[0021] In order to make the invention purpose, technical scheme and beneficial effects of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments.

[0022] like Figure 1As shown, a pre-embedded steel bar positioning device is used in conjunction with a steel bar 4, comprising a positioning bracket, the positioning bracket comprising an annular bracket body 1, and at least one upwardly extending positioning sleeve 2 is arranged on the upper surface of the bracket body 1, and the steel bar 4 can be inserted into the positioning sleeve 2.

[0023] When the utility model is used, Figure 2 As shown, in the first use state of the utility model, the utility model is fixed on the ground, and can be inserted into the ground through a plug-in, or directly placed on the ground, and then the steel bar 4 is inserted into the positioning sleeve 2. Since each positioning sleeve 2 extends upward from the top of the bracket body 1, when the steel bar 4 is inserted into the positioning sleeve 2, the verticality of the steel bar 4 after being inserted into the positioning sleeve 2 is guaranteed, and since the steel bar 4 is inserted into the positioning sleeve 2, the position of the steel bar 4 is limited and fixed by the positioning sleeve 2, that is, the utility model achieves the effect of positioning the steel bar 4. In this way, the utility model solves the problem that the prior art must rely on manual straightening, but this will easily lead to position deviations and the verticality of the steel bar 4 is difficult to guarantee.

[0024] Preferably, since the bracket body 1 is an annular bracket body 1, it is convenient to set a plurality of positioning sleeves 2, and it can ensure that each positioning sleeve 2 is set on the same plane. The annular bracket body 1 can be a ring of a conventional shape such as a square, a circle, a triangle or an ellipse, and its interior is hollow, which can save production costs and reduce the overall weight of the utility model. It can also achieve the effect of exhausting the air under the bracket body 1 when the utility model is set.

[0025] More preferably, the distance between two adjacent positioning sleeves 2 is equal, which can ensure the distance between adjacent steel bars 4 and ensure the setting effect of adjacent steel bars 4. Among them, the spacing between adjacent positioning sleeves 2 needs to be determined according to the spacing between steel bars 4, and the size of the utility model can be determined according to the size of the embedded steel bars 4, which should not be too large or too long. If it is too large, concrete will easily block the pipe and the verticality will be difficult to control, and if it is too long, it will easily block the pipe.

[0026] In some embodiments of the present invention, the present invention is made of metal material.

[0027] In some embodiments of the utility model, the plug-in can be at least one positioning foot 3 arranged under the positioning bracket, and the bracket body 1 in the utility model is inserted and fixed in the ground through the positioning foot 3, so as to achieve the effect of fixing and / or limiting the position of the utility model.

[0028] Preferably, the bottom end of the positioning foot 3 is a pointed end, so that it is easier to insert into the ground.

[0029] Moreover, it should be explained here that the land here refers to the location where the utility model is generally used. The land here can also be a flowable liquid object such as wet concrete or soil. After the liquid object is dry, the effect of fixing the utility model can be achieved.

[0030] Further, the number of positioning legs 3 is consistent with the number of positioning sleeves 2, the positioning legs 3 are coaxially arranged with the positioning sleeves 2, and the positioning legs 3 are hollow tubular positioning legs 3. When in use, the positioning bracket is fixed by the positioning legs 3. Since the positioning bracket and the positioning legs 3 are coaxially arranged, and the positioning legs 3 are hollow tubular positioning legs 3, when the steel bar 4 is inserted into the positioning sleeve 2, the connection between the positioning legs 3 and the positioning sleeve 2 can achieve the effect of extending the length of the steel bar 4 that can be inserted into the utility model, that is, the connection between the positioning legs 3 and the positioning sleeve 2 can achieve the insertion of the steel bar 4 into a deeper position of the utility model, increase the contact range between the positioning sleeve 2 and the steel bar 4, better ensure the effect of fixing and positioning the steel bar 4 by the utility model, and avoid the steel bar 4 from tilting after being inserted into the positioning sleeve 2.

[0031] In some embodiments of the present invention, the inner diameter of each positioning sleeve 2 is greater than or equal to the diameter of the steel bar 4. Preferably, the inner diameter of the positioning sleeve 2 is slightly larger than the diameter of the steel bar 4, which not only facilitates the insertion of the steel bar 4 into the positioning sleeve 2, but also prevents the steel bar 4 from escaping from the positioning sleeve 2 and shaking relative to the positioning sleeve 2.

[0032] In some embodiments of the utility model, the utility model is used for pre-embedding of CFG pile heads for soft soil foundation treatment, and four positioning sleeves 2 are arranged on the bracket body 1.

[0033] In detail, CFG is the abbreviation of Cement Fly-ash Gravel, which stands for cement, fly ash and gravel, and is widely used in soft foundation treatment of various projects. The use of industrial waste - fly ash to replace part of the cement greatly reduces the project cost and increases the later strength of the pile body. Through the setting of the flexible cushion layer, the CFG pile composite foundation can achieve uniform settlement and higher bearing capacity. It is the most economical, applicable, fast and reliable new type of cast-in-place pile for reinforcing soft soil foundation.

[0034] Preferably, the length of the positioning sleeve 2 is greater than or equal to one quarter to one third of the length of the steel bar 4 , thereby preventing the steel bar 4 from escaping from the positioning sleeve 2 .

[0035] As an embodiment of the present invention, the diameter of the steel bar 4 is 16 mm, and the length of the steel bar 4 is 5 m.

[0036] The utility model is used for pre-embedded CFG pile heads for soft soil foundation treatment. In general soft soil foundation treatment CFG pile construction, the pile heads are designed with four pre-embedded steel bars 4 with a diameter of 16mm and a length of 5m. Direct manual insertion requires manual straightening, and the position is more likely to deviate, and the verticality is difficult to ensure. In order to ensure the accurate position of the steel bars 4 and ensure the verticality, under the action of the utility model, the construction is easier to ensure the position and verticality of the pre-embedded steel bars 4, meeting the construction quality requirements.

[0037] In some embodiments of the present invention, Figure 3 As shown, in the second usage state of the utility model, multiple embedded steel bar positioning devices 5 can be stacked up and down, and two adjacent embedded steel bar positioning devices 5 are connected by steel bars 4. The utility model can be set at different positions of the steel bars 4 as needed to better ensure the verticality of the steel bars 4.

[0038] Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the utility model.
