Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model is used for the inner support positioner of building girder template, comprise two for insert beam forms two pieces of side templates 4 between and backstay 1, two backstays 1 offseted with the medial surface of two pieces of side templates 4 be respectively connected with and grasp bar 3 and for offseting with the transverse blocking-rod 2 of limited inserting depth with two pieces of side templates 4.Wherein, two backstays 1 are all vertical with transverse blocking-rod 2, grasp bar 3 parallel with transverse blocking-rod 2, and middle part and the transverse blocking-rod 2 of backstay 1 are affixed, and the two ends grasping bar 3 are fixed in the end of two backstays 1 and insertion end opposite end respectively.The insertion end of each backstay 1 is 100mm to the distance of transverse blocking-rod 2.
In the present embodiment, each backstay 1 is equipped with the first locating surface 11, first locating surface 11 and contacts with side template 4 and coordinate, and can improve contact area, ensures that positioning stablity is reliable.Transverse blocking-rod 2 is provided with the second locating surface 21, second locating surface 21 and coordinates with the upper end plane-plane contact of side template 4, can improve contact area equally, ensures that positioning stablity is reliable.
In the present embodiment, grasp bar 3, transverse blocking-rod 2 and two backstays 1 and be angle steel, three forms inner support positioner by welding.During making, the spacing between priority control two backstays 1, departure scope 0 to+2mm.Material, the wall thickness of angle steel need meet the requirements, and ensure to have enough intensity, rigidity and stability, and what the present embodiment adopted is the angle steel of ∠ 25 × 3.
When inner support positioner the utility model being used for building girder template is applied to construction, between the two pieces of side templates 4 inner support positioner being inserted in beam forms according to 500mm interval vertical, fastening side template 4 outer hoop, check template and wait for concreting.During concreting, concrete enters mould, be full of after can extract inner support positioner, cleaning out, reclaiming in order to using next time.
For the upper and lower string beam of prefabricated roof truss, specifically can comprise the following steps:
(1) preparation of construction
Before construction, make, check whether the specification of inner support positioner meets the requirements.
(2) line setting, loose tool of laying bricks
Assigned address 1:1 ratio is released roof truss and is put down outer edge in sleeping prefabricated chord member beam at the scene, and build brick loose tool by laying bricks or stones with MU10 common brick M7.5 composite mortar, brick loose tool contrasts drawing after building by laying bricks or stones and carries out an acceptance inspection.
(3) reinforcing bar binding
By design pitch chalk setting-out assembling reinforcement on loose tool, after carry out reinforced bar engineering and inspect for acceptance.
(4) web member, reserved, pre-buried installation
According to designing requirement, roof truss web member prefabricated is in advance placed to assigned address.Carry out the pre-buried installation of roof truss reserving hole, bellows, ironware simultaneously.
(5) beam side pre-installation
By lower edge on two of beam forms pieces of side template 4(roof trusses) be placed on relevant position by number, set up steel-tube die support, carry out template pre-installation.
(6) side template 4 setting-out location suitable for reading
Use red symbol pen, lower edge on side template 4(roof truss) suitable for readingly press the setting-out of 500mm spacing, as the installation site line (side template 4 joint location must increase an inner support positioner) of inner support positioner.
(7) inner support positioner is laid
Vertically inserted in two pieces of side templates 4 by inner support positioner in above-mentioned setting-out position, being inserted to transverse blocking-rod 2, to be close to side template 4 suitable for reading; Fastening side template 4 outer hoop completes model sheetinstallat, checks beam section size.
(8) reinforcing bar, reserved, pre-buried, template examination
Before the complete concreting of model sheetinstallat, examination is combined to reinforcing bar, reserved, pre-buried, template, runs concealment acceptance record well.
(9) concreting
Carry out concreting according to code requirement, build, while vibrate, make concrete reach the compactness of regulation.According to the universal method of embedded reinforcement inner support, during concreting, vibration easily causes the displacement of reinforcing bar inner support, makes template out of hand, and beam section size produces error.
(10) inner support positioner reclaims
During concreting, concrete enters mould, is full of is that available reinforcing bar prizes gently, extracts inner support positioner; Tool-type formwork inner support is cleaned out, checks its outward appearance, be recovered to after meeting instructions for use together, be convenient to utilize next time.
For certain work items: the method according to the permanent reinforcing bar inner support of general pre-buried: 30m span prestressed roof truss 144 Pin, every Pin will establish inner support 100; 24m span prestressed roof truss 396 Pin, every Pin will establish inner support 80.Need Φ 14 reinforcing bar inner support 17458.8kg.
And when adopting inner support positioner of the present utility model to construct, 30m span prestressed roof truss 144 Pin, construct 4 Pin at every turn simultaneously, makes 4 covers, often overlaps 100 (spacing between two backstays 1 is each 50 of 320mm and 220mm, often overlaps turnover 36 times); 24 m span prestressed roof truss 396 Pin, construct 4 Pin at every turn simultaneously, makes 4 covers, often overlaps 80 (spacing between two backstays 1 is each 40 of 300mm and 220mm, often overlaps turnover 99 times).Need ∠ 25 × 3 angle steel: 1.2m × (100+80) × 4 covers × 1.12kg/m=967.7kg.
Comparing calculation is known, adopts the construction of inner support positioner can save cost of materials (steel): 17.46t × 3684 yuan/t-0.97t × 3674 yuan/t=60758.8 yuan; Save reinforcement cover: (144 × 105+396 × 135) × 0.04 yuan/only=2743.2 yuan; Save artificial, mechanical expense: (144 × 105+396 × 135) × 0.02 yuan/only=16822.7 yuan installed by steel bar meter 17.46t × 992 yuan/t-angle steel tool-type formwork inner support processing 0.97t × 1927 yuan/t+topping; Save inner support positioner and reclaim residual value: 0.97 × 2000=1720 unit.Quality and benifit: as adopted common practice once there is quality accident, often damage 30,000 yuan, a Pin roof truss.To sum up can add up to saving 112044.7 yuan, remarkable in economical benefits improves.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment.For those skilled in the art, do not departing from the improvement that obtains under the utility model technical conceive prerequisite and conversion also should be considered as protection domain of the present utility model.
