Abstract
A transverse expansible bridge inner form truss segment comprises left and right truss segments which are symmetric. Each of the left and right truss segments comprises upper beams and lower beams. Support pillars are connected between the upper beams and the lower beams. The inner ends of the upper beams and the inner ends of the lower beams are provided with upper bolt holes and lower bolt holes. The middle of the upper beams and the middle of the lower beams are provided with upper bolt slots and lower bolt slots. The upper and lower bolt holes of the left and right truss segments match with the upper and lower bolt slots on the opposite side respectively. The support pillars include vertical pillars and diagonal pillars. The transverse expansible inner form truss segment is adaptive to width change of beam roofs and is simple in structure, multifunctional, convenient and fast to connect, material-saving and higher in operating efficiency.
Description
Technical field
The utility model relates to a kind of horizontal scalable internal mold of bridge purlin sheet.
Background technology
At present, the width of bridge cantilever pouring beam body top board changes along with the beam body, because concrete roof is thicker, general steel internal mold purlin sheet and the template of adopting is as load-carrying members in construction.And in construction, general internal mold purlin leaf length is fixed, because beam body top board width change needs to make the above internal mold purlin sheet of 2 covers.Construction has high input, and is less economical.
The utility model content
The utility model provides a kind of horizontal scalable internal mold of bridge purlin sheet, and simple in structure, practical function connects very convenient, fastly, has saved material, has improved operating efficiency.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of horizontal scalable internal mold of bridge purlin sheet, the left and right purlin sheet that comprises the shape symmetry, left and right purlin sheet includes top rail and lower transverse beam, between top rail and lower transverse beam, be connected with support column, top rail and lower transverse beam the inner are respectively equipped with upper bolt hole and lower bolt hole, and top rail and lower transverse beam middle part are respectively equipped with bolt slot and lower bolt slot; The upper bolt hole of left and right purlin sheet and lower bolt hole cooperatively interact with the other side's upper bolt slot and lower bolt slot respectively.
Support column comprises right cylinder and oblique column.
But the utility model is by realizing the internal mold purlin sheet of transversal stretching, and adapting to beam body top board width change, simple in structure, practical function connects very convenient, fastly, has saved material, has improved operating efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of left purlin sheet;
Fig. 3 is the structural representation of right purlin sheet.
The specific embodiment
Embodiment: as Figure 1-3, a kind of horizontal scalable internal mold of bridge purlin sheet, comprise the left purlin sheet 12 of shape symmetry, right purlin sheet 13, left purlin sheet 12, right purlin sheet 13 include top rail 5,14 and lower transverse beam 1,15, top rail 5,14 and lower transverse beam 1,15 between be connected with support column 3, support column 3 comprises right cylinder and oblique column.Top rail 5,14 and lower transverse beam 1,15 the inners be respectively equipped with upper bolt hole 5,8 and lower bolt hole 2,9, top rail 5,14 and lower transverse beam 1,15 middle parts be respectively equipped with bolt slot 6,10 and lower bolt slot 7,11; The upper bolt hole 4 of left purlin sheet 12 and lower bolt hole 2 cooperatively interact with upper bolt slot 10 and the lower bolt slot 11 of right purlin sheet 13 respectively.The upper bolt hole 8 of right purlin sheet 13 and lower bolt hole 9 cooperatively interact with upper bolt slot 6 and the lower bolt slot 7 of left purlin sheet 12 respectively.
When construction the widest top board place, the purlin sheet splices, with bolt hole 8,9 and bolt slot 6,7 low order end be bolted, bolt hole 2,4 and bolt slot 10,11 high order ends be bolted.Four bolts connect into a stressed integral body with left purlin sheet 12 and right purlin sheet 13.To realize the transversal stretching of purlin sheet, satisfy beam body top board wide variety to the requirement of purlin sheet.
Claims (2)
1. horizontal scalable internal mold of bridge purlin sheet, it is characterized in that: the left and right purlin sheet that comprises the shape symmetry, left and right purlin sheet includes top rail and lower transverse beam, between top rail and lower transverse beam, be connected with support column, top rail and lower transverse beam the inner are respectively equipped with upper bolt hole and lower bolt hole, and top rail and lower transverse beam middle part are respectively equipped with bolt slot and lower bolt slot; The upper bolt hole of left and right purlin sheet and lower bolt hole cooperatively interact with the other side's upper bolt slot and lower bolt slot respectively.
2. horizontal scalable internal mold of bridge according to claim 1 purlin sheet is characterized in that: support column comprises right cylinder and oblique column.
