For the convenience of understanding the above technical solutions of the present invention, the above technical solutions of the present invention are explained in detail through specific use modes below.
The embodiment of the utility model provides a atress mode that is used for template and ordinary plank sheathing technology of expansion joint department roughly the same, bear by materials such as wood-cement board, steel pipe, wooden fossil fragments, split bolt, the difference lies in: the template adopts a self-made fixing piece to penetrate through the wood veneer panel to connect other materials into a whole, can be directly integrally hoisted to a designated position, and can not generate the phenomenon of scattering. Can directly penetrate when indoor structure opposite side template installation and fix with this template split bolt, once only install in place, can have enough to meet the need the use, greatly reduced construction cost need not to get into in the expansion joint and just can accomplish all ann and tear the process open. The embodiment of the utility model provides a concrete preparation and application method for template of expansion joint department as follows:
1) matching die
The stress calculation of the common wood template process is carried out according to the structural form in the design drawing, the structural requirements of the thickness of the wood veneer 1, the selection of the primary and secondary keels, the diameter and the distance of the split bolt 9 and the like are obtained, and the following three points need to be paid attention during processing:
the construction of the expansion joint of the basement is consistent with the method for matching the formwork in the common wood formwork process when the size of the formwork is machined.
Secondly, a basement exists in a new construction, and when the construction is carried out on the ground, the template processing needs to be heightened according to the height of the size of the component: component height + floor thickness + board bottom apart from the vertical interval of the uppermost part split bolt of basement +200mm, if: the height of the ground layer component is 4500mm, the thickness of the floor slab is 180mm, the vertical distance between the bottom of the slab and the uppermost part of the basement is 300mm, and the processing height of the template is 4500+180+300+200=5180 mm.
The function of the raised bottom portion 14 is: when the above-ground structure is constructed, the template at the expansion joint is suspended in the air, the bolt holes reserved at the bottom and the structural bolt holes constructed at the lower layer are inserted and fixed, and the flatness of the joint of the new concrete and the old concrete and the stability of the bottom of the template are guaranteed. The bolt fixing position of the inner wall of the lower layer structure can be directly fixed by adopting double steel pipes, a mountain-shaped clamp and a nut without using a wood veneer and a batten.
Thirdly, reserving the split bolt holes: the height of the lowest row of bolts from the bottom is 200mm, the horizontal distance and the vertical distance of a first 12 bolt holes of a common stressed template system are determined according to stress calculation (the horizontal distance and the vertical distance are both 450mm in the embodiment), and the size of a first 12 bolt holes is as follows: the diameter of the split bolt is +2mm, and the split bolt and the wall-penetrating PVC pipe are mounted. In addition, on the basis of the distance, a second part of bolt holes 13 is added: the position of each transverse main keel at a vertical interval needs to be set (450 mm), the horizontal interval is 900mm, and the diameter of the hole of the second bolt hole 13 is equal to that of the bolt.
2) Fastener manufacturing
Cutting phi 14 split bolts to manufacture the harness cord bolts (namely bolts 8), wherein the length of the outer rods of the bolts 8 is changed along with the thickness change of materials such as wood veneer boards, battens, steel pipes and the like, and the conventional length is about 200 plus 250mm, and the conventional length is welded with a steel plate 7 with the thickness of 100mm multiplied by 3mm to form an anchor bolt, namely a fixing piece 6.
3) Mounting of fixtures
And inserting the bolts 8 on the fixing piece 6 into the bolt holes II 13 from one side of the prepared template, flatly placing the bolt on the ground, installing all the main keels and the auxiliary keels on the other side according to the structural requirements, aligning the mountain-shaped clamps 4 with the bolts 8 extending out of the bolt holes II 13 of the template, screwing the nuts 5 in the bolts, namely, enabling the fixing piece 6 to penetrate through the 15mm thick wood-glue board, the 50 x 100mm batten, the phi 48 x 3.5mm steel pipe, the mountain-shaped clamps and the nuts from the reserved holes to be combined to form the shaping template.
4) Welded nut and mountain-shaped clamp
At the reserved bolt hole, the hole between the mountain-shaped clamp 4 and the nut 5 is superposed and aligned with the hole, the nut 5 is welded on the mountain-shaped clamp 4, and then the mountain-shaped clamp 4 is welded on the main keel (double steel pipe) 3 so as to penetrate the bolt from the inner side of the structure for fixing.
5) Hook welding
And the top steel pipe adopts a round 20 steel bar welding lifting hook, and the template of each single piece is welded with two lifting hooks, so that the lifting and hoisting are facilitated.
6) Anti-rust paint for painting
All welded parts are coated with anti-rust paint to prevent damage caused by rusting, so as to ensure long-term use.
7) Hoisting device
With self-control template hoist and mount assigned position, at first during the installation with the template bottom increase bolt hole in the 14 scopes of part and bolt hole on the substructure use the split bolt to fix, during the inboard template of installation, need aim at and move just inside and outside bolt hole position, penetrate a pair of whole template system of bolt hole with PVC pipe and split bolt from the inboard and fix can.
The reserved bolt hole I12 in the figure 1 is used for reinforcing a template system (the same as a common template process), a hole in the middle of the mountain-shaped clamp 4 and the nut 5 is aligned with the hole in a superposition mode at the reserved bolt hole I12, the nut 5 is welded on the mountain-shaped clamp 4, and then the mountain-shaped clamp 4 is welded on a main keel (a double-steel pipe) so as to penetrate a bolt from the inner side of a structure for fixing and bear the force of the structure during concrete pouring; the second bolt hole 13 (where the fixing piece passes) is used for fixing the square beam, the steel pipe beam and the template to form a shaping whole, so that the frame is prevented from being scattered.
In conclusion, with the aid of the technical scheme of the utility model, the template for expansion joints is convenient to construct, the template can be directly connected and fixed from one side for a structure with small space and no operation space, the operation is simple and convenient, the construction time is shortened, the safety of operators is effectively guaranteed, and the construction safety is improved; the template is formed by combining common materials on a construction site, so that the materials and labor are greatly saved; the template is convenient to mount and dismount, can be directly manufactured on site, is high in production speed and low in price, can be repeatedly used, and greatly reduces the cost; the template is not easy to deform and firm to install, can effectively improve the forming quality of components, ensures the normal and effective structure functions, and avoids influencing the service life of a building.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
