Abstract
The utility model belongs to the technical field of architectural construction and particularly relates to a connecting piece for a scaffold and a building. The utility model discloses a pre-embedded piece for a wall connecting component, which comprises a bolt sleeve, a nut, an end cover and an end plug; and the bolt sleeve comprises a hollow rod part and a head part, wherein the end plug is matched with the end surface of the head part of the bolt sleeve in a sealed manner, the nut is arranged in the head part of the bolt sleeve, and the end cover is matched with the end surface of the rod part of the bolt sleeve in a sealed manner. The pre-embedded piece made of plastic as the main material greatly saves the construction cost while ensuring the connection strength, is convenient for construction operation, has no influence to the normal construction procedure and reduces the leakage probability due to the small holes on the wall surface.
Description
Technical field
The utility model relates to technical field of building construction, refers more particularly to the connector of a kind of scaffold and building.
Background technology
Wall-connecting piece is the member that connects scaffold and building.Scaffold is that the job site is that the operating personnel solves various supports vertical and that the level transportation is set up, is building when building, and scaffold need be fixed by wall-connecting piece and body of wall, so that scaffold is played firm effect, prevents that scaffold from rocking or topple over.The structure of wall-connecting piece firmly plays a key role to scaffold.
Chang Yong wall-connecting piece was a default steel pipe perpendicular to floor on the reinforced frame of building floor beam slab face in the past, buckled with the drawknot bar of fastener with steel pipe and scaffold again, cast afterwards.The unfavorable factor of the method is: every drawknot point all will be buried steel pipe and fastener underground, and not recyclable, and steel pipe, fastener material consumption are big, the cost height.And after using, because the drawknot bar will stay bigger hole at body of wall, the potential risk that there is infiltration in building and leaks, though there are many obstruction schemes the construction technology aspect, but the strictness that often is difficult to the scheme that guarantees in practice of construction is implemented, thereby the seepage that causes thus will have a strong impact on the result of use of building.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of built-in fitting of wall-connecting piece, and built-in fitting can be installed on the template easily, and the dismounting built-in fitting is convenient, and cost is low, and is easy to use and be difficult for causing seepage.
For solving the problems of the technologies described above, the utility model is taked following technical scheme:
The built-in fitting of wall-connecting piece, comprise bolt sleeve, nut, end cap and end plug, described bolt sleeve comprises the bolt sleeved rod portion and the bolt sleeve head of hollow, and nut is built in the bolt sleeve head, end plug and bolt sleeve head end are sealed and matched, and end cap and bolt sleeved rod portion are sealed and matched.Because these built-in fitting two ends all seal, concrete can not enter into bolt sleeve, can not influence later connection.
As preferably, described bolt sleeved rod portion is that cylindrical, described nut is the hexagon column.In order to make nut be built in the bolt sleeve head, the external diameter of nut is slightly less than the internal diameter of bolt sleeve head and greater than the internal diameter of bolt sleeved rod portion.
As preferably, described bolt sleeve, nut, end cap and end plug are coaxial.
As preferably, described end cap inner surface has plug in the end cap, and plug is sealed and matched with bolt loop bar end surface in the end cap.
As preferably, the internal diameter of described bolt sleeved rod portion is 1cm-2cm.Such internal diameter setting can make the bolt of follow-up use satisfy requirement of strength and the hole that stays at metope less.
As preferably, described bolt loop bar minister degree is 6cm-10cm.The requirement that this length can satisfy thickness of wall body can make tensile strength bigger again.
The utility model does not need to bury steel pipe and fastener underground, when having guaranteed bonding strength by the improvement of wall-connecting piece built-in fitting, saved construction cost greatly, and constructing operation is convenient, does not influence the normal construction program, the hole of metope is very little, has reduced the probability of seepage.

Specific embodiment
Below in conjunction with the accompanying drawing 1-7 and the specific embodiment the utility model is described in further detail:
The sequence number of each parts and title among the figure: plug 7, prefab form 8, screw 9, bolt 10, steel disc 11, drawknot bar 12, pole steel tube 13, fastener 14 in bolt sleeve 1, nut 2, end cap 3, end plug 4, bolt sleeved rod portion 5, bolt sleeve head 6, the end cap.
Shown in accompanying drawing 1,2,3, the built-in fitting of wall-connecting piece comprises bolt sleeve 1, nut 2, end cap 3, end plug 4; Bolt sleeve 1 comprises the bolt sleeved rod portion 5 and bolt sleeve head 6 of hollow, and bolt sleeved rod portion 5 be that cylindrical, bolt sleeve head 6 is the hexagon column for hexagon column, nut 2.Bolt sleeved rod portion 5 length are 7cm, and the internal diameter of bolt sleeved rod portion 5 is 1.2cm, and the length of bolt sleeve head 6 is 2cm, and the internal diameter of bolt sleeve head 6 is 2.5cm, and the external diameter of nut 2 is 2.2cm, and the external diameter of end plug 4 is for being 2.5cm, and the external diameter of plug 7 is 1.2cm in the end cap.The material of described bolt sleeve, end cap and end plug is plastics.
Shown in accompanying drawing 4,5, in pre-buried operation, that side that end cap 4 external surfaces and the wooden form 8 of this wall-connecting piece built-in fitting needs casting concrete is fixed earlier with screw 9, fill in 7 in the bolt sleeved rod portion 5 insertion end caps with bolt sleeve 1 again, at this moment, plug 7 is sealed and matched with bolt sleeved rod portion 5 end faces in the end cap, then nut 2 is put into bolt sleeve head 6, end plug 4 will be put into bolt sleeve head 6 sealings of nut 2, and at this moment, described bolt sleeve 1, nut 2, end cap 3 and end plug 4 are coaxial.Afterwards, can carry out normal concrete casting, the wall-connecting piece built-in fitting has suffered to body of wall with regard to pre-buried.
When needing to carry out the scaffold connection by the time, wooden form 8 is taken off, also can extract simultaneously plug 7 in the end cap, at this moment, body of wall just exposes the cavity of bolt sleeved rod portion 5, uses the bolt 10 of length greater than bolt sleeve 1 length, can bolt 10 and nut 2 is fastening, it is fastening with nut 2 that bolt 10 is passed a firm sheet 11, and then steel disc 11 tightens together with bolt 10 and the nut 2 that is embedded in the wall, as shown in Figure 6.Steel disc 11 also just is fastened on the metope.Drawknot bar 12 1 ends and steel disc 11 are welded, and the other end of drawknot bar 12 and pole steel tube 13 carry out snapping by fastener 14, and whole scaffold just promptly firmly has been connected with building wall, as shown in Figure 7.
When needing to tear scaffold open by the time, bolt is screwed out bolt sleeve 1, drawknot bar 12 promptly separates with body of wall with steel disc 11, and bolt 10 and steel disc 11 also can reuse, and metope only stays the hole of the cavity 1.2cm size of bolt sleeved rod portion 5.
The material of described bolt sleeve, end cap and end plug is plastics.The very cheap and good airproof performance of cost.
Though described embodiment of the present utility model in conjunction with the accompanying drawings, those skilled in the art can make various distortion or modification within the scope of the appended claims in this area.
