Abstract
The invention relates to a building split bolt, in particular to a one-end-fixing-type split bolt which can be suitable for multi-time turnover, work efficiency can be improved, and material turnover using frequency is improved. The one-end-fixing-type split bolt comprises a screw rod, a butterfly buckle and a nut. Threads are arranged on the screw rod, the number of the butterfly buckle is one, the number of the nut is one, the threads are arranged at one end of the screw rod, the butterfly buckle and the nut are connected in a threading mode at one end, provided with the threads, of the screw rod, one end, far away from the threads, of the screw rod is connected with a fixing rod in a welding mode, the middle portion of the fixing rod and the screw rod are welded, the end of the fixing rod is provided with a bending rod in a connected mode, and the bending rod is arranged on one side, toward the screw rod, of the fixing rod. In construction, the one-end-fixing-type split bolt has the advantages that 50% of butterfly buckles are saved; a fixing end is used for replacing a butterfly buckle and a nut, slipping is avoided, and construction quality is good; loss of construction small materials is saved by about 50%; and the fixing end is inserted into a wall, so that during disassembling, manpower is saved, and construction efficiency is improved.
Description
Technical field
The present invention relates to a kind of building split bolt, be specially adapted to the split bolt that can repeatedly have enough to meet the need, can improve work efficiency, improve material turnover access times.
Background technology
In the epoch of the vertical woods of current highrise building, what shear wall structure was highrise building is leading.When carrying out Shear Wall Structure Construction, the effect of split bolt, performs meritorious deeds never to be obliterated.In engineering practice of construction process, a kind ofly can automatically catch steel pipe, fixing split bolt one end, the opposite-pulled bolt that only need carry out other end reinforcing has produced.
As shown in Figure 1, be threaded respectively butterfly button 2 and 3, two butterfly buttons 2 of nut of the two ends of screw rod 1 arrange the using method of conventional split bolt in opposite directions.This split bolt, when each construction, in the both sides of wall, need two people to construct simultaneously, when inserting a screw rod 1 in wooden form 7 and time stupefied (lumps of wood) 8 holes, the constructor of both sides lays two horizontal steel tubes 9 simultaneously, puts butterfly button 2 and nut 3, and is fixed, 10 is PVC sleeve pipe, and 6 is cast-in-place concrete wall.This construction method, needs two people's work compounds, and time-consuming, work efficiency is not high; Because of this kind of split bolt, there is screw thread at two ends, when installing and removing, need twice nut of mounting or dismounting, and nut quantity consumption is large, and thread damage rate is high.As can be seen from the above this construction method, overall efficiency is not high, and materials'use rate is not high.
Summary of the invention
The object of the invention is in order to overcome the deficiencies in the prior art the fixed split bolt in one end that provides a kind of and raise the efficiency, reduce costs.
The object of the present invention is achieved like this: the fixed split bolt in one end, comprise screw rod, butterfly button and nut, screw thread is set on screw rod, the quantity of described butterfly button is one, the quantity of nut is one, described screw thread is arranged on one end of screw rod, and butterfly button and nut are threaded in one end that screw rod arranges screw thread; Described screw rod is welded and fixed bar away from one end of screw thread, the middle part of fixed bar and screw rod welding, and the end disjunctor of fixed bar arranges bending bar, and bending bar is arranged on fixed bar towards a side of screw rod.
In use, from template one side of wall, penetrate Screw arbor with nut at both-ends, and horizontal steel tube is placed on respectively to the both sides up and down of the horizon bar of Screw arbor with nut at both-ends, then arrive the another side of wall, the same by normal construction operation work, placing steel tubes, butterfly button and nut.Construction has several lower several advantages like this:
1, because fixed end has welded fixed bar and the bending bar by Φ 14 reinforcement fabrications, to limit two horizontal steel tubes, and rigidity is high.Saved 50% butterfly button.
2, with fixed end, replace a butterfly button and a nut, un-slipped, construction quality is good, and the workmanship defect causing because of stripped thread has reduced 50%.
3, nut and butterfly button, for construction small piece material, are easily lost, and use this fixed end, and the loss of construction small piece material saves 50%.
4,, because fixed end inserts within the walls, when removing, same saving manually, has improved efficiency of construction.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing product use occasion.
Fig. 2 is a kind of structural representation of the present invention.
Fig. 3 is the structural representation of use occasion of the present invention.
The specific embodiment
As shown in Figure 2, for the fixed split bolt in one end, comprise screw rod 1, one end of screw rod 1 arranges screw thread 1-1, the threaded one end that screw rod 1 arranges screw thread 1-1 connects butterfly button 2 and nut 3, and screw rod 1 is welded and fixed bar 4 away from one end of screw thread 1-1, the middle part of fixed bar 4 and screw rod 1 welding, the lower end disjunctor of fixed bar 4 arranges bending bar 5, and bending bar 5 is arranged on fixed bar 4 towards a side of screw rod 1.
As shown in Figure 3,6 is cast-in-place concrete wall, and 7 is wooden form, and 8 is time stupefied (lumps of wood), and 9 is main stupefied (steel pipe), and 10 is PVC sleeve pipe.This split bolt has made threaded one end into by original two ends screw thread, and generation, while using with the reinforcing bar elbow welding, is pierced into screw rod from wall form hole one side, simultaneously can fix two horizontal steel tubes by the bent-up bar below screw rod and screw rod, convenient construction, saves artificial, this end is without anchor upper cap nut simultaneously, also improved work efficiency, end is used a butterfly button less, saves the butterfly button of half, saved cost, and this place is welding point, there will not be the situation of nut stripped thread, improved construction quality.
