Problems solved by technology

Due to the complex process, it is easy to cause quality problems and delay the construction period
Especially for high-supported concrete floors, the traditional method is to build a full hall frame under the post-casting belt, and then install the supporting formwork. The formwork is installed by hoisting, that is, brackets are installed on the concrete on both sides of the post-casting belt, and then the formwork is lifted to the bottom of the post-casting belt by a lifting device, the formwork is connected to the support, and the upward binding force is generated on the formwork by the support to realize The purpose of fixing the formwork below the post-casting belt, but the above-mentioned method cannot quickly connect the formwork to the bracket above the post-casting belt due to the height of the post-casting belt and the lower ground, resulting in low construction efficiency

Embodiment 1

[0042] The present invention is based on the construction method of building post-pouring belt, comprises the following steps:

[0043] 1) Install the support frame 5 on the concrete 1 on both sides of the pouring belt 9 to be poured;

[0044] 2) Connect the moving block 10 to the support frame 5, so that the horizontal plate 6 is installed above the pouring belt 9 after pouring;

[0045] 3) Connect the threaded rod 8 connected to the template 3 with the horizontal plate 6 through the nut 7;

[0046] 4) Rotate the nut 7, and the threaded rod 8 drives the formwork 3 to move downward in the vertical direction, so that the formwork 3 passes through the pouring belt 9 to reach the bottom of the pouring belt 9;

[0047] 5) Build a ladder on the lower floor of the concrete 1, the construction workers climb up the ladder, unfold the two folded movable support plates 2, and ensure that the formwork 3 is flush with the movable support plates 2;

[0048] 6) Use the movable block 4 to ...

Embodiment 2

[0056] On the basis of Embodiment 1, the fixed assembly includes a rotating rod 12, two first connecting blocks 15, and two moving plates 11. The first connecting blocks 15 are respectively located on both sides of the axis of the template 3, and the rotating rod 12 The two ends of the two first connecting blocks 15 are respectively connected, and the rotating rod 12 can rotate in the first connecting block 15, the moving plate 11 is located at the bottom of the template 3, and the moving plate 11 runs through the first connecting block horizontally 15, the rotating rod 12 is rotated, and the moving plate 11 can move horizontally in the connecting block. The two ends of described rotating bar 12 are all provided with movable block 4, and movable block 4 is connected with rotating bar 12 by screw thread, and described movable block 4 is all provided with connecting rod 14, and connecting rod 14 is connected with moving plate 11, movable When the block 4 moves on the rotating ro...

Embodiment 3

[0058] On the basis of Embodiment 2, two connecting grooves 22 are provided at both ends of the template 3, and two connecting grooves 22 matching the connecting grooves 22 are provided on the side wall of the movable support plate 2 facing the template 3. Two connecting blocks 23, the second connecting block 23 is located in the connecting groove 22, the movable shaft 17 is also provided in the connecting groove 22, and the movable shaft 17 is inserted in the second connecting block 23, the second connecting block 23 can move Rotate on axis 17.

Abstract

The invention discloses a construction method based on post-pouring belts of a building. A supporting frame arranged on concrete is included, the supporting frame is provided with a plurality of transverse plates, the transverse plates are distributed along the post-pouring belts on the supporting frame, each transverse plate is provided with a threaded rod and a nut, the threaded rods can move in the vertical direction on the transverse plates, and the nuts are connected with the threaded rods and located at the tops of the transverse plates; and templates are arranged at the bottoms of the threaded rods, the threaded rods are further provided with cap nuts, the cap nuts are located at the bottoms of the templates, the templates are detachably connected with the threaded rods, the lengths of the templates are less than the widths of the post-pouring belts, movable supporting plates are arranged on both sides, in the direction of facing the concrete, of the templates correspondingly, the movable supporting plates are hinged to the templates correspondingly, and the movable supporting plates can be rotated on the templates; and fixing assemblies are further arranged at the bottoms of the templates, and the fixing assemblies can make the upper surfaces of the movable supporting plates and the upper surfaces of the templates be on the same horizontal line.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method based on building post-cast belts. Background technique [0002] The post-cast belt is to prevent the harmful cracks that may occur in the cast-in-place reinforced concrete structure due to temperature, uneven shrinkage, and settlement deformation during construction. According to the requirements of design or construction specifications, temporary The construction joint temporarily divides the structure into several parts, and after a certain period of time, the concrete of the construction joint is poured and tamped after the internal shrinkage and settlement deformation of the components to connect the structure into a whole. In the construction of building structures, the construction of the post-pouring belt of the concrete slab is a very important link. Due to the complex process, it is easy to cause quality problems and delay the constr...
