It is preferred that, in above-mentioned beam and slab type raft foundation formwork support structure, framework of steel reinforcement is provided with oblique for fixing reinforcing bar The stirrup of support, reinforcing bar diagonal brace upper end is connected with the stirrup, and reinforcing bar diagonal brace bottom is located at pad through what the raft foundation was constructed Bottom plate above layer is fixedly connected to bed course and with the baseplate reinforcing bar of bottom plate, and/or reinforcing bar diagonal brace bottom is with being inserted vertically into bed course Reinforcing bar be fixedly connected.
It is preferred that, in above-mentioned beam and slab type raft foundation formwork support structure, the stirrup for fixing reinforcing bar diagonal brace is Interval 900mm's sets up stirrup, and the laterally disposed reinforcing bar diagonal brace is used as with a diameter 14mm of setting reinforcement welding.
It is preferred that, in above-mentioned beam and slab type raft foundation formwork support structure, the reinforcing bar diagonal brace is located to be installed with beam steel The relative side in side template side.
It is preferred that, in above-mentioned beam and slab type raft foundation formwork support structure, in the framework of steel reinforcement of construction foundation beam, relatively Two reinforcing bar diagonal braces in " X " type it is arranged in a crossed manner.
After adopting the above technical scheme, the utility model has the advantages that compared with prior art:
1st, the utility model is cancelled due to the horizontal cross support system between beam in length and breadth, and shuttering supporting workload drops significantly It is low, so as to greatly save engineering cost;
2nd, beam and slab type raft foundation template of the present utility model uses lateral support structure, is that the work that pours of concrete is carried The working face of abundance has been supplied, guarantee has been provided for the pouring quality of concrete, has not only saved engineering material, and decrease The input of labour, accelerates engineering construction speed, reduces input cost;
The utility model causes work progress to avoid the rambling phenomenon of working face that traditional support method is caused, existing Field safety construction level obtains very big change, with higher promotional value.

Fig. 2 is a kind of schematic diagram of beam and slab type raft foundation formwork support structure of the utility model;
In figure:
1- bottom plates;2- stirrups;3- frameworks of steel reinforcement;4- reinforcing bar diagonal braces;5- bed courses;6- baseplate reinforcing bars;7- templates;8- is to drawing spiral shell Bolt;9- inserts the reinforcing bar of bed course;10- beam steels.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is described in further detail, to help understanding that this practicality is new The content of type.
As shown in Fig. 2 installed in a kind of beam and slab type raft foundation supporting construction, including framework of steel reinforcement 3, framework of steel reinforcement 3 The split bolt 8 of side template 7 and fixed side template 7, these components are constituted with inserting the reinforcing bar 9 of bed course 5 in interval vertical Raft foundation formwork bracing system, framework of steel reinforcement 3 is formed to construct foundation beam by beam steel 10 and stirrup colligation;Framework of steel reinforcement 3 On set up the stirrup 2 of fixed reinforcing bar diagonal brace 4, the upper end of reinforcing bar diagonal brace 4 is fixedly connected with the stirrup 2, reinforcing bar diagonal brace bottom with it is described The reinforcing bar 9 of insertion bed course is fixedly connected with the reinforcing bar diagonal brace 4 as the lateral tilt of beam steel 10;Raft foundation, which is constructed out, to be located at Baseplate reinforcing bar 6 is provided with the bottom plate 1 of the top of bed course 5, bottom plate 1, the bottom of reinforcing bar diagonal brace 4 can also pass through bottom plate 1 to bed course 5 and bottom Slab muscle 6 and/or the electric welding fixation of reinforcing bar 9 for inserting bed course, reinforcing bar 9 is the bar dowel for being inserted vertically into bed course;It is preferred that, for solid Determine spacing 900mm between the stirrup 2 of stirrup diagonal brace 4, the reinforcing bar of a diameter 14mm is set as the lateral branch of the framework of steel reinforcement 3 In support, the framework of steel reinforcement 3 for constructing foundation beam, relatively-stationary reinforcing bar diagonal brace 4 can be arranged in a crossed manner.
When it is implemented, being determined according to obtained control point coordinates, absolute altitude and general arrangement plan, construction drawing etc. Position, and according to drawing and code requirement, beam steel 10 and the colligation of stirrup 2 are constituted into framework of steel reinforcement 3, while increase is reserved in other words Go out the stirrup 2 to fixed reinforcing bar diagonal brace 4.The colligation of framework of steel reinforcement 3 of construction foundation beam is finished, and is increased according to the interval of stirrup 2 900mm Plus one diameter 14mm reinforcing bar as the lateral reinforcement diagonal brace 4 of the framework of steel reinforcement 3, the upper end of reinforcing bar diagonal brace 4 is fixedly connected on stirrup 2 On, the bottom of reinforcing bar diagonal brace 4 is through bottom plate 1 to bed course 5 and is welded and fixes with baseplate reinforcing bar 6, and/or sets on bed course 5 short steel Muscle, the reinforcing bar 9 of the insertion bed course is welded and fixed as the strong point of the bottom of reinforcing bar diagonal brace 4.
Reinforcing bar diagonal brace 4 is set up, after instrument levelling, hangs Side shuttering horizontal line to determine the absolute altitude and level at template bottom Direction position;Determine it is errorless after, welding template level branch drag, the template 7 prepared is installed to construct foundation beam, mould in place Plate 7 is reinforced by split bolt 8, is fixed the template 7 installed and the colligation of framework of steel reinforcement 3 with galvanized wire.Wherein, it is described Reinforcing bar diagonal brace 4 is located at the side relative with this side of the supporting module 7 of beam steel 10;After the colligation of framework of steel reinforcement 3, construction foundation beam Two outside supporting modules 7 of framework of steel reinforcement 3, reinforcing bar diagonal brace 4 is located in the framework of steel reinforcement 3, the two relative steel in framework of steel reinforcement 3 Muscle diagonal brace 4 can be arranged in a crossed manner in " X " type, realize beam steel level to vertically to reinforcing, without level between foundation beam Horizontal support, reduces working face and takes, facilitate concrete pouring construction.
The utility model is cancelled due to the horizontal cross support system between beam in length and breadth, and shuttering supporting workload drops significantly It is low, so as to greatly save engineering cost;Beam and slab type raft foundation template of the present utility model uses lateral support knot Structure, for the working face that work provides abundance that pours of concrete, provides guarantee for the pouring quality of concrete, not only saves Engineering material, and decrease the input of labour, engineering construction speed is accelerated, input cost is reduced;This practicality is new Type causes work progress to avoid the rambling phenomenon of working face that traditional support method is caused, site safety civilized construction water It is flat to obtain very big change, with higher promotional value.
