Description
Technical field
The present invention relates to a kind of comprise board and with the mounting plate of the fastening anchoring section of described board, described mounting plate before hardening of concrete, be arranged in concrete and and then utilize concrete sclerosis to be fastened in concrete, wherein by the threaded portion by described anchoring section and being threaded of being arranged on that the hole with internal thread in described board provides each anchoring section and described board is fastening.
Background technology
Nowadays various mounting plates are well-known in builing industry.Mounting plate is will be fastened on the element in concrete before hardening of concrete.Mounting plate is by making such as suitable materials such as steel.According to prior art, anchoring section is fastening with suitable mode and board, for example, by anchoring section being welded on the plate face or being welded in the hole that extends through plate.Being threaded, it is fastening also to be used to anchoring section and board.Mounting plate is arranged in concrete, makes anchoring section stretch in concrete, and the external surface of board is positioned on concrete surface.In concrete hardening process, mounting plate and concrete joint are combined.
The purposes of mounting plate is to realize that power and load that a kind of permission will be caused by different structure are delivered to concrete structure.After hardening at concrete, structural fasteners is fastened on the board of concrete surface, realizes said structure.For example, this fastening can be by directly being welded on board and realizing.Therefore, different structure can be fastened on the said structure securing member, and can realize that a kind of power that different structure can be caused and load are delivered to concrete structure via mounting plate.
There are some practical problems in the solution of prior art.When using prefabricated mounting plate, wherein by welding fastening anchoring section, problem is, if concrete structure has a large amount of reinforcing bars, is difficult to so in many cases or sometimes even each plate may be arranged on the tram separately in concrete structure.Another shortcoming be welded to connect is, is welded to lip-deep anchoring section and can on board, causes extra stress, thereby board is produced to extra requirement.
In the situation that welded construction has problems, nature can be used the solution of mounting plate, and wherein anchoring section is threaded connection with board fastening.The shortcoming of this solution is, at the construction field (site) under condition, usually is difficult to guarantee the appropriate operation of the screw thread that is threaded.Anchoring section fastening bad may jeopardize mounting plate and the fastening whole process of concrete.
Summary of the invention
The object of the present invention is to provide a kind of mounting plate, utilize this mounting plate can eliminate shortcoming of the prior art.Realized this point by mounting plate according to the present invention.Mounting plate of the present invention is characterized in that described anchoring section comprises the extension of extending from described threaded portion, and the hole in described board is provided with the groove that forms the circumference concentric with described hole, the inner surface of described groove is configured to consist of the flange part around described hole, when described flange part is configured in the internal thread in the hole in the threaded portion of described anchoring section is tightened to described board, described flange part flexing cover described groove under the impact of described extension.
Importantly, the invention has the advantages that, the formation be threaded for control provides visual help; That is to say, the present invention can be easily and fully tightening of guaranteeing simply to be threaded at the construction field (site), thereby contribute at the construction field (site) the enforcement of anchoring under condition.The present invention even allows each anchoring section is screwed on the tram separately of reinforcing bar inside.Compare with the mounting plate structure of using welding in advance, more independent board and anchoring section are transported to job site, and easily in transportation and process at the construction field (site) them.Another advantage of the present invention is its simplicity, and this is conducive to the present invention and is used.
The accompanying drawing explanation
Embodiment below by describing in accompanying drawing, illustrate in greater detail the present invention, in the accompanying drawings:
Fig. 1 be illustrate the mounting plate that engages with concrete structure and with the stereoscopic principal figure of the fastening structural fasteners of mounting plate,
Fig. 2 illustrates the schematic diagram of mounting plate of the present invention from a side,
Fig. 3 illustrates the schematic diagram of the mounting plate shown in Fig. 2 from another direction, and
Fig. 4 shows the details A in Fig. 2 with magnification ratio.
The specific embodiment
Fig. 1 illustrates the principle of the mounting plate engaged with concrete structure 1.This mounting plate comprises board 2 and anchoring section 3.Structural fasteners 10 is fastened on board 2.Anchoring section 3 for example can or be threaded fastening with board 2 by welding.Before concrete becomes dry, mounting plate is arranged in concrete, and in hardening of concrete, mounting plate is fastened in concrete thus.
Be shown in broken lines concrete structure 1 and structural fasteners 10 in Fig. 1.Concrete structure 1 can be any known structure.Therefore, structural fasteners can be known any structure itself.For example, the different structure element of building can be fastened on structural fasteners 10, and the power that will be caused by these structural members thus and load are delivered to concrete via mounting plate.These facts are known for those skilled in the art, thereby here they are not illustrated in greater detail.
To those skilled in the art, this belongs to routine techniques fully, thereby here is not described in more detail.
Fig. 2～4 illustrate an embodiment of mounting plate of the present invention.In Fig. 2～4, adopt the Reference numeral identical with Fig. 1 to mean corresponding parts.
In the embodiment shown in Fig. 2～4, anchoring section 3 is fastening with board 2 by being threaded.Be threaded and comprise the threaded portion 4 be arranged on anchoring section 3 and be arranged on the hole with internal thread 56 in board 2.
According to basic conception of the present invention, anchoring section 3 comprises 4 extensions 7 of extending from threaded portion.Extension 7 is configured such that its forms the extension of threaded portion, thereby when the free end from anchoring section 3 during towards board 2 observation, this extension is positioned at the front of threaded portion 4.Around the hole with internal thread 6 be located in board, be provided with form with hole 6 concentric but be greater than the groove 8 of the circumference in hole 6.The inner surface of groove 8 is configured to consist of the flange part 9 in the hole 6 around having internal thread, this flange part is configured to when the threaded portion 4 of anchoring section is tightened in the screw thread in the hole 6 in board, and this flange part is with predetermined way flexing (yield) under the impact of extension 7 of expectation.
Therefore, design of the present invention is, when screwing anchoring section 3 and tighten in hole 6, start to make flange part 9 distortion in a certain extension 7 of tightening the stage, so flange part 9 flexings (that is, radially outward crooked), make groove 8 be capped in a certain stage of tightening.Produced so visible fixed mechanism, thereby shown and guarantee that anchoring section is fixed on board 2 rightly with practical way.
Preferably, around hole, 6 groove 8 is 6 continuous grooves that extend around hole.The advantage of groove is continuously, has realized continuous flange part 9 along whole distance, and has utilized the suitable degree of tightening, and flange part 9 is capped along whole range curvature and whole groove.Even under difficult job site condition, also this situation can easily be detected.
The above embodiment of the present invention does not limit the present invention in any way, and on the contrary, in the protection domain of claims, can fully freely change the present invention.For example, according to different situations, can freely change shape and the size of board.Therefore, according to different situations, can freely change the quantity of anchoring section and size etc.
