Abstract

The utility model relates to the building construction field and provides a foundation bolt box with a dense steel mesh. The foundation bolt box with the dense steel mesh comprises a box body and is characterized in that the box body comprises two main frame plates which are symmetrically arranged up and down, at least four stand columns which are distributed in a rectangular shape are arranged on the side walls inside the main frame plates, a plurality of auxiliary frame plates are arranged on the stand columns between an upper main frame plate and a lower main frame plate, and a plurality of layers of steel meshes are coated on the outer side walls of the box body. The foundation bolt box with the dense steel mesh solves the problems that a traditional ultra-deep foundation bolt box is required to be pulled out in the process of construction of reserving bolt holes, the foundation bolt box is pulled out prematurely to cause collapse of the bolt holes, the foundation bolt box is pulled out too late so that the foundation bolt box can not be pulled out because of large friction force, material consumption is large, installation is difficulty, cost is high, and the like. The foundation bolt box with the dense steel mesh is mainly used to reserve ultra-deep foundation bolt holes for equipment foundations in building construction.

Description

A kind of dense mesh stone bolt box

(i) technical field: the utility model relates to the realm of building construction, especially a kind of dense mesh stone bolt box.

(ii) background technology: in industrial construction, often there are the bolt of equipment and the connectivity problem of concrete foundation, due to directly by the stone bolt Transducers Embedded in Concrete of equipment, stone bolt does not have movable leeway, civil engineering is very difficult, and can not meet the requirement that equipment is installed, so the way of industrial normal employing backup land bolt holes in base concrete solves this difficult problem.

At present, in industrial construction, the method for backup land bolt holes has two kinds, and the first is to adopt wooden form to be made into pre-embedded bolt box (as shown in Figure 1); The second is to adopt steel plate to be made into the built-in bolt box of " eight " font (as shown in Figure 2).Adopt these two kinds of methods all to have following problem: (1) employing method one, when the bolt hole degree of depth is larger, wooden form is extracted difficulty, need to be in the situation that the moderate strength of concrete be chosen the pre-embedded bolt box, can cause too early bolt hole to subside, after causing the frictional force between bolt box and foundation concrete can not pull out out too greatly late; (2) adopt method two, the built-in bolt box of " eight " font of making of steel plate, weight is larger, and difficulty is installed, high material consumption, cost is higher.Therefore, designing a kind of stone bolt box that can be good at addressing the above problem extremely is necessary.

(iii) summary of the invention: the purpose of this utility model be exactly to solve that traditional super dark stone bolt box needs to extract in the process of construction prepared screw-bolt hole, the stone bolt box extract too early easily cause bolt hole collapse hole, stone bolt box can be because frictional force can not be pulled out out too greatly after extracting late, high material consumption, installation difficulty and the problem such as cost is higher, a kind of dense mesh stone bolt box is provided.

Concrete scheme of the present utility model is: for traditional stone bolt box, improved, it has box body, it is characterized in that: described box body includes two blocks of main frame plates that are arranged symmetrically with up and down, main frame intralamellar part sidewall at least is equipped with four rectangular columns of arranging, be positioned on column some auxiliary frame frame plates are housed between upper and lower main frame plate, and also be coated with some layers of gauze wire cloth on the lateral wall of box body.

The plate of main frame described in the utility model is square, by the reinforcing bar of Ф 16, is bent and is formed.

Column described in the utility model adopts the reinforcing bar of Ф 16～Ф 22, and column is arranged vertically downward.

The frame plate of auxiliary frame described in the utility model is square, by the reinforcing bar of Ф 6, is bent and is formed.

Gauze wire cloth described in the utility model adopts 18～25 purpose gauze wire cloths.

For the plan-position of calibration bolt box, on the upper outside of box body described in the utility model wall, bracing frame is housed, bracing frame is " well " word structure, is that the reinforcing bar by four Ф 20～Ф 25 surrounds.

For the verticality of calibration bolt box, the bottom of box body described in the utility model is positioned on column is equipped with four feets, and the feet bottom is opened towards the outside and is stool leg shape structure.

The utility model is simple in structure, easy to use, directly bolt box is embedded in concrete, need not extract, make the skeleton of bolt box and can gather materials on the spot, can rationally utilize on-the-spot reinforcing bar leftover bits and pieces, reduce construction cost, accelerated construction speed, brought huge economic benefit.

(iv) accompanying drawing explanation:

Fig. 1 is the front view of traditional pre-embedded bolt box;

Fig. 2 is the front view of the built-in bolt box of traditional " eight " font;

Fig. 3 is main sectional view of the present utility model;

Fig. 4 is the A-A sectional view of Fig. 3.

In figure: 1-main frame plate, 2-column, 3-bracing frame, 4-gauze wire cloth, 5-auxiliary frame frame plate, 6-feet.

(v) the specific embodiment:

Referring to Fig. 3 and Fig. 4, the utlity model has box body, particularly: described box body includes two blocks of main frame plates 1 that are arranged symmetrically with up and down, and main frame plate 1 is square, by the reinforcing bar of Ф 16, is bent and is formed; Four columns 2 vertically downward are equipped with at the inner four jiaos of places of two main frame plates 1, and this column 2 adopts the reinforcing bar of Ф 16～Ф 22; Be positioned on column 2 six auxiliary frame frame plates 5 are housed between upper and lower main frame plate 1, this auxiliary frame frame plate 5 is square, by the reinforcing bar of Ф 6, is bent and is formed; And also be coated with three layer of 18～25 purpose gauze wire cloth 4 on the lateral wall of box body.

On the upper outside of box body described in the present embodiment wall, bracing frame 3 is housed, bracing frame 3 is " well " word structure, is that the reinforcing bar by four Ф 20～Ф 25 surrounds; Be positioned on column 2 four feets 6 are housed in the box body bottom, these feet 6 bottoms are opened towards the outside and are stool leg shape structure.

The utility model, in the process of using, first is welded and fixed bracing frame 3 and basic top rebars the plan-position of calibration bolt box; Again feet 6 and the reinforcing bar of basis or side are welded and fixed to the verticality of calibration bolt box; During construction, the bolt box top is exposed to base concrete face 50mm, with concrete in the process that prevents fluid concrete, flow in bolt box, after pouring the base concrete of bolt box, check the degree of depth of bolt box, the superfluous water mud that will overflow in bolt box with simple and easy spoon is drawn out, until the degree of depth of bolt box meets the requirement of projected depth, finally the bolt box top is switched to get final product concordant with concrete surface with cutting machine.
