box-shaped, grooved of H section steel beam or other section forms.
Said i iron keel are generally No. 16 or higher model i iron, and as the main load-carrying member of support shuttering, the concrete use model of i iron can be according to choosing after the Force Calculation; I iron keel one end can be placed on to connect and is put on the steel plate welding bracket, also can be placed on the edge of a wing of steel truss i iron to reduce steel plate welding bracket welding capacity, and i iron size and arrangement pitches calculate according to slab thickness to be confirmed.
Said forming panel box adopts common templates and wooden a tree, used in making timber for boats to process in advance, and the lattice size that planar dimension press truss is provided with, and box height is according to the girder steel size, and design such as bracket position is definite, and its end face absolute altitude is an absolute altitude at the bottom of the concrete floor.Adopt wooden a tree, used in making timber for boats or other materials to support in the box, guarantee to have enough intensity to bear concrete load and working load.
Said square wooden a tree, used in making timber for boats cross section can be preferably square for rectangle or square, the square sectional of 100mm * 100mm for example, and cross-sectional sizes and spacing etc. can be calculated according to wooden a tree, used in making timber for boats stress performance and slab thickness and confirm.
Said steel plate welding bracket for example uses the Q235 steel plate, and thickness is greater than or equal to the web thickness of i iron keel, plays the effect of supporting the i iron keel, and size is confirmed according to Force Calculation.Bracket face absolute altitude is definite according to the less girder steel in cross section, template box height etc., can be according to H=H
1-H
2-H
3-H
4-H
5(wherein H is a bracket face absolute altitude, H in calculating
1Be concrete floor face absolute altitude, H
2Be concrete building plate thickness, H
3Be forming panel box height, H
4Be wooden a tree, used in making timber for boats thickness, H
5Be i iron keel height).Bracket need have the load that enough bearing capacities are born the i iron keel.
Form bracing system of the present invention can be removed through the handling frame of finishing usefulness when furred ceiling is fitted up.
Beneficial effect of the present invention is: new steel truss concrete floor form bracing system of the present invention; Utilize the structural iron truss self to bear this layer concrete dead load and working load; Avoided supporting concrete floor, thereby practiced thrift a large amount of working measure expenses, simultaneously with setting up full hall frame; Avoided floor other construction technologies in bottom being exerted an influence, helped shortening the construction period because of setting up full hall frame.Support system operation of the present invention is simple and easy, has reduced the input of manpower and materials.

The specific embodiment
Below in conjunction with accompanying drawing 1-2 the present invention is described exemplarily, but the said specific embodiment is not construed as limiting the invention.
New steel truss concrete floor form bracing system as shown in the figure; Comprise steel truss section steel beam 3, i iron keel 5, forming panel box 1, square wooden a tree, used in making timber for boats 2, steel plate welding bracket 6, wait to build concrete floor 4; Said i iron keel 5 are arranged between the steel truss girder steel 3 and as the main load-carrying member of support shuttering; Said square wooden a tree, used in making timber for boats 2 vertical i iron keel 5 distribute and forming panel box 1 are set at an upper portion thereof; It is the bed die of concrete floor 4 that said forming panel box does 1, and said steel plate welding bracket 6 is welded on the steel truss section steel beam 3, as the support of i iron.
The specific embodiment is following:
Steel plate is welded bracket be welded on the mounted steel truss section steel beam, on mounted girder steel and steel plate welding bracket, set up the i iron keel then; I iron keel one end can directly be put on the edge of a wing of steel truss i iron to reduce bracket welding job amount; After the i iron keel are set up completion, wooden a tree, used in making timber for boats is set up on the i iron keel according to the design-calculated spacing; Make the forming panel box, it is erected on the square wooden a tree, used in making timber for boats.The colligation floor bar waters build floor.Also can the bracket position be raised, change the forming panel box into common templates, guarantee that common templates end face absolute altitude is an absolute altitude at the bottom of the concrete floor.
