Detailed Description
The invention is explained in detail below with reference to the accompanying drawings:
as shown in fig. 1-6: an assembled side formwork system for a prestressed hollow slab floor system comprises
The prefabricated beam 3 is a beam structure extending in the front-back direction, and a plurality of through holes 4 extending in the left-right direction are formed in the beam structure;
the outer diameter of the transverse supporting steel pipe 5 is slightly smaller than the aperture of the through hole 4, the transverse supporting steel pipe 5 penetrates through the through hole 4 and is temporarily fixed with the transverse supporting steel pipe 5 through a fastener 5 a;
the longitudinal steel pipe 6 is arranged above the transverse supporting steel pipe 5 and is connected with the transverse supporting steel pipe 5 through a steel pipe fastener 7;
the template is laid above the longitudinal steel pipe 6 and is connected with the longitudinal steel pipe 6 in a detachable mode; for carrying the prestressed hollow slab 1.
Wherein the fastener 5a is a wedge made of wood or rubber.
The following two examples can be derived according to the type of template:
example 1
As shown in fig. 1 and 2: the template is a wooden template 8a, and the wooden template 8a penetrates through the wooden template 8a by adopting a steel wire to be fixed with the longitudinal steel pipe 6.
Example 2
As shown in fig. 3 and 4: the template is a steel template 8b, a clamping piece 9 is fixedly arranged at the bottom of the steel template 8b, and the clamping piece 9 is clamped on the longitudinal steel pipe 6.
And the top of the precast beam 3 is provided with a steel bar extending out of the precast beam 3. Because the later stage involves pouring surface layer concrete, adopt the reinforcing bar of precast beam 3 and prestressing force hollow slab lateral surface to be on the flat front, can ensure that the connection between precast beam 3 and the prestressing force hollow slab 1 forms wholly.
The use method of the assembled side die system comprises the following steps:
step 1: installing a transverse supporting steel pipe 5 in a through hole 4 of the precast beam 3; the fastener 5a is inserted into the gap between the through hole 4 and the transverse supporting steel pipe 5 to realize the fixation of the two;
the precast beam can reserve the through hole 4 in the early production stage without opening in the later production stage.
Step 2: the longitudinal steel pipe 6 is locked on the transverse supporting steel pipe 5 through a steel pipe fastener 7;
and step 3: installing and fixing the template above the longitudinal steel pipe 6;
and 4, step 4: integrally hoisting the precast beam 3 to a specified position, mounting the prestressed hollow slab 1 and pouring surface layer concrete 2;
and 5: and after the surface concrete 2 meets the design strength requirement, removing the fasteners 5a5a, loosening the steel tube fasteners 7, knocking out the transverse supporting steel tubes 55 from one side to the other side of the precast beam 3, and naturally removing the longitudinal steel tubes 6 and the template.
