Description
Technical Field
The utility model relates to a building construction method, concretely relates to a reinforcing apparatus that is used for extension built-in fitting of utility tunnel lateral wall.
Background
The lengthened embedded part in the side wall of the cast-in-place concrete structure of the comprehensive pipe gallery is fixed, the position of an embedded part steel plate is generally aligned firstly, and then the embedded part anchor bars and the steel bars in the side wall are welded and fixed, so that the embedded part steel plate is fixed in a template. Due to the fact that the side wall template can slightly expand in the concrete pouring process, gaps can be formed between the side template and the embedded part steel plate, and the embedded part is uneven after the concrete on the side wall of the pipe gallery is formed. The surface of the position of the embedded part on the wall is uneven, the quality acceptance is influenced when the embedded part is not at the same elevation and the like, the difficulty in manufacturing and mounting of a subsequent support is increased, and the cost is increased.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that the fixed effect of piping lane lateral wall built-in fitting is poor among the prior art, the problem of shaping unevenness.
In order to solve the above technical problem, the utility model provides a technical means is:
a lengthened embedded part fixing structure for the side wall of an underground comprehensive pipe gallery comprises an embedded part, wall body reinforcing steel bars, a wall body template and template split bolts, wherein the embedded part is formed by fixedly connecting steel plates and anchor bars; the steel plate of the embedded part is provided with bolt holes which are aligned with the bolt holes on the wall template one by one; the front ends of the split bolts are installed in the wall body formwork, and the steel plates of the embedded parts are arranged between the front positioning ribs and the wall body formwork.
The scheme adopts a mode of drilling holes on the steel plates of the embedded parts, the template split bolts are simultaneously used for fixing the embedded parts, and the front positioning ribs effectively fasten the lengthened embedded iron parts and the template surface into a whole so as to ensure the forming quality of the embedded parts; the connection tightness of the embedded iron piece and the side wall template is enhanced, the unevenness of the embedded iron piece and the deviation of different elevations are reduced, and the manufacturing and installation efficiency of the support is improved.
Drawings
FIG. 1 is a design structure diagram of a split bolt of the present invention;
fig. 2 is the fixing structure diagram of the embedded part of the present invention.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, a fixing structure for an elongated embedded iron member on a side wall of an underground comprehensive pipe gallery comprises an embedded member formed by fixedly connecting a steel plate 6 and an anchor bar 5, wall steel bars (between wall formworks on two sides, not shown in the figure), a wall formwork 7 and a split bolt 1 of the formwork.
The middle part of the split bolt 1 is provided with a water stop sheet 3, a rear positioning rib 4 is arranged at a distance of one-half wall thickness backwards by taking the water stop sheet 3 as a midpoint, and a front positioning rib 2 is arranged at a position of one-half wall thickness forwards and retreating from the embedded part steel plate thickness; the steel plates 6 of the embedded parts are provided with bolt holes which are aligned with the bolt holes on the wall body template 7 one by one; the front end of the split bolt 1 is arranged in a wall formwork 7, and a steel plate 6 of an embedded part is arranged between the front positioning rib 2 and the wall formwork 7.
The construction steps of the lengthened embedded part fixing structure are as follows:
step one, each embedded iron part is 6m long, and bolt hole lofting positioning is carried out according to the length of each embedded iron part being 450mm (the bolt hole distance can be adjusted according to the actual situation on site);
drilling holes in the embedded iron piece steel plate 6;
step three, the thickness of the wall body constructed in the example is 400mm, a split screw 1 (phi 12 with a water stop sheet) is prefabricated, a front positioning rib 2 with the thickness of 100mm is welded at the 190mm position of one end of the water stop sheet, a rear positioning rib 4 is welded at the 200mm position of the other end of the water stop sheet, and the front positioning rib and the rear positioning rib are all made of round steel with the thickness of phi 5 mm;
step four, aiming at the elevation position of the design drawing of the embedded part and the position of the bolt hole of the embedded iron part, processing the wall template 7 in advance, and drilling a phi 12 hole on the row plate;
fixing the embedded part to a steel reinforcement framework on the side wall of the pipe gallery according to the requirements of a design drawing;
sixthly, mounting the counter-pulling screw rod 1 to a bolt hole of a steel plate 6 of the embedded part, and tightly attaching the front positioning rib 2 to the back of the steel plate 6 of the embedded part;
and step seven, aligning the bolt holes of the steel plates 6 with the counter-pulling screws of the wall formworks 7, and after the dovetail clamps are screwed, tightening the two sides of the counter-pulling bolts to fix the wall formworks 7 and the steel plates 6.
Step eight, reinforcing the template according to the construction scheme;
and step nine, pouring concrete after the working of the steel bars and the templates is finished.
By adopting the method, the lengthened embedded iron part and the template surface can be fastened into a whole, and the forming quality of the embedded part is ensured; the connection tightness of the embedded iron piece and the side wall template is enhanced, the unevenness of the embedded iron piece and the deviation of different elevations are reduced, and the manufacturing and installation efficiency of the support is improved.
