Abstract

The utility model discloses a retained exterior wall strengthening device. The device is characterized by comprising a ground scaffold, a construction bent, an outer framework and an inner framework, wherein the ground scaffold is built outside the retained exterior wall; the full framing construction bent is built inside the retained exterior wall; the outer framework is arranged over the outside of the retained exterior wall; the inner framework is arranged over the inside of a strengthening wall body in the retained exterior wall; and the ground scaffold, the outer framework, the inner framework and the construction bent are mutually communicated in door and window holes of the retained exterior wall to be a whole. Used in the utility model, a method of matching the construction scaffold with the framework to hoop the exterior wall is simple and easy for operation, thus saving construction period and cost and simultaneously being beneficial to the stability of an old wall. The method is simple and convenient in operation and low in cost.

Description

Keep the exterior wall bracing means

Technical field

The utility model relates to a kind of building top structure construction reinforcing technique, specifically discloses a kind of reservation exterior wall bracing means.

Background technology

In outstanding historical protective buildings improvement project, when needs keep exterior wall, again structure replacing is carried out in its inside simultaneously, in the internal construction displacement with during to the exterior wall seismic hardening, the monolithic stability of guaranteeing to keep exterior wall is most important.

Carry out the inside reconstruction at building; under the situation that exterior wall need keep; current way commonly used is to adopt the one side formwork construction technology or adopt split bolt perforation construction on exterior wall, can't effectively protect the stable while of exterior wall self to carry out certain destruction to keeping exterior wall again like this when exterior wall self is reinforced.

Summary of the invention

Technical problem to be solved in the utility model provides a kind ofly promptly can protect exterior wall, can satisfy again and reinforce the reservation exterior wall bracing means that requires, thereby overcome the above-mentioned defective that prior art exists.

The technical scheme of the utility model technical solution problem is as follows:

A kind of reservation exterior wall bracing means, it is characterized in that, comprise land scaffold, the construction framed bent, exterior sheathing and inner formword, the described scaffold building that lands is keeping the exterior wall outside, described full hall construction framed bent is set up and is being kept inner side of outer wall, described exterior sheathing is covered in and keeps the exterior wall outside, and described inner formword is covered in and keeps the outer inboard of reinforcing wall within the walls, and described scaffold, exterior sheathing, inner formword and the construction framed bent of landing is interconnected and is one keeping exterior wall door and window hole.

By above disclosed technical scheme as can be known; the utility model lands scaffold by erection construction outside reconstruction Lao Lou; set up full hall construction framed bent in inside; utilize a determining deviation door and window hole to be communicated with interior out-mould scaffold; use inner and outer template to wale exterior wall simultaneously in protection exterior wall inside and outside simultaneously; and utilize a determining deviation door and window hole to be communicated with inner and outer template and reinforce steel pipe and be linked to be integral body with inside full hall construction framed bent simultaneously; thereby play when exterior wall is reinforced as construction formwork, when internal construction is replaced, play and reinforce and the effect of protection exterior wall.

It is simple to operation to use construction scaffolding to cooperate template to wale the method for exterior wall, has saved duration and expense, simultaneously also favourable old wall stable.This method is easy and simple to handle and expense is low.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described further.

As shown in Figure 1 and Figure 2, the utility model keeps the exterior wall bracing means, comprise and land scaffold 2, a full hall construction framed bent 3, exterior sheathing and inner formword, the described scaffold 2 that lands is set up in reservation exterior wall 1 outside, described full hall construction framed bent 3 is set up and is being kept exterior wall 1 inboard, described exterior sheathing is covered in and keeps exterior wall 1 outside, described inner formword is covered in and keeps the outer inboard of reinforcing wall 6 within the walls, and described scaffold 2, exterior sheathing, inner formword and the full hall construction framed bent 3 of landing is interconnected and is one keeping exterior wall door and window hole.

Described exterior sheathing comprises nine clamping plate 4 and flitch 5, and described exterior sheathing is waled the reservation exterior wall by steel tube fastener 9.Described inner formword comprises nine clamping plate 4 and flitch 5, and described inner formword is waled the reservation exterior wall by steel tube fastener 9.

Keep exterior wall protection strengthening construction flow process:

A, the outside is covered with the flitch of the thick nine clamping plate templates of 20mm and 50 * 100mm in keeping exterior wall, and the steel pipe of employing Φ 48 * 3.5mm fixes, and the steel pipe spacing is selected according to wall thickness;

B, set up full hall construction framed bent keeping exterior wall 1 inside, set up routine and land scaffold (internal force bar with keep exterior wall keep effective spacing 300mm at least) keeping exterior wall 1 outside, and crus mediale hand framed bent steel pipe, the inner side template steel pipe door and window hole by former Lao Lou one determining deviation is connected with exterior wall scaffold with the outboard template steel pipe, wale the template and the flitch (accompanying drawing 1) that overlay on the exterior wall in this way;

The out-mould scaffold steel pipe is communicated with the back and is communicated with the both sides exterior wall with re-using long steel pipe in c, the exterior wall, makes an outside circle construction scaffolding, exterior wall hardened system and internal construction framed bent be linked to be integral body;

D, carry out exterior wall seismic hardening and inner displacement construction.
