Embodiment 1

[0074] Embodiment one sees Figure 1-3 , Figure 6-10 , Figure 15-19 As shown, a glass fiber cement non-demolition formwork system includes a group of panel groups spliced ​​by panel units 1 , a supporting frame structure at the back of the panel group and tension bolts 2 .

[0075] The panel unit 1 is a glass fiber reinforced cement board. In this embodiment, the size is length × width × thickness = 1200mm × 2400mm × 30mm. The inner surface of the panel unit 1 is provided with transverse interlocking reinforcing grooves 1.1 arranged at intervals. The size of the reinforced groove cross section is length×width=60mm×8mm, which is used to increase the bite force between the glass fiber cement board and the poured concrete. A vertical connection rib groove 1.2 is respectively provided on the outer surface of the panel unit at a distance of 30mm from the vertical edge, and the vertical connection rib groove 1.2 is arranged along the height direction of the panel unit.

[0076]...

Embodiment 2

[0089] Embodiment two see Figure 1-2 , Figure 4 , Figure 6-12 , Figure 15-19 As shown, different from the first embodiment, the cross-board connection assembly further includes at least one additional one-way cross-board fastener 8 between adjacent one-way cross-board connectors 5 . The one-way cross-slab fasteners are longitudinally arranged at intervals with the one-way cross-slab connectors, which play a role in connecting the frame steel strip and the panel unit.

[0090] The one-way cross-board fastener 8 is a "several"-shaped steel plate, including a second one-way main board 8a and two second one-way wing plates 8b symmetrically fixed on the inner two ends of the second one-way main board 9a, The distance between the two second one-way flaps 8 b is adapted to the width of the frame steel strip 3 , and the thickness of the second one-way flaps 8 b is the same as that of the frame steel strip 3 .

[0091] The second one-way main board 8a is provided with a second ...

Embodiment 3

[0092] Embodiment three see Figure 1-2 , Figure 5 , Figure 6-19 As shown, the difference from Example 2 is that although the formwork without dismantling is generally based on large sizes, if special parts or special process requirements are encountered and two or more layers of formwork are required to be spliced ​​vertically, the panel The unit may include sub-unit boards 1a spliced ​​up and down, and the direct horizontal joints of the sub-unit boards 1a may be bound with galvanized iron wires arranged at intervals of less than 100mm.

[0093] A two-way cross-board connector 9 is also added at the splicing position of the sub-unit board 1a. The two-way cross-board connector 9 is a "several"-shaped steel plate, including a two-way main board 12a and symmetrically fixed on both ends of the two-way main board 9a. Two two-way wing plates 9b, the two-way main board 9a has a two-way main board connection hole 9c and is fastened to the outer surface of the frame steel belt 3 ...

Abstract

The invention discloses a glass fiber cement non-removal formwork system, a connection structure and a construction method of the connection structure. The formwork system comprises a panel group, a support frame structure and a split bolt, wherein transverse interlocked strengthening grooves are formed in the inner side surface of a panel unit at intervals; the support frame structure comprises a frame steel sheet strip, a cross-panel connection assembly and a telescopic panel-attached brace; the frame steel sheet strip is arranged in a full length along the height direction of the panel unit; the cross-panel connection assembly comprises a one-way cross-panel connector; and the split bolt passes through the one-way cross-panel connector and tightens the formwork system from front to back. The connection structure comprises a floor, a formwork bottom locating assembly, a formwork top locator and the glass fiber cement non-removal formwork system. The glass fiber cement non-removal formwork system is simple in form, relatively large in combination rigidity, high in manufacturing accuracy, tight in seam, safe and reliable in structure, good in overall performance, relatively high in turnover frequency, energy-saving and environment-friendly. According to the connection structure and the construction method thereof, the construction efficiency of formwork engineering is improved and the construction cost is reduced.

Description

technical field [0001] The invention belongs to formwork engineering, in particular to a glass fiber cement dismantling-free formwork system in a mixed structure system, a connection structure and a construction method for a composite wall thereof. Background technique [0002] The traditional building formwork is a temporary support structure made according to the design requirements, so that the concrete structure and components are shaped according to the designed position and geometric size, and bear the self-weight of the building formwork and the external load acting on it. The implementation of formwork engineering is an important process to ensure the quality of concrete engineering and construction safety, speed up construction progress and reduce engineering costs. For light steel truss systems, steel columns and steel beams are generally used. The form work is also the process of formwork production or type selection, positioning, support, and dismantling, that is...
