Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an early dismantling jacking structure and a building template system. Background Art

[0002] Currently, most construction projects use cast-in-place concrete structures, and the building formwork system provides temporary support for the concrete. When the strength of the concrete reaches the design requirements, the building formwork system is removed.

[0003] In the existing building formwork system, its early-removal jacking structure supports the formwork system simultaneously through the top support plate and the side bracket below. After the building concrete reaches a certain strength, the early-removal nut is rotated downward to drive the side bracket to slide down, and some formwork parts can be removed and reused. However, this spiral structure twisting method has a slow displacement speed and greatly reduces efficiency.

[0004] Therefore be necessary to provide a kind of new early dismantling jacking structure and building template system. Utility Model Content

The side bracket can slide along the axial direction of the upper arm in the guide groove. When the upper arm slides into place along the guide groove, the side bracket is offset in the direction perpendicular to the guide groove, so that the side bracket can be locked with the upper arm.

[0007] Furthermore, the side bracket includes two symmetrical and connected plates, the edges of the plates are bent outward to form flanges, the flanges include straight flanges extending along the width direction of the plates, the guide grooves include lifting grooves and slots, the lifting grooves are arranged in a straight line along the axial direction of the upper arm, and the slots are vertically arranged on the lifting grooves and communicate with the lifting grooves.

[0009] Furthermore, two straight flanges are provided on the plate at intervals along the axial direction of the upper arm.

[0010] Furthermore, the guide groove passes through two opposite outer side walls of the upper arm.

[0011] Furthermore, a retaining rib is protruding from the side surface of the plate which is the same as the straight flange. When the side bracket deviates in the direction of the vertical guide groove until the slot and the guide groove are vertically aligned, the retaining rib abuts against the upper arm.

[0012] Furthermore, a supporting top plate is provided on the top of the upper arm.

[0013] In addition, the utility model also provides a building template system, including the above-mentioned early-dismantling jacking structure.

[0030] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like refer to the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0031] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. Thus, the appearances of the phrase "in one embodiment", "in some embodiments", or "in some embodiments" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0032] Please refer to Figures 1 to 9 As shown, the early dismounting top support structure provided by the present application is used in a building template system, which comprises an upper arm 1, a side bracket 2, a lower arm 5 and a screw rod 6. The screw rod 6 is installed on the upper arm 1 and is threadedly connected with the lower arm 5. The lower arm 5 is used to be installed on a support keel, so that the lower arm 5 is fixed relative to the ground. Thus, the upper arm 1 can produce linear displacement relative to the lower arm 5 through rotation to realize height adjustment of the upper arm 1. A guide groove 4 is arranged on the upper arm 1 in the axial direction of the upper arm 1. The side bracket 2 can slide in the guide groove 4 along the axial direction of the upper arm 1. When the upper arm 1 is slid in the guide groove 4 to the right position, the side bracket 2 is offset in the direction perpendicular to the guide groove 4, so that the sliding of the side bracket 2 in the guide groove 4 is locked. Thus, when it is needed to move the side bracket 2 downward and release the support of the side bracket 2 to the template support system above, the side bracket 2 is only needed to be offset and reset in the direction perpendicular to the guide groove 4, so that the sliding of the side bracket 2 in the guide groove 4 is restored. The side bracket 2 can be quickly moved downward to release the support of the side bracket 2 to the template support system. Compared with the screw thread connection mode in the prior art, the operation is fast and the work efficiency is effectively improved.

[0033] As shown in Figure 6 and Figure 7 In some embodiments, the side bracket 2 comprises two symmetrical and connected plate blocks 21. The edges of the plate blocks 21 are outwardly bent to form flanges 3. The flanges 3 comprise straight flanges 31 extending in the width direction of the plate blocks 21. Figure 3 and Figure 4As shown, the guide groove 4 comprises a lifting groove 41 and a slot 42, the lifting groove 41 is linearly arranged along the axial direction of the upper arm 1, and the slot 42 is vertically arranged on the lifting groove 41 and communicates with the lifting groove 41. When it is needed to slide the side bracket 2 along the lifting groove 41 to lift, the straight flange 31 on the plate 21 is offset from the lifting groove 41, at this time, the plate 21 can make linear reciprocating motion in the lifting groove 41 along the axial direction of the upper arm 1. When the side bracket 2 moves to the position where the straight flange 31 on the plate 21 is aligned with the slot 42, the plate 21 is offset in the direction of the vertical guide groove 4 until the straight flange 31 is inserted into the slot 42, at this time, the plate 21 cannot slide in the lifting groove 41 due to the effect of the straight flange 31 fitted into the slot 42, thereby achieving the effect of limiting the height of the side bracket 2. The design of the straight flange 31 on the plate 21 helps to improve the vertical bearing capacity of the plate 21.

[0034] As shown in Figure 6 and Figure 7 in some embodiments, a slot 32 is formed on the straight flange 31, when the slot 32 is vertically aligned with the guide groove 4, the thickness of the plate 21 is suitable for sliding into the lifting groove 41, when the straight flange 31 is horizontally aligned with the slot 42, the lateral offset of the side bracket 2 makes the slot 32 vertically deviate from the guide groove 4, at the same time, the straight flange 31 horizontally coincides with the slot 42, that is, the straight flange 31 is inserted into the slot 42, at this time, the straight flange 31 and the slot 42 are vertically inserted and limited, so that the side bracket 2 cannot make lifting movement on the upper arm 1 in the vertical direction.

[0035] As shown in Figure 6 and Figure 7 in some embodiments, two straight flanges 31 are arranged on the plate 21 along the axial direction of the upper arm 1, and correspondingly, the guide groove 4 comprises two slots 42.

[0036] As shown in Figure 5 in some embodiments, the guide groove 4 penetrates through the opposite two outer side walls of the upper arm 1, so that the side bracket 2 can penetrate through the upper arm 1.

[0037] As shown in Figure 6 and Figure 8 in some embodiments, a blocking rib 211 is protruded on the same side of the plate 21 as the straight flange 31, when the side bracket 2 is offset in the direction of the vertical guide groove 4 to the position where the slot 32 is vertically aligned with the guide groove 4, the blocking rib 211 abuts against the upper arm 1, thereby helping to accurately identify the horizontal position of the side bracket 2 and quickly release the inserted and fitted state of the straight flange 31 and the slot 42.

[0038] As shown in Figure 1 in some embodiments, a support top plate 15 is arranged on the top of the upper arm 1, as shown in Figure 9 the support top plate 15 is used to support at least part of the formwork 100.

[0039] As Figure 9 shown, in some embodiments, the template support system includes a template 100, a template main beam 201 and a template secondary beam 202, a plurality of template main beams 201 and a plurality of template secondary beams 202 are supported on the bottom of the template 100, the template secondary beam 202 is built near the template 100, and the template main beam 201 is built on the bottom of the template secondary beam 202. The early disassembly top support structure provided by the embodiment of the present application supports the support top plate 15 on the template 100 by lifting the upper arm 1, and the side bracket 2 is supported on the template main beam 201. When the building concrete on the upper layer of the template 100 reaches a certain strength, the side bracket 2 is lowered, so that the template main beam 201 and the template secondary beam 202 are removed from the side bracket 2, and the early disassembly of the template support system is realized.

[0040] The utility model further provides a building template system, including preceding early disassembly top support structure.

[0041] The above is only the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
