Abstract
The invention relates to a method for pouring a reinforced concrete beam of an operating platform, comprising a short column (1) used as a foundation for a steel column and a platform beam (4), wherein the short column (1) used as the foundation for the steel column is provided with preformed holes (2) in which steel dowels (3) are arranged in advance; the preformed holes (2) are used as a hinged support for the platform beam (4); steel bars in the platform beam (4)are caused to extend into the preformed holes (2); and the operation of pouring concrete is carried out. The invention avoids high difficulty in construction, which is generated due to the adoption of the traditional design method, and the design method achieves considerably simple and convenient construction.
Description
Technical field
The present invention relates to a kind of casting method of steel concrete operating platform beam.
Background technology
In the steel work industrial premises, because the needs on using often need be established one deck cast-in-situ steel reinforced concrete operating platform.
Fig. 1 is the schematic diagram of available technology adopting conventional method design, 1 ' is the short column on steel column basis, workshop among the figure, 2 ' is the vertical reinforcing bar of short column on steel column basis, 3 ' is steel column, 4 ' is the steel column foot crab-bolt, 5 ' is steel column foot shear key preformed hole, and 6 ' is cast-in-situ steel reinforced concrete operating platform beam, and 7 ' is the negative muscle of landing beam back.As can be seen, adopt this method because landing beam is fixed the connection with the short column on steel column basis, so the negative muscle of landing beam back is more, easily make the negative muscle of landing beam back bump the vertical reinforcing bar of short column, steel column foot crab-bolt and the steel column foot shear key on steel column basis, need bar bending is escaped for the negative muscle of back can be passed, increased difficulty of construction like this.
Summary of the invention
Technical problem to be solved by this invention provides a kind of casting method of steel concrete operating platform beam, and this method makes construction more convenient, and landing beam is stressed clear and definite.Weak point such as cause constructional difficulties to overcome traditional design method, waste time and energy.
In order to solve the problems of the technologies described above, the present invention has taked following technical scheme: preformed hole on the short column on steel column basis, workshop, in preformed hole, reserve joint bar, and preformed hole is as steel concrete operating platform beam pivoting support, reinforcing bar stretches into preformed hole and satisfies anchorage length, concreting in the beam.
The width of preformed hole is the width of landing beam.
Compared with prior art, the present invention has avoided adopting the big shortcoming of traditional design method difficulty of construction, adopts the construction of the design's method convenient.
Description of drawings
Fig. 1 is the schematic diagram of traditional design method;
Fig. 2 is a floor map of the present invention;
Fig. 3 is the A-A sectional view among Fig. 2;
The specific embodiment:
Embodiment 1: the casting method of steel concrete operating platform beam of the present invention is as follows:
The first, on the short column 1 on steel column basis, workshop, establish preformed hole 2, the preformed hole width is the width of operating platform beam 4, and length is 300mm, and the degree of depth is a deck-molding.In preformed hole 2, reserve joint bar 3, is reinforcing bar 2? 8mm, Fig. 2 is seen in its plane signal;
The second, preformed hole 2 is as steel concrete operating platform beam 4 pivoting supports, and reinforcing bar stretches into preformed hole 2 and satisfies anchorage length, concreting in the landing beam 4.Schematic diagram is seen Fig. 3;
By above steps, promptly finished the method for designing that use is articulated and connected in the cast-in-situ steel reinforced concrete operating platform beam of portal frame structure workshop, as can be seen, entire method is very simple and direct.
Claims (2)
1. the casting method of a cast-in-situ steel reinforced concrete operating platform beam, it is characterized in that: on the short column (1) on steel column basis, preformed hole (2) is set, in preformed hole (2), reserve joint bar (3), preformed hole (2) is as the pivoting support of landing beam (4), the interior reinforcing bar of landing beam (4) stretches in the preformed hole (2), concreting.
2. the casting method of steel concrete operating platform beam according to claim 1 is characterized in that: the width of preformed hole (2) is the width of landing beam (4).
